[0046] 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.

[0047] Discontinuous Reception (DRX)

[0048] In order to reduce the power consumption of terminal devices, the DRX mechanism is introduced, so that when there is no data to be received, the terminal device does not need to keep the receiver turned on all the time, but enters a state of discontinuous reception, thereby achieving the purpose of power saving. In the DRX mechanism, a DRX cycle is configured for the terminal device in the RRC connected state. A DRX cycle consists of "On Duration (corresponding to DRX activation time)" and "Opportunity for DRX (corresponding to DRX inactivation time)". During the "On Duration" time, the terminal device monitors and receives downlink channels and signals including PDCCH; during the "Opportunity for DRX" time, the terminal device does not receive downlink channels and signals such as PDCCH to reduce power consumption. The terminal device in the RRC idle state needs to receive paging messages in a similar way to the DRX mechanism. There is a paging occasion (PO) in a DRX cycle. The terminal device only monitors the paging PDCCH and paging messages within the PO, and does not monitor the paging PDCCH or receive paging messages outside the PO to achieve the purpose of power saving. During PO, the terminal device determines whether there is a paging message by detecting the paging PDCCH scrambled by the paging-radio network temporary identity (P-RNTI).

[0049] In the evolution of 5G, higher requirements are placed on the energy saving of terminal devices. For example, for the existing DRX mechanism, during each on duration, the terminal device needs to continuously detect the PDCCH to determine whether the base station schedules data transmission to itself. However, for most terminal devices, 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 terminal devices, there is room for further optimization of energy saving. The situation is similar for terminal devices in the RRC idle state receiving paging messages.

[0050] In order to optimize the energy saving of terminal devices, an energy saving signal is introduced. The energy saving signal is used in conjunction with the DRX mechanism, and the terminal device receives the energy saving signal before the on duration. When the terminal device has data transmission in a DRX cycle, the energy saving signal "wakes up" the terminal device to monitor the PDCCH during the on duration; otherwise, when the terminal device has no data transmission in a DRX cycle, the energy saving signal does not "wake up" the terminal device, and the terminal device does not need to monitor the PDCCH during the on duration. Compared with the existing DRX mechanism, when the terminal device has no data transmission, the terminal device can omit PDCCH monitoring during the on duration, thereby achieving energy saving. The time of the terminal device outside the on duration is called the DRX inactive time, and the time during the on duration is called the DRX active time. In an example, the process of indicating whether the terminal device monitors the PDCCH during the on duration through the energy saving signal is as follows. Figure 2 shown.

[0051] The energy-saving signal can be carried by the newly defined DCI format 2_6. The network configures the terminal device to detect the search space set of the PDCCH carrying DCI format 2_6. In the energy-saving signal, the number of bits required for a single user is up to 6, including 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 network notifies each user of the starting position of the energy-saving indication bit in the downlink control information (Downlink Control Information, 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 device of the total number of DCI bits and the PS-RNTI of the scrambled PDCCH.

[0052] There is a certain timing relationship between the PDCCH monitoring timing (abbreviated as PDCCH monitoring timing) and the time window of on duration (also known as DRX OnDuration, or DRX On). The network configures a time offset 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 timing. The end point of the PDCCH monitoring timing is determined by the device capability of the terminal device. The terminal device needs to perform operations such as device wake-up and initialization after wake-up within the minimum time interval before on duration. Therefore, the terminal device does not need to monitor the energy-saving signal within the minimum time interval before on duration. Terminals with faster processing speeds can use a shorter minimum time interval, see value 1 in the table below, while terminals with slower processing speeds need to use a longer minimum time interval, see value 2 in the table.

[0053]

[0054] Table 1

[0055] 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 monitoring opportunity after the starting point (the PDCCH monitoring opportunity is 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 device monitors the energy-saving signal at the monitoring position indicated by the dotted box. Here, the time position indicated by the monitoring position PS-offset indicated by the dotted box is a complete PDCCH monitoring opportunity after the starting point.

