  • Publication number: 20110116563
    Abstract: A method of wireless communication includes utilizing a first outer loop for single-stream transmissions when a requested PCI by a UE is within a first set. The utilizing the first outer loop includes utilizing a first outer loop margin to adjust a size of a transport block by a first backoff margin when the UE requests a PCI within the first set. The method further includes utilizing a second outer loop for single-stream transmissions when the requested PCI by the UE is within a second set different from the first set. The utilizing the second outer loop includes utilizing a second outer loop margin to adjust the size of the transport block by a second backoff margin when the UE requests a PCI within the second set.

  • Publication number: 20100322090
    Abstract: A method for wireless communications is provided. The method includes applying independent power controls to two or more carriers from a set of high speed packet access signals. The method includes monitoring power across the two or more carriers to determine power levels for the set of high speed packet access signals. The method also includes automatically scaling at least one of the independent power controls in view of the determined power levels for the set of high speed packet access signals. The method also includes setting the minimum power offset of the data channel independently on each carrier.

  • Publication number: 20100202393
    Abstract: This innovation relates to systems and methods for multiple carrier allocation in wireless communication networks, and more particularly to allocation and/or de-allocation of one or multiple carriers on the uplink to a high-speed uplink packet access user. A radio network controller can allocate uplink carriers to users based on a plurality of criteria, including but not limited to network loading, channel conditions, and so forth. The allocation messages can be transmitted to the user via layer three messages or layer one signaling.

  • Publication number: 20100202392
    Abstract: Systems and methodologies are described that facilitate split a common total power resource among a plurality of carriers. A power distribution scheme can be employed jointly across the plurality of carriers to determine an amount of power to allocate to respective carriers. Based upon an amount of power allocated, a packet format can be selected for each carrier based upon the amount of power allocated to the carrier and/or a serving grant associated with the carrier.

  • Publication number: 20090245212
    Abstract: Techniques for reporting acknowledgement (ACK) information and channel quality indication (CQI) information in a wireless communication system are described. A user equipment (UE) may be able to receive data from up to two cells with dual-cell operation. The UE may determine CQI information for a first cell, determine CQI information for a second cell, and send the CQI information for both cells on a feedback channel with a single channelization code. The UE may process a control channel from each cell and, if control information is received from the cell, may further process a data channel from the cell to receive data sent to the UE. The UE may determine ACK information for each cell based on processing results for the data and control channels from that cell. The UE may send the ACK information for both cells on the feedback channel with the single channelization code.

  • Publication number: 20090213805
    Abstract: Techniques for supporting data transmission on multiple carriers in a wireless communication system are described. A user equipment (UE) may determine available transmit power for data transmission on multiple carriers. The UE may distribute the available transmit power to multiple carriers (e.g., using uniform power distribution, greedy filling, water filling, etc.) to obtain allocated transmit power for data for each carrier. The UE may send at least one resource request with information indicative of the allocated transmit power for each of the multiple carriers to a Node B. The UE may receive at least one resource grant with information indicative of granted transmit power for each of at least one carrier, which may be all or a subset of the multiple carriers. The UE may send data on the at least one carrier and may limit its transmit power for each carrier to the granted transmit power for that carrier.
