Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] Such as figure 1 As shown, the embodiment of the present invention provides a remote radio unit, including:

[0022] The processing unit 11 is configured to receive downlink data and send it to the next-level remote radio unit after processing, or to receive uplink data and send it to the upper-level remote radio unit or baseband processing unit after processing;

[0023] The forwarding part 12 is connected to the processing part 11, and is used to send the downlink data to the remote radio unit of the next level when the processing part stops working, or to send the uplink data to the radio remote unit of the next level unit or baseband processing unit to send.

[0024] In the remote radio unit provided by...

Abstract

The invention discloses a remote radio unit and a working method thereof, and relates to the technical field of communications, wherein the problem in the prior art that cascaded radio remote units are easily influenced by the fault of each single radio remote unit so as to reduce the link communication efficiency can be solved. The remote radio unit comprises a processing part used for receiving downlink data and sending the data to a lower-level radio remote unit after processing the data, or receiving uplink data and sending the data to an upper-level radio remote unit/baseband processing unit after processing the data; and a forwarding part connected with the processing part and used for sending the downlink data to the lower-level radio remote unit or sending the uplink data to the upper-level radio remote unit/baseband processing unit after the processing part stops running.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a remote radio unit and a working method thereof. Background technique [0002] There are many networking modes for BBU (Building Base band Unit, baseband processing unit) and RRU (Radio Remote Unit, radio frequency remote unit), among which the commonly used configuration mode is cascade networking mode, including chain networking mode and Ring networking mode, etc. For these networking modes, whether the state of the M-th level RRU (M-1 RRUs are separated from the BBU) is normal or not directly determines the status of the M+1 level (the next-level RRU of the M-th level RRU) , and there is uplink and downlink data exchange with the M-th level RRU) whether the data or voice service of the RRU is normally accessed (also referred to as normal operation). [0003] At present, the M-level RRU requires the BBU to reset the RRU through signaling or the RRU self-resets due to th...
