[0040] like Figure 2 As shown, an embodiment of the present disclosure provides an information processing method, which is applied in a base station and includes:

[0041] S110: Sending an availability indication of a preset reference signal through a preset message; wherein the preset reference signal includes: TRS, and / or CSI-RS; the availability indication is used to indicate the availability of the preset reference signal.

[0042] In an embodiment of the present disclosure, the base station sends an availability information indication of a preset reference signal through a preset message. The availability indication can be used for the UE to determine the availability of the preset reference signal, and the availability includes: the preset reference signal is available and / or the preset reference signal is unavailable.

[0043] The preset reference signal at least includes: TRS and / or CSI-RS.

[0044] In one embodiment, the preset reference signal may be a reference signal that originally has a first function; in the embodiment of the present disclosure, the preset reference signal may also be used for a second function; the second function may be different from the first function.

[0045] Exemplarily, the TRS is originally intended to be used for UE phase tracking; and the CSI-RS can be used to acquire channel state information.

[0046] In an embodiment of the present disclosure, the original first function of the TRS as the preset reference signal may be: phase tracking; and the original first function of the CSI-RS as the preset reference signal may be used for the acquisition of channel state information. The second function of the TRS may include: adjustment of the automatic gain control (AGC) of the UE, radio resource management (RRM) of the UE, and / or time-frequency domain synchronization between the UE and the base station. Similarly, the second function of the CSI-RS may also include: increase of the AGC of the UE, RRM of the UE, and / or time-frequency domain synchronization between the UE and the base station. In an embodiment of the present disclosure, the time-frequency domain synchronization may include: time domain synchronization between the UE and the base station, and / or alignment of the UE and the base station in the frequency domain.

[0047] By sending the availability indication, the UE can be informed whether the configuration of the preset reference signal currently received is available. If available, the preset reference signal can be monitored at the transmission position of the preset reference signal according to the configuration of the received preset reference signal, and the corresponding function can be performed based on the monitored preset reference signal. If not available, the UE can enter a power saving state, for example, enter a longer sleep state, or be in a non-connected state for a longer time, thereby saving the power consumption of the UE.

[0048] The configuration of the preset reference signal may also be referred to as: configuration information of the preset reference signal or configuration parameters of the preset reference signal.

[0049] Exemplarily, the configuration of the preset reference signal may include at least one of the following:

[0050] Preset reference signal resource configuration;

[0051] A sequence configuration of a preset reference signal, for example, the sequence configuration of the preset reference signal, a sequence generation parameter of the preset reference signal, etc.;

[0052] A quasi colocation (QCL) configuration of a preset reference signal, the QCL configuration comprising at least a QCL parameter;

[0053] Configuration of the number of preset reference signals;

[0054] Preset reference signal period configuration;

[0055] Functional configuration of the preset reference signal; for example, the functional configuration indicates whether it is used for the second function, and / or which specific sub-function in the second function is used;

[0056] The effective configuration of the preset reference number, for example, the effective configuration of the preset reference signal, may be used to indicate the effective condition and / or effective timing of the configuration information for the preset reference signal;

[0057] The offset configuration between the preset reference signal and other reference signals may include: an offset configuration in the time domain and / or an offset configuration in the frequency domain.

[0058] Of course, the above is only an example of the configuration information of the preset reference signal. In specific implementation, the specific content of the configuration information is not limited to the above example.

[0059] In some embodiments, the S210 may include:

[0060] The availability indication of the preset reference signal for the non-connected UE is sent through a preset message.

[0061] The preset message may include various messages sent by the base station. In the embodiment of the present disclosure, the preset message is an availability indication of a preset reference signal sent to a UE in a non-connected state. Therefore, the preset message may be any message that can be received by any non-connected UE, or any message that the non-connected UE receives when it is in a connected state before entering the non-connected state.

[0062] In some embodiments, the availability indication includes:

[0063] The first type of indication is used to indicate the availability status of whether the preset reference signal is available;

[0064] and / or,

[0065] The second type of indication is used to indicate the availability change of the configuration of the preset reference signal.

[0066] The first type of indication is an indication of the availability status, and the availability indication directly indicates whether the configuration of the corresponding preset reference signal is available or unavailable. After receiving the first type of indication, the UE can 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.

[0067] In summary, the availability status includes: an available status indicating available, and / or an unavailable status indicating unavailable.

[0068] The second type of indication is an indication of a change in the availability status 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 preset reference signal corresponding to the second type of indication is currently available, and then combine the availability change to finally determine whether the configuration of the corresponding preset reference signal is available.

[0069] In summary, the availability change may include: an availability change indicating an availability change, and / or an availability change maintaining the current availability without change.

[0070] In some embodiments, the availability indication may be in a variety of formats, and at least two optional formats are provided below:

[0071] The availability indication includes: a bit map; wherein the bit map includes: one or more indication bits; wherein one bit in the indication bits is used to indicate the availability status of a set of configurations of the preset reference signal; or, one bit in the first type of indication bits is used to indicate an availability change of a set of configurations of the preset meal card signal.

