Abstract: A method for performing burst mapping on transmission data by a transmitter in a mobile communication system using a 16-ary Quadrature Amplitude Modulation (16-QAM) modulation scheme is disclosed. The burst mapping method includes generating control information bits and user data bits by encoding input control information and user data; dividing the control information bits and user data bits into more than two bursts; and arranging a Training Sequence Code (TSC) in a center of each burst, placing the coded control information bits in positions adjacent to the TSC, and swapping the user data bits with bits mapped to higher-reliability positions among the control information bits.

Abstract: A method and apparatus are provided for jointly encoding bits containing information about an existing modulation technique or an existing antenna transmission technique in order to extend signaling to include new information about an additional modulation technique or the use of an additional antenna transmission technique without having to increase the number of bits transmitted in the signaling; and conveying the new information in unused combinations of the encoded bits. The signaling may take the form of a high speed shared control channel (HS-SCCH) that forms part of a high speed downlink packet access (HSDPA). In some embodiments, the existing modulation technique may include quadrature phase shift keying (QPSK), 16 quadrature amplitude modulation (16QAM), or some combination thereof, and the additional modulation technique may include 64 quadrature amplitude modulation (64QAM).

Abstract: A method and system for supporting voice over Internet protocol (VoIP) services over a wireless communication network are disclosed. Data is encoded at a coding rate specified by a controller for generating a VoIP packet. Among the encoded data, bits sensitive to errors and bits not sensitive to errors are identified and error protection is performed separately by a medium access control layer and/or physical layer. A header of the VoIP packet may be selectively compressed in accordance with an indication from the controller. A user datagram protocol (UDP)-Lite may be used for partial coverage of the sensitive bits. A comfort noise may be generated by a receiving end during a silence period without receiving a comfort noise packet from a transmitting end. If the VoIP packet is not fit into a currently assigned radio resource, the VoIP packet may be fragmented.

Abstract: The writing address supply part 210 supplies writing addresses for writing the bits forming bit sequences corresponding to the header H contained in a frame to be transmitted or stored and bit sequences corresponding to the data D, into the operating memory 220. The reading address supply part 230 alternately supplies to the operating memory 220 a plurality of addresses for reading a plurality of continuous bits corresponding to the header H from the operating memory 220, and an address for reading 1 bit corresponding to the data D from the operating memory 220, and reads the bit sequence such that the bits forming the bit sequence corresponding to the header H are scattered and arranged within the bit sequence forming the data D, from the operating memory. In accordance with such an interleaving device, it is possible to individually randomize frames according to their constituent data, and it is possible to transmit the bits that make up such data in a format which is most suited for said data.

Abstract: According to an aspect, a transmitting device determines, for each of a plurality of transmissions, whether user data to be transmitted within a time transmission interval, TTT, will be closest in time to a DMRS transmitted before the user data or after the user data. If before the user data, all HARQ ACK/NACK data for the transmission is mapped to the earliest in time SC-FDMA symbol carrying user data in the transmission, and to pre-DFT symbols closest in time to the DMRS transmitted before the user data. If after the user data, all HARQ ACK/NACK data for the transmission is mapped to the last in time SC-FDMA symbol carrying user data in the transmission, and to pre-DFT symbols closest in time to the DMRS transmitted after the user data. SC-FDMA signals are formed from user data and control information for the transmission, based on the mapping.

Abstract: A method, apparatus, and computer program for controlling allocation of control message fields in uplink transmission in a cellular telecommunication system are presented. Uplink control message fields are allocated to the resources of a physical uplink shared traffic channel according to an uplink transmission scheme selected for a user terminal.

Abstract: Systems, methods, and instrumentalities are disclosed for receiver feedback in wireless systems. Receiver feedback format, content, type and/or timing may be determined as a function of, for example, at least one of a type of soft-combining processing to apply in a HARQ process, a HARQ operating point for the HARQ process, one or more reference transmissions for controlling a type of HARQ feedback for the HARQ process, and a feedback suppression parameter for one or more transmissions in a sequence associated with the HARQ process or a transport block (TB). Uniform and non-uniform CB-to-CBG mapping may be provided (e.g., by a WTRU) based on, for example, one or more parameters, interference and channel conditions and/or a probability of or actual pre-empting transmissions. A CB to CBG mapping indication may be provided, for example, in support of selecting a CB to CBG mapping from multiple CB to CBG mappings. Intra- and inter-WTRU interference/preemption indications may be provided.
