Abstract: Methods, devices, and systems for the transmission of information in a wireless communication system are disclosed. In one embodiment, a method for the transmission of information in a wireless communication system comprises receiving a downlink message, wherein the downlink message includes a first control channel element; determining a first index using the location of the first control channel element; determining a second index; determining a first orthogonal resource using the first index; determining a second orthogonal resource using the second index; spreading an uplink message using the first orthogonal resource to form a first spread signal; spreading the uplink message using a second orthogonal resource to form a second spread signal; transmitting the first spread signal using a first antenna; and transmitting the second spread signal using a second antenna.

Abstract: Methods and electronic devices for sharing a camera feature are described. In one aspect, the present disclosure describes a method. The method is performed by a first electronic device which has a camera. The method includes: establishing wireless communications between the first electronic device and a second electronic device using a short range communication module of the first electronic device; and entering a camera-feature-sharing mode in which a camera-related feature of the second electronic device is accessible to the first electronic device using the short range communication module and in which a camera-related feature of the first electronic device is accessible to the second electronic device using the short range communication module.
