Description

Determination method, terminal equipment and network equipment
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a determination method, a terminal device, and a network device.
Background
In a New Radio (NR) system, a Network device may indicate system information update through a Paging Physical Downlink Control Channel (Paging PDCCH) (i.e., a PDCCH scrambled by a Paging-Radio Network temporary Identity (P-RNTI)), and if a Network side indicates system information update, a User Equipment (UE) needs to receive New system information in a modification period (modification period).
Generally, paging involves two main roles: 1) Paging idle UE; 2) Indicating a system information update. If a user is paged, the PDSCH scheduled by the Paging PDCCH contains the ID of the paged UE; if no user is paged and the system information needs to be updated, the Paging PDCCH does not indicate the transmission of the PDSCH, i.e. the resources of the PDSCH for transmitting the Paging are not used.
Meanwhile, in the unlicensed frequency band of NR, before the terminal device or the network device sends information, it needs to perform Clear Channel Association (CCA)/extended Clear Channel association (eCCA) to monitor a Channel, and if the monitoring result is idle, it indicates that the Channel is available. That is, when the network side indicates updating of the system information, channel sensing is required, and only when an idle channel is acquired, transmission of the system information is performed.
However, since multiple transmission nodes may share the same unlicensed frequency band, when a channel is available, a signal transmission opportunity on the network side is likely to be missed, so that the network device may not send a signal, and a receiving end may not normally receive a signal transmitted by the network side.
Thus, when the network side instructs to update the system information, if the channel sensing result is null but no user is paged, idle resources are wasted.

Fig. 2 shows a schematic flow chart of a determination method provided in an embodiment of the present invention, and as shown in fig. 2, the determination method provided in the embodiment of the present invention may specifically include the following steps:
step 201: and the network equipment sends the first PDCCH to the terminal equipment.
Step 202: and the network equipment sends the second PDCCH to the terminal equipment.
In this embodiment of the present invention, the first PDCCH is a PDCCH scrambled by a P-RNTI (i.e., a Paging PDCCH), and the network device may indicate system information update through the first PDCCH.
In this embodiment of the present invention, the second PDCCH is a PDCCH scrambled with SI-RNTI, wherein the system information is mainly transmitted through PDSCH (i.e. herein, target PDSCH) resources scheduled by the second PDCCH; the second PDCCH is used to instruct the terminal device to determine whether the target PDSCH includes updated system information according to the second PDCCH.
Step 203: and the terminal equipment monitors the second PDCCH under the condition of monitoring the first PDCCH.
The network device in the embodiment of the present invention may be a network device in the communication system shown in fig. 1, for example, a base station; the terminal device in the embodiment of the present invention may be a terminal device in the communication system shown in fig. 1.
In one example, the network device transmits a first PDCCH and a second PDCCH on the unlicensed frequency band, and correspondingly, the terminal device monitors the second PDCCH in the case of monitoring the first PDCCH on the unlicensed frequency band.
In the embodiment of the present invention, when the terminal device executes step 203, two ways may be selected to execute:
in the method 1, the first PDCCH is monitored and the second PDCCH is monitored all the time.
In the mode 2, while monitoring the PDCCH scrambled by the P-RNTI, if the first PDCCH indicates system information update, the terminal device may determine a monitoring opportunity or a search space for monitoring the second PDCCH according to Paging, and monitor the second PDCCH at the monitoring opportunity or the search space.
Optionally, in the embodiment of the present invention, the step 203 may be implemented by at least two implementation manners:
a first possible implementation:
illustratively, in this implementation manner, the step 203 specifically includes the following steps:
step A: and the terminal equipment monitors a second PDCCH according to the first PDCCH under the condition of monitoring the first PDCCH.
In one example, the first PDCCH is used to indicate a monitoring time of the second PDCCH. Illustratively, the first PDCCH is specifically used for indicating at least one of the following: monitoring the monitoring time of the second PDCCH, monitoring the time frequency offset information of the monitoring time of the second PDCCH and the current time, monitoring the monitoring time window length of the second PDCCH and the like. Illustratively, the Paging DCI in the first PDCCH is used to indicate the listening time information of the second PDCCH.
In an example, the first PDCCH is used to instruct the terminal device to monitor the second PDCCH, that is, the terminal device monitors the second PDCCH according to the instruction of the first PDCCH.
