[0004] In mobile communication networks, base stations typically continuously and periodically transmit reference signals, enabling user equipment (UEs) to perform measurements or synchronization based on these reference signals to meet UE requirements.

During the implementation of the present invention, the inventors discovered that while on-demand transmission of reference signals is one method for achieving network energy conservation, the prior art does not provide a technical solution for enabling UEs to receive and subsequently process these on-demand reference signals.

[0041] Embodiments of the present application provide a solution to the technical problem that, in existing technologies, reference signals can be sent on demand for network energy conservation, but there is no corresponding solution to enable user equipment to receive and subsequently process the reference signals. The present invention provides a technical solution in which, when a network-side device transmits a reference signal in an on-demand manner, the reference signal may be, for example, a synchronization signal block (SSB). The solution enables a user equipment to receive the on-demand reference signal based on the first information and perform at least one of measurement, synchronization, and automatic gain control adjustment. This solution enables the user equipment to successfully receive and subsequently process the reference signal even when the on-demand transmission of the reference signal is used for network energy conservation in a mobile communication system.

[0042] The technical solution of the reference signal processing method provided in the embodiments of the present application is described in detail below through some embodiments and application scenarios in conjunction with the accompanying drawings.

[0043] FIG2 is a flow chart of a reference signal processing method according to an embodiment of the present application. This step may be performed by a reference signal processing method, which may be set in a user equipment. As shown in FIG2 , the method includes the following steps:

[0044] Step 201: Receive first information sent by a network-side device, where the first information includes at least one of first measurement configuration information, an activation indication of the first measurement configuration information, and a reference signal transmission pattern;

[0045] The technical solution provided in the embodiments of the present application is a technical solution for transmitting reference signals on demand in order to achieve network energy saving in a mobile communication network. If the reference signal is an SSB, the on-demand transmission of the reference signal can be expressed as On-demand SSB. The characteristics of the transmission mode of this type of reference signal can be changing from not transmitting this type of reference signal to transmitting this type of reference signal, from transmitting the reference signal according to one period to transmitting the reference signal according to another period, or a method of transmitting an additional reference signal. Therefore, the network-side device needs to send a corresponding instruction to the user equipment to inform the user equipment how to receive the above-mentioned reference signal.

[0046] In this embodiment of the present application, a network device may send first information to a user equipment to instruct the user equipment on how to receive a reference signal sent on demand. The network device may be a base station of a primary cell serving the user equipment or a base station of an activated secondary cell.

[0047] Specifically, for a network-side device, the above-mentioned indication can be sent in three ways, and the first information can include at least one of three different types of indication information. The first type of indication information can refer to the measurement configuration information sent to the user equipment in the prior art and can be implemented compatible with the prior art. For example, the first information includes first measurement configuration information. The first measurement configuration information can be implemented by modifying the existing measurement configuration information. Sending the first measurement configuration information can also be considered as a new measurement configuration or reconfiguration. The second type of indication information indicates that although the network-side device has sent the above-mentioned first measurement configuration information to the user equipment, the first measurement configuration information will not take effect immediately. Instead, all or part of the above-mentioned first measurement configuration information needs to be activated by sending an activation indication of the first measurement configuration information. The activation indication can also be an explicit activation indication, an implicit activation indication, or a combination of an implicit activation indication and an explicit activation indication. The third type of indication information directly indicates the on-demand transmission of reference signal transmission-related information, such as the reference signal transmission pattern, so that the user equipment can directly understand the reference signal transmission pattern and receive the reference signal on the corresponding time-frequency resource.

[0048] Step 202: Receive a reference signal sent on demand based on the first information to perform at least one of measurement, synchronization, and automatic gain control adjustment;

[0049] If the above steps record that the first information can include at least one of the three types of indication information, it can accurately indicate how the user equipment can receive at least part of the reference signal sent on demand. Therefore, the user equipment can receive the reference signal sent according to the instruction in the above first information.

[0050] After receiving the above-mentioned on-demand reference signal, which may be a reference signal sent from a surrounding cell where the user equipment is located, such as a primary cell or a secondary cell, the user equipment may perform at least one of measurement, synchronization, and automatic gain control based on the above-mentioned reference signal. In an embodiment of the present application, the measurement refers to the measurement of the downlink signal of each cell, which may include at least one of an L1 measurement and an L3 measurement, and the final measurement value includes but is not limited to at least one of the reference signal received power, the reference signal received quality, and the signal interference plus noise ratio; the synchronization refers to the user equipment performing synchronization processing based on the reference signal to synchronize with the time of the base station; the automatic gain control refers to the user equipment being able to dynamically adjust the gain of the received signal based on the reference signal to adapt to changes in signal strength, thereby maintaining the stability and consistency of the user equipment output signal.

[0051] In the above embodiments of the present application, in order to achieve network energy saving on the network side device, the reference signal is sent in an on-demand manner, thereby reducing energy consumption and meeting the demand for network energy saving. The first information sent to the user equipment includes at least one of the first measurement configuration information, the activation indication of the first measurement configuration information, or the transmission pattern of the reference signal to notify the user equipment, so that the user equipment can successfully receive at least part of the reference signal according to the above first information and perform at least one of measurement, synchronization, and automatic gain control. Therefore, when the reference signal is sent in an on-demand manner for network energy saving, the reference signal can also be successfully received on the user equipment and subsequent processing can be performed, providing an effective solution.

[0052] The following embodiments will respectively introduce and illustrate in detail the three types of indication information included in the first information. Specifically, the first measurement configuration information may include at least one of the following:

[0053] The number of synchronization signal block measurement time indication SMTC;

[0054] Minimum number of SMTC measurements;

[0055] a transmission pattern of a reference signal;

[0056] A measurement object, used to indicate measurement of a reference signal sent on demand;

[0057] a first measurement window, the first measurement window being determined by at least one of a start position, an end position, and a measurement window length;

[0058] The first indication information is used to indicate a measurement object identifier or a measurement identifier in the second measurement configuration information received by the user equipment.

[0059] The synchronization signal block measurement time indication (SSB Measurement Timing Configuration, abbreviated as: SMTC) is a measurement window for the periodic and continuously sent SSB signal (always SSB), which is defined in the existing protocol. The SMTC has set parameters such as measurement period and measurement window length. In the existing technology, when measuring reference signals such as SSB, the measurement is performed according to the STMC configured in the measurement object. However, the technical solution for sending reference signals on demand used in the present application may not send reference signals continuously as in the existing technology, but only needs to send reference signals on demand within a period of time. The embodiment of the present application can indicate that the reference signals sent on demand are sent in these SMTCs at most by limiting the number of SMTCs, or by limiting the minimum number of SMTC measurements to indicate to the user equipment that the user equipment is expected to detect the reference signals sent on demand in the minimum number of SMTCs. By using SMTC in the embodiment of the present application, it is possible to match with the existing protocol and receive a reference signal that is not continuous but sent on demand in a short period of time.

[0060] For the measurement period, measurement window length and other parameters of SMTC in the above embodiment, one possible method is to configure them in a measurement object (Measurement Object). The measurement object can generally define the frequency for receiving the reference signal, which can also be called a time-frequency resource. Therefore, in an embodiment of the present application, a new measurement object can be defined. The measurement object reconfigures the measurement window according to the time-frequency resource where the reference signal sent on demand is located, so that the frequency measured by the measurement object can be consistent with the time-frequency resource where the reference signal sent on demand is located, thereby smoothly realizing the reception of the reference signal sent on demand on the user equipment.