[0056] Paging

[0057] In the NR system, the network can send paging to terminal devices in RRC idle state and RRC inactive state. The paging process can be triggered by the core network or the base station, and is used to send paging requests to terminal devices in RRC idle state and RRC inactive state, or to notify system information updates, and notify terminal devices to receive earthquake tsunami warning information (ETWS) and commercial mobile warning services (CMAS) and other information. After receiving the paging message from the core network, the base station interprets the content, obtains the tracking area identity (TAI) list (ie, TAlist) of the terminal device, and performs air interface paging in the cells belonging to the tracking areas 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 terminal device. After receiving the paging message from the core network, the base station aggregates the paging messages of terminal devices with the same PO into one paging message, and transmits it to the relevant terminal devices through the paging channel. The terminal device receives the paging parameters through the system message, calculates the PO in combination with its own UE_ID, and receives the paging message on the corresponding PO. The paging message is carried by the Physical Downlink Shared CHannel (PDSCH). The terminal device obtains the paging indication information by detecting the PDCCH encrypted with P-RNTI, thereby receiving the paging message. The terminal device in the RRC idle state will save power through DRX. The PO on the PF in a DRX cycle monitors the PDCCH encrypted with P-RNTI, and then receives the paging message. The terminal device obtains the DRX-related configuration information from SIB2.

[0058] PF indicates the system frame number on which the paging message should appear, and PO indicates the possible time of appearance. A PF may include one or more POs. In each DRX cycle or paging cycle, the terminal device only needs to monitor its own PO.

[0059] A system frame number (SFN) that satisfies the following formula can be used as a PF frame:

[0060] (SFN+PF_offset)mod T=(T div N)*(UE_ID mod N);

[0061] In PF, the index (index) of the PO corresponding to the terminal device, i.e., i_s, can be calculated according to the following formula.

[0062] i_s=floor(UE_ID / N)mod Ns.

[0063] Among them, T represents the DRX cycle of the terminal device. If the default DRX cycle indicated in the system message is recorded as T_sib, if the DRX value T_ue of the terminal device has been configured, then T=min(T_ue,T_sib); if T_ue is not configured, the default value indicated in the system message is used, T=T_sib. UE_ID=(5G-S-TMSI mod 1024), 5G-S-TMSI is the terminal device identification information. N is the number of PFs in T. Ns is the number of POs in a PF. PF_offset is used to determine the frame offset of PF. As an example, the position of PF in a DRX cycle and the position of PO in PF are as follows. Figure 5 shown.

[0064] The terminal device in the RRC idle state periodically monitors the paging PDCCH on its corresponding PO. However, in actual situations, the probability of the terminal device being paged may not be high. The terminal device periodically monitors the paging PDCCH on the corresponding PO, but fails to monitor the paging PDCCH sent to itself, which will cause a waste of power. Similar to the energy saving of terminal devices in the RRC connected state, the energy saving of receiving paging messages by terminal devices in the RRC idle state is optimized, and similar energy-saving signals are introduced. A power-saving signal is called Paging Early Indication (PEI), which is used to indicate whether the terminal device monitors the paging PDCCH on the PO before the target PO arrives. The energy-saving signal can be a sequence-based signal or a signal based on the PDCCH channel. Among them, the use of the PDCCH channel to carry the energy-saving signal can follow the existing PDCCH design, so it is easy to be compatible and multiplexed with the existing system and other channels. The energy-saving signal based on the PDCCH channel can also carry more energy-saving information, for example, it can carry sub-grouping information to indicate the sub-group corresponding to the energy-saving information. Here, the sub-grouping is a further grouping of multiple terminal devices corresponding to one PO calculated by UE_ID. The sub-grouping information combined with the energy-saving information can more precisely indicate whether the terminal device needs to receive paging at the target PO. Figure 6 As shown, an energy saving signal indicates whether terminal devices of one or more subgroups monitor the paging PDCCH on the corresponding PF or PO.

[0065] In NR technology, for terminal devices in RRC idle state, the base station does not know which beam to use to send paging to the terminal device, so it uses beam scanning to send paging. In order to support multi-beam transmission of paging, a PO is defined as a group of PDCCH monitoring opportunities, and a PF can contain one or more POs or the starting time point of PO. For the case where SearchSpaceId=0 of the paging search space, since each synchronization signal block (SS / PBCH Block, SSB) index corresponds to a PDCCH monitoring opportunity, and different SSB indices correspond to different beams, multiple PDCCH monitoring opportunities corresponding to different SSB indices of a PO can support multi-beam transmission of paging. When SearchSpaceId≠0 of the paging search space, a PO contains "S*X" consecutive PDCCH monitoring opportunities, where S is the number of SSBs actually transmitted, and S is indicated by the ssb-PositionsInBurst information in SIB1; X represents the number of PDCCH monitoring opportunities corresponding to each SSB, and X is indicated by the nrofPDCCH-MonitoringOccasionPerSSB-InPO information. When the parameter X is not configured, the value of X is 1. For the [x*S+K]th PDCCH monitoring opportunity in a PO, it corresponds to the Kth actually transmitted SSB, where x=0,1,…,X-1, K=1,2,…,S. For example, S=8, X=2, then one PO includes 16 PDCCH monitoring opportunities, and the SSB index corresponding to the 16 PDCCH monitoring opportunities in chronological order is "0123456701234567", where the index numbers of 8 SSBs are 0-7.

