The embodiment of the present application provides a method for transmitting a paging message, which is applied to a mobile communication system of an unlicensed frequency band (especially for a cellular communication system operating independently in an unlicensed frequency band, such as MulteFire (referred to as MF)), a terminal and During the transmission of paging messages between base stations.

The mobile communication technology of the present application may be WCDMA (Wideband Code Division Multiple Access), CDMA2000 (Code Division Multiple Access 2000), and TD-SCDMA (Time Division-Synchronous Code Division). Multiple Access, Time Division Synchronous Code Division Multiple Access), WiMAX (Worldwide Interoperability for Microwave Access), LTE/LTE-A (Long Term Evolution/Long Term Evolution-Advanced) ), LAA (Licensed-Assisted Access, wireless access based on licensed bands), MulteFire, and subsequent fifth, sixth, and Nth generation mobile communication technologies.

For convenience of description, the following embodiments are described using an MF system of an unlicensed band. MulteFire is a wireless access technology that extends LTE to unlicensed bands, where unlicensed band carriers can be serviced independently without the aid of licensed band carriers. This technology has also become stand-alone LTE-U (stand-alone LTE-U). In order to interfere with other unlicensed band devices (such as WiFi devices) to occupy unlicensed band channels and avoid interference between unlicensed band devices, the MF physical layer introduces a WiFi-like carrier sensing technology (LBT, Listen Before) Talk) mechanism. When the base station or terminal monitors that the unlicensed band channel is occupied, that is, when the LBT fails, the signal is stopped, and when the channel is idle, that is, the LBT is successful, the signal is sent.

The base station refers to a form of a radio station, and refers to a radio access network device that transmits various messages to a terminal through a mobile communication switching center in a certain radio coverage area.

The terminal refers to a terminal side product that can support the communication protocol of the land mobile communication system, and a special modem module (Wireless Modem), which can be integrated by various types of terminal forms such as a mobile phone, a tablet computer, and a data card. Communication function.

The paging message is carried in the paging channel, and one of its main functions is to page a user to establish a connection with the network to implement data transmission and reception. The present application proposes a method for transmitting a paging message, that is, a paging channel and a control signaling transmission method for scheduling a paging channel, for paging transmission in a deep fading scenario, to improve transmission of an unlicensed band mobile communication system. effectiveness.

As shown in FIG. 1, the method includes:

101. The base station determines, according to a cell coverage enhancement capability, a time-frequency resource used for carrying a paging channel and a control signaling for scheduling a paging channel, where the time-frequency resource includes the paging channel and the scheduled paging channel. Control signaling repeats the number of subframes occupied by the transmission, and the paging channel and the control signaling of the scheduled paging channel repeatedly transmit one or more of the positional relationships in the time domain.

Wherein, when the time-frequency resource includes the number of subframes occupied by the paging channel repeated transmission, the paging channel repeated transmission occupies one or more subframes. That is, the paging channel is repeatedly transmitted in one or more subframes.

Wherein, when the time-frequency resource includes the number of subframes occupied by the control signaling repeated transmission of the scheduled paging channel, the control signaling repeated transmission of the scheduled paging channel occupies one subframe. That is, the control signaling of the scheduled paging channel is repeatedly transmitted in one subframe.

The paging channel and the control signaling of the scheduled paging channel repeatedly transmit the positional relationship in the time domain, and may have different configurations according to different communication requirements.

102. The base station sends control signaling of the paging channel and the scheduled paging channel to the terminal according to the determined time-frequency resource.

The terminal receives control signaling of the paging channel and the scheduled paging channel, and decodes the paging channel to obtain paging information.

It should be noted that, for the coverage enhanced user (the user who repeatedly transmits the paging message), the control signaling for scheduling the paging channel is based on an ePDCCH (enhance physical downlink control channel) or an mPDCCH (Machine-Type). The communication physical downlink control channel is transmitted.

