technical field

Downlink Control Channel, PDCCH), and receive a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) scheduled by the PDCCH, wherein the paging message is transmitted in the PDSCH.

For a terminal in a disconnected state, the terminal also needs to use a synchronization signal burst (SS burst) to perform a synchronization operation before blindly detecting the PDCCH. The detection of PDCCH has lower requirements on synchronization accuracy, and the UE may need less SS burst to complete the synchronization of PDCCH. On the other hand, PDSCH has higher requirements on synchronization accuracy. For a terminal using the paging discontinuous reception (Discontinuous Reception, DRX) mechanism, it wakes up several SS burst cycles before PO and starts to perform a synchronization operation.

Before introducing the paging method of the embodiment of the present application, the paging mechanism of the NR system is first introduced.

The main function of paging is to enable the network device to page the UE through a paging message when the UE is in the Radio Resource Control (RRC) idle (IDLE) state or the RRC inactive (INACTIVE) state. , or notify the UE of system message changes or earthquake and tsunami/public early warning information (applicable to all RRC states of the UE, including the connected state) through a short message.

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, for the purpose of power saving of the terminal, the UE can monitor the paging channel discontinuously, that is, adopt the paging discontinuous reception (Discontinuous Reception, DRX) mechanism. Under the Paging DRX mechanism, the UE only needs to monitor paging during a paging occasion (Paging Occasion, PO) in each DRX cycle (cycle).

Optionally, PO is composed of a series of PDCCH listening occasions, wherein each PDCCH listening occasion may include one or more time slots. Specifically, within one DRX cycle, the terminal device may monitor the PDCCH on the PO on the paging frame (Paging Frame, PF). PF may refer to a radio frame, for example, a fixed 10ms, and the radio frame may contain one or more POs, or the starting positions of one or more POs.

Optionally, the period of Paging DRX is jointly determined by the common period in the system broadcast and the dedicated period configured in the high-level signaling (for example, Non-Access Stratum (NAS) signaling). For example, the UE can take two The smallest cycle among them is used as Paging Cycle.

From the network point of view, a paging DRX cycle can have multiple POs. The PO position of the UE monitoring the PDCCH is related to the ID of the UE. The PF and PO of a UE monitoring the PDCCH in a Paging DRX can be determined as follows.

For example, the System Frame Number (SFN) number of PF is determined by the following formula:

(SFN+PF_offset)mod T=(T/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

Among them, T represents the DRX cycle in which the UE receives paging. In some implementations, the network can broadcast a default DRX cycle. If the upper layer of the network device, for example, the RRC layer, configures the UE with a UE-specific DRX cycle, the UE can use the network broadcast DRX cycle and the higher layer configured UE-specific DRX cycle. The smallest DRX cycle is the DRX cycle of the UE. If the upper layer of the network device does not configure the UE-specific DRX cycle for the UE, the UE may use the DRX cycle broadcast by the network as the DRX cycle of the UE.

N represents the number of PFs contained in a DRX cycle;

Ns represents the number of POs contained in a PF;

PF_offset represents a time domain offset used to determine PF;

UE_ID, for example, may be 5G-S-TMSI mod 1024, where 5G-S-TMSI is a 5G shortened Temporary Mobile Subscriber Identity (TMSI).

The reception of the paging message includes blind detection of the Physical Downlink Control Channel (PDCCH) scrambled by the Paging Radio Network Temporary Identity (P-RNTI), and reception of the PDCCH scheduled by the PDCCH. Physical Downlink Shared Channel (PDSCH). Wherein, the paging message is transmitted in the PDSCH (or in other words, the paging message is carried in the PDSCH). The network indicates the time-frequency resource location of the corresponding PDSCH through the PDCCH, where the time slot where the PDSCH is located is determined by the time slot offset value k0 of the PDSCH relative to the PDCCH, and the value range of the k0 can be, for example, 0 to 32 time slots .

For a UE in a non-connected state, the UE also needs to use a synchronization signal burst (SS burst) to perform a synchronization operation before blindly detecting the PDCCH. The detection of PDCCH has lower requirements on synchronization accuracy, and the UE may need less SS burst to complete the synchronization of PDCCH. However, PDSCH has higher requirements on synchronization accuracy. For UEs with better channel quality (for example, higher Signal to Interference plus Noise Ratio, SINR), it may require less SS burst to complete PDSCH synchronization. , while for UEs with poor channel quality (eg, lower SINR), more SS bursts may be required to complete PDSCH synchronization.