[0066] SSB transmission

[0067] The synchronization signal in NR is given in the form of SSB, including the primary synchronization signal (PSS), the secondary synchronization signal (SSS) and the physical broadcast channel (PBCH), where PSS occupies one symbol, SSS occupies one symbol, and PBCH occupies two symbols. The time-frequency resources occupied by PBCH include the demodulation reference signal (DMRS), which is used for demodulation of PBCH.

[0068] The SSB in the NR system covers the entire cell through multi-beam scanning, which is convenient for terminal devices in the cell to receive. The multi-beam transmission of SSB is achieved by defining a synchronization signal block burst group (SSB burst set), which can also be called an SSB set. An SSB burst set contains one or more SSBs, and an SSB is used to carry the synchronization signal and broadcast channel of a beam. Therefore, an SSB burst set can contain the synchronization signals of up to L beams in the cell, where L is related to the frequency band of the system, for example: the frequency band range is less than 3GHz, L=4; the frequency band range is greater than or equal to 3GHz and less than 6GHz, L=8; the frequency band range is greater than or equal to 6GHz and less than 52.6GHz, L=64.

[0069] All SSBs in the SSB burst set are sent within a 5ms time window, that is, within a half-frame range, and are repeatedly sent with a certain period. The period of SSB is configured by the high-level parameter ssb-PeriodicityServingCell. As an example, the period of SSB includes: 5ms, 10ms, 20ms, 40ms, 80ms, 160ms, etc.

[0070] For terminal devices in RRC idle state and RRC inactive state, the terminal device wakes up in advance from the "sleep" state to perform time-frequency synchronization and automatic gain control (AGC) through SSB. In order to reduce the power consumption caused by the terminal device waking up in advance to receive SSB, it is necessary to define the position of the appropriate PEI listening time window (called the target time window) so that the terminal device can stop detecting the SSB burst set according to the instruction of the PEI when it does not need to monitor the corresponding PO to reduce power consumption. In some optional methods, the method of defining the position of the PEI listening time window includes determining it according to the time offset of the PEI listening time window from the previous SSB burst set; in other optional methods, the method of defining the position of the PEI listening time window includes determining it according to the offset of the PEI listening time window from the start time of the PO or PF.

[0071] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily 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. The embodiments of the present application include at least part of the following contents.

[0072] Figure 7 is a flow chart of a method for determining a time window provided in an embodiment of the present application, such as Figure 7 As shown, the method for determining the time window includes the following steps:

[0073] Step 701: The terminal device determines a target time window, which is used to monitor energy-saving signals. The target time window includes one or more monitoring opportunities; wherein the position of the target time window is determined based on at least one of the position of the target SSB set and the position of the target paging unit.

[0074] In the embodiment of the present application, the target time window refers to the monitoring time window of the energy-saving signal. In some optional implementations, after the terminal device determines the target time window, it monitors the energy-saving signal at all or part of the monitoring opportunities within the target time window.

[0075] In some optional implementations, the position of the target time window is determined based on the position of the target SSB set. Further, optionally, the position of the target SSB set is determined based on the position of the target paging unit.

[0076] In some optional implementations, the location of the target time window is determined based on the location of the target paging unit.

[0077] In some optional implementations, the energy-saving signal is a PEI signal. It should be noted that the present application does not limit the name of the energy-saving signal.

[0078] It should be noted that the monitoring timing in the embodiment of the present application refers to the monitoring timing of the energy-saving signal. Taking the energy-saving signal as a PEI signal as an example, the monitoring timing refers to the PEI monitoring timing.