[0061] In another implementation, a new first measurement window can be defined in the first measurement configuration information, and the user equipment only receives the reference signal within the first measurement window. At this time, if the network-side device still sends the reference signal according to the SMTC specified in the traditional protocol, the user equipment can receive the reference signal on the SMTC within the first measurement window, where the first measurement window can be determined by at least one of the starting position, the ending position, and the measurement window length. The receiving parameter information defined by the first measurement window can be determined by at least one of the starting position, the ending position, and the measurement window length, where the starting position can identify the position at which the reference signal measurement can be started, the ending position can identify the position at which the reference signal measurement can be ended, and the length of the measurement window can identify the duration of the measurement window in terms of timing.

[0062] In some embodiments, if only the starting position is included, the reference signal reception can be stopped in accordance with the preconfigured measurement duration, or the reference signal reception can be stopped at the preconfigured measurement end time; if only the end position is included, the reference signal reception can be started in accordance with the preconfigured measurement duration, or the reference signal reception can be started at the preconfigured measurement start time; if the end position or the end position is included and the window length is measured at the same time, the specific position of the entire first measurement window can be defined; if only the measurement window length is included, the reference signal reception can be started in accordance with the preconfigured measurement start time and the window length can be continuously measured.

[0063] In some embodiments, the on-demand reference signal sent by the network side device can be sent in a one-shot manner, that is, the reference signal is sent only once, and there is specific sending parameter information, such as at least one of the specific sending position, end position and sending duration, etc. The receiving parameter information limited by the first measurement window can be corresponding to the above-mentioned sending parameter information, so as to facilitate the reception of as many reference signals as possible sent in one shot by the network side device.

[0064] Regarding the above-mentioned first indication information, it can be understood that, in some embodiments, in addition to the reference signal sent on demand, the network side device also sends a periodic and continuous reference signal. Therefore, in the past time period or the current synchronization time period, some measurement configuration information has been sent. The measurement configuration information can be called second measurement configuration information. According to the provisions of the existing protocol for the network side device to send the second measurement configuration information, the second measurement configuration information can further include a measurement identifier (measId), and the measurement identifier is associated with a measurement object identifier (measObjectId) and one or more reporting configuration identifiers (reportConfigId).

[0065] As mentioned above, the measurement object specifies the specific frequency point to be measured, that is, the time-frequency resource, while the reporting configuration specifies the reporting criteria for how the measurement results are reported. The measurement identifier can be used to associate the above two, thus forming a complete measurement process.

[0066] In the above-mentioned second measurement configuration information, one or more measurement identifiers or measurement object identifiers may be configured. In an embodiment of the present application, when the first measurement configuration information includes first indication information, the first indication information may be used to indicate the measurement object identifier or measurement identifier in the second measurement configuration information received by the user equipment. In this way, the user equipment may be instructed by the first indication information to receive the reference signal according to the measurement object identifier or measurement identifier in the second measurement configuration information, and the content specified in the measurement object identifier or measurement identifier may continue to be used in whole or in part during the reception process. In this way, a specific measurement scheme may no longer be repeatedly specified, workload may be reduced, and the content length in the first measurement configuration information may be reduced, thereby improving communication efficiency and reducing bandwidth usage.

[0067] In the above embodiment, the first indication information may include only the above-mentioned measurement identifier or measurement object identifier, so that the user equipment can directly use the content specified in the second configuration information to complete the reception and subsequent processing of the reference signal sent on demand. In some cases, some new content may be additionally specified in the first indication information. When the additional new content overlaps or conflicts with the content in the second measurement configuration information, the content in the second configuration information may be replaced. However, for content not specified in the first indication information, the provisions of the second indication information continue to be used, such as the relevant content of the reporting configuration identifier associated with the measurement identifier.

[0068] In this case, specifically, the first indication information further includes at least one of the following:

[0069] a transmission pattern of a reference signal;

[0070] A second measurement window, and parameter information of the second measurement window.

[0071] The reference signal transmission pattern will be described in detail in subsequent embodiments.

[0072] The second measurement window can also be understood as a measurement window newly defined based on the transmission parameters of the reference signal. Therefore, its specific parameter information is further specified. The parameter information of the second measurement window may include at least one of the following:

[0073] The number of second measurement windows;

[0074] a measurement window length of the second measurement window;

[0075] The starting position of the second measurement window;

[0076] The end position of the second measurement window;

[0077] a measurement period of a second measurement window;

[0078] The position of the second measurement window within each measurement cycle.

[0079] In the embodiment of the present application, the specific number, starting position, measurement window length, end position, measurement period, and at least one of the positions within each measurement period of the second measurement window can be defined based on the time-frequency resources used by the reference signal sent on demand. The starting position, end position, and measurement window length of the second measurement window can refer to the introduction of the starting position, end position, and measurement window length of the first measurement device in the above embodiment. When at least one of the parameters is obtained, the specific time-frequency resource corresponding to the second measurement window can be defined based on the parameter or in combination with other pre-configured parameters. For the number and measurement period of the second measurement window, the repeatability of the corresponding specific time-frequency resource is defined. If the second measurement window is offset within each measurement period, that is, it does not start from the starting position of a measurement period, the offset of the second measurement window relative to the starting position of the measurement period can be defined by the position of the second measurement window in each measurement period.

[0080] In the above embodiments of the present application, the reference signal transmission pattern may be directly included in the first information, the reference signal transmission pattern may be directly included in the first measurement configuration information, or the reference signal transmission pattern may be directly included in the first indication information. The reference signal transmission pattern in each of the above embodiments may be defined using the same parameters, the difference being the different transmission methods. In this embodiment, the reference signal transmission pattern is set in the first measurement configuration information, and may be used not immediately but after being activated by the activation indication of the first measurement configuration information.

[0081] In the embodiment of the present application, the reference signal transmission pattern may include at least one of the following:

[0082] The starting position of the reference signal;

[0083] The end position of the reference signal;

[0084] Time window of the reference signal;

[0085] The duration of the reference signal;

[0086] The reference signal transmission period;

[0087] The number of reference signals sent;

[0088] The reference signal transmission interval;

[0089] Repeated transmission of reference signal information.

[0090] It should be noted that the reference signal in the embodiment of the present application may refer to all reference signals during the transmission process, such as all SSBs sent by the network side triggering an on-demand SSB; it may also refer to a reference signal within a cycle, such as one or more SSB burst sets; it may also refer to a reference signal of a specific index, such as the SSB of SSB index#0 in the SSB burst set.

[0091] In the embodiment of the present application, the starting position of the reference signal can indicate when the reference signal starts to be sent in terms of timing, and the ending position of the reference signal can indicate when the reference signal starts to be sent in terms of timing; the time window of the reference signal can indicate the starting time and ending time of the reference signal transmission, that is, a specific time window can be defined; the duration of the reference signal can indicate the duration of the reference signal transmission, etc.; the transmission period of the reference signal can indicate a specific period performance, and the number of reference signals transmitted can be defined as a specific number; the transmission interval of the reference signal can indicate the interval length between two adjacent reference signals, such as the interval between SSBs or the interval between SSB burst sets; the repetition information of the reference signal can indicate whether the reference signal is repeatedly transmitted, and can indicate the number of repetitions. The above parameters in the transmission pattern of the reference signal can all indicate the time-frequency resource where the reference signal is located. If the above parameters are sent to the user equipment, after the user equipment learns the above parameters, it can receive the reference signal on the corresponding time-frequency resource.

[0092] In some embodiments, the reference signal is usually sent in a signal group (set) manner, that is, for an SSB signal, the reference signal sent in a group can be called an SSB burst set.

