Description

Technical Field

[0001] This application relates to transmission methods and apparatus in wireless communication systems, and more particularly to transmission schemes and apparatus with multiple antennas in wireless communication. Background Technology

[0002] The application scenarios of future wireless communication systems are becoming increasingly diversified, and different application scenarios place different performance requirements on the system. In order to meet the different performance requirements of various application scenarios, the 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) #72 plenary meeting decided to study New Radio (NR) (or 5G). At the 3GPP RAN #75 plenary meeting, the WI (Work Item) for New Radio (NR) was adopted, and the standardization work for NR began.

[0003] In New Radio (NR) technologies, multi-antenna technologies (such as Multiple Input Multiple Output (MIMO), Transmission Reception Point (TRP), and multiple panels) are crucial components. To adapt to more diverse application scenarios and meet higher demands, the 3GPP RAN#86 plenary meeting approved a further enhancement of MIMO under NR, WI, to support more robust, spectrally efficient, and versatile multi-antenna communication for a wider range of applications. Summary of the Invention

[0004] In multi-antenna systems, such as Transmission Reception Point (TRP) communication, the same channel or signal can be transmitted through multiple transmit / receive nodes to enhance transmission robustness. Release 16 (Rel-16) supported TRP transmission for the data channel, and 3GPP plans to introduce TRP transmission for the control channel in Release 17 (Rel-17). After introducing TRP transmission for the control channel (especially in shared spectrum channel access operations), how to use the fallback DCI format to schedule frequency domain resources is a key issue that needs to be addressed.

[0005] To address the aforementioned problems, this application discloses a solution. It should be noted that the description in this application uses a multi-antenna system, particularly a multi-transmitter / receiver node transmission system, as a typical application scenario or example. This application is also applicable to other scenarios facing similar problems (such as scenarios with higher requirements for control channel robustness or coverage, or scenarios requiring PDCCH (Physical Downlink Control Channel) association in addition to multi-transmitter / receiver node transmission, including but not limited to coverage enhancement systems, IoT (Internet of Things), URLLC (Ultra-Reliable Low Latency Communication) networks, and vehicle-to-everything (V2X) networks), achieving similar technical effects. Furthermore, adopting a unified solution for different scenarios (including but not limited to multi-antenna system scenarios) helps reduce hardware complexity and cost, or improve performance.

[0217] Example 3

[0218] 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 user plane 350 and control plane 300. Figure 3The radio protocol architecture for 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. L1 layer will be referred to herein as PHY301. Layer 2 (L2 layer) 305 sits above PHY301 and is responsible for the link between the first and second communication node devices and between the two UEs via PHY301. 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, 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.).

[0229] Example 4

[0230] Example 4 shows schematic diagrams of a first communication device and a second communication device according to this application, as shown in the appendix. Figure 4 As shown. 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.

[0231] 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.

[0232] 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.

[0233] 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 transmission from the first communication device 410 to the second communication device 450, 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 retransmitting 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 mapping of signal clusters 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 spatial streams. Transmit processor 416 then maps each spatial stream to subcarriers, multiplexes it 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.

[0234] 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 spatial stream destined for the second communication device 450. Symbols on each spatial 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 transmission from the first communication device 410 to the second communication device 450, the controller / processor 459 provides multiplexing, packet reassembly, decryption, header decompression, and control signal processing between the transport and logical channels to recover upper-layer data packets from the core network. The upper-layer data 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.

[0235] 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 transmission from the first communication device 410 to the second communication device 450, the controller / processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocation, implementing L2 layer functions for the user plane and control plane. The controller / processor 459 is also responsible for retransmitting 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 spatial 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.

[0236] 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. In the transmission from the second communication device 450 to the first communication device 410, the controller / processor 475 provides multiplexing between the transmission and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover upper-layer data packets from the UE 450. Upper-layer packets from the controller / processor 475 can be provided to the core network.

