The technical solution provided by the embodiments of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

As shown in Figure 2, it is a flow chart of a communication method 200 provided in an embodiment of the present application, and the method 200 can be, but is not limited to, executed by a terminal, and specifically can be executed by hardware or software installed in the terminal. In this embodiment, the method 200 includes at least the following steps.

S210. The terminal determines a target reference signal according to the first information.

The terminal may be, but is not limited to, a non-reduced capability (RedCap) terminal, referred to as Non-RedCap UE, etc. Of course, the Non-RedCap UE is relative to the RedCap UE terminal, wherein the RedCap UE is a terminal that needs to reduce complexity in terms of the number of receiving antennas, transmitting antennas, supported bandwidth, time and capability of terminal processing data and signals, etc., such as its RF BW and BB BW support a maximum of 20MHz in FR1, etc.

Based on this, in this embodiment, when the terminal performs a predetermined communication process based on the measurement of the target reference signal, the target reference signal is determined through the first information, so as to ensure that the terminal and the network side device have a consistent understanding of the target reference signal, such as the type of the target reference signal, whether the target reference signal is configured in the active BWP or outside the active BWP, etc., thereby ensuring the system performance of the communication system.

That is to say, the first information described in this embodiment is used to configure or indicate the determination method of the target reference signal to ensure that the terminal and the network side device have consistent understanding of the target reference signal. Optionally, the first information can be implemented by protocol agreement, network side configuration, high-level configuration, default, etc., which is not limited here.

In addition, in this embodiment, the target reference signal may include at least one of a first reference signal and a second reference signal, the first reference signal is a cell definition (Cell Defining, CD) reference signal, and the second reference signal is a non-cell definition (Non Cell Defining, NCD) reference signal.

For the non-cell defined reference signal, the corresponding reference signal configuration may be a cell-level configuration or a BWP-level configuration. For example, if it is a cell-level configuration, the terminal may determine whether the second reference signal is configured in the active BWP or outside the active BWP according to the frequency domain position of the second reference signal. For another example, if it is a BWP-level configuration, the terminal may determine that the frequency domain position of the second reference signal can only be configured in the active BWP.

It is worth noting that, in the present embodiment, the target reference signal may be but is not limited to SSB, etc. Correspondingly, the first reference signal may be but is not limited to CD-SSB, and the second reference signal may be but is not limited to NCD-SSB.

S220: Execute a predetermined communication process based on the measurement of the target reference signal.

The predetermined communication process may include but is not limited to at least one of radio link monitoring, beam management, beam failure recovery, and radio resource management measurement (Radio resource management, RRM). The RRM may include but is not limited to intra-frequency measurement, inter-frequency measurement, serving cell measurement, neighboring cell measurement, At least one of (Neighbor cell measurement).

In this embodiment, the terminal determines the target reference signal through the first information, and then performs a predetermined communication process based on the measurement of the target reference signal, thereby ensuring that the network side device and the terminal have a consistent understanding of the target reference signal, thereby ensuring the performance of the communication system.

As shown in Figure 3, it is a flow chart of a communication method 300 provided in an embodiment of the present application, and the method 300 can be, but is not limited to, executed by a terminal, and specifically can be executed by hardware or software installed in the terminal. In this embodiment, the method 300 includes at least the following steps.

S310. The terminal determines a target reference signal according to first information.

The first information is used to configure or indicate a method for determining the target reference signal, the target reference signal includes at least one of a first reference signal and a second reference signal, the first reference signal is a cell-defined reference signal, and the second reference signal is a non-cell-defined reference signal.

It can be understood that, in addition to referring to the relevant description in method embodiment 200, the implementation process of S310 may include, as a possible implementation method, at least one of the following (11)-(14).

(11) Network configuration or indication information. For example, the network configuration or indication information may be that the target reference signal is the first reference signal or the second reference signal, or the network configuration or indication information may be how the target reference signal is configured, such as determining the target reference signal according to implementation information of the terminal or a predetermined rule.

