摘要:
Methods, apparatuses, and a computer program are presented for determining a reservation period for data transmission in a wireless communication network. The duration of the reservation period is determined on the basis of RTS/CTS handshake between a transmitter and a receiver apparatus.
摘要:
A wireless device may perform one or more omnidirectional scans for network wireless devices. Based at least in part on results of those omnidirectional scans, the scanning wireless device may determine that one or more directional scans should be performed. The scanning wireless device may then select one or more scan directions and perform a directional scan in each of those scan directions.

This document discloses a solution for transmitting scanning response messages in an orderly manner in a wireless network. An access node determines a transmission order for a plurality of access nodes responding to a scanning request message provided by a scanning/requesting device. Then, the access node determines its own transmission turn within the transmission order and transmits a scanning response message with reduced channel contention. Another aspect relates to the scanning device arranged to receive the scanning response messages where the scanning device monitors the transmission order of the scanning response messages.
摘要:
There is provided a method comprising: causing a station capable of communication in a wireless network to acquire knowledge of a medium usage indicator with respect to at least one channel applicable for transmission of a scanning request; and determining a transmission time for a next scanning request at least partly based on the medium usage indicator.
摘要:
A method, apparatus, and computer program for monitoring messages transmitted in a wireless network are disclosed. On the basis of the monitoring, it is determined that a transmission rate of messages is not sufficient upon detecting no message within a minimum transmission time interval and, upon determining that the transmission rate of messages is not sufficient, an access point of the wireless network is caused to transmit a scanning message.
摘要:
Method, apparatus, and computer program product embodiments of the invention are disclosed to improve the discovery of wireless networks. In example embodiments of the invention, a method comprises: transmitting a wireless message including a list of one or more wireless devices, from which a response is not desired; and receiving zero or more responses from one or more other wireless devices that are not on the list.
摘要:
Methods and apparatuses for indicating status of radio resources in a wireless network are provided. A requesting device transmits a resource request on a first radio channel to a responding device. The resource request includes a request to reserve the first radio channel between the requesting device and the responding device. The responding device transmits a resource response on the first radio channel in response to the resource request. The resource response comprises status information indicative of status of at least one second radio channel not requested to be reserved by the requesting device.

Method, apparatus, and computer program product embodiments of the invention are disclosed to improve the discovery of wireless networks. In example embodiments of the invention, a method comprises: transmitting, by an apparatus, one or more wireless discovery request messages to discover a wireless network matching one or more predetermined characteristics; receiving by an apparatus, from one or more wireless devices, zero or more wireless responses to the one or more wireless discovery request messages, and transmitting by the apparatus, a wireless message including an indication that the apparatus will not listen to further wireless responses.
摘要:
A method, apparatus, and computer program for controlling transmission power of a radio apparatus are provided. The method includes: determining, in a radio apparatus configured to support a cellular radio access technology in communication with a cellular counterpart apparatus and a short range radio access technology in communication with a short range counterpart apparatus, a maximum total transmit power of the radio apparatus; causing the radio apparatus to use a first transmit power level in transmission to the cellular counterpart apparatus; determining a remaining transmission power margin by computing a difference between the maximum total transmit power and the first transmit power level; and causing the radio apparatus to autonomously limit a second transmit power level to fall within the remaining transmission power margin and to use the second transmit power level in transmission to the short range counterpart apparatus.
