Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a receive time difference (RTD) between a first base station and a second base station based at least in part on the UE using a common beam to receive transmissions from the first base station and the second base station. The UE may transmit information indicating the RTD between the first base station and the second base station, wherein the transmissions from the first base station and the second base station may be scheduled based at least in part on the RTD between the first base station and the second base station. Numerous other aspects are provided.
Claims30
A method of wireless communication performed by a user equipment (UE), comprising:
- determining a receive time difference (RTD) between a first base station and a second base station based at least in part on the UE using a common beam to receive transmissions from the first base station and the second base station, wherein the UE is configured to use the common beam to receive transmissions from the first base station using a first component carrier and receive transmissions from the second base station using a second component carrier different than the first component carrier;
- and
- transmitting information indicating the RTD between the first base station and the second base station, wherein the transmissions from the first base station and the second base station are scheduled based at least in part on the RTD between the first base station and the second base station.
A user equipment (UE) for wireless communication, comprising:
- a memory;
- and
- one or more processors coupled to the memory, the one or more processors configured to:
- determine a receive time difference (RTD) between a first base station and a second base station based at least in part on the UE using a common beam to receive transmissions from the first base station and the second base station, wherein the UE is configured to use the common beam to receive transmissions from the first base station using a first component carrier and receive transmissions from the second base station using a second component carrier different than the first component carrier;
- and
- transmit information indicating the RTD between the first base station and the second base station, wherein the transmissions from the first base station and the second base station are scheduled based at least in part on the RTD between the first base station and the second base station.
A non-transitory computer-readable medium storing one or more instructions for wireless communication, the one or more instructions comprising:
- one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the one or more processors to:
- determine a receive time difference (RTD) between a first base station and a second base station based at least in part on the UE using a common beam to receive transmissions from the first base station and the second base station, wherein the UE is configured to use the common beam to receive transmissions from the first base station using a first component carrier and receive transmissions from the second base station using a second component carrier different than the first component carrier;
- and
- transmit information indicating the RTD between the first base station and the second base station, wherein the transmissions from the first base station and the second base station are scheduled based at least in part on the RTD between the first base station and the second base station.
An apparatus for wireless communication, comprising:
- means for determining a receive time difference (RTD) between a first base station and a second base station based at least in part on the apparatus using a common beam to receive transmissions from the first base station and the second base station, wherein the apparatus is configured to use the common beam to receive transmissions from the first base station using a first component carrier and receive transmissions from the second base station using a second component carrier different than the first component carrier;
- and
- means for transmitting information indicating the RTD between the first base station and the second base station, wherein the transmissions from the first base station and the second base station are scheduled based at least in part on the RTD between the first base station and the second base station.
