Abstract: Certain aspects of the present disclosure provide techniques for user equipment (UE) autonomous sidelink resource selection. A method that may be performed by a UE includes performing autonomous sidelink resource selection. The selection includes excluding resources, from a first resource set, associated with transmissions at a signal strength above a signal strength threshold to form a second resource set. The selection includes determining a resource amount in the second resource set is at or above a threshold percentage of a resource amount in the first resource set. The selection includes excluding, from the second resource set, resources associated with physical sidelink control channels (PSCCHs) without excluding resources associated with physical sidelink shared channels associated with the PSCCHs to form a third resource set. The selection includes randomly selecting resources for a PSCCH transmission from the third resource set. The method includes sending the PSCCH transmission using the randomly selected resources.

Abstract: A method includes cellular vehicle-to-everything (CV2X) allocation collision detection and reporting. An allocation collision detection module detects control channel allocations from transmitting user equipments (UEs) in each time period of a group of time periods. A quantity of detected control channel allocations is determined in each time period. A report is then built and transmitted to at least one of the transmitting UEs. The report indicates collisions in each time period, based on the quantity and a location of the detected control channels in each time period, as well as based on a type of UE interface.

Abstract: Certain aspects of the present disclosure provide techniques for cyclic shift selection for physical sidelink control channel retransmissions. A method that may be performed by a first user equipment (UE) includes monitoring one or more sidelink control information (SCI) transmissions from one or more second UEs. The method generally includes determining, based on the one or more SCI, whether one or more collisions occur between one or more retransmissions of the one or more SCI transmissions by the one or more second UEs and a scheduled SCI transmission by the first UE. The method generally includes selecting a cyclic shift to use for the scheduled SCI transmission by the first UE based at least on the determination.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a network entity, control information indicating a first set of resource elements (REs) allocated for a tone reservation signal based on a channel frequency response. The UE and the network entity may determine a second set of REs for the tone reservation signal on the first set of REs and application of a rule. The rule may pertain to contention resolution between REs allocated for tone reservation signaling and REs allocated to a channel used for downlink signaling. The UE may receive both the tone reservation signal and a downlink signal, where the tone reservation signal is received in accordance with the second set of REs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first portion of downlink control information (DCI), via one or more control channel element resources, that includes information associated with a second portion of the DCI in a physical shared channel. The UE may obtain the second portion of the DCI via the physical shared channel based at least in part on the information. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a radio unit (RU) may receive, from a distributed unit (DU), an indication of a service level based operation mode, from a set of multiple candidate service level based operation modes, to use for transmitting or receiving a front haul communication. The RU may transmit or receive the front haul communication having a level of layer 1 processing that is based at least in part on the service level based operation mode. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for prioritized signaling via a functional application programming interface (FAPI). A method for conveying uplink (UL) payload may include receiving, at a physical (PHY) layer, a UL payload from one or more user equipments (UEs) and delivering different segments associated with the UL payload, to a medium access control (MAC) layer, in different messages via a functional application platform interface (FAPI). According to certain aspects, the different segments may carry UL payload with different priorities, and segments with higher priority UL payload may be delivered, to the MAC layer, prior to segments with lower priority UL payload.

Abstract: A method of wireless communication of a wireless device in a C-V2X connection may include: determining a first WBEE of a symbol at a first bandwidth, the symbol being associated with no expected C-V2X transmissions, determining a second WBEE of the symbol at a second bandwidth, and identifying an interference based on the first WBEE and the second WBEE. The method may also include notifying an operator of the wireless device about the identified interference.
