Description

Method and apparatus in a node used for wireless communication

Technical Field

The present application relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a transmission method and apparatus for a wireless signal in a wireless communication system supporting a cellular network.

Background

In the 5G system, eMBB (enhanced Mobile Broadband), and URLLC (Ultra Reliable and Low Latency Communication) are two typical traffic types. In 3GPP (3rd Generation Partner Project, third Generation partnership Project) NR (New Radio, New air interface) Release 15, a New Modulation and Coding Scheme (MCS) table is defined for the requirement of lower target BLER (10^ -5) of URLLC service. In order to support the higher required URLLC traffic, such as higher reliability (e.g. target BLER is 10^ -6), lower delay (e.g. 0.5-1ms), etc., in 3GPP NR Release 16, DCI signaling may indicate whether the scheduled PDSCH is Low Priority (Low Priority) or High Priority (High Priority), where Low Priority corresponds to URLLC traffic and High Priority corresponds to eMBB traffic. When a low priority transmission overlaps a high priority transmission in the time domain, the high priority transmission is performed and the low priority transmission is discarded.

The URLLC enhanced WI (Work Item) by NR Release 17 was passed on the 3GPP RAN #86 second-time congregation. Among them, the multiplexing of different priority services in UE (User Equipment) is a major point to be researched.

To better support the transmission of traffic of different priorities, the counter DAI needs to be reconsidered.

As an embodiment, the problem to be solved by the present application is: when two different types of HARQ codebooks are transmitted on the same CHannel (e.g., Physical Uplink Control CHannel (PUCCH)), the counter DAI needs to be reconsidered in order to improve the efficiency of HARQ feedback and avoid inconsistency of understanding of the HARQ feedback codebooks by both communication parties.

As an embodiment, the above method has a benefit in mitigating the impact of the loss of lower priority DCI on higher priority HARQ information feedback when different types of HARQ codebooks are allowed to be transmitted on the same channel (e.g., PUCCH).

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 afirst communication device 410 and asecond communication device 450 communicating with each other in an access network.

Thefirst communications device 410 includes a controller/processor 475, amemory 476, a receiveprocessor 470, a transmitprocessor 416, a multiple antenna receiveprocessor 472, a multiple antenna transmitprocessor 471, a transmitter/receiver 418, and anantenna 420.

Thesecond communications device 450 includes a controller/processor 459, amemory 460, adata source 467, a transmitprocessor 468, a receiveprocessor 456, a multi-antenna transmitprocessor 457, a multi-antenna receiveprocessor 458, a transmitter/receiver 454, and anantenna 452.

In the transmission from thefirst communication device 410 to thesecond communication device 450, at thefirst 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 thefirst communications device 410 to thefirst 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 thesecond communications device 450 based on various priority metrics. The controller/processor 475 is also responsible for retransmission of lost packets and signaling to thesecond communication device 450. The transmitprocessor 416 and the multi-antenna transmitprocessor 471 implement various signal processing functions for the L1 layer (i.e., the physical layer). The transmitprocessor 416 implements coding and interleaving to facilitate Forward Error Correction (FEC) at thesecond 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 transmitprocessor 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. Transmitprocessor 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 transmitprocessor 471 then performs transmit analog precoding/beamforming operations on the time domain multi-carrier symbol stream. Eachtransmitter 418 converts the baseband multicarrier symbol stream provided by the multi-antenna transmitprocessor 471 into a radio frequency stream that is then provided to adifferent antenna 420.

In a transmission from thefirst communications device 410 to thesecond communications device 450, at thesecond communications device 450, eachreceiver 454 receives a signal through itsrespective antenna 452. Eachreceiver 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 receiveprocessor 456. Receiveprocessor 456 and multi-antenna receiveprocessor 458 implement the various signal processing functions of the L1 layer. A multi-antenna receiveprocessor 458 performs receive analog precoding/beamforming operations on the baseband multi-carrier symbol stream from thereceiver 454. Receiveprocessor 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 receiveprocessor 456, and the data signals are subjected to multi-antenna detection in the multi-antenna receiveprocessor 458 to recover any spatial streams destined for thesecond communication device 450. The symbols on each spatial stream are demodulated and recovered at a receiveprocessor 456 and soft decisions are generated. The receiveprocessor 456 then decodes and deinterleaves the soft decisions to recover the upper layer data and control signals transmitted by thefirst 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 amemory 460 that stores program codes and data.Memory 460 may be referred to as a computer-readable medium. In transmissions from thefirst communications device 410 to thesecond 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 thesecond communications device 450 to thefirst communications device 410, adata source 467 is used at thesecond 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 thefirst communications apparatus 410 described in the transmission from thefirst communications apparatus 410 to thesecond 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 saidfirst communications device 410. A transmitprocessor 468 performs modulation mapping, channel coding, and digital multi-antenna spatial precoding by a multi-antenna transmitprocessor 457 including codebook-based precoding and non-codebook based precoding, and beamforming, and the transmitprocessor 468 then modulates the resulting spatial streams into multi-carrier/single-carrier symbol streams, which are provided todifferent antennas 452 via atransmitter 454 after analog precoding/beamforming in the multi-antenna transmitprocessor 457. Eachtransmitter 454 first converts the baseband symbol stream provided by the multi-antenna transmitprocessor 457 into a radio frequency symbol stream and provides the radio frequency symbol stream to theantenna 452.

In a transmission from thesecond communication device 450 to thefirst communication device 410, the functionality at thefirst communication device 410 is similar to the receiving functionality at thesecond communication device 450 described in the transmission from thefirst communication device 410 to thesecond communication device 450. Eachreceiver 418 receives rf signals through itsrespective antenna 420, converts the received rf signals to baseband signals, and provides the baseband signals to a multi-antenna receiveprocessor 472 and a receiveprocessor 470. The receiveprocessor 470 and the multiple antenna receiveprocessor 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 amemory 476 that stores program codes and data.Memory 476 may be referred to as a computer-readable medium. In transmissions from thesecond communications device 450 to thefirst 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 theUE 450.
