The availability indication of the preset reference signal for the non-connected UE is sent through a preset message.

The preset message may include various messages sent by the base station. In this embodiment of the present disclosure, the preset message is an availability indication of a preset reference signal delivered to a UE in a disconnected state. Therefore, the preset message may be any message that can be received by any UE in the disconnected state, or any message received by the disconnected UE when it is in the connected state before entering the disconnected state.

In some embodiments, the availability indication includes:

The first type of indication is used to indicate the availability status of whether the preset reference signal is available;

and / or,

The second type of indication is used to indicate the availability change of the configuration of the preset reference signal.

The first type of indication is the indication of the availability state, and the availability indication is to directly indicate whether the configuration of the corresponding preset reference signal is available or unavailable. After receiving the first type of indication, the UE may directly determine whether the configuration of the preset reference signal corresponding to the first type of indication is available according to the first type of indication.

In summary, the availability status includes: an available status indicating available, and/or an unavailable status indicating unavailable.

The second type of indication is an indication indicating the change of the availability state of the configuration of the preset reference signal, that is, the second type of indication is an availability change indication. After receiving the second type of indication, the UE needs to determine whether the configuration of the corresponding preset reference signal is available according to whether the configuration of the preset reference signal corresponding to the second type of indication is currently available, and combined with the availability change.

In summary, the availability change may include: an availability change indicating a change in availability, and/or no change in availability maintaining the current availability.

In some embodiments, there are multiple formats of the availability indication, and at least two optional formats are provided below:

The availability indication includes: a bitmap; wherein, the bitmap includes: one or more indication bits; wherein, one bit of the indication bits is used to indicate a set of configurations of the preset reference signal or, a bit in the first type of indication bits is used to indicate the availability change of a set of configurations of the preset meal card signal.

In the form of a bitmap, the availability of one or more configurations of preset reference signals can be indicated with minimal bit overhead.

If indicated in the form of a bitmap, the configuration of the preset reference signal may be indicated by the bit values "0" and "1" of the bit, respectively carrying the availability or unavailability of the corresponding preset reference signal configuration; or, it may be The indicated bit values "0" and "1" respectively carry whether the availability of the configuration corresponding to the preset reference signal is changed. If the availability is changed, after receiving the bitmap, the UE will change to an availability state opposite to the configuration availability of the corresponding set of preset reference signals according to the availability state of the configuration of the corresponding set of preset reference signals. If the availability does not change, after receiving the bitmap, the UE will maintain the current availability state of the configuration of the corresponding set of preset reference signals.

In one embodiment, the availability indication includes an indication tag (availability value tag); the one indication tag or each indication tag in the plurality of indication tags is used to carry the preset reference signal A set of configuration availability indications.

The value of the indication label may include: 0 and 1, and may also include multiple values such as 0-7, 0-15, or 0-31.

The value of the indication label may be represented by one or more indication bits, and may also be corresponding to different values by different amplitudes and/or different frequencies of the waveform of the modulating signal.

If an indicator tag is used to carry the availability indication of the configuration of the preset reference signal, since the indicator tag may include multiple values, it can be used to indicate that the configuration of the preset reference signal is available, and the remaining part of the value can be used to indicate the availability of the preset reference signal. Configuration not available. Alternatively, a plurality of values in an indication tag can be used to indicate that the availability state of the configuration of the preset reference signal changes, and the remaining values can be used to indicate that the availability state of the configuration of the preset reference signal does not change.

Exemplarily, one of the indication tags includes 32 values, which are 0 to 31 respectively. 1 or 31 of the 32 values can be used to indicate that the availability state has changed, and the remaining values can be used to indicate that the availability state has not changed.

In an embodiment, the preset message may be any message sent by the base station, for example, the preset message may be a physical layer message or a radio link control (Radio Resource Control, RRC) message sent by the base station.

Several optional ways of the preset message are provided below, which may specifically include at least one of the following:

system information;

Scheduling messages for system messages;

Paging message change message.

System messages can be divided into: broadcast system message blocks and ondemand-based system message blocks. The system message carrying the availability indication may include: a broadcasted system message block. In this way, even if the UE enters the cell and misses the availability indication delivered by the paging message change message in the cell, the availability indication can still be received by receiving the broadcasted system message block. If the availability indication is carried in the request-based system message block, if the UE enters the cell and misses the availability indication sent by the base station in other ways (for example, through the paging message change notification), it can pass the system message block. For the acquisition request, request the base station for the ondemand system message block that carries the availability indication of the configuration of the preset reference signal.