The frequency domain resources occupied by the first PUSCH belong to the target frequency domain resource pool. The first signaling is used to determine the frequency domain resources occupied by the first PUSCH from the target frequency domain resource pool. The first signaling is used to instruct at least one resource block interleaving. The frequency domain resources occupied by the first PUSCH are the intersection of the resource blocks included in the at least one resource block interleaving and the target frequency domain resource pool. The target frequency domain resource pool is one of multiple frequency domain resource pools. Among the multiple frequency domain resource pools, there are two mutually orthogonal frequency domain resource pools that are respectively associated with the CCE with the smallest index value occupied by the first PDCCH candidate and the CCE with the smallest index value. There is overlap between the CCEs with the smallest index value occupied by the second PDCCH candidate; the reference PDCCH candidate is one of the first PDCCH candidate or the second PDCCH candidate, and the reference PDCCH candidate is used to determine the target frequency domain resource pool from the plurality of frequency domain resource pools. The target frequency domain resource pool is the frequency domain resource pool with the smallest index value that intersects with the CCE with the smallest index value occupied by the reference PDCCH candidate among the plurality of frequency domain resource pools; the first PDCCH candidate and the second PDCCH candidate correspond to the first search space set and the second search space set, respectively. The first search space set and the second search space set have different search space set index values. The first search space set and the second search space set are both common search space sets (CSS sets); any one of the plurality of frequency domain resource pools is an uplink resource block set, and the first signaling is a DCI format 0_0 with CRC scrambled by an RNTI other than TC-RNTI.

Figure 9 As shown.

[0339] In Embodiment 9, the first signaling is used to instruct at least one resource block interleaving, and the frequency domain resources occupied by the first PUSCH are the intersection of the resource blocks included in the at least one resource block interleaving and the target frequency domain resource pool.

[0340] As an example, the first signaling is used to explicitly instruct the at least one resource block to interleave.

[0341] As an example, the first signaling is used to implicitly indicate that the at least one resource block is interleaved.

[0342] As one embodiment, the first signaling includes a first field, which is used to indicate the at least one resource block interleaving.

[0364] As an example, the at least one resource block interlacing is one or more resource block interlacings.

[0365] As an example, the statement that the intersection of the resource blocks included in the at least one resource block interleaving with the target frequency domain resource pool means that the intersection of all resource blocks included in the at least one resource block interleaving with the target frequency domain resource pool in the frequency domain.

[0366] As an example, the frequency domain resources occupied by the first PUSCH belong to both the at least one resource block interleaving and the target frequency domain resource pool.

[0423] In embodiment 12, the second transmitter 1201 transmits first information and first signaling. The first information is used to determine the correlation between the first PDCCH candidate and the second PDCCH candidate. Both the first PDCCH candidate and the second PDCCH candidate are used to carry the first signaling. The second receiver 1202 receives a first PUSCH. The frequency domain resources occupied by the first PUSCH belong to a target frequency domain resource pool. The first signaling is used to determine the frequency domain resources occupied by the first PUSCH from the target frequency domain resource pool. The target frequency domain resource pool is one of multiple frequency domain resource pools. Among the multiple frequency domain resource pools, there are two mutually orthogonal frequency domain resource pools that overlap with the CCE with the smallest index value occupied by the first PDCCH candidate and the CCE with the smallest index value occupied by the second PDCCH candidate, respectively. The reference PDCCH candidate is one of the first PDCCH candidate or the second PDCCH candidate. The reference PDCCH candidate is used to determine the target frequency domain resource pool from the multiple frequency domain resource pools.

[0424] As an example, the target frequency domain resource pool is the frequency domain resource pool with the smallest index value that intersects with the CCE with the smallest index value occupied by the reference PDCCH candidate among the plurality of frequency domain resource pools.

[0425] As one embodiment, the first PDCCH candidate and the second PDCCH candidate correspond to the first search space set and the second search space set, respectively, and the first search space set and the second search space set have different search space set index values.

[0426] As an example, the reference search space set is the search space set with the smaller search space set index value between the first search space set and the second search space set, and the reference PDCCH candidate is the PDCCH candidate corresponding to the reference search space set between the first PDCCH candidate and the second PDCCH candidate.

[0427] As an example, the first signaling is used to instruct at least one resource block interleaving, and the frequency domain resources occupied by the first PUSCH are the intersection of the resource blocks included in the at least one resource block interleaving and the target frequency domain resource pool.

[0428] As an example, any one of the multiple frequency domain resource pools is an uplink resource block set.

[0429] As an example, the first signaling is a DCI format 0_0 with the CRC scrambled by an RNTI other than TC-RNTI.
