Abstract: A user equipment (UE), or other network component can operate to configure channel state information (CSI) feedback in response to receiving a CSI-reference signal (CSI-RS) according to a hierarchical precoding scheme that selectively reduces a feedback overhead associated with the CSI feedback. The UE can operate to divide and further sub-divide a frequency band (e.g., a wideband, or particular frequency part) into a precoding hierarchy to generate precoders for conveyance to a base station, eNodeB (eNB), or next generation NodeB (gNB) via the CSI feedback.

Abstract: The implementations disclosed provide apparatus, systems, and methods for channel structure construction for a two-step random access channel (RACH) using a new radio (NR) user equipment (UE) wireless device. The wireless device includes one or more computer processors configured to generate a physical RACH (PRACH) preamble mapped to a physical uplink shared channel (PUSCH) resource unit. The PRACH preamble is associated with a preamble group indicating a configuration of the PUSCH. The preamble group has a size indicated by radio resource control (RRC) signaling performed by the wireless device. A message is encoded including the PRACH preamble and a payload carried by the PUSCH. The configuration of the PUSCH includes parameters for decoding the message. The wireless device couples communicatively to a base station using the PUSCH. The message is transmitted to the base station. The base station decodes the message based on the parameters of the PUSCH configuration.

Abstract: Configuring channel state information reference signal (CSI-RS) reporting at a network may include encoding a single CSI-RS reporting configuration for transmission to a user equipment (UE) that is in connected mode with both a first transmission and reception point (TRP) and a second TRP. The single CSI-RS reporting configuration may include a plurality of CSI-RS resource sets. Each of the plurality of CSI-RS resource sets may include a plurality of CSI-RS resources. At least one of the plurality of CSI-RS resource sets may include CSI-RS resources that correspond to the first TRP or the second TRP. A CSI measurement communication received from the UE may be decoded. The CSI measurement communication may be based on the single CSI-RS reporting configuration communication. Based on the CSI measurement communication, one or more downlink data transmissions may be scheduled.

Abstract: A base station or other network component (next generation NodeB (gNB)) can operate to transmit a channel state information reference signal (CSI-RS) for channel state information (CSI) feedback. The CSI feedback can be received as corresponding to one or more frequency parts at hierarchical precoding levels of a frequency band based on a hierarchical precoding scheme in response to providing the CSI-RS.

Abstract: A UE may receive multiple signals causing a Quasi co-location TypeD (QCL-TypeD) collision. To determine which of the multiple signals to select, the UE may use a certain option based on a type transmission scheme associated with each of the multiple signals. The options may include one of a priority rule for signal reception, a scheduling restriction, or a priority rule for QCL-TypeD selection.

Abstract: A UE for a 5G system is to perform a measurement during a network controlled small gap (NCSG). The NCSCI includes a first visible interruption length (VIL1), a measurement length (ML), a second visible interruption length (VIL2), and a visible interruption repetition period (VIRP). A UE capability indicates a length of one or both the VIL1 and the VIL2. NCSG pattern information provides the NCSG for the UE, in which the VIL1 and the VIL2 indicate when the UE is not expected to transmit and receive data on a serving carrier, the ML indicates when the UE is expected to transmit and receive data on the serving carrier, and the VIRP indicates a period in which to repeat the NCSG.

Abstract: A user equipment (UE) associated with a wireless communication system is disclosed. The UE comprises a processor configured to receive a first downlink control information (DCI) for scheduling a first physical downlink shared channel (PDSCH). The first DCI includes a non-numerical (NN) value of K1 for hybrid automatic repeat request (HARQ)-ACK feedback. The processor is further configured to determine a first priority class associated with the first PDSCH, and determine K1 value and priority class associated with one or more subsequent PDSCH received from the BS, until a selected PDSCH having a numerical K1 value and a same priority class as the first priority class is identified. Further, the processor is configured to provide HARQ-ACK feedback associated with the first PDSCH using a PUCCH/PUSCH occasion indicated by a second DCI scheduling the selected PDSCH.
