Abstract
A technique is provided for beamforming training, including: transmitting, by a network node, common control signaling via a plurality of beams periodically according to a predetermined beam sweeping pattern, and transmitting, via a set of one or more beams in each of one or more sequential time-domain resources, an aperiodic downlink sounding burst to at least one user device to allow the at least one user device to perform beamforming training.
Claims21
An apparatus comprising
- at least one processor and at least one memory including computer instructions, when executed by the at least one processor, cause the apparatus to:
- transmit common control signaling via a plurality of transmission beams periodically according to a predetermined beam sweeping pattern, wherein the common control signaling comprises control signaling transmitted to user devices within a cell to allow the user devices to detect cell specific beams of the cell;
- and
- transmit, via a transmission beam of the plurality of transmission beams in each of a plurality of sequential time-domain resources, the transmission beam being the same for the plurality of sequential time-domain resources, an aperiodic downlink sounding burst to a user device for reception via a set of receiving beams of the user device in order to enable the user device to perform beamforming training.

A method for beamforming training, comprising:
- receiving, by a user device from a network node, common control signaling from a plurality of transmission beams according to a predetermined beam sweeping pattern, wherein the common control signaling comprises control signaling transmitted to user devices within a cell to allow the user devices to detect cell specific beams of the cell;
- receiving, via one of a set of receiving beams in each of a plurality of sequential time-domain resources, an aperiodic downlink sounding burst from one of the plurality of transmission beams, the one of the plurality of transmission beams being the same for the plurality of sequential time-domain resources;
- and
- performing beamforming training of the set of receiving beams based on the aperiodic downlink sounding burst to select a downlink receive beam from the set of receiving beams for receiving signals from the network node.