(12) Information agreed upon or defaulted by protocol. For example, if the network does not configure or instruct, it may be agreed upon or defaulted by protocol that the target reference signal is the first reference signal or the second reference signal, or it may be agreed upon or defaulted by protocol that the configuration method of the target reference signal is, such as determining the target reference signal according to the implementation information of the terminal or a predetermined rule; or it may be agreed upon by protocol that the terminal always uses the first reference signal or the second reference signal to perform a predetermined communication process.

(13)Terminal implementation information.

For example, whether the terminal uses the first reference signal or the second reference signal as the target reference signal depends on the implementation of the terminal, that is, the terminal implementation information. In this embodiment, the implementation information of the terminal may be how to reduce the RF BW of the terminal to help the terminal save power, or the terminal can complete all measurements in the predetermined communication process based on the target reference signal, or the terminal can complete the measurement without opening a larger RF BW to achieve the purpose of power saving, etc.

(14) A predetermined rule, wherein the predetermined rule includes a rule for determining the target reference signal.

The predetermined rule may be determined by protocol agreement, high-level configuration or network-side configuration.

In one implementation, the predetermined rule may include at least one of the following (a)-(f).

(a) A reference signal whose center frequency is closest to the center frequency of the activated downlink bandwidth part active BWP is determined as the target reference signal.

(b) The reference signal whose frequency domain position is closest to the frequency domain position where the active BWP is located is determined as the target reference signal. The frequency domain position can be the frequency domain starting position, the frequency domain ending position, etc., which is not limited here.

(c) Determine the reference signal located in the active BWP as the target reference signal.

(d) Determine the reference signal with the smallest period as the target reference signal. For example, if the period of the first reference signal is smaller than the period of the second reference signal, the first reference signal may be determined to be the target reference signal.

(e) Determine the reference signal with the largest period as the target reference signal. For example, if the period of the first reference signal is greater than the period of the second reference signal, the first reference signal may be determined to be the target reference signal.

(f) Determine the reference signal with the largest transmission power as the target reference signal. For example, if the transmission power of the first reference signal is greater than the transmission power of the second reference signal, the first reference signal may be determined as the target reference signal.

In this case, as a possible implementation method, the terminal can also determine the target reference signal according to the first information when at least one of the following situations 1-3 is met, thereby maintaining the flexibility of the network side device in configuring the BWP and the reference signal, that is, there is no restriction on the configuration of the network side, allowing situations 1-3 to occur. At the same time, when the following situations 1-3 occur, the terminal and the network side device can also have a consistent understanding of the reference signal used, that is, the network side device knows which reference signal the terminal will use for measurement, which can help the network scheduling decision, for example, the network side device can avoid scheduling other transmissions other than the reference signal for the terminal, thereby avoiding time domain or frequency domain conflicts between other transmissions and the reference signal used by the terminal.

Scenario 1: As shown in FIG. 4a , the terminal supports the first capability or the second capability, and no reference signal (such as SSB) exists in the active BWP of the terminal, but the first reference signal and the second reference signal exist outside the active BWP of the terminal and in the bandwidth of the corresponding carrier to be measured.

The first capability is that there is no reference signal in the active BWP of the terminal, and the terminal supports the execution of a predetermined communication process based on the measurement of the target reference signal without interruption outside the active BWP; the second capability is that there is no reference signal in the active BWP of the terminal, and the terminal supports the execution of a predetermined communication process based on the measurement of the target reference signal outside the active BWP and with interruption in the bandwidth of the corresponding carrier to be measured.

Exemplarily, assuming that situation 1 is met, when the terminal determines the target reference signal according to its own implementation information, if the terminal implementation information is to reduce the RF BW of the terminal and help the terminal save power, then the terminal can determine the reference signal with the smallest difference between the center frequency and the center frequency of the active DL BWP (f-bwp) as the target reference signal for measurement.

It should be noted that the first capability and the second capability mentioned in the context of this application may also include at least one of the following (a)-(c).

(a) The terminal does not expect to receive downlink signals or channels outside the active BWP. The downlink signals or channels may be, but are not limited to, physical downlink shared channel (PDSCH), physical downlink control channel (PDCCH), channel state information reference signal (CSI-RS), etc.

