detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments.

Embodiment 1

The system architecture provided by the embodiment of the present invention is an M2M system. In the M2M system, if the UE does not receive the SI correctly, the UE will not be able to perform normal communication, which will affect the user experience and reduce the stability of the M2M system. Therefore, the reliability and correctness of SI is critical to the performance quality of M2M systems.

In the M2M system provided by the embodiment of the present invention, in order to ensure the transmission reliability of the UE located in a place with poor network coverage, the time domain spread spectrum may be used to enhance the network coverage of the M2M system. As shown in Figure 1, it is assumed that the A area is the area with good network coverage, the B area is the area with poor network coverage, and the C area is the area with poor network coverage. If the A area does not need to be spread, It can guarantee the transmission reliability of UE1 (A area can be called 1X area); B area needs 8 times of spreading to ensure the transmission reliability of UE2 (B area can be called 8X area); C area needs 64 times of spread spectrum In order to ensure the transmission reliability of UE3 (C area can be called 64X area).

In the M2M system provided by the embodiment of the present invention, as shown in FIG. 2, taking an 8X area as an example, one original data frame is 80 milliseconds, and a new data frame formed after 8 times of spreading is 80*8= At 640 milliseconds, the new data frame is repeated for 8 times to form a superframe, which is 640*8=5120 milliseconds (5.12 seconds). The length of time of one new data frame is 8 times of the length of one original data frame; the length of time of one super frame is 8 times of the length of one new data frame, which is one original data. 64 times the length of the frame.

Further, in order to more clearly and completely describe the transmission method of the SI provided by the embodiment of the present invention, the following embodiments are exemplified by taking the 8X area in the M2M system as an example. Certainly, the embodiments of the present invention include but are not limited to the 8X area in the M2M system, and the transmission methods of the SIs in other areas, such as the 16X area, the 32X area, and the 64X area, are similar to the transmission methods of the SI in the 8X area. The data frame mentioned in the following embodiments refers to a new data frame formed by the above-mentioned original data frame after 8 times of spreading, in order to describe the transmission method of the SI provided by the embodiment of the present invention. The new data frame may also be referred to as a spread spectrum frame.

In the method for transmitting the SI provided by the embodiment of the present invention, before the base station broadcasts the SI, the base station needs to first map the S1 from the logical channel to the physical channel, and then send the signal on the physical channel. The logical channel may be a broadcast control channel (abbreviation: BCCH); the transport channel may be a broadcast channel (abbreviation: BCH); the physical channel may be a physical broadcast channel (English: physical broadcast) Channel, abbreviation: PBCH), or PBCH and physical downlink share channel (English: physical downlink share channel, abbreviation: PDSCH).

The executor of the method for transmitting the SI according to the embodiment of the present invention may be a base station or a UE, and the base station may be an evolved base station (English: evolved node base station, eNB). A method for transmitting an SI according to an embodiment of the present invention is described in detail below by using a base station and a UE as an example.

An embodiment of the present invention provides a method for transmitting an SI. As shown in FIG. 3, the method may include:

S101. The base station maps the first SI to the first PBCH.

S102. The base station continuously sends the first SI times m times on the first PBCH, where m is an integer greater than 1.

In the embodiment of the present invention, as shown in FIG. 4, when the base station sends the first SI to the UE, the first SI needs to first map the first SI from the BCCH to the first PBCH through the BCH. The BCCH is a logical channel, the BCH is a transport channel, and the first PBCH is a physical channel.

It should be noted that the transmission method of the SI provided by the embodiment of the present invention can be applied to the M2M system. In each coverage area of the M2M system, in order to enable the UE to correctly receive the SI, that is, to enhance the reliability of the SI transmission, the base station transmits the SI. It needs to be sent repeatedly. For example, in the 8X area, the base station can continuously transmit 8 times of SI; in the 16X area, the base station can continuously transmit 16 times of SI; and so on, in the mX area, the base station can continuously transmit m times of SI, and m can be greater than 1. Integer. Specifically, the method for transmitting the SI in the mX region is the same as the method for the base station to send the SI in the 8X region in the following embodiment. Therefore, in this embodiment, only the method in which the base station sends the SI in the 8X region is taken as an example. For the description, other coverage areas will not be described one by one.

Optionally, the first S1 may be k SIBs in n system information blocks (SIB), where n is a positive integer, k is a positive integer, k≤n . Exemplarily, the first SI may be SIB1, SIB2, ..., SIBk, and SIB1 may specifically be a master information block (English: master information block, abbreviated as MIB).

