Technical Field

The present application relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a transmission scheme and apparatus for random access in wireless communication.

Background

In the future, the application scenes of the wireless communication system are more and more diversified, and different application scenes put different performance requirements on the system. In order to meet different performance requirements of various application scenarios, research on New Radio interface (NR) technology (or fine Generation, 5G) is decided over 72 sessions of 3GPP (3rd Generation Partner Project) RAN (Radio Access Network), and standardization Work on NR is started over WI (Work Item) where NR passes through 75 sessions of 3GPP RAN.

In order to be able to adapt to various application scenarios and meet different requirements, research projects of Non-orthogonal Multiple Access (NoMA) under NR are also passed on 3GPP RAN #76 universal meeting, the research projects begin at Release 16, and WI is started to standardize related technologies after SI is over. As a bearing NoMA research project, WI of two-step random access (2-step RACH) under NR was also passed on 3GPP RAN #82 second congress.

Disclosure of Invention

The NR Release-16 system introduces a two-Step Random Access procedure (2-Step RACH) to meet the requirement of fast Access. MsgA (Message a) of the two-step random access procedure includes a random access preamble (PRACH preamble) and a physical uplink shared channel load (PUSCH payload); the random access preamble is sent on an RO (random access time), and the physical uplink shared channel load occupies a PRU (PUSCH Resource Unit) on a PO (PUSCH access time) to be sent. The random access preamble and the PRU in the message a are each independently configured, and a part of the random access preamble and a part of the PRU are invalid due to some resource collision. The association mapping between the random access preamble and the PRU in the message a is implicitly determined, resulting in that part of the random access preamble has no corresponding PRU association. When a random access preamble selected by User Equipment (UE) is mapped to a PRU, the UE sends a message 3 after receiving a fallback RAR, where the message 3 is actually a retransmission of a PUSCH payload in a message a; when the random access preamble selected by the user equipment is not mapped to the PRU, the user equipment sends a message 3 after receiving the fallback RAR, wherein the message 3 is the initial transmission of the PUSCH payload. The existing system does not effectively utilize the characteristic that the message 3 is the retransmission of the PUSCH payload in the message a, and the receiving accuracy of the PUSCH payload transmission in the message 3 cannot be utilized, so that the time delay of the two-step random access process is prolonged.

In view of the above problems, the present application discloses a method for interpreting a fallback RAR in a message B in a random access procedure, which can effectively utilize the characteristic that a message 3 is a retransmission of a PUSCH payload in a message a when a random access preamble selected by a UE is mapped to a PRU. It should be noted that, without conflict, the embodiments and features in the embodiments in the user equipment of the present application may be applied to the base station, and vice versa. The embodiments and features of the embodiments of the present application may be combined with each other arbitrarily without conflict. Further, although the original purpose of the present application is for random access, the present application can also be used for Beam Failure Recovery (Beam Failure Recovery).

Further, although the present application was originally directed to Uplink (Uplink), the present application can also be used with Sidelink (Sidelink). Further, although the present application was originally directed to single carrier communication, the present application can also be applied to multicarrier communication. Further, although the present application was originally directed to single antenna communication, the present application can also be applied to multi-antenna communication. Further, although the original intention of the present application is directed to the terminal and base station scenario, the present application is also applicable to the V2X scenario, the terminal and relay, and the relay and base station communication scenario, and achieves similar technical effects in the terminal and base station scenario. Furthermore, adopting a unified solution for different scenarios (including but not limited to V2X scenario and terminal to base station communication scenario) also helps to reduce hardware complexity and cost.

Example 4

Embodiment 4 shows a schematic diagram of a first communication device and a second communication device according to the present application, as shown in fig. 4. Fig. 4 is a block diagram of a first communication device 410 and a second communication device 450 communicating with each other in an access network.

The first communications device 410 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 second communications device 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.

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 the functionality of layer L2. In transmissions from the first communications device 410 to the first communications 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 communications device 450 based on various priority metrics. The controller/processor 475 is also responsible for 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). The transmit processor 416 implements coding and interleaving to facilitate Forward Error Correction (FEC) at the second communication device 450 and 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 a transmission from the first communications device 410 to the second communications device 450, at the second communications device 450, 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 second communication device 450. The symbols on each spatial stream are demodulated and recovered at a receive 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 first communications device 410 on the physical channel. 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 transmissions from the first communications device 410 to the second communications device 450, the controller/processor 459 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover upper layer 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.

In a transmission from the second communications device 450 to the first communications device 410, a data source 467 is used at the second communications device 450 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 first communications apparatus 410 described in the transmission from the first communications apparatus 410 to the second communications apparatus 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 retransmission of lost packets and signaling to said first communications device 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 a transmission from the second communication device 450 to the first communication device 410, the functionality at the first communication device 410 is similar to the receiving functionality 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 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 transmissions from the second communications device 450 to the first communications device 410, 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.
