A first portion of a physical layer (PHY) preamble of a PHY data unit is generated for transmission via a communication channel that comprises a plurality of sub-channels. A first portion of the PHY preamble is generated to include a legacy portion and a plurality of first non-legacy signal fields spanning the respective sub-channels. A second portion of a PHY preamble that immediately follows the first portion of the PHY preamble of the PHY data unit is generated to include: a non-legacy short training field spanning all sub-channels in the plurality of sub-channels, a plurality of non-legacy long training fields immediately following the non-legacy short training field, each non-legacy training field spanning all sub-channels in the plurality of sub-channels, and a second non-legacy signal field immediately following the plurality of non-legacy long training fields, the second-legacy signal field spanning all sub-channels in the plurality of sub-channels.

A method performed by a STA may comprise receiving, from an access point, a RTS frame having a duration field and transmitting, to the AP, in response to receiving the RTS frame, a CTS frame. The method may further comprise receiving, from the AP, data of a MU data unit addressed to the STA and another STA and, in response, transmitting an ACK frame, to the AP. The data may be received by the STA on a subset of sub-carrier frequencies of which the MU data unit spans and the MU data unit and the ACK frame may be transmitted within a duration indicated by the duration field.

According to one configuration, a mobile communication device receives first communications over a first wireless communication link from a first wireless network (which potentially supports data only communications). The first communications received over the first wireless network can include a message indicating a pending incoming call available over a second wireless network (which potentially supports voice/call communications). In response to receiving the message indicating the pending incoming call, the mobile communication device is operated to receive second communications (such as a paging signal) from over the second wireless network. For example, the mobile communication device listens for a paging signal from the second wireless network further indicating the pending incoming call. If desired, an operator of the mobile communication device can accept the incoming call via a second wireless communication link to the second wireless network.

An information management and synchronous communications system and method facilitates database equilibrium and synchronization with wired, wireless, and Web-based systems, user-friendly and efficient generation of computerized menus and reservations with handwritten/voice modifications for restaurants and other applications that utilize equipment with nonstandard graphical formats, display sizes and/or applications for use in remote data entry, information management and communication with host computer, digital input device or remote pager via standard hardwired connection, the internet, a wireless link, printer, or the like. Various operations employing automated telephone calls and/or messaging may, for instance, be performed. For example, desired reservation and/or appointment information may be automatically converted and conveyed to one or more entities via automated telephone call and/or messaging. As another example, information regarding reservation acceptability may be received and automatically converted via automated telephone can and/or messaging. Telephones may, for instance, be the only equipment required by the entities.

The invention relates to a method for operating a control entity (100) configured to influence a selection of one service instance (31) from a plurality of service instances provided by a distributed cloud system (30), each service instance providing a predefined service to a data packet flow of a user entity (60) connected to a mobile communications network. The method comprises monitoring a creation of new service instances providing the predefined service in the distributed cloud system (30), wherein for each new service instance a corresponding location in the distributed cloud system (30) is determined, determining, for each of the newly created service instances, location information indicating for each service instance a corresponding nearest access point to the mobile communications network, and transmitting the location information to the mobile communications network requesting to take into account the transmitted location information for a selection of a user plane entity (70) configured to transmit at least a user data plane of the data packet flow between the user entity (60) and one of the service instances.

A preamble of a physical layer (PHY) data unit that conforms to a first communication protocol is generated. The preamble includes a legacy field that is formatted according to a second communication protocol, and a signal field having a first orthogonal frequency division multiplexing (OFDM) symbol and a second OFDM symbol. The first OFDM symbol (i) immediately follows the legacy field and (ii) is modulated using binary phase shift keying (BPSK) modulation, whereas a third communication protocol specifies that an OFDM symbol, defined by the third communication protocol, that immediately follows the legacy field is modulated using BPSK modulation rotated by 90 degrees (Q-BPSK). The second OFDM symbol (i) immediately follows the first OFDM symbol and (ii) is modulated using Q-BPSK to indicate to a receiver device that conforms to the first communication protocol that the data unit conforms to the first communication protocol.
