The following related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, which all belong to the embodiments of the present application. protected range.

Exemplarily, paging includes a Physical Downlink Control Channel (PDCCH) scrambled by a Paging-Radio Network Temporary Identifier (P-RNTI), and a Physical Downlink Control Channel (PDCCH) scheduled by the PDCCH. Shared Channel (Physical Downlink Shared Channel, PDSCH). The paging message is transmitted in the PDSCH, and the short message is 8 bits (bits) in the PDCCH.

For the UE in the RRC IDLE state or the RRC INACTIVE state, since there is no other data communication between the UE and the network, in order to save the power of the terminal, the UE can discontinuously monitor the paging channel, that is, adopt paging discontinuous reception (paging). Discontinuous Reception, DRX) mechanism. Under the paging DRX mechanism, the UE only needs to monitor paging during one paging occasion (Paging Occasion, PO) in each DRX (cycle) cycle. PO includes a series of PDCCH listening occasions, which may consist of multiple time slots. In addition, a paging frame (Paging Frame, PF) is a radio frame (for example, fixed at 10 ms), and the radio frame may include multiple POs or start positions of multiple POs.

The cycle of paging DRX is determined by the common cycle in the system broadcast and the dedicated cycle configured in high-level signaling (such as Non-Access Stratum (NAS) signaling), and the UE can take the minimum cycle between the two. For the paging cycle (Paging Cycle). On the network side, there can be multiple POs in one paging DRX cycle, and the location where the UE monitors the POs is related to the ID of the UE. For example, the PF and PO of a certain UE in a paging DRX cycle are determined as follows:

The SFN (System Frame Number) of PF can be determined by the following formula:

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

The number Index(i_s) of PO in a PF is determined by the following formula:

i_s=floor(UE_ID/N)mod Ns

The parameters in the above formula are explained as follows:

T: The DRX cycle during which the UE receives paging. The network will broadcast a default DRX cycle. If the RRC/higher layer configures the UE-specific DRX cycle for the UE, the smallest of the DRX cycle broadcast by the network and the UE-specific DRX cycle configured by the RRC/higher layer will be used as the DRX of the UE. cycle. If the RRC/higher layer does not configure the UE-specific DRX cycle for the UE, the DRX cycle broadcast by the network is used as the DRX cycle of the UE.

N: The number of PFs contained in one DRX cycle.

Ns: The number of POs contained in a PF.

PF_offset: A time domain offset used to determine PF.

UE_ID: The identity of the UE, such as 5G-S-TMSI mod 1024.

In addition, mod means a modulo operation, div means an integer division operation, and floor() means round down.

In a project for further enhancement of end-use energy savings, one objective could include:

Considering system performance aspects, specify enhancements for idle/inactive-mode UE power saving, considering system performance aspects. Such as [RAN2,RAN1].

Study and specify paging enhancements to reduce unnecessary UE paging receptions without affecting existing UEs (Study and specify paging enhancement(s) to reduce unnecessary UE paging receptions, subject to no impact to legacy UEs.). Such as [RAN2,RAN1].

Note: RAN1 will confirm and update the evaluation method (if needed) at the RAN1#100 meeting (NOTE: RAN1 to check and update, if needed, evaluation methodology in RAN1#100meeting.).

Specify means to provide potential TRS/CSI-RS occasion(s) to idle/inactive state UEs with potential TRS/CSI-RS opportunities for connected state UEs to minimize overhead impact(s) available in connected mode to idle/inactive-mode UEs,minimizing system overhead impact.). eg [RAN1].

Note: gNodeB is not required to always have TRS/CSI-RS transmission (NOTE:Always-on TRS/CSI-RS transmission by gNodeB is not required.).

That is, by designing an enhanced paging mechanism, unnecessary UE paging reception is reduced.

The reception of PO includes blind detection of PDCCH and corresponding PDSCH. The network indicates the time-frequency resource location corresponding to the PDSCH through the PDCCH, where the time slot where the PDSCH is located is determined by the time slot offset k0 of the PDSCH relative to the PDCCH, for example, the value range of k0 can be 0 to 32 time slots.