[0072] In the form of a bit map, the availability of one or more configurations of the preset reference signal can be indicated with minimal bit overhead.

[0073] 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 indicating bit, respectively carrying the availability or unavailability of the corresponding preset reference signal configuration; or, the indicated bit values ​​"0" and "1" may be indicated by respectively carrying whether the availability of the configuration of the corresponding preset reference signal has changed. If the availability has changed, then after receiving the bitmap, the UE will change the availability state of the configuration of the corresponding set of preset reference signals to the opposite availability state of the configuration of the corresponding set of preset reference signals. If the availability has not changed, then after receiving the bitmap, the UE will maintain the current availability state of the configuration of the corresponding set of preset reference signals.

[0074] In one embodiment, the availability indication includes an indication tag (availability value tag); the indication tag or each of the plurality of indication tags is used to carry a set of configured availability indications of the preset reference signal.

[0075] The value of the indication tag may include: 0 and 1, or may include multiple values ​​such as 0-7, 0-15, or 0-31.

[0076] The value of the indication tag may be embodied by one or more indication bits, or may correspond to different values ​​by different amplitudes and / or different frequencies of the waveform of the modulated signal.

[0077] If an indication tag is used to carry the availability indication of the configuration of the preset reference signal, since the indication tag may include multiple values, it can be used to indicate that the configuration of the preset reference signal is available, and the remaining values ​​can be used to indicate that the configuration of the preset reference signal is unavailable. Alternatively, multiple values ​​in an indication tag can be used to indicate that the availability status of the configuration of the preset reference signal has changed, and the remaining values ​​can be used to indicate that the availability status of the configuration of the preset reference signal has not changed.

[0078] Exemplarily, one of the indication tags includes 32 values, which are 0 to 31. 1 or 31 of the 32 values ​​can be used to indicate that the availability status has changed, and the remaining values ​​can be used to indicate that the availability status has not changed.

[0079] 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 resource control (RRC) message sent by the base station.

[0080] Several optional ways of presetting the message are provided below, which may specifically include at least one of the following:

[0081] System information;

[0082] Scheduling information of system information;

[0083] Paging message change message.

[0084] System information can be divided into: broadcast system information blocks and on-demand system information blocks. System information carrying the availability indication may include: broadcast system information blocks. In this way, even if the UE misses the availability indication sent by the cell through the paging message change message, it can still receive the availability indication through the broadcast system information block. If the availability indication is carried in a request-based system information block, if the UE misses the availability indication sent by the base station in other ways (for example, through a paging message change notification) after entering the cell, it can request the base station for an on-demand system information block carrying the availability indication of the configuration of the preset reference signal through a system information block acquisition request.

[0085] The scheduling information of the system information may include DCI of various PDCCH transmissions.

[0086] In one embodiment, the system information may include:

[0087] Main message block MIB;

[0088] System information block SIB-Y; wherein Y is a positive integer.

[0089] The paging message change notification may be a notification message of scheduling or transmission change of any paging message.

[0090] If Y=1, SIB-Y is SIB-1, and both SIB-1 and MIB are system information blocks broadcast by the base station in the cell.

[0091] Exemplarily, the paging message change notification includes but is not limited to:

[0092] Paging Downlink Control Information (Paging DCI);

[0093] and / or,

[0094] Paging Early Indication (PEI).

[0095] In one embodiment, in response to the preset message being the scheduling information of the system information, the availability indication is carried by a reserved bit carried in the downlink control information that schedules the system information. Exemplarily, in response to the preset message being the scheduling information of the system information and the system information being SIB-Y, the availability indication is carried by a reserved bit carried in the downlink control information that schedules SIB-Y.

[0096] In one embodiment, the SIB-Y is:

[0097] SIB-1;

[0098] or,

[0099] SIB-X, wherein X is a positive integer greater than or equal to 2.

[0100] In one embodiment, the SIB-X may be SIB-2, SIB-3, SIB-4 or SIB-5, etc. Exemplarily, the SIB-X may include: a newly introduced SIB, a SIB dedicated to carrying the availability indication of the preset reference signal.

[0101] 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 is different from the scrambling sequence of SIB-Z1, where Z1 is a positive integer not equal to 1.

[0102] Exemplarily, the scrambling sequence of the SIB-X carrying the availability indication is different from the scrambling sequence of the SIB-X not carrying the availability indication; or, the scrambling sequences of the SIB-X carrying the availability indication are different from those of SIB-Z2; and Z2 is a positive integer that is not equal to X.

[0103] The SIB-X here is the SIB proposed in the related art to be multiplexed to carry the availability indication, and may also be a newly proposed SIB. In one embodiment, the SIB-X, wherein X is a positive integer greater than or equal to 2; the SIB-X is a SIB for scheduling the physical downlink shared channel PDSCH scrambled by the first system information SI-radio network temporary identifier RNTI, carrying the availability indication; the SIB-X for scheduling the PDSCH scrambled by the second SI-RNTI does not carry the availability indication. That is, the SIB-X, wherein 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 scrambled by the first system information SI-radio network temporary identifier RNTI; 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 and the first SI-RNTI.

