[0026] The present disclosure provides an information processing method and device.

[0027] In a first aspect, the present disclosure provides an information processing method, which comprises:

[0028] According to a first transmission delay and a second transmission delay between the terminal and the network device, a first round trip time (RTT) between the terminal and the network device is determined, wherein the first transmission delay is associated with a first serving cell where the terminal is located, and the second transmission delay is associated with a second serving cell where the terminal is located.

[0029] In the above embodiment, the RTT between the terminal and the network device is determined according to the transmission delays of different carriers. Thus, the accuracy and reliability of the determined RTT in the carrier aggregation scenario are improved.

[0030] In some embodiments of the first aspect, the method further comprises:

[0031] determining a delay parameter between an uplink reference point associated with each serving cell and the network device;

[0032] determining an uplink timing advance (TA) of the terminal in each serving cell;

[0033] determining a transmission delay associated with each serving cell according to the delay parameter of the serving cell and the TA of the terminal in the serving cell.

[0034] In the above embodiment, the transmission delay associated with each serving cell is determined according to the delay parameter of the serving cell and the TA of the terminal in the serving cell. Thus, the accuracy and reliability of the determined transmission delay associated with each serving cell are ensured.

[0035] In some embodiments of the first aspect, the method further comprises:

[0036] sending an uplink transmission through the first serving cell, or receiving an uplink scheduling for the first serving cell;

[0037] delaying the first RTT time, and then starting to monitor a downlink channel of the second serving cell.

[0038] In the above embodiment, if the terminal receives and sends through the serving cells associated with different transmission delays, the monitoring occasion can be controlled based on the corresponding RTT in this scenario. Thus, the transmission reliability is improved, the power consumption of the terminal is saved, and resource waste is avoided.

[0039] In some embodiments of the first aspect, in some embodiments, the orbit height of the satellite to which the first serving cell belongs is less than the orbit height of the satellite to which the second serving cell belongs.

[0040] In the above embodiments, the uplink transmission is performed by using the serving cell covered by the low-orbit satellite, and the downlink transmission is received by using the serving cell covered by the high-orbit satellite, thereby ensuring the reliability of the transmission in the mobile scenario.

[0041] In some embodiments of the first aspect, in some embodiments, the method further comprises at least one of:

[0042] The timing value of a first uplink discontinuous reception (DRX) hybrid automatic repeat request (HARQ) round trip time (RTT) timer of the first serving cell is extended by the first RTT time.

[0043] The timing value of a second uplink DRX HARQ RTT timer of the second serving cell is extended by the first RTT time.

[0044] In the above embodiments, the terminal receives and transmits by associating different transmission latency serving cells, and then the timing value of the DRX HARQ timer is extended based on the corresponding RTT in this scenario, thereby providing conditions for the reliable reception of the downlink scheduling or the downlink transmission.

[0045] In some embodiments of the first aspect, in some embodiments, the above method further comprises:

[0046] After receiving the uplink scheduling or transmitting the uplink transmission, the timing value of the first uplink DRX HARQ RTT timer of the first serving cell and the timing value of the second uplink DRX HARQ RTT timer of the second serving cell are determined based on at least one of:

[0047] The uplink scheduling or the uplink transmission is associated with the first serving cell, the timing value of the first uplink DRX HARQ RTT timer corresponding to the first serving cell is determined as a first configured time length, and the timing value of the second uplink DRX HARQ RTT timer corresponding to the second serving cell is extended by the first RTT time.

[0048] The uplink scheduling or the uplink transmission is associated with the second serving cell, the timing value of the second uplink DRX HARQ RTT timer corresponding to the second serving cell is determined as a second configured time length, and the timing value of the first uplink DRX HARQ RTT timer corresponding to the first serving cell is extended by the first RTT time.

[0049] In the above embodiments, when the terminal receives and transmits through the association of different transmission delay service cells, the terminal can determine the timing value of the uplink DRX HARQ RTT timer of different service cells based on the service cells used for transmission and reception respectively. Thus, unnecessary monitoring is avoided and the power consumption of the terminal is saved on the basis of ensuring reliable reception of the terminal.

