Abstract: A method and an apparatus may be used for positioning a terminal device. Positioning measurement information for a terminal device is obtained by using a measurement apparatus on the terminal device side and/or an access node side, where the positioning measurement information is multipath positioning measurement information that is based on a single access node, and includes positioning measurement information of a main path and at least one reflection path that are based on the single access node, or positioning measurement information for at least two reflection paths. The measurement apparatus on the terminal device side and/or the access node side reports the positioning measurement information to a positioning function entity in a network, so that the positioning function entity can perform location estimation on the terminal device based on the positioning measurement information, to position the terminal device.

Abstract: In accordance to embodiments, methods, devices, and systems for determining initial transmissions in grant-free transmissions are disclosed. A UE receives a resource configuration for grant-free (GF) transmissions. The resource configuration comprises a periodicity parameter (P), a repetition number (K), and a sequence of redundancy version (RV) numbers corresponding to one or more RV types. The periodicity parameter defines a period having K transmission occasions (TOs), and each of the KTOs is associated with one RV number in the sequence of RV numbers. The UE performs an initial GF transmission of data in a TO of the K TOs in the period defined by the periodicity parameter. The TO is associated with an RV number corresponding to RV0.

Abstract: Embodiments provide a resource allocation method. The method includes: obtaining, by a first base station, an access transmission rate of at least one second base station, where the access transmission rate is a ratio of a total throughput to a total bandwidth occupied by all the user equipments. The throughput being of all user equipments for which the at least one second base station performs scheduling, The method further includes determining, by the first base station, resource allocation information of an access link and a backhaul link of the at least one second base station according to the access transmission rate and a backhaul transmission rate of the at least one second base station, and sending the resource allocation information. The backhaul transmission rate is a ratio of a total throughput of the backhaul link of the at least one second base station to a total bandwidth of the backhaul link.

Abstract: The present disclosure relates to the communications field, and provides a frame synchronization method, user equipment, and a base station, to implement frame time synchronization in a high-low frequency hybrid communications system. In one example method, a user equipment completes synchronization of a first frequency frame, determines a first moment of the synchronization of the first frequency frame, obtains a receive time difference, and completes synchronization of a second frequency frame according to the receive time difference and the first moment. The receive time difference is a time difference between a moment at which the user equipment receives the second frequency frame and a moment at which the user equipment receives the first frequency frame.

Abstract: Embodiments of the present invention disclose a user pairing method, a device and a system for realizing user scheduling. The method comprises: determining a first user of a time-frequency resource according to a preset resource allocation criterion; searching a preset pairing table according to a downlink channel state quantization code of the first user; and obtaining a paired downlink channel state quantization code which is paired with the downlink channel state quantization code of the first user, wherein the preset pairing table includes a pairing relationship among the downlink channel state quantization codes obtained by pre-calculating; identifying a paired user of the first user from users to be paired, wherein a downlink channel state quantization code of the paired user is the same as the paired downlink channel state quantization code. Through adopting of the present invention, complexity of real-time calculation of pairing during user scheduling can be lowered.

Abstract: A mobile communications terminal includes a metal backplane, a circuit board, and a metal frame. A feeding structure is located between a first ground point and a second ground point. A slot is located between the first ground point and the feeding structure. The first antenna uses, as a radiator, a part of the metal frame between the slot and the first ground point. The second antenna uses, as a radiation slot, a gap between the metal backplane and the part of the metal frame between the slot and the first ground point. The third antenna uses, as another radiation slot, a gap between the metal backplane and a part of the metal frame between the slot and the second ground point.