For a UE in a non-connected state, the UE also needs to perform a synchronization operation by using a synchronization signal (Synchronization Signal, SS) burst (burst) before blindly detecting the PDCCH. PDCCH has lower requirements on synchronization accuracy, and UE may need less SS burst to complete PDCCH synchronization. However, PDSCH has higher requirements on synchronization accuracy. For UEs with better channel quality, such as a higher Signal To Interference Noise Ratio (SINR), less SS bursts may be required to complete PDSCH synchronization; for channel quality Poorer eg UEs with lower SINR may require more SS bursts to complete PDSCH synchronization. The SS burst period is configured by the network, for example, the SS burst period may include 5ms, 10ms, 20ms, 40ms, 80ms and 160ms. If the period of the SS burst is greater than the time interval between the PDSCH and the PDCCH, the UE needs to complete synchronization for the PDSCH before blindly detecting the PDCCH. That is to say, the UE in the deep sleep state needs to wake up and start the synchronization operation several SS burst cycles before the PO. If the UE detects the PDCCH on its corresponding PO, the UE continues to receive the PDSCH based on the PDCCH indication. If the UE does not detect the PDCCH on its corresponding PO, the UE no longer receives the PDSCH and continues to return to the deep sleep state.

For the second case above, since the UE does not need to receive PDSCH, it is not actually necessary for the UE to wake up and start synchronization several SS burst cycles before PO. How to reduce the unnecessary synchronization time of the UE and save the power consumption of the UE is a problem that needs to be solved.

FIG. 2 is a schematic flowchart of a paging method 200 according to an embodiment of the present application. The method can optionally be applied to the system shown in Figure 1, but is not limited thereto. The method includes at least some of the following.

S210. The terminal device receives a time domain resource allocation indication.

The power-saving terminal that supports cross-carrier scheduling is the first type of terminal, otherwise it is the second type of terminal.

Optionally, in the case where the terminal type is determined based on whether the cross-carrier scheduling is supported, the terminal device may report whether the network device itself supports the cross-slot scheduling through a capability report.

Optionally, in the case where the terminal type is determined based on the power saving requirement, the terminal device with the power saving requirement may be referred to as a power saving terminal, and the terminal device without the power saving requirement may be referred to as a non-power saving terminal.

For example, if the registration request message carries a power-saving terminal indication field, reporting the registration request information may indicate that the terminal device is a power-saving terminal. If the registration request message does not carry the power-saving terminal indication field, reporting the registration request information may indicate that the terminal device is a non-power-saving terminal.

For another example, if the value of the power-saving terminal indication field carried in the registration request message is the first value, reporting the registration request information may indicate that the terminal device is a power-saving terminal. If the value of the power-saving terminal indication field carried in the registration request message is the second value, reporting the registration request information may indicate that the terminal device is a non-power-saving terminal. The first value and the second value are different.

Optionally, in the case where the terminal type is determined based on whether it supports cross-carrier scheduling and power saving requirements, if the power-saving terminals that support cross-carrier scheduling are the first type of terminals, the second type of terminals may include terminals that do not support cross-carrier scheduling.

Optionally, the terminal device may inform the network whether the terminal device supports cross-slot scheduling through a capability report.

In the embodiment of the present application, the terminal device may be configured in various ways, so that the terminal device can determine the time domain resource allocation information corresponding to the paging message based on the terminal type of the terminal device. For example, in the first manner, different PDSCH time domain resource allocation lists may be configured for different types of terminals. For another example, in the second manner, the relative offsets of the time-domain resources may be configured, so that the terminal can obtain different time-domain resource offsets by calculation. In addition, in this embodiment of the present application, for the sake of brevity of description, the PDCCH used to indicate paging may be referred to as PDCCH for short, and the PDSCH corresponding to the paging message may be referred to as PDSCH for short.

Exemplarily, the network device may send the time-domain resource allocation list in a broadcast manner.

PDSCH time domain resource allocation information corresponding to the paging message, where the PDSCH time domain resource allocation information includes a second time domain resource offset;

Wherein, the first time domain resource offset and/or the second time domain resource offset is the time slot offset of the PDSCH relative to the PDCCH.

