Abstract
The present disclosure discloses a method for performing beam management by a terminal, and a terminal and a base station supporting same. According to one applicable embodiment of the present disclosure, a terminal can determine beam information from reference signals received through a plurality of transmission reception points (TRPs) included in a base station, and report the beam information to the base station. Then, on the basis of the reported beam information, the base station can control at least one beam that provides a service to the terminal.
Claims15
A method for performing beam management (BM) by a user equipment (UE) connected to a plurality of transmission reception points (TRPs) in a wireless communication system comprising:
- receiving configuration information related to beam management (BM) from a base station (BS);
- and
- reporting beam information determined from a received reference signal (RS) to the base station (BS) based on the configuration information,
- wherein,
- based on the configuration information including first report configuration information, the beam information includes (i) first beam information related to a first beam having the best beam quality, and (ii) second beam information related to at least one second beam having a second best beam quality less than the best beam quality of the first beam, and
- based on the configuration information including second report configuration information, the beam information includes (i) the first beam information, and (ii) third beam information related to a third beam that has the worst beam quality while having the same channel measurement resource (CMR) as those of the first beam,
- wherein each beam is related to one of the plurality of TRPs.
A user equipment (UE) configured to perform beam management (BM) by connecting to a plurality of transmission reception points (TRPs) in a wireless communication system, the user equipment (UE) comprising:
- at least one transmitter;
- at least one receiver;
- at least one processor;
- and
- at least one memory operatively connected to the at least one processor, and configured to store instructions such that the at least one processor performs specific operations by executing the instructions,
- wherein the specific operations include:
- receiving configuration information related to beam management (BM) from a base station (BS);
- and
- based on the configuration information, reporting beam information decided by a received reference signal (RS) to the base station (BS),
- wherein,
- based on the configuration information including first report configuration information, the beam information includes (i) first beam information related to a first beam having the best beam quality, and (ii) second beam information related to at least one second beam having a second best beam quality less than the best beam quality of the first beam, and
- based on the configuration information including second report configuration information, the beam information includes (i) the first beam information, and (ii) third beam information related to a third beam that has the worst beam quality while having the same channel measurement resource (CMR) as those of the first beam,
- wherein each beam is related to one of the plurality of TRPs.
A base station (BS) configured to perform beam management (BM) by connecting to a plurality of transmission reception points (TRPs) in a wireless communication system, the base station (BS) comprising:
- at least one transmitter;
- at least one receiver;
- at least one processor;
- and
- at least one memory operatively connected to the at least one processor, and configured to store instructions such that the at least one processor performs specific operations by executing the instructions,
- wherein the specific operations include:
- transmitting, to a user equipment (UE), configuration information related to beam management (BM) through at least one of a plurality of transmission reception points (TRPs) connected to the base station (BS);
- transmitting, to the user equipment (UE), a reference signal (RS) through the plurality of TRPs;
- and
- receiving, from the user equipment (UE), beam information that is determined depending on the configuration information and the reference signal (RS),
- wherein,
- based on the configuration information including first report configuration information, the beam information includes (i) first beam information related to a first beam having the best beam quality, and (ii) second beam information related to at least one second beam having a second best beam quality less than the best beam quality of the first beam, and
- based on the configuration information including second report configuration information, the beam information includes (i) the first beam information, and (ii) third beam information related to a third beam that has the worst beam quality while having the same channel measurement resource (CMR) as those of the first beam,
- wherein each beam is related to one of the plurality of TRPs.
