In the following description, the details of known features and technologies may be omitted to avoid unnecessarily obscuring the presented embodiments and implementations.

[0017] Overview

[0018] Embodiments of the present invention relate to various technologies, methods, schemes and / or solutions for partial perception enhancement for SL resource allocation in NR V2X communication. According to the present invention, multiple possible solutions are implemented individually or in combination. That is, although these possible solutions are described separately below, two or more of these possible solutions may also be implemented in combination or in another manner.

[0019] Under the proposed scheme for SL resource allocation according to the present invention, a user equipment (UE) can perform partial sensing for resource allocation and transmission while saving power. Under the proposed scheme, in order to maintain sensing performance while saving power, the UE can perform non-periodic one-time sensing (which may be referred to as "continuous sensing" and "continuous partial sensing") and periodic sensing to detect any resource reservations of other UEs for periodic transmission and non-periodic transmission, thereby avoiding the UE from reserving resources that have been reserved by other UEs.

[0020] That is, for partial sensing, once the UE identifies one or more candidate resources for receiving packets within a selection window relative to a packet arrival time (e.g., after a packet arrival time), considering the periodic nature of partial sensing, for each candidate resource, the UE may backtrack to detect corresponding periodic sensing and aperiodic sensing to determine whether the candidate resource has been reserved by any other UE. Subsequently, based on the detection result, the UE may select and reserve one or more resources that have not been periodically reserved by another UE for receiving or sending packets. Under the proposed scheme, in addition to periodic sensing, the UE may additionally perform continuous sensing, i.e., after knowing the packet arrival time, the UE may backtrack based on the packet arrival time to perform continuous sensing. The duration of continuous sensing may be longer than the duration of periodic sensing to detect any aperiodic traffic / activity / reservation that falls outside the periodic sensing window to avoid the reserved resources from being interfered by periodic traffic and aperiodic traffic of other UEs.

[0021] In order to detect periodic transmissions, a periodic sensing pattern defined by periodicity, sensing duration and / or time offset may be used. In order to detect non-periodic transmissions, non-periodic (or continuous) sensing may be applied. Such continuous sensing may occur before resource selection or reselection (hereinafter referred to as "(re)selection") of one or more resources among a plurality of candidate resources having a duration of N time slots. Considering that the sidelink control information (SCI) may indicate a reserved resource up to 32 time slots from the current time, N may be set to 31 or 32 so that the non-periodic resource reservation may be sensed in the past 31 or 32 time slots.

[0022] Under the proposed scheme, continuous sensing may be performed periodically if there is a periodic data transmission with continuous sensing before each transmission for resource (re)selection. In this case, sensing may be considered as dual-periodic sensing for such periodic data transmission. Furthermore, continuous sensing may be applied before transmission or (re)selection of any reserved or (re)selected resource. Furthermore, the resource (re)selection window may include an overlapping time between the periodic sensing mode and the duration over which continuous sensing is performed to avoid the impact or interference of any periodic and / or non-periodic transmissions from other UEs). Such partial sensing may be particularly beneficial for vulnerable users (VRUs) to save power.

[0023] Figure 1An example scenario 100 of a process of performing partial sensing of resource allocation by a UE according to the proposed solution of the present invention is illustrated. In scenario 100, assuming that the UE has periodic traffic for transmission every 1 second, the UE may perform periodic sensing with a duration D1 length of m time slots or m milliseconds (e.g., 10 time slots or 10 milliseconds) every P1 time slot or P1 millisecond for other UEs to detect periodic reservations, so that any other periodic transmissions with a periodicity multiple of P1 may be detected. The P1 / D1 pattern may be used to sense the periodic reservations of other UEs. P1 may be derived from the (pre)configured reservation period of each resource pool. The time offset of the P1 / D1 pattern may be derived from the known packet arrival time or resource (re)selection time at the receiving UE. If the earliest available time or packet arrival time or resource (re)selection time for a potential transmission is at time R1, it may be considered as the start time of D1. Therefore, the P1 / D1 pattern may be determined. Advantageously, the partial sensing result may be used for resource (re)selection in a timely manner without any delay effect on packet transmission. For example, the position of D1 can be {t, t+m} with period P1, where t is the packet arrival time or resource (re)selection time. In addition, some processing time or minimum time offset (MinT) can be added so that the position of D1 can be {t+MinT, t+MinT+m} with period P1.

