Abstract: A method for power control for uplink transmission is provided. In an embodiment, a method in a user equipment (UE) for reference signal (RS) relationship specific uplink (UL) transmission power control includes transmitting, by the UE, a first UL signal according to a first power control set including at least one of a first target power, a second target power, a DL reference signal (RS) for pathloss estimation, a pathloss compensation factor, and a transmit power command (TPC). The first power control set is determined according to a first RS relationship between one first RS and a first UL signal.

Abstract: A New Radio (NR) control signal that indicates one or more Long Term Evolution (LTE) network parameters may be transmitted to NR UEs to enable the NR UEs to identify which resources carry LTE signal(s). The NR UEs may then receive one or more NR downlink signals over remaining resources in a set of resources without processing those resources that carry LTE signal(s). The NR downlink signals may have a zero power level, or otherwise be blanked, over resources that carry the LTE signal(s).

Abstract: System and method embodiments are provided to support network communications with groups of UEs. The embodiments include a two-level group-based hybrid-automatic repeat request (HARQ) mechanism and acknowledgement (ACK)/negative ACK (NACK) feedback. An embodiment method includes receiving, at a UE within a virtual multi-point (ViMP) comprising UEs, a data packet for a target UE (TUE) that is broadcasted from a base station (BS) to the ViMP node, decode the data packet, and upon successfully decoding the data packet, broadcasting the data packet to the UEs within the ViMP node until a timer pre-established by the BS expires or an ACK message is received from the TUE or the ViMP node. In an embodiment, broadcasted data received in the ViMP node is re-broadcasted upon receiving a negative acknowledgement (NACK) message from the TUE, a beacon UE, or any of the UEs within the ViMP node.

Abstract: Approaches for provisioning and communicating physical signals and/or channels in NR networks are disclosed. Operations include transmitting from, or receiving at, or transmitting to, or receiving from, a transmit and receive point of an NR Cell, a physical signal and/or channel based on a user equipment (UE) specific parameter assigned via another NR Cell, and transmitting from, or receiving at, or transmitting to, or receiving from, the transmit and receive point another signal and/or channel wherein the other signal and/or channel is based on a UE specific parameter assigned via the NR Cell. A transmit and receive point and a UE for implementing the operations are also disclosed. The UE specific parameters can belong to different UE ID groups, where one of the groups is associated with mobile UEs. Approaches for allocating, assigning and monitoring for UE specific parameters are also disclosed.