[0104] In one embodiment, the SIB-X may be an existing SIB in the related art, and such 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 carries; the SIB-X of the scheduling information of the PDSCH scrambled by the second SI-RNTI does not carry the aforementioned availability indication.

[0105] In some cases, the second SI-RNTI may be the SI-RNTI that has been used to scramble SIB-X in the related art; and the first SI-RNTI is a newly proposed SI-RNTI that is different from the SI-RNTI.

[0106] Exemplarily, the first SI-RNTI and the second SI-RNTI are different. After the UE receives the corresponding SIB, if the descrambling is successful through the first SI-RNTI, it is considered that the currently received SIB-X carries the availability indication; if the descrambling is successful through the second SI-RNTI, it can be considered that the currently received SIB-X does not carry the availability indication.

[0107] In some other embodiments, the SIB-X is the SIB of the scheduled physical downlink shared channel PDSCH scrambled by the third SI-RNTI, carrying the availability indication; the SIB-Z of the scheduled PDSCH scrambled by the fourth SI-RNTI does not carry the availability indication; Z is a positive integer not equal to X.

[0108] For example, SIB-X may be a newly proposed SIB, which can be used to carry the availability indication. SIB-Z may include SIB-Z different from SIB-X mentioned in the related art. SIB-Z and SIB-X are scrambled with different SI-RNTIs.

[0109] Exemplarily, the fourth SI-RNTI is different from the third SI-RNTI.

[0110] In summary, SIB-X and SIB-Z other than SIB-X are scrambled with different SI-RNTIs, which facilitates the UE to quickly determine whether that SIB carries the availability indication according to the successfully scrambled sequence after receiving it.

[0111] The availability indication can be explicitly carried by indication bits or can be implicitly indicated.

[0112] For example, one or more indication bits are carried in SIB-Y, and these indication bits specifically carry the availability indication.

[0113] For another example, the availability indication is implicitly indicated by the correspondence between whether a certain piece of information in SIB-Y carries the availability indication.

[0114] Therefore, in some embodiments, SIB-1 implicitly indicates the availability indication by whether it contains the scheduling information of SIB-X;

[0115] SIB-X implicitly indicates the availability indication by whether it contains the configuration of the preset reference signal. If the configuration of the preset reference signal is placed in SIB-1, the availability indication can be implicitly indicated by whether SIB-1 contains the configuration of the preset reference signal.

[0116] After the UE receives SIB-Y that implicitly indicates the availability indication, it can determine the availability indication of the current configuration of the preset reference signal according to any of the above corresponding relationships.

[0117] In some embodiments, the SIB-X included in SIB-Y is further used to carry the configuration of the preset reference signal, where X is a positive integer greater than or equal to 2.

[0118] Different sets of preset reference signal configurations have different time-frequency resources for transmitting at least part of the preset reference signals.

[0119] For example, for the configuration of preset reference signals for different types of UEs, the time-frequency resources used are at least partially different, and thus can be considered as two sets of configurations of preset reference signals.

[0120] In some embodiments, when the availability indication carried by the system information or the scheduling information of the system information changes, the system information update process is not triggered. Exemplarily, when the availability indication carried by the SIB-Y changes, the system information update process is not triggered. Exemplarily, when the availability indication carried by the SIB-Y changes, the indication tag update of the SIB-Y is not triggered.

[0121] That is, when the UE receives a message carrying an availability indication change, it will not trigger the UE to initiate a system information update process, thereby initiating a message request for obtaining updated system information.

[0122] In summary, the system information may carry the availability indication explicitly through an indication bit; or, may carry the availability indication through an implicit indication.

[0123] The availability indication may be the aforementioned indication of the availability status and / or an indication of the availability change.

[0124] Exemplarily, when the availability indication carried by the system information or the scheduling information of the system information changes, the system information update procedure is not triggered. Exemplarily, when the indication tag of the availability indication carried by the SIB-Y changes, the system information update procedure is not triggered.

[0125] 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.

[0126] The paging message change notification may be physical layer signaling. The physical layer signaling has relatively few bits, and the availability change may be reduced as much as possible, so that the availability indication may be implemented with as few bits as possible.

[0127] In one embodiment, the paging message change notification carries a bit map; the bit map includes one or more bits; wherein one of the bits is used to indicate a change in availability of a set of configurations of the preset reference signal.

[0128] In one embodiment, the paging message change notification carries an availability indication of a change in the availability 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 carried by the system information or the scheduling information of the system information.

[0129] Here, the overall availability of the configurations of multiple sets of preset reference signals carried is changed through the paging message change notification; this is equivalent to informing the UE that the availability of at least one set of preset reference signal configurations has changed, and the availability of each set of preset reference signal configurations after the change can be carried by system information or system information scheduling information.

[0130] In some embodiments, the paging downlink control information may be any message transmitted on the resource for sending the paging DCI scheduled by the base station. Exemplarily, according to whether it carries an availability indication, the paging downlink control information may include two categories: the first category of paging downlink control information is paging DCI that does not carry an availability indication, and the second category of paging downlink control information is paging DCI that carries an availability indication.

