Abstract
Aspects of the present disclosure provide techniques for informing devices of the use of transmit and receive beams in a beamforming communication system. An exemplary method includes determining a plurality of beam directions for a device to use in different transmission time intervals (TTIs) of a TTI burst, and sending a directional transmission to the device indicating at least one of the beam directions.
Claims30
A method for wireless communications by an apparatus, comprising:
- determining a plurality of beam directions for a device to use in different transmission time intervals (TTIs) of a TTI burst;
- and
- sending a directional transmission to the device indicating at least one of the beam directions.
A method for wireless communications by an apparatus, comprising:
- determining a plurality of beam directions for a device to use in different transmission time intervals (TTIs) of a TTI burst;
- determining, based at least on arrival of traffic for the device, whether to send the traffic to the device via a beam direction in the TTI burst;
- and
- sending a directional transmission to the device indicating at least one of the beam directions, if the determination whether to send the traffic was to send the traffic to the device via the beam direction.
A method for wireless communications by an apparatus, comprising:
- attempting to decode, in a control symbol, a directional transmission, from a device, indicating at least one beam direction for the apparatus to use in different transmission time intervals (TTIs) of a TTI burst;
- and
- determining, if the directional transmission is decoded, not to monitor one or more TTIs of the TTI burst based on information in the directional transmission.
An apparatus for wireless communications, comprising:
- a processing system configured to:
- determine a plurality of beam directions for a device to use in different transmission time intervals (TTIs) of a TTI burst;
- and
- send a directional transmission to the device indicating at least one of the beam directions;
- and
- a memory coupled with the processing system.
