Description

Information transmission method, base station and terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an information transmission method, a base station, and a terminal.

Background

Mf (multimedia fire) is a radio access technology that extends Long Term Evolution (LTE) technology to unlicensed frequency bands, and the technology can independently operate in unlicensed spectrum without using licensed frequency band carriers. In order to fairly occupy the unlicensed band channel and avoid mutual interference between other devices in the unlicensed band (e.g., WiFi devices), the MF physical layer introduces a Listen-Before-Talk (LBT) mechanism of carrier sensing technology similar to WiFi. 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.

Mf (multimedia fire) organization sets up a research on an unlicensed frequency band enhanced machine type communication (eMTC) technology, that is, eMTC-U, which is introduced into an unlicensed frequency band. The eMTC-U is a frequency modulation system working at 2.4GHz, 56 frequency hopping frequency points are provided in total, the bandwidth of each frequency hopping frequency point is 1.4MHz (approximately accounting for 80MHz in total), the longest service time of a base station and a terminal for sending downlink/uplink at one frequency hopping frequency point is 75ms, a base station sends a 5ms pilot channel (the pilot channel is fixed and unchanged) in the middle of two frequency hopping, and thus the total frequency hopping period including the pilot channel, the uplink and downlink switching time and the channel switching time is 80 ms. And the base station needs to perform channel access detection (LBT) every time the base station jumps to a new frequency point, the maximum channel occupation time of the base station is 60ms after the LBT is successful, and the base station still needs to send downlink data and needs to perform the LBT again if the maximum channel occupation time exceeds 60 ms.

According to the existing eMTC technology, the number of retransmissions of an SIB1-BR message may be 4, 8, or 16 per narrowband System Information Block1 (SIB 1-BR) period, and in order to achieve a greater coverage enhancement effect in the eMTC-U System, the number of retransmissions of an SIB1-BR may be 32. The SIB1-BR begins transmission in the first hop period of the scheduling period, which the terminal must go through to resolve the SIB1-BR, resulting in too large a delay for the terminal to receive the SIB 1-BR. Another phenomenon is that since other System messages cannot be transmitted in the same subframe as the SIB1-BR in the eMTC-U, according to the prior art, the transmission window of the narrowband System Information (SI-BR) must be larger than the number of repeated transmissions of the SIB1-BR (for example, if the number of repeated transmissions of the SIB1-BR is 32, the SI-BR window must be selected to be larger than 32ms), and if all repeated SIB 1-BRs are transmitted in the same hopping period, the SI-BR transmission window is increased, which results in an excessive delay in the terminal receiving the System Information.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings.

As shown in fig. 1, an embodiment of the present invention provides an information transmission method, which is applied to a base station, and includes:

step 101: and acquiring a scheduling period of system broadcast information and the repeated transmission times of the system broadcast information in the scheduling period.

The System broadcast Information may include a narrowband System Information Block 1(System Information Block1 of Bandwidth Reduction, SIB1-BR) and one or more narrowband System Information (SI-BR);

wherein the narrowband system information SI-BR contains one or more System Information Blocks (SIBs) of system information block 2 to system information block 19.

The step 101 specifically includes: and respectively sending system broadcast information belonging to the same scheduling period on at least two working frequency points of the data channel according to the repeated transmission times.

Step 102: and if the scheduling period is greater than a system frequency hopping period, respectively sending the system broadcast information on at least two working frequency points of a data channel according to the repeated transmission times, wherein the system frequency hopping period is a time interval for replacing the working frequency points of the data channel.

In the specific embodiment of the invention, the system broadcast information can be repeatedly transmitted for many times in a scheduling period, each transmission occupies one downlink DL subframe, each narrow-band system information SI-BR has a corresponding system information transmission Window (SI-Window), and each SI-BR is transmitted in the DL subframe in the corresponding transmission Window. The scheduling period of the SI-BR is configured to the terminal by the SIB1-BR and can be one of 80ms, 160ms, 320ms, 640ms, 1280ms and 2560ms, and the scheduling period of the SIB1-BR is configured to the terminal by the SIBA or the MIB and can be one of 80ms, 160ms, 320ms and 640 ms. The repeated transmission times in one scheduling period of the SIB1-BR are configured to the terminal by the SIBA or the MIB, and the repeated transmission times in the scheduling period of the SI-BR are configured to the terminal by the base station through the SIB 1-BR.

