Description

Monitoring method and device for paging, computer readable storage medium and equipment
Technical Field
The present invention relates to the field of wireless communications, and in particular, to a method and an apparatus for monitoring paging, a computer-readable storage medium, and a device.
Background
The paging message is used for indicating whether idle-state UE is called or has downlink data transmission. The eNB may send a Paging message containing Paging Record List (Paging Record List) information over the air to page the idle UE. After receiving the Paging message, the UE in idle state reads the identifier (UE-Identity) of the paged UE in the Paging record list. If the UE finds that the UE mark of the UE is consistent with a certain UE-Identity, the UE initiates an uplink access to carry out a Radio Resource Control (RRC) connection establishment process so as to receive a call, and if the UE-Identity which is consistent with the UE mark of the UE is not found, the UE discards the received Paging message and enters a dormant state.
The paging message is also used to indicate whether there is a system information update or an ETWS/CMAS reception notification. When System Information (SI) needs to be updated or ETWS/CMAS needs to be received in time, a Paging message needs to be sent to User Equipment (UE) in an IDLE (IDLE) state and User Equipment (UE) in a CONNECTED state (CONNECTED), where the Paging message indicates whether system information update occurs or not and whether ETWS/CMAS information needs to be received or not. The system information sent by the base station indicates the default paging cycle and the paging occasion number indication information. The terminal determines a Paging Occasion (PO) to receive a Paging message according to its UE ID. The terminal listens for paging messages only on its PO. If the received paging message indicates that the system information is changed, the user terminal needs to start to receive the updated system information again in the next system information modification period; and if the paging message with the changed system information is not received, confirming that the system information is not changed.
In the prior art, in the fifth Generation mobile communication technology (5th-Generation,5G) system, paging is also broadcast transmitted. In order to support terminals with different bandwidth capabilities, the 3GPP organization proposes a definition of a partial carrier Bandwidth (BWP). Meanwhile, in order to save the power consumption of the terminal, the network may configure a plurality of BWPs for the terminal according to the bandwidth reception capability of the terminal. The terminal/network can adaptively adjust the used BWP according to the service requirement and the load condition of the terminal, so as to save the power consumption of the terminal, improve the transmission rate and improve the user experience.
The system information in the NR may also be changed, and whether the system information is changed is indicated by means of a paging message. Since it is not necessary to specifically notify the UE of which system information has changed, the number of bits occupied by the indication field indicating the change of the system information in the paging message is small. In LTE, the system information change and the called UE identification are carried by the same paging message. The scheduling information of the Paging message is indicated by a Physical Downlink Control Channel (PDCCH) scrambled by a Paging-Radio Network Temporary identity (P-RNTI). The terminal needs to monitor the PDCCH scrambled by the P-RNTI on its PO, and receive a paging message transmitted on a Physical Downlink Shared Channel (PDSCH) through a scheduling resource indicated by the PDCCH.
In order to reduce the signaling overhead of the network and the power consumption of the terminal, the 3GPP working group determines that if the paging message only carries information that changes in the system information, the paging message can be directly carried through the PDCCH. Therefore, 1bit Information is needed in PDCCH Downlink Control Information (DCI) for carrying a paging message to indicate whether the DCI includes scheduling Information of the paging message.
After configuring BWPs for a terminal, a common search space for monitoring paging messages needs to be configured on each BWP in order to ensure that a UE can receive paging messages in time. According to the prior art, if system information update occurs, a base station needs to send paging DCI indicating the system information update on all POs, and a terminal monitors and receives on the PO of the terminal, so that the signaling overhead of a network and the power consumption of a user terminal are very large.

Detailed Description
In 5G systems, the paging message is also transmitted by broadcast. For the connected terminal, because only the concern about whether the system information update occurs or not, the paging indication of the system information update does not need to distinguish the terminal, therefore, if the base station sends on all POs, the terminal monitors and receives on all the POs in the system information modification period, thereby increasing the signaling overhead of the base station and also improving the power loss of the terminal.
In the current conclusion, the listening period in the common search space configured for the UE for paging is 20 slots at the maximum, which is 20ms for 15kHz SCS. In LTE the paging message period is at least 320ms based on 15kHz SCS, which is clearly not compliant with the paging requirements.
In the embodiment of the invention, a public search space monitoring period or a paging period is extended into a UE paging monitoring period by introducing a paging monitoring period extension factor and paging monitoring indication information, and a paging occasion for monitoring paging by a user terminal in the extended paging period is specified; the base station sends the configuration information to the user terminal through the broadcasted system information or through RRC dedicated signaling; the user terminal determines the period of paging monitoring and the time of paging monitoring of the user terminal according to the acquired paging monitoring configuration information and paging monitoring indication information; and the user terminal monitors the downlink control instruction carried by the physical downlink control channel scrambled by the P-RNTI according to the determined paging monitoring period and the paging monitoring opportunity.
