Abstract: Use is made of the Notice-of-Absence (NoA), as is a Wi-Fi/Bluetooth time sharing mechanism. This mechanism dictates ‘n’ cycles of absent and present duration of P2P-GO starting at a defined time ‘t’. The information bits of NoA are communicated from GO to the Client in the Beacons (for the period of NoA in use). Time-sharing between Bluetooth and WLAN at P2P-GO, is communicated using NoA to the P2P-Client. For the duration of both Bluetooth and WLAN radios transmitting/receiving traffic, NoA is used such that the absent duration covers the Bluetooth Interval and present-duration covers the WLAN interval. This NoA remains effective for as long as the time-sharing mode between BT and WLAN radios. As soon as, P2P-GO enters the time-sharing mode, NoA parameters are determined based on the timesharing mode (Dynamic Long and Dynamic Short). The start time of NoA schedule is determined after synchronizing to the time-sharing scheduler. The start time of NoA schedule is ‘n’ TBTTs after entering the time-sharing mode so that the Clients have ample opportunity to receive the NoA information. Until NoA schedule starts, P2P-GO may protect Bluetooth Interval using CTS2S frames. After NoA schedule comes into play, P2P-GO may send CTS2S only for asynchronous Bluetooth traffic.

Abstract: A method of wireless communication by user equipment (UE) identifies a coexistence issue corresponding to a set of communication resources of the UE. The UE transmits, to a base station, an indication of the coexistence issue. The UE receives, from the base station, a communication parameter for selectively scheduling a measurement gap pattern. The UE communicates in accordance with the measurement gap pattern to mitigate the coexistence issue.

Abstract: A method and apparatus for communicating in a wireless network includes an AP having multiple radios, a first one of which communicates with a nearby client node and a second one of which receives power on another wireless protocol operating in the same or close frequency band as the first radio. The first radio is configured to remotely control the transmit power of the client node so that it doesn't interfere with the reception performance of the second radio. A beacon or probe response frame is used to reduce transmit power of the client node and a CTS2S signal is used to selectively terminate client node transmit power entirely over short periods so that the reception performance of the other wireless device is not severely compromised or desensed by the client node and can be evaluated according to comparative performance criteria such as signal to interference plus noise ratio.

Abstract: This disclosure provides coexistence strategies for a combined wireless communications device using multiple wireless protocols, such as WLAN and LTE. Transmission power of a system using one wireless protocol is dynamically adjusted based on a determination of operating characteristics of a system using another wireless protocol. At least one of the operating characteristics may be determined from an allocation of network resources, examples of which include the transmission frequency for an upcoming transmission and the transmission power for an upcoming transmission. Further, the transmission power may be adjusted when the reception quality of the system using the other wireless protocol is below a desired threshold.

Abstract: A method of wireless communication includes adjusting a channel quality indicator (CQI) to compensate for coexistence interference experienced between communication resources (such as an LTE radio and a Bluetooth radio). The CQI may be set to zero, falsely indicating to a serving enhanced NodeB that a UE is out of range, thereby creating a gap in LTE operation that may be used by an alternate radio access technology. To compensate for fluctuating interference, the CQI may be adjusted to incorporate average coexistence interference over a period of time. Alternatively, the CQI at a time may incorporate coexistence interference regardless of whether interference is experienced at that specific time. A CQI value may also be boosted to compensate for a CQI backoff. CQI may be adjusted to avoid a spiral of death effect.

Abstract translation: 一种无线通信方法包括调整信道质量指示符（CQI）以补偿通信资源（例如LTE无线电和蓝牙无线电）之间经历的共存干扰。 CQI可以被设置为零，向服务增强型节点B虚拟地指示UE超出范围，从而在可能由替代无线电接入技术使用的LTE操作中产生间隙。 为了补偿波动的干扰，可以调整CQI以在一段时间内并入平均共存干扰。 或者，无论在该特定时间是否经历干扰，一次的CQI可以并入共存干扰。 还可以提升CQI值以补偿CQI回退。 可以调整CQI以避免死亡效应的螺旋。

Abstract: A communication control parameter for communicating via one technology is determined based on a communication schedule used in another technology. In some aspects, interference between a wireless local area network and a wireless wide area network is mitigated by appropriate selection of the communication control parameter. In some aspects, enhanced media access control features of IEEE 802.11ah are employed to facilitate co-existence between radio technologies. For example, interference may be mitigated through the use of a restricted access window, a target wake time, sectorized antennas, scheduled control information transmissions, and rate selection for control information.
