The term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone.

[0060] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between two items, or an association relationship between the two items, or a relationship between indication and being indicated, configuration and being configured, and the like.

[0061] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application.

[0062] The DRX mechanism includes configuring a DRX cycle for a UE in the Radio Resource Control (RRC) CONNECTED state. A DRX cycle includes "On Duration" and "Opportunity for DRX". During the "On Duration" time, the UE monitors and receives downlink channels and signals including the Physical Downlink Control Channel (PDCCH). During the "Opportunity for DRX" time, the UE does not receive downlink channels and signals such as PDCCH to reduce power consumption. A UE in the RRC Idle (IDLE) state needs to receive paging messages in a similar manner to DRX. There is a paging opportunity (PO) within a DRX cycle. The UE only receives paging messages during the PO, and does not receive paging messages during times other than the PO, to achieve power saving. During the PO period, the UE determines whether there is a paging message by detecting the PDCCH signal scrambled by the P-RNTI (Paging-Radio Network Temporary Identity).

[0063] In the evolution of 5G, higher requirements are put forward for UE power saving. For example, for the DRX mechanism, during each OnDuration period, the UE needs to continuously detect the PDCCH to determine whether the base station schedules data transmission to itself. However, for most UEs, there may be no need to receive data transmission for a long time, but it is still necessary to maintain a regular wake-up mechanism to monitor possible downlink transmission. For such UEs, there is room for further optimization of power saving. The situation of UEs receiving paging messages in the RRC IDLE state is similar.

[0064] In order to further achieve energy saving, an energy saving signal is introduced. The energy saving signal is used in conjunction with the DRX mechanism, and the terminal receives an indication of the energy saving signal before the DRX On Duration. Exemplarily, the energy saving signal can also be called an energy saving wake-up signal. When the terminal has data transmission in a DRX cycle, the energy saving signal "wakes up" the terminal to monitor the PDCCH during the DRX On duration. Otherwise, when the terminal has no data transmission in a DRX cycle, the energy saving signal does not "wake up" the terminal, and the terminal does not need to monitor the PDCCH during the DRX On Duration. Compared with a single DRX mechanism, when the terminal has no data transmission, the terminal can omit PDCCH monitoring during the DRX On duration, thereby achieving energy saving. The time of the terminal outside the DRX On duration is called the inactive time, and the time during the DRX On Duration is called the active time. The process of indicating whether the terminal monitors the PDCCH during the DRX On Duration through the energy saving signal, such as Figure 2 shown.

[0065] Exemplarily, the energy-saving signal can be carried by DCI format 2_6. The network configures the terminal to detect the search space set (search space set) of the PDCCH carrying DCI format 2_6. For example, in the energy-saving signal, the number of bits required for a single user is up to 6. This includes 1 wake-up indication bit and up to 5 secondary cell sleep indication bits. The energy-saving signal carries indication bits for multiple users to improve resource utilization efficiency. Figure 3 As shown, the energy-saving signal can carry multi-user energy-saving indication information. The network notifies each user of the starting position of the energy-saving indication bit in the DCI, and the number of bits for a single user can be implicitly obtained through the number of configured secondary cell (carrier) groups (the wake-up indication bit must appear, and the number of secondary cell (carrier) sleep indication bits can be 0). Furthermore, the network will also notify the terminal of the total number of DCI bits and the PS (Power Saving, energy-saving signal)-RNTI of the scrambled PDCCH.

[0066] There is a certain timing relationship between the monitoring timing of the PDCCH and the time window of the DRX On Duration (DRX ON for short). The network configures a time offset (such as PS-offset) to determine the starting point of the PDCCH monitoring timing. After determining the starting point of the PDCCH monitoring timing, it is necessary to further determine the end point of the PDCCH monitoring. The end point of the PDCCH monitoring can be determined by the device capability of the terminal. The terminal needs to perform operations such as device wake-up and initialization after wake-up within the minimum time interval before DRX ON. Therefore, the terminal does not need to monitor the energy-saving signal within the minimum time interval before DRX ON. Terminals with faster processing speeds can use a shorter minimum time interval, see value 1 in Table 1 below, while terminals with slower processing speeds need to use a longer minimum time interval, see value 2 in Table 1.