[0131] 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 not carrying the availability indication.

[0132] The first type of paging downlink control information may be paging DCI provided in the related art, and the paging DCI carries at least one of scheduling information of a short message and / or a paging message sent to the UE.

[0133] The second type of paging downlink control information may carry one of the indications of the scheduling information of the short message and / or the paging message, or may not carry at least one of the scheduling information of the short message and / or the paging message, but may carry at least one of the availability indication and / or configuration change of the preset reference signal.

[0134] 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 use the message format used in the related art to carry scheduling information of short messages and / or paging messages, or may separately agree on a new message format.

[0135] In other embodiments, the second type of paging DCI may continue to use the message format of the first type of paging DCI, but the content carried by each bit in the message format may be redefined. In this case, the availability indication and / or configuration change of the preset reference signal carried by the second type of 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.

[0136] 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, after receiving the UE, the UE can distinguish whether the currently received paging DCI is the first type of paging DCI or the second type of paging DCI by using different sequences for descrambling.

[0137] In one embodiment, the second type of paging downlink control information may be a newly added type of paging downlink control information. Exemplarily, the second type of paging downlink control information may be used to exclusively carry the aforementioned availability indication.

[0138] In one embodiment, the second type of paging downlink control information includes: an indication field and a message field. In some cases, the indication field is generally used to indicate the content carried by the message field. At least one of the indication field and the message field includes one or more bits. Exemplarily, the number of bits included in the message field is greater than the number of bits included in the indication field.

[0139] In some cases, if the message format of the second-category paging downlink control information is the same as that of the first-category paging downlink control information, the number of bits included in the indication field of the second-category paging downlink control information is the same as the number of bits included in the first-category paging downlink control information; and the number of bits included in the message field of the second-category paging downlink control information is the same as the number of bits included in the first-category paging downlink control information.

[0140] In order to achieve compatibility with the first type of downlink paging control information and to carry the availability indication of the second type of downlink paging control information and / or the configuration change of the preset reference signal. In the embodiment of the present disclosure, in response to the second type of downlink paging control information having the same message format as the first type of downlink paging control information, the availability indication is carried by the bit value in the indication field that is not occupied by the first type of downlink paging control information; or, the availability indication is carried by the bit in the message field that is not occupied by the first type of downlink paging control information.

[0141] Exemplarily, the indication field may be used to indicate the content carried in the message field, and details may be referred to in the following embodiments:

[0142]

[0143] Table 1

[0144] The short message indication field in the table is the aforementioned indication field.

[0145] The table shows specific examples of the indication field of the second type of paging DCI, which may not be limited to the above examples when implemented specifically. The "00" carried in the indication field in Table 1 is used to indicate that the availability of the preset reference signal has changed or not changed. At this time, the indication field of the second type of paging DCI has 4 values, namely "00", "01", "10" and "11", among which 01", "10" and "11" are already occupied by the first type of paging DCI. Therefore, if the availability indication is indicated by the indication field, it can be carried by the bit value "00" not occupied by the first type of paging downlink control information.

[0146] For example, if the bit value of the indication field of a paging DCI is “00”, it can be used to indicate the availability status and / or availability change.

[0147] The reserved bits may be bits that are not occupied.

[0148] It should be noted that one or more elements in Table 1 may be combined and applied to paging DCI or applied to paging DCI individually.

[0149] 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 paging DCI. For example, the availability indication may be carried by a bit or a bit value in the message field of the second type paging DCI that is not occupied by the first type paging DCI.

[0150] Exemplarily, the second type of paging DCI and the first type of paging DCI have the same format, 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 can reserve some bits in the message field specifically for carrying relevant information of the preset reference signal, where the relevant information includes: the aforementioned availability indication and / or configuration change.

[0151] Exemplarily, the bit arrangement of the message field may be as follows:

[0152] Message indicator 00 TRS / CSI-RS availability change 01 TRS / CSI-RS configuration change 10 Reserved 11 Reserved

[0153] Table 2

[0154] Table 2 shows that two bits are taken out from the message field of the second type of paging DCI to carry the availability change and configuration change.

[0155] In one embodiment, availability change and configuration change may use two different bit values ​​occupying two bits.

[0156] In another embodiment, the two bit values ​​removed in the message field of the second type of paging DCI, 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 a bit correspond to the available and unavailable in the availability state of the availability indication, or to the change and no change of the availability change. The two bit values ​​of a bit can correspond to the change and no change of the configuration change.

[0157] The bits taken out from the message field of the second type of paging DCI for carrying availability changes and / or configuration changes may be reserved bits relative to the first type of paging DCI, or may be bits occupied by the first type of paging DCI for carrying scheduling information of short messages and / or paging messages.

[0158] In one embodiment, the format of the second type of paging DCI is the same as that of the first type of paging DCI. The second type of paging DCI continues to use the format of the first type of paging DCI, and introduces a carrying mark, which is used to indicate that the second type of paging DCI carries at least an availability indication and / or configuration change of a preset reference signal.

