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 over the 3GPP RAN symposium. Among them, Multiplexing (Multiplexing) of different services in a UE (User Equipment) (Intra-UE) is a major point to be researched.

Disclosure of Invention

After introducing multiplexing of different priority services in the UE, the UE may multiplex the low priority UCI onto a high priority PUCCH (Physical Uplink Control CHannel) for transmission. How to reasonably multiplex the high priority information under the condition of guaranteeing reliability (reliability) or delay (delay) requirements to improve the system performance 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 (SL) transmission scenarios, and achieves similar technical effects in 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.

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

receiving a second signaling and a first signaling;

sending a first signal in a first air interface resource block, wherein the first signal carries a first bit block;

wherein the first signaling and the second signaling are used to determine the first bit block and the second bit block, respectively; the first signaling is used to determine the first resource block of the air interface; the first bit block comprises a first type of HARQ-ACK, and the second bit block comprises a second type of HARQ-ACK; the first type of HARQ-ACK and the second type of HARQ-ACK are different types of HARQ-ACK respectively; the first bit block and the second bit block respectively correspond to different indexes; the first signaling comprises a second domain; the second field in the first signaling is used to determine the number of bits carried by the first signal that relate to the second block of bits.

As an embodiment, the problem to be solved by the present application includes: when a plurality of PUCCHs carrying UCIs with different priorities collide, how to determine whether the UCIs with different priorities are multiplexed into the same PUCCH is a problem.

As an embodiment, the problem to be solved by the present application includes: when a plurality of PUCCHs carrying UCIs with different priorities collide, how to determine the multiplexing modes of the UCIs with different priorities.

As an embodiment, the essence of the above method is: when a plurality of PUCCHs carrying UCIs with different priorities collide, one domain included in DCI corresponding to a high-priority HARQ (Hybrid Automatic Repeat reQuest Acknowledgement) dynamically indicates whether the low-priority UCI is multiplexed to the high-priority PUCCH.

As an embodiment, the essence of the above method is: the base station may dynamically instruct the UE to multiplex low priority UCI into the high priority PUCCH for transmission or to drop transmission of low priority UCI according to the high priority information for reliability or latency requirements.

As an example, the above method has the benefits of: the base station can perform dynamic (dynamic) indication on the reliability or delay requirement according to the high-priority information, and the optimization of the overall performance of the system is facilitated.

As an embodiment, the essence of the above method is: when a plurality of PUCCHs carrying UCIs with different priorities collide, one domain included in DCI corresponding to the high-priority HARQ dynamically indicates the number of bits of the low-priority UCI multiplexed into the high-priority PUCCH.

As an example, the above method has the benefits of: the influence on the transmission performance (including the performance such as reliability or time delay) of the high-priority UCI caused by multiplexing among the UCIs with different priorities is reduced.

a third air interface resource block is reserved for the first bit block; a second air interface resource block is reserved for the second bit block; and the third air interface resource block and the second air interface resource block are overlapped in a time domain.

the second field in the first signaling is used for determining whether a bit block generated by the second bit block is used for determining a first air interface resource block set; the first air interface resource block is one air interface resource block in the first air interface resource block set.

As an example, the above method has the benefits of: the base station can dynamically indicate whether the resources reserved for the high-priority UCI are used for transmitting the low-priority UCI or not, and the optimization of resource allocation is facilitated.

said number of bits carried by said first signal relating to said second block of bits is equal to one of K candidate numbers; the second field in the first signaling indicates an index of the number of bits carried by the first signal relating to the second block of bits among the K candidate numbers; the K is greater than 1.

when the value of the second field in the first signaling is equal to a first numerical value, the second field in the first signaling indicates that the number of bits carried by the first signal related to the second block of bits is equal to zero; when the value of the second field in the first signaling is equal to a second numerical value, the second field in the first signaling indicates that the number of bits carried by the first signal relating to the second block of bits is not greater than a seventh number; the second field in the first signaling indicates that the number of bits carried by the first signal related to the second block of bits is equal to a total number of bits comprised by the second block of bits when a value of the second field in the first signaling is equal to a third value.

the second field in the first signaling is used to determine whether the size of the first block of bits is used to determine the number of bits carried by the first signal that relate to the second block of bits.

As an embodiment, the essence of the above method is: the UE determines the number of bits of the second type of HARQ-ACK (low priority HARQ-ACK) to be transmitted based on the indication of the second field in the first signaling and the size of the first block of bits.

As an example, the above method has the benefits of: excessive use of high priority resources for transmission of priority information is avoided.

the second field in the first signaling is used to determine whether the number of bits of the second type of HARQ-ACK related to the second bit block carried by the first signal is greater than zero; the first signaling comprises a third domain; the first signal carries the second type of HARQ-ACK independent of the second bit block when the value of the second field in the first signaling is equal to a sixth numerical value and the value of the third field in the first signaling is equal to a seventh numerical value; when the value of the second field in the first signaling is not equal to the sixth numerical value or the value of the third field in the first signaling is not equal to the seventh numerical value, the first signal does not carry the second type of HARQ-ACK independent of the second bit block.

As an embodiment, the essence of the above method is: the base station dynamically instructs the UE to report HARQ-ACK information for which priorities and which PDSCH groups (PDSCH groups).

As an example, the above method has the benefits of: the method can carry out HARQ-ACK reporting more flexibly and reduce unnecessary resource overhead.

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 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.
