ABSTRACT:
To transmit signaling, a base station obtains signaling for a group of channels used for data transmission and selected from a set of channels having constraints on usage. The base station compresses the signaling based on the channel constraints and obtains at least one message. If multiple messages are to be sent, then the assigned channels are partitioned into multiple subgroups, and the signaling for the channels in each subgroup is compressed to obtain a message for that subgroup. Each message is encoded at a spectral efficiency and transmitted at a power level selected for the message. A Cyclic Redundancy Check (CRC) value is appended to the message(s) for error detection. To receive the signaling, a terminal checks a received message with the appended CRC, decodes the message if the CRC passes, decompresses the decoded message based on the channel constraints, and extracts the signaling for an assigned channel.