The period of the SS burst is usually configured by the network device, for example, the period of the SS burst can be 5ms, 10ms, 20ms, 40ms, 80ms or 160ms. Since the period of the SS burst needs to be larger than the time interval between the PDSCH and the PDCCH, the UE needs to complete the synchronization for the PDSCH before blindly detecting the PDCCH. That is to say, the UE in the deep sleep state needs to wake up several SS burst cycles before PO and start the synchronization operation. In one case, if the UE detects the PDCCH on its corresponding PO, the UE continues to receive the PDSCH based on the indication of the PDCCH. In another case, if the UE does not detect the PDCCH on its corresponding PO, the UE will no longer receive the PDSCH and continue to return to the deep sleep state.

For the second case above, because the UE does not need to receive PDSCH, it is actually unnecessary for the UE to wake up and start synchronization multiple SS burst cycles before PO. How to reduce the unnecessary synchronization operations of the UE to 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 provided by an embodiment of the present application. The method 200 may be executed by a terminal device in the communication system shown in FIG. 1 , and as shown in FIG. 2 , the method 200 may include at least some of the following contents:

S210, the terminal device receives the first physical downlink control channel PDCCH sent by the network device on the first paging occasion PO, where the first PDCCH is used to schedule transmission of N physical downlink shared channels PDSCH, wherein the N PDSCHs The occupied time domain resource positions are different, each PDSCH in the N PDSCHs is used to carry a paging message of one type of terminal equipment among N types, and the N≥2;

S220, the terminal device receives the specific PDSCH at the time domain resource position corresponding to the specific PDSCH among the N PDSCHs, where the specific PDSCH is used to carry a paging message of a specific type of terminal device, the The type of terminal device is the specific type.

Optionally, for the specific implementation of the first PO, reference may be made to the relevant description of the PO in the foregoing, which is not repeated here for brevity.

Optionally, in some embodiments of the present application, the first PDCCH is a P-RNTI scrambled PDCCH, and the first PDCCH is used to schedule a PDSCH carrying a paging message.

In this embodiment of the present application, the PDCCH used for scheduling paging messages may also be called paging PDCCH, that is, the first PDCCH may be paging PDCCH, and the PDSCH used for carrying paging messages may be called paging PDSCH.

In the embodiment of the present application, the first PDCCH is used to schedule transmission of multiple PDSCHs, where the time domain resource positions occupied by the multiple PDSCHs are different. The multiple PDSCHs are used to carry paging messages of multiple types of terminals, wherein each PDSCH is used to carry paging messages of one type of terminals.

That is, the network device can page multiple types of terminal devices through one PDCCH, and different types of terminals can receive the corresponding PDSCH according to their own types to obtain paging messages. In other words, the first PDCCH can schedule terminals of different types to receive corresponding PDSCHs at different time-domain resource positions.

Optionally, in some embodiments, the first PDCCH may include scheduling indication information, where the scheduling indication information is used to indicate whether the first PDCCH schedules the transmission of one PDSCH or the transmission of the N PDSCHs.

For the first PDCCH to schedule the transmission of two PDSCHs, the scheduling indication information may be used to instruct the first PDCCH to schedule the transmission of one PDSCH or the transmission of two PDSCHs, or to indicate whether to schedule the transmission of the second PDSCH transmission.

Optionally, in some embodiments, the types of terminals may be classified according to the power saving requirements of the terminal equipment, the performance of the terminal equipment, such as channel quality, and the capabilities of the terminal equipment, such as the standby ability of the terminal. It is not limited to this. As an example, terminal devices may be divided into power-saving terminals and non-power-saving terminals according to whether the terminal devices have power saving requirements. As another example, terminals can be classified into non-power-saving terminals, terminals that save power and have good channel quality, terminals that save power but have poor channel quality, etc. The application is not limited to this.

In the embodiments of the present application, different types of terminal devices may receive corresponding PDSCHs at different time domain resource positions. That is to say, the time-domain resource positions of the PDSCH of different types of terminal devices have different offsets relative to the time-domain resource positions of the first PDCCH.

For example, for a non-power-saving terminal, it can wake up a long time before PO for synchronization, so the non-power-saving terminal can complete the synchronization for PDSCH before blindly detecting the first PDCCH, that is, receiving After the first PDCCH, there is no need to perform a synchronization operation. Therefore, the offset between the time domain resource position of the PDSCH corresponding to the first PDCCH and the time domain resource position of the first PDCCH can be configured to be small.

