Description

Method and device used in wireless communication node

Technical Field

The present invention relates to a transmission method and apparatus in a wireless communication system, and more particularly, to a communication method and apparatus performed on a Sidelink (Sidelink) in wireless communication.

Background

In the future, the application scenes of the wireless communication system are more and more diversified, and different application scenes put different performance requirements on the system. In order to meet different performance requirements of various application scenarios, research on New air interface technology (NR) or Fifth Generation 5G is decided over 72 sessions of 3GPP (3 rd Generation Partner Project) RAN (Radio Access Network), and standardization of NR is started over 3GPP RAN #75 sessions over WI (Work Item) where NR passes.

For the rapidly developing Vehicle-to-evolution (V2X) services, the 3GPP also started standard development and research work under the NR framework. Currently, 3GPP has completed the work of formulating the requirements for the service of 5G V2X and has written the standard TS 22.886. The 3GPP defines a 4-large application scenario Group (Use Case Group) for the 5G V2X service, including: automatic queuing Driving (Vehicles platform), extended sensing (Extended Sensors), semi/full automatic Driving (Advanced Driving) and Remote Driving (Remote Driving). NR-based V2X technical studies have been initiated on the 3GPP ran #80 event.

Disclosure of Invention

In order to meet new service requirements, compared with the LTE V2X system, the NR V2X system has the key technical features of higher throughput, higher reliability, lower delay, longer transmission distance, more accurate positioning, stronger variability of packet size and transmission period, and more effective coexistence with existing 3GPP technology and non-3 GPP technology. The current mode of operation of LTE V2X systems is limited to Broadcast (Broadcast) transmissions only. According to the consensus reached in the 3GPP RAN #80 congress, NR V2X will study technical solutions supporting Unicast (Unicast), multicast (Groupcast) and broadcast multiple working modes.

In the current LTE D2D (Device to Device)/V2X operation mode, the wireless signals transmitted by the ue through the Sidelink are broadcast and are not transmitted to a specific ue. When a large data packet service exists for a certain specific user equipment, the resource utilization efficiency is very low through the working mode of broadcast transmission, and reliable transmission cannot be guaranteed; D2D and V2X in the NR context are therefore required to consider unicast transmission to improve spectral efficiency and transmission performance.

In view of the above, the present application discloses a solution to support unicast transmission. 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. Further, although the present application was originally directed to unicast-based transmission mechanisms, the present application can also be used for broadcast and multicast transmissions. Further, although the present application is intended for single carrier communication, the present application can also be used for multicarrier communication.

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

receiving K first-type wireless signals, wherein K is a positive integer;

sending a first signaling;

wherein the first signaling is used to indicate whether the K first type wireless signals are correctly received; whether the first signaling comprises target configuration information related to the value of K or whether the first signaling comprises the target configuration information related to channel coding results for the K first-class wireless signals; the target configuration information is used for scheduling target wireless signals for a target terminal, the senders of the K first-class wireless signals are K terminals respectively, and at least one terminal of the K terminals is non-co-located with the target terminal.

As an example, the above method has the benefits of: when the first node performs sidelink communication with the K terminals at the same time and there is a collision in the sending of the K HARQ-ACK (Hybrid Automatic Repeat reQuest acknowledgement) information for the K terminals, the above scheme can ensure that the K HARQ-ACK information is all sent out under higher spectrum efficiency.

As an embodiment, the above method is characterized in that: when the value of K is small or the K first-type wireless signals are all correctly received, the K HARQ-ACK Information can be sent to the K terminals by using fewer bits, and then the first node directly sends the K HARQ-ACK Information by using a Sidelink Control Information (SCI) including scheduling Information; when the value of K is large, or the K first-class wireless signals are not all correctly received, and the first node needs to distinguish HARQ-ACKs targeted by the first-class wireless signals from different terminals, the first node can only send the K HARQ-ACK information by using the SCI which specially sends the K HARQ-ACK information and does not contain scheduling information; in this way, the first node dynamically selects the format used by the first signaling, thereby avoiding the problem of too large overhead of control signaling caused by too many air interface resources occupied by the first signaling.

According to one aspect of the application, the above method is characterized by comprising:

receiving K first-class signaling, wherein the K first-class signaling respectively indicates K first-class air interface resources;

wherein the K first type of air interface resources are reserved for K HARQ-ACKs, respectively, and the K HARQ-ACKs are associated with the K first type of wireless signals, respectively.

