Certain aspects of the present disclosure provide techniques for aperiodic channel state information (A-CSI) transmission with slot aggregation. A method that may be performed by a user equipment (UE) includes receiving a grant scheduling a slot aggregated transmission in a plurality of aggregated slots and triggering an aperiodic channel state information (A-CSI) transmission in one of the plurality of aggregated slots. The method includes determining one or more of the plurality of aggregated slots to transmit the A-CSI transmission. The method includes transmitting the A-CSI transmission in the determined one or more of the plurality of aggregated slots.

A method by a user equipment (UE) is described. The method includes receiving, from a base station, a first radio resource control (RRC) parameter related to a first search space set, to receive a second RRC parameter related to a CORESET wherein the CORESET is associated with the first search space set, monitoring a set of PDCCH candidates for the first search space set in the CORESET, wherein the CORESET comprises one or more sets of consecutive OFDM symbols within a first time duration, the number of consecutive OFDM symbols for each set is determined based on the second RRC parameter, the first time duration is determined based on a RRC parameter included in the first parameter. The first RRC parameter include a third RRC parameter indicating a first symbol for each of the one or more than one sets of consecutive OFDM symbols within a slot, the first duration is determined as one slot, the CORESET comprises one or more sets of consecutive OFDM symbols within a slot.

A method comprises transmitting an Activation/Deactivation MAC CE to indicate or update the association between aperiodic SRS triggering state(s) and the aperiodic SRS resource set(s) for the SRS request field value carried by DCI format 0_1 or 1_1 or DCI format 2_3 with a higher layer parameter srs-TPC-PDCCH-Group=typeB or the SRS CC set(s) for the SRS request field value carried by DCI format 2_3 with the higher layer parameter srs-TPC-PDCCH-Group=typeA.

Disclosed are a method and apparatus for repeatedly transmitting an uplink in a wireless communication system. A method by which a terminal repeatedly transmits a physical uplink shared channel (PUSCH), according to an embodiment of the present disclosure, comprises the steps of: receiving configuration information related to repeated transmission of the PUSCH; receiving downlink control information (DCI) for scheduling of the PUSCH; and repeatedly transmitting the PUSCH N times (an integer, greater than 1, of N) on the basis of the configuration information and the DCI. The PUSCH transmitted N times is circularly and sequentially mapped to a plurality of transmission configuration indicator (TCI) states in an ascending order, may be grouped into M PUSCH groups (an integer, greater than 1, of N) for each PUSCH to which the same TCI is mapped, and frequency hopping may be individually applied to the M PUSCH groups.

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for transmitting sounding reference signal (SRS) resources with frequency hopping. In some implementations, a user equipment (UE) may use different SRS ports, different antenna ports, different numbers and sizes of SRS resources, different periodicities, different offsets, different transmission comb values, different number of symbols, different power control parameters, and/or different transmission comb offset values for SRS transmissions on different frequency subbands of the frequency hopping pattern to ensure that sounding operations cover all antennas of the UE, cover the entire frequency range of interest, and provide sufficiently dense SRS transmissions from which a base station can determine the best channel for DL transmissions while also using a minimum amount of SRS resources and consuming minimal power in the UE.

The technology includes: an input setting unit that sets a set Path of paths, a set Edge of edges, a maximum bandwidth Max, a bandwidth p.bandwidth required by a path p, and a set e.paths of paths that include an edge e, as input to a bandwidth allocation plan problem for creating a bandwidth allocation plan for paths so as to satisfy a condition of minimizing a bandwidth allocated for the paths of the set Path as a whole under a predetermined constraint condition; and an optimization function creation unit that creates the optimization function using the input.

This disclosure provides systems, methods and apparatus for aperiodic measurement configurations. In one aspect, delaying transitioning of a secondary cell group (SCG) to an active state until a next synchronization signal block (SSB) or periodic reference signal may result in an excessive delay in obtaining network resources of the SCG. Some aspects described herein enable a base station (BS) to transmit signaling using a master cell group (MCG) cell to schedule resources for an aperiodic reference signal transmission and measurement using the SCG. For example, the BS may transmit signaling to a user equipment (UE) to identify a reference signal resource for an aperiodic reference signal transmission and measurement. In this case, the BS may transmit the aperiodic reference signal using an SCG cell, and the UE may measure the aperiodic reference signal and provide a report identifying the measurement of the aperiodic reference signal.

Embodiments of the present application provide methods for checking UE capability match, an AMF, a base station, and a storage medium. The method includes: determining to send a UE capability match request to a base station during a registration procedure initiated by the UE; sending a request for setting up a UE's access stratum (AS) security context to the base station, and sending the UE capability match request to the base station after it is determined that the base station completes setup of the AS security context; receiving a UE capability match acknowledgement returned from the base station. By the method according to the embodiment of the application, the problem that the base station does not respond to the UE capability match process requested by the AMF, which results in that the AMF cannot issue an indication of IMS voice over PS session to the UE during the registration process, can be avoided, and thus the UE can normally obtain IMS voice service.
