A user equipment (UE) and base station may be configured to implementing trigger-based joint TX-RX sensing for channel access. In some aspects, the UE may monitor, via a receiver, for one or more transmissions from a first base station, detect, during the monitoring, interference associated with a pre-grant communication, the pre-grant communication associated with a future communication between a second base station a second user equipment, and transmit, via a transmitter, a reservation communication to the second base station in response to the pre-grant communication. In some aspects, the UE may receive the one or more communications from the first base station, without interference from the second base station, based on transmitting the reservation communication.

A method and apparatus for transmitting and receiving uplink control information. The method includes: determining a channel access type of an uplink control channel used for transmitting uplink control information by a terminal equipment; and detecting a channel according to the channel access type and transmitting the uplink control information to a network device after the channel is detected as being idle, or not detecting a channel according to the channel access type and transmitting the uplink control information to the network device. Hence, in some scenarios, uplink control information may be transmitted without detecting a channel, which may lower latency and improve transmission efficiency; and in some other scenarios, uplink control information may be transmitted after the channel is detected as being idle, which may avoid or lower interference and improve reliability of transmission.

The present disclosure generally relates to wireless communication. In some aspects, a user equipment (UE) may identify a collision between a first uplink transmission and a second uplink transmission, wherein the first uplink transmission is a high priority uplink transmission and the second uplink transmission is a low priority uplink transmission; and cancel the second uplink transmission based at least in part on a threshold delay period, wherein the threshold delay period is based at least in part on a UE processing capability and a minimum processing timeline capability, and wherein the second uplink transmission is canceled before a first overlapping symbol of the first uplink transmission and the second uplink transmission. Numerous other aspects are provided.

Methods, systems, and devices for wireless communications are described. A UE may perform a wireless sensing procedure, such as radar sensing, based on a sensing pattern defining one or more sensing signal burst occasions. A base station may transmit signaling including a request to suspend the wireless sensing procedure based on a resource collision, or scheduling conflict, between the one or more sensing signal burst occasions used for the wireless sensing procedure and one or more resources used for communications between the UE and the base station. The UE may determine to suspend the wireless sensing procedure or reject the data transmission during the resources that collide. The UE may selectively continue the wireless sensing procedure or pause the wireless sensing procedure based on the determining.

Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) to group transmissions into one or more groups, e.g., of various priority levels and/or types of transmissions. The UE may resolve collisions, e.g., according to one or more procedures described herein. The UE may transmit the transmissions according to the resolutions.

Disclosed are a method, an apparatus, and a system for transmitting a signal using multiple carriers. In detail, provided are a wireless communication apparatus including a communication module; and a processor, wherein the processor obtains a common back-off counter for a carrier set on which data is to be transmitted, wherein the carrier set includes at least one component carrier, performs back-off of each of the component carriers using the obtained common back-off counter, and simultaneously transmits data through at least one component carrier in which the back-off is completed and a wireless communication method using the same.

Provided by an embodiment of the present application are a method and device for determining a contention window, the method comprising: according to feedback information sent by a terminal device, a network device determining the length of a contention window (CW) used for channel detection, the feedback information comprising feedback information corresponding to a physical downlink shared channel (PDSCH) sent by the network device on a first carrier wave; according to the length of CW, the network device performing channel detection on the first carrier wave.

Adaptive energy detection (ED) threshold medium access is discussed based on deployment and traffic type. The network nodes sharing a shared communication network are configured with multiple discrete ED thresholds or a range of ED values. As a transmitting node prepares to attempt access to the shared communication spectrum, it identifies an access trigger condition within the network. Such a condition may include traffic type, deployment, or access conditions. In response to detecting an access trigger condition, the transmitting node may select an ED threshold associated with the access trigger condition. Alternatively, upon detection of the access trigger condition, the transmitting node may implement a random ED threshold from the candidate range of ED threshold values.

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for selecting a minimum measurement duration in listen-before-talk (LBT) sensing slots for high band unlicensed channel access. In some examples, a device may select a minimum sensing duration for an LBT procedure according to a sensing bandwidth or an energy threshold (such as an energy detection threshold or an energy power spectral density threshold), or both. As part of the LBT procedure, the device may measure or sense a wireless channel for at least the selected minimum sensing duration in each sensing slot of the LBT procedure. The device may selectively transmit on the wireless channel according to a result of the LBT procedure. For example, the device may either transmit or refrain from transmitting on the wireless channel depending on whether the device senses the wireless channel to be available.

This disclosure provides a transmission processing method, a terminal, and a control node. The method includes: when first transmission collides with second transmission, performing collision processing on the first transmission and the second transmission according to a collision processing policy, where at least one of the first transmission and the second transmission is transmission performed based on a sidelink, and transmission modes of the first transmission and the second transmission are different.