[0067] Table 1 Minimum time interval

[0068]

[0069] The energy-saving signal starts at the time position indicated by the PS-offset configured by the network, and monitors the energy-saving signal within a complete PDCCH search space period after the starting point (for example, defined by the parameter "duration" of the PDCCH search space), and the location of the monitored energy-saving signal is before the time period corresponding to the minimum time interval. Figure 4 As shown, the terminal monitors the energy-saving signal indicated by the dotted box at a monitoring time.

[0070] In the NR system, the network can send paging to UEs in the IDLE state and the RRC-CONNECTION state. The paging process can be triggered by the core network or the base station, and is used to send a paging request to the UE in the idle state, or to notify the system information update, or to notify the UE to receive information such as Earthquake and Tsunami Warning System (ETWS) and Commercial Mobile Alert System (CMAS). After receiving the paging message from the core network, the base station interprets the content, obtains the Tracking Area Identity (TAI) list of the UE, and performs air interface paging on the cells belonging to the tracking area in the list. The core network domain of the paging message will not be decoded in the base station, but will be transparently transmitted to the UE. After receiving the paging message from the core network, the base station aggregates the paging messages of the UEs with the same PO (paging occasion) into one paging message and transmits it to the relevant UEs through the paging channel. The UE receives paging parameters through system messages, calculates PO based on its own UE_ID, and receives paging messages at the corresponding time. Paging messages are carried by the Physical Downlink Shared Channel (PDSCH). The UE obtains paging indication information by detecting the PDCCH scrambled with P-RNTI, thereby receiving paging messages. UEs in idle state save power through DRX, and the UE obtains DRX-related information from SIB2 (System Information Blocks 2). The UE listens to the PO on the PF (Paging Frame) in a DRX cycle and receives paging messages through the PDCCH scrambled with P-RNTI.

[0071] PF indicates the system frame number on which the paging message should appear, and PO indicates the possible time when it may appear. A PF frame may include one or more POs. In each DRX cycle or paging cycle, the UE only needs to monitor its own PO. A system frame number (SFN) that satisfies the following formula can be used as a PF:

[0072] (SFN+PF_offset)mod T=(T div N)*(UE_ID mod N)

[0073] In PF, the index of PO corresponding to UE_ID, ie, i_s, can be calculated according to the following formula.

[0074] i_s=floor(UE_ID / N)mod Ns

[0075] In the above formula, SFN is the system frame number, and UE_ID is the UE identifier. mod represents modulo operation, and div represents integer division operation. floor() represents rounding down. T represents the DRX cycle of the UE. If the default DRX cycle indicated in the system message is recorded as T_sib, and if the UE's DRX value T_ue has been configured, then T=min(T_ue,T_sib); if T_ue is not configured, the default value T=T_sib indicated in the system message is used. UE_ID=(5G-S-TMSI mod 1024). N is the number of PFs in T. Ns is the number of POs in a PF. PF_offset is the frame offset used to determine the PF. For example, Figure 5 As shown, the position of PF in a DRX cycle and the position of PO in PF.

[0076] The following describes NR's SS / PBCH block (SSB) transmission:

[0077] Common channels and signals in the NR system, such as synchronization signals and broadcast channels, need to cover the entire cell through multi-beam scanning to facilitate reception by UEs in the cell. Multi-beam transmission of synchronization signals (SS) is achieved by defining SS / PBCH burst sets. An SS / PBCH burst set contains one or more SS / PBCH blocks. An SS / PBCH block is used to carry the synchronization signal and broadcast channel of one beam. Therefore, an SS / PBCH burst set can contain synchronization signals of up to L beams in the cell. L is related to the frequency band of the system, for example:

[0078] For frequency range up to 3GHz, L is 4.

[0079] For frequency range from 3GHz to 6GHz, L is 8;

[0080] For frequency range from 6GHz to52.6GHz, L is 64

[0081] An SS / PBCH block (SSB) contains one symbol of the primary synchronization signal (PSS), one symbol of the SSS and two symbols of the PBCH (Physical broadcast channel). The time-frequency resources occupied by the PBCH include the demodulation reference signal (DMRS), which is used for demodulation of the PBCH.

[0082] For example, all SS / PBCH blocks in the SS / PBCH burst set are sent within a 5ms (millisecond) time window and are repeatedly sent at a certain period. The period can be configured through high-level parameters such as ssb-PeriodicityServingCell (SSB periodic service cell), and the period can include 5ms, 10ms, 20ms, 40ms, 80ms, 160ms, etc.

