Dynamic selection of a donor base station to serve a relay node

A wireless communication system comprising:

• a relay node (RN) operable to serve user equipment devices (UEs);
• a base station system (BSS) that includes a plurality of base stations each operable to serve UEs and operable to serve the RN, wherein each base station is configured to provide service on at least one carrier;
• and
• a controller configured to cause the wireless communication system to perform operations comprising:
• determining a type of content communicated between the BSS and UEs served by the BSS (BSS-served content type);
• determining a type of content communicated between the RN and UEs served by the RN (RN-served content type);
• based on both the determined BSS-served content type and the determined RN-served content type, selecting one of the plurality of base stations to serve the RN;
• and
• causing the selected base station to serve the RN.

A non-transitory computer readable medium having stored thereon instructions executable by a processor to cause a wireless communication system to perform operations, the wireless communication system including a base station system (BSS), wherein the base station system (BSS) comprises a plurality of base stations each operable to serve user equipment devices (UEs) and operable to serve a relay node (RN), wherein the RN is in turn operable to serve UEs, and wherein each base station is configured to provide service on at least one carrier, the operations comprising:

• determining a type of content communicated between the BSS and UEs served by the BSS (BSS-served content type);
• determining a type of content communicated between the RN and UEs served by the RN (RN-served content type);
• based on both the determined BSS-served content type and the determined RN-served content type, selecting one of the plurality of base stations to serve the RN;
• and
• causing the selected base station to serve the RN.
