Abstract
Embodiments of the present disclosure provide methods, apparatus and computer program products for transmitting and receiving an uplink signal on physical control channel. A method comprises: determining that a terminal device has a capability of transmitting the uplink signal on physical control channel in at least a first time instant and a second time instant coherently; performing a first transmission of the uplink signal on physical control channel in the first time instant in a first set of subcarriers; and performing a second transmission of the uplink signal on physical control channel in the second time instant in a second set of subcarriers.
Claims19
A method for transmitting an uplink signal on physical control channel, the method comprising:
- determining that a terminal device has a capability of transmitting the uplink signal on physical control channel in at least a first time instant and a second time instant coherently;
- performing a first transmission of the uplink signal on physical control channel in the first time instant in a first set of subcarriers;
- and
- performing a second transmission of the uplink signal on physical control channel in the second time instant in a second set of subcarriers;
- wherein the capability of transmitting the uplink signal on physical control channel in at least the first time instant and the second time instant coherently is determined based on at least one of the following:
- whether the first time instant and the second time instant are consecutive;
- a change in transmission power between the first time instant and the second time instant:
- a frequency offset between a central frequency of the first set of subcarriers and a central frequency of the second set of subcarriers;
- and
- an uplink spatial relation between uplink control channel transmissions in the first time instant and the second time instant.
A method for receiving an uplink signal on physical control channel, the method comprising:
- determining that a terminal device has a capability of transmitting the uplink signal on physical control channel in at least a first time instant and a second time instant coherently;
- receiving from the terminal device, a first transmission of the uplink signal on physical control channel in the first time instant in a first set of subcarriers;
- and
- receiving from the terminal device, a second transmission of the uplink signal on physical control channel in the second time instant in a second set of subcarriers;
- wherein the capability of transmitting the uplink signal on physical control channel in at least the first time instant and the second time instant coherently is determined based on at least one of the following:
- whether the first time instant and the second time instant are consecutive;
- a change in transmission power between the first time instant and the second time instant:
- a frequency offset between a central frequency of the first set of subcarriers and a central frequency of the second set of subcarriers;
- and
- an uplink spatial relation between uplink control channel transmissions in the first time instant and the second time instant.
An apparatus for transmitting an uplink signal on physical control channel, the apparatus comprising:
- one or more processors;
- and
- one or more memories comprising computer program codes,
- the one or more memories and the computer program codes configured to, with the one or more processors, cause the apparatus to:
- determine that a terminal device has a capability of transmitting the uplink signal on physical control channel in at least a first time instant and a second time instant coherently;
- perform a first transmission of the uplink signal on physical control channel in the first time instant in a first set of subcarriers;
- and
- perform a second transmission of the uplink signal on physical control channel in the second time instant in a second set of subcarriers;
- wherein the capability of transmitting the uplink signal on physical control channel in at least the first time instant and the second time instant coherently is determined based on at least one of the following:
- whether the first time instant and the second time instant are consecutive;
- a change in transmission power between the first time instant and the second time instant;
- a frequency offset between a central frequency of the first set of subcarriers and a central frequency of the second set of subcarriers;
- and
- an uplink spatial relation between uplink control channel transmissions in the first time instant and the second time instant.