(b) The terminal does not expect to send uplink signals or channels outside the active BWP. The uplink signals or channels may be, but are not limited to, physical uplink shared channels (Physical Uplink Shared Channel, PUSCH), physical uplink control channels (Physical Uplink Control Channel, PUCCH), physical random access channels (Physical Random Access Channel, PRACH), sounding reference signals (Sounding Reference Signal, SRS) send.

(c) If Control Resource Set 0 (CORESET#0) is configured on the corresponding carrier to be measured, the bandwidth of CORESET#0 may not be included in the active BWP of the terminal.

In addition, in situation 1, the terminal may include not only non-RedCap UE but also RedCap UE, which is not limited here.

Scenario 2: As shown in FIG4b, the terminal supports a third capability, and the first reference signal and the second reference signal exist in the active BWP of the terminal. The third capability is that the second reference signal (such as a non-cell defined reference signal) exists in the active BWP of the terminal, and the terminal supports performing the predetermined communication process based on the measurement of the second reference signal in the active BWP.

Exemplarily, assuming that when situation 2 is met, the terminal determines the target reference signal based on its own implementation information. Then, if the terminal implementation information is to complete all measurements in a predetermined communication process (such as RRM, RLM, BM, BFR, etc.) based on the target communication process, then the terminal can determine the reference signal defined by the cell as the target reference signal for relevant measurements.

It should be noted that, in the present application, in the third capability mentioned in the context of the present application, it may also include that if CORESET#0 is configured on the corresponding carrier to be measured, then the bandwidth of CORESET#0 may not be included in the active BWP of the terminal.

In addition, in situation 2, the terminal may include non-RedCap UE but not RedCap UE, and no limitation is made here.

Scenario 3: As shown in Figures 4c and 4d, the terminal supports the first capability and the third capability, and the first reference signal or the second reference signal exists in the active BWP of the terminal, and the second reference signal or the first reference signal exists outside the active BWP of the terminal and in the bandwidth of the corresponding carrier to be measured. The first capability is that there is no reference signal in the active BWP of the terminal, and the terminal supports the execution of a predetermined communication process based on the measurement of the target reference signal without interruption outside the active BWP; the third capability is that the second reference signal (such as a non-cell defined reference signal) exists in the active BWP of the terminal, and the terminal supports the execution of the predetermined communication process based on the measurement of the second reference signal in the active BWP.

Exemplarily, assuming that situation 3 is met, when the terminal determines the target reference signal based on its own implementation information, if the terminal implementation information is that the measurement can be completed without opening a larger RF BW to reduce terminal power consumption, then the terminal can determine the reference signal located in the active BWP as the target reference signal for measurement.

It should be noted that in scenario 3, the terminal may include not only non-RedCap UE but also RedCap UE, and there is no limitation here.

S320: Execute a predetermined communication process based on the measurement of the target reference signal.

It can be understood that the implementation process of S320 can refer to the relevant description in the aforementioned method embodiment 200, and achieve the same or corresponding technical effect. To avoid repetition, it will not be repeated here.

In this embodiment, by providing a plurality of different target reference signal determination methods, the flexibility and reliability of target reference signal determination are ensured.

As shown in Figure 5, it is a flow chart of a communication method 500 provided in an embodiment of the present application, and the method 500 can be, but is not limited to, executed by a terminal, and specifically can be executed by hardware or software installed in the terminal. In this embodiment, the method 500 includes at least the following steps.

S510: The terminal receives first indication information.

The first indication information is used to enable a target capability, and the target capability includes at least one of the first capability, the second capability, and the third capability. Optionally, the first indication information may be, but is not limited to, Radio Resource Control (RRC) signaling, such as UE-specific RRC signaling, or RRC signaling configured for each cell (per cell) or each BWP (per BWP), which is not limited here.

That is to say, when measuring the target reference signal, the network side device can enable the capabilities supported by the terminal through the first indication information to ensure the consistency of the understanding of the capabilities supported by the terminal between the network side device and the terminal, thereby enabling the network side to perform correct scheduling.

