Burst avoidance in uplink systems

摘要

A method in a base station, and a base station, adapted for scheduling and receiving uplink transmissions from user entities and further forwarding data related to such transmissions to a core network, wherein the base station being adapted for transmitting serving grant signals for allowing a user entity to transmit uplink transmissions at a given maximum granted data rate, at least at a subsequent transmission opportunity. An uplink transmission from a user entity may be responded to by the base station by a not-acknowledge, NACK, or an acknowledge, ACK, signal. The method comprises the steps of: detecting the rate of an uplink transmission; detecting whether an overload situation exists, and if the rate exceeds the granted rate and an overload situation exists, sending an ACK to the user entity without forwarding any uplink data to the core network.

1. A method in a base station that is adapted for: (i) scheduling and receiving uplink transmissions from user entities, (ii) forwarding data related to such transmissions to a core network, and (iii) transmitting serving grant signals for allowing a user entity to transmit uplink transmissions at a given maximum granted data rate, at least at a subsequent transmission opportunity, wherein the base station may respond to an uplink transmission from a user entity by a not-acknowledge (NACK) signal or an acknowledge (ACK) signal, the method comprising:
detecting the rate of an uplink transmission; detecting whether an overload situation exists; detecting whether the rate of the uplink transmission exceeds a granted rate; and if the rate exceeds the granted rate and an overload situation exists, sending an ACK to the user entity without forwarding to the core network any uplink data from the uplink transmission.
