Method for receiving control information and communication device

Technical field

The present application relates to the field of communications technologies, and in particular, to a method and a communication device for receiving control information.

Background technique

In order to save energy consumption of the terminal device, in a mobile communication system, for example, a long term evolution (LTE) system, a paging technology is adopted, that is, when the terminal device has no data to transmit or receive, the radio frequency modem can be turned off. When the terminal device needs to send or receive data, the paging message sent by the network device wakes up its radio modem to transmit or receive data.

In the LTE system, the paging process is: the network device sends a paging message to the terminal device in the determined time domain location, and the terminal device wakes up in the determined time domain location, first according to the cell specific reference in the downlink subframe. The cell-specific reference signals (CRS) are downlink synchronized, and after the downlink synchronization is completed, the paging message is received according to the synchronized system information, and the paging process is completed.

In the new radio (NR) system, there is no CRS in the downlink subframe. Therefore, this paging procedure of the LTE system is not applicable to such a system without CRS similar to the NR system.

In order to better understand the technical solutions provided by the embodiments of the present application, two paging processes in the prior art are first introduced. As shown in FIG. 1A to FIG. 1B, in FIG. 1A, the paging process is as follows:

A1, a mobility management entity (MME) sends a PAGING to the network device;

When an evolved packet core (EPC) needs to send data or signaling to a terminal device, for example, other users call or send short messages to the terminal device, and the terminal device has downlink data when browsing the webpage in the browser, etc. Or, when the terminal device needs to reattach, the MME sends a PAGING to the network device to initiate a paging process, and the network device receives the PAGING.

A2, the network device sends a paging message Paging to the terminal device in a specific time domain location;

After receiving the PAGING sent by the MME, the network device determines to send the paging frame of the paging message Paging to the terminal device according to the period T of the discontinuous reception (DRX) of the terminal device, the parameter nB, and the identifier UE_ID of the terminal device. (paging frame, PF) and paging occasion (PO) subframes. The value of the parameter nB may be the number of paging occasions in a DRX cycle T. The paging occasion here is not limited to the paging occasion of one terminal device. Specifically, the PF is indicated by the system frame number SFN, and the SFN corresponding to the PF satisfies the following expression: SFN mod T=(T div N)*(UE_ID mod N), where N is the minimum value of T and nB, The mod function represents the modulo operation, the div function represents the division operation, and the PO is a sub-frame on the PF, which is indicated by i_s, where i_s satisfies the following expression: i_s=floor(UE_ID/N) mod Ns, floor function representation Round down the operation, Ns is the maximum of 1 and nB/T. Then, the network device sends a paging message Paging to the terminal device on the PO of the PF.

A3. The terminal device monitors and receives the paging message Paging in a specific time domain location.

Before monitoring the paging message Paging, the terminal device determines the PF and PO for monitoring the paging message Paging in the same manner as in step a2, and then wakes up in the determined PF in the PO or before the PO, according to the downlink. The CRS in the subframe performs downlink synchronization to obtain downlink timing. After the downlink synchronization is completed, the paging message Paging is monitored and received according to the downlink timing.

It should be noted that the PO determined in step a2 indicates that the network device can send a paging message Paging to the terminal device on the PO, and the network device determines, according to the actual situation, whether the paging message Paging needs to be sent on the PO, for example. When the other user calls the terminal device or sends a short message, the network device determines that the paging message Paging needs to be sent to the terminal device on the PO, and the network device may send the paging message Paging on a PO of the terminal device, when there is no When the downlink data or signaling needs to be sent to the terminal device, the network device may also not send the paging message Paging on a certain PO of the terminal device. Therefore, in order to ensure that the terminal device can receive the paging message Paging when the network device sends the paging message Paging, the terminal device needs to monitor the paging message Paging on each determined PO, when the network device sends on a certain PO. The paging message Paging, the terminal device receives the paging message Paging.

In addition, since the paging message Paging is carried on the PDSCH, the terminal device needs to monitor or receive the paging DCI before monitoring or receiving the paging message, wherein monitoring or receiving the paging DCI and the above monitoring or receiving paging message Paging The process is the same.

In the paging procedure shown in FIG. 1A, the paging procedure is initiated by the MME. In actual use, the paging process can also be initiated by the network device, as shown in FIG. 1B, and the paging process is as follows:

B1, the network device sends a paging message Paging to the terminal device in a specific time domain location;

When the network device determines system information, such as a master information block (MIB) or a system information block (SIB), the network device determines to send to the terminal device by using the method in step a2. The time domain location of the paging message is advertised, and then the paging message Paging is sent to the terminal device at the determined time domain location.

B2. The terminal device monitors and receives the paging message Paging at a specific time domain location.

B2 is the same as a3, and will not be described here.

In the prior art, before monitoring or receiving the paging message Paging and/or Paging DCI, the terminal device first performs downlink synchronization according to the CRS. Since the CRS is sent in each downlink subframe, the terminal device only needs to be monitored. Or waking up before receiving the time domain location or time domain location of the paging message Paging and/or Paging DCI, and completing the downlink synchronization by using the CRS in the downlink subframe transmitted near the time domain location and/or the time domain location, The paging message Paging can be monitored or received at the time domain location.

Since there is no CRS in the downlink subframe in the NR system, such a paging procedure in the prior art is not applicable to such a system without CRS similar to the NR system.

In view of this, the embodiments of the present application provide a method and an apparatus for transmitting and receiving control information, which are used to send or receive control information.

The technical solution of the embodiment of the present application can be applied to the NR system, the narrow band internet over things (NB-IoT) system, and can also be applied to the future-oriented communication technology. The system described in the embodiment of the present application is for clearer. The technical solutions of the embodiments of the present application are not limited to the technical solutions provided by the embodiments of the present application, and those skilled in the art may know that the technical solutions provided by the embodiments of the present application are similar to the following. Technical issues are equally applicable.

The technical solutions provided by the embodiments of the present application are described in the following with reference to the accompanying drawings. In the following description, the technical solution provided by the present application is applied to the application scenario shown in FIG. 2, and the network device is included in FIG. A plurality of terminal devices located within the coverage of the network device, the network device may send paging messages to the plurality of terminal devices at different time domain locations.

It should be noted that, in the scenario shown in FIG. 2, only the interaction between one network device and multiple terminal devices is taken as an example, and the application scenario of the present application should not be limited. In a practical application scenario, multiple network devices and multiple terminals may be included. For example, a terminal device may perform data transmission with only one network device, and may also perform data transmission with multiple network devices, which is not limited in the embodiment of the present application.

Please refer to FIG. 3 , which is a flowchart of a method for sending and receiving control information according to an embodiment of the present application. The flowchart is described as follows:

Step 301: The network device sends synchronization information and parameter information.

In the embodiment of the present application, the network device may be a network device in the NR system or a network device in the NB-IoT system. For convenience of description, in the following description, the network device is a network device in the NR system. For example, it may be gNB. Correspondingly, the terminal device in the embodiment of the present application is a terminal device in the NR system.

The synchronization information and parameter information are described below.