A second possible implementation:
illustratively, in this implementation manner, the step 203 specifically includes the following steps:
and B: and the terminal equipment monitors a second PDCCH in the same change period under the condition of monitoring the first PDCCH.
For example, the terminal device monitors the first PDCCH and the second PDCCH in the same change period, so that the terminal device can consider to transmit the updated system information in time after monitoring the second PDCCH, without waiting for the next change period.
A third possible implementation:
illustratively, in this implementation manner, the step 203 specifically includes the following steps:
and C: and the terminal equipment monitors a second PDCCH in the target search space under the condition of monitoring the first PDCCH.
In this implementation, the terminal device monitors the second PDCCH in the target search space only when the first PDCCH is used to indicate system information update, otherwise, the terminal device does not monitor the second PDCCH.
In the embodiment of the present invention, the target search space may be one search space or a plurality of search spaces, which is not limited in the present invention; the target search space may be predefined, may be specified by a protocol, or may be configured by a network device to a terminal device, which is not limited in the present invention.
Example 1:
exemplarily, in combination with the step C, the step 204 specifically includes the following steps:
step C1: and if the terminal equipment monitors the second PDCCH, determining that the target PDSCH contains updated system information.
For example, after detecting the second PDCCH in the target search space, the terminal device may determine that the target PDSCH includes updated system information.
Example 2:
for example, when the target search space is at least one search space (i.e., a Paging search space of a Paging Occasion) corresponding to a Paging Occasion (Paging Occasion), the step C specifically includes the following steps:
and step C2: and under the condition that the terminal equipment monitors the first PDCCH in the target search space, monitoring a second PDCCH in the target search space.
Illustratively, the terminal device monitors the first PDCCH and the second PDCCH in the same search space, and if the second PDCCH is detected, determines that the target PDSCH scheduled by the second PDCCH includes updated system information.
Example 3:
illustratively, the step C specifically includes the following steps:
step C31: the terminal device receives the first indication information from the network device.
Correspondingly, the opposite terminal network equipment sends the first indication information to the terminal equipment.
Step C32: and the terminal equipment monitors a second PDCCH in the target search space under the condition of monitoring the first PDCCH according to the first indication information.
The first indication information is transmitted in a first PDCCH, and the first indication information is used for indicating that monitoring of a second PDCCH is performed in a target search space. For example, the target search space may be: predefined, or, the network device is configured through system information or RRC signaling.
It should be noted that the target search space is different from the conventional search spaces ib1 and the search spaces OSI, and only when the first PDCCH indicates system information update, the terminal device monitors the second PDCCH in the target search space, otherwise, the terminal device does not monitor the second PDCCH. That is, when the first PDCCH indicates system information update, the network device transmits first indication information to the terminal device in the first PDCCH, and after receiving the first indication information, the terminal device activates the target search space and monitors the second PDCCH in the target search space. Generally, after the terminal device completes receiving the updated system information, the target search space is deactivated, that is, the terminal device does not monitor the second PDCCH any more.
It should be noted that the terminal device may be implemented based on any one of the above-mentioned implementations, or may be implemented based on a combination of multiple implementations, which is not limited by the present invention.
Optionally, in the embodiment of the present invention, the network device may indicate, in the system information, whether the terminal device executes a process of enhancing a system information transmission instruction (that is, the determination method provided in the embodiment of the present invention).
Illustratively, the step 203 specifically includes the following steps:
step 203b1: the terminal device receives the third indication information from the network device.
Step 203b2: and the terminal equipment monitors the second PDCCH according to the third indication information under the condition of monitoring the first PDCCH. The third indication information is used for indicating the terminal device to monitor the second PDCCH when monitoring the first PDCCH.
In one example, the third indication information may be carried in system information.
Illustratively, after receiving the first indication information, the network device monitors the second PDCCH under the condition of monitoring the first PDCCH, otherwise, the terminal device does not monitor the second PDCCH while monitoring the first PDCCH until the next change period, and then monitors the second PDCCH, and receives the system information in the target PDSCH scheduled by the second PDCCH.
Step 204: and the terminal equipment determines whether the target PDSCH contains updated system information or not according to the second PDCCH.
In an embodiment of the present invention, the target PDSCH is a PDSCH scheduled by the second PDCCH.