[0093] In an embodiment of the present application, repeated transmission of reference signals may be permitted, i.e., one or more reference signals may be transmitted within a certain time period, for example, more than one SSB burst set may be transmitted within an SSB period, or further, a single signal unit within a reference signal transmitted in a group may be repeatedly transmitted, for example, SSB index #0 may be transmitted more than once within an SSB burst set. The purpose of adopting such repeated transmission is to enable the user equipment to more quickly receive multiple specific reference signals for performing measurement, synchronization, automatic gain control, etc.

[0094] In some embodiments, the transmission pattern of the reference signal may further satisfy at least one of the following:

[0095] The duration of the reference signal is greater than a preset length threshold;

[0096] The number of reference signals sent is greater than the preset number threshold;

[0097] The signal sending interval is greater than the preset interval threshold.

[0098] The aforementioned preset threshold values ​​are set on the network-side device primarily to ensure that the signal meets the requirements for measurement on the user device. For example, the preset length threshold is set to ensure that the minimum length requirement for the signal can be measured on the user device is met. The preset interval threshold is set to meet the time interval requirement for processing signals when performing measurements on the user device and cannot be set too short. The preset number threshold is set to meet the minimum number of signals required when performing measurements on the user device. Each of the aforementioned thresholds can be defined by the protocol or pre-configured on the network-side device. This ensures that when the network-side device sends a reference signal, it will send an on-demand reference signal in accordance with the aforementioned requirements. In this case, the reference signal received by the user device also meets the aforementioned requirements, allowing for smooth measurement.

[0099] In the above embodiments of the present application, the first measurement window, the second measurement window, and the transmission pattern of the reference signal all involve a starting position and an ending position, etc. In the embodiments of the present application, the above-mentioned starting position can be an absolute position or a relative position; and / or, the ending position can also be an absolute position or a relative position.

[0100] The absolute position can be defined by time or frame position; the reference position can also be defined by time or frame position. For example, the frame sequence number (SFN) and subframe index (subframe index) can be used to define the starting position and the ending position, which is equivalent to an absolute position; the starting position and the ending position can also be defined by the reference time + offset time (offset), where the reference time can be the time of receiving the first configuration information, or other absolute position. In addition, the reference time can also be a time that is offset by a certain time relative to a certain absolute time.

[0101] The description of the starting position and ending position in the embodiments of the present application applies to the starting position and ending position of each reference signal in the above embodiments, and also applies to the starting position and ending position of various measurement windows, such as the starting position and ending position of the first measurement window and the second measurement window described above. When the reference signal transmission pattern is used to indicate the reference signal transmission position, it primarily notifies the user equipment, but does not explicitly specify the measurement behavior required by the user equipment, unlike a measurement window. Instead, the user equipment is required to independently determine whether to perform reception and how to receive the reference signal based on the reference signal transmission position indicated by the reference signal transmission pattern.

[0102] The content of the first configuration information provided in each embodiment of the present application specifically stipulates or suggests how to efficiently and accurately receive the reference signal, which is equivalent to defining one or more measurement objects. Therefore, the above provisions or suggestions can also be constructed into at least one measurement object for use.

[0103] In some embodiments, as described above, the first measurement configuration information may also include a measurement activation indication of the first measurement configuration information. In this case, the activation object indicated by the measurement activation indication may include at least one of the measurement object, SMTC, the first measurement window, and the transmission pattern of the reference signal. Generally speaking, as described in the above embodiments, the first measurement configuration information may include at least one of the above-mentioned measurement objects, SMTC, the first measurement window, and the transmission pattern of the reference signal. Therefore, the activation indication sent subsequently may be to activate at least one of them.

[0104] Specifically, the activation indication in the above embodiment of the present application can be a displayed activation indication or an implicit activation indication, that is, it is not directly or exclusively used to activate one of the activation objects, but may be a notification message of other events, and the user equipment is predefined to activate one of the first measurement configuration information after receiving the above notification message. In addition, in the specific implementation process, a technical solution combining displayed indications and implicit indications can also be adopted. For example, when configuring the secondary cell (Scell), the network side device configures the transmission pattern of multiple SSBs in the first measurement configuration information or measurement object sent, including a specific transmission period or transmission start position, etc. At this time, after receiving the first measurement configuration information, the user equipment considers that the network side device starts to send SSB according to the first transmission pattern, and therefore performs reception and measurement according to the first transmission pattern, which is equivalent to implicit indication activation; and when the user equipment receives the activation command of a secondary cell, it performs reception and measurement according to the second transmission pattern, thereby completing the activation process of the secondary cell, which is equivalent to an explicit indication activation; when the user equipment completes the activation process of the secondary cell, it considers that the network side device starts to send SSB according to the third transmission pattern, and therefore performs reception and measurement according to the third transmission pattern, which is equivalent to implicit indication activation. It should be noted that the order and steps mentioned above are optional.

[0105] In addition, in some embodiments, the content included in the above-mentioned activation object may include at least one of an identifier of the activation object, the number of activation objects, or a range of the activation objects in the activation indication.

[0106] The identifier of the activation object can specifically identify the activation object to be activated. For example, when a certain type of activation object that can be activated in the first configuration information includes multiple activation objects, such as multiple reference signal transmission patterns, a corresponding identifier can be set for each transmission pattern, that is, the identifier of the activation object; for the measurement object, a corresponding identifier can also be set, and the SMTC and the first measurement window can also be set with corresponding identifiers, so that a specific activation object can be indicated;

[0107] The number of activated objects refers to the specific limit on the number of activated objects when there are repeatable activated objects, such as SMTC and the first measurement window;

[0108] The scope of the activated object can be at least one of the position range, quantity range, etc. of the activated object. For example, in the case where there are multiple measurement objects and multiple reference signal transmission patterns, the scope of the activated object is to select a specific measurement object or reference signal transmission pattern; and for cases such as SMTC or the first measurement window, the scope of the activated object can specifically limit which positions of the SMTC or the first measurement window are selected for reception and measurement, and the position range can be a time range or a frame range.

[0109] In addition to including the activation indication in the first information to activate the measurement object, the network-side device may, in some cases, continue to send a deactivation indication. Specifically, the method may further include:

[0110] The user equipment receives a deactivation indication of the first measurement configuration information sent by the network side device, where the deactivation indication includes at least one of a deactivation measurement object indication, a deactivation SMTC indication, a deactivation first measurement window indication, or a deactivation reference signal transmission pattern indication, corresponding to the case where at least one of the measurement object, SMTC, first measurement window, and reference signal transmission pattern is activated in the activation indication. For example, after the network side activates the reference signal sent on demand, the user equipment may consider that the reference signal sent on demand has been sent until the deactivation indication is received.

[0111] In some embodiments, the first information may be sent in multiple ways. For example, the network side device may send the information through physical layer signaling, media access control layer signaling, or downlink radio resource control signaling. In this case, the user equipment in the embodiment shown in FIG. 2 receives the first information sent by the network side device. Specifically, the following steps may be performed:

[0112] The user equipment receives first information sent by the network side device through physical layer signaling (MAC CE signaling), media access control layer signaling (DCI signaling), or downlink radio resource control signaling (RRC signaling). Optionally, a reference signal transmission pattern can be directly sent through any of the above signaling to convey specific transmission information of the on-demand reference signal (on-demand SSB) to the user equipment.

[0113] Alternatively, in some embodiments, the above-mentioned activation indication and deactivation indication may also be sent using the above-mentioned physical layer signaling (MAC CE signaling), media access control layer signaling (DCI signaling) or downlink radio resource control signaling (RRC signaling).

