In some aspects, a method of communicating in a wireless network includes transmitting, at an access point, a full beacon at a first multiple of a beacon interval. The method further includes transmitting a compressed beacon at each beacon interval that is not the first multiple of the beacon interval. Another method of communicating in a wireless network includes receiving, at a wireless device, a full beacon at a first multiple of a beacon interval. The method further includes receiving a compressed beacon at a beacon interval that is not the first multiple of the beacon interval.

Abstract: A core network receives data from at least one of an AF, a DN, or a UE. A UPF having small data capability processes the data for transport with a low overhead and without initiating a bearer set up protocol. The data may be transported between the UE and the UPF as an RRC payload over a NAS protocol. The data may be received from an AF or DN external to the core network and may be processed to transport the data to the UE based as an RRC payload. The data may be received as uplink data from a UE, e.g., in an RRC payload. The UPF may process the RRC payload to obtain the data and may transport the data to the AF or DN. The UPF may perform IP header compression, data encryption, and/or buffering of data for a UE in an idle mode.

The method includes receiving, at an apparatus, at least one of: an offset parameter indicating an offset, with respect to a default time period, during which the apparatus should be in an active mode for transmitting and/or receiving data, and an interval parameter indicating a multiple of time periods, wherein the apparatus should be in the active mode for transmitting and/or receiving data during each time period. The method further includes determining at least one wakeup time period to be in the active mode based on the offset parameter or the interval parameter. The method further includes transmitting and/or receiving data during the at least one wakeup time period.

Abstract: A method, a user equipment, a 5G core network device, an apparatus, and a computer program product for wireless communication are provided. Battery life and network efficiency of the user equipment are improved through the usage of a polled-mode power saving technique, wherein the user equipment periodically awakens to poll the 5G core network device regarding whether a communication is available for the user equipment. If the communication is available, the user equipment receives the communication. If the communication is delayed, the user equipment performs discontinuous reception to save power until the communication is available. If the communication is unavailable, the user equipment resumes a sleep mode.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for generating wake-up radio (WUR) frames formats and implementing WUR communications between transmitting and receiving wireless devices. A transmitting wireless device may identify one or more intended receiving wireless devices for which to send a WUR frame. The transmitting wireless device may generate the WUR frame, where the WUR frame has a first portion that includes a first field. The first field may indicate whether the WUR frame is a fixed length frame or a variable length frame. The transmitting wireless device may also determine a frame check sequence (FCS) type for use with a WUR frame for transmission. The FCS portion may be capable of being one of a plurality of FCS types. The transmitting wireless device may transmit the WUR frame to the one or more intended receiving wireless devices.