In the embodiment of the present invention, after monitoring the second PDCCH, the terminal device may perform reception of the SI-PDSCH (i.e., the target PDSCH) according to the scheduling information in the second PDCCH, that is, in a case that the network side indicates updating of the system information, and in a case that the channel sensing result is empty and no user is paged, since the Paging PDCCH does not indicate transmission of the PDSCH scheduled by the Paging PDCCH, the terminal device may perform transmission of the updated system information on the currently obtained channel resource, that is, transmit the SI-PDSCH on the currently obtained channel resource.
For example, after receiving the SI-PDSCH, the terminal device may determine whether the SI-PDSCH includes updated system information based on the second PDCCH, and if the SI-PDSCH includes updated system information, may select to immediately transmit the updated system information, so as to shorten transmission delay of the system information, that is, the terminal device decodes the target PDSCH and receives the updated system information included in the target PDSCH; if the updated system information is not included, the terminal device does not decode the target PDSCH.
Optionally, in an embodiment of the present invention, the second PDCCH includes second indication information, where the second indication information is used to indicate whether the target PDSCH includes updated system information. The terminal device may directly determine whether the target PDSCH contains updated system information based on the indication information contained in the second PDCCH.
In an example, with reference to step C, after the terminal device monitors the second PDCCH in the target search space, since the monitored target PDSCH scheduled by the second PDCCH may include the system information valid in the current modification period or may include updated system information, the terminal device may determine whether the target PDSCH scheduled by the second PDCCH includes updated system information according to an indication of second indication information included in the second PDCCH.
Further optionally, in an embodiment of the present invention, the target DCI in the second PDCCH includes the second indication information, where the target DCI is used to schedule the target PDSCH.
Illustratively, for the terminal device residing in the cell, the system information of the current change cycle has been stored, if the Paging indicates system information update, the terminal device performs second PDCCH detection, if the second PDCCH is detected and the target DCI in the second PDCCH includes second indication information for indicating that the system information included in the target PDSCH is the updated system information, then performs target PDSCH reception, otherwise, it regards that the system information is already received, and then discards the target PDSCH reception.
In an example, when the network device indicates that the terminal device needs to update the system information through Paging, 1bit (bit) (e.g., 1 bit) indication information may be added to a target DCI (i.e., DCI of a scheduling target PDSCH) in the second PDCCH to indicate whether the system information included in the target PDSCH is updated system information that is sent in advance, that is, updated system information that becomes effective in a next change period.
For example, the 1-bit indication information may be in the form of a New Data Indicator (NDI) transmitted using 1 bit. Specifically, if the 1-bit indication information in the target DCI is different from the 1-bit indication information corresponding to the current system information when received, the transmitted system information is considered to be updated system information. For example, if the currently valid system information is received, the NDI =0 corresponding to the target DCI in the second PDCCH, and after the Paging indicates that the system information is updated, the NDI =1 corresponding to the target DCI in the second PDCCH, or the NDI =1 corresponding to the updated system information that is sent in advance, and the corresponding NDI in the SI-PDCCH that is normally sent in the next change period is 0, that is, the system information that is not currently valid in the change period is changed, and the corresponding NDI in the target DCI in the second PDCCH is inverted, the transmitted system information is considered to be updated system information.
Optionally, in this embodiment of the present invention, after monitoring the second PDCCH, if it is determined that the target PDSCH includes updated system information, the updated system information may take effect in the next change period when the terminal device receives the updated system information.
Illustratively, if the change period of the network device configuration is 320ms, the terminal device receives Paging indication system information change at 100ms, and completes receiving updated system information at 120 ms. Then, the terminal device stores the updated system information, and before the next 320ms period (i.e., before the next change period), the current terminal behavior (e.g., measurement, random access, etc.) of the terminal device based on the system information is still performed based on the current non-updated system information, and when the next 320ms period is entered, the updated system information becomes effective, and the terminal behavior of the terminal device is performed based on the updated system information.
In the determining method provided by the embodiment of the present invention, the terminal device monitors the second PDCCH while monitoring the first PDCCH, so that the terminal device can determine whether the target PDSCH scheduled by the second PDCCH includes updated system information according to the monitored second PDCCH after learning that the system information is updated through the first PDCCH, so that the network device can transmit the updated system information on the currently acquired channel resource in time, and avoid a delay in transmitting the updated system information due to uncertainty of the channel resource.
