    Abstract: Systems, methods, apparatuses, and computer program products for joint network assisted interference cancellation and suppression (NAICS) and coordinated multi-point (COMP) operation are provided. One method includes configuring, by a network node, a victim user equipment and interfering user equipment in transmission mode 10 (TM10) with multiple channel state information (CSI) processes to perform dynamic point muting. The method may further include signaling network assisted interference cancellation and suppression (NAICS) information to the victim user equipment pretending the interfering user equipment mode is transmission mode 9 (TM9) or transmission mode 8 (TM8).

    Abstract: A method for selecting a precoding matrix indicator that optimizes a retransmission is disclosed. The method comprises causing a transmission initially, with an initial rank, on two codewords, by a base station to at least one user equipment in a wireless network. When the base station receives a negative acknowledgement such that at least one codeword was not decoded successfully, then a decision is made to retransmit using a consequent rank for retransmission, wherein the consequent rank is lower than the initial rank. A precoding matrix indicator for the consequent rank retransmission is selected and a retransmission, with the consequent rank, is made to happen on the at least one codeword that was previously not successfully decoded. Apparatus, program products, and software are also disclosed.

    Abstract: A first radio access network (RAN) accesses information indicating an availability status of an interface between an access and mobility management function (AMF) in a first wireless communication system and a mobility management entity (MME) in a second wireless communication system. The first RAN receives a trigger for a handover of a user equipment between the first RAN and a second RAN. The handover is selectively performed via the interface or a redirect via a network element shared by the first and second wireless communication systems based on the availability status. In some cases, the first RAN receive the information indicating the availability status prior to providing the request for the handover and stores the information in a database associated with the first RAN, which access the information from the database.

    Abstract: Indication(s) of a configuration of first interference measurement resources in first subframe(s) and of a configuration of second interference measurement resources in second subframe(s) are received at a first BS and from a second BS using an interface between the first and second BSs. The first BS transmits zero or low power REs that coincide with the REs belonging to the first interference measurement resources in the first subframe(s). The first BS transmits full power REs that coincide with the REs belonging to the second interference measurement resources in the second subframe(s). The first interference measurement resources in the first subframe(s) are to be used by a UE (e.g., attached to the second base station) to measure interference for zero or low power REs and the second interference measurement resources in the second subframe(s) are to be used by the UE to measure interference for full power REs.
