Abstract

Embodiments of the present invention provide a method and an integrated control point device for uplink power control. The method includes: acquiring uplink load information of a plurality of cells; identifying a first type of cell and a second type of cell in the plurality of cells; The relationship determines at least one cell cluster, wherein any cell cluster in the at least one cell cluster includes at least one cell of the first type and a cell of the first type or a cell of the second type adjacent to the at least one cell of the first type; Each cell cluster of the at least one cell cluster is jointly optimized for uplink power control parameters. The method and device for uplink power control in the embodiments of the present invention distinguish overloaded cells according to the uplink load information of multiple cells and divide the overloaded cells and their adjacent light-loaded cells into cell clusters for joint optimization of uplink power control parameters , so that the uplink interference in the cell cluster can be effectively coordinated.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and more specifically, to a method and device for uplink power control. Background technique [0002] In the LTE standard, the basic operating point control parameters of the uplink power include the uplink power reference value PO_PUSCH (P0) and the path loss compensation factor α. Since the basic operating point does not depend on the user's dynamic measurement feedback, it is also called an open-loop control parameter. The dynamic offset control parameters include control factors related to the transmission format and direct control parameters, and their specific values ​​depend on the dynamic measurement feedback of a single user, so they are also called closed-loop control parameters. The basic operating point control parameter PO_PUSCH is further divided into cell-level parameters P cell_specific and the user-level parameter P UE_specific , the cell-level parameter is a...
