Abstract

Provided is a beam indication method, which can save the scheduling overhead of downlink signal reception and uplink signal transmission. The method comprises: receiving first information from networkequipment, wherein the first information is used for determining a first receiving beam of a downlink signal and a first sending beam of an uplink signal; and determining a first receiving beam of the downlink signal and a first sending beam of the uplink signal according to the first information.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a method and device for indicating a beam. Background technique [0002] In a long term evolution (long term evolution, LTE) communication system, terminal equipment receives downlink signals and transmits uplink signals based on base station scheduling. Usually, the scheduling of the downlink signal and the scheduling of the uplink signal are independently scheduled based on respective physical downlink control channels (physical downlink control channel, PDCCH). That is to say, the network device schedules the reception of downlink signals through one PDCCH, and then schedules the transmission of uplink signals through another PDCCH. [0003] However, in some scenarios that require centralized control, the reception of downlink signals and the transmission of uplink signals generally occur in pairs. For example, the controller sends an instruction...