Specifically, the base station acquires a scheduling period of the system broadcast information and the number of times of repeated transmission in the scheduling period, and means that the base station configures the scheduling period of the system broadcast information and the number of times of repeated transmission of the system broadcast information in the scheduling period, and directly acquires the scheduling period of the system broadcast information and the number of times of repeated transmission in the scheduling period, so that repeated transmission of the system broadcast information is transmitted in a plurality of frequency hopping periods of at least two working frequency points of a data channel, and the plurality of frequency hopping periods are uniformly distributed or are sequentially adjacent in the scheduling period. The terminal acquires the repeated transmission of the system broadcast information sent in the multiple frequency hopping periods of the at least two working frequency points of the data channel through the configuration information of the base station, so that the repeated transmission of the system broadcast information is received in the multiple frequency hopping periods.

And after acquiring the scheduling period of the system broadcast information and the repeated sending times in the scheduling period, the base station sends the relevant configuration information to the terminal. Taking SIB1-BR for repeated transmission over multiple frequency hopping periods as an example, in order for a terminal to receive SIB1-BR at a corresponding downlink subframe, the base station may configure the scheduling period of SIB1-BR and the number of repeated transmissions within the scheduling period to the terminal from SIBA or MIB, and further may configure the number of repeated transmissions of SIB1-BR over the frequency hopping period within the scheduling period, or the number of frequency hopping periods during which SIB1-BR is transmitted within the scheduling period, or the number of frequency hopping periods spaced during which SIB1-BR is transmitted within the scheduling period from SIBA or MIB to the terminal; optionally, the base station may configure, by the SIBA or the MIB, the number of times of repeated transmission of the SIB1-BR in a hopping period within the scheduling period, the number of hopping periods during which the SIB1-BR is transmitted within the scheduling period, or the number of hopping periods at intervals during which the SIB1-BR is transmitted within the scheduling period, to the terminal.

Taking repeated transmission of the SI-BR in a plurality of frequency hopping periods as an example, in order to facilitate the terminal to receive the SI-BR in a corresponding downlink subframe, the base station can configure the scheduling period of the SI-BR and the repeated transmission times in the scheduling period to the terminal through SIB1-BR, and further configure the repeated transmission times of the SI-BR in the frequency hopping period in the scheduling period, the number of frequency hopping periods for transmitting the SI-BR in the scheduling period, or the number of frequency hopping periods spaced for transmitting the SI-BR in the scheduling period to the terminal through SIB 1-BR; preferably, the base station may configure, by the SIB1-BR, the number of repeated transmissions of the SI-BR in a hopping period within the scheduling period, and the number of hopping periods during which the SI-BR is transmitted within the scheduling period or the number of hopping periods spaced during which the SI-BR is transmitted within the scheduling period to the terminal, where if the base station configures a size of a transmission window of the SI-BR (for example, the transmission window of the SI-BR is configured to the terminal through the SIB1-BR), the number of repeated transmissions of the SI-BR in the hopping period may be indicated by a repeated transmission pattern of the SI-BR, where the repeated transmission pattern includes: the method comprises the steps of transmitting the SI-BR once in the first available subframe of r radio frames in a transmission window of the SI-BR, wherein r is a positive integer, or continuously transmitting the SI-BR in the first available subframe of the transmission window of the SI-BR.

In the embodiment of the invention, the base station respectively sends the system broadcast information belonging to the same scheduling period on a plurality of working frequency points, so that the terminal with better signal quality can demodulate the system broadcast information through one frequency hopping period, the problem of overlarge system broadcast information receiving delay caused by the fact that the base station repeatedly sends the system broadcast information belonging to the same scheduling period in the same frequency hopping period is solved, and the system performance is improved.

As a first optional implementation manner, the step 102 of, according to the number of times of retransmission, respectively sending, by the base station, system broadcast information belonging to the same scheduling period on at least two working frequency points of the data channel includes:

and sending system broadcast information belonging to the same scheduling period on L working frequency points of the data channel according to the repeated transmission times, wherein the L data channels are uniformly distributed in the scheduling period, and L is a positive integer greater than or equal to 2.