[0050] In some embodiments of the first aspect, the method further comprises:

[0051] After receiving the uplink scheduling or transmitting the uplink transmission, the timing value of the first uplink DRX HARQ RTT timer of the first service cell and / or the timing value of the second uplink DRX HARQ RTT timer of the second service cell are extended by a first time length.

[0052] The first time length is the smaller one of a second RTT and a third RTT, the second RTT is a corresponding round trip delay when receiving downlink transmission through the first service cell, and the third RTT is a corresponding round trip delay when receiving downlink transmission through the second service cell.

[0053] In the above embodiments, when the terminal receives and transmits through the association of different transmission delay service cells, the timing value of the uplink DRX HARQ RTT timer of different service cells is extended by a relatively small time value, so that the success rate and reliability of transmission are improved at a low power consumption cost.

[0056] The second uplink DRX HARQ RTT timer expires, and a second DRX retransmission timer of the second service cell is started.

[0060] In the above embodiments, when the terminal transmits the uplink feedback for the downlink scheduling of the first serving cell through the second serving cell, the terminal can extend the timing value of the first downlink DRX HARQ RTT timer and / or the timing value of the second downlink DRX HARQ RTT timer by the first RTT time after the uplink feedback. Thus, the duration of the terminal waiting for the downlink retransmission scheduling is extended, and the probability of the terminal receiving the downlink retransmission scheduling is improved.

The CU-DU structure can split the protocol layers of the access network device, and part of the functions of the protocol layers are controlled by the CU, and the remaining part or all of the functions of the protocol layers are distributed in the DU and controlled by the CU, but the present disclosure is not limited thereto.

[0123] It can be understood that the communication system described in the embodiments of the present disclosure is for more clearly illustrating the technical solutions of the embodiments of the present disclosure, and does not constitute a limitation on the technical solutions proposed in the embodiments of the present disclosure. It can be known by those skilled in the art that, with the evolution of system architecture and the appearance of new business scenarios, the technical solutions proposed in the embodiments of the present disclosure are also applicable to similar technical problems.

[0124] The following embodiments of the present disclosure can be applied to the communication system 100 shown in FIG. 1A or part of the subjects, but are not limited thereto. The subjects shown in FIG. 1A are illustrative, and the communication system can include all or part of the subjects in FIG. 1A, or other subjects other than those in FIG. 1A. The number and form of each subject is arbitrary, each subject can be physical or virtual, the connection relationship between each subject is illustrative, each subject can not be connected or can be connected, the connection can be in any way, can be direct connection or indirect connection, can be wired connection or wireless connection.

[0125] Embodiments of the present disclosure can be applied to a Non-terrestrial Network (NTN), Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (Bluetooth (registered trademark)), Public Land Mobile Network (PLMN) network, Device-to-Device (D2D) system, Machine to Machine (M2M) system, Internet of Things (IoT) system, Narrow Band-IoT (NB-IoT) system, Vehicle-to-Everything (V2X), system using other communication methods, next-generation system expanded based on them, and the like. Further, a plurality of systems can be combined (for example, combination of LTE or LTE-A and 5G, and the like).

[0126] In some embodiments, different ways of processing signals by the satellite can be divided into a transparent mode and a regenerative mode. In the transparent mode, the NTN ground station sends the signal of the gNB to the satellite, and the satellite sends the signal to the UE through the satellite frequency band after converting the signal to the satellite frequency band. Except for frequency conversion and signal amplification, the satellite does not demodulate the gNB signal, which is similar to a repeater. In the regenerative mode, the NTN ground station sends the signal of the gNB to the satellite, and the satellite first demodulates and decodes the signal and then re-encodes and modulates the signal (this process is regeneration) and sends the regenerated signal through the satellite frequency band.

[0127] FIG. 1B is a schematic diagram of a carrier aggregation scenario of an NTN.

[0128] As shown in FIG. 1B, in the NTN carrier aggregation scenario, a primary cell (PCell) can use a satellite 1 (such as a high-orbit satellite) to provide large coverage, and other secondary cells (SCells) except for a special cell (SpCell) can use a satellite 2 (such as a low-orbit satellite) to provide high speed. The PCell and the SCell perform carrier aggregation through the satellite transparent mode, that is, the NTN ground station can send the signal of the gNB to the satellite 1 and the satellite 2 through the transparent mode. The SpCell refers to the PCell and a primary secondary cell (PSCell).

