Description

Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and in particular to methods and apparatus for monitoring PDCCH in wireless communication systems. Background Technology

[0002] Multi-antenna technology is a key technology in 3GPP (3rd Generation Partner Project) LTE (Long-term Evolution) and NR (New Radio) systems. It gains additional spatial freedom by configuring multiple antennas at communication nodes, such as base stations or user equipment (UEs). Multiple antennas, through beamforming, form beams pointing in a specific direction to improve communication quality. The NR R (Release)-16 standard already supported base stations transmitting radio signals through one or more transceiver nodes or antenna panels, and the later NR R (Release)-17 standard also supported user equipment (UEs) transmitting radio signals through one or more transceiver node antenna panels.

[0003] The NRR (Release)-17 standard also supports the use of DCI (Downlink Control Information) signaling to indicate a TCI (Transmission configuration indicator) state applied to CORESET (Control Resource Set) and PDSCH (Physical Downlink Shared Channel). Summary of the Invention

[0004] The inventors discovered through research that, when DCI signaling indicates TCI status, the problem to be solved is how to identify one or more CORESETs from multiple CORESETs that are monitoring PDCCHs among multiple overlapping PDCCH monitoring occasions.

[0005] To address the aforementioned issues, this application discloses a solution. It should be noted that although the above description uses a multi-TRP / panel transmission and control channel transmission scenario as an example, this application is also applicable to other scenarios such as single-TRP / panel transmission of other physical layer channels, carrier aggregation, or Internet of Things (V2X), achieving similar technical effects to the multi-TRP / panel transmission and control channel transmission scenario. Furthermore, adopting a unified solution for different scenarios (including but not limited to multi-TRP / panel transmission, single-TRP / panel transmission, control channels, other physical layer channels, carrier aggregation, and Internet of Things) helps reduce hardware complexity and cost. Where there is no conflict, the embodiments and features in the embodiments of the first node of this application can be applied to the second node, and vice versa. Where there is no conflict, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0006] To address the above, this application discloses a solution. It should be noted that the description in this application uses energy saving as a typical application scenario or example; the technical solution in this application is also applicable to other scenarios facing similar problems (such as other non-base station energy-saving scenarios, including but not limited to capacity enhancement systems, short-range communication systems, unlicensed frequency domain communication, IoT (Internet of Things), URLLC (Ultra Reliable Low Latency Communication) networks, vehicle-to-everything (V2X) networks, etc.), and can achieve similar technical effects. Furthermore, adopting a unified solution for different scenarios (including but not limited to base station energy-saving scenarios) also helps reduce hardware complexity and cost. Where there is no conflict, the embodiments and features in the embodiments of the first node of this application can be applied to the second node, and vice versa.

[0007] In particular, the interpretation of terms, nouns, functions, and variables in this application (unless otherwise specified) can be found in the definitions of the 3GPP specification protocols TS36, TS38, and TS37 series. Where necessary, 3GPP standards TS38.211, TS38.212, TS38.213, TS38.214, TS38.215, TS38.321, TS38.331, TS38.305, TS38.304, and TS37.355 can be consulted to aid in understanding this application.

[0224] Example 3 illustrates a schematic diagram of an embodiment of a wireless protocol architecture for a user plane and a control plane according to this application, as shown in the attached diagram. Figure 3 As shown. Figure 3 This is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane 350 and the control plane 300. Figure 3The radio protocol architecture of the control plane 300 between the first communication node device (UE, gNB, or RSU in V2X) and the second communication node device (gNB, UE, or RSU in V2X), or between two UEs, is illustrated 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. Layer 1 will be referred to as PHY 301 in this document. Layer 2 (L2 layer) 305, above PHY 301, is responsible for the link between the first and second communication node devices, or between two UEs. Layer 2 305 includes the MAC (Medium Access Control) sublayer 302, the RLC (Radio Link Control) sublayer 303, and the PDCP (Packet Data Convergence Protocol) sublayer 304, which terminate at the second communication node device. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. PDCP sublayer 304 also provides security through encrypted data packets and supports cross-cell mobility between second communication node devices and the first communication node device. RLC sublayer 303 provides upper layer data packet segmentation and reassembly, retransmission of lost data packets, and data packet reordering to compensate for out-of-order reception due to HARQ. MAC sublayer 302 provides multiplexing between the logical and transport channels. MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) within a cell between the first communication node devices. MAC sublayer 302 is also responsible for HARQ operations. The RRC (Radio Resource Control) sublayer 306 in Layer 3 (L3) of the control plane 300 is responsible for acquiring radio resources (i.e., radio bearers) and configuring the lower layer using RRC signaling between the second and first communication node devices. The radio protocol architecture of user plane 350 includes layer 1 (L1 layer) and layer 2 (L2 layer). The radio protocol architecture for the first and second communication node devices in user plane 350 is largely the same as the corresponding layers and sublayers in control plane 300 for physical layer 351, PDCP sublayer 354 in L2 layer 355, RLC sublayer 353 in L2 layer 355 and MAC sublayer 352 in L2 layer 355. However, 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, which is responsible for mapping between QoS streams and data radio bearers (DRBs) to support service diversity. Although not illustrated, the first communication node device may have several upper layers above the L2 layer 355, including a network layer (e.g., IP layer) terminating at the P-GW on the network side and an application layer terminating at the other end of the connection (e.g., a remote UE, server, etc.).

