Abstract: In some aspects, the disclosure is directed to methods and systems for coexistence management. A first access point is scheduled a time to begin transmission of a packet to a user device in an unlicensed frequency band using a first RAT. The time to begin the transmission is scheduled to avoid transmission overlap with a second access point using a second RAT in the unlicensed frequency band, and scheduled according to information from the second access point regarding operation in the unlicensed frequency band using the second RAT. One of the first and second RATs includes one of a WLAN RAT or a LTE based RAT, and another of the first and second RATs includes a remaining one of the WLAN RAT or the LTE based RAT, in one or more embodiments. The first access point receives updated information regarding operation in the unlicensed frequency band using the second RAT. Using the updated information, an updated time for the first access point to begin the transmission using the first RAT is determined, the updated time determined to avoid transmission overlap with the second RAT in the unlicensed frequency band. The first access point transmits, according to the determined updated time, the packet in the unlicensed frequency band using the first RAT.

Abstract: In some aspects, the disclosure is directed to methods and systems for coexistence management. A first access point operating in an unlicensed frequency band using a first RAT receives, from a second access point operating in the unlicensed frequency band using a second RAT, information regarding operation of the second access point in the unlicensed frequency band. It is determined, using the received information, that the first access point or the second access point is using a first share of the unlicensed frequency band that is below a predetermined threshold, indicating an imbalance of usage between the first RAT and the second RAT. A transmission parameter of the first access point for operating in the unlicensed frequency band using the first RAT is adjusted according to the determination. The first access point transmits the one or more packets using the adjusted transmission parameter, to cause the first access point or the second access point to use an updated share of the unlicensed frequency band that is closer to the predetermined threshold than the first share.

Abstract: Methods and systems that support, for example, canceling or trimming reservations of a shared communication medium are described. In one embodiment, a method that adapts a network time reservation in a communication network may include, for example, one or more of the following: transmitting a preamble field; transmitting a legacy signal field; transmitting at least one paired field, each paired field comprising a signal field and a protocol data unit; and generating an interframe gap.
Abstract translation: 描述支持例如取消或修剪共享通信介质的预留的方法和系统。 在一个实施例中，适应通信网络中的网络时间预留的方法可以包括例如以下中的一个或多个：发送前导字段; 传输遗留信号字段; 发送至少一个配对场，每个成对场包括信号场和协议数据单元; 并产生帧间间隔。