The system broadcast information may specifically include SIB1-BR or SI-BR, which is described below with SIB1-BR as an example. Specifically, if the number of times of repeated transmission of the system broadcast information is greater than or equal to the number of times of frequency hopping in the scheduling period, determining the number of times of repeated transmission k1, k1 being P/Q of the system broadcast information in each frequency hopping period of the scheduling period, P being the number of times of repeated transmission of the system broadcast information in the scheduling period, and Q being the number of times of frequency hopping in the scheduling period.

In this case, the base station only needs to configure the total number of transmission times of the SIB1-BR to the terminal. As shown in FIG. 2, assuming that the SIB1-BR repeating transmission number P is 8, the hop period is 80ms, and the SIB1-BR scheduling period is 320ms, the frequency of hopping Q in the scheduling period is 4, and the base station transmits SIB1-BR 2 times (P/Q) in each hop period.

If the repeated transmission times of the system broadcast information are less than the frequency hopping times in the scheduling period, determining to send the system broadcast information once in the kth 2 frequency hopping period of the scheduling period;

wherein k2mod N is 0 and N is Q/P.

For example, if the number P of repeated transmissions of the SIB1-BR is 4, the scheduling period of the SIB1-BR is 640ms, the frequency hopping number Q in the scheduling period is 8, the base station transmits 1SIB1-BR in the k2 th frequency hopping period in the scheduling period, N is 2, and k2 satisfies that k2mod 2 is 0, that is, one SIB1-BR is transmitted every 2 frequency hopping periods.

Further, if the number of times that the base station repeatedly sends the system broadcast information in the frequency hopping period is m, m is a positive integer;

the step of sending the system broadcast information belonging to the same scheduling period on the L working frequency points of the data channel according to the repeated transmission times includes:

transmitting m times of system broadcast information on a k3 th frequency hopping period of the scheduling period;

where k3mod (Q/(P/m)) ═ 0.

The system broadcast information may specifically include SIB1-BR or SI-BR, and assuming that the system broadcast information is SIB1-BR, and the number of times that the base station repeatedly transmits SIB1-BR in a hopping period in which the SIB1-BR is transmitted in a SIB1-BR scheduling period is defined as m, when the SIB1-BR is uniformly transmitted in one SIB-BR scheduling period, the method for the base station to select the hopping period for transmitting the SIB1-BR is as follows: the SIB1-BR is transmitted m times on the k3 th hopping period within the scheduling period, where k3 satisfies k3mod (Q/(P/m)) -0. For example, as shown in fig. 3, if the number P of repeated transmissions of SIB1-BR is 8, the scheduling period of SIB1-BR is 320ms, the number Q of hops in the scheduling period is 4, and the number m of repeated transmissions in a predetermined hop period is 4, it is necessary to transmit SIB1-BR 4 times in 2(P/m) hop periods, and k3 satisfies k3mod (2) being 0 in k3 hop periods in the scheduling period. In this case, the base station needs to configure the UE with the number m of times of repeatedly transmitting SIB1-BR in the hopping period in which SIB1-BR is transmitted in the scheduling period, in addition to configuring the total number of times of repeated transmission of SIB1-BR in the scheduling period to the UE. As an optional implementation manner, the base station configures m to the terminal through a spare bit of schedulingInfoSIB1-BR in the MIB, or configures m to the terminal through a spare bit of SIB-a.

As a second optional implementation manner, if the number of times that the base station repeatedly sends the system broadcast information in the frequency hopping period is m, and m is a positive integer, the step 102 is a step of sending, by the base station, the system broadcast information belonging to the same scheduling period on at least two working frequency points of the data channel according to the number of times of repeated transmission, and includes:

according to the repeated transmission times and m, system broadcast information belonging to the same scheduling period is sent on k4 working frequency points of a data channel, wherein k4 working frequency points are uniformly distributed in the scheduling period; or

And sequentially sending system broadcast information belonging to the same scheduling period on k4 working frequency points of a data channel according to the repeated transmission times and m, wherein k4 is P/m.

Wherein m is one of 1, 2, 4, 8, 16, and 32, and m is less than or equal to the total number of repetitions of transmission in the scheduling period. In addition to configuring the total repeated transmission times of the SIB1-BR to the terminal, the base station needs to configure m to the terminal.