For another example, for a power-saving terminal, if the synchronization for the PDSCH is completed before the blind detection of the first PDCCH, the terminal device does not need to receive the PDSCH when the first PDCCH is not detected. The sleep state causes unnecessary synchronization operations and increases the power consumption of the terminal. In this case, the offset between the time domain resource position of the corresponding PDSCH and the time domain resource position of the first PDCCH can be configured to be relatively large. The synchronization operation is performed within the time gap between the two devices, thereby reducing unnecessary synchronization operations caused by waking up in advance to perform synchronization, and reducing the power consumption of the terminal.

Optionally, in some embodiments, the first PDCCH includes a time domain resource indication, and the time domain resource indication is used to indicate a reference offset (denoted as k0), and the reference offset is used to determine the first The time slot offset of a PDSCH relative to the first PDCCH, where the first PDSCH is the first PDSCH transmitted among the N PDSCHs, and the first PDSCH is used to carry the N kinds of PDSCHs Paging messages for terminal devices of the first type in the type.

Optionally, the terminal of the first type is a non-power-saving terminal. After detecting the first PDCCH, the non-power-saving terminal does not need to perform a synchronization operation, so the corresponding PDSCH can be transmitted first.

Optionally, the time domain resource positions of other PDSCHs in the N PDSCHs except the first PDSCH are determined according to the reference offset k0 and an offset adjustment amount (denoted as k0_offset), wherein the offset adjustment amount k0_offset is the time domain offset of the other PDSCH relative to the first PDSCH.

In the embodiment of the present application, each PDSCH in the other N-1 PDSCHs except the first PDSCH among the N PDSCHs uses a corresponding time domain offset to determine the time domain resource position of the PDSCH.

In some embodiments, the value of the offset adjustment amount k0_offset may be absolute time, for example, the unit is symbol, or time slot, or subframe, etc., for example, 4 time slots, 3 subframes, etc.

In other embodiments, the unit of the offset adjustment amount may be K SS burst cycles, where K is a positive integer. By configuring the offset between the PDSCH and the first PDCCH, n additional SS burst cycles are added, so that for the power-saving terminal, the synchronization operation can be performed during this period, that is, it does not need to wake up in advance for synchronization, which can reduce the time of the terminal. power consumption.

Hereinafter, the configuration manner of the offset adjustment amounts corresponding to the other N-1 PDSCHs except the first PDSCH among the N PDSCHs will be described.

Configuration method 1

That is, the PDSCH corresponding to the terminal equipment of other types other than the first type has a fixed offset with respect to the first PDSCH. The terminal device can determine the offset adjustment k0_offset between the PDSCH corresponding to the terminal device of this type relative to the first PDSCH according to its own type, and further use the sum of the k0_offset and the reference offset k0 as the type of The offset of the PDSCH corresponding to the terminal device relative to the first PDCCH.

Adopting this configuration mode 1 does not need to modify the format of the existing PDCCH downlink control information (DCI), which can be better compatible with the existing technology.

Optionally, in some embodiments, the N types of terminals include power-saving terminals and non-power-saving terminals, the first PDSCH may be a PDSCH corresponding to the non-power-saving terminals, and the power-saving terminals may be Corresponding to the second PDSCH, which is transmitted after the first PDSCH, the second PDSCH has a fixed offset k0_offset relative to the first PDSCH.

Optionally, in other embodiments, the N types of terminals include non-power-saving terminals, power-saving terminals with good channel quality, and power-saving terminals with poor channel quality, and the first PDSCH may be The PDSCH corresponding to the non-power-saving terminal, the power-saving terminal with good channel quality can correspond to the second PDSCH, and the power-saving terminal with poor channel quality corresponds to the third PDSCH, wherein the second PDSCH is in the The first PDSCH is transmitted after the first PDSCH, the third PDSCH is transmitted after the second PDSCH, the second PDSCH has a fixed offset k0_offset1 relative to the first PDSCH, and the third PDSCH has a fixed offset relative to the first PDSCH. Offset k0_offset2, because the terminal with power saving and good channel quality needs less SS burst to complete the synchronization of PDSCH, and the terminal with power saving but poor channel quality needs more SS burst to complete the synchronization of PDSCH, so , k0_offset2 can be configured to be greater than k0_offset1.

Optionally, in some embodiments, the N-1 offset adjustment amounts k0_offset are configured by the network device, for example, the network device may be configured by broadcast signaling and/or radio resource control RRC signaling The N-1 offset adjustment amounts are not limited in this application.

