[0157] Figure 1 This is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.

[0158] like Figure 1 As shown, the communication system 100 includes a terminal 101 and a network device 102.

[0159] In some embodiments, terminal 101 includes, but is not limited to, at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, and wireless terminal device in smart home.

[0160] In some embodiments, network device 102 may include at least one of access network device and core network device.

[0161] In some embodiments, the access network device is, for example, a node or device that connects a terminal to a wireless network. The access network device may include, but is not limited to, at least one of the following in a 5G communication system: evolved Node B (eNB), next-generation eNB (ng-eNB), next-generation Node B (gNB), node B (NB), home node B (HNB), home evolved node B (HeNB), wireless backhaul device, radio network controller (RNC), base station controller (BSC), base transceiver station (BTS), base band unit (BBU), mobile switching center, base station in a 6G communication system, open RAN, cloud RAN, base station in other communication systems, and access node in a wireless fidelity (WiFi) system.

[0162] In some embodiments, the technical solutions of this disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0163] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0164] In some embodiments, a core network device may be a single device comprising one or more network elements, or it may be multiple devices or a group of devices, each comprising all or part of one or more network elements. Network elements may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), or a Next Generation Core (NGC).

[0165] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions provided in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in this disclosure are also applicable to similar technical problems.

[0166] The following embodiments of this disclosure can be applied to Figure 1 The communication system 100 shown, or a part thereof, but not limited to it. Figure 1 The entities shown are illustrative; a communication system may include... Figure 1 All or part of the main body, or may include Figure 1 Other entities besides the main body, the number and form of each entity are arbitrary, the connection relationship between the entities is illustrative, the entities may not be connected or may be connected, and the connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0167] The embodiments disclosed herein can be applied to 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), Futuregeneration radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0168] In this embodiment of the disclosure, the activation of a Single Unified TCI state includes two types: unknown and known. For the switching of the unified TCI state in a multi-TRP (mTRP), two unified TCI states will be activated. These two unified TCI states can have multiple possible combinations, such as one being a known TCI state and the other an unknown TCI state. When the reference signal (RS) used for activation of the known TCI state overlaps with the reference signal used for activation of the unknown TCI state in the time domain, the terminal 101 cannot process the two signals simultaneously due to the time division multiplexing (testing data management, TDM) mechanism.

[0169] In this embodiment of the disclosure, unified TCI state activation includes both downlink (DL) TCI state activation and uplink (UL) TCI state activation. Only after terminal 101 has completed DL TCI state activation can it receive downlink channels with the new TCI state, such as the physical downlink shared channel (PDSCH); and only after terminal 101 has completed UL TCI state activation can it transmit uplink channels with the new TCI state, such as the physical uplink shared channel (PUSCH). In mTRP, when the reference signal used for DL ​​TCI state activation and the reference signal used for UL TCI state activation have a time-domain conflict, terminal 101 cannot process them simultaneously.

[0170] Figure 2a This is an interactive schematic diagram illustrating a method for activating the Transmission Configuration Indicator (TCI) state according to an embodiment of this disclosure. Figure 2a As shown, this disclosure relates to a method for processing TCI state activation, the method comprising:

[0171] In step S2101, network device 102 sends configuration information to terminal 101.

[0172] In some embodiments, network device 102 may send the configuration information via radio resource control (RRC).

[0173] Optionally, different unified TCI states can be configured in this configuration information. After RRC configuration, network device 102 can send an activation command to indicate the TCI state to be updated or activated, i.e., the target TCI state, via downlink control information (DCI) or media access control control element (MAC CE). After activation, terminal 101 can switch TCI states according to the instructions of network device 102.

[0174] Optionally, this configuration information can also configure the unified TCI state as a joint TCI state or a separate TCI state. In the mTRP scenario, beam indication or TCI state indication is more complex.

[0175] In some embodiments, terminal 101 receives the configuration information.

[0176] In step S2102, network device 102 sends a downlink reference signal to terminal 101.