The scheduling message of the system message may include DCI for various PDCCH transmissions.

In one embodiment, the system message may include:

main message block MIB;

System message block SIB-Y; wherein, the Y is a positive integer.

The paging message change notification may be a notification message of various arbitrary paging message scheduling or transmission changes.

If Y=1, SIB-Y is SIB-1, and both SIB-1 and MIB are system message blocks broadcast by the base station in the cell.

Exemplarily, the paging message change notification includes but is not limited to:

Paging downlink control information (paging Downlink Control Imformation, Paging DCI);

and / or,

Paging Early Indication (PEI).

In one embodiment, in response to the preset message being a scheduling message of the system message, the availability indication is carried by a reserved bit carried in downlink control information for scheduling the system message. Exemplarily, in response to the preset message being a scheduling message of the system message and the system message being SIB-Y, the availability indication is carried by a reserved bit of downlink control information carried in scheduling SIB-Y.

In one embodiment, the SIB-Y is:

SIB-1;

or,

SIB-X, wherein the X is a positive integer greater than or equal to 2.

In one embodiment, the SIB-X may be SIB-2, SIB-3, SIB-4, or SIB-5, or the like. Exemplarily, the SIB-X may include: a newly introduced SIB, a dedicated SIB carrying the availability indication of the preset reference signal.

Exemplarily, the scrambling sequence of the SIB-1 carrying the availability indication is different from the scrambling sequence of the SIB-1 not carrying the availability indication; or, the scrambling sequence of the SIB-1 carrying the availability indication. The scrambling sequence is different from the scrambling sequence of SIB-Z1, where Z1 is a positive integer not equal to 1.

Exemplarily, the scrambling sequence of the SIB-X carrying the availability indication and the scrambling sequence of the SIB-X not carrying the availability indication are different; or, the SIB-X carrying the availability indication and the SIB-Z2 The scrambling sequences are different; the Z2 is a positive integer not equal to the X.

The SIB-X here is that the SIB proposed in the related art is multiplexed to carry the availability indication, and it may also be a newly proposed SIB. In an embodiment, the SIB-X, wherein the X is a positive integer greater than or equal to 2; the SIB-X is the scheduled physical downlink scrambled by the first system message SI-wireless network temporary identifier RNTI The SIB of the shared channel PDSCH carries the availability indication; the SIB-X of the scheduling PDSCH scrambled by the second SI-RNTI does not carry the availability indication. That is, the SIB-X, where the X is a positive integer greater than or equal to 2; in response to the SIB-X carrying the availability indication, the scheduling information of the PDSCH carried by the SIB-X is determined by the A system message SI-Wireless Network Temporary Identity RNTI is scrambled; in response to the SIB-X not carrying the availability indication, the scheduling information of the PDSCH carried by the SIB-X is scrambled by the second SI-RNTI. SI-RNTI and the first SI-RNTI.

In one embodiment, the SIB-X may be an existing SIB in the related art, and the SIB-X includes scheduling information of the PDSCH, and the scheduling information of the PDSCH may be scrambled by the first SI-RNTI. The SIB-X of the scheduling information of the PDSCH scrambled by the first SI-RNTI is carried; the SIB-X of the scheduling information of the PDSCH scrambled by the second SI-RNTI does not carry the aforementioned availability indication.

In some cases, the second SI-RNTI may be the SI-RNTI that has been used to scramble the SIB-X in the related art; and the first SI-RNTI is a newly proposed SI-RNTI that is different from the SI-RNTI.

Exemplarily, the first SI-RNTI and the second SI-RNTI are different, and after the UE receives the corresponding SIB, if the first SI-RNTI is successfully descrambled, it is considered that the currently received SIB-X carries the Availability indication; if descrambling is successful through the second SI-RNTI, it may be considered that the currently received SIB-X does not carry the availability indication.

In other embodiments, the SIB-X is the SIB of the scheduled physical downlink shared channel PDSCH scrambled by the third SI-RNTI, and carries the availability indication; the SIB of the scheduled PDSCH scrambled by the fourth SI-RNTI -Z does not carry the availability indication; the Z is a positive integer not equal to the X.

