Description

Technical Field

[0001] The present disclosure relates to a reference signal availability indication method and apparatus, a network element device, a terminal (UE, User Equipment) and a storage medium. Background Art

[0002] The current 3GPP standardization of the R17 power saving project proposes the use of additional Tracking Reference Signals (TRS) and Channel State Information-Reference Signals (CSI-RS) in idle state to assist users in acquiring time-frequency synchronization with the network. Compared to the original synchronization signal and PBCH block (SSB) synchronization, TRS / CSI-RS configuration can be configured closer to the paging occasion (PO). The original SSB is far from the PO location, so users need to wake up long in advance to synchronize with the SSB. With the additional TRS / CSI-RS, users can wake up later, thereby saving more power.

[0003] It is currently preliminarily believed that system messages will include additional TRS / CSI-RS configuration information, along with information about whether the information is being broadcast. TRS / CSI-RS configuration information can be considered separate from the availability status, meaning that the network may have configured TRS / CSI-RS but not actually transmitted it, meaning it is not available to idle users. According to the latest meeting minutes, this is determined by base station implementation. Based on the current meeting conclusions, TRS / CSI-RS configuration information is placed in the System Information Block (SIB-X).

[0004] Currently, it's assumed that non-connected users must be notified of the broadcast status of TRS / CSI-RS. This is because users need to use valid TRS / CSI-RS information to determine how to synchronize with the network. A mismatch between these two information levels can cause significant problems. For example, if the network is transmitting valid TRS / CSI-RS information but the terminal believes it is not, it will use the existing SSB synchronization method, resulting in significant power consumption. Conversely, if the network stops transmitting valid TRS / CSI-RS information and the terminal continues to synchronize based on the existing understanding, synchronization accuracy will decrease. Therefore, TRS / CSI-RS availability must be explicitly notified to the terminal. Currently, this availability indication is communicated to the terminal via Layer 1 signaling, which may be PEI or Paging DCI. The network also specifies the validity period of the TRS / CSI-RS resource set (e.g., a number of default DRX cycles). The validity period, or reference point, is the first paging frame of the default DRX cycle in which the terminal receives the availability indication.

[0005] After the network indicates the availability of a TRS / CSI-RS resource set, it typically does not issue further availability changes for that TRS / CSI-RS resource set. However, network configurations often change dynamically. For example, if a terminal that provides a TRS / CSI-RS resource set switches, this may involve a TRS / CSI-RS configuration change. However, there is no technical solution for how terminals can uniformly handle configuration changes and availability changes. Summary of the Invention

[0068] According to the technical solution of the embodiments of the present disclosure, a terminal in a first state receives a first indication message sent by the network and uses the reference signal availability status information contained in the first indication message to monitor the reference signal for synchronization. Specifically, after receiving the reference signal availability indication, if a system message change occurs, the terminal can obtain the system message and return the availability status information to the default state. Alternatively, unchanged reference signal resource sets continue to use the previous availability status according to Layer 1 (Lay 1). Alternatively, if both Layer 1 and system message updates occur simultaneously, the reference signal availability status is determined based on the system message and the Layer 1 method. In the embodiments of the present disclosure, even if the reference signal resource set switches and the network no longer sends an availability change indication for the reference signal resource set, the terminal can still monitor the reference signal for the reference signal configuration change and availability status, achieving corresponding synchronization. This embodiment of the present disclosure effectively supplements the use of reference signal availability information, making network access more convenient for terminals.

[0087] Figure 2 FIG. 1 is a flow chart showing a method for indicating the availability of a reference signal according to an exemplary embodiment. Figure 2 As shown, the reference signal availability indication method of the embodiment of the present disclosure is applied to the terminal side. The reference signal availability indication method of the embodiment of the present disclosure includes the following processing steps:

[0088] Step 201: A terminal in a first state receives first indication information sent by a network side.

[0089] In an embodiment of the present disclosure, the first indication information includes reference signal availability status information. The availability status information includes information indicating whether the reference signal is available or unavailable. Specifically, the availability status includes information indicating whether the reference signal has changed in availability; the availability change information includes information indicating whether the reference signal has changed from available to unavailable, or whether the reference signal has changed from unavailable to available.

[0090] The reference signal includes a TRS or a CSI-RS, etc. The first state includes an idle state or an inactive state, etc., that is, the terminal is still in a non-connected state.

[0091] In an embodiment of the present disclosure, when the terminal receives system information or system information change indication information sent by the network side, the terminal obtains the configuration information of the reference signal based on the system information; and listens to the changed reference signal according to the default availability status. Here, although the network side is configured with an indication mechanism for the availability status information of the reference signal, when the terminal receives the system information or system information change indication information sent by the network side, the availability status information of the reference signal is not obtained, and the changed reference signal is listened to according to the default availability status. As a preferred embodiment, the default availability is unavailable. Specifically, the terminal determines at least one reference signal that has been changed based on the configuration information of the reference signal, and confirms that the availability status of at least one reference signal that has been changed is unavailable. That is, when the reference signal does not indicate the availability status information, the default availability status of the reference signal is unavailable.

