Description

A method and device in a node for wireless communication Technical Field

[0001] The present application relates to a transmission method and apparatus in a wireless communication system, and more particularly to a transmission scheme and apparatus with flexible transmission direction configuration in wireless communication. Background Art

[0002] The application scenarios of future wireless communication systems are becoming increasingly diverse, and different scenarios place varying performance requirements on the systems. To meet the diverse performance demands of various application scenarios, the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) Plenary #72 decided to conduct research on New Radio (NR) (or 5G). The WI (Work Item) for New Radio (NR) was approved at the 3GPP RAN #75 Plenary Meeting, initiating standardization work on NR. The 3GPP RAN #86 Plenary Meeting decided to initiate work on the SI (Study Item) and WI (Work Item) for NR Rel-17, and plans to establish the SI and WI for NR Rel-18 at the 3GPP RAN #94e Plenary Meeting.

[0003] Among the new air interface technologies, enhanced mobile broadband (eMBB), ultra-reliable and low-latency communications (URLLC), and massive machine type communications (mMTC) are the three main application scenarios.

[0004] Summary of the Invention

[0005] In existing NR systems, spectrum resources are statically divided into FDD and TDD spectrum. For TDD spectrum, both base stations and user equipment operate in half-duplex mode. This half-duplex mode avoids self-interference and mitigates the impact of cross-link interference, but it also reduces resource utilization and increases latency. To address these issues, supporting flexible duplex modes in either TDD or FDD spectrum is a possible solution.

[0006] The present application discloses a solution to the problem of determining a beam or a corresponding TCI state in supporting a flexible duplex mode. It should be noted that in the description of this application, the flexible duplex mode is only used as a typical application scenario or example; this application is also applicable to other scenarios facing similar problems (for example, scenarios where the link direction changes, or other scenarios that support multi-level configuration of the transmission direction, or base stations or user equipment with stronger capabilities, such as scenarios that support co-frequency full-duplex, or for different application scenarios, such as eMBB and URLLC, similar technical effects can be achieved. In addition, this application can also solve the problem of determining parameters other than beam or TCI states, such as default power parameters, default scheduling parameters, etc. The use of a unified solution for different scenarios (including but not limited to eMBB and URLLC scenarios) or different application parameters also helps to reduce hardware complexity and cost. In the absence of conflict, the embodiments and features in the first node device of this application can be applied to the second node device, and vice versa. In particular, the interpretation of terminology, nouns, functions, and variables in this application (unless otherwise specified) can refer to the definitions in the 3GPP specification protocols TS38 series and TS37 series.

[0307] Example 3

[0308] Embodiment 3 illustrates a schematic diagram of an embodiment of a radio protocol architecture for a user plane and a control plane according to the present application, as shown in FIG3 . FIG3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane 350 and a control plane 300. FIG3 illustrates the radio protocol architecture of the control plane 300 for a first node device (UE or gNB) and a second node device (gNB or UE) using three layers: Layer 1, Layer 2, and Layer 3. Layer 1 (L1 layer) is the lowest layer and implements various PHY (physical layer) signal processing functions. The L1 layer will be referred to herein as PHY 301. Layer 2 (L2 layer) 305 is above PHY 301 and is responsible for the link between the first node device and the second node device via PHY 301. L2 layer 305 includes a MAC (Medium Access Control) sublayer 302, an RLC (Radio Link Control) sublayer 303, and a PDCP (Packet Data Convergence Protocol) sublayer 304. These sublayers terminate at the second node device. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides security by encrypting data packets, and provides support for inter-zone mobility of the first node device between the second node devices. The RLC sublayer 303 provides segmentation and reassembly of upper layer data packets, retransmission of lost data packets, and reordering of data packets to compensate for out-of-order reception due to HARQ. The MAC sublayer 302 provides multiplexing between logical and transport channels. The MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) in a cell between the first node devices. The MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in Layer 3 (L3 layer) in the control plane 300 is responsible for obtaining radio resources (i.e., radio bearers) and configuring the lower layers using RRC signaling between the second node device and the first node device. The radio protocol architecture of the user plane 350 includes layer 1 (L1 layer) and layer 2 (L2 layer). The radio protocol architecture for the first node device and the second node device in the user plane 350 is substantially the same as the corresponding layers and sublayers in the control plane 300 for the physical layer 351, the PDCP sublayer 354 in the L2 layer 355, the RLC sublayer 353 in the L2 layer 355, and the MAC sublayer 352 in the L2 layer 355, but the PDCP sublayer 354 also provides header compression for upper layer data packets to reduce radio transmission overhead.The L2 layer 355 in the user plane 350 also includes an SDAP (Service Data Adaptation Protocol) sublayer 356. The SDAP sublayer 356 is responsible for mapping between QoS flows and data radio bearers (DRBs) to support service diversity. Although not shown, the first node device may have several upper layers above the L2 layer 355, including a network layer (e.g., an IP layer) terminated at the P-GW on the network side and an application layer terminated at the other end of the connection (e.g., a remote UE, a server, etc.).