For example, if UE1 is a power-saving terminal, after UE1 receives the PDCCH used to indicate paging, it can determine the time-domain resource offset of UE1 based on the time-domain resource allocation indication in the PDCCH and the first PDSCH time-domain resource allocation list. Shift amount K0_1.

For another example, if UE2 is a non-power-saving terminal, after UE1 receives the PDCCH used to indicate paging, if there is a second PDSCH time domain resource allocation list configured by the network device, based on the time domain resource allocation indication in the PDCCH and the first time domain resource allocation list. Two PDSCH time domain resource allocation lists, the time domain resource offset K0_2 of UE2 can be determined. If there is no second PDSCH time-domain resource allocation list, the time-domain resource offset K0_2 of UE2 may be determined based on the default PDSCH time-domain resource allocation list. Wherein, K0_2 may be smaller than K0_1.

Optionally, in Manner 2, the paging method further includes: the terminal device receiving a relative offset of time domain resources configured by the network device for the first type of terminal.

For example, for the first type of terminal, if the unit of the relative offset of the PDSCH time domain resource is the SS burst period, for example, the network configures N SSB periods (SSB_period), the UE determines the time offset of the paging PDSCH relative to the paging PDCCH, That is, the first time domain resource offset k0_1=N*SSB_period+k0. Wherein, k0 is the time domain resource offset obtained based on the PDSCH time domain resource allocation list.

For another example, for the first type of terminal, if the unit of the relative offset of PDSCH time domain resources is the number of occurrences of SS bursts, for example, the network configures N SSBs, the UE determines the time interval k0_offset based on N, and then determines the relative paging PDSCH relative offset. The time offset of the paging PDCCH, that is, the first time domain resource offset k0_1=k0_offset+k0. Wherein, k0 is the time domain resource offset obtained based on the PDSCH time domain resource allocation list.

For another example, for the second type of terminal, the time offset of the paging PDSCH relative to the paging PDCCH, that is, the second time domain resource offset k0_2=k0. Wherein, k0 is the time domain resource offset obtained based on the PDSCH time domain resource allocation list.

Optionally, the paging method further includes:

The terminal device receives a PDCCH scrambled by a Paging-Radio Network Temporary Identifier (P-RNTI), and the PDCCH scrambled by the P-RNTI is used to indicate paging.

Modulation and Coding Scheme (MCS).

Optionally, the PDCCH is used to indicate multiple PDSCHs.

Optionally, the PDCCH is used to indicate the PDSCH for the first type of terminal and the PDSCH for the second type of terminal.

Exemplarily, the PDCCH is used to indicate 2 PDSCHs, wherein one PDSCH is for the first type of terminals, and the other PDSCH is for the second type of terminals.

Exemplarily, if there are two or more terminal types, for example, there are four terminal types. The PDCCH can be used to indicate 4 PDSCHs, corresponding to 4 terminal types respectively.

Optionally, the characteristics of the multiple PDSCHs indicated by the PDCCH include at least one of the following:

The multiple PDSCHs correspond to the same frequency domain resource location;

The multiple PDSCHs correspond to the same time-domain resource size and different time-domain resource positions;

The multiple PDSCHs correspond to the same MCS or transport block size (Transport Block Size, TBS).

Optionally, the PDCCH includes a first PDCCH and/or a second PDCCH, where the first PDCCH is used to indicate a PDSCH for a first type of terminal, and the second PDCCH is used to indicate a PDSCH for a second type of terminal.

Optionally, the P-RNTI corresponding to the first PDCCH is different from the P-RNTI corresponding to the second PDCCH, or the first PDCCH and the second PDCCH are PDCCHs that monitor paging on different paging search spaces.

Exemplarily, if more terminal types are included, more PDCCHs for indicating paging may also be included, respectively indicating PDSCHs for different terminal types. Different PDCCHs have different P-RNTIs, or monitor paging PDCCHs on different paging search spaces.

Optionally, the paging method further includes: in the case that the terminal device is a first-type terminal, after the terminal device receives the PDCCH for indicating paging, using the SS burst within the first duration to continue channel measurement and synchronization, wherein the first duration includes the time interval from the moment when the PDCCH is received to the moment when the PDSCH starts to be received. In addition, channel state information reference signal (Channel State Information Reference Signal, CSI-RS) or tracking reference signal (Tracking Reference Signal, TRS) within the first duration may also be used to continue channel measurement and synchronization.

