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 confirmation 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 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.

Abstract: An approach is described for an access node configured for ultra-reliable and low latency (URLLC) transmission using multi-transmission reception point (TRP) to a UE. The access node includes processor circuitry and radio front end circuitry. The processor circuitry is configured to allocate resource blocks into a first portion and a second portion based on a resource indication value (RIV), a length of contiguously allocated resource blocks (LRBS) and a fraction. The radio front end circuitry is configured to transmit the first portion to the UE via a first transmission reception point (TRP1), and transmit the second portion to the UE via a second transmission reception point (TRP2).

Abstract: Systems, methods, and apparatuses are provided for determining a number of physical downlink control channel (PDCCH) candidates and non-overlapped control channel elements (CCEs) for a UE configured with a plurality of component carriers having more than one subcarrier spacing (SCS). The plurality of component carriers are assigned to a number of cell groups. Each cell group includes a scheduling component carrier providing scheduling information for the other component carriers in the cell group. A reference slot window is selected based on an SCS of component carriers assigned to each cell group. And a number of PDCCH candidates and non-overlapped CCEs per the reference slot window are determined based on a number of and SCS of the component carriers in each cell group. Control information in a downlink radio frame is monitored by the UE based on the number of PDCCH candidates and non-overlapped CCEs.

Abstract: Systems, devices, and techniques for transmit power control (TPC) in wireless communication systems are described. A described technique performed by a user equipment (UE) includes signaling that enables transmit power control (TPC) accumulation; receiving, by the UE, downlink control information (DCI) messages corresponding to respective physical uplink shared channel (PUSCH) transmission occasions; determining, by the UE, power control adjustment states for the PUSCH transmission occasions; and transmitting, by the UE, in the PUSCH transmission occasions in accordance with the power control adjustment states. Determining the power control adjustment states can include selectively applying TPC accumulation to one or more of the power control adjustment states based on a determination that at least one of the PUSCH transmission occasions is out-of-order based on an arrival ordering of the DCI messages.

Abstract: A network device such as an evolved NodeB (eNB) or next generation NodeB (gNB) can configure a set of user equipment (UE) for cell reference signal (CRS) muting in order to provide better channel quality and power efficiency in communications. Where an eNB mutes CRS transmissions that are not needed by any UE, an improvement in downlink throughput and reduce connection drop rate can be generated. A CRS muting capability can be determined based on a user equipment (UE) capability information. According to the CRS muting capability of a UE, the CRS can be transmitted at frequency locations based on CRS muting configuration parameters.

Abstract: A user equipment (UE) can include processing circuitry configured to decode control information of a physical down-link control channel (PDCCH) received via a resource within a control resource set (CORESET) occupying a subset of a plurality of OFDM symbols within a slot. At least one of the symbols in the subset coincides with a pre-defined symbol location associated with a demodulation reference signal (DM-RS) of a PDSCII. The DM-RS can be detected within the slot, the DM-RS starting at a symbol location that is shifted from the pre-defined symbol location and following the subset of symbols. Downlink data scheduled by the PDCCH and received via the PDSCH can be decoded, where the decoding is based on the detected DM-RS.

Abstract: Embodiments of a User Equipment (UE), Generation Node-B (gNB) and methods of communication are disclosed herein. The UE may attempt to decode sidelink synchronization signals (SLSSs) received on component carriers (CCs) of a carrier aggregation. In one configuration, synchronization resources for SLSS transmissions may be aligned across the CCs at subframe boundaries in time, restricted to a portion of the CCs, and restricted to a same sub-frame. The UE may, for multiple CCs, determine a priority level for the CC based on indicators in the SLSSs received on the CC. The UE may select, from the CCs on which one or more SLSSs are decoded, the CC for which the determined priority level is highest. The UE may determine a reference timing for sidelink communication based on the one or more SLSSs received on the selected CC.
