Abstract: An apparatus includes a beam selection hardware accelerator for determining a set of beams to be used for data scheduling by a wireless node for a transmission time interval, the beam selection hardware accelerator being configured to: receive a beam information and information indicating an angular separation of beams for a set of selected beams; create a graph based on the beam information and the minimum angular separation; select a set of beams, out of a plurality of beams, as a maximum weight independent set of beams based on the created graph; and provide a notification of the selected set of beams.

Abstract: An apparatus is disclosed, comprising means for identifying a plurality of user equipment (UE), each transmitting one or more uplink packets for decoding at a base station associated with a given cell of a radio network. The apparatus further comprises means for clustering the identified user equipment into joint processing groups, each joint processing group comprising the identities of two or more user equipment as clustered and means for performing, in a first processing stage, joint processing of the uplink data streams for identified user equipment within common joint processing groups using one or more first processing algorithms to produce corresponding first processed uplink data streams. The apparatus further discloses means for performing one or more subsequent processing stages on the first processed uplink data streams, subsequent to the joint processing, to produce decoded uplink data streams, the one or more subsequent processing stages using one or more second processing algorithms, different from the first processing algorithm.

Abstract: Systems, methods, apparatuses, and computer program products relating to coordinated scheduling with adaptive muting are provided. One method comprises transmitting, by a network element, calculated impact information for a cell of the network element when taking an action related to a cell of the network element and/or taking an action related to a cell of a second network element. The method may also comprise transmitting a request for taking the action related to the cell of the second network element under certain circumstances.

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 translation: 第一小区确定UE应该跳过HARQ周期，其中每个UE要参与CoMP传输。 要执行跳过以使得第一小区能够通过用于HARQ传输的回程链路从第二小区接收信息。 为了从UE接收在第一小区的传输，调度并参与UE的第一HARQ周期。 通过在从上行链路CoMP传输解码信息之前发送对UE的确认，并且不为UE调度用于PDCCH的许可的PDCCH许可来发送对HARQ的HARQ周期， HARQ周期。 跳过取决于以下中的一个或多个：回程延迟，第一小区中的负载，UE的类型或对第二小区的请求。 还公开了装置和程序产品。
