Abstract:
1. A method for performing long term evolution (LTE) hybrid automatic rapid request (HARQ) processing, the method comprising: at an LTE multi-UE simulator distinct from an evolved node B and user equipment, the LTE multi-UE simulator configured to simulate a plurality of user devices: receiving, from the evolved node B and by the LTE multi-UE simulator, downlink control channel data for the plurality of user devices being simulated, wherein the downlink control channel data includes HARQ data; decoding, by the LTE multi-UE simulator, the HARQ data for each user device of the plurality of user devices, wherein the HARQ data indicates at least one negative acknowledgement (NACK) associated with a first user device of the plurality of user devices and at least one acknowledgement (ACK) associated with a second user device of the plurality of user devices, wherein decoding HARQ data for each user device of the plurality of user devices includes decoding physical HARQ indicator channel (PHICH) information and determining, using the decoded PHICH information, that data associated with an LTE user device is to be retransmitted and wherein decoding physical HARQ indicator channel (PHICH) data includes determining probability metrics for indicating priority among data to be retransmitted; performing, by the LTE multi-UE simulator, at least one HARQ data verification step for each user device of the plurality of user devices; and acting, by the LTE multi-UE simulator, on the verified HARQ data for each user device of the plurality of user devices.
