Encoding and decoding data for group common control channels
First Claim
1. A method, comprising:
- masking, by a base station device comprising a processor, an information block with a radio network identifier, resulting in a masked information block;
encoding, by the base station device, the masked information block resulting in a code symbol;
facilitating, by the base station device, transmitting the radio network identifier to a group of mobile devices using a radio resource control channel before a common control channel is established; and
facilitating, by the base station device, transmitting the code symbol to the group of mobile devices via the common control channel.

Abstract
An improved technique for encoding and decoding of data for group common control channels is provided herein. Generally, the embodiments disclosed herein involve masking the information bits of the group common PDCCH (or group common control channel information) with the common RNTI, without using parity bits, which reduces the power requirements of the transmitter and receiver. In a first embodiment, the information block and the common RNTI can each be encoded using separate encoders, and then the encoded information block can be masked with the encoded common RNTI, and the resulting code symbol can be transmitted to the group of mobile devices. In a second embodiment, an information block can be appended with bits to match a size of the common RNTI, and then be masked by the common RNTI.

10. A mobile device, comprising:
-
a processor; and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising; receiving, from a transmitter device, a radio network identifier using a radio resource control channel before a common control channel has been established; establishing, based on the radio network identifier, the common control channel with the transmitter device; and receiving a code symbol from the transmitter device via the common control channel, wherein the code symbol resulted from a masked information block with the radio network identifier. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A non-transitory machine-readable storage medium, comprising executable instructions that, when executed by a processor of a device, facilitate performance of operations, comprising:
-
masking common downlink control information, resulting in a masked information block, wherein the common downlink control information comprises a radio network identifier; encoding the masked information block, resulting in a code symbol; transmitting the radio network identifier to a group of mobile devices using a radio resource control channel before a common control channel is established; and transmitting the code symbol to the group of mobile devices using the common control channel. - View Dependent Claims (19, 20)
