Abstract

The embodiments of the present invention provide a method and base station for obtaining combining gain to improve data demodulation performance. The method includes the following steps: a main baseband processing chip receives uplink data and data sent from at least one assistant baseband processing chip, wherein the data sent from the at least one assistant baseband processing chip is sent to the main baseband processing chip after the at least one assistant baseband processing chip performs maximum ratio combining to the uplink data received by the at least one assistant baseband processing chip, and the uplink data is simultaneously sent from a user device to the main baseband processing chip and to the assistant baseband processing chip; the main baseband processing chip performs maximum ratio combining to the data received by the main baseband processing chip. Compared to the selective combining during the soft handover, the method provided by the embodiments of the present invention can obtain better gain and improve data demodulation performance.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and a base station for obtaining combining gains. Background technique [0002] With the continuous evolution of mobile communications, Universal Mobile Telecommunications System (UMTS, Universal Mobile Telecommunications System) has become or will soon become a mainstream standard for mobile communications. At the same time, the continuous popularization of smart phones has also rapidly increased the demand for data communication. In the case of limited spectrum bandwidth, it is a common pursuit of the industry to continuously tap spectrum utilization efficiency. [0003] In UMTS, there are softer handover, softer handover, and hard handover. Due to the difficulty of data exchange between base stations and the limited capacity of a single chip, not all cells of the same frequency can implement softer handover. Generally, a softer handover is only selected between a f...