[0114] Specifically, the first information may be sent by media access control layer signaling (DCI signaling) in multiple ways, for example:

[0115] First, a specific Radio Network Temporary Identifier (RNTI) identifier can be scrambled (CRC scrambled by), and this RNTI uses different values ​​to represent a measurement activation indication or a deactivation indication; if it carries the first measurement configuration information, this RNTI can identify that the control information sent is the first measurement configuration information; if it carries a reference signal transmission pattern, this RNTI can identify that the control information sent is a reference signal transmission pattern.

[0116] Second, it can show whether there is indication information in the configuration DCI;

[0117] Third, the existing indication fields in the DCI can be reinterpreted;

[0118] Fourth, you can use scheduled DCI or non-scheduled DCI;

[0119] Fifth, dedicated DCI can be configured for the user equipment, i.e., UE-specific DCI, for example, carried in uplink scheduling DCI such as DCI 0_0 / 0_1 / 0_2 or carried in downlink scheduling DCI such as DCI 1_0 / 1_1 / 1_2;

[0120] Sixth, a group-specific DCI, namely Group common DCI, can be configured. Optionally, a block in the group common DCI corresponds to a specific user device, a specific cell or a specific cell group; and / or, optionally b indicates different target cells for different user devices, and the indication information is reflected in the block, or a unified cell list is indicated to indicate which cells do not need to be measured to different user devices.

[0121] For the physical layer signaling (MAC CE signaling) sending the first information, it can also include multiple ways, such as taking the activation indication / deactivation indication of the measurement object MO as an example, it can also be a cell, SMTC, etc., including at least one of the following

[0122] First, the LCID field is used to indicate that the MAC CE is used to send an activation indication / deactivation indication, which may specifically be an activation / deactivation measurement object, a cell, or an SMTC;

[0123] Second, the meas ID field is used to indicate activation / deactivation of the measurement object associated with the meas ID indicated by the meas ID; for example, X bits are used to indicate the meas ID; or N bits are used for bit mapping of the meas ID;

[0124] Third, use the MO field: used to indicate the activation / deactivation status of the measurement object MO;

[0125] Fourth, use the A / D field: used to indicate whether the measurement object indicated by the previous meas ID field / MO field is activated or deactivated.

[0126] For sending the first information through RRC signaling, RRC reconfiguration information or RRC resume information can be used.

[0127] The above is mainly explained by taking the case where the activation indication or the deactivation indication is transmitted by physical layer signaling (MAC CE signaling), media access control layer signaling (DCI signaling) or downlink radio resource control signaling (RRC signaling) as an example. For other information, such as the reference signal transmission pattern or the first measurement configuration information, any of the above-mentioned achievable methods can be selected. In some embodiments, for the case where the reference signal transmission pattern is directly included in the first information, or the reference signal transmission pattern is included in the first measurement configuration information, or the reference signal transmission pattern is included in the first indication information, the first information can be set to include N reference signal transmission periods, where N is an integer greater than 1. At this time, for the user equipment, when it receives the reference signal sent on demand based on the first information, it considers that the period of the reference signal sent on demand is different at different times. Specifically, step 202 in the embodiment shown in Figure 2 may include at least one of the following:

[0128] After receiving the first information, the user equipment receives the reference signal according to the first transmission cycle of the N reference signal transmission cycles starting from the first moment;

[0129] After receiving the first information, the user equipment receives the reference signal according to the first transmission period of the N reference signal transmission periods from the first moment until the second moment;

[0130] The user equipment receives the reference signal according to the second transmission period of the N reference signal transmission periods starting from the second moment;

[0131] The user equipment receives the reference signal according to the second transmission period of the N reference signal transmission periods starting from the second moment until the third moment;

[0132] The user equipment receives the reference signal according to the third transmission cycle of the N reference signal transmission cycles starting from the third moment;

[0133] The user equipment receives the reference signal according to the third transmission period of the N reference signal transmission periods starting from the third moment until the fourth moment.

[0134] Through the above embodiments, the network can adjust the reference signal transmission period in different time periods based on the needs or purposes of reference signal transmission, achieving flexible reference signal transmission and further improving network energy conservation. Furthermore, when receiving the reference signal for each transmission period, the user equipment can set only the start time of reception. In this case, the user equipment can remain in the receiving state for a long time and receive reference signals from multiple transmission periods. Alternatively, both the start time and the end time of reception can be set.

[0135] In the embodiment of the present application, for the specific settings of the above-mentioned first moment, second moment, third moment, and fourth moment, on the one hand, it is necessary to keep the above-mentioned first moment, second moment, third moment, and fourth moment in chronological order, that is, the first moment, second moment, third moment, and fourth moment need to be arranged in chronological order. In addition, the specific values ​​of the above-mentioned four moments can be one of the following moments:

[0136] the moment of receiving the first message;

[0137] a time after a specific interval after receiving the first message;

[0138] The moment of receiving the secondary cell activation command;

[0139] A time after a specific interval of receiving a secondary cell activation command;

[0140] The moment when the secondary cell activation is completed;

[0141] A time before or after a specific interval when activation of the secondary cell is completed;

[0142] The time when the secondary cell is deactivated;

[0143] A time before or after a specific interval when deactivation of the secondary cell is completed;

[0144] the time indicated by the first information;

[0145] The time when the network-side device is configured;

[0146] Predefined moments.

[0147] The time when the network side device is configured may also include a pre-configuration situation.

[0148] For example, in some embodiments, the user equipment may assume that the reference signal will be transmitted according to the first transmission period indicated by the first information at the time of receiving the first information or at a time after a specific interval. Upon receiving the secondary cell activation command, the user equipment may assume that the reference signal will be transmitted according to the second transmission period indicated. After the secondary cell activation is completed, the user equipment may assume that the reference signal will be transmitted according to the third transmission period indicated. After the secondary cell is deactivated, the user equipment may assume that the reference signal will be transmitted according to the fourth transmission period indicated. It is understood that only some of the above steps may be present. For another example, in some embodiments, the user equipment may assume that the reference signal will be transmitted according to the first transmission period indicated by the first information at the time of receiving the first information or at a time after a specific interval. Upon receiving the secondary cell activation command, the user equipment may assume that the reference signal will be transmitted according to the second transmission period indicated. For another example, the user equipment may assume that the reference signal will be transmitted according to the first transmission period indicated by the first information at the time of receiving the first information or at a time after a specific interval. Upon receiving the secondary cell activation command, the user equipment may assume that the reference signal will be transmitted according to the second transmission period indicated. For another example, the user equipment may assume that the reference signal will be transmitted according to the first transmission period indicated before receiving the secondary cell activation command and will be transmitted according to the second transmission period indicated after receiving the activation command.

[0149] In some embodiments, in step 202 shown in FIG. 2 above, the user equipment receives a reference signal sent on demand based on the received first information to perform measurement, synchronization, etc. In order to control the reception and measurement process of the user equipment, certain conditions can be set, that is, a first condition is set. When the first condition is met, the measurement of the reference signal is started; when the second condition is met, the measurement of the reference signal is stopped. Specifically, depending on the actual situation, multiple conditions can be selected as the first condition in the embodiment of the present application. Specifically, the first condition can include at least one of the following:

[0150] reaching the measurement start time indicated in the first measurement configuration information or the activation indication;

[0151] After receiving the first measurement configuration information or activation indication, a first set time interval is reached;

[0152] No later than a second set time interval after receiving the first measurement configuration information or the activation indication;

[0153] No later than a third set time interval after receiving the first measurement configuration information or the activation indication, and / or no earlier than a fourth set time interval after receiving the first measurement configuration information or the activation indication.

