Description

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

Technical Field

The present application relates to a method and apparatus in a wireless communication system, and more particularly, to a method and apparatus in a wireless communication system involving Cyclic Redundancy Check (CRC).

Background

CRC (Cyclic Redundancy Check) is a hash function that generates a short fixed bit Check code according to data such as network data packets or computer files, and is mainly used to detect or Check errors that may occur after data transmission or storage. It uses the principle of division and remainder to detect the error. In a conventional LTE (Long Term Evolution) system, CRC plays a specific role in error checking and identification of a target receiver.

In the 5G system, in order to meet different performance requirements set by diversified application scenarios, URLLC (Ultra-Reliable and Low Latency Communications) becomes one of three most main application scenarios of NR (New Radio) system. In URLLC, a typical application scenario is that the amount of information transmitted per time is small, and the requirements on transmission delay and transmission reliability are very high. According to the discussion of 3GPP (3rd Generation Partner Project) RAN (Radio Access Network) 1, URLLC transmission will support the use of retransmission to improve transmission reliability.

Disclosure of Invention

The inventor finds through research that in order to meet the requirement of URLLC on high reliability, the accuracy of error check on URLLC transmission must be high, and the error check accuracy provided by the maximum CRC bits supported by the current system cannot always meet the requirement of URLLC. Since the amount of information transmitted by URLLC at each time is usually small, the redundancy caused by further increasing the number of CRC bits will greatly reduce the transmission efficiency. How to improve the error checking accuracy of URLLC without adding extra redundancy is a problem to be solved.

In view of the above, the present application discloses a solution. It should be noted that although the initial motivation of the present application is for URLLC, the present application is also applicable to other traffic types and application scenarios. Without conflict, embodiments and features in embodiments in a first node of the present application may be applied to a second node and vice versa. The embodiments and features of the embodiments of the present application may be combined with each other arbitrarily without conflict.

The application discloses a method in a first node used for wireless communication, characterized by comprising:

sending a first wireless signal in a first time window, wherein the first time window is any one time window in M time windows, and the first wireless signal carries a first check bit block;

the information bit block corresponding to the first check bit block comprises a first bit block; the values of the bits comprised in the first block of parity bits are related to the positions of the first time window in the M time windows, or the number of bits comprised in the first block of parity bits is related to the positions of the first time window in the M time windows; the first block of bits is independent of a position of the first time window in the M time windows, M being a positive integer greater than 1.

As an embodiment, the problem to be solved by the present application is: how to improve the error checking accuracy of URLLC without increasing the number of CRC bits. The above method solves this problem by generating different blocks of check bits for the first block of bits in different ones of the M time windows.

As an embodiment, the method is characterized in that the first node transmits the wireless signal generated by the first bit block in each of the M time windows, but generates the check bit block of the first bit block with different CRC cyclic generation polynomials in different time windows. The above method has the advantage that the check bit blocks in different time windows can be jointly used for error checking of the first bit block, which corresponds to increasing the effective CRC bit number and improving the error checking precision of the first bit block. Meanwhile, the number of CRC bits actually transmitted is not increased, so that extra redundancy is avoided.

According to an aspect of the present application, the second wireless signal carries a second bit block and a third check bit block, the information bit block corresponding to the third check bit block includes the second bit block, and the first check bit block is independent of the second bit block.

According to one aspect of the application, the bit block of the first bit block after the first coding is used for generating the second wireless signal, and the code rate corresponding to the first coding is related to the position of the second time window in the M1 time windows.

As an embodiment, the above method has the advantage that the number of output bits of the first code is independent of the length of the check bit block of the first bit block in the second time window, so as to avoid the influence on resource allocation and resource mapping caused by adopting different check bit numbers in different time windows of the M time windows, and reduce implementation complexity.

As an embodiment, the above method has the advantage that the code rate of the channel coding is lower in the time windows with lower check bit number, so the wireless signals in these time windows have higher transmission reliability. The target recipient of the first wireless signal can accurately recover the first block of bits from the wireless signal received in these time windows, facilitating subsequent recovery of the block of check bits of the first block of bits, such as the first block of check bits.

According to one aspect of the present application, wherein the M1 is less than the M, the first node transmits the wireless signal carrying the first block of bits only in the M1 of the M time windows.

According to one aspect of the application, a first generator polynomial is used to generate the first block of check bits if the first time window is one of M2 time windows; if the first time window is one of M3 time windows, a second generator polynomial is used to generate the first block of check bits; the M2 time windows and the M3 time windows are two mutually exclusive subsets of the M time windows, the M2 and the M3 are positive integers less than the M, respectively.

As an example, the above method has the advantage that different CRC Cyclic Generator polynomials (Cyclic generators multinomials) are used in different ones of the M time windows to generate CRC bits, increasing the effective CRC length and improving the error checking accuracy for the first block of bits.

According to one aspect of the present application, the first check bit block comprises Q check bit sub-blocks, and the information bit block corresponding to each of the Q check bit sub-blocks comprises the first bit block; and Q is a positive integer.

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 (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-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.

gNB410 includes a controller/processor 475, a memory 476, a receive processor 470, a transmit processor 416, a channel encoder 477, a channel decoder 478, a transmitter/receiver 418, and an antenna 420.

The UE450 includes a controller/processor 459, memory 460, a data source 467, a transmit processor 468, a receive processor 456, a channel encoder 457, a channel decoder 458, a transmitter/receiver 454, and an antenna 452.

In the DL (Downlink), at the gNB, 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 allocation of radio resources for 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 channel encoder 477 perform various signal processing functions for the L1 layer (i.e., the physical layer). Channel encoder 477 performs coding and interleaving to facilitate Forward Error Correction (FEC) at UE 450. Transmit processor 416 performs mapping for 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)) and performs spatial precoding/beamforming on the encoded 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. Each transmitter 418 converts the baseband multi-carrier symbol stream provided by the transmit processor 416 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. The receive processor 456 and channel decoder 458 implement the various signal processing functions of the L1 layer. Receive processor 456 converts the baseband multicarrier symbol stream 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 physical layer data is recovered into spatial streams destined for the UE450 through multi-antenna detection in the receive processor 456. The symbols on each spatial stream are demodulated and recovered at a receive processor 456 and soft decisions are generated. Channel decoder 458 then decodes and deinterleaves the soft decisions to recover the upper layer data and control signals transmitted by the gNB410 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 can 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. The channel encoder 457 performs channel encoding and the encoded data is modulated into a multi-carrier/single-carrier symbol stream by modulation performed by the transmit processor 468 and multi-antenna spatial precoding/beamforming processing and provided to different antennas 452 via the transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by the transmit processor 468 into a radio frequency symbol stream that is provided 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 radio frequency signals through its respective antenna 420, converts the received radio frequency signals to baseband signals, and provides the baseband signals to a receive processor 470. Receive processor 470 and channel decoder 478 together implement the functions of layer L1. 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 packets from the controller/processor 475 may be provided to the core network. Controller/processor 475 is also responsible for error detection using the ACK and/or NACK protocol to support HARQ operations.
