  • Publication number: 20090303978
    Abstract: A symbol multiplied by a first constant amplitude zero autocorrelation code CAZAC reference signal RS is transmitted in a timeslot from a first antenna of a user equipment on a first physical uplink control channel in a manner that multiplexes with other user equipments. A symbol multiplied by a second CAZAC RS is transmitted in the timeslot from a second antenna of the user equipment on a second physical uplink control channel in a manner that multiplexes with other user equipments. The first and second CAZAC RSs are orthogonal to one another by at least one of the cyclic shifts or a cover code applied to at least one of the first and the second CAZAC RSs. The symbols may be the same or different, and may represent an ACK, a NACK, or a scheduling request indicator. These teachings extend to more than two transmit antennas.

  • Publication number: 20090219897
    Abstract: A method for signaling between a mobile apparatus (10) and a network node (12) is described. The method includes generating a message that includes a scheduling request. Determining whether a second indication (e.g., an acknowledgment) is to be transmitted in a sub-frame with the first indication is also included. The method includes, in response to a determination that the second indication is not to be included, the message is configured in a first configuration and, in response to a determination that the second indication is to be included, the message also includes the second indication and the message is configured in a second configuration. The first configuration is distinct from the second configuration. The method also includes sending the message, via a wireless transmitter, in the sub-frame. Apparatus and computer-readable media are also described.

  • Publication number: 20090181687
    Abstract: A method, apparatus, and computer program embodied on a computer-readable medium to create an uplink message to be transmitted to a base station, the created uplink message comprises a sounding reference signal based on accessed data. An uplink scheduling grant signal is received via downlink, from the base station, in response to the transmission of the uplink message. An uplink data transmission is transmitted to the base station responsive to the received uplink scheduling grant signal.

  • Publication number: 20080298433
    Abstract: A cyclic shift of a reference signal is quantized as a combination of a cell specific cyclic shift with an outcome of a pseudo-random hopping, and an indication of the cell specific cyclic shift is broadcast in the cell. In one embodiment the cyclic shift is quantized as a modulo operation on a sum of the cell specific cyclic shift, the outcome of the pseudo-random hopping, and a user specific cyclic shift, in which case an indication of the user specific cyclic shift is sent in an uplink resource allocation and a user sends its cyclically shifted reference signal in the uplink resource allocated by the uplink resource allocation. The cyclic shift may also be quantized according to length of the reference signal as cyclic_shift_symbol=(cyclic_shift_value*length of the reference signal)/12; where cyclic_shift_value is between zero and eleven and cyclic_shift_symbol is the amount of cyclic shift given in reference signal symbols.

  • Publication number: 20080165903
    Abstract: A detect decision is made by non-coherently combining results from correlating a preamble (CAZAC) sequence with base/root sequences used in the cell and setting a detection threshold based on those combined results. Another threshold can be set based on coherently combining results from correlating the preamble sequence, in which case the detect decision is based on satisfying either one of the thresholds. Where the sequence repeats in the same preamble, the results that are combined are from correlating the first instance of the CAZAC sequence and from correlating the second instance of the CAZAC sequence. Where the sequence does not repeat, different segments of the CAZAC sequence, each less than the whole and not necessarily of the same length, are correlated for a partial correlation on each segment, then the segments are combined and used to set the detection threshold.

  • Publication number: 20080089403
    Abstract: Disclosed is a chip-level or a symbol-level equalizer structure for a multiple transmit and receiver antenna architecture system that is suitable for use on the WCDMA downlink. The equalizer structure takes into account the difference in the natures of inter-antenna interference and multiple access interference and suppresses both inter-antenna interference and multiple access interference (MAI). Enhanced receiver performance is achieved with a reasonable implementation complexity. The use of the CDMA receiver architecture, in accordance with this invention, enables the realization of increased data rates for the end user. The CDMA receiver architecture can also be applied in conjunction with space-time transmit diversity (STTD) system architectures.

  • Publication number: 20080070586
    Abstract: The guard band between two carriers of the same or different operators is reduced or dynamically adjusted by initiating a dynamic change request of the guard band between the two carriers to allow for flexible spectrum use by adjusting the tolerable guard band overlap. The data is distributed or positioned in the carrier spectrum band as a function of the Quality of Service so that the lowest Quality of Service constrained data are positioned at the edges of the carrier spectrum band and the highest Quality of Service constrained data are positioned in the middle of the carrier spectrum band to minimize any impact from the increased adjacent channel interference due to the guard band overlap and narrower guard band.
