Abstract: Embodiments of efeMTC synchronization signals for enhanced cell search and enhanced system information acquisition are described. In some embodiments, an apparatus of a base station (BS) is configured to generate a length-x sequence for an efeMTC synchronization signal, the length-x sequence configured for repetition in frequency domain within 6 physical resource blocks (PRB). In some embodiments, to generate the length-x sequence, the BS may be configured to select any one index of the set of root indices {1, 2, 63}, excluding the root indices 25, 29 and 34, to correspond to a different physical-layer cell identity (PCID). In some embodiments, the BS may be configured to encode RRC signaling to include a System Information Block (SIB) comprising configuration information for transmission of the efeMTC synchronization signal, and transmit the length-x sequence as the efeMTC synchronization signal in frequency resources according to the SIB.

Abstract: A method of support of aggressive user equipment (UE) minimum processing times for physical downlink shared channel (PDSCH) processing and physical uplink shared channel (PUSCH) preparation in new radio (NR) is disclosed. The method includes indicating or causing to indicate a capability from the UE to the network in the form of capability reporting for support of Capability 2 processing times, and multiplexing or causing to multiplex scheduling instances with Capabilities 1 or 2 based on the indication. The method also includes applying or causing to apply a relaxation to the minimum UE processing times, N1, indicating time between end of PDSCH to earliest start of corresponding hybrid automatic repeat request-acknowledge (HARQ-ACK) feedback transmission when the PDSCH has specific durations and/or mapping types or has time-domain overlaps with the scheduling physical downlink control channel (PDCCH). A corresponding apparatus and non-transitory computer readable medium are also disclosed.

Abstract: Embodiments of a User Equipment (UE), generation Node-B (gNB) and methods of communication are generally described herein. The UE may receive, from a gNB, a narrowband physical downlink control channel (NPDCCH) that indicates a number of narrowband internet-of-things (NB-IoT) downlink subframes for a downlink scheduling delay of a narrowband physical downlink shared channel (NPDSCH) in one or more radio frames configured for time-division duplexing (TDD) operation. Subframes of the one or more radio frames may include uplink subframes, NB-IoT downlink subframes for downlink NB-IoT transmissions, and downlink subframes for other downlink transmissions. The UE may determine the downlink scheduling delay based on an earliest subframe for which a count of NB-IoT downlink subframes is equal to the number of NB-IoT downlink subframes indicated in the NPDCCH.

Abstract: An apparatus configured to be employed in a gNodeB associated with a new radio (NR) communication system that support resource sharing between NR physical downlink shared channel (PDSCH) and NR physical downlink control channel (PDCCH) is disclosed. The apparatus comprises a processing circuit configured to generate a PDSCH dynamic rate matching resource set configuration signal comprising information on one or more overlap resource sets, wherein each the one or more overlap resource sets comprises time-frequency resources on which any overlapping PDSCH may or may not be mapped, based on an indication provided within a PDSCH rate matching indicator signal. The apparatus further comprises a radio frequency (RF) interface, configured to provide the generated PDSCH dynamic rate matching resource set configuration signal, to an RF circuitry, in order to subsequently provide the PDSCH dynamic rate matching resource set configuration signal to a user equipment (UE), in order to enable the UE to identify the one or more overlap resource sets.

Abstract: Embodiments of a User Equipment (UE), generation Node-B (gNB) and methods of communication are generally described herein. The UE may receive a narrowband physical downlink control channel (NPDCCH) that includes an uplink scheduling parameter. The UE may determine an uplink scheduling delay for transmission of a narrowband physical uplink shared channel (NPUSCH) in accordance with time-division duplexing (TDD). The uplink scheduling delay may be based on a sum of a predetermined first number of subframes and a variable second number of subframes. The second number of subframes may be based on a window of variable size that starts when the first number of subframes has elapsed since reception of the NPDCCH, and ends when a number of uplink subframes has elapsed since the start of the window. The number of uplink subframes may be indicated by the uplink scheduling parameter.

Abstract: Systems, methods, and circuitries are disclosed for determining Precoding Resource Block Groups (PRGs). In one example, a processor of a base station (BS) is configured to determine a plurality of PRGs that includes a number N consecutive Physical Resource Blocks (PRBs) over which a same precoder assignment is used, starting from a reference PRB. The plurality PRGs include a first boundary PRG, a second boundary PRG, and one or more other PRGs. The first boundary PRG is located at an upper boundary of a bandwidth part. The first boundary PRG comprises fewer than N PRBs when the upper boundary of the bandwidth part is not aligned with a PRG boundary. The second boundary PRG comprises fewer than N PRBs when a lower boundary of the bandwidth part is not aligned with a PRG boundary. A downlink data channel is transmitted to a UE in accordance with the precoder assignments.

Abstract: User equipment (UE) includes processing circuitry, where to configure the UE for New Radio (NR) communications in an unlicensed spectrum, the processing circuitry is to decode a first configuration message received from a base station, the first configuration message including a channel quality indicator (CQI) table indication identifying a CQI table. A second configuration message is decoded, the second configuration message received separately from the first configuration message and including a modulation and coding scheme (MCS) table indication identifying an MCS table. DCI received via a PDCCH is decoded, the DCI providing a DL grant and an MCS index in the MCS table. DL information received via a PDSCH is decoded using modulation order and target code rate corresponding to the MCS index in the MCS table.