In the embodiment of the present application, based on different terminal types, the time domain resource allocation information corresponding to the paging message of the terminal device is determined, which is beneficial to realize the energy saving of the terminal. For example, for a terminal that needs energy saving, the newly configured time-domain resource allocation list and/or the relative offset of time-domain resources are used to determine the time-domain resource allocation information corresponding to the paging message of the terminal device, which can increase the time-domain resource allocation. The time domain resource offset in the information enables the terminal to continue to perform channel measurement and synchronization during the SS burst between receiving the PDCCH and receiving the PDSCH, which can ensure the receiving performance of the PDSCH. Therefore, the terminal equipment does not need multiple SSs before PO. Wake up in the burst period and start channel detection and synchronization, which can ensure the reception performance of PDSCH. For example, the terminal device can wake up in an SS burst cycle before PO and start synchronization. After the terminal receives the PDCCH, the terminal can know whether to continue to receive the PDSCH. If the terminal determines to continue to receive the PDSCH, the terminal adopts the method of this solution to determine Time domain resource offset, and can continue to perform channel measurement and synchronization from the SS burst within the time period from receiving the PDCCH to starting to receive the PDSCH.

Descriptions similar to the foregoing method 200 in the network device execution method 300 in this embodiment have similar meanings, and reference may be made to the related description of the network device such as a base station in the method 200, which is not repeated here for brevity.

The following are a few specific examples.

Example 1

The network configures one PDSCH time domain resource allocation list for the first type of terminal, and the first type of terminal and the second type of terminal use different PDSCH time domain resource allocation lists. The terminal determines the PDSCH time-domain resource allocation information corresponding to the paging message, including the time-domain resource offset k0, according to the time-domain resource allocation indication in the PDCCH scrambled by the P-RNTI and the PDSCH time-domain resource allocation list used by the terminal. Optionally, the first type of terminal is a power-saving terminal, and the second type of terminal is a non-power-saving terminal. The example could include the following steps:

Step 1. The UE determines its own terminal type, and the terminal type includes the first type terminal or the second type terminal. The division method of the first type of terminal and the second type of terminal may include:

Mode 1: According to the power saving requirement of the terminal, the power saving terminal is regarded as the first type of terminal, and the non-power saving terminal is regarded as the second type of terminal.

The UE informs the AMF whether it is a power-saving terminal or a non-power-saving terminal during the initial attach process. For example, a 1-bit (bit) power saving UE indication (Power saving UE indication) field is defined in the REGISTRATION REQUEST message. For example, a REGISTRATION REQUEST message may include the following implementations:

Option 1 (Option 1): Indicate whether the UE is a power saving terminal according to whether the Power saving UE indication field is carried in the REGISTRATION REQUEST message. For example, if there is a Power saving UE indication field, indicate that the UE is a power saving terminal, otherwise, indicate that the UE is a non-power saving terminal. For another example, if there is a Power saving UE indication field, the UE is indicated as a non-power saving terminal, otherwise, the UE is indicated as a power saving terminal.

Option 2 (Option 2): Indicate whether the UE is a power saving terminal according to the value of the Power saving UE indication field in the REGISTRATION REQUEST message. For example, if the Power saving UE indication field is 0, it indicates that the UE is a power saving terminal, and if it is 1, it indicates that the UE is a non-power saving terminal. For another example, if the Power saving UE indication field is 1, it indicates that the UE is a power saving terminal, and if it is 0, it indicates that the UE is a non-power saving terminal.

For example, considering the backward compatibility, the Power saving UE indication field may not be carried in the REGISTRATION REQUEST message sent by the R15/R16 terminal, which can also be considered as a non-power saving terminal.

Manner 2: According to the terminal capability, the terminal that supports scheduling across time slots is regarded as the first type of terminal, and the terminal without this capability is regarded as the second type of terminal.

The UE can report whether the network supports cross-slot scheduling through capability reports.

