A method for transmitting data by a communications device in a wireless telecommunications network comprising a base station and a non-terrestrial network part, the method comprising determining that data is to be transmitted by the communications device to the base station via the non-terrestrial part, in response to the determining, selecting a random access preamble from a group of random access preambles, each of the random access preambles of the group being associated with one or more resource pools of communications resources for transmitting data, and transmitting the selected random access preamble.

Provided are an electronic device that performs ranging by using an ultra wide-band (UWB) communication scheme and an operation method of the electronic device. The operation method of the first electronic device includes transmitting a first ranging control message (RCM) comprising interval information to a second electronic device, determining a first time to transmit a second RCM based on the interval information, determining a first RCM timing window (RTW) based on the first time, transmitting the second RCM to the second electronic device in the first RTW, and transmitting a third RCM at a second time in a second RTW, based on a failure to receive a response message corresponding to the second RCM within a specific time period in the first RTW, wherein the second time is a random time point in the second RTW.

A communication method includes receiving a first message from a first network device, and sending a second message to a terminal device. The first message includes random access related information. The second message indicates a first random access type that is usable in a random access procedure. The first random access type is a 2-step random access channel (RACH) or a 4-step RACH. The random access related information includes at least one of random access indication information useable to indicate the first random access type, random access capability information including information of a random access type supported by the terminal device, random access mode information useable to indicate a contention-based random access mode or contention-free random access mode in the random access procedure, an early downlink-data transmission indication useable to indicate to transmit a downlink data packet in the random access procedure, or a size of the downlink data packet.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of a configuration for multiple sets of prioritization parameters for a random access channel (RACH) procedure. A first set of prioritization parameters of the multiple sets of prioritization parameters may be associated with a higher priority network slice than the other sets of prioritization parameters (e.g., than the remaining sets of prioritization parameters). The UE may detect a trigger to perform a RACH procedure and select the first set of prioritization parameters for the RACH procedure based on the first set of prioritization parameters being associated with the higher priority network slice. The UE may perform the RACH procedure for the network slice according to the first set of prioritization parameters.

A method, computer-readable media and system for providing Random Access Channel (RACH) response preamble prioritization are presented. In one embodiment a method includes receiving, from a RACH receiver at a Preamble Prioritization Element (PPE), a list of detected preambles from a plurality of User Equipment (UE) devices, the preambles having a configured priority for different preamble groups; providing, by the PPE, an ordered prioritized list of the detected preambles; and forwarding, by the PPE to a RACH response element, a predetermined number of detected preambles from the ordered prioritized list.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a wakeup signal (WUS) associated with a discontinuous reception (DRX) ON duration; determine that a grant was not detected in the DRX ON duration; and perform an action based at least in part on whether the WUS is specific to the UE or is associated with a group of UEs. Numerous other aspects are provided.

Provided are a method of access control and a device supporting the method. According to an embodiment of the present disclosure, the method includes: selecting access information for an access to a cell; determining channel access priority class (CAPC) mapped to the selected access information; performing a listen-before-talk (LBT) procedure based on the CAPC; and transmitting an access request to the cell, when a result of the LBT is successful. According to another embodiment of the present disclosure, the method includes: determining channel access priority class (CAPC) mapped to a control message; performing a listen-before-talk (LBT) procedure based on the CAPC; and transmitting the control message, when a result of the LBT is successful.

A method and apparatus for communication in a network of WLAN overlapping basic service set (OBSS) are disclosed. A station or an access point may indicate its interference reporting and inter-BSS coordination capabilities in a message. At least one of quality of service (QoS) settings, transmission opportunity (TXOP), restricted access window (RAW) or beacon subinterval schedules, or traffic indication map (TIM) or uplink access window assignment may be coordinated. The station may receive a request for interference measurements on the basic service set (BSS) of the station or neighboring BSSs that the station can overhear. The station may transmit an interference measurement report to an access point. The coordination may be performed based on the interference measurement report. Furthermore, STAs may transmit channel or sector preferences to APs and receive channel or sector assignments.

Configured grant (CG) channel occupancy time (COT) sharing procedure is disclosed. A user equipment (UE) sharing a COT may indicate in the uplink control indicator (UCI) the remaining COT duration, an offset indication identifying where the uplink transmission is expected to end, and a channel access priority class (CAPC) which may be used by the base station to determine which type of data may be included in downlink transmissions in the shared COT. Where the energy detection (ED) threshold has not been configured for COT sharing, the UE may reduce the information included in the UCI. The base station may alternatively configured which information for the UE to include in the UCI for potential COT sharing. The COT sharing information may further be compressed by coding such information into tables or leveraging knowledge of transmission characteristics, such as configured end points.

A method by which a base station transmits a downlink channel in a wireless communication system comprises the steps of: selecting a channel access priority class (CAPC) from among a plurality of CAPCs preset for the transmission of a downlink channel; performing channel access on a first channel on the basis of a parameter set in response to the CAPC; and transmitting, to a terminal, one or more physical downlink control channels (PDCCHs) on the first channel.
