detailed description

Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the illustrative examples below are not intended to represent all implementations consistent with this disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as recited in the appended claims.

In the related art, a terminal needs to monitor paging downlink control information for scheduling paging messages (Paging messages) in both a connected state and a disconnected state (idle state/inactive state). Based on the above-mentioned related technologies, the terminal needs to configure the search space by the wireless access network (for example, through the base station), or monitor the paging downlink control information sent by the base station for scheduling paging messages based on the common search space.

When the terminal monitors the paging downlink control information, if the radio access network does not configure other search spaces for the terminal to monitor the paging downlink control information through the system information block (SIB), the terminal will search based on the type 0 physical downlink control channel common search space. Space (Type 0 PDCCH CSS) monitors paging downlink control information. The type 0 physical downlink control channel common search space is jointly determined by search space 0 (ie, search space 0) and control resource set 0 (ie, Control resource set0). And search space 0 is used to determine the time domain resource location, and Control resource set 0 is used to determine the frequency domain resource location.

On the other hand, each cell includes one or more beams. Each beam corresponds to a type 0 physical downlink control channel common search space, and the corresponding type 0 physical downlink control channel common search space of the synchronization signal on each beam has three possibilities in the time-frequency resource multiplexing pattern (multiplexing pattern) Case. Among them, the first time-frequency resource multiplexing mode (ie, pattern 1) involves at least time-division multiplexing, wherein the type 0 physical downlink control channel common search space corresponds to 2 time slots (slots), and the second time-frequency resource The multiplexing mode (ie, pattern 2) and the third time-frequency resource multiplexing mode (ie, pattern 3) correspond to the common search space of one time slot.

Because in the case of the second time-frequency resource multiplexing method (ie, pattern 2) and the third time-frequency resource multiplexing method (ie, pattern 3), the search space of the common search space of the type 0 physical downlink control channel is 0 There is only one time slot in the time domain resource position of , and the terminal only needs to monitor the paging downlink control information in this time slot. However, in the case of the first time-frequency resource multiplexing method (ie, pattern 1), the time-domain resource positions of search space 0 of the common search space of the type 0 physical downlink control channel are distributed in multiple consecutive time slots (for example, , 2 time slots), so the terminal needs to monitor the downlink control information of paging in multiple time slots at the same time. At the same time, for a terminal in the connected state, the radio access network may not only allocate a public search space, but also allocate a dedicated search space dedicated to the terminal through RRC signaling, and these search spaces may correspond to multiple time slots. . Therefore, unnecessary monitoring occurs when the terminal monitors the paging downlink control information, resulting in a waste of terminal energy.

In order to solve the technical problems involved in the above embodiments, the present disclosure provides a method for monitoring paging information.

According to the capacity, speed, delay and other factors of different networks, the network can be divided into 2G (English: generation) network, 3G network, 4G network or future evolution network, such as 5G network, 5G network can also be called a new wireless network ( New Radio, NR).

It should be understood that the embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the terminal.

Fig. 2 is a flowchart of a method for monitoring paging information according to an exemplary embodiment. As shown in Fig. 2 , the method for monitoring paging information is used in a terminal, and includes the following steps.

In step S11, indication information for a search space associated with the paging downlink control information is received, wherein the search space includes a plurality of time slots.

In step S12, at least one time slot among a plurality of time slots in the search space is determined, wherein at least one time slot is used for monitoring paging downlink control information in the search space.

In this embodiment of the present disclosure, the terminal may receive indication information for the search space associated with the paging downlink control information through a system message (eg, MIB or SIB, etc.) or RRC signaling. For example, in one embodiment, the indication information may indicate the resource location of the search space and/or the multiplexing manner of the search space and the synchronization signal. Optionally, the indication information may also indicate application time slot information corresponding to the search space. The application slot information indicates which slot or slots in the corresponding search space the terminal should listen to. The base station may send paging downlink control information on at least one of the one or more time slots.

The terminal may determine at least one time slot among a plurality of time slots in the search space indicated by the indication information, and the at least one time slot may be used for monitoring paging downlink control information in the search space. Wherein, at least one time slot may be a continuous time slot or a discontinuous time slot. For example, the search space includes 10 time slots, among which 5 time slots are determined for monitoring the downlink control information of paging, and these 5 time slots may be consecutive, such as 1-5 or 2-6 and so on. In another embodiment, the determined 5 time slots may be discontinuous, such as 1, 3, 5, 7, 9 or 1, 2, 4, 6, 8, etc., which are not listed one by one in the present disclosure.

