Furthermore, a combination of multiple systems (for example, a combination of LTE or LTE-A with 5G) may also be used.

[0194] To reduce network power consumption, the 3rd Generation Partnership Project (3GPP) proposed the concept of on-demand signaling. On-demand signaling refers to a signal that needs to be transmitted based on existing configurations, but network equipment determines not to transmit it for a period of time based on business conditions, power consumption, and other factors.

[0195] In the embodiment of the present disclosure, the on-demand signal may include but is not limited to at least one of the following:

[0196] Synchronization Signal / PBCH Block (SSB);

[0197] System information, including but not limited to System Information Block n (SIBn), where n is a positive integer, for example, SIB1;

[0198] Random Access Channel (RACH).

[0199] Taking the on-demand signal as SSB as an example, as shown in Figure 1B, the terminal periodically receives the corresponding SSB. If the network device stops transmitting the corresponding SSB for a period of time, if the terminal still attempts to receive the SSB during this period, it will increase the complexity of the terminal receiving the signal.

[0200] From another perspective, during the period when the network device stops sending SSB, other corresponding signals, including but not limited to the physical downlink shared channel (PDSCH), physical uplink shared channel (PUSCH), UE-specific search space downlink control information (USS DCI), etc. may not be transmitted. If the above process is an unknown process for the terminal, it will increase the complexity of terminal implementation.

[0201] In the embodiments of the present disclosure, the configuration methods of SSB and SIB1 are first introduced respectively.

[0202] 1. SSB configuration method:

[0203] 11) For cell search:

[0204] SSB uses a fixed pattern. The fixed pattern is related to the subcarrier spacing (SCS) of the carrier and has a period of 20 milliseconds (ms). The specific pattern can be shown in Table 1 below.

[0205] Table 1

[0206] 12) After obtaining SIB1 (through SIB1):

[0207] The above parameters are used to determine the SSB period, ssb-PositionInBurst is used to indicate the index of the actual transmitted SSB in an SSB burst, and the SSB burts are determined based on the above pattern.

[0208] 3) Determine based on the serving cell common configuration (servingcellConfigCommon):

[0209] The corresponding pattern is the same as the SIB1 configuration. Here, the indication is based on the SSB granularity, corresponding to patterns containing 4, 8, and 64 SSBs in the burst (in the license scenario).

[0210] The SSB frequency domain positions are as follows:

[0211] The SSB frequency domain range is determined by the terminal through blind detection of the corresponding SSB in the corresponding frequency domain range. The SSB occupies 20 resource blocks (RBs) in the frequency domain.

[0212] 2. SIB1 configuration method:

[0213] 21) Method 1: Determine based on the master information block (MIB):

[0214] Determined based on pdcch-ConfigSIB1 in the MIB, where pdcch-ConfigSIB1 is used to indicate the DCI format (format) 0_1 (system information radio network temporary identifier SI-RNTI) scrambled control resource set (Control-Resource Set, CORESET) #0 and search space (SearchSpace, SS) #0 for scheduling SIB1, corresponding to the default period of 20ms. The terminal blindly detects the corresponding DCI, obtains the transmission information of SIB1, receives the corresponding PDSCH at the indicated position, and parses the corresponding SIB1.

[0215] 22) Determine based on PDCCH-configCommon in servingCellConfigCommonSIB indicated by SIB1:

[0216] This information includes at least one of the following: searchspace SIB1 configuration, CORESET#0, and SearchSpace#0. It is primarily used for different bandwidth parts (BWPs): an initial downlink BWP (initial DL BWP) and an active BWP. Except for the initial DL BWP, the SCS and cyclic prefix (CP) lengths corresponding to the other BWPs are the same, and the frequency domain range of the active DL BWP includes CORESET#0 or an active BWP on the initial DL BWP.

[0217] 23) Determined based on PDCCH-configCommon within servingCellConfigCommon.

[0218] The determination method is similar to the above method 22, except that the CSS of type 0 (SearchSpace#0 and / or searchspace SIB1) can only be configured based on the primary cell (PCell) of the master cell group (MCG).

[0219] One way to obtain the system information of the secondary cell (SCell) is to obtain it through servingcellConfigCommon, but this method cannot obtain complete system information compared to SIB1. Another way is to obtain it through dedicatedSIB1-Delivery.

[0220] For SSB and SIB1, both are periodically transmitted signals, that is, they need to be transmitted according to a certain period based on the existing transmission configuration. In the embodiment of the present disclosure, the network device can determine not to transmit the signal within a period of time based on business conditions, power consumption, etc. This type of signal is called an on-demand signal.

[0221] In the embodiments of the present disclosure, in order to ensure that the terminal maintains a consistent understanding of the transmission status of the on-demand signal with the network device after the network device changes the transmission status of the on-demand signal, the following information transmission method, device, and storage medium are provided, which reduces the energy consumption of the network device, improves the availability of network energy saving, and also reduces the complexity of terminal implementation.

[0222] FIG2A is an interactive diagram of an information transmission method according to an embodiment of the present disclosure. As shown in FIG2A , the present disclosure embodiment relates to an information transmission method, which includes:

[0223] In step S2101 , the network device 102 determines that the transmission state of the on-demand signal needs to be changed.

[0224] In some embodiments, an on-demand signal refers to a signal that needs to be transmitted based on an existing configuration, but the network device determines not to transmit it within a period of time based on business conditions, power consumption, and other conditions.

[0225] In some embodiments, the on-demand signal may include but is not limited to at least one of the following: a second SSB; a system message; a RACH.

[0226] The second SSB refers to a periodically transmitted SSB. The system message may include but is not limited to SIBn, where n may be a positive integer, such as SIB1.

