The present aspects relate to enabling a user equipment (UE) to operate in Dual Carrier mode during wireless communication, including generating an event trigger to be transmitted to a network entity in response to the UE satisfying a maximum transmit power threshold value, wherein generating the event trigger initiates a trigger timer that controls when to transmit the event trigger to the network. The aspects further include determining whether a plurality of optimization conditions are met, and modifying a transmission scheme based on the determination that the plurality of optimization conditions are met, wherein modifying the transmission scheme prevents the transmission of the event trigger to the network entity and resets the trigger timer.

Event 6D enhancements

Aspects related to allocating transmission power in wireless communications are described. It can be determined whether data is to be transmitted on an uplink control channel in one or more upcoming transmission time intervals (TTIs). Based on this determination, transmission power is allocated to an uplink enhanced dedicated channel in the one or more upcoming TTIs. Where uplink control channel data is not to be transmitted in the one or more upcoming TTIs, transmission power that would have been used for the uplink control channels can instead be allocated to the enhanced dedicated channel.

Techniques for optimizing transmission power allocation in wireless communications

Aspects described herein relate to transmitting hybrid automatic repeat/request (HARQ) data in continuous packet connectivity (CPC) mode. Data is transmitted to a network according to a discontinuous transmit (DTX) cycle in a CPC mode. The CPC mode can be exited, however, based at least in part on detecting available HARQ data for transmission. In this regard, a next transmission opportunity configured for transmitting the available HARQ data is determined, where the next transmission opportunity is not within a transmission time instance defined by the DTX cycle, and the available HARQ data is transmitted during the next transmission opportunity outside of the CPC mode.

Transmitting data outside of a discontinuous transmit (DTX) cycle in wireless communications

In an aspect, this disclosure provides for determining a power imbalance between a first radio frequency (RF) carrier and a second RF carrier of a dedicated physical control channel for uplink transmission, determining whether the power imbalance is greater than a power imbalance threshold, and blocking data transmission on one of the first RF carrier or the second RF carrier when the power imbalance is greater than the power imbalance threshold.

Aspects of the present disclosure provide for a method and an apparatus for wireless communications using an intelligent Random Access Channel (RACH) procedure that may increase the probability of obtaining an available E-DCH resource quickly in a Universal Mobile Telecommunication System.

Data is selectively transmitted over one or more carriers of a set of carriers. According to some aspects of the disclosure, a decision may be made to forgo the transmission of a preamble via one of the carriers (e.g., channels). For example, in a multi-carrier system, transmission of a preamble via one carrier may be inhibited if all of the data can be transmitted via another carrier. According to some aspects of the disclosure, a decision may be made to transmit different types of data on a single carrier rather than on multiple carriers. For example, a single carrier may be used to transmit schedule data and non-scheduled data if all of the data can be transmitted on one of the carriers (e.g., during a single transmission time interval). In this case, transmission of a preamble on another one of the carriers may therefore be inhibited.

Enhancements for transmission over multiple carriers

Methods and apparatus are described for improving call performance and data throughput. The methods and apparatus include receiving one or more packet data units (PDUs) during a transmission time interval (TTI) from a network entity, wherein the one or more PDUs are associated with a radio bearer. Further, the methods and apparatus include determining one or more out-of-order PDUs from the one or more PDUs. Moreover, the methods and apparatus include reordering the one or more out-of-order PDUs, wherein the one or more out-of-order PDUs are reordered within the TTI. Additionally, the methods and apparatus include processing the one or more reordered PDUs.

Disclosed are systems and methods for continuous inter-frequency measurement reconfigurations in a DC-HSUPA User Equipment (UE). In one aspect, the system may configure the UE to perform intra-frequency measurements on a frequency f1 and inter-frequency measurements on a frequency f2 in a dual carrier (DC) downlink (DL) mode and a single carrier (SC) uplink (UL) mode. The system may then reconfigure the UE to operate in a DC UL mode and continuing to perform inter-frequency measurements on the frequency f2 in the DC UL mode. The system may then reconfigure the UE to operate in the SC UL mode and continuing to perform inter-frequency measurements on frequency f2 in the SC UL mode.

Apparatus and methods for continuous inter-frequency measurement reconfigurations of DC-HSUPA UE

Techniques for prioritizing time critical data for transmission during a power-limited state in DC-HSUPA operation are described. A user equipment (UE) may be in a power-limited state. The UE may identify non-scheduled, time critical data and scheduled data as available for transmission. The UE may detect that a minimum transport block size is about to be selected for a transmission on a secondary uplink carrier. The UE may prioritize the non-scheduled, time critical data over the scheduled data and transmit the non-scheduled, time critical data on a primary uplink carrier based on the prioritizing. The UE also may transmit the scheduled data during a transmission time interval (TTI) that is different from the TTI during which the non-scheduled, time critical data was transmitted. The non-scheduled, time critical data and the scheduled data may be transmitted using transmit diversity.