[0024] like Figure 1 As shown, the UE may perform another sensing (or continuous sensing) every P2 slots / P2 milliseconds, where a duration D2 of m slots or m milliseconds (e.g., 31 slots or 31 milliseconds) is used for other UEs to detect grant-based (non-periodic) reservations. For example, P2 may be set to 1 second, for example the same as the period of the periodic transmission. This sensing may occur before the (re)selection time determined by the UE based on the packet arrival time and the processing time. Thus, any other non-periodic transmission falling within the selection window may be detected. The P2 / D2 pattern may be used to sense non-periodic reservations or multiple resource reservations, up to 32 slots as shown in the SCI. In other words, D2 may be (pre)configured or specified for up to 32 slots. The end time of sensing may be before or at the time of the (re)selection of the resource. For example, the end time of sensing may be the time of resource (re)selection (or packet arrival time) minus the processing time (T_proc), for example, t–T_proc. Therefore, the D2-aware start time can be derived from the end time and the value of D2, for example, t - T_proc - 32, where D2 = 32 time slots.

[0025] Under the proposed scheme, a UE (or VRU) may select resources for a transport block (TB) (re)transmission during a selection window that includes at least: a P1 / D1 pattern, a duration with potential aperiodic transmission sensed in D2, and / or a packet delay budget (PDB). In the case where D2 sensing occurs at {tm, t}, the duration with potential aperiodic transmission sensed in D2 may be {t, t+m}. Considering some processing time before and / or after t, if D2 sensing occurs at {t–D2–T_proc, t–T_proc} or {t–D2–MinT, t–MinT}, the duration may be {t+MinT, t+m–MinT} or {t+MinT, t+m–2*MinT} or {t+MinT, t+m–MinT–T_proc}. Ideally, due to sufficient sensing information, the overlapping duration between the P1 / D1 pattern and the duration with potential aperiodic transmission sensed in D2 may be prioritized for resource (re)selection. Furthermore, a packet delay budget may be considered for resource (re)selection so that the packet delay requirement may be met.

[0026] Under the proposed scheme, for the reselection of resources due to re-evaluation or preemption, the one-time perception of the D2 position derived from the reselection time or the time used to reserve resources can still be used. Figure 1 As shown, in the case where time R2 preempts the resources reserved at time R1, the UE can perform D2 sensing at or before the end time of time R2 minus T3. Here, T3 can be the processing time T_proc. At the same time, P1 / D1 sensing can be performed anyway. Therefore, the reselection of resources can be based on P1 / D1 sensing, updated D2 sensing and packet delay budget.

[0027] Under another proposed scheme, an indicator may be carried in the SCI sent by a UE to indicate to other UEs that the UE sending the SCI is a partially aware UE that needs to save power, so that other UEs may send data to the partially aware UE during the sensing duration (e.g., during the periodic sensing duration and / or the continuous sensing duration). In addition, under the proposed scheme, a common SL discontinuous reception (DRX) mode may be configured for such partially aware UEs. Therefore, when any other UE sends data to the partially aware UE, the sending UE may select resources during the SL DRX_On duration (during which the UE is active and not in sleep mode) for transmission. In addition, in the case of establishing SL unicast, the sending UE may further follow the sensing mode of the partially aware UE and receive data based on the signaling exchange between the sending UE and the partially aware UE (e.g., PC5 interface-radio resource control (PC5-RRC) signaling exchange). Thus, a partially aware UE may be active (e.g., not in sleep or low power mode) during the (common) SL DRX_On duration used for broadcast / unicast reception (and sensing), its own partial sensing duration (e.g., in periodic and one-time sensing windows) for unicast reception and sensing, and / or its own transmission time. For other durations, the partially aware UE may enter sleep mode to save power, except for any SL synchronization time when necessary. For example, the partially aware UE may only perform sensing on the Physical Sidelink Control Channel-Demodulation Reference Signal (PSCCH-DMRS), so that, due to the PSCCH pre-loading in one time slot, the partially aware UE may enter micro-sleep mode for the rest of the time slot.

[0028] Figure 2 An example scenario 200 according to the proposed solution of the present invention is shown. The scenario 200 may involve two UEs. Figure 2 In the figure, UE A and UE B are represented. Figure 2, when the SL DRX pattern of UE A can be aligned or overlapped (completely or partially overlapped) with the partial sensing pattern, UE A can perform sensing and data reception during the reception (Rx) duration. In addition, UE B can send data during the Rx duration of UE A. UE B can be informed of this Rx mode of UE A based on the (pre) configuration of each resource pool or PC5-RRC signaling or broadcast information. The indicator of partial sensing or VRU type UE in the SCI of UE A can help UE B derive or determine the Rx mode of UE A associated with some (pre) configuration. In addition, UE B can follow the transmission (Tx) pattern to receive transmissions from UE A, thereby reducing the complexity and power consumption of UE B by avoiding full-time detection of transmissions from UE A.
