Abstract: Some embodiments include an apparatus, method, and computer program product for facilitating processing times in a 5G wireless communications system. When operating at higher frequency subcarrier spacing (SCS), slot times for receiving and/or transmitting data between user equipment (UE) and a 5G Node B (gNB) become shorter. Because of this, some UE may face difficulty in processing physical downlink shared channel (PDSCH), physical uplink shared channel (PUSCH), and/or physical downlink control channel (PDCCH) data with sufficient speed. To address potential limitations, a flexible minimum processing time may be used to accommodate different UE processing capabilities. The UE may report its processing capabilities to the gNB. The gNB may then schedule communications according to the UE’s processing capabilities. The gNB may consider whether the UE implements a single or multiple processing engines. Further, the gNB may apply single-slot and/or multi-slot scheduling techniques to also prevent timing issues.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for generating a report result based on a set of measurements performed at measurement gaps during a reporting period. The set of measurements are performed on a reference signal at a first bandwidth part (BWP) or a second BWP when BWP switching is performed. The first BWP has a first measurement gap configuration, the second BWP has a second measurement gap configuration. The measurement gaps of the reporting period are configured according to a third measurement gap configuration that is determined based on the first measurement gap configuration and the second measurement gap configuration.

Abstract: Some embodiments include an apparatus, method, and computer program product for enhanced Hybrid Automatic Repeat Request (HARQ)-ACK in a fifth generation (5G) wireless communications system. A user equipment (UE) can receive, during a HARQ-ACK window, a semi-persistent scheduling (SPS) Physical Downlink Shared Channel (PDSCH) transmission or a Physical Downlink Control Channel (PDCCH) transmission corresponding to a SPS PDSCH release. The UE can generate a Hybrid Automatic Repeat Request (HARQ)-ACK information bit corresponding to the reception. The UE can be configured with an offset value, k, and a length, l, of the HARQ-ACK window associated with an uplink transmission slot n, of a Physical Uplink Control Channel (PUCCH) transmission, and determine a starting slot of the HARQ-ACK window as n−k. When a corresponding valid uplink transmission slot is not available, the UE can transmit the HARQ-ACK information bit in the uplink transmission slot n of the PUCCH transmission.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing resource allocations for feedback channels in sidelink communications. A UE can be configured to receive a physical sidelink control channel (PSCCH) transmission or a physical sidelink shared channel (PSSCH) transmission over a sidelink between the UE and a second UE for sidelink communication. The UE can allocate a set of resource elements within an interlace including multiple resource blocks to carry physical sidelink feedback channel (PSFCH) content associated with the received PSCCH transmission or PSSCH transmission, where the set of resource elements includes a first resource element in a first resource block of the interlace, and a second resource element in a second resource block of the interlace. The UE can be further configured to transmit the PSFCH content carried by the set of resource elements as a PSFCH transmission to the second UE.

Abstract: Mechanisms are provided for a user equipment (UE) to perform joint channel estimation for multiple downlink transmissions. A method performed by a UE can include reporting, to a base station, a capability of the lIE to perform joint channel estimation, receiving a configuration for joint channel estimation, where the configuration includes a time domain window (TDW) indicating a duration of the joint channel estimation, and further determining whether to perform the joint channel estimation. Based on a determination to perform the joint channel estimation, the method can include determining an actual time domain window within the TDW for performing the joint channel estimation, and performing the joint channel estimation within the actual time domain window for a first physical downlink shared channel (PDSCH) transmission based on a first demodulation reference signals (DMRS), and a second PDSCH transmission based on a second DMRS.

Abstract: Methods and apparatuses are disclosed for performing fast beam switching in a high-frequency wireless communication environment. Higher frequencies reduce transmission wavelength, which allows for an increased number of antennas and an increased number of beams. Therefore, beams become narrower and are more prone to failure. The UE must be capable of quickly identifying the beam failure and switching to a new beam. Therefore, the UE is capable of receiving multiple beams from the base station and configures both for testing and immediate use. In some cases, the UE can receive multiple beams for testing and assumes a default beam while feeding back to the base station a preferred beam. To support the larger number of available beams, MAC-CE and DCI are modified to identify this increased number of states. Alternatively, two MAC-CEs are sent, each containing a different group of states, and the DCI identifies both the group and the selected state.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing downlink and uplink scheduling in communication above 52.6 GHz. For example, some aspects of this disclosure relate to a base station. The base station includes a transceiver configured to communicate over a wireless network with a user equipment (UE) and a processor communicatively coupled to the transceiver. The processor determines that the communication between the base station and the UE is in a frequency range above 52.6 GHz. In response to the determination, the processor disables a frequency main resource assignment (FDRA), modifies a Resource Block Group (RBG) size, or modifies a Resource Indication Value (RIV) determination. The processor generates a Downlink Channel Indicator (DCI) based at least on one or more of the disabled FDRA, the modified RBG size, or the modified RIV determination. The processor transmits, using the transceiver, the DCI to the UE.

Abstract: Provided is a method for a user equipment (UE). The UE obtains, from a network device, a first configuration information. The first configuration information indicates a first resource set for an aperiodic Sounding Reference Signal (AP-SRS). The first resource set for the AP-SRS includes a first list of slot offsets. The UE decodes a second configuration information from the network device. The second configuration information indicates a reference slot and a first slot offset of the first list of slot offsets. The UE generates the AP-SRS for transmission to the network device based on the reference slot and the first slot offset.