The embodiment of the present application provides a method for transmitting a paging message. For a communication system operating in an unlicensed frequency band, the number of subframes occupied by the transmission of the paging channel and the scheduling paging channel is repeatedly transmitted, and they are The positional relationship in the time domain introduces more time-frequency resources to carry the paging channel and control signaling of the paging channel, and realizes repeated transmission of control signaling of the paging channel and the scheduled paging channel, thereby improving paging The transmission efficiency of the message realizes the coverage enhancement of the paging message.

Further, in combination with the foregoing method flow, when the time-frequency resource includes a positional relationship between the paging channel and the control signaling of the scheduled paging channel and the transmission in the time domain, the scheduling paging channel Control signaling and paging channels can be sent in different subframes in succession. Therefore, another possible implementation manner of the embodiment of the present application further provides the following method flow for the implementation of step 102, as shown in FIG. 2, including:

1021. The base station sends control signaling of the scheduled paging channel according to the determined time-frequency resource.

1022. After the control signaling of the scheduled paging channel is sent, the base station sends the paging channel in a next subframe.

In step 1021 and step 1022, the paging channel and the corresponding control signaling of the scheduled paging channel are not sent in the same subframe. Definition k is the initial transmission subframe of the paging channel in the time domain, and q is the end transmission subframe of the control signaling for scheduling the paging channel in the time domain, then k=q+1.

Further, in combination with the foregoing method flow, when the time-frequency resource includes a positional relationship between the paging channel and the control signaling of the scheduled paging channel, which is repeatedly transmitted in the time domain, the paging channel and scheduling The control signaling of the paging channel can also be transmitted simultaneously. Therefore, another possible implementation manner of the embodiment of the present application further provides the following method flow for the implementation of step 102, as shown in FIG. 3, including:

1023. The base station sends control signaling of the scheduled paging channel and the paging channel in the same subframe according to the determined time-frequency resource.

In step 1023, the paging channel and the corresponding control signaling of the scheduled paging channel are transmitted in the same subframe. According to the definition of k and q in step 1021 and step 1022, then k=q.

Further, in combination with the foregoing method flow, if the paging channel and the paging signal control signaling are repeatedly configured to transmit the positional relationship in the time domain by using a paging window (POW), a scheduling page can be defined. The control signaling of the channel is sent in the POW. Therefore, another possible implementation manner of the embodiment of the present application further provides the following method flow for the implementation of the step 102, including:

1024. The base station sends, according to the determined time-frequency resource, control signaling of the scheduled paging channel in a paging window.

The POW refers to the length of time that the control signaling of the scheduled paging channel can be sent.

In step 1024, the control signaling for scheduling the paging channel is sent within the POW, and may not be located outside the POW. The paging window is located in the paging frame (PF) and is only used to send control signaling for scheduling the paging channel. At this time, the paging channel can be sent outside the POW.

Further, in combination with the foregoing method flow, if the PW is used to configure the paging channel and the control signaling of the scheduled paging channel to repeatedly transmit the positional relationship in the time domain, the paging channel and its corresponding scheduled paging channel may also be defined. The control signaling is sent in the POW. Therefore, another possible implementation of the embodiment of the present application provides the following method flow for the implementation of the step 102, including:

1025. The base station sends control signaling of the scheduled paging channel and the paging channel in a paging window according to the determined time-frequency resource.

In step 1025, the paging channel and its corresponding scheduling paging channel control signaling are sent in the POW, and both channels are not located outside the POW. For a paging channel that cannot satisfy repeated transmission within one POW, the base station may choose not to transmit, or only transmit a part.

Here, the case where the base station transmits only a part of the paging channel is illustrated. As shown in FIG. 4, it is a schematic diagram of a base station transmitting a paging channel and scheduling paging channel control signaling in one POW, and transmitting only a part of the paging channel. In Figure 4, there are three paging channels and three control signaling corresponding to the scheduled paging channel, and 031 to 034 are subframes for channel transmission. Wherein, 011 represents a paging window length in which a paging message can be sent in a paging frame, and 021, 022, and 023 are control signalings for scheduling a paging channel, and are repeatedly transmitted in

subframes

031, 032, and 033, respectively. The scheduled paging channels are 041, 042, and 043, respectively. According to the cell coverage enhancement capability, all three paging channels need to be repeatedly transmitted in 3 subframes, such as paging channel 041. Since the paging channel must be within the POW, the

paging channels

042, 043 cannot satisfy the repeated transmission within one POW. Therefore, the base station transmits

paging channels

042, 043 in subframes 032/033 and subframe 033, respectively, and does not achieve maximum retransmission of

paging channels

042, 043. At this time, the base station may also choose not to transmit the

paging channel

042, 043, and also does not transmit the control signaling 022, 023 corresponding to the scheduled paging channel.