[0159] Exemplarily, in response to the fact that the message format of the second-category paging downlink control information is the same as that of the first-category paging downlink control information, the indication field of the second-category paging downlink control information has a different scrambling sequence when indicating the carrying mark of the availability indication, and the message field of the second-category paging downlink control information carries the availability indication.

[0160] In one embodiment, the carrying mark corresponds to the bit value in the indication field that is not occupied by the first type of paging DCI. If the indication field carries the carrying mark, the message field of the second type of paging DCI carries at least one of the aforementioned availability change and / or configuration change.

[0161] In another embodiment, in response to the indication field not carrying the carrying flag of the availability indication, the configuration change is indicated by a bit value in the indication field of the second type of paging downlink control information that is not occupied by the first type of paging downlink control information;

[0162] or,

[0163] In response to the indication field indicating a carrying flag of the availability indication, the configuration change is carried by the message field of the second-type paging downlink control information.

[0164] 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 a paging DCI that can be transmitted on the same resources as the first-type paging DCI, but the message format and the content carried are different. If the format of the second-type paging DCI and the first-type paging DCI are different, the availability indication and / or configuration change can be carried at any position in the second-type paging DCI.

[0165] 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.

[0166] In some embodiments, the scrambling sequence of the second type of paging downlink control information that solely carries the configuration change may be different from the scrambling sequence of the second type of paging downlink control information that solely carries the availability indication.

[0167] The scrambling sequence of any type of paging downlink control information here may be RNTI. For example, 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 sequences of the first type of paging downlink control information and the second type of paging downlink control information may be: paging radio network temporary identifier (P-RNTI).

[0168] The scrambling sequence of the second type of paging downlink control information is different from that of the first type of paging message control information. The scrambling sequence of the first type of paging downlink control information is P-RNTI, while the RNTI of the second type of paging downlink control information may be TRS-RNTI.

[0169] To facilitate UE decoding, different sequences are used for descrambling the first type of paging downlink control information and the second type of paging downlink control information, so it is easy to determine whether the currently received paging DCI carries an availability indication.

[0170] In an embodiment, the S110 may include: in response to a configuration change of the preset reference signal, sending an availability indication of the preset reference signal through the preset message.

[0171] like Figure 3 As shown, the embodiment of the present disclosure provides an information processing method, which is applied to a user equipment UE, including:

[0172] S210: Receive a preset message, wherein the preset message includes: an availability indication of a preset reference signal; wherein the preset reference signal includes: a TRS and / or a CSI-RS;

[0173] The availability indication is used to indicate the availability of the preset reference signal.

[0174] The UE may be a connected UE, an idle UE, or an inactive UE.

[0175] After receiving the availability indication, the UE can know the availability indication of the TRS and / or CSI-RS.

[0176] In one embodiment, the S210 may include: receiving the preset message for the non-connected UE. The non-connected state here includes: an idle state and / or an inactive state.

[0177] In one embodiment, the availability indication includes: a first type indication for indicating an availability status of whether the preset reference signal is available; and / or a second type indication for indicating an availability change of a configuration of the preset reference signal.

[0178] In one embodiment, the availability indication includes one or more indication tags; one of the indication tags or each of the multiple indication tags is used to carry a set of configured availability indications of the preset reference signal; the indication tag includes: N bits; wherein N is a positive integer equal to or greater than 2.

[0179] In one embodiment, the preset message includes: system information; and / or, scheduling information of the system information; and / or,

[0180] Paging message change notification.

[0181] Exemplarily, the paging message change notification includes: paging downlink control information paging DCI;

[0182] and / or, paging advance indication PEI.

[0183] In one embodiment, the system information includes at least one of the following: a master message block MIB; a system information block SIB-Y; wherein Y is a positive integer.

[0184] In one embodiment, in response to the preset message being scheduling information of the system information, the availability indication is carried by a reserved bit carried in the downlink control information that schedules the system information.

[0185] Exemplarily, in response to the preset message being scheduling information of the system information and the system information being SIB-Y, the availability indication is carried by a reserved bit carried in the downlink control information including the SIB-Y.

[0186] In one embodiment, the SIB-Y is: SIB-1, wherein the scrambling sequence of the SIB-1 carrying the availability indication is different from the scrambling sequence of the SIB not carrying the availability indication; or the scrambling sequence of the SIB-1 carrying the availability indication is different from the scrambling sequence of SIB-Z1, and Z1 is a positive integer not equal to 1;

[0187] or,

[0188] SIB-X, wherein X is a positive integer greater than or equal to 2; the scrambling sequence of the SIB-X carrying the availability indication is different from the scrambling sequence of the SIB-X not carrying the availability indication; or, the scrambling sequence of the SIB-X carrying the availability indication is different from the scrambling sequence of SIB-Z2; and Z2 is a positive integer SIB-1 that is not equal to X.

[0189] In one embodiment, the SIB-1 indicates the availability indication by whether it includes the scheduling information of the SIB-X; or, the SIB-X indicates the availability indication by whether it includes the configuration information of the preset reference signal; or, the SIB-X indicates the availability indication by whether it includes the configuration of the preset reference signal.

