摘要： Methods, apparatuses, and computer programs are presented for operation during a network discovery process of a scanning device attempting to detect presence of wireless networks. During the network discovery process, the scanning device itself may transmit scanning messages by using duplicate transmission in which multiple scanning messages are transmitted simultaneously on different channels. According to another aspect, a wireless apparatus of a wireless network may transmit scanning messages by using the duplicate transmission to facilitate the detection of the wireless network by the scanning device.

摘要： There is provided a method, comprising: transmitting, by a user equipment (100), at least one uplink data frame (400) to a first access point (102) of a wireless local area network, wherein the first uplink data frame of the transmitted at least one uplink data frame initiates a transmission opportunity (416); and transmitting at least one up-link data frame (404) to a second access point (104) of a wireless local area network within the same transmission opportunity (416).

摘要： A method, apparatus, and computer program for carrying out channel sounding are provided. Said method comprises: causing, by an apparatus, transmission of a request for space-time channel sounding to at least one unassociated access node; receiving, in the apparatus as a multi-antenna transmission and in response to said request, at least one message comprising space-time sounding information from at least one unassociated access node; determining, by the apparatus, at least one parameter describing space-time channel quality from the received space-time sounding information; and causing, by the apparatus, transmission of the at least one determined parameter to an associated access node or causing selection of an unassociated access node for further communication based at least partly on the determined at least one parameter.