[0227] In some embodiments, the network device 102 may determine that the transmission state of the on-demand signal needs to be changed based on business conditions, power consumption, etc., and the transmission state of the on-demand signal after the change may be to stop transmission or to transmit.

[0228] In step S2102 , the network device 102 determines a resource location where the first signal is located.

[0229] In some embodiments, the first signal may be used to indicate a change in the transmission status of the on-demand signal.

[0230] In some embodiments, the first signal may include, but is not limited to, any of the following:

[0231] a first reference signal;

[0234] In an example, the first reference signal may include, but is not limited to, any of the following:

[0235] Cell-specific reference signal (CRS);

[0236] Channel State Information-Rreference Signal (CSI-RS).

[0237] The CSI-RS may include but is not limited to a Tracking Reference Signal (TRS).

[0238] Exemplarily, the TRS is a TRS used for cell activation / deactivation.

[0239] Exemplarily, the TRS is a TRS configured based on configuration information sent by the network device, such as SCellActivationRS-Config.

[0240] In an example, the simplified SSB is a signal obtained by simplifying the SSB.

[0241] Exemplarily, the simplified SSB may be a partial signal included in the SSB of the cell where the terminal is located.

[0242] The simplified SSB may include one or two of a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH).

[0243] Exemplarily, the simplified SSB may include any of the following: PSS; SSS; PBCH; PSS and SSS; PSS and PBCH; SSS and PBCH.

[0244] In one example, the first SSB may be a dedicated signal, that is, used only to indicate the transmission status of an on-demand signal.

[0245] For example, the first SSB may be a non-cell defining SS / PBCH block (NCD-SSB). The NCD-SSB may be an SSB not associated with CORESET#0, such as the last SSB in a burst set.

[0246] Exemplarily, the first SSB may be a cell defining SS / PBCH block (CD-SSB).

[0247] The above description is merely exemplary, and any first signal used to determine whether the transmission status of an on-demand signal has changed or to indicate the changed transmission status of an on-demand signal should fall within the scope of protection of the present disclosure.

[0248] In some embodiments, the first signal may be used to indicate at least one of the following:

[0249] ceasing transmission of one or more of said on-demand signals;

[0251] An Acknowledgement (ACK) message is used to respond to a request message and confirm transmission of one or more of the on-demand signals, and the request message is used to request transmission of one or more of the on-demand signals.

[0252] The on-demand signal includes at least one of the second SSB, system message, and RACH.

[0262] The seventh ACK message, the seventh confirmation message is used to respond to the seventh request message and confirm the transmission of the second SSB, system message and RACH, and the seventh request message is used to request the transmission of the second SSB, system message and RACH.

[0263] The above description is merely an exemplary description, and all contents related to the transmission status of the on-demand signal indicated by the first signal should fall within the protection scope of the present disclosure.

[0264] In some embodiments, the network device 102 may determine the resource location of the first signal based on a predefined method, where the predefined method may be a method agreed upon in a protocol.

[0265] In one example, the network device 102 may determine the time domain parameters and the frequency domain parameters of the first signal based on a predefined manner.

[0266] Exemplarily, the time domain parameters may include but are not limited to at least one of the following: cycle duration; time unit; time unit offset.

[0267] The time unit may be a frame, a time slot, a symbol, a duration (span), etc., which is not limited in the present disclosure. A span includes one or more consecutive symbols within a time slot.

[0268] The time unit offset may be an offset of a start time unit of the first signal relative to a start time unit of the cycle.

[0269] Exemplarily, the frequency domain parameters may include but are not limited to at least one of the following: a starting RB; the number of occupied RBs; and a signal pattern.

[0270] In some embodiments, the network device 102 may configure the resource location of the first signal for the terminal 101 .

[0271] In an example, the network device 102 may configure the time domain parameters and frequency domain parameters of the first signal for the terminal 101 .

[0272] Exemplarily, the time domain parameters may include but are not limited to at least one of the following: cycle duration; time unit; time unit offset.

[0273] Exemplarily, the frequency domain parameters may include but are not limited to at least one of the following: a starting RB; the number of occupied RBs; and a signal pattern.

[0274] Exemplarily, the network device 102 may configure at least one of a time domain parameter and a frequency domain parameter of the first signal for the terminal 101 through a first radio resource control (RRC) signaling.

[0275] Exemplarily, the network device may configure the time-frequency domain resources of the first signal for the terminal 101 based on at least one of the following configurations:

[0276] Downlink carrier bandwidth (carrierBandwidthDL);

[0277] Downlink carrier frequency (carrierFreqDL);

[0278] Multicast / multicast single frequency network subframe configuration list (mbsfn-SubframeConfigList).

[0279] Frequency domain position;

[0280] Time domain position.

[0281] In some embodiments, the network device 102 may configure the resource location of the first signal based on a predefined method and the first RRC signaling.

[0282] In one example, the network device 102 may determine multiple patterns of the first signal based on a defined manner. Further, the network device 102 may configure the first pattern used by the first signal through a first RRC signaling. The first pattern may be one of the multiple patterns described above.

[0283] In some embodiments, the network device 102 may determine the sequence of the first signal based on a predefined manner.

[0284] Exemplarily, the first signal corresponds to multiple sequences, and the network device 102 may determine a sequence corresponding to the first signal from the multiple sequences based on a predefined method.

[0285] In some embodiments, the network device 102 may configure the sequence of the first signal through a second RRC signaling. The second RRC signaling and the first RRC signaling may be the same or different RRC signaling, which is not limited in this disclosure.

[0286] Exemplarily, the network device 102 may configure the sequence of the first signal by using at least one of the following configuration parameters:

[0287] Number of CRS antenna ports, such as nrofCRS-Ports;

[0288] CRS Resource Element (RE) offset, such as v-Shift;

[0289] Timing extraction offset TA-offset;

[0290] Cell ID;

[0291] Sequence initial value c init .