As an example, the above method has the benefits of: the terminal sending the first type of wireless signals independently configures the air interface resources occupied by the HARQ-ACK, so that the flexibility and the efficiency of HARQ-ACK transmission are improved; however, the flexible way of configuring HARQ-ACK air interface resources may cause collision of the configured HARQ-ACK resources and collision with the SCI for scheduling sent by the first node, which further requires the scheme proposed in the present application; that is, the first node determines, according to the value of K or the channel decoding result of K first-type wireless signals, whether to embed the K HARQ-ACK information into the scheduled SCI for transmission together, or to transmit only the K HARQ-ACK information and abandon the scheduling.

sending a second signaling;

the second signaling comprises K first-class indexes which are respectively associated with K terminals.

As an example, the above method has the benefits of: k first-class indexes are configured for K terminals, and the terminal to which the transmitted HARQ-ACK information belongs is distinguished through the K first-class indexes.

transmitting a target wireless signal;

wherein the first signaling comprises the target configuration information.

As an example, the above method has the benefits of: and HARQ-ACK information is embedded in the scheduling SCI, so that the control signaling overhead is reduced.

According to an aspect of the present application, the above method is characterized in that the first signaling does not include the target configuration information and the first signaling includes a first domain; the first field included in the first signaling includes a given subzone that is used to determine whether a given wireless signal of the K first class of wireless signals is correctly received; the position of the air interface resource occupied by the given sub-domain included in the first domain in the first signaling is related to the position of the first-class index corresponding to the sender of the given wireless signal in the K first-class indexes.

As an example, the above method has the benefits of: when K is larger or the channel decoding results of the K first-class wireless signals are not identical, the first signaling is completely used for sending K HARQ-ACK information and is not used for scheduling, so that the load size occupied by the K HARQ-ACK information is saved.

According to an aspect of the present application, the method is characterized in that the first signaling further includes K2 first-class indexes in the K first-class indexes, where K2 is a positive integer smaller than K, and the K2 first-class indexes included in the first signaling are respectively used to determine that K2 first-class wireless signals respectively corresponding to the K2 first-class indexes are correctly received.

As an example, the above method has the benefits of: when the number of the first-class wireless signals which are correctly received in the K first-class wireless signals is small and the first-class index for identifying the terminal is short, the first signaling comprises scheduling and HARQ-ACK information, so that the transmission efficiency is improved, and the scheduling delay is reduced.

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

transmitting a first wireless signal;

receiving a first signaling;

wherein the first wireless signal is one of K wireless signals of a first type, and the first signaling is used to indicate whether the K wireless signals of the first type are correctly received; whether the first signaling comprises target configuration information related to the value of K or whether the first signaling comprises target configuration information related to channel coding results for the K first type wireless signals; the target configuration information is used for scheduling target wireless signals for target terminals, the senders of the K first-type wireless signals are K terminals respectively, and at least one terminal of the K terminals is non-co-located with the target terminal; the second node is one of the K terminals.

transmitting third signaling, wherein the third signaling is used for indicating the first air interface resource;

the third signaling is one of K first-type signaling, where the K first-type signaling respectively indicates K first-type air interface resources, and the first air interface resource is a first-type air interface resource indicated by the third signaling in the K first-type air interface resources; the K first type air interface resources are respectively reserved for K HARQ-ACKs, and the K HARQ-ACKs are respectively associated with the K first type wireless signals.

receiving a second signaling;

receiving a target wireless signal;

wherein the first signaling comprises the target configuration information.

According to an aspect of the present application, the above method is characterized in that the first signaling does not include the target configuration information and the first signaling includes a first domain; the first field included in the first signaling includes a given subzone, the given subzone included in the first field being used to determine whether a given wireless signal of the K first class of wireless signals is correctly received; the position of the air interface resource occupied by the given sub-domain included in the first signaling in the first domain is related to the position of the first-class index corresponding to the sender of the given wireless signal in the K first-class indexes.

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

the first transceiver module is used for receiving K first-class wireless signals, wherein K is a positive integer;

a first transmitter module that transmits a first signaling;

wherein the first signaling is used to indicate whether the K first type wireless signals are correctly received; whether the first signaling comprises target configuration information related to the value of K or whether the first signaling comprises target configuration information related to channel coding results for the K first type wireless signals; the target configuration information is used to schedule target wireless signals for target terminals, the senders of the K first type wireless signals are K terminals respectively, and at least one of the K terminals is non-co-located with the target terminal.

a first receiver module to receive a first signaling;

wherein the first wireless signal is one of K first type wireless signals, and the first signaling is used for indicating whether the K first type wireless signals are correctly received; whether the first signaling comprises target configuration information related to the value of K or whether the first signaling comprises the target configuration information related to channel coding results for the K first-class wireless signals; the target configuration information is used for scheduling target wireless signals for a target terminal, senders of the K first-class wireless signals are K terminals respectively, and at least one terminal in the K terminals is non-co-located with the target terminal; the second node is one of the K terminals.

