Abstract: Systems and methods for the use of smart repeater (SMR) control information from a base station to an SMR to control aspects of SMR operation are disclosed herein. The SMR control information may control the operation of to either or both of an SMR synchronization signal block (SSB) beam sweep or an SMR channel state information reference signal (CSI-RS) beam sweep. An SMR may report, to a base station, SMR capability information; receive, from the base station, SMR control information corresponding to the SMR capability information that includes a first portion configuring an SSB beam sweep and/or a second portion configuring a CSI-RS beam sweep; and perform, based on the SMR control information, one or both of the SMR SSB beam sweep and the SMR CSI-RS beam sweep. Systems and methods for signaling the SMR control information between the SMR and the base station are also provided.

Abstract: This disclosure describes the following enhancement to improve the PDCCH reliability: PDCCH aggregation and multi-beam PDCCH reception for a 5G wireless communication system. The disclosed techniques entail obtaining repeated PDCCH by processing a PDCCH-Config, ControlResourceSet, or SearchSpace configuration parameter including an information element (IE) indicating a number of consecutive slots in which the PDCCH is repeated. In another embodiment, a gNB generates the PDCCH-Config, ControlResourceSet, or SearchSpace configuration parameter for configuring a UE to receive the repeated PDCCH and employ the multi-beam PDCCH reception.

The CSI-ReportConfig configuring a port selection codebook comprising a port selection matrix W1, a combinational coefficient matrix W2, and a frequency basis selection matrix Wf. Based on the CSI-ReportConfig, the determines, for the port selection matrix W1, up to L CSI reference signal (CSI-RS) ports out of P CSI-RS ports configured for measuring and reporting CSI. For the frequency basis selection matrix Wf, the UE determines up to Mv frequency basis out of N frequency basis. For the combinational coefficient matrix W2, the UE determines up to L*Mv entries per layer.

Abstract: A communication system provides reliable wideband communications with reduced power consumption in a user equipment (UE) receiver. A UE may include receiver circuitry to receive a radio frequency (RF) signal from a wireless network and output an analog baseband signal. The RF signal includes M copies of a duplicated signal in a frequency domain. The analog baseband signal includes the M copies of the duplicated signal uniformly offset from one another in the frequency domain by a bandwidth F and including a gap between adjacent copies. The UE further includes an anti-aliasing analog filter an analog to digital converter (ADC). The ADC samples an output of the anti-aliasing analog filter at a sampling frequency selected to obtain a digital baseband signal comprising a combined digital copy of the M copies of the duplicated signal folded over each other.

Abstract: Precoders are provided for multi-panel uplink (UL) transmission. A codebook may support asymmetric multi-panel UL transmission or super UL transmission where new radio (NR) and long-term evolution (LTE) transmissions may be provided through different antenna panels of a user equipment (UE). Sounding reference signal (SRS) enhancement provides support for multi-panel transmission. The UE transmits an indication of a UE capability based on an antenna structure comprising multiple antenna panels of the UE. Further, the UE determines, at the UE, one or more precoders to use for UL transmissions based at least in part on the UE capability, wherein the one or more precoders include a polarization co-phasing factor, an antenna panel co-phasing factor, and a combining weight for antennas for a same polarization. Additionally, the UE transmits, from the multiple antenna panels, the UL transmissions using the one or more precoders.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing mechanisms for a network to use Doppler shift pre-compensation values for communicating Tracking Reference Signal (TRS) to a user equipment (UE) and for implementing mechanisms for triggering the UE to measure the Doppler shift pre-compensated TRS. Some aspects of this disclosure relate to a base station including a processor that determines a Doppler shift pre-compensation value associated with the UE in response to determining that the UE is moving with a speed greater than a threshold. The processor further generates an aperiodic Tracking Reference Signal (AP-TRS) or a semi persistent TRS (SP-TRS) for the UE. The AP-TRS or the SP-TRS is decoupled from a periodic TRS (P-TRS). The processor further transmits the AP-TRS or the SP-TRS to the UE. The AP-TRS or the SP-TRS can be used for time and frequency synchronization.

Abstract: Disclosed are methods and apparatus for multiplexing of uplink control information on uplink data channels in wireless communication. It may be determined that transmission of a plurality of physical uplink shared channels (PUSCHs) are scheduled. The transmission of the plurality of PUSCHs may overlap with transmission of an uplink control information (UCI). At most one of the plurality of PUSCHs on to which the UCI is multiplexed may be determined based on a Downlink Assignment Index (DAI) value. The plurality of PUSCHs may be set with no more than one PUSCH having the DAI value not equal to four. Thereafter, the determined PUSCH is transmitted with the UCI multiplexed on it.