[0292] In some embodiments, the network device 102 may first determine multiple sequences corresponding to the first signal based on a predefined method, and then configure a sequence of the first signal through the second RRC signaling.

[0293] In some embodiments, compatibility of the first signal with legacy solutions also needs to be considered.

[0294] In one example, when the first signal is CRS, the terminal can determine the time-frequency domain resources of CRS and the corresponding CRS sequence based on the configuration. The network device 102 can send the CRS to the terminal 101 in the NR system. At this time, the CRS is used to indicate that the transmission status of the on-demand signal has changed.

[0295] In one example, the first signal is a simplified SSB. If the network device 102 sends the simplified SSB to the terminal 101, the simplified SSB is used to indicate that the transmission status of the on-demand signal has changed.

[0296] In one example, the first signal is a first SSB, which is a dedicated SSB. The network device 102 can send the first SSB to the terminal 101, and the first SSB is only used to indicate that the transmission status of the on-demand signal has changed.

[0297] In one example, when the first signal is a CSI-RS, the network device 102 can distinguish it from the legacy solution in the following manner:

[0298] In the first manner, the network device 102 configures at least one of the number of time units occupied by the CSI-RS, the number of RBs, and the first pattern used based on predefined configurations.

[0299] Exemplarily, the network device 102 may configure the number of time units occupied by the CSI-RS to be equal to the first value.

[0300] Exemplarily, the network device 102 may configure the number of RBs occupied by the CSI-RS to be equal to the second value.

[0301] For example, the network device 102 may configure the first pattern used by the CSI-RS to be one of the designated patterns.

[0302] Exemplarily, the network device 102 may configure the number of time units occupied by the CSI-RS to be equal to the first value, and / or configure the number of RBs occupied by the CSI-RS to be equal to the second value, and / or configure the first pattern used by the CSI-RS to be one of the specified patterns.

[0303] In the second manner, the network device 102 sends instruction information to the terminal 101 .

[0304] The indication information is used to indicate that the CSI-RS is used to indicate that the transmission state of the on-demand signal has changed.

[0305] Step S2103: Terminal 101 determines the resource location of the first signal.

[0306] In some embodiments, the terminal 101 may determine the resource location of the first signal based on a predefined method.

[0307] In some embodiments, the terminal 101 may determine the resource location of the first signal based on the configuration of the network device 102 .

[0308] In some embodiments, the terminal 101 may determine the resource location of the first signal based on a predefined method and the configuration of the network device 102 .

[0309] The method for determining the resource location is similar to the method in which the network device 102 determines the resource location in step S2102, and will not be repeated here.

[0310] In some embodiments, the terminal 101 may also determine a specific sequence corresponding to the first signal in a manner similar to that in which the network device 102 determines the sequence corresponding to the first signal, which will not be described in detail here.

[0311] Step S2104 , the network device 102 sends a first signal to the terminal 101 .

[0312] In some embodiments, when network device 102 determines to stop transmitting one or more of the on-demand signals, it may send a first signal to terminal 101 .

[0313] In some embodiments, when the network device 102 determines to transmit one or more of the on-demand signals, it may send a first signal to the terminal 101 .

[0314] In some embodiments, the network device 102 receives a request message sent by the terminal 101, where the request message is used to request transmission of one or more on-demand signals. Further, the network device 102 sends a first signal to the terminal 101 based on the request message.

[0315] In one example, the request message may reuse a wake-up signal (WUS). The network device 102 sends a first signal to the terminal 101 based on the received WUS.

[0316] In some embodiments, the network device 102 may send a first signal to the terminal 101 at the determined resource location.

[0317] In some embodiments, terminal 101 attempts to receive the first signal at the resource location.

[0318] In some embodiments, terminal 101 attempts to receive a first signal within a first time window.

[0319] In some embodiments, the terminal 101 may determine the starting time unit of the first time window in any of the following ways:

[0320] In one example, the terminal 101 determines the time unit in which the first RRC signaling is located as the starting time unit of the first time window.

[0321] In one example, the terminal 101 determines the starting time unit of the current SSB cycle configured by the first RRC signaling as the starting time unit of the first time window.

[0322] In one example, the terminal 101 determines the starting time unit of the current SIB1 cycle configured by the first RRC signaling as the starting time unit of the first time window.

[0323] The first RRC signaling is an RRC signaling for configuring a resource location where the first signal is located.

[0324] In one example, the terminal 101 determines the starting time unit of the next SSB period configured by the first RRC signaling as the starting time unit of the first time window.

[0325] In an example, the terminal 101 determines the starting time unit of the next SIB1 cycle configured by the first RRC signaling as the starting time unit of the first time window.

[0326] In an example, the terminal 101 determines the starting time unit of the DCI period corresponding to the next blind detection SIB1 configured by the first RRC signaling as the starting time unit of the first time window.

[0327] The first RRC signaling is an RRC signaling for configuring a resource location where the first signal is located.

[0328] In an example, the terminal 101 determines the period start time unit of the next first type common search space (CSS) where the first RRC signaling is located as the start time unit of the first time window. The first type may be type 0.

[0329] In addition, the terminal 101 may determine the size of the first time window in any of the following ways:

[0330] In one example, the terminal 101 may determine P1 SSB periods as the size of the first time window, where P1 is a positive integer. Each SSB period may be configured based on RRC signaling (first RRC signaling) sent by the network device, or may be a default period, such as 20 milliseconds.

[0331] In one example, the terminal 101 may determine the blind detection period corresponding to P2 first-type CSSs as the size of the first time window, where P2 is a positive integer. Each blind detection period may be configured based on RRC signaling (first RRC signaling) sent by the network device, or may be a default period, for example, 20 milliseconds.

