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 Service types (Service Type). 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 (Downlink Control Information) signaling may indicate whether the scheduled traffic is Low Priority (Low Priority) or High Priority (High Priority), where the Low Priority corresponds to URLLC traffic and the 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, Multiplexing (Multiplexing) of different services in a UE (User Equipment) (Intra-UE) is a major point to be researched.

Disclosure of Invention

In the discussion of the NR URLLC project, the requirement of Reliability (Reliability) and Delay (Delay) for high-priority Data (Data) may be higher than that of low-priority UCI (Uplink Control Information) (e.g., low-priority HARQ-ACK (Hybrid Automatic Repeat reQuest Acknowledgement), and how to reasonably determine resource allocation between UCI and Data according to the relative relationship between the priority of UCI and the priority of PUSCH when UCI is multiplexed on a PUSCH (Physical Uplink Shared Channel) is a key problem to be solved.

In view of the above, the present application discloses a solution. In the above description of the problem, an Uplink (Uplink) is taken as an example; the present application is also applicable to Downlink (Downlink) transmission scenarios and Sidelink (Sidelink) transmission scenarios, and achieves similar technical effects in the uplink. Furthermore, employing a unified solution for different scenarios (including but not limited to uplink, downlink, companion link) also helps to reduce hardware complexity and cost. 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.

As an example, the terms in the present application are explained with reference to the definition of the specification protocol of IEEE (Institute of Electrical and Electronics Engineers).

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

receiving a first signaling and a second signaling;

sending a first signal in a first time-frequency resource block, wherein the first signal carries a first bit block group and a fourth bit block;

wherein the first signaling indicates the first time-frequency resource block; the first signaling comprises scheduling information of the first signal; the second signaling is used to determine a second block of bits; the first signal comprises a first sub-signal and a second sub-signal; the first sub-signal and the second sub-signal carry different bit blocks in the first bit block group respectively; the first sub-signal carries the fourth block of bits, the second block of bits being used to generate the fourth block of bits; the first signaling indicates a first target index, and the second signaling indicates a second target index; the first target index and the second target index are used together to determine whether the second sub-signal carries a block of bits generated by the second block of bits.

As an embodiment, the problem to be solved by the present application includes: when UCI is multiplexed onto one PUSCH, how to reasonably determine transmission resources allocated to the UCI according to a relative relationship between the priority of the UCI and the priority of the one PUSCH.

As an embodiment, the essence of the above method is: when UCI is multiplexed onto one PUSCH, a priority of the UCI and a priority of the one PUSCH are used in common to determine a transmission resource allocated to the UCI.

As an example, the above method has the benefits of: the multiplexing of the services with different priorities is allowed, and the problem that the overall efficiency of the system is reduced because low-priority HARQ-ACK is directly discarded when the services with different priorities collide is solved.

As an example, the above method has the benefits of: when the low priority control information is multiplexed onto the high priority shared channel/data channel, less transmission resources are allocated to the transmission of the low priority control information, reducing the impact of the multiplexing of the low priority control information on the high priority transmission.

As an embodiment, the essence of the above method is: when a low priority UCI is multiplexed onto a high priority PUSCH used for transmission of two TBs, the low priority UCI is multiplexed onto a transmission layer occupied by only one of the two TBs; when a high priority UCI is multiplexed onto an arbitrary priority PUSCH used for transmission of two TBs, the high priority UCI is multiplexed onto all transmission layers in the arbitrary priority PUSCH; when a low priority UCI is multiplexed onto a low priority PUSCH used for transmission of two TBs, the low priority UCI is multiplexed onto all transmission layers in the low priority PUSCH.

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 first and second communication node devices and the two UEs through PHY 301. 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 second communication node device. The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides security by ciphering data packets and provides handoff support between second communication node devices to the first communication node device. 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. The MAC sublayer 302 provides multiplexing between logical and transport channels.

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. Upper layer data packets from the controller/processor 475 may be provided to a core network.
