Embodiments of the present disclosure relate to the field of communications, and more particularly, to a wireless communication method and device.
A Secondary Cell (SCell) is configured by Radio Resource Control (RRC) dedicated signaling. The initial configuration state is a deactivated state, in which data cannot be transmitted and received. The SCell can then be activated through Media Access Control (MAC) Control Element (CE) to transmit and receive data. Activation, deactivation, addition and deletion of a secondary carrier may all result in interruption of transmission of User Equipment (UE) and thus lead to an interruption duration.
Up to now, the interruption duration has been defined only in terms of Synchronization Signal/PBCH Block (SSB), including Automatic Gain Control (AGC) setting based on SSB and timing tracking based on SSB. Considering the long cycle of SSB, it will affect the time when SCell is actually activated, thus resulting in too long interruption duration and affecting system performance.

As shown in
It should be understood that embodiments of the present disclosure are only illustrated by taking the communication system 100 as an example, but are not limited thereto. That is to say, technical solutions of the embodiments of the present disclosure can be applied to various communication systems, such as a Long Term Evolution (LTE) system, an LTE Time Division Duplex (TDD) system, a Universal Mobile Telecommunication System (UMTS) system, a Fifth Generation (5G) communication system (also known as New Radio (NR) communication system), future communication systems, or the like.

Or the network device 120 can be a relay station, access point, vehicle-mounted device, wearable device, hub, switch, bridge, router, network device in a future evolved Public Land Mobile Network (PLMN), or the like.
The terminal device 110 can be any terminal device, including, but not limited to, a terminal device connected wiredly or wirelessly to the network device 120 or another terminal device.
For example, the terminal device 110 may refer to an access terminal, a user device (UE), a user unit, a user station, a mobile station, a mobile platform, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user equipment.

The core network device 130 can be a 5G Core network (5 GC) device, such as an Access and Mobility Management Function (AMF), an Authentication Server Function (AUSF), a User Plane Function (UPF), or a Session Management Function (SMF). Optionally, the core network device 130 can also be an Evolved Packet Core (EPC) device in an LTE network, such as Session Management Function+Core Packet Gateway (SMF+PGW-C) device. It should be understood that SMF+PGW-C can simultaneously implement the functions that SMF and PGW-C can implement. In the course of network evolution, the above core network devices may also be called other names, or new network entities may be formed by partitioning the functions of the core network, for which the embodiments of the present disclosure make no limitation.

SMF can establish a control-plane signaling connection with PCF through NG interface 7 (N7 for short).
It should be understood that devices with communication capabilities in the network/system in the embodiment of the present disclosure can all be referred to as communication devices. Taking the communication system 100 shown in
It should be understood that the terms “system” and “network” in this disclosure are often used interchangeably. The term “and/or” in this disclosure is simply used to described an association relationship between the associated objects, indicating that there can be three relationships. For example, A and/or B can represent three cases: only A exists, both A and B exist, and only B exists. In addition, the character “/” in this disclosure generally indicates that objects before and after the symbol is in a relationship of “OR”.
To facilitate understanding of the solution of the present disclosure, the scheme of carrier aggregation is described below.
Carrier Aggregation (CA) allows, by jointly scheduling and using resources on multiple Component Carriers (CCs), an NR system to support a greater bandwidth, thereby enabling a higher peak system rate. Based on the continuity of the aggregated carriers on the spectrum, CA can be divided into continuous carrier aggregation and discontinuous carrier aggregation. According to whether the bands on which the aggregated carriers are located are the same, it can be divided into intra-band carrier aggregation and inter-band carrier aggregation.
In NR CA, there is one and only one Primary Cell Component (PCC). PCC provides RRC signaling connection, Non-Access Stratum (NAS) function, security, etc. Physical Uplink Control Channel (PUCCH) exists on PCC and only on PCC. SCell Component (SCC) only provides additional wireless resources. PCC and SCC are both called service areas. It is also specified in the standard that up to five aggregated carriers can be supported, that is, the maximum bandwidth after aggregation is 100 MHZ, and the aggregated carriers belong to the same base station. All aggregated carriers use the same Cell Radio Network Temporary Identity (C-RNTI), and the implementation of base stations ensures that C-RNTI does not conflict in the cell where each carrier is located. Since both asymmetric carrier aggregation and symmetric carrier aggregation are supported, it is required that the aggregated carriers must have downlink and may have no uplink. Moreover, there must be Physical Downlink Control Channel (PDCCH) and PUCCH for the primary carrier cell, and only the primary carrier cell has PUCCH, and other secondary carrier cells may have PDCCH.