For example, SIB-X may be a newly proposed SIB that may be used to carry the availability indication. SIB-Z may include SIB-Z other than SIB-X mentioned in the related art. SIB-Z and SIB-X are scrambled with different SI-RNTIs.

Exemplarily, the fourth SI-RNTI and the third SI-RNTI are different.

In short, SIB-X and SIB-Z other than SIB-X are scrambled with different SI-RNTIs, which is convenient for the UE to quickly determine whether that SIB carries an availability indication according to the successful scrambled sequence after receiving it.

The availability indication may be explicitly carried by the indication bit, or may be used to be indicated implicitly.

For example, one or more indication bits are carried in SIB-Y, and these indication bits specifically carry the availability indication.

For another example, the availability indication is implicitly indicated by whether a certain piece of information in SIB-Y has a corresponding relationship between the carrying and the availability indication.

Therefore, in some embodiments, the SIB-1 implicitly indicates the availability indication by whether it includes scheduling information of the SIB-X;

The SIB-X implicitly indicates the availability indication according to whether the configuration of the preset reference signal is included. If the configuration of the preset reference signal is placed in the SIB-1, the availability indication may be implicitly indicated by whether the configuration of the preset reference signal is included in the SIB-1.

After receiving the SIB-Y that implicitly indicates the availability indication, the UE may determine the availability indication of the current configuration of the preset reference signal according to any of the above-mentioned correspondences.

In some embodiments, the SIB-X included in the SIB-Y is further used to carry the configuration of the preset reference signal, where the X is a positive integer greater than or equal to 2.

Different sets of preset reference signals are configured, and at least part of the time-frequency resources for transmitting the preset reference signals are different.

For example, for the configurations of preset reference signals for different types of UEs, the used time-frequency resources are at least partially different, so it can be considered as the configuration of two sets of preset reference signals.

In some embodiments, when the availability indication carried in the system message or the scheduling message of the system message changes, the system message update process is not triggered. Exemplarily, when the availability indication carried by the SIB-Y is changed, the system message update process is not triggered. Exemplarily, when the availability indication carried by the SIB-Y is changed, the update of the indication label of the SIB-Y is not triggered.

That is, when the UE receives the change carrying the availability indication, the UE will not be triggered to initiate the system message update process, so as to initiate a message request for obtaining the updated system message.

In a word, the system message may carry the availability indication explicitly by means of an indication bit; or, carry the availability indication by means of an implicit indication.

The availability indication may be the aforementioned indication of availability status and/or indication of availability change.

Exemplarily, when the availability indication carried in the system message or the scheduling message of the system message changes, the system message update process is not triggered. Exemplarily, when the indication label of the availability indication carried by the SIB-Y is changed, the system message update process is not triggered.

In one embodiment, the paging message change notification is used to carry a second type of indication indicating a change in availability of the preset reference signal.

The paging message change notification can be physical layer signaling. The physical layer signaling has fewer bits, and the availability change can be carried as little as possible, so that the availability indication can be implemented with as few bits as possible.

In one embodiment, the paging message change notification carries a bitmap; the bitmap includes one or more bits; wherein one of the bits is used to indicate a set of the preset reference signals Availability changes to the configuration.

In one embodiment, the paging message change notification carries the availability indication of the availability change of the configuration of the preset reference signal; wherein the changed availability indication of the multiple sets of configurations of the preset reference signal is determined by the The system message or the scheduling message of the system message is carried.

Here, through the paging message change notification, the overall availability of multiple sets of preset reference signal configurations carried is changed; it is equivalent to informing the UE that the availability of at least one set of preset reference signal configurations has changed, and the changed sets of preset reference signals The availability of the configuration of the reference signal may be carried by a system message or a system message scheduling message.

In some embodiments, the paging downlink control information may be any message transmitted on the resources scheduled by the base station to deliver the paging DCI. Exemplarily, according to whether the paging downlink control information carries the availability indication, the paging downlink control information may include two types: the first type of paging downlink control information is the paging DCI that does not carry the availability indication, and the second type of paging downlink control information carries the paging DCI. paging DCI with availability indication.

In view of this, the paging downlink control information carrying the availability indication is the second type of paging downlink control information, wherein the second type of paging downlink control information is different from the first type of paging downlink control information that does not carry the availability indication. A type of paging downlink control information.

