As shown in FIG. 2 , the embodiment of the present application provides a rate matching method 200, which can be executed by a terminal, in other words, the method can be executed by software or hardware installed in the terminal, and the method includes the following steps.

S202: Acquire first information, where the first information includes at least one of the following items: information for determining whether the first reference signal is available, duration of availability of the first reference signal, duration of unavailability of the first reference signal, and first configuration information.

The first reference signal mentioned in various embodiments of the present application may include at least one of the following: tracking reference signal (Tracking Reference Signal, TRS), channel state information reference signal (Channel State Information-Reference Signal, CSI-RS), positioning reference signal (Positioning Reference Signals, PRS). The first reference signal resource may be configured through system information block (System Information Blocks, SIB) configuration and/or terminal-specific radio resource control (Radio Resource Control, RRC) signaling (such as servingcellconfigcommon). For example, the first reference signal is configured through at least one of SIB, RRC release (release), and RRC resume (resume) signaling. For another example, when the first reference signal includes a PRS, configuration information of the PRS may be obtained through a positioning system message (PosSIB).

It should be noted that, if not specifically stated, the terminal types applicable to the embodiments of this specification include at least one of the following: a terminal in a connected state, a terminal in an idle state, and a terminal in an inactive state.

In this embodiment of the specification, the idle state and the inactive state are collectively referred to as a non-connected state. In this embodiment, the first reference signal is configured for use by a terminal in a non-connected state. The disconnected state means that the RRC is in the disconnected state. The terminal in the non-connected state may be an idle terminal in the RRC idle state, or an inactive terminal in the RRC inactive state. For example, the network side device is configured to share the TRS/CSI-RS originally used by the RRC connected terminal to the non-connected terminal.

The above first configuration information is used to configure the first reference signal, and the first configuration information may be carried by at least one of the following signaling: SIB, RRC related signaling. Wherein, the RRC-related signaling may be one or more of dedicated RRC signaling, RRC release signaling, and RRC resume signaling.

Regarding the information for determining whether the first reference signal is available, for example, the information indicates whether the first reference signal is available in the unconnected state, the information indicates whether the first reference signal is available in the connected state, and so on. In the case where the first information is information for determining whether the first reference signal is available, in S202, the terminal may obtain information for determining whether the first reference signal is available based on at least one of the following approaches: the terminal blindly detects whether the first reference signal is available; The network side device indicates whether the first reference signal is available; the terminal determines whether the first reference signal is available based on a preset condition (such as whether the paging PDCCH is received).

In this embodiment, the available duration of the first reference signal may be indicated by the indication of the available duration of the first reference signal, or may be indicated by the indication of the unavailable duration of the first reference signal. Wherein, the time outside the first reference signal available duration may be the first reference signal unavailable duration; the time outside the first reference signal unavailable duration may be the first reference signal available duration.

In addition, the duration of availability of the first reference signal may include two contents: 1, indicating that the first reference signal is available; 2, indicating the duration of availability of the first reference signal. Similarly, the unavailable duration of the first reference signal may also include two contents: 1, indicating that the first reference signal is unavailable; 2, indicating the unavailable duration of the first reference signal.

S204: According to the first information, determine whether to perform rate matching on a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) for a first reference signal, where the first reference signal is configured for use by a terminal in an unconnected state.

The determination whether to perform PDSCH rate matching on the first reference signal mentioned in various embodiments of this specification may also be referred to as: determining whether the resources occupied by the first reference signal can be used for PDSCH transmission. Specifically, for example, when it is determined to perform PDSCH rate matching on the first reference signal, the resources occupied by the first reference signal cannot be used for PDSCH transmission; when it is determined not to perform PDSCH rate matching on the first reference signal, the resources occupied by the first reference signal Resources are available for PDSCH transmission. In this way, the first information can be used to determine whether to perform PDSCH rate matching on the first reference signal, so as to flexibly and dynamically improve the utilization rate of resources occupied by the first reference signal, reduce the resource overhead caused by the first reference signal for PDSCH transmission, and improve system performance. throughput.

In this embodiment, when it is determined that the PDSCH rate matching is performed on the first reference signal, the step of performing PDSCH rate matching on the first reference signal may also be performed.

In this embodiment, when the terminal is in the connected state, the rate matching of the PDSCH can be performed on the first reference signal; when the terminal is in the unconnected state, the rate matching of the PDSCH can still be performed on the first reference signal .