[0129] For such a scenario, the propagation delay of data sent through different carriers is different. Moreover, there is a scenario in which the terminal sends through one carrier but receives through another carrier. For example, for random access (RA) initiated on the SCell, Msg1 and / or MsgA of the random access are sent on the SCell, but the random access response is received on the PCell. At this time, the round-trip time (RTT) of the UE to the gNB is all different from the transmission and reception through one carrier.

[0130] In the related art, if only one carrier is considered, the RTT of the UE-gNB can be defined as T+K mac . Wherein T represents the RTT between the UE and the uplink reference point, and Kmac represents the RTT from the uplink reference point to the base station. When sending through one carrier but receiving through another carrier, the RTT of the UE-gNB needs to be calculated according to the transmission delay of the two carriers respectively.

[0131] The information processing method and device provided by the present disclosure will be described in detail below with reference to the accompanying drawings.

[0132] FIG. 2A is an interaction diagram of an information processing method according to an embodiment of the present disclosure. As shown in FIG. 2A, the embodiment of the present disclosure relates to an information processing method, which comprises:

[0133] In step S2101, the terminal 101 and the network device 102 determine the time delay parameter between the uplink reference point associated with each serving cell and the network device.

[0134] In some embodiments, the terminal 101 is a non-terrestrial network (NTN) terminal, and the network device is an NTN device.

[0135] In some embodiments, the terms “non-terrestrial network”, “non-terrestrial network”, “non-terrestrial communication”, “non-terrestrial communication” and the like can be replaced with each other.

[0136] In some embodiments, the terminal 101 transmits through the carrier of one serving cell and receives through the carrier of another serving cell.

[0137] In some embodiments, the two carriers used by the terminal for receiving and transmitting can work in a carrier aggregation manner and through a satellite transparent transmission mode or a regeneration mode.

[0138] In some embodiments, the two carriers provided by the two serving cells can be used for uplink transmission and downlink transmission, respectively.

[0139] In some embodiments, the two serving cells can be transmitted through different satellites. The two satellites can be satellites of different orbital heights, or satellites of the same orbital height but different RTTs.

[0140] In some embodiments, the “uplink reference point” can be a reference position of the serving cell within the satellite coverage range where the terminal is located.

[0141] In some embodiments, the time delay parameter between the uplink reference point and the network device can be determined according to a protocol or sent by the network device 102 to the terminal 101, which is not limited in the present disclosure.

[0142] In some embodiments, the network device 102 can send the time delay parameter to the terminal 101 through a system message.

[0143] In some embodiments, the network device 102 can send the time delay parameter to the terminal 101 through a downlink transmission specially configured for configuring the time delay parameter.

[0144] In step S2102, the terminal 101 and the network device 102 determine the uplink TA of the terminal in each serving cell.

[0145] In some embodiments, in order to ensure that the uplink signals of all terminals can be correctly aligned at the network device, the network device estimates the transmission delay between the terminal and the network device according to the distance between the terminal and the network device, and calculates a timing advance (TA), and then notifies the terminal through a timing advance command (TAC).

[0146] In some embodiments, the steps S2101 and S2102 can be performed simultaneously, or S2102 can be performed first and then S2101, and the present disclosure does not limit this.

[0147] In step S2103, the terminal 101 and the network device 102 determine the transmission delay associated with each serving cell according to the delay parameter and the TA.

[0148] In some embodiments, the terms “transmission delay”, “propagation delay”, “transmission delay time”, “propagation delay time” and the like can be replaced with each other in some cases.

[0149] In some embodiments, the terminal 101 and the network device 102 can determine the round-trip delay between the terminal 101 and the network device 102 in the serving cell according to the delay parameter and the TA.

[0150] In some embodiments, the round-trip delay between the terminal 101 and the network device 102 = the delay parameter + the TA.

[0151] In some embodiments, the transmission delay associated with the serving cell can be half of the round-trip delay between the terminal 101 and the network device 102.

[0152] In step S2104, the terminal 101 and the network device 102 determine the first round-trip delay RTT according to the first transmission delay and the second transmission delay.

[0153] In some embodiments, the first transmission delay is associated with the first serving cell in which the terminal is located. That is, the first transmission delay is associated with the first carrier of the first serving cell.