[0092] In some exemplary embodiments of the present disclosure, the terminal receives system information or system information change indication information sent by the network side, and obtains reference signal configuration information based on the system information; the reference signal availability status continues to use the availability status before the reference signal configuration information is changed. That is, when the configuration information of a reference signal, such as a TRS / CSI-RS resource set group, has not changed, that is, no TRS / CSI-RS resource sets have been added / modified / deleted in the TRS / CSI-RS resource set group, the TRS / CSI-RS availability status is processed according to the pre-change SIB message, that is, it continues to use the validity period sent by the network. If the configuration information of a TRS / CSI-RS resource set group has changed, that is, TRS / CSI-RS resource sets have been added / modified / deleted in the TRS / CSI-RS resource set group, the reference signal availability status is processed according to the post-change SIB message, that is, it is processed according to the default availability status. For example, it enters the initial unavailable state. That is, the validity period sent by the network will become invalid.

[0093] In some exemplary embodiments of the present disclosure, the terminal receives the first indication information and simultaneously receives system information or system information change indication information; the terminal may monitor the reference signal based on the reference signal configuration information and default availability status information. Specifically, when receiving both the system information or system information change indication information and the reference signal availability status information, the terminal will obtain an updated system message at a system message update boundary, and its resource availability will be processed according to the default availability status, i.e., treated as unavailable.

[0094] In some exemplary embodiments of the present disclosure, the terminal receives the first indication information and simultaneously receives system information or system information change indication information; and monitors the reference signal based on the configuration information and availability status information of the reference signal. That is, when both the system information or the system information change indication information and the reference signal availability status information are received, the reference signal monitoring mode is determined by combining the two types of information. For example, the availability status information of the currently received reference signal can be used as the reference signal availability indication. Alternatively, when the reference signal availability indication is unavailable and the reference signal configuration information indicates a reference signal change, the changed reference signal is determined to be available. At this time, the effective reference point or the effective time starting point of the reference signal availability validity period can be calculated from the boundary of the system message update.

[0095] In some exemplary embodiments of the present disclosure, with respect to receiving both system information or indication information of a change to system information and availability status information of a reference signal, the terminal may receive both the system information or indication information of a change to system information and availability status information of a reference signal in the same message, such as Paging DCI. Alternatively, the terminal may receive the first indication information and the system information or indication information of a change to system information through different messages within the same system message modification period. Specifically, the terminal receives the system information or indication information of a change to system information and the availability status information within the same system message modification period, and determines to simultaneously receive the system information or indication information of a change to system information and the availability status information.

[0096] In some exemplary embodiments of the present disclosure, the availability status information of the reference signal is indicated in a bitmap manner, and the number of indication bits in the bitmap is the same as the number of reference signal resource set groups configured in the system information.

[0097] In some exemplary embodiments, the availability status information is carried in a paging downlink control information (DCI) message or a permanent equipment identifier (PEI) DCI message;

[0098] The system information or the change indication information of the system information is carried in a paging DCI message or a PEI DCI message.

[0099] The technical solution of the embodiment of the present disclosure is applicable to terminals in idle state / inactive state; wherein the availability indication includes TRS / CSI-RS available (available) or unavailable (unavailable) information; the availability indication also includes TRS / CSI-RS availability changes, such as from available to unavailable or from unavailable to available.

[0100] If a terminal receives an SIB message carrying TRS / CSI-RS configuration information or an indication of a change in TRS / CSI-RS configuration information, the terminal determines the availability of TRS / CSI-RS resources based on the acquired TRS / CSI-RS configuration information in the following manner:

[0101] Method 1: The availability status is handled as the default, that is, the TRS / CSI-RS resource is considered unavailable. The terminal will fall back to SSB synchronization when it wakes up from sleep mode until it receives the next TRS / CSI-RS availability indication from the network.

[0102] For example, if a terminal has N TRS / CSI-RS resource sets before receiving a system change notification, and the N bits in the bitmap indicate the availability status, and the terminal obtains new TRS / CSI-RS configuration information, for example, M TRS / CSI-RS resource sets (M may be greater than, equal to, or less than N), the availability status of all M TRS / CSI-RS resource sets is considered unavailable. At this time, the original timer used for the validity period is deleted.

[0103] M is greater than N, which means that a new TRS / CSI-RS is added to the TRS / CSI-RS resource set group.

[0104] Method 2: The availability status continues to use the previous availability status after the system message is updated. The validity period of the continued availability status is not affected.

[0105] As an example: if the configuration information of a TRS / CSI-RS resource set group has not changed, that is, there is no addition / modification / deletion of TRS / CSI-RS resource sets in the TRS / CSI-RS resource set group, then its availability status is processed according to the pre-change processing of the SIB message, that is, the previous reference signal availability status information is used;

[0106] As another example, if the configuration information of a TRS / CSI-RS resource set group changes, that is, if a TRS / CSI-RS resource set is added / modified / deleted within the TRS / CSI-RS resource set group, the reference signal availability status is processed according to the pre-change SIB message, that is, the previous reference signal availability status information is retained. Here, as long as the Group ID remains unchanged and is the same as the previous reference signal Group ID, the previous reference signal availability status information can be retained.