Wherein, the PDSCH rate matching type may include two types: semi-static rate matching and dynamic rate matching. Which type of rate matching to use may be determined according to at least one of the following: terminal rate matching-related capabilities, PDSCH type, network-side device configuration, protocol agreement, and the like.

For example, if the terminal only supports the semi-static rate matching type, then the terminal can only perform rate matching on the first reference signal through the semi-static PDSCH rate matching method. For another example, if the network-side device is configured or agreed to perform semi-static rate matching on the first reference signal, the terminal can only implement rate matching on the first reference signal in a semi-static rate matching manner.

In the rate matching method provided in the embodiment of the present application, the terminal acquires first information, and the first information includes at least one of the following items: information for determining whether the first reference signal is available, the duration of the availability of the first reference signal, and the duration of unavailability of the first reference signal time, used to configure first configuration information of the first reference signal; and determine whether to perform PDSCH rate matching on the first reference signal according to the first information, where the first reference signal is configured for use by a terminal in a non-connected state. The embodiment of the present application provides a solution for whether the terminal can perform PDSCH rate matching on the first reference signal resource, so as to avoid problems such as transmission and interference caused by inconsistent understanding between the terminal and the network side equipment, and improve communication reliability.

In addition, in the embodiment of the present application, when it is determined not to perform PDSCH rate matching on the first reference signal, the resources occupied by the first reference signal can be used for PDSCH transmission. This further reduces unnecessary PDSCH resource overhead caused by still performing rate matching on the first reference signal when it is unavailable, and improves the data transmission rate and system throughput.

The embodiment of the present application can reduce the PDSCH resource overhead caused by PDSCH rate matching on the first reference signal, improve the data transmission rate and system throughput, and can also ensure that the terminal and the network side device know when and how to target the first reference signal Perform PDSCH rate matching to understand consistency and improve communication reliability.

In order to describe in detail how the terminal determines whether to perform PDSCH rate matching on the first reference signal according to the first information in S204 of Embodiment 200, several specific examples will be used for illustration below.

Embodiment one

In the case where the first information includes the information for determining whether the first reference signal is available, the determining whether to perform PDSCH rate matching for the first reference signal according to the first information includes at least one of the following :

1) If the first reference signal is available, it is determined to perform PDSCH rate matching on the first reference signal, that is, resources occupied by the first reference signal cannot be used for PDSCH transmission.

2) If the first reference signal is unavailable, determine not to perform PDSCH rate matching on the first reference signal, that is, resources occupied by the first reference signal can be used for PDSCH transmission.

The above scheme based on whether the first reference signal is available to determine whether to perform PDSCH rate matching on the first reference signal can solve the problem of still performing PDSCH rate matching when the first reference signal is unavailable (that is, not on the first reference signal resource). PDSCH transmission) causes waste of resources, improving system throughput.

Embodiment two

In a case where the first information includes the duration of availability of the first reference signal or the duration of unavailability of the first reference signal, according to the first information, determining whether to perform The rate matching of PDSCH includes at least one of the following:

1) Within the available duration of the first reference signal, determine to perform PDSCH rate matching on the first reference signal, that is, within the available duration of the first reference signal, resources occupied by the first reference signal cannot be used transmitted on PDSCH.

2) During the unavailable duration of the first reference signal, determine not to perform PDSCH rate matching on the first reference signal, that is, within the unavailable duration of the first reference signal, the resources occupied by the first reference signal Can be used for PDSCH transmission.

In this embodiment, the available duration of the first reference signal can be used to determine the available duration of the first reference signal, and the time outside the available duration can be called the unavailable duration; the unavailable duration of the first reference signal The time may be used to determine the unavailable duration of the first reference signal, and the time outside the unavailable duration may be referred to as the available duration.

The above scheme of determining whether to perform PDSCH rate matching on the first reference signal according to the available/unavailable duration of the first reference signal can solve the waste of resources caused by still performing PDSCH rate matching during the unavailable duration of the first reference signal problem, effectively improving system throughput.

Embodiment three

In the case where the first information includes first configuration information, the determining whether to perform PDSCH rate matching on the first reference signal according to the first information includes at least one of the following:

1) If the first configuration information is received, determine to perform PDSCH rate matching on the first reference signal. For example, if the first configuration information is received in S202, then S204 may directly perform PDSCH rate matching on the first reference signal.

