Abstract:
1. A cellular communication system, comprising: a macro base station that operates in accordance with a cellular protocol; and at least one mobile relay in communication with the macro base station and a plurality of user equipments (UEs), wherein the at least one mobile relay transmits uplink (UL) quality of service (QoS) status to the macro base station, the UL QoS status corresponding to a first set of UEs that receive UL QoS below a predetermined level, wherein for each UE of the first set of UEs, a count of UL QoS requests received from the UE by the at least one mobile relay is greater than a first predetermined value and a served-to-requested ratio that is a ratio of a count of bytes of UL data served to the UE by the at least one mobile relay to a count of bytes of UL data requested by the UE from the at least one mobile relay is less than a second predetermined value, wherein the UL QoS status is transmitted as a buffer status packet that indicates occupancy of one or more buffers of the first set of UEs, wherein the cellular protocol includes at least one of High Speed Packet Access+ (HSPA+) cellular protocol and Long Term Evolution (LTE) cellular protocol, wherein for the HSPA+ cellular protocol, the buffer status packet includes a predetermined bit count that indicates a count of bytes stored in the one or more buffers of the first set of UEs that have a happy bit set to unhappy status, and wherein for the LTE cellular protocol, the buffer status packet includes a predetermined count of bits that indicates a count of bytes stored in the one or more buffers of the first set of UEs.