[0107] In the case of using the previous reference signal availability status information, the validity duration timer of the availability status information is not affected.

[0108] For example, if Group 0 remains unchanged, Group 1 changes, Group 2 is deleted, and Group 3 is newly added, the availability status of the reference signal for Group 0 remains unchanged from the previous availability status. The effectiveness status of Group 1 and Group 3 is initially invalid, waiting for subsequent activation.

[0109] In the embodiment of the present disclosure, if a terminal receives a change indication of a SIB message carrying TRS / CSI-RS configuration information, and the terminal also receives an availability indication of a TRS / CSI-RS resource, the terminal is processed as follows:

[0110] The change indication of the SIB message and the availability indication of the TRS / CSI-RS resources may be notified to the terminal in the same message: for example, the change indication of the SIB message and the availability indication of the TRS / CSI-RS resources are received in the same Paging DCI. Alternatively, the change indication of the SIB message and the availability indication of the TRS / CSI-RS resources may not be notified to the terminal in the same message: for example, the terminal receives the change indication of the SIB message in one Paging DCI and the availability indication of the TRS / CSI-RS resources in another DCI; alternatively, the change indication of the SIB message and the availability indication of the TRS / CSI-RS resources may not be notified to the terminal in the same message: for example, the change indication of the SIB message is received in one Paging DCI and the availability indication of the TRS / CSI-RS resources is received in another PEI DCI.

[0111] In the embodiment of the present disclosure, the change indication of the SIB message and the availability indication of the TRS / CSI-RS resource are issued within the same system message modification period and can be considered to be received at the same time;

[0112] In this case, the terminal can obtain the availability indication from both the resource configuration indication in the system message and the TRS / CSI-RS resource availability indication. That is, the terminal combines the information in the SIB and Layer 1 indication to jointly determine the reference signal availability. If the reference signal availability indication is unavailable, and the reference signal configuration information indicates a reference signal change, the changed reference signal is determined to be available. If the reference signal availability indication is available, and the reference signal configuration information indicates a reference signal deletion, the changed reference signal is determined to be unavailable.

[0113] At this time, the effective time point will be based on the boundary of the system message update.

[0114] In the embodiment of the present disclosure, the number of bits in the bitmap in the availability indication of the TRS / CSI-RS resource is consistent with the number of TRS / CSI-RS resource set groups configured in the system message; for example, if the TRS / CSI-RS resource set group is configured as 2 Groups, 2 bits are required for the availability indication.

[0115] In an embodiment of the present disclosure, after the terminal obtains an indication of the availability status of a reference signal, if a system message change occurs, the terminal returns to the default state after obtaining the system message; or, the resource set portion of the reference signal that has not changed continues to be processed using the previous availability status in the Lay1 manner; or, in the case where Lay1 and system message updates occur simultaneously, the availability status of the reference signal is comprehensively determined in accordance with the system message and lay1 manner.

[0116] Figure 3 FIG. 1 is a flow chart showing a method for indicating the availability of a reference signal according to an exemplary embodiment. Figure 3 As shown, the reference signal availability indication method of the embodiment of the present disclosure is applied to the network side. The reference signal availability indication method of the embodiment of the present disclosure includes the following processing steps:

[0117] Step 301: The network side sends first indication information, where the first indication information includes availability status information of a reference signal.

[0118] In an embodiment of the present disclosure, the first indication information includes reference signal availability status information. The availability status information includes information indicating whether the reference signal is available or unavailable. Specifically, the availability status includes information indicating whether the reference signal has changed in availability; the availability change information includes information indicating whether the reference signal has changed from available to unavailable, or whether the reference signal has changed from unavailable to available.

[0119] The reference signal includes a TRS or a CSI-RS, etc. The network side includes network element devices such as a base station and a relay station. The terminal receiving the availability change information of the reference signal is a terminal in an idle state / inactive state.

[0120] In some exemplary embodiments of the present disclosure, the network side sends the availability change information and the system information or the system information change indication information through a paging DCI message and / or a PEI DCI message.

[0121] The SIB message change indication and the TRS / CSI-RS resource availability indication may be sent in the same message: for example, the SIB message change indication and the TRS / CSI-RS resource availability indication may be carried in the same Paging DCI. Alternatively, the SIB message change indication and the TRS / CSI-RS resource availability indication may not be carried in the same message: for example, the SIB message change indication may be carried in one Paging DCI, and the TRS / CSI-RS resource availability indication may be carried in another DCI.

[0122] Alternatively, the SIB message change indication and the TRS / CSI-RS resource availability indication may not be carried in the same message: for example, the SIB message change indication is carried in one Paging DCI, and the TRS / CSI-RS resource availability indication is carried in another PEI DCI.
