AI Technical Summary
The existing technologies face challenges in determining quasi-colocation (QCL) properties and power control assumptions for ordered Physical Random Access Channel (PRACH) transmission in multi-TRP operations, particularly when the Type I Common Search Space is not configured for the CORESETs of a specific CORESETpoolIndex, leading to ambiguity in monitoring random access responses.
The proposed solution involves determining quasi-colocation assumptions (QCL) for receiving downlink control information that schedules a random access response, using indicators in the first DCI to clarify whether the QCL assumption for the second DCI should be the same as the first DCI or a different TCI state, and adjusting power control based on the indicated TCI state or SSB for PRACH transmission.
This approach clarifies QCL properties and power control for PRACH transmission, ensuring accurate monitoring of random access responses even when CORESETpoolIndex configurations are different, enhancing multi-TRP operation efficiency.

[0013]
[13] Some examples of QCL assumptions can be described as follows: A target signal / channel can be received as DMRS from PDCCH / PDCCH. A source signal such as an S SB or CSI-RS or CSI-RS for tracking (TRS) can be used to provide UE QCL assumption(s) for receiving the target signal if the UE can assume that the source and target signals have similar characteristics in at least one of the following parameters: Doppler spread, Doppler shift, time delay, time spread, or beam.
[0014] The source signal can provide UE logic via TCI state. When the UE receives the source signal, the UE determines the above parameters to determine how channel estimation filters and then can receive a target signal such as PDCCH / PDCCH DMRS that applies the determined channel estimation filters and the received beam (if beam domain is applicable, typically only in FR2).

[0018] FIG. 2 illustrates an example of a system diagram that illustrates multi-DCI cross-TRP RACH firing operation both inter-cell and intra-cell;
[0019] FIG. 3 illustrates a set of devices, according to various exemplary modalities. DETAILED DESCRIPTION:
[0020] It will be readily understood that the components of certain exemplary embodiments, as described and illustrated generally in the figures in this document, may be arranged and designed in a wide variety of different configurations. The same reference designation may be used in multiple figures to refer to the same element or function. The following is a detailed description of some exemplary embodiments of non-transient computer program systems, methods, apparatus, and products for performing multiple timing advance (TA) maintenance / operation to facilitate triggered transmission of Petition 870250079646, dated 05 / 09 / 2025, page 58 / 183 7 / 32 Random Access Physical Channel (PRACH) ordered from Downlink Control Physical Channel (PDCCH) in multi-point transmit / receive (TRP) operations.
[0021] Currently, ordered PDCCH-triggered cross-TRP RACH is being considered. Open questions are the QCL properties and / or power control issues associated with PRACH transmission. QCL properties refer to the reception assumption for subsequent messages in a contention-free random access procedure. One of the problems with QCL properties is that the Type I Common Search Space (which is used to monitor PDCCH scheduling RAR in PDSCH) may not be configured for the CORESETs of a specific CORESETpoolIndex. CORESETs under the same CORESETpoolIndex value may sometimes be referred to as TRP(s)). As an example, the CORESETpoolIndex (or TRP) that is the target for PRACH transmission and the target for monitoring the response may not have the search space (type 1 common) configured to monitor the random access response.Random access response is monitored in PDCCH, more specifically in a CORESET(s). The PDCCH provides the second DCI that schedules the RAR (and the RAR may be provided by the PDSCH scheduled by the second DCI) to monitor the response for transmission. In some instances, the CORESETpoolIndex may be referred to as one or more TRPs. In some instances, the CORESETpoolIndex is a value that is associated with a CORESET (control resource set). CORESETs that have the same CORESETpoolIndex value (e.g., 0 or 1) are considered grouped or clustered together. Thus, the CORESETpoolIndex may refer to one or more associated CORESETs. The CORESET(s) is / are used to monitor random access response (e.g., DCI that schedules the random access response). In addition to the QCL rules, the transmission power control assumption for PRACH needs to be determined.
