Description

Transmission method and device of paging message

[ background of the invention ]

The communication system provides communication services to the user terminal through radio access network equipment (e.g., a base station) and core network equipment (e.g., a home location register), etc. At present, because the geographical location of some user terminals is special (such as water meter/electricity meter of basement), when the user terminal at the geographical location communicates with the base station, the signal penetration loss is large, the channel fading is large, and finally the communication quality of the user terminal is reduced. Therefore, there is a need to increase the signal energy or quality between the ue and the base station, and to perform coverage enhancement on each signal between the ue and the base station, including paging messages. The paging message is loaded in a paging channel, and the coverage enhancement is carried out on the paging message, including the coverage enhancement on the paging channel and the control signaling of a scheduling paging channel.

In the prior art, for a communication system operating in an authorized frequency band, control signaling of a paging channel and a scheduling paging channel are transmitted based on a narrow band.

The embodiment of the invention provides a transmission method of a paging message, which is applied to a mobile communication system in an unauthorized frequency band (especially to a cellular communication system independently working in the unauthorized frequency band, such as MulteFire (MF for short)), and the transmission process of the paging message between a terminal and a base station.

The mobile communication technology of the present invention may be WCDMA (Wideband Code Division Multiple Access), CDMA2000(Code Division Multiple Access 2000), TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, Time Division Synchronous Code Division Multiple Access), WiMAX (world Interoperability for Microwave Access), LTE/LTE-a (Long Term Evolution/Long Term Evolution-Advanced, Long Term Evolution/enhanced, Long Term Access, radio Access based on authorized frequency band), multimedia, and fifth, sixth, and nth generation mobile communication technologies that may appear subsequently.

For convenience of description, the following embodiments are illustrated with an MF system in an unlicensed frequency band. MulteFire is a radio access technology that extends LTE to unlicensed bands, in which unlicensed band carriers can independently provide services without the help of licensed band carriers. This technology also becomes stand-alone LTE-U (stand-alone LTE-U). In order to fairly occupy the unlicensed band channel and avoid mutual interference between unlicensed band devices and other devices in the unlicensed band (e.g., WiFi devices), the MF physical layer introduces a Listen-Before-Talk (LBT) mechanism similar to the WiFi carrier sensing technique. When the base station or the terminal monitors that the unlicensed frequency band channel is occupied, namely LBT fails, the signal is stopped being sent, and when the channel is monitored to be idle, namely LBT succeeds, the signal is sent.

The base station refers to a form of radio station, and refers to a radio access network device that sends 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 capable of supporting a communication protocol of a land mobile communication system, and a special communication Modem module (Wireless Modem) can be integrated by various terminal forms such as a mobile phone, a tablet computer, a data card and the like to complete a communication function.

The paging message is carried in the paging channel, and one main function of the paging channel is to page a certain user to establish connection with the network so as to realize data transceiving. The invention provides a transmission method of a paging message, namely a transmission method of a paging channel and a control signaling of a scheduling paging channel, which is used for paging transmission in a deep fading scene so as to improve the transmission efficiency of an unauthorized frequency band mobile communication system.

As shown in fig. 1, the method includes:

101. the base station determines time-frequency resources for bearing control signaling of a paging channel and a scheduling paging channel according to the cell coverage enhancement capability, wherein the time-frequency resources comprise one or more of the number of subframes occupied by the repeated transmission of the control signaling of the paging channel and the scheduling paging channel and the position relation of the repeated transmission of the control signaling of the paging channel and the scheduling paging channel in the time domain.

When the time-frequency resource comprises the number of subframes occupied by the paging channel repeated transmission, the paging channel repeated transmission occupies one or more subframes. I.e. the paging channel is repeatedly transmitted in one or more subframes.

Wherein, when the time frequency resource comprises the number of subframes occupied by the control signaling repeated transmission of the scheduling paging channel, the control signaling repeated transmission of the scheduling paging channel occupies one subframe. I.e. the control signaling of the scheduled paging channel is repeatedly transmitted within one subframe.

The position relation of the paging channel and the control signaling repeated transmission of the scheduling paging channel on the time domain can have different configurations according to different communication requirements.

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

And the terminal receives the paging channel and the control signaling of the scheduling paging channel, and decodes the paging channel to acquire paging information.

It should be noted that, for coverage enhancement users (users who repeatedly transmit paging messages), the control signaling for scheduling the paging channel is transmitted based on an ePDCCH (enhanced physical downlink control channel) or an mPDCCH (Machine-Type Communication physical downlink control channel).

The embodiment of the invention provides a transmission method of paging messages, aiming at a communication system working in an unauthorized frequency band, more time-frequency resources are introduced to bear the control signaling of a paging channel and a scheduling paging channel by configuring the number of subframes occupied by the repeated transmission of the control signaling of the paging channel and the scheduling paging channel and the position relation of the subframes on a time domain, so that the repeated transmission of the control signaling of the paging channel and the scheduling paging channel is realized, the transmission efficiency of the paging messages is improved, and the coverage enhancement of the paging messages is realized.

