Description

Under the 3rd Generation Partnership Project (3GPP) specification for 5th Generation (5G) NR, vehicle-to-everything (V2X) SL communication can be carried out through unicast, multicast and broadcast communication. However, there are still some problems that need to be solved in the energy saving of resource allocation for SL communication through partial awareness. Therefore, there is a need for a partial awareness enhancement solution for SL resource configuration.

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

The embodiments of the present invention relate to various technologies, methods, solutions and/or solutions related to partial perception enhancement for SL resource configuration in NR V2X communication. According to the invention, several possible solutions are implemented individually or in combination. That is, although these possible solutions are described individually below, two or more of these possible solutions may also be implemented in combination or otherwise.

Under the proposed scheme for SL resource configuration according to the present invention, user equipment (UE) can perform partial awareness for resource configuration and transmission while saving power. Under the proposed scheme, in order to preserve the sensing performance while saving power, the UE can perform aperiodic one-shot sensing (may be referred to here as "continuous sensing" and "continuous partial sensing") and periodic sensing to Detect any resource reservation for periodic transmission and aperiodic transmission by other UEs, thereby preventing the UE from reserving resources already reserved by other UEs.

That is, for partial sensing, once the UE has identified one or more candidate resources for receiving packets within a selected window relative to the packet arrival time (eg, after the packet arrival time), given the periodic nature of partial sensing, for each a candidate resource, the UE can backtrack to detect the corresponding periodic sensing and aperiodic sensing to determine whether the candidate resource has been reserved by any other UE. Then, 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 transmitting packets. Under the proposed scheme, in addition to periodic sensing, the UE can additionally perform continuous sensing, that is, after knowing the packet arrival time, the UE can backtrack based on the packet arrival time to perform continuous sensing. The duration of continuous sensing can be longer than the duration of periodic sensing to detect any aperiodic traffic/activity/reservation that falls outside the periodic sensing window to avoid reserved resources being subject to periodic traffic from other UEs and interference effects of aperiodic traffic.

To detect periodic transmissions, periodic sensing patterns defined by periodicity, sensing duration and/or time offset can be used. To detect aperiodic transmission, aperiodic (or continuous) sensing can be applied. This sense of continuity may occur prior to resource selection or reselection (hereinafter referred to as "(re)selection") of one or more of the plurality of candidate resources having N slot durations. Considering that the sidelink control information (SCI) can indicate a reserved resource of up to 32 slots from the current time, N can be set to 31 or 32 so that the non-reservation can be sensed in the past 31 or 32 slots. Periodic resource reservation.

Under the proposed scheme, continuous sensing can be performed periodically if there is a periodic data transmission with continuous sensing before each transmission for resource (re)selection. In this case, for this periodic data transmission, the sensing can be regarded as bi-periodic sensing. Furthermore, continuous awareness may be applied prior to transmitting or (re)selecting any reserved or (re)selected resources. Furthermore, the resource (re)selection window may include the overlapping time between the periodic sensing mode and the duration for which continuous sensing is performed to avoid the influence or interference of any periodic and/or aperiodic transmissions from other UEs). This partial awareness can be especially beneficial to vulnerable users (VRUs) to save power.

FIG. 1 illustrates an example scenario 100 of the process of a UE performing partial awareness of resource configuration under the proposed scheme of the present invention. In scenario 100, assuming that the UE has periodic traffic for transmission every 1 second, the UE may perform periodic sensing every P1 timeslots or P1 milliseconds, where m timeslots or mms (eg, 10 timeslots) or 10 ms) of duration D1 for other UEs to detect periodic reservations so that any other periodic transmissions with periodicity that is a multiple of P1 can be detected. The P1/D1 pattern can be used to sense periodic reservations by other UEs. P1 can be exported from a (pre-)configured reservation period per resource pool. The time offset for the P1/D1 pattern can 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 of a potential transmission is at time R1, it can be considered as the start time of D1. Therefore, the P1/D1 pattern can be determined. Advantageously, partial sensing results can be used in time for resource (re)selection without any delay impact on packet transmission. For example, the location of D1 may be {t,t+m} with period P1, where t is the packet arrival time or resource (re)selection time. Additionally, 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.

