Description

Method and device used in user equipment and base station for wireless communication

Technical Field

The present application relates to methods and apparatus in wireless communication systems, and more particularly, to methods and apparatus in wireless communication systems supporting multi-antenna transmission.

Background

Compared with the conventional 3GPP (3rd Generation Partner Project) LTE (Long-term Evolution) system, the 5G system can support more diverse application scenarios, such as eMBB (enhanced Mobile BroadBand), URLLC (Ultra-Reliable and low latency Communications, Ultra-high reliability and low latency Communications) and mtc (massive Machine-type Communications). Compared with other application scenarios, URLLC has higher requirements on transmission reliability, which is not only reflected on the physical layer shared channel, but also on the physical layer control channel. The 3GPP R (Release) 15 supports that different MCS (Modulation and Coding Scheme) tables and repeated transmission are used to improve the transmission reliability of the physical layer shared channel, and a higher AL (Aggregation Level) is used to improve the transmission reliability of the physical layer control channel. In R16, the transmission reliability of the physical layer shared channel and the control channel in URLLC scenario needs to be further enhanced.

Disclosure of Invention

The inventor finds, through research, that spatial transmit diversity (spatial diversity) based on multi-antenna/multi-TRP (Transmitter Receiver Point)/multi-panel technology is a potential solution for further improving the transmission reliability of the physical layer shared channel and the control channel in the URLLC scenario. The method carries out repeated transmission for a plurality of times on a TB (Transport Block) or a physical layer control signaling, and sends different repeated transmissions by using different antenna ports/beams/TRP/panel, thereby improving the transmission reliability by utilizing the space domain diversity gain. In this case, how to indicate TCI (Transmission Configuration Indication) states corresponding to different repeated transmissions is a problem to be solved. Considering that the load (payload) of the scheduling signaling cannot be too large in order to satisfy the transmission reliability of the physical layer control channel in the URLLC scenario, it is not desirable to indicate the corresponding TCI status for all repeated transmissions in the scheduling signaling. This problem is further complicated by the fact that the scheduling signaling of URLLC may itself be repeatedly transmitted by different antenna ports/beams/TRP/panel, whereas a UE (User Equipment) may only correctly receive a part of all the repeatedly transmitted scheduling signaling.

In view of the above, the present application discloses a solution. Without conflict, embodiments and features in embodiments in the user equipment of the present application may be applied to the base station and vice versa.

The method establishes the relation between the time-frequency resource occupied by each repeated transmission and the corresponding TCI state, or establishes the relation between the time-frequency resource occupied by the scheduling signaling and the TCI state corresponding to the repeated transmission, and indicates the TCI state corresponding to each repeated transmission in an implicit mode, thereby solving the problems.

Embodiment 3 illustrates a schematic diagram of an embodiment of radio protocol architecture for the user plane and the control plane, as shown in fig. 3.

Fig. 3 is a schematic diagram illustrating an embodiment of radio protocol architecture for the user plane and the control plane, fig. 3 showing the radio protocol architecture for the UE and the gNB 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 herein as PHY 301. Layer 2(L2 layer) 305 is above PHY301 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 (media 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-GW213 on the network side and an application layer that terminates at the other end of the connection (e.g., far end UE, 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 packets to reduce radio transmission overhead, security by ciphering the packets, and handover support for UEs between gnbs. The RLC sublayer 303 provides segmentation and reassembly of upper layer packets, retransmission of lost packets, and reordering of 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 one cell among the UEs. The MAC sublayer 302 is also responsible for HARQ operations. In the control plane, the radio protocol architecture for the UE and the gNB is substantially the same for the physical layer 301 and the L2 layer 305, but without the header compression function for the control plane. The Control plane also includes an RRC (Radio Resource Control) sublayer 306 in layer 3 (layer L3). The RRC sublayer 306 is responsible for obtaining radio resources (i.e., radio bearers) and configures the lower layers using RRC signaling between the gNB and the UE.

Example 4

Embodiment 4 illustrates a schematic diagram of an NR node and a UE as shown in fig. 4. Fig. 4 is a block diagram of a UE450 and a gNB410 in communication with each other in an access network.

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

The UE450 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.

