Some embodiments of the present disclosure provide a method for time synchronization, a method for broadcast setting, a chip, an electronic device, and a storage medium. In the present disclosure, time synchronization information is received, wherein the time synchronization information includes a first count value N of at least one connection event at a synchronizing end and a first time, and the first time refers to a time of occurrence of an N.sup.th connection event (101); a second count value K of the at least one connection event and a second time are determined according to at least the first count value N and the first time, wherein the second time refers to a time of occurrence of a K.sup.th connection event, and both N and K are natural numbers (102); and time synchronization is performed based on the second time in response to occurrence of the K.sup.th connection event (103).

Apparatus and methods for S-SSB transmission are provided. In an aspect, an S-SSS symbol is followed by a gap symbol. In another aspect, a first PSBCH symbol is followed by an S-SSS symbol. In a further aspect, the same MPR is used for the entire S-SSB, thus reducing/mitigating transient periods. For example, the S-SSS symbols in the S-SSB may be selected from a set of sequences having the same MPR as the S-PSS symbols. Alternatively, the MPR of the entire S-SSB may be selected based on a sequence ID of an S-SSS. In an aspect, additional symbols may be configured in the S-SSB to compensate for power reduction.

A channel detection method and apparatus, a device and a user equipment are disclosed. The method includes: receiving, by a UE, a paging indication signal transmitted by a network device, where the paging indication signal is used for instructing the UE whether to detect a paging downlink control channel in K POs, the K POs are K POs after the paging indication signal is received, and K is a positive integer.

A satellite communication system communicates via a communication satellite using one of a plurality of portable station devices as a master station device and another portable station device as a slave station device. The master station device transmits a first control signal for the slave station device to establish synchronization. The master station device determines that the slave station device is in a communicable state by a second control signal received from the slave station device that has received the first control signal and established synchronization. The master station device selects one of at least one slave station devices in a communicable state and transmits a third control signal for instructing start of transmission of a communication signal to the selected slave station device and the subject device. Due to this, it is possible to connect a channel between portable station devices without the intervention of a control station device or a regulation station device.

Apparatus, methods, and computer-readable media for facilitating autonomous synchronization are disclosed herein. For example, a UE may be configured to perform an initial synchronization directly to PSCCH and PSSCH when other synchronization sources, such as GNSS, a base station, and/or SLSS, are unavailable. An example method for wireless communication at a user equipment includes receiving a PSCCH. The example method also includes performing an initial synchronization based on the PSCCH. In some examples, the method may also include receiving a PSSCH, and determining a logical subframe number modulo 10 based on the PSSCH. The logical subframe number modulo 10 may correspond to a sequence seed.

A measurement configuration method, a terminal, and a network side device are provided. The measurement configuration method is performed by the terminal and includes: receiving indication information transmitted by a first network side device, where the indication information is used to indicate a signal that changes in a target cell; and performing measurement or synchronization based on the signal that changes, where the target cell includes a serving cell or a neighboring cell, and the signal that changes includes at least one of a reference signal or a synchronization signal.

Embodiments of this application disclose a synchronization signal block determining method and a related apparatus. The method includes: A terminal device detects a first synchronization signal block (SSB); the terminal device determines a second SSB based on the first SSB, where a frequency domain position of the first SSB and a frequency domain position of the second SSB are within a preset bandwidth, or a difference between frequency domain positions of the first SSB and the second SSB is a preset value. The second SSB may be considered as a backup SSB for the first SSB.

The application proposes a method for wireless data reception and a wireless device, adaptable for the wireless device to receive data from an access point. Firstly, a transceiver of the wireless device is switched on at the target beacon transmission time. Thereafter, a first portion of a beacon is received, wherein a length of the first portion is less than a complete length of the entire beacon, and the first portion comprises a time stamp and a TIM. Finally, it is determined whether a data packet needs to be received according to the TIM. If it is determined that there is no data packet to receive, the transceiver of the wireless device is switched off without completing the reception of the entire beacon.

The present invention relates to a method and an apparatus which enable a terminal to transmit a signal for device-to-device (D2D) communication in a wireless communication system. Specifically, the present invention transmits a synchronization signal for D2D communication and a demodulation reference signal (DM-RS) for demodulation of the synchronization signal, wherein the base sequence of the demodulation reference signal is generated using a synchronization reference ID.
