Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive information indicating a reference signal resource associated with detecting cross-link interference associated with transmitting a random access channel (RACH) message on full duplex resources. The first UE may transmit a RACH message on a selected RACH occasion, wherein the selected RACH occasion is selected based at least in part on whether a reference signal transmitted by a neighbor UE of the first UE has been detected in association with the selected RACH occasion. Numerous other aspects are described.

The present disclosure relates to methods and apparatuses for handling collisions. A method includes receiving at a first communication equipment first scheduling information; determining whether there is a transmission resource collision of a first TB and a second TB; and storing the first TB or the second TB for transmission if the collision is determined.

Disclosed are a method for transmitting, by a terminal, a sounding reference signal to a base station without a physical uplink shard channel in a licensed assisted access (LAA) system in which a base station or a terminal performs listen-before-talk (LBT)-based signal transmission, and an apparatus supporting the same.

This invention discloses a method for controlling a wireless communication device to transmit data packets. The method includes steps of: transmitting data packets; counting retry times of data packets in a predetermined time period and generating a result accordingly; comparing said result with a predetermined value and generating a comparison result accordingly; and reducing transmission time of data packets according to said comparison result.

A wireless device transmit a first message comprising a first preamble and a first transport block. The first transport block comprises a contention resolution identifier of the wireless device. The wireless device receive a first random access response to the first message. The first random access response comprises the contention resolution identifier. The wireless device starts a first time window in response to receiving the first random access response. The wireless device monitor, during the first time window, a downlink channel for a second random access response to the first message. The wireless device determines a failure to receive the second random access response during the first time window. The wireless device transmits a second message comprising a second preamble in response to the failure.

Enhanced techniques may be used for identifying and reporting collision-based scenarios. In one example, a wireless modem measures a number of signals received from a number of devices that are located on the same chip as the wireless modem when a physical link between the wireless modem and an accelerometer is broken, the accelerometer is inoperable, or a combination thereof. In the event of a collision event, the wireless modem may use the measured signals to determine that the collision event has occurred and may transmit an indication of the collision event. For instance, the wireless modem may use signals from an audio sensor, a motion sensor, a global navigation satellite system (GNSS), or the like.

Provided are a method for random access, a terminal device and a network device. The method includes a terminal device sending, to a network device, a preamble and a cell radio network temporary identifier media access control control element (C-RNTI MAC CE), wherein the C-RNTI MAC CE includes a C-RNTI; the terminal device performing blind detection on a physical downlink control channel (PDCCH) scrambled by the C-RNTI; and the terminal device determining, according to a blind detection result of the C-RNTI, whether a contention-collision in a two-step random access procedure has been resolved.

The implementations of the present application provide a random access method and apparatus, a user equipment (UE), and a network device. The method comprises: a UE sends a first message to a network device; the UE receives a second message sent by the network device, the second message being used for responding to the first messages of one or more UEs, and the second message comprising at least one of: UE conflict resolution identification information, a dedicated radio network temporary identifier (RNTI), uplink timing advance information, and uplink scheduling information.

An uplink transmission method and device, a computer readable storage medium and a terminal are provided. The method includes: when an uplink procedure starts, starting a corresponding timer; and when a timing duration of the timer has reached a preset timing duration, and the uplink procedure is unsuccessful, terminating the uplink procedure and triggering another procedure. In this way, uplink transmission can be performed when LBT fails multiple times. Besides, another procedure is triggered when the uplink procedure is terminated, which may shorten a duration of the uplink procedure, and avoid the increase of delay of the uplink procedure.

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.