In the NR system, the synchronization information is a synchronization signal and a PBCH block (SS/PBCH block). An SS/PBCH block is composed of a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH). In the embodiment of the present application, the synchronization signal/physical broadcast channel block is simply referred to as a synchronization signal block (SSB). The SSB can be used for acquiring the time and frequency synchronization of the cell by the terminal device, detecting the physical layer cell ID, acquiring the system frame number SFN, or acquiring the master information block (MIB).

In the field in which the SSB is located, the number of candidate SSBs may be 4, 8, or 64, and the candidate SSBs in each field have respective numbers or indexes. The index of the candidate SSB may be one of 0 to (the number of candidate SSBs in the field is -1). The terminal device may determine an index of the SSB according to a Demodulation Reference Signal (DMRS) and/or a PBCH load of the PBCH in the SSB. The period of the field in which the SSB is located may be 5 ms, 10 ms, 20 ms, 40 ms, 80 ms, and 160 ms. As shown in FIG. 4, the number of candidate SSBs is 4. The period of the field in which the SSB is located may be configured by the network device. In the field in which the SSB is located, the time domain location of the candidate SSB is determined according to the subcarrier spacing of the SSB, and under the subcarrier spacing of each SSB, there is one or more candidate SSB time domain location patterns. The network device may send a candidate SSB or may not send a certain candidate SSB, and the network device may send indication information for indicating whether to send the candidate SSB. Before sending the SSB, the network device needs to determine the field in which the SSB is located, the period of the field in which the SSB is located, and the time domain position of the candidate SSB in the field in which the SSB is located. As an example, the above information can be artificially configured for the network device according to the network plan.

The parameter information includes at least one of the following: a period of a field in which the SSB is located, a period of a DRX period, a parameter nB, a period of a synchronization signal/synchronous signal/station measurement block configuration (SMTC,), and a SMTC. The offset, the duration of the SMTC. In the embodiment of the present application, the synchronization signal/physical broadcast channel block measurement time configuration is simply referred to as a synchronization signal block measurement time. One or more of the parameter information may be sent in a master information block (MIB) or a system information block (SIB). One or more of the parameter information may also be sent through a radio resource control (RRC) message. For example, the DRX cycle and the parameter nB may be included in the system information SIB2.

The SMTC is used to instruct the terminal device to perform time resources for SSB based measurements. The SSB-based measurement includes at least one of: a synchronization signal reference signal received power (SS-RSRP), a synchronization signal reference signal received quality (SS-RSRQ), and SS signal-to-noise and interference ratio (SS-SINR). The terminal equipment needs to measure the SS-RSRP and SS-RSRQ of the serving cell in each DRX cycle. The terminal device measures the time domain locations of SS-RSRP, SS-RSRQ, and SS-SINR in the SMTC. The SMTC is configured for network devices. The period of the SMTC may be one of 5ms, 10ms, 20ms, 40ms, 80ms, and 160ms; the offset of the SMTC is related to the period of the SMTC, and the offset is 0 to (the period of the SMTC) One of -1), for example, when the period of the SMTC is 5 ms, the offset may be one of 0, 1, 2, 3, 4, and the offset is 10 ms when the period of the SMTC is 10 ms. The value can be one of 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. When the period of the SMTC is other values, the value of the offset is deduced by analogy. No longer repeat; SMTC duration can be one of 1ms, 2ms, 3ms, 4ms, 5ms. The network device can configure the period, offset, and duration of the SMTC according to the actual situation, which is not limited here. For example, the network device can configure the SMTC according to the time domain location sent by the SSB. Optionally, the network device may configure the SMTC according to the time domain location sent by the SSB in the local cell and/or the time domain location sent by the SSB in the neighboring cell.

The network device can configure the value of nB according to the actual situation. There is no restriction here. For example, the network device can configure nB to be 2T, T, T/2, T/4, T/8, T/16, T/32, T. /64, one of T/128 and T/256. The parameter nB is used to indicate the density of the paging message Paging or Paging DCI.

Step 302: The terminal device acquires parameter information.

The terminal device can acquire the cell time and frequency synchronization through the SSB, and obtain the parameter information sent by the network device.

Step 303: The terminal device determines a time domain location where the control information is located.

Specifically, the terminal device determines, according to the identifier of the terminal device and the first parameter, a time domain location where the control information is located, where the first parameter includes a time domain location where the synchronization signal block is located or a time domain location where the synchronization signal block measurement time is located. The first parameter may include a time domain location where the synchronization signal block is located, and does not include a time domain location where the synchronization signal block measurement time is located, or the first parameter may include a time domain location where the synchronization signal block measurement time is located, and The time domain position where the synchronization signal block is located, or the first parameter may include the time domain position where the synchronization signal block is located and the time domain position where the synchronization signal measurement time is located. The time domain location where the synchronization signal block is located may be the time domain location of the candidate SSB, or the time domain location where the network device sends the SSB, and the time domain location where the synchronization signal block measurement time is located, that is, the time domain location where the SMTC configured by the network device is located. .

It should be noted that, in the embodiment of the present application, the time domain location where the control information is located is the frame where the control information is located, the time domain location where the SSB is located is the frame where the SSB is located, and the time domain location where the SMTC is located is the frame where the SMTC is located; Or, the time domain location where the control information is located is the location of the frame where the control information is located, the time domain location where the SSB is located is the location of the frame where the SSB is located, and the time domain location where the SMTC is located is the location of the frame where the SMTC is located; or, the control information The time domain location is the frame number of the frame where the control information is located, the time domain location where the SSB is located is the frame number of the frame where the SSB is located, and the time domain location where the SMTC is located is the frame number of the frame where the SMTC is located, in the following description.

No. SFN to represent each frame.

In addition, it should be noted that the network device may determine one or more time domain locations that can be used to send control information to the terminal device, and the network device may select one of the time domain locations to send control information to the terminal device, and the terminal device does not know. The network device actually sends the time domain location of the control information. Therefore, the time domain location of the control information determined by the terminal device is a time domain location of all network device devices that may send control information.

The identifier of the terminal device may be marked as UE_ID, where the UE_ID may be one of various information: may be an international mobile subscriber identification number (IMSI), or may be a temporary mobile subscriber identity (Serving– Temporary Mobile Subscriber Identity, S-TMSI), or the value obtained by modulo the IMSI and the integer D, marked as (IMSI mod D), or the value obtained by modulo the S-TMSI and the integer D, marked as (S-TMSI mod D), the integer D can be incremented by one for the maximum value of the system frame number, for example, D=1024.

In the embodiment of the present application, the step 303 may include, but is not limited to, the following three determining manners, and the terminal device may select one of the manners to determine according to actual conditions. It should be noted that, in any of the following three determination manners, determining the time domain location where the control information is located may be understood as being determined according to the identifier of the terminal device and the first parameter, or may be understood as the first The two determination methods or the third determination manner are one specific implementation manner of the first determination manner.

The following three ways of determining are introduced.

In the first method, the first parameter includes the frame where the SSB is located. The specific implementation is as follows:

The terminal device determines the frame in which the control information is located according to the identifier of the terminal device. In the following description, the identifier of the terminal device is the UE_ID, and the control information is the Paging DCI.