[0332] In one example, the terminal 101 may determine P3 consecutive time units as the size of the first time window, where P3 is a positive integer. The time unit may be a frame, slot, symbol, subframe, span, etc., which is not limited in this disclosure.

[0333] The above description is merely exemplary, and the present disclosure does not limit the method by which the terminal 101 determines the first time window.

[0334] Step S2105 : In response to successfully receiving the first signal, the terminal 101 determines, based on the first signal, that the transmission state of the on-demand signal has changed.

[0335] In some embodiments, the first signal is CRS. Since CRS is a signal in the LTE system, if the terminal 101 receives CRS in the NR system, the terminal 101 can directly determine that CRS is used to indicate a change in the transmission status of the on-demand signal.

[0336] In some embodiments, the first signal is a simplified SSB, and the terminal 101 may determine that the simplified SSB is used to indicate a change in the transmission state of the on-demand signal.

[0337] In some embodiments, the first signal is a first SSB, and the terminal 101 may determine that the first SSB is used to indicate a change in the transmission state of the on-demand signal.

[0338] In some embodiments, when the first signal is a CSI-RS, such as a TRS, the terminal 101 may use any of the following methods to determine whether the CSI-RS is used to indicate a change in the transmission state of the on-demand signal:

[0339] The first way is to determine based on a predefined way that the CSI-RS indicates that the transmission state of the on-demand signal has changed.

[0340] In one example, if the terminal 101 determines that the number of time units occupied by the CSI-RS is equal to the first value, and / or the number of RBs occupied by the CSI-RS is equal to the second value, and / or the first pattern used by the CSI-RS is one of the specified patterns, then the terminal 101 can determine that the CSI-RS is used to indicate a change in the transmission status of the on-demand signal.

[0341] In the second manner, the terminal 101 determines, based on the indication information sent by the network device, a CSI-RS for indicating a change in the transmission state of the on-demand signal.

[0342] In one example, the network device 102 sends the indication information to explicitly indicate that the CSI-RS is used to indicate a change in the transmission state of the on-demand signal.

[0343] In some embodiments, exemplarily, the CSI-RS is a TRS, the TRS is a TRS configured by the secondary cell activation configuration (SCellActivationRS-Config), and when the corresponding medium access control unit (Medium Access Control Element, MAC CE) enhanced secondary cell activation / deactivation (Enhanced Scell ​​Activation / Deactivation) indicates that the TRS configured by the SCellActivationRS-Config is in an activated state, the terminal 101 determines that the network device 102 continues to transmit one or more of the on-demand signals.

[0344] Exemplarily, when the TRS is the TRS configured by SCellActivationRS-Config, and the corresponding MAC CE Enhanced Scell ​​Activation / Deactivation indicates that the TRS configured by SCellActivationRS-Config is in a deactivated state, the terminal 101 determines that the transmission state of the on-demand signal has changed. At this time, the terminal 101 determines that the network device 102 stops transmitting one or more of the on-demand signals.

[0345] Exemplarily, the transmission status of the on-demand signal is determined based on a MAC CE indication.

[0346] Exemplarily, if the corresponding MAC CE Enhanced Scell ​​Activation / Deactivation indicates that the SCell is in active state, the terminal 101 determines that the transmission state of the on-demand signal has changed. At this time, the terminal 101 determines that the network device 102 continues to transmit one or more of the on-demand signals.

[0347] Exemplarily, if the corresponding MAC CE Enhanced Scell ​​Activation / Deactivation indicates that the SCell is in the deactive state, the terminal 101 determines that the transmission state of the on-demand signal has changed. At this time, the terminal 101 determines that the network device 102 stops transmitting one or more of the on-demand signals.

[0348] The above is merely an example, and the terminal 101 may determine the CSI-RS to indicate a change in the transmission state of the on-demand signal based on other methods.

[0349] In step S2106, the network device 102 performs corresponding operations.

[0350] In some embodiments, the first signal is used to indicate that the transmission of one or more of the on-demand signals is abandoned, and the network device 102 no longer sends and / or no longer receives one or more of the on-demand signals.

[0373] In step S2201 , the network device 102 determines that the transmission state of the on-demand signal needs to be changed.

[0374] The implementation method is similar to the above step S2101 and will not be repeated here.

[0375] In step S2202, the network device 102 performs corresponding operations.

[0376] In some embodiments, the network device 102 stops sending and / or stops receiving one or more of the on-demand signals.

[0377] In some embodiments, the network device 102 begins sending and / or begins receiving one or more of the on-demand signals.

[0378] In step S2203, the terminal 101 determines, based on a predefined method, that the transmission state of the on-demand signal has changed.

[0379] In some embodiments, if terminal 101 fails to receive at least one of the second SSB and the system message sent by network device 102 for N consecutive periods, terminal 101 determines that the transmission state of the on-demand signal has changed, where N is a positive integer.

[0380] In some embodiments, if the terminal 101 does not receive the message 2 sent by the network device 102 after sending M RACHs continuously, the terminal 101 determines that the transmission state of the on-demand signal has changed.

[0381] In some embodiments, in response to reaching a start time point and / or an end time point of the first time period, terminal 101 determines that the transmission state of the on-demand signal changes.

[0382] For example, the first time period may be a time period preconfigured by network device 102 for stopping transmission of the on-demand signal. Assuming the first time period is 0:00-4:00, terminal 101 determines at 0:00 every day that the transmission state of the on-demand signal has changed, and the transmission state of the on-demand signal after the change is stopped. At 4:00 every day, terminal 101 determines that the transmission state of the on-demand signal has changed, and the transmission state of the on-demand signal after the change is transmitted.

[0383] In some embodiments, in response to reaching a start time point and / or an end time point of the second time period, terminal 101 determines that the transmission state of the on-demand signal has changed.