In the DL (Downlink), at the gNB410, upper layer data packets from the core network are provided to a controller/processor 475. The controller/processor 475 implements the functionality of layer L2. In the DL, the controller/processor 475 provides header compression, ciphering, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the UE450 based on various priority metrics. Controller/processor 475 is also responsible for HARQ operations, retransmission of lost packets, and signaling to UE 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). The transmit processor 416 implements coding and interleaving to facilitate Forward Error Correction (FEC) at the UE450, as well as mapping of signal constellation 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. Transmit processor 416 then maps each spatial stream to subcarriers, multiplexes with reference signals (e.g., pilots) in the time and/or frequency domain, and then uses an Inverse Fast Fourier Transform (IFFT) to generate the physical channels carrying the time-domain multicarrier symbol streams. The multi-antenna transmit processor 471 then performs transmit analog precoding/beamforming operations on the time domain multi-carrier symbol stream. Each transmitter 418 converts the baseband multicarrier symbol stream provided by the multi-antenna transmit processor 471 into a radio frequency stream that is then provided to a different antenna 420.

In the DL (Downlink), at the UE450, each receiver 454 receives a signal through its respective antenna 452. Each receiver 454 recovers information modulated onto a radio frequency carrier and converts the radio frequency stream into a baseband multi-carrier symbol stream that is provided to a receive processor 456. Receive processor 456 and multi-antenna receive processor 458 implement the various signal processing functions of the L1 layer. A multi-antenna receive processor 458 performs receive analog precoding/beamforming operations on the baseband multi-carrier symbol stream from the receiver 454. Receive processor 456 converts the baseband multicarrier symbol stream after the receive analog precoding/beamforming operation from the time domain to the frequency domain using a Fast Fourier Transform (FFT). In the frequency domain, the physical layer data signals and the reference signals to be used for channel estimation are demultiplexed by the receive processor 456, and the data signals are subjected to multi-antenna detection in the multi-antenna receive processor 458 to recover any spatial streams destined for the UE 450. The symbols on each spatial stream are demodulated and recovered at a receive processor 456 and soft decisions are generated. Receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper layer data and control signals transmitted by the gNB410 on the physical channels. The upper layer data and control signals are then provided to a controller/processor 459. The controller/processor 459 implements the functionality of the L2 layer. The controller/processor 459 may be associated with a memory 460 that stores program codes and data. Memory 460 may be referred to as a computer-readable medium. In the DL, the controller/processor 459 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover upper layer data packets from the core network. The upper layer packet is then provided to all protocol layers above the L2 layer. Various control signals may also be provided to L3 for L3 processing. The controller/processor 459 is also responsible for error detection using an Acknowledgement (ACK) and/or Negative Acknowledgement (NACK) protocol to support HARQ operations.

In the UL (Uplink), at the UE450, a data source 467 is used to provide upper layer data packets to the controller/processor 459. Data source 467 represents all protocol layers above the L2 layer. Similar to the transmit function at the gNB410 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 gNB410, implementing L2 layer functions for the user plane and the control plane. The controller/processor 459 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the gNB 410. A transmit processor 468 performs modulation mapping, channel coding, and digital multi-antenna spatial precoding by a multi-antenna transmit processor 457 including codebook-based precoding and non-codebook based precoding, and beamforming, and the transmit processor 468 then modulates the resulting spatial streams into multi-carrier/single-carrier symbol streams, which are provided to different antennas 452 via a transmitter 454 after analog precoding/beamforming 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 provides the radio frequency symbol stream to the antenna 452.

In UL (Uplink), the function at the gNB410 is similar to the reception function at the UE450 described in DL. Each receiver 418 receives an rf signal through its respective antenna 420, converts the received rf signal to a baseband signal, and provides the baseband signal to a multi-antenna receive processor 472 and a receive processor 470. The receive processor 470 and the multiple antenna receive processor 472 collectively implement the functionality of the L1 layer. Controller/processor 475 implements the L2 layer functions. The controller/processor 475 can be associated with a memory 476 that stores program codes and data. Memory 476 may be referred to as a computer-readable medium. In the UL, the controller/processor 475 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover upper layer packets from the UE 450. Upper layer data packets from the controller/processor 475 may be provided to a core network. Controller/processor 475 is also responsible for error detection using the ACK and/or NACK protocol to support HARQ operations.
