摘要： Systems and methods for communicating over multiple carriers are described herein. A predetermined event triggers the generation of scheduling information for two or more of the carriers. The predetermined event may comprise expiration of a timer set for at least one of the two or more carriers, storing data in a buffer having a higher transmission priority than data previously stored in the buffer, or changing at least one of the two or more carriers from being served by a first cell to being served by a second cell.

摘要： In a wireless communication system in which a user using a mobile equipment requests a serving cell handoff from a source cell to a target cell, the mobile equipment monitors authorization for the handoff from the target cell. At the same time, the mobile equipment can decode data from either the source cell or the target cell. Upon receipt of authorization for the handoff, the mobile equipment sends confirmation of the handoff to the target cell.

摘要： In an embodiment, a user equipment (UE) determines that a client application has entered a period of transmission inactivity whereby the UE will not be required to transmit data on behalf of the client application. The UE selectively transmits a transmission inactivity notification to an access network (AN) to notify the AN of the transmission inactivity period. The AN receives the transmission inactivity notification and determines to transition the UE from a first state to a second state based at least in part on the received transmission inactivity notification, the second state associated with lower-power consumption of the UE than the first state. The AN sends instructions to the UE to facilitate the transition of the UE from the first state to the second state. In another embodiment, the AN can send instructions to the UE to prohibit the UE from sending transmission inactivity notifications.

摘要： Systems and methodologies are described that facilitate dynamic load balancing in a communications network. In particular, one or more mobile devices can send random access preambles on an uplink frequency paired to a downlink frequency employed to connect the one or more mobile devices to a base station. The base station can determine if an uplink frequency load imbalance exists based upon the random access preambles. The base station can transmit an indicator on an acquisition indicator channel to at least one mobile device wherein the indicator includes a command to transition to a new uplink frequency. The mobile device can switch uplink frequencies in response to the command.

摘要： Techniques to support operation in a compressed mode and/or a continuous packet connectivity (CPC) mode are described. In an aspect, a user equipment (UE) may obtain an assignment of enabled subframes for the CPC mode and an assignment of transmission gaps for the compressed mode. The transmission gaps may be aligned with idle times between the enabled subframes. The UE may exchange data during enabled subframes not overlapping the transmission gaps and may skip data exchanges during enabled subframes overlapping the transmission gaps. The UE may make cell measurements during the transmission gaps. In another aspect, the UE may obtain enabled subframes and skipped subframes, exchange data during enabled subframes not corresponding to the skipped subframes, and skip data exchanges during the skipped subframes. In yet another aspect, the UE may receive orders on a shared control channel to quickly enable and disable the compressed mode.

摘要： Techniques for performing power control during discontinuous transmission (DTX) operation are described. A UE transmits on the uplink during a transmission burst and receives TPC commands generated by a Node B based on the uplink transmission. The UE may receive two TPC commands at the end of the transmission burst that are not applied during the transmission burst. The UE saves and applies these two TPC commands in the next transmission burst. In one design, the UE applies each saved TPC command in one slot of the next transmission burst. In another design, the UE combines the two saved TPC commands and applies the combined value in the first two slots of the next transmission burst. In yet another design, the UE selects one of the saved TPC commands and applies the selected TPC command in the first two slots of the next transmission burst.

摘要： Synchronization of uplink carriers for transmission is disclosed in accordance with different aspects. The uplink carriers that transmit information are configured such that at least one of the uplink carriers is an anchor carrier. When a plurality of carriers are thus configured for the uplink, they are synchronized such that they bear a predetermined phase relationship with each other. The predetermined phase relationship between the plurality of carriers depends on the transmit timing of the anchor carrier or a combination of transmit timings of the anchor carrier and one or more non-anchor carriers comprised within the uplink carriers.

摘要： Method and apparatus for hashing mobile stations to frequencies in a communication system. The method uses two-level hashing to assign a mobile station first to frequency band and then to a specific frequency within the frequency band. Embodiments allow for weights to be assigned to frequencies and mobiles hashed to the weighted frequencies. Weighting allows for a non-uniform distribution of mobile stations among frequencies to optimize system operating parameters.

摘要： A small base node such as a Home Base Node (HNB), or femto cell, may reduce its transmit power in order to prevent co-channel or adjacent channel interference, or to limit its coverage area. Once the power is set, the HNB signal to a served Home User Equipment (HUE) its transmit Common Pilot Channel (CPICH) transmit power for accurate path loss estimation. When this power is outside of the permissible range, the HNB adjusts other parameters (such as Random Access Channel (RACH) constant value) to compensate for the error in signaled CPICH power, and thus compensate in that process the error in determining path loss. Similarly, if the uplink sensitivity is adjusted, to prevent interference, parameters would also be adjusted and signaled to the HUE to reflect the link imbalance.
