This application claims a priority to Chinese Patent Application No. 201710920159.9 filed on Sep. 30, 2017, the disclosure of which is incorporated in its entirety by reference herein.
The present disclosure relates to the technical field of communications, and in particular to a paging method, a terminal and a network-side device.
In a Long Term Evolution (LTE) system in related art, in a case that a network side is going to perform data transmission with a user equipment (UE) in an idle mode, a network-side device needs to notify the UE via paging. In this case, the UE shall monitor a paging message to complete subsequent responses. However, if the UE in an idle mode keeps monitoring a paging message, it may waste a great deal of power of the UE. Therefore, in order to save power consumption of the UE, a Discontinuous Reception (DRX) period is introduced in the LTE system. The UE monitors a physical downlink control channel (PDCCH) only at a position corresponding to a paging frame (PF) and a paging occasion (PO) calculated according to UE_ID, thereby receiving a paging message on a resource indicated by PDCCH information.
Since a network side does not know a specific location of a UE in an idle mode, the network side may transmit a paging message to the UE through all base stations in a tracking area (TA), when the UE needs to be paged, which causes a waste of network resources.
In a first aspect, a paging method is provided according to an embodiment of the present disclosure, which is applied to a terminal. The method includes:

In order to explain technical solutions of embodiments of the present disclosure more clearly, drawings used in the embodiments of the present disclosure will be briefly illustrated below. Obviously, the drawings in the following description are only some embodiments of the present disclosure. Based on these drawings, those skilled in the art can also obtain other drawings without paying creative effort.
Reference is made to
Step 101 includes: receiving pre-indication information transmitted by a network-side device.
The pre-indication information is transmitted by the network-side device in advance before initiating a paging, which is used to indicate a terminal and/or a terminal group to be paged. When the pre-indication information indicates a certain terminal and/or a certain terminal group that is to be paged, an identifier (ID) of the terminal and/or an ID of the terminal group may be carried in the pre-indication information. That is, in a case that the pre-indication information carries an ID of a certain terminal and/or an ID of a certain terminal group, the pre-indication information indicates that the certain terminal and/or the certain terminal group is to be paged.
Specifically, the pre-indication information may be at least one of the following information: paging indication information, prior indication information, a wake-up signaling, a go-to-sleep signaling, or the like.
Step 102 includes: transmitting an uplink signal to the network-side device in a case that the pre-indication information indicates that the terminal is to be paged.
The uplink signal transmitted by the terminal is a response to the received pre-indication information. That is, in a case that a to-be-paged terminal and/or a to-be-paged terminal group indicated by the pre-indication information includes a terminal that has received the pre-indication information, the terminal that has received the pre-indication information may transmit an uplink signal to the network-side device. For example, if pre-indication information A transmitted by a base station indicates that terminal 1, terminal 2, terminal 3, and terminal 4 are to be paged, terminal 2 transmits an uplink signal to the base station when receiving pre-indication information A, as pre-indication information A indicates that terminal 2 is to be paged; while terminal 5 may not transmit an uplink signal to the base station when receiving pre-indication information A. Alternatively, if pre-indication information A also indicates that terminal group 1 and terminal group 2 (including terminal 5) are to be paged, terminal 5 may transmit an uplink signal to the base station when receiving pre-indication information A, as pre-indication information A indicates that terminal 5 is to be paged.
In an embodiment of the present disclosure, the uplink signal may be at least one of the following signals: a sequence signal, a predefined indication signal, an uplink reference signal, an uplink signal carried in a physical uplink control channel (PUCCH), or an uplink signal carried in a physical uplink sharing channel (PUSCH).
The sequence signal may be a preamble sequence signal or a newly designed sequence signal. The uplink reference signal may be an uplink reference signal in related art. The uplink signal carried in PUCCH or PUSCH may be transmitted, for example, through an Msg3 message or a request message for radio resource control (RRC) connection.
Further, in a case that the uplink signal is a preamble sequence signal, the network-side device may configure a dedicated preamble sequence for the terminal through system information and/or a dedicated RRC signaling, before transmitting an uplink signal. It should be noted that the network side may configure the preamble sequence for the terminal before transmitting the pre-indication information, or may configure the preamble sequence after transmitting the pre-indication information and before the terminal transmits the uplink signal, or may also configure the preamble sequence when transmitting the pre-indication information, and notify the terminal of the configuration through pre-indication information.
In addition, for transmitting an uplink signal, the terminal may transmit the uplink signal periodically; or the terminal may transmit the uplink signal after receiving the pre-indication information, and the pre-indication information carries an ID of the terminal and/or an ID of a terminal group where the terminal is located; or the terminal may transmit the uplink signal in a case that the pre-indication information indicates that the terminal is to be paged.
Step 103 includes: monitoring a paging of the terminal by the network-side device.
