Abstract

The invention provides a resource allocation method and a base station in an LTE uplink multi-user virtual MIMO system. The method includes: judging whether the current usage rate of the uplink physical resource blocks of the cell accessing the new user equipment is within a preset range; The first uplink rate obtained after the remaining physical resource blocks of the cell; according to the TBS index of each user equipment that has scheduled physical resource blocks in the cell after using the same physical resource block and the number of remaining physical resource blocks of the cell, the UE is estimated Each uplink rate after using the same physical resource block with each user equipment; select the user paired with the UE according to each uplink rate and the physical resource block occupancy rate of each user equipment when the UE uses the same physical resource block with each user equipment The device; according to the comparison result of the uplink rate corresponding to the user equipment and the first uplink rate, assigning a physical resource block to the UE for data transmission.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a resource allocation method and a base station in an LTE uplink multi-user virtual MIMO system. Background technique [0002] The existing multi-user virtual MIMO (Multiple-Input Multiple-Output) technology refers to that the base station uses multiple receiving antennas to perform weighted and combined operations on the signals on each receiving antenna with different weights to obtain different user The multi-user detection is performed on the user equipment multiplexed with the same time-frequency resource by multiple estimated values ​​of the signal of the equipment, and the effect that multiple user equipment transmits data on the same time-frequency resource is realized. Multi-user virtual MIMO not only obtains diversity gain and array gain like uplink receive diversity, but also obtains multiplexing gain brought by multi-user equipment using the sam...
