Abstract
The present disclosure provides a method for, in a wireless communication system comprising a UE and a base station including a plurality of cells, performing beam management by the UE via reporting a beam failure or partial beam failure related to one or more cells among a plurality of cells configured to the UE, and a UE and a base station which support the method. According to an embodiment applicable to the present disclosure, a UE can report a beam failure or partial beam failure on one or more cells to a base station, and the base station can quickly recognize the beam failure or partial beam failure on the one or more cells in response thereto.
Claims7
A method comprising:
- receiving configuration information configuring resources for transmitting a scheduling request (SR);
- detecting a partial beam failure (BF) in one or more cells among a plurality of cells based on qualities of a part of a plurality of reference signals configured for each of the one or more cells being lower than a threshold level;
- based on detection of the partial BF in the one or more cells, transmitting, to a base station (BS), an uplink signal including (i) identification information about the one or more cells and (ii) candidate beam information about at least one new beam for the one or more cells;
- and
- transmitting the SR for the detection of the partial BF based on the configuration information,
- wherein the resources are configured by the configuration information to be divided into a first resource for a detection of a BF and a second resource for the detection of the partial BF, and
- wherein the SR for the detection of the partial BF is transmitted in the second resource.

A user equipment (UE) comprising:
- at least one transmitter;
- at least one receiver;
- at least one processor;
- and
- at least one memory operatively coupled to the at least one processor and configured to store instructions causing, when executed, the at least one processor to perform operations comprising:
- receiving configuration information configuring resources for transmitting a scheduling request (SR);
- detecting a partial beam failure (BF) in one or more cells among a plurality of cells based on qualities of a part of a plurality of reference signals configured for each of the one or more cells being lower than a threshold level;
- based on detection of partial BF for the one or more cells, transmitting, to a base station (BS), an uplink signal including (i) identification information about the one or more cells and (ii) candidate beam information about at least one new beam for the one or more cells;
- and
- transmitting the SR for the detection of the partial BF based on the configuration information,
- wherein the resources are configured by the configuration information to be divided into a first resource for a detection of a BF and a second resource for the detection of the partial BF, and
- wherein the SR for the detection of the partial BF is transmitted in the second resource.
9 more elements
A base station (BS) comprising:
- at least one transmitter;
- at least one receiver;
- at least one processor;
- and
- at least one memory operatively coupled to the at least one processor and configured to store instructions causing, when executed, the at least one processor to perform operations comprising:
- transmitting, to a user equipment (UE), configuration information configuring resources for transmitting a scheduling request (SR);
- based on occurrence of partial beam failure (BF) for one or more cells among a plurality of cells configured for the UE, receiving, from the UE, an uplink signal including (i) identification information about the one or more cells and (ii) candidate beam information about at least one new beam for the one or more cells,
- wherein the partial BF is occurred based on qualities of a part of a plurality of reference signals configured for each of the one or more cells being lower than a threshold level;
- receiving the SR for the occurrence of the partial BF based on the configuration information;
- and
- recognizing the occurrence of the partial BF in the one or more cells based on the SR,
- wherein the resources are configured by the configuration information to be divided into a first resource for a detection of a BF and a second resource for the detection of the partial BF, and
- wherein the SR for the detection of the partial BF is transmitted in the second resource.