[0177] In some embodiments, the downlink reference signal includes, but is not limited to, a first RS and / or a second RS.

[0178] Optionally, the first RS is used to activate the first TCI state in the unified TCI state; the second RS is used to activate the second TCI state in the unified TCI state.

[0179] In some embodiments, the first TCI state is an unknown TCI state, and the second TCI state is a known TCI state.

[0180] In one example, for the first TCI state, i.e., the unknown TCI state, terminal 101 needs to perform additional receive beam sweeping (RX beam sweeping) based on multiple first RSs.

[0181] Optionally, in the mTRP scenario, the first RS is the RS sent by the first TRP (TRP1) for receiving beam scanning during the first TCI state activation.

[0182] Optionally, the first RS can be a synchronization signal / physical broadcast channel block (SSB) or a channel-state-information reference signal (CSI-RS).

[0183] In another example, for the second TCI state, i.e. the known TCI state, if the TCI state is not in the active TCI state list of PDSCH, the terminal 101 needs an additional second RS to obtain the time / frequency (T / F) of the target TCI state, i.e. to perform time / frequency tracking (T / F tracking).

[0184] Optionally, the second RS can be an SSB.

[0185] Optionally, in the mTRP scenario, the second RS is the RS sent by the second TRP (TRP2) for time-frequency tracking during the second TCI state activation.

[0186] In some embodiments, when the SSB used for T / F tracking and the SSB used for receiving beam scanning have a time-domain conflict, in the TDM mechanism, the terminal 101 can only receive RS from one direction at a time. In the case of mTRP, the delay time for TCI state activation will be extended compared to related technologies.

[0187] Optionally, the delay time is used to indicate the time it takes for terminal 101 to complete the TCI state switch according to the TCI state activation indication of network device 102.

[0188] In step S2103, there is a time domain conflict between the first RS and the second RS, and the terminal 101 prioritizes receiving the first RS (e.g., the RS used to receive beam scanning).

[0189] Optionally, when the first RS, i.e. the first TCI state (unknown TCI state), is active, TRP1 sends an RS for receiving beam scanning.

[0190] Optionally, terminal 101 receives the first first RS, such as the first SSB, from TRP1 for receiving beam scanning.

[0191] Optionally, during the receive beam scanning process, terminal 101 needs to perform layer reference signal received power (L1-RSRP) measurement to determine the optimal beam. For example, terminal 101 receives the first SSB from TRP1 to perform L1-RSRP measurement.

[0192] In some embodiments, the time-domain conflict between the first RS and the second RS includes one of the following:

[0193] The first RS and the second RS have the same period and the same offset;

[0194] The first RS and the second RS have different periods but the same offset.

[0195] Optionally, refer to Figure 2e As shown, taking the first RS as an SSB transmitted by TRP1 and the second RS as an SSB transmitted by TRP2 as an example, the first RS and the second RS have the same period and the same offset, that is, the two SSBs are fully overlapped in the time domain.

[0196] Optionally, referring to Figure 2, the example is still taken with the first RS being an SSB sent by TRP1 and the second RS being an SSB sent by TRP2. The first RS and the second RS have different periods but the same offset, that is, the two SSBs partially overlap in the time domain.

[0197] In step S2104, terminal 101 determines the delay time for unified TCI state activation based on the first interval and RS processing time.

[0198] In some embodiments, the first interval is the interval between the terminal 101 performing a receive beam scan based on the first RS and the first second RS.

[0199] Optionally, refer to Figure 2e As shown, taking the SSB sent by TRP1 as the first RS and the SSB sent by TRP2 as the second RS as the second RS, T first-SSB2 This is the first interval.

[0200] In some embodiments, terminal 101 first receives the SSB sent by the first RS, such as the receive beam scan, and performs L1-RSRP measurement. For the SSB used for L1-RSRP measurement, terminal 101 needs to spend 8 SSBs for receive beam scan. After these 8 SSBs, terminal 101 performs T / F tracking on TRP2, so the delay time will include the L1-RSRP measurement period and one SSB period.

