An access point operates in an 802. 11 wireless communication network communicating with a client station, and includes a smart antenna for generating directional antenna beams and an omni-directional antenna beam. An antenna steering algorithm scans the directional antenna beams and the omni-directional antenna beam for receiving signals from the client station. The signals received via each scanned antenna beam are measured, and one of the antenna beams is selected based upon the measuring for communicating with the client station. The selected antenna beam is preferably a directional antenna beam. Once the directional antenna beam has been selected, there are several usage rules for exchanging data with the client station. The usage rules are directed to an active state of the access point, which includes a data transmission mode and a data reception mode.

An access point receives uplink transmissions from client stations using directional antenna beams. The directional antenna beams are generated by an antenna array. The different directional antenna beams are assigned beam identification numbers, and a preferred antenna beam is selected for each client station. The client stations in the different antenna beam regions initiate their uplink transmissions using assigned backoff slots within the contention window. The access point selects the preferred directional antenna beam corresponding to the directional antenna beams assigned to the backoff slots.

A method and apparatus for supporting communication buffer status reports (BSRs) are disclosed. A wireless device may generate a first buffer status report (BSR) associated with first data for transmission to at least one wireless transmit/receive unit (WTRU). Also, the wireless device may generate a second BSR associated with second data for transmission to a base station. Further, the wireless device may transmit the first BSR and the second BSR in a media access control (MAC) protocol data unit (PDU) to the base station. Additionally, the wireless device may transmit the first data to the at least one WTRU. Moreover, the wireless device may transmit the second data to the base station. In a further example, the wireless device may generate the first BSR and generate the second BSR are based on a priority associated with the first BSR and a priority associated with the second BSR.

A method and apparatus for supporting communication buffer status reports (BSRs) are disclosed. A wireless device may receive from an eNode-B a first indication indicating a logical channel group and at least one associated priority. The wireless device may produce a BSR associated with first data, which may include an indication associated with the logical channel group and an index indicating an amount of the first data. The wireless device may transmit the BSR to an eNode-B. Then, the wireless device may receive receives allocation information for transmission to a wireless transmit/receive unit (WTRU) group. Further, the wireless device may transmit at least a portion of the first data to the WTRU group over a logical channel in the logical channel group. Also, the BSR may further include a plurality of indications associated with a respective plurality of logical channel groups.

A wireless device may transmit data to a wireless transmit/receive unit (WTRU) group, which may include a WTRU and further include its own respective at least one logical channel group. The wireless device may produce a BSR, which may include an indication associated with the logical channel group and an index indicating an amount of data for the logical channel group. The wireless device may transmit the BSR to an eNode-B. Then, the wireless device may receive receives allocation information for transmission to the WTRU group. Also, the BSR may further include a plurality of indications associated with a respective plurality of logical channel groups, and the plurality of logical channel groups may be grouped based on priority. The index may further include a total amount of data across all logical channels of the logical channel group.

Methods and apparatus are described for transmitting and receiving data by a wireless transmit/receive unit (WTRU) over the control plane. The methods may receive data without the use of an Internet Protocol (IP) address. In an example method, a WTRU may enter an evolved packet system (EPS) mobility management (EMM)-registered control plane only (CPO) state after receiving an attach accepted message for CPO operation, and enter an EMM-deregistered state after receiving a detach message, a tracking area update (TAU) reject message or an attach reject message. In another method, a WTRU may switch between operational modes that use an IP address and a user plane to transmit and receive data, and the CPO mode.

A method and apparatus are described for controlling the application of Selected Internet Protocol (IP) traffic offload (SIPTO) or Local IP Access (LIPA) services for a wireless transmit/receive unit (WTRU). The SIPTO and LIPA services may be performed over packet data network (PDN) connections. A user of the WTRU may be prompted to accept or reject the usage of the SIPTO or LIPA services. The user of the WTRU may request switching from SIPTO or LIPA services to non-SIPTO or non-LIPA services.