In the embodiment of the present application, the network device can be configured to send, to the terminal device, the frame where the paging DCI is located as one frame or multiple frames in the frame where the SSB is located, as shown in FIG. 5A, or the network device can be used to the terminal. The frame in which the device sends the Paging DCI is one or more frames in the frame within the preset offset position of the frame in which the SSB is located. The preset offset position may be 1 frame, as shown in FIG. 5B. Of course, the preset offset position may also be 2 frames or the like, which is not limited herein.

Specifically, as shown in the application scenario of FIG. 2, a plurality of terminal devices exist in the coverage of the network device, and the network device may be configured to send different frames of the paging DCI to different terminal devices. The terminal device determines the frame in which the paging DCI is located according to the UE_ID. For example, in a plurality of frames for transmitting a paging DCI as shown in FIG. 5A, the first frame is used by the network device to send a Paging DCI to a terminal device with UE_IDs of 0, 4, 8, and the second frame is used for The network device sends a Paging DCI to the terminal device with

UE_ID

1, 5, 9, and so on. If the UE_ID of the terminal device is 5, the terminal device determines that the SFN of the frame in which the paging DCI is located is 5.

It should be noted that, as shown in FIG. 5A, the interval between the frame where the Paging DCI is located and the frame where the SSB is located may also be 0. Therefore, in the embodiment of the present application, the frame where the Paging DCI is located and the frame where the SSB is located. The value of the interval between them is not limited.

In addition, it should be noted that, when the first parameter includes the frame in which the SMTC is located, the method for determining the frame of the paging DCI according to the frame in which the SMTC is located is the same as the foregoing method, and details are not described herein again. Optionally, when the first parameter includes the frame where the SMTC is located, the frame where the SSB is located is located in the frame where the SMTC is located.

The second method is as follows: The first parameter includes the frame where the SSB is located. The specific implementation is as follows:

In the embodiment of the present application, the interval between the time domain location where the control information is located and the time domain location where the SSB is located is determined according to the identifier of the terminal device. In the following description, the identifier of the terminal device is the UE_ID, and the control information is the Paging DCI.

In the embodiment of the present application, the network device can be configured to send, to the terminal device, the frame where the paging DCI is located as one frame or multiple frames in the frame where the SSB is located, as shown in FIG. 5C, or the network device can be used to the terminal. The frame in which the device sends the Paging DCI is one or more frames in the frame within the preset offset position of the frame in which the SSB is located. The preset offset position may be 1 frame, as shown in FIG. 5D. Of course, the preset offset position may also be 2 frames or the like, which is not limited herein.

Specifically, as shown in the application scenario of FIG. 2, a plurality of terminal devices exist in the coverage of the network device, and the network device can be used to send different frames of the paging DCI to different terminal devices. The terminal device determines the interval between the frame where the paging DCI is located and the frame where the SSB is located according to the UE_ID. For example, in the frame where multiple paging DCIs are located as shown in FIG. 5C, the interval between the first frame and the frame where the SSB is located is 0, and the first frame is used for the terminal of the network device to

UE_ID

0, 4. The device sends a Paging DCI. The interval between the second frame and the frame where the SSB is located is 2 frames. The second frame is used by the network device to send the Paging DCI to the terminal device with the UE_ID of 2, 6, and so on. If the UE_ID of the terminal device is 6, the terminal device determines that the interval between the frame where the paging DCI is located and the frame where the SSB is located is 2 frames, so that the terminal device determines that the frame of the paging DCI is the second frame in FIG. 5C.

It should be noted that, as shown in FIG. 5C, the interval between the frame where the Paging DCI is located and the frame where the SSB is located may also be 0. Therefore, in the embodiment of the present application, the frame where the Paging DCI is located and the frame where the SSB is located. The value of the interval between them is not limited.

The third way to determine:

In this embodiment, the first parameter further includes an index of the first synchronization signal block and/or a period of the terminal device monitoring control information. It should be noted that the first synchronization signal block is a synchronization signal block sent by the network device, or the first synchronization signal block is a synchronization signal block that is monitored or received by the terminal device. When the first parameter includes the time domain position where the synchronization signal block measurement time is located, the time domain position where the first synchronization signal block is located may be within the synchronization signal block measurement time. In this case, the first parameter includes multiple parameters, that is, the first parameter is a parameter set.

The period of monitoring the control information of the terminal device will be described below.

In the embodiment of the present application, the period in which the terminal device monitors the control information may be marked as T, where T may be a discontinuous reception period DRX cycle of the terminal device, where T may be configured by the network device or determined by the terminal device. For example, the terminal device reports the period of monitoring or receiving the paging message determined by the terminal device to the network device during the RRC connection process, and the T may be determined according to the value of the network device configuration and the value determined by the terminal device. For example, T is a larger value or a smaller value among the value configured by the network device and the value determined by the terminal device, for example, the value of the network device configuration is T1, and the value determined by the terminal device is T2, then T=min (T1) , T2), or T = max (T1, T2), of course, T can also be based on the value of the network device configuration and the value determined by the terminal device for other operations, such as modulo operations, etc., the value obtained, no restrictions here . In a specific implementation process, the value of T may be one of 32, 64, 128, and 256.

The specific implementation manner of the third determination mode will be described below.

In this determination mode, determining the time domain location where the control information is located may include, but is not limited to, the following two implementation manners:

The first way to achieve:

In this implementation, the first parameter includes the time domain location where the SSB is located and the index of the SSB. In the following description, the identifier of the terminal device is the UE_ID, and the control information is the Paging DCI. The network device can be used to send the frame where the paging DCI is located to the terminal device as one frame or multiple frames in the frame where the SSB is located, as shown in FIG. 5A or FIG. 5B, and details are not described herein again.

Specifically, as shown in the application scenario of FIG. 2, in the coverage of the network device, there are multiple terminal devices, and the network device can be used to send different frames of the paging DCI to different terminal devices, that is, when the UE_ID of the terminal device is When the index of the SSB is different, the network device sends a different frame to the terminal device where the paging DCI is located. For example, in a frame for transmitting a paging DCI as shown in FIG. 5A, when the index of the SSB is n ₀ , the first frame is used to send a Paging DCI to a terminal device with a UE_ID of 0, 4, when The index of the SSB is n ₁ , and the second frame is used to send the Paging DCI to the terminal device with the UE_ID of 0, 4; when the index of the SSB is n ₀ , the third frame is used for the terminal device with the UE_ID of 2, 6. The Paging DCI is sent. When the index of the SSB is n ₁ , the fourth frame is used to send the Paging DCI to the terminal device with the UE_ID of 2, 6, and so on. If the index of the SSB is n ₀ and the UE_ID of the terminal device is 6, the terminal device determines that the frame of the paging DCI is the third frame in FIG. 5C.

It should be noted that, when the first parameter includes other parameters, for example, the first parameter includes a time domain location where the SSB is located and a period in which the terminal device monitors the control information, or the first parameter includes a time domain location where the SSB is located, and an index of the SSB. When the terminal device monitors the period of the control information, the method for determining the time domain location of the control information by the terminal device is the same as the foregoing method, and details are not described herein again.

In addition, it should be noted that, when the first parameter includes the frame in which the SMTC is located, the method for determining the frame of the paging DCI according to the frame in which the SMTC is located is the same as the foregoing method, and details are not described herein again.

