Abstract
A method of data transmission includes receiving, by a user equipment (UE) from a base station (BS), a configuration message including one or more signal quality indicators associated with configuration parameters of a first uplink beam and determining, by the UE, configuration parameters associated with a second uplink beam. The determining is based on: the one or more signal quality indicators associated with configuration parameters of the first uplink beam and the configuration parameters of the first uplink beam. The method further includes configuring, by the UE, the second uplink beam based on the determined configuration parameters for the second uplink beam and transmitting, by the UE to the BS, uplink data or control information using the second uplink beam.
Claims15
A method of data transmission, comprising the steps of:
- receiving, by a user equipment (UE) from a base station (BS), a configuration message including one or more signal quality indicators associated with configuration parameters of a first uplink beam;
- determining, by the UE, configuration parameters of a second uplink beam based on:
- the one or more signal quality indicators associated with the configuration parameters of the first uplink beam;
- and
- the configuration parameters of the first uplink beam;
- configuring, by the UE, the second uplink beam based on the determined configuration parameters of the second uplink beam;
- and
- transmitting, by the UE to the BS, uplink data or control information using the second uplink beam.
A method of data transmission, comprising:
- determining, by a base station (BS), configuration parameters of a first uplink beam;
- and
- transmitting, by the BS, to a user equipment (UE), a configuration message including one or more signal quality indicators associated with the configuration parameters of the first uplink beam,
- wherein configuration parameters of a second uplink beam are determined by the UE based on:
- the one or more signal quality indicators associated with the configuration parameters of the first uplink beam;
- and
- the configuration parameters of the first uplink beam, and
- wherein the method further comprises:
- receiving, from the UE, uplink data or control information transmitted using the second uplink beam.
A user equipment (UE), comprising:
- a transceiver configured to:
- receive a configuration message including one or more signal quality indicators associated with configuration parameters of a first uplink beam;
- and
- transmit uplink data or control information using a second uplink beam;
- and
- a processor in communication with transceiver, the processor being configured to:
- determine the configuration parameters of the second uplink beam based on:
- the one or more signal quality indicators associated with the configuration parameters of the first uplink beam;
- and
- the configuration parameters of the first uplink beam;
- and
- configure the second uplink beam based on the determined configuration parameters of the second uplink beam.