[0310] As an embodiment, the wireless protocol architecture in FIG3 is applicable to the second node device in this application.

[0316] Example 4

[0317] Example 4 shows a schematic diagram of a first node device and a second node device according to an embodiment of the present application, as shown in FIG4 .

[0318] The first node device (450) may include a controller / processor 490, a data source / buffer 480, a receiving processor 452, a transmitter / receiver 456 and a transmitting processor 455, and the transmitter / receiver 456 includes an antenna 460.

[0319] The second node device ( 410 ) may include a controller / processor 440 , a data source / buffer 430 , a receiving processor 412 , a transmitter / receiver 416 and a transmitting processor 415 , wherein the transmitter / receiver 416 includes an antenna 420 .

[0320] In the DL (Downlink), upper layer packets are provided to the controller / processor 440. The controller / processor 440 implements the functions of the L2 layer and above. In the DL, the controller / processor 440 provides packet header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the first node device 450 based on various priority metrics. The controller / processor 440 is also responsible for HARQ operations, retransmission of lost packets, and high-layer signaling to the first node device 450. The high-layer information carried by the first information block, the first signal (if the first signal carries high-layer information), and the second information block in this application is generated by the controller / processor 440. The transmit processor 415 implements various signal processing functions for the L1 layer (i.e., the physical layer), including coding, interleaving, scrambling, modulation, power control / allocation, precoding, and physical layer control signaling generation. For example, the physical layer signal carrying the first information block, the first signal, and the physical layer signal carrying the second information block are completed by the transmit processor 415. The generated modulated symbols are divided into parallel streams and each stream is mapped to a corresponding multi-carrier subcarrier and / or multi-carrier symbol. The symbols are then mapped by the transmit processor 415 to the antenna 420 via the transmitter 416 and transmitted in the form of RF signals. At the receiving end, each receiver 456 receives the RF signal via its corresponding antenna 460, recovers the baseband information modulated onto the RF carrier, and provides the baseband information to the receive processor 452. The receive processor 452 implements various L1 layer signal reception processing functions. The signal reception processing functions include receiving the physical layer signal carrying the first information block in this application, the first signal in this application, and the physical layer signal carrying the second information block in this application, demodulating the multi-carrier symbols in the multi-carrier symbol stream based on various modulation schemes (e.g., binary phase shift keying (BPSK) and quadrature phase shift keying (QPSK)), and then descrambling, decoding, and deinterleaving to recover the data or control signals transmitted by the second node device 410 on the physical channel. The data and control signals are then provided to the controller / processor 490. The controller / processor 490 is responsible for L2 and above layers and interprets higher-level information. This includes interpreting the higher-level information carried by the first information block, the first signal (if the first signal carries higher-level information), and the second information block. The controller / processor may be associated with a memory 480 that stores program code and data. Memory 480 may be referred to as a computer-readable medium.

[0321] During uplink (UL) transmission, similar to downlink transmission, higher-layer information, including the higher-layer information carried by the third information block in this application, is generated by the controller / processor 490 and then processed by the transmit processor 455 to perform various signal transmission processing functions for the L1 layer (i.e., physical layer). The physical layer signal carrying the third information block is mapped by the transmit processor 455 via the transmitter 456 to the antenna 460 and transmitted as a radio frequency signal. Receivers 416 receive the radio frequency signal via their corresponding antennas 420. Each receiver 416 recovers the baseband information modulated onto the radio frequency carrier and provides the baseband information to the receive processor 412. The receive processor 412 performs various signal reception processing functions for the L1 layer (i.e., physical layer), including receiving and processing the physical layer signal carrying the third information block in this application, and then provides data and / or control signals to the controller / processor 440. The L2 layer functions implemented by the controller / processor 440 include interpreting higher-layer information, such as the higher-layer information carried by the third information block. The controller / processor may be associated with a buffer 430 that stores program code and data. The buffer 430 may be a computer-readable medium.