2) If the first configuration information is not received, determine not to perform PDSCH rate matching on the first reference signal. In this example, the terminal does not receive the first configuration information, it can be understood that the network side device does not configure the first reference signal for it, so there is no need to perform PDSCH rate matching on the first reference signal. Specifically, for example, if the SIB is not configured with the first reference signal (such as the first TRS/CSI-RS), the rate matching of the PDSCH is not performed on the first TRS/CSI-RS.

In this embodiment, the terminal determines whether to perform PDSCH rate matching directly by whether the network side device configures the first reference signal for it. The available duration of the reference signal and the unavailable duration of the first reference signal indicate that the signaling overhead is reduced, but at the same time, this static configuration method increases the resource overhead of the first reference signal, which is not conducive to PDSCH transmission and improves system throughput. .

The above three embodiments all use the information for determining whether the first reference signal is available, the duration of the availability of the first reference signal, the duration of the unavailability of the first reference signal, and the first configuration information, at least one of the four types of information To determine whether to perform PDSCH rate matching on the first reference signal, in fact, two or more information can also be combined to determine whether to perform PDSCH rate matching on the first reference signal, see Embodiment 4 below .

Embodiment four

After receiving the first configuration information, and the first information also includes the information for determining whether the first reference signal is available, the duration of availability of the first reference signal, and the duration of unavailability of the first reference signal In any case, the determination of whether to perform PDSCH rate matching on the first reference signal includes at least one of the following:

1) If the first reference signal is available, determine to perform PDSCH rate matching on the first reference signal;

2) If the first reference signal is unavailable, determine not to perform PDSCH rate matching on the first reference signal;

3) within the available duration of the first reference signal, determine to perform PDSCH rate matching on the first reference signal;

4) During the unavailable duration of the first reference signal, determine not to perform PDSCH rate matching on the first reference signal.

Of course, in other embodiments, the first information may include the first configuration information, information for determining whether the first reference signal is available, and an indication of the available duration of the first reference signal. For example, the terminal receives the first configuration information according to the above first information and obtains the indication of availability and duration of the first reference signal, then performs PDSCH on the first reference signal within the duration of availability of the first reference signal. rate matching.

Optionally, in the foregoing embodiments, when the terminal is in a non-connected state, the PDSCH is scheduled by first downlink control information (Downlink Control Information, DCI), and the first DCI is scheduled by any of the following Items are scrambled: System Information Radio Network Temporary Identity (SI-RNTI), Paging Radio Network Temporary Identity (P-RNTI), Temporary Cell Radio Network Temporary Identity (TC-RNTI), Random Access Radio Network Temporary Identity (RA -RNTI), message B radio network temporary identifier (Msg.B-RNTI).

In this embodiment, when the terminal is in the RRC disconnected state, it can still be determined according to the first information whether to perform rate matching of the PDSCH scheduled by the first DCI for the first reference signal, that is, to determine the first reference signal Whether the occupied resource can be used for the transmission of the PDSCH scheduled by the first DCI. For example, the first reference signal configured by the network for measurement by a terminal in a non-connected state is TRS/CSI-RS. The first information includes: first configuration information and information for determining whether the first reference signal is available. When the terminal is in the disconnected state, after receiving the first configuration information, the terminal determines whether the TRS/CSI-RS resource can be used for the P-RNTI according to the received information for determining whether the first reference signal is available Transmission of scrambled PDSCH.

It can be understood that in parallel with the previous embodiments, in other embodiments, the effect of PDSCH rate matching can also be achieved by restricting the scheduling of network-side equipment, for example, the network-side equipment schedules PDSCH/physical During the uplink shared channel (Physical Uplink Shared Channel, PUSCH), it is necessary to avoid the resource location where the first reference signal is located, so as to achieve the effect of rate matching.

Optionally, in embodiment 200, where the first information includes the information for determining whether the first reference signal is available, embodiment 200 may further include: determining the first reference signal according to at least one of the following it's usable or not:

1) Paging a physical downlink control channel (Physical Downlink Control Channel, PDCCH).

In this example, determining whether the first reference signal is available includes: determining whether the first reference signal is available according to a paging PDCCH, specifically, for example, receiving the paging PDCCH when the terminal is in a connected state, The paging PDCCH includes an indication of whether the first reference signal is available.

