This application relates to the field of communication technologies, and in particular, to a sidelink resource processing and indication method, an apparatus, a terminal, and a network-side device.
Some sidelink (SL) terminals (User Equipment, UE) may have poor battery life, so that the sidelink terminals may obtain transmission resources in a random selection mode.

The following clearly and completely describes the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are some of the embodiments of this application rather than all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of this application fall within the protection scope of this application.
The specification and claims of this application, and terms “first” and “second” are used to distinguish similar objects, but are unnecessarily used to describe a specific sequence or order. It should be understood that the terms in such a way are interchangeable in proper circumstances, so that the embodiments of this application can be implemented in other orders than the order illustrated or described herein. Objects distinguished by “first”, “second”, and the like are usually one type, and the number of objects is not limited. For example, the first object may be one or more than one. In addition, in the specification and the claims, “and/or” represents at least one of the connected objects, and the character “/” generally represents an “or” relationship between the associated objects.
It should be noted that, the technologies described in the embodiments of this application are not limited to a Long Term Evolution (LTE) system or an LTE-Advanced (LTE-A) system, and may further be applied to other wireless communication systems, such as, Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), and other systems. The terms “system” and “network” in the embodiments of this application are often used interchangeably, and the described technology can be used not only for the above systems and radio technologies, but also for other systems and radio technologies. The following description describes a new radio (NR) system for example objectives, and NR terms are used in most of the description below, although these technologies are also applicable to applications other than NR system applications, such as a 6-th generation (6G) communication system.
A basic working principle of LTE sidelink sensing is as follows:
Measurement is performed within a sensing window, a scheduling assignment (SA) is demodulated and an interference measurement is performed within each sensing transmission time interval (TTI). The UE performs resource selection based on the following steps:
Exclude a resource for UE to send data.
The terminal demodulates a received SA to obtain a resource reserved by another UE, and excludes the resource reserved by another UE.
Perform energy sensing in the sensing window, measure a reference signal strength indication (reference signal strength indication, RSSI), and exclude a resource with large interference based on a measurement result.
Within the selection window, a subframe is randomly selected from the 20% resource with a minimum interference for periodic resource reservation.
Part of the sensing in LTE vehicle to everything (Vehicle to X, V2X) is mainly designed for power saving, to support pedestrian to vehicle (P2V) communication, and pedestrian user (PUE) supports two modes of resource selection. One is random resource selection, and the other is to perform partial sensing first, select a resource based on a result of the partial sensing, and perform semi-static resource reservation. Which mode the PUE chooses is configured for radio resource control (RRC). When the RRC is configured to support two modes of resource selection, a PUE implementation decides which resource selection to adopt.
In some embodiments, a manner in which the terminal performs partial sensing and resource selection is shown in
A PUE sensing window is a window of a lattice-filled part within a range of [n−1000, n], lengths Y and k are parameters configured by RRC, and a value range of k may be {1, 2, 3, . . . , 10}. A dot-filled part of a window within [n+T1, n+T2] is a selection window of the PUE configured by a higher layer. The PUE performs sensing on sidelink control information (SCI) sent by another terminal in the sensing window (the lattice-filled part), and estimates a resource reservation status of another terminal in the selection window (the dot-filled part) based on a sensed SCI and a reserved period. The PUE may exclude resources that do not meet a condition in the sensing window based on the information. At least 20% of the remaining resources (20% of a window length Y) are selected as a candidate resource set, and reported to a media access control (Media Access Control, MAC) layer. The MAC layer randomly selects a resource from the candidate resource set as a candidate resource of the PUE. The PUE performs cycle reservation on the selected resource, and the reserved period is indicated in the SCI.
If a user makes a random selection, the resource is randomly selected within the selection window in
In a mode 2 resource allocation mode, resource selection based on sensing is supported. A principle of the resource selection is similar to a sensing mechanism in LTE SL mode4. A working manner is as follows: 1) After a resource selection is triggered, a transmit UE (TX UE) determines a resource selection window. 2) Before the resource selection, the UE needs to determine a candidate resource set for the resource selection, and compares reference signal receiving power (RSRP) measured based on a resource in the resource selection window with a corresponding RSRP threshold. If the RSRP is lower than the RSRP threshold, the resource may be included in the candidate resource set. 3) After the resource set is determined, the UE randomly selects transmission resources from the candidate resource set. In addition, the UE may reserve transmission resources for next transmission during current transmission.
In a relevant NR SL, the TX UE performs resource reservation on resources allocated by itself (reservation is divided into periodic reservation and aperiodic reservation), and the reserved resources are used for future physical sidelink control channel (PSCCH) and/or physical sidelink shared channel (PSSCH) transmission. The aperiodic reservation may be implemented through a time resource assignment domain in the SCI, and the reserved resources may be used at least for the transmission of a same transport block (TB). The periodic reservation may be implemented through a resource reservation period domain in the SCI, and periodic resources reserved in a current period may be used for the transmission of a next TB.
In the NR, in addition to performing sensing on a periodic sensing window or a periodic sensing occasion corresponding to a partial sensing, as shown in
In a Mode 2 resource allocation mode, a resource pre-emption (pre-emption) mechanism is supported, and a brief description of the mechanism is as follows. The resource reserved/selected by a UE overlaps (partially overlaps) with a resource reserved/selected by another UE with a higher priority service, if a SL-RSRP measurement value of the UE on a relevant resource is greater than a certain associated SL-RSRP threshold, the UE triggers resource re-selection. The service priority and the SL-RSRP threshold are determined by TB transmission on the resource.
In order for the UE to determine whether the reserved/selected resource (PSCCH/PSSCH resources) is preempted, as shown in
Time is required for preparations of channel/signal decoding, channel/signal transmission, resource selection, and the like, and these time may be related to a sub-carrier spacing (SCS) of transmission in the following, for example:
1. Time required for decoding SCI is shown in Table 1:
2. Time required for resource selection/resource re-selection is shown in Table 2:
3. Congestion control processing time is shown in Table 3 and Table 4
4. PSSCH data transmission preparation time is shown in Table 5;
5. Preparation time Tprep for reporting on PUCCH or PUSCH is calculated by the following formula:
T
prep=(N+1)·(2048+144)·κ·2−μ·Tc

In the embodiments of this application, a terminal obtains a target sidelink object, and first information about the target sidelink object meets a first condition. The terminal performs resource sensing and/or resource selection on the target sidelink object, and the first condition may be that a duration between a selection window and a sensing window needs to include at least required processing time, so that a good balance can be achieved between power consumption of the terminal and performance of a communication system.

For example, when the value of the preset parameter is 1, the value of the first information is A. and a length of the selection window is Y1. For another example, when the value of the preset parameter is 2, the value of the first information is A, and the length of the selection window is Y2.