[0154] In some embodiments, the second transmission delay is associated with the second serving cell in which the terminal is located. That is, the second transmission delay is associated with the second carrier of the second serving cell.

[0155] In some embodiments, the sum of the first transmission delay and the second transmission delay can be determined as the first round-trip delay (UE-gNB RTT) between the terminal and the network device.

[0156] In some embodiments, the first serving cell can be a PCell or an SCell, and the corresponding second serving cell can be an SCell or a PCell.

[0157] In some embodiments, the terminal 101 receives (or transmits) and transmits (or receives) through the first serving cell and the second serving cell respectively, and the first RTT between the terminal 101 and the network device 102 can be the sum of the first transmission delay and the second transmission delay.

[0158] In step S2105, the terminal 101 transmits the uplink transmission through the first serving cell.

[0159] In step S2106, the terminal 101 starts to monitor the downlink channel of the second serving cell after delaying for the first RTT.

[0160] In some embodiments, the uplink transmission can be a first message of random access.

[0161] In some embodiments, the first message (Message, Msg) of random access can be Msg1 or MsgA.

[0162] In some embodiments, the uplink transmission can also be a scheduling request (Scheduling Request, SR).

[0163] In some embodiments, the uplink transmission can also be a media access control (media access control, MAC) control element (control Element, CE).

[0164] In some embodiments, the terminal 101 can transmit the uplink transmission by using a configured grant (Configured Grant, CG) resource.

[0165] In some embodiments, the first serving cell can be a cell covered by a low earth orbit (Low-Earth Orbit, LEO) satellite.

[0166] In some embodiments, the terms “low orbit”, “near earth orbit”, “near ground orbit”, “low earth orbit” and the like can be replaced with each other.

[0167] In the embodiments of the present disclosure, since the low orbit satellite has a relatively low height above the ground, it can provide a higher rate of transmission service and a relatively low transmission delay. In order to minimize the delay time of the uplink transmission, the terminal 101 can transmit the uplink transmission through the first serving cell.

[0168] In some embodiments, the orbit height of the satellite to which the first serving cell belongs is less than the orbit height of the satellite to which the second serving cell belongs.

[0169] That is, the transmission delay of the first serving cell is less than the transmission delay of the second serving cell.

[0170] In some embodiments, the second serving cell can be a cell covered by a medium-high orbit satellite.

[0171] In some embodiments, the high orbit can be a Geostationary Earth Orbit (GEO).

[0172] In some embodiments, since the terminal 101 can be in a moving state, and the coverage of the second serving cell is larger than that of the first serving cell, in order to ensure that the terminal 101 can reliably receive the downlink transmission, the terminal 101 can receive the downlink transmission by monitoring the downlink channel of the second serving cell.

[0173] In some embodiments, in order to avoid the terminal 101 monitoring the downlink channel of the second serving cell too early and wasting resources, the terminal 101 can delay the first RTT time after sending the uplink transmission through the first serving cell (or receiving the uplink scheduling for the first serving cell), and then monitor the downlink channel of the second serving cell.

[0174] In some embodiments, the downlink channel can be a Physical Downlink Control Channel (PDCCH) or a Physical Downlink Shared Channel (PDSCH).

[0175] In some embodiments, the uplink transmission is Msg1 or MsgA, and the terminal 101 can delay the first RTT time and then start the Random Access Response (RAR) window corresponding to the second serving cell.

[0176] In some embodiments, the terminal 101 can delay the first RTT time after the first symbol position of the earliest resource after sending the random access preamble, and then start the RAR window corresponding to the second serving cell.

[0177] In some embodiments, the earliest resource is a Physical Downlink Control Channel (PDCCH) resource.

[0178] In some embodiments, the terminal 101 can determine the earliest PDCCH resource according to a control resource set (CORESET).

[0179] In some embodiments, when the uplink transmission is SR, the terminal 101 can delay the first RTT time after sending the SR on the PUCCH of the first serving cell (e.g., SCell) and then monitor the PDCCH of the second serving cell (e.g., PCell).

[0180] In some embodiments, the terminal 101 can also delay the first RTT time after receiving the uplink scheduling for the first serving cell and then start monitoring the downlink channel of the second serving cell.

