Abstract: A user terminal for multiple-user wireless communication is provided, comprising a transmit buffer configured to store uplink data for transmission. The user terminal comprises a processor configured to generate a request to transmit frame in response to uplink data being present in the transmit buffer, and initiate a transmit timer for determining when to transmit the request to transmit frame. The user terminal comprises a transmitter configured to transmit the request to transmit frame when the transmit timer expires or when the uplink data present in the transmit buffer exceeds a threshold amount. The user terminal comprises a receiver configured to receive a clear to transmit frame from an access point based on the transmitted request to transmit frame. The transmitter is further configured to transmit the uplink data present in the transmit buffer, concurrently with at least one other user terminal transmitting uplink data, to the access point at a specified time based on receiving the clear to transmit frame addressed to the user terminal.

Abstract translation: 提供了一种用于多用户无线通信的用户终端，包括配置为存储用于传输的上行链路数据的发射缓冲器。 用户终端包括处理器，该处理器被配置为响应于上行链路数据出现在发送缓冲器中而生成发送帧的请求，并发起用于确定何时发送发送帧请求的发送定时器。 用户终端包括发射机，该发射机被配置为当发射定时器到期时或者当发射缓冲器中存在的上行链路数据超过阈值量时发送对发送帧的请求。 该用户终端包括接收机，该接收机被配置为基于所发送的传输帧请求来从接入点接收清除传输帧。 所述发射机还被配置为基于接收到寻址到所述用户终端的所述清除发射帧，在指定时间将存在于所述发射缓冲器中的所述上行链路数据与发射上行链路数据的至少一个其他用户终端同时发送到所述接入点。

Abstract: Disclosed is a portable token device that may be used to assist a user in generating a PIN at one device and to then pass the PIN to another device such that the two devices can securely communicate with one another. The portable token device may include: an interface; and a processor. The processor may execute operations including: determining if a close proximity coupling through the interface to a first device has occurred; transmitting a PIN request to the first device; and obtaining a PIN. Further, the processor may determine if a close proximity coupling through the interface to a second device has occurred. If so, the processor may command transmitting the PIN to the second device. The second device may perform device registration with the first device based upon the received PIN.
