Abstract: Aspects of resolving conflicting configuration parameters during wireless communication include triggering reselection to a new cell from a current cell and determining that a user equipment (UE) is configured in a forward access channel (FACH) state and is waiting for a Layer 2 Acknowledgement (L2 ACK) message from a network entity when reselection to the new cell is triggered. Further, the aspects include performing a collision resolution procedure in response to the determination that the UE is configured in the FACH state and is waiting for the L2 ACK message. In some aspects, the collision resolution procedure establishes which one of a plurality of information elements (IEs) to choose for a reconfiguration procedure.

Abstract: A gain factor is used for calculating one transmit power relative to another transmit power. For example, in UMTS high speed uplink packet access, a gain factor called βed is employed for transmission associated a given enhanced transport format combination indicator (E-TFCI). Conventionally, a gain factor to be used for a given E-TFCI can be determined via interpolation between two of the reference E-TFCIs to reduce signaling overhead. However, certain network configurations may result in one or more of the reference E-TFCIs that could be otherwise be used according to conventional techniques being outside of a valid range. In the event such a sub-optimal configuration occurs, interpolation and/or extrapolation schemes based on at least one reference E-TFCIs that is within and/or or is not within the valid range are used to calculate a gain factor for a given E-TFCI.

Abstract: In aspects for controlling transmit power of dual carrier uplink transmission for wireless communications, a user equipment (UE) determines presence of transmit power imbalance between a first and second radio frequency (RF) carrier of respective dedicated physical control channels for uplink transmission. The UE determines an estimate of a remaining available transmit power after estimating the transmit power used by each of the dedicated physical control channels. The UE allocates the estimated remaining available transmit power to the first and second RF carrier respectively based on both a size of data granted for uplink transmission on each RF carrier and on an effective power per bit on each RF carrier. Additionally, the UE determines a higher reliability value for each RF carrier based on a lower data error rate, identifies priority values for data to be transmitted and sends higher priority data over the RF carrier with higher reliability value.

Abstract: Techniques for prioritizing non-scheduled data are described. Non-scheduled data to be transmitted on a non-scheduled MAC-d flow having a non-scheduled priority and scheduled data to be transmitted on a scheduled MAC-d flow having a scheduled priority may be identified by a user equipment (UE). The UE may transmit the non-scheduled MAC-d flow and the scheduled MAC-d flow according to a priority condition. In one aspect, the UE may receive a pre-allocation of power associated with a non-empty non-scheduled MAC-d flow. Based on a priority condition that the non-scheduled priority is a highest priority, the UE may apply all of the pre-allocation of power when transmitting the non-scheduled MAC-d flow. In one aspect, based on a priority condition that the non-scheduled priority is a lower priority, the UE may adjust the non-scheduled priority and/or the scheduled priority so that the non-scheduled priority is a higher priority.

Abstract: The present disclosure presents a method and apparatus for improving uplink (UL) performance at a user equipment (UE). For example, the method may include identifying a random access channel (RACH) preamble failure when the UE is communicating with a current serving cell of the UE, increasing transmission power of successive RACH preambles based at least on the identifying, comparing signals received on a downlink at the UE via a first path and a second path from the current serving cell of the UE, and determining that a RACH preamble failure problem exists at the UE based at least on the comparing of the signals received on the downlink and identifying of successive RACH preamble failures. As such, improved performance uplink (UL) performance at a UE may be achieved.

Abstract: A user equipment (UE) and a method of using the UE are provided for fulfilling a network's intent to increase or decrease the serving grant for the UE in spite of a deadlock condition that may otherwise prevent fulfillment of the network's intent. That is, upon determining the network's intent, the UE may alter its serving grant according the intent by altering the number of packets for transmission in a TTI.
