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.
Claims29
A method of operating a base station configured to communicate wirelessly in a wireless network, the method comprising:
- transmitting one or more precoded reference signals to a user device;
- receiving at least one index from the user device, the at least one index associated with at least one precoded reference signal of the one or more precoded reference signals transmitted to the user device;
- and
- transmitting a beam-formed data signal to the user device, wherein transmitting the beam-formed data signal comprises adjusting a beam direction of the beam-formed data signal based on the at least one index received from the user device.
1 more element
A base station in a wireless network, the base station comprising:
- a processor;
- and
- a non-transitory computer readable storage medium storing programming for execution by the processor, the programming including instructions to:
- transmit one or more precoded reference signals to a user device;
- receive at least one index from the user device, the at least one index associated with at least one precoded reference signal of the one or more precoded reference signals transmitted to the user device;
- and
- transmit a beam-formed data signal to the user device, wherein the instructions to transmit the beam-formed data signal include instructions to adjust a beam direction of the beam-formed data signal based on the at least one index received from the user device.
