Abstract

A method performed by a radio base station, the method including receiving streaming data information, the data information includes a first portion from a first set of antenna carriers and a second portion from a second set of antenna carriers, wherein the first portion is to be processed prior to the second portion. The method further including streaming the first portion of the data information from a radio equipment control device in a first data frame over an interface link that is configured to operate based on a first mapping configuration that indicates a set of locations of the first data frame at which the first portion of information is to be streamed, and streaming the second portion of the data information from the REC device in a second data frame over the interface link that is configured to operate based on a second mapping configuration.

Claims

1. A method comprising:

receiving streaming data, the data includes a first portion from a first set of antenna carriers and a second portion from a second set of antenna carriers, wherein the first portion is to be processed prior to the second portion, and the first set of antenna carriers is different than the second set of antenna carriers;

streaming the first portion from a radio equipment control (REC) device in a first data frame of a plurality of data frames over an interface link when configured to operate based on a first mapping configuration that indicates a set of locations of the first data frame at which each antenna carrier of the first set of antenna carriers is to be streamed; and

streaming the second portion from the REC device in a second data frame of the plurality of data frames over the interface link when configured to operate based on a second mapping configuration that indicates a different set of locations of the second data frame at which each antenna carrier of the second set of antenna carriers is to be streamed, wherein the first and second data frames are contiguous data frames.

2. The method of claim 1, further comprising:

transmitting from the REC device for reception by a radio equipment (RE) device, prior to streaming the second portion of the data, the second mapping configuration and an indicator identifying when the interface link is to change operation based on the second mapping configuration.

3. The method of claim 2, wherein the indicator is a specific frame number used to identify the second data frame of the plurality of data frames.

4. The method of claim 2, further comprising:

configuring, prior to streaming the second portion of the data, a shadow register of the REC device based on the second mapping configuration.

5. The method of claim 4, further comprising:

updating registers of the REC device with values at the shadow register to cause the operation of the interface link to change to operate based on the second mapping configuration in response to determining that the indicator identifies that the operation of the interface link is to be changed.

6. The method of claim 3, wherein the specific frame number indicates that the second data frame is next data frame to be sent over the interface link.

7. The method of claim 1, wherein at least one antenna carrier when transmitted over the first data frame has a first amount of data, and the at least one antenna carrier when transmitted over the second data frame has a second amount of data.

8. The method of claim 1, wherein the interface link comprises one or more of a common public radio interface (CPRI) and an open base station architecture initiative (OBSAI) interface.

9. A radio equipment control system comprising:

a radio equipment control (REC) device coupled to an interface link, the REC device to;

store a stream of data, the data includes a first portion from a first set of antenna carriers and a second portion from a second set of antenna carriers, wherein the first portion is to be processed prior to the second portion, and the first set of antenna carriers is different than the second set of antenna carriers;

a framer to frame the first portion in a first data frame of a plurality of data frames for streaming over the interface link, the first data frame based on a first mapping configuration that indicates a set of locations of the first data frame at which antenna carriers of the first portion is to be streamed and to frame the second portion in a second data frame of the plurality of data frames for streaming over the interface link, the second data frame based on a second mapping configuration that indicates a different set of locations of the second data frame at which antenna carriers of the second portion is to be streamed, wherein the first and second data frames are contiguous data frames.

10. The radio equipment control system of claim 9, wherein the REC device is further to:

transmit, prior to the first frame, the second mapping configuration for reception by a RE device and an indicator identifying when the interface link is to change operation based on the second mapping configuration.

11. The radio equipment control system of claim 9, wherein the REC device is further to:

configure, prior to framing the second portion, a shadow register of the REC device based on the second mapping configuration.

12. The radio equipment control system of claim 11, wherein the REC device is further to:

update, prior to framing the second portion, registers of the REC device with values at the shadow register of the REC device to cause the operation of the interface link to change to frame the second portion based on the second mapping configuration in response to determining that the indicator identifies that the operation of the interface link is to be changed.

13. The radio equipment control system of claim 9, wherein the indicator is a specific frame number used to identify the second data frame of the plurality of data frames.

14. The radio equipment control system of claim 13, wherein the specific frame number indicates that the second data frame is next data frame to be sent over the interface link.

15. The radio equipment control system of claim 9, wherein the interface link comprises one or more of a common public radio interface (CPRI) and an open base station architecture initiative (OBSAI) interface.

16. A method comprising:

receiving by a radio equipment (RE) device a first portion of streaming data from a first set of antenna carriers in a first data frame of a plurality of data frames over an interface link when configured to operate based on a first mapping configuration that indicates a set of locations of the first data frame at which each antenna carrier of the first set of antenna carriers is to be received; and

receiving by the RE device a second portion of streaming data from a second set of antenna carriers in a second data frame of a plurality of data frames over the interface link when configured to operate based on a second mapping configuration that indicates a different set of locations of the second data frame at which at which each antenna carrier of the second set of antenna carriers is to be received, wherein the first and second data frames are contiguous data frames, the first portion is to be processed prior to the second portion, and the first set of antenna carriers is different than the second set of antenna carriers.

17. The method of claim 16, further comprising:

receiving by the RE device from a transmission by a radio equipment control (REC) device, prior to receiving the second portion of the data, the second mapping configuration and an indicator identifying when the interface link is to change operation based on the second mapping configuration.

18. The method of claim 17, wherein the indicator is a specific frame number used to identify the second data frame of the plurality of data frames.
