Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may receive during an active duration, an indication of an opportunity to request uplink (UL) transmission. The wireless device may identify an opportunity to request UL transmission based at least in part on the indication. In some cases, the active duration may be a discontinuous transmission (DTX) configuration. The wireless device may then transmit on the UL resources during the opportunity to request UL transmission.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may receive a downlink (DL) reception indication during an active duration of a discontinuous reception (DRX) configuration. The DL reception indication may indicate the presence of a reception opportunity following an inactivity interval, as well as the length of the inactivity interval. The wireless device may refrain from DL monitoring during the inactivity interval. In some cases, the wireless device may enter a sleep mode during the inactivity interval and wake up to receive a subsequent transmission during the reception opportunity. In some examples, the wireless device may use the inactivity interval to communicate using a different radio access technology (RAT).

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station in a wireless communications system. The base station may transmit signaling to the UE over a broadcast channel. The base station may transmit control signaling to the UE that indicates a broadcast root key. The UE may identify the broadcast root key for a wireless network corresponding to the base station. The base station may transmit an encrypted broadcast transmission. The UE may receive the encrypted broadcast transmission from the base station, and the UE may decrypt the encrypted broadcast transmission to obtain broadcast information based on a cell-specific key derived from the broadcast root key.

Abstract: Systems, methods, and apparatuses for improved traffic management in wireless communications are disclosed. Aspects of the present disclosure provide real-time assessments to a network by leveraging measurement reports from user equipment (UE). In some aspects, the network utilizes channel quality indicator (CQI) information from each of a serving cell and a neighboring cell to identify UE capabilities and expected UE performance prior to either offloading or rerouting traffic to the UE. Accordingly, based on the received CQI information and a greater understanding of the anticipated UE performance, the radio network controller (RNC) may be better equipped to determine whether to offload and/or reroute the traffic scheduled for transmission to the UE via the neighboring cell or the serving cell.

Abstract: Techniques are described for wireless communication. A base station may indicate to a UE, in a pre-wakeup period, whether the base station will transmit a grant to the UE. The pre-wakeup period may occur at the beginning of a DRX cycle. The base station may transmit an indication of a grant to the UE, and the base station may indicate a time period during which the UE may wake up to receive the grant. The indication may include scheduling information for the grant. The UE may select a DRX mode based on a configuration received from the base station, a traffic pattern, or scheduling history. The UE may monitor for the grant, and receive the grant. In other examples, the UE or the base station may identify that the grant was not received, and may reset a DRX cycle based on the identification.

Abstract: Systems and method of embodiments herein operate to conserve battery power of user equipment (UE). Embodiments determine whether waking up a UE receiver would be beneficial and based on the determination, the UE either wakes up the receiver or returns to sleep. Embodiments determine whether to wake up the receiver by performing pre-wake up (PWU) operation which either wakes up the receiver in a low power mode or wakes up the UE's wake up receiver. It may be determined whether a wake up (WU) signal is received during a PWU stage. If a WU signal is received during the PWU stage the UE may perform a full wake up of the receiver. If a WU signal is not received the UE may return to idle mode. In embodiments, WU (Wake Up) DRX cycles are supplemented with a Full DRX (Discontinuous Reception) cycle.

Abstract: Techniques are described for wireless communication. One method includes determining a portion of a transmission time interval (TTI) is available for a transmission that is shorter than a duration of the TTI; selecting a transmission format for transmitting the transmission to a receiving device during the portion of the TTI; and indicating a timing of the transmission to the receiving device. Another method includes determining a portion of a TTI is available for a transmission that is shorter than a duration of the TTI; selecting a transmission format from a plurality of transmission formats for transmitting the transmission to a receiving device during the portion of the TTI; and transmitting the transmission to the receiving device.

Abstract: Aspects of the present disclosure provide various techniques for requesting a system information block (SIB) and providing a SIB response for a user equipment (UE) in a UE-centric wireless communication network. In some aspects of the disclosure, the network may transmit the SIB to the UEs in a broadcast mode or in an on-demand mode.
