Abstract: Methods and apparatuses are provided for providing dynamic power sharing at a user equipment (UE). A first uplink transmission is configured on a secondary cell group (SCG). An offset from a starting symbol of the first uplink transmission is determined, by the UE, based on a physical uplink shared channel (PUSCH) preparation time for a PUSCH timing capability. Based on the offset, a group of overlapping uplink transmissions on a master cell group (MCG) is defined. A total power is shared among uplink transmissions in the group of overlapping uplink transmissions on the MCG and the first uplink transmission on the SCG.

Abstract: A method and user equipment are provided. The method includes receiving a scheduling of a transmission on a target cell that collides with a scheduled transmission on a source cell; determining a time duration from an ending symbol of a physical downlink control channel (PDCCH) scheduling the transmission on the target cell to a first symbol of the transmission on the source cell; determining a time value based on a physical uplink shared channel (PUSCH) preparation time and a subcarrier spacing (SCS) configuration; and determining that the time duration is greater than the time value and, in response, performing the transmission on the target cell and cancelling the transmission on the source cell.

Abstract: A method and system for determining a physical uplink control channel (PUCCH) resource are provided. A last physical downlink control channel (PDCCH) in a monitoring occasion (MO) with a largest MO index, from among a plurality of MOs, on a serving cell with a largest cell index, from among a plurality of serving cells, is identified based on a search space identifier (ID) independent of a control resource set (CORESET) index. The PUCCH resource is determined from the last PDCCH.

Abstract: A method and a user equipment (UE) are provided for resource allocation. The UE receives repeated physical downlink control channels (PDCCHs) from a network. Each of the repeated PDCCHs includes downlink control information (DCI) that schedules reception of a same physical downlink shared channel (PDSCH) at the UE. The UE determines resources for at least one of transmission and reception at the UE, from a PDCCH having a latest start symbol or a latest ending symbol among the repeated PDCCHs. The repeated PDCCHs are received in accordance with the UE and the network communicating using a multi-transmission reception point (TRP) repetition scheme or a multi-TRP multi-chance scheme.

Abstract: Methods and apparatuses are provided in which a UE reports capability information indicating a first set of pairs and a second set of tuples. Each pair indicates serving cells configured for per-slot and per-span monitoring. Each tuple indicates serving cells configured for per-slot and per-span monitoring in an MCG and an SCG. A first pair of values for the MCG and a second pair of values for the SCG are received. A first value in each pair is a maximum number of serving cells configured for per-slot monitoring, and a second value in each pair is a maximum number of serving cells configured for per-span monitoring. A monitored candidate limit per slot is determined for the MCG and the SCG based on the first value. A monitored candidate limit per span is determined for the MCG and the SCG based on the second value.
