    Abstract: The present disclosure relates to techniques for wireless communication between electronic devices in a wireless network, such as a mesh wireless network. For example, a first electronic device may include processing circuitry that is configured to cause a transceiver of the first electronic device to transmit to a second electronic device in a wireless network an indication of time slots. The processing circuitry may cause at least a portion of the transceiver to enter a low power state during one or more times outside the time slots and cause the transceiver to exit the low power state to transmit or receive wireless signals during the time slots.

    Abstract: This disclosure relates to techniques for efficient sparse network resource usage and connection release procedures. According to some embodiments, a wireless device may utilize techniques for efficiently releasing a radio resource control (RRC) connection, including techniques that avoid or reduce the occurrence of random access procedures when out-of-sync with the network when the RRC connection is being released. In some embodiments, a wireless device may utilize techniques for efficiently sparsely using network uplink resources, including techniques that avoid or reduce the occurrence of random access procedures to regain timing alignment to perform uplink communication when out-of-sync with the network.

    Abstract: This disclosure relates to techniques for securely performing connection release and network redirection in a wireless communication system. A wireless device may establish a radio resource control (RRC) connection with a first cell. The wireless device may receive a RRC connection release message from the first cell. The RRC connection release message may include an indication to redirect the wireless device to a second cell. The RRC connection with the first cell may be released. It may be determined whether security has been established with the first cell when the indication to redirect the wireless device to the second cell is received. A new serving cell may be selected based at least in part on whether security has been established with the first cell when the indication to redirect the wireless device to the second cell is received.

    Abstract: Apparatuses, systems, and methods for user equipment (UE) devices to perform a postponement of a data service request are described. A UE may detect a data service request failure during cell reselection and postpone a resend of the data service request based on a status of the cell reselection. The status may be an indication that the UE is attempting to camp on a cell or that the UE is monitoring one or more metrics associated with cell reselection. To postpone the data service request, the UE may postpone the data service request for a specified period of time or until the cell reselection is complete. The status may be monitored on a first layer of a protocol stack and the data service request may generated by a second layer of the protocol stack. The postponement may be for a fixed or variable time period.

    Abstract: Mechanisms enabling link-budget-limited (LBL) devices to more effectively perform random access may include: (1) broadcasting a Physical Random Access Channel (PRACH) configuration index (PCI) reserved for LBL devices; (2) configuring LBL devices to use a PCI that is offset from the conventional PCI of current cell; (3) configuring LBL devices to transmit PRACH messages using an alternative set of subframes, different from conventionally-defined subframe set; (4) configuring LBL devices to transmit PRACH messages on odd frames when the conventional PRACH configuration specifies even frames; (5) configuring LBL devices to generate and use extra PRACH preambles that are not used by non-LBL devices; (6) configuring LBL devices to use group B preambles while non-LBL devices are configured to use group A preambles; and (7) boosting power of a random access response message after an Nth random access failure with preamble conforming to an LBL-reserved pattern of preambles.

    Abstract translation: 使链路限制（LBL）设备更有效地执行随机接入的机制可以包括：（1）广播为LBL设备预留的物理随机接入信道（PRACH）配置索引（PCI）; （2）将LBL设备配置为使用与当前单元的常规PCI相抵消的PCI; （3）使用不同于传统定义的子帧组的替代的一组子帧来配置LBL设备来发送PRACH消息; （4）当常规PRACH配置指定偶数帧时，配置LBL设备在奇数帧上发送PRACH消息; （5）配置LBL设备以生成和使用未被非LBL设备使用的额外的PRACH前导码; （6）将LBL设备配置为使用B组前导码，而将非LBL设备配置为使用A组前导码; 以及（7）在符合LBL预留的前导码模式的前导码的第N个随机接入故障之后提升随机接入响应消息的功率。
