The rate matching method and device provided by the embodiments of the present application will be described in detail below through specific embodiments and application scenarios with reference to the accompanying drawings.

As shown in FIG. 2, an 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: information for determining whether the first reference signal is available, the available duration of the first reference signal, the unavailable duration of the first reference signal, and first configuration information.

The first reference signal mentioned in the various embodiments of this application may include at least one of the following: a tracking reference signal (Tracking Reference Signal, TRS), a channel state information reference signal (Channel State Information-Reference Signal, CSI-RS), a positioning reference Signals (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 (eg servingcellconfigcommon). For example, the first reference signal is configured by at least one of SIB, RRC release (release), and RRC resume (resume) signaling. For another example, when the first reference signal includes a PRS, the configuration information of the PRS may be acquired through a Positioning System Message (PosSIB).

It should be noted that, unless otherwise specified, the terminal types applicable to the embodiments of this specification include at least one of the following: a connected state terminal, an idle state (idle) terminal, and an inactive state (inactive) terminal.

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

The above-mentioned 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, and RRC related signaling. The RRC related signaling may be one or more of dedicated RRC signaling, RRC release signaling, and RRC resume signaling.

For the above-mentioned information for determining whether the first reference signal is available, for example, the information indicates whether the first reference signal is available in a disconnected state, the information indicates whether the first reference signal is available in a connected state, and the like. In the case where the first information is information for determining whether the first reference signal is available, in S202, the terminal may obtain the information for determining whether the first reference signal is available based on at least one of the following approaches: the terminal blindly checks 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 (eg, whether a paging PDCCH is received).

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

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

S204: Determine, according to the first information, whether to perform rate matching on a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) for the first reference signal, where the first reference signal is configured to be used by a terminal in a non-connected state.

The determination of whether to perform PDSCH rate matching on the first reference signal mentioned in the various embodiments of this specification may also be referred to as: determining whether the resource 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, whether to perform PDSCH rate matching on the first reference signal can be determined based on the first information, so as to flexibly and dynamically improve the utilization rate of the resources occupied by the first reference signal, reduce the resource overhead caused by the first reference signal for PDSCH transmission, and improve the system efficiency. throughput.

In this embodiment, when it is determined to perform PDSCH rate matching 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 a connected state, PDSCH rate matching can be performed on the first reference signal; when the terminal is in a disconnected state, PDSCH rate matching can still be performed on the first reference signal .

The rate matching types of PDSCH 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 capability, PDSCH type, network side device configuration, protocol agreement, and the like.

For example, if the terminal only supports the semi-static rate matching type, the terminal can only perform rate matching on the first reference signal through the semi-static PDSCH rate matching method. For another example, the network-side device configuration or protocol stipulates that semi-static rate matching is performed for the above-mentioned first reference signal, and the terminal can only implement rate matching for the first reference signal in a semi-static rate matching manner.

In the rate matching method provided by this embodiment of the present application, the terminal acquires first information, where the first information includes at least one of the following: information for determining whether the first reference signal is available, the available duration of the first reference signal, and the unavailable duration of the first reference signal The time is used to configure the first configuration information of the first reference signal; and whether to perform PDSCH rate matching on the first reference signal is determined according to the first information, wherein the first reference signal is configured to be used by a terminal in a non-connected state. The embodiments of the present application provide a solution for whether the terminal can perform PDSCH rate matching for 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 device, 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 the unnecessary PDSCH resource overhead caused by the rate matching of the first reference signal even when it is unavailable, and improves the data transmission rate and system throughput.

The embodiments of the present application can reduce the PDSCH resource overhead caused by performing 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 equipment can determine when and how to target the first reference signal. A consistent understanding of PDSCH rate matching is performed to 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, the following will be described with reference to several specific examples.

Example 1

When the first information includes the information for determining whether the first reference signal is available, 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 items :

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

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

The above scheme according to whether the first reference signal can be used 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) and cause the problem of resource waste, and improve the system throughput.

Embodiment 2

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

1) During 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, the resources occupied by the first reference signal cannot be used; for PDSCH transmission.

2) During the unavailable duration of the first reference signal, it is determined not to perform PDSCH rate matching on the first reference signal, that is, during 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 may be used to determine the available duration of the first reference signal, and the time outside the available duration may be referred to as the unavailable duration; the first reference signal unavailable duration 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, and effectively improve the system throughput.

Embodiment 3

When the first information includes the first configuration information, the determining, according to the first information, whether to perform PDSCH rate matching on the first reference signal 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, if the terminal does not receive the first configuration information, it can be understood that the network-side device has not configured the first reference signal for it, and therefore does not 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 (eg, 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 directly determines whether to perform PDSCH rate matching based on whether the network-side device is configured with the first reference signal. 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 system throughput. .

The foregoing three embodiments are all information to determine whether the first reference signal is available, the available duration of the first reference signal, the unavailable duration of the first reference signal, and the first configuration information, at least one of these four types of information. to determine whether to perform PDSCH rate matching on the first reference signal. In fact, two or more pieces of information can also be combined to determine whether to perform PDSCH rate matching on the first reference signal. See Embodiment 4 below. .