The second way to achieve:

In this implementation manner, the time domain location where the control information is located is a time domain location after the offset is increased by the first time domain location, where the first time domain location is based on the identifier of the terminal device and the terminal device monitoring control information. The period determined by the period is determined according to the second parameter, wherein the second parameter comprises at least one of the following parameters:

The frame where the SSB is located;

The frame where the SMTC is located;

SSB index;

The identification of the terminal device.

In the embodiment of the present application, the units of the first time domain position and the offset may be all frames. In the following description, the UE_ID of the terminal device, the control information is the paging DCI, and the period in which the terminal device monitors the control information is T is taken as an example for description.

The process of determining the first time domain location by the terminal device according to the UE_ID of the terminal device and the period T of the terminal device monitoring the paging DCI is described below. In this implementation manner, the first time domain location is a frame with the frame number SFN_1, and the specific determination method is as follows:

The terminal device determines that the specific calculation method of the first time domain location SFN_1 satisfies the following expression according to the period in which the terminal device monitors the paging DCI and the identifier UE_ID of the terminal device:

SFN_1mod T=(T/N)×(UE_ID mod N) (1)

It should be noted that, in this manner, the first parameter further includes a third parameter, and the third parameter may be the parameter nB, where N=min(T, nB). In the following description, the third parameter is taken as the parameter nB as an example.

In a possible implementation manner, the maximum value of the parameter nB is determined according to the first period or the fourth parameter, where the first period is a period of the synchronization signal block or a period of the synchronization signal block measurement time, and the fourth parameter is The interval at which the monitoring space of the control information is monitored.

Optionally, the first parameter includes a time domain location where the SSB is located, and the maximum value of the third parameter is determined according to a period of the SSB or a fourth parameter; the first parameter includes a time domain location where the SMTC is located, and the maximum value of the third parameter is according to the SMTC. The period or the fourth parameter is determined.

In the embodiment of the present application, the interval of the monitoring opportunity of the search space of the control information may also be referred to as the period of the monitoring opportunity of the search space of the control information, and the interval of the monitoring opportunity of the search space of the control information may be configured by the network device. It can also be pre-defined. For example, the interval may be fixed to be 20 ms or may be equal to the period of the SSB.

By limiting the maximum value of the parameter nB, the frame in which the Paging DCI determined by the formula (1) is located may be close to the first period or the fourth parameter, so that the terminal device may need to be long after performing downlink synchronization according to the SSB. The Paging DCI can be received in time to reduce the effectiveness of the downlink synchronization, which can improve the effectiveness of the downlink synchronization of the terminal device through the SSB when receiving the paging DCI.

The first parameter includes the time domain location where the SSB is located, and the maximum value of the parameter nB is determined according to the period of the SSB or the fourth parameter, and the maximum value of the parameter nB is described:

In the first case, the maximum value of nB is a ratio of the period T of the terminal device monitoring the control information to the period of the SSB, that is, the maximum value of nB is T/(the period of the SSB). The unit of the period of the SSB is the same as the period of the period T unit in which the terminal device monitors the control information. When the unit of the period T of the control information monitored by the terminal device is a frame, the unit of the period of the SSB is a frame.

In the second case, the maximum value of nB is a ratio of the period T of the terminal device monitoring the control information to the fourth parameter, that is, the maximum value of nB is T/(fourth parameter). The unit of the fourth parameter is the same as the period of the period T unit in which the terminal device monitors the control information. When the unit of the period T of the control information monitored by the terminal device is a frame, the unit of the fourth parameter is a frame.

Taking the control information as the Paging DCI as an example, optionally, when the period of the SSB is less than or equal to the interval of the monitoring occasion of the search space of the Paging DCI, the maximum value of nB is the interval of the monitoring opportunity of the search space of the T/Paging DCI; When the period of the SSB is greater than the interval of the monitoring timing of the search space of the Paging DCI, the maximum value of nB is T/(the period of the SSB) or the interval of the monitoring timing of the search space of the T/Paging DCI.

Since the parameter nB is configured by the network device, the value of the parameter nB of the network device configuration is not more than a value of the maximum value of the nB determined in the foregoing, for example, the value of nB is T or T/8. .

In the above manner, the period of the frame in which the paging DCI is located is greater than or equal to the period of the SSB. Therefore, the frame in which the paging DCI is located is close to the frame in which the SSB is located.

Specifically, if the maximum value of nB is determined by the first case, when the period of the SSB is >=1 frame, since the maximum value of nB is T/(the period of the SSB), according to N=min(T, nB), Then, the period of the Paging DCI of the terminal device is marked as T/N, and the minimum value of T/N is max (the period of the SSB, 1 frame), so that the period in which the network device sends the frame in which the paging DCI is located to the terminal device can be obtained. Greater than or equal to the period of the SSB. As shown in FIG. 6A, taking the period of the SSB as 0.5 frames, T=32, and nB=T as an example, according to the formula (1), the network device sends a Paging to the terminal device with the UE_ID of 0, 32, 64, . In the DCI, the SFN is SFN 0; when the network device sends the Paging DCI to the terminal device with the UE_ID of 1, 33, 65, ..., the SFN is SFN 1; the network device sends the Paging to the terminal device with the UE_ID of 2, 34, 66, ... In DCI, SFN is SFN 2, and so on. In FIG. 6A, the network device sends the frame where the paging DCI is located to the terminal device and is close to the frame where the SSB is located.

When the period of the SSB is <1 frame, since the maximum value of nB is T/(the period of the SSB), according to Ns=max(1, nB/T), at most one (1/SSB period) is used in one frame. The timing of sending the Paging DCI, therefore, the minimum value of T/N is max (the period of the SSB, 1 frame), so that it can be concluded that the period in which the network device sends the frame in which the paging DCI is located to the terminal device is greater than or equal to the SSB. As shown in FIG. 6B, taking the SSB period as 8 frames, T=32, and nB=T/8 as an example, according to formula (1), the network device sends to the terminal device with

UE_ID

0, 4, 8, . When Paging DCI, SFN is

SFN

0, 32, ...; when the network device sends Paging DCI to the terminal device with

UE_ID

1, 5, 9, ..., SFN is

SFN

8, 40, ...; network device to UE_ID is 2, 6 When the terminal device of 10, ... sends the Paging DCI, the SFN is

SFN

16, 48, ..., and so on. In FIG. 6B, the interval between the frame in which the network device sends the paging DCI and the frame in which the SSB is located is about half of the period of the SSB, and the network device sends the frame where the paging DCI is located and the SSB to the terminal device. The frames are close.

If the maximum value of nB is determined by the second case, when the period of the SSB is less than or equal to the interval of the monitoring timing of the search space of the Paging DCI, and when the interval of the monitoring timing of the search space of the Paging DCI is >=1, due to nB The maximum value is the interval of the monitoring time of the search space of the T/Paging DCI. According to N=min(T, nB), the period of the Paging DCI of the terminal device is marked as T/N, and the minimum value of T/N is max ( The period of the SSB, 1 frame), so that the period during which the network device sends the frame in which the paging DCI is located to the terminal device is greater than or equal to the SSB. As shown in FIG. 6C, the period of the SSB is 1 frame, and the interval of the monitoring time of the search space of the Paging DCI is 2 frames, T=32, nB=T/2 is taken as an example, according to the formula (1), the network When the device sends the Paging DCI to the terminal device with the UE_ID of 0, 16, 32, ..., the SFN is SFN 0; when the network device sends the Paging DCI to the terminal device with the UE_ID of 1, 17, 33, ..., the SFN is SFN 2; When the device sends a Paging DCI to a terminal device with UE_IDs of 2, 18, 34, ..., the SFN is SFN 4, and so on. In FIG. 6C, the network device sends the frame where the paging DCI is located to the terminal device and is close to the frame where the SSB is located.