Mode 3: According to the terminal capability and the power saving requirement of the terminal, the power saving terminal that supports cross-carrier scheduling is regarded as the first type of terminal, otherwise it is regarded as the second type of terminal.

Step 2, the UE receives the network system message, and configures the first PDSCH time domain resource allocation list. Optionally, the network may also configure the second PDSCH time domain resource allocation list. The UE determines its corresponding PDSCH time domain resource allocation list according to the configuration information.

For the first type of terminal, use the configured first PDSCH time domain resource allocation list;

For the second type of terminal, if the network configures the second PDSCH time domain resource allocation list, the UE uses the second PDSCH time domain resource allocation list; if the network does not configure the second PDSCH time domain resource allocation list, the UE uses the second PDSCH time domain resource allocation list The default PDSCH time domain resource allocation list defined by the protocol.

Step 3, for a PO, when the network is to map paging (paging) to at least one UE on the PO, the way the network sends the PDCCH for indicating paging may include:

Mode 1: The network sends one PDCCH for indicating paging, and the one PDCCH can indicate two PDSCHs at the same time. The two PDSCHs are PDSCHs corresponding to the paging message. One PDSCH in the two PDSCHs is directed to a first type of terminal, see PDSCH1 in FIG. 4 ; the other PDSCH is directed to a second type of terminal, see PDSCH2 in FIG. 4 .

The two PDSCHs have the following characteristics:

The 2 PDSCHs correspond to the same frequency domain resource location;

The two PDSCHs correspond to the same time-domain resource size and different time-domain resource positions, that is, different k0 values;

The two PDSCHs correspond to the same MCS or TBS.

The above indication of 2 PDSCHs through the PDCCH is only an example and not a limitation. It should be understood that if more terminal types are set, more PDSCHs can also be indicated through the PDCCH, so as to indicate the PDSCHs for different terminal types through the PDCCH respectively.

In addition, the PDCCH used to indicate paging may include:

1 frequency domain resource allocation indication;

1 time domain resource allocation indication;

1 MCS.

Mode 2: The network sends a PDCCH indicating paging for the first type terminal and the second type terminal respectively. For this method, the first type terminal and the second type terminal use different P-RNTIs, or use different paging The PDCCH for paging is monitored in the search space.

Step 4: The UE determines, according to the received indication in the PDCCH, the time-frequency resource location for receiving the PDSCH (may be referred to as paging PDSCH) corresponding to the paging message.

For example, the frequency domain resource location is determined according to the received frequency domain resource indication in the PDCCH.

For another example, the time-domain resource location is determined according to the time-domain resource indication in the PDCCH, combined with the PDSCH time-domain resource allocation list used by the UE, and the method is as follows:

If the UE is a terminal of the first type, the PDSCH time domain resource allocation information, including k0_1 and the like, is determined according to the time domain resource indication in the PDCCH and in combination with the first PDSCH time domain resource allocation list.

If the UE is the second type of terminal, the PDSCH time domain resource allocation information, including k0_2 and the like, is determined according to the time domain resource indication in the PDCCH and in combination with the PDSCH time domain resource allocation list used by the second type of terminal.

Step 5. For the first type of terminal, after receiving the PDCCH indicating paging, the SS burst during the period before receiving the PDSCH corresponding to the paging message can be used to continue channel measurement and synchronization to ensure PDSCH reception performance. Referring to FIG. 4 , after the first type of terminal receives the PDCCH indicating paging, the time K0_1 before receiving the PDSCH corresponding to the paging message is longer than that of the second type of terminal K0_2, which can meet the requirements of channel measurement and synchronization. Therefore, the first type of terminal does not need to wake up to perform channel measurement and synchronization in multiple SS bursts before receiving the PDCCH, thereby realizing terminal energy saving.

Example 2

The network configures one PDSCH time domain resource relative offset for the first type of terminal, and the unit of the PDSCH time domain resource relative offset is the SSB period or the number of occurrences of the SS burst. The terminal determines the PDSCH time domain resource allocation information corresponding to the paging message according to the time domain resource allocation indication in the PDCCH scrambled by the P-RNTI, in combination with the PDSCH time domain resource allocation list and the terminal type corresponding to itself. The first type of terminal is a power-saving terminal, and the second type of terminal is a non-power-saving terminal.

