The present application discloses a method and a terminal device for wireless link monitoring. The method includes: starting, by a terminal device, a timer T310, when a number of out of sync (OOS) indications continuously received by the terminal device exceeds a first number N310; and determining, by the terminal device, whether to stop the timer T310 before the timer T310 expires, according to a number of in sync (IS) indications received after the timer T310 is started or according to a proportional relation between the IS indication and the OOS indication received after the timer T310 is started.

A user equipment (UE) device may determine its location with a high degree of precision, beyond the capability of other current methodologies. Specifically, a UE device may obtain High Precision (HIP) coordinates of its location based on Random Access Channel (RACH) messages that the UE device exchanges with multiple wireless stations. Using RACH messages to obtain HIP coordinates imposes little communication overhead or computational burden on the UE device and the network.

The invention relates to a wireless communication system (100) comprising a plurality of radio devices (102, 104). Each radio device of the plurality of radio devices (102, 104) is configured to: obtain timing information representing timing schedules of one or more other radio devices (102, 104) within its neighborhood; define, based on the obtained timing information, at least one timing schedule group (106, 108) into which the plurality of radio devices (102, 104) are divided and a size of each at least one timing schedule group (106, 108); and synchronize its own timing schedule with the timing schedule of the timing schedule group (106, 108) with the largest size. The invention relates also to a synchronization method (500) for the wireless communication system (100), a radio device (102, 104) for a wireless communication system, and a synchronization method for the radio device (102, 104).

A terminal determines a first frequency for accessing the network device Then, the terminal determines at least one second frequency based on the first frequency, where any second frequency is different from the first frequency, and at least two second frequencies are also different. The terminal selects at least two different second frequencies from the first frequency and the at least one second frequency. The terminal separately receives, in a time unit in a period by using the at least two different frequencies, an SSB from the network device. The terminal accesses the network device based on received one or more different SSBs.

A radio apparatus is configured to correlate signal data with stored synchronization data to generate synchronization correlation data. The signal data represents a received radio-frequency signal that encodes a data frame having a synchronization preamble comprising a plurality of instances of a predetermined synchronization sequence. The stored synchronization data represents the predetermined synchronization sequence. The synchronization correlation data is generated by correlating signal data representing the synchronization preamble with the stored synchronization data. While generating the synchronization correlation data, the radio apparatus identifies a first set of one or more peaks in the synchronization correlation data, and determines first synchronization information from the first set of one or more peaks. After generating more of the synchronization correlation data, the radio apparatus identifies a second set of one or more peaks in the synchronization correlation data, and determines second synchronization information from the second set of one or more peaks.

Techniques and apparatus for enabling and disabling of muting patterns in Radio Access Network (RAN) nodes for the purpose of allowing better detection and use of reference symbols used for over-the-air synchronization. An example method, in a base station operating in a wireless communications network, includes determining that a first neighbor cell of a plurality of neighbor cells is interfering with or is likely to interfere with a signal, from a second neighbor cell, that is used for synchronization. The method further includes sending, towards the first neighbor cell, a request for activation of a reference signal muting pattern by the first neighbor cell, the request including information identifying the second neighbor cell or a stratum of the second neighbor cell.

Aspects of the present disclosure provide techniques for interference measurements based on a priority value in a network (e.g., an Integrated Access and Backhaul (IAB) network). One example method generally includes determining, based on a priority level associated with each of a first wireless node, a second wireless node, or both, at least one configuration for communicating one or more synchronization signal blocks (SSBs) between the first wireless node and the second wireless node, each of the first wireless node and the second wireless node being configured to serve one or more child nodes, wherein the at least one configuration comprises information enabling the first wireless node or the second wireless node to manage interference to communications. In some aspects, the method may also include transmitting the at least one configuration to at least one of the first wireless node or the second wireless node.

In an aspect, a communications node (e.g., TRP or UE) obtains (e.g., measures) timing group delays associated with different positioning procedures to determine time drift information, and reports the time drift information to an external entity for position estimation. In some designs, positioning procedures may comprise round trip time (RTT) measurements or uplink or downlink Difference Of Arrival (TDOA) measurements. In some designs, the time drift information indicates a drift rate function.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a synchronization signal block (SSB) transmitted using a single carrier quadrature amplitude modulation (SC-QAM) waveform, wherein the SSB has a uniform bandwidth allocation for each of a primary synchronization signal (PSS) included in the SSB, a secondary synchronization signal (SSS) included in the SSB, and physical broadcast channel (PBCH) data included in the SSB. The UE may perform initial channel access based at least in part on the SSB. Numerous other aspects are described.