[0384] For example, the second time period may be a time period preconfigured by network device 102 for transmitting an on-demand signal. Assuming the second time period is 4:00-24:00, terminal 101 determines at 4:00 every day that the transmission state of the on-demand signal has changed, and the changed transmission state of the on-demand signal is transmitting. At 24:00 every day, terminal 101 determines that the transmission state of the on-demand signal has changed, and the changed transmission state of the on-demand signal is stopped.

[0388] In some embodiments, step S2201 is optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, when the network device 102 determines that the transmission state of the on-demand signal does not need to be changed, step S2101 may not be performed.

[0389] In some embodiments, step S2203 is optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, when terminal 101 determines based on the first signal that the transmission state of the on-demand signal has changed, step S2203 may not be performed.

[0433] In the above embodiment, the energy consumption of the network device is reduced, the availability of network energy saving is improved, and it can be ensured that the terminal and the network device have the same understanding of the transmission status of the on-demand signal.

[0434] The above process is further illustrated by the following examples:

[0435] Terminal side:

[0436] A terminal supporting network energy-saving technology determines the transmission status of the corresponding on-demand signal by receiving the following reference signals:

[0437] Solution 1: The terminal receives the CRS and determines the transmission status of the on-demand signal.

[0438] In one example, the terminal determines the time-frequency domain resources for receiving the CRS based on signaling configuration or a predefined method:

[0439] Exemplarily, the time domain parameters include: a period, a time unit (eg, a frame, a time slot, a symbol, etc.), and a time unit offset.

[0440] Exemplarily, the frequency domain parameters include: starting RB, number of occupied RBs, signal pattern, etc.

[0441] Exemplarily, the terminal determines the time-frequency domain resources based on the existing configuration: carrierBandwidthDL, carrierFreqDL, mbsfn-SubframeConfigList.

[0442] Exemplarily, the terminal determines multiple patterns corresponding to the CRS based on a predefined method, and determines one of the multiple patterns through the received first RRC signaling.

[0443] In one example, the terminal determines a sequence for receiving CRS based on signaling configuration or a predefined method.

[0444] Exemplarily, the terminal determines the sequence of the CRS based on the following configuration parameters: nrofCRS-Ports, v-Shift, TA-offset, LTE Cell ID, sequence initial value cinit, etc.

[0445] Exemplarily, the terminal determines multiple patterns corresponding to the CRS based on a predefined method, determines one of the multiple patterns by receiving signaling, and then determines the sequence corresponding to the CRS based on the pattern corresponding to the CRS.

[0446] The terminal attempts to receive the corresponding CRS sequence based on the above time-frequency domain resources. If the above CRS sequence is successfully received, the terminal determines the transmission status of the corresponding on-demand signal.

[0447] Solution 2: The terminal receives a simplified SSB signal and determines the transmission status of the ondemand signal.

[0448] In one example, the terminal determines the time-frequency domain resources for receiving the simplified SSB based on signaling configuration or a predefined method.

[0449] Exemplarily, the time domain parameters include: a period, a time unit (eg, a frame, a time slot, a symbol, etc.), and a time unit offset.

[0450] Exemplarily, the frequency domain parameters include: starting RB, number of occupied RBs, signal pattern, etc.

[0451] In one example, the terminal determines a sequence for receiving simplified SSBs based on a signaling configuration or a predefined manner.

[0452] The simplified SSB is one or two of the PSS signal, SSS signal, and PBCH corresponding to the SSB of this cell;

[0453] The terminal attempts to receive the corresponding simplified SSB sequence based on the time-frequency domain resources. If the simplified SSB sequence is successfully received, the terminal determines the transmission status of the corresponding on-demand signal.

[0454] Solution 3: The terminal receives a specific SSB (the first SSB) and determines the transmission status of the on-demand signal.

[0455] In one example, the terminal determines the time-frequency domain resources for receiving SSB based on signaling configuration or a predefined method.

[0456] Exemplarily, the SSB is an NCD-SSB, for example, an SSB not associated with CORESET#0, or the last SSB in a burst.

[0457] Exemplarily, the terminal determines that the first SSB is only used to indicate the transmission status of the on demand signal.

[0458] The terminal attempts to receive the corresponding first SSB sequence based on the above-mentioned time-frequency domain resources. Under the condition of successfully receiving the above-mentioned first SSB sequence, the terminal determines the transmission status of the corresponding on-demand signal.

[0459] Solution 4: The terminal receives CSI-RS (eg, TRS) and determines the transmission status of the on-demand signal.

[0460] In one example, the terminal determines the time-frequency domain resources for receiving TRS / CSI-RS based on signaling configuration or a predefined method.

[0461] Exemplarily, the time domain parameters include: a period, a time unit (eg, a frame, a time slot, a symbol, etc.), and a time unit offset.

[0462] Exemplarily, the frequency domain parameters include: starting RB, number of occupied RBs, signal pattern, etc.

[0463] Exemplarily, the number of RBs occupied by the TRS is equal to the second value, and the second value is 24.

[0464] The terminal attempts to receive the corresponding TRS / CSI-RS signal based on the above time-frequency domain resources. Under the condition of successfully receiving the above TRS / CSI-RS sequence, the terminal determines the transmission status of the corresponding on-demand signal.

[0465] Exemplarily, the TRS is a TRS used for cell activation / de-activation.

[0466] Exemplarily, the TRS is based on the TRS configured by SCellActivationRS-Config.

[0467] Exemplarily, when the TRS is a TRS configured by SCellActivationRS-Config and the corresponding MAC CE Enhanced Scell ​​Activation / Deactivation indicates that the TRS configured by SCellActivationRS-Config is in an activated state, the terminal determines that the network device continues to transmit SSB / SIB1.