The example could include the following steps:

Step 1. The UE determines its own terminal type, and the terminal type includes the first type terminal or the second type terminal. For the division manner of the terminals of the first type and the terminals of the second type, reference may be made to the related description of Example 1.

Step 2, the UE receives the network system message, and configures the relevant parameters of PDSCH time domain resource allocation, including: configuring the relative offset of the PDSCH time domain resources, and the relative offset of the PDSCH time domain resources is used for the first type of terminal to determine the corresponding paging message. The offset k0 corresponding to the PDSCH time domain resource. The unit of the PDSCH time domain resource offset may be an SS burst period, such as several SS burst periods, or the number of occurrences of SS bursts.

Optionally, the network configures a PDSCH time domain resource allocation list. The UE determines its corresponding PDSCH time domain resource allocation list according to whether the configuration information exists. If the network configures the PDSCH time domain resource allocation list, the UE uses the configured PDSCH time domain resource allocation list. If the network does not configure the PDSCH time domain resource allocation list, the UE uses the default PDSCH time domain resource allocation list defined by the protocol.

Step 3. For a PO, when the network wants to page at least one UE mapped to the PO, the network sends 1 PDCCH indicating paging, and the 1 PDCCH can indicate 2 PDSCHs at the same time. One PDSCH is for the first type of terminals, and the other PDSCH is for the second type of terminals.

The two PDSCHs have the following characteristics:

The 2 PDSCHs correspond to the same frequency domain resource location;

The two PDSCHs correspond to the same time-domain resource size and different time-domain resource positions;

The two PDSCHs correspond to the same MCS or TBS.

In addition, the PDCCH used to indicate paging may include:

1 frequency domain resource allocation indication;

1 time domain resource allocation indication;

1 MCS.

Step 4: The UE determines, according to the received indication in the PDCCH, the time-frequency resource position for receiving the PDSCH corresponding to the paging message.

For another example, the time domain resource location determines a k0 according to the time domain resource indication in the PDCCH and the PDSCH time domain resource allocation list used by the UE, and the method is as follows:

(1) For the first type of terminal:

Referring to FIG. 5 , if the unit of the relative offset of the first PDSCH time domain resource is an SS burst period, such as N SSB periods, the time offset k0_1=N*SSB_period+k0 of the Paging PDSCH relative to the paging PDCCH is determined.

Referring to FIG. 6 , if the unit of the relative offset of the first PDSCH time domain resource is the number of SS bursts, such as N SSBs, the UE first determines k0_offset as the time from the moment of receiving the PDCCH used to indicate paging to The time interval between the Nth complete SS burst end times, the time offset k0_1=k0_offset+k0 of the PDSCH corresponding to the UE receiving the paging message relative to the PDCCH used to indicate paging.

(2) For the second type of terminal, determine the time offset k0_2=k0 of the PDSCH corresponding to the paging message relative to the time used for indicating the paging PDCCH.

Step 5. For the first type of terminal, after receiving the PDCCH used to indicate paging, the SS burst during the period before the PDSCH reception corresponding to the paging message can be used to continue channel measurement and synchronization to ensure PDSCH reception. performance.

The paging method of the embodiment of the present application is a paging method based on UE grouping, and uses different k0 values to indicate PDSCH reception for non-power-saving terminals and power-saving terminals. For the first type of terminal, the terminal can use a longer k0_1, so that the PDCCH and the PDSCH indicated by it are not in the same time slot. Therefore, the paging method of the embodiment of the present application belongs to a paging method scheduled across time slots.

Using this method, for a UE with power saving needs, it only needs to wake up in fewer SS burst cycles before PO to complete the synchronization for the PDCCH. If the UE receives the PDCCH on its corresponding PO, the UE can use the SS burst during the period before PDSCH reception to continue channel measurement and synchronization after receiving the PDCCH to ensure the PDSCH reception performance. If the UE does not receive the PDCCH on its corresponding PO, the UE can immediately return to the sleep state. Therefore, the method can reduce unnecessary synchronization time of the UE and save power consumption of the UE.
