Patent ID: 8374621

Claim:
A method for reducing the likelihood of deadlock in a wireless communication system, comprising: determining that user equipment has data to transmit, wherein the data corresponds to a scheduled flow, and wherein the scheduled flow comprises a flow other than a non-scheduled flow that is delay sensitive; determining that a scheduled grant corresponding to the scheduled flow is insufficient to transmit at least one protocol data unit (PDU), wherein the scheduled grant comprises a dynamic resource allocation to the scheduled flow, and wherein the determining that the scheduled grant corresponding to the scheduled flow is insufficient comprises comparing a fixed size of the at least one PDU with the scheduled grant; and transmitting an insufficiency indicator, in response to determining that the scheduled grant is insufficient to transmit at least one protocol data unit, to a scheduler at least once to reduce the likelihood of deadlock, wherein the at least once transmitted insufficiency indicator comprises an indication that the scheduled grant is insufficient to transmit at least one protocol data unit.
