User terminal and radio communication method
According to the present disclosure, a user terminal has a receiving section that receives a MAC (Medium Access Control) control element, which includes one or more fields that respectively correspond to one or more control resource sets, and a control section that controls receipt of a downlink control channel, which is mapped to a given resource unit in the control resource sets, based on transmission configuration indicator (TCI) states of the control resource sets, shown in the fields.
1. A terminal comprising:
a receiver that receives a Medium Access Control (MAC) control element,
wherein the MAC control element includes a first field that indicates Bandwidth Part (BWP) in which Transmission Configuration Indicator (TCI) state of control resource set is indicated by the MAC control element, and includes one or more second fields that indicates TCI states corresponding to each of one or more control resource sets associated with one or more BWPs which is indicated by the first field, and
a processor that determines, based on the first field and the one or more second fields, the TCI states corresponding to each of the one or more control resource sets associated with the one or more BWPs.
2. A radio communication method for a terminal, comprising:
receiving a Medium Access Control (MAC) control element,
wherein the MAC control element includes a first field that indicates Bandwidth Part (BWP) in which Transmission Configuration Indicator (TCI) state of control resource set is indicated by the MAC control element, and includes one or more second fields that indicates TCI states corresponding to each of one or more control resource sets associated with one or more BWPs which is indicated by the first field, and
determining, based on the first field and the one or more second fields, the TCI states corresponding to each of the one or more control resource sets associated with the one or more BWPs.
3. A base station comprising:
a processor that controls generation of a Medium Access Control (MAC) control element based on Transmission Configuration Indicator (TCI) states corresponding to each of one or more control resource sets associated with one or more Bandwidth Parts (BWPs),
a transmitter that transmits the MAC control element,
wherein the MAC control element includes a first field that indicates BWP in which TCI state of control resource set is indicated by the MAC control element, and includes one or more second fields that indicates the TCI states corresponding to each of the one or more control resource sets associated with the one or more BWPs which is indicated by the first field.
4. A system comprising a terminal and a base station, wherein:
the terminal comprises:
a receiver that receives a Medium Access Control (MAC) control element,
wherein the MAC control element includes a first field that indicates Bandwidth Part (BWP) in which Transmission Configuration Indicator (TCI) state of control resource set is indicated by the MAC control element, and includes one or more second fields that indicates TCI states corresponding to each of one or more control resource sets associated with one or more BWPs which is indicated by the first field, and
a processor that determines, based on the first field and the one or more second fields, the TCI states corresponding to each of the one or more control resource sets associated with the one or more BWPs, and
the base station comprises:
a transmitter that transmits the MAC control element.
