Abstract: A method for processing an uplink reference signal includes determining a current baseband processing payload, and processing each of N received uplink reference signals according to a preset first condition in response to the baseband processing payload being less than a first preset value or processing each uplink reference signal in a signal set according to a preset second condition in response to the baseband processing payload being greater than a second preset value. The second preset value is greater than or equal to the first preset value. The signal set includes one or more of the N uplink reference signals. A baseband processing payload corresponding to processing an uplink reference signal according to the preset second condition is less than a baseband processing payload corresponding to processing an uplink reference signal according to the preset first condition. N is a positive integer.

Abstract: A channel correction method, used for performing channel correction on radio frequency apparatuses in a network area, is provided. The radio frequency apparatuses are divided into at least one radio frequency apparatus group. A correction resource location is set for each radio frequency apparatus in the radio frequency apparatus group. These resource locations may be stored in a form of configuration information in base stations where the radio frequency apparatuses are located, so that the base station controls each of these radio frequency apparatuses to send a correction signal in a respective correction resource location based on the configuration information, and to implement, by using these correction signals, channel correction for the radio frequency apparatuses in the radio frequency apparatus group. The method can implement joint channel correction for a plurality of radio frequency apparatuses and improve correction efficiency.

Abstract: An interference avoidance method, apparatus and a system are provided. A parameter related to a beam coverage direction is dynamically transferred, based on an interference detection result, between a baseband unit and a radio frequency unit to avoid interference in a space domain dimension. The radio frequency unit is supported to automatically adjust the beam coverage direction.

Abstract: This application discloses a data transmission method and a communication apparatus, to reduce a bandwidth requirement for data transmission through a fronthaul interface. A wireless device controller (or a wireless device) can separately encapsulate, into at least two packets, data carried by a plurality of types of physical channels in one time-domain unit, where data carried by at least one type of physical channel is encapsulated in each packet. Alternatively, the wireless device can encapsulate data corresponding to a plurality of physical antennas into at least two packets, where data corresponding to at least one physical antenna is encapsulated in each packet. Because a size of a packet transmitted between the wireless device controller and the wireless device is reduced, the bandwidth requirement for packet transmission through the fronthaul interface is reduced.
