Methods and apparatus for providing hybrid unicast broadcast services

摘要

A method, an apparatus, and a computer program product are provided in connection with facilitating hybrid unicast/broadcast service distribution. In one example, a communications device is equipped to provide a parity portion of titles in a channel of a service to a plurality of UEs at a first time, receive, from a UE at a second time, a request to access a title of the one or more titles, and provide an enablement item, to the requesting UE, which is a portion of the requested title that, when processed with the provided parity portion of the requested title, is sufficient to allow the requesting UE to decode and access to the requested title. In an aspect, the parity portion may be a parity portion of a fountain code encoded title, and the enablement item may be repair symbols of the fountain code encoded title.

1. A method of communications, comprising:
providing, to at least one user equipment (UE) of a plurality of UEs at a first time, a parity portion of one or more titles in a channel of a service, wherein the channel includes one or more titles and the service includes one or more channels, wherein the one or more titles are encoded with a code having a property that source symbols can be recovered from any subset of encoded symbols of size equal to or larger than a number of source symbols, K, wherein the parity portion comprises a subset of the encoded symbols less than K; receiving, from a UE of the plurality of UEs at a second time, a request to access a title of the one or more titles; and providing, to the requesting UE of the plurality of UEs, an enablement item, which is a portion of the requested title comprising additional encoded symbols that, when processed with the provided parity portion of the requested title, is sufficient to allow the requesting UE to decode and access the requested title.
