Abstract
A wireless device () configures a carrier for communication with a serving access point (). The wireless device () maintains a virtual carrier sense timer. The virtual carrier sense timer indicates that the carrier is to be regarded as occupied as long as the virtual carrier sense timer is not expired. The wireless device () receives one or more wireless transmissions on the carrier. The one or more wireless transmissions each include: an identifier commonly assigned to multiple access points which cooperate by sharing a transmission opportunity, and a duration field for indicating a duration for which the carrier is expected to be occupied. In response to the identifier matching an identifier of the serving access point (), the wireless device () updates the virtual carrier sense timer according to the indicated duration. Based on the virtual carrier sense timer, the wireless device () controls one or more UL wireless transmissions from the wireless device ().
