    摘要： In a wireless telecommunications network, a Code Division Multiple Access scheme is applied to data to encode it. The CDMA encoded data may be time multiplexed with other data symbols. The time multiplexed data are then applied to Single Carrier-Frequency Division Multiple Access, SC-FDMA, transmissions. The CDMA scheme may be used for relatively small payloads, such as those associated with voice traffic and control signals, and the other data symbols are used for higher date rate transmissions. This enables autonomous transmission, without scheduling, for smaller payloads. A transmitter includes a selector (3) for performing time multiplexing in the uplink, the required transmission scheme being indicated by the Hybrid Automatic Repeat Request,HARQ, ID. A first branch (1) carries the other data symbols and a second branch (2) carries data to be transmitted as a CDMA scheme. A CAZAC code may be used in encoding the CDMA data.

    摘要： A communication system includes a decentralized, flat architecture where a plurality of base nodes each include controller capabilities so that a centralized base node such as a radio network controller is not required. At least one of the base nodes acts as an anchor node. The anchor node associates a time stamp with at least one packet and provides that to the plurality of base nodes. In one example, a multicast approach is used by a router device for distributing the packet and the associated time stamp to the plurality of base nodes. Each base node controls a timing of a transmission of the at least one packet over a wireless interface responsive to the associated time stamp.

    摘要： A method is provided of transferring a call connection with a mobile terminal from a first network to a second network. The first network is capable of handling both circuit-switched and packet-switched modes of connection. The second network is capable of handling one of the packet-switched or circuit-switched modes of connection but not both. The terminal is capable of both packet-switched and circuit- switched call modes of connection. The method comprises the first network: identifying the location of the mobile terminal with respect to at least one of the networks, identifying the mobile terminal as being in a mode of connection not usable in the second network, instructing the mobile terminal to transfer the call connection to the other mode of connection, and transferring the call connection to the second network.

    摘要： The present invention provides a method involving a configurable random access channel structure. One embodiment of the method includes generating, at user equipment in a cell, a random access channel burst comprising a cyclic prefix, a preamble, and a number of repetitions of the preamble, wherein the cyclic prefix has a predetermined duration that is independent of the number of repetitions of the preamble, and wherein any user equipment in the cell generating random access channel bursts uses the number of repetitions of the preamble. This embodiment of the method also includes transmitting the random access channel burst over an air interface.

    摘要： A multicast status availability indication from an anchor (24) is provided to a plurality of base nodes (22) that are part of a multicast group serviced by the anchor (24). The availability status indication in one example is sent autonomously by the anchor (24) independent of any inquiry or attempted setup of a new session with that anchor by a base mode (22). The base modes (22) maintain a candidate anchor set that includes information regarding currently available anchors for establishing new sessions, for example.