The first type of paging downlink control information may be paging DCI provided in the related art, where the paging DCI carries at least one of short messages and/or scheduling messages of paging messages delivered to the UE.

The second type of paging downlink control information may carry either short message and/or paging message scheduling message indication, or may not carry at least one of the short message and/or paging message scheduling message, but At least one of the availability indication and/or configuration change of the preset reference signal is carried.

In some embodiments, the formats of the first type of paging DCI and the second type of paging DCI may be the same or different. For example, the second type of paging DCI may follow the message format used for the scheduling message carrying the short message and/or the paging message in the related art, or may specify a completely new message format.

In other embodiments, the second type of paging DCI can continue to use the message format of the first type of paging DCI, but the content carried by each bit in the message format can be redefined. The availability indication and/or configuration change of the preset reference signal carried by the paging DCI may be carried at any position in the message format even if the message format is the same as that of the first type of paging DCI.

In order to distinguish the two types of paging messages, the second type of paging DCI and the first type of paging DCI can be scrambled with different scrambling sequences. In this way, the UE can distinguish between the different sequences used for descrambling after receiving it. Whether the currently received paging DCI is the first type paging DCI or the second type paging DCI.

In one embodiment, the second type of paging downlink control information can be a newly added type of paging downlink control information. Exemplarily, the second type of paging downlink control information can be used to carry the aforementioned availability indication exclusively. .

In an embodiment, the second type of paging downlink control information includes: an indication field and a message field. In some cases, the indication field is usually used to indicate the content carried by the message field. At least one of the indication field and the message field contains one or more bits. Illustratively, the message field contains more bits than the indication field.

In some cases, the message formats of the second type of paging downlink control information and the first type of paging downlink control information are the same, and the number of bits contained in the indication field of the second type of paging downlink control information is the same as that of the first type of paging downlink control information. The number of bits contained in the downlink control information is the same; and the number of bits contained in the message field of the second type of paging downlink control information is the same as the number of bits contained in the first type of paging downlink control information.

In order to achieve compatibility with the first type of downlink paging control information, and to implement the availability indication of the second type of paging downlink control information and/or the carrying of the configuration change of the preset reference signal. In this embodiment of the present disclosure, in response to the second type of paging downlink control information having the same message format as the first type of paging downlink control information, the availability indication is determined by the indication field that is not in the first type of paging downlink control information. The bit value occupied by the downlink control information of one type of paging is carried; or, the availability indication is carried by the bits in the message field that are not occupied by the downlink control information of the first type of paging.

Exemplarily, the indication field can be used to indicate the content carried in the message field. For details, refer to the following embodiments:

Table 1

The short message indication field in the table is the aforementioned indication field.

The table is a specific example of the indication field of the second type of paging DCI, and the specific implementation may not be limited to the above example. In Table 1, "00" is carried in the indication field to indicate that the availability of the preset reference signal changes or does not change. At this time, the indication field of the second type of paging DCI has 4 values, which are "00", "01", "10" and "11", wherein 01", "10" and "11" are the first The type of paging DCI is already occupied. Therefore, if the availability indication is indicated by the indication field, it can be carried by the unoccupied bit value "00" of the downlink control information of the first type of paging.

For example, if the bit value of the indication field of a paging DCI is: "00", it can be used to indicate availability status and/or availability change.

Reserved bits may be bits that are not occupied.

It is worth noting that one or more of the elements in Table 1 can be applied to paging DCI in combination or individually in paging DCI.

In one embodiment, of course, the availability indication of the preset reference signal may also be carried in the message field of the second type of paging DCI. For example, the availability indication may be carried by bits or bit values in the message field of the second-type paging DCI that are not occupied by the first-type paging DCI.

Exemplarily, the formats of the second type of paging DCI and the first type of paging DCI are the same, and the number of bits included in the message field is also the same. In the embodiment of the present disclosure, the second type of paging DCI may reserve some bits in the message field for carrying relevant information of the preset reference signal, where the relevant information includes: the aforementioned availability indication and/or configuration change.

Illustratively, the bit arrangement of the message field may be as follows:

	消息域(Message indicator)Message field (Message indicator)
0000	TRS/CSI-RS的可用性变更(availability change)Availability change of TRS/CSI-RS
0101	TRS/CSI-RS的配置变更(configuration change)Configuration change of TRS/CSI-RS
1010	保留(Reserved) Reserved
1111	保留(Reserved)Reserved

Table 2

Table 2 shows that two bits are taken from the message field of the second type of paging DCI to carry the availability change and the configuration change.