[0181] In step S2107, the timing value of the first uplink DRX HARQ RTT timer and / or the timing value of the second uplink DRX HARQ RTT timer is extended.

[0182] In some embodiments, the terminal 101 and the network device 101 can extend the timing value of the first DRX HARQ RTT timer and / or the timing value of the second uplink DRX HARQ RTT timer by the first RTT time.

[0183] In some embodiments, since the terminal 101 sends and receives through different serving cells, and the transmission delays associated with different serving cells are different, the terminal 101 and the network device 102 need to extend the timing value of the first (and / or second) uplink DRX HARQ RTT timer based on the determined first RTT at this time. In order for the terminal 101 to monitor the possible uplink retransmission scheduling within the first (and / or second) uplink DRX HARQ RTT timer.

[0184] Correspondingly, if the network device 102 sends a downlink transmission to the terminal 101 through the second serving cell after receiving the uplink transmission sent by the terminal 101 through the first serving cell, the network device 102 can extend the timing value of the first uplink DRX HARQ RTT timer and / or the second DRX HARQ RTT timer by the first RTT time based on the configured value, respectively.

[0185] In some embodiments, the terminal 101 can determine the timing value of the first DRX HARQ RTT timer and the timing value of the second DRX HARQ RTT timer, respectively, after receiving the uplink scheduling for any serving cell or sending the uplink transmission through any serving cell.

[0186] In some embodiments, if the uplink scheduling or uplink transmission is associated with the first serving cell, the terminal 101 can only extend the timing value of the second DRX HARQ RTT timer of the second serving cell by the first RTT time. The timing value of the first DRX HARQ RTT timer of the first serving cell can remain unchanged for the first configured time length.

[0187] In some embodiments, the first configured time length is the timing value configured by the network device 102 for the first DRX HARQ RTT timer.

[0188] In some embodiments, if the uplink scheduling or uplink transmission is associated with the second serving cell, the terminal 101 can only extend the timing value of the first DRX HARQ RTT timer of the first serving cell by the first RTT time. The timing value of the second DRX HARQ RTT timer of the second serving cell can remain unchanged for the second configured time length.

[0189] In some embodiments, the second configured time length is the timing value configured by the network device 102 for the second DRX HARQ RTT timer.

[0190] In some embodiments, after the terminal receives the uplink scheduling or sends the uplink transmission, the terminal can extend the timing value of the first DRX HARQ RTT timer of the first serving cell and / or the timing value of the second uplink DRX HARQ RTT timer of the second serving cell by the first time length, respectively.

[0191] In some embodiments, the first time length is the smaller value (min) of the second RTT and the third RTT, the second RTT is the corresponding round-trip delay when receiving downlink transmission through the first serving cell, and the third RTT is the corresponding round-trip delay when receiving downlink transmission through the second serving cell.

[0192] In some embodiments, the second RTT = uplink transmission delay + delay of receiving downlink transmission by the PCell.

[0193] In some embodiments, the third RTT = uplink transmission delay + delay of receiving downlink transmission by the SCell.

[0194] In some embodiments, the "uplink transmission delay" in the above-mentioned second RTT and third RTT can be the delay when sending uplink transmission by the PCell, or the delay when sending uplink transmission by the SCell.

[0195] For example, the terminal monitors PDCCH on the PCell and the SCell, and after receiving uplink scheduling or sending PUSCH on the CG resource, the duration of the (first and / or second) uplink DRX HARQ RTT timer can be set to be the first duration extended on the basis of the configured duration.

[0196] In the embodiments of the present disclosure, the timing value of the first uplink DRX HARQ RTT timer and / or the second uplink DRX HARQ RTT timer is extended based on the smaller one of the second RTT and the third RTT, so as to shorten the duration of the terminal monitoring the downlink channel as much as possible on the basis of ensuring that the terminal reliably receives the downlink transmission, and reduce the terminal loss.

[0197] In step S2108, the uplink DRX HARQ RTT timer expires, and the DRX retransmission timer is started.

[0198] In some embodiments, after the uplink DRX HARQ RTT timer expires, because the terminal 101 does not know whether the network device 102 successfully decodes the uplink transmission, the drx Retransmission Timer can be started to continue to monitor possible uplink retransmission scheduling after the uplink DRX HARQ RTT timer expires, thereby providing conditions for further providing the success rate and reliability of the uplink transmission.