SCell is configured with RRC-specific signaling, and the initial configuration state is a deactivated state, in which data cannot be transmitted or received. Then the SCell can be activated via MAC CE, to transmit and receive data. This architecture is not optimal in terms of delay of SCell configuration and activation. And this delay reduces the efficiency of CA usage and wireless resources, especially in a small cell deployment scenario. In a dense small cell deployment scenario, each Scell has a high signaling load, especially when each Scell needs to be configured separately. Thus the current CA architecture introduces an additional delay, which limits the use of CA and reduces the benefits of CA load sharing.
Activation, deactivation, addition and deletion of a secondary carrier may cause interruption in the transmission of the terminal device. It should be noted that the activation, deactivation, addition and deletion of a secondary carrier can also be understood as the activation, deactivation, addition and deletion of a Scell. For the convenience of description, the activation, deactivation, addition and deletion of a SCell are collectively referred to as processing procedures for the SCell.
Below is described how to activate BWP.
In R16, dormant BWP is introduced to solve the terminal's power consumption problem. That is, when BWP is configured to be dormant, the terminal does not need to detect PDCCH, which saves the terminal's power consumption. Dormant BWP is configured in three manners: DCI format 2_6, DCI format 0_1/1_1 plus dormant BWP indicator field, and redesigned DCI format 1_1. Specifically, indication can be made as follows.
A “0” value of a bit of a bitmap indicates: an active DL BWP, provided by dormant BWP-Id, for the UE for a corresponding activated SCell.
A “1” value of a bit of the bitmap indicates: an active DL BWP, provided by firstWithinActiveTimeBWP-Id, for the UE for a corresponding active SCell, if a DL BWP is the dormant DL BWP; or a current active DL BWP, for the UE for a corresponding activated SCell, if the current DL BWP is not the dormant DL BWP.
Based on this, the UE sets the active DL BWP to the indicated active DL BWP.
As shown in
In the processing procedure for an SCell, time periods B, C, D, E, F and G (that is, T) can handle the delay in the processing procedure, and among them D, E, F can be used as an execution window of the processing procedure. During executing the processing procedure by the terminal device, there may arise an interruption, that is, an interruption duration, such as the interruption between C and D shown in
Each time period in
Here, a known cell can be interpreted as a cell that has been searched by a terminal device, and an unknown cell can be interpreted as a cell that has not been searched by a terminal device. Based on this, as shown in Table 1, in the processing procedure for a known cell, the duration of E can be 0; and for a known cell with a SCell measurement period less than or equal to 160 ms, the duration of D can also be 0. However, for a known cell with a SCell measurement period greater than 160 ms, the duration of D is 1*TFirstSSB_MAX, that is, the operation within period D needs to be re-executed. Similarly, for an unknown cell, corresponding operations need to be performed within each time period, for example, cell search only for an unknown cell, that is, for an unknown cell, the duration E is not zero. Here, Trs can represent the time spent in cell search.
As shown in
For details of interruption, reference can be made to relevant parts of the 3rd Generation Partnership Project (3GPP) protocol TS 38.133.
Taking the processing procedure as an example of activation or deactivation, when activating or deactivating the SCell, the terminal device is allowed to make an interruption on any active serving cell.
The interruption duration for activation/deactivation of an SCell can be up to the duration shown in table 8.2.4.2-1. If the active serving cell is not in the same band as any of the SCells being activated or deactivated, the requirements for Sync apply for synchronous NR-DC, and for asynchronous NR-DC if the active serving cell is in the same CG as all the SCells being activated; and the requirements for Async apply for asynchronous NR-DC if the active serving cell is not in the same CG as any of the SCells being activated.
Or the interruption duration of the activation/deactivation of the SCell can be up to the duration shown in table 8.2.4.2.2. If the active serving cells are not in the same band as any of the SCells being activated or deactivated, the cell specific reference signals from the active serving cells and the SCells being activated or deactivated are available in the same slot.
Here, table 8.2.4.2.2-1 shows the interruption duration for SCell activation/deactivation for inter-band DC/CA, where μ represents the subcarrier interval. Based on table 8.2.4.2.2-1, it can be seen that the interruption duration is related to the subcarrier interval, the NR slot length of the victim cell, and sync/async.
Here, table 8.2.4.2.2-2 shows the interruption duration for SCell activation/deactivation for intra-band DC/CA, where μ represents the subcarrier interval. Based on table 8.2.4.2.2-2, it can be seen that interruption duration is related to subcarrier interval, NR timeslot length, TSMTC_duration and Nslotsubframe,μ.
