摘要： A resource reuse apparatus, user equipment, and a resource reuse method are disclosed. The method includes: monitoring, by first user equipment, idle resources so as to obtain a first idle resource set; claiming, in a first cycle, to use a first resource, where the first resource is a resource in the first idle resource set; determining whether the first resource exists in a first claimed resource set, where the first claimed resource set is a set of resources that are claimed to be used by another user equipment except the first user equipment; and if the first resource exists in the first claimed resource set, claiming, in a second cycle, to use a second resource, where the second resource is a resource, in the first idle resource set, that is different from the first resource; or reclaiming a resource after at least one cycle following the first cycle.

摘要： The present invention provides a signal measurement method and apparatus, where the method includes: receiving, by user equipment UE, a measurement configuration message sent by a base station, where the measurement configuration message is used to indicate a reference signal type; performing, by the UE according to the reference signal type indicated by the measurement configuration message, signal quality measurement on a cell to obtain a measurement result; and sending, by the UE, the measurement result to the base station. The method provided in embodiments of the present invention is used to resolve a technical problem in the prior art that normal communication of UE cannot be ensured because RSRP and/or RSRQ of neighboring cells cannot be measured based on an existing reference signal when the neighboring cells use different carrier types.

摘要： Example information transmission methods, terminal devices, and access network devices are described. One example information transmission method includes determining resources for carrying N pieces of uplink control information (UCI) partly overlap or completely overlap in time domain. The N pieces of UCI include at least one piece of beam channel quality information and at least one of a piece of channel state information or an acknowledgement (ACK)/a negative acknowledgement (NACK). A priority of the beam channel quality information is higher than a priority of the channel state information, and/or lower than a priority of the ACK/NACK.

摘要： Embodiments of the present disclosure provide a resource scheduling method, apparatus, and system. The embodiments of the present disclosure relate to the field of communications technologies and are used to resolve a problem of resource scheduling in Device-to-Device (D2D) communication. The method includes: sending, by a first node, first control signaling to a second node, where the first control signaling includes information about a resource for second control signaling transmission and information about a resource for data transmission; and receiving, by the second node, the first control signaling sent by the first node, and sending second control signaling to a third node by using the resource for the second control signaling transmission, and sending data to the third node by using the resource for the data transmission. The resource scheduling method, apparatus, and system can be applied to a data transmission device requiring relatively high delay performance.

摘要： Embodiments provide an information processing method, a base station, and user equipment. The method includes determining multiple subband groups, where the multiple subband groups are obtained by dividing multiple physical resource blocks corresponding to resource elements (REs) originally occupied by a CSI-RS, and each subband group in the multiple subband groups includes at least one subband. The method also includes determining a reference signal corresponding to each subband group in the multiple subband groups, where the reference signal corresponding to each subband group is generated by performing a precoding operation on the CSI-RS originally carried in first bearer REs in each subband in each subband group. Additionally, the method includes transmitting, using the first bearer REs in each subband group in the multiple subband groups, the reference signal corresponding to each subband group.
