US 11,539,422 B2 · Beam management method, terminal, network device, and storage medium

Abstract

Embodiments of this application provide a beam management method, a terminal, a network device, and a storage medium. The method includes: when a quantity of reference signals whose RSSIs are greater than a first preset value in reference signals received on a first time-frequency resource on one of one or more beams is less than a second preset value, detecting, by the terminal, a reference signal and/or downlink indication information (used to indicate a sending status of the reference signal on the first time-frequency resource and/or a second time-frequency resource on the beam) from the network device on the second time-frequency resource on the beam. Further, when receiving the downlink indication information on the second time-frequency resource on the beam, the terminal continues to detect a reference signal from the network device on the beam, thereby saving communications system resources.

A beam management method, comprising:

detecting a reference signal from a network device on a first time-frequency resource on one or more beams;
detecting at least the reference signal or downlink indication information from the network device on a second time-frequency resource on a beam of the one or more beams in response to a quantity of reference signals, whose received signal strength indicators (RSSIs) are greater than a first preset value in reference signals received on the first time-frequency resource on the beam of the one or more beams, being less than a second preset value, wherein the downlink indication information indicates a sending status of the reference signal on the first time-frequency resource or the second time-frequency resource on the beam of the one or more beams;
and
continuing to detect the reference signal from the network device on the beam of the one or more beams in response to the downlink indication information being received on the second time-frequency resource on the beam of the one or more beams.

A beam management method, comprising:

performing, by a network device, idle channel listening on a second time-frequency resource on one or more beams;
and
sending, by the network device, a reference signal and downlink indication information to a terminal on the second time-frequency resource on a beam of the one or more beams in response to the second time-frequency resource on the beam of the one or more beams being idle, wherein the downlink indication information indicates a sending status of the reference signal on a first time-frequency resource or the second time-frequency resource on the beam of the one or more beams, and the first time-frequency resource is before the second time-frequency resource in a time domain.

A terminal, comprising a processor and a memory, wherein

the memory has a storage medium configured to store non-transitory instructions;
and a processor connected to the memory, the processor configured to execute the non-transitory instructions, causing the terminal to:
detect a reference signal from a network device on a first time-frequency resource on one or more beams;
detect at least the reference signal or downlink indication information from the network device on a second time-frequency resource on a beam of the one or more beams in response to a quantity of reference signals, whose received signal strength indicators (RSSIs) are greater than a first preset value in reference signals received on the first time-frequency resource on the beam of the one or more beams, being less than a second preset value, wherein the downlink indication information indicates a sending status of the reference signal on the first time-frequency resource or the second time-frequency resource on the beam of the one or more beams;
and
continuing to detect the reference signal from the network device on the beam of the one or more beams in response to the downlink indication information being received on the second time-frequency resource on the beam of the one or more beams.
