In an embodiment, a multi-carrier signal (e.g., an OFDM signal) is received over a channel.

US08717980B2 Method for the early establishment of uplink TBFs
A mobile station operating in EGPRS mode needs to the early establishment of an uplink TBF although has not data to send, at the only precautionary purpose of preventing an intolerable latency negatively affecting the subsequent delay-sensitive transmissions. To this aim, the mobile sends a Packet Channel Request message in one phase access mode including a new establishment cause called “Early TBF establishment”. The network establishes an uplink TBF indicating the requester and assigns a radio resource on one PDCH channel or more. Then the network schedules the transmission from the mobile station also when it does not have data to transmit other than dummy packets. This is performed through the USF flags in the usual manner. As soon as actual data become available for transmission, the mobile send them instead of dummy packets. In an alternative embodiment the mobile sends the Packet Channel Request message in two phase access mode. As soon as the Packet Uplink Assignment message is received by the mobile station, it sends a Packet resource Request message including an extended Uplink TBF information. The network behaves as in the previous case.
US08717979B2 Multiplexing multiple unsolicited grant service (UGS) users onto a same radio resource
The technology in this application multiplexes transmission associated with multiple users onto the same unsolicited grant service (UGS) radio resource(s) in a packet-based, radio communications system. Normally, the radio resources in a packet-based communications system are dynamically scheduled in response to radio resource requests associated with specific user devices, and the scheduled communications are designed not to use the same radio resource at the same time. However, an unsolicited grant of radio resources for communication between multiple user devices and the packet-based communications system is also established. The communications between those multiple user devices and the packet-based communications system use at least some of the same radio resources associated with the unsolicited grant at the same time. Because of this at least partial radio resource overlap/collision, each of the multiple user's data to be transmitted via the UGS is associated with a user-specific radio resource pattern. A user's radio resource pattern permits a radio receiver to extract that user's data from the received UGS signal that include multiple user transmissions.
