Background

A User Equipment (UE) needs to monitor Paging downlink Control information DCI (Paging DCI) for scheduling a Paging message in both a Radio Resource Control (RRC) connected state and an idle state. For a terminal in an idle state, a Radio Access Network (RAN) may configure a Type 0PDCCH CSS common search space through a system message (e.g., MIB), so that if the radio access network does not configure another common search space for monitoring paging downlink control information for the terminal through a system information block (e.g., SIB 1), the terminal monitors the paging downlink control information through the Type 0PDCCH CSS common search space. For the connected terminal, the radio access network may allocate a dedicated search space or a common search space for the terminal to monitor the paging downlink control information.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the disclosure, as detailed in the appended claims.

In the related art, a terminal needs to monitor Paging downlink control information for scheduling a Paging message (Paging message) in both a connected state and a non-connected state (idle state/inactive state). Based on the above related art, the terminal needs to configure the search space by the radio access network (e.g., through the base station), or monitor the Paging downlink control information sent by the base station for scheduling the Paging message (Paging message) 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 monitoring the paging downlink control information for the terminal through a System Information Block (SIB), the terminal monitors the paging downlink control information based on a Type 0 physical downlink control channel common search space (Type 0PDCCH CSS). The type 0pdcch common search space is jointly determined by search space 0 (i.e., search space 0) and Control resource set0 (i.e., control resource set 0). And search space 0 is used for determining the time domain resource position, and Control resource set0 is used for determining the frequency domain resource position.

In another aspect, each cell includes one or more beams. Each beam corresponds to a type 0 physical downlink control channel common search space, and the type 0 physical downlink control channel common search space corresponding to the synchronization signal on each beam has 3 possible situations in a time-frequency resource multiplexing (multiplexing) mode. The first time-frequency resource multiplexing mode (i.e., pattern 1) at least relates to time division multiplexing, where a common search space of a type 0 physical downlink control channel corresponds to 2 slots (slot), and the second time-frequency resource multiplexing mode (i.e., pattern 2) and the third time-frequency resource multiplexing mode (i.e., pattern 3) correspond to a common search space of 1 slot.

Under the conditions of the second time-frequency resource multiplexing mode (namely, pattern 2) and the third time-frequency resource multiplexing mode (namely, pattern 3), the time-domain resource position of the search space 0 of the common search space of the type 0 physical downlink control channel is only 1 time slot, and the terminal only needs to monitor the paging downlink control information in the time slot. However, in the case of the first time-frequency resource multiplexing mode (i.e. pattern 1), the time domain resource locations of the search space 0 of the type 0pdcch common search space are distributed over a plurality of consecutive time slots (e.g. 2 time slots), so that the terminal needs to monitor the paging downlink control information in the plurality of time slots at the same time. Meanwhile, for a terminal in a connected state, the radio access network may allocate not only a common search space but also a dedicated search space dedicated to the terminal through RRC signaling, and these search spaces may all correspond to multiple timeslots. Therefore, when monitoring the paging downlink control information, the terminal may monitor the paging downlink control information unnecessarily, which may cause waste of terminal energy.

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

Fig. 1 is a diagram illustrating a communication system architecture for a network device and a terminal, according to an example embodiment. The method for monitoring paging information provided by the present disclosure may be applied to the communication system architecture diagram shown in fig. 1, where as shown in fig. 1, a base station transmits paging downlink control information. The paging downlink control information is sent by the network device in a PDCCH search space, which may adopt various multiplexing modes, and the multiplexing mode may occupy multiple time slots. By the method for monitoring the paging information provided by the disclosure, the terminal can determine at least one time slot in which the base station is likely to send the paging downlink control information in a plurality of time slots of the PDCCH search space, and monitor the paging downlink control information in the time slot. By the method, unnecessary monitoring performed by the terminal is avoided, and the energy of the terminal is saved.

Fig. 2 is a flowchart illustrating a method of listening for paging information according to an exemplary embodiment, where the method of listening for paging information is used in a terminal, as shown in fig. 2, and includes the following steps.

