Abstract
In accordance with an embodiment, a method of operating a base station configured to communicate with at least one user device includes transmitting a reference signal to the at least one user device, receiving channel quality information from the at least one user device, and forming a beam based on the channel quality information received from the at least one user device.
Claims20
A user equipment (UE) configured to communicate wirelessly in a wireless network, the UE comprising:
- a processor;
- and
- a non-transitory computer readable storage medium storing programming for execution by the processor, the programming including instructions to:
- receive multiple reference signals transmitted over different beam directions from a base station (BS);
- transmit, to the BS, at least one index identifying at least one of the multiple reference signals received from the BS, the at least one index indicating at least one beam direction over which the at least one of the multiple reference signals are transmitted;
- and
- receive, from the BS, at least one data signal transmitted over at least one beam determined in accordance with the at least one index identifying the at least one of the reference signals.
A method of operating a user equipment (UE) configured to communicate wirelessly in a wireless network, the method comprising:
- receiving, by the UE, multiple reference signals transmitted over different beam directions from a base station (BS);
- transmitting, by the UE to the BS, at least one index identifying at least one of the multiple reference signals received from the BS, the at least one index indicating at least one beam direction over which the at least one of the multiple reference signals are transmitted;
- and
- receiving, by the UE from the BS, at least one data signal transmitted over at least one beam determined in accordance with the at least one index identifying the at least one of the reference signals.
A computer program product comprising computer executable instructions stored on a non-transitory computer-readable medium, wherein when executed by a processor, the instructions cause the processor to:
- receive multiple reference signals transmitted over different beam directions from a base station (BS);
- transmit, to the BS, at least one index uniquely identifying at least one of the multiple reference signals received from the BS, the at least one index indicating at least one beam direction over which the at least one of the multiple reference signals are transmitted;
- and
- receive, from the BS, at least one data signal transmitted over at least one beam determined in accordance with the at least one index identifying the at least one of the reference signals.
A non-transitory computer-readable medium configured to store a computer program comprising instructions, wherein when executed by a processor, the instructions cause the processor to:
- receive multiple reference signals transmitted over different beam directions from a base station (BS);
- transmit, to the BS, at least one index identifying at least one of the multiple reference signals received from the BS, the at least one index indicating at least one beam direction over which the at least one of the multiple reference signals are transmitted;
- and
- receive, from the BS, at least one data signal transmitted over at least one beam determined in accordance with the at least one index identifying the at least one of the reference signals.
