Abstract: Systems, methods, apparatuses, and computer program products for utilizing uplink (UL) CoMP helper data are provided. One method includes setting, by a network node serving a user equipment, a priority for a helper data request of an uplink transmission of the user equipment. The setting may include setting the priority based on a specific history of the user equipment. The method may also include sending the helper data request to another network node and, optionally, sending the priority set for the helper data request to said another network node.

Abstract: A distributed radio access network (RAN) is provided. A selected wireless transceiver node(s) in a selected coverage cell receives a radio frequency (RF) test signal(s). The selected wireless transceiver node(s) determines an effective gain value based on a predefined characteristic of the RF test signal(s). The selected wireless transceiver node(s) communicates the effective gain value and other related parameters to a server apparatus in the distributed RAN. The server apparatus determines a common gain value for the selected wireless transceiver node(s) in the selected coverage cell based on the parameters. Accordingly, the selected wireless transceiver node(s) operates based on the common gain value.

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.
