A transmitting method includes: configuring a frame using a plurality of orthogonal frequency-division multiplexing (OFDM) symbols, by allocating a plurality of transmission data to a plurality of areas; and transmitting the frame. The plurality of areas are each identified by at least one time resource among resources and at least one frequency resource among frequency resources. The frame includes a first period in which a preamble is transmitted, and a second period in which the plurality of transmission data are transmitted by at least one of time division and frequency division. The second period includes a first area, and the first area includes a data symbol generated from first transmission data, a data symbol generated from second transmission data and subsequent to the data symbol generated from the first transmission data, and a dummy symbol subsequent to the data symbol generated from the second transmission data.

Methods and apparatuses are provided to modify existing overlay system architectures in a cost effective manner to meet the growing demand for narrowcast services and to position the existing overlay systems for additional future modifications. The implementations of the improved overlay system of this disclosure re-digitize narrowcast analog signals after they have been QAM modulated and upconverted to RF frequencies and replace the analog narrowcast transmitters with digital narrowcast transmitters. In the fiber nodes, the received narrowcast signals are converted back to analog signals and combined with analog broadcast signals for transmission to the service groups.

A discovery and provisioning method. The method includes: A first device in an unprovisioned state sends a first message through a first antenna, where the first message is used by a second device to discover the first device, and the first message includes a device identifier of the first device; when a distance between the second device and the first device is less than or equal to a preset distance, the second device receives the device identifier sent by the first device; and after being discovered by the second device, the first device performs provisioning by using a second antenna.

This document describes methods, devices, and systems for configuring a smartphone (102) for network connectivity via a charging station (120), in which the smartphone (102) detects a connection or a coupling to the charging station (120). In response to the detection of the connection or coupling to the charging station (120), the smartphone (102) configures a WLAN transceiver (228) as a WLAN access point and forms a mesh WLAN network with one or more other WLAN access points (114). In other aspects, the charging station (120) detects the presence of the smartphone (102) that is connected or coupled to the charging station (120). In response to sensing the presence of the smartphone (102), the charging station (120) configures power and charging circuitry (244) to charge a battery of the smartphone (102) and configures WLAN radio circuitry (232) to relay WLAN communications for the smartphone (102).

Mechanisms are provided for a user equipment (UE) to determine to use a shared resource such as an antenna to access a land based wireless communication system or a satellite communication system. The UE can provide a first priority indication to indicate whether to access the land based wireless communication system based on one or more wireless link metrics of the land based wireless communication system or one or more application metrics for applications using the land based wireless communication system; and provide a second priority indication to indicate whether to access the satellite wireless communication system based on one or more service metrics provided by the satellite wireless communication system. The UE can determine to use the shared resources to access the land based wireless communication system or the satellite communication system based on the first priority indication and the second priority indication.
