Systems, methods, apparatuses, and computer program products for channel access for semi-static uplink (UL) resources are provided. One method may include receiving, at a user equipment, an indication of at least one of time portions of channel occupancy time (COT) where the user equipment can use a first type of channel access for configured uplink (CUL) transmission or time portions where a second type of channel access is required prior to the configured uplink (CUL) transmission. The method may then include, based on the received indication, determining a channel access mechanism to use when transmitting on a configured uplink (CUL) resource.

A method for a communication protocol that includes wideband access for low latency audio. A source device and a sink device establish a wireless communication link. The protocol for communicating via the wireless communication link includes a frame having a first deterministic portion and a second opportunistic portion. The source device transmits during the first deterministic portion of the frame, first data to the sink device. The source device determines whether a predetermined condition associated with the wireless communication link is satisfied. When the predetermined condition is satisfied, the source device transmits, during the second opportunistic portion of the frame, second data to the sink device.

Techniques discussed herein can facilitate autonomous user equipment beam failure recovery abort aspects. One example aspect is a baseband processor configured to perform operations including: establishing a connection with a downlink (DL) beam; detecting a beam failure of the DL beam; in response to the beam failure, executing at least one of: a beam failure recovery (BFR) procedure or a candidate beam detection (CBD) procedure; detecting a recovery abort condition while executing the at least one of: the BFR procedure or the CBD procedure; aborting the at least one of: the BFR procedure or the CBD procedure, in response to detecting that the recovery abort condition is satisfied; and maintaining the connection with the DL beam.

Aspects relate to the amount of shared bandwidth to be used for channel occupancy time (COT) sharing. An initiator device may use a clear channel assessment procedure to gain access to wireless communication resources for a COT that will be shared between the initiator device and a responder device. In some examples, the responder device may determine the shared bandwidth based on information that is implicit in a transmission from the initiator device. For example, the responder device may determine the shared bandwidth based at least in part on a bandwidth of a transmission from the initiator device.

There may be situations in which it is beneficial for a user equipment to switch between grant-free uplink wireless transmissions and grant-based uplink wireless transmissions. Systems and methods are disclosed that help facilitate grant-based and grant-free uplink wireless communications, and the switching between the two. For example, systems and methods for mitigating collision between a granted uplink wireless transmission and a grant-free uplink wireless transmission are disclosed herein.

A random access control method can be applied to electronic devices and include: determining, when a medium access control layer receives a beam failure instance indication sent by a physical layer, whether a count value of a beam failure indication counter is greater than or equal to a preset value; detecting, when the count value of the beam failure indication counter is greater than or equal to the preset value, whether the electronic device is currently performing a random access; triggering, when the electronic device is not currently performing the random access, a new random access. According to the embodiments of the present disclosure, the user device can be prevented from occupying resources for a contention free random access (CFRA) for a long time.
