Many aspects pertaining to various apparatuses, methods, and computer-readable medium are described herein. Some aspects pertain to wireless communication between various apparatuses, which may include one or more access points (APs) and/or one or more stations (STAs). The one or more APs and/or one or more STAs may have one or more radios. Some aspects pertain to various features related to such one or more radios. Some aspects pertain to certain technologies related to uplink (UL) communication(s) and/or downlink (DL) communication(s). The written description and appended drawings provide detailed descriptions regarding these and many other aspects.

To make effective the usage of wireless networks, and in particular IEEE 802.11 networks, it is described a method of coordinating communications comprising a group of access points, APs, sharing resources during a transmission opportunity, TXOP, gained by a first AP of the group, the first AP is configured to allocate resources to second APs of the group within the TXOP, wherein the group is formed based on the capabilities of the APs to share and/or use shared resources, and/or on the enablement status of the APs of their function to share and/or use shared resources.

A method and apparatus may be used in wireless communications. The apparatus may be an access point (AP), and may transmit a power save frame. The power save frame may include one or more Uplink (UL) Transmission Times (ULT)s. The apparatus may determine that a station (STA) did not transmit during its respective ULT. The AP may transmit another power save frame. The other power save frame may include a modified ULT. The modified ULT may be for a STA that did not transmit during its respective ULT. The other power save frame may include an unmodified ULT. The unmodified ULT may be for a STA that did not transmit.

Disclosed is a wireless networking method having low power consumption and high interference resistance. Basic communication units comprise a base station and a node. The base station takes charge of network construction and management, and the node and the base station communicate with each other by using adaptive frequency hopping and time division multiple access technologies; a plurality of time slots are obtained by division for communication, the time slots are divided into transaction time slots and data time slots, and the transaction time slots take charge of broadcast information transmission, synchronous information transmission, and network access of the node; and the data time slots take charge of data interaction between the base station and the node. The method can achieve available low-power-consumption, large-capacity, high-reliability, and low-latency underlying wireless communication in a complex and congested wireless environment, and can operate in a 2.4 GHz frequency band to achieve worldwide availability.

An example device comprising: a processor to determine that a client device is located in an overlapping area between the first network device and a second network device, to synchronize a first clock of the first network device with a second clock of the second network device, to negotiate, with the second network device, a overlapping access window, an overlapping forbidden window, and a non-overlapping access window for the first network device and the second network device in beacon intervals, to allocate the overlapping access window, the overlapping forbidden window, and the non-overlapping access window by the first network device, to store the allocated overlapping access window, the allocated overlapping forbidden window, and the allocated non-overlapping access window as channel scheduling rules for spatial reuse, and to control frame transmission of the network device based on the channel scheduling rules.

User equipment (UE)—initiated accesses within a cellular network are optimized to account for cell size and to reduce signaling overhead. A fixed set of preamble parameter configurations for use across a complete range of cell sizes within the cellular network is established and stored within each UE. A UE located in a given cell receives a configuration number transmitted from a nodeB serving the cell, the configuration number being indicative of a size of the cell. The UE selects a preamble parameter configuration from the fixed set of preamble parameter configurations in response to the received configuration number and then transmits a preamble from the UE to the nodeB using the preamble parameter configuration indicated by the configuration number.