As shown in FIG. 5, when the first SI is the k SIBs of the n SIBs, the S102, that is, the base station continuously sends the first SI times on the first PBCH, which may be:

S102a. The base station sends k SIBs on m×k consecutive data frames on the first PBCH.

Specifically, in S102a, the method for the base station to send k SIBs on the m×k consecutive data frames on the first PBCH may be one of the following:

(a) the base station continuously transmits the first of the k SIBs on the m×(i-1)+1th data frame to the m×ith data frame in the m×k consecutive data frames on the first PBCH i SIBs, where i is a positive integer, i ≤ k.

As shown in FIG. 6, it is assumed that the 8X area is taken as an example, m=8, one superframe includes 8 data frames, and the 8 data frames are sequentially numbered as data frame No. 1, data frame No. 2, ... , No. 8 data frame. The base station continuously transmits the i-th SIB of the k SIBs on the 8×(i-1)+1th data frame to the 8×th data frame of the 8×k consecutive data frames on the first PBCH. (ie SIBi).

Specifically, after continuously transmitting the SIBs one time, the base station continuously transmits the next SIBs m times, and so on, when the base station sequentially sends the k SIBs in succession, that is, the base station sequentially sends each SIB separately and continuously for m times. The base station can start the process of transmitting the next k SIBs according to the method of (a) above. That is, the base station can periodically transmit k SIBs according to the method of (a) above.

The method of the foregoing (a) may facilitate the extension of the first SI, that is, when the first SI needs to be extended, the information extended in the first SI may be continuously transmitted repeatedly on the first PBCH without affecting the first SI central Some information is transmitted.

(b) the base station transmits the i-th SIB of the k SIBs on the i+k×(j-1) data frames in the m×k consecutive data frames on the first PBCH; wherein i is positive Integer, j is a positive integer, i ≤ k, j ≤ m.

As shown in FIG. 7, it is assumed that the 8X system is taken as an example, m=8, one superframe includes 8 data frames, and 8 data frames are sequentially numbered as data frame No. 1, data frame No. 2, ... , No. 8 data frame. The base station transmits the i-th SIB (ie, SIBi) of the k SIBs on the i+k×(j-1) data frames of the 8×k consecutive data frames on the first PBCH.

Specifically, after the base station transmits one SIB once, and then continuously transmits the next SIB, and so on, after the base station continuously transmits one k SIBs, the base station continuously transmits the next k SIBs, and the base station repeats m. After sending k SIBs in succession, that is, after the base station continuously transmits k SIBs together for m times, the base station may start the process of transmitting the next k SIBs according to the method of (b) above. That is, the base station periodically transmits k SIBs according to the method of (b) above.

In the method of (b) above, if the UE receives the first SI sent by the base station at least once, the UE may not continue to monitor the first PBCH to receive the first SI, so that the UE can save the UE. Power consumption.

It should be noted that the k SIBs included in the first SI may be understood as: the k SIBs include configuration parameters necessary for the UE camping cell and the access cell. The information block included in the specific first SI may be determined according to actual conditions, and the present invention is not limited.

In particular, the value of k can usually be 1, 2 or 3. Wherein, when the value of k is 1, 2, or 3, it indicates that SIB1 (may also be MIB), SIB1-SIB2, or SIB1-SIB3 are required to transmit important parameters necessary for UE communication (can be resident and connected) Into the necessary parameters), so that the UE can fully acquire these parameters when there are more important parameters necessary for UE communication.

Optionally, when n>k, it is assumed that k SIBs in the n SIBs are understood as the first SI, and nk SIBs different from the k SIBs in the n SIBs are understood as the second SI; The time between consecutively transmitting m times of the second SI to the next consecutive transmission of the second SI by the base station is recorded as the period in which the base station continuously transmits m times of the second SI, and the base station transmits the first SI one time to the next consecutive sequence of the base station. The time between sending the first SI times is recorded as the period in which the base station continuously transmits m times of the first SI, and the period in which the base station continuously transmits the second SI times may be the same as the period in which the base station continuously transmits the first time of the m times; or The period in which the second SI is continuously transmitted m times may be an integer multiple of the period in which the base station continuously transmits m times of the first SI, which is not limited in the present invention.

For example, the period in which the base station continuously transmits m times of the first SI may be a k* time-frequency repetition period, where k is the number of SIBs; the period in which the base station continuously transmits m times of the second SI may also be a k* time-frequency repetition period. Alternatively, the period in which the base station continuously transmits the second SI times may also be an integer multiple of the k* time-frequency repetition period. The time-frequency repetition period may be the length of one superframe. For example, in the 8X region, the time-frequency repetition period is 80 milliseconds*8*8=5.12 seconds.

