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.

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: 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: A user equipment (UE) device comprising a processor configured to perform operations is described. In an exemplary embodiment, the operations include comprising establishing a sidelink session with a transmitting UE; configuring the sidelink session to support coordinated resource selection prior to performing the local sensing; performing a local sensing; receiving a PSCCH and a PSSCH from the transmitting UE. The transmitting UE reserves multiple resources. The processor is further configured to perform operations including determining whether a collision happens among the multiple reserved resources; and transmitting the coordination message to the transmitting UE.

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.

Abstract: This disclosure relates to techniques for providing control signaling for robust uplink data transmissions in a wireless communication system. A wireless device may be configured to perform an uplink transmission, including performing multiple repetitions of the uplink transmission. The wireless may select a beam for each repetition, and it may be the case that different repetitions are transmitted using different beams.

Abstract: This disclosure relates to techniques for receiving physical downlink control channel transmissions with improved reliability in a wireless communication system. A wireless device may establish a wireless link with a cellular base station. The wireless device may receive downlink control channel configuration information from the cellular base station. The downlink control channel configuration information may configure control resources associated with multiple transmission reception points in a search space for the wireless device. The wireless device may perform downlink control channel candidate blind decoding during a monitoring occasion configured by the search space configured with control resources associated with multiple transmission reception points.

Abstract: Interference measurement may include decoding a channel state information (CSI) reporting configuration received from a base station. The CSI reporting configuration may be associated with a set of resources for interference measurement. The first UE may be in communication with at least a first transmission and reception point (TRP) of a plurality of TRPs and at least a second TRP of the plurality of TRPs may also be in communication with a second UE that creates cross-link interference for the first UE. At the first UE, a cross-link interference measurement associated with the second UE may be performed using the CSI reporting configuration.

Abstract: A user equipment (UE), a base station, a baseband processor or other network device can determine a codebook subset configuration of a plurality of multiple-input multiple-output (MIMO) layers for antenna ports of a codebook. The codebook subset configuration can include a nested structure based on a codebook configured for a fully-coherent UE, or a codebook configured for a partially-coherent UE. Fully-coherent precoders, a set of partially-coherent precoders or a set of non-coherent precoders can be configured in the codebook subset configuration to reduce a number of precoders from the partially-coherent precoders or the non-coherent precoders.