[0079] In some optional implementations, the energy-saving signal is carried by PDCCH, and the monitoring opportunity refers to the monitoring opportunity of the PDCCH (referred to as PDCCH monitoring opportunity for short).

[0080] In some optional implementations, the energy-saving signal is carried by a reference signal, and the monitoring opportunity refers to the transmission opportunity of the reference signal. Further, optionally, the reference signal includes at least one of the following: Tracking Reference Signal (TRS), Tracking Reference Signal (TRS), and Secondary Synchronization Signal (SSS).

[0081] In the embodiment of the present application, the terminal device determines the target time window, which can be understood as the terminal device determining the position of the target time window, such as the time domain position.

[0082] Solution 1

[0083] In an embodiment of the present application, there is a first time offset between the position of the target time window and the position of the target SSB set, and the target SSB set is the Pth SSB set before the target paging unit, where P is a positive integer.

[0084] In some optional implementations, there are M SSB sets between the target time window and the target paging unit, where M is a positive integer, P = M, or P = M + 1. In some optional implementations, the value of M is network configured or predefined.

[0085] Here, when P=M, the target SSB set is an SSB set located after the target time window and adjacent to the target time window.

[0086] Here, when P=M+1, the target SSB set is an SSB set located before the target time window and adjacent to the target time window.

[0101] As an example: the terminal device takes its corresponding PO or PF as the target paging unit, and determines the position of the target time window based on the second time offset and the position of the target paging unit.

[0102] In some optional embodiments, the second time offset is configured by the network through a first configuration parameter, based on which the terminal device determines at least one of the start time of the target time window, the end time of the target time window, and the time length of the target time window based on the first configuration parameter.

[0112] In some optional implementations, the terminal device may determine the index i_s of the PO corresponding to the terminal device by using the following formula: i_s=floor(UE_ID / N) mod Ns.

[0113] In the above scheme, T represents the DRX cycle of the terminal device. If the default DRX cycle indicated in the system message is recorded as T_sib, if the DRX value T_ue of the terminal device has been configured, then T = min (T_ue, T_sib); if T_ue is not configured, the default value indicated in the system message is used, T = T_sib.

[0125] In the above scheme of the embodiment of the present application, optionally, the end time of the target time window can be defined as follows: the end time of the last listening opportunity in the target time window.

[0126] It should be noted that the definitions of the various start times and end times in the above technical solutions can be implemented in any combination.

[0127] It should be noted that the SSB set in the above technical solution refers to the SSB burst set. For the understanding of "SSB burstset", please refer to the description of the above-mentioned related solutions.

[0128] The technical solution of the embodiment of the present application is illustrated below with reference to specific application examples. It should be noted that in the following application examples, the paging unit is PO for example, and the case where the paging unit is PF is also applicable to the following application examples. It should be noted that in the following application examples, the energy-saving signal is PEI for example, and accordingly, the monitoring opportunity can be called PEI monitoring opportunity.

[0129] Application Example 1

[0130] In the embodiment of the present application, there are M SSB sets between the monitoring time window of the PEI (ie, the target time window) and the target PO. Here, the target PO refers to the PO corresponding to the terminal device.

[0131] In order to enable PEI to be sent to the terminal device earlier and reduce the power consumption of the terminal device waking up early to receive the SSB before the target PO, the listening time window of PEI can be set before the position of the Mth SSB set before the target PO or after the position of the M+1th SSB set, that is, the listening time window of PEI is separated from the target PO by M SSB sets, where the parameter M can be network configured or predefined.

[0132] The position of the listening time window of PEI can be determined according to the position of the target SSB set, where the target SSB set is the Pth SSB set before the target PO, P=M, or P=M+1. Wherein, in the case of P=M, the position of the listening time window of PEI is determined according to the position of the Mth SSB set before the target PO, and the position of the listening time window of PEI is located before the position of the Mth SSB set before the target PO. In the case of P=M+1, the position of the listening time window of PEI is determined according to the position of the M+1th SSB set before the target PO, and the position of the listening time window of PEI is located after the position of the M+1th SSB set before the target PO.

