Abstract: A base station may generate first configuration information to configure a first user equipment (“UE”) to operate using a first bandwidth within a wideband carrier of a cell, generate second configuration information to configure a second UE to operate using a second bandwidth within the wideband carrier of the cell, and cause transmission of the first and second configuration information to the first and second UEs, respectively. The base station may configure the first and second UEs based upon capabilities received from each UE, respectively.

Abstract: Techniques discussed herein can facilitate multi-transmission reception point (multi-TRP) operation for new radio (NR). One example apparatus may be employed at a user equipment (UE) and may comprise one or more processors configured to transmit uplink control information (UCI) on two physical uplink control channels (PUCCHs). The two PUCCHs occupy different symbols in the same slot.

Abstract: Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. A channel state information (CSI) report may include a CSI part 1 transmission and may be configurable to include a CSI part 2 transmission. The UE may determine a first number of coded modulation symbols per layer to be used for the CSI part 1 transmission on a physical uplink shared channel (PUSCH) without uplink shared channel (UL-SCH) data. The first number of coded modulation symbols per layer may be determined as: a minimum of a first term and a second term if the CSI report includes the CSI part 2 transmission; and the second term if the CSI report does not include the CSI part 2 transmission.

Abstract: Embodiments of the present disclosure describe methods, apparatuses, storage media, and systems for determining that a first physical uplink control channel (PUCCH) resource and a second PUCCH resource at least partially overlap, where the first PUCCH resource has a payload of a first size carrying a first uplink control information (UCI) in a first format, and the second PUCCH resource has a payload of a second size carrying a second UCI in a second format. Furthermore, the first UCI and the second UCI are multiplexed to form a combined payload to be carried by the first PUCCH resource in the first format or by the second PUCCH resource in the second format. Other embodiments may be described and claimed.

Abstract: Technology for a user equipment (UE) configured for communication of sounding reference signal (SRS) resources is disclosed. The UE can decode a radio resource control (RRC) signal indicating an SRS to transmit with a physical uplink control channel (PUCCH), wherein the PUCCH and the SRS are quasi co located (QCLed) based on a spatial received parameter. The UE can encode an SRS for transmission using the spatial received parameter. The UE can encode uplink control information (UCI) for transmission in the PUCCH using the spatial received parameter. The UE can have a memory interface configured to send to a memory the spatial received parameter.

Abstract: New radio (NR) Uplink (UL) transmissions in an NR physical UL channel can be configured for a user equipment (UE) to communicate with a base station (e.g., gNB). The structures and mechanisms for configured these communications different from long term evolution (LTE) in NR specifications. A UE can generate a UL transmission with symbols on the NR physical channel including demodulation-reference signal (DM-RS) symbols and uplink control information (UCI) symbols. The UL transmissions comprise a DM-RS symbol located at each first symbol with variable lengths. The UE generates the UL transmission as an NR physical UL channel with about a 50% DM-RS overhead with a same or more DM-RS symbols than UCI symbols in a sequential pattern (e.g., an alternating pattern). The UE further maps HARQ-ACK feedback on a PUSCH based a frequency first operation that initiates following the DM-RS symbol located at the first symbol.

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.
