-The name of the invention of the original application: method and device used for wireless communication in user and base station

Technical Field

The present application relates to a method and apparatus for transmitting a wireless signal in a wireless communication system, and more particularly, to a method and apparatus for transmitting a wireless signal in a wireless communication system supporting multi-antenna transmission.

Background

Large scale (Massive) MIMO is one of the research hotspots for next generation mobile communications. In large-scale MIMO, multiple antennas are formed by beamforming, so that a narrower beam is formed to point to a specific direction, thereby improving communication quality. The beams formed by multi-antenna beamforming are generally relatively narrow and the beams of the base station and the user equipment need to be aligned for efficient communication. In order to ensure that the UE can receive or transmit data with the correct beam, according to the discussion of 3GPP (3 rd GenerationPartner Project, third generation partnership project) RAN1 (Radio Access Network ), the NR (new radio) system will support dynamic beam-related parameters indicating the UE (user equipment) and the data channel. How to carry this new added parameter in the most efficient way in dynamic scheduling signaling is a problem to be solved.

Disclosure of Invention

The inventors have found through research that dynamic indication of the beam of the data channel is not required at all times, and that in some cases the data channel may employ a default or preconfigured beam. These cases do not require beam-related parameters of the data channel to be carried in the dynamic scheduling signaling. But in order to reduce the complexity of blind detection of the user, the format of the scheduling signalling should remain consistent. When dynamic indication of the beam of the data channel is not needed, how to reasonably use the redundant bits in the scheduling signaling is a problem to be solved.

In view of the above, the present application discloses a solution. It should be noted that embodiments of the user equipment and features of embodiments of the present application may be applied to a base station and vice versa without conflict. The embodiments of the application and the features of the embodiments may be combined with each other arbitrarily without conflict.

Fig. 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for a user plane and a control plane, fig. 3 shows the radio protocol architecture for a UE and a gNB with 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 PHY301. Layer 2 (L2 layer) 305 is above PHY301 and is responsible for the link between the UE and the gNB through PHY301.

In DL (Downlink), at the gNB410, upper layer packets from the core network are provided to a controller/processor 475. The controller/processor 475 implements the functionality of the L2 layer. In DL, a controller/processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocations to UE450 based on various priority metrics. The controller/processor 475 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the UE 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for the L1 layer (i.e., physical layer). The transmit processor 416 performs coding and interleaving to facilitate Forward Error Correction (FEC) at the UE450, as well as 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-quadrature amplitude modulation (M-QAM). The multi-antenna transmit processor 471 performs digital spatial precoding/beamforming processing on the encoded and modulated symbols to generate one or more spatial streams. A transmit processor 416 then maps each spatial stream to a subcarrier, 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 a physical channel carrying the time domain multicarrier symbol stream. 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 multiple antenna transmit processor 471 to a radio frequency stream and then provides it to a different antenna 420.

In DL (Downlink), at the UE450, each receiver 454 receives signals 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 multicarrier symbol stream that is provided to a receive processor 456. The receive processor 456 and the multi-antenna receive processor 458 implement various signal processing functions for 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. The receive processor 456 converts the baseband multicarrier symbol stream after receiving the 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 signal and the reference signal are demultiplexed by the receive processor 456, where the reference signal is to be used for channel estimation, and the data signal is 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 in a receive processor 456 and soft decisions are generated. The soft decisions are then decoded and deinterleaved by a receive processor 456 to recover the upper layer data and control signals that were transmitted by the gNB410 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. Memory 460 may be referred to as a computer-readable medium. In 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 packets are 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 Acknowledgement (ACK) and/or Negative Acknowledgement (NACK) protocols to support HARQ operations.

In UL (Uplink), a data source 467 is used at the UE450 to provide upper layer data packets to a controller/processor 459. Data source 467 represents all protocol layers above the L2 layer. Similar to the transmit function at the gNB410 described in DL, the controller/processor 459 implements header compression, ciphering, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocations of the gNB410, implementing L2 layer functions for the user and control planes. The controller/processor 459 is also responsible for HARQ operations, retransmission of lost packets, and signaling to the gNB 410. The transmit processor 468 performs modulation mapping, channel coding, and digital multi-antenna spatial precoding/beamforming, with the multi-antenna transmit processor 457 then modulating the resulting spatial stream into a multi-carrier/single-carrier symbol stream, which is analog precoded/beamformed in the multi-antenna transmit processor 457 before being provided to the various antennas 452 via the transmitter 454. 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 it to an 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 radio frequency signals through its corresponding antenna 420, converts the received radio frequency signals to baseband signals, and provides the baseband signals to a multi-antenna receive processor 472 and a receive processor 470. The receive processor 470 and the multi-antenna receive processor 472 collectively implement the functions of the L1 layer. The controller/processor 475 implements L2 layer functions. The controller/processor 475 may 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 data packets from the UE 450. Upper layer packets from the controller/processor 475 may be provided to the core network. The controller/processor 475 is also responsible for error detection using an ACK and/or NACK protocol to support HARQ operations.
