Various embodiments herein provide techniques related to methods or techniques to be performed by a user equipment (UE). In some embodiments, a technique may include identifying that a failure of a listen-before-talk (LBT) procedure is related to alignment with a u-FFP. The technique may further include notifying, based on the identification, a higher layer about the failure of the LBT procedure. Other embodiments may be described and/or claimed.

Further enhancements to ultra-reliable low-latency communication (URLLC) in unlicensed spectrum

A user equipment (UE) configured for operation in a fifth-generation new radio (5GNR) system may multiplex high-priority (HP) hybrid automatic repeat request acknowledge (HARQ-ACK) bits corresponding to a first HARQ-ACK code-book with low-priority (LP) HARQ-ACK bits corresponding to a second HARQ-ACK codebook onto a physical uplink control channel (PUCCH) transmission to a gNode B (gNB). The UE may be configured with the first HARQ-ACK codebook and the second HARQ-ACK codebook of different priorities. The HP HARQ-ACK bits may be encoded with a first maximum code rate (maxCodeRate) and the LP HARQ-ACK bits may be encoded with a second maximum code rate. The maximum code rates may be configured to the UE via RRC signalling per PUCCH format.

Multiplexing of uplink control information (UCI) with different physical layer priorities

A user equipment (UE) configured for operation in a fifth-generation new radio (5G NR) system may be configured for multi physical downlink shared channel (PDSCH) scheduling and may decode a first downlink control information (DCI) and a second DCI received from a gNodeB (gNB). The first DCI may schedule multiple PDSCHs and the second DCI may schedule one or more PDSCHs. The UE may check the timing relations of the scheduled PDSCHs for validity when the first DCI and the second DCI end at a same symbol. When the multiple PDSCHs scheduled by the first DCI and the one or more PDSCHs scheduled by the second DCI are determined to have overlapping time spans, the UE may identify all the PDSCHs scheduled by the first DCI the second DCI as invalid.

Multi-TTI scheduling of PDSCH and PUSCH by DCI

Various embodiments herein relate to techniques that may improve coverage for a physical random access channel (PRACH). Additionally, some embodiments may relate to techniques for repetition of a channel state information (CSI) report on a physical uplink shared channel (PUSCH) for coverage enhancement. Other embodiments may be described and/or claimed.

Coverage for physical random access channel and repetition of CSI report on PUSCH for coverage enhancement

Various embodiments herein provide techniques paging early indication for a user equipment in an idle and/or inactive state. Other embodiments may be described and claimed.

Techniques for paging early indication for UE power saving in idle/inactive state

A network device (e.g., a user equipment (UE), a new radio NB (gNB), or other network component) can process or generate a dynamic Physical Uplink Shared Channel (PUSCH) repetition indication that provides parameters about PUSCH repetition(s) for the uplink within one, two or other number of slots of a New Radio (NR) communication as an Ultra-Reliable Low-Latency Communication. The network device can also process or generate one or more multiple Configuration-Grant (CG) PUSCH configurations. The presence of a repetition level bit-field in a Downlink Control Information (DCI) carrying UL grant or activating UL configured grant PUSCH can be controlled by semi-static UE-specific RRC signaling enabling or disabling the dynamic signaling of PUSCH repetitions.

Physical uplink shared channel enhancements for new radio ultra-reliable low-latency communication

Various embodiments herein provide techniques for downlink and uplink resource mapping for full duplex communication, e.g., non-overlapping sub-band-full duplex (NOSB-FD) communication that includes a frequency resource for uplink communication and a frequency resource for downlink communication. Also described are techniques for user equipment (UE) behavior associated with a non-cell defining synchronization signal block (NCD-SSB). Other embodiments may be described and claimed.

Techniques for downlink and uplink resource mapping for full duplex and non-cell defining synchronization signal block

Described is an apparatus of a User Equipment (UE). The apparatus may comprise a first circuitry, a second circuitry, and a third circuitry. The first circuitry may be operable to process one or more configuration transmissions from the gNB carrying a rule for Uplink (UL) collisions and process a first Downlink (DL) transmission and a second DL transmission. The second circuitry may be operable to identify a first UL transmission for the first DL transmission and a second UL transmission for the second DL transmission, the first UL transmission overlapping with the second UL transmission in at least one Orthogonal Frequency Division Multiplexing (OFDM) symbol. The third circuitry may be operable to generate at least one of the first UL transmission and the second UL transmission in accordance with the rule for UL collisions.

Handling collision for mini-slot-based and slot-based transmission

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.
