摘要： Devices and methods for transmitting data on a radio channel comprise jointly encoding a preamble format with a first random access configuration, thereby forming an extended random access configuration represented by a set of bits. The first random access configuration comprises a combination of a density value and a version index. Each preamble format is associated with a plurality of version indexes.

摘要： A radio performs random access by receiving control information and grouping a predetermined number of sequences that are generated from a plurality of base sequences into a plurality of groups by partitioning the predetermined number of sequences. At least one of the groups is associated with a first respective range of data amounts and a first respective range of reception qualities. Sequences generated from a common base sequence are arranged in an increasing order of respective cyclic shifts associated with the sequences. A sequence is randomly selected from a plurality of sequences contained in one group of the plurality of groups. A position at which the predetermined number of sequences are partitioned is determined based on the control information. A number of sequences contained in each of the plurality of groups varies in accordance with the control information.

摘要： A wireless terminal (30) capable of operating in a discontinuous mode comprising and method for operating such wireless terminal (30) facilitate measurements pertaining to position of the wireless terminal (30). The method includes receiving a message from the radio access network (20). The measurement request message is configured to indicate 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. The method further comprises, as a result of or after receiving the message, changing operation of the wireless terminal (30) 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. “Changing from a discontinuous mode . . . to a modified mode” includes one or more of: (1) changing mode of the wireless terminal (e.g., changing from a discontinuous mode [such as discontinuous reception (DRX) or discontinuous transmission (DTX)] to a continuous transmission mode); (2) changing from the discontinuous mode (a first discontinuous mode) to a modified discontinuous mode (a second discontinuous mode).

摘要： The downlink control channels in a control region of each downlink subframe in a telecommunication system are divided into at least one common subset of the downlink control channels and a plurality of group subsets of the downlink control channels, such that the common subset or each common subset will be decoded by every user equipment, and each group subset will be decoded only by a limited group of user equipments. Resource assignment messages for a user equipment can then be transmitted on a downlink control channel of the relevant group subset, to avoid the need for messages to be decoded by a large number of UEs that will not act on them, while broadcast messages can be transmitted on a downlink control channel of the relevant common subset, to avoid the need for messages to be transmitted many times.

摘要： A user equipment for in use in a mobile communication system includes a receiver that receives control channel signaling including a new data indicator and a modulation and coding scheme field, and processing circuitry which determines that the new data indicator and the modulation and coding scheme field of the control channel signaling indicates a predetermined combination of a new data indicator value and a modulation and coding scheme index. The processing circuitry deactivates a semi-persistent resource allocation in response to determination that the new data indicator and the modulation and coding scheme field of the control channel signaling indicates a predetermined combination of a new data indicator value and a modulation and coding scheme index.

摘要： A terminal includes a decoder to decode a downlink control channel transmitted on one or more control channel element(s) (CCE(s)) in a search space including a plurality of CCEs. Processing circuitry in the terminal determines an uplink channel resource index based on the one or more CCEs, the uplink channel resource index having an association with a first uplink channel transmission spreading sequence and a second different uplink channel transmission spreading sequence. A transmitter transmits a response signal on an uplink channel using the first and second uplink channel transmission spreading sequences.

摘要： A mobile station comprises a receiver and a processor. The receiver is configured to receive, from a base station, allocation information indicating one or a plurality of allocated resource block(s) of uplink which are consecutive in a frequency domain. The processor is configured to determine, based on the allocation information, one of the resources of downlink, to which an ACK or NACK signal is distributively mapped onto a plurality of resource elements in subcarrier groups. The subcarrier resources within subcarrier group are consecutive in frequency domain and nonconsecutive in the frequency domain among subcarrier groups.

摘要： A method and transmission apparatus transmit broadcast system information in a mobile communication system. Further, a method and mobile terminal receive the broadcast system information. An improved method for broadcasting broadcast system information maps different partitions of broadcast system information to a shared transport channel or a broadcast transport channel for transmission. The mapping may take into account parameters inherent to the mobile terminals to which the broadcast system information is to be transmitted and/or parameters inherent to the different partitions of broadcast system information.
