Abstract: A method is provided for operating a multi-bandwidth OFDMA system that can achieve an enhanced bandwidth efficiency due to windowing without significantly impacting the underlying physical design of the receive filters. The method comprises establishing a bandwidth over which the radio resources transmit signals, the bandwidth being comprised of an edge-band and a center-band. Narrow band radio resources are assigned to a portion of the bandwidth that is at least partially within the edge-band.

Abstract: 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.

Abstract: The present invention relates to a method for a handover of a UE (User Equipment) currently engaged in a voice call. More particularly, the invention relates to a handover from 1) a packet based radio where Voice Service is provided via VoIP over the radio and is controlled via Session Initiation Protocol (SIP) based signalling (e.g. LTE, E-UTRAN or WIMAX radio) to 2) a radio access network where Voice Service can be only provided via circuit switched (CS) domain (a visited mobile switching centre (VMSC) is needed) such as legacy 3GPP UMTS Terrestrial Radio Access Network (UTRAN)/ GSM/Edge Radio Access Network (GERAN) coverage. A MSC-S entity acting as a Packet Core Control Node on a Packet Switched (PS) network and as an Anchor Visited Mobile Switching Centre (VMSC) for a handover to a Circuit Switched (CS) network on the CS domain side is proposed, the MSC-S preparing a new path with a remote UE-B and a CS domain handover towards a target legacy radio coverage before requesting a UE- A to execute the handover.
