An apparatus and system to enable URLLC PUSCH repetitions in the unlicensed spectrum are described. The number of consecutive PUSCH repetitions indicated in the RRC parameter is reinterpreted as the number of transmission occasions over which the UE is able to attempt CCA. An orphan symbol is used to provide a DMRS transmission or cyclic prefix of the PUSCH transmission causing the orphan symbol. Whether a CG-UCI is piggybacked in a PUSCH transmission, and whether DCI-DFI is used, is dependent on whether cg-RetransmissionTimer is configured.

Repetition schemes for URLLC operating in unlicensed spectrum

Systems, devices, and techniques for antenna port configuration in wireless communication systems are described. A described technique performed by a user equipment (UE) includes receiving configuration information that determines a bit-width value for an antenna port indication field of a downlink control information (DCI) format; receiving a DCI message that is in accordance with the DCI format; and determining an antenna port configuration for one or more demodulation reference signals based on the DCI message, the configuration information, and the bit-width value.

System and method for DMRS antenna port indication for URLLC

The disclosure describes mechanisms for reliability enhancement on control channel and data channel and mechanisms in URLLC. An apparatus of a RAN node for URLLC includes baseband circuitry to configure at least one DCI for scheduling transmission of at least one PDSCH content having same information. For each DCI, the baseband circuitry determines a CORESET for transmitting the DCI. The disclosure further describes mechanisms for the support of low latency transmission in URLLC. To improve peak data rate and spectrum efficiency in FDD system, the RAN node configures a DCI for scheduling data transmission using blank resources of a self-contained slot structure. Further, CBG-based transmission with separate HARQ-ACK feedback is provided to configure a DCI for scheduling data transmission of a TB and to divide the TB into multiple CBGs, and to configure uplink control data to carry separate HARQ feedback for the CBGs.

Enhancement of performance of ultra-reliable low-latency communication

Systems, apparatuses, methods, and computer-readable media are provided for a user equipment (UE) in a wireless communication system using an unlicensed spectrum. The UE includes a processor circuitry and radio front end circuitry coupled with the processor circuitry. The processor circuitry is configured to determine UE processing time for a first physical downlink shared channel (PDSCH) transmission and a second PDSCH transmission, and an additional processing time corresponding to the first and the second PDSCH transmissions. The processor circuitry is configured to process a hybrid automatic repeat and request acknowledgement (HARQ-ACK) assessment information for inclusion in a subframe on a physical uplink control channel (PUCCH) following the UE processing time and the additional processing time. The radio front end circuitry is configured to receive the first and the second PDSCH transmissions from a base station, and transmit the HARQ-ACK assessment information on the PUCCH to the base station.

User equipment processing time relaxation for multi-DCI NC-JT PDSCH reception

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.

Downlink transmission in TDD supporting feNB-IoTs

Technology for an eNodeB operable to apply scrambling to coded bits transported via a physical downlink shared channel (PDSCH) to a user equipment (UE) is disclosed. The eNodeB can generate a code word that comprises coded bits for transmission to the UE. The UE can be a bandwidth-reduced low complexity (BL) UE or a coverage enhancement (CE) UE. The eNodeB can identify, for the BL UE or the CE UE, a scrambling sequence to be applied to the coded bits. The scrambling sequence can be initialized using a defined initialization value (c). The eNodeB can apply the scrambling sequence with the defined initialization value to the coded bits to obtain scrambled coded bits. The eNodeB can encode the scrambled coded bits for transmission to the UE via the PDSCH.

Scrambling for control messages

Among other things, embodiments of the present disclosure are directed to the support of a new class of Reduced Capability (RedCap) New Radio (NR) user equipments (UEs), focusing on the simplification of various multiple input multiple output (MIMO) related features and operations. Other embodiments may be disclosed and/or claimed.

Support of simplified multiple input multiple output features for reduced capability user equipment in new radio systems

Various embodiments herein provide techniques for cancelation of one or more uplink (UL) transmissions from a user equipment (UE). The UE may receive an indication of a parameter d to use for determining a start of a reference UL resource (RUR). The parameter d may be UE-specific. The UE may further receive a physical downlink control channel (PDCCH) that includes a downlink control information (DCI) to indicate that a UL transmission is to be canceled in a RUR. The UE may determine a starting symbol of the RUR based on the parameter d. In embodiments, the UE may scale the parameter d based on a first subcarrier spacing (SCS) associated with the parameter d and a second SCS associated with the uplink transmission to obtain a scaled parameter d' that is used to determine the starting symbol of the RUR. Other embodiments may be described and claimed.

Techniques for cancelation of one or more uplink transmissions from a user equipment

Systems, devices, and techniques for indicating the number of repetitions for a downlink control information (DCI) message are described. A described technique includes transmitting an indication of a repetition number for a downlink control information (DCI) message having a predetermined format for transmit power control (TPC) of an uplink channel by a user equipment (UE); and transmitting, to the UE via a machine-type communications physical downlink control channel (MPDCCH), repetitions of the DCI message in accordance with the predetermined format and in accordance with the repetition number. The predetermined format can based on a DCI format 3 or 3A for bandwidth-reduced low-complexity or coverage enhanced (BL/CE) UEs.

Indication of the number of repetitions for dci format 3/3A for EMTC

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.

In an example computer-implemented method, a user equipment (UE) receives first configuration data including an indication of a search space set for monitoring a wireless network for an uplink cancellation command, and second configuration including an indication to activate monitoring of the wireless network for an uplink cancellation command. The UE further receives a first physical downlink control channel (PDCCH) including scheduling information for an uplink transmission. The UE monitors the wireless communications network for the uplink cancellation command in accordance with the search space set, and receives a second PDCCH from the wireless including the uplink cancellation command, where the uplink cancellation command includes an indication to cancel a first portion of the uplink transmission.