In this case, if the network side device enables two or more target capabilities, then the terminal can determine one from at least two of the enabled first capability, second capability, and third capability as the target capability used in the predetermined communication process based on the reference signal configuration information.

For example, when the second reference signal exists in the active BWP, the terminal can determine that the third capability is the target capability used in the predetermined communication process from at least two of the enabled first capability, second capability, and third capability.

For another example, when the first reference signal and the second reference signal do not exist in the active BWP, or when the first reference signal and the second reference signal exist in the active BWP, the terminal may determine that the first capability or the second capability is the target capability used in the predetermined communication process from at least two of the enabled first capability, second capability, and third capability.

In addition, when the second reference signal does not exist in the active BWP but the first reference signal exists, the terminal behavior of the terminal is consistent with the terminal behavior in the related technology R15, such as using the reference signal in the active BWP as the target reference signal, and not using any of the first capability, the second capability, and the third capability when performing reference signal measurement.

It is worth noting that in order to ensure that the reference signal, active BWP and other configurations configured by the network side device for the terminal match the capabilities supported by the terminal to improve the reliability of the reference signal measurement results, in this embodiment, the terminal can report its own unrestricted BWP operation capabilities to the network side device, such as at least one of the first capability, the second capability, and the third capability. Among them, the first capability is that the terminal supports the execution of a predetermined communication process based on the measurement of the reference signal without interruption outside the active bandwidth part active BWP. The second capability is that no reference signal is configured in the active BWP of the terminal, but the terminal supports the execution of a predetermined communication process based on the measurement of the reference signal outside the active BWP but in the bandwidth of the corresponding carrier to be measured. The third capability is that the terminal supports the execution of the predetermined communication process based on the measurement of the second reference signal in the active BWP.

Of course, when the terminal reports the capability of unrestricted BWP operation, the following conditions must be met: On the one hand, it can ensure the terminal's unlimited flexibility in implementing BWP operations and ensure that network-side devices perform relevant configuration and scheduling of measurements within the terminal's capabilities. On the other hand, limiting the terminal's capability reporting can simplify the configuration of network-side devices, simplify protocol specifications, and simplify related processes.

Case 1: If the reported capability that has no restriction on BWP operation includes the first capability, then the terminal does not report that it supports the second capability or reports that it does not support the second capability.

Case 2: If the reported capability that has no restriction on BWP operation includes the first capability, then the terminal reports or does not report support for the third capability.

Scenario 3: If the reported capabilities that are not restricted for BWP operation include the second capability, then the terminal reports that it supports the third capability and the fourth capability, but does not report that it supports the first capability or reports that it does not support the first capability, wherein the fourth capability is that the terminal supports execution of the predetermined communication process based on measurement of a channel state information reference signal CSI-RS within an active BWP.

Case 4: If the reported capability that has no restriction on BWP operation includes the third capability, then the terminal reports that it supports the first capability or the second capability, or the terminal does not report that it supports the first capability or the second capability.

Case 5: If the reported capability that has no restriction on BWP operation includes the third capability, then the terminal reports or does not report that it supports the second capability, but does not report that it supports the first capability or reports that it does not support the first capability.

Case 6: The terminal can only support one of the first capability and the second capability, but cannot support both the first capability and the second capability at the same time.

It is worth noting that the first indication information sent by the network side device to the terminal can be determined according to the capability of unrestricted BWP operation reported by the terminal, such as the target capability enabled by the network side device through the first indication information can be the same as the capability of unrestricted BWP operation reported by the terminal, or, the target capability enabled by the network side device through the first indication information is within the scope of the capability of unrestricted BWP operation reported by the terminal.

Further, when the terminal reports its own capability of unrestricted BWP operation to the network side device, the capability of unrestricted BWP operation includes the first capability or the second capability, and there is no reference signal in the active BWP of the terminal (such as the network side device does not configure any reference signal in the active BWP of the terminal), the network side device can configure a measurement reference signal for the terminal outside the active BWP of the terminal, and the measurement reference signal satisfies any one of the following (21)-(23). The measurement reference signal is used for signal measurement in the predetermined communication process.

(21) The measurement reference signal can only be the first reference signal, such as CD-SSB.