Therefore, in this embodiment of the present disclosure, the terminal receives the indication information for the search space associated with the paging downlink control information, determines at least one time slot in the indication information for monitoring the paging downlink control information, and determines at least one time slot in the indication information for monitoring the paging downlink control information. Monitor paging downlink control information in one time slot. For other search space time slots other than the determined at least one time slot, the terminal will no longer monitor. Unnecessary monitoring by the terminal is avoided, and the energy of the terminal is saved.

In one embodiment, when the terminal is in an idle state/inactive state, the indication information for the search space associated with the paging downlink control information received by the terminal may be the indication information in a master system information block (MIB). It can also be indication information in a system information block (SIB). In other words, the terminal receives system messages (ie, MIB messages and/or SIB messages) broadcast by the base station in an idle state/inactive state, thereby receiving indication information.

A specific implementation manner is described below. The base station configures different initial beams based on different coverage scenarios, and sends a synchronization signal on each beam. According to the above embodiment, the multiplexing mode of the synchronization signal and the common search space of the type 0 physical downlink control channel (that is, the Type 0 PDCCH CSS) includes three possible multiplexing modes. When the search space of paging downlink control information is Type 0 PDCCH CSS, and the multiplexing mode of Type 0 PDCCH CSS and synchronization signal block is the first type multiplexing mode (ie, multiplexing pattern 1), for a synchronization signal beam, the base station In the multiplexing mode of Type 0 PDCCH CSS and synchronization signal blocks, at least one time slot is selected from multiple time slots in the first type multiplexing mode for sending paging downlink control information. After monitoring the synchronization signal beam, the terminal determines at least one time slot of the Type 0 PDCCH CSS for monitoring the paging downlink control information. Afterwards, the terminal monitors the paging downlink control information in the determined at least one time slot. For other time slots, monitoring is no longer performed.

A base station may broadcast system messages on multiple SSB beams, and terminals in a disconnected state receive broadcast system messages (eg, MIBs) on these beams. The terminal can obtain the index (index) associated with the default common search space (Type 0 PDCCH CSS) on the beam in the received physical downlink control channel configuration message (pdcch-ConfigSIB1) field in the MIB, based on the The index (index) can obtain the relevant configuration such as the resource location of the Type 0 PDCCH CSS corresponding to the beam and the multiplexing method of the Type 0 PDCCH CSS and the synchronization signal block.

For example, according to the protocol (TS) 38.213, in clause 13 (clause 13), the definition of search space (search space 0) for type 0 is, if one chooses the one in the list 13-11 (Table 13-11) The configuration of the search space (search space 0) corresponding to index 8 (index 8). If the time slot duration (duration) determined by the control resource set 0 (ie, Control resource set 0) is 2 symbols, the subcarrier spacing (subcarrier spacing) of the common search space of the type 0 physical downlink control channel corresponding to the beam transmitted by the synchronization information block spacing, SCS), the beams transmitted by the synchronization information block (SSB) sent by the cell base station may be beam 1, beam 2, beam 3 and beam 4. Therefore, the time domain positions of the search spaces corresponding to beam 1, beam 2, beam 3 and beam 4 correspond to symbols 0-1 in SSB 0->slot 0/1, symbols 0-1 in SSB1->slot 2/3, Symbols 0-1 in SSB 2->slot 4/5, symbols 0-1 in SSB 3->slot 6/7.

Therefore, if the indication information includes index 8 (index8), then based on index 8, the configuration of the search space (search space 0) corresponding to index8, the configuration of the control resource set (ie, Control resource set 0), and the search space and the The multiplexing pattern of the synchronization signal block, for example, the multiplexing pattern is SSB/Type 0PDCCH CSS multiplexing pattern 1.

In this way, index8 indicates the common search space of Type 0 PDCCH CSS corresponding to the SSB beam, and for this common search space, the multiplexing method with SSB is SSB/Type 0 PDCCH CSS multiplexing pattern 1. In this case, the search space has two slots. The terminal may determine that the base station will transmit the paging downlink control information on a specific time slot of the two time slots. Therefore, the terminal determines one of the two time slots that can be used for monitoring the downlink control information for paging. When the base station does not configure other search spaces for monitoring the paging downlink control information for the terminal through the subsequent system information block (SIB), the terminal will use the type 0 physical downlink control channel common search space (Type 0 physical downlink control channel) configured in the MIB above. 0 PDCCH CSS) to monitor paging downlink control information. At this time, the terminal will monitor the paging downlink control information in the determined time slot based on the Type 0 PDCCH CSS.

