Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may monitor a narrowband (e.g., a single carrier, anchor carrier, etc.) for a control message that includes a grant for downlink data transmissions. The narrowband containing the control message may be a portion of a system bandwidth. The UE may then monitor a wideband (e.g., all or multiple carriers of the system bandwidth) for data according to the control message. Monitoring the wideband may include additional or alternate circuitry being powered (e.g., receiver circuit switching) to enable reception on an increased range of frequency spectrum. In some examples, a gap or narrowband data transmission may be scheduled between the control message and the grant to allow grant processing and receiver circuitry switching at the UE. In some cases, the control message and data transmission may be received in the same or different transmission time intervals (TTIs).

Abstract: Aspects described herein relate to configuring a discontinuous receive (DRX) mode in wireless communications. A transmission burst can be received over a communication frame, wherein the transmission burst includes a scheduling indication. A DRX OFF mode can be entered to suspend communication resources during at least an off period corresponding to a portion of a time period for the transmission burst based at least in part on the scheduling indication. A DRX ON mode can be entered to activate the communication resources during an on period corresponding to another portion of the time period subsequent to the off period defined for the transmission burst or a different time period subsequent to the time period defined for the transmission burst based at least in part on the scheduling indication.

Abstract: Reporting and measurements of measurement signals transmitted as a part of LTE/LTE-A networks that include contention-based spectrum is disclosed. In one aspect, a user equipment (UE) performs measurement signal thresholding by estimating the noise associated with the measurement signal. The UE would then use a measured parameter of that signal based on the measurement signal exceeding the threshold as a candidate for a valid measured parameter.

Abstract: Various aspects of the present disclosure provide for conditionally disabling discontinuous reception (DRX). For example, DRX may be disabled if there is a loss of DRX synchronization, a loss of signal radio bearer traffic, a poor radio frequency condition, a low signal-to-interference ratio estimate, a low transmit power condition, or a drop in transmit power. Various aspects of the present disclosure provide for determining that an access terminal and the network are not in synchronization (e.g., DRX synchronization), and attempting to re-synchronize the access terminal and the network. In cases where a loss of DRX synchronization involves one entity having DRX enabled while another entity has DRX disabled, DRX may be temporarily disabled until synchronization is restored. In cases where a loss of DRX synchronization involves different entities using different subframe indices, the subframe index used by one of the entities may be changed to restore synchronization.

Abstract: Techniques for uplink transmit power command (ULTPC) rejection threshold optimization in WCDMA for power control algorithm 2 (PCA2) are described. Uplink transmit power control commands may be received on a five-slot interval. The uplink transmit power control commands may be decoded for each of the five slots. The decoded uplink transmit power control commands may be compared for each of the five slots to a threshold. The threshold may be optimized to minimize overall transmit power control decision error. A bit decision may be made for each of the five slots based on the comparison and an overall transmit power control command may be determined based on the bit decision for each of the five slots over the five-slot interval.

Abstract: UEs are adapted to facilitate detection and handling of deconstructive impacts of default weight factors employed before downlink and uplink synchronization is achieved in closed-loop transmission diversity communications. According to one example, a UE may receive transmissions sent using a default weight factor for transmission diversity. The UE may determine whether the default weight factor is causing a deconstructive impact on signal-to-interference ratio estimates for the received transmissions. When it is determined that the default weight factor is causing the deconstructive impact on the signal-to-interference ratio estimates for the received transmissions, the UE may employ an alternate closed-loop transmission diversity (CLTD) mode. Other aspects, embodiments, and features are also included.

Abstract: UEs are adapted to facilitate calculation of signal-to-interference ratio (SIR) estimates in closed-loop transmission diversity (CLTD) communications before downlink and uplink synchronization is achieved. A UE may receive a transmission sent using transmission diversity. According to one example, the UE may calculate a plurality of signal-to-interference ratio (SIR) estimates for the received transmission, where each signal-to-interference ratio estimate is calculated using a different weight factor. The UE may further select one of the calculated signal-to-interference ratio (SIR) estimates to be employed for the received transmission. According to another example, the UE may calculate a signal-to-interference ratio (SIR) estimate for the received transmission without employing any weight factor. Other aspects, embodiments, and features are also included.

Abstract: A UE may improve power performance by adjusting measurement reports based on uplink power. The UE factors in the uplink transmit power into the downlink radio signal strength measurement results that are reported to a network. When the UE is transmitting higher than normal uplink power, the UE can adjust the measurement results and report an artificially lower measurement result to the network, to account for the uplink transmit power. The UE may trigger a handover based at least in part on the adjusted measurement report.
