  • Publication number: 20220015183
    Abstract: This disclosure relates to performing implicit radio resource control state transitions in a cellular communication system. A wireless device may establish a radio resource control (RRC) connection with a cellular base station. A data inactivity timer length and a target RRC state for implicit RRC transitions may be determined. A data inactivity timer having the determined data inactivity timer length may be initiated. It may be determined that the data inactivity timer has expired. The wireless device may transition to the target RRC state based at least in part on determining that the data inactivity timer has expired.

  • Patent number: 11218924
    Abstract: Techniques are disclosed relating to handover between cellular base stations. In some embodiments that use dual-connectivity handover, disclosed techniques may facilitate synchronization of a security configuration switch. In some embodiments, the base station and/or mobile device determine activation sequence numbers for the security configuration switch (e.g., by estimating when a path switch will occur). In some embodiments, the security configuration switch is implicitly detected based in deciphering failure. In some embodiments, the security configuration switch is explicitly signaled and is checked based on deciphering failure. In some embodiments that use make before break handover techniques, a source base station may be retained after the path switch.

    Abstract: Provided are a positioning reference signal (PRS) transmission method and apparatus, and a storage medium. A PRS sending end presets PRS blocks having the same number as the number of shaped beams, a corresponding PRS sequence in each PRS block by using a preset sequence generation rule, and each PRS block containing the corresponding PRS sequence is sent according to a preset sending order of the PRS blocks in a polling manner through a shaped beam corresponding to the each PRS block. A PRS receiving end acquires a first PRS block sent by the PRS sending end; and when the first PRS block contains a block index, a sending index of a shaped beam corresponding to the first PRS block corresponding to the block index is determined according to preset correspondence; or when the first PRS block contains no block index, a sending index of a shaped beam corresponding to the first PRS block is determined according to a preset calculation rule.
