LTE based multicast in unlicensed spectrum

摘要

Methods, systems, and devices are described for broadcast signal transmission using a number of nodes in an unlicensed spectrum. A set of nodes may be identified for use in transmission of a broadcast signal, with a first subset of the nodes transmitting the broadcast signal to deliver first content during a first time period, and with a second subset of the nodes transmitting the broadcast signal to deliver second content during a second time period. The first subset of nodes is different than the second subset of nodes. The set of nodes may thus form a single frequency network (SFN) that performs partial SFN operation during the first and second time periods.

1. A method for wireless communications, comprising:
receiving broadcast signals delivering first content from a first subset of a plurality of nodes, the first subset of nodes transmitting the broadcast signals as a supplemental downlink carrier in an unlicensed spectrum during a first time period; receiving the broadcast signals delivering second content from a second subset of the plurality of nodes, the second subset of nodes transmitting the broadcast signals as the supplemental downlink carrier in the unlicensed spectrum during a second time period, wherein the first subset of nodes is different from the second subset of nodes; receiving, from a serving node on a licensed spectrum, system information indicating a location of a control channel for the broadcast signals; and receiving, from one or more nodes of the plurality of nodes, the control channel on the licensed spectrum.