The paging cycle is extended to prolong the period of monitoring the paging message by the terminal, so that the signaling overhead of the network can be reduced, and the power consumption of the terminal can be reduced.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
An embodiment of the present invention provides a method for paging listening, which is described in detail below with reference to fig. 1 through specific steps.
Step S101, acquiring paging monitoring configuration information sent by a base station.
In a specific implementation, the base station may send information such as Default Paging discontinuous reception configuration (Default Paging DRX) information, Paging Occasion (PO) number (nB) included in each DRX cycle, Paging listening cycle extension factor, Paging listening indication information, and the like to the user equipment through system information broadcast or through RRC dedicated signaling.
Further, the paging listening period is a period in which the ue actually needs to listen to paging, and the paging listening period extension factor is to obtain the paging listening period of the ue. The user terminal needs to multiply the paging monitoring period expansion factor and the existing paging period or paging search space monitoring period to obtain the paging monitoring period of the user terminal; the paging listening opportunity is an opportunity when the user terminal listens for a page within a paging listening period.
Further, the base station may also send information, such as a listening period of the common search space configured for paging, a paging listening period spreading factor, paging listening indication information, etc., to the user terminal through system information broadcast or through RRC dedicated signaling.
Further, the paging monitoring indication information includes indication information for indicating a paging cycle in which the paging monitoring is performed, and indication information for indicating a paging occasion in which the paging monitoring is performed is indicated by display indication or implicit default.
Further, the display indication refers to indication information configured to indicate a paging occasion where paging monitoring is located; implicit default refers to that the configuration does not need to be displayed, but a certain mode is defaulted to indicate the paging occasion where paging monitoring is located.
Step S102, the user terminal determines the paging monitoring period and the paging monitoring time of the user terminal according to the paging monitoring configuration information.
In specific implementation, the ue determines a paging monitoring period and a paging monitoring time according to the paging monitoring configuration information of the base station.
Step S103, the user terminal monitors paging according to the paging monitoring period and the paging monitoring time.
In specific implementation, the user terminal monitors a downlink control indication carried by a physical downlink control channel scrambled by a P-RNTI according to the determined paging monitoring period and the determined paging monitoring opportunity.
That is to say, in the embodiment of the present invention, the base station concentrates the user terminal on specific paging monitoring occasions to monitor paging according to the paging monitoring configuration information, and the base station sends paging only on the paging occasions, so that the signaling overhead of the base station can be reduced; the paging monitoring period of the user terminal is prolonged, so that the paging monitoring times of the user terminal can be reduced, and the power consumption of the user terminal is reduced.
For example, since the identities of the ues are different, the PO locations calculated according to the identities of the ues may be different. When there are multiple connected ues, each ue needs to monitor the PDCCH scrambled with the P-RNTI in each paging cycle to determine whether system information update occurs. If the system information is updated, the base station needs to send a system information update instruction on all POs, carries the information through the PDCCH scrambled by the P-RNTI, and indicates that the DCI is used for directly indicating that the system information is updated instead of carrying the scheduling information of paging in the corresponding DCI.
Therefore, the base station concentrates the user terminal on specific paging monitoring occasions to monitor paging through the paging monitoring configuration information, and the base station only sends the paging on the paging occasions to reduce the signaling overhead of the base station; the paging monitoring period of the user terminal is extended through configuration, so that the paging monitoring times of the user terminal can be reduced, and the power consumption of the user terminal is reduced.
The following describes a specific implementation of the method for paging listening provided in the above embodiment of the present invention.
The base station configures paging monitoring related information for the user terminal.
In the specific implementation, the base station needs to configure a paging cycle and paging occasion information for the UE, configure a paging monitoring cycle extension factor and paging monitoring indication information, extend the paging cycle to the UE paging monitoring cycle, and specify the paging occasion at which the UE monitors paging in the extended paging cycle.
In the specific implementation, when configuring the paging search space and the control resource set for the UE, the base station needs to configure a paging monitoring period extension factor and paging monitoring indication information, to extend the common search space monitoring period to the UE paging monitoring period, and to specify the paging occasion when the UE monitors the paging in the extended paging period, in addition to the monitoring period of the search space, the time slot indication information where the paging monitoring is located, and the symbol indication information in the monitoring time slot.
In a specific implementation, the base station sends the configuration information to the user terminal through broadcasted system information or through RRC dedicated signaling.
And the user terminal determines the paging monitoring period and the paging monitoring time of the user terminal according to the acquired paging monitoring configuration information and the paging monitoring indication information.
In specific implementation, the user terminal calculates and obtains the paging monitoring period of the user terminal according to the paging period and the paging monitoring period extension factor; and the user terminal determines the paging cycle of the paging monitoring and the paging occasion of the paging monitoring according to the configured paging monitoring indication information.
It can be understood that the paging listening indication information is used for indicating a paging cycle or a paging common search space listening cycle in which the paging listening of the user terminal is located and indicating a paging occasion in which the paging listening is located. The paging cycle here refers to a default paging discontinuous reception cycle indicated by the base station through system information. The paging listening period refers to a period in which the user terminal really needs to listen to paging. The paging listening period extension factor is to obtain a paging listening period of the user terminal. The user terminal needs to multiply the paging monitoring period expansion factor and the existing paging period or paging search space monitoring period to obtain the paging monitoring period of the user terminal.
