Redundant transmission of real time data

An edge node comprising:

• a transceiver configured to send wireless signals to and receive wireless signals from a second edge node in a wireless network;
• and
• processing circuitry coupled with the transceiver, wherein the processing circuitry is configured to cause the edge node to at least:
• send a first real-time transport protocol (RTP) packet to the second edge node, wherein the first RTP packet comprises a first real time data frame;
• determine that a radio link condition is sufficient to support redundant transmission of real time data to the second edge node, wherein the radio link condition is sufficient when radio resource allocation allows bundling together two or more real time data frames in a single transport block;
• and
• in response to determining that the radio link condition is sufficient to support redundant transmission of real time data:
• bundle the previously sent first real time data frame with a next sequential real time data frame in a second RTP packet at a packet data convergence protocol (PDCP) layer of the edge node, wherein the next sequential real time data frame has not been previously sent to the second edge node;
• and
• send the second RTP packet comprising redundant transmission of the first real time data frame to the second edge node.

A non-transitory computer readable storage medium having computer program code stored thereon, the computer program code comprising program code, which, when executed by one or more processors implemented on an edge node in a wireless network, is configured to cause the edge node to perform a method comprising:

• sending a first real-time transport protocol (RTP) packet to a second edge node, wherein the first RTP packet comprises a first real time data frame;
• determining that a radio link condition is sufficient to support redundant transmission of real time data to the second edge node, wherein the radio link condition is sufficient when radio resource allocation allows bundling together two or more real time data frames in a single transport block;
• and
• in response to determining that the radio link condition is sufficient to support redundant transmission of real time data:
• bundling the previously sent first real time data frame with a next sequential real time data frame in a second RTP packet at a packet data convergence protocol (PDCP) layer of the edge node, wherein the next sequential real time data frame has not been previously sent to the second edge node;
• and
• sending the second RTP packet comprising redundant transmission of the first real time data frame to the second edge node.
