Abstract: A method for active scanning in a wireless network may include two transmitters. In such a method, the following steps may take place: detecting a first probe request having a scanning target originating from a first transmitter; desiring to send a probe request to the scanning target from a second transmitter; and canceling the second probe request on a condition that the second transmitter detects the first probe request.

Abstract: A method for reporting power headroom is disclosed. Power headroom may be reported across all carriers (wideband), for a specific carrier, or for a carrier group. The formula used to calculate the power headroom depends on whether the carrier (or a carrier in the carrier group) has a valid uplink grant. If the carrier or carrier group does not have a valid uplink grant, the power headroom may be calculated based on a reference grant. The power headroom is calculated by a wireless transmit/receive unit and is reported to an eNodeB.
Abstract translation: 公开了一种用于报告功率余量的方法。 功率余量可以跨所有载波（宽带），特定载波或载波组报告。 用于计算功率余量的公式取决于载波（或载波组中的载波）是否具有有效的上行链路授权。 如果载波或载波组没有有效的上行链路许可，则可以基于参考许可来计算功率余量。 功率余量由无线发射/接收单元计算，并报告给eNodeB。

Abstract: A method performed by a station (STA) for operating in a wireless local area network (WLAN) is provided. A method may include receiving a beacon frame including an indication of a target wake time (TWT) period and a type indication that indicates single-user (SU) uplink (UL) transmission or multi-user (MU) UL transmission for the TWT period. The method may include receiving a trigger frame triggering a start of the TWT period. The STA may be awake during the TWT period. The method may include transmitting at least one frame during the TWT period. The at least one frame may be a SU uplink transmission or MU uplink transmission in accordance with the type indication.
