Method and device in nodes used for wireless communication

[0001] This application is the continuation of the international patent application No. PCT/CN2022/106950, filed on Jul. 21, 2022, and claims the priority benefit of Chinese Patent Application No. 202110828886.9, filed on Jul. 22, 2021, the full disclosure of which is incorporated herein by reference.

[0002] The present application relates to transmission methods and devices in wireless communication systems, and in particular to a transmission scheme and device for flexible transmission direction configurations in wireless communications.

[0003] Application scenarios of future wireless communication systems are becoming increasingly diversified, and different application scenarios have different performance demands on systems. In order to meet different performance requirements of various application scenarios, the 3rd Generation Partner Project (3GPP) Radio Access Network (RAN) #72 plenary decided to conduct the study of New Radio (NR), or what is called fifth Generation (5G). The work Item (WI) of NR was approved at the 3GPP RAN #75 session to standardize the NR. It was decided at the 3GPP RAN #86 Plenary that the Study Item (SI) and the Work Item (WI) of NR Rel-17 should be started, and the SI and WI of NR Rel-18 are expected to be proposed at the 3GPP RAN #94e plenary.

[0004] Enhanced Mobile BroadBand (eMBB), Ultra-reliable and Low Latency Communications (URLLC) and massive Machine Type Communications (mMTC) are three major application scenarios in New Radio (NR) technology.

[0005] In the existing NR system, spectrum resources are statically divided into FDD spectrum and TDD spectrum. As for TDD spectrum, both the base station and the UE work in Half Duplex Mode. Such Half Duplex Mode avoids self-interference and reduces the influence of Cross Link interference, but it also brings about a reduction of resource utilization ratio and a longer delay. In view of these problems, to support flexible duplex mode or variable link directions (Uplink, or Downlink, or Flexible ones) on the TDD spectrum or the FDD spectrum becomes a potential solution.

[0006] To address the issue of configuration of link directions in cases supporting Flexible Duplex Mode, the present application provides a solution. It should be noted that the description in the present application only takes Flexible Duplex Mode as a typical application scenario or example; this application is also applicable to other scenarios confronting similar issues, for instance, scenarios where a link direction changes, or scenarios supporting multi-stage configuration of transmission directions, or those equipped with a more powerful base station or UE, such as a base station or UE that supports intra-frequency full duplex scenarios or is targeted for various application scenarios like eMBB and URLLC, where similar technical effects can be achieved. Additionally, the adoption of a unified solution for various scenarios, including but not limited to eMBB and URLLC scenarios, contributes to the reduction of hardcore complexity and costs. In the case of no conflict, the embodiments of a first node and the characteristics in the embodiments may be applied to a second node, and vice versa. Particularly, for interpretations of the terminology, nouns, functions and variables (unless otherwise specified) in the present application, refer to definitions given in TS36 series, TS38 series and TS37 series of 3GPP specifications.

FIG. 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture of a user plane 350 and a control plane 300. In FIG. 3, the radio protocol architecture for a control plane 300 used for a first node (UE or gNB) and a second node (gNB or UE) is represented by three layers, which are a layer 1, a layer 2 and a layer 3, respectively. The layer 1 (L1) is the lowest layer which performs signal processing functions of various PHY layers. The L1 is called PHY 301 in the present application. The layer 2 (L2) 305 is above the PHY 301, and is in charge of the link between the first node and the second node via the PHY 301. The L2 305 comprises a Medium Access Control (MAC) sublayer 302, a Radio Link Control (RLC) sublayer 303 and a Packet Data Convergence Protocol (PDCP) sublayer 304. All the three sublayers terminate at the second nodes of the network side. The PDCP sublayer 304 provides multiplexing among variable radio bearers and logical channels. The PDCP sublayer 304 provides security by encrypting a packet and provides support for handover of a first node between second nodes. The RLC sublayer 303 provides segmentation and reassembling of a higher-layer packet, retransmission of a lost packet, and reordering of a packet so as to compensate the disordered receiving caused by Hybrid Automatic Repeat reQuest (HARQ). The MAC sublayer 302 provides multiplexing between a logical channel and a transport channel. The MAC sublayer 302 is also responsible for allocating between first nodes various radio resources (i.e., resource block) in a cell. The MAC sublayer 302 is also in charge of HARQ operation. In the control plane 300, The RRC sublayer 306 in the L3 layer is responsible for acquiring radio resources (i.e., radio bearer) and configuring the lower layer using an RRC signaling between the second node and the first node. The radio protocol architecture in the user plane 350 comprises the L1 layer and the L2 layer. In the user plane 350, the radio protocol architecture used for the first node and the second node in a PHY layer 351, a PDCP sublayer 354 of the L2 layer 355, an RLC sublayer 353 of the L2 layer 355 and a MAC sublayer 352 of the L2 layer 355 is almost the same as the radio protocol architecture used for corresponding layers and sublayers in the control plane 300, but the PDCP sublayer 354 also provides header compression used for higher-layer packet to reduce radio transmission overhead. The L2 layer 355 in the user plane 350 also comprises a Service Data Adaptation Protocol (SDAP) sublayer 356, which is in charge of the mapping between QoS streams and a Data Radio Bearer (DRB), so as to support diversified traffics. Although not described in FIG. 3, the first node may comprise several higher layers above the L2 355, such as a network layer (i.e., IP layer) terminated at a P-GW 213 of the network side and an application layer terminated at the other side of the connection (i.e., a peer UE, a server, etc.).