[0190] Exemplarily, the SIB-1 implicitly indicates the availability indication by whether it contains the scheduling information of the SIB-X; or, the SIB-X implicitly indicates the availability indication by whether it contains the configuration information of the preset reference signal; or, the SIB-X implicitly indicates the availability indication by whether it contains the configuration of the preset reference signal.

[0191] In one embodiment, the SIB-Y is further used to carry the configuration of the preset reference signal. Exemplarily, the SIB-X is further used to carry the configuration of the preset reference signal, wherein X is a positive integer greater than or equal to 2.

[0192] In one embodiment, when the availability indication carried by the system information or the scheduling information of the system information changes, the system information update procedure is not triggered. Exemplarily, when the availability indication carried by the SIB-Y changes, the system information update procedure is not triggered.

[0193] 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.

[0194] In one embodiment, the paging message change notification carries one or more indication tags; wherein one indication tag is used to indicate the availability change of a set of configurations of the preset reference signal.

[0195] In one embodiment, the paging message change notification carries the availability indication of the change in availability 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 carried by the system information or the scheduling information of the system information.

[0196] In one embodiment, the paging downlink control information includes: the paging downlink control information carrying the availability indication is second-type paging downlink control information, wherein the second-type paging downlink control information is different from the first-type paging downlink control information not carrying the availability indication.

[0197] In one embodiment, the message formats of the first type of paging downlink control information and the second type of paging downlink control information are the same. For example, both types of paging downlink control information include: an indication field; wherein, the reserved bit value of the indication field not occupied by the first type of paging downlink control information is used to carry the availability indication of the preset reference signal or the configuration change of the preset reference signal.

[0198] In view of this, in some embodiments, in response to the message format of the second type of paging downlink control information being the same as that of the first type of paging downlink control information, the availability indication is carried by the bit value in the indication field that is not occupied by the first type of paging downlink control information; or, the availability indication is carried by the bit in the message field that is not occupied by the first type of paging downlink control information.

[0199] In one 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 used to carry scheduling information of paging messages and / or short messages. In the embodiment of the present disclosure, the message field of the second type of paging downlink control information can also be used to carry an availability indication of a preset reference signal and / or a configuration change of a preset reference signal.

[0200] In one embodiment, in response to the fact that the message format of the second type of paging downlink control information is the same as that of the first type of paging downlink control information, the indication field of the second type of paging downlink control information has a different scrambling sequence when indicating the carrying mark of the availability indication, and the message field of the second type of paging downlink control information carries the availability indication.

[0201] 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 second type of paging downlink control information is further used to indicate a configuration change of the preset reference signal. The configuration change here can be carried by any bit or bit value not occupied by the first type of paging downlink control information.

[0202] Exemplarily, in response to the indication field not carrying the carrying mark of the availability indication, the configuration change is indicated by the bit value in the indication field of the second type of paging downlink control information that is not occupied by the first type of paging downlink control information; or, in response to the indication field indicating the carrying mark of the availability indication, the configuration change is carried by the message field of the second type of paging downlink control information.

[0203] In one embodiment, the S210 may include:

[0204] In response to a configuration change of a preset reference signal, the preset message carrying the availability indication is received.

[0205] The preset message may be a message sent by various network sides, such as physical layer signaling, MAC CE and / or RRC signaling, etc. After receiving the updated configuration change, by obtaining the availability indication, it can be known that the changed configuration is suitable to take effect, ensuring that the UE monitors preset reference signals such as TRS / CSI-RS according to the effective configuration.

[0206] In one embodiment, 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 one embodiment, the receiving of the preset message includes at least one of the following:

[0207] In response to performing cell selection, receiving system information or scheduling information of system information carrying the availability indication;

[0208] In response to performing cell reselection, receiving system information or scheduling information of system information carrying the availability indication;

[0209] In response to returning to the service area, receiving system information or scheduling information of system information carrying the availability indication;

[0210] In response to receiving the high-level indication, receiving system information or scheduling information of system information carrying the availability indication;

[0211] In response to the failure of the availability indication of the preset reference signal, receiving system information or scheduling information of the system information carrying the availability indication;

[0212] In response to the UE missing the paging downlink control information or PEI carrying the availability indication of the preset reference signal, receiving the system information or scheduling information of the system information carrying the availability indication.

[0213] When performing cell selection, cell reselection or returning to service, the UE may miss the relevant information of the preset reference signal sent by the base station based on the paging message change notification. The relevant information at this time includes but is not limited to: the availability indication and / or configuration change of the aforementioned preset reference signal. At this time, the UE can obtain the availability indication and / or configuration change based on the reception of system information.

[0214] The high-level indications here may include: non-access stratum (NAS) indications and / or access stratum (AS) indications or RRC indications from the network side, and it is necessary to receive the availability indication and / or configuration change of the preset reference signal by receiving system information or scheduling information of system information.

[0215] Similarly, when the communication protocol or based on the results of pre-negotiation finds that the availability indication is invalid or that 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 obtain it through system information or the system scheduling information of the message or paging message change notification.

