Abstract
The present disclosure relates to communications methods, systems, and devices. One example communications method includes when a base station determines that a quasi-co-location (QCL) relationship exists between antenna ports of at least two serving cells in a same serving cell group, sending, by the base station and to user equipment (UE), QCL indication signaling used to indicate that the QCL relationship exists between the antenna ports of the at least two serving cells in the same serving cell group, where the same serving cell group is a group predefined according to a preset rule or is a group obtained after the base station groups serving cells allocated to the UE.
Claims11
A communications method, comprising:
- receiving, by user equipment (UE), quasi-co-location (QCL) indication signaling from a base station, wherein the QCL indication signaling is used to indicate that a QCL relationship exists between antenna ports of at least two serving cells in a same serving cell group, and wherein the same serving cell group is a group obtained after the base station groups serving cells allocated to the UE or is a group predefined according to a preset rule;
- and
- determining, by the UE and based on the QCL indication signaling, to receive reference signals of the serving cells by using a same receive beam or transmit reference signals of the serving cells by using a same transmit beam in the at least two serving cells whose antenna ports are in the QCL relationship and that are in the same serving cell group.
A communications method, comprising:
- receiving, by user equipment (UE), quasi-co-location (QCL) indication signaling from a base station, wherein the QCL indication signaling is used to indicate that a QCL relationship exists between antenna ports of serving cells in different serving cell groups, and wherein the different serving cell groups are groups obtained after the base station groups serving cells allocated to the UE or are groups predefined according to a preset rule;
- and
- determining, by the UE based on the QCL indication signaling, to receive reference signals of the serving cells by using a same receive beam or transmit reference signals of the serving cells by using a same transmit beam in the serving cells whose antenna ports are in the QCL relationship and that are in the different serving cell groups.
A terminal, comprising a receiver and at least one processor, wherein the receiver is configured to:
- receive quasi-co-location (QCL) indication signaling from a base station, wherein the QCL indication signaling is used to indicate that a QCL relationship exists between antenna ports of at least two serving cells in a same serving cell group, and wherein the same serving cell group is a group obtained after the base station groups serving cells allocated to the terminal or is a group predefined according to a preset rule;
- and
- wherein the at least one processor is configured to determine, based on the QCL indication signaling, to receive reference signals of the serving cells by using a same receive beam or transmit reference signals of the serving cells by using a same transmit beam in the at least two serving cells whose antenna ports are in the QCL relationship and that are in the same serving cell group.
