Link adaptation on downlink control channel in a wireless communications system
First Claim
1. A method, comprising:
- sending, by a network device of a wireless network and comprising a processor, first data indicating a first downlink control channel to a mobile device, wherein the first data indicating the first downlink control channel comprises a first control resource set indication that comprises a first parameter comprising a first modulation format to be used by the mobile device to decode the first downlink control channel at the mobile device and comprising a first frozen bit location for a first polar code of the first downlink control channel; and
determining, by the network device, a second control resource set indication for the mobile device, wherein the second control resource set indication comprises a second parameter comprising a second modulation format that is adaptively determined, by the network device, based on a condition of an environment determined to be associated with the mobile device and comprising a second frozen bit location for a second polar code of the second downlink control channel.

Abstract
Link adaptation on downlink control channels is provided herein. A method can comprise sending, by a network device of a wireless network and comprising a processor, first data indicating a first downlink control channel to a mobile device. The first data indicating the downlink control channel can comprise a first coreset indication that comprises a first parameter used to decode the first downlink control channel at the mobile device. The method can also include determining, by the network device, a second coreset indication for the mobile device. The second coreset indication can comprise a second parameter that can be adaptively determined based on a condition of an environment determined to be associated with the mobile device.

10. A system, comprising:
-
a processor; and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising; sending, to a mobile device, first data indicating a first downlink control channel that comprises a first indication of a first control resource set, wherein the first control resource set comprises a first parameter comprising a first modulation format that is determined a priori and usable to decode the first downlink control channel at the mobile device; determining a second control resource set for the mobile device, wherein the second control resource set comprises a second parameter comprising a second modulation format that is determined based on a condition of an environment of the mobile device; and sending, to the mobile device, second data indicating a second downlink control channel that comprises a second indication of the second control resource set, wherein the second control resource set comprises the second parameter usable to decode the second downlink control channel at the mobile device, wherein the first parameter comprises a first frozen bit location for a first polar code of the first downlink control channel, and wherein the second parameter comprises a second frozen bit location for a second polar code of the second downlink control channel. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A machine-readable storage medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:
-
sending first data indicating a first downlink control channel to a mobile device via a network device of network devices of a wireless network, wherein the first downlink control channel comprises a group common control channel, and wherein the first data indicating the first downlink control channel comprises a first control resource set indication that comprises a first parameter comprising a first modulation format for a decoding of the first downlink control channel at the mobile device; and determining a second control resource set indication for the mobile device, wherein the second control resource set indication comprises a second parameter comprising a second modulation format that is adaptively determined based on a condition of an environment determined to be associated with the mobile device, wherein the first parameter comprises a first frozen bit location for a first polar code of the first downlink control channel, and wherein the second parameter comprises a second frozen bit location for a second polar code of the second downlink control channel. - View Dependent Claims (18, 19)
