Facilitating a two-stage downlink control channel in a wireless communication system
First Claim
1. An apparatus, comprising:
- a processor; and
a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising;
transmitting a first portion of a downlink control channel to a mobile device according to a first specification of parameters; and
transmitting a second portion of the downlink control channel to the mobile device according to a second specification of the parameters, wherein the second specification of the parameters is adaptively determined based on a channel condition in which the first portion of the downlink control channel is transmitted,wherein the first specification of the parameters is associated with a first type of modulation scheme and a first code rate, wherein the first type of modulation scheme and the first code rate are static irrespective of the channel condition in which the first portion of the downlink control channel is transmitted,wherein the second specification of the parameters is associated with a second type of modulation scheme, a second code rate and a search space, wherein the second type of modulation scheme, the second code rate and the search space are dynamically determined depending on the channel condition and the first specification of parameters.

Abstract
A two-stage downlink control channel is provided for a wireless communication system. In one example, an apparatus comprises a processor, and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations. The operation can comprise: transmitting a first portion of a downlink control channel to a mobile device according to a first specification of parameters; and transmitting a second portion of the downlink control channel to the mobile device according to a second specification of the parameters, wherein the second specification of the parameters is adaptively determined based on a condition of an environment in which the first portion of the downlink control channel is transmitted and wherein the second portion is dictated by the first specification of parameters.

14. A method, comprising:
-
determining, by a device comprising a processor, code rates and polynomial information for encoding of a downlink control channel; determining, by the device, modulation schemes, for modulation of the downlink control channel; and transmitting, by the device, at least a portion of information via the downlink control channel, wherein the information includes a first one of the code rates and a first one of the polynomial information, wherein the device is configured to update the code rates and polynomial information in response to an update condition being determined to be satisfied, wherein the first one of the code rates and the first one of the polynomial information are static irrespective of a channel condition in which at least the portion of the downlink control channel information is transmitted, and wherein a second code rate and a search space are determined as a function of the channel condition, the first one of the code rates, and the first one of the polynomial information. - View Dependent Claims (15, 16, 17, 18, 19, 20)