As an example, compared with the conventional scheme, the method has the following advantages:

when the first node performs sidelink communication with K terminals at the same time and there is a collision with K HARQ-ACK messages for the K terminals, the above scheme can ensure that the K HARQ-ACK messages are all sent out under higher spectrum efficiency, and the specific implementation manner includes: when the value of K is smaller or the K first-class wireless signals are all correctly received, the K HARQ-ACK information can be sent to the K terminals by adopting fewer bits, and then the first node directly sends the K HARQ-ACK information by adopting SCI containing scheduling information; when the value of K is large, or the K first-class wireless signals are not all correctly received, and the first node needs to distinguish HARQ-ACKs targeted by the first-class wireless signals from different terminals, the first node can only send the K HARQ-ACK information by using the SCI which specially sends the K HARQ-ACK information and does not contain scheduling information; by the method, the first node dynamically selects the format adopted by the first signaling, so that the problem of high control signaling overhead caused by the fact that the first signaling occupies too many air interface resources is solved.

The empty resources occupied by the HARQ-ACK are independently configured through the terminal, so that the flexibility and the efficiency of the HARQ-ACK transmission are improved; however, the flexible way of configuring HARQ-ACK air interface resources may cause collision of the configured HARQ-ACK resources and collision with the SCI of the first node for scheduling, which requires the scheme proposed in the present application; that is, the first node determines whether to embed the K HARQ-ACK messages into the scheduled SCI for transmission together or to transmit only the K HARQ-ACK messages and abandon the scheduling according to the K values or the channel decoding results of the K first-type wireless signals.

Example 3

Embodiment 3 shows a schematic diagram of an embodiment of a radio protocol architecture for the user plane and the control plane according to the present application, as shown in fig. 3.

Fig. 3 is a schematic diagram illustrating an embodiment of a radio protocol architecture for the user plane and the control plane, fig. 3 showing the radio protocol architecture for the User Equipment (UE) and the base station equipment (gNB or eNB) in three layers: layer 1, layer 2 and layer 3. 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 PHY301. Layer 2 (L2 layer) 305 is above PHY301 and is responsible for the link between the UE and the gNB through PHY301. In the user plane, 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 gNB on the network side. Although not shown, the UE may have several upper layers above the L2 layer 305, including a network layer (e.g., IP layer) that terminates at the P-GW on the network side and an application layer that terminates at the other end of the connection (e.g., far end UE, server, etc.). The PDCP sublayer 304 provides multiplexing between different radio bearers and logical channels. The PDCP sublayer 304 also provides header compression for upper layer data packets to reduce radio transmission overhead, security by ciphering the data packets, and handover support for UEs between gnbs. 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 (Hybrid Automatic Repeat reQuest). The MAC sublayer 302 provides multiplexing between logical and transport channels. The MAC sublayer 302 is also responsible for allocating various radio resources (e.g., resource blocks) in one cell among the UEs. The MAC sublayer 302 is also responsible for HARQ operations. In the control plane, the radio protocol architecture for the UE and the gNB is substantially the same for the physical layer 301 and the L2 layer 305, but there is no header compression function for the control plane. The Control plane also includes a RRC (Radio Resource Control) sublayer 306 in layer 3 (L3 layer). The RRC sublayer 306 is responsible for obtaining radio resources (i.e., radio bearers) and configures the lower layers using RRC signaling between the gNB and the UE.

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 450 and a second communication device 410 communicating with each other in an access network.

The first communications device 450 includes a controller/processor 459, a memory 460, a data source 467, a transmit processor 468, a receive processor 456, a multiple antenna transmit processor 457, a multiple antenna receive processor 458, a transmitter/receiver 454, and an antenna 452.

The second 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.

In the transmission from the second communication device 410 to the first communication device 450, at the second 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 the L2 layer. In transmissions from the second 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 first 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 first communication device 450, as well as 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 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 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 second communications apparatus 410 to the first communications apparatus 450, each receiver 454 receives a signal through its respective antenna 452 at the first communications apparatus 450. 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 first 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 second communication 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 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 transmissions from the second 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 first communications device 450 to the second communications device 410, a data source 467 is used at the first 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 send function at the second communications apparatus 410 described in the transmission from the second communications apparatus 410 to the first 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 second 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 first communication device 450 to the second communication device 410, the functionality at the second communication device 410 is similar to the receiving functionality at the first communication device 450 described in the transmission from the second communication device 410 to the first 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 functions of the L1 layer. The controller/processor 475 implements 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 transmission from the first communication device 450 to the second communication 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 first communication device 450.