As shown in Figure 1, the UE may perform another sensing (or continuous sensing) every P2 slots/P2 ms, where m slots or a duration of m ms (eg, 31 slots or 31 ms) D2 is used for other UEs to detect grant-based (aperiodic) reservations. For example, P2 may be set to 1 second, eg the same period as the periodic transmission. This sensing may occur before the (re)selection time determined by the UE based on the packet arrival time and processing time. Therefore, any other aperiodic transmissions that fall within the selection window can be detected. P2/D2 mode can be used to sense aperiodic reservations or multiple resource reservations, up to 32 slots as indicated by the SCI. In other words, D2 can be (pre)configured or assigned up to 32 time slots. The perceived end time can be before or at the time of the (re)selection of the resource. For example, the perceived end time may be the time of resource (re)selection (or packet arrival time) minus the processing time (T_proc), eg, t – T_proc. Therefore, the start time sensed by D2 can be derived from the end time and the value of D2, eg, t – T_proc – 32, where D2 = 32 slots.

Under the proposed scheme, the UE (or VRU) can select resources for transport block (TB) (re)transmissions during a selection window including at least: P1/D1 pattern, perceived in D2 with potentially aperiodic The duration and/or Packet Delay Budget (PDB) of the sexual transmission. In the case where D2 sensing occurs at {t-m,t}, the duration in D2 with potentially aperiodic transmission through sensing may be {t,t+m}. Taking into account 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, the overlapping duration between the P1/D1 pattern and the duration with potentially aperiodic transmission by sensing in D2 can be prioritized for resource (re)selection due to sufficient sensing information. In addition, a packet delay budget can be considered for resource (re)selection so that the delay requirements of the packet can be met.

Under the proposed scheme, for reselection of resources due to re-evaluation or preemption, one-time awareness of D2 locations derived from the reselection time or the time used to reserve resources can still be used. For example, as shown in FIG. 1, in the case where time R2 preempts the resources reserved at time R1, the UE may perform D2 sensing at the time when time R2 minus T3 or an end time before that. Here, T3 may be the processing time T_proc. Meanwhile, P1/D1 sensing can be performed anyway. Therefore, reselection of resources can be based on P1/D1 awareness, updated D2 awareness and packet delay budget.

Under another proposed scheme, an indicator can be carried in the SCI sent by one UE to indicate to other UEs that the UE sending the SCI is a partially sensing UE that needs to save power, so that other UEs can use the sensing duration during the sensing duration Data is sent to partially aware UEs (eg, during periodic sensing durations and/or continuous sensing durations). Furthermore, under the proposed scheme, a common SL discontinuous reception (DRX) mode can be configured for such partially aware UEs. Therefore, when any other UE transmits material to a partially aware UE, the transmitting UE may select resources for the SL DRX_On duration (during which the UE is in active and not sleeping mode) for transmission. Furthermore, in the case of establishing SL unicast, the sending UE may further follow the sensing mode of the partially aware UE, based on the signaling exchange between the sending UE and the partially aware UE (eg, PC5 interface-Radio Resource Control (PC5-RRC) signaling exchange) for data reception. Therefore, a partially aware UE may be active (eg 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 (eg, in periodic and one-shot sensing windows) for unicast reception and sensing, and/or its own transmission time. For other durations, in addition to any SL synchronization time if necessary, partially aware UEs may enter sleep mode to save power. For example, a partially sensing UE may only perform sensing on the physical sidelink control channel-demodulation reference signal (PSCCH-DMRS), so that since the PSCCH preload is in one slot, the partially sensing UE can perform sensing at the end of the slot. The remaining time goes into micro-sleep mode.

Figure 2 illustrates an example scenario 200 under the proposed scheme in accordance with the present invention. Scenario 200 may involve two UEs, represented as UE A and UE B in FIG. 2 . Referring to Figure 2, UE A may perform sensing and data reception during the receive (Rx) duration when the SL DRX pattern of UE A may be aligned or overlapped (completely or partially) with the partial sensing pattern. Additionally, UE B may send data during UE A's Rx duration. This Rx mode of UE A may be informed to UE B based on the (pre-)configuration of each resource pool or PC5-RRC signaling or broadcast information. A partial awareness or indicator of a VRU type UE in UE A's SCI may help UE B to export or determine UE A's Rx mode associated with some (pre)configuration. Additionally, UE B can follow a transmit (Tx) mode to receive transmissions from UE A, thereby reducing UE B's complexity and power consumption by avoiding full-time detection of transmissions from UE A.