Further, in combination with the foregoing method, the control signaling for scheduling the paging channel is sent in any subframe in the PW or in the specified subframe. Therefore, another possible implementation manner of the embodiment of the present application is implemented for the step 102. The following two implementation methods are also provided.

The first way to achieve:

1026. The base station sends, according to the determined time-frequency resource, control signaling of the scheduled paging channel in any subframe in a paging window.

As shown in FIG. 5, a schematic diagram of control signaling and paging channels for transmitting a scheduled paging channel based on the first implementation method is shown. In FIG. 5, 231 to 236 are subframes for channel transmission, 211 represents a paging window length in which paging messages can be transmitted in one paging frame, and 221, 222, and 223 are control signaling for scheduling paging channels. Repeated transmissions are made in

subframes

231, 232, and 233, respectively, and the scheduled paging channels are 241, 242, and 243, respectively. In FIG. 5, the paging channel starts transmitting within one subframe after the control signaling corresponding to the scheduled paging channel. At the same time, due to coverage enhancement, any one paging channel is repeatedly transmitted in 3 subframes. The control signaling for scheduling the paging channel in FIG. 5 is not limited by other paging channels and can be transmitted in any subframe.

Therefore, based on the first implementation method, the coverage enhancement user needs to blindly check any subframe in a paging window, and obtain control signaling for scheduling the paging channel to obtain scheduling information. The process of decoding the paging message by the terminal that enhances the user is as follows:

Step 1: The DCI (Downlink Control Information) corresponding to the P-RNTI (Paging-Radio Network Temporary Identifier) is blindly detected in any one of the PWs.

The P-RNTI is used by the terminal to determine whether the currently blindly detected DCI is used to schedule a paging channel.

Step 2: Determine if the P-RNTI is detected. If yes, go to step 3; if no, go to step 4.

Step 3: The paging channel is received in m subframes after the control signaling for scheduling the paging channel is transmitted, and the paging message is decoded. At the same time, before the all subframes of the paging channel are not completely received, the DCI corresponding to the P-RNTI in any one of the m subframes is blindly solved based on the P-RNTI.

Where m is the number of subframes occupied by the paging channel in the time domain for repeated transmission. The value of m can be configured by upper layer signaling, or by scheduling control signaling of the paging channel, or by cell coverage enhancement capability and a predefined rule.

Step 4: Determine whether PagelessSfsToMonitor (a number of consecutive subframes that do not contain control signaling for scheduling paging channels) is reached. If yes, end paging detection; if no, return to step 1.

It should be noted that, when the result of the determination in step 4 is YES, the terminal can continue to detect the paging message, that is, return to step 1.

The PagelessSfsToMonitor is used by the terminal to determine whether to stop the blind control scheduling paging channel control signaling before the end of the POW, so as to save energy overhead.

Step 5: According to the decoding result in step 3, it is judged whether it is paged. If yes, stop paging message monitoring; if no, go to step 6.

Step 6: Determine if the POW is over. If it is over, stop paging message monitoring; if not, continue to blindly control the paging channel control signaling, that is, jump back to step 1.

The second way to achieve:

1027. The base station sends control signaling of the scheduled paging channel in a designated subframe in a paging window according to the determined time-frequency resource.

Based on the second implementation method, the specific implementation may have the following two examples: First, the control signaling for scheduling the paging channel may occur once every n subframes, n depends on the repeated transmission of the paging channel in the time domain. The number of occupied subframes m, that is, the value of n depends on the upper layer signaling configuration, the control signaling for scheduling the paging channel, or the coverage enhancement capability of the cell. Let the interval between the paging channel start transmitting subframe and the control paging end scheduling subframe of the scheduled paging channel be p, then n=m+p. Secondly, a specific subframe within the paging window can be specified, for example, subframe 0 and subframe 5 are used to send control signaling for scheduling paging, without regard to the number of subframes occupied by repeated transmission of the paging channel.