Based on 8.2.4.2.1 and 8.2.4.2.2, it can be known that the activation or deactivation of subcarrier for intra-band and inter-band DC or CA brings different interruptions, that is, generating different interruption durations. Because the interruption duration is defined based on SSB, including AGC setting based on SSB and timing tracking based on SSB. Considering the long cycle of SSB, this will affect the actual activation time of SCell, and thus will lead to excessive interruption duration and affect the system performance.
Embodiments of the present disclosure provide a wireless communication method and device, which can flexibly control the delay and interruption duration in the processing procedure and improve the system performance.
As shown in
At S210, first indication information is obtained. The first indication information is used to indicate a first reference signal used in a processing procedure for an SCell, the processing procedure including at least one of activation, deactivation, addition or deletion.
At S220, the processing procedure is executed based on the first indication information.
Based on the above technical solution, the first reference signal is indicated by the first indication information, and then the first reference signal is used to perform the processing procedure, which allows flexible configuration of the reference signal, and enables the terminal device to make faster AGC adjustment to reduce the impact of interruption on other cells, thus enabling flexible control of delay and interruption duration in the processing procedure, reducing the terminal complexity, and saving system resources and the like.
In some embodiments of the present disclosure, the first indication information is used to instruct a terminal device to trigger the processing procedure for the SCell and is used to indicate the first reference signal used in the processing procedure.
In some embodiments of the present disclosure, the first indication information is carried in at least one of: Media Access Control Control Element (MAC CE), Downlink Control Information (DCI) or second indication information used to instruct a terminal device to switch Bandwidth Part (BWP).
In the embodiment of the present disclosure, the flexible and fast trigger scheme allows fast processing for the SCell, so as to reduce the delay and improve the system performance.
In some embodiments of the present disclosure, the second indication information is carried in at least one of: Downlink Control Information (DCI), timer configuration information, or Radio Resource Control (RRC) signaling.
In other words, the first indication information can be carried in any of the following ways. Mode 1: MAC-CE configuration triggers the activation of the SCell, and indicates configuration information 1 of the reference signal related to the physical layer. Mode 2: DCI configuration triggers the activation of the SCell, and at the same time DCI indicates configuration information 2 of the reference signal TRS. Mode 3: the activation of the SCell is triggered with and based on BWP switching, and BWP switching can include three ways of trigger, namely, DCI/timer/RRC trigger. The BWP configuration indicates the reference signal configuration information 3 required for the activation of the SCell. The above configuration information 1/2/3 at least includes: the cycle, length and other information of the reference signal.
In some embodiments of the present disclosure, the first reference signal is used in at least one of: adjusting Automatic Gain Control (AGC), cell search or time-frequency synchronization.
In some embodiments of the present disclosure, the first reference signal includes a pilot signal. Optionally, the pilot signal includes at least one of: Synchronous Signal/physical broadcast channel Block (SSB), Channel State Information Reference Signal (CSI-RS) or Tracking Reference Signal (TRS). Of course, the pilot signal can also include other pilot signals, which are not specifically limited in the embodiment of the present disclosure.
In the embodiment of present disclosure, the processing procedure can be executed based on different reference signals, and as a result, different delays and interruption durations will be incurred during the terminal device executing the processing procedure. Then, it is required to redefine the introduced delay and interruption duration based on the type of reference signal, and it is even required to redefine the capability information of terminal device, so that different radio resource management (RRM) requirements are supported through terminal devices with different capabilities.
In some embodiments of the present disclosure, the S220 may include: executing, in an execution window, the processing procedure based on the first indication information.
The first reference signal includes at least one reference signal, and the execution window includes a reference signal cycle of the at least one reference signal, or the execution window includes a measurement cycle of the at least one reference signal, or the execution window is determined based on implementation of a terminal device.
It should be understood that the execution window involved in the embodiment of the present disclosure can be at least one of D, E and F as shown in
In addition, it should be noted that in the embodiment of the present disclosure, the reference signal cycle of the at least one reference signal can be understood as the cycle of the at least one reference signal itself. For example, for SSB, the reference signal cycle can be understood as the SSB cycle. The measurement cycle of the at least one reference signal can be understood as the measurement cycle for measuring the at least one reference signal. For example, the measurement cycle for SSB can be understood as the cycle of SMTC measurement window. The SMTC measurement window can also be called the duration of the SMTC. The terminal device needs to measure the reference signal based on the measurement cycle to avoid unnecessary measurement and reduce the power consumption of the terminal device. Taking SSB as an example, SSB can be measured based on the cycle of SMTC measurement window. The terminal device detects and measures the SSB according to the SMTC measurement window, and then reports a measurement result to the network device or makes a decision on cell selection and reselection according to the measurement result.