[0199] In some embodiments, the first DRX retransmission timer of the first serving cell can be started after the first uplink DRX HARQ RTT timer expires.

[0200] In some embodiments, the second DRX retransmission timer of the second serving cell can be started after the second uplink DRX HARQ RTT timer expires. The communication method related to the embodiments of the present disclosure can include at least one of steps S2101-S2108. For example, step S2104 can be implemented as an independent embodiment, steps S2105+S2106 can be implemented as an independent embodiment, steps S2105+S2106+S2107 can be implemented as an independent embodiment, steps S2105+S2107+S2108 can be implemented as an independent embodiment, and the like, but are not limited thereto.

[0201] In the present embodiment or embodiment, each step can be independent, arbitrarily combined or exchanged in order, the optional mode or optional example can be arbitrarily combined, and can be arbitrarily combined with any step of other embodiments or other embodiments.

[0202] FIG. 2B is an interaction diagram of an information processing method according to an embodiment of the present disclosure. As shown in FIG. 2B, the embodiment of the present disclosure relates to an information processing method, and the method comprises:

[0203] In step S2201, the terminal 101 and the network device 102 determine a time delay parameter between an uplink reference point associated with each serving cell and the network device.

[0204] In step S2202, the terminal 101 and the network device 102 determine an uplink TA of the terminal in each serving cell.

[0205] In step S2203, the terminal 101 and the network device 102 determine a transmission time delay associated with each serving cell according to the time delay parameter and the TA.

[0208] In step S2205, the timing value of the first downlink DRX HARQ RTT timer and / or the timing value of the second DRX HARQ RTT timer are extended by the first RTT time for transmitting uplink feedback of downlink scheduling of the first serving cell through the second serving cell.

[0209] In some embodiments, the first serving cell can be a PCell or an SCell, and the corresponding second serving cell can be an SCell or a PCell.

[0210] In some embodiments, after the terminal 101 receives downlink scheduling of one serving cell, the terminal 101 can need to perform uplink feedback through the second serving cell. Since the uplink carrier and the corresponding downlink carrier are transmitted by different satellites, the timing value of the downlink DRX HARQ RTT timer can be extended by the first RTT time. Thus, it is ensured that the terminal can receive downlink transmission within the monitoring period of the downlink channel, which provides a condition for improving the probability of receiving downlink transmission by the terminal.

[0211] In some embodiments, the first downlink DRX HARQ RTT timer is associated with the first serving cell.

[0212] In some embodiments, the second downlink DRX HARQ RTT timer is associated with the second serving cell.

[0213] In some embodiments, the terminal 101 can start a downlink DRX HARQ RTT timer after sending the HARQ feedback through the second serving cell.

[0214] In some embodiments, if the terminal 101 fails to decode the downlink data after the downlink DRX HARQ RTT timer expires, the terminal can start a downlink DRX RetransmissionTimer to listen to possible downlink retransmission data.

[0215] The communication method related to the embodiments of the present disclosure can include at least one of steps S2201-S2205. For example, step S2204 can be implemented as an independent embodiment, steps S2204+S2205 can be implemented as an independent embodiment, steps S2201+S2202+S2203 can be implemented as an independent embodiment, and the like, but are not limited thereto.

[0314] If the terminal transmits through one carrier but receives through another carrier, the round trip time from the UE to the base station is the sum of the signal one-way propagation time of the UE transmitting a signal through the transmitting carrier to the gNB and the signal one-way propagation time of the UE receiving a signal from the gNB through the receiving carrier.

[0315] Optionally, the terminal is an NTN terminal, and the network is an NTN network.

[0320] Optionally, Kmac represents the round-trip delay between the uplink reference point of the satellite and the base station, which is provided by system message or dedicated signaling. UE TA is the uplink timing advance of the UE in the serving cell.

[0322] Optionally, the response window starting time is the first symbol position of the earliest PDCCH resource (i.e. CORESET) after the UE finishes sending PRACH + UE-gNB RTT start.

[0323] Optionally, after the UE sends SR on PUCCH of SCell, the UE monitors PDCCH of PCell. The monitoring occasion is delayed by UE-gNB RTT time. The UE-gNB RTT is calculated in the above manner.
