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, the multiplexing of different priority services in UE (User Equipment) is a major point to be researched.

Disclosure of Invention

In order to support Multiplexing (Multiplexing) of services with different priorities in a UE, how to multiplex UCI (Uplink Control Information) onto a PUSCH when there is a Collision (Collision) on a time domain in a PUSCH (Physical Uplink Shared CHannel) and a PUCCH (Physical Uplink Control CHannel) with different priorities 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, the uplink is taken as an example; the present application is also applicable to a downlink transmission scenario and a Sidelink (Sidelink) transmission scenario, 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.

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 first signaling and a second signaling, wherein the first signaling and the second signaling are respectively used for determining a first air interface resource block and a second air interface resource block;

transmitting a target signal in a target air interface resource block;

the first air interface resource block is reserved for transmission of a first bit block, the second air interface resource block is reserved for transmission of a second bit block, and time domain resources occupied by the first air interface resource block and time domain resources occupied by the second air interface resource block are overlapped; the first bit block is used to generate the target signal; the target air interface resource block is the first air interface resource block, or the target air interface resource block is the second air interface resource block; the ending time of the first air interface resource block in the time domain is a first time, and the number of bits included in the first bit block is used for determining a second time; the second time is not earlier in time domain than the first time; a time interval between the second time instant and the first time instant is used to determine whether a bit in the second block of bits is used to generate the target signal; the first bit block and the second bit block correspond to different types, respectively.

As an embodiment, the problem to be solved by the present application includes: how to reasonably multiplex high priority UCI onto low priority PUSCH when high priority PUCCH and low priority PUSCH overlap in time domain.

As an embodiment, the problem to be solved by the present application includes: how to optimize (Optimization) the uplink transmission of the UE under the constraint of satisfying the Delay (Delay) requirement of high priority information when dealing with the transmission collision of information of different priorities.

As an embodiment, the essence of the above method is that when the high priority PUCCH and the low priority PUSCH overlap in the time domain: if the high-priority UCI is multiplexed on the low-priority PUSCH for transmission without extra time delay, the UE judges that the high-priority UCI is multiplexed on the low-priority PUSCH for transmission; otherwise, the UE judges that the high-priority UCI is transmitted on the high-priority PUCCH.

As an embodiment, the essence of the above method is that when the high priority PUCCH and the low priority PUSCH overlap in the time domain: if the extra time delay generated by multiplexing the high-priority UCI to the low-priority PUSCH for transmission is within an acceptable range, the UE judges that the high-priority UCI is multiplexed to the low-priority PUSCH for transmission; otherwise, the UE judges that the high-priority UCI is transmitted on the high-priority PUCCH.

As an embodiment, the essence of the above method is that when the high priority channel and the low priority channel overlap in the time domain: if the extra time delay generated by multiplexing the high-priority information to the low-priority channel for transmission is within an acceptable range, the UE judges that the high-priority information is multiplexed to the low-priority channel for transmission; otherwise, the UE judges that the high-priority information is transmitted on the high-priority channel, and the UE judges that the low-priority information is discarded.

As an embodiment, the essence of the above method is that when the high priority channel and the low priority channel overlap in the time domain: if the high-priority information is multiplexed on the low-priority channel for transmission without extra time delay, the UE judges that the high-priority information is multiplexed on the low-priority channel for transmission; otherwise, the UE judges that the high-priority information is transmitted on the high-priority channel, and the UE judges that the low-priority information is discarded.

As an example, the above approach has the benefit of guaranteeing latency requirements for high priority control information (e.g., UCI).

As an embodiment, the above method has a benefit that low priority traffic data/control information is also transmitted on the low priority channel on condition that the latency requirement of high priority control information (e.g., UCI) is met; the above approach improves transmission efficiency compared to directly dropping (Drop) low priority traffic data/control information.

According to one aspect of the application, the above method is characterized in that,

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 that carry 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. The data source 467 represents all protocol layers above the L2 layer. Similar to the send 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 performs header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocation, performing 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 rf signals through its respective antenna 420, converts the received rf 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 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.