Optionally, the period T1 in which the base station continuously transmits m times of the first SI may be the above-mentioned k* time-frequency repetition period; the period T2 in which the base station continuously transmits m times of the second SI may be a k* time-frequency repetition period (same as T1) It can also be an integer multiple of the k* time-frequency repetition period (T2 is an integer multiple of T1). Specifically, if T1 and T2 are the same, the base station continuously transmits the first SI/second SI m times in each T1/T2; if T2 is an integer multiple of T1, the base station continuously transmits m in each T1. The first SI, and an integer multiple of each T1, that is, T2 The second SI is transmitted m times in succession.

For example, as shown in FIG. 8, assuming that the first SI is SIB1 and the second SI is SIB2-SIB4, the base station continuously transmits 8 SIB1 and SIB2-SIB4 in the first transmission process; the base station is in the second transmission process. The data frame of the sending SIB4 is empty; the base station continuously transmits the SIB1 and the SIB2-SIB4 8 times in the third transmission process, that is, the period T2' of the base station transmitting the SIB2-SIB3 is the same as the period T1 of the base station transmitting the SIB1, and the base station transmits the SIB4. The period T2`` is twice the period T1 at which the base station transmits SIB1.

As shown in FIG. 9, on the basis of FIG. 3, the method for transmitting the SI provided by the embodiment of the present invention may further include:

S103. The base station maps the second SI to the first PDSCH, and maps downlink control information (English: downl ink control information, DCI) to the first PDSCH.

S104. The base station continuously transmits the second SI m times on the first PDSCH according to the indication of the DCI.

Alternatively, S103 may be executed first, then S102 may be performed; and S102 and S103 may be simultaneously executed.

A system information-radio network temporary identifier (S1-RNTI), and carries a DCI in the DCI fixed length portion to indicate a DCI variable length portion within the DCI interval. Specifically, if the base station needs to send the second SI to the UE, the base station may set the SI-RNTI to the first one in the UE identifier list field, and after detecting the SI-RNTI, the UE may be based on the fixed length portion of the DCI in the DCI interval.

Exemplarily, as shown in FIG. 17, the base station continuously sends the second SI to the UE in the DCI downlink burst part of the first PDSCH according to the indication of the DCI of the DCI variable length part in the DCI interval on the second PDSCH. .

As shown in FIG. 18, S103-S104 in FIG. 9 above may also be:

S103b. The base station maps the second SI to the first PDSCH.

S104b: The base station continuously sends the second SI for m times on the preset superframe on the first PDSCH; wherein the superframe number of the preset superframe (English: surper frame number, abbreviation: SFN) satisfies SFN mod (continuous transmission m period second period / DCI interval) = 0, wherein the period in which the second SI is continuously transmitted m times is an integral multiple of the DCI interval.

The embodiment of the present invention does not limit the execution order of S102 and S103b. That is, the embodiment of the present invention may first execute S102 and then execute S103b. Alternatively, S103b may be executed first, then S102 may be performed; and S102 and S103b may be simultaneously executed.

In the embodiment of the present invention, as shown in FIG. 19, when the base station sends the second SI to the UE, the base station needs to first map the second SI from the BCCH to the first PDSCH through the BCH. The BCCH is a logical channel, the BCH is a transport channel, and the first PDSCH is a physical channel.

Specifically, in the foregoing S104b, the base station may continuously send the second SI to the UE for the second time on the DCI downlink burst part in the preset superframe. The SFN of the preset superframe satisfies SFNmod (period/DCI interval of consecutive transmission of m second SIs)=0, wherein the period of continuously transmitting the second SI times is an integer multiple of the DCI interval. Illustratively, the 8X area has a DCI interval of 320 milliseconds.

Exemplarily, as shown in FIG. 20, the base station repeatedly transmits the second SI to the UE for m times on the DCI downlink burst part of the preset superframe in the first PDSCH.

In the method for transmitting the SI according to the embodiment of the present invention, the first SI is transmitted on the first PBCH, and the second SI is transmitted on the first PDSCH, so that when the content of the SI is excessive, if all the transmissions on the first PBCH are possible, The problem that the transmission period of the SI is too long may be shortened, thereby shortening the time for the UE to receive the SI, thereby saving the power consumption of the UE.

Optionally, the foregoing first PDSCH may be in a coverage area with the worst channel quality. The PDSCH can also be all PDSCHs in all coverage areas, and the invention is not limited.

