Abstract:
1. A method, comprising: communicating, by a wireless device, with an associated access node, in a first time window allocated to a group of wireless devices associated with the associated access node in a sector, the wireless device being a member of the group of wireless devices, based on reception by the wireless device of a directional beacon frame from the associated access node in the sector; receiving by the wireless device, a measurement request from the associated access node, to perform measurement of at least one signal received in the sector from at least one other access node to which the wireless device is not associated; receiving, by the wireless device during measurement in response to the measurement request, a directional message in the sector, with an access node identifier of another access node to which the wireless device is not associated and determining a reception power of the directional message; transmitting, by the wireless device, to the associated access node, in response to the measurement request, a measurement response comprising information on the directional message in the sector; and receiving, by the wireless device, from the associated access node, an indication of a second time window that may be used by the wireless device for transferring data between members of the group of wireless devices in the sector and the associated access node, based at least partly on the information in the measurement response, the second time window providing channel protection in the sector for directional transmission in one or more directions, to avoid or reduce effects of interference by directional messages in the sector.