In addition, the execution window including the reference signal cycle of the at least one reference signal, or the execution window including the measurement cycle of the at least one reference signal, is intended to illustrate that the execution window can include resources for a certain number of reference signals or resources for measuring a certain number of reference signals. Taking the execution window including the SSB cycle of the SSB as an example, it can be understood as the execution window including SSB transmission resources for the SSB or SMTC measurement window resources used to measure the SSB. Moreover, the embodiment of the present disclosure does not limit the specific number of cycles included in the execution window.
In some embodiments of the present disclosure, the at least one reference signal is Synchronous Signal/physical broadcast channel Block (SSB), and the execution window includes X SSB cycles or X SSB measurement cycles, where X is a positive integer; or the at least one reference signal is tracking reference signal (TRS), and the execution window includes Y TRS cycles or Y TRS measurement cycles, where Y is a positive integer; or the first reference signal is TRS and SSB, and the execution window includes Z1 SSB cycles and Z2 TRS cycles, or the execution window includes Z1 SSB measurement cycles and Z2 TRS measurement cycles, where Z1 and Z2 are positive integers; or the first reference signal is TRS or SSB, and the execution window includes a longest one of Z1 SSB cycles and Z2 TRS cycles, or the execution window includes a longest one of Z1 SSB measurement cycles and Z2 TRS measurement cycles; or the first reference signal is a default reference signal, and the execution window is determined based on implementation of the terminal device.
Taking the reference signal cycle of the execution window including at least one reference signal as an example, at S220 the processing procedure can be executed in any one of the following ways. Mode 1: the terminal device executes the processing procedure, according to the reference signal in the configuration information indicated after triggering. If the reference signal is configured as SSB, the processing procedure needs to be completed within X SSB cycles. Mode 2: the terminal device executes the processing procedure, according to the reference signal in the configuration information indicated after triggering. If the reference signal is configured as TRS, the processing procedure needs to be completed after Y TRS cycles. Mode 3: the terminal device executes the processing procedure, according to the reference signal in the configuration information indicated after triggering. If the reference signal is configured as TRS and SSB, the processing procedure needs to be completed after Z1 SSB cycles and Z2 TRS cycles. Mode 4: the terminal device executes the processing procedure, according to the reference signal in the configuration information indicated after triggering. If the reference signal is configured as TRS or SSB, the processing procedure needs to be completed within no longer than the maximum of Z1 SSB cycles or Z2 TRS cycles. Mode 5: the terminal device executes the processing procedure, according to the reference signal in the configuration information indicated after triggering. If the reference signal is configured as default, then UE completes the processing procedure based on its implementation, the required time window being compliant with the existing protocol. The configuration information indicated after triggering (that is, the first indication information) can be explicit or implicit.
In some embodiments of the present disclosure, the first indication information is further used to indicate a number of reference signal cycles or measurement cycles of each of the at least one reference signal.
In some embodiments of the present disclosure, the execution window includes at least one longest cycle. The longest cycle is a longest cycle of all reference signals the same as the first reference signal which are configured for serving cells of the terminal device, or the longest cycle is a longest cycle of all reference signals the same as the first reference signal which are configured for a group of cells to be activated of the terminal device.
For example, the length of the execution window includes at least one of: X, Y, Z1 or Z2 reference signal cycles or measurement cycles. The reference signal cycle or measurement cycle is taken as the longest cycle in all service cells configured with the first reference signal. For example, the length of the execution window includes at least one of: X, Y, Z1 or Z2 reference signal cycles or measurement cycles. The reference signal cycle or measurement cycle is the longest cycle in the current group of cells to be activated.
In some embodiments of the present disclosure, the SCell is a cell within a frequency range FR2, and a length of the execution window is N times the number of reference signal cycles or measurement cycles of the at least one reference signal, where N represents a beam scanning scaling factor.
It should be noted that the embodiment of the present disclosure does not specifically limit the number of reference signal cycles of the at least one reference signal, the number of measurement cycles of the at least one reference signal, and the value of N. As an example, the number of reference signal cycles of the at least one reference signal can be 2, 4 or 8, and the like, and the value of N can be 8, and the like.