In DL, the controller/processor 440 provides header compression, encryption, packet segmentation and reordering, multiplexing between a logical channel and a transport channel as well as radio resources allocation for the first node 450 based on various priorities. The controller/processor 440 is responsible for HARQ operation, retransmission of a lost packet and a higher layer signaling to the first node 450. The first information block, second information block and third information block in the present application are generated by the controller/processor 440. The transmitting processor 415 performs various signal processing functions used for the L1 (that is, PHY), including coding, interleaving, scrambling, modulation, power control/allocation, pre-coding and physical layer control signaling generation, for example, the generation of a physical-layer signal carrying the first information block, a physical-layer signal carrying the second information block, a physical-layer signal carrying the third information block and the first signaling in the present application is completed in the transmitting processor 415. Modulation symbols that have been generated are divided into parallel streams and each of them is mapped onto a corresponding multicarrier subcarrier and/or multicarrier symbol, and then is mapped by the transmitting processor 415 to the antenna 420 via the transmitter 416 to be transmitted in the form of radio frequency signals. At the receiving end, each receiver 456 receives a radio frequency signal via a corresponding antenna 460, and recovers baseband information modulated onto a radio frequency carrier and provides the baseband information to the receiving processor 452. The receiving processor 452 performs various signal receiving processing functions used for the L1. Signal receiving processing functions include receiving a physical layer signal carrying the first information block, a physical layer signal carrying the second information block, a physical layer signal carrying the third information block and the first signaling in the present application, and demodulating multicarrier symbols in multicarrier symbol streams based on various modulation schemes (i.e., BPSK, QPSK), then de-scrambling, decoding and de-interleaving to recover data or control signal transmitted by the second node 410 on a physical channel, and providing the data and control signal to the controller/processor 490. The controller/processor 490 is in charge of the L2 and above layers, and the controller/processor 490 interprets higher-layer information in the present application. The interpretation includes the first information block, the second information block and the third information block. The controller/processor can be associated with the memory 480 that stores program code and data; the memory 480 may be called a computer readable medium.

[0398] In UL transmission, which is similar to DL, higher-layer information, including that carried in the target signal in the present application, upon generation in the controller/processor 490, is through the transmitting processor 455 to perform signal transmitting processing functions used for the L1 (that is, PHY), for instance, a physical layer signal of the target signal is mapped to the antenna 460 via the transmitter 456 from the transmitting processor 455 and transmitted in the form of radio frequency signal. The receiver 416 receives a radio frequency signal via a corresponding antenna 420, and each receiver 416 recovers baseband information modulated onto a radio frequency carrier and provides the baseband information to the receiving processor 412. The receiving processor 412 performs various signal reception processing functions used for L1 (i.e., PHY), including receiving a physical layer signal carrying the target signal in the present application and then providing data and/or control signal to the controller/processor 440. Functions of the L2 performed by the controller/processor 440 include interpreting higher-layer information, including higher-layer information carried in the target signal in the present application. The controller/processor can be associated with the buffer 430 that stores program code and data; the buffer 430 may be called a computer readable medium.
