US 2016/0261367 A1 · EARLY TERMINATION IN EMBMS RECEPTION

Abstract

Early termination of enhanced multimedia broadcast-multicast service (eMBMS) is discussed. Forward error correction (FEC) redundancy data is added to broadcast data, such that if enough of the data symbols are successfully received, the data object may be reassembled before the entire transmission has been received. The aspects involve an application processor and modem processor, which may either be integrated into the same integrated circuit or separate components. The application processor obtains a total number of source symbols and a redundancy level for a data object to be received from the eMBMS, receives the successfully received data symbols from the modem processor, and then determines whether the number of successfully received data symbols exceeds a threshold for reassembling the transmitted data object. If so, then the application processor and/or the modem processor can shut down until the next broadcast.

Dependent claims

A method of wireless communication, comprising:

obtaining, by an application processor, a total number of source symbols and a redundancy level for a data object to be received from a broadcast-multicast service;
receiving a plurality of received data symbols of the data object from the broadcast-multicast service via a modem processor associated with the application processor;
determining, by the application processor, that a number of the plurality of received data symbols exceeds a threshold data level greater than the total number of source symbols and less than a total number of data symbols for transmission of the data object, wherein the total number of data symbols comprises the total number of source symbols and a total number of redundancy symbols determined by the redundancy level;
and
signaling the modem processor to cease forwarding further received data symbols for the data object received from the broadcast-multicast service.

2 more elements

An apparatus configured for wireless communication, the apparatus comprising:

at least one processor;
and
a memory coupled to the at least one processor,
wherein the at least one processor is configured:
to obtain, by an application processor, a total number of source symbols and a redundancy level for a data object to be received from a broadcast-multicast service;
to receive a plurality of received data symbols of the data object from the broadcast-multicast service via a modem processor associated with the application processor;
to determine, by the application processor, that a number of the plurality of received data symbols exceeds a threshold data level greater than the total number of source symbols and less than a total number of data symbols for transmission of the data object, wherein the total number of data symbols comprises the total number of source symbols and a total number of redundancy symbols determined by the redundancy level;
and
to signal the modem processor to cease forwarding further received data symbols for the data object received from the broadcast-multicast service.

6 more elements

An apparatus configured for wireless communication, the apparatus comprising:

at least one processor;
and
a memory coupled to the at least one processor,
wherein the at least one processor is configured:
to successfully receive a plurality of data symbols for a data object transmission from a broadcast-multicast service at a modem processor;
to forward the plurality of successfully received data symbols to an application processor associated with the modem processor;
to receive a first modification signal from the application processor when a number of the plurality of successfully received data symbols exceeds a threshold data level greater than a total number of source symbols and less than a total number of data symbols for transmission of the data object;
and
to cease to forward any additional data symbols for the data object to the application processor in response to the first modification signal.
