Description

Partially Aware Enhanced Mechanism for Sidelink Resource Allocation

The present invention relates generally to wireless communications and, more particularly, to a partial sensing enhancement mechanism for sidelink (SL) resource allocation.

Unless otherwise indicated, the methods described in this section are not intended to be prior art to the claims listed below and are not admitted to be prior art by inclusion in this section.

Under the 3rd Generation Partnership Project (3GPP) specifications for 5th Generation (5G) NR, vehicle-to-everything (V2X) SL communication can be performed via unicast, groupcast, and broadcast communications. However, there are still some issues to be addressed in terms of energy saving for resource allocation for SL communication through partial sensing. Therefore, a partial sensing enhancement solution for SL resource allocation is required.

That is, the following invention content is provided to introduce the concepts, key points, benefits, and beneficial effects of the novel and non-obvious technology described herein. Selected implementations are further described in the detailed description below. Therefore, the following invention content is not intended to identify the essential characteristics of the claimed subject matter, nor is it intended to be used to determine the scope of the claimed subject matter.

An object of the present invention is to propose various schemes, concepts, designs, methods, systems and devices related to partial perception enhancement mechanism of SL resource configuration. The various schemes proposed here can provide partial perception enhancement mechanism of SL resource configuration as a solution to specific problems in 5G NR V2X communication.

In one aspect, a method may include performing one-shot sensing and periodic sensing operations before a transmission operation. The method may also include selecting a resource based on the results of the one-shot sensing and the periodic sensing. The method may also include performing the transmission operation using the selected resource in SL communication in a V2X network.

In another aspect, a method may include determining whether each of one or more candidate resources is affected by interference caused by periodic and non-periodic transmissions from one or more other UEs in a V2X network. The method may also include selecting a resource from the one or more candidate resources based on the determination result. The method may also include using the selected resource to perform SL communication.

In another aspect, an apparatus may include a transceiver and a processor coupled to the transceiver. The transceiver may be configured to perform wireless communication in SL communication of a V2X network. The processor may be configured to perform the following operations, including: (a) performing one-time sensing and periodic sensing via the transceiver before a transmission operation; (b) selecting resources based on the results of the one-time sensing and periodic sensing; and (c) performing the transmission operation via the transceiver using the selected resources.

The partial perception enhancement method and device of the side link resource configuration proposed by the present invention can reduce power consumption.

Therefore, the scope of the present invention is not limited to the examples described herein.

On the contrary, such exemplary embodiments and implementations are provided so that the description of the invention is comprehensive and complete and will fully convey the scope of the invention to those having ordinary knowledge in the art. In the following description, details of well-known features and techniques may be omitted to avoid unnecessarily obscuring the presented embodiments and implementations. Overview

Embodiments of the present invention relate to various technologies, methods, schemes and/or solutions for partial perception enhancement for SL resource configuration in NR V2X communication. According to the present invention, multiple possible solutions are implemented individually or jointly. 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.

Under the proposed scheme for SL resource configuration according to the present invention, a user equipment (UE) can perform partial sensing for resource configuration 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 (hereinafter referred to as "continuous sensing" and "continuous partial sensing") and periodic sensing to detect any resource reservations for periodic transmission and non-periodic transmission by other UEs, thereby avoiding the UE from reserving resources already reserved by other UEs.

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 can backtrack to detect the corresponding periodic sensing and non-periodic sensing to determine whether the candidate resource has been reserved by any other UE. Subsequently, based on the detection result, the UE can 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 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 may be longer than the duration of periodic sensing to detect any non-periodic traffic/activity/reservation falling outside the periodic sensing window to avoid the reserved resources being affected by the periodic and non-periodic traffic of other UEs.

To detect periodic transmissions, a periodic sensing pattern defined by periodicity, sensing duration and/or time offset may be used. To detect non-periodic transmissions, non-periodic (or continuous) sensing may be applied. Such continuous sensing may occur prior to resource selection or reselection (hereinafter denoted as "(re)selection") of one or more of 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 non-periodic resource reservations may be sensed in the past 31 or 32 time slots.

Under the proposed scheme, continuous sensing may be performed periodically in case there is a periodic data transmission with continuous sensing before each transmission for resource (re)selection. In this case, sensing may be considered as bi-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 overlap time between the periodic sensing mode and the duration of performing continuous sensing to avoid impact or interference from any periodic and/or non-periodic transmissions from other UEs). Such partial sensing may be particularly beneficial for vulnerable users (VRUs) to save power.