In one embodiment, availability changes and configuration changes, can use two different bit values occupying two bits.

In another embodiment, two bits are removed in the message field of the second type of paging DCI, wherein one bit is used to carry the availability change, and the other bit is used to carry the configuration change. In this way, the two bit values of one bit correspond to availability and unavailability in the availability state indicated by the availability, respectively, or correspond to change and no change of availability change. The two-bit value of one bit can correspond to two indications of configuration change change and no change.

The bits taken out from the message field of the second type of paging DCI and used to carry availability changes and/or configuration changes may be reserved bits relative to the first type of paging DCI, or may be bits that have been used by the first type of paging DCI. The paging DCI occupies bits used for scheduling messages carrying short messages and/or paging messages.

In one embodiment, the format of the second type of paging DCI and the first type of paging DCI is the same, the second type of paging DCI continues to use the format of the first type of paging DCI, and a carrying flag is introduced, which carries The mark is used to indicate that the second type of paging DCI at least carries the availability indication and/or configuration change of the preset reference signal.

Exemplarily, in response to the second type of paging downlink control information having the same message format as the first type of paging downlink control information, the indication field of the second type of paging downlink control information is indicating the availability. The scrambling sequence when the indication carries the flag is different, and the message field of the downlink control information of the second type of paging carries the availability indication.

In one embodiment, the carrying flag corresponds to a bit value in the indication field that is not occupied by the DCI of the first type of paging. If the indication field carries a carry flag, the message field of the second-type paging DCI carries at least one of the foregoing availability change and/or configuration change.

In another embodiment, in response to the indication field not carrying the carrying flag of the availability indication, the configuration change is caused by the second type of paging downlink control information that is not within the indication field of the first type Bit value indication occupied by paging downlink control information;

or,

In response to the indication field indicating the carrying flag of the availability indication, the configuration change is carried by the message field of the second type of paging downlink control information.

If the message formats of the second-type paging DCI and the first-type paging DCI are different, the second-type paging DCI is only the paging DCI that can be transmitted on the same resource as the first-type paging DCI, but the message format is the same as that of the first-type paging DCI. The contents are different. If the format of the second type of paging DCI and the first type of paging DCI are different, the availability indication and/or configuration change may be carried anywhere within the second type of paging DCI.

In some embodiments, the scrambling sequence of the second type of paging downlink control information is different from the scrambling sequence of the first type of paging downlink control information.

In some embodiments, the scrambling sequence of the second type of paging downlink control information carrying the configuration change alone may be different from the scrambling sequence of the second type of paging downlink control information carrying the availability indication alone sequence.

The scrambling sequence of any type of paging downlink control information here may be RNTI. Exemplarily, the scrambling sequences of the first type of paging downlink control information and the second type of paging downlink control information may be the same or different. For example, the scrambling sequence of the first type of paging downlink control information and the second type of paging downlink control information may be: Paging Radio Network Temporary Identity (P-RNTI).

The scrambling sequence of the second type of paging downlink control information is different from the first type of paging message control information, the scrambling sequence of the first type of paging downlink control information is P-RNTI, and the second type of paging downlink control information The RNTI of the control information may be TRS-RNTI.

In order to facilitate decoding by the UE, if the sequence used for descrambling the first type of paging downlink control information and the second type of paging downlink control information is different, it can be easily determined whether the currently received paging DCI carries an availability indication.

In an embodiment, when the message formats of the first type of paging downlink control information and the second type of paging downlink control information are the same, both types of paging downlink control information include: a message field. In the first type of paging downlink control information, the message field is originally intended to be used for carrying scheduling messages and/or short messages of paging messages. In the embodiment of the present disclosure, the message field of the second type of paging downlink control information may also be used to carry the availability indication of the preset reference signal and/or the configuration change of the preset reference signal.

Signal availability indication and/or configuration changes.

Similarly, if it is found in the communication protocol or based on the results of pre-negotiation that the availability indication is invalid or the network side has issued a configuration change for the preset reference signal, the UE needs to obtain a new availability indication. At this time, the UE can pass the system message Obtain or obtain the scheduling message or paging message change notification of the system.