Further, when the first PDSCH is the PDSCH in the coverage area with the worst channel quality, a gap (English: gap) may be configured for the UE in the connected state and needs to receive the SI based on the listening capability of the UE, to ensure that the gap is in the gap. The inner base station does not schedule data on the PDSCH in the coverage area where the UE is located, but only causes the UE to listen to the PDSCH in the coverage area with the worst channel quality to receive the second SI. The listening capability of the UE can be understood as the bandwidth size that the UE can simultaneously monitor, that is, whether the UE can simultaneously monitor the PDSCH in the coverage area in which the UE is located and the PDSCH in the coverage area with the worst channel quality.

Further, as shown in FIG. 21, when the first PDSCH is the PDSCH in all the coverage areas, it is required to ensure that the DCI fixed length portion of the DCI downlink burst portion of the second SI is transmitted within the DCI interval on each PDSCH. The superframe start points are the same, so that the UE can accurately know the superframe start point of the second SI on each PDSCH, thereby ensuring that the UE can correctly receive the second SI. At this time, the period in which the base station continuously transmits m times of the second SI is a common multiple of the DCI interval on the PDSCH in all the coverage areas. For example, in FIG. 21, the starting point (ie, the superframe starting point) of the fixed length portion of the DCI1 indicating the downstream burst portion of the DCI1 on the PDSCH1 is the same as the starting point of the fixed length portion of the DCI1 indicating the downstream burst portion of the DCI1 on the PDSCH2; PDSCH1 The starting point of the fixed length portion of the DCI 8 indicating the downlink burst portion of the DCI 8 is the same as the starting point of the fixed length portion of the DCI 2 indicating the downstream burst portion of the DCI 2 on the PDSCH 2. Assuming that the DCI interval on PDSCH1 is 320 milliseconds and the DCI interval on PDSCH2 is 640 milliseconds, the base station continuously transmits m times of the second SI period with a common multiple of 320 milliseconds and 640 milliseconds, that is, 640 milliseconds.

Optionally, in order to further save the power consumption of the UE, the UE needs to ensure that all the SIs can be received in a short time in the awake state. Therefore, as shown in FIG. 22, the base station may be configured to send the first time on the first PDSCH. The start time point of the second SI is between an end time point at which the base station transmits the first SI on the first PBCH and an end time point at which the base station transmits the first SI on the first PBCH.

As shown in FIG. 23, S103-S104 in FIG. 9 above may also be:

S103c. If n>k, the base station maps the second SI to the second PBCH.

S104c: The base station continuously transmits the second SI m times on the second PBCH.

The embodiment of the present invention does not limit the execution order of S102 and S103c, that is, the embodiment of the present invention may first execute S102 and then execute S103c; or may perform S103c first, then execute S102; and S102 and S103c may be simultaneously executed.

As shown in FIG. 24, when the base station sends the second SI to the UE, the base station needs to first map the second SI from the BCCH to the second PBCH through the BCH. The BCCH is a logical channel, the BCH is a transport channel, and the second PBCH is a physical channel.

Specifically, as shown in FIG. 25, when the second SI is specifically nk SIBs different from the first SI in the n SIBs, the foregoing S104c, that is, the base station continuously transmits the second SI times on the second PBCH, specifically Can be:

S104c1: The base station transmits n-k SIBs on m×(n-k) consecutive data frames on the second PBCH.

Specifically, in the above S104c1, the method for the base station to send n-k SIBs on the m×(n-k) consecutive data frames on the second PBCH may be one of the following:

(h) the base station continuously transmits nk SIBs on the m×(p-1)+1 data frames to the m×p data frames of m×(nk) consecutive data frames on the second PBCH The pth SIB, where p is a positive integer and p ≤ nk.

As shown in FIG. 26, it is assumed that the 8X area is taken as an example, m=8, one superframe includes 8 data frames, and the 8 data frames are sequentially numbered as data frame No. 1, data frame No. 2, ... , No. 8 data frame. The base station continuously transmits the pth of the nk SIBs on the 8th (p-1)+1th data frame to the 8xth data frame of 8×(nk) consecutive data frames on the second PBCH. SIB (ie SIBp).

Specifically, after the base station continuously transmits one SIB for m times, and then continuously transmits the next SIB for m times, and so on, when the base station sequentially sends nk SIBs in succession, that is, the base station sequentially transmits each SIB separately for m times. The base station can start the process of transmitting the next nk SIBs according to the method of (h) above. That is, the base station can periodically transmit n-k SIBs according to the method of (h) above.

