International Classification:
H04B 7/185
US Classification:
370318, 370478, 455 134, 455 23, 455 60
Abstract:
The present invention involves apparatus and methods to perform wireless terminal transmission power control. The invention uses novel and highly efficient methods to: convey power control information, specify power control level adjustments, recognize power control information, limit interference in the power control signaling, and recognize corrupted power control signaling, thus conserving wireless terminal energy and minimizing power control signaling and associated bandwidth. Base stations send analog power control command signals, with a continuous range of control levels, to wireless terminals for transmission power adjustments. Power control signals include two components which can be used to convey information, e. g. , power control commands, signal quality, device identity information. For zero power adjustment, the control component signal is not transmitted.

Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
H04B 7/06
US Classification:
455101, 455132, 4555621, 4552771
Abstract:
Transmit and/or receive diversity is achieved using multiple antennas. In some embodiments, a single transmitter chain within a wireless terminal is coupled over time to a plurality of transmit antennas. At any given time, a controllable switching module couples the single transmitter chain to one the plurality of transmit antennas. Over time, the switching module couples the output signals from the single transmitter chain to different transmit antennas. Switching decisions are based upon predetermined information, dwell information, and/or channel condition feedback information. Switching is performed on some dwell and/or channel estimation boundaries. In some OFDM embodiments, each of multiple transmitter chains is coupled respectively to a different transmit antenna. Information to be transmitted is mapped to a plurality of tones. Different subsets of tones are formed for and transmitted through different transmit chain/antenna sets simultaneously.

US Patent:
7711377, May 4, 2010
Filed:
Jun 10, 2004
Appl. No.:
10/865616
Inventors:
Rajiv Laroia - Basking Ridge NJ, US
Junyi Li - Bedminster NJ, US
Sundeep Rangan - Jersey City NJ, US
Prashanth Hande - Jersey City NJ, US
Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
H04Q 7/20
US Classification:
455458, 4554261, 455343, 455434, 455574, 370312, 370332, 370335
Abstract:
Methods and apparatus for efficient two-stage paging wireless communications systems are described. Wireless terminals are assigned to paging groups. A few first paging message information bits are modulated (using non-coherent modulation) into a first paging signal and communicated from a base station to wireless terminals. WTs wake-up, receive the first paging signal and quickly ascertain whether its paging group should expect a second paging signal, if so, the WT is operated to receive the second paging signal; otherwise, the WT goes back to sleep conserving power. The base station modulates (using coherent modulation) a number of second message information bits into a second paging signal and transmits the signal to WTs. From the information in first and second paging signals, a WT can determine that it is the paged WT and process the paging instructions. The intended paged WT can transmit an acknowledgement signal on a dedicated uplink resource.

Inventors:
Arnab Das - Summit NJ, US
Prashanth Hande - Somerset NJ, US
Sundeep Rangan - Jersey City NJ, US
Xinzhou Wu - Urbana IL, US
Juergen Cezanne - Ocean Township NJ, US
Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
G08C 17/00
US Classification:
370311, 370318, 370328, 370316, 370248, 455522, 455 69
Abstract:
Systems and methodologies are described that facilitate utilizing power-based rate signaling for uplink scheduling in a wireless communications system. A maximum nominal power (e. g. , relative maximum transmit power that may be employed on an uplink) may be known to both a base station and a mobile device. For example, the base station and the mobile device may agree upon a maximum nominal power. According to another example, signaling related to a maximum nominal power for utilization on the uplink may be provided over a downlink. Further, selection of a code rate, modulation scheme, and the like for the uplink may be effectuated by a mobile device as a function of the maximum nominal power. Moreover, such selection may be based at least in part upon an interference cost, which may be evaluated by the mobile device.

Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
H04K 1/10
US Classification:
375260, 375295, 375280, 455 61, 455102, 455561, 370312, 370349, 370432, 370471
Abstract:
User specific modulation-symbol scrambling is implemented for various uplink segments, e. g. , uplink traffic acknowledgement channel (ULTACH), uplink state request channel (ULSRCH), and uplink dedicated control channel (ULDCCH) segments. A wireless terminal is assigned a wireless terminal scrambling identifier. A set of ordered input modulation symbols are determined for an uplink dedicated segment to which user specific scrambling is to be applied. One bit of the assigned wireless terminal scrambling identifier is associated with each of the ordered input modulation symbols of a segment in accordance with a predetermined mapping. For each input modulation symbol a scrambling operation, e. g. , a phase rotation of the input modulation symbol, is performed as a function of the associated user specific scrambling identifier bit to obtain a corresponding output modulation symbol. A value of (0,1) for a scrambling ID bit is associated with a (first, second) amount of phase rotation, e. g.

Opportunistic Uplink Scheduling

US Patent:
8160007, Apr 17, 2012
Filed:
Nov 20, 2007
Appl. No.:
11/943512
Inventors:
Xinzhou Wu - Monmouth Junction NJ, US
Sundeep Rangan - Jersey City NJ, US
Prashanth Hande - Somerset NJ, US
Arnab Das - Summit NJ, US
Junyi Li - Bedminster NJ, US
Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
H04W 4/00
US Classification:
370329, 370341
Abstract:
Systems and methodologies are described that facilitate scheduling uplink transmissions. For instance, a time sharing scheme can be utilized such that differing mobile devices can be scheduled to transmit during differing time slots; however, it is also contemplated that a static scheme can be employed. Pursuant to an illustration, an interference budget can be combined with a time varying weighting factor associated with a base station; the weighting factor can be predefined and/or adaptively adjusted (e. g. , based upon a load balancing mechanism). Moreover, the weighted interference budget can be leveraged for selecting mobile devices for uplink transmission (e. g. , based at least in part upon path loss ratios of the mobile devices). Further, disparate interference budgets can be utilized by differing channels of a sector at a particular time. Also, for example, a base station can assign a loading factor to be utilized by wireless terminal(s) for generating channel quality report(s).
