A user equipment (UE) is described. The UE includes circuitry configured to determine that a physical uplink control channel (PUCCH) with low priority (LP) carrying a LP hybrid automatic repeat request-acknowledgement (HARQ-ACK) overlaps with more than one high priority (HP) PUCCHs carrying HP HARQ-ACKs. The circuitry is also configured to, when only radio resource control (RRC) configuration is used for enabling and disabling uplink control information (UCI) with different priorities, allow the LP HARQ-ACK to multiplex with the HP HARQ-ACK of the first overlapping HP PUCCH only.

This disclosure provides systems, methods, and devices for wireless communication that support resolution of uplink (UL) transmission overlap of communication types having different priorities. In some implementations, a method of wireless communication includes determining, at a user equipment (UE), that a first scheduled UL transmission corresponding to a first communication type having a first priority overlaps with a second scheduled UL transmission corresponding to a second communication type having a second priority. The first priority is higher than the second priority. The method also includes multiplexing at least a portion of the first scheduled UL transmission with at least a portion of the second scheduled UL transmission to generate a third UL transmission. The method further includes transmitting, from the UE to a base station, the third UL transmission. Other aspects and features are also claimed and described.

Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive control signaling indicating a semi-persistent scheduling configuration that identifies a plurality of resource occasions each comprising a plurality of resources of a sidelink channel allocated to the first UE for sidelink communication. The UE may identify a rescheduling configuration for scheduling transmission of a first message that has a possible conflict with transmission of a second message during a first resource of the plurality of resources of a first resource occasion of the plurality of resource occasions, the first message having a different priority than the second message. The UE may transmit the second message during the first resource occasion and may transmit the first message via the sidelink channel in accordance with the rescheduling configuration.

Some embodiments include an apparatus and method for enabling concurrent peer-to-peer (P2P) communications via a scheduled resource unit (RU) allocated by an access point (AP). For example, the AP may use a trigger frame to schedule uplink (UL) multi-user (MU) access for a first station of a plurality of stations by allocating an RU to the first station. Instead of using the allocated RU for UL infrastructure communications with the AP, the first station may utilize the allocated RU for a P2P communications with a second station. In some embodiments the AP facilitates RU utilization for P2P communications between stations. In some embodiments, the first station uses the allocated RU and the AP may be unaware of the P2P communications.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive one or more messages indicative of uplink semi-persistent scheduling (SPS) resources and downlink SPS resources allocated to the UE, the uplink SPS resources and the downlink SPS resources being within a frequency band used for full duplex communications by the UE. The UE may modify parameters associated with the full duplex communications on the uplink SPS resources, the downlink SPS resources, or both, based at least in part on instances of the uplink SPS resources at least partially overlapping in time with instances of the downlink SPS resources. The UE may apply the one or more parameters, after modification, to transmission of uplink communications over the instances of the uplink SPS resources, reception of downlink communications over the instances of the downlink SPS resources, or both.

Aspects relate to techniques for facilitating sidelink cancellation. A network entity, such as a base station, may schedule a sidelink transmission between a transmitting wireless communication device and a receiving wireless communication device and transmit scheduling information for the sidelink transmission to at least the transmitting wireless communication device. The network entity may further transmit control information including a cancellation indication to at least the transmitting UE. The cancellation indication may indicate at least an overlap between a portion of the resources allocated to the sidelink transmission and an additional transmission. Based on the cancellation indication, the transmitting wireless communication device may modify the sidelink transmission.

Aspects relate to techniques for enhancing sidelink scheduling information to include a priority assigned to a sidelink transmission. For example, a transmitting wireless communication device may receive sidelink scheduling information scheduling a sidelink transmission from a transmitting wireless communication device to a receiving wireless communication device. The sidelink scheduling information may further include a priority indicator associated with the sidelink transmission. The transmitting wireless communication device may then transmit the sidelink transmission to the receiving wireless communication device based on the scheduling information. The priority indicator may further facilitate hybrid automatic repeat request (HARQ) codebook construction on the sidelink and uplink for the transmission of acknowledgement information of the sidelink transmission.

Aspects relate techniques for facilitating resumption of a sidelink transmission after cancellation of the sidelink transmission within resources that overlap with an additional transmission. A transmitting wireless communication device may receive control information from a network entity including a cancellation indication indicating overlapping resources between the resources scheduled for the sidelink transmission and resources scheduled for the additional transmission. Based on the cancellation indication, the transmitting wireless communication device may cancel the sidelink transmission within cancelled resources including at least the overlapping resources and transmit the sidelink transmission via remaining resources of the scheduled resources for the sidelink transmission outside of the cancelled resources.

A method for concurrent execution of multiple protocols using a single radio of a wireless communication device is provided that includes receiving, in a radio command scheduler, a first radio command from a first protocol stack of a plurality of protocol states executing on the wireless communication device, determining a scheduling policy for the first radio command based on a current state of each protocol stack of the plurality of protocol stacks, and scheduling the first radio command in a radio command queue for the radio based on the scheduling policy, wherein the radio command scheduler uses the radio command queue to schedule radio commands received from the plurality of protocol stacks.

A method for selecting a resource in a sidelink communication, includes: determining at least one first time unit that satisfies a sensing condition within a set of time units for sidelink communication resources, wherein the set of time units includes one or a plurality of first time units; and determining a resource for transmitting based on a resource in the at least one first time unit.