At this time, the base station needs to transmit the repeated SIB1-BR over (P/m) hopping periods of the scheduling period.

The base station can uniformly send the repeated transmission of the SIB1-BR in one SIB-BR scheduling period, and can also send the repeated transmission of the SIB-BR in sequence on a frequency hopping period. If the repeated transmission of the SIB1-BR is uniformly transmitted in one SIB-BR scheduling period, m times of SIB1-BR is transmitted in the ith hop period in the scheduling period, wherein i satisfies i mod (Q/(P/m)) -0. If the base station repeatedly sends SIB1-BR in the hopping frequency period in sequence, the base station sends repeated SIB1-BR in the 1 st to (P/m) th hopping frequency periods. As shown in fig. 4, when the total number P of repeated transmission of SIB1-BR is 8, the scheduling period of SIB1-BR is 320ms, the number Q of hopping frequencies in the scheduling period is 4, and the number m of repeated transmission in a predetermined hopping period is 4, the base station needs to transmit the SIB1-BR repeated in 2(P/m) hopping periods in sequence. The base station configures m to the terminal through a spare bit of schedulingInfoSIB1-BR in the MIB, or configures m to the terminal through a spare bit of SIB-A.

As a third optional implementation manner, if the base station sends the system broadcast information on s frequency hopping periods within the scheduling period, where s is a positive integer, step 102 is a step of sending, by the base station, the system broadcast information belonging to the same scheduling period on at least two working frequency points of the data channel according to the number of times of repeated transmission, and includes:

repeatedly sending P/s-time system broadcast information on each frequency hopping period in s frequency hopping periods according to the repeated transmission times and s;

and the s frequency hopping periods are uniformly distributed in the scheduling period or are s frequency hopping periods which are adjacent in sequence in the scheduling period.

The system broadcast information may specifically include SIB1-BR or SI-BR, and assuming that the system broadcast information is SIB1-BR, the base station needs to configure s to the terminal. In this transmission case, the base station needs to repeatedly transmit (P/s) times the SIB1-BR at each of s hopping periods of the scheduling period.

The base station also needs to configure the total number P of times of repeated transmission of SIB1-BR or directly configure the number P/s of times of repeated transmission of SIB1-BR in each hop period in s hop periods to the terminal, so that the terminal can receive SIB1-BR in P/s downlink subframes in each hop period in s hop periods.

The base station can uniformly transmit SIB1-BR in one SIB1-BR scheduling period, and can also repeatedly transmit SIB1-BR in sequence on a frequency hopping period. If the SIB1-BR is uniformly transmitted in one SIB1-BR scheduling period, the SIB1-BR is transmitted (P/s) times in the t-th hop period in the scheduling period, where t satisfies t mod (Q/s) ═ 0. If the base station sequentially sends SIB1-BR in the frequency hopping period, the base station sends repeated SIB1-BR in the 1 st to s-th frequency hopping periods. As shown in fig. 4, when the total number P of repeated transmissions of SIB1-BR is 8, the SIB1-BR scheduling period is 320ms, the number Q of hopping frequencies in the scheduling period is 4, the number s of hopping periods for transmitting SIB1-BR in the scheduling period is defined to be 2, 4(P/s) times of SIB1-BR need to be transmitted in each hopping period, and the base station repeats transmission of SIB1-BR in 2 hopping periods in sequence. The base station can configure s to the terminal through a spare bit of schedulingInfoSIB1-BR in the MIB, or can configure s to the terminal through a spare bit of SIB-A.

If the base station sends the system broadcast information every n frequency hopping periods in the scheduling period, where n is a positive integer, then, as a fourth optional implementation manner, the step 102 is a step of sending, by the base station, the system broadcast information belonging to the same scheduling period on at least two working frequency points of the data channel according to the number of times of repeated transmission, and includes:

repeatedly sending P/(Q/n) times of system broadcast information in the k5 th frequency hopping period according to the repeated transmission times and n; where k5mod n is 0.

