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:

providing, at a radio equipment control (REC) device and at a radio equipment (RC) device, a first mapping configuration for data streaming over a communication link between the REC and RE devices, wherein the first mapping configuration indicates a first bandwidth for each antenna carrier of a set of antenna carriers of the RE device;

streaming data frames over the communication link in accordance with the first mapping configuration;

providing, at the REC and RE devices, a second mapping configuration for data streaming over the communication link, wherein the second mapping configuration indicates a second bandwidth for each antenna carrier, at least one second bandwidth for a particular antenna carrier being different from a first bandwidth for the particular antenna carrier;

configuring a shadow register of the REC device based on the second mapping configuration;

configuring a shadow register of the RE device based on the second mapping configuration;

providing, at the REC and RE devices, an indication identifying when the communication link is to change operation from the first mapping configuration to the second mapping configuration; and

after streaming a data frame associated with the indication in accordance with the first mapping configuration, streaming the data frames over the communication link in accordance with the second mapping configuration.

2. The method of claim 1, wherein the indicator specifies a number of data frames.

3. The method of claim 1, wherein the indicator is a specific frame number used to identify a particular data frame of the data frame.

4. The method of claim 1, further comprising:

updating a control register of the REC device with a value from the shadow register of the REC device prior to streaming the data frames over the communication link in accordance with the second mapping configuration; and

updating a control register of the RE device with a value from the shadow register of the RE device prior to streaming the data frames over the communication link in accordance with the second mapping configuration.

5. The method of claim 1, wherein the first bandwidth for each antenna carrier indicates a number of data frames allocated to each antenna carrier.

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

7. A radio equipment control system, comprising:

a radio equipment control (REC) device; and

a radio equipment (RE) device coupled to the REC device via a communication link;

wherein, the REC and RE devices are each configured to;

receive a second mapping configuration for data streaming over the communication link, wherein the second mapping configuration indicates a second bandwidth for each antenna carrier, at least one second bandwidth for a particular antenna carrier being different from a first bandwidth for the particular antenna carrier;

receive an indication identifying when the communication link is to change operation from the first mapping configuration to the second mapping configuration;

determine that a data frame associated with the indication has been streamed via the communication link; and

after determining that the data frame has been streamed, operate in accordance with the second mapping configuration to stream data over the communication link; and

wherein, after providing the second mapping configuration at the REC and RE devices;

the REC device further configures a shadow register of the REC device based on the second mapping configuration; and

the RE device further configures a shadow register of the RE device based on the second mapping configuration.
