SPREADTRUM SEMICONDUCTOR (NANJING) CO., LTD.

A beam scanning method and apparatus, and a computer-readable storage medium are provided. The beam scanning method includes: acquiring position information of a target UE; and determining a first optimal beam based on the position information of the target UE.

Provided are a method for window offset determination and a terminal, which are applied to a NTN communication system. The NTN communication system comprises a terminal and a network device. The method includes the following. The terminal acquires the first configuration information from the network device and determines a current window offset according to the first configuration information. The current window offset is used to represent an offset of a starting position of a downlink search space window corresponding to a current pre-configured uplink resource relative to a starting time, furthermore, the starting time is the end position of the current pre-configured uplink resource.

A method for resource identifier determination and related apparatuses are provided. The method includes the following. Receive higher-layer configuration information. Determine a first transmission resource of a first transmission point and a second transmission resource of a second transmission point at least according to the higher-layer configuration information. Receive downlink control information (DCI) according to the first transmission resource and the second transmission resource. Determine a physical uplink control channel (PUCCH) resource identifier at least according to the higher-layer configuration information and the DCI.

A data repetition transmission method and apparatus, a storage medium, a terminal and a base station are provided. The method includes: determining a number of repetition transmissions for data transmission based on repetition transmission number information statically or semi-statically configured by a network; and performing data transmission with the network using the determined number of repetition transmissions.

A resource allocation method and apparatus, and a storage medium, where the method includes: a terminal device obtains a resource configuration parameter of a resource pool, determines at least one PSCCH frequency-domain resource range on a frequency domain of the resource pool based on the resource configuration parameter, and performs SCI blind detection in the at least one PSCCH frequency-domain resource range, to determine an available transmission resource of a PRS in the resource pool based on an SCI blind detection result.

The present invention provides a roaming network selection method, a system, an electronic device and a storage medium, which are applicable to a terminal in a connected state at a roaming place. Said method includes receiving steering of roaming information containing a PLMN list and a timer issued by a network side device; determining whether a current service is an emergency service; starting the timer when the current service is a non-emergency service, and outputting notification information, so as to notify that network switching is to be performed after the timer expires; and performing network selection according to the PLMN list after the timer expires when no switching rejection instruction in response to the notification information is received. The present invention enables UE in a connected state at a roaming place to access a VPLMN with a higher priority, without affecting the running high-priority service.

A random access method and apparatus, and a computer-readable storage medium are provided. The random access method includes the following. when it is detected that a trigger condition is satisfied or a trigger indication is received, indication information is sent to a non-anchor network device; the indication information indicates that the non-anchor network device starts physical random access channel (PRACH) reception. A random access request message is sent to the non-anchor network device. By means of the solution, the static power consumption of the non-anchor network device can be effectively reduced.

The present disclosure provides a communication method. The method includes: sending a handover request to a second network device, where the handover request is used to request a handover of a terminal device to a relay device, and the relay device is within a coverage of the second network device; receiving a handover response from the second network device, where the handover response includes a first local identifier, the first local identifier is used to identify the terminal device in relay communication after a handover to the relay device, and the first local identifier is different from a device identifier of the terminal device.

A method and an apparatus for positioning-related reference signal transmission and reception, and a terminal are provided. The method for transmission includes the following. A positioning-related reference signal is transmitted in at least some of symbols between a first symbol and a second symbol in a target slot, where the first symbol is used for automatic gain control (AGC), and the second symbol is used for transmission/reception (Tx/Rx) switching.

An access method, a communication apparatus and a module device are provided. The method includes: receiving configuration information from a network device, wherein the configuration information indicates one or more first physical random access channel (PRACH) resources configured to indicate a physical uplink shared channel (PUSCH) repetition, and one or more second PRACH resources configured to indicate a non-PUSCH repetition; transmitting a random access request message to the network device through the first PRACH resource in the case of the PUSCH repetition; and transmitting the random access request message to the network device through the second PRACH resource in the case of the non-PUSCH repetition.