[0154] That is, the measurement start time can be specifically indicated in the first measurement configuration information or the activation indication, which is a way of displaying the indication, or an implicit indication scheme is adopted, that is, it is pre-set to be when the first set time interval is reached after receiving the first measurement configuration information or the activation indication, as satisfying the first condition; or, in some other cases, the latest time for performing the measurement can also be limited, for example, the second set time interval after receiving the first measurement configuration information or the activation indication is used as the first condition; or, the earliest time for performing the measurement can also be limited, for example, the fourth set time interval after receiving the first measurement configuration information or the activation indication is used as the first condition; or, in combination with the above-mentioned two situations of not later than and not earlier than, not later than the third set time interval after receiving the first measurement configuration information or the activation indication and not earlier than the fourth set time interval after receiving the first measurement configuration information or the activation indication are used as the above-mentioned first condition, limiting the start of measurement of the reference signal within a certain time period.

[0155] Specifically, according to different actual situations, various conditions may be selected as the second condition in the embodiment of the present application. Specifically, the second condition may include at least one of the following:

[0156] Receiving an activation instruction of a secondary cell;

[0157] reaching the measurement stop time indicated in the first measurement configuration information or the activation indication;

[0158] After receiving the first measurement configuration information or the activation indication, a fifth set time interval is reached;

[0159] After starting to measure the reference signal, a sixth set time interval is reached;

[0160] After the first reference signal is measured, the seventh set time interval is reached;

[0161] The timer expires, and the timer is started when the first measurement configuration information or activation indication is received or when the measurement of the reference signal is started, or the timer is started when the eighth time interval is reached after the first measurement configuration information or activation indication is received, or when the ninth time interval is reached after the measurement of the reference signal is started.

[0162] That is, in some cases, if the secondary cell is activated, the reception and measurement of the reference signal can be stopped, so it can be used as a case of stopping measurement, and the measurement can also be stopped according to the time indicated in the first measurement configuration information or the activation indication; or according to the agreed time interval after receiving the first measurement configuration information or the activation indication, that is, the fifth time interval, the measurement can be stopped; or a certain measurement execution time is set, that is, after starting the measurement of the reference signal, it reaches the sixth set time interval; or according to the actual measurement of the first reference signal, a certain measurement execution time is set, for example, reaching the seventh set time interval; or a timer is used. If the timer expires and it is considered that the second condition is met, the start time of the timer can be when the first measurement configuration information or the activation indication is received or when the measurement of the reference signal is started; or when the eighth time interval is reached after the first measurement configuration information or the activation indication is received; or when the ninth time interval is reached after starting the measurement of the reference signal.

[0163] In some embodiments, the user equipment's control over the reception and measurement of the reference signal may also be reflected in limiting the number of receptions, the number of receptions, the reception duration, or whether the test reporting requirements of the specific reference signal are met, and setting a corresponding expected value to expect the user equipment to be able to execute, for example, the user equipment may receive the reference signal sent on demand based on the reception of the first information, including at least one of the following:

[0164] The user equipment performs reception on all reference signals sent on demand;

[0165] The user equipment performs reception on the reference signal sent on demand at least a preset number of times;

[0166] The user equipment performs reception for at least a preset time length on the reference signal sent on demand;

[0167] The user equipment receives measurement reports at least a predetermined number of times on the reference signal sent on demand;

[0168] The user equipment receives at least a preset number of reference signals on the reference signal sent on demand.

[0169] In the embodiment of the present application, if the purpose of receiving the reference signal is to perform measurement, the received reference signal will be used for subsequent measurements. The limitations on the number of receptions, the number of receptions, the length of reception time, etc. in the embodiment of the present application can also be regarded as limitations on the measurement, especially whether the preset number of measurement reports are met.

[0170] The measurement report that meets at least the preset number of times is mainly because the user equipment may need to measure multiple reference signals to implement a measurement report. Therefore, the preset number of measurement reports can be set to limit the measurements that need to be performed to meet at least the preset number of measurement reports.

[0171] Furthermore, in an embodiment of the present application, although the network-side device sends a message to the user instructing the user to perform actions such as measurement based on the transmitted reference signal, a certain preset condition may be set on the user device, and the user device will only receive the on-demand reference signal after determining that the preset condition is met. Specifically, the user device may confirm that the first information is associated with a secondary cell that meets the first preset condition, or the user device may confirm that the first information is associated with a measurement object that meets the second preset condition.

[0172] FIG3 is a flow chart of another reference signal processing method according to an embodiment of the present application. As shown in FIG3 , based on the embodiment shown in FIG2 , the method further includes step 203 before step 202:

[0173] Step 203: The user equipment confirms that the first information is associated with a secondary cell that meets a first preset condition, or the user equipment confirms that the first information is associated with a measurement object that meets a second preset condition.

[0174] For other steps 201 and 202, please refer to the description in the above embodiment for details.

[0175] In step 203, in some cases, that is, when it is necessary to perform operations such as reference signal measurement on the secondary cell based on whether there is a need, specifically, the first preset condition may include that the secondary cell supports on-demand transmission of reference signals or the secondary cell is in a deactivated state; or in other cases, certain conditions may also be set for the measurement object, for example, measurement can only be performed if the second preset condition is met, and the above-mentioned second preset condition is associated with a reference signal sent on demand, or a measurement object specified by the network side.

[0176] FIG4 is a flow chart of another reference signal processing method according to an embodiment of the present application. The scenario implemented in this embodiment is an application scenario in which a user equipment receives a reference signal based on first information and performs measurement. As shown in FIG4 , the method further includes steps 204 to 206 based on the embodiment shown in FIG2 . As shown in FIG4 , the method includes the following steps:

[0177] Step 201: Receive first information sent by a network-side device, where the first information includes at least one of first measurement configuration information, an activation indication of the first measurement configuration information, and a reference signal transmission pattern;

[0178] Step 202: Receive a reference signal sent on demand based on the first information to perform measurement;

[0179] For the introduction of the above steps 201 and 202, please refer to the above embodiments. In this embodiment, the following steps are mainly added:

[0180] Step 204: Send a measurement report to the network side device. When the first information sent by the network side device to the user equipment is associated with at least one cell, the measurement report may include at least one of the following:

[0181] Measurement results of all associated cells;

[0182] Measurement results of cells with measurement values ​​higher than a preset threshold;

[0183] measurement results of cells whose measurement value ranking is greater than a first preset value;

[0184] The measurement result of the cell with the best measurement value;

[0185] measurement results of cells whose configuration order is greater than a second preset value;

[0186] The measurement results of the cells recommended for activation.

[0187] In some embodiments, uploading the above-mentioned measurement includes consuming certain reporting resources. If the available reporting resources have been pre-configured, the user equipment can directly use the above-mentioned reporting resources to report the measurement report. However, in some cases, it is necessary for the network side to report and send reporting resource indication information. Therefore, before the above-mentioned step 204, step 205 can also be included, in which the user equipment receives the reporting resource indication information reported and sent by the network side;

[0188] This step can be when the network side device has not pre-configured reporting resources for user reporting, or when there are requirements for resources reported by the user device, and reporting resource indication information can be sent to the user device. The reporting resource indication information will specifically limit the reporting resources that the user device can use for reporting.

[0189] In this case, the above step 204 may specifically include: the user equipment determines the measurement report according to the above reporting resource indication information;

[0190] In the above steps, if the user equipment performs measurement based on the received on-demand reference signal, it can obtain measurement results related to the reference signal measurement, and then generate a measurement report based on the measurement results. The measurement report can be reported to the network side device.