Further, the paging monitoring indication information includes indication information for indicating a paging cycle or a paging common search space monitoring cycle in which paging monitoring is located, and indication information for indicating a paging occasion in which paging monitoring is located by display indication or implicit default.
Further, the display indication refers to indication information configured to indicate a paging occasion where paging monitoring is located; implicit default refers to that the configuration does not need to be displayed, but rather, one of the default modes indicates the paging occasion where paging listening is located.
And the user terminal monitors the downlink control instruction carried by the physical downlink control channel scrambled by the P-RNTI according to the determined paging monitoring period and the paging monitoring opportunity.
It can be understood that, in actual application, the system information may include other types of RRC messages besides the remaining main system information RMSI, and the RRC dedicated signaling may include other types of RRC messages besides the RRC connection reconfiguration message, which may be selected by itself according to an actual application scenario, and details are not described here.
The following describes, by way of example, a method for paging listening provided in the above embodiment of the present invention.
The base station configures default paging cycle through system information, and configures number nB of paging occasions in the default paging cycle; the base station also needs to configure a paging listening period expansion factor PagingPeriodCoeff, which can be flexibly configured into an integer value larger than 0, and the paging listening period of the user terminal determined according to the value can be shorter than the modification period or longer than the modification period; the base station configures a paging monitoring period to indicate that the paging monitoring period can be configured to be a configuration value not greater than paging period Coeff, and the configuration value is used for determining which original default paging period monitors paging in the expanded paging period; the base station configures paging listening timing indication PagingSlotCoeff configurable as an integer value not greater than nB for determining a specific paging listening timing.
In a specific implementation, the base station configures a default paging cycle to be 32 radio frames through the system information. The modification period factor is configured to be 4, i.e. the modification period is 128 radio frames. The paging occasion information is configured to 1/4 default paging cycles, i.e. there are 8 paging occasions PO in each default paging cycle. The base station obtains a paging monitoring period of the user terminal which is 2 times of the original default paging period by adding a configuration parameter paging monitoring period extension factor pageingperiodoeeff of 2, namely 64 wireless frames. If the paging listening period indicates that pagengmonitorercoff is 2 and the paging listening opportunity indicates that pagengslotcoeff is 2, it can be determined that the user terminal listens for paging at the 2 nd paging opportunity in the 2 nd original default paging period in the newly determined paging listening period.
In specific implementation, the default indication information for indicating the paging occasion where the paging monitoring is located may also be implied, that is, the paging occasion where the paging monitoring is well defined in advance may be the 1 st paging occasion in the determined default paging cycle, may also be the last paging occasion in the determined default paging cycle, and may also be any one of the paging occasions.
In another application scenario of the embodiment of the present invention, a base station configures a Monitoring period Monitoring-periodicity-PDCCH-slot of a paging search space through system information, where the value is not greater than 20 slots, the calculation is performed with a subcarrier spacing of 15kHz, that is, 20 milliseconds, and configures a Monitoring slot to indicate the Monitoring-offset-PDCCH-slot, and the value is an integer value not greater than the Monitoring period of the paging search space; the base station also needs to configure a paging listening period expansion factor PaginPeriodCoeff, which can be flexibly configured into an integer value larger than 0, and the paging listening period of the user terminal determined according to the value can be shorter than the modification period and also can be longer than the modification period; the base station configures a paging monitoring period to indicate that the paging monitor Coeff can be configured to a configuration value not greater than the paging PeriodCoeff, and is used for determining which original paging search space in the expanded paging period monitors paging; and then the specific paging Monitoring time is determined according to the paging time slot indication Monitoring-offset-PDCCH-slot indicated by the base station.
In specific implementation, the base station configures a paging search space Monitoring period Monitoring-periodicity-PDCCH-slot to be 20 slots. And configuring a Monitoring opportunity to indicate that Monitoring-offset-PDCCH-slot is 9, namely determining the 10 th slot position in the Monitoring period of the paging search space. The base station obtains 32 times of the paging monitoring period of the user terminal as the original paging search space monitoring period, namely 640 slots, by adding a configuration parameter paging monitoring period extension factor pageingperiodoeeff of 32. And if the newly-added configured paging Monitoring period indication PaginMonitorCoeff is 2, then the Monitoring-offset-PDCCH-slot can determine that the user terminal monitors paging at the 10 th paging occasion in the 3 rd original paging search space Monitoring period in the newly-determined paging Monitoring period through Monitoring slot indication Monitoring-offset-PDCCH-slot.
In specific implementation, the default indication information for indicating the paging occasion where paging monitoring is located may also be implied, that is, the paging occasion for paging monitoring may be defined in advance, may be the 1 st paging occasion in the determined paging search space monitoring period, may also be the last paging occasion in the determined paging search space monitoring period, and may also be any paging occasion.
