Abstract: Aspects of a methods, apparatus, and computer-readable medium for wireless communication at a wireless device are provided herein. The wireless device may receive a configuration for a resource pool for sidelink communication, the resource pool having a plurality of physical resource blocks (PRBs) including a first set of PRBs that are grouped in one or more sub-channels, each sub-channel having an equal number of PRBs, and a second set of PRBs that are not in the one or more sub-channels having the equal number of PRBs. The apparatus may transmit in the second set of PRBs. The second set of PRBs may not be monitored by a receiving device.

Abstract: A method detecting allocation collisions from transmitting user equipments (UEs) in sidelink channel resources. The colliding allocations are detected and the quantity of allocation collisions is determined. A collision report is transmitted to other sidelink UEs within the coverage zone. The collision report or collision notification provides an indication of sidelink resources having identified colliding allocations. The identified allocation collisions may be pruned to remove potentially intentional collisions before collision report transmission.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support communications. For example, a wireless communications system may support New Radio (NR) cellular-vehicle to everything (C-V2X) communication. In some examples, a user equipment (UE) may receive a sidelink control channel for a sidelink transmission on a first set of symbols of a time slot (e.g., the first two or three symbols of a time slot). The UE may decode the sidelink control channel and disable one or more radio frequency (RF) components associated with processing the sidelink transmission on a second set of symbols of the time slot based on decoding the sidelink control channel. For example, the UE may disable one or more RF components if the UE determines the sidelink control channel is decoded unsuccessfully.

Abstract: Device-to-device operations are scheduled based on receive and transmit pools that may have a conflict in time domain. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus for resolving time domain conflict in device-to-device communication are provided. The apparatus may compute a first block rate metric for a first device-to-device communication on a first frequency and a second block rate metric for a second device-to-device communication on a second frequency. The apparatus may detect a time-domain conflict between the first device-to-device communication on the first frequency and the second device-to-device communication on the second frequency. The apparatus may prioritize the first device-to-device communication on the first frequency and the second device-to-device communication on the second frequency based on the first block rate metric and the second block rate metric.

Abstract: Methods and devices are disclosed for enabling improved performance on a multi-subscriber identification module (multi-SIM) wireless communication device. The wireless communication device may detect transmit activity on a modem stack associated with the first SIM, and detect a communication activity scheduled on a modem stack associated with the second SIM having a higher priority. If the transmit activity on the modem stack of the first SIM will impede the communication activity, the wireless device may identify subframes on the modem stack associated with the first SIM that overlap in time with the communication activity and for each identified subframe, blank symbols that conflict with the communication activity to develop a partially blanked subframe. The partially blanked subframe may be transmitted according to a blanking policy.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. A user equipment (UE) may configure a first initial set of maximum transmit powers for a first subscriber module. The UE may configure a second initial set of maximum transmit powers for a second subscriber module. The UE may configure a first maximum transmit power associated with a first connection for the first subscriber module. The UE may configure, independently of the configuration of the first maximum transmit power, a second maximum transmit power associated with the second connection. The UE may transmit based at least in part on at least one of the first maximum transmit power or the second maximum transmit power. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain one or more parameters associated with a dual subscriber operation of the UE that includes communicating using a first subscriber entity and a second subscriber entity. The UE may transmit one or more uplink communications via one or more of the first subscriber entity or the second subscriber entity using a coexistence management configuration that is based at least in part on the one or more parameters. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and another device (e.g., another UE) may transmit messages on a shared channel accessed in a half-duplex manner (e.g., within a vehicle-to-everything (V2X) network). The UE and the other device may transmit messages on semi-persistently scheduled (SPS) resources. A message of the UE and a transmission of the other device may collide (e.g., be transmitted in the same subframe). The UE may employ muting and measuring, in which the UE may refrain from transmitting on a SPS resource and may detect the transmission of the other device. Upon detection of other transmissions, the UE may perform resource reselection. During resource selection or resource reselection, the UE may exclude an entire subframe of candidate resources if one of the candidate resources of the subframe is mapped to a resource associated with a transmission from another device.

Abstract: Certain aspects of the present disclosure provide techniques for sidelink (SL) channel selection coordination. A method that may be performed by a user equipment (UE) includes measuring, during a time period shorter than one slot, a channel condition of at least one first channel in a sidelink (SL) frequency band. The method further includes transmitting a signal on the at least one first channel or a second channel of the SL frequency band, wherein the at least one first channel or the second channel is chosen based on the channel condition.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes communicating control signaling scheduling a sidelink transmission via a physical sidelink channel, receiving, by a first user equipment (UE), the sidelink transmission including one or more reference signals from a second UE via the physical sidelink channel based on the control signaling, and monitoring the physical sidelink channel based on time synchronization, frequency synchronization, or both, determined using the one or more reference signals.