In the above example, determining whether the first reference signal is available further includes: when the terminal is in a non-connected state, receiving the paging PDCCH, where the paging PDCCH includes an indication of whether the first reference signal is available .

The implicit condition in this example is: after the terminal enters the connected state, it still needs to receive the paging PDCCH, and the paging PDCCH indicates whether the first reference signal (such as TRS/CSI-RS) is available. In this way, the terminal can determine whether to perform PDSCH rate matching on the resources of the first reference signal according to the availability indication of the first reference signal in the paging PDCCH.

It can be understood that when the terminal is in the RRC unconnected state, it must receive the paging PDCCH, and when the terminal is in the connected state, it is necessary to receive the paging PDCCH according to the configuration of the network side. If the network side device configures that the terminal in the connected state does not need to monitor the paging PDCCH, the information for determining whether the first reference signal is available cannot be obtained through the paging PDCCH.

2) Paging message.

In this example, determining whether the first reference signal is available according to the paging message includes: when the terminal is in a connected state, receiving the paging message, the paging message including the determination of the first Information about whether the reference signal is available.

In the above example, determining whether the first reference signal is available further includes: when the terminal is in a disconnected state, receiving the paging message, where the paging message includes an indication of whether the first reference signal is available .

The implicit condition in this example is: after the terminal enters the connected state, it still needs to receive the paging message, and the paging message indicates whether the first reference signal (such as TRS/CSI-RS) is available. In this way, the terminal can determine whether to perform PDSCH rate matching on the resource of the first reference signal according to the indication of whether the first reference signal is available in the paging message.

It can be understood that the paging message can be understood as paging the PDSCH scheduled by the PDCCH. When the terminal is in the RRC disconnected state, it needs to try to receive the paging message, and when the terminal is in the connected state, it is necessary to receive the paging message according to the network side configuration. If the network side device configures that the terminal in the connected state does not need to monitor the paging message, the indication of whether the first reference signal is available cannot be obtained through the paging message.

3) Paging Early Indication (Paging Early Indication, PEI).

In this example, determining whether the first reference signal is available according to the paging advance indication includes: receiving the paging advance indication when the terminal is in a connected state, where the paging advance indication includes the an indication of whether the first reference signal is available;

In the above example, determining whether the first reference signal is available further includes: when the terminal is in a disconnected state, receiving the paging advance indication, where the paging advance indication includes whether the first reference signal Instructions available.

The implicit condition in this example is: after the terminal enters the connected state, it still needs to receive the paging advance indication, and the paging advance indication indicates whether the first reference signal (such as TRS/CSI-RS) is available. In this way, the terminal can determine whether to perform PDSCH rate matching on the resource of the first reference signal according to the indication of whether the first reference signal is available in the paging advance indication.

It can be understood that if the network side device configures that the terminal in the connected state does not need to monitor the paging advance indication, the information for determining whether the first reference signal is available cannot be obtained through the paging advance indication.

4) The paging advance indication indicates whether to monitor the paging PDCCH.

In this example, the information for determining whether the first reference signal is available is obtained implicitly by using the paging advance indication to indicate whether to monitor the paging PDCCH. The information for determining whether the first reference signal is available determines whether the first reference signal is available in the connected state or the unconnected state according to whether the terminal is in the connected state or the unconnected state.

In this example, according to the paging advance indication indicating whether to monitor the paging PDCCH, determining whether the first reference signal is available includes at least one of the following: if the paging advance indication indicates monitoring the paging PDCCH, determining the first The reference signal is available; if the paging advance indication indicates that the paging PDCCH is not monitored, it is determined that the first reference signal is not available.

It can be understood that if the network-side device configures that the terminal in the connected state does not need to monitor the paging advance indication, it cannot use the paging advance indication to indicate whether to monitor the paging PDCCH to implicitly obtain information for determining whether the first reference signal is available.

5) Radio Resource Control (Radio Resource Control, RRC) or Media Access Control-Control Element (Media Access Control-Control Element, MAC CE).

In this example, determining whether the first reference signal is available according to the RRC or MAC CE includes: when the terminal is in a connected state, receiving the RRC or the MAC CE, the RRC or the MAC The CE includes an indication of whether the first reference signal is available.

