While LIN teaches “monitor one or more TRS resource sets in accordance with the availability indication”,
LIN does not expressively teach:

Nam, in the same field of endeavor, discloses:
wherein the TRS starts at a time after the availability indication is received in accordance with a time offset or an application delay (“.. a frequency offset of a TRS transmission may be varied in a TRS configuration to enhance resource tracking. For example, a base station may select a frequency offset parameter. The frequency offset parameter may indicate an offset relative to a reference frequency, and may be expressed in terms of a number of resource elements, a frequency band, a frequency bandwidth part, or the like. In some cases, the offset may be indicated for a set of symbol indexes within a particular transmission time interval (e.g., within a slot), and the frequency offset parameter may specify an offset value for each symbol index in the set of symbol indexes. The base station may transmit configuration information to a UE indicating the frequency offset parameter, and the UE may receive the configuration information. The base station may transmit a TRS transmission having a frequency offset corresponding to the frequency offset parameter. The UE may detect the TRS transmission within a frequency band based at least in part on the frequency offset parameter, and perform resource tracking based at least in part on the detected TRS transmission.”: [0007]; “the base station 905 may transmit configuration information indicating the set of burst durations, including the first burst duration and the second burst duration, to a UE 915. In some cases, the base station 905 may allocate a set of TRS resources, including a first TRS resource and a second TRS resource, to the UE 915, wherein the configuration information indicates that each of the set of resources have been allocated to the UE 915. In some cases, the base station 905 may determine a time offset between the first resource and the second resource, wherein the configuration information indicates the time offset. In some cases, the base station 905 may determine a priority order of the first resource relative to the second resource, wherein the configuration information indicates the priority order ”: [0133]; “The configuration information may include a configuration parameter indicating an frequency offset and/or hopping pattern being be used. For example, a bandwidth part may be divided into a set of available TRS bandwidths, and the configuration information may specify a hopping pattern for a TRS burst. The TRS burst may hop from available TRS bandwidth to bandwidth according to the hopping pattern. The configuration information may identify one or more slots and one or more available bandwidths for a TRS transmission. The TRS transmission may include one or more TRS bursts. In the depicted example, three available TRS bandwidths may be defined (e.g., TRS BW 0, 1, and 2). The configuration information may specify that, a TRS transmission is communicated in TRS BW 2 at slot 0, TRS BW 1 at slot 5, and TRS BW 0 at slot 10. The hopping pattern for TRS transmission may repeat every 15 slots until the base station changes the configuration information. The configuration information may define other hopping patterns. In another example, a system bandwidth may be divided into a set of available bandwidth parts, and the configuration information may specify a hopping pattern for a TRS burst. ”: [0130]).

The procedure may further comprise triggering a A-TRS monitoring window based on a group common physical downlink control channel (GC-PDCCH). Hence, a beam specific transmission of the A-TRS may be triggered to one or a plurality of client nodes at a time. The A-TRS monitoring window may be dependent on whether transmission of a P-TRS was validated or not. ”: [[0005]] ; “ At 304, a configuration of at least one A-TRS resource set may be received.

The configuration may comprise, for example, indication of an identifier for detecting the A-TRS triggering command. The configuration may comprise parameters for triggering and defining characteristics of the monitoring window in response to the GC-PDCCH.
”: “ the existence of the monitoring window may be determined, for example, based on a blind detection of the periodic TRS. In an embodiment, the existence of the monitoring window may be determined, for example, based on validation, such as receiving PDCCH/PDSCH to overlap with P-TRS resource, or receiving an SFI or CO-duration validating transmission of P-TRS. If the P-TRS transmission is validated in the latest occasion before the monitoring window, monitoring for GC-PDCCH with A-TRS-RNTI or SFI-RNTI may not be required in a consequent monitoring window.”: [0085]-[0088]; “ The A-TRS monitoring window may be dependent on whether transmission of a P-TRS was validated or not.”: {0005]]),

The QLC assumption may comprise, for example, TypeD RS assumption. In addition, other parameters from the DCI may be determined to enable reception of the A-TRS. The parameters may comprise, for example, a resource set indication, a time domain allocation, a frequency domain allocation, and the like. ”: [0089]).
wherein the availability indication includes an indicator that indicates whether the one or more TRS resource sets are available ( “In an embodiment, the A-TRS triggering command 208 may be configured to provide the client node with an index to the at least one pre-configured A-TRS resource set for tracking configurations. The configuration may provide at least a frequency domain allocation, comprising a starting position and bandwidth, in relation to a common resource grid of the serving cell, symbol positions in the slot, etc. In an embodiment, multiple configurations may be used to trigger multiple A-TRSs transmitted with different TX beams of the network node. GC-PDCCH field may comprise, for example, at least one of a start position in DCI for UE-specific information, 1 bit per configured resource indicating triggering and/or 6-bits per configured resource to carry the SSB-indicator. The GC-PDCCH field may be compressed. ”: [0072]; “ the client node may be configured to determine existence of the monitoring window 206 based on validation. The validation may be based on, for example, receiving PDCCH/PDSCH to overlap with P-TRS resource or receiving an SFI or CO-duration (CO, channel occupancy) validating transmission of the P-TRS. ”{0079]).
Therefore, it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teaching of LIN, NAM to include the above recited limitations as taught by HAKOLA. The suggestion/motivation would be to enable improving both downlink and uplink performance of a system by efficiently providing reference signals for tracking to client nodes (HAKOLA; [0005]).