When the period of the SSB is less than or equal to the interval of the monitoring opportunity of the search space of the Paging DCI, and when the interval of the monitoring time of the search space of the Paging DCI is <1, since the maximum value of the nB is T/(the monitoring of the search space of the Paging DCI) Timing interval), according to Ns=max(1, nB/T), there is at most one (the interval of the monitoring occasion of the search space of the 1/Paging DCI) in one frame, and the timing for transmitting the paging DCI, therefore, T/N The minimum value is max (the interval of the monitoring opportunity of the search space of the paging DCI, 1 frame), so that the period in which the network device sends the frame in which the paging DCI is located to the terminal device is greater than or equal to the SSB period.

When the period of the SSB is greater than the interval of the monitoring opportunity of the search space of the Paging DCI, it is the same as the first case, and details are not described herein again.

It should be noted that the maximum value of the parameter nB is related to the period of the SSB or related to the fourth parameter, and can be determined according to the size of the period of the SSB. For example, when the period of the SSB is greater than or equal to a certain threshold, the maximum value of the parameter nB is related to the period of the SSB. When the period of the SSB is less than the threshold, the maximum value of the parameter nB is related to the fourth parameter, and the value of the threshold is There are no restrictions here.

In addition, it should be noted that, in the above implementation manner, when the first parameter is the period of the SMTC, the terminal device determines that the frame where the control information is located is the same as the foregoing method, and details are not described herein again.

The manner of determining the offset will be described below.

In the embodiment of the present application, the manner of determining the offset is different according to different parameters for determining the offset, as follows.

(1) Determine the offset according to the frame in which the SMTC is located.

In the embodiment of the present application, the offset determined according to the frame in which the SMTC is located is marked as Offset_SMTC. The manner of determining the Offset_SMTC according to the frame in which the SMTC is located includes but is not limited to the following.

First, the terminal device determines that the calculation method of Offset_SMTC according to the frame in which the SMTC is located satisfies the following expression:

Offset_SMTC=SFN_SMTC+L; (2)

The SFN_SMTC is the minimum value of the frame number SFN of the frame in which the SMTC is located, or SFN_SMTC is the SFN of the frame in which the first SMTC is located from SFN 0, or SFN_SMTC is the frame distance of the first SMTC from SFN 0 The offset value of SFN 0, which is in frames. For example, the period of the frame in which the SMTC is located is 8 frames, and the SFN of the frame in which the SMTC is located is SFN 3, SFN 11, SFN 19, ..., and SFN_SMTC=3, as shown in FIG. 7A.

L is an integer and can be 0, or a positive integer, or a negative integer, or an odd number, or an even number. L can be determined in various ways. For example, L may be pre-defined, or may be pre-agreed by the network device and the terminal device, may be configured by the network device, or may be configured by the network device according to other parameters, for example, The interval of the monitoring timing of the search space of the control information is determined, and L can also be determined according to a calculation method that satisfies the following expression:

L=B+((SFN_SMTC+C)modA); (3)

Wherein A, B and C are integers. For example, the value of A may be 2, the value of B may be 1, and the value of C may be -1, and the expression of L is: L=1+((SFN_SMTC-1) mod 2).

Of course, L can also adopt other determination methods, and is not limited herein. L can adjust the interval between the frame in which the Paging DCI is located and the frame in which the SMTC is located.

Second, the terminal device determines that the calculation method of Offset_SMTC according to the frame in which the SMTC is located satisfies the following expression:

Offset_SMTC=floor((SFN_SMTC+L)/B)*B; (4)

The SFN_SMTC is the same as the first one, and is not described here.

B is a positive integer, and B is determined in various ways. For example, B may be pre-defined, or may be pre-agreed by the network device and the terminal device, may be configured by the network device, or may be configured by the network device. Other parameters, for example, the interval of the monitoring opportunity of the search space of the control information, for example, the value of B is equal to the interval of the monitoring opportunity of the search space of the Paging DCI, and the unit is a frame.

L is an integer and can be 0, or a positive integer, or a negative integer, or an odd number, or an even number. L may be pre-defined, or may be pre-agreed by the network device and the terminal device, or may be configured by the network device, and may be determined in other manners, and is not limited herein. For example, the value of B is 2, the value of L is 1, and the calculation method for obtaining Offset_SMTC is: Offset_SMTC=floor((SFN_SMTC+1)/2)*2.

Third, the terminal device determines that the calculation method of Offset_SMTC according to the frame in which the SMTC is located satisfies the following expression:

Offset_SMTC=ceil((SFN_SMTC+L)/B)*B; (5)

The SFN_SMTC is the same as the first one, and the values of B and L are the same as those in the second type, and are not described here. The ceil() function is a rounded up function. When the value of B is 2 and the value of L is 1, the method for obtaining Offset_SMTC is: Offset_SMTC=ceil((SFN_SMTC+1)/2)*2. When the value of B is 2 and the value of L is 0, the calculation method for obtaining Offset_SMTC is: Offset_SMTC=ceil((SFN_SMTC)/2)*2.

Fourth, determining that Offset_SMTC is the frame number of the frame in which the monitoring space of the search space of the Lth control information after the frame in which the first SMTC is located, or determining that Offset_SMTC is the L before the frame in which the first SMTC is located The frame number of the frame in which the monitoring space of the control information is located. In the embodiment of the present application, the frame in which the first SMTC is located may also be understood as the smallest SMTC of the frame number of the frame in which the SMTC is located. L is 0 or a positive integer, and L may be pre-defined, or may be pre-agreed by the network device or the terminal device, or may be configured by the network device, and is not limited herein.

After determining the offset, the time domain location where the Paging DCI is located is determined to be the first time domain location plus the time domain location of the offset Offset_SMTC according to the first time domain location and the offset Offset_SMTC. The terminal device determines that the frame number of the frame in which the paging DCI is located is SFN=(SFN_1+Offset_SMTC) mod Num_SFN, or SFN mod T=((T/N)×(UE_ID mod N)+Offset_SMTC) mod T, or, (SFN -Offset_SMTC) mod T = (T / N) × (UE_ID mod N), or, (SFN + Offset_SMTC) mod T = (T / N) × (UE_ID mod N). In the embodiment of the present application, the number of SFNs is marked as Num_SFN, and optionally, the maximum value of Num_SFN=SFN is +1.