For example, the standard may specify offset adjustment amounts corresponding to different types of terminals, and the terminal equipment may pre-store the offset adjustment amounts corresponding to the different types of terminals. The type of the terminal equipment is described, the offset adjustment amount corresponding to the pre-stored terminals of different types is determined, the target offset adjustment amount corresponding to the type is determined, and the time domain resource position of the PDSCH is further determined according to the target offset adjustment amount.

Configuration method 2

The terminal device is configured with M offset adjustment amounts, where M≧N, the network device may dynamically indicate target offset adjustment amounts used by PDSCHs corresponding to different types of terminal devices.

In some embodiments, the M offset adjustment amounts k0_offset are configured by the network device, for example, the network device may configure the M offsets through broadcast signaling and/or radio resource control RRC signaling The adjustment amount is not limited in this application.

In other embodiments, the M offset adjustment amounts k0_offset may also be preconfigured or predefined. For example, the standard may define multiple offset adjustment amounts, the terminal device may pre-store the multiple offset adjustment amounts, and the network device may dynamically indicate which offset adjustment amount is used by different types of terminals.

Optionally, in some embodiments, the method 200 further includes:

Optionally, the offset adjustment amount indication information may be carried in any downlink message or downlink channel or downlink signaling, which is not limited in this application. As an example, the offset adjustment amount indication information is carried in the first PDCCH, that is, the network device may indicate the offset adjustment amount k0_offset information at the same time when indicating the reference offset k0. By adopting this configuration mode 2, the dynamic configuration of the offset adjustment amount k0_offset can be realized, so that the flexible scheduling of the network can be realized.

In some embodiments, the offset adjustment amount indication information indicates the target offset adjustment amounts corresponding to the M offset adjustment amounts for the N−1 PDSCHs by bit mapping.

As an example, the N PDSCHs include a first PDSCH, a second PDSCH, and a third PDSCH that are transmitted sequentially from first to last, and the M offset adjustments include 5 offset adjustments, such as k0_offset0 to k0_offset4, The offset adjustment amount indication information may include 10 bits (b0-b9), which are used to indicate offset adjustment amounts corresponding to two PDSCHs to be transmitted later.

As an implementation manner, b0-b4 is used to indicate which k0_offset of k0_offset0 to k0_offset4 is used by the second PDSCH, and b5-b9 is used to indicate which k0_offset of five k0_offset0 to k0_offset4 is used by the third PDSCH. For example, a bit value of 0 indicates that the offset adjustment amount is not used, and a bit value of 1 indicates that the offset adjustment amount is adopted. If b0-b9 is 0000110000, it means that k0_offset4 is used for the second PDSCH, and k0_offset0 is used for the third PDSCH.

Optionally, in some embodiments of the present application, the method 200 further includes:

The terminal device sends a first message to the core network device, where the first message is used to notify the type of the terminal device.

In some embodiments, the core network device may be an Access and Mobility Management Function (AMF) entity, and certainly may be other core network devices, which are not limited in this application.

Optionally, the first message may be any message or signaling for interaction between the core network device and the terminal device, which is not limited in this application. As an embodiment, the first message is a registration request (REGISTRATION REQUEST) message. That is, the terminal device may notify the type of the terminal device during the registration or attach process.

Taking the first message as the REGISTRATION REQUEST message as an example, the terminal device can indicate whether the registration request message includes a terminal type indication field and/or the terminal type in the registration request message. The value of the indication field indicates the type of the terminal device.

Indication mode 1: Indicate the type of the terminal device by whether the registration request message includes a terminal type indication field.

For example, the registration request message includes a terminal type indication field, indicating that the terminal device is a power-saving terminal, and the registration request message does not include a terminal type indication field, indicating that the terminal device is a non-power-saving terminal.

Indication mode 2: The type of the terminal device is indicated by the content of the terminal type indication field included in the registration request message.

Optionally, the size of the terminal type indication field may be determined according to the number of types of terminal devices. If there are two types of terminal devices, the terminal type indication field may be 1 bit. If there are three types of terminal equipment, the terminal type indication field may be 2 bits.

Taking N types of terminals including power-saving terminals and non-power-saving terminals as an example, the value of the terminal type indication field is 1 to indicate that the terminal device is a power-saving terminal, and the value of the terminal type indication field is 0 to indicate that the terminal device is a non-power-saving terminal. electrical terminal. Alternatively, the value of the terminal type indication field is 0, indicating that the terminal device is a power-saving terminal, and the value of the terminal type indication field is 1, which indicates that the terminal device is a non-power-saving terminal.

