[0003] --Application number of the original application: 201810200891.3

[0004] --Title of the invention in the original application: A method and apparatus for user equipment and base station used for wireless communication Technical Field

[0005] The present application relates to a method and a device in a wireless communication system, and more particularly to a method and a device in a wireless communication system supporting multi-antenna transmission. Background Art

[0006] Massive MIMO has become a research hotspot for the next generation of mobile communications. In massive MIMO, multiple antennas form narrow beams pointing in a specific direction through beamforming to improve communication quality. The beams formed by multi-antenna beamforming are generally narrow, and the beams of the base station and UE (User Equipment) need to be aligned for effective communication. When the beams of the base station and UE are out of sync due to obstruction or UE movement, that is, when they are not aligned, the communication quality between the two parties will be greatly reduced or even unable to communicate.

[0007] In order to improve the robustness of communication and the transmission rate of a single UE, multiple TRPs (Transmitter Receiver Points) can serve a UE at the same time. The UE uses different beams to align beams from different TRPs to form multiple beam pairs. Multiple beam pairs can transmit the same data to improve the communication reliability of the UE, or transmit different data to improve the throughput of the UE. Summary of the invention

[0008] The inventors have found through research that when multiple TRPs serve one UE at the same time, uplink transmissions for multiple TRPs need to be sent with the correct beamforming vector to ensure that they can be correctly received by the corresponding TRPs. When uplink data and uplink control information for different TRPs conflict in the time domain, whether the uplink control information for another TRP can be carried on the physical layer data channel for one TRP needs to be determined based on the transmission beams for the two TRPs; otherwise, the reception of the uplink control information will fail, or additional delays will be caused because the uplink control information needs to be passed from one TRP to another TRP.

[0009] In view of the above problems, the present application discloses a solution. It should be noted that although the original motivation of the present application is for multi-TRP transmission, the present application is also applicable to the scenario of single TRP transmission. In the absence of conflict, the embodiments and features in the user equipment of the present application can be applied to the base station, and vice versa. In the absence of conflict, the embodiments and features in the embodiments of the present application can be arbitrarily combined with each other.

[0010] The present application discloses a method in a user equipment used for wireless communication, characterized by comprising:

[0013] The first signaling and the second signaling are used to determine the first antenna port group and the second antenna port group, respectively; the first antenna port group and the second antenna port group are applicable to the first time-frequency resource and the second time-frequency resource, respectively; an antenna port group includes a positive integer number of antenna ports; at least one of the following is used to determine the target time-frequency resource from the first time-frequency resource and the second time-frequency resource:

The advantage of this method is that it avoids sending control information for another TRP with a beam for one TRP, ensuring that the uplink control information can always be correctly received by its target receiver.

[0021] As an embodiment, the advantage of the above method is that the correct beam is always used to send the first reporting information, which ensures the transmission reliability of the first reporting information and avoids additional delays.

[0214] Example 3

[0215] Embodiment 3 illustrates a schematic diagram of an embodiment of a wireless protocol architecture of a user plane and a control plane, as shown in the attached figure. Figure 3 shown.

[0216] Attached Figure 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane and a control plane, Figure 3The radio protocol architecture for the UE and gNB is shown in 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 as PHY 301 herein. Layer 2 (L2 layer) 305 is above PHY 301 and is responsible for the link between the UE and the gNB through PHY 301. In the user plane, the 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 gNB on the network side. Although not shown, the UE may have several protocol layers above the L2 layer 305, including a network layer (e.g., IP layer) that terminates at the P-GW 213 on the network side and an application layer that terminates at the other end of the connection (e.g., a remote UE, a server, etc.). The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides header compression for upper layer data packets to reduce radio transmission overhead, provides security by encrypting data packets, and provides handover support for UEs between gNBs. 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 (Hybrid Automatic Repeat reQuest). 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 UEs. The MAC sublayer 302 is also responsible for HARQ operations. In the control plane, the radio protocol architecture for UEs and gNBs is substantially the same for PHY301 and L2 layer 305, but there is no header compression function for the control plane. The control plane also includes an RRC (Radio Resource Control) sublayer 306 in Layer 3 (L3 layer). The RRC sublayer 306 is responsible for obtaining radio resources (ie, radio bearers) and configuring lower layers using RRC signaling between the gNB and the UE.

[0233] Example 4

[0234] Embodiment 4 illustrates a schematic diagram of an NR node and a UE, as shown in the attached Figure 4 Attached Figure 4 is a block diagram of UE450 and gNB410 communicating with each other in an access network.

[0235] gNB410 includes a controller / processor 475, a memory 476, a receive processor 470, a transmit processor 416, a multi-antenna receive processor 472, a multi-antenna transmit processor 471, a transmitter / receiver 418 and an antenna 420.

[0236] UE 450 includes a controller / processor 459 , a memory 460 , a data source 467 , a transmit processor 468 , a receive processor 456 , a multi-antenna transmit processor 457 , a multi-antenna receive processor 458 , a transmitter / receiver 454 , and an antenna 452 .