As the processing procedure is executed by at least one reference signal, the determination method of interruption duration also needs to be updated. The following describes how to determine the interruption duration.
In some embodiments of the present disclosure, the method 200 may also include: determining an interruption duration of the processing procedure based on a measurement window of a reference signal required by the processing procedure, for intra-band Dual Connectivity or Carrier Aggregation (DC/CA).
In other words, for intra-band Dual Connectivity or Carrier Aggregation (DC/CA), the duration in the processing procedure is related to the measurement window of the reference signal required by the processing procedure (that is, the measurement window of the first reference signal).
In some embodiments of the present disclosure, the method 200 may also include: determining an interruption duration of the processing procedure based on a measurement window of a reference signal required by the processing procedure, for inter-band Dual Connectivity or Carrier Aggregation (DC/CA).
In other words, for inter-band Dual Connectivity or Carrier Aggregation (DC/CA), the duration in the processing procedure is related to the measurement window of the reference signal required by the processing procedure (that is, the measurement window of the first reference signal).
Optionally, the interruption duration is determined based on a duration of an SSB Measurement Timing Configuration (SMTC), TSMTC_duration, when the first reference signal is SSB; and/or the interruption duration is determined based on a duration of a measurement window of a TRS, TTRS measurement windows_duration, when the first reference signal is TRS.
In other words, the measurement window of SSB can be the duration of SMTC, TSMTC_duration; and the measurement window of TRS can be the duration of the TRS measurement window, TTRS measurement windows_duration. Of course, in other embodiments of the present disclosure, similar to SMTC, TRS can have TRS measurement timing configuration for TRS measurement. In this case, the duration of TRS measurement window TTRS measurement windows_duration can also be called the duration of TRS measurement timing configuration.
For example, taking the first reference signal being SSB as an example, the interruption duration can be determined based on the following Table 2.
Here, table 2 shows the interruption duration for SCell activation/deactivation for intra-band DC/CA, where μ represents the subcarrier interval. As shown in table 2, the interruption duration is determined based on TSMTC_duration.
Optionally, the interruption duration is determined, based on a maximum one of the measurement window of SSB and the measurement window of TRS.
Optionally, the interruption duration is determined based on the measurement window of a predetermined length, when the first reference signal is TRS and no measurement window is defined for TRS.
In some embodiments of the present disclosure, the method 200 may also include: determining an interruption duration of the processing procedure based on a duration of an SSB Measurement Timing Configuration (SMTC), TSMTC_duration for intra-band Dual Connectivity or Carrier Aggregation (DC/CA).
In other words, the duration in the processing procedure is not related to the type of reference signal required by the processing procedure. That is, no matter what kind of reference signal, the interruption duration of the processing procedure can be determined based on the duration of the SMTC, TSMTC_duration.
For example, the duration in the processing procedure is not related to the type of reference signal required by the processing procedure. That is, no matter what kind of reference signal, the interruption duration can be determined based on the above table 2.
Optionally, the duration of the SMTC TSMTC_duration is: a longest one of SMTC durations in all active serving cells and an SCell being activated, when the SCell is activated; or a longest one of SMTC durations in all active serving cells in a same frequency band, when the SCell is deactivated.
In some embodiments of the present disclosure, the method 200 may also include: determining, for inter-band Dual Connectivity or Carrier Aggregation (DC/CA), an interruption duration of the processing procedure based on synchrony or asynchrony of the inter-band DC/CA.
In other words, the duration in the processing procedure is not related to the type of reference signal required by the processing procedure. That is, no matter what kind of reference signal, the interruption duration of the processing procedure can be determined based on the synchronous or asynchronous of the inter-band DC/CA.
For example, the interruption duration can be determined based on the following Table 3:
Here, table 3 shows the interruption duration for SCell activation/deactivation for inter-band DC/CA, where μ represents the subcarrier interval. As shown in table 3, the interruption duration is related to the subcarrier interval, the NR timeslot length of the victim cell, and sync/async.
It should be noted that for intra-band Dual Connectivity or Carrier Aggregation (DC/CA) and for inter-band Dual Connectivity or Carrier Aggregation (DC/CA), the determination method of interruption duration can be the same or different, for which the embodiment of the present disclosure does not make specific limitations. For example, for intra-band Dual Connectivity or Carrier Aggregation (DC/CA), the interruption duration of the processing procedure can be determined based on the measurement window of the reference signal required by the processing procedure. For inter-band Dual Connectivity or Carrier Aggregation (DC/CA), other methods can be used to determine the interruption duration in the processing procedure.