As shown in FIG. 6, a schematic diagram of control signaling and paging channels for transmitting a scheduled paging channel based on the first example of the second implementation method is shown. In FIG. 6, 431 to 436 are subframes for channel transmission, 411 represents a paging window length in which paging messages can be transmitted in one paging frame, and 421 and 422 are control signaling for scheduling paging messages, respectively. The

sub-frames

431 and 434 are repeatedly transmitted, and the scheduled paging messages are 441 and 442, respectively. In FIG. 6, the control signaling of the paging channel and the corresponding scheduled paging channel starts to be transmitted in the same subframe. At the same time, due to coverage enhancement, any one paging channel is repeatedly transmitted in 3 subframes. The control signaling for scheduling the paging channel in FIG. 6 is not transmitted in any subframe, but is transmitted in the subframe after the transmission of the previous paging channel ends, and is transmitted every three subframes, that is, n is 3, m. Is 3, p is 0.

Therefore, based on the second implementation method, the control signaling for scheduling the paging channel appears in a specific subframe within a paging window, and the user does not specify a subframe after the repeated transmission of the paging channel. The DCI corresponding to the P-RNTI is blindly detected during the transmission of the paging channel. The process of covering the enhanced user only blindly detects the control signaling of the paging message on a specific subframe, and the process of decoding the paging message is as follows:

Step 1: According to the cell coverage enhancement capability, determine the number of subframes occupied by the paging channel in the time domain, and determine the subframe in which the control signaling of the paging channel can be transmitted in one POW, and in the corresponding subframe. The DCI corresponding to the P-RNTI is blindly detected.

Step 3: The paging channel is received in m subframes and the paging message is decoded.

Step 4: Determine if PagelessSfsToMonitor is reached. If yes, end paging detection; if no, return to step 1. Note that when the judgment result is YES, the enhanced user can still continue to detect the paging message, that is, return to step 1.

Step 5: According to the decoding result of step 3, it is judged whether it is paged. If yes, stop paging message monitoring; if no, go to step 6.

Further, in combination with the foregoing method flow, when considering the positional relationship between the transmission window of the Discovery Reference Signal (DRS) and the paging window in the time domain, the paging window and the DRS transmission window may overlap. That is, the paging message and the DRS coexistence transmission, and the sending of the DRS can also send the paging message; or no overlap occurs.

In the conventional MF system, the transmission of the paging message may occur in one subframe simultaneously with the DRS, or the transmission subframe of the paging message overlaps with the transmission window of the DRS. In the embodiment of the present application, the paging window may overlap with the DRS transmission window in time, or may not overlap. The implementation of whether the overlap is specific can be configured through upper layer signaling. The DRS includes a DRS signal sent to a normal user and an enhanced DRS sent to the coverage enhanced user.

Further, in combination with the foregoing method flow, when the paging window overlaps with the DRS transmission window, due to the diversity of control signaling and/or paging channel scrambling modes of the paging channel, another embodiment of the present application A possible implementation also provides the following two scrambling rules, which are performed before step 102.

The first scrambling rule, as shown in Figure 7, includes:

103. For control signaling and/or paging channel of a scheduled paging channel located in a sounding reference signal transmission window, the base station according to control signaling of the scheduled paging channel and/or an index of a subframe in which the paging channel is currently located Perform scrambling.

For the coverage enhancement user, when the paging window and the DRS transmission window overlap in time, the control signaling for scheduling the paging channel located in the DRS transmission window is scrambled according to the index of the currently located subframe, that is, The scrambling sequence is obtained from the current sub-frame index. Similarly, the corresponding scheduled paging channel is also scrambled according to the index of the currently located subframe. Therefore, when the paging channel performs repeated transmission in multiple subframes, the coverage enhancement user needs to decode and descramble the paging channel of each subframe through the index of the corresponding subframe, and then combine to obtain paging information.

