  • Patent number: 10420030
    Abstract: A method for operating in a power save mode for a wireless local area network and a device using the same are provided. After waking up, a device receives a frame via a wireless medium to determine that the wireless medium is busy. If a decoding of the frame in a medium access control (MAC) layer is unsuccessful but a decoding of the frame in a physical layer is successful, the device determines an Interframe space (IFS) to defer an access of the wireless medium.

  • Patent number: 9992783
    Abstract: A Device-to-device (D2D) user equipment (UE) device communicating with another D2D UE device within a first cell transmits a D2D subframe that includes a cell identifier a second cell when the UE device moves from the first cell to the second cell. After a handover to the second cell is initiated, the D2D UE device can suspend D2D communication. The D2D UE device transmits the D2D subframe, such as D2D discovery subframe, identifying the second cell when the handover is complete. The other D2D UE device identifies the second cell to the base station providing the first cell. The base stations providing the first cell and the second cell coordinate to determine resources for D2D communication between the D2D UE devices.

  • Patent number: 9980310
    Abstract: A method of enhanced session management procedure is proposed. A user equipment, upon receiving a rejected PDN connectivity request with a cause code, automatically alters the rejected factor to fit network restrictions based on the received cause code. The UE then retries the PDN connectivity procedure by sending a subsequent PDN connectivity request using the altered factor. By automatically altering the rejected factor and reattempting to establish an EPS bearer for data service without user interaction, possible permanent rejection can be avoided in case of user error or unawareness.