Further, in combination with the foregoing method flow, when the time-frequency resource includes a position relationship between the paging channel and the control signaling of the scheduling paging channel repeatedly transmitted in the time domain, the control signaling of the scheduling paging channel and the paging channel may be transmitted in sequence in different subframes. Therefore, another possible implementation manner of the embodiment of the present invention provides the following method flow for implementing step 102, as shown in fig. 2, including:

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

1022. And after the control signaling of the scheduling paging channel is sent, the base station sends the paging channel in the next subframe.

In steps 1021 and 1022, the control signaling of the paging channel and the corresponding scheduling paging channel are not transmitted in the same subframe. Defining k as a starting transmission subframe of a paging channel in a time domain, and q as an ending transmission subframe of control signaling of a scheduling paging channel in the time domain, and then k is q + 1.

Further, in combination with the foregoing method procedure, when the time-frequency resource includes a position relationship between the paging channel and the control signaling of the scheduling paging channel repeatedly transmitted in the time domain, the control signaling of the paging channel and the control signaling of the scheduling paging channel may also be transmitted simultaneously. Therefore, another possible implementation manner of the embodiment of the present invention provides the following method flow for implementing step 102, as shown in fig. 3, including:

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

In step 1023, the control signaling for the paging channel and the corresponding scheduling paging channel are sent in the same subframe. Defined as k and q in step 1021 and step 1022, k equals q.

Further, in combination with the foregoing method flow, if a paging window (POW) is used to configure a location relationship between a paging channel and a control signaling repeatedly transmitted on a scheduling paging channel in a time domain, it may be defined that the control signaling of the scheduling paging channel is sent in the POW, so another possible implementation manner of the embodiment of the present invention further provides the following method flow for implementing step 102, including:

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

Here, POW refers to a length of time in which control signaling for scheduling a paging channel can be transmitted.

In step 1024, the control signaling for scheduling paging channel is sent in POW, but not outside POW. The paging window is located in a Paging Frame (PF) and is only used for transmitting control signaling for scheduling a paging channel, and the paging channel may be transmitted outside the POW.

Further, in combination with the foregoing method flow, if POW is used to configure the location relationship of the paging channel and the control signaling of the scheduling paging channel repeatedly transmitted in the time domain, it may also be defined that both the paging channel and the control signaling of the scheduling paging channel corresponding to the paging channel are transmitted in the POW, so another possible implementation manner of the embodiment of the present invention further provides the following method flow for implementing step 102, including:

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

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

Here, a case where the base station transmits only a part of the paging channels will be described. As shown in fig. 4, the base station is shown to transmit the paging channel and the control signaling for scheduling the paging channel in one POW, and only transmits a part of the paging channel. In fig. 4, there are three paging channels and three control signaling corresponding to the scheduled paging channels, and 031 through 034 are subframes for channel transmission. Where 011 represents the paging window length for sending paging messages in a paging frame, 021, 022, and 023 are control signaling for scheduling paging channels, which are repeatedly transmitted in

subframes

031, 032, and 033, respectively, and the scheduled paging channels are 041, 042, and 043, respectively. According to the cell coverage enhancement capability, three paging channels are required to be repeatedly transmitted in 3 subframes, such as the 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 and 043 in sub-frames 032/033 and 033, respectively, and does not achieve maximum repetition transmission of the

paging channels

042 and 043. In this case, the base station may choose not to transmit the

paging channels

042 and 043, and may also not transmit the control signaling 022 and 023 corresponding to the scheduling paging channels.

Further, in combination with the foregoing method flow, the control signaling for scheduling the paging channel is sent in any subframe or in a designated subframe in the POW, so that another possible implementation manner of the embodiment of the present invention provides the following two implementation methods for implementing step 102.

The first realization method comprises the following steps:

1026. and the base station sends the control signaling of the scheduling paging channel at any subframe in a paging window according to the determined time-frequency resource.

As shown in fig. 5, a schematic diagram of the control signaling and paging channel for transmitting the scheduling paging channel according to the first implementation method is shown. In fig. 5, 231 to 236 are subframes of channel transmission, 211 represents a paging window length in a paging frame in which a paging message can be transmitted, 221, 222, 223 are control signaling for scheduling a paging channel, and the paging channel is repeatedly transmitted in the

subframes

231, 232, 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. Meanwhile, due to coverage enhancement, any one paging channel is repeatedly transmitted within 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 detect any subframe in a paging window to obtain the control signaling of the scheduling paging channel to obtain the scheduling information. The process of decoding the paging message by the terminal of the coverage enhancement user is as follows:

step 1: and blind detecting DCI (Downlink Control Information) corresponding to P-RNTI (Paging-Radio Network Temporary Identifier) in any subframe in the POW.

