    Abstract: Systems, methods, apparatuses, and computer program products for physical broadcast channel extension are provided. For example, a method can include mapping, by the network element, symbols of a physical channel to a first set of resource elements. The method can also include identifying, by the network element, a portion of the symbols of the physical channel mapped outside a second set of resource elements. The second set of resource elements can be a subset of the first set of resource elements, The method can further include preparing, by the network element, replacement symbols corresponding to a first portion of the physical channel outside the second set of resource elements. The method can additionally include mapping, by the network element, the replacement symbols to the second set of resource elements in extension symbols. The method can also include transmitting, by the network element, the physical channel and the extension symbols.

    Abstract: Systems, methods, apparatuses, and computer program products for intelligent reflecting surface configuration. The method may include scanning for synchronization signal blocks and reflection surface synchronization signal blocks during a cell search at a frequency on a synchronization raster. The method may also include determining whether a synchronization signal block or a reflection surface synchronization signal block is detected as a result of the scanning. The method may further include selecting a detected synchronization signal block or a detected reflection synchronization signal block based on a measurement metric of the detected synchronization signal block and the detected reflection synchronization signal block. In addition, the method may include performing an access procedure with a network element using the selected synchronization signal block or the selected reflection synchronization signal block.

    Abstract: Techniques of defining a transmission scheme for NB-IoT data include determining the TBS based on 16-quadrature amplitude modulation (QAM) analysis but use quadrature phase-shift keying (QPSK) for modulation. For example, a base station (eNB) may determine that a UE is configured to receive or transmit data with 16-QAM modulation via capability signalling from the UE. Upon performing this determination, the eNB transmits configuration data to the UE, e.g., via DCI, configuring the UE to receive data over a narrowband physical downlink shared channel (NPDSCH) using 16-QAM modulation. Part of the configuration data indicates whether the UE is to support 16-QAM modulation with or without repetition via radio resource control (RRC) parameter modulation-restriction-Repetitions. Depending upon this indication, the UE may use quadrature phase-shift keying (QPSK) rather than 16-QAM despite selecting or being assigned a TBS based on 16-QAM modulation.

    Abstract: A method, an apparatus, and a computer program product to support sub-PRB allocation on the Physical Uplink Shared Channel in a wireless communications system, a new resource allocation method is described, where available physical resource blocks (PRBs) in each subframe or narrowband are reorganized into a number of sub-PRBs, which would apply to user equipment in both in CE Mode A and CE Mode B while also supporting sub-PRB allocation in Msg3 as part of early data transmission during random access, so that a user equipment, which is previously configured for using physical uplink shared channel sub-PRB resources, upon receiving an indication, will then use or determine whether to use a sub-PRB resource allocation based on the received indication.

    Abstract: A method is provided including receiving, by a user equipment, a signal either before or during a paging occasion comprising an indication indicating whether the user equipment is to skip decoding of at least one subsequent channel of a plurality of subsequent channels associated with a paging message. The plurality of subsequent channels include: a first channel carrying downlink control information for the paging message, and a second channel carrying the paging message. In response to the indication indicating that the user equipment is to skip decoding of the at least one subsequent channel, skipping decoding of the at least one subsequent channel.

    Abstract: Methods, apparatuses, and computer program products are disclosed for contention based shared preconfigured uplink resource configuration. An example method includes receiving an assignment of contention based shared preconfigured uplink resources; receiving an assignment of a common radio network temporary identifier for monitoring downlink control information indicating a negative acknowledgement for contention based shared transmission, and a dedicated radio network temporary identifier for monitoring downlink control information indicating an acknowledgement of transmission of uplink data; transmitting the uplink data using a physical uplink shared channel allocated for the contention based shared preconfigured uplink resource transmission; in response to the downlink control information indicating the negative acknowledgement and uplink grants for multiple physical uplink shared channel resources, retransmitting the uplink data on a selected one of the received uplink grants; and in response to the downlink control information indicating the acknowledgment, not retransmitting the uplink data.