[0468] Exemplarily, when the TRS is a TRS configured by SCellActivationRS-Config, and the corresponding MAC CE Enhanced Scell ​​Activation / Deactivation indicates that the TRS configured by SCellActivationRS-Config is in a deactivated state, the terminal determines that the network device stops transmitting SSB / SIB1.

[0469] Exemplarily, the transmission status of the on-demand signal is determined based on a MAC CE indication.

[0470] Exemplarily, if the corresponding MAC CE Enhanced Scell ​​Activation / Deactivation indicates that the SCell is in the active state, the terminal determines that the network side continues to transmit SSB / SIB1.

[0471] Exemplarily, if the corresponding MAC CE Enhanced Scell ​​Activation / Deactivation indicates that the SCell is in a deactive state, the terminal determines that the network side stops transmitting SSB / SIB1.

[0481] Exemplarily, the network device determines multiple patterns corresponding to the CRS based on a predefined method, and configures one of the multiple patterns through RRC signaling.

[0482] The network device sends a corresponding CRS sequence based on the above time-frequency domain resources to indicate that the transmission state of the on-demand signal has changed.

[0483] Exemplarily, when the network device is in the state of sending SIB1 / SSB, it indicates the state switching of SIB1 / SSB by sending a CRS sequence, that is, stopping sending SIB1 / SSB.

[0484] Exemplarily, when the network device stops sending SIB1 / SSB, it indicates the state switching of SIB1 / SSB by sending a CRS sequence, that is, sending SIB1 / SSB.

[0494] Exemplarily, the SSB is NCD-SSB, which corresponds to the last SSB in the burst.

[0495] Exemplarily, the network device determines that the first SSB is only used for an indication of the transmission status of an on-demand signal.

[0498] Exemplarily, when the network device stops sending SIB1 / SSB, it indicates the state switching of SIB1 / SSB by sending an SSB sequence, that is, sending SIB1 / SSB.

[0499] Solution 4: The network device sends a TRS / CSI-RS signal to indicate the transmission status of the on-demand signal. In one example, the network device determines the time-frequency domain resources for sending the TRS / CSI-RS based on signaling configuration or a predefined method:

[0512] Exemplarily, if the corresponding MAC CE Enhanced Scell ​​Activation / Deactivation indicates that the SCell is in a deactive state, the network device stops transmitting SSB / SIB1.

[0513] The following will describe the specific implementation of the present invention from the perspective of network devices and terminals.

[0514] Assume that the terminal is a Rel-18 or later version terminal, the terminal is a terminal that supports the Network Energy Saving (NES) feature, and the network device is a network device that supports network energy saving technology. To support the demand for network energy saving, considering that the network device may give up sending corresponding system information, such as SSB / SIB1 / SIBn, or give up receiving corresponding uplink signals, such as RACH, within a certain period of time, the terminal needs to give up receiving the system information or transmitting the uplink signal based on the corresponding network-side behavior.

[0515] If a network device abandons sending a corresponding signal within a certain period of time, the information can be called an on-demand signal. The present invention uses SSB and SIB1 as examples to illustrate the embodiment of the present invention. Other information is also within the scope of protection of the present invention and will not be described in detail here.

[0516] The transmission status indication of the on-demand SSB / SIB involved in the solution of the present invention includes at least one of the following:

[0517] Not transmitting SSB, and / or not transmitting SIB1;

[0518] Start transmitting SSB, and / or, start transmitting SIB1;

[0519] After the terminal sends a request message for SSB and / or SIB1 transmission, the indication signaling is used to restart transmission of the SSB and / or restart transmission of the ACK message of SIB1.

[0520] Based on the above indication status, the corresponding implementation process can be shown in Figures 4A, 4B and 4C below.

[0521] In FIG4A , the network device determines not to send SSB / SIB1 any more, and then the network device sends a first signal to the terminal, and the terminal determines not to receive SSB / SIB1 any more based on the first signal.

[0522] In FIG4B , the network device determines to send SSB / SIB1, and the network device sends a first signal to the terminal, and the terminal receives SSB / SIB1 based on the first signal.

[0523] In Figure 4C, the network device determines not to send SSB / SIB1 anymore, and the terminal sends a request message to the network device. The request message may be a wake-up signal. Based on the request message, the network device determines to send SSB / SIB1, and then sends a first signal to the terminal so that the terminal receives SSB / SIB1 based on the first signal.

[0524] It is worth noting that Figures 4A, 4B, and 4C are exemplary descriptions of the application scenarios of the solution of the present invention. Other application scenarios are also within the protection scope of the solution of the present invention, and the solution of the present invention will not be described in detail.

[0525] For the above application scenarios, the specific embodiments of the present invention are as follows:

[0526] Embodiment 1: The terminal determines the transmission status of the on-demand SSB / SIB1 based on different first signals. Exemplarily, the correspondence between the first signal and the transmission status includes any one of the following:

[0527] The first signal 1 corresponds to not transmitting SSB;

[0528] The first signal 2 corresponds to not transmitting SIB1;

[0529] The first signal 3 corresponds to not transmitting SSB and not transmitting SIB1;

[0530] The first signal 4 corresponds to transmission SSB;

[0531] The first signal 5 corresponds to the transmission SIB1;

[0532] The first signal 6 corresponds to the transmission of SSB and the non-transmission of SIB1;

[0533] The first signal 7 corresponds to the ACK message that triggers the SSB request information;

[0534] The first signal 8 corresponds to the ACK message that triggers the SIB1 request information;

[0535] The first signal 9 corresponds to the ACK message that triggers the SSB / SIB1 request information.

[0536] In embodiment 2, the terminal determines the transmission status of the on-demand SSB / SIB1 based on a predefined method and a first signal.

