    Abstract: Systems and methodologies are described that facilitate pilot channel optimization schemes for high data rate communications transmissions. In various illustrative implementations, pilot channel operations can be monitored and controlled by an exemplary base station for one or more cooperating wireless terminals (e.g., user equipment) such that one or more power features of the one or more cooperating wireless terminals can be illustratively changed in response to one or more selected pilot channel operational conditions. In an illustrative operation, an exemplary base station can engage one or more selected pilot channel control operations as part of pilot channel optimization comprising a jump detection technique, operating power control on another channel other than the DPCCH, engaging in delayed power control, engaging in a soft-handoff power control in the instance of a boosted pilot channel, and resolving ambiguity in grant messages resulting from a pilot boost.

    Abstract: Techniques for performing power control during discontinuous transmission (DTX) operation are described. A UE transmits on the uplink during a transm ission burst and receives TPC commands generated by a Node B based on the up link transmission. The UE may receive two TPC commands at the end of the tra nsmission burst that are not applied during the transmission burst. The UE s aves and applies these two TPC commands in the next transmission burst. In o ne design, the UE applies each saved TPC command in one slot of the next tra nsmission burst. In another design, the UE combines the two saved TPC comman ds and applies the combined value in the first two slots of the next transmi ssion burst. In yet another design, the UE selects one of the saved TPC comm ands and applies the selected TPC command in the first two slots of the next transmission burst.

    Abstract: Techniques for utilizing multiple carriers to substantially improve transmission capacity are described. For multi-carrier operation, a terminal receives an assignment of multiple forward link (FL) carriers and at least one reverse link (RL) carrier. The carriers may be arranged in at least one group, with each group including at least one FL carrier and one RL carrier. The terminal may receive packets on the FL carrier(s) in each group and may send acknowledgements for the received packets via the RL carrier in that group. The terminal may send channel quality indication (CQI) reports for the FL carrier(s) in each group via the RL carrier in that group. The terminal may also transmit data on the RL carrier(s). The terminal may send designated RL signaling (e.g., to originate a call) on a primary RL carrier and may receive designated FL signaling (e.g., for call setup) on a primary FL carrier.

    Abstract: Techniques for reporting channel quality indicators (CQIs) are described. Data activity at a receiver may be determined, and CQI reporting by the receiver may be adjusted based on the determined data activity. In one design, CQI reporting may be enabled for a time window around each expected packet arrival for a periodic or quasi-periodic transmission and may be suspended outside of the time window. In another design, CQI reporting may be varied based on ACK/NACK feedback. In yet another design, CQIs may be sent at a first rate when data activity is not detected and at a second rate faster than the first rate when data activity is detected. In yet another design, CQIs may be sent only during discontinuous transmission (DTX) ON periods when data activity is not detected and may be sent during both DTX ON and OFF periods when data activity is detected.

    Abstract: Techniques for monitoring grant channels in a wireless communication network are described. In one design, a user equipment (UE) determines whether a monitoring condition is satisfied, monitors at least one grant channel for grants of radio resources if the monitoring condition is satisfied, and stops monitoring the at least one grant channel if the monitoring condition is not satisfied. The UE may determine that the monitoring condition is satisfied after sending scheduling information indicating that there is data to send, if there is an outstanding grant of radio resources, if a grant of radio resources is expected, if there is at least one scheduled flow and a data buffer for the scheduled flow(s) is not empty, if there is an outstanding grant of radio resources and data transmission has been sent using this grant of radio resources, if there is at least one other control channel to monitor, etc.