[0022] FIG. 1 illustrates an example of a system diagram that illustrates Petition 870250079646, dated 05 / 09 / 2025, p. 59 / 183 8 / 32 Multi-DCI Cross TRP RACH triggering operation, both inter-cell and intra-cell. Referring to FIG. 1, in step 1, a user equipment (UE) 102 can receive, from a network entity (e.g., TRP 112), a physical downlink control channel (PDCCH) (e.g., space filter / beam 114), which carries first downlink control information (DCI) (see step 1) that includes an indication with settings to trigger or initiate an uplink transmission (e.g., see step 2) of a random access procedure towards at least one target downlink reference signal (DLRS1). In one example, the uplink transmission of a random access can use the target downlink reference signal (DL-RS1) (e.g., indicated in the first DCI that triggers the uplink transmission of a PRACH preamble) as a reference for the UL transmission.In a case of multiple intra-cell TRP operation, either target DL-RS1 or DL-RS2 can be used. In a case of both intra- and inter-cell operations, either DL-RS1 or DL-RS2 can be used. As an example, DL-RS2 can be provided by TRP 112 (referred to by CORESETpoolIndex No. 1) from the same (intra-cell mTRP) or a different PCI (inter-cell mTRP) than that of the service cell.
[0023] The UE 102 can determine a quasi-colocation assumption (QCL) for receiving second downlink control information (DCI) (see step 3 in FIG. 1), which is used to schedule a random access response (RAR) (see step 4) for uplink transmission of the random access procedure (e.g., PRACH preamble UL transmission via 104 spatial filter / beam). Any of the examples in this document are not limited to any specific QCL type assumption. As an example, the QCL assumption may be at least a QCLA type assumption (i.e., without typeD, which may mean that the UE 102 may not use beamforming).
[0024] In one example, the assumptions of QCL, that the types of almost Petition 870250079646, dated 05 / 09 / 2025, page 60 / 183 9 / 32 colocation corresponding to each DL RS are given by the qcl-Type top-layer parameter in QCL-Info and can take one of the following values: 'typeA': {Doppler shift, Doppler spread, mean delay, propagated delay} 'typeB': {Doppler shift, Doppler spread} 'typeC: {Doppler shift, mean delay} 'typeD': {Spatial X-ray parameter}.
[0025] Conventionally, in some exemplary cases, the ordered PDCCH RACH may have the following QCL assumptions: (a) the first DCI format indicating the ordered PDCCH RACH is typically transmitted using the same DL-RS1 as the reference as the target DL-RS for the PRACH transmission (e.g., DL-RS1 -> SSB index); (b) UE 102 determines to estimate the path loss for the UL power control for the RACH transmission based on the DL-RS 1 that is nearly colocalized (QCL'd) with the PDCCH DMRS carrying the PDCCH ORDER (DCI message); (c) the second DCI scheduling the RAR is assumed to be QCL'd with the DCI that triggers the PDCCH order (see step 1 in FIG. 1); and (d) the PDSCH that carries the RAR is QCL'D with the second DCI that schedules the RAR (see step 3 in FIG. 1).If UE 102 attempts to detect DCI 1 0 format with cyclic redundancy check (CRC) scrambled by the corresponding Random Access Radio Network Temporary Identifier (RA-RNTI) in response to a PRACH transmission initiated by a PDCCH order that triggers a contention-free random access procedure for the special cell (SpCell) [11, TS 38.321], UE 102 can assume that the PDCCH that includes the second DCI 1 0 format and the PDCCH order may have the same properties of DM-RS antenna port quasi-colocation.