[0537] Exemplarily, if the terminal can periodically receive SSB based on configuration information, and / or obtain valid SIB1 information based on scheduling information, and / or the terminal can receive SSB and / or receive SIB1 within the first time window, if the terminal receives the first signal, the terminal determines that it will no longer receive the corresponding SSB and / or SIB1 information.

[0538] Exemplarily, if the terminal does not receive SSB and / or SIB1 within the first time window, or the terminal sends SSB / SIB1 request information, the terminal receives the first signal, and the terminal determines to continue receiving the corresponding SSB and / or SIB1 signal.

[0539] The first time window can be determined through signaling configuration or predefined method, and the time windows corresponding to the SSB and SIB1 can be the same or different.

[0540] The first time window is determined based on one or more of the following methods:

[0541] The first time window starts at the time when the first RRC signaling is transmitted;

[0542] The first time window starts at the start position of the next SSB cycle where the first RRC signaling is located;

[0543] The first time window starts at the start position of the next Type 0CSS period in which the first RRC signaling is located;

[0544] The length of the first time window is equal to P1 SSB periods, where the SSB period is configured based on signaling or is a default period (20 ms);

[0545] The first time window is equal to the blind detection period corresponding to P2 Type 0CSSs, and the blind detection period is based on signaling configuration or a default period (20ms);

[0546] The first time window is equal to P3 time units, and the time unit can be a frame, a time slot, a symbol, a subframe, etc.

[0547] In embodiment 3, the terminal determines, based on signaling configuration or a predefined method, a first time domain resource location and / or a first frequency domain resource location where the reference signal is received, where the location parameter specifically includes at least one of the following:

[0548] The time domain parameters include: period, time unit (such as frame, time slot, symbol, etc.), time unit offset;

[0549] The frequency domain parameters include: starting RB, number of occupied RBs, signal pattern, etc.

[0550] Taking the predefined manner as an example, the time position may be a signal transmitted in the first slot of the first frame with a period of 160 ms.

[0551] Taking the predefined manner as an example, the frequency domain position may be the lowest or highest S1 PRBs within the BWP. Exemplarily, S1=24.

[0552] Taking the predefined manner as an example, the frequency domain position may be the lowest or highest S2 PRBs within the frequency domain range occupied by the SSB. Exemplarily, S2=12.

[0553] Taking the predefined manner as an example, the frequency domain position may be the lowest or highest S3 PRBs within the frequency domain range occupied by CORESET#0. Exemplarily, S3=12.

[0554] The terminal receives a corresponding first signal based on the time-frequency domain position and determines a transmission state of the on-demand signal, where the first signal includes at least one of the following:

[0555] Example 3.1, CRS signal.

[0556] The network device sends the following configuration signaling to indicate the time-frequency domain position of the CRS and / or CRS sequence information, where the configuration information includes one or more of the following:

[0557] The number of PRBs occupied by CRS, such as carrierFreqDL;

[0558] The center frequency of the carrier where the CRS is located, such as carrierBandwidthDL;

[0559] MBSFN subframe configuration, such as mbsfn-SubframeConfigList;

[0560] Number of CRS ports, for example, nrofCRS-Ports;

[0561] RE offset, such as v-shift;

[0562] cell ID, such as cell-ID;

[0563] Pseudo-random sequence initial parameter cint;

[0564] CP information, such as Normal Cyclic Prefix (NCP) and Extended Cyclic Prefix (ECP).

[0565] The terminal receives the above configuration information, and refers to the CRS mechanism to determine the CRS transmission time-frequency domain pattern and / or CRS sequence, and receives the corresponding CRS at the first time domain position and / or the first frequency domain position.

[0566] Example 3.1.1, a possible implementation method, the terminal determines the CRS transmission time-frequency domain pattern based on existing RRC signaling, such as RateMatchPatternLTE-CRS. Considering that the terminal cannot obtain CRS sequence information, the terminal blindly detects the corresponding CRS at the first time domain position and / or the first frequency domain position, or detects the received signal strength indication (RSSI). When the RSSI exceeds a certain threshold, it determines that the corresponding CRS sequence is received. The possible CRS pattern is shown in Figure 4D.

[0567] Example 3.1.2: In a possible implementation, a network device sends configuration information to indicate a first time domain position and / or a first frequency domain position at which a CRS may be transmitted. If the network device determines to switch to the on-demand SSB / SIB1 state, the network device sends a CRS signal to indicate the corresponding state switch. Based on the configuration information, the terminal receives and attempts to receive the corresponding CRS at the first time domain position and / or the first frequency domain position. If the CRS is successfully received, the terminal determines that the on-demand SSB / SIB1 state has been switched.

[0568] The network device sends the corresponding CRS sequence based on the above time-frequency domain resources to indicate the switching of the on-demand signal state:

[0569] Exemplarily, when the network device is in the state of sending SIB1 / SSB, it indicates the state switching of SIB1 / SSB by sending a CRS sequence, that is, stopping sending SIB1 / SSB.

[0570] Exemplarily, when the network device stops sending SIB1 / SSB, it indicates the state switching of SIB1 / SSB by sending a CRS sequence, that is, sending SIB1 / SSB.

[0571] The terminal attempts to receive the corresponding CRS sequence based on the above time-frequency domain resources. If the above CRS sequence is successfully received, the terminal determines the transmission status of the corresponding on-demand signal.

[0572] Example 3.2: simplified SSB or SSB signal.

[0573] In embodiment 3.2.1, the simplified SSB may be a PSS signal or an SSS signal, which is transmitted based on the SSB pattern. That is, the PSS is transmitted on the first symbol corresponding to the SSB, occupying 127 resource elements (REs). Alternatively, the SSS is transmitted on the third symbol corresponding to the SSB, occupying 127 REs. The relative position of the corresponding PSS or SSS in the SSB is shown, for example, in FIG4E .

