摘要： A method of spatial reuse with opportunistic transmit power control (TPC) and clear channel assessment (CCA) is proposed. In the opportunistic TPC and CCA, a spatial reuse station (SR-STA) gains enough knowledge in certain situation for more aggressive spatial reuse such that its transmit power may be adjusted to meet the spatial reuse conditions based on the received OBSS PPDU and the corresponding spatial reuse parameter (SRP). Both Type 1 SRP and Type 2 SRP are defined. In one example, the Type 1 or Type 2 SRP is a 5-bit parameter carried in the HE-SIG-A field of the OBSS PPDU, which can be a trigger frame, a response frame, a request-to-send (RTS)/clear-to-send (CTS) frame, and a data frame.

摘要： A unified channel contention scheme is proposed such that spatial reuse can be enabled by a wireless station (STA) when a basic service set (BSS) color of a received signal cannot be resolved. If the detected frame is an intra-BSS frame, then the STA should not contend the channel for the PPDU duration. If the detected frame is an inter-BSS frame, then the STA uses OBSS Packet Detection (OBSS-PD) level as the CCA level for channel contention. Furthermore, when BSS color cannot be resolved, channel contention schemes for WiFi signal and non-WiFi signal are differentiated. If the received signal is detected as WiFi signal, then the STA uses WiFi-SIG Detection (WD) level as the CCA level for channel contention. If the received signal is detected as non-WiFi signal, then the STA uses Non-WiFi-SIG Detection (NWD) level as the CCA level for channel contention.
摘要翻译：提出了一种统一的信道争用方案，使得当接收信号的基本服务集（BSS）颜色不能被解析时，可以由无线站（STA）使能空间重用。如果检测到的帧是BSS内帧，则STA不应该对该PPDU持续时间进行竞争。如果检测到的帧是BSS间帧，则STA使用OBSS分组检测（OBSS-PD）级作为CCA级别进行信道争用。此外，当BSS颜色不能解决时，WiFi信号和非WiFi信号的信道争用方案是有区别的。如果接收到的信号被检测为WiFi信号，则STA使用WiFi-SIG检测（WD）级作为用于信道争用的CCA级别。如果接收到的信号被检测为非WiFi信号，则STA使用非WiFi-SIG检测（NWD）级作为用于信道争用的CCA级别。

摘要： Methods and apparatus are provided for clear channel assessment in the Wifi network. In one novel aspect, different clear channel assessment (CCA) threshold value is set for intra-BSS and inter-BSS frames during the counting down process. A CCA procedure senses the radio channel and determines if the radio channel is busy or idle during the backoff period by comparing the signal level value of detected fames with the CCA threshold value. The counting down will be suspended if the radio channel determined to be busy. If the detected frame is inter-BSS frame, the CCA threshold value is raised. If the signal level of the detected frames is lower than the inter-BSS CCA threshold for inter-BSS fames, the radio channel is considered idle. The counting down process is resumed.

摘要： Systems and methods of transmitting and receiving a Wake-Up Radio (WUR) packet by using a simplified preamble structure that contains no training field. The preamble carries a signature sequence selected from a set of predefined sequences, each corresponding to a different data transmission rate. The preamble and the control information of the WUR packet are transmitted in the same rate as indicated by the selected sequence. Hence, a receiving WUR can determine the data transmission rate and locate the associated control information directly if a sequence that matches a predefined signature sequence is detected. The same sequence or in combination with an additional sequence in the preamble may also be used to indicate automatic gain control synchronization, packet type and other related information.