In one embodiment, the terminal may determine at least one time slot in the search space for monitoring downlink control information of paging according to predefined information. For example, the terminal may determine at least one time slot in the search space to be used for monitoring the downlink control information of paging in a manner pre-agreed by the communication protocol. For example, the terminal may directly determine, according to the provisions of the communication protocol, that the first time slot in the two time slots corresponding to SSB/Type 0 PDCCH CSS multiplexing pattern 1 is the time slot in which the base station is to send paging downlink control information.

In another implementation manner, the terminal may determine at least one time slot in the search space where the base station sends the paging downlink control information according to the system (MIB and/or SIB) message.

For example, as described above, the index in pdcch-ConfigSIB1 in the MIB may indicate the resource location of the common search space and/or the multiplexing manner of the common search space and the synchronization signal. According to an embodiment of the present invention, a corresponding physical meaning may be added to the index value. For example, the value of index may be set to indicate the resource location of the Type 0 PDCCH CSS and the multiplexing mode of the Type 0 PDCCH CSS and the synchronization signal, and also indicate the application time slot information of the Type 0 PDCCH CSS. The application slot information indicates which slot or slots in the corresponding search space the terminal should listen to. The base station may send paging downlink control information on at least one of the one or more time slots.

In another embodiment, the terminal may determine at least one time slot in which the base station sends the downlink control information for paging in the search space by using parameters broadcast by the base station associated with the cell monitored by the terminal.

For example, the parameters associated with the cell monitored by the terminal may include the cell physical layer ID of the cell monitored by the terminal and/or the system frame number broadcast by the cell monitored by the terminal. The following embodiments of the present disclosure will be described by taking as an example that the parameter associated with the cell monitored by the terminal is the cell physical layer ID of the cell monitored by the terminal.

According to the agreement, the search space for paging downlink control information is the first type of physical downlink control channel common search space, and the multiplexing method of the first type of physical downlink control channel common search space and synchronization signal blocks is the first type In the multiplexing mode, the relationship between the time slot in which the terminal receives the paging downlink control information and the cell physical layer ID is, i=Pcell_ID mod N, where N is the number of time slots included in the search space of the paging downlink control information, i is the ith time slot, and is used to indicate that the ith time slot of the terminal is the first time slot for monitoring the downlink control information of paging. The terminal only needs to monitor the paging downlink control information in the ith time slot.

Although the technical solutions related to Type 0 PDCCH CSS and the corresponding SSB/Type 0 PDCCH CSS multiplexing pattern 1 are used as examples above, for those skilled in the art, the above technical solutions can be implemented for any type of public search space, so that the At least one time slot is determined among multiple time slots in the common search space for monitoring the downlink control information of paging. For example, for the PDCCH CSS indicated in the SIB (which may be Type 0 PDCCH CSS, or other types of PDCCH CSS such as Type 1 PDCCH CSS, Type 2 PDCCH CSS, etc.), when the PDCCH CSS also has multiple time slots, It may also be determined in a similar manner as above which one or more of the plurality of time slots the terminal should listen to. For example, the one or more time slots are indicated in the corresponding SIB or other signaling. These technical contents do not deviate from the technical core of the present invention, so these technical solutions are also included in the technical contents disclosed in this application, and will not be repeated here.

In yet another embodiment, in the connected state, the terminal receiving the indication information for the search space associated with the paging downlink control information may also be through radio resource control (Radio Resource Control, RRC) signaling. Since the terminal and the base station are in a connected state, the base station can configure a dedicated search space for the terminal through radio resource control signaling, and the dedicated search space configured for the terminal includes at least two time slots. The terminal may determine, through radio resource control signaling, in which one or more time slots among the multiple time slots in the dedicated search space, the downlink control information for paging is monitored.

In one embodiment, the terminal may determine at least one time slot in the search space for monitoring downlink control information of paging according to predefined information. For example, the terminal may determine at least one time slot in the search space to be used for monitoring the downlink control information of paging in a manner pre-agreed by the communication protocol. For example, the terminal may directly determine, according to the provisions of the communication protocol, the first time slot among the multiple time slots in the dedicated search space as the time slot for the base station to send the downlink control information for paging.

