Methods and systems are disclosed for resource management on Sidelink for vehicle to everything (V2X) scenarios. Example methods and systems for a Resource Structure on Sidelink are disclosed. Control and data channels may be Frequency Division Multiplexed (FDMed) or Time Division Multiplexed (TDMed) with an Orthogonal Frequency Division Multiplexing (OFDM) waveform. Example methods and systems for a Resource Configuration on Sidelink are disclosed. The resource configuration may be statically configured or may be locally configured. Example methods and systems for Assisted Resource Allocation are disclosed. Assisted Sensing may be performed by a group lead or RSU and local scheduling may be performed by a group lead or RSU.

Resource management for 5G eV2X

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network node, a first indication, associated with a sidelink communication, of at least one of whether sidelink carrier aggregation is supported or a first one or more component carriers associated with the sidelink communication. The UE may receive, from the network node based on transmitting the indication, a second indication that a transmission associated with the sidelink communication is to be duplicated for multiple component carriers. The UE may transmit, based on the second indication, the sidelink communication via each of a plurality of component carriers that include at least one component carrier from the first one or more component carriers. Numerous other aspects are provided.

Sidelink carrier aggregation

Methods, systems, and devices for wireless communication are described. In some cases, a first user equipment (UE) may perform a listen-before-talk (LBT) procedure to identify a channel occupancy time (COT). The COT may include some slots for transmitting a sidelink message and some sidelink synchronization signal block (S-SSB) slots for transmitting S-SSBs. In some examples, to fill a gap created by the S-SSB slots within the COT and thus maintain the COT across the S-SSB slots, the first UE or the second UE may transmit some signaling to provide transmissions in the S-SSB slots. For example, the first UE may transmit a padding signal, the second UE may transmit S-SSBs, or the UEs may use a gap control procedure. Upon filling the gap, the first UE may transmit a sidelink message to the second UE in slots of the COT excluding the S-SSB slots.

Maintaining channel occupancy time across sidelink synchronization signal block slots in unlicensed sidelink

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may start a sidelink bandwidth part (BWP) timer with a duration that is based at least in part on a timing of a sidelink discontinuous reception active state of the first UE. The first UE may switch to a first sidelink BWP for the duration of the sidelink BWP timer. Numerous other aspects are described.

Sidelink bandwidth part timer based on active state

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus of a user equipment (UE) may transmit, over an unlicensed carrier, an initial transmission of a transport block (TB) satisfying a condition and an indication that a retransmission of the TB will be communicated over a licensed carrier. The apparatus may retransmit the TB over the licensed carrier based at least in part on a failure of the transmission of the TB over the unlicensed carrier. Numerous other aspects are described.

Unlicensed-licensed cross-carrier retransmission

The apparatus may be a first wireless device configured to receive a first indication that a second wireless device associated with the first wireless device and a network device is classified as providing data of a first type. The apparatus may further be configured to receive a first set of data elements from the second wireless device. The apparatus may be configured to identify, based on the first set of data elements and a second set of data elements available at the first wireless device, that the classification of the second wireless device may be inaccurate and transmit, based on the identification that the classification of the second wireless device may be inaccurate, at least one of a second indication for the second wireless device to transmit a re-evaluation request or a third indication to the second wireless device to terminate a communication session with the first wireless device.

Mitigating the effects of rogue actors in vehicle-to-vehicle perceptive wireless communications

UEs' mobility may have a significant impact on sidelink communications and Uu mobility procedures of UEs participating in SL communication or SL Group Communication. Methods devised to optimize handover procedures, cell reselection procedures, and transition to RRC_IDLE and RRC_INACTIVE for UEs with ongoing SL communications. Methods are disclosed herein for PLMN selection for UEs requiring sidelink communication or with active sidelink communication, as well as, methods to provide priority-based resource allocation while using exceptional transmit resource pools. Also, provided are SL group management procedures to deal with impacts of UE mobility.

NR V2X mobility

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may configure a discontinuous reception (DRX) cycle of the first UE for a sidelink connection with a second UE. The UE may identify a mode that specifies whether the first UE is to receive a communication outside of an on duration of the DRX cycle if the on duration is extended due to receiving sidelink control information (SCI) reserving a resource outside of the on duration. The UE may communicate in accordance with the mode. Numerous other aspects are described.