The P-RNTI is used for the terminal to judge whether the DCI which is detected in the current blind mode is used for scheduling a paging channel.

Step 2: and judging whether the P-RNTI is detected. If yes, entering step 3; if not, go to step 4.

And step 3: and receiving the paging channel in m subframes after the control signaling of the scheduling paging channel is sent, and decoding the paging message. And meanwhile, before all subframes of the paging channel are not completely received, the DCI corresponding to the P-RNTI in any one subframe of the m subframes is blindly decoded based on the P-RNTI.

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

And 4, step 4: it is determined whether or not pagelesssftosmonitor (the number of consecutive subframes not containing the control signaling for scheduling paging channel) is reached. If yes, ending the paging detection; if not, returning to the step 1.

It should be noted that, when the determination result in step 4 is yes, the terminal may still continue to detect the paging message, that is, return to step 1.

The pagelesssftostonmonitor is used for the terminal to judge whether to stop the control signaling of the blind test scheduling paging channel before the POW is finished so as to save energy overhead.

And 5: and judging whether the paging is carried out or not according to the decoding result in the step 3. If yes, stopping monitoring the paging message; if not, go to step 6.

Step 6: it is determined whether the POW is finished. If the paging message is finished, stopping monitoring the paging message; if not, continuing to blindly detect the control signaling of the scheduling paging channel, namely jumping back to step 1.

The second realization method comprises the following steps:

1027. and the base station appoints a subframe to send the control signaling of the scheduling paging channel in a paging window according to the determined time-frequency resource.

Based on the second implementation method, there may be two specific implementations as follows: first, the control signaling for scheduling the paging channel may appear once every n subframes, where n depends on the number m of subframes occupied by the repeated transmission of the paging channel in the time domain, that is, the value of n depends on the configuration of the upper layer signaling, the control signaling for scheduling the paging channel, or the coverage enhancement capability of the cell. And if the interval between the paging channel starting transmission subframe and the control signaling ending transmission subframe of the scheduling paging channel is p, n is m + p. Second, specific subframes within the paging window, e.g., subframe 0, subframe 5, may be designated for transmitting control signaling for scheduling paging regardless of the number of subframes occupied by repeated transmissions of the paging channel.

As shown in fig. 6, a schematic diagram of a paging channel and control signaling for scheduling the paging channel according to a first example of the second implementation method is shown. In fig. 6, reference numerals 431 to 436 denote subframes for channel transmission, 411 denotes a paging window length within one paging frame in which a paging message can be transmitted, 421 and 422 denote control signaling for scheduling the paging message, which is repeatedly transmitted in

subframes

431 and 434, respectively, and whose scheduled paging messages are 441 and 442, respectively. In fig. 6, the control signaling for the paging channel and the corresponding scheduling paging channel are transmitted starting in the same subframe. Meanwhile, due to coverage enhancement, any one paging channel is repeatedly transmitted within 3 subframes. In fig. 6, the control signaling for scheduling the paging channel is not transmitted in any subframe, but is transmitted in the subframe after the transmission of the previous paging channel is finished, and is transmitted every 3 subframes, i.e., n is 3, m is 3, and p is 0.

Therefore, based on the second implementation method, the control signaling for scheduling the paging channel appears in a specific subframe in a paging window, and after the user specifies the number of subframes occupied by the repeated transmission of a paging channel, the DCI corresponding to the P-RNTI is not blindly detected during the transmission period of the paging channel. The terminal of the coverage enhancement 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, the number of subframes occupied by the repeated transmission of the paging channel in the time domain is judged, the subframe which can send the control signaling of the scheduling paging channel in one POW is determined, and the DCI corresponding to the P-RNTI is detected in the corresponding subframe in a blind mode.

And step 3: the paging channel is charged in m subframes and the paging message is decoded.

And 4, step 4: it is determined whether the PagelessSfsToMonitor is reached. If yes, ending the paging detection; if not, returning to the step 1. Note that, when the determination result is yes, the enhanced user may still continue to detect the paging message, i.e., return to step 1.

And 5: and judging whether the paging is carried out or not according to the decoding result of the step 3. If yes, stopping monitoring the paging message; if not, go to step 6.

Further, in combination with the foregoing method flow, when considering a position relationship between a sounding Reference Signal (DRS) transmission window and a paging window in a time domain, the paging window and a DRS transmission window may overlap, that is, a paging message and a DRS coexist for transmission, and a paging message may also be sent while the DRS is sent; or no overlap may occur.

In a 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 and the transmission window of the DRS overlap. In the embodiment of the present invention, the paging window may overlap with the DRS transmission window in time, or may not overlap. The implementation of whether overlapping is specific can be configured through upper layer signaling. Wherein, the DRS comprises DRS signals sent to normal users and enhanced DRS sent to coverage enhanced users.