[0574] In embodiment 3.2.2, the simplified SSB may be a PSS signal and an SSS signal. The PSS signal and the SSS information occupy 127 REs. The PSS is transmitted on the first symbol corresponding to the SSB, occupying 127 REs; the SSS is transmitted on the second symbol corresponding to the SSB, occupying 127 REs.

[0575] In embodiment 3.2.3, the simplified SSB may be PBCH and PSS, or PBCH and SSS. If the PBCH is used to indicate the transmission status of an on-demand signal, the network device may refarm the corresponding MIB to indicate the transmission status of the on-demand signal. The indication information may include one or more of the following:

[0576] Corresponding SSB transmission status indication information: illustratively, no longer transmitting the corresponding SSB, or continuing to transmit the corresponding SSB;

[0577] Corresponding SIB1 transmission status indication information: illustratively, no longer transmitting the corresponding SIB1, or continuing to transmit the corresponding SIB1;

[0578] Indication of the starting position (offset) of the validation window corresponding to the transmission state. Exemplarily, the terminal determines the starting position of the corresponding time window based on the time unit in which the DCI is received and the offset indication. The offset is based on the granularity of a time unit, such as a frame, subframe, slot, symbol, SSB period, Type 0 CSS blind detection period, etc.

[0579] Indicative information of the time length of the corresponding transmission state; illustratively, the time length is based on the granularity of time units, and the time units are based on the above definition and will not be repeated here.

[0580] The indication information of the cell / BWP / SSB index / beam corresponding to the transmission state is effective. For example, the information field can be used for one or more cells, BWP, SSB index and beam, etc. to which the DCI indication information is applied.

[0581] In embodiment 3.2.4, the first signal may be the first SSB transmitted at the first time domain position or the first frequency domain position. Exemplarily, the first SSB may be an SSB that is not associated with CORESET#0. Exemplarily, the first SSB is only used to indicate the transmission status of the on-demand signal. In this scenario, the information unit in the MIB corresponding to the first SSB (e.g., pdcch-ConfigSIB1) can be used to indicate the transmission status of the on-demand signal. For specific indication parameters, see embodiment 3.2.3.

[0582] Example 3.2.5, a possible implementation method, the network device sends configuration information to indicate the first time domain position and / or the first frequency domain position where the simplified SSB or the first SSB may be transmitted. Or, based on a predefined method, the first time domain position and / or the first frequency domain position is determined. Exemplarily, the time domain position is the first or last SSB that can be transmitted in the SSB burst with a period of 160ms, and the SSB is not associated with CORESET#0, for example, for FR1, the subcarrier offset is >23, and for FR2, the subcarrier offset is >11. The network device sends the corresponding simplified SSB sequence or the first SSB sequence based on the above-mentioned time-frequency domain resources to indicate that the transmission status of the on-demand signal has changed.

[0583] Exemplarily, when the network device is in the state of sending SIB1 / SSB, it indicates the state switching of SIB1 / SSB by sending a simplified SSB sequence or a first SSB sequence, that is, stops sending SIB1 / SSB.

[0584] Exemplarily, when the network device stops sending SIB1 / SSB, it indicates the state switching of SIB1 / SSB by sending a simplified SSB sequence or a first SSB sequence, that is, sending SIB1 / SSB.

[0585] The terminal attempts to receive the corresponding simplified SSB sequence or the first SSB sequence based on the above-mentioned time-frequency domain resources. Upon successfully receiving the above-mentioned simplified SSB sequence or the first SSB sequence, the terminal determines that the transmission state of the corresponding on-demand signal has changed.

[0586] Embodiment 3.3: TRS or CSI-RS signal.

[0587] Example 3.3.1, the first signal can be a periodic (P) TRS signal or an aperiodic-persistent (AP) TRS signal. The TRS signal can be determined based on a predefined method, for example, a TRS signal occupying 24 RBs, and / or a TRS signal transmitted at a first time domain position and / or a first frequency domain position.

[0588] In embodiment 3.3.2, the signal may be a P, AP or semi-persistent (SP) non-zero power channel state information reference signal (Non zero power CSI-RS, NZP CSI-RS), and the NZP CSI-RS signal may be determined based on a predefined method, for example, an NZP CSI-RS signal occupying 24 RBs, and / or a TRS signal transmitted at a first time domain position and / or a first frequency domain position.

[0589] In one possible implementation, the network device sends configuration information indicating a first time domain position and / or a first frequency domain position where a CSI-RS may be transmitted, or determines the first time domain position and / or the first frequency domain position based on a predefined method.

[0590] The network device sends the corresponding CSI-RS sequence based on the above time-frequency domain resources to indicate that the transmission state of the on-demand signal has changed:

[0591] Exemplarily, when the network device is sending SIB1 / SSB, it sends a TRS / CSI-RS sequence to indicate that the transmission state of SIB1 / SSB has changed, that is, to stop sending SIB1 / SSB.

[0592] Exemplarily, when the network device stops sending SIB1 / SSB, it sends a TRS / CSI-RS sequence to indicate that the transmission state of SIB1 / SSB has changed, that is, sends SIB1 / SSB.

[0593] The terminal determines the time-frequency domain resources and / or TRS / CSI-RS signal sequence as a transmission status indication signal for an on-demand signal. The terminal attempts to receive the corresponding TRS / CSI-RS sequence based on the time-frequency domain resources. Upon successful reception of the TRS / CSI-RS sequence, the terminal determines the transmission status of the corresponding on-demand signal.

[0594] The embodiment of the present invention mainly designs a related reference signal to indicate the transmission status of an on-demand signal, which is beneficial for achieving network energy saving while ensuring consistent understanding between network devices and terminals.