[0026] With reference to the PDCCH order (see step 1 in FIG. 1), the current problem for cross-triggered TRP firing may include the QCL power ratio / control after PRACH (see step 2) is triggered towards DL-RS 2 since if the UE assumes the response to PRACH transmission to be Petition 870250079646, dated 05 / 09 / 2025, page 61 / 183 10 / 32 is monitored according to the target DL RS of the PRACH transmission (targeted behavior / functionality), but the target CORESETpoolIndex may not be configured with the CORESET associated with the CSS of Typel -PDCCH (common search space). This may mean that UE 102 may not be able to monitor the response for the PRACH transmission consequently in the target CORESETpoolIndex CORESET(s). Also, there is ambiguity about how UE monitors the response when the order is triggered by the first TRP 112 (scheduled in the CORESETpoolIndex#0 CORESET) and the target is DL-RS of CORESETpoolIndex#1 (or vice versa). In other words, UE behavior may not be clear in these situations regarding inheritance rules.
[0027] As shown in FIG. 2, for Multi-TRP operation based on multi-DCI with two timing advance (TA) enhancements, support the case where a PDCCH order (i.e., PDCCH-ordered RACH procedure) sent by TRPx triggers a RACH procedure towards TRPx or TRPy for Multi-DCI both inter-cell and intra-cell. In one example, the development includes considering the PRACH power control details and a determination of PDCCH-ordered QCL, PDCCH RAR (which schedules) or PDSCH RAR.
[0028] In the implementation, there may be two CORESETpoolIndices, 0 and 1, which may be TRP indices (logical indices). If the PDCCH order is coming from a CORESET associated with CORESETpoolIndex 0, then the other index may refer to CORESETpoolIndex 1 (or vice versa).
[0029] In any of the examples in this document, the QCL assumption for the PDCCH may refer to the QCL assumption of the demodulation reference signal (DMRS) of the PDCCH. As an example, when a PDCCH is QCL'd with a DL-RS, the same may refer to the DMRS of the PDCCH that is QCL'd with the DL-RS. In some examples, the DL-RS may be included in a TCI state configuration. Thus, in some examples, the TCI state (or the DL-RS included in the TCI state) may be QCL'd with PDCCH or Petition 870250079646, dated 05 / 09 / 2025, p. 62 / 183 11 / 32 PDSCH (DMRS). In some examples, the DL-RS included in the TCI state configuration can be used as a reference for uplink transmission (e.g., PUCCH / PUSCH). A TCI state can include / comprise a DL-RS that has a first QCL type (e.g., type A) and / or two DL-RSs that have a first QCL type (e.g., type A) and a second DL-RS that has a second QCL type (e.g., type D). If the TCI state has two QCL types, the UE can use the one with QCL type D.
[0030] According to this modality, the first downlink control information may indicate a first value (e.g., = 0) that may cause UE 202 to determine the quasi-colocation assumption for the PDCCH that the second DCI that schedules the random access response to be the same as the first DCI that triggers or initiates the random access procedure.
[0031] For example, in step 1 of FIG. 2, if the downlink control information indicates a first value (e.g., = 0), UE 202 can assume the QCL assumption for the PDCCH (PDCCH DMRS) that carries the second DCI that schedules the random access response to be the same as the PDCCH (DMRS) that was used to transmit the first DCI that triggered the PDCCH order.
[0032] In one example (option 1), if the first downlink control information indicates a second value (e.g., = 1), UE 202 assumes the QCL assumption for the PDCCH carrying the second DCI that schedules the random access response to be the same as the DL RS that was indicated as the target reference signal (RS) for the PRACH transmission (or DL RS associated with the PRACH transmission).
[0033] In another example (option 2), if the first downlink control information (DCI) indicates a second value (e.g., = 1), UE 202 can assume the QCL assumption for the PDCCH carrying the second DCI that schedules the random access response to be the same as the RS of Petition 870250079646, dated 05 / 09 / 2025, page 63 / 183 12 / 32 DL of one of the activated TCI states of the different CORESETpoolIndexes value that was indicated as the target RS for PRACH transmission.