[0201] In some embodiments, the total delay t1 satisfies:

[0202]

[0203] Where n represents the time when the terminal receives the unified TCI status activation command, and T HARQ T represents the time between downlink transmission and the corresponding terminal sending an acknowledgment feedback message. L1-RSRP1 T represents the time used for L1-RSRP1 measurement during beam scanning. first-SSB1T represents the time elapsed between the terminal receiving the activation command and the first RS. SSB-proc T is the RS processing time. first-SSB2 For the first interval, TO uk1 with TO k2 It is a constant.

[0204] Alternatively, the activation command can be the DCI or MAC CE of the aforementioned embodiments.

[0205] Optionally, you may refer to Figure 2e The T shown first-SSB1 .

[0206] Optionally, when RS is SSB, T SSB-proc It can be 2ms.

[0207] Optionally, To handle the latency of activation signaling such as MAC CE (e.g., demodulation).

[0208] Optionally, TO uk1 It can be equal to 0 or 1, TO k2 It can be equal to 0 or 1.

[0209] Optionally, the above-mentioned delay time t1 applies to Figure 2e and 2f For two time-domain conflict scenarios, the delay time can be the maximum delay for known TCI state activation and unknown TCI state activation.

[0210] Optionally, if CSI-RS is used for L1-RSRP measurement of TRP 1, the above-mentioned delay time can be referenced when the CSI-RS of L1-RSRP overlaps with the SSB used for T / F tracking.

[0223] Figure 2b This is an interactive schematic diagram illustrating a method for activating the Transmission Configuration Indicator (TCI) state according to an embodiment of this disclosure. Figure 2b As shown, this disclosure relates to a method for processing TCI state activation, the method comprising:

[0224] In step S2201, network device 102 sends configuration information to terminal 101.

[0225] Optionally, alternative implementations of step S2201 can be found in [reference needed]. Figure 2a intermediate step S2101 and Figure 2a Other related parts in the embodiments involved will not be described in detail here.

[0226] In step S2202, network device 102 sends a downlink reference signal to terminal 101.

[0227] Optionally, alternative implementations of step S2202 can be found in [reference needed]. Figure 2a intermediate step S2102 and Figure 2a Other related parts in the embodiments involved will not be described in detail here.

[0228] In step S2203, there is a time domain conflict between the first RS and the second RS, and the terminal 101 prioritizes receiving the second RS (e.g., the RS used for T / F tracking).

[0229] Optionally, in the second RS, i.e. the second TCI state (known TCI state) is active, TRP2 sends an RS for time-frequency tracking.

[0230] Optionally, when terminal 101 receives the first second RS from TRP2, such as the first SSB, it first activates T / F tracking for the TCI state of TRP2.

[0231] In some embodiments, the conflict scenario between the first RS and the second RS can be referred to the optional implementation of step S2103, or referred to Figure 2e and 2f As shown.

[0232] In step S2204, terminal 101 determines the delay time for unified TCI state activation based on the first cycle and RS processing time.

[0233] In some embodiments, the first period is the period of the first RS.

[0234] Optionally, when the first RS is activated in an unknown TCI state, the corresponding SSB is activated, and the first period is the period of that SSB, such as... Figure 2f T in SSB1 .

[0235] In some embodiments, terminal 101 first receives the second RS such as the SSB of TRP2 for T / F tracking. Terminal 101 will need an additional SSB for L1-RSRP measurement of TRP1.

[0236] In some embodiments, the delay time t2 satisfies:

[0237]

[0238] Where n represents the time when the terminal receives the unified TCI status activation command, and T HARQ T represents the time between downlink transmission and the corresponding terminal sending an acknowledgment feedback message.

[0239] Alternatively, the meaning of the same parameters in the above formula can be referred to the optional implementation of step S2104.

[0240] Optionally, you may refer to Figure 2g The T shownSSB1 .

[0241] Optionally, TO k1 It can be equal to 0 or 1. For example, given a known TCI state, if the TCI state is not in the active TCI state list of PDSCH, TO k1 It equals 1.

