Systems, devices and methods are provided for power-efficient wireless communications between electronic devices. In particular, the embodiments disclosed herein can reduce battery consumption in a transmitting electronic device and enhance data integrity of data received by a receiving electronic device. According to the embodiments, a first electronic device transmits advertising packets according to a wireless communications protocol, wherein the advertising packets include a first payload data. In response to receiving the advertising packets, a second electronic device can transmit a scan request to the first electronic device which, in turn, terminates the transmission of advertising packets.

A method and a device for receiving transmitting data in in a wireless local area network are provided. The device receives a physical layer protocol data unit (PPDU) from a station over a transmission bandwidth and determines whether the station is a member of a basic service set (BSS) managed by the device based on the PPDU. When the PPDU is a multi-user (MU)-PPDU, the AP determines that the station is not a member of the BSS managed by the AP. Such MU-PPDU includes a first signal field and a second signal field, the first signal field having bandwidth information indicating the transmission bandwidth, the second signal field having user-specific information with allocation for orthogonal frequency division multiple access (OFDMA) transmission.

An electronic device may advertise a first BSSID and a second BSSID having a common SSID, separate wireless connection interfaces, and different capabilities, where the first BSSID may support a first IEEE 802.11 standard, and the second BSSID may support one or more previous IEEE 802.11 standards, but may not support the first IEEE 802.11 standard. Then, the electronic device may receive a probe request associated with a second electronic device. Moreover, the electronic device may determine whether the second electronic device supports the first IEEE 802.11 standard based at least in part on one or more fields in the probe request. Next, the electronic device may selectively provide a probe response to the second electronic device with one of the first BSSID and the second BSSID based at least in part on the determination.

Disclosed are a method and an apparatus for performing uplink/downlink transmission and reception on the basis of a beam linkage state in a wireless communication system. A method for performing uplink transmission or downlink reception by a terminal in a wireless communication system according to an embodiment of the present disclosure may comprise the steps of: receiving configuration information for a first beam linkage state (BLS) for a first resource and a second BLS for a second resource from a base station, wherein each of the first and second BLSs includes information on a mapping relationship between reference transmission and reception and one or more target transmissions and receptions; receiving, from the base station, reference spatial parameter indication information for the reference transmission and reception with regard to the first resource; and performing the uplink transmission or the downlink reception through the second resource, on the basis of a target spatial parameter for specific target transmission and reception among the one or more target transmissions and receptions, wherein the target spatial parameter may be determined on the basis of the reference spatial parameter.

A terminal includes a receiver configured to receive first system information from a base station; and a controller configured to acquire, from the first system information, a first list, a second list, and a third list for scheduling second system information other than the first system information, and to determine a start position of a window for acquiring the second system information, based on the first list, the second list, and the third list, wherein the receiver receives the second system information from the base station in the window.

Disclosed are a method and apparatus for transmitting system parameters of a soft access device, a device and a medium. A method for acquiring system parameters of a soft access device includes: receiving a broadcast message sent by the soft access device on a main link, a reduced neighbor report information element in the broadcast message including a multi-link device identifier, an identifier of a non-main link and a system parameter change count; sending a first message for requesting system parameters on the non-main link to the soft access device on the main link in a case that the received broadcast message indicates that a value of a system parameter change count corresponding to the non-main link is different from that of a system parameter change count received last time; and receiving a second message in response to the first message and sent by the soft access device on the main link.