In another implementation manner, the terminal may determine, according to the radio resource control signaling, at least one time slot in which the base station sends the paging downlink control information in the search space. For example, the base station may indicate in the RRC signaling which one or more time slots in the dedicated search space the terminal should use to monitor the paging downlink control information from the base station.

For example, the parameters associated with the cell monitored by the terminal may include the cell physical layer ID of the cell monitored by the terminal and/or the system frame number broadcast by the cell monitored by the terminal. The following embodiments of the present disclosure will be described by taking an example that the parameter associated with the cell monitored by the terminal is the cell physical layer ID of the cell monitored by the terminal.

Based on the same concept, an embodiment of the present disclosure also provides a method for sending paging information.

Fig. 3 is a flowchart of a method for sending paging information according to an exemplary embodiment. As shown in Fig. 3 , the method for sending paging information is used in a network device and includes the following steps.

In step S21, a search space associated with the paging downlink control information is determined, wherein the search space includes a plurality of time slots.

In step S22, at least one time slot is selected from a plurality of time slots in the search space, wherein at least one time slot is used for transmitting paging downlink control information in the search space.

In step S23, indication information for the search space associated with the paging downlink control information is sent.

In this embodiment of the present disclosure, the network device may also be referred to as a base station. The base station may send the indication information for the search space associated with the paging downlink control information through system messages (eg, MIB or SIB, etc.) or RRC signaling. For example, in one embodiment, the indication information may indicate the resource location of the search space and/or the multiplexing manner of the search space and the synchronization signal. Optionally, the indication information may also indicate application time slot information corresponding to the search space. The application slot information indicates which slot or slots in the corresponding search space the terminal should listen to. The base station may send paging downlink control information on at least one of the one or more time slots.

The base station may select at least one time slot from the plurality of time slots in the search space indicated by the indication information, and the at least one time slot may be used for sending paging downlink control information in the search space. Wherein, at least one time slot may be a continuous time slot or a discontinuous time slot. For example, the search space includes 10 time slots, among which 5 time slots are determined for monitoring the paging downlink control information, and these 5 time slots may be consecutive, such as 1-5 or 2-6 and so on. In another embodiment, the determined 5 time slots may be discontinuous, such as 1, 3, 5, 7, 9 or 1, 2, 4, 6, 8, etc., which are not listed one by one in the present disclosure.

Therefore, in this embodiment of the present disclosure, the base station selects at least one time slot in the search space for sending paging downlink control information, and sends indication information for the search space associated with the paging downlink control information, and The paging downlink control information is sent on at least one of the selected time slots.

In one embodiment, sending the paging downlink control information on the selected at least one time slot may include: sending the paging downlink control information on each of the selected at least one time slot; The paging downlink control information is sent on a part of the at least one time slot of the selected time slot; or the paging downlink control information is sent on a time slot in the selected at least one time slot.

In an embodiment, when the terminal is in an idle state/inactive state, the indication information for the search space associated with the paging downlink control information sent by the base station may be the indication information in a master system information block (MIB). It can also be indication information in a system information block (SIB). In other words, when the terminal is in an idle state/inactive state, the base station informs the terminal of the indication information through broadcast system messages (ie, MIB messages and/or SIB messages).

A specific implementation manner is described below. The base station configures different initial beams based on different coverage scenarios, and sends a synchronization signal on each beam. According to the above embodiment, the multiplexing mode of the synchronization signal and the common search space of the type 0 physical downlink control channel (that is, the Type 0 PDCCH CSS) includes three possible multiplexing modes. When the search space of paging downlink control information is Type 0 PDCCH CSS, and the multiplexing mode of Type 0 PDCCH CSS and synchronization signal block is the first type multiplexing mode (ie, multiplexing pattern 1), for a synchronization signal beam, the base station In the multiplexing mode of Type 0 PDCCH CSS and synchronization signal blocks, at least one time slot is selected from multiple time slots in the first type multiplexing mode for sending paging downlink control information.