[0034] In the implementation, one of the activated TCI states can include any of: a lower active TCI state identifier in the list of active TCI states, a more recently activated TCI state in the list of active TCI states, or a lower active TCI code point in the list of active TCI states.
[0035] In another example (option 3), downlink control information can indicate whether the first or second indicated TCI state is used as a QCL assumption for the PDCCH (DMRS) that is used to transmit the second DCI that schedules the random access response. In one example, if the random access response follows (i.e., the response is assumed to be transmitted), the indicated TCI state (as a QCL reference) can be configured (e.g., by RRC) and / or indicated in a field in the DCI that triggers the PDCCH order. In one example, if the random access response is configured to be monitored using the indicated TCI state as the assumption for the second DCI that schedules the random access response, the UE can determine the QCL assumption based on the indicated TCI state.
[0036] In another example (option 4), downlink control information can indicate whether the random access response is monitored at the CORESETpoolIndex value that triggered the transmission or at a CORESETpoolIndex that is different from the index that triggered the PDCCH order. CORESETpoolIndex can include one or more CORESETs.
[0037] In any of the above modes, if the first downlink control information indicates a second value (e.g., = 1), the QCL assumption for the PDSCH scheduled by the second DCI for which the QCL assumption is determined as above, may be the same as the QCL assumption determined for PDCCH (DMRS) that is used to schedule the second DCI that schedules the random access response. Petition 870250079646, dated 05 / 09 / 2025, page 64 / 183 13 / 32
[0038] In an additional embodiment, if the downlink control information indicates a second value (e.g., = 1) and the first DCI trigger is scheduled on the CORESET configured with a CORESETpoolIndex value of 0, and UE 202 determines the random access response to be monitored on CORESETs with poolindex#1 (or vice versa). In a further example, if either of the CORESETs (from poollndex#1 or poollndex#0, depending on the indication and which CORESETpoolindex#0 value was used to transmit the first DCI trigger) is not associated with CSS Type1 (search space used to monitor the RAR response), the UE may determine to monitor the random access response using C-RNTI (cellular radio network temporary identifier) (or RA-RNTI) in the UE-specific search space (USS) or Type3-CSS of at least one CORESET ID associated with poolindex#1 (or poollndex#0).
[0039] In a further example, the UE can determine random access response monitoring using C-RNTI (or RA-RNTI) in the USS or Type3CSS of at least one CORESET ID associated with poolindex#1 (or poollndex#0). In a further example, the UE can determine random access response monitoring using C-RNTI (or RA-RNTI) in any CSS configured in at least one CORESET ID associated with CORESETpoolIndex#1 (or poollndex#0). Monitoring can be based on at least any one of: a minor CORESET ID, a CORESET ID (or a minor / major CORESET ID) that follows the indicated unified TCI state, or a CORESET ID (minor / major) that is not associated with the unified TCI state.
[0040] In an additional embodiment, if the information in the first DCI that triggers the PDCCH order indicates a first value, this may indicate that the UE monitors the random access response with the same QCL assumption as the PDCCH (DMRS) that was used to schedule the first triggering DCI. In an exemplary additional embodiment, if the information in the first DCI that triggers the PDCCH order indicates a second value, this may Petition 870250079646, dated 05 / 09 / 2025, page 65 / 183 14 / 32 indicates that the UE monitors the random access response with the QCL assumption of the target DL-RS indicated by the first trigger DCI. In a further exemplary embodiment, if the information in the first trigger DCI indicates a second value, this may indicate that the UE monitors the random access response with the QCL assumption determined by the CORESET of a different CORESETpoolIndex value than was used to transmit the first trigger DCI. The QCL assumption may be indicated by the activated TCI state associated with the different CORESETpoolIndex value of the PDCCH (DMRS) that was used to schedule the first trigger DCI that was used for t (e.g., = 1 or indicates that the UE uses a CORESET of another CORESETpoolIndex for response monitoring).