The embodiments of the present disclosure provide a process for transmitting the availability indication of TRS/CSI-RS, which mainly relates to a process for a UE to obtain the availability indication for TRS/CSI-RS from a system message.

Only applicable to idle/inactive users;

The availability indication includes TRS/CSI-RS available (available) or unavailable (unavailable) information;

The availability also indicates TRS/CSI-RS availability changes, from available to unavailable or from unavailable to available;

The available state: that is, the configuration of the resource exists reasonably, and the network is actually sending the specific reference signal corresponding to the resource; at this time, it is available for the UE; the network expects the UE to use it;

Unavailable state: that is, the configuration of the resource does not exist reasonably, or the configuration of the resource exists reasonably but the network is not actually sending the specific reference signal corresponding to the resource; at this time, it is unavailable for the UE; The network does not expect the UE to use

In one embodiment, the network may send the availability indication for TRS/CSI-RS in the following ways:

Display method:

carried in the MIB;

carried in SIB-1;

It is carried in the reserved bits of the PDCCH DCI of the scheduling SIB-1;

It is carried in SIB-X, where SIB-X carries the configuration information of TRS/CSI-RS;

It is carried in the reserved bits of the PDCCH DCI for scheduling SIB-x;

carried in a new PDSCH (SIB) scrambled by SI-RNTI;

It can be understood that the TRS/CSI-RS availability indication may be one indication or multiple indication bits, wherein each indication bit is associated with the availability of one TRS/CSI-RS resource.

The availability indication of TRS/CSI-RS may be a bit or a bitmap. Each bit is associated with a TRS/CSI-RS resource availability indication. If the availability indication only needs to indicate whether it is available or unavailable, or indicates whether it is changed or not, that is, two expressions of on/off, it can be in the form of a bitmap. As an embodiment: the TRS/CSI-RS availability indication may be named as TRS/CSI-RS availability value tag.

It can be understood that the value tag is in the range of 0 to N.

As an example, N=1; that is, only by on/off flipping,

As an embodiment, N=31;, that is, the indication tag (value tag) of the system message in the related art is multiplexed.

It can be understood that the availability indication for TRS/CSI-RS is carried in the system message, and its change will not trigger the system message update procedure.

As an embodiment, the availability indication for TRS/CSI-RS is carried in the SIB-X, and its change will not trigger the system message update process.

As an embodiment, the availability indication for TRS/CSI-RS is carried in SIB-1, and its change will not trigger the system message update process.

The availability indication is carried in an implicit manner. Whether there is scheduling information carrying SIB-X in SIB-1 has a corresponding relationship with the availability indication of the preset reference signal; or, whether there is TRS/CSI-RS carried in SIB-x The configuration information has a corresponding relationship with the availability indication of the preset reference signal.

In one embodiment, the UE needs to obtain the availability indication for TRS/CSI-RS from the system message in at least one of the following situations:

Cell selection is performed after power-on; for example, the UE is powered off and then powered on again.

Enter a new cell after cell-reselection.

Return to the service area, that is, return from out of coverage to the coverage area. The coverage area is the service area; outside the coverage area is the non-service area.

The cell 1 is reselected from other radio access technologies (Radio Access Thechnolgy, RAT); for example, after entering the network from another RAT. Exemplarily, the UE is handed over from a 4G cell to a 5G cell.

High layer indication, (upon receiving request from upper layers), the high layer indication may include access stratum (AS) indication, non-access stratum (NAS) indication or RRC indication.

The previously obtained TRS/CSI-RS availability indication is invalid. For example, the validity period of the availability indication can be agreed according to the communication protocol or negotiation. If the valid period of an availability indication has reached the valid period, the availability indication is invalid.

For the scenario where the Paging DCI/PEI is used to send the TRS/CSI-RS availability indication, if the DRX cycle is longer than the TRS/CSI-RS update cycle, the UE misses the Paging DCI/PEI to send the TRS/CSI-RS availability indication; The availability indication of the TRS/CSI-RS is obtained before PO monitoring, and then PO monitoring is performed according to the availability indication.

In one embodiment, the UE also needs to obtain the availability indication for TRS/CSI-RS from the system message update procedure in the related art or the availability of TRS/CSI-RS sent by Paging DCI/PEI in the following cases.

