    Abstract: Various manners of reporting channel state information (CSI) measurements in a multiple transmission and reception point (multi-TRP) configuration are provided. A UE may perform channel state information (CSI) measurements for a channel measurement resource (CMR) for the first gNB and at least one interference measurement resource (IMR) for the at least one second gNB, determine a configuration for a CSI report for the CSI measurements including a channel quality indicator (CQI) measurement for the CMR and the at least one IMR and transmit the CSI report to at least one of the first gNB and the at least one second gNB.

    Abstract: Apparatuses, systems, and methods for a wireless device to disable a HARQ feedback in either a semi-static way or in a dynamic way and to perform HARQ optimization. The wireless device may be configured to receive a first set and a second set of HARQ process numbers, where the first set and the second set of HARQ process numbers correspond to a first set and a second set of HARQ processes respectively, where each HARQ process in the first set of HARQ processes is configured to enable a HARQ feedback, and where each HARQ process in the second set of HARQ processes is configured to disable or enable a HARQ feedback. The wireless device may be configured to receive a grant configuration or a SPS, where the grant configuration or the SPS include a flag indicating whether a HARQ-based retransmission is disabled.

    Abstract: Some embodiments include an apparatus, method, and computer program product for tracking reference signal (TRS) support of high speed use cases of 5G communications in a single frequency network (SFN), where a user equipment (UE) can measure a Doppler offset of a combined signal from two or more transmission reception points (TRPs) of the 5G communications system. A 5G node B (gNB) node can transmit a periodic, semi-persistent (SP), or aperiodic TRS with high measurement density that the UE uses to measure a Doppler offset of a combined signal. For example, the gNB can: trigger the aperiodic TRS based on a downlink assignment; and/or use lower layer signaling to arrange to transmit a semi-persistent TRS or a periodic TRS with a reduced periodicity. In some embodiments, the gNB can measure the Doppler offset based on an uplink signal, and transmit a TRS based on a pre-compensated Doppler frequency.

    Abstract: Various user equipment (UE) operations performed when the UE is in multiple Downlink Control Information (multi-DCI) based multiple transmission and reception point (multi-TRP) configuration. The operations receiving, from one of the first or second gNBs, one or more cell reference signal (CRS) rate matching patterns, wherein the one or more CRS rate matching patterns comprise an indication of a control resource set (CORESET) pool for each of the one or more CRS rate matching patterns and applying the one or more CRS rate matching patterns to a CORESET for a Physical Downlink Shared Channel (PDSCH) based on the indication of the CORESET pool.
