Delay constrained use of automatic repeat request for multi-hop communication systems

Номер: US0008014336B2
Принадлежит: Nokia Corporation, NOKIA CORP, NOKIA CORPORATION

Minimization of delay due to automatic repeat requests in a multi-hop communication system can be accomplished to optimize the performance of delay-constrained applications such as voice over internet protocol (VoIP). The protocol described with relation to such embodiments can reduce the possible retransmissions to the first hop (the hop connecting a mobile node to a relay node). Thus, certain embodiments of the present invention can protect the most error-prone link while reducing the overall delay experienced by the user.

Systems and techniques for management of wireless network transmission. A high efficiency wireless network that can operate using a contention free period defines an interframe space that is shorter than the interframe space used in legacy networks, so that a legacy network will be unable to contend for the medium if the high efficiency wireless network transmits during the contention free period. Before the contention free period begins, a high efficiency network element examines a transmission medium, and if an ongoing transmission extends into the contention free period, transmission by the high efficiency network is delayed until the end of the ongoing transmission. The high efficiency wireless network uses an interframe space sufficiently short that a legacy network cannot contend for the medium. After the contention free period, the high efficiency network uses an interframe space value on the order of that used by the legacy network. 1. An apparatus comprising:at least one processor;memory storing a program of instructions;wherein the memory storing the program of instructions is configured to, with the at least one processor, cause the apparatus to at least:before the beginning of a priority period, examine a transmission medium for an ongoing transmission;in response to detection of an ongoing transmission from a second apparatus extending past the scheduled beginning of the priority period, wait for the fulfillment of a specified criterion indicating an end of the ongoing transmission;in response to fulfillment of the specified criterion, schedule transmission of the first data frame, followed by a first interframe space value after the ongoing transmission; andduring a non-priority period, schedule transmission of the first data frame, followed by a second interframe space value, wherein the second interframe space value is greater than the first interframe space value.2.

The third apparatus is configured to transmit signals at a rate, each signal being for enabling a wireless communication link to be established between the third apparatus and another apparatus (such as the first apparatus). In response to receipt of the second request, the third apparatus changes the rate at which the signals are transmitted.

Method and apparatus for synchronized channel access among groups

Номер: WO2013128072A1
Принадлежит: Nokia Corporation

In the detailed examples an access point AP assigns each of a plurality of stations to a group, in which at least one group has multiple stations assigned. For each group the AP sets a group-specific medium access interval during which stations who are members of the group are allowed to compete for medium access,and sends a message indicating the group-specific medium access intervals for the respective groups. A station receiving the message determines the group to which it belongs and determines that it is allowed to compete for medium access at least during the medium access interval. Various examples provide options for how the grouping might be made and how the intervals might be dynamically adjusted.

Принадлежит: Nokia Oyj

An approach for automating the provisioning of access credentials related to one or more shared resources to one or more user devices. An access rights platform determines one or more resources associated with at least one user, at least one device associated with the at least one user, or a combination thereof. The platform also processes social networking information associated with the at least one user, the at least one device, or a combination thereof to determine one or more social networking groups to which the one or more resources are associated. One or more access rights to the one or more resources for one or more other devices based, at least in part, on membership in the respective one or more social networking groups is then determined.
