摘要:
A system and method for a hierarchical network operating mode in an ad hoc wireless communications network. In one embodiment, a communications node includes a controller and a transceiver. The controller is configured to create a bandwidth allocation request for other communications nodes in an ad hoc wireless communications network. The transceiver is configured to receive request grants from the other communications nodes granting the bandwidth allocations in accordance with the bandwidth allocation request, thereby establishing a hierarchical network operating mode in at least a portion of the ad hoc wireless communications network.

A flexible transmission resource reservation scheme and data transmission scheme is provided for a wireless network. A source node transmits a data transfer reservation request for a transmission resource to at least one neighboring node including at least one target node of the wireless network. The source node may have data to be transmitted or may anticipate data reception from at least one of the target nodes. Then, the source node receives from the at least one neighboring node an acknowledgment to reserve the requested transmission resource for data transfer between the source node and the at least one target node. Thereafter, data is transferred between the source node and the at least one target node within the reserved transmission resource.
摘要:
An approach is provided for resource allocation within a network. A request is generated for resource allocation from a neighboring node within a network. The request is inserted in a beaconing subframe of a transmission frame. The transmission frame includes a reservation subframe that provides acknowledgement signaling relating to a grant of the resource allocation.

The present document provides a method, apparatus, and computer program for determining, in a communication device of a first basic service set comprising a group of communication devices of a wireless telecommunication network, a primary channel of a second basic service set different from said first basic service set. Thereafter, the communication device causes transmission of channel identification information defining a location of at least one channel of the first basic service set from the communication device to the second basic service set on the determined primary channel of the second basic service set.

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:
An apparatus, method and system to set a control channel configuration in a response to an indication of interference in a communication system. In one embodiment, an apparatus includes a processor 520 and memory 550 including computer program code. The memory 550 and the computer program code are configured to, with the processor 520, cause the apparatus to detect interference for the apparatus operable on a communication system from another communication system, and provide an indication of the interference to a base station. The memory 550 and the computer program code are further configured to, with the processor 520, cause the apparatus to receive an indication of a relocation of at least a portion of a control channel to a protected area in response to a signal from the base station.
摘要:
Service discovery for services on a wireless network is presented. It is determined (e.g., from a received Layer 2 message) that an offering apparatus h made a service available to entities joined to a wireless network. Then in a message, that is available to entities not joined to the network, is placed information about the services and also at least one of location information about the offering apparatus and link metric information about a network path to the offering apparatus. A discovering apparatus reads one or more transmitted messages (from different apparatuses in the same network in different networks), sees the service it wants is available through both, compares the different locations and/or the different link metrics, and based on the comparing chooses which network to join, or with which apparatus on the single network to create a peer link.

Various embodiments are disclosed relating to techniques for RTS/CTS usage in a wireless network. According to an example embodiment, a network performance may be measured within a wireless network. A variety of parameters may be measured at a wireless node to determine a network performance. In addition, it may be determined whether the network performance has reached a degraded performance threshold. A frame is transmitted via the wireless network. If the network performance has reached the degraded performance threshold, the frame may be transmitted using a Request-to-Send/Clear-to-Send (RTS/CTS) protection. In another example embodiment, a frame may be transmitted using RTS/CTS protection if an estimated transmission time for the frame exceeds a transmission time threshold.
摘要:
An apparatus (STA) receives from a first node (AP1) at least one channel access related parameter and a first congestion indication; and receives from a second node (AP2) a second congestion indication. The apparatus determines a combined congestion indication which is based at least on the first congestion indication and the second congestion indication; and determines a first channel access parameter for a channel between the apparatus and the first node based at least partly on the at least one channel access related parameter and the combined congestion indication. In specific embodiments, the channel access related parameters may be an initial EDCA parameter and a degradation factor.