[0041] In an additional embodiment, if the first downlink control information indicates a second value (e.g., = 1) and the first DCI trigger is scheduled on the CORESET configured with a CORESETpoolIndex value of 0, and the UE determines the response to be monitored on CORESETs with poolIndex#1, and the CORESETs (of poolIndex#1) are not associated with CSS Type1 (search space used to monitor RAR response), the UE may determine the monitoring of the response using C-RNTI (or RA-RNTI) in the USS or Type3-CSS of at least one CORESET ID associated with poolIndex#1. Monitoring may be based on at least any one of: a lower CORESET ID, a CORESET ID (or a lower / higher CORESET ID) that follows the indicated unified TCI state, or a CORESET ID (lower / higher) that is not associated with the unified TCI state. The above approach can also be considered the reverse in terms of the CORESETpoolIndex# value.
[0042] In one embodiment, the interpretation of the first and second values may depend on which CORESET (configured with the CORESETpoolIndex value) the first DCI that triggers the ordered random access procedure of PDCCH is scheduled for. Thus, the interpretation of the information field (which provides the first / second / one of the values) in the first DCI Petition 870250079646, dated 05 / 09 / 2025, page 66 / 183 15 / 32 can be conditionally interpreted or may depend on additional parameters or assumptions. For example, if the CORESET transmitting the PDCCH carrying the first DCI (PDCCH ORDER) is configured with CORESETPoolIndex#0, one of the values (e.g., 1) in the information field might refer to CORESETPoolIndex#1. Thus, UE 202 can interpret the value in the first DCI (PDCCH ORDER) depending on the association of CORESETs to the CORESETpoolIndex. As a further example, the first value might indicate that the UE monitors the random access response (RAR) on the CORESET of the same CORESETpoolIndex that was used to transmit the first DCI (PDCCH order).The second value may indicate that UE 202 monitors the random access response in the CORESET from another / different CORESETpoolIndex that was used to transmit the DCI (PDCCH order).
[0043] In one embodiment, the value and association with the CORESETpoolIndex of the information field can be configurable. As an example, the first value (e.g., 0) is configured to indicate the first value of the CORESETpoolIndex (e.g., 0). In another example, the second value (e.g., 1) is configured to indicate a second value of the CORESETpoolIndex (e.g., 1). In one example, the first value might indicate that UE 202 monitors the random access response in the CORESET of the CORESETpoolindex associated with the value (e.g., 0). The second value might indicate that UE 202 monitors the random access response in the CORESET of the CORESETpoolindex associated with the second value (e.g., 1). Thus, random access response monitoring (and the selection of the CORESETpoolindex to determine the assumptions for random access response monitoring) is determined by UE 202 based on the information field that indicates the CORESETpoolindex value.
[0044] In one modality, a field in the first DCI that triggers access Petition 870250079646, dated 05 / 09 / 2025, p. 67 / 183 A 16 / 32 random sorted PDCCH can indicate whether the UE monitors the RA response in CSS (e.g., using RA-RNTI or C-RNTI) or in USS (using C-RNTI or RA-RNTI).
[0045] In an additional embodiment, if the information indicates a second value (e.g., = 1 or indicates that the UE uses CORESET from another CORESETpoolindex for response monitoring), UE 202 can determine path loss 204 for PRACH power control based on the SSB (or target DL-RS2) associated with the PRACH preamble, if the SSB (or target DL-RS2) is configured as the QCL source for one of the TCI states (e.g., TCI enabled states) or based on the PDCCH DMRS of the indicated TCI state, if the SSB (or target DL-RS2) is the QCL source for the TCI state. The target DL-RS2 can be one from an SSB or CSIRS.
[0046] In one embodiment, UE 202 can determine path loss 204 for PRACH power control based on the SSB (or DL-RS2) included in the indicated TCI state. In one example, UE 202 can base power control on the indicated TCI state for the CORESETPoolIndex value. In another example, UE can base power control on the indicated TCI state (the DL-RS2 included in the TCI State) for the CORESETPoolIndex value when the first DCI carrying the PDCCH order indicates that the random access response is monitored on CORESETs with a CORESETPoolIndex value different from the CORESET used to transmit DCI (PDCCH order).
