Abstract

The invention provides a method, a device and a base station for allocation of a PRB resources, wherein the method comprises the following steps: acquiring a local community call PRB resource allocation start index according to PCI of a local community; determining a call PRB resource region of a user terminal according to the call PRB resource allocation start index; allocating call PRB resources for the user terminal in the call PRB resource region. In the embodiment provided by the invention, the community call PRB resource allocation start index is acquired according to the PCI of the community, and the call PRB resource region is determined for the user terminal according to the call PRB resource allocation start index to ensure that the call PRB resources of the communities with different PCIs are not overlapped; the call PRB resources are allocated to the user terminals in different call PRB resource regions, so that interference caused by a reason that the user terminals of the local community and the user terminals of an adjacent community use the PRB resources of the same PRB region is reduced or avoided, and thus the success rate for the base station to call the user terminals is increased.

Description

technical field [0001] The present invention relates to the technical field of communication networks, in particular to a PRB resource allocation method, device and base station. Background technique [0002] Paging in the Long Term Evolution (LTE) system is a downlink physical control channel scrambled by the terminal by monitoring whether there is a Paging-Radio Network Temporary Identifier (P-RNTI) in the paging subframe (Physical Downlink Control Channel, PDCCH), and further obtain the UEID information of the paging user terminal on the corresponding physical downlink shared channel (Physical Downlink Shared Channel, PDSCH), so as to determine whether there is a paging message for itself. [0003] Since the paging message is sent in a location tracking area (Tracking Area, TA), the paging data size of the cells belonging to the same TA area is the same. In addition, it is necessary to ensure that the user terminal in the edge area of ​​the cell can also receive the pagin...
