    Abstract: Aspects described herein relate to interference mitigation for communication with muting via inter-cell coordination. In one example, a network entity such as a cell may identify a time or frequency resource allocated for communication with a user equipment (UE), and transmit, to a neighboring network entity, a muting message indicating that the time or frequency resource is occupied for communication. In another example, the network entity may receive, from a neighboring network entity, a muting message indicating that a time or frequency resource is occupied for communication. The network entity may further forgo scheduling of an uplink or downlink transmission to a UE on the indicated time or frequency resource. The network entity may further schedule data for uplink or downlink transmission with the UE on a different time or frequency resource.

    Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for efficiently retransmitting radio link control (RLC) protocol data units (PDUs) to one or more UEs. When a user equipment (UE) fails to receive or decode an RLC PDU transmitted by a base station, the UE may transmit a status PDU to the base station indicating that the UE failed to receive or decode the RLC PDU. The base station may receive the status PDU from the UE, and the base station may generate a repair PDU that includes redundant bits of the lost PDU (e.g., the PDU that the UE failed to receive or decode). The base station may then transmit the repair PDU to the UE, and the UE may use the redundant bits in the repair PDU (e.g., in combination with buffered PDUs) to attempt to correctly decode the lost PDU.

    Abstract: In an aspect, a slave UE and a master UE each establish an attachment to a core network of a cellular communications system. The slave UE obtains security credentials configured to encrypt and decrypt traffic between the slave UE and the core network. A D2D connection is established between the slave UE and the master UE (e.g., tethering). One or more communication functions are offloaded from the slave UE to the master UE, including at least one communication function with the core network for maintaining the attachment of the slave UE to the core network. Application-layer data is relayed to/from the slave UE over the D2D connection. In an aspect, either the slave UE or the master UE may perform encryption and decryption of control plane signaling using the slave UE's security credentials.