Optionally, in this example, RRC or MAC CE may be used to indicate whether the terminal in the connected state can use the first reference signal configured for the terminal in the non-connected state.

In an example, the terminal determines whether to perform PDSCH rate matching on the resources of the first reference signal by receiving the indication of whether the first reference signal carried in RRC or MAC CE is available. This example can be applied to the network side device configuration connection state When the terminal does not need to receive paging PDCCH, paging advance indication or paging message.

In one example, the network-side device configuration or agreement stipulates that the first reference signal used in the unconnected state is configured as a semi-static first reference signal resource for the terminal in the connected state, and is activated or deactivated through MAC CE signaling The aforementioned semi-static first reference signal.

In this example, the effective delay of the first reference signal is different from that of the first reference signal configured for the connected state. In addition, if the terminal in the connected state switches the BWP, the terminal needs to receive the above new MAC-CE signaling for activation or deactivation of the first reference signal.

6) The DCI format 2_0 indicates that the first semi-static flexible symbol is set as a flexible symbol and/or an uplink symbol, and the first semi-static flexible symbol is configured with the first reference signal.

7) The DCI indicates to perform uplink channel or signal transmission on the first semi-static flexible symbol, where the first reference signal is configured on the first semi-static flexible symbol.

Based on the examples of 6) and 7), set the first semi-static flexible symbol as a flexible symbol and/or uplink symbol according to the DCI format 2_0 indication, or set the first semi-static flexible symbol on the first semi-static flexible symbol according to the DCI indication Performing at least one of uplink channel or signal transmission to determine whether the first reference signal is available includes: indicating in the DCI format 2_0 that the first semi-static flexible symbol is set as a flexible symbol and/or an uplink symbol, or, the DCI Indicating that in a case where at least one of uplink channel or signal transmission is performed on the first semi-static flexible symbol, it is determined that the first reference signal is unavailable.

Specifically, for example, in the case that the first reference signal is configured on a semi-static flexible symbol, if a DCI 2-0 dynamic instruction is received to set the above-mentioned semi-static flexible symbol as a flexible symbol or an uplink symbol, or, if a If the DCI indicates that uplink transmission is performed on the semi-static flexible symbol, it is determined that the first reference signal is no longer available.

Optionally, when the terminal is in the connected state, the first reference signal mentioned in embodiment 200 may also be used for at least one of the following: time-frequency synchronization, channel state information (Channel State Information, CSI ) measurement, radio resource management (Radio Resource Management, RRM) measurement, radio link monitoring, beam failure detection, beam management, automatic gain control (Automatic Gain Control, AGC), fast secondary cell activation.

For the embodiment that the first reference signal can be used for fast secondary cell activation of the terminal in the connected state, refer to Example 1 and Example 2.

Example 1: Whether the first reference signal can be used for the secondary cell activation measurement indication is added to at least one item of RRC, MAC CE, and PDCCH signaling carrying the secondary cell activation indication. It should be noted that the specific indication content of whether the added first reference signal can be used for the secondary cell activation measurement indication can be combined with the above embodiment, according to receiving the paging PDCCH or paging advance indication or paging message on the primary cell (PCell) It is determined by the information indicating whether the first reference signal is available or not. For example, if the paging PDCCH received on the primary cell indicates that the first reference signal is available, the indication content of whether the first reference signal is available for secondary cell activation measurement indication is that the first reference signal is available for secondary cell activation.

If whether the first reference signal can be used for secondary cell activation measurement indicates that the first reference signal can be used for assisting secondary cell activation, the first reference signal is used to perform secondary cell activation measurement. If whether the first reference signal can be used for secondary cell activation measurement indicates that the first reference signal is not available for assisting secondary cell activation or if the indication of whether the first reference signal is available for secondary cell activation measurement is not received, the first reference signal is not used for secondary Cell activation measurement.

Example 2: Define a new behavior: monitor the paging PDCCH or paging advance indication on the secondary cell. The paging PDCCH or paging advance indication carries information for determining whether the first reference signal is available. If the first reference signal is determined to be If the information indicating whether the first reference signal is available indicates that the first reference signal is available, the first reference signal can be used for secondary cell activation measurement; if the information for determining whether the first reference signal is available indicates that the first reference signal is unavailable, the first reference signal cannot It is used to perform secondary cell activation measurement.