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

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

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

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

Therefore, in the embodiment of the present disclosure, the terminal receives indication information for a search space associated with paging downlink control information, determines at least one time slot in the indication information for monitoring the paging downlink control information, and monitors the paging downlink control information in the determined at least one time slot. For other search space time slots than the determined at least one time slot, the terminal will not listen any more. Unnecessary monitoring by the terminal is avoided, and the energy of the terminal is saved.

In one embodiment, the terminal is in an idle/inactive state, and the indication information received by the terminal for the search space associated with the paging downlink control information may be indication information in a primary system information block (MIB). Or may be indication information in a System Information Block (SIB). In other words, the terminal receives a system message (i.e., MIB message and/or SIB message) broadcast by the base station in an idle/inactive state, thereby receiving the indication information.

In the following, a specific implementation is described, in which the base station configures different initial beams based on different coverage scenarios, and transmits synchronization signals on the beams. According to the above embodiments, the multiplexing manner of the synchronization signal and the Type 0PDCCH common search space (i.e., type 0PDCCH CSS) includes 3 possible multiplexing manners. Under the condition that the search space of the paging downlink control information is Type 0PDCCH CSS and the multiplexing mode of the Type 0PDCCH CSS and the synchronous signal block is a first Type multiplexing mode (namely multiplexing pattern 1), for a synchronous signal beam, the base station selects at least one time slot on a plurality of time slots under the condition that the multiplexing mode of the Type 0PDCCH CSS and the synchronous signal block is the first Type multiplexing mode, and the time slot is used for sending the paging downlink control information. And after monitoring the synchronizing signal wave, the terminal determines at least one time slot of a Type 0PDCCH CSS for monitoring the paging downlink control information. And then, the terminal monitors the paging downlink control information in the determined at least one time slot. And no listening is performed for other time slots.

The base station may broadcast system messages on multiple SSB beams, and the terminals in the unconnected state receive the broadcast system messages (e.g., MIB) on these beams. The terminal may obtain an index (index) associated with a default common search space (Type 0PDCCH CSS) on the beam in a received message (PDCCH-ConfigSIB 1) field of the physical downlink control channel configuration in the MIB, and may obtain, based on the index (index), a resource location of the Type 0PDCCH CSS corresponding to the beam and a multiplexing manner of the Type 0PDCCH CSS and a synchronization signal block, and other related configurations.

For example, according to the protocol (TS) 38.213, in item 13 (clause 13), the definition of type 0 search space (search space 0) is that if the configuration of search space (search space 0) corresponding to index8 (index 8) in list 13-11 (Table 13-11) is selected. If the slot duration (duration) determined by the Control resource set0 (i.e., control resource set 0) is 2 symbols and the subcarrier spacing (SCS) of the type 0 physical downlink Control channel common search space corresponds to the beam transmitted by the synchronization information block, the beam transmitted by the synchronization information block (SSB) transmitted 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 the beam 1, the beam 2, the beam 3 and the beam 4 correspond to the symbol 0-1 in the SSB 0- > slot 0/1, the symbol 0-1 in the SSB1- > slot 2/3, the symbol 0-1 in the SSB 2- > slot 4/5, and the symbol 0-1 in the SSB 3- > slot 6/7, respectively.

Therefore, the indication information includes index8 (index 8), and based on index8, the configuration of the search space (search space 0) corresponding to index8, the configuration of the Control resource set (i.e., control resource set 0), and the multiplexing (multiplexing) of the search space and the synchronization signal block, for example, SSB/Type 0pdcch CSS multiplexing pattern 1, can also be obtained.

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

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

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

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

For example, the cell-associated parameters listened to by the terminal may include a cell physical layer ID of the cell listened to by the terminal and/or a system frame number of a cell broadcast listened to by the terminal. The following description will be given by taking the cell physical layer ID of the cell monitored by the terminal as an example of the parameter associated with the cell monitored by the terminal.

