Some embodiments of the present disclosure relate to processing an SSB, received in one radio frame, to obtain timing information helpful for allowing a UE to determine a boundary for the radio frame. Beneficially, changes in the periodicity of the transmission of SSB sets may allow the UE more frequent opportunities to determine a boundary for the radio frame. However, in the absence of additional information, the UE may not be able to determine a location, for an SSB set, within the radio frame. Aspects of the present application relate to a manner of including the additional information in an SSB and the processing of the SSB to obtain the additional information such that the UE may be assisted, by the additional information, in the task of determining a boundary for the radio frame.

Methods, systems, and devices for configurations for reference signaling in mobile communication technology are described. An example method for wireless communication includes transmitting, by a network node to a wireless device, a first signaling comprising information associated with a first reference signal, the information comprising at least one of a configuration of the first reference signal, an update information of the first reference signal, or a valid period of the first reference signal.

When a transmission timing of a downlink and a reception timing of an uplink at a radio communication node 100B are aligned, a radio communication node 100A determines an alignment value of the reception timing based on timing information used to determine transmission timing of the uplink, or an offset value from the timing information. The radio communication node 100A transmits the determined alignment value or offset value to the radio communication node 100B.

A terminal includes a reception unit that receives a synchronization signal block in an unlicensed band of a high frequency band higher than or equal to a frequency band of a frequency range 2 (FR2), the FR2 being in a range including a frequency range 1 (FR1) that is a low frequency band and the FR2 that is a high frequency band in a new radio (NR) system; and a control unit that identifies, based on the received synchronization signal block, an index of a candidate position for a transmission corresponding to the received synchronization signal block, from among candidate positions for transmitting a synchronization signal block, the number of the candidate positions being greater than a predetermined number.

Methods, systems, and devices for wireless communications are described. SSB based inter-frequency measurements may include configuring a UE to perform inter-frequency measurements without measurement gap within a measurement window, and applying scheduling restrictions to prioritize the inter-frequency measurements over uplink transmissions within the measurement window. The measurement window includes an SMTC window duration. Measurement resource sharing or restriction is described for SSB based inter-frequency measurement objects without measurement gap.

A radio receiver device determines whether a digital radio signal includes a predetermined cyclic preamble. An input portion samples the digital radio signal and generates a plurality of samples for storage in a buffer. A first autocorrelator correlates first and second subsets of the samples to generate a first correlation metric, the second subset having been stored in the buffer earlier than said first subset by an even integer multiple of half of the preamble period. A second autocorrelator correlates first and third subsets of the plurality of samples to generate a second correlation metric, the third subset having been stored in the buffer earlier than said first subset by an odd integer multiple of half of the preamble period. A processing portion calculates a difference between the correlation metrics and determines that the radio signal includes the predetermined cyclic preamble when the difference is greater than a threshold value.

The technology of this application relates to the field of communication technologies, and discloses a time synchronization method and an apparatus. The method includes a CU determines reference time of a terminal device at a reference point, and sends first information to the terminal device, where the first information is used to indicate the reference time of the terminal device at the reference point. After receiving the first information, the terminal device may perform time synchronization based on the reference time of the terminal device at the reference point. In this manner, the terminal device may obtain the reference time of the terminal device at the reference point from the CU, so that processing complexity of the terminal device can be effectively reduced, and power consumption of the terminal device can be reduced.

Aspects of the disclosure provide a method and apparatus for transmitting a synchronization broadcast transmission. At least one candidate transmission location corresponding to at least one synchronization signal/physical broadcast channel block (SSB) to be transmitted, is determined, where a number of the at least one candidate transmission location is greater than a number of SSBs in one time interval. Further, synchronization broadcast transmission including the at least one SSB is generated, and the generated synchronization broadcast transmission is transmitted at the at least one candidate transmission location in a beam sweeping manner.

The present application relates to a paging mechanism. In an example, a network can transmit SSBs periodically on multiple SSB beams. A UE can receive, during a DRX cycle, an SSB per detected SSB beam and perform SSB-based measurements. Based on these measurements, the UE can perform PDCCH monitoring and PDSCH decoding on at least two beams. The PDCCH monitoring can indicate a scheduled paging message from the network. The PDSCH decoding can allow the UE to determine the paging message.
