A method can include negotiating a target wake time (TWT) with a TWT session period (TWT SP) duration and generating mask data that inhibits communications according to a second standard during at least a portion of TWT SP. A method can further include, by operation of second communication circuits, generating a communications mask from mask data received from WLAN circuits, in response to the timing signal, synchronizing the communications mask with the TWT SP, and in response to the communications mask, inhibiting communications according to the second standard during at least a portion of the TWT SP. Corresponding devices and systems are also disclosed.

This disclosure relates to techniques for supporting message mapping via time and/or frequency indexing. For example, these techniques may be applied to device-to-device wireless communication. For example, device to device discovery may use message mapping via frequency indexing. A portion of the payload of a message, such as a discovery message, may be offloaded to a frequency and/or time index. A receiving device may determine the offloaded portion of the payload based on the frequency and/or time (e.g., subcarrier and/or slot) used to transmit the message.

The present specification relates to a method by which a device performs data transmission or reception in a wireless communication system, comprising: performing an initial access operation with other devices; and transmitting first information (M−N) times and second information N times to the other devices, wherein M and N are respectively natural numbers, M is greater than N, and the first information and the second information are respectively the information related to timing adjustment, the first information has a value differing from that of the second information, and the data transmission or reception with the other devices is performed on the basis of a timing advance (TA) value, which is based on the average of all of the first information transmitted (M−N) times and the second information transmitted N times.

A method for performing wireless communication by a first device and a device supporting the same are provided. The method may comprise: selecting a synchronization source based on a sidelink synchronization priority, wherein the synchronization source includes at least one of a global navigation satellite system (GNSS), a base station, or a UE; obtaining synchronization based on the synchronization source; transmitting, to a second device, sidelink-synchronization signal block (S-SSB) block based on the obtained synchronization, wherein the S-SSB block includes a sidelink primary synchronization signal (S-PSS), a sidelink secondary synchronization signal (S-SSS) and a physical sidelink broadcast channel (PSBCH); receiving, from a base station, information related to a configured grant (CG) resource; and transmitting, to the second device, first sidelink data on a CG resource based on information related to the CG resource.

In an embodiment a method includes emitting at least one group of at least N+1 mutually temporally asynchronous synchronization signals from at least N+1 fixed emitting locations in a space, receiving the synchronization signals of the group by a mobile device and at at least one fixed receiving location in the space, determining a reception moment of each synchronization signal of the at least one group by the mobile device in a time base specific to the mobile device, determining a reception moment of the synchronization signals of the at least one group at the at least one receiving location in a time base specific to each receiving location, and determining a position of the mobile device in the space at a given moment based on the reception moments determined at the at least one receiving location, the reception moments determined by the mobile device, coordinates of the emitting locations in the space and a distance between each emitting location and the at least one receiving location.

This application provides a gateway handover method and an apparatus, to ensure the reliability of a gateway handover of a terminal device and reduce hardware overheads in a gateway handover process. The terminal device receives a synchronization signal/PBCH (physical broadcast channel) block (SSB) from a network device through a service link. The SSB includes an SSB of a source gateway and an SSB of at least one candidate target gateway. The terminal device obtains a measurement value of channel quality corresponding to the SSB of the at least one candidate target gateway, and sends a measurement result to the network device. The network device forwards the measurement result to the source gateway, which determines, based on the measurement result, whether to hand over the terminal device from the source gateway to one of the at least one candidate target gateway.

Examples of the present disclosure relate to a data transmission method and apparatus, and a communication device. The method includes: during a first time length prior to a start moment of a measurement gap, receiving Downlink Control Information (DCI); in response to determining that the DCI schedules transmission of a predetermined service, starting a first timer; during a period when the first timer is running, keeping downlink communication with a serving cell, where the downlink communication includes transmitting the predetermined service.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a base station capable of performing medium access control (MAC) based transmission configuration indication (TCI) switching. The UE may deactivate an autonomous beam switching mode based at least in part on the base station being capable of performing MAC based TCI switching. Numerous other aspects are described.

Methods, systems, and devices for wireless communications are described. A first base station may communicate during asynchronous slots in accordance with a set of communication parameters determined from a handshake procedure performed with a second base station. For example, based on a change to a slot type of a slot to an asynchronous slot, the first base station and the second base station may perform the handshake procedure to determine the set of communication parameters and may communicate one or more messages during the slot in accordance with the set of communication parameters. Additionally, or alternatively, a user equipment (UE) may transmit a sounding reference signal (SRS) associated with a transmission configuration indicator (TCI) state based on a slot type of a first slot in which the UE transmits the SRS and a reference signal received in a second slot having the slot type.

A digitizing apparatus for transmitting electromagnetic telemetry signals to facilitate drilling operations comprises a local receiver and one or more remote transmitters. A method uses the remote transmitter to measure an electric potential between a pair of ground stakes that are positioned at some distance away from the local receiver. The local receiver is coupled to a surface receiver that is located at or near a drilling rig. The remote transmitter converts the electric potential into a digital signal and transmits the digital signal wirelessly to the local receiver. The local receiver then converts the digital signal into an analog signal that is provided to the surface receiver for processing. The remote transmitter and local receiver may comprise GPS clocks to synchronize the signals to maintain a constant phase shift.