Embodiment 4

After the first configuration information is received, and the first information further includes the information for determining whether a first reference signal is available, the first reference signal is available for a duration, and the first reference signal is unavailable for a duration In the case of any one of the above, the determining 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 that the rate matching of the PDSCH is not performed 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, it is determined not to perform PDSCH rate matching on the first reference signal.

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

Optionally, in each of the foregoing embodiments, when the terminal is in a disconnected state, the PDSCH is scheduled by first downlink control information (Downlink Control Information, DCI), and the first DCI is scheduled by any one of the following Scrambling: System Information Radio Network Temporary Identifier (SI-RNTI), Paging Radio Network Temporary Identifier (P-RNTI), Temporary Cell Radio Network Temporary Identifier (TC-RNTI), Random Access Radio Network Temporary Identifier (RA) -RNTI), Message B Radio Network Temporary Identity (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 on 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 PDSCH transmission scheduled by the first DCI. For example, the first reference signal configured by the network for measurement by the terminal in the 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 a 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 foregoing embodiments, in other embodiments, the effect of PDSCH rate matching can also be achieved by restricting the scheduling of network-side devices. When using an 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, when 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 items it's usable or not:

1) Paging the 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 the paging PDCCH, for example, when the terminal is in a connected state, receiving the paging PDCCH, 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 disconnected state, receiving the paging PDCCH, where the paging PDCCH includes an indication of whether the first reference signal is available .

The implicit condition of this example is that the terminal still needs to receive the paging PDCCH after the terminal enters the connected state, and the paging PDCCH indicates whether the first reference signal (eg 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 indication of whether the first reference signal in the paging PDCCH is available.

It can be understood that when the terminal is in the RRC disconnected state, it must receive the paging PDCCH, and when the terminal is in the connected state, whether it needs to receive the paging PDCCH is configured according to 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 by paging the 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, where the paging message includes the determining of the first reference signal. 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 of this example is that the terminal still needs to receive the paging message after entering the connected state, and the paging message indicates whether the first reference signal (eg 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 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, whether it needs to receive the paging message is configured according to the network side. 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 (PEI).

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

The implicit condition of this example is that the terminal still needs to receive the paging advance indication after entering the connected state, and the paging advance indication indicates whether the first reference signal (eg 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 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 the terminal in the connected state not 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 implicitly obtained through the paging advance indication indicating whether to monitor the paging PDCCH. The information for determining whether the first reference signal is available is to determine whether the first reference signal is available in the connected state or the disconnected state according to whether the terminal is in the connected state or the disconnected state.

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

It can be understood that if the network side equipment configures the connected terminal not to monitor the paging advance indication, the information to determine whether the first reference signal is available cannot be implicitly obtained through the paging advance indication indicating whether to monitor the paging PDCCH.

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 the MAC CE includes: when the terminal is in a connected state, receiving the RRC or the MAC CE, the RRC or the MAC CE includes an indication of whether the first reference signal is available.

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

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

In an example, the network side device configuration or protocol agreement configures the first reference signal used in the disconnected state as a semi-static first reference signal resource used by the connected state terminal, and activates or deactivates it through MAC CE signaling The above-mentioned 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 to be used in the connected state. In addition, if the terminal in the connected state switches the BWP, the terminal needs to receive the new MAC-CE signaling for activation or deactivation of the first reference signal.

6) 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 that uplink channel or signal transmission is performed 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), the first semi-static flexible symbol is set as a flexible symbol and/or an uplink symbol according to the DCI format 2_0 indication, or, according to the DCI indication, on the first semi-static flexible symbol 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 to set the first semi-static flexible symbol as a flexible symbol and/or an uplink symbol, or, the DCI In a case where at least one of uplink channel or signal transmission is indicated on the first semi-static flexible symbol, it is determined that the first reference signal is unavailable.

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

Optionally, when the terminal is in a 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.

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

Example 1: Whether the first reference signal can be used for the secondary cell activation measurement indication is added to at least one of the 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-mentioned embodiments, according to the reception of the paging PDCCH or the paging advance indication or the paging message on the primary cell (PCell). to determine whether the first reference signal is available or not. For example, if the PDCCH received on the primary cell indicates that the first reference signal is available, the indication content of whether the first reference signal can be used for the secondary cell activation measurement indication is that the first reference signal can be used for secondary cell activation.

If the first reference signal is available for secondary cell activation measurement indicates that the first reference signal is available for secondary cell activation, the first reference signal is used for secondary cell activation measurement. If whether the first reference signal is available for secondary cell activation measurement indicates that the first reference signal is not available for secondary cell activation or whether the first reference signal is available for secondary cell activation measurement indication is not received, the first reference signal is not used for secondary cell activation measurement Cell activation measurements.

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 to determine whether the first reference signal is available. If the first reference signal is determined to be available The availability information indicates that the first reference signal is available, then 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 be used.