The method of the foregoing (h) may facilitate the extension of the second SI, that is, when the second SI needs to be extended, the information extended in the second SI may be directly and repeatedly transmitted on the second PBCH without affecting the second SI Some information is transmitted.

(i) The base station transmits the pth SIB of the nk SIBs on the p+k×(q-1) data frames of the m×(nk) consecutive data frames, where p is a positive integer and q is Positive integer, p ≤ k, q ≤ m.

As shown in FIG. 27, it is assumed that the 8X system is taken as an example, m=8, one superframe includes 8 data frames, and 8 data frames are sequentially numbered as data frame No. 1, data frame No. 2, ... , No. 8 data frame. The base station transmits the pth SIB (i.e., SIBp) of the n-k SIBs on the p+k*(q-1)th data frames of 8×(n-k) consecutive data frames.

Specifically, after the base station transmits one SIB once, and then continuously transmits the next SIB, and so on, after the base station continuously transmits nk SIBs, the base station continuously sends the next nk SIBs, and the base station repeats m. After sending nk SIBs in succession, that is, after the base station continuously transmits nk SIBs together for m times, the base station may start the process of transmitting the next nk SIBs according to the method of (i) above. That is, the base station periodically transmits n-k SIBs according to the method of (i) above.

The method of the above (i), for a UE with a good received signal quality, if the UE correctly receives the second SI sent by the base station at least once, the UE may not continue to listen to the second PBCH to receive the second SI, thereby saving the UE. Power consumption.

In the method for transmitting the SI according to the embodiment of the present invention, the first SI is transmitted on the first PBCH, and the second SI is transmitted on the second PBCH, so that when the content of the SI is too much, if all the transmissions on one PBCH may occur, The problem that the transmission period of the SI is too long is shortened, thereby shortening the time for the UE to receive the SI, thereby saving the power consumption of the UE.

A person skilled in the art can understand that the process of transmitting the first SI/second SI by the base station is the same for each of the consecutive times. The foregoing embodiment and the corresponding figure are only that the base station continuously transmits m times of the first SI/second SI. The process is exemplified by an example. For the other processes of continuously transmitting the first SI/second SI for m times, the process of transmitting the first SI/second SI consecutively is similar to that of the above, and will not be repeated here.

Optionally, when the SI (including the first SI or the first SI and the second SI) is updated, the base station may notify the UE to update the SI. Specifically, the method for the base station to notify the UE to update the SI may be one of the following:

(1) The base station sends a paging message to the UE during the change period, and after the change period, Sending the changed SI to the UE, the paging message is used to instruct the UE to update the SI.

After receiving the paging message, the UE learns that the SI has changed according to the paging message, and updates the SI after the change period.

Since the change in SI occurs only on a specific superframe, the concept of the above-described change cycle is introduced. System information with the same content may be transmitted multiple times during a change cycle, where the change period can be defined by its schedule. The boundary of the change period is determined by the SFN, where the SFN satisfies the SFN mod change period = 0. The change period can be configured in the SI. When the base station updates the SI (or part of the SI), the base station first notifies the UE of the update, and may notify the UE in a whole change period. In the next change period, the base station sends the updated SI. After the UE receives the notification for the update, the UE acquires the updated SI from the next change period. The UE starts to use the updated SI until the UE acquires a new SI next time.

(2) The base station carries an SI change label in the first PBCH, and the SI change label is used to instruct the UE to update the SI.

When the base station updates the SI, the base station can change the value of the SI change label. For example, the base station can add 1 to the value of the original SI change label. After the UE acquires the SI change label carried in the first PBCH, the UE may determine whether the SI is updated by comparing the value of the SI change label with the value of the SI change label stored in the UE. For example, if the value of the SI change tag is different from the value of the SI change tag stored in the UE, the UE determines the SI update, so that the UE can update the SI.

Optionally, when the base station carries the SI change label in the first PBCH, the base station may carry the SI change label in the SI and send the signal to the UE; or add a new data block to the first PBCH, and change the SI The label is carried in the new data block and sent to the UE, which is not limited in the present invention.

Optionally, when the first PBCH carries the SI change label, the base station may further carry the indication information in the first PBCH, where the indication information may be used to indicate a specific one or some SI updates, that is, the UE may only use the indication information according to the indication information. Update one or some of the SIs after the update.

The method for updating the SI provided by the embodiment of the present invention can ensure that the SI is updated at the base station. After that, the UE can receive the updated SI in time and accurately, and communicate with the updated SI in time.