[0191] Furthermore, in step 205, after receiving the reporting resource indication information, the user equipment has determined the indicated reporting resources. In some cases, if the reporting resources allocated to the user equipment by the network device are limited, the user equipment may need to control the size of the measurement report ultimately generated, and may also need to reduce the number of bytes in the measurement report to complete the report using fewer reporting resources. In this case, when generating the content of the measurement report, less content may be selected to reduce the number of bytes in the measurement report.

[0192] When the terminal measures multiple cells, it needs to determine how to report the measurement results. The simplest case is to report the measurement results of all cells. Compared with the measurement report including the measurement results of all associated cells, the measurement value threshold and the measurement value ranking can be set to be greater than the first preset value, so that only the measurement results of some associated cells can be selected; the configuration order refers to the order in which the first information lists the cells that need to perform reference signal measurement, and the measurement results of some associated cells can be selected; when the cell with the best measurement value is selected, the measurement result of the best cell in the associated cells is selected; the measurement result of the recommended activation cell gives the user equipment the right to recommend activation, and the user equipment reports the recommended activation cell, and in this case, only the cell identifier can be included.

[0193] Specifically, in the embodiment of the present application, the measurement results of each cell obtained by the user equipment may include at least one of a measurement value, a cell identifier, and a measurement object identifier; and when it is necessary to generate a measurement report based on the above-mentioned measurement results, the measurement report may be generated based on the measurement results of all the above-mentioned cells, or the measurement results of some cells. Therefore, the number of measurement results included in the generated measurement report can be limited by a preset threshold or a preset value, which can control the size of the measurement report finally generated.

[0194] When the network triggers a user equipment to measure multiple cells, its purpose may be to select some cells from the associated cells reporting measurement results for activation to adapt to changes in downlink traffic. In this case, the network may not need to know the measurement results of all cells. Therefore, the terminal can report the measurement results of only a portion of cells, or even only the final cell identifier, to assist the network in making the selection. Furthermore, the network can inform the user equipment of the final number of activated cells when triggering the measurement or sending the reference signal, helping the user equipment determine the final measurement reporting results and reducing the demand for reporting resources.

[0195] In some embodiments, the demand for reporting resources may be further reduced by increasing the numerical values ​​of the preset threshold, the first preset value, and the second preset value, or by selecting to report the optimal cell measurement result or the measurement result of the recommended activated cell, and for the above-mentioned measurement result, selecting one of the measurement value, the cell identifier, and the measurement object identifier. In this embodiment of the present application, the measurement value includes at least one of reference signal received power, reference signal received quality, and signal-to-interference-plus-noise ratio.

[0196] In the embodiment of the present application, the above-mentioned preset threshold, first preset value, and second preset value may be predefined by the protocol, preconfigured by the network side device, or carried in the information sent by the network side device to the user device. Specifically, it may be the following situations:

[0197] The preset threshold is carried in the first measurement configuration information, carried in the activation indication, or carried in the reported resource indication information;

[0198] The first preset value is carried in the first measurement configuration information, carried in the activation indication, or carried in the reporting resource indication information;

[0199] The second preset value is carried in the first measurement configuration information, carried in the activation indication, or carried in the reporting resource indication information.

[0200] Step 206: The user equipment reports the measurement report to the network side device according to the reporting resource indicated by the reporting resource indication information.

[0201] In an embodiment of the present application, if there is no reporting resource pre-configured for the user device in the network, the user device can actively send a reporting resource request to the network side device according to demand to request reporting resources; for the above-mentioned reporting resource request, it can request the network side to report the allocation of reporting resources by sending a scheduling request (SR) or a buffer status report (BSR) request.

[0202] In an embodiment of the present application, two situations may be included, one of which is that when sending an on-demand reference signal, such as an on-demand SSB, there is no periodic and continuous reference signal transmission, that is, there is no always-on SSB, and the two do not affect each other. The reference signal can be received and measured according to the scheme recorded in the above embodiment, and the measurement results can be reported. In another case, one possibility is that an on-demand reference signal and a periodic and continuous reference signal are sent simultaneously. In this case, the first solution is to receive and measure the two independently without considering their mutual impact. Another possibility is that when the transmission mode of the on-demand reference signal (on-demand SSB) is the same as that of the periodic and continuous reference signal (always-on SSB), the above-mentioned transmission mode may be transmit power, transmit beam, frequency domain position, etc., and the user equipment actually expects or is expected to measure only the on-demand reference signal (on-demand SSB). This is because the periodic and continuous reference signal (always-on SSB) usually has a long transmission period. If the on-demand reference signal (on-demand SSB) meets the measurement requirements, the user equipment does not need to waste additional capabilities to detect the periodic and continuous reference signal (always-on SSB). Of course, if the periodic and continuous reference signal (always-on SSB) falls within the detection range of the on-demand reference signal (on-demand SSB), the user equipment can still measure the periodic and continuous reference signal (always-on SSB), which may be determined by the user equipment implementation.

[0203] Of course, if the user equipment measures both the on-demand reference signal (on-demand SSB) and the periodic and continuous reference signal (always-on SSB) at the same time, it can choose to report independently or uniformly. If it is a unified report, it may be necessary to specify the specific measurement object, such as whether it is an on-demand reference signal (on-demand SSB), a periodic and continuous reference signal (always-on SSB), or both.

[0204] Corresponding to the user equipment side embodiments shown in Figures 2-4 above, the present application also provides an embodiment executed on a network side device. Figure 5 is a flow chart of another reference signal processing method in an embodiment of the present application. The method can be executed in a reference signal processing device, which can be set in a network side device. As shown in Figure 5, the method includes the following steps:

[0205] Step 501: Send first information to a user equipment, where the first information includes at least one of first measurement configuration information, an activation indication of the first measurement configuration information, and a reference signal transmission pattern.

[0206] The technical solution provided in the embodiments of the present application is a technical solution for transmitting reference signals on demand in order to achieve network energy saving in a mobile communication network. If the reference signal is an SSB, the on-demand transmission of the reference signal can be expressed as On-demand SSB. The characteristics of the transmission mode of this type of reference signal can be changing from not transmitting this type of reference signal to transmitting this type of reference signal, from transmitting the reference signal according to one period to transmitting the reference signal according to another period, or a method of transmitting an additional reference signal. Therefore, the network-side device needs to send a corresponding instruction to the user equipment to inform the user equipment how to receive the above-mentioned reference signal.

[0207] In this embodiment of the present application, a network device may send first information to a user equipment to instruct the user equipment on how to receive a reference signal sent on demand. The network device may be a base station of a primary cell serving the user equipment or a base station of an activated secondary cell.

[0208] Specifically, for the network side device, the above-mentioned indication may be sent in three ways, and the first information may include at least one of three different types of indication information. The first type of indication information may refer to the measurement configuration information sent to the user equipment in the prior art and may be implemented compatible with the prior art. For example, the first information includes first measurement configuration information. The first measurement configuration information may be implemented by modifying the existing measurement configuration information. Sending the first measurement configuration information may also be considered as a new measurement configuration or reconfiguration. The second type of indication information indicates that although the network-side device has sent the first measurement configuration information to the user equipment, the first measurement configuration information will not take effect immediately. Instead, all or part of the first measurement configuration information needs to be activated by sending an activation indication for the first measurement configuration information. The activation indication may be an explicit activation indication, an implicit activation indication, or a combination of an implicit activation indication and an explicit activation indication. The third type of indication information directly indicates the sending of information related to a reference signal on demand, such as a reference signal transmission pattern, so that the user equipment can directly understand the reference signal transmission pattern and receive the reference signal on the corresponding time-frequency resource. The user equipment may perform at least one of measurement, synchronization, and automatic gain control adjustment when receiving the reference signal sent on demand based on the first information.

