Abstract

The embodiment of the present invention discloses a method for selecting and judging a remote radio frequency unit in the downlink direction, and the embodiment of the invention also discloses a device for selecting and judging a remote radio frequency unit in the downlink direction. Wherein, the method includes: the RRU selection decision period of the current RRU common cell arrives; according to the current downlink measurement amount of the user terminal and the uplink measurement amount of each RRU, it is determined that at least one RRU in the RRUs transmits the downlink carrier signal, or, According to the current downlink measurement amount of the user terminal, the uplink measurement amount of each RRU, and the power specification of each RRU, it is determined that at least one of the RRUs transmits a downlink carrier signal, and the downlink channel includes: a traffic channel and an independent dedicated control channel. By adopting the present invention, an appropriate RRU can be selected in good time to transmit a downlink carrier signal, and a reasonable conversion of the RRU transmission mode among single transmission, double transmission, and multiple transmission modes can be realized; the probability of RRU multi-transmission or double transmission can be reduced, thereby reducing network interference and RRU energy consumption.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and device for selecting and judging radio remote radio units in the downlink direction. Background technique [0002] Remote Radio Unit (RRU) shared cells are mainly used in high-speed rail networking scenarios. In this scenario, voice services are transmitted using the mode that all RRUs transmit downlink carrier signals or two RRUs transmit downlink carrier signals. [0003] With the continuous evolution of the existing network networking scenarios, the RRU shared cell is not only used in high-speed rail, but also more in the networking scenarios of ordinary residential areas. Regardless of the application scenario, maintaining multiple or two RRUs to transmit downlink carrier signals will inevitably increase base station energy consumption and network interference. Therefore, it is necessary to change the transmission mode of the RRU to reduce the probability t...
