Abstract
A communication device of reporting channel information comprises a storage unit for storing instructions and a processing means coupled to the storage unit. The processing means is configured to execute the instructions stored in the storage unit. The instructions comprise receiving a plurality of beamformed reference signals transmitted by a network via a plurality of beams, respectively; obtaining a plurality of channel quality indicators (CQIs) of the plurality of beams according to the plurality of beamformed reference signals; and transmitting a bitmap indicating whether the plurality of CQIs are greater than a threshold to the network.
Claims8
A communication device of reporting channel information, comprising:
- a storage unit, for storing instructions of:
- receiving a plurality of beamformed reference signals transmitted by a network via a plurality of beams, respectively;
- obtaining a plurality of channel quality indicators (CQIs) of the plurality of beams according to the plurality of beamformed reference signals;
- selecting a beam from the plurality of beams according to the plurality of CQIs;
- transmitting a beam index of the beam to the network;
- transmitting a channel state information (CSI) of the beam to the network;
- and
- transmitting information of at least one neighboring beam of the beam to the network;
- wherein the information of the at least one neighboring beam comprises at least one difference between a CQI of the beam and at least one CQI of the at least one neighboring beam;
- and
- a processing means, coupled to the storage unit, configured to execute the instructions stored in the storage unit.
A communication device of reporting channel information, comprising:
- a storage unit, for storing instructions of:
- receiving a plurality of beamformed reference signals transmitted by a network via a plurality of beams, respectively, wherein the plurality of beams belong to a plurality of beam groups;
- obtaining a plurality of channel quality indicators (CQIs) of the plurality of beams according to the plurality of beamformed reference signals;
- selecting a beam group from the plurality of beam groups according to the plurality of CQIs;
- transmitting a group index of the beam group to the network;
- determining an aggregated CSI according to that a joint data transmission is performed via at least one beam of the beam group;
- and
- transmitting the aggregated CSI to the network;
- and
- a processing means, coupled to the storage unit, configured to execute the instructions stored in the storage unit.
