Abstract: The invention relates to a technique for controlling a synchronization of a terminal device (10) with a wireless network, e.g. an LTE network, wherein data are transmitted as a continuous data signal on a radio interface (11, 12) while being processed block-wise in the terminal (10). A method embodiment of the technique for achieving at least a downlink (11) synchronization comprises establishing a time-address mapping (TAM, 36) indicative of an association of a reference time value of an internal clock (32) with a reference address in the reception data buffer (16); determining an address of data samples representing the received data block in the reception data buffer (16) based on the time-address mapping; and initiating a block-wise reading of the data block from the reception data buffer (16) based on the determined address.

Abstract: Congestion in a radio access network (RAN) associated with transporting uplink information originating from one or more mobile terminals is detected. That detected RAN congestion is reduced using any suitable technique (several examples are described) and may be implemented in one or more nodes in the RAN. One advantageous (but non-limiting) application is to a RAN that supports high speed uplink packet access (HSUPA) and/or one or more enhanced uplink dedicated channels (E-DCHs).

Abstract: A unified messaging system which can provide messaging services for a plurality of different “message types” is disclosed. The unified messaging system can serve as a single interface to a number of messaging services provided by various messaging components which use different message types (e.g., mail server). A unified message type is implemented and presented to a user as an abstract message. In addition, the unified messaging system can automatically determine, based on a first selected feature, if one or more message types should be used. A particular message type can also be automatically selected as a “best message type” based on one or more selected options.

Abstract: The present invention relates to a method and arrangement to enhance the communication performance in wireless communication systems. The method of the invention provides better adjustment of reported SINR in MIMO, and PARC-MIMO based communication systems. According to the method information relating to signal-to-interference-plus-noise ratio is determined by the user equipment and reported to the base station. The base station adjust reported SINRs using a model of the SINR dependences of power and code allocation. The dependences is modeled by a function comprising a first parameter relating only to power allocation and a second parameter relating only to code allocation. The first parameter has a power allocation exponent and the second parameter has a code allocation exponent. Both the power allocation exponent and the code allocation exponent are data stream dependent.