According to protocol convention, when a search space of paging downlink control information is a first type physical downlink control channel common search space, and a multiplexing mode of the first type physical downlink control channel common search space and a synchronization signal block is a first type multiplexing mode, a relation between a time slot of a terminal for receiving the paging downlink control information and a cell physical layer ID is i = Pcell _ ID mod N, wherein N is the number of time slots contained in the search space of the paging downlink control information, and i is an ith time slot and is used for indicating that the ith time slot of the terminal is a first time slot for monitoring the paging downlink control information. The terminal only needs to monitor the paging downlink control information in the ith time slot.

Although the above technical solution related to Type 0PDCCH CSS and corresponding SSB/Type 0PDCCH CSS multiplexing pattern 1 is exemplified, it is obvious to those skilled in the art that the above technical solution can be implemented for any Type of common search space, so that at least one time slot is determined in a plurality of time slots of the common search space for monitoring paging downlink control information. For example, when the PDCCH CSS indicated in the SIB (may be a Type 0PDCCH CSS, or other types of PDCCH CSSs such as a Type 1 PDCCH CSS and a Type 2 PDCCH CSS) also has a plurality of slots, it may be determined which one or more slots the terminal should monitor in a similar manner as described above. The one or more slots are indicated, for example, in a corresponding SIB or other signaling. These technical contents do not depart from the technical core of the present invention, and therefore these technical solutions are also included in the technical contents disclosed in the present application, and are not described again.

In still another embodiment, in the connected state, the receiving of the indication information for the search space associated with the paging downlink Control information by the terminal may also be through Radio Resource Control (RRC) signaling. Since the terminal and the base station are in a connected state, the base station may configure a dedicated search space for the terminal through radio resource control signaling, and the dedicated search space for the terminal includes at least 2 slots. The terminal may determine in which one or more of the plurality of time slots in the dedicated search space to listen for paging downlink control information via radio resource control signaling.

In one embodiment, the terminal may determine at least one time slot in the search space for listening for paging downlink control information according to predefined information. For example, the terminal may determine at least one timeslot of the paging downlink control information to be used for listening in the search space according to a manner agreed by the communication protocol in advance. For example, the terminal may directly determine, according to the specification of the communication protocol, that the 1 st slot of the multiple slots in the dedicated search space is the slot in which the base station is to transmit the paging downlink control information.

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

In another embodiment, the terminal may determine at least one time slot in the search space in which the base station transmits the paging downlink control information, using the cell-related parameters broadcast by the base station and monitored by the terminal.

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

Fig. 3 is a flowchart illustrating a method for transmitting paging information according to an exemplary embodiment, where the method for transmitting paging information is used in a network device, as shown in fig. 3, and includes the following steps.

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

At step S22, at least one slot is selected from a plurality of slots in the search space, wherein the at least one slot is used for transmitting the 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 transmitted.

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

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

Therefore, in the embodiment of the present disclosure, the base station selects at least one slot in the search space for transmitting the paging downlink control information, and transmits the indication information for the search space associated with the paging downlink control information, and transmits the paging downlink control information on the selected at least one slot.

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

In one embodiment, the terminal is in an idle/inactive state, and the indication information sent by the base station for the search space associated with the paging downlink control information may be indication information in a primary system information block (MIB). Or may be indication information in a System Information Block (SIB). In other words, in the idle/inactive state of the terminal, the base station informs the terminal of the indication information through the broadcasted system message (i.e., MIB message and/or SIB message).

In the following, a specific implementation is described, in which the base station configures different initial beams based on different coverage scenarios, and transmits synchronization signals on the beams. According to the above embodiments, the multiplexing manner of the synchronization signal and the Type 0PDCCH common search space (i.e., type 0PDCCH CSS) includes 3 possible multiplexing manners. Under the condition that the search space of the paging downlink control information is Type 0PDCCH CSS and the multiplexing mode of the Type 0PDCCH CSS and the synchronous signal block is a first Type multiplexing mode (namely multiplexing pattern 1), for a synchronous signal beam, the base station selects at least one time slot on a plurality of time slots under the condition that the multiplexing mode of the Type 0PDCCH CSS and the synchronous signal block is the first Type multiplexing mode, and the time slot is used for sending the paging downlink control information.

