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.

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.

Embodiments contemplate paging and system information broadcast handling for multi-SIM WTRUs using mobile networks to access resources and/or services. Embodiments also contemplate paging and system information broadcast handling for multi-SIM WTRUs and/or non-SIM WTRUs using mobile networks to access virtualized resources and/or services. Embodiments contemplate that a WTRU may determine to monitor a plurality of mobile networks. Paging occasions to monitor at least one of the mobile networks may be based on a common WTRU ID. The WTRU ID may be provided by a node supporting access to the virtualized resources or services. Paging occasions for a first network may be determined by a second network based on paging related parameters and other information of the first communication network. A change in system information of a first network may be signaled to a second network for indication to a WTRU.

Methods and apparatus are disclosed for a wireless transmit/receive unit (WTRU) to perform a multi-radio access technology (RAT) access (MRA) operation. The apparatus may include a WTRU non-access stratum (NAS) entity to communicate with a first and second NAS entity of a first and second core network (CN). Alternatively, the first WTRU NAS entity communicates with a first NAS entity of a first CN, and a second WTRU NAS entity communicates with a second NAS entity of a second CN. The apparatus may include a radio resource control (RRC) entity which controls a first RAT connected to the first CN and a second RAT connected to the second CN. Alternatively, the apparatus includes an RRC entity which controls a first connection using a first RAT connected to the first CN and a second connection using a second RAT connected to a second CN.
