Problems solved by technology

When D2D communication resources reuse cellular communication resources and adopt semi-centralized scheduling, the resources allocated by the base station for D2D UEs may also be scheduled for cellular communication data transmission, because the communication resources used by D2D communication and cellular communication are not allocated by the same If a base station performs scheduling, it is possible that cellular communication and D2D communication of the same UE are performed in the same subframe, resulting in in-band spurious or in-device self-interference problems
[0015] For example, in the scenario where D2D communication multiplexes cellular uplink resources, if the UE sends cellular uplink data and receives D2D communication data in the same subframe, the sending of cellular data will seriously interfere with the reception of D2D data and reduce resource usage efficiency; in addition, D2D UE In the case of only one transceiver, D2D communication and cellular communication cannot be transmitted and received at the same time. If the D2D UE’s cellular communication and D2D communication are scheduled at the same time, the D2D communication or cellular communication cannot be carried out smoothly.
[0016] To sum up, in the semi-centralized scheduling scenario, how to coordinate the resource scheduling of cellular communication and D2D communication, there is no solution in related technologies

Description

technical field [0001] The present invention relates to communication technology, in particular to a communication resource management method, equipment and system. Background technique [0002] With the development of wireless multimedia services, the demand for high data rate and user experience is increasing, which puts higher requirements on the system capacity and coverage of traditional cellular networks. On the other hand, social networking, short-distance data sharing, local advertising, etc. The popularity of applications has gradually increased people's demand for understanding and communicating with people or things of interest nearby and proximity services (PS, Proximity Services). Traditional cell-based cellular networks have limitations in high data rates and proximity services support. Against this background of demand, Device-to-Device (D2D, Device-to-Device) technology, which represents a new direction for the development of future communication technology, ...
