Abstract
The described technology is generally directed towards dynamically changing which quadrature amplitude modulation (QAM) table a user equipment is to use based on channel quality information. A network schedules a user equipment with 256 QAM modulation if the user equipment recommends 256 QAM in the CQI report (and the scheduler decides to use 256 QAM for that particular user equipment). The network indicates to the user equipment that it has to use 256 QAM modulation and coding scheme (MCS) table and not the configured QAM MCS table while determining the scheduling parameters by decoding PDCCH.
Claims20
A method, comprising:
- sending, by a user equipment comprising a processor, channel quality indicator data to network equipment;
- and
- receiving, by the user equipment from the network equipment via a second downlink control channel that is separate from a first downlink control channel that carries scheduling information to the user equipment, an indication that the user equipment is to use an updated modulation and coding scheme data structure having a higher order than a current order of a previously configured modulation and coding scheme data structure used by the user equipment, wherein the second downlink control channel does not carry any scheduling information to the user equipment.
A user equipment, comprising:
- a processor;
- and
- a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
- transmitting channel quality indicator data to network equipment;
- and
- receiving, from the network equipment via a second downlink control channel that is separate from a first downlink control channel that carries scheduling information to the user equipment, an indication that the user equipment is to use an updated modulation and coding scheme data structure having a higher order than a current order of a previously configured modulation and coding scheme data structure used by the user equipment, wherein the second downlink control channel does not carry any scheduling information to the user equipment.
A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:
- communicating channel quality indicator data to network equipment;
- and
- receiving, from the network equipment via a second downlink control channel that is separate from a first downlink control channel that carries scheduling information to the user equipment, an indication that the user equipment is to use an updated modulation and coding scheme data structure having a higher order than a current order of a previously configured modulation and coding scheme data structure used by the user equipment, wherein the second downlink control channel does not carry any scheduling information to the user equipment.