[0242] The method involved in the embodiments of this disclosure may include at least one of steps S2201 to S2204. For example, step S2202 may be implemented as an independent embodiment, steps S2203 to S2204 may be implemented as independent embodiments, and steps S2202 to S2204 may be implemented as independent embodiments, but are not limited thereto.

[0243] In some embodiments, at least one of steps S2201 and S2202 may be optionally omitted or substituted in different embodiments.

[0244] In some embodiments, see Figure 2b Other optional implementation methods described before or after the corresponding instruction manual.

[0245] Figure 2c This is an interactive schematic diagram illustrating a TCI state activation processing method according to an embodiment of this disclosure. Figure 2c As shown, this disclosure relates to a method for processing TCI state activation, the method comprising:

[0246] In step S2301, network device 102 sends configuration information to terminal 101.

[0247] Optionally, alternative implementations of step S2301 can be found in [reference needed]. Figure 2a intermediate step S2101 and Figure 2a Other related parts in the embodiments involved will not be described in detail here.

[0248] In step S2302, network device 102 sends a downlink reference signal to terminal 101.

[0249] In some embodiments, the downlink reference signal includes, but is not limited to, a first RS and / or a second RS.

[0250] Optionally, the first RS is used to activate the first TCI state in the unified TCI state; the second RS is used to activate the second TCI state in the unified TCI state.

[0251] In some embodiments, the first TCI state is a downlink DL TCI state, and the second TCI state is an uplink UL TCI state.

[0252] In one example, for the first TCI state, i.e., the DL TCI state, terminal 101 needs to perform receive beam scanning or time-frequency tracking based on multiple first RSs.

[0253] Optionally, during the first TCI state activation in the mTRP scenario, the first RS can be the RS sent by TRP1 for receiving beam scanning or time-frequency tracking.

[0254] Optionally, the first RS can be an SSB or a CSI-RS.

[0255] In another example, for the second TCI state, i.e. the UL TCI state, terminal 101 needs to perform uplink path loss measurement based on the second RS.

[0256] Optionally, during the second TCI state activation in the mTRP scenario, the second RS can be the RS sent by TRP2 for uplink path loss measurement. Optionally, the second RS can be the path loss reference signal (PL-RS).

[0257] Optionally, the second RS can be an SSB or a CSI-RS.

[0258] Optionally, when PL-RS is not maintained, terminal 101 needs to perform additional path loss calculation for UL transmission. The path loss calculation will depend on the measurement of SSB or CSI-RS, i.e., path loss measurement.

[0259] In some embodiments, in the case of mTRP, the SSB (i.e., the first RS) for T / F tracking or L1-RSRP measurement used for DL ​​TCI state activation in TRP1 may overlap with the SSB / CSI-RS (i.e., the second RS) used for UL path loss calculation in TRP2. Both DL TCI state activation and UL TCI activation require additional delay compared to the original delay time.

[0260] In step S2303, there is a time domain conflict between the first RS and the second RS, and the terminal 101 prioritizes receiving the first RS (e.g., the RS used for beam scanning or time-frequency tracking).

[0261] Optionally, in the first RS, i.e. the first TCI state (DL TCI state) activation, TRP1 transmits RS for receiving beam scanning or time-frequency tracking.

[0262] Optionally, terminal 101 receives the first RS from TRP1, such as receiving the first SSB, for receiving beam scanning or time-frequency tracking, or for L1-RSRP measurement or time-frequency tracking.

[0263] In some embodiments, the time domain conflict between the first RS and the second RS can be addressed by referring to an optional implementation of step S2103.

[0264] In step S2304, terminal 101 determines the delay time for UL TCI state activation based on at least one second cycle.

[0265] In some embodiments, the second period is the period of the second RS, that is, the period of the SSB or CSI-RS used for path loss measurement.

[0266] Optionally, terminal 101 first performs T / F tracking with DL TCI state activation, and the delay time of UL TCI state activation will be extended by one SSB or CSI / RS cycle used for path loss calculation.

