Method and device for selecting uplink power

Abstract

The invention provides a method and a device for selecting uplink power and relates to the technical field of communication. The method comprises the following steps of obtaining an uplink power adjustment value of each cell in a to-be-adjusted network area; carrying out uplink power adjustment on the corresponding cell according to the uplink power adjustment value and recording uplink traffic of the to-be-adjusted network area after adjustment; and selecting the uplink power adjustment value of each cell as an uplink operating power adjustment value of each cell in the to-be-adjusted network area when the uplink traffic is greater than a first threshold. The scheme of the method solves the problems that MU-MIMO users of packet small-traffic services cannot effectively adjust the uplink power, the traffic gain cannot be effective and even the traffic gain is reduced due to the interference between the users.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for selecting uplink power. Background technique [0002] Uplink MU-MIMO (Multiple User-Multiple Input and Multiple Output, multi-user multiple-input multiple-output technology) is an important means to improve throughput of LTE (Long Term Evolution, long-term evolution) cells. At the base station, user selection and pairing and multi-user detection need to be completed. Different users can use the same time-frequency resources under the condition of wireless isolation to improve the spectrum reuse coefficient of the cell and improve the overall throughput. For example, figure 1 shown. [0003] Since the signals come from different users and pass through different channels, the degree of mutual interference between users is different. At present, the method used to reduce the interference of paired users mainly adopts the orthogonalization of...

However, in actual commercial networks, since users are all sudden small packets and small traffic services, such as WeChat, QQ, VOLTE services, etc., the duration is one or more scheduling opportunities or scheduling is performed every fixed interval (such as VOLTE, every 20 ms per scheduling packet), the service traffic ends within one or several radio frames, and within such a short period of time, the uplink MU-MIMO users have not had time to effectively adjust the service in place, so there are uplink MU-MIMO users The risk that the traffic gain of the network will not achieve the effect or even be reduced due to interference between users
