Abstract: In wireless communication networks using carrier aggregation including a secondary component carrier in unlicensed spectrum, a user equipment (UE) may monitor a downlink radio link quality of secondary cells for an event indicating failure of a communication link in the unlicensed spectrum with a secondary cell. The UE detects one or more failure events based on the downlink radio link quality. When a designated set of failure events is detected, the UE declares a failure state on the secondary cell. In response to the failure state, the UE may adjust operations related to the secondary component carrier in the unlicensed spectrum in order to save power and resources.

Abstract: Wireless communications systems and methods related to improve control reporting latency are provided. A wireless communication device receives, from a first link in a first time interval, first control information associated with a second link and the first time interval. The wireless communication device transmits, via the second link in the first time interval, a control report associated with the second link based on a report configuration that is independent from the first control information. The report configuration is associated with a waveform type. The wireless communication device receives, from the first link in a second time interval following the first time interval, second control information that is dependent on the control report. The report configuration includes a power headroom (PHR) report configuration. The PHR report configuration includes a reference PHR report configuration. The PHR report configuration includes a delayed PHR report configuration.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications. In some aspects, a wireless communication device may determine that the wireless communication device is configured to use a primary component carrier (PCC), a first secondary component carrier (SCC), and a second SCC for carrier aggregation. A primary cell may be associated with the PCC, a first secondary cell may be associated with the first SCC, and a second secondary cell may be associated with the second SCC. The first secondary cell may provide control information for the second secondary cell. The wireless communication device may monitor at least one of the first SCC or the second SCC. The wireless communication device may perform an action associated with the second secondary cell based, at least in part, on monitoring the at least one the first SCC or the second SCC.

Abstract: Techniques are described for wireless communication at a wireless communication device. A determination may be made regarding the number of receive chains, of a plurality of receive chains, to enable for a channel. Power to the receive chains may be regulated based on the determined number of enabled receive chains. The determination may be based on a transmission scheduling rate for the wireless communication device and a rank for the channel. In some examples, the determination may further be based on a channel quality of the channel and/or a type of traffic scheduled for the channel.

Abstract: Methods, systems, and devices are described for signaling device-to-device (D2D) capability information. A user equipment (UE) may determine a frequency band list of frequency bands supported for D2D proximity service communications. Based on the frequency band list, the UE may determine a proximity service record for a frequency band combination parameter, the frequency band combination parameter associated with non-D2D communications. The proximity service record may include a reduced capabilities record for the frequency band combination parameter that indicates reduced capabilities for non-D2D communications when D2D proximity service communications are active.

Abstract: A user equipment (UE) may have data in a buffer for uplink (UL) transmission. The UE may transmit a buffer status report (BSR) indicating the amount of data. The BSR may fail or a base station may not grant sufficient resources for transmission of the data. A BSR failure condition may be based on a radio link control (RLC) operating mode of the data. For example, the data may be an acknowledgement (ACK) for an acknowledged mode (AM) DL transmission. In this case, the UE may initiate a BSR retransmission (Retx-BSR) timer and determine whether any duplicate transmissions have been received. The data may also be associated with an unacknowledged mode (UM), and the BSR failure condition may include waiting for a time interval that is less than the Retx-BSR time interval. When the BSR failure condition is satisfied, the UE may transmit a scheduling request to the base station.

Abstract: Techniques are provided for controlling downlink data transfer during carrier aggregation. For example, a method may control a secondary component carrier downlink (DL) in a wireless communication network using carrier aggregation. The method may include detecting, by a mobile entity, an event indicating a resource constraint at the mobile entity related to a data transmission from a base station to the mobile entity on a secondary component carrier of a carrier aggregation enabled connection. The method may include, in response to detecting the event, controlling the data transmission by signaling a status of the secondary component carrier DL to the base station.

Abstract: Disclosed are methods and apparatus for improving the performance of a user equipment handover during a data call. In one aspect, a source base station determines to handover user equipment (UE) to a target base station. The source base station first determines whether the UE is in a data call prior to the handover. The source base station then modifies one or more of connected mode discontinuous reception (CDRX) and semi-persistent scheduling (SPS) parameters with the UE based on determining to handover the UE and determining that the UE is in the data call.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in which a probability of occurrence of an event expected to occur within a period of time is determined, where the event comprises one or more of a tune-away event and a suspension event. One or more transmission control protocol parameters are manipulated before the occurrence of the event when the probability of occurrence exceeds a threshold to increase a retransmission time out parameter value, or to maintain a desirable congestion window size. The transmission control protocol parameters may be manipulated by delaying, duplicating or dropping acknowledgements and/or by selectively dropping received packets before, during, or after the event.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may wake up from a sleep mode of a discontinuous reception (DRX) cycle based on receipt of uplink data. The UE may determine if an elapsed time between a prior receipt of one or more reference signals and an uplink transmission to the base station after waking up from the sleep mode is less than a threshold time value. If the elapsed time is less than the threshold time value, the UE may transmit an uplink transmission associated with the received uplink data prior to receiving one or more reference signals that may be used to update transmission parameters for uplink transmissions. If the elapsed time is at or above the threshold value, the UE may wait to receive the one or more reference signals and update the transmission parameters prior to the uplink transmission.
