Abstract: A base station determines a window of time for arrival of uplink signals, wherein the window of time includes a start based on a first expected time of arrival for a first uplink signal from a first UE and an end based on a second expected time of arrival for a second uplink signal from a second UE. The base station detection detects a false base station, such as a L1 man-in-the-middle false base station, based on an uplink signal being received outside of the determined window of time for the arrival of uplink signals.

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: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may transmit capability information including an indication of a discontinuous monitoring delay period. The UE may receive a message including an indication to adjust monitoring of a physical downlink control channel (PDCCH), and monitor for the PDCCH during the discontinuous monitoring delay period. The UE may adjust monitoring for the PDCCH following the discontinuous monitoring delay period during a temporal period based on the received indication to adjust monitoring of the PDCCH. In some examples, at least one of physical downlink shared channel (PDSCH) reception, downlink reference signal monitoring, uplink reference signal transmissions, and channel reporting is enabled during the temporal period while monitoring of the PDCCH is adjusted.

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: Techniques are described for wireless communication. One method includes receiving a first transmission according to a first radio access technology (RAT); determining a transmitter of the wireless communication device is tuned to a second RAT during a default feedback transmission time for the first transmission; and transmitting feedback for the first transmission at a delayed feedback transmission time for the first transmission. The delayed feedback transmission time is based at least in part on a timing for tuning the transmitter from the second RAT to the first RAT. Another method includes transmitting a first transmission, in which the first transmission is associated with a default feedback transmission time for the first transmission; and receiving feedback for the first transmission at a delayed feedback transmission time for the first transmission.

Abstract: The described aspects include a user equipment (UE) apparatus and corresponding method of performing a High-Speed Uplink Packet Access (HSUPA) transmission. The aspects include determining availability of information for transmission while the UE is in a Cell_FACH state and an idle mode. Further, aspects include generating a message including a scheduling information (SI) indicator during a collision resolution phase of an uplink procedure when SI data is allowed to be transmitted during the collision resolution phase, wherein the SI indicator identifies whether the SI data is included in a Medium Access Control-i (MAC-i) Packet Data Unit (PDU). Additionally, the aspects include transmitting the message, destined for a network component, during the collision resolution phase. The described aspects also include a corresponding network component and method for receiving the message and unambiguously determining presence of SI data in the MAC-i PDU.

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).
