Abstract: The present disclosure is directed at systems, methods and media for relieving RAN congestion in a core network. In some embodiments, RAN congestion information is reported from user equipment to a packet data gateway (PGW) through an eNodeB and a software gateway. The PGW can aggregate the RAN congestion information and periodically notify other network nodes, for example, a PCRF, about the aggregate congestion in a network. By aggregating RAN congestion information, the PGW can substantially reduce the signaling required to report RAN congestion in the core network.

Abstract: A method and system for measuring end-to-end processing delay of the RE between an input interface and a transmit port in the downlink direction and a receive port and an output interface on the uplink direction is disclosed. The method and system if for use in a radio equipment node (RE) connected to a radio equipment control node (REC). Once the downlink and uplink radio channels are activated at a predetermined carrier frequency, a chirp sine wave is added at the input interface and the receive port such that the chirp sine wave becomes mixed with the carrier frequency. Sampling of a received downlink mixed signal is done at the transmit port and of the received uplink mixed signal at the output interface. The sampled mixed signals are then cross-correlated with a reference chirped sine wave to obtain a signal phase shift which is then converted to obtain a time delay associated with the end-to-end processing delay of the RE.

Abstract: A first cell determines that UE(s) should have HARQ cycle(s) skipped, where each of the UE(s) is to take part in a CoMP transmission. Skipping is to be performed to enable the first cell to receive information from second cell(s) over backhaul link(s) for the HARQ transmission(s). A first HARQ cycle is scheduled and participated in for the UE(s) in order to receive a transmission at the first cell from the UE(s). The HARQ cycle(s) is/are skipped for the UE(s) by sending, prior to decoding information from the uplink CoMP transmissions, an acknowledgement to the UE(s) and not scheduling the UE(s) for a PDCCH grant for the HARQ cycle(s). The skipping depends on one or more of: a backhaul latency, a load in the first cell, a type of UE, or a request to the second cell(s). Apparatus and program products are also disclosed.

Abstract: Control of transitions between radio resource control, RRC, states for a wireless terminal in a radio access network is described. The radio resource control states comprise a first state and a second state. A calculation (702) is made of a prediction of an inter-arrival time, ITB, between data bursts to be handled.

The current ITB threshold is a time interval that is depending on a function of RRC state transition costs and the fractional distribution of true predictions and false predictions of a plurality of predicted ITB values in relation to recorded ITB values.

Abstract: User equipments can achieve quick channel synchronization when establishing a connection to base stations transitioning from a sleep mode to an active mode by using discovery resource signal (DRS) processing results and cell reference signal (CRS) processing results to establish channel synchronization with a CRS antenna port. More specifically, the user equipment may be notified that the CRS antenna port and DRS antenna port are quasi-co-located (QCL), and then use DRS processing results in conjunction with CRS processing results to obtain faster channel synchronization with a CRS antenna port. This may be particularly beneficial when the target BS is transitioned from a sleep mode to an active mode in order to accept a handover of the user equipment.