[0267] In some embodiments, the UL TCI state activation delay t3 satisfies:

[0268]

[0269] Where n represents the time when the terminal receives the unified TCI status activation command, and T HARQ T represents the time between downlink transmission and the corresponding terminal sending an acknowledgment feedback message. first-target-PL-RS T represents the time elapsed between the terminal receiving the activation command and the first second RS. target-PL-RS Indicates the second cycle. NM is a constant.

[0270] Alternatively, the meaning of the same parameters in the above formula can be found in the optional implementation of steps S2104 or S2204.

[0271] Optionally, if PL-RS is not maintained, NM = 1.

[0272] In some embodiments, if two PL-RSs collide in the time domain, the delay time for UL TCI state activation will require an additional second period, i.e., an additional T period, compared to the above formula. target-PL-RS .

[0273] The method involved in the embodiments of this disclosure may include at least one of steps S2301 to S2304. For example, step S2302 may be implemented as an independent embodiment, steps S2303 to S2304 may be implemented as independent embodiments, and steps S2302 to S2304 may be implemented as independent embodiments, but are not limited thereto.

[0274] In some embodiments, at least one of steps S2301 and S2302 may be optionally omitted or substituted in different embodiments.

[0275] In some embodiments, see Figure 2c Other optional implementation methods described before or after the corresponding instruction manual.

[0276] Figure 2d This is an interactive schematic diagram illustrating a TCI state activation processing method according to an embodiment of this disclosure. Figure 2d As shown, this disclosure relates to a method for processing TCI state activation, the method comprising:

[0277] In step S2401, network device 102 sends configuration information to terminal 101.

[0278] Optionally, alternative implementations of step S2401 can be found in [reference needed]. Figure 2c intermediate step S2301 and Figure 2c Other related parts in the embodiments involved will not be described in detail here.

[0279] In step S2402, network device 102 sends a downlink reference signal to terminal 101.

[0280] Optionally, alternative implementations of step S2402 can be found in [reference needed]. Figure 2c intermediate step S2302 and Figure 2c Other related parts in the embodiments involved will not be described in detail here.

[0281] In step S2403, there is a time domain conflict between the first RS and the second RS, and the terminal 101 prioritizes receiving the second RS (e.g., the RS used for path loss measurement).

[0282] Optionally, in the second RS, i.e. the second TCI state (UL TCI state) activation, TRP2 sends an RS for path loss measurement.

[0283] In some embodiments, the time domain conflict between the first RS and the second RS can be addressed by referring to an optional implementation of step S2103.

[0284] In step S2404, terminal 101 determines the delay time for DL ​​TCI state activation based on the first cycle.

[0285] In some embodiments, the first period is the period of the first RS, i.e., the period of the RS used for time-frequency tracking or L1-RSRP measurement.

[0391] The first RS and the second RS have the same period and the same offset;

[0393] In some embodiments, the first RS or the second RS is one of the following:

[0394] SSB;

[0395] CSI-RS.

[0396] In some embodiments, see Figure 4b Other optional implementation methods described before or after the corresponding instruction manual.

[0397] The method of this disclosure aims to resolve the conflict problem of unified TCI state in the mTRP scenario of TDM, such as the conflict between known and unknown TCI activation, and the conflict between DL TCI activation and UL TCI activation. To facilitate understanding of the embodiments of this disclosure, the following specific examples are provided:

[0398] Example 1:

[0399] For a unified TCI state transition in mTRP, two unified TCI states will be activated. It is possible that one TCI state is known, while the other TCI state is unknown.

[0400] For a known TCI state, if the TCI state is not in the active TCI state list of the PDSCH, the UE requires an additional SSB to obtain the time / frequency of the target TCI state. Typical delay requirements are as follows:

[0401]

[0402] For unknown TCI states, the UE needs to perform additional RX beam scans based on multiple SSBs or CSI-RS. The TCI activation delay is defined as follows:

[0403]

[0404] Where T L1-RSRP It is the time for receiving beam refinement (Rx beam refinement) in FR2.

