摘要： 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 that a number of data units that has been transmitted by the sending node are missing. The receiving node sends 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.

摘要： A method for transmitting uplink signals, which include ACK/NACK signals, control signals other than the ACK/NACK signals, and data signals, is disclosed. The method comprises serially multiplexing the control signals and the data signals; sequentially mapping the multiplexed signals within a specific resource region in accordance with a time-first mapping method, the specific resource region including a plurality of symbols and a plurality of virtual subcarriers; and arranging the ACK/NACK signals at both symbols near symbols to which a reference signal of the plurality of symbols is transmitted. Thus, the uplink signals can be transmitted to improve receiving reliability of signals having high priority.

摘要： A random access procedure between a mobile terminal and a network is performed based upon the characteristics of a RACH preamble transmitted by the terminal. A first type of random access preamble is selectable by the terminal from a set of random access preambles, and a second type of random access preamble is directly allocated to the terminal by the network. The network responds with a random access response. The terminal performs a discontinuous reception (DRX) operation that allows it to monitor a downlink control channel discontinuously. The DRX operation includes an active time period during which the terminal monitors the control channel after successful reception of the random access response for the second type of random access preamble until a transmission from the network addressed to a Cell-Radio Network Temporary Identifier (C-RNTI) associated with the terminal is received.

摘要： A User Equipment (UE) receives a Physical Downlink Control Channel (PDCCH) at subframe k and decodes at the subframe k a set of PDCCH candidates including L control channel elements (CCEs). The L CCEs are contiguously located from a position given by using a variable of Yk and a modulo (N/L) operation, where N represents a total number of CCEs in the subframe k, Yk is defined by Yk=(A*Yk−1)mod D, and A and D are predetermined constant values. When k=0, Y−1 is determined based on a UE identifier having 16-bits.

摘要： A symbol mapping method for repetition coding is disclosed. The symbol mapping method comprises performing repetition coding on codeword to output repeated codeword symbols, and mapping the repeated codeword symbols with subcarriers located in different localized resource blocks. According to the embodiments of the present invention, it is possible to obtain maximum reliability in a receiving side by mapping codeword bits with subcarriers to reduce the number of bits having low reliability when a transmitting side uses repetition coding. Also, it is possible to improve decoding throughput and obtain channel diversity.

摘要： A user equipment (UE) receives downlink data using resource blocks in a wireless mobile communication system. The UE includes data processing circuitry coupled to a receiver that receives downlink control information including resource allocation information for the downlink data from a base station and to receive the downlink data mapped to physical resource blocks (PRBs) based on the downlink control information. The resource allocation information indicates virtual resource block (VRB) allocations for the user equipment. Each resource block corresponds to one time slot. A resource block pair includes a first resource block associated with a first time slot and a second resource block associated with a second time slot adjacent to the first time slot. The first and second resource blocks are allocated to the same frequency indices. A mapping relationship between VRB pairs and PRB pairs exists such that frequency consecutive VRB pairs are mapped to non-frequency consecutive PRB pairs and that each resource block pair is split so there is a frequency gap between the first and second parts of the resource block pair. The resource allocation information indicates the frequency gap size is one of a first value and a second different value.

摘要： A user equipment receives configuration information from a base station in a wireless communication system. Radio signals carrying configuration control information are received by a user equipment (UE) that includes an ACK/NACK feedback mode indicator. The UE also receives downlink subframes. The ACK/NACK feedback mode indicator is processed to determine if the ACK/NACK feedback mode indicator indicates the user equipment should (a) send an ACK/NACK signal in a one-to-one mapping between a downlink subframe and a corresponding uplink ACK/NACK signal or (b) send an ACK/NACK signal in an N-to-one mapping between N downlink subframes, where N is an integer greater than one, and a corresponding single uplink ACK/NACK signal. One or more ACK/NACK signals is transmitted in accordance with the determination of the processor.

摘要： In a wireless mobile communication system, user equipment receives downlink data and downlink control information including resource allocation information for the downlink data from a base station. Downlink data is mapped to physical resource blocks (PRBs) based on the downlink control information. The resource allocation information indicates virtual resource block (VRB) allocations for the user equipment. Indexes of PRBs to which the downlink data are mapped are determined based on mapping relationship between VRBs and the PRBs. The mapping relationship is defined such that indexes of the VRBs are mapped to indexes of the PRBs for a first part and a second part of a subframe. The received downlink control information includes control information that determines whether the indexes of the PRBs for the second part are separated with respect to the indexes of the PRBs for the first part based on a predetermined gap in a distributed mode where distributed VRBs are used or whether the indexes of the PRBs for the second part are not separated with respect to the indexes of the PRBs for the first part in a non-distributed mode where localized VRBs are used.
