Abstract:
A mobile terminal (20) comprises a wireless interface (21) for communication with a cellular communication network (10). A logic (27) is configured to control the wireless interface (21) to perform a mode switching signalling to cause activation of a protocol mode selected from a plurality of protocol modes for communicating over the wireless interface (21). The logic (27) is configured to selectively activate or deactivate at least one signal processing unit (24, 25) as a function of the selected protocol mode. The at least one signal processing unit (24, 25) is configured to process data received or transmitted via the wireless interface (21).
Abstract:
An antenna switching method includes tuning respective signals provided to first and second antennas in a portable electronic device to at least one frequency band. The method may also include connecting the first antenna to an uplink signal path that is for transmissions through the first and second antennas, and performing impedance matching for the first antenna. The method may further include comparing a real-time performance characteristic of the first antenna with a real-time performance characteristic of the second antenna. The method may additionally include, responsive to determining that the second antenna has a stronger real-time performance characteristic than the first antenna while the first antenna is connected to the uplink signal path, switching from the first antenna to the second antenna by connecting the second antenna to the uplink signal path and disconnecting the first antenna from the uplink signal path, and performing impedance matching for the second antenna.

Abstract:
A user equipment (2, 4, 6) receives mobility information representing a time-dependent location change of a mobile cell (11, 21) of a cellular communication network. A cell of a plurality of cells (11, 21, 31) of cellular communication network is selected for the user equipment (2, 4, 6) to camp on. Selecting the cell comprises processing the mobility information to determine whether the user equipment (2, 4, 6) is to camp on the mobile cell (11, 21).
Abstract:
Locally available location data is analyzed to identify a country or region of the world in which an electronic device (10) is most likely being used. From the identified country or region, the electronic device configures a band scan order for a prioritized full band scan of channels supported by the electronic device. As part of the configuration, the electronic device places the frequencies most likely to be used for radio access technology in the identified country or region at the beginning of the band scan order.
Abstract:
A node (100) of a cellular network selects a first modulation scheme setting for a first radio link to a first device (10′). The first modulation scheme setting is selected from a set of modulation scheme settings, each identified by at least one corresponding index. On the basis of a mapping of each of the indices to a corresponding set of transmission parameters, the node (100) identifies a first set of link parameters mapped to the index corresponding to the selected first modulation scheme setting. The node (100) then configures the first radio link according to the identified first set of link parameters. Further, the node (100) selects a second modulation scheme setting for a second radio link to a second device (10).

Abstract:
The invention is directed to reducing paging overhead in a network. An exemplary method comprises: determining whether a user equipment (UE) is substantially stationary, wherein the UE is located in a first network cell associated with a network; in response to determining the UE is substantially stationary, transmitting an indicator to the network; determining whether the UE moves from the first network cell to a second network cell; and in response to determining the UE moves from the first network cell to the second network cell, transmitting updated location information associated with the UE to the network.
Abstract:
A power control method performed by a mobile communication terminal comprises determining a received signal code power of common pilot channel signals received from a base station on a common pilot channel in at least one time interval. A block error rate determination is performed to determine a block error rate for transmissions received from the base station. A downlink outer loop power control is performed in dependence on the determined received signal code power of the common pilot channel signals until the block error rate determination fulfills a convergence criterion.
