Abstract
A network controller may schedule directional communications between two devices in its own network in such a way as to avoid potential interference from anticipated transmissions from another device. In some instances, the network controller may be one of the two devices using the directional communications. The timing of the anticipated transmissions may be determined by the network controller based on its own observations, or it may be informed of that timing in a transmission from a device in its own network. A possible format is given for transmitting that information to the network controller.
Claims22
An apparatus comprising a first wireless communications device having a processor, a memory, and a radio, the device configured to:
- determine a time period of potential interference in communications with a second wireless communications device, the interference to come from transmissions from a third wireless communications device, wherein the transmissions from the third wireless communications device is asynchronous with the second wireless communications device;
- derive information describing when the time period will occur with reference to a repeating beacon interval;
- create an information element containing values indicating a start time and a duration for the time period, the start time indicating a point of time within the beacon interval, wherein the information is contained in the information element;
- and
- transmit the information element to a network controller.
2 more elements
A method, comprising
- performing operations in a first wireless communications device, the operations comprising:
- determining a first time period and a second time period of potential interference in a subsequent communication with a network controller, the interference to come from asynchronous transmissions from a second wireless communications device with reference to the first wireless communications device;
- deriving information defining the first and second time periods with respect to a beacon interval, the information defining the first and second time periods as one or more periods to avoid communications between the first wireless communications device and the network controller;
- and
- transmitting the information to the network controller.
2 more elements
An article comprising
- a tangible computer-readable storage medium that contains instructions, which when executed by one or more processors result in performing operations comprising:
- determining, by a first wireless communications device, a time period of potential interference in subsequent communications involving a second wireless communications device, the interference to come from a third wireless communications device, wherein the transmissions from the third wireless communications device is asynchronous with the second wireless communications device;
- defining, by the first wireless communications device, the time period with respect to a beacon interval;
- creating, by the first wireless communications device, an information element containing values indicating a start time and a duration for the time period, the start time indicating a point of time within the beacon interval, wherein the information element is contained in the information;
- and
- transmitting, by the first wireless communications device, the information element to a network controller, the information element indicating the time period is a time period to avoid communications with the second wireless communications device.
