Abstract: A method and user equipment are provided. The method includes receiving a scheduling of an uplink (UL) signal on a target cell that collides with a UL signal on a source cell; determining a time duration from an ending symbol of a physical downlink control channel (PDCCH) scheduling the UL signal on the target cell; determining that a first symbol of the UL signal on the source cell is after the time duration from the ending symbol of the PDCCH; and dropping at least a portion of the UL signal on the source cell in response to determining that the first symbol of the UL signal on the source cell is after the time duration from the ending symbol of the PDCCH.

Abstract: A device may include a transceiver configured to access a communication network including a primary cell and a secondary cell, and a device controller configured to receive, on the secondary cell, scheduling information for the primary cell, and monitor a common search space for the primary cell. The device controller may be configured to selectively monitor the common search space for broadcast information. The device controller may be configured to selectively monitor the common search space based on a type of the common search space on the primary cell. A method may include scheduling, by a first scheduling mechanism, a primary cell, wherein the first scheduling mechanism comprises scheduling the primary cell by a secondary cell, scheduling, by a second scheduling mechanism, the primary cell, and deactivating the secondary cell based on switching from the first scheduling mechanism to the second scheduling mechanism. The second scheduling mechanism may include self-scheduling.

Abstract: A method of implementing beam failure recovery for a multi-transmission-and-reception-point (M-TRP) transmission including a first transmission from a first TRP and a second transmission from a second TRP may include: receiving a first set of reference signals (RSs) corresponding to the first TRP and a second set of RSs corresponding to the second TRP; determining that the first set of RSs indicates a beam failure instance (BFI) specific to the first TRP, and responsively updating a first BFI counter specific to the first TRP; determining that a beam failure with respect to the first TRP has occurred based on a count of the first BFI counter equaling or surpassing a first BFI counter threshold; and performing a BFR process for the first TRP responsive to determining that the beam failure with respect to the first TRP has occurred.

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.

Abstract: A method for cross carrier scheduling can include: determining that a candidate DCI for a UE schedules a DG PDSCH that at least partially overlaps an SPS PDSCH for the UE, wherein the DCI is configured to be transmitted on a first CC having a first SCS, and the DG PDSCH is configured for transmission on a second CC having a second SCS different from the first SCS; determining a timing gap based on the smallest of the first SCS and the second SCS; determining that an available time between the scheduled SPS PDSCH and the DCI is equal to or greater than the timing gap; cancelling the SPS PDSCH responsive to determining that the available time between the scheduled SPS PDSCH and the DCI is equal to or greater than the timing gap; and transmitting the DCI to the UE.

Abstract: Methods and apparatuses are provided for receiving, from a user equipment (UE) configured to process a first priority channel using a first monitoring span based on the first priority channel during one or more time periods, at least one parameter indicating a minimum amount of time required by the UE to process the first priority channel using a second monitoring span based on the first priority channel and a second priority channel. The one or more time periods are based on minimum processing capabilities of the UE. Based on the at least one parameter, the UE is caused to be reconfigured with at least one time offset to increase at least one time period of the one or more time periods for processing the first priority channel.

Abstract: A system and method for setting blind detection and control channel element monitoring limits in a carrier aggregation scheme. In some embodiments, the method includes: receiving, by a network from a first user equipment (UE), a declaration of capabilities of the first UE; sending, by the network, to the first UE, a first search space (SS) configuration for a first component carrier in a carrier aggregation (CA) scheme; and sending, by the network, to the first UE, a second search space configuration for a second component carrier in the carrier aggregation scheme. The first search space configuration may define a first set of monitoring occasions, the second search space configuration may define a second set of monitoring occasions (MOs), and an aligned span pattern, corresponding to the first set of monitoring occasions and the second set of monitoring occasions, may comply with the declaration of capabilities of the first UE.