For example, as a specific example, the interruption duration can be determined in any one of the following ways.
Mode 1: The determination method of interruption duration for inter-band DC/CA remains unchanged, that is, the interruption duration is determined according to table 8.2.4.2.2-1. The interruption duration for intra-band DC/CA is determined based on the measurement window of the first reference signal. For example, the interruption duration is determined based on the duration of the SMTC TSMTC_duration, when the first reference signal is SSB; and/or, the interruption duration is determined based on the duration of the measurement window of the TRS TTRS measurement windows_duration, when the first reference signal is TRS. Both SSB and TRS have measurement timing configuration (i.e. measurement window), and the largest of the measurement windows corresponding to SSB and TRS is taken as a unit. If no measurement window is defined for the TRS in the above case, a 5 ms measurement window is taken.
Mode 2: The interruption duration for inter-band DC/CA remains unchanged, that is, the interruption duration is determined according to table 8.2.4.2.2-1. The interruption requirements of intra-band DC/CA are still determined in accordance with TSMTC_duration, that is, the interruption duration is determined according to table 8.2.4.2.2-2.
In some embodiments of the present disclosure, the method 200 may further include: transmitting capability information used to indicate a capability used for a terminal device to support the processing procedure.
Optionally, the capability information is used to indicate the terminal device only supports a capability of fast processing based on tracking reference signal (TRS), or the capability information is used to indicate the terminal device supports a capability of fast processing based on TRS and Synchronous Signal/physical broadcast channel Block (SSB), or the capability information is used to indicate the terminal device supports a capability of fast processing and the interruption duration is determined based on a TRS cycle, or the capability information is used to indicate the terminal device supports a capability of fast processing and the interruption duration is determined based on implementation of the terminal device.
By introducing the capability information of different terminal devices to support different radio resource management (RRM) requirements, flexibility of network scheduling can be ensured.
In other words, the capability information of the terminal device can be defined in any one of the following ways.
Mode 1: terminal device capability 1 is introduced that only supports TRS-based fast SCell activation. Only if the terminal device reports that it supports this capability, the network will allow the terminal device to be configured with fast activation, and implement it according to the requirements of fast activation. Here, the processing duration and interruption duration are both determined by the TRS cycle.
Mode 2: the terminal device capability 2 is introduced that supports fast SCell activation based on a hybrid of TRS and SSB. Only if the terminal device reports that it supports this capability, the network will allow the terminal device to be configured with fast activation, and implement it according to the requirements of fast activation. The processing duration and interruption duration are determined jointly by SSB and TRS.
Mode 3: terminal device capability 3 is introduced that supports fast SCell activation, without specifying what reference signal to use. Only if the terminal device reports that it supports this capability, the network will allow the terminal device to be configured with fast activation, and implement it according to the requirements of fast activation. The processing duration and interruption duration are both determined by the TRS cycle.
Mode 4: terminal device capability 4 is introduced that supports fast SCell activation, without specifying what reference signal to use. Only if the terminal device reports that it supports this capability, the network will allow the terminal device to be configured with fast activation, and implement it according to the requirements of fast activation. The processing duration and interruption duration only need to meet the existing requirements, but are based on the implementation of terminal device.
It should be noted that the terminal device which does not support the terminal device capacity 1/2/3/4 only needs to meet the existing requirements, and the network does not expect to schedule the terminal device earlier. For terminal device supporting capacity 1/2/3/4, the network will expect to fast-activate the corresponding SCell earlier and schedule the terminal device in the SCell.
In some embodiments of the present disclosure, the first indication information is further used to indicate capability information, and the capability information is used to indicate a capability needed to be supported by the terminal device when the terminal device uses the first reference signal in the processing procedure.
In other words, while indicating the first reference signal, the first indication information can further indicate the capability that the terminal device needs to support when the processing procedure is performed using the first reference signal.
Optionally, the first indication information indicates the capability information via the first reference signal.
Optionally, the capability information is used to indicate the capability needed to be supported by the terminal device when the terminal device uses Tracking Reference Signal (TRS) in the processing procedure, or the capability information is used to indicate the capability needed to be supported by the terminal device when the terminal device uses TRS and Synchronization Signal/physical broadcast channel Block (SSB) in the processing procedure, or the capability information is used to indicate the terminal device needs to support a capability of fast processing and the interruption duration is determined based on a TRS cycle, or the capability information is used to indicate the terminal device needs to support a capability of fast processing and the interruption duration is determined based on implementation of the terminal device.