In this way, index8 indicates the common search space of Type 0 PDCCH CSS corresponding to the SSB beam, and for this common search space, the multiplexing method with SSB is SSB/Type 0 PDCCH CSS multiplexing pattern 1. In this case, the search space has two slots. The base station will send paging downlink control information on a specific time slot of the two time slots. Therefore, the terminal determines one of the two time slots that can be used for monitoring the downlink control information for paging. When the base station does not configure other search spaces for monitoring the paging downlink control information for the terminal through the subsequent system information block (SIB), the terminal will use the type 0 physical downlink control channel common search space (Type 0 physical downlink control channel) configured in the MIB above. 0 PDCCH CSS) to monitor paging downlink control information. At this time, the terminal will monitor the paging downlink control information in the determined time slot based on the Type 0 PDCCH CSS.

In one embodiment, the base station may select at least one time slot in the search space for sending paging downlink control information according to predefined information. For example, the base station may select at least one time slot in the search space to be used for transmitting the paging downlink control information in a manner pre-agreed by the communication protocol. For example, the base station may directly determine, according to the provisions of the communication protocol, that the first time slot in the two time slots corresponding to SSB/Type 0 PDCCH CSS multiplexing pattern 1 is the time slot in which the base station is to send paging downlink control information.

In another embodiment, the base station may select at least one time slot in the search space for transmitting the paging downlink control information according to the system (MIB and/or SIB) message.

In another embodiment, the base station may broadcast parameters associated with the cell monitored by the terminal, and inform the terminal of at least one time slot in the search space where the base station sends paging downlink control information.

For example, the broadcasted parameters associated with the cell monitored by the terminal may include the cell physical layer ID of the cell monitored by the terminal and/or the system frame number broadcast by the cell monitored by the terminal. The following embodiments of the present disclosure will be described by taking as an example that the parameter associated with the cell monitored by the terminal is sent by the base station as the cell physical layer ID of the cell monitored by the terminal.

Although the technical solutions related to Type 0 PDCCH CSS and the corresponding SSB/Type 0 PDCCH CSS multiplexing pattern 1 are used as examples above, for those skilled in the art, the above technical solutions can be implemented for any type of public search space, so that the At least one time slot in the multiple time slots in the common search space is determined for transmitting paging downlink control information. For example, for the PDCCH CSS indicated in the SIB (which may be Type 0 PDCCH CSS, or other types of PDCCH CSS such as Type 1 PDCCH CSS, Type 2 PDCCH CSS, etc.), when the PDCCH CSS also has multiple time slots, In a similar manner to the above, it is also possible to determine which one or more time slots in the plurality of time slots the base station transmits the paging downlink control information. For example, the one or more time slots are indicated in the corresponding SIB or other signaling. These technical contents do not deviate from the technical core of the present invention, so these technical solutions are also included in the technical contents disclosed in this application, and will not be repeated here.

In yet another embodiment, when the terminal is in a connected state, the base station sends the indication information for the search space associated with the paging downlink control information may also be through radio resource control (Radio Resource Control, RRC) signaling. Since the terminal and the base station are in a connected state, the base station can configure a dedicated search space for the terminal through radio resource control signaling, and the dedicated search space configured for the terminal includes at least two time slots. The terminal may determine, through radio resource control signaling, in which one or more time slots among the multiple time slots in the dedicated search space, the downlink control information for paging is monitored.

In one embodiment, the base station may select at least one time slot in the search space for sending paging downlink control information according to predefined information. For example, the base station may select at least one time slot in the search space to be used for transmitting the paging downlink control information in a manner pre-agreed by the communication protocol. For example, the base station may directly determine, according to the provisions of the communication protocol, the first time slot among the multiple time slots in the dedicated search space as the time slot for the base station to send the paging downlink control information.

In another implementation manner, the base station may determine at least one time slot in the search space for sending downlink control information for paging according to radio resource control signaling. For example, the base station may indicate in the radio resource control signaling which one or more time slots in the dedicated search space the terminal should use to monitor the paging downlink control information from the base station.

In another embodiment, the base station may broadcast parameters associated with the cell monitored by the terminal, and inform the terminal of the base station to send at least one time slot of the downlink control information for paging in the search space.

According to the agreement, the search space for paging downlink control information is the first type of physical downlink control channel common search space, and the multiplexing method of the first type of physical downlink control channel common search space and synchronization signal blocks is the first type In the multiplexing mode, the relationship between the time slot in which the base station sends the paging downlink control information and the cell physical layer ID is, i=Pcell_ID mod N, where N is the number of time slots included in the search space of the paging downlink control information, i is the ith time slot, and is used to indicate that the ith time slot of the terminal is the first time slot for the base station to send the paging downlink control information. The terminal only needs to monitor the paging downlink control information in the ith time slot.