[0237] In DL (Downlink), at gNB410, upper layer data packets from the core network are provided to the controller / processor 475. The controller / processor 475 implements the functionality of the L2 layer. In DL, the controller / processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to UE450 based on various priority metrics. The controller / processor 475 is also responsible for HARQ operations, retransmission of lost packets, and signaling to UE450. 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). The transmit processor 416 implements coding and interleaving to facilitate forward error correction (FEC) at the UE450, as well as mapping of signal constellations based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-phase shift keying (M-PSK), M-quadrature amplitude modulation (M-QAM)). The multi-antenna transmit processor 471 performs digital spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing on the coded and modulated symbols to generate one or more spatial streams. The transmit processor 416 then maps each spatial stream to a subcarrier, multiplexes it with a reference signal (e.g., a pilot) in the time domain and / or frequency domain, and then uses an inverse fast Fourier transform (IFFT) to generate a physical channel carrying a time-domain multi-carrier symbol stream. The multi-antenna transmit processor 471 then performs a transmit analog precoding / beamforming operation on the time-domain multi-carrier symbol stream. Each transmitter 418 converts the baseband multi-carrier symbol stream provided by the multi-antenna transmit processor 471 into a radio frequency stream, which is then provided to different antennas 420.

[0238] In DL (Downlink), at UE450, each receiver 454 receives a signal through its corresponding antenna 452. Each receiver 454 recovers the information modulated onto the RF carrier and converts the RF stream into a baseband multi-carrier symbol stream and provides it to the receiving processor 456. The receiving processor 456 and the multi-antenna receiving processor 458 implement various signal processing functions of the L1 layer. The multi-antenna receiving processor 458 performs a receiving analog precoding / beamforming operation on the baseband multi-carrier symbol stream from the receiver 454. The receiving processor 456 uses a fast Fourier transform (FFT) to convert the baseband multi-carrier symbol stream after the receiving analog precoding / beamforming operation 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 receiving processor 456, where the reference signal will be used for channel estimation, and the data signal is recovered after multi-antenna detection in the multi-antenna receiving processor 458 to any spatial stream destined for UE450. The symbols on each spatial stream are demodulated and recovered in the receiving processor 456, and soft decisions are generated. The receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper layer data and control signals transmitted by the gNB 410 on 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 the L2 layer. The controller / processor 459 may be associated with a memory 460 that stores program codes and data. The memory 460 may be referred to as a computer-readable medium. In the DL, the controller / processor 459 provides multiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover upper layer data packets from the core network. The upper layer data packets are then provided to all protocol layers above the L2 layer. Various control signals may also be provided to the L3 for L3 processing. The controller / processor 459 is also responsible for error detection using an acknowledgment (ACK) and / or negative acknowledgment (NACK) protocol to support HARQ operations.

[0239] In UL (Uplink), at UE450, data source 467 is used to provide upper layer data packets to controller / processor 459. Data source 467 represents all protocol layers above the L2 layer. Similar to the transmission function at gNB410 described in DL, 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 gNB410, and implements L2 layer functions for user plane and control plane. Controller / processor 459 is also responsible for HARQ operations, retransmission of lost packets, and signaling to gNB410. The transmit processor 468 performs modulation mapping and channel coding processing, and the multi-antenna transmit processor 457 performs digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming processing. Then, the transmit processor 468 modulates the generated spatial stream into a multi-carrier / single-carrier symbol stream, which is then provided to different antennas 452 via the transmitter 454 after analog precoding / beamforming operations in the multi-antenna transmit processor 457. Each transmitter 454 first converts the baseband symbol stream provided by the multi-antenna transmit processor 457 into a radio frequency symbol stream, and then provides it to the antenna 452.

[0240] In the UL (Uplink), the functions at the gNB 410 are similar to the receiving functions at the UE 450 described in the DL. Each receiver 418 receives a radio frequency signal through its corresponding antenna 420, converts the received radio frequency signal into a baseband signal, and provides the baseband signal to the multi-antenna receive processor 472 and the receive processor 470. The receive processor 470 and the multi-antenna receive processor 472 jointly implement the functions of the L1 layer. The controller / processor 475 implements the L2 layer functions. The controller / processor 475 may be associated with a memory 476 storing program codes and data. The memory 476 may be referred to as a computer-readable medium. In the UL, the controller / processor 475 provides multiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover upper layer data packets from the UE 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 operations.

The beamforming vector corresponding to one antenna port in the antenna port group #0 is obtained by the product of the analog beamforming vector #0 and the digital beamforming vector #0. The beamforming vector corresponding to an antenna port in the antenna port group #1 is obtained by multiplying the analog beamforming matrix formed by diagonally arranging the analog beamforming vector #1 and the analog beamforming vector #2 and the digital beamforming vector #1.