[0230] Example 4

[0231] Example 4 illustrates a schematic diagram of a first communication device and a second communication device according to an embodiment of this application, as shown in the attached diagram. Figure 4 As shown. (Attached) Figure 4 This is a block diagram of a first communication device 410 and a second communication device 450 communicating with each other in an access network.

[0232] The first communication device 410 includes a controller / processor 475, a memory 476, a receiver processor 470, a transmitter processor 416, a multi-antenna receiver processor 472, a multi-antenna transmitter processor 471, a transmitter / receiver 418, and an antenna 420.

[0233] The second communication device 450 includes a controller / processor 459, a memory 460, a data source 467, a transmitting processor 468, a receiving processor 456, a multi-antenna transmitting processor 457, a multi-antenna receiving processor 458, a transmitter / receiver 454, and an antenna 452.

[0234] In the transmission from the first communication device 410 to the second communication device 450, at the first communication device 410, upper-layer data packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements L2 layer functionality. In the L2 layer, the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the second communication device 450 based on various priority metrics. The controller / processor 475 is also responsible for HARQ operation, retransmission of lost packets, and signaling to the second communication device 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for the L1 layer (i.e., the physical layer). Transmit processor 416 performs encoding and interleaving to facilitate forward error correction (FEC) at the second communication device 450, and constellation mapping based on various modulation schemes (e.g., Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), M-Phase Shift Keying (M-PSK), M-QAM). Multi-antenna transmit processor 471 performs digital spatial precoding on the encoded and modulated symbols, including codebook-based and non-codebook-based precoding, and beamforming processing, generating one or more parallel streams. Transmit processor 416 then maps each parallel stream to a subcarrier, multiplexes the modulated symbols with a reference signal (e.g., a pilot) in the time and / or frequency domains, and subsequently uses Inverse Fast Fourier Transform (IFFT) to generate a physical channel carrying the time-domain multicarrier symbol stream. Multi-antenna transmit processor 471 then performs transmit analog precoding / beamforming operations on the time-domain multicarrier symbol stream. Each transmitter 418 converts the baseband multicarrier symbol stream provided by the multi-antenna transmitter processor 471 into an radio frequency stream, which is then provided to different antennas 420.

[0235] In the transmission from the first communication device 410 to the second communication device 450, at the second communication device 450, each receiver 454 receives a signal through its corresponding antenna 452. Each receiver 454 recovers the information modulated onto the radio frequency carrier and converts the radio frequency stream into a baseband multicarrier symbol stream, which is then provided to the receiver processor 456. The receiver processor 456 and the multi-antenna receiver processor 458 implement various signal processing functions of the L1 layer. The multi-antenna receiver processor 458 performs receive analog precoding / beamforming operations on the baseband multicarrier symbol stream from the receiver 454. The receiver processor 456 uses a Fast Fourier Transform (FFT) to convert the baseband multicarrier symbol stream after the receive analog precoding / beamforming operations from the time domain to the frequency domain. In the frequency domain, the physical layer data signal and the reference signal are demultiplexed by the receiver processor 456, where the reference signal is used for channel estimation, and the data signal is recovered in the multi-antenna receiver processor 458 after multi-antenna detection to recover any parallel stream destined for the second communication device 450. Symbols on each parallel stream are demodulated and recovered in the receive processor 456, generating soft decisions. The receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper-layer data and control signals transmitted by the first communication device 410 over the physical channel. The upper-layer data and control signals are then provided to the controller / processor 459. The controller / processor 459 implements the functions of Layer 2. The controller / processor 459 may be associated with a memory 460 storing program code and data. The memory 460 may be referred to as computer-readable media. In the DL (Downlink), the controller / processor 459 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transmission and logical channels to recover upper-layer packets from the core network. The upper-layer packets are then provided to all protocol layers above Layer 2. Various control signals may also be provided to Layer 3 for Layer 3 processing. The controller / processor 459 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0236] In the transmission from the second communication device 450 to the first communication device 410, at the second communication device 450, a data source 467 is used to provide upper-layer data packets to the controller / processor 459. The data source 467 represents all protocol layers above the L2 layer. Similar to the transmission functions at the first communication device 410 described in the DL, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on the radio resource allocation of the first communication device 410, implementing L2 layer functions for the user plane and control plane. The controller / processor 459 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the first communication device 410. Transmit processor 468 performs modulation mapping and channel coding processing, while multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based and non-codebook-based precoding, and beamforming processing. Subsequently, transmit processor 468 modulates the generated parallel stream into a multi-carrier / single-carrier symbol stream. After analog precoding / beamforming operations in multi-antenna transmit processor 457, the stream is provided to different antennas 452 via transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by multi-antenna transmit processor 457 into a radio frequency symbol stream before providing it to antenna 452.

