1. A method comprising:
- receiving, by a base station, a quality of service (QoS) request for a flow from a mobile station via one or more relay stations in a wireless relay network, the QoS request including one or more of traffic priority, maximum sustained traffic rate, maximum traffic burst, tolerated jitter, and maximum latency;
in response to receiving the QoS request, the base station sending an admission control (AC) request message to request an AC decision from the one or more relay stations;
receiving, by the base station, an AC response for the flow to either admit or reject the flow based on the QoS request from the one or more relay stations in the network along a path; and
making, by the base station, an admission control decision for the flow to either admit or reject the flow based at least in part upon the AC response(s) from the one or more relay stations,wherein the QoS request includes a service flow identifier (SFID) to identify an associated service flow and one or more QoS parameters identifying a requested QoS for the associated service flow.

Abstract
Various embodiments are described relating to wireless networks, such as quality of service (QoS) request and information distribution for wireless relay networks. According to an example embodiment, a technique or method may include receiving a QoS-related message at a relay station in a wireless relay network. The QoS-related message may include one or more QoS parameters for a flow. The method or technique may also include retrieving, at the relay station, the QoS parameters from the QoS-related message to use the QoS parameters subsequently for admission control and/or scheduling for the flow. Other example embodiments are described.
