    Abstract: PROBLEM TO BE SOLVED: To enable handover between TDMA and CDMA base stations without interrupting communications.SOLUTION: A mobile wireless telecommunications system includes base stations of a first type operating according to a first air interface, and base stations of a second type operating according to a second air interface. A communications link is established over the first air interface between a mobile station and the first base station. Data is received from the mobile station responsive to a signal received by the mobile station over the second air interface from the second base station, substantially without interrupting the communications link with the first base station. The mobile station is handed over from the first base station to the second base station responsive to the data received therefrom.

    Abstract: PROBLEM TO BE SOLVED: To provide a method of correctly soft combining each downlink signal transmitted by each cell involved in a soft handoff operation.SOLUTION: A mobile station 101 is informed of a downlink data frame time offset by transmitting the downlink data frame time offset via an active set update message transmitted from a cell (102 or 103) to the mobile station 101. Once the active set update message is received, the data frame time offset information is provided to a timing block which may determine a data frame boundary of each downlink signal. The timing block adjusts the PN sequence timing corresponding to the downlink signal associated with the data frame time offset such that corresponding data symbols in each data frame are correctly soft combined in a combiner.

    Abstract: Techniques for supporting operation with enhanced uplink in inactive state are described. A user equipment (UE) may send an access preamble for random access while in an inactive state and may receive a message containing resources allocated to the UE. The allocated resources may be selected by a Node B from a pool of resources pre-allocated to the Node B for the enhanced uplink. The UE may send information (e.g., scheduling information and/or its UE identity) to the Node B using the allocated resources. The UE may receive an acknowledgement addressed to the UE based on the UE identity. The UE may remain in the inactive state and continue to use the allocated resources until they are de-allocated. Alternatively, the UE may transition to an active state and either continue to use the allocated resources or receive an allocation of new resources for the active state.