[0083] The current energy-saving signal needs to meet the time position indicated by the energy-saving signal offset (PS-offset) configured by the network as the starting point, and monitor the energy-saving signal within a complete PDCCH search space period after the starting point (defined by the parameter "duration" of the PDCCH search space), and the interval between the position of the monitored energy-saving signal and the starting position of the DRX On duration needs to meet the minimum time interval. This minimum time interval only needs to consider the processing capability of the UE, and does not need to consider that the UE performs time-frequency synchronization before the DRX On duration arrives, so that the PDCCH can be correctly received during the DRX On duration. This is because, for UEs in the connected state, time-frequency synchronization can be performed through the configured CSI-RS (Channel-State Information Reference Signal), TRS (Time Reference Signal) and other reference signals. For UEs in the idle state, the energy-saving signal can be used to indicate whether the UE receives paging on the reached PO. Since the idle UE is not configured with reference signals such as CSI-RS and TRS, it can only use the periodically sent (Synchronization Signal) / PBCH (Physical Broadcast Channel) block (SSB for short) for time and frequency synchronization. The current minimum time interval cannot meet the purpose of time and frequency synchronization through SSB before the arrival of PO, resulting in the inability to correctly receive paging.

[0084] Figure 6 is a schematic flow chart of a resource determination method 200 according to an embodiment of the present application. The method may optionally be applied to Figure 1 The system shown in the figure is not limited thereto. The method includes at least part of the following contents.

[0085] S210. The terminal device determines the time interval between the time domain resource of the energy-saving signal and the paging resource.

[0086] S220: The terminal device determines a time domain resource for detecting the energy-saving signal based on the time interval.

[0087] Exemplarily, the terminal device can perform time and frequency synchronization with the network through SSB before the paging resource, such as PO, arrives within the time interval between the time domain resource and the paging resource.

[0088] Optionally, in the embodiment of the present application, the paging resource includes a paging opportunity (PO) and / or a paging frame (PF). PF indicates the system frame number on which the paging message should appear, and PO indicates the possible time when the paging message may appear. Examples of PO and PF can be found in Figure 5 When the terminal device is in the RRC idle state or inactive state, it can determine the monitoring time for detecting PDCCH according to its own PF and PO, and can perform DRX at other times to achieve the purpose of saving power and energy.

[0089] Optionally, in the embodiment of the present application, the terminal device determines the time interval between the time domain resource of the energy-saving signal and the paging resource, including:

[0090] The terminal device receives configuration information, where the configuration information includes a first time interval.

[0091] Specifically, the terminal device may receive configuration information from the network device. Exemplarily, the configuration information may be configured via RRC signaling, indicated via a system message, or indicated via a DCI carried by a PDCCH.

[0092] Optionally, in the embodiment of the present application, the terminal device determines the time interval between the time domain resource of the energy-saving signal and the paging resource, further comprising:

[0093] The terminal device determines the minimum time interval between the time domain resource of the energy-saving signal and the paging resource based on the first time interval.

[0094] In an example, the terminal device may directly use the first time interval in the configuration information as the minimum time interval between the time domain resource of the energy-saving signal and the paging resource.

[0095] Optionally, in the embodiment of the present application, the terminal device determines the time interval between the time domain resource of the energy-saving signal and the paging resource, including:

[0096] The terminal device determines a second time interval based on the terminal capability;

[0097] The terminal device determines the minimum time interval between the time domain resource of the energy-saving signal and the paging resource based on the maximum value of the first time interval and the second time interval.

[0098] In one example, after receiving the configuration information, the terminal device can obtain the first time interval T1 from the configuration information, and then determine the second time interval T2 based on its own terminal capabilities, and then use the maximum value of T1 and T2 as the minimum time interval between the time domain resources of the energy-saving signal and the paging resources.

[0099] Optionally, in an embodiment of the present application, the minimum time interval between the time domain resource of the energy-saving signal and the paging resource is a predefined value. For example, the minimum time interval between the time domain resource of the energy-saving signal and the PO of the UE is a predefined value. For another example, the minimum time interval between the time domain resource of the energy-saving signal and the PF of the UE is a predefined value.

[0100] Optionally, in the embodiment of the present application, the minimum time interval is a predefined value determined based on the requirement of time-frequency synchronization recovery.

