Abstract: Embodiments are provided to serve user equipments (UEs) that experience, for example persistently, inter-transmission point group (TPG) interference in a wireless or cellular network. The embodiments include steps to serve edge UEs (EUs) such as persistent EUs (PEUs) using a set of transmission points (TPs) in one or more TPGs. The selected set of TPs used for serving the EUs or PEUs are dynamically determined based on a UE-centric metric. The metric involves the PEUs and surrounding UEs. The UE-centric metric is used to partition the network to multiple TPG sets. For each one of multiple assigned resource units (RUs), a TPG set that maximizes or improves a network-wide utility is used for scheduling transmissions. Further, for each RU, the UEs are associated with an optimized or improved TPG in the used TPG set.

Abstract: A user equipment (UE) may determine that a transmission resource includes a first orthogonal frequency-division multiplexing (OFDM) symbol that is configured as a downlink symbol or as flexible, where the transmission resource is allocated for uplink (UL) transmissions during a time duration, and includes K transmission occasions (TOs). The UE may transmit a first UL transmission in the transmission resource omitting the first OFDM symbol. The first UL transmission includes K repetitions to be transmitted in the respective K TOs, and the K repetitions includes an initial transmission and at least one retransmission of the initial transmission.

Abstract: A method includes receiving a first assignment for a first transmission with a first hybrid automatic repeat request (HARQ) process identifier (process ID) in a first network resource, receiving a second assignment for a second transmission with a second HARQ process ID in a second network resource, wherein the first network resource and the second network resource differ in a domain other than a time domain, detecting an indication indicating that the first HARQ process ID and the second HARQ process ID map to a same transmission block (TB), and communicating with an access node, a transmission associated with at least one of the first HARQ process ID or the second HARQ process ID.

Abstract: Embodiments are provided for interference avoidance based on signal alignment for multiple-input and multiple-output (MIMO) with orthogonal frequency-division multiplexing (OFDM) or OFDM access (OFDMA). The embodiments include a signal alignment scheme using both spatial and frequency dimensions. The scheme includes an existing link between an existing transmitter and an existing receiver, and a new link between a new transmitter and a new receiver. The new transmitter determines combinations of space dimensions and frequency dimensions unused in transmission on an existing link, and assigns signals for transmission on the new link at one or more of the unused combinations of space dimensions and frequency dimensions. The existing receiver is further configured to reallocate its power to release, using a greedy search algorithm, a small eigenvalue algorithm, or a best throughput algorithm, a null space of some space dimensions to the new transmitter.

Abstract: Soft information for achieving interference cancellation in downlink transmissions can be communicated over device-to-device (D2D) links, thereby allowing paired user equipments (UEs) to receive downlink transmissions over the same radio resources. More specifically, paired UEs that receive transmissions over the same time-frequency resources may exchange soft or hard information over D2D links in order to facilitate interference cancellation. The D2D links may be unidirectional or bidirectional, and may be established over in-band or out-of-band resources. Paired UEs may be in the same or different cells, and may receive their respective transmissions from the same or different transmit point. UEs may be paired with one another based on various criteria, e.g., interference cancellation capabilities, scheduling metrics, etc.

Abstract: Virtualized group-wise communications between a wireless network and a plurality of user equipments (UEs) are supported using UE cooperation. UE cooperation includes receiving, at a cooperating UE (CUE), downlink information from the wireless network destined for a target UE (TUE) and associated with a group identifier (ID). The group ID indicates a virtual multi-point (ViMP) node that includes the TUE and the CUE. The UE cooperation also includes sending the downlink information to the TUE. The UE or UE component can have a processor configured to forward between the wireless network and a TUE at least some information that is associated with a group ID indicating a ViMP node that groups the TUE and the UE.
