    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.

    Abstract: A user equipment (UE) is configured to transmit an uplink transmission with a bundling of demodulated reference signals (DMRS), transmit the uplink transmission, receive a downlink control information (DCI) transmission from the base station between repetitions of the uplink transmission, wherein the DCI indicates a transmission power control (TPC) information element (IE) indicating remaining ones of the repetitions of the uplink transmission should be transmitted using a new transmission power and determine if the DCI is a group common (GC)-DCI Format 2_2.

    Abstract: A computer readable storage medium, a user equipment, a method and an integrated circuit that are used to perform operations. Operations include receiving, from a network, a plurality of Physical Downlink Shared Channel (PDSCH) transmissions in slots of a hybrid automatic repeating request acknowledgement (HARQ-ACK) window, decoding each of the PDSCH transmissions in the slots of the HARQ window, determining a HARQ-ACK feedback for each PDSCH transmission in the HARQ-ACK window, bundling the HARQ-ACK feedback for at least two of the PDSCH transmissions and reporting the bundled HARQ-ACK feedback for the HARQ window to the network.

    Abstract: Embodiments are disclosed for capability reporting for antenna switching, AS, sound reference signals, SRS. A user equipment (UE) can transmit a capability report for AS SRS that includes a plurality of receive antenna (e.g., six or eight receive antenna), and receive SRS instructions based on the capability report. The UE can transmit a first temporary capability reduction for a duration, and transmit a first SRS according to the first temporary capability reduction and the SRS instructions, while maintaining phase continuity. To maintain phase continuity, the UE can calibrate one or more SRS ports participating in the AS SRS to transmit with substantially a same transmit power. The UE can determine that a second SRS overlaps an other transmission in a time domain, determine that the other transmission has an absolute priority over the second SRS, and transmit the other transmission but not the second SRS.

    Abstract: The present application relates to devices and components including apparatus, systems, and methods for UE positioning. In an example, a UE transmits a sounding reference signal for positioning (SRSp) to a base station. The SRSp transmission can use frequency hopping and can rely on a window and/or a collision rule associated with the entire frequency hopping sequence or only a frequency hop of such a sequence. The window and/or collision rule can reduce the potential for signal collision with non-SRSp signals. Further, the UE can implement a low power high accuracy position (LPHAP) technique. In this technique, a fallback behavior or an SRSp transmission can be stopped if the UE is not able to accurately measure “N” configured reference signals, where “N” can be based on the positioning method.

    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.
