    Abstract: A telecommunication network may operate to enable a wake up signals (WUSs) within the telecommunication network. A mobility management entity (MME) may estimate a coverage enhancement (CE) level of a user equipment (UE), determine, based on the CE level, a number of repetitions for a wake up signal (WUS) for the UE, and cause a WUS for UE to be transmitted to a radio access network (RAN) node corresponding to the UE. The RAN node may inform the MME that the RAN node has disabled the WUS feature, and may cause system information to be broadcast to UEs in IDLE mode, indicating that the WUS feature of the RAN node has been disabled. A UE may determine a paging occasion (PO) determine a maximum WUS duration, minimum offset, and start location of the WUS.

    Abstract: Systems and methods of early termination of uplink data transmissions for a UE are described. The UE transmits capacity information that indicates that the UE supports use of an ETS. The ETS indicates successful reception by the eNB of the uplink data prior to an end of a scheduled transmission period to transmit repeated instances of the data. The UE receives a schedule for repeated transmissions of the data that is based on a coverage level of the UE, and then transmits sets of one or more repetitions. After the transmission, the UE monitors a predetermined resource whether the ETS is present or whether the ETS indicates an ACK. If the ETS indicates successful reception, the UE terminates transmission of the remaining repetitions of the data and enters a sleep mode or transmits other uplink data.

    Abstract: Technology for a user equipment (UE), configured for coverage enhanced (CE) machine type communication (MTC) is disclosed. The UE can encode, at the UE, a UE capability message for transmission to a next generation node B (gNB) or evolved Node B (eNB), wherein the UE capability message includes a capability to support communication using a modulation and coding scheme (MCS) that includes 64 quadrature amplitude modulation (QAM). The UE can decode, at the UE, a higher layer signaling message to configure the UE to operate in a CE mode A. The UE can decode, at the UE, data received in a physical downlink shared channel (PDSCH) transmission to the UE that is modulated using a 64 QAM.

    Abstract: Techniques for channel state information (CSI) reporting are discussed. One example apparatus at a user equipment can derive, for one or more subframes of a license assisted access (LAA) secondary cell (SCell), one or more channel measurements based on reference signals (e.g., cell-specific reference signals (CRS) or CSI reference signals (CSI-RS)), in those subframes; generate CSI that comprises a channel quality indicator (CQI) based on an average of the one or more channel measurements from multiple subframes comprising a first subframe and a later second subframe, wherein each orthogonal frequency division multiplexing (OFDM) symbol of a second slot of the first subframe is occupied, wherein each of a first three OFDM symbols of the second subframe are occupied, and wherein each OFDM symbol between the first subframe and the second subframe is occupied; and generate a CSI report that indicates the set of CSI parameters.

    Abstract: An apparatus for use in an eNB, the apparatus includes circuitry to generate an assignment of one or more interlaces to a UE within a cell managed by the eNB, where the one or more interlaces are selected from a total number of interlaces, and an interlace of the total number of interlaces may include multiple resource blocks spanning within a system bandwidth. The circuitry included in the apparatus is further to encode the assignment by a bit string including one or more bits, which may be a bitmap or an encoding bit string. The circuitry included in the apparatus is further to transmit the bit string to the UE. Other embodiments may also be described and claimed.

    Abstract: Methods, systems, apparatus, and computer programs, for activating cross-slot scheduling in user equipment (UE) to achieve power savings. In one aspect, the method can include actions of generating, by an access node, an RRC communication including one or more parameters that, when processed by the UE, configures the UE to forego use of computing resources to buffer for potential PDSCH transmission for a predetermined amount of time, encoding, by the access node, the RRC communication for transmission to the UE, and causing, by the access node, one or more antennae to transmit the encoded RRC communication to the UE.