Further, in combination with the foregoing method flow, when the paging window overlaps with the DRS transmission window, due to the diversity of the control signaling for scheduling the paging channel and/or the scrambling manner of the paging channel, another possible implementation manner of the embodiment of the present invention further provides the following two scrambling rules, which are executed before step 102.

The first scrambling rule, as shown in fig. 7, includes:

103. and for the control signaling and/or the paging channel of the scheduling paging channel in the sounding reference signal sending window, the base station scrambles according to the control signaling and/or the index of the current subframe of the scheduling paging channel.

For coverage enhancement users, when a paging window and a DRS transmission window are overlapped in time, a control signaling for scheduling a paging channel in the DRS transmission window is scrambled according to the index of the current subframe, namely the scrambling sequence is obtained by the index of the current subframe. Similarly, the paging channel to be scheduled is scrambled according to the index of the subframe where the paging channel is currently located. Therefore, when the paging channel is repeatedly transmitted in a plurality of 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 merge to acquire paging information.

According to the first scrambling rule, the control signaling of the paging channel is scheduled to be transmitted repeatedly in a subframe, and the scrambling sequence is obtained by formula (1)

Wherein, c_initInitial seed, n, representing the generation of a wrapped sequence_sIndicating the index of the current sub-frame,

representing the cell ID, the scrambling sequence of the control signaling scheduling the paging channel is cell-common.

The scrambling sequence can be obtained by the same principle for the paging channel, and is not described in detail.

The second scrambling rule, as shown in fig. 8, includes:

104. and for the control signaling and/or the paging channel of the scheduling paging channel in the sounding reference signal sending window, the base station scrambles according to the position of the initial sending subframe of the sounding reference signal.

For coverage enhancement users, when a paging window and a DRS transmission window are overlapped in time, a scrambling sequence of a control signaling of a scheduling paging channel in the DRS transmission window is obtained according to the position of a DRS initial transmission subframe. That is, when the initial transmission subframe of DRS is the first half frame and the control signaling for scheduling the paging channel is also located in the first half frame, i.e., subframe 0-subframe 4, its scrambling sequence is generated according to subframe 0; when the initial transmission subframe of the DRS is a second half frame and the control signaling for scheduling the paging channel is also located in the second half frame, i.e., subframe 5 to subframe 9, the scrambling sequence is generated according to 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 decode the combined paging channels. Because at this time the same paging channel within multiple subframes uses the same scrambling sequence.

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

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

which indicates the cell ID of the cell,

In order to explain the second scrambling rule more clearly when the paging window overlaps with the DRS transmission window, the second scrambling rule is further explained with reference to fig. 9, which is a schematic diagram of coexistence transmission of paging messages and DRSs. In fig. 9, 631 to 637 are subframes of channel transmission, 601 denotes a DRS transmission window, 602 denotes a paging window, and 601 and 602 have temporal overlap. 611 denotes the transmission of DRS, which occupies subframe 631 and subframe 632 in order to achieve coverage enhancement. 621 is control signaling to schedule paging channel 641, the starting transmission subframe of 641 is inside 601, and the scrambling sequence of 641 is generated according to the position of 631 subframes. When 631 is subframe 0-subframe 4, the scrambling sequence of 641 is derived from subframe 0; when 631 subframes are subframe 5-subframe 9, the scrambling sequence of 641 results from subframe 5. In fig. 9, paging channel 642 is scheduled by control signaling 622 scheduling the paging channel, and 642 is located outside 601, so scrambling of 642 is not affected by 611.

Further, in combination with the foregoing method flow, when the paging window and the DRS transmission window are not overlapped, due to the diversity of the control signaling for scheduling the paging channel and/or the scrambling manner of the paging channel, another possible implementation manner of the embodiment of the present invention further provides the following two scrambling rules, which are executed before step 102.

The first scrambling rule, as shown in fig. 10, includes:

105. and for the control signaling and/or the paging channel of the scheduling paging channel, the base station scrambles according to the control signaling and/or the index of the current subframe of the scheduling paging channel.

The second scrambling rule, as shown in fig. 11, includes:

106. and for the control signaling and/or the paging channel of the scheduling paging channel, the base station scrambles according to the position of the initial sending subframe of the control signaling and/or the paging channel of the scheduling paging channel.

For coverage enhancement users, when a paging window and a DRS transmission window are not overlapped in time, in a first scrambling rule, generation of a paging message scrambling sequence depends on an index of a subframe in which a paging message is repeatedly transmitted; in the second scrambling rule, the generation of the paging message scrambling sequence depends on the position of the paging message initial transmission subframe, and the same scrambling sequence is adopted in the repeated transmission process.