When the availability of TRS/CSI-RS changes, the network will send the TRS/CSI-RS availability indication change from the system message update procedure in the related art or through Paging DCI/PEI. The system message update process of the related art is that the network only notifies the system message that there is a change, and the UE needs to obtain the change of the specific system message from the system message. For the availability of Paging DCI/PEI sending TRS/CSI-RS, see the following example:

Case 1: The TRS/CSI-RS availability indication can be directly carried in the Paging DCI/PEI, one embodiment is the bit/bit bitmap.

Case 2: The Paging DCI/PEI can directly carry a general indication that the TRS/CSI-RS availability indication has changed, and the specific TRS/CSI-RS availability indication needs to be obtained from the system message through 2).

As an embodiment, the reserved bits in the short message (short message) are used to carry the availability indication of the TRS/CSI-RS, such as the availability change flag of the TRS/CSI-RS. The sign of availability change here is one of the aforementioned availability changes.

As an example, bits are reserved in short messages for availability changes such as TRS/CSI-RS.

table 3

It is worth noting that one or more of the elements in Table 3 can be applied to paging DCI in combination or individually in paging DCI.

As an embodiment, a new RNTI scrambled paging DCI is introduced to indicate TRS/CSI-RS availability/configuration change; for example, TRS-RNTI can be invisible to legacy UEs, so it will not wake up old UEs UE. Exemplarily, the paging DCI carrying the availability indication may be scrambled with a cyclic redundancy check (Cyclic Redundancy Check, CRC) with TRS-RNTI. The format of the paging DCI may be format 1-0. The paging DCI may have N bits.

The short message indication here is equivalent to the aforementioned message field.

The paging DCI can have the following formats:

Format 1:

1 bit in the message indication field (Messages Indicator), used for availability indication, the value of this bit is "0" and "1", which can be respectively unavailable/available; the remaining N-1 bits are used for subsequent pre- reserved for use.

There are multiple reserved bits in the paging DCI, which can be used to indicate whether a set of configurations of preset reference signals are available.

Format 2:

Messages Indicator field (Messages Indicator) - Indicates with two bits: availability change and/or configuration change of the preset reference signal. The remaining N-2 bits are reserved for subsequent use.

Table 4

It is worth noting that one or more of the elements in Table 4 can be applied to paging DCI in combination or individually in paging DCI.

When the TRS/CSI-RS configuration changes, the network will send the TRS/CSI-RS configuration change through the relevant system message update process or Paging DCI/PEI;

For Paging DCI/PEI to send TRS/CSI-RS configuration change, as an embodiment, a new bit (bit) is added to the short message (short message), such as TRS/CSI-RS configuration change (configuration change flag) ;

As an embodiment, bits are reserved in a short message for configuration change (configuration change flag;) such as TRS/CSI-RS.

The bit values "00" and "01" of the bit field here correspond to the first bit value and the second bit value in the message field of the second type of paging downlink control information in the foregoing embodiment, respectively.

In one embodiment, the configuration of the paging DCI may also be as follows, that is, the paging DCI may carry a configuration change of the preset reference signal.

table 5

It is worth noting that one or more of the elements in Table 5 can be applied to paging DCI in combination or individually in paging DCI.

As an embodiment, a new RNTI scrambled paging DCI is introduced to indicate a TRS/CSI-RS configuration change; for example, TRS-RNTI.

In the case where the configuration of TRS/CSI-RS is changed, the UE still needs to obtain the availability indication of TRS/CSI-RS after obtaining the updated configuration, wherein the availability indication of TRS/CSI-RS needs to be obtained from the system message .

As an example: for the network side: after the updated configuration, the availability value tag (availability value tag) of the TRS/CSI-RS change in the system message or the scheduling message of the system message may start from the initial value "0". The initial value "0" identifies the unavailability of the preset reference signal.

As an example: for the network side: after the updated configuration, the availability value tag (availability value tag) of the TRS/CSI-RS availability change in the system message or the scheduling message of the system message may take the value +1 from before the change.

There are two ways for the network to provide the availability indication. One is to indicate through the bit tag (availability value tag) in the system message; the second is to send the availability indication through the system message update process (such as Paging DCI/PEI). In one embodiment, the UE supports receiving the availability indication through the bit tag of the system message and receiving the availability indication through the update procedure of the system message.