As shown in FIG. 7B, with the SMTC period of 8, T=32 frames, nB=T/8, SFN_SMTC=4, L=0 as an example, the SFN_1 is calculated according to the formula (1), and the network device is obtained with the UE_ID being 0. When the terminal device of 4, 8, ... sends the Paging DCI, SFN_1 is

SFN

0, 32, ..., when the network device sends the Paging DCI to the terminal device with the UE_ID of 1, 5, 9, ..., SFN_1 is

SFN

8, 40,... When the network device sends the Paging DCI to the terminal device with the UE_ID of 2, 6, 10, ..., SFN_1 is

SFN

16, 48, ..., and so on. It can be seen from the frame in which the Paging DCI is transmitted on the second time axis in FIG. 7B that the distance between the SFN_1 and the frame where the SMTC is located is calculated by the formula (1).

According to Offset_SMTC=SFN_SMTC+L, Offset_SMTC=4 is obtained. Then, according to the formula SFN=(SFN_1+Offset_SMTC) mod Num_SFN, when the network device sends the Paging DCI to the terminal device with the UE_ID of 0, 4, 8, ..., the SFN is

SFN

4, 36, ..., and the network device has a UE_ID of 1 When the terminal device of 5, 9, ... sends the Paging DCI, the SFN is

SFN

12, 44, ..., when the network device sends the Paging DCI to the terminal device with the UE_ID of 2, 6, 10, ..., the SFN is

SFN

20, 52, ..., and so on. It can be seen from the frame in which the Paging DCI is transmitted on the third time axis in FIG. 7B and the frame in which the SMTC is located, and the SFN determined according to the formula SFN=(SFN_1+Offset_SMTC) mod Num_SFN coincides with the frame distance in which the SMTC is located. In this way, the terminal device can complete the SS-RSRP and SS-RSRQ measurement in the frame in which the SMTC is located, and the monitoring and/or receiving process of the Paging DCI in a wake-up process.

(2) Determine the offset according to the frame in which the SSB is located.

The process of determining the offset according to the frame in which the SSB is located is the same as the offset determined according to the frame in which the SMTC is located in (1), where SFN_SMTC is the minimum value of the frame number SFN of the frame in which the SSB is located, or SFN_SMTC is the slave SFN 0. Start the SFN of the frame where the first SSB is located, or SFN_SMTC is the offset value of the frame distance SFN 0 where the first SSB is located from SFN 0, and the offset value is in units of frames. In the fourth method, it is determined that Offset_SMTC is the frame number of the frame in which the monitoring time of the search space of the Lth control information after the frame in which the first SSB is located, or before determining that Offset_SMTC is the frame in which the first SSB is located The frame number of the frame in which the search space of the Lth control information is located. In the embodiment of the present application, the frame in which the first SSB is located may also be understood as the smallest SSB of the frame number of the frame in which the SSB is located. I will not repeat them here.

(3) Determine the offset according to the UE_ID of the terminal device.

In the embodiment of the present application, the offset determined according to the UE_ID of the terminal device is marked as Offset_UE. The manner of determining Offset_UE according to the UE_ID of the terminal device includes but is not limited to the following manners:

The calculation method of the terminal device determining the Offset_UE according to the UE_ID of the terminal device satisfies the following expression:

Offset_UE=I*(floor(UE_ID/N/G)modE); (6)

Where E is the number of frames used to send control information in the vicinity of the first time domain location. If the first time domain location is determined by the network device according to the frame in which the SSB is located, then E is used near the frame where the SSB is located. The number of frames in which control information is sent. E, G, and I can be pre-defined or network device configured. I is the interval of the monitoring timing of the search space for the control information. The network device can set the values of E and I according to the actual situation. For example, if the network device can set the value of E to 2 and the value of I to 2, there are 2 for sending control in the vicinity of the first time domain location. The frame of information, one frame is the first time domain position, and the other frame is the frame after 2 frames from the first time domain position, as shown in FIG. 8A. It should be noted that the value of Offset_UE may be 0.

After determining the offset, the terminal device determines that the time domain location where the paging DCI is located is the first time domain location plus the time domain location of the offset Offset_UE according to the first time domain location and the offset Offset_UE. The terminal device determines that the frame number of the frame in which the paging DCI is located is SFN=(SFN_1+Offset_UE) mod Num_SFN, or SFN mod T=((T/N)×(UE_ID mod N)+Offset_UE) mod T, or, (SFN -Offset_UE) mod T = (T / N) × (UE_ID mod N), or (SFN + Offset_UE) mod T = (T / N) × (UE_ID mod N).

As shown in FIG. 8B, taking T=32, nB=T/8, G=1, and E=2 as an example, SFN_1 is calculated according to formula (1), and the terminal of the network device to UE_ID is 1, 5, 9, ... is obtained. When the device sends the Paging DCI, SFN_1 is SFN 8. When the network device sends the Paging DCI to the terminal device with the UE_ID of 2, 6, 10, ..., SFN_1 is SFN 16, and so on.

According to Offset_UE=2*(floor(UE_ID/N/G) mod E), when the network device sends the Paging DCI to the terminal device with the UE_ID of 0, 8, 16, ..., the SFN is

SFN

0, 32, ..., the network device When the terminal device with the UE_ID of 4, 12, 20... transmits the Paging DCI, the SFN is

SFN

2, 34, ..., and when the network device sends the Paging DCI to the terminal device with the UE_ID of 1, 9, 17, ..., the SFN is

SFN

8, 40, ..., when the network device sends the Paging DCI to the terminal device with the UE_ID of 5, 13, 21, ..., the SFN is

SFN

10, 42, ..., and the network device sends the Paging DCI to the terminal device with the UE_ID of 2, 10, 18... When the SFN is

SFN

16, 48, ..., when the network device sends the Paging DCI to the terminal device with the UE_ID of 6, 14, 22..., the SFN is

SFN

18, 50, ..., and so on. It can be seen from the frame in which the Paging DCI is transmitted on the second time axis in FIG. 8B, according to the formula SFN=(SFN_1+Offset_UE) mod Num_SFN, it is determined that more network devices can transmit the Paging DCI frame, and the terminal device in the NR system. When the paging capacity of the network device is limited, the number of terminals for paging in each frame can be reduced by setting multiple frames for transmitting the paging DCI, which can reduce the computational complexity of the network device. degree.

(4) Determine the offset based on the index of the SSB.

In the embodiment of the present application, the index of the SSB is marked as SSBIndex, and the offset determined according to the index of the SSB is marked as Offset_SSBIndex.

First, the association between the index of the SSB in the NR system and the frame used by the network device to transmit the Paging DCI is introduced.

In the embodiment of the present application, the frame used by the network device to send the paging DCI may be associated with the index of the SSB, or may not be associated with the index of the SSB, and the frame used by the network device to send the paging DCI is associated with the index of the SSB. In this case, the index of the SSB is associated with the frame used by the network device to send the Paging DCI, and the index of the SSB is the same as the association of the frame used by the network device to transmit the remaining minimum system information (RMSI) DCI. Among them, SSB and RMSI control resource set (CORESET) are multiplexed with three patterns, as shown in Figure 9, in the first multiplexing relationship in Figure 9, ie, pattern 1, RMSI DCI The monitoring time of the search space is 20 ms; in pattern 2/3, the monitoring time of the search space of the RMSI DCI is the same as the period of the SSB.