FIG. 1 illustrates an example scenario 100 of a process of a UE performing partial perception of resource configuration according to the solution proposed in the present invention. In scenario 100, assuming that the UE has a periodic service for transmission every 1 second, the UE may perform periodic perception every P1 time slot or P1 millisecond, where a duration D1 of m time slots or m milliseconds (e.g., 10 time slots or 10 milliseconds) is used 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 perceive 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 can be derived from the known packet arrival time or resource (re)selection time at the receiving UE. If the earliest available time for potential transmission or the packet arrival time or resource (re)selection time 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 for resource (re)selection in a timely manner without any delay impact 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 P​​1.

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

Under the proposed scheme, a UE (or VRU) may select resources for a transmission block (TB) (re)transmission during a selection window comprising at least: the P1/D1 mode, the duration of the potential aperiodic transmission sensed in D2 and/or the packet delay budget (PDB). In the case where the D2 sensing occurs at {t-m, t}, the duration of the potential aperiodic transmission sensed in D2 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 could 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 potential aperiodic transmission via sensing in D2 could be prioritized for resource (re)selection due to sufficient sensing information. Additionally, a packet delay budget can be considered for resource (re)selection so that the packet delay requirement can be met.

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

Under another proposed scheme, an indicator may be carried in the SCI sent by one 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 UE. 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 partial-aware UE for data reception based on the signaling exchange (e.g., PC5 interface-radio resource control (PC5-RRC) signaling exchange) between the sending UE and the partial-aware UE. Therefore, the partial-aware UE may be in an active state (e.g., not in sleep or low power mode) during the (common) SL DRX_On duration, which is used for broadcast/unicast reception (and sensing), its own partial sensing duration for unicast reception and sensing (e.g., in periodic and one-time sensing windows), and/or its own transmission time. For other durations, except for any SL synchronization time when necessary, the partial-aware UE may enter a sleep mode to save power. For example, a partially aware UE may only perform sensing on the Physical Sidelink Control Channel-Demodulation Reference Signal (PSCCH-DMRS), so that since the PSCCH is pre-loaded in one time slot, the partially aware UE may enter a micro-sleep mode during the rest of the time slot.

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

The subject matter described herein sometimes shows different components contained in or connected to different other components. However, it should be understood that the described architectures are examples only, and in fact many other architectures that realize the same function can be implemented. In a conceptual sense, any arrangement of components that realize the same function is effectively "associated" so that the desired function can be realized. Therefore, regardless of the architecture or intermediate components, any two components combined to realize a specific function herein can be regarded as "associated" with each other so that the desired function can be realized. Similarly, any two components so associated can also be regarded as "operationally connected" or "operationally coupled" to each other to realize the desired function, and any two components that can be so associated can also be regarded as "operationally connected" to each other to realize the desired function. Specific examples of operationally coupleable components include but are not limited to physically matchable and/or physically interacting components and/or wirelessly interactable and/or wirelessly interacting components and/or logically interacting and/or logically interactable components.

Further, with respect to any plural and/or singular terms used in this article, a person skilled in the art may convert from the plural to the singular and/or from the singular to the plural when appropriate for the context and/or application. For the sake of clarity, various singular/plural interchanges may be explicitly stated herein.

Furthermore, one of ordinary skill in the art will understand that, in general, the terms used herein and particularly in the appended claims (e.g., the subject matter of the appended claims) are generally intended to be “open ended” terms, e.g., the term “comprising” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “including” should be interpreted as “including but not limited to,” etc. One of ordinary skill in the art will also understand that if a specific number of an introduced claim listing is intended, such intent will be explicitly recited in the claims, and that such intent is absent in the absence of such recitation. For example, to aid understanding, the appended claims may contain use of the introductory phrases “at least one” and “one or more.” However, the use of such phrases should not be interpreted as implying that the introduction of a claim enumeration by the indefinite article "a" or "an" will limit any particular claim enumeration to including only one implementation of such an enumeration, even when the same claim enumeration contains the introductory phrase "one or more" or "at least one" and an indefinite article such as "a" or "an", for example, "a and/or an" should be interpreted as meaning "at least one" or "one or more", and the same applies to the use of the definite article used to introduce the claim enumeration. In addition, even if a specific number of an introduced claim scope enumeration is expressly enumerated, a person of ordinary skill in the art will recognize that such enumeration should be interpreted to mean at least the enumerated number, e.g., an uncensored enumeration of "two enumerations" means at least two enumerations or two or more enumerations in the absence of other modifiers. In addition, where a convention similar to "at least one of A, B, and C, etc." is used, a person of ordinary skill in the art would understand the convention to be generally meant to be interpreted in this manner (e.g., "a system having at least one of A, B, and C" would include but not be limited to a system having A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). Where a convention similar to "at least one of A, B, or C, etc." is used, a person of ordinary skill in the art will understand that this convention generally means that it is interpreted in this way (e.g., "a system having at least one of A, B, or C" will include, but is not limited to, a system having A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.).
