Abstract: A data packet structure conveys data of service data units (SDU) using protocol data units (PDU). The data packet structure includes a data packet payload having at least one protocol data unit (PDU). A protocol data unit (PDU) includes a service data unit (SDU) or a fragment of a service data unit and a data packet header including an indicator indicating whether or not the data packet payload begins with a protocol data unit (PDU) being a fragment of a service data unit and whether or not the data packet payload ends with a protocol data unit (PDU) being a fragment of a service data unit.

Abstract: A wireless terminal (30) capable of operating in a discontinuous mode and method for operation facilitate measurements pertaining to position of the wireless terminal (30). A measurement request message from a radio access network (28) indicates that measurements are to be performed by the wireless terminal on downlink signals transmitted by the base station or by the base station on downlink signals transmitted by the base station. As a result of or after receiving the message, operation of the wireless terminal (30) changes from a discontinuous mode to a modified mode to facilitate performance of the measurements. Relative to the discontinuous mode at least one of following are shortened or eliminated in the modified mode: (i) the non-reception periods, and (ii) the non-transmission periods.

Abstract: Provided is a radio communication device which can suppress inter-code interference between an ACK/NACK signal and a CQI signal which are code-multiplexed. A diffusion unit (214) diffuses the ACK/NACK signal inputted from a judgment unit (208) by using a ZC sequence. A diffusion unit (219) diffuses the CQI signal by using a cyclic shift ZC sequence. By using a Walsh sequence, a diffusion unit (216) further diffuses the ACK/NACK signal which has been diffused by using the ZC sequence. A control unit (209) controls the diffusion unit (214), the diffusion unit (216), and the diffusion unit (219) so that the minimum value of the difference between the CQI signals from a plurality of mobile stations and a cyclic shift amount of the ACK/NACK signal is not smaller than the minimum value of the difference between the cyclic shift amounts of the ACK/NACK signals from the plurality of mobile stations.

Abstract: Integrated circuitry for use in a mobile radio station includes a receiver that receives control information and a data processor coupled to the receiver. The data processor provides a number of different sequences that are derived from a base sequence. The different derived sequences are respectively associated with different amounts of data or reception qualities, have different cyclic shifts, and are arranged in an increasing order of the cyclic shifts. The data processor randomly selects a sequence from a subset of the derived sequences. The subset of derived sequences depends on the control information.

Abstract: A method in a Just-In-Time, JIT, compiler for compiling code in a JIT-compiler for a heterogeneous multiprocessor system is provided. The method comprises compiling a snippet of input code, whereby one or more compiled code snippets are generated for the snippet of input code. The one or more compiled code snippets are tagged with one or more snippet specific characteristics. One or more compiled code snippets are selected from the compiled code snippets, based on said snippet specific characteristics. The one or more selected compiled code snippets are executed on one or more of the plurality of processors. While executing, run-time data is gathered, where the gathered data is tagged for which processor in the heterogeneous multiprocessor system it is related to.

Abstract: Random access technology is provided for establishing an individual channel between a radio communication terminal device and a base station device in a short time and a radio communication terminal device executing the random access method. A RACH sub-channel allocation unit allocates a transmission packet input from a replication unit to an arbitrary sub-carrier at the RACH arbitrary time slot at random. An allocation unit judges whether an overlap is generated in the allocation result obtained by the RACH sub-channel allocation unit.

Abstract: A method is provided in a receiving node for handling status information of data units transmitted from a sending node to the receiving node over a radio link. The receiving node establishes (401) that a number of data units that has been transmitted by the sending node are missing. The receiving node sends (402) a reduced status message to the sending node over the radio link, which message is reduced such that it comprises the negative acknowledgement for a first part of missing data units and omits negative acknowledgements for the rest of the missing data units. The omitted negative acknowledgement for the rest of the missing data units will not erroneously be interpreted as correctly received data units by the sending node.
