Abstract: A user equipment (UE) is configured to perform cell selection and camp on a first cell in a first frequency resource. The UE is configured to determine that proximity services are supported in a second frequency resource. The first and second wireless frequency resources are within licensed spectrums corresponding to one or more mobile communications networks. The UE is configured to start device-to-device communication on the second frequency resource and send, with the transceiver, a device-to-device message in the second frequency resource. The device-to-device message includes one of a device-to-device discovery message and a device-to-device communication message.

Abstract: Technology for a user equipment (UE) operable to perform adaptive time division duplexing (TDD) hybrid automatic repeat request (HARQ)-ACKnowledgement (ACK) reporting is described. The UE can implement an adaptive uplink-downlink (UL-DL) configuration received from an eNodeB. The UE can decode a downlink (DL) HARQ reference configuration received from the base station for a serving cell, wherein the DL HARQ reference configuration is for the implemented adaptive UL-DL configuration. The UE can decode a reference UL-DL configuration received from the base station via a system information block (SIB). The UE can encode HARQ-ACK feedback for transmission on an uplink channel of the serving cell in accordance with the DL HARQ reference configuration. The UE can perform uplink scheduling and the HARQ-ACK feedback based on the reference UL-DL configuration received from the base station via the SIB.

Abstract: User equipment (UE) can include processing circuitry configured to decode radio resource control (RRC) signaling from a base station, the RRC signaling indicating a transmission coding scheme for a physical uplink shared channel (PUSCH) transmission. PUSCH-to-phase tracking reference signal (PT-RS) energy per resource element (EPRE) ratio is determined using the RRC signaling. A PT-RS power boosting factor is determined based on the transmission coding scheme and the PUSCH-to-PT-RS EPRE ratio. The PT-RS is encoded for transmission using a plurality of PT-RS symbols, the transmission to using increased transmission power corresponding to the PT-RS power boosting factor. The RRC signaling further includes a flag enabling the PT-RS transmission. The PUSCH-to-PT-RS EPRE ratio is 00 or 01, and the transmission coding scheme is a codebook-based uplink transmission or non-codebook-based uplink transmission.

Abstract: Methods, apparatuses, and systems are disclosed for determining prioritization of subsequent small data transmissions (SDTs) and measurement occasions for a UE in inactive mode. The UE may determine that one or more subsequent SDT occasions of an SDT session conflict in time with one or more measurement occasions scheduled during the SDT session. In response, the UE may determine which of the subsequent SDT occasions to utilize or forgo, and which of the measurement occasions to utilize or forgo. The procedure for making such determinations may vary based on the type of measurement occasion involved in the conflict. For example, the procedure may vary based on whether the measurement event pertains to inter-frequency neighbor cell measurement occasions, inter-RAT neighbor cell measurement occasions, intra-frequency neighbor cell measurement occasions, serving cell downlink measurement occasions, and/or serving cell paging occasions.

Abstract: This disclosure relates to techniques for improving capability signaling and performing search space set switching, particularly with large sub-carrier spacings, as in high frequency ranges. In various scenarios, a user equipment (UE) device may signal its capability to perform multi-slot PDCCH monitoring and/or single-slot PDCCH monitoring, e.g., at various sub-carrier spacings, for various PDCCH/DCI types, etc. Various technical difficulties in this area are addressed, including increasing flexibility and versatility in capability signaling, overbooking, signaling and timing of search space set switching, and beam sweeping transmission of DCI Format 2_0, among others.

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.

Abstract: Systems, methods, and circuitries are disclosed for avoiding slot decoding failure due to beam switching of a common beam. In one example, a baseband processor for a user equipment (UE) is configured to cause the UE to perform various operations. The operations include receiving a data transmission on a plurality of component carriers (CCs) carrying corresponding symbols on a common beam; receiving a beam switch command from the network node, wherein the beam switch command is configured to cause the UE to switch a receiving (RX) beam at an end boundary of a first symbol of the data transmission; identifying one or more symbols for restricted scheduling in one or more CCs of the plurality of CCs based on the beam switching on the first symbol; and ignoring the one or more symbols identified for restricted scheduling for decoding of the data transmission.