[0101] Optionally, in an embodiment of the present application, the minimum time interval is a predefined value determined based on the subcarrier spacing.

[0102] Optionally, in an embodiment of the present application, the minimum time interval between the time domain resource of the energy-saving signal and the paging resource is determined based on a predefined rule.

[0103] Optionally, in the embodiment of the present application, the predefined rule includes calculating the minimum time interval using at least one of the following parameters:

[0104] SSB transmission cycle;

[0105] Subcarrier spacing;

[0106] Terminal capabilities;

[0107] Transmission period of the reference signal.

[0108] Exemplarily, the minimum time interval can be predefined as N times the transmission period of the SSB, where N can be equal to 1, 2, 3, etc., and N can depend on the number of SSBs that the UE needs to receive to complete time-frequency synchronization recovery within the minimum time interval. If the UE obtains the transmission period T of the SSB from the system message or RRC signaling, the minimum time interval can be T*N. In addition, in combination with different subcarrier spacings, the minimum time interval can also be determined according to different rules. See Table 2.

[0109] Table 2 Minimum time interval

[0110] Subcarrier spacing (kHz) Minimum time interval (slots) 15 T*N 30 2*T*N 60 4*T*N 120 8*T*N

[0111] Exemplarily, the terminal capability may include terminal processing capability such as terminal processing time, etc. In addition, the time for the terminal to perform time-frequency recovery may also be a terminal capability.

[0132] Optionally, in an embodiment of the present application, the unit of the time interval is at least one of the following: time slot, subframe, symbol, millisecond and SSB period.

[0133] For a specific example of the network device executing the method 300 of this embodiment, reference may be made to the related description of the network device such as a base station in the above method 200, which will not be described again for the sake of brevity.

[0134] In an embodiment of the present application, a method for indicating energy-saving information for controlling paging reception is provided, and an example is as follows:

[0135] Example 1: The minimum time interval between the time domain resource of the energy saving signal and the PO or PF is configured through the network

[0136] When the UE is in RRC idle or RRC inactive state, it can determine the monitoring time of PDCCH according to its own PF and PO, and perform DRX at other times to achieve the purpose of power saving. In order to further achieve the purpose of power saving, it is ideal that the UE can know in advance whether there will be a paging message sent to itself when each of its own PO arrives. If not, the UE can not detect PDCCH in this PO to achieve further power saving.

[0137] In this example, taking the example of carrying an energy-saving signal through a sequence such as a reference signal sequence or a synchronization signal sequence, a method for determining the time domain resource location of the energy-saving signal is provided. Energy-saving information can be implicitly indicated by different sequences. The energy-saving signal can indicate whether the UE is monitoring the paging message in PF or PO. When the UE is in the RRC idle or RRC inactive state, time-frequency synchronization is required before receiving the paging message. Since the UE in the RRC idle or RRCinactive state is not configured with a UE-specific reference signal such as CSI-RS, the UE can only perform time-frequency synchronization based on SSB. Therefore, before its own PO, the UE generally needs to "wake up" in advance to start the time-frequency synchronization operation. Before the PO arrives, the UE performs time-frequency synchronization by detecting the SSB. As for how long in advance the UE needs to detect how many cycles of SSB to achieve time-frequency synchronization, it depends on the implementation of the UE, for example, by receiving 1-3 SSB burst sets (burst sets) to restore time-frequency synchronization. Figure 8 Taking the UE detecting the most recent SSB burst set before PO as an example, the process of UE detecting SSB for time and frequency synchronization before PO is explained.

[0138] In the related art, the minimum time interval between the time domain resource where the energy-saving signal is located and DRX ON is determined by the device capability of the terminal. A terminal with a faster processing speed can use a shorter minimum time interval, see value 1 in Table 1 of the above embodiment, while a terminal with a slower processing speed needs to use a longer minimum time interval, see value 2 in Table 1.

