    • 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.

    • In one embodiment, in absence of transmitting from an apparatus a reservation request frame, the apparatus receives a reservation response frame on an assigned channel. The reservation response frame indicates a duration of a frame transmission. In response to receiving the reservation response frame, the apparatus transmits a frame on the assigned channel during the frame transmission. In another embodiment, in response to receiving a reservation request frame on a first channel at an apparatus, the apparatus transmits a reservation response frame on the first channel and on at least one second channel. The reservation request frame indicates a duration of a frame transmission. The reservation response frame indicates the duration of the frame transmission. After transmitting the reservation response frame, this apparatus receives during the frame transmission a first frame on the primary channel and a second frame on the at least one secondary channel.
    • 在一个实施例中,在没有从装置发送预留请求帧的情况下,装置在分配的信道上接收预留响应帧。 预约响应帧指示帧传输的持续时间。 响应于接收到预约响应帧,该装置在帧传输期间在所分配的信道上发送一帧。 在另一个实施例中,响应于在设备处的第一信道上接收到预留请求帧,该设备在第一信道上和至少一个第二信道上发送预留响应帧。 预留请求帧指示帧传输的持续时间。 预约响应帧指示帧传输的持续时间。 在发送预留响应帧之后,该装置在帧传输期间接收主信道上的第一帧和至少一个次信道上的第二帧。

    • Method, apparatus, and computer program product embodiments are disclosed to improve network performance for ad hoc network initiation. Example embodiments include a new operational sequence for wireless devices initiating the use of an ad hoc network. The example embodiments require appropriately enabled wireless devices to only respond to probe request frames from other similarly appropriately enabled wireless devices. In this manner, two devices may avoid the time consuming effort of combining two different ad hoc networks into a single ad hoc network so that the two devices can communicate.
