IEEE Standard for Local and Metropolitan Area Networks Part 16: Air Interface for Fixed Broadband Wireless Access Systems Draft Amendment: Management Information Base Extensions

A method and apparatus are described for integrating third generation partnership project (3GPP) radio access network and an Institute of Electrical and Electronics Engineers (IEEE) 802.11 radio access technologies (RATs). This may be done at a medium access control (MAC) layer or below the MAC layer. For example, a wireless transmit/receive unit (WTRU) for multiple radio access technology (RAT) integration includes a 3GPP RAT including a radio resource control (RRC) entity, an IEEE 802.11 RAT including a medium access control (MAC) management entity, and a session management entity (SME) for mapping between the RRC entity and the MAC management entity. Combined, hybrid and split versions of logical channel prioritization (LCP) are described. The features of an LTE access stratum-service management entity (AS-SME) are also described.

Systems and methods for mobile application traffic optimization are disclosed. In one aspect, embodiments of the present disclosure include a distributed proxy and cache system, including, a local proxy on a mobile device for intercepting a data request made via a mobile device, and a proxy server coupled to the mobile device and a content server to which the data request is directed. In one embodiment, the local proxy can forward the data request to the proxy server for transmission to the content server for a response to the data request. In addition, the proxy server sends the data request to the content server independent of activities on the local proxy and notifies the local proxy when changed or different content on the content server is detected for the data request. One embodiment of the distributed proxy and cache system further includes a cache shared between the local proxy and the proxy server and the component on the local proxy and is queried for a locally stored response to the data request prior to the data request being forwarded on to the proxy server.

Mobile application traffic optimization

A method and a communication system including femtocells within a macrocell efficiently manage interference between the different femtocells, and between each femtocell and a macrocell. An efficient frequency assignment scheme for the femtocells minimizes interference between a femtocell and a macrocell and among different femtocells using a spectrum-sensing technique carried out by the femtocells. The frequency assignment scheme selects a suitable channel from a set of candidate channels and ensures that the femtocell has an acceptable coverage area even when it is close to the macrocell base station (BS). The frequency assignment scheme favors a co-channel implementation to take advantage of the hand-off and cell search characteristics of the co-channel implementation. In one embodiment, a joint power control and frequency band assignment technique is used, which partitions the coverage area of the macrocell into an inner region, a power control region, and an outer region. Depending on a femtocell's location, it is assigned a certain power level and a frequency band. Power control may be used within the power-control region while, in the other regions, a fixed transmission power may be used.

A method for receiving a backoff value at a wireless station is presented. A traffic indication map is received at the station, wherein a backoff number is implicitly assigned to the station based on a position of the station within the traffic indication map. The backoff value is determined by multiplying the backoff number by a predetermined time value.

A method is provided for a device in a wireless communication network including a base station. The method includes sending a sleep mode request to the base station; and receiving a sleep mode response including negotiating parameters from the base station. The method also includes entering a sleep mode determined by a single power saving class applicable to all traffic conditions between the device and the base station; and communicating with the base station based on the sleep mode. Further, the single power saving class is used to define a frame structure for configuring frames to form alternating listening windows and sleep windows, to define an initial sleep window, and to define a default listening window.

A signal transmission method, and a base station and a wireless communication device using the same station identifier are provided. The signal transmission method is adapted for a M2M device, and includes the following steps. A M2M device is configured as either a follower device or a leader device, and the M2M device is grouped into a M2M device group comprising a leader device and n follower device, where n>=0. Moreover, a M2M contention region is periodically broadcasted in radio frames, where the follower device joins the M2M group by attaching to the leader device in the M2M device group during the M2M contention region. In addition, M2M devices in same M2M device group share same station identifier.
