Methods, systems, and devices for wireless communications at a user equipment (UE) are described. Techniques are described herein for performing out-of-order processing. The UE may receive a first downlink channel at a first time and a second downlink channel at a second time. The UE may determine that a priority of the second downlink channel is different (e.g., higher) than a priority of the first downlink channel. The UE may determine that a first uplink transmission associated with the first downlink channel is to be transmitted after a second uplink transmission associated with the second channel based on the different priorities. The UE may set one or more operations based on these determinations. In some cases, the UE may suspend processing the of the first downlink channel to process the second downlink channel.

Embodiments of the present disclosure provide a communication method and apparatus, and a device. The method includes: a first terminal device determining a first time period; and the first terminal device transmitting a first resource set to a second terminal device within the first time period, where the first resource set is used for the second terminal device to perform resource selection. The communication interference is reduced.

Uplink access in 5G and 6G is tightly controlled by the base station. Prior art procedures can impose access delays, such as waiting for a periodic scheduling request opportunity, which may be excessive for some user devices. Disclosed is a compact and responsive procedure for the base station to provide access to high-priority user devices first, and then low-priority user devices in a cascaded manner. The low-priority user devices are allocated to sections and, on a periodic schedule, can transmit a signal indicating which sections include at least one user device seeking access. Then the base station can provide a user poll region in which the ready user devices can submit their scheduling requests on pre-assigned subcarriers, but including only those sections that have at least one ready user devices. High-priority users are thus served first, while time and resources are saved by ignoring sections that have no ready users.

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.

Methods, media, and systems are provided for a priority-based multi-user (MU) multiple-input multiple-output (MIMO) pairing threshold for codebook beamforming. The methods, media, and systems identify a plurality of user device candidates for a user device pairing. A first user device of the plurality of user device candidates having a higher priority than another user device of the plurality of user device candidates is identified. A correlation of the first user device with a second user device of the plurality of user device candidates is determined to be below a threshold. Based on determining that the correlation is below the threshold, the first user device is paired with the second user device for sharing a resource.

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 to enable a user equipment (UE) to determine a rate-matching scheme or a feedback scheme for overlapping downlink transmission resources. A collision handling scheme may enable the UE to de-rate match a second, higher priority downlink shared channel independent of another rate-matching pattern or indicator for other shared channels, such as a first, overlapping downlink shared channel. The UE may determine to de-rate match the second channel around resources indicated within control signaling or higher-layer signaling associated with the second channel. The collision scheme may provide for the UE to generate an acknowledgement bit for feedback for one or more portions of the first channel that are preempted by the second channel and generate other feedback for non-preempted portions. A base station may keep track of preempted resources and may retransmit preempted portions of the first channel.
