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 scheme and apparatus related to a Sidelink (sidlink) in wireless communication.

Background

Starting from LTE (Long Term Evolution ), 3GPP (3 rd Generation Partner Project, third generation partnership project) has been developing SL (Sidelink) as a direct communication means between users, and the first NR SL (New Radio Sidelink, new air interface Sidelink) standard of "5G V2X with NR Sidelink" has been completed in Rel-16 (Release-16, release 16). In Rel-16, NR SL is mainly designed for V2X (Vehicle-To-evaluation), but it can also be used for Public Safety (Public Safety).

However, due to time constraints, NR SL Rel-16 cannot fully support the service requirements and operating scenarios identified by 3GPP for 5g v2 x. The 3GPP will therefore study enhanced NR SL in Rel-17.

Disclosure of Invention

In the NR SL system, random resource selection is allowed, and partially perceived and fully perceived UEs (User Equipment) share the same resource pool, and when one perceived UE perceives a time-frequency resource occupied by a neighboring VRU (Vulnerable road User, a weak road User) or PUE (Pedestrian User Equipment, a pedestrian User Equipment), although the perceived UE has a higher data priority than the neighboring VRU or PUE, the VRU or PUE adopts a random resource selection manner and does not execute channel perception, so that interference to the neighboring UE cannot be avoided, and perceived UEs have to adopt a time-frequency resource for actively avoiding interference, so that the transmission performance of the perceived UE at a high end is affected. Therefore, companies propose to divide a plurality of resource areas in one resource pool, and UEs adopting different resource determination manners can allocate resources in different resource areas, so as to avoid resource conflicts to a certain extent. But still cause a collision when the UE is perceived to select resources of the random resource selection region.

In view of the above problems, the present application discloses a method for allocating resources, so as to effectively avoid the problem of resource collision between UEs sharing a resource pool. It should be noted that, without conflict, the embodiments in the user equipment and the features in the embodiments of the present application may be applied to the base station, and vice versa. The embodiments of the present application and features in the embodiments may be combined with each other arbitrarily without conflict. Further, while the purpose of the present application is for SL, the present application can also be used for UL (Uplink). Further, while the present application is primarily directed to single carrier communications, the present application can also be used for multi-carrier communications. Further, while the present application is primarily directed to single antenna communications, the present application can also be used for multiple antenna communications. Further, although the present application is initially directed to a V2X scenario, the present application is also applicable to a communication scenario between a terminal and a base station, between a terminal and a relay, and between a relay and a base station, to achieve similar technical effects in a V2X scenario. Furthermore, the adoption of a unified solution for different scenarios (including but not limited to V2X scenarios and communication scenarios of terminals with base stations) also helps to reduce hardware complexity and cost.

It should be noted that the term (terminal) in the present application is explained with reference to the definitions in the specification protocols TS36 series, TS37 series and TS38 series of 3GPP, but can also refer to the definitions of the specification protocols of IEEE (Institute of Electrical and Electronics Engineers ).

the problem to be solved by the present application is: when UEs adopting different resource allocation schemes share a resource pool, non-sensing UE cannot avoid interference to adjacent UE, sensing UE has to take time-frequency resources actively avoiding interference, and the transmission performance of high-end sensing UE is influenced;

In the application, for the perceived UE, in different resource areas of the shared resource pool, a resource area which only allows execution of a perceived-based resource determination mode is preferentially selected, and when the number of alternative resources is insufficient, resources are perceived from the resource area selected based on partial perception or random resources, so that resource conflict of the perceived UE in the shared resource pool is reduced, and a certain amount of available resources is ensured;

in this application, the aware UE has enough available resources, and can avoid resource conflicts with the non-aware UE as much as possible.

To save power overhead, a period-based partially perceived resource allocation method will be introduced in the NR SL enhancement system. The 3GPP has agreed that the period-based partial awareness sensing period is selected from a set of periods of the higher layer signaling configuration. The periods in the set of periods may be configured with larger period values, resulting in monitoring on very sparse resources based on partial awareness of the periods to save power overhead. According to the SL service requirements, the time interval between the resources occupied by the periodically transmitted SL packets may be small, while sparse resource awareness cannot provide reliable available resources for the densely transmitted SL packets, resulting in a large probability of resource collision. Therefore, companies propose to introduce the transmission period of the SL packet into the period-based partial awareness flow, but this tends to increase the power overhead, and if the transmission periods of the SL packets of different users are not uniform, the collision probability tends to increase.

In view of the above, the present application discloses a method for allocating resources based on periodic partial awareness, so as to obtain a reliable balance between resource awareness and power overhead. It should be noted that, without conflict, the embodiments in the user equipment and the features in the embodiments of the present application may be applied to the base station, and vice versa.

Further, while the present application is primarily directed to single antenna communications, the present application can also be used for multiple antenna communications. Further, although the present application is initially directed to a V2X scenario, the present application is also applicable to a communication scenario between a terminal and a base station, between a terminal and a relay, and between a relay and a base station, to achieve similar technical effects in a V2X scenario. Furthermore, the adoption of a unified solution for different scenarios (including but not limited to V2X scenarios and communication scenarios of terminals with base stations) also helps to reduce hardware complexity and cost.

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 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 first 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.
