  • Patent number: 8023988
    Abstract: Techniques to more efficiently control the transmit power for a data transmission that uses a number of formats (e.g., rates, transport formats). Different formats for a given data channel (e.g., transport channel) may require different target SNIRs to achieved a particular BLER. In one aspect, individual target BLER may be specified for each format of each data channel. In another aspect, various power control schemes are provided to achieve different target SNIRs for different formats. In a first power control scheme, multiple individual outer loops are maintained for multiple formats. For each format, its associated outer loop attempts to set the target SNIR such that the target BLER specified for that format is achieved. In a second power control scheme, multiple individual outer loops are maintained and the base station further applies different adjustments to the transmit power levels for different formats.

  • Patent number: 7970425
    Abstract: A push-to-talk (“PTT”) group call system, for use as, e.g., a public safety wireless network, includes a CDMA-based 1x-EVDO radio access network operably connected to a PTT server over an IP network. The radio access network includes base stations for radio communications with a number of distributed mobile stations. In carrying out wireless communications, the group call system combines IP-based voice and other real-time multimedia services with the 1x-EVDO radio access network's Broadcast Multicast Service. This allows a number of users to receive the same copy of an IP-based media stream for point-to-multipoint, group transmissions. To reduce call setup times, the group call system uses “standing” call groups, which are ongoing group communication channels pre-established between the PTT server and authorized group users. Thus, mobile stations link to one or more standing call groups of interest upon power-up, prior to users speaking.

  • Patent number: 7957760
    Abstract: The distance between a first Multi Band Orthogonal Frequency Division Multiplex (MB-OFDM) data transceiver and a second or more such transceiver is determined using known techniques. The radio frequency path loss between transceivers is estimated given said distance, using a known relationship between distance and path loss, and further accounting for line-of-sight or non-line-of-sight conditions if desired. This path loss value is added to the typically minimum transmit power level, absent path loss, needed for reliable data communication. This modified initial transmit power level is then used by the first transceiver to begin the known iterative feedback process of transmit power control (TPC). Because this modified initial transmit power level, based on distance, is closer to the final optimum level, convergence in the TPC process occurs in fewer steps and less time than had the initial transmit power been maximum power as is typical in known TPC systems.

  • Patent number: 7957759
    Abstract: Embodiments of the invention provide methods for transmitting reference signals (RS) from user equipments (UEs) in wireless communication systems. These RS are used, among other functions, by a serving base station to schedule data transmission from UEs and perform power and timing control of the UE signal transmissions. The RS are constructed based on constant amplitude zero autocorrelation (CAZAC) sequences, including their possible modifications. The invention describes methods to multiplex transmission of RS from multiple UEs by having the serving base station control the CAZAC sequence and the associated cyclic shift, transmission bandwidth, transmission period, and transmission power applied to the RS transmission by each UE.

  • Patent number: 7949357
    Abstract: In a first time interval TI a first frequency band FB is pseudorandomly selected from a designated spectrum, and a first analysis result is determined by sensing the first FB during the first TI and then transmitted. In a second TI a second FB is pseudorandomly selected from the designated spectrum, and a second analysis result is determined by sensing the second FB during the second TI and then transmitted. Where multiple devices do this the entire spectrum is sensed, each band by a subset of devices that changes at each TI, and so any unused or underutilized spectrum is searched by the collaborative spectrum sensing, which avoids propagation problems such as fading. Also, a central node can assure various collaborating users report different FBs in different TIs such that the subset of reporting users changes for at least one of the bands in each subsequent reporting TI. Sensing and communication can be performed in different portions of the same network defined transmission time interval.