In monitoring the paging of the terminal by the network-side device, the terminal may receive a paging message transmitted by the network-side device, or may receive physical downlink control channel (PDCCH) information transmitted by the network-side device in a case that downlink information transmitted by the network-side device only contains the PDCCH information, and the PDCCH information implicitly indicates the paging to the terminal by the network-side device. In such manner, the paging of the terminal is implicitly indicated by the PDCCH information, which can avoid transmitting an additional paging message for paging, thereby saving resources and power consumption of a terminal.
The paging method according to the embodiment of the present disclosure includes: receiving pre-indication information transmitted by a network-side device; transmitting an uplink signal to the network-side device in response to the pre-indication information indicating that the terminal is to be paged; and monitoring a paging of the terminal by the network-side device, thereby achieving a feedback-based paging method. In such manner, a terminal and/or a terminal group to be paged can be indicated by the pre-indication information before paging, and after the terminal receives the pre-indication information and provides feedback, the network side can determine a paging range based on the feedback from the terminal, thus the network side does not need to perform paging in all the original tracking area, and network resources are saved. Moreover, the network side can further determine a resource location of paging based on a resource indicated by the feedback from the terminal, thereby saving beam resources for the network side to page.
In an embodiment of the present disclosure, the uplink signal transmitted by the terminal may implicitly or explicitly carry at least one of a terminal ID of the terminal or a terminal group ID of the terminal. Specifically, in a case that the uplink signal implicitly carries at least one of the terminal ID of the terminal or the terminal group ID of the terminal, at least one of the terminal ID of the terminal or the terminal group ID of the terminal is determined based on at least one of a preamble sequence, information about a beam, a time-domain resource or a frequency-domain resource that is used by the uplink signal; or in a case that the uplink signal explicitly carries at least one of the terminal ID of the terminal or the terminal group ID of the terminal, the uplink signal directly carries at least one of the terminal ID of the terminal or the terminal group ID of the terminal.
It should be noted that the terminal ID carried in the uplink signal may be complete identification information UE_ID of the terminal or a part of the UE_ID, and the UE_ID includes at least one of the following information: an international mobile subscriber identification number (IMSI), a system architecture evolution temporary mobile station identifier (S-TMSI), a temporary mobile subscriber identity (TMSI), a packet temporary mobile subscriber identity (P-TMSI), a configured ID, or a resume ID.
In an embodiment of the present disclosure, in transmitting the uplink signal to the network-side device, the terminal may transmit the uplink signal according to a variety of different resources. The resource may be at least one of a time-domain resource, a frequency-domain resource, or a beam resource. Specifically, step 102 may include:
transmitting, by the terminal, the uplink signal to the network-side device according to a reserved resource or a predefined resource, where the reserved resource is, for example, a resource reserved for the terminal in advance, and the predefined resource is, for example, a resource predefined through a technical specification; or
transmitting, by the terminal, the uplink signal to the network-side device according to a resource indicated implicitly or explicitly in the pre-indication information, where in a case that the pre-indication information explicitly indicates the resource, the pre-indication information may directly carry indication information indicating a resource where the terminal is to transmit the uplink signal, or in a case that the pre-indication information implicitly indicates the resource, the resource implicitly indicated by the pre-indication information may be a time-domain resource, and/or a frequency-domain resource, and/or a beam resource corresponding to a resource, which is used by the pre-indication information; or
transmitting, by the terminal, the uplink signal to the network-side device according to a resource indicated by downlink control information corresponding to the pre-indication information; or
transmitting, by the terminal, the uplink signal to the network-side device according to an uplink resource corresponding to a predetermined synchronization signal block (SSB), where the predetermined SSB may be one of following SSBs: a current optimal SSB, an SSB whose signal quality is higher than a predetermined threshold, an SSB closest to the pre-indication information than other SSBs, or an SSB that is closest to the pre-indication information and has a signal quality higher than a predetermined threshold; or
transmitting, by the terminal, the uplink signal to the network-side device according to a configured random access resource; or
transmitting, by the terminal, the uplink signal to the network-side device according to a resource corresponding to at least one of the terminal ID of the terminal or the terminal group ID of the terminal.
Further, in an embodiment of the present disclosure, the uplink signal may carry indication information that is used to indicate a resource where the network-side device is to page, and/or indication information that is used to indicate a resource where the terminal monitors the paging from the network-side device.
In an embodiment of the present disclosure, when the terminal monitors the paging from the network-side device, the terminal may monitor it on a variety of different resources. It should be noted that the resources herein mainly refer to beam resources, and a location of a time-domain resource may be calculated based on PO and PF. Specifically, step 103 may include:
monitoring, by the terminal, the paging of the terminal by the network-side device on a resource indicated by indication information carried in the uplink signal; or
monitoring, by the terminal, the paging of the terminal by the network-side device on a resource associated with a resource where the uplink signal is transmitted; or
monitoring, by the terminal, the paging of the terminal by the network-side device on a configured resource; or
monitoring, by the terminal, the paging of the terminal by the network-side device on a resource corresponding to at least one of a terminal identifier (ID) of the terminal or a terminal group ID of the terminal.