In the case where the SSB and RMSI CORESET multiplexing pattern is pattern1, the monitoring timing of the search space of the RMSI DCI is associated with the index of the SSB. Specifically, the terminal device can monitor the RMSI DCI in two consecutive slots. The starting slot index of the two slots is n ₀ . For the SSB whose index of the SSB is i, the terminal device determines that the n ₀ calculation method in one radio frame SFN _C satisfies the following expression:

Wherein, the radio frame SFN _C satisfies the following expression:

when

When SFN _C mod2=0; (8)

when

When SFN _C mod2=1. (9)

Wherein, M and O are configured for the network device, and μ∈{0, 1, 2, 3} is a subcarrier spacing used by a physical downlink control channel (PDCCH) carrying the RMSI DCI,

Represents the number of slots in a frame whose value is defined in the standard protocol. It can be seen that the frame in which the network device sends the paging DCI is related to the index of the SSB.

Therefore, in the embodiment of the present application, the calculation method for determining the offset according to the index of the SSB satisfies one of the following expressions, wherein the index of the SSB is SSBIndex, and the offset determined according to the index of the SSB is Offset_SSBIndex. For example:

Where J is an integer and can be 0, or a positive integer, or a negative integer.

It should be noted that Offset_SSBIndex may be 0. For example, when the SSB and RMSI CORESET multiplexing pattern is pattern2 or pattern3, Offset_SSBIndex is 0.

After determining the offset, the terminal device determines that the time domain location where the paging DCI is located is the first time domain location plus the time domain location of the offset Offset_SSBIndex according to the first time domain location and the offset Offset_SSBIndex. The terminal device determines that the frame number of the frame in which the paging DCI is located is SFN=(SFN_1+Offset_SSBIndex) mod Num_SFN, or SFN mod T=((T/N)×(UE_ID mod N)+Offset_SSBIndex) mod T, or, (SFN -Offset_SSBIndex)mod T=(T/N)×(UE_ID mod N), or,

(SFN+Offset_SSBIndex) mod T=(T/N)×(UE_ID mod N).

(5) The offset is determined according to at least two parameters of the frame in which the SSB is located, the frame in which the SMTC is located, the index of the SSB, and the UE_ID of the terminal device.

The expression for this offset can be one of the following:

1) Offset_SMTC+Offset_UE;

2) Offset_SMTC+Offset_SSBIndex;

3) Offset_UE+Offset_SSBIndex;

4) Offset_SMTC+Offset_UE+Offset_SSBIndex;

The meanings and calculation methods of Offset_SMTC, Offset_UE, and Offset_SSBIndex are the same as those in (1)-(4) in step 303, and are not described herein again.

The offset determined according to at least two parameters of the frame where the SSB is located, the frame where the SMTC is located, the index of the SSB, and the UE_ID of the terminal device is recorded as Offset, and the terminal device is based on the first time domain position and the offset Offset. Determine the time domain location where the paging DCI is located as the time domain location of the first time domain location plus the offset Offset. The terminal device determines that the frame number of the frame in which the paging DCI is located is SFN=(SFN_1+Offset) mod Num_SFN, or SFN mod T=((T/N)×(UE_ID mod N)+Offset) mod T, or, (SFN -Offset) mod T = (T / N) × (UE_ID mod N), or, (SFN + Offset) mod T = (T / N) × (UE_ID mod N).

SFN=(SFN_1+Offset_SMTC+Offset_UE) mod Num_SFN, the period of SMTC is 8, T=32 frames, nB=T/8, SFN_SMTC=4, I=2, G=1, E=2, for example, according to the formula (1) Calculate SFN_1, and obtain the terminal device that the network device sends Paging DCI to the terminal device with

UE_ID

0, 4, 8, ..., SFN_1 is SFN0, 32, ..., and the network device sends the UE_ID to 1, 5, 9, ... When the Paging DCI is sent, SFN_1 is SFN8, 40, ..., when the network device sends the Paging DCI to the terminal device with the UE_ID of 2, 6, 10, ..., SFN_1 is

SFN

16, 48, ..., and so on. It can be seen from the frame in which the Paging DCI is transmitted on the second time axis in FIG. 10 that the distance between the SFN_1 and the frame where the SMTC is located is calculated by the formula (1).

According to Offset_SMTC=SFN_SMTC+L, Offset_SMTC=4 is obtained, so that when the network device sends the Paging DCI to the terminal device with the UE_IDs of 0, 4, 8, ..., SFN=(SFN_1+Offset_SMTC) mod Num_SFN is

SFN

4, 36, ..., when the network device sends a Paging DCI to a terminal device with UE_IDs of 1, 5, 9, ..., SFN = (SFN_1 + Offset_SMTC) mod Num_SFN is

SFN

12, 44, ..., and the network device has a UE_ID of 2, 6, 10, When the terminal device of ... transmits the Paging DCI, SFN = (SFN_1 + Offset_SMTC) mod Num_SFN is

SFN

20, 52, ..., and so on. It can be seen from the frame in which the Paging DCI is transmitted on the third time axis in FIG. 10 that the frame calculated by the method of SFN=(SFN_1+Offset_SMTC) mod Num_SFN coincides with the frame in which the SMTC is located.

According to Offset_UE=I*(floor(UE_ID/N/G) modE), when the network device sends the Paging DCI to the terminal device with the UE_IDs of 0, 8, 16, ..., SFN=(SFN_LTE+Offset_SMTC+Offset_UE) mod Num_SFN is SFN. 4, 36, ..., when the network device sends the Paging DCI to the terminal device with the UE_ID of 4, 12, 20..., SFN=(SFN_LTE+Offset_SMTC+Offset_UE) mod Num_SFN is

SFN

6,38,..., the network device has a UE_ID of 1 When the terminal device of 9, 17, ... transmits the Paging DCI, SFN = (SFN_LTE + Offset_SMTC + Offset_UE) mod Num_SFN is

SFN

12, 44, ..., and the network device sends Paging to the terminal device with UE_ID of 5, 13, 21, ... In DCI, SFN=(SFN_LTE+Offset_SMTC+Offset_UE) mod Num_SFN is

SFN

14,46,..., when the network device transmits Paging DCI to the terminal device with UE_IDs of 2, 10, 18..., SFN=(SFN_LTE+Offset_SMTC+Offset_UE) When mod Num_SFN is

SFN

20, 52, ..., when the network device sends a Paging DCI to a terminal device with

UE_IDs

6, 14, 22..., SFN=(SFN_LTE+Offset_SMTC+Offset_UE) mod Num_SFN is

SFN

22, 54, ... analogy. When the number of terminal devices in the NR system is large, and the paging capacity of the network device is limited, a plurality of frames for transmitting the paging DCI may be set, thereby reducing the number of paging devices in each frame. Reduce the computational complexity of network devices.

(6) After determining the first time domain position SFN_1 and determining the offset according to any one of the above (1) to (5), determining the frame number SFN of the frame for transmitting the control information may further satisfy the following One of the expressions:

SFN=(SFN_1+Offset_SMTC);

SFN=(SFN_1+Offset_UE);

SFN=(SFN_1+Offset_SSBIndex);

SFN=(SFN_1+Offset_SMTC+Offset_UE);

SFN=(SFN_1+Offset_SMTC+Offset_SSBIndex);

SFN=(SFN_1+Offset_UE+Offset_SSBIndex);

SFN=(SFN_1+Offset_SMTC+Offset_UE+Offset_SSBIndex);

SFN=(SFN_1+Offset_SMTC+Offset_UE+Offset_SSBIndex).

