Abstract: Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The UE may receive control signaling to configure transmission of: a first physical uplink control channel (PUCCH) that includes first uplink control information (UCI) of a first UCI type; and a second PUCCH that includes second UCI of a second UCI type. In some cases, if the transmissions of the first PUCCH and the second PUCCH would overlap in a number of slots, the UE may, if the first and second UCI types are not of the same priority: transmit, in the overlapping slots, the PUCCH that includes the UCI type of highest priority; and refrain from transmission in the overlapping slots, and without postponement of the transmission, of the PUCCH that includes the UCI type of lowest priority.

Abstract: Disclosed herein are apparatuses, systems, and methods using or implementing dynamic resource allocation (DRA) of resources for machine-type communication (MTC), as a secondary partition within a system bandwidth. Allocations outside the secondary partition are configured as a primary partition for other than MTC. Apparatuses may perform MTC communications within the secondary partition when DRA configuration information includes allocation information for the secondary partition and the apparatus is configured for MTC. Otherwise, if the apparatus is other than MTC, the apparatus may refrain from performing communications in the secondary partition. Other embodiments are described.

Abstract: A user equipment (UE) or network device gNB can process or generate downlink control information transmissions for new radio (NR) systems or networks based on a compact DCI format. The DCI can include a grouped broadcast message for reduced signaling overhead that comprises random access response (RAR) message, a paging message, a system information block (SIB) message, another message information type, or any combination thereof. The DCI transmission can be determined as comprising paging information based on a direct indication in a physical downlink control channel (PDCCH) only or both in the PDCCH and a physical downlink shared channel (PDSCH) based on a flag field of the DCI transmission. Other configurations can also further reduce signaling overhead additionally or alternatively.

Abstract: Provided herein are method and apparatus for channel coding in the fifth Generation (5G) New Radio (NR) system. An embodiment provides an apparatus for a Next Generation NodeB (gNB), including circuitry, which is configured to: generate Downlink Control Information (DCI) payload for a NR-Physical Downlink Control Channel (NR-PDCCH); attach Cyclic Redundancy Check (CRC) to the DCI payload; mask the CRC with an Radio Network Temporary Identifier (RNTI) using a bitwise modulus 2 addition operation, wherein the number of bits for the RNTI is different from the number of bits for the CRC; and perform polar encoding for the DCI payload with the masked CRC.

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.

Abstract: Future LTE systems will support massive carrier aggregation that necessitates transmission of a large number of acknowledgement signals (HARQ-ACKs) in response to downlink data transmitted over multiple component carriers. Described herein are methods and apparatus for efficiently transmitting HARQ-ACK and periodic channel state information (P-CSI) bits over the PUCCH (physical uplink control channel).

Abstract: An apparatus configured to be employed in a user equipment (UE) associated with a new radio (NR) system is disclosed. The apparatus comprises a processing circuit configured to determine an NR-physical uplink control channel (PUCCH) resource to be utilized by the UE, for a transmission of a hybrid automatic repeat request (HARQ)-acknowledge (ACK) feedback message to a gNodeB, wherein the determined NR-PUCCH resource comprises a HARQ-PUCCH resource. In some embodiments, the HARQ-ACK feedback message comprises a feedback message generated at the UE in response to processing a downlink (DL) data transmission signal comprising data received from the gNodeB. In some embodiments, the processing circuit is further configured to generate a transmission of the HARQ-ACK feedback message using the determined HARQ-PUCCH resource.

Abstract: Technology for a Next Generation NodeB (gNB) operable to encode downlink control information (DCI) for transmission to a user equipment (UE) is disclosed. The gNB can identify DCI for transmission from the gNB. The gNB can determine that a size of the DCI exceeds a defined threshold. The gNB can divide the DCI into one or more DCI segments. Each DCI segment can include header information to enable the one or more DCI segments to be assembled at the UE. The gNB can encode the one or more DCI segments of the DCI for transmission from the gNB to the UE.