[0237] In the transmission from the second communication device 450 to the first communication device 410, the function at the first communication device 410 is similar to the receiving function at the second communication device 450 described in the transmission from the first communication device 410 to the second communication device 450. Each receiver 418 receives radio frequency signals through its corresponding antenna 420, converts the received radio frequency signals into baseband signals, and provides the baseband signals to the multi-antenna receiving processor 472 and the receiving processor 470. The receiving processor 470 and the multi-antenna receiving processor 472 jointly implement the L1 layer functions. The controller / processor 475 implements the L2 layer functions. The controller / processor 475 may be associated with a memory 476 that stores program code and data. The memory 476 may be referred to as computer-readable media. The controller / processor 475 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transmission and logical channels to recover upper-layer data packets from the second communication device 450. The upper-layer data packets from the controller / processor 475 may be provided to the core network. The controller / processor 475 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operation.

[0331] In embodiment 11, at least one of the plurality of CORESETs belongs to a first CORESET pool, and at least one of the plurality of CORESETs belongs to a second CORESET pool. The first CORESET pool includes at least one CORESET, and the second CORESET pool includes at least one CORESET. The first CORESET pool and the second CORESET pool are different. The first TCI state is applied to at least one CORESET in the first CORESET pool, and the second TCI state is applied to at least one CORESET in the second CORESET pool.

[0332] As one embodiment, the first CORESET pool includes at least one CORESET from one or more cells in the first cell group, and the second CORESET pool includes at least one CORESET from one or more cells in the first cell group.

[0333] As an example, at least one CORESET in each cell of the first cell group belongs to either the first CORESET pool or the second CORESET pool.

[0334] As an example, the first CORESET pool and the second CORESET pool belong to the same cell in the first cell group.

[0335] As an example, the first cell group includes more than one cell, and at least two CORESETs in the first CORESET pool belong to different cells in the first cell group.

[0336] As one embodiment, the first cell group includes more than one cell, and at least two CORESETs in the second CORESET pool belong to different cells including the first cell group.

[0337] As one embodiment, the first cell group includes more than one cell; at least two CORESETs in the first CORESET pool belong to different cells in the first cell group, or at least two CORESETs in the second CORESET pool belong to different cells in the first cell group.

[0338] As an example, any one of the plurality of CORESETs belongs to either the first CORESET pool or the second CORESET pool.

[0339] As an example, some of the multiple CORESETs belong to either the first CORESET pool or the second CORESET pool.

[0340] As an example, a CORESET associated with the first TCI state belongs to the first CORESET pool, and a CORESET associated with the second TCI state belongs to the second CORESET pool.

[0341] As an example, any CORESET in the first CORESET pool is associated with the first TCI state, and any CORESET in the second CORESET pool is associated with the second TCI state.

In the appendix Figure 13 In the first node device, the processing unit 1200 includes a first receiver 1201 and a first processor 1202.

[0478] As one example, the first node device is a user equipment.

[0479] As an example, the first node device is a relay node device.

[0480] As an example, the first receiver 1201 includes at least one of the following in embodiment 4: {antenna 452, receiver 454, receiver processor 456, multi-antenna receiver processor 458, controller / processor 459, memory 460, data source 467}.