Step 304: The terminal device determines a time slot in which the control information is located.

In this embodiment of the present application, the network device determines, according to the identifier of the terminal device and/or the index of the SSB, the time slot in which the control information is in the frame in which the control information is located. In the following description, the identification of the terminal device is the UE_ID of the terminal device, and the control information is the Paging DCI as an example.

When there is more than one time slot for transmitting control information in one frame, as shown in FIG. 11, there are two time slots for transmitting the paging DCI in one frame, and then it is determined according to the UE_ID of the terminal device for sending Paging. For the time slot of the DCI, the following formula can be used: i_s=floor(UE_ID/N/F) mod Ns, N=min(T, nB), Ns=max(1, nB/T), and Ns represents a frame. The number of time slots used to send control information. F is a positive integer, F can be predefined, or it can be configured by a network device. Optionally, in determining a frame for transmitting control information, if Offset_UE=I*(floor(UE_ID/N) mod E) is used, F may be equal to E. Optionally, in the frame for determining to send the control information, if Offset_UE is not used, F may be equal to 1. I_s indicates the number or index of the corresponding slot. For example, i_s=0 indicates the first slot used to transmit the paging DCI in the frame for transmitting control information, and i_s=1 indicates the second one in the PF for transmission. The time slot of the Paging DCI, i_s = Ns-1, indicates the Nsth slot in the frame for transmitting control information for transmitting the paging DCI.

It should be noted that the number of timeslots used to send the Paging DCI in a frame may be configured by the network device, or may be pre-agreed with the terminal device, and is not limited herein.

The implementation manner of determining, by the terminal device, the time slot of the control information in the frame in which the control information is located may include, but is not limited to, the following multiple manners:

The first way:

According to the association between the frame used by the network device for transmitting the paging DCI and the index of the SSB, the terminal device may determine the time slot used by the network device to send the paging DCI by using formula (7). (7) has been described in (4) in step 303, and will not be described again.

It should be noted that, in the frame used for sending the Paging DCI, the network device may send the Paging DCI in one time slot, or may send the Paging DCI in one of two or more consecutive time slots. The network device is sent in one time slot, and the index determined by the terminal device according to formula (7) is an index of the time slot. If the network device sends in one of two or more consecutive time slots, the terminal The index determined by the device according to equation (7) is the index of the starting time slot of the two or more consecutive time slots. When the SSB and RMSI CORESET multiplexing pattern is pattern1, it can be determined in the first way.

It should be noted that, in the frame for transmitting the paging DCI, the terminal device may monitor the paging DCI in one time slot, and may also monitor the paging DCI in two or more consecutive time slots, if the terminal device is at one time In the gap monitoring, the index determined according to formula (7) is the index of the time slot. If the terminal device monitors in two or more consecutive time slots, the index determined according to formula (7) is the two or An index of the starting time slot of a plurality of consecutive time slots. When the multiplexing pattern of the resources in the SSB and the RMSI CORESET is pattern1, it can be determined in the first manner.

The second way:

The terminal device determines the time slot of the paging DCI according to the slot number of the SSB indexed i in the frame in which it is located. Specifically, the terminal device determines that in a frame for transmitting the paging DCI, the slot index n ₀ of the paging DCI is the sum of the slot number and K in the frame in which the SSB indexed i is located, where K For an integer, K can be 0, can be a positive integer, and can be a negative integer. When the SSB and RMSI CORESET multiplexing pattern is pattern2 or pattern3, it can be determined in the second way.

The terminal device determines the time slot of the paging DCI according to the slot number of the SSB whose index is i in the frame in which it is located and the UE_ID of the terminal device. Specifically, when the frame used by the network device to send the paging DCI is associated with the index of the SSB, and there is more than one time slot for transmitting the paging DCI in one frame, the period of the SMTC is 0.5 frames, and the network device configures nB. =2T is taken as an example. In this case, two of the PFs are used to transmit the time slot of the paging DCI, that is, Ns=2, and the terminal device determines according to i_s=floor(UE_ID/N/F) mod Ns. When i_s=0, the slot index n ₀ indicating that the DCI is pinged to the terminal device in the PF is the slot number of the SSB in which the first index is i in the PF, and the terminal device determines i_s=1. In the case of the PF, the slot index n ₀ of the paging device DCI in the PF is the slot number of the SSB in which the second index is i in the PF.

Step 305: The network device determines a time domain location where the control information is located.

Step 306: The network device determines a time slot in which the control information is located.

In this embodiment of the present application, the network device determines that the time domain location of the control information is a time domain location of the network device that can be used to send control information to the terminal device. Therefore, the network device determines the time domain location and time slot of the control information. The method is the same as that of the terminal device, that is, the step 305 is the same as the step 303, and the step 306 is the same as the step 304, and details are not described herein again.

It should be noted that, in the embodiment of the present application, the execution sequence of step 303-step 306 is not limited, that is, step 305-step 306 may be performed first, then step 303-step 304 may be performed, or step 303-step 306 may be performed simultaneously. Or step 304 is performed first, then step 303 is executed, step 306 is performed again, step 305 is performed last, or step 305 is performed first, then step 303 is performed, step 304 is performed, and step 306 is finally executed. . Steps 303 to 306 are sequentially performed in FIG. 3 as an example.

Step 307: The terminal device monitors the control information.

After the terminal device determines the time domain location and the time slot for monitoring the control information, the control information is monitored at the time domain location where the determined control information is located according to the period T of the terminal device monitoring control information, or, in the determined control The time domain location where the information is located and the monitoring control information in the time slot.

Step 308: The network device sends control information, and the terminal device receives the control information.

Taking the control information as the Paging DCI as an example, when the network device determines the time domain location for transmitting the control information, the control information is sent in the time domain location according to actual needs. For example, when the network device needs to send data to the terminal device in the idle state, or the system information changes, the network device sends the Paging DCI at the time domain location. Specifically, the network device can determine one or more time domain locations that can be used to send control information to the terminal device, and the network device can select one of the time domain locations to send control information to the terminal device.

It should be noted that, because the network device may not always send control information, and in order to ensure that the terminal device can receive the control information after the control information sent by the network device, the terminal device monitors the period T of the control information according to the terminal device. Monitoring, therefore, the period in which the terminal device monitors the control information may be different from the period in which the terminal device receives the control information. Of course, if the network device sends the control information in the period T of each monitoring control information of the terminal device, the terminal device monitors the control information. The period is the same as the period in which the terminal device receives the control information.

In the above technical solution, the network device or the terminal device determines the time domain location for transmitting or receiving the control information according to the time domain position where the synchronization signal block or the synchronization signal block measurement time is located, and realizes the reception control without the CRS. Information, and the time domain position for transmitting or receiving the control information determined in this manner is close to or the same as the time domain position of the synchronization signal block or the synchronization signal block measurement time, so that the terminal device receives the control information before receiving the control information The downlink synchronization may be performed according to the synchronization signal block. After the downlink synchronization is completed, the control information is received at the time domain location, which can ensure the effectiveness of the synchronization.
