    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: A user equipment (UE) monitors a Physical Downlink Control Channel (PDCCH). The UE receives a configuration for a physical downlink control channel (PDCCH) including repetitions for PDCCH candidates comprising first PDCCH data, wherein the PDCCH candidates are repeated across multiple durations of a DL resource grid, detects, based on a repetition detection scheme, each of the PDCCH candidates and combines soft bits from each of the PDCCH candidates, wherein the combined soft bits are jointly decoded to determine the first PDCCH data and calculates a number of blind decodes (BDs) for the durations of the DL resource grid carrying the PDCCH candidates, wherein at least one BD value for the PDCCH candidates is scaled by a scaling factor for the calculation of the number of BDs.