In particular, considering the backward compatibility, for a terminal of a lower version (such as R15 or R16), since this version does not yet support the paging DRX mechanism, the registration request message sent by the terminal must not carry the terminal type indication field, In this case, the terminal device is considered to be a non-power-saving terminal. That is to say, when receiving a registration request message sent by a terminal device of a lower version, the core network device may determine that the terminal device is a non-power-saving terminal.

Further, after learning the type of the terminal device, the core network device may further send a second message to the access network device, that is, the network device in this application, where the second message is used to notify the network device of the type of the terminal device .

Optionally, the second message may be any message or signaling exchanged between the core network and the access network, which is not limited in this application. As an example, the second message is a paging message, that is, the core network device may notify the access network device of the type of the terminal device when paging the terminal device.

The indicating manner of indicating the type of the terminal through the paging message is similar to the indicating manner of indicating the type of the terminal through the registration request message, which is not repeated here for brevity.

As a specific example, a terminal type indication field may be included in the paging DRX information element (Paging DRX IE) in the paging message, which is used to indicate the type of the terminal device.

Optionally, in some embodiments of the present application, the time domain resources occupied by the N PDSCHs are of the same size.

Optionally, in some embodiments of the present application, the frequency domain resource positions occupied by the N PDSCHs are the same.

Optionally, in some embodiments of the present application, the N PDSCHs correspond to the same modulation and coding scheme (Modulation and Coding Scheme, MCS) or transport block size (Transport Block Size, TBS).

S202, the AMF entity sends a paging message to the network device (ie, the base station), and indicates whether the paging terminal is a power-saving terminal through the paging message. As an example, a terminal type indication field may be included in the Paging DRX IE in the paging message to indicate whether the terminal device is a power-saving terminal.

S203: The terminal device receives first configuration information of the network device, where the first configuration information is used to configure a k0_offset, and the k0_offset is used by the power-saving terminal to determine the time domain offset of the paging PDSCH relative to the paging PDCCH.

Optionally, the first configuration information may be configured through broadcast signaling and/or RRC dedicated signaling, or may also be configured through paging PDCCH.

S204, for a PO, when the network device wants to page at least one terminal device mapped to the PO, the network sends a first PDCCH on the PO, and the first PDCCH can schedule transmission of two PDSCHs, including the first PDCCH.

Further, when the scheduling indication information indicates that the transmission of the second PDSCH is scheduled, the terminal device uses the SS burst after the first PDCCH to perform a synchronization operation and receive the second PDSCH, which is beneficial to the terminal equipment. Power saving.

Optionally, in some other embodiments, the network device may also indicate whether the first PDCCH schedules the second PDSCH through whether the first PDCCH includes a scheduling indication field. For example, if the first PDCCH includes a scheduling indication field, it indicates that the first PDCCH schedules the second PDSCH, or if the first PDCCH does not include a scheduling indication field, it indicates that the first PDCCH does not schedule the second PDSCH PDSCH.

S205, at least one terminal device monitoring the paging message on the PO may determine the time-frequency resource position for receiving the PDSCH according to the indication of the first PDCCH.

For example, the frequency domain resource position for receiving the PDSCH is determined according to the frequency domain resource indication in the first PDCCH.

For another example, the time slot offset of the first transmitted PDSCH relative to the first PDCCH is determined according to the time domain resource indication in the first PDCCH.

As shown in FIG. 3 , if the terminal device is a non-power-saving terminal, the k0_DCI indicated in the first PDCCH can be used as the time slot offset value K0_1 of the PDSCH relative to the first PDCCH, that is, K0_1=k0_DCI, and further The reception time of the PDSCH is determined, and then the PDSCH is received at the reception time.

If the terminal device is a power-saving terminal, the sum of k0_DCI and k0_offset indicated in the first PDCCH is used as the time domain offset value K0_2 of PDSCH relative to the first PDCCH, that is, K0_2=k0_DCI+k0_offset, to further determine PDSCH reception time, and then receive the PDSCH at the reception time.

In this embodiment of the present application, for a power-saving terminal, after receiving the PDCCH indicating paging, the SS burst during the period before receiving the PDSCH can be used to continue channel measurement and synchronization to ensure the PDSCH reception performance.
