Abstract
A method comprises: determining, from an indication that an initial uplink beam between a user equipment and a network node is misaligned with respect to a downlink beam between the network node and the user equipment, at least one misalignment angle between the initial uplink beam and the downlink beam; and reconfiguring the uplink beam based on the misalignment angle to produce a reconfigured uplink beam.
Claims20
A method, comprising:
- determining, from an indication that an initial uplink beam between a user equipment and a network node is misaligned with respect to a downlink beam between said network node and said user equipment, at least one misalignment angle between said initial uplink beam and said downlink beam, wherein the indication comprises at least a reduction in gain received by the network node, and wherein the at least one misalignment angle is determined by mapping the reduction in gain to prestored information comprising a plurality of misalignment angles;
- and
- reconfiguring said uplink beam based on said misalignment angle to produce a reconfigured uplink beam.
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including computer program code for one or more programs,
- the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following:
- determine from an indication that an initial uplink beam between a user equipment and a network node is misaligned with respect to a downlink beam between said network node and said user equipment, at least one misalignment angle between said initial uplink beam and said downlink beam, wherein the indication comprises at least a reduction in gain received by the network node, and wherein the at least one misalignment angle is determined by mapping the reduction in gain to prestored information comprising a plurality of misalignment angles;
- and
- reconfigure said uplink beam based on said misalignment angle to produce a reconfigured uplink beam.
A user equipment, comprising at least one processor and at least one memory including computer instructions that, when executed by the at least one processor, cause the user equipment to perform:
- determine from an indication that an initial uplink beam between said user equipment and a network node is misaligned with respect to a downlink beam between said network node and said user equipment, at least one misalignment angle between said initial uplink beam and said downlink beam, wherein the indication comprises at least a reduction in gain received by the network node, and wherein the at least one misalignment angle is determined by mapping the reduction in gain to prestored information comprising a plurality of misalignment angles;
- and
- reconfigure said uplink beam based on said misalignment angle to produce a reconfigured uplink beam.