[0139] In this example, the minimum time interval is configured to the UE through the network. The network can determine the time interval time gap 1 according to the transmission conditions of the SSB, such as the period configuration, the timing relationship with the PO, etc., and indicate it to the UE. After receiving the time interval indication information, the UE determines not to detect the energy-saving signal in the time interval before the start of the PO. For example, Fig. 9 As shown, the network configures offsets PS-offset and PS-offset2. PS-offset is used to indicate the starting point of the time domain resources for the UE to detect energy-saving signals (that is, the starting point of the time interval), and PS-offset2 is used to indicate the end point of the time domain resources for the UE to detect energy-saving signals (that is, the starting point of the time interval), that is, the energy-saving signal is not detected within the time interval indicated by PS-offset2 (that is, time gap 1). Within this time interval, the UE can restore time-frequency synchronization through SSB, so as to detect paging when PO arrives. Of course, if the energy-saving signal indicates that paging is not detected at PO, the UE may not restore time-frequency synchronization within the time interval. Specifically, the unit of the time interval may be a time slot, a subframe, a symbol, a millisecond, or a period of SSB, etc.

[0140] Furthermore, in combination with the minimum time gap 2 determined by the UE capability, the UE can further determine the time gap = Max {time gap 1, time gap 2}, that is, take a larger time gap between time gap 1 and time gap 2. This not only meets the UE capability, but also configures a longer time interval according to the network, so that the UE has enough time to perform time-frequency synchronization after receiving the energy-saving signal.

[0141] In this example, the network instructs the time interval not to detect the energy-saving signal before the start of PO or PF, so that the UE has enough time to perform time and frequency synchronization after receiving the energy-saving signal, and the network can flexibly configure the time interval according to the transmission situation of SSB.

[0142] Example 2: The minimum time interval between the time domain resource of the energy saving signal and the PO or PF is a predefined time interval.

[0143] In the related art, the minimum time interval between the time domain resource where the energy-saving signal is located and DRX ON is determined by the device capability of the terminal. Referring to Table 1 of the above embodiment, this minimum time interval is relatively short. It is difficult for the UE to complete time-frequency synchronization within this time interval.

[0144] In this example, the minimum time interval between the time domain resource of the energy-saving signal and the PO or PF may be predefined. The predefined value may not be determined based on the UE capability, but based on the requirement to complete the time-frequency synchronization recovery within the time interval. For example, assuming that the SSB period is predefined as 5ms, and the UE needs to receive 2 SSB burst sets to restore time-frequency synchronization, then the minimum time interval may be predefined as 10ms. For a 15KHz subcarrier spacing, this is 10 time slots, as shown in Table 3.

[0145] Table 3 Minimum time interval

[0146] Subcarrier spacing (kHz) Minimum time interval (slots) 15 10 30 20 60 40 120 80

[0147] In this example, the minimum time interval may be independent of the processing capability of the UE, and all values ​​may satisfy the processing capability of the UE. Only one set of values ​​may be retained in Table 3.

[0148] This example uses a predefined method to determine the minimum time interval between the time domain resource of the energy-saving signal and the PO or PF, which can save signaling overhead and is simple to implement.

[0149] Example 3: The minimum time interval between the time domain resource of the energy saving signal and the PO or PF is determined according to a predefined rule.

[0150] According to the relevant technology, all SS / PBCH blocks in the SS / PBCH burst set are sent within a 5ms time window and are repeatedly sent at a certain period. The period can be configured through high-level parameters such as ssb-PeriodicityServingCell, including 5ms, 10ms, 20ms, 40ms, 80ms, 160ms, etc. The period can be obtained through the system message SIB1.

[0151] For example, after the UE obtains the transmission period of the SSB, it can determine the minimum time interval between the time domain resources of the energy-saving signal and the PO or PF based on the period. Specifically, the relationship between the minimum time interval and the transmission period of the SSB can be predefined. For example, the predefined minimum time interval is N times the transmission period of the SSB, and N can be equal to 1, 2, 3..., depending on the number of SSBs that the UE needs to receive to complete time-frequency synchronization recovery within the minimum time interval. In this way, the UE can determine the minimum time interval. Referring to Table 2 in the above embodiment, T represents the transmission period of the SSB obtained by the UE from the system message or RRC signaling, in ms; N is a predefined coefficient. According to Table 2, the minimum time interval under different subcarrier spacings is obtained in time slots.

[0152] In this example, the minimum time interval is determined according to the transmission period of the SSB, which can ensure that there are a desired number of SSBs within the time interval for the UE to recover time and frequency synchronization. Compared with the predefined minimum time interval, it has a certain degree of flexibility.

[0153] According to the method for determining the minimum time interval between PO and energy-saving signal time domain resources in an embodiment of the present application, the UE can have sufficient time to perform time-frequency synchronization after receiving the energy-saving signal, thereby correctly receiving paging during PO.