[0047] In one example, the second value / one of the values indicated by the first DCI (PDCCH order) may indicate that UE 202 monitors the DCI that schedules the random access response in CORESET(s) of a CORESETpoolindex different from the CORESETpoolIndex used to transmit the second DCI that triggered the random access transmission. If the indicated TCI state includes two DL-RS (i.e., DL-RS1, DL-RS2), UE 202 may use the one configured with a QCL-typeD. Petition 870250079646, dated 05 / 09 / 2025, page 68 / 183 17 / 32

Device according to claim 1, characterized in that the first downlink control information indicates the second value that causes the device to determine that the quasi-colocation assumption for the PDCCH carrying the second DCI scheduling the random access response is based on the CORESETpoolIndex value associated with the PDCCH: wherein the first value indicates that the QCL assumption for response monitoring is determined to be at the same CORESETpoolIndex value that was used to trigger the first DCI indicating the RACH, wherein the second value indicates that the QCL assumption for response monitoring is determined to be at the other CORESETpoolIndex value that was used to trigger the DCI indicating the RACH.
8. Device, according to claim 1, characterized in that the first downlink control information indicates the second value that causes the device to determine that the quasi-colocation assumption for the PDCCH carrying the second DCI that schedules the random access response is based on a configuration of whether a common search space type used to monitor the second DCI that schedules the random access response is configured.
9. Device according to claim 1, wherein the device is characterized by being further caused to determine, when the search space type is not configured, the monitoring of the PDCCH that carries the scheduling command for the random access response on at least one of: a minor CORESET ID, a CORESET ID that follows unified TCI state, or a (minor) CORESET ID that is not associated with unified TCI state.

Apparatus, according to claim 1, characterized in that the uplink transmission of the random access procedure comprises the transmission of PRACH preambles associated with at least one target downlink reference signal.
11. A wireless communication method performed by a device characterized by comprising receiving, from a network entity, a physical downlink control channel (PDCCH) carrying first downlink control information (DCI) comprising an indication with settings to trigger or initiate an uplink transmission of a random access procedure towards at least one target downlink reference signal, wherein the first downlink control information indicates a second value that causes the device to determine the quasi-colocation assumption for the PDCCH carrying the second DCI when scheduling the random access response, to be the same as at least one downlink reference signal of a transmission control indicator (TCI) state indicated by a CORESETpoolIndex value.which is different from an index value that was used for the PDCCH which comprises the indication to trigger the uplink transmission of the random access procedure; and determine a quasi-colocation assumption (QCL) for receiving second downlink control information that schedules a random access response (RAR) for the uplink transmission of the random access procedure.
12. Network entity for wireless communication characterized by comprising: at least one processor; and at least one memory that stores instructions that, when executed by at least one processor, cause the device to at least: send, to a user equipment (UE), a physical downlink control channel (PDCCH) carrying first downlink control information (DCI) comprising an indication with settings to trigger or initiate on the UE, an uplink transmission of a random access procedure towards at least one target downlink reference signal transmitted by the device, wherein the indication configures the UE to determine a near-colocation assumption (QCL) for receiving second downlink control information,wherein the first downlink control information indicates a second value that causes the device to determine the quasi-colocation assumption for the PDCCH carrying the second DCI when scheduling the random access response, to be the same as at least one downlink reference signal of a transmission control indicator (TCI) state indicated by a CORESETpoolIndex value, which is different from an index value that was used for the PDCCH comprising the indication to trigger the uplink transmission of the random access procedure; and schedule transmission, of a random access response (RAR) to the UE, based on the second downlink control information, in response to receiving PRACH preambles comprised in the random access procedure transmitted by the UE.
