A method in a user equipment for updating a timing of a first cell is provided. The timing is the arrival time of a signal sent from a base station in the first cell relative to a clock in the user equipment in a wireless communication network. The user equipment measures a timing offset for the first cell and respective one or more second cells. When a quality of the timing offset measurement of the first cell is below a first threshold, the user equipment computes a timing offset estimate for the first cell based on the measured timing offset for the respective one or more second cells. The user equipment then updates the timing of the first cell based on the computed timing offset estimate.

Generic devices, systems and methods for multiple radio access technologies (RATs) are described. Arrangements can include, for example, a processor configured to execute procedures associated with different radio access technologies (RATs), a radio planner function configured to receive requests for radio resources from the procedures and further configured to selectively grant or deny radio access by the procedures in response to the requests, and a memory device configured to operate as a distributed data base to store data produced by at least one of the procedures and to provide the data to at least one other of the procedures.

Methods and systems for a generic multi-radio access technology

Generic devices, systems and methods for multiple radio access technologies (RATs) are described. An arrangement can include, for example, a multiple radio access technology (RAT) platform configured to enable communications with a plurality of different RATs using procedures associated with transceiver processing functions, wherein the procedures implement the transceiver processing functions through functional units (FUs) which perform operations, the FUs being implemented in at least one of hardware and software; and wherein the FUs are configured by functional unit descriptors (FUDs) which instruct an FU regarding at least one of: (a) from which memory location to fetch data to operate upon or parameters associated with an operation to be performed by the FU, (b) to which memory location to store data as a result of an operation and (c) a message type to output after the operation.

Generic devices, systems and methods for multiple radio access technologies (RATs) are described. A platform for allocating radio resources among a plurality of radio access technology (RAT) modules can include, for example, radio hardware configured to transmit and receive radio signals over an air interface using the plurality of RATs; and a radio planner connected to the radio hardware and configured to receive radio time reservation requests, each of which requests includes a priority value for the radio time reservation request, and to determine whether to grant or deny each of the radio time reservation requests based at least in part on the priority values.

A user equipment (UE) cell search involves tuning a demodulation frequency of the UE based on signals received from a first encountered cell and using a non-initial cell search procedure to continue searching for a cell that is qualified for camping on, wherein the non-initial cell search procedure relies on the demodulation frequency being within limits of accuracy that enable successful reception and decoding of received information. Prior to finding a qualified cell, information enabling a first discovered unqualified cell to again be found is saved. After a period of time during which the non-initial cell search procedure has been performed and before the UE's demodulation frequency is beyond acceptable limits of accuracy, the saved information is used to again tune the demodulation frequency based on reading signals from the first discovered unqualified cell. The UE then continues to perform the non-initial cell search procedure.
