Method and apparatus for plug-and-play venue-cast co-channel with wide-area network
First Claim
1. A venue-cast transmitter comprising:
- a receiver configured to receive a forward link signal comprising a timing reference for data transmitted on a wireless access network and to obtain a logical channel mapping for the wireless access network, the logical channel mapping being indicative of a dynamic allocation of at least one vacated time slot in the forward link signal;
a transmitter configured to transmit a data signal comprising venue-cast content in a same frequency band as the forward link signal; and
a processor coupled to the transmitter and the receiver and configured to detect the at least one vacated time slot in the forward link signal based on the timing reference and the logical channel mapping and to output the data signal during an interval defined by the at least one vacated time slot.

Abstract
A system, method, and apparatus for providing venue-cast service in a wireless access network are disclosed. A local transmitter can request reservation of air link resources on the wireless access network for a venue-cast transmission. The local transmitter can receive a forward link signal with a timing reference for data transmitted on the wireless access network such as, for example, the forward link signal in an EV-DO network or a FLO-based media distribution system. Based on the timing reference, the local transmitter can transmit venue-cast information in a same frequency band as the forward link signal utilizing the reserved air link resources. Optionally, the venue-cast system can include a collocated network repeater and the local transmitter can synchronize its timing and transmit power to the forward link signal from the repeater.

13. A method of providing venue-cast content with a local transmitter within a coverage area of a wireless access network, the method comprising:
-
receiving venue-cast content at a first interface of the local transmitter; receiving a forward link signal of the wireless access network at a second interface of the local transmitter; obtaining a logical channel mapping for the wireless access network, wherein the logical channel mapping is indicative of a dynamic allocation of at least one vacated time slot in the forward link signal; detecting in the forward link signal a timing reference for data transmitted on the wireless access network; detecting the at least one vacated time slot in the forward link signal based on the timing reference and the logical channel mapping; and transmitting a second signal comprising the venue-cast content in a same frequency band as the forward link signal during an interval defined by the at least one vacated time slot. - View Dependent Claims (14, 15, 16, 17)

18. A localized content transmission system, comprising:
-
a repeater configured to replicate a forward link signal of a wireless access network; a receiver configured to receive the forward link signal from the repeater, to detect a timing reference for data transmitted on the wireless access network, and to obtain a logical channel mapping for the wireless access network, the logical channel mapping being indicative of a dynamic allocation of at least one vacated time slot in the forward link signal; a transmitter configured to transmit a data signal including localized content in a same frequency band as the forward link signal; and a processor configured to detect the at least one vacated time slot in the received forward link signal based on the timing reference and the logical channel mapping and to output the data signal to coincide with the at least one vacated time slot. - View Dependent Claims (19, 20, 21, 22, 23, 24)

25. A venue-cast system, comprising:
-
means for receiving a forward link signal of the wireless access network; means for repeating the forward link signal; means for detecting a timing reference for data transmitted on the wireless access network in the repeated signal; means for obtaining a logical channel mapping for the wireless access network, wherein the logical channel mapping is indicative of a dynamic allocation of a vacated time slot in the forward link signal; means for determining the arrival of the vacated time slot in the forward link signal based on the timing reference and the logical channel mapping; and means for transmitting a second signal comprising localized content in a same frequency band as the forward link signal of the wireless access network based on the timing reference and the logical channel mapping during an interval defined by the vacated time slot. - View Dependent Claims (26, 27, 28, 29)