[0209] The technical solution provided in the above embodiments of the present application is aimed at achieving network energy saving on network side devices by sending reference signals in an on-demand manner, thereby reducing energy consumption and meeting the demand for network energy saving. The technical solution includes at least one of first measurement configuration information, an activation indication of the first measurement configuration information, or a reference signal transmission pattern in the first information sent to the user equipment to notify the user equipment, thereby enabling the user equipment to successfully receive at least part of the reference signal according to the above first information and perform at least one of measurement, synchronization, and automatic gain control. Therefore, when the reference signal is sent in an on-demand manner for network energy saving, the reference signal can also be successfully received and subsequently processed on the user equipment, providing an effective solution.

[0210] The following embodiments will respectively introduce and illustrate in detail the three types of indication information included in the first information. Specifically, the first measurement configuration information may include at least one of the following:

[0211] The number of synchronization signal block measurement time indication SMTC;

[0212] Minimum number of SMTC measurements;

[0213] a transmission pattern of a reference signal;

[0214] A measurement object, used to indicate measurement of a reference signal sent on demand;

[0215] a first measurement window, the first measurement window being determined by at least one of a start position, an end position, and a measurement window length;

[0216] The first indication information is used to indicate a measurement object identifier or a measurement identifier in the second measurement configuration information received by the user equipment.

[0217] In some embodiments, the transmission pattern of the reference signal includes at least one of the following:

[0218] The starting position of the reference signal;

[0219] The end position of the reference signal;

[0224] The reference signal transmission interval;

[0225] Repeated transmission of reference signal information.

[0226] In addition, at least one of the following is met:

[0227] The duration of the reference signal is greater than a preset length threshold;

[0228] The number of reference signals sent is greater than a preset number threshold;

[0229] The reference signal sending interval is greater than the preset interval threshold.

[0230] In some embodiments, the first indication information further includes:

[0231] A second measurement window, and parameter information of the second measurement window.

[0232] The parameter information of the second measurement window includes at least one of the following:

[0233] The number of second measurement windows;

[0234] a measurement window length of the second measurement window;

[0235] a measurement period of a second measurement window;

[0236] The position of the second measurement window in each measurement cycle. In the embodiment of the present application, for a detailed introduction to each item in the first configuration information, as well as a detailed introduction to the reference signal transmission pattern and the first indication information, please refer to the embodiment shown in FIG2 above.

[0237] In some embodiments, the activation object indicated by the activation indication of the above-mentioned first configuration information includes at least one of a measurement object, an SMTC, a first measurement window, and a transmission pattern of a reference signal; the activation indication of the first measurement configuration information includes at least one of an identification of the activation object, the number of activation objects, or a range of the activation object.

[0238] In the embodiment of the present application, for a detailed introduction to the activation indication of the first measurement configuration information, please refer to the embodiment shown in FIG. 2 above.

[0239] In addition to including the activation indication in the first information to activate the measurement object, the network-side device may, in some cases, continue to send a deactivation indication. Specifically, as shown in FIG6 , based on the embodiment shown in FIG5 , the method may further include:

[0240] Step 502: Send a deactivation indication to the user equipment, where the deactivation indication includes at least one of a deactivation measurement object indication, a deactivation SMTC indication, a deactivation first measurement window indication, or a deactivation reference signal transmission pattern indication.

[0241] The user equipment receives a deactivation indication of the first measurement configuration information sent by the network side device, where the deactivation indication includes at least one of a deactivation measurement object indication, a deactivation SMTC indication, a deactivation first measurement window indication, or a deactivation reference signal transmission pattern indication, corresponding to the case where at least one of the measurement object, SMTC, first measurement window, and reference signal transmission pattern is activated in the activation indication. For example, after the network side activates the reference signal sent on demand, the user equipment may consider that the reference signal sent on demand has been sent until the deactivation indication is received.

[0242] In some embodiments, the first information may be sent in multiple ways. For example, the network side device may send the information through physical layer signaling, media access control layer signaling, or downlink radio resource control signaling. In this case, the user equipment in the embodiment shown in FIG. 2 receives the first information sent by the network side device. Specifically, the following steps may be performed:

[0243] First information sent by a network device to a user equipment via physical layer signaling, media access control layer signaling, or downlink radio resource control signaling. Optionally, a reference signal transmission pattern may be directly sent via any of the above signaling to convey specific transmission information of an on-demand reference signal (SSB) to the user equipment. The network device herein may refer to a base station on the ground or a base station on a satellite.

[0244] In some embodiments, the network side device may further allocate reporting resources to the user equipment, and send reporting resource indication information to the user equipment in combination with the allocated reporting resources. Specifically, as shown in FIG. 7 , based on FIG. 2 above, the following steps may be further included:

[0245] Step 503: Receive a measurement report reported by the user equipment, where the measurement report is determined by the user equipment based on the reported resource indication information.

[0246] The user equipment may perform measurement based on the received reference signal to obtain a corresponding measurement result, and when the first information sent to the user equipment includes at least one associated cell, the content included in the measurement report may include one of the following:

[0247] Measurement results of all associated cells;

[0248] Measurement results of cells with measurement values ​​higher than a preset threshold;

[0249] measurement results of cells whose measurement value ranking is greater than a first preset value;

[0250] The measurement result of the cell with the best measurement value;

[0251] measurement results of cells whose configuration order is greater than a second preset value;

[0252] The measurement results of the cells recommended for activation.

[0253] In some cases, it is necessary to send reporting resource indication information to the user equipment to indicate the reporting resources, so that the user equipment can control the reporting content in combination with the reporting resource situation indicated by the network side device to obtain a measurement report that matches the allocated reporting resources. Therefore, the following steps may also be included:

[0254] Step 504: Send reporting resource indication information to the user equipment; the reporting resource indication information may indicate the reporting resources specifically allocated to the user equipment.

[0255] Furthermore, the sending of the resource reporting indication information to the user equipment may be based on a resource reporting request sent by the user equipment to request resource reporting.

[0256] In the embodiments of the present application, for a specific introduction to receiving a resource reporting request sent by a user equipment, sending resource reporting indication information to the user equipment, and the user equipment determining a measurement report based on the resource reporting indication information, please refer to the above-mentioned embodiments on the user equipment side, which will not be repeated in the embodiments of the present application.

[0257] The above embodiments of the present application are further summarized and explained below through implementation modes one to four.

[0258] Embodiment 1 of the present invention: Implementation method of network-side device indicating on-demand SSB

[0259] A key feature of on-demand SSB is changes in the SSB transmission state, such as changing from no SSB transmission to SSB transmission, changing from one cycle to another, or sending additional SSBs. One way to notify the user equipment of such changes is through network-side indication.

[0260] Network-side device indications can be divided into the following three directions:

[0261] 1. Configuration / reconfiguration indication via measurement configuration information

[0262] 2. Activate or deactivate existing configurations

[0263] 3. Directly instruct on-demand SSB to send relevant information

[0264] In the first direction, the configuration / reconfiguration of measurement configuration information can reuse the mechanism of the existing protocol as much as possible, as shown in the second embodiment for details.