[0405] Example 2:

[0406] Based on Example 1, when the SSB used for T / F tracking overlaps with the SSB used for L1-RSRP measurement:

[0407] In the mTRP case, assume that the TCI state of TRP1 is unknown, while the TCI state 2 of TRP2 is known. The SSB for T / F tracking in TRP2 may overlap with the SSB / CSI-RS for RX beam scanning in TRP1. Due to the TDM scheme, the UE cannot process the two processes simultaneously and can only receive signals from one direction at a time.

[0408] When SSB and L1-RSRP measurements used for T / F tracking conflict, the following options are available:

[0409] Option 1: The UE receives the first SSB from TRP1 for L1-RSRP;

[0410] Option 2: The UE receives the first SSB from TRP2 for T / F tracking.

[0411] For Option 1:

[0412] The UE will first apply L1-RSRP measurements to TRP1. Assuming an SSB is used for L1-RSRP measurements, the UE will spend 8 SSBs on RX beam scanning. After 8 SSBs, the UE will perform T / F tracking on TRP2. The total delay length will include the L1-RSRP measurement period plus one SSB.

[0413] Optionally, overlap includes both complete overlap and partial overlap. For example... Figure 2e and 2f As shown, in fully overlapping TRPs, the SSB period and offset are the same, while in partially overlapping TRPs, the SSB periods are different.

[0414] Optionally, for both types of overlap, the total delay is:

[0415]

[0416] Among them, T first-SSB2 This is the time interval between the first SSB of TRP 2 (known TCI state) after the L1-RSRP measurement of TRP1 (unknown TCI state). If CSI-RS is used for the L1-RSRP measurement of TRP 1, when the CSI-RS of L1-RSRP overlaps with the SSB for T / F tracking, the total delay requires an additional SSB plus the SSB processing time.

[0417] For Option 2:

[0418] If the UE performs T / F tracking first for TCI activation of TRP2, the UE will require an additional SSB for L1-RSRP measurement of TRP1. The total delay will be extended by one SSB from TRP1 in period TSSB1.

[0419] Combination Figure 2g As shown, the total delay is:

[0420]

[0421] Among them, T SSB1 It is the SSB cycle of the TRP in the unknown TCI state.

[0422] Example 3:

[0423] Based on Example 1, when the SSB used for DL ​​TCI activation overlaps with the CSI-RS / SSB used for UL TCI activation:

[0424] The standard UL TCI activation delay is defined as:

[0425]

[0426] When PL-RS is not maintained, the UE needs to perform additional path loss calculations for UL transmissions. These calculations will depend on the measurements of SSB or CSI-RS. In the mTRP case, the SSB measured by T / F tracking or L1-RSRP for DL ​​TCI activation in TRP1 may overlap with the SSB / CSI-RS for UL path loss calculations in TRP2. Both DL TCI and UL TCI activation require additional delays.

[0427] When a conflict arises between the SSB used for T / F tracking and the SSB / CSI-RS used for UL path loss calculation, the following options are available:

[0428] Option 1: The UE receives the first SSB from TRP2 for UL path loss calculation;

[0429] Option 2: The UE receives the first SSB from TRP1 for T / F tracking or L1-RSRP measurement.

[0430] For Option 1:

[0431] The UE will first perform UL path loss calculation. Therefore, for DL ​​TCI state activation, an SSB is also required. The delay for DL ​​TCI activation is then:

[0432] Given the known situation,

[0433] Regarding unknown situations,

[0434] For Option 2:

[0435] The UE will first perform T / F tracking with DL TCI activation. The UL TCI activation delay will extend the path loss calculation by one SSB or CSI / RS. The UL TCI activation delay is defined as follows:

[0436]

[0437] Alternatively, the two PL-RS may collide with each other, in which case the delay will require an additional RS cycle.

[0438] This disclosure also provides an apparatus for implementing any of the above methods. For example, an apparatus is provided that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Alternatively, another apparatus is provided that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device.

All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
