Abstract: A first station is configured to perform a method and system to transmit frames to a second station where the first station is associated with a first basic service set (BSS) and the method manages interference of the transmission amongst overlapping basic service sets (OBSSs). The first station detects a received frame on a wireless medium. The first station determines whether the received frame is from a second station, which is associated with a second BSS. The first station determines a received signal strength of the received frame. The first station determines that the received signal strength is below a first OBSS preamble detection level, where the first OBSS preamble detection level is associated with a first transmission power. The first station then sets the first transmission power as a maximum transmission power used by the first station for all frame transmissions during a time period.

Abstract: Mobile communication services that include voice calls, text messages, and internet are transitioning from circuit switched to packet switched networks such as internet. Although internet usage by mobile devices is on the rise, voice calls and text messages continue to be routinely and widely used. Most users at home or office may typically have phones that may be primarily based on wired connections. Although the eventual connection to the network may be wired, cordless phones may be used within the premises to connect with the base of the cordless phone which may connect to the wired network. A method and apparatus are disclosed that enable multi-user service with single broadband internet service in a base device and distribute the voice and text message service to the other users in the local premises. This may enable reduced cost and power consumption along with improved performance and user experience.

The network node obtains information on one or more of a frequency diversity, a time diversity of a channel between the network node and the communication device, an antenna spatial diversity of the communication device. The network node selects an MRS pattern out of a set of candidate patterns based on the received information, signals the selected MRS pattern to the communication device and transmits the MRS according to the selected MRS pattern.

Abstract: The present invention relates to a method and apparatus for controlling a handshake operation. Datagram Transport Layer Security (DTLS) is an important secure protocol in the IP based Internet of things. The performance of DTLS handshake can be significantly affected by network status, traffic and packet loss rate, etc. It is therefore suggested evaluating a package loss rate and estimating causes of packet loss. Then, a DTLS handshake strategy may be changed adaptively based on the detection of packet loss and network status. As a result, the successful rate and delay of DTLS handshake can be improved. An acknowledgement and a non-acknowledgement mode may be used in a hybrid way to evaluate the package loss rate and estimate causes of packet loss and eventually improve performance of DTLS handshake.

Abstract: A communication apparatus has a communication function for performing wireless communication using one of a first mode of performing first communication with a partner apparatus via another apparatus, a second mode of performing second communication with the partner apparatus not via another apparatus, and a third mode of concurrently performing the first communication and the second communication.

The second message comprises the feedback relating to the connection sent from the UE in response to the first message. Then it is evaluated how the connection shall be used based on the obtained time value difference and the received feedback.