For example, according to the protocol (TS) 38.213, in item 13 (clause 13), the definition of type 0 search space (search space 0) is that if the configuration of search space (search space 0) corresponding to index8 (index 8) in list 13-11 (Table 13-11) is selected. If the time slot duration (duration) determined by the Control resource set0 (i.e., control resource set 0) is 2 symbols, and the sub-carrier spacing (SCS) of the type 0 physical downlink Control channel common search space corresponds to the beam transmitted by the synchronization information block, the beam 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 the beam 1, the beam 2, the beam 3 and the beam 4 correspond to the symbol 0-1 in the SSB 0- > slot 0/1, the symbol 0-1 in the SSB1- > slot 2/3, the symbol 0-1 in the SSB 2- > slot 4/5, and the symbol 0-1 in the SSB 3- > slot 6/7, respectively.

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

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

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

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

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

For example, the parameters associated with the cells listened to by the broadcasted terminal may include the cell physical layer ID of the cell listened to by the terminal and/or the system frame number of the cell broadcast listened to by the terminal. The following description will be given by taking the cell physical layer ID of the cell monitored by the terminal as an example of the parameter associated with the cell monitored by the base station sending terminal.

Although the above technical solution related to Type 0PDCCH CSS and corresponding SSB/Type 0PDCCH CSS multiplexing pattern 1 is exemplified, it is obvious to those skilled in the art that the above technical solution can be implemented for any Type of common search space, so that at least one time slot is determined in a plurality of time slots of the common search space for transmitting paging downlink control information. For example, when the PDCCH CSS indicated in the SIB (may be a Type 0PDCCH CSS, or may be another Type of PDCCH CSS such as a Type 1 PDCCH CSS or a Type 2 PDCCH CSS), and the PDCCH CSS also has a plurality of slots, it may be determined which one or more slots the base station transmits the paging downlink control information in a manner similar to the above. For example, the one or more slots are indicated in a corresponding SIB or other signaling. These technical contents do not depart from the technical core of the present invention, and therefore these technical solutions are also included in the technical contents disclosed in the present application, and are not described again here.

In still another embodiment, when the terminal is in a connected state, the base station may transmit the indication information for the search space associated with the paging downlink Control information through Radio Resource Control (RRC) signaling. Since the terminal and the base station are in a connected state, the base station may configure a dedicated search space for the terminal through radio resource control signaling, and the dedicated search space for the terminal includes at least 2 slots. The terminal may determine, through radio resource control signaling, in which one or more of the plurality of time slots in the dedicated search space to listen for paging downlink control information.

In one embodiment, the base station may select at least one slot in the search space for transmitting the paging downlink control information according to predefined information. For example, the base station may select at least one timeslot in the search space to be used for transmitting the paging downlink control information according to a manner predetermined by the communication protocol. For example, the base station may directly determine, according to the specification of the communication protocol, that the 1 st slot of the plurality of slots associated with the dedicated search space is a slot in which the base station is to transmit paging downlink control information.

In another embodiment, the base station may determine at least one slot for transmitting paging downlink control information in the search space according to radio resource control signaling. For example, the base station may indicate in radio resource control signaling which slot or slots in the dedicated search space the terminal should listen for paging downlink control information from the base station.

According to protocol convention, under the condition that a search space of paging downlink control information is a first-type physical downlink control channel common search space and a multiplexing mode of the first-type physical downlink control channel common search space and a synchronous signal block is a first-type multiplexing mode, the relation between a time slot of sending the paging downlink control information by a base station and a cell physical layer ID is i = Pcell _ ID mod N, wherein N is the number of time slots contained in the search space of the paging downlink control information, and i is an ith time slot and is used for indicating the ith time slot of a terminal to be a first time slot of sending the paging downlink control information by the base station. The terminal only needs to monitor the paging downlink control information in the ith time slot.

Based on the same conception, the embodiment of the disclosure also provides a device for monitoring paging information.