[0265] The second direction can be achieved by activating or deactivating existing configuration information. Specifically:

[0266] 1. The user equipment believes that the network equipment's measurement configuration and other information must be activated before it can take effect. For example, when the network equipment configures a secondary cell (Scell) for the user equipment, it also configures a serving cell measurement object (serving cell MO). However, the user equipment believes that this configuration information is not yet effective. The user equipment then resumes measurement after receiving further activation information. This activation information can be activation information for the serving cell measurement object (serving cell MO) or activation information for the SMTC within the serving cell measurement object (serving cell MO), specifically specifying which SMTCs to activate for measurement, the starting time, or the time window within which the measurement is to be performed.

[0267] 2. The measurement configuration information of the network side device can be considered to be implicitly activated or implicitly plus explicitly activated. For example, when the network side device configures the secondary cell Scell ​​(in the measurement configuration information or MO), it configures the transmission patterns (period, starting position, etc.) of multiple SSBs. At this time, after receiving the measurement configuration information, the user equipment believes that the network side device starts to send SSBs according to the first transmission pattern, and therefore performs measurements according to the first transmission pattern, which is equivalent to implicit activation; and when the user equipment receives the secondary cell Scell ​​activation command, it performs measurements according to the second transmission pattern, thereby completing the secondary cell Scell ​​activation process; when the user equipment completes the secondary cell Scell ​​activation process, it believes that the network side device starts to send SSBs according to the third transmission pattern, and therefore performs measurements according to the third transmission pattern. It should be noted that the above-mentioned order and steps are optional.

[0268] The third direction is that the network side equipment directly indicates the on-demand SSB transmission pattern and other related information through DCI / MAC CE, RRC and other signaling. After receiving the signaling instruction, the user equipment performs measurement according to the instruction information.

[0269] Implementation Method 2 of the Present Invention: Implementation Method of Measurement Configuration

[0270] The network-side device can trigger the user equipment to measure on-demand SSB through measurement configuration.

[0271] 1. Since the transmission pattern of on-demand SSB may be different from that of existing SSB, it is first possible to consider configuring a measurement object MO corresponding to at least on-demand SSB to the user equipment.

[0272] a) In the existing protocol, the user equipment will perform measurements according to the SMTC configured in the MO. Since on-demand SSB may be a short-term or one-shot transmission mode, performing measurements according to the SMTC may cause the user equipment to perform unnecessary measurements, so other information needs to be indicated. For example, implicitly or explicitly indicating to the user equipment the number of SMTCs that need to be measured, or the time domain range of SMTCs within which the measurements are performed. At the same time, the period, duration, etc. of the SMTC may need to allow more possible values ​​to meet the measurement requirements of on-demand SSB, such as a smaller period, a longer duration, etc.

[0273] b) To enable UEs to more accurately measure on-demand SSBs and avoid unnecessary measurements, consider directly indicating a specific measurement range and on-demand SSB information, such as the period, number of transmissions, and other transmission pattern information, to the UE in the MO. This solution is more suitable for non-periodic measurements under on-demand SSBs.

[0274] 2. Since there may be always-on SSBs being sent in the system, the network-side device may have already configured the user equipment with MO information. It is possible to consider reusing some information of the existing MO during configuration, that is, associating the measurement configuration information with the existing MO. At this time, some additional information can be indicated / configured, which is related to the sending of on-demand SSBs to assist the user equipment in performing measurements. For example, a new or additional SMTC is indicated, and the user equipment performs on-demand SSB measurements based on this SMTC. For another example, a new SMTC duration is indicated, or activation / deactivation information of the SMTC is indicated.

[0275] Embodiment 3 of the present invention: User equipment measurement behavior of on-demand SSB

[0276] After receiving the measurement configuration from the network side device, the user equipment determines a specific behavior for performing the measurement.

[0277] 1. No always-on SSB is sent on the secondary cell Scell

[0278] Since on-demand SSB may be a non-periodic transmission, the network side equipment sends some SSBs in a short period of time and then stops sending them. Therefore, if the user equipment wants to complete the measurement behavior, it needs to have some measurement-related requirements. The measurement behavior meets at least one of the following

[0279] a) The UE is (expected to) perform all measurements on the reference signals associated with the measurement configuration information

[0280] b) The UE is (expected to) perform at least N measurements on the reference signal associated with the measurement configuration information

[0281] c) The UE is (expected to) perform measurements on the reference signal associated with the measurement configuration information for a period of at least T

[0282] d) The user equipment is (expected to) perform measurements that meet at least N times of L1 / L3 measurement reporting on the reference signal associated with the measurement configuration information.

[0283] e) The user equipment is (expected to) perform measurements on the reference signals associated with the measurement configuration information, including at least M reference signals.

[0284] 2. Always-on SSB is sent on Scell

[0285] At this point, we can consider whether the user equipment needs to measure both on-demand SSB and always-on SSB at the same time. One possibility is to perform the two measurements independently without considering the mutual impact. Another possibility is that when there is on-demand SSB (and the transmission mode of on-demand SSB is the same as that of always-on SSB, such as transmit power, transmit beam, frequency domain position, etc.), the user equipment (expecting / expected) only measures on-demand SSB. This is because always-on SSB usually has a long period. If on-demand SSB meets the measurement requirements, the user equipment can detect always-on SSB without wasting extra capacity. Of course, if the always-on SSB falls within the detection range of on-demand SSB, the user equipment can still measure always-on SSB, which may be determined by the user equipment implementation.

[0286] When the user equipment measures on-demand SSB and always-on SSB at the same time, if the measurement results are reported

[0287] Optionally, when reporting measurement results, the reports may be submitted independently or in a unified manner. If the reports are submitted in a unified manner, the specific measurement object may need to be specified, such as whether it is always on SSB, on-demand SSB, or both.

[0288] Embodiment 4 of the present invention: User equipment reporting behavior when configuring multiple secondary cells (Scells) for measurement

[0289] To improve downlink service efficiency, network equipment activates some Scells based on service needs. Naturally, higher Scell ​​communication quality contributes more to service transmission. Therefore, before activating a Scell, the network equipment can trigger the user equipment to measure multiple Scells. Based on the measurement results, the network equipment determines the most appropriate Scell ​​to activate.

[0290] Therefore, when the network-side device triggers the user equipment to measure multiple Scells, it is necessary to consider how to perform measurement reporting.

[0291] 1. The user equipment reports the measurement results of all cells

[0292] 2. The user equipment only reports the measurement results of cells above the threshold

[0293] i. Optionally, the threshold is carried by the measurement configuration information or the measurement activation information, or by the signaling carried by the network side indicating the reported resources

[0294] 2. Optionally, the above threshold means that the absolute value of the measurement is above the threshold, or the relative value of the measurement is above the threshold

[0295] 3. Optionally, the user equipment reports specific measurement results and / or their associated cell identifiers / MO identifiers

[0296] 4.Optionally, the user equipment only reports the cell identifier

[0297] 3. The user equipment reports the measurement result of the best cell or its cell identifier

[0298] When a user device reports measurement results, if there are no uplink resources, it sends an SR / BSR requesting the network to allocate uplink resources. If uplink resources are available, the user device also reports the measurement results. If the measurement results are for multiple cells, it is necessary to consider how to best report when uplink resources are limited.

[0299] One method is to report in the configured order, reporting as much as possible. The remaining measurement results may be discarded or the network may be requested to allocate uplink resources.

[0300] Another method is to report the measurement results in the order of quality, reporting as much as possible and not reporting the remaining measurement results.

[0301] Another possibility is to report all possible results if possible, otherwise only report the best measurement result or its associated MO / cell identifier, or to discard the available resources and request the network side device to allocate resources.
