US 2019/0245589 A1 · ANTENNA PORT CONFIGURATION METHOD AND APPARATUS

Abstract

An antenna port configuration method and apparatus are provided. The method includes: obtaining, by an access network device, M reference signal received power RSRP differences, where the M RSRP differences indicate radio signal strengths of N radio remote units RRUs, and both M and N are positive integers greater than 1; determining, by the access network device based on the M RSRP differences, an order of traversing the N RRUs; and for any RRU of the N RRUs, configuring, by the access network device, same antenna ports for two RRUs in the traversal order that are adjacent to the RRU, and configuring different antenna ports for the RRU and the RRUs adjacent to the RRU.
