Embodiment Construction
[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0022] figure 1 It is a flow chart of a method according to one aspect of the present invention, showing a process for allocating and scheduling bandwidth for user equipment located at the edge of a serving cell. Specifically, in step S1, base station 1 acquires the location information of base station 1 and the location information of the first user equipment; in step S2, base station 1 determines the location information of the first user equipment according to the location information of base station 1 and the first user equipment. The equipment is in the edge area of base station 1 and its adjacent area of adjacent base stations; in step S3, base station 1 is based on the first service bandwidth of the first user equipment in the edge area and the second user equipment in the adjacent area The second service bandwidth of the edge area and the frequen...

The object of the present invention is to provide a method and device for allocating and scheduling bandwidth for user equipment located at the edge of a serving cell. Wherein, the device obtains the location information of the base station and the location information of the first user equipment; and determines the serving cell of the first user equipment in the base station and its location in neighboring base stations based on the location information of the base station and the first user equipment. Neighboring cells; determine the first user equipment according to the first service bandwidth of the first user equipment in the serving cell, the second service bandwidth of the second user equipment in the neighboring cell, and the frequency bandwidth of the serving cell. The first scheduled bandwidth in the serving cell. Compared with the existing technology, the present invention enables the first user equipment at the edge of the serving cell to obtain the bandwidth of the serving cell to the maximum extent, realizes the dynamic allocation of the bandwidth of the first user equipment at the edge of the serving cell, and at the same time improves the efficiency of the serving cell. Throughput of user devices at the edge.
Description
technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a technique for allocating and scheduling bandwidth for user equipment located at the edge of a serving cell. Background technique [0002] In a wireless communication network, when a user equipment is at the edge of a serving cell, its communication quality suffers from co-channel interference from adjacent cells. [0003] In the prior art, in order to solve the above problems, when the user equipment is at the edge of the serving cell, the serving cell allocates a dedicated frequency band for the user equipment, and the dedicated frequency band accounts for about 1 / 3 of the frequency bandwidth of the serving cell. The 1 / 3 dedicated frequency band is different from the frequency band allocated to adjacent cells, so that co-channel interference will not occur. However, obviously, with this method, the spectral efficiency is very low, and even if there is n...