According to the first type of scrambling rule, the control signaling for scheduling the paging channel is repeatedly transmitted in one subframe, and the scrambling sequence is obtained by formula (1).

Where c _init represents the initial seed of the generated wrap sequence, and n _s represents the current sub-frame index.

Representing the cell ID, the scrambling sequence of the control signaling for scheduling the paging channel is common to the cell.

For the paging channel, the scrambling sequence can be obtained in the same way, and will not be described again.

The second scrambling rule, as shown in Figure 8, includes:

104. For control signaling and/or paging channel of the scheduled paging channel located in the sounding reference signal transmission window, the base station performs scrambling according to the location where the sounding reference signal starts transmitting the subframe.

For the coverage enhanced user, when the paging window and the DRS transmission window overlap in time, the control signaling of the scheduled paging channel located in the DRS transmission window, the scrambling sequence is based on the location where the DRS starts transmitting the subframe. owned. That is, when the initial transmission subframe of the DRS is the first half frame, and the control signaling for scheduling the paging channel is also located in the first half frame, that is, subframe 0-subframe 4, the scrambling sequence is generated according to the subframe 0; when the DRS is The initial transmission subframe is the second half frame, and the control signaling for scheduling the paging channel is also located in the second half frame, that is, subframe 5-subframe 9, and the scrambling sequence is generated according to the subframe 5. Similarly, the corresponding scheduled paging channel is scrambled in the same manner. Therefore, when the paging channel is repeatedly transmitted in a plurality of subframes, the coverage enhancement user can directly combine the paging channels in the plurality of subframes and then perform decoding. Because at this time, the same paging channel in multiple subframes uses the same scrambling sequence.

It should be noted that when the paging channel is not in the DRS transmission window, scrambling may not be performed according to the second scrambling rule.

According to the second scrambling rule, the control signaling for scheduling the paging channel is repeatedly transmitted in one subframe, and the scrambling sequence thereof is obtained by formula (2).

In order to overlap the paging window and the DRS transmission window, the second scrambling rule is explained more clearly. The second scrambling rule is further explained by the schematic diagram of the paging message and the DRS coexistence transmission in FIG. In Fig. 9, 631 to 637 are subframes for channel transmission, 601 indicates a DRS transmission window, 602 indicates a paging window, and 601 and 602 have temporal overlap. 611 denotes transmission of DRS. To achieve coverage enhancement, DRS occupies subframe 631 and subframe 632. 621 is control signaling for scheduling paging channel 641, initial transmission subframe of 641 is inside 601, and scrambling sequence of 641 is based on 631 is generated by the position of the sub-frame. When 631 is subframe 0-subframe 4, the scrambling sequence of 641 is obtained according to subframe 0; when the 631 subframe is subframe 5-subframe 9, the scrambling sequence of 641 is obtained according to subframe 5. The paging channel 642 of Figure 9 is scheduled by scheduling control signaling 622 of the paging channel, 642 being located outside of 601, so the scrambling of 642 is not affected by 611.

Further, in combination with the foregoing method flow, when the paging window does not overlap with the DRS transmission window, due to the diversity of the control signaling and/or the paging channel scrambling mode of the paging channel, the other embodiment of the present application One possible implementation also provides the following two scrambling rules, which are performed before step 102.

The first type of scrambling rule, as shown in Figure 10, includes:

105. For control signaling and/or paging channel for scheduling a paging channel, the base station performs scrambling according to control signaling of the scheduled paging channel and/or an index of a subframe in which the paging channel is currently located.

The second scrambling rule, as shown in Figure 11, includes:

106. For control signaling and/or paging channel for scheduling a paging channel, the base station performs scrambling according to control signaling of the scheduled paging channel and/or a location where the paging channel starts transmitting the subframe.

For the coverage enhanced user, when the paging window and the DRS transmission window do not overlap in time, in the first type of scrambling rule, the generation of the paging message scrambling sequence depends on the index of the subframe in which the paging message is repeatedly transmitted; In the two scrambling rules, the generation of the paging message scrambling sequence depends on the location where the paging message starts to transmit the subframe, and the same scrambling sequence is used in the repeated transmission.
