Abstract: 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.

Abstract: 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.

Abstract: A semi-persistent resource scheduling (SPS) allocation of a user equipment is deactivated in an LTE-based mobile communication system without requiring changes to the Physical layer-to-MAC layer interface and/or changes to PDCCH formats agreed by the 3GPP. A combination of NDI value and MCS index is defined that commands release of SPS resources. An alternative solution proposed defines a special transport block size that when signaled in a PDCCH commands release of SPS resources.

Abstract: Apparatus for use in a mobile radio station includes a memory to store a table of adaptable associations between control information and code sequences. A data processor detects a condition and dynamically adapts one or more of the associations in the table stored in memory between control information and code sequences depending on the detected condition. A transmitter transmits one of the code sequences selected based on the dynamically adapted one or more of the associations.

Abstract: A wireless communication method and apparatus are provided for selecting quality-reporting sub-carrier bands based on sub-carrier band quantity information received from a base station. The method includes generally four steps. First, from a base station, information indicating quantity of sub-carrier bands is acquired. Second, channel quality of each of a plurality of sub-carrier bands within a communication band is measured from a received signal. Third, sub-carrier bands are selected from the plurality of sub-carrier bands, wherein quantity of the selected sub-carrier bands corresponds to the quantity of sub-carrier bands indicated by the acquired information. Fourth, information indicating channel quality of the selected sub-carrier bands is reported to the base station.

Abstract: A base station is provided for receiving an acknowledgement or negative acknowledgement (ACK/NACK) signal, including a transmitting unit configured to transmit a control signal using one or a plurality of CCE(s). The base station also includes a receiving unit configured to receive an ACK/NACK signal, the ACK/NACK signal being multiplied by an orthogonal sequence, by a sequence defined by a cyclic shift, and by either a first value or a second value, wherein the first value rotates a constellation of the ACK/NACK signal by 0 degrees and the second value rotates the constellation of the ACK/NACK signal by N degrees, which is different from 0 degrees.