Power consumption optimization under discontinuous reception

Methods, systems, and devices for wireless communications are described. Wireless devices may be configured to support techniques for bi-directional discontinuous reception (DRX) alignment and centralized DRX alignment. In the context of bi-directional DRX alignment, DRX configurations at two respective user equipments (UEs) are first established in a first direction, and then DRX configurations are then established in the reverse direction based on the previously-established DRX configurations. In particular, DRX configurations in the reverse direction may be selected such that the Uu and sidelink DRX configurations are aligned at the respective UEs and across the UEs. Comparatively, in the context of centralized DRX alignment, a master base station receives 'candidate' Uu and sidelink DRX configurations for multiple UEs, and selects Uu and sidelink DRX configurations for each UE from the sets of candidate DRX configurations in order to ensure DRX alignment across the respective UEs.

Discontinuous reception alignment for wireless communications

Aspects described herein relate to sidelink transmissions. In an example, a first user equipment (UE) may receive, from a network entity, a first sidelink grant for a transmission between the first UE and a second UE; communicate the transmission according to the first sidelink grant to the second UE; determine initiation of a sidelink round trip timer subsequent to communicating the transmission to the second UE; and initiate an inactive mode for the first UE based on a second grant not being received from the network entity before completion of a duration of a sidelink retransmission timer that was initiated upon completion of a duration of the sidelink round trip timer, the first UE being configured out of an ON duration of a discontinuous reception (DRX) cycle, and an inactivity timer expiring before completion of the duration of the sidelink retransmission timer.

Scheduling operation with mode-1 scheduling in sidelink and sidelink unlicensed operations

A subscriber issues a message to a resource host to request subscription to multiple resources. This message may indicate identifiers of these resources, event notification criteria for each individual resource and define cross-resource notification criteria such as time window type and time window size. The resource host issues cross-resource notifications to the subscriber or its designated notification targets when expected changes on the target resources occur within a time window.

Cross-resource subscription for M2M service layer

Methods, systems, and devices for wireless communications are described. Multiple transmitting user equipments (UEs) may send sidelink data transmissions. Receiving sidelink UEs may map sidelink feedback interlaces corresponding to detected sidelink data transmissions to sidelink feedback resources of a common sidelink feedback symbol according to an interlace mapping rule (e.g., defining which contiguous or non-contiguous frequency resources the UE is to use for transmitting sidelink feedback for the received sidelink data messages). The receiving UEs may map one or more replicas of initial interlaces of sidelink feedback resources to additional available resources of the sidelink feedback resources in the common feedback symbol.

Interlaced feedback for sidelink communications via unlicensed channels

Blind coverage for wireless devices is enhanced varying one or more transmission characteristics of a repeated transmission sent or received by apparatuses, where the repeated transmission includes, for example a Physical Downlink Shared CHannel (PDSCH) and/or a Physical Uplink Shared CHannel (PUSCH) transmissions. Varied characteristics may include a start time for each repetition, a duration for each repetition, a start frequency for each repetition, a bandwidth of each repetition, a number of repetitions for each subframe, and/or a number of repetitions for each slot. Repetitions may be within a Bandwidth Part (BWP) or span multiple BWPs. Repetitions may vary from one to another in start time, start frequency, duration, bandwidth, and slot and subframe patterns. Higher level signalling, such as Radio Resource Control (RRC) signalling may be used to control the inclusion or omission of a DeModulation Reference Signal (DMRS) in repeated transmissions.

Coverage enhancement for reduced capability new radio devices

Methods, devices, and systems related to serving gateway extensions for inter-system mobility in integrated small Cell and WiFi networks. An SGW may be extended into a common intermediate gateway for both LTE and WiFi access. A GTP-based 'SI a' interface between a TWAN and an SGW is introduced. The STa interface between TWAN andGPP AAA server/proxy is extended to enable selection of an SGW for establishment of the disclosed Sla interface. The extended SGW and protocols may be used to optimize inter-system mobility between LTE small cells and trusted WiFi. SGW and PDN Gateway (PGW) functionality is disclosed to support GTP-based IP Flow mobility via multi-access (LTE and WiFi) connectivity to the same packet data network (PDN). Non-access stratum (NAS), EAP, and GTP-C protocols may also be extended to include a “multi-connection” indication in addition to existing “handover” indication.

Serving gateway extensions for inter-system mobility

Switching between Orthogonal Multiple Access (OMA) and Non-Orthogonal Multiple Access (NOMA) modes of a user equipment (UE) can be determined and indicated by a gNB to a UE at an RRC connected state using one or more of the following schemes: at an RRC (Radio Resource Control) layer with an RRC configuration message, at a MAC (Medium Access Control) layer with MAC CE (MAC control element) signaling, at a PHY (Physical) layer with DCI (Downlink Control Information) signaling, jointly with RRC configuration and DCI signaling, and/or jointly with RRC configuration and MAC CE signaling. The OMA or NOMA mode that the UE operates after the transition may be requested by the UE, indicated by the gNB, and/or may be based on one or more rules for OMA-NOMA switching.