[0216] The embodiments of the present disclosure provide a process for transmitting an availability indication of a TRS / CSI-RS, which mainly involves a process for a UE to obtain an availability indication for a TRS / CSI-RS from system information.

[0217] Only applicable to idle / inactive users;

[0218] The availability indication includes TRS / CSI-RS available (available) or unavailable (unavailable) information;

[0219] The availability indication also includes a change in TRS / CSI-RS availability, from available to unavailable or from unavailable to available;

[0220] The available state means that the configuration of the resource is reasonable and the network is actually sending the specific reference signal corresponding to the resource. At this time, it is available to the UE and the network expects the UE to use it.

[0221] The unavailable state means that the resource configuration is unreasonable, or the resource configuration is reasonable but the network does not actually send 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 the reference signal or the resources of the reference signal.

[0222] In one embodiment, the network may send the TRS / CSI-RS availability indication in the following ways:

[0223] Display mode:

[0224] Carried in the MIB;

[0225] Carried in SIB-1;

[0226] Carried in the reserved bits of the PDCCH DCI that schedules SIB-1;

[0227] Carried in SIB-X, where SIB-X carries the configuration information of TRS / CSI-RS;

[0228] Carried in the reserved bits of the PDCCH DCI that schedules SIB-x;

[0229] Carried in a new SI-RNTI scrambled scheduled PDSCH (SIB);

[0230] 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 a TRS / CSI-RS resource.

[0231] The availability indication of TRS / CSI-RS can be a bit or a bitmap. Each bit is associated with an availability indication of a TRS / CSI-RS resource. If the availability indication only needs to indicate available or unavailable or change or no change, that is, on / off, it can be expressed in the form of a bitmap. As an embodiment: the availability indication of TRS / CSI-RS can be named TRS / CSI-RS availability value tag.

[0232] It can be understood that the value tag has a value range of 0-N.

[0233] As an embodiment, N=1; that is, only by on / off switching,

[0234] As an embodiment, N=31; that is, the value tag of the system information in the related art is reused.

[0235] It can be understood that the TRS / CSI-RS availability indication is carried in the system information, and its change will not trigger the system information update process.

[0236] As an embodiment, the availability indication of TRS / CSI-RS is carried in SIB-X, and its change will not trigger the system information update process.

[0237] As an embodiment, the availability indication of TRS / CSI-RS is carried in SIB-1, and its change will not trigger the system information update process.

[0238] The availability indication is carried in an implicit manner. Whether there is scheduling information of SIB-X carried in SIB-1 corresponds to the availability indication of the preset reference signal; or whether there is configuration information of TRS / CSI-RS carried in SIB-x corresponds to the availability indication of the preset reference signal.

[0239] In one embodiment, the UE needs to obtain the availability indication for the TRS / CSI-RS from the system information in at least one of the following situations:

[0240] Cell selection is performed after powering on; for example, the UE is powered off and then powered on again.

[0241] Enter a new cell after cell reselection.

[0242] Returning to the service area means returning from out of coverage to the coverage area. The coverage area is the service area; the area outside the coverage is the non-service area.

[0243] Reselecting to enter the cell from another radio access technology (Radio Access Technology, RAT); for example, switching from a different system to a cell of the present system (after entering the network from another RAT). Exemplarily, the UE switches from a 4G cell to a 5G cell.

[0244] A high-layer indication (upon receiving request from upper layers), where the high-layer indication may include an access stratum (AS) indication, a non-access stratum (NAS) indication or an RRC indication.

[0245] The previously acquired TRS / CSI-RS availability indication is invalid. For example, the validity period of the availability indication may be agreed upon according to the communication protocol or negotiation. If the validity period of an availability indication has reached the validity period, the availability indication is invalid.

[0246] For the scenario where Paging DCI / PEI is used to send TRS / CSI-RS availability indication, if the UE's DRX cycle is greater than the TRS / CSI-RS update cycle, the UE will miss the TRS / CSI-RS availability indication sent by Paging DCI / PEI. The availability indication of the TRS / CSI-RS is obtained before PO monitoring, and then PO monitoring is performed based on the availability indication.

[0247] In one embodiment, the UE also needs to obtain the TRS / CSI-RS availability indication from the system information update process in the related technology or the Paging DCI / PEI sending TRS / CSI-RS availability under the following circumstances.

[0248] When the availability of TRS / CSI-RS changes, the network will send a TRS / CSI-RS availability indication change from the system information update process in the related technology or through Paging DCI / PEI. The system information update process in the related technology means that the network only notifies the system information of the change. As for the specific system information change, the UE needs to obtain it from the system information. For Paging DCI / PEI to send TRS / CSI-RS availability, see the following example:

[0249] Case 1: The TRS / CSI-RS availability indication may be directly carried in the Paging DCI / PEI, an embodiment of which is a bit / bit map.

[0250] Case 2: Paging DCI / PEI can directly carry a general indication of the change of TRS / CSI-RS availability indication, while the specific TRS / CSI-RS availability indication needs to be obtained from the system information through 2).

[0251] As an embodiment, reserved bits in a short message are used to carry TRS / CSI-RS availability indication, such as TRS / CSI-RS availability change flag. The availability change flag here is a type of the aforementioned availability change.

