System and method for collection, control and wireless transmission of environmental and other data. Nodes may wirelessly connect to other nodes to relay node specific information, collected sensor data or commands to and from other nodes and gateway nodes linked to a central database. Nodes in gateway mode may be capable of aggregating and relaying commands and data between other nodes and a centralized database. Nodes may bypass other nodes and/or gateway nodes and communicate directly with the central database via satellite or cellular link. Nodes may be self-contained devices, inclusive of a wind or solar power source and a battery, eliminating the need for an external power source. Nodes may be configured independently or as a system to monitor and control various types of equipment including utility lines or water systems or used to collect environmental data. Nodes may communicate on different channels/frequencies based on systematic or pseudo-random changes.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a wakeup signal (WUS) associated with a discontinuous reception (DRX) ON duration; determine that a grant was not detected in the DRX ON duration; and perform an action based at least in part on whether the WUS is specific to the UE or is associated with a group of UEs. Numerous other aspects are provided.

Embodiments of the present application are related to a method and apparatus for wake up signal (WUS) detection. An embodiment of the present application provides a method. The method may include: receiving WUS configuration information including user equipment (UE) grouping information and WUS alternating information; determining an initial WUS sequence based on the UE grouping information; and monitoring a WUS sequence based on the initial WUS sequence and the WUS alternating information.

Networked sleep mode management is provided by measuring network conditions for a first Access Point (AP) serving a plurality of Client Devices (CDs) configured to operate in one of a sleep mode and an active mode; in response to detecting, based on the measured network conditions, an amount of network usage devoted to transitioning members of the plurality of CDs from the sleep mode to the active mode satisfies a threshold: identifying a first subset of CDs from the plurality of CDs that are deprioritized for access to the sleep mode; receiving a sleep request from a given CD that is a member of the first subset of CDs; and denying the sleep request to force the given CD to maintain the active mode for at least a predefined amount of time.

The present disclosure provides detailed specifications related to user equipment (UE) aggregation. As an example, a virtual UE (VUE) configuration, also referred to as a configuration for UE aggregation, that can be used by multiple UEs participating in UE aggregation may be communicated in a wireless communication network. The configuration may indicate, for example, that the UEs are to participate in UE aggregation, and indicate a first UE for splitting or combining data. In some embodiments the configuration may indicate protocol stacks for the multiple UEs to participate in UE aggregation, and an anchor point. The anchor point is associated with a layer in the protocol stack of a first UE of the multiple UEs, and implements data splitting and/or aggregation. As an alternative to the specific example of an anchor point, a configuration may indicate a function for splitting or aggregating data.

Embodiments include methods for an access point to schedule wireless communication devices. Such methods include performing link adaptation by assigning respective modulation and coding schemes (MCS) for the wireless communication devices. Each assigned MCS is associated with a corresponding power back-off. Such methods include scheduling the wireless communication devices on transmission resources based on assignment of the wireless communications devices into two or more groups. Each group is scheduled on different transmission resources than used to schedule other groups. First wireless communication devices assigned a first MCS and a first power back-off are assigned to a first group. Second wireless communications devices assigned a second MCS and a second power back-off, and that meet a grouping criterion associated with the first power back-off, are assigned to the first group until a maximum size for the first group is reached. Other embodiments include access points configured to perform such methods.

Methods, systems, and devices for wireless communications are described. According to one or more aspects, a user equipment (UE) may receive a configuration message from a base station. The configuration message may configure the UE based on one or more identifiers associated with a group of UEs. The UE may determine at least one identifier based on receiving the configuration message, and may monitor a signal based on the at least one identifier. In some cases, the signal may indicate whether the UE should skip an upcoming duration associated with a discontinuous reception. The UE may then communicate with the base station, based on monitoring the signal.

Methods, apparatus, and systems for reducing Peak Average Power Ratio (PAPR) in signal transmissions are described. In one example aspect, a wireless communication method includes determining, for an input sequence, an output sequence. The output sequence corresponds to an output of a convolutional modulation between a set of coefficients and an intermediate sequence. The intermediate sequence is generated by inserting N zero coefficients between coefficients of the input sequence. The number of non-zero coefficients in the set of coefficients is based on N, N being a positive integer. Values of the non-zero coefficients correspond to values between 0 to π/2 to reduce a peak to average power ratio of the output sequence. The method also includes generating a waveform using the output sequence.

A method performed by a wireless device operating in a wireless network, wherein the wireless device includes a main radio and a wake-up receiver. The method includes detecting, by a first component of the wake-up receiver, a wake-up receiver preamble in a wireless transmission received by the wireless device and waking up a second component of the wake-up receiver in response to detecting the wake-up receiver preamble.

A method for receiving a backoff value at a wireless station is presented. A traffic indication map is received at the station, wherein a backoff number is implicitly assigned to the station based on a position of the station within the traffic indication map. The backoff value is determined by multiplying the backoff number by a predetermined time value.
