摘要： A mobile communications system includes a radio access network, such as an Enhanced General Packet Radio Service (EGPRS) network, in which mobile stations are able to enter into a discontinuous transmission (DTX) mode. During DTX mode of a first mobile station that is allocated a channel portion (e.g., a time slot of a frame), the radio access network is able to multiplex traffic from another mobile station onto the same channel portion. A mechanism is provided to enable the first mobile station to send a request for re-allocation of the channel portion. The request includes a real-time fast access associated control channel (RTFACCH) resource request message (RTRRM). In response to the RTRRM, the radio access network sends an RTFACCH resource assignment message (RTUAM). An interleaving scheme is also provided for half-rate mobile stations, in which one set of traffic frames are interleaved over plural bursts according to a first algorithm and a second set of traffic frames are interleaved over plural bursts according to a second algorithm.

摘要： A wireless network includes wireless access systems for communicating with mobile stations. At least one of the wireless access systems is capable of communicating with multiple types of mobile stations. One type of mobile station communicates according to the Enhanced General Packet Radio Service (EGPRS) protocol, while another type of mobile station communicates according to the GSM/EDGE Radio Access Network (GERAN) protocol. The wireless access system includes control logic to select one of plural types of protocol stacks to use for communications over an air link with the different types of mobile stations. In response to an indicator of a first type, the wireless access system selects a first protocol stack, and in response to an indicator of a second type, the wireless access system selects a second protocol stack.

摘要： A communications system includes a wireless access network that is coupled to a packet-based data network. Packet-based calls may be established between a mobile station coupled to the wireless access network and a network endpoint coupled to the data network. For efficient call setup and call release, call control signaling, such as Session Initiation Protocol (SIP) messages and Resource Reservation Protocol (RSVP) messages, are carried in traffic channels over the wireless access network.

摘要： A method is provided for an access node to perform channel estimation. The method includes, when a UE and a relay node are present in a cell with the access node, the access node receiving from the UE and from the relay node DMRS that are cyclically shifted relative to one another. The method further includes the access node performing a first channel estimation based on the DMRS that was transmitted by the UE, performing a second channel estimation based on the DMRS that was transmitted by the at least one relay node, combining the first channel estimation with the second channel estimation to derive a combined channel estimation, using the first channel estimation to demodulate control information received from the UE, and using the combined channel estimation to demodulate data received from both the UE and the at least one relay node.