[0252] As an embodiment, bits are reserved in a short message for use in, for example, TRS / CSI-RS availability change.

[0253] Table 3

[0254] It should be noted that one or more elements in Table 3 may be combined and applied to paging DCI or applied to paging DCI individually.

[0255] As an embodiment, a new RNTI-scrambled paging DCI is introduced to indicate TRS / CSI-RS availability / configuration changes; for example, TRS-RNTI may be invisible to legacy UEs, so legacy UEs will not be woken up. Exemplarily, the paging DCI carrying the availability indication may be scrambled with a cyclic redundancy check (CRC) using TRS-RNTI. The format of the paging DCI may be format 1-0. The paging DCI may have N bits.

[0256] The short message indication here is equivalent to the aforementioned message field.

[0257] The paging DCI can have the following formats:

[0258] Format 1:

[0259] One bit in the message indicator field is used for availability indication. The value of this bit is "0" and "1", which can be unavailable / available respectively; the remaining N-1 bits are reserved for subsequent use.

[0260] Multiple reserved bits in the paging DCI may be used to indicate whether a set of configurations of a preset reference signal is available.

[0261] Format 2:

[0262] Message Indicator: Two bits are used to indicate: availability change and / or configuration change of the preset reference signal. The remaining N-2 bits are reserved for subsequent use.

[0263]

[0264] Table 4

[0265] It is worth noting that one or more elements in Table 4 can be combined and applied to paging DCI or applied alone to paging DCI.

[0266] The network will send TRS / CSI-RS configuration changes through the relevant system information update process or Paging DCI / PEI in case of TRS / CSI-RS configuration changes;

[0267] For sending TRS / CSI-RS configuration change via Paging DCI / PEI, as an embodiment, a new bit is added to the short message, such as TRS / CSI-RS configuration change flag;

[0268] As an embodiment, a bit is reserved in a short message for use as a configuration change flag of, for example, TRS / CSI-RS.

[0269] 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 aforementioned embodiment, respectively.

[0270] 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 a preset reference signal.

[0271]

[0272] Table 5

[0273] It should be noted that one or more elements in Table 5 may be combined and applied to the paging DCI or applied to the paging DCI individually.

[0274] As an embodiment, a new RNTI-scrambled paging DCI is introduced to indicate a TRS / CSI-RS configuration change; for example, TRS-RNTI.

[0275] When the TRS / CSI-RS configuration of the UE is changed, the UE still needs to obtain the TRS / CSI-RS availability indication after obtaining the updated configuration, wherein the TRS / CSI-RS availability indication needs to be obtained from the system information.

[0276] As an embodiment: for the network side: after the updated configuration, the availability value tag indicating the change of TRS / CSI-RS availability in the system information or the scheduling information of the system information may start from the initial value "0". The initial value "0" indicates the unavailability of the preset reference signal.

[0277] As an embodiment: for the network side: after the updated configuration, the bit tag (availability value tag) of the TRS / CSI-RS availability change in the system information or the scheduling information of the system information can take the value +1 from before the change.

[0278] The network provides availability indication in two ways. One is to indicate through the bit tag (availability value tag) in the system information; the second is to send the availability indication through the system information update process (such as Paging DCI / PEI). In one embodiment, the UE supports receiving the availability indication through the bit tag of the system information and receiving the availability indication through the system information update process.

[0279] As Figure 4 shown, an information processing device, which is applied to a base station and includes:

[0280] A sending module 410, configured to send the availability indication of a preset reference signal through a preset message; wherein, the preset reference signal includes: a tracking reference signal TRS, and / or, a channel state information-reference signal CSI-RS;

[0281] The availability indication is used to indicate the availability of the preset reference signal.

[0282] In some embodiments, the sending module 410 may be a program module; after being executed by a processor, the program module can send the availability indication of the preset reference signal through a preset message.

[0283] In some other embodiments, the sending module 410 may be a software-hardware combination module; the software-hardware combination module includes various programmable arrays; the programmable arrays include but are not limited to: a complex programmable array or a field programmable array.

[0284] In some embodiments, the sending module 410 is configured to send the availability indication of the preset reference signal for a non-connected state UE through a preset message.

[0285] In some embodiments, the availability indication includes:

[0286] A first type of indication, used to indicate the availability status of whether the preset reference signal is available;

[0287] A second type of indication, used to indicate the availability change of the configuration of the preset reference signal.

[0288] In some embodiments, the availability indication includes one or more indication tags; each of the one indication tag or the multiple indication tags is used to carry the availability indication of a set of configurations of the preset reference signal; the indication tag contains: N bits; wherein, the N is a positive integer equal to or greater than 2.

[0289] In some embodiments, the preset message includes: system information; and / or, scheduling information of the system information; and / or, a paging message change notification.

[0290] In some embodiments, the paging message change notification includes: paging downlink control information paging DCI; and / or paging advance indication PEI.

[0291] In some embodiments, the system information includes at least one of the following:

[0292] Main message block MIB;

[0293] System information block SIB-Y; wherein Y is a positive integer.
