Description

Method and apparatus in a node 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 wireless signals in a wireless communication system supporting a cellular network.

Background

In the 5G NR (New Radio, new air interface) system, eMBB (Enhance Mobile Broadband, enhanced mobile broadband), and URLLC (Ultra Reliable and Low Latency Communication, ultra high reliability and ultra low latency communication) are two major typical traffic types (SERVICE TYPE). In the 3GPP (3 rd Generation Partner Project, third generation partnership project) NR RELEASE release, DCI (Downlink Control Information ) signaling may indicate whether the scheduled traffic is Low Priority or High Priority; wherein, the high priority corresponds to URLLC traffic and the low priority corresponds to eMBB traffic.

In the discussion of the 3GPP NR Release 17 version, multiplexing (Multiplexing) of different services within a UE (User Equipment) is an important issue.

Disclosure of Invention

Multiplexing the high priority HARQ-ACK (HybridAutomatic RepeatreQuestACKnowledgement ) with the low priority HARQ-ACK into the same uplink physical channel (e.g., PUCCH) for transmission may improve overall transmission efficiency of the system, but may affect reporting performance of the high priority HARQ-ACK. How to optimize the transmission efficiency of the system on the premise of guaranteeing the reporting performance of the high priority HARQ-ACK is a key problem to be solved.

In view of the above, the present application discloses a solution.

Furthermore, the adoption of unified solutions for different scenarios (including but not limited to uplink, downlink, sidelink) also helps to reduce hardware complexity and cost. 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.

receiving first signaling and first DCI;

Transmitting at least the former of a first bit block including at least one HARQ-ACK information bit associated with the first DCI and a target bit block including at least one HARQ-ACK information bit not belonging to the first bit block;

The first DCI comprises a first domain, the value range of the first domain in the first DCI comprises a first value, a second value or a third value, the first value, the second value and the third value are mutually unequal in pairs; the value of the first field in the first DCI is used to determine whether to transmit the target bit block, and whether the first bit block and the target bit block are transmitted in the same physical channel or in different physical channels, respectively, when the target bit block is transmitted; when the value of the first field in the first DCI is equal to the first value, both the first bit block and the target bit block are transmitted in a third physical channel, the first DCI being used to determine the third physical channel; when the value of the first field in the first DCI is equal to the second value, the first bit block and the target bit block are transmitted in a first physical channel and a second physical channel, respectively, the first DCI is used to determine the first physical channel, the first signaling is used to determine the second physical channel, and the first physical channel and the second physical channel do not overlap in the time domain; when the value of the first field in the first DCI is equal to the third value, the target bit block is discarded from being transmitted.

As one embodiment, the problems to be solved by the present application include: and reasonably processing the low-priority HARQ-ACK information bits on the premise of ensuring the reporting performance of the high-priority HARQ-ACK.

As one embodiment, the problems to be solved by the present application include: how to determine the processing mode of the low priority HARQ-ACK information bits when PUCCHs of different priorities overlap in the time domain.

As one embodiment, the features of the above method include: the processing mode of the low priority HARQ-ACK information bit is determined according to the indication of one domain in the DCI.

As one embodiment, the features of the above method include: one field in the DCI is used to indicate whether to multiplex low-priority HARQ-ACK information bits and high-priority HARQ-ACK information bits into the same physical channel for transmission, to transmit the low-priority HARQ-ACK information bits and the high-priority HARQ-ACK information bits separately in different physical channels, or to discard the low-priority HARQ-ACK information bits.

Example 4

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

The first communication device 410 includes a controller/processor 475, a memory 476, a receive processor 470, a transmit processor 416, a multi-antenna receive processor 472, a multi-antenna transmit processor 471, a transmitter/receiver 418, and an antenna 420.

The second communication 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, upper layer data packets from the core network are provided to a controller/processor 475 at the first communication device 410. The controller/processor 475 implements the functionality of the L2 layer. In the transmission from the first communication device 410 to the second communication device 450, a controller/processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the second communication 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., physical layer). Transmit processor 416 performs coding and interleaving to facilitate Forward Error Correction (FEC) at the second communication device 450, 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 digitally space-precodes the coded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, 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 a transmission from the first communication device 410 to the second communication device 450, each receiver 454 receives a signal at the second communication device 450 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, wherein 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 stream destined for the second communication device 450. The symbols on each spatial stream are demodulated and recovered in a receive processor 456 and soft decisions are generated. A receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper layer data and control signals that were transmitted by the first communication device 410 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 the transmission from the first communication device 410 to the second communication device 450, the controller/processor 459 provides demultiplexing between transport and logical channels, packet reassembly, decryption, 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.

In the transmission from the second communication device 450 to the first communication device 410, a data source 467 is used at the second communication 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 functions at the first communication device 410 described in the transmission from the first communication device 410 to the second communication device 450, the controller/processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocations, implementing L2 layer functions for the user and control planes. The controller/processor 459 is also responsible for retransmission of lost packets and signaling to the first communication device 410. The transmit processor 468 performs modulation mapping, channel coding, and digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming, with the multi-antenna transmit processor 457 performing digital multi-antenna spatial precoding, after which the transmit processor 468 modulates 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 different 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 the transmission from the second communication device 450 to the first communication device 410, the function at the first communication device 410 is similar to the receiving function 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 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 transmission from the second communication device 450 to the first communication device 410, a controller/processor 475 provides demultiplexing between transport and logical channels, packet reassembly, decryption, 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.