[0133] Figure 8A schematic diagram of the temporal relationship between the position of the listening time window of the PEI and the position of the target SSB set is given, wherein the position of the target SSB set is determined based on the position of the target PO, and the target SSB set can be an SSB set immediately after the listening time window of the PEI, or can also be an SSB set immediately before the listening time window of the PEI. The network configures the temporal relationship between the position of the target SSB set and the position of the listening time window of the PEI. Specifically,

[0134] Case 1: When the target SSB set is the most recent SSB set before the target time window, the network can configure the following parameters:

[0135] Offset1: represents the time offset between the start time of the target time window and the end time of the nearest SSB set before the target time window.

[0136] Offset3: indicates the time offset between the start time of the target time window and the start time of the nearest SSB set before the target time window.

[0137] The terminal device can determine the location of the PEI's listening time window based on the above parameters of the network configuration and the location of the target SSB set.

[0138] Case 2: When the target SSB set is the closest SSB set after the target time window, the network can configure the following parameters:

[0139] Offset2: represents the time offset between the end time of the target time window and the start time of the nearest SSB set after the target time window.

[0140] Offset4: indicates the time offset between the start time of the target time window and the start time of the nearest SSB set after the target time window.

[0141] The terminal device can determine the location of the PEI's listening time window based on the above parameters of the network configuration and the location of the target SSB set.

[0142] Application Example 2

[0143] In the embodiment of the present application, there are M SSB sets between the monitoring time window of the PEI (ie, the target time window) and the target PO. Here, the target PO refers to the PO corresponding to the terminal device.

[0144] In order to enable PEI to be sent to the terminal device earlier and reduce the power consumption of the terminal device waking up early to receive the SSB before the target PO, the listening time window of PEI can be set before the target PO and separated by M SSB sets from the target PO, where the parameter M can be network configured or predefined.

[0145] The location of the PEI monitoring time window can be determined according to the location of the target PO. Figure 8 A schematic diagram of the time relationship between the position of the PEI listening time window and the position of the target PO is given. The network configures the time relationship between the position of the target PO and the position of the PEI listening time window. Specifically, the network can configure the following parameters:

[0146] Offset5: indicates the time offset between the end time of the target time window and the start time of the target PO.

[0147] Offset6: indicates the time offset between the start time of the target time window and the start time of the target PO.

[0148] The terminal device can determine the location of the monitoring time window of the PEI according to the above parameters of the network configuration and the location of the target PO.

[0149] Application Example 3

[0150] for Figure 8 The offsets 1-6 in the table are defined with reference to the target time window, target SSB set, or the start or end time of the target PO.

[0151] For a target time window, the target time window includes several listening opportunities, and the start time of the target time window can be defined as the start time of the first listening opportunity among the several listening opportunities included in the target time window. The end time of the target time window can be defined as the end time of the last listening opportunity among the several listening opportunities included in the target time window.

[0152] For a target SSB set, the start time of the target SSB set may be defined as: the start time of the half frame where the target SSB set is located; or, the start time of the first SSB in the target SSB set; or, the start time of the time slot where the first SSB in the target SSB set is located. The end time of the target SSB set may be defined as: the end time of the half frame where the target SSB set is located; or, the end time of the last SSB in the target SSB set; or, the end time of the time slot where the last SSB in the target SSB set is located.

[0153] As an example, taking the target SSB set containing 8 SSBs and the subcarrier spacing as 15kHz, the position of the SSB set in the 5ms half frame is as follows: Fig. 9 As shown, it is located in the first 4 time slots. Each time slot contains 2 SSBs, and the positions of these 2 SSBs in the time slot are as follows: Fig.10 As shown, each SSB is composed of PSS, SSS and PBCH, where PSS and SSS each occupy one symbol, and PBCH occupies 2 symbols. The start time of the target SSB set can be the start time of the 5ms half-frame where the target SSB set is located, or the start time of the first SSB in the target SSB set, or the start time of the time slot where the first SSB in the target SSB set is located. The end time of the target SSB set can be the end time of the 5ms half-frame where the target SSB set is located, or the end time of the last SSB in the target SSB set, or the end time of the time slot where the last SSB in the target SSB set is located.

[0154] For a target PO, the start time of the target PO is the start time of the time domain position of the PO, and the end time of the target PO is the end time of the time domain position of the PO.

[0155] It should be noted that the above definitions of the start time and the end time may be any combination.

[0156] The technical solution of the embodiment of the present application can conveniently determine the position of the target time window, so that the terminal device can correctly determine the position of each monitoring opportunity within the target time window, and thus correctly receive the PEI at the correct monitoring opportunity.
