Abstract

An embodiment method for operating a network entity servicing one or more user equipments (UEs) includes transmitting a data file through one or more streams, wherein each of the one or more streams are carried on a multiple-user accessible channel. A configuration communication is provided to the one or more UEs regarding a relationship between content of the data file and the one or more streams such that each of the one or more UEs can receive the data file at different time instances according to the configuration communication.

First claim

What is claimed is:

1. A method for operating a network entity servicing user equipments (UEs) comprising:
transmitting, by the network entity, a data file through one or more streams to a plurality of UEs, wherein each of the one or more streams are carried on a multiple-user accessible channel, wherein a first stream in the one or more streams comprises multiple copies of at least one portion of the data file so that the at least one portion of the data file is transmitted repeatedly in the first stream and the plurality of UEs are able to receive the at least one portion of the data file without the need to synchronize with the first stream; and
providing a configuration communication to the plurality of UEs regarding a relationship between content of the data file and the one or more streams such that each of the plurality of UEs can receive the data file at different time instances according to the configuration communication.

2. The method of claim 1 , further comprising:
broadcasting availability of the data file.

3. The method of claim 1 , further comprising:
receiving one or more requests from the plurality of UEs for the data file.

4. The method of claim 1 , wherein the transmitting the data file comprises transmitting the data file through a plurality of streams, wherein each of the plurality of streams comprises multiple copies of a segment of the data file so that the segment is transmitted in a corresponding stream repeatedly.

5. The method of claim 1 , wherein the transmitting the data file comprises transmitting the data file through a plurality of streams, wherein each of the plurality of streams comprises multiple copies of an entirety of the data file so that the entirety of the data file is transmitted in a corresponding stream repeatedly, and wherein each of the plurality of streams transfers the data file with a different starting offset than one another.

6. The method of claim 1 , wherein the transmitting the data file comprises sending the data file through a plurality of streams, and wherein each of the plurality of streams comprises multiple copies an entirety of the data file so that the entirety of the data file is transmitted in a corresponding stream repeatedly, and each of the plurality of streams transfers the entirety of the data file with a different modulation and coding scheme than one another.

7. The method of claim 1 , further comprising:
receiving feedback from a first UE in the plurality of UEs related to downloading of the data file by the first UE.

8. The method of claim 7 , further comprising:
providing configuration information related to retransmitting data to the first UE of the plurality of UEs in response to the feedback from the first UE indicating that the data file is incomplete; and
transmitting at least some missing portions of the data file to the first UE.

9. A method for operating a user equipment (UE) for downloading data from one or more streams comprising:
receiving, by the UE, a first configuration communication from a network entity, the first configuration communication having information regarding a relationship between content of a data file transmitted to a plurality of UEs and the one or more streams for the UE to download the data file; and
receiving the data file from the network entity through the one or more streams and in accordance with the information regarding the relationship between the content of the data file and the one or more streams in the first configuration communication, wherein a first stream in the one or more streams comprises multiple copies of at least one portion of the data file so that the at least one portion of the data file is transmitted repeatedly in the first stream and the plurality of UEs are able to receive the at least one portion of the data file without synchronizing with the first stream; and
wherein the data file is received by the UE at a first time instance that is independent of a second time instance at which another UE can receive the data file.

10. The method of claim 9 , further comprising sending a request for the data file to the network entity prior to the receiving the first configuration communication.

11. The method of claim 9 , further comprising:
processing the received data file to determine whether the data file has missing portions; and
providing feedback to the network entity regarding the receiving the data file, the feedback comprising, in response to determining that the data file has the missing portions, information regarding the missing portions.

12. The method of claim 11 , further comprising receiving a second configuration communication related to retransmitting data in response to the providing the feedback and in response to the data file having the missing portions; and
wherein at least some of the missing portions are received according to the second configuration communication.

13. The method of claim 12 , wherein at least some of the missing portions are received from the network entity in a unicast transmission.

14. The method of claim 12 , wherein at least some of the missing portions are received from a transmission of the data file on a stream accessible to multiple users.

15. The method of claim 9 , wherein the data file is received through at least one stream of a plurality of streams, wherein each of the plurality of streams comprises multiple copies of a segment of the data file so that the segment is transmitted in a corresponding stream repeatedly.

16. The method of claim 9 , wherein the data file is received through at least one of a plurality of streams, and wherein each of the plurality of streams comprises multiple copies of an entirety of the data file so that the entirety of the data file is transmitted in a corresponding stream repeatedly and each of the plurality of streams transfers the data file with a different starting offset.

17. The method of claim 9 , wherein the data file is received through at least one of a plurality of streams, and wherein each of the plurality of streams comprises multiple copies of an entirety of the data file so that the entirety of the data file is transmitted in a corresponding stream repeatedly and each of the plurality of streams is transmitted on a multiple-user accessible channel.

18. A user equipment (UE) comprising:
an antenna;
a processor connected to the antenna and configured to transmit and receive data through the antenna; and
a non-transitory computer readable medium connected to the processor and having stored thereon instructions, that when executed, cause the processor to:
receive a first configuration communication from a network, the first configuration communication having information regarding a relationship between content of a data file and one or more of a plurality of streams carried in multiple-user accessible channels, wherein the data file is transmitted to a plurality of UEs in the one or more of the plurality of streams; and
receive the data file from the network in the one or more of the plurality of streams and according to parameters in the first configuration communication, wherein a first stream in the one or more of the plurality of streams comprises multiple copies of at least one portion of the data file so that the at least one portion of the data file is transmitted in the first stream repeatedly and the plurality of UEs receive the at least one portion of the data file without the need to synchronize with the first stream; and

wherein the data file is received by the UE at a first time instance that is independent
