Abstract: A base station may transmit downlink control information (DCI) scheduling communications between the base station and a UE. The DCI is in a fallback DCI format. Based on whether or not the DCI is in a UE specific search space with cyclic redundancy check (CRC) scrambled by a UE ID of the UE, data transmitted by the base station or by the UE according to the DCI may be scrambled by a sequence that is initialized with a configurable parameter, or initialized with a cell ID.

Abstract: A method embodiment includes receiving, by a first network device, a first transmission comprising an explicit first source identification (ID). The first source ID is added to a list of active source IDs. The first network device receives a second transmission. The second transmission does not include an explicit second source ID. The first network device determines the second source ID by using the list of active source IDs.

Abstract: Systems and methods are provided that allow a transmit receive point (TRP) that is a member of a group of TRPs to convey a characteristic of the group through the transmission of a synchronization sequence. A transmit receive point in a first group of TRPs transmits with a first synchronization sequence. A TRP in a second group of TRPs transmits with a second synchronization sequence, the first and second synchronization sequences being different from each other. The TRPs of the first group share a common first characteristic and the TRPs of the second group share a common second characteristic. The transmission of the first synchronization sequence conveys the first common characteristic, and the transmission of the second synchronization sequence conveys the second common characteristic.

Abstract: An embodiment method includes identifying a plurality of VTP configurations representing allocations of TPs among a plurality of VTPs each having at least one TP. Potential serving VTPs are then identified for a selected UE in a plurality of UEs according to at least one UE centric criterion. The potential serving VTPs are selected for each of the plurality of VTP configurations. A UE measurement set is then scheduled for the potential serving VTPs for a scheduled channel resource according to measurement parameters. The method further includes selecting a serving VTP configuration from the plurality of VTP configurations according to UE measurement feedback from the selected UE.

Abstract: A method for wireless communications includes receiving signaling for indicating a time division duplexing (TDD) frame structure configuration from a base station. The TDD frame structure configuration corresponds to a time duration of 0.1 ms, 0.125 ms, 0.2 ms, 0.25 ms, 0.5 ms, or 1.0 ms, the TDD frame structure configuration including two switching points between downlink transmissions and uplink transmissions. The method further includes communicating downlink and uplink transmissions according to the TDD frame structure configuration. The TDD frame structure configuration may further include a guard period for separating the first downlink transmission and the first uplink transmission in the time domain.

Abstract: A method for operating a centralized controller in a communications network with a plurality of transmission points includes generating a plurality of overlays for the communications network in accordance with first mutual intercell interference levels for transmission point pairs in the communications network, wherein each overlay of the plurality of overlays comprises virtual transmission points, and selecting a first overlay of the plurality of overlays in accordance with a merit measure derived from first user equipments (UEs) operating in the communications network tentatively scheduled to each overlay of the plurality of overlays. The method also includes scheduling a first subset of the first UEs operating in the communications network during a first resource unit in accordance with the selected first overlay.

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: Systems, methods, and apparatuses for providing waveform adaptation are provided. In an example, a method is provided for identifying a plurality of candidate waveforms, and selecting one of the candidate waveforms for data transmission. The candidate waveforms may be identified in accordance with one or more criteria, such as a transmission capability of the transmitting device, a reception capability of the receiving device, a desired Peak-to-Average-Power-Ratio (PAPR) characteristic, adjacent channel interference (ACI) rejection requirements, spectrum localization requirements, and other criteria. The waveform selected for data transmission may be selected in accordance with one or more waveform selection criteria, such as traffic characteristic, application types, etc.