N is specifically 1, 2, 4 or 8. The base station transmits SIB1-BR in the k5 th hop period of the scheduling period, k5 satisfies k5mod n being 0, and the number of repetitions of the base station transmitting SIB1-BR in the k5 th hop period is P/(Q/n). In this case, the base station needs to indicate the hop period for transmitting the SIB1-BR within the scheduling period to the terminal, i.e., configure n to the terminal. The base station configures n to the terminal through the idle bit of schedulingInfoSIB1-BR in the MIB, or configures n to the terminal through the spare bit of SIB-A. The base station also needs to configure the total number of times P of repeated transmission of SIB1-BR or the number of times P/(Q/n) of repeated transmission of SIB1-BR in the hopping period directly to the terminal, so that the terminal receives SIB1-BR in the P/(Q/n) downlink subframes of the k5 th hopping period of the scheduling period.

It should be noted that, the above four optional implementations are also applicable to the SI-BR, and if the base station configures the size of the transmission window of the SI-BR (for example, configures the transmission window of the SI-BR to the terminal through SIB1-BR), the number of times of repeated transmission of the SI-BR in the above hopping period may be indicated by a repeated transmission mode of the SI-BR, where the repeated transmission mode includes: the method comprises the steps of transmitting the SI-BR once in the first available subframe of r radio frames in a transmission window of the SI-BR, wherein r is a positive integer, or continuously transmitting the SI-BR in the first available subframe of the transmission window of the SI-BR.

In an embodiment of sending SI-BRs in multiple frequency hopping periods of a scheduling period, the step 102 of sending system broadcast information belonging to the same scheduling period on at least two working frequency points of a data channel according to the number of repeated transmissions includes:

and transmitting the narrow-band system information belonging to a scheduling period in a transmission window of the narrow-band system information (SI-BR), wherein the transmission window of the narrow-band system information is positioned in a frequency hopping period corresponding to at least two working frequency points of the data channel.

In the embodiment of the invention, the system broadcast information can be repeatedly transmitted for a plurality of times in a scheduling period, each transmission occupies one DL subframe, each SI-BR has a corresponding system information transmission Window (SI-Window), and each SI-BR is transmitted in the DL subframe in the corresponding transmission Window. The scheduling period of the SI-BR is configured to the terminal by the SIB1-BR, and can be one of 80ms, 160ms, 320ms, 640ms, 1280ms and 2560 ms. The repeated transmission times in the scheduling period of the SI-BR are configured to the terminal by the base station through the SIB 1-BR.

After acquiring a scheduling cycle of system broadcast information and repeated sending times in the scheduling cycle, a base station sends repeated transmission of the system broadcast information in a plurality of frequency hopping cycles of at least two working frequency points of a data channel, wherein the plurality of frequency hopping cycles are uniformly distributed or are adjacent in sequence in the scheduling cycle.

Specifically, if the base station sends narrowband system information on s hopping periods within a scheduling period, s is a positive integer; the step of transmitting the narrowband system information belonging to one scheduling period within the transmission window of the narrowband system information includes:

repeatedly transmitting the P/s times of narrowband system information in the transmitting window of each frequency hopping period in s frequency hopping periods according to the repeated transmission times and s;

Wherein s is specifically one of 1, 2, 4, 8, 16, and 32, and s is less than or equal to the number of hopping periods in one SI-BR scheduling period, that is, the transmission window of the SI-BR is located in s hopping periods of the scheduling period, and the base station configures s to the terminal.

In this transmission case, the base station needs to repeatedly transmit (P/s) times the SI-BR in each of s hop periods of the scheduling period, and the base station configures the number of times of repeated transmission P in the scheduling period or the number of times of repeated transmission (P/s) on the hop period to the terminal (the base station may indicate the number of times of repeated transmission of the SI-BR on the hop period by the repeated transmission pattern of the SI-BR), so that the terminal receives the repeated transmission of the SI-BR in (P/s) downlink subframes of the corresponding hop period. The base station can uniformly send the SI-BR in one SI-BR scheduling period, that is, the sending windows of the SI-BR are uniformly distributed in the scheduling period, and can also sequentially send the SI-BR in the hopping frequency period, that is, the sending windows are sequentially positioned in a plurality of hopping frequency periods. If the SI-BR is uniformly transmitted in one SI-BR scheduling period, transmitting (P/s) times of the SI-BR in the u-th hopping period in the scheduling period, wherein u satisfies u mod (Q/s) ═ 0. As shown in fig. 5, the total number of repeated transmissions P of an SI-BR is 8, a transmission window is 20ms, and an SI-BR scheduling period is 320ms, then the number of hopping frequencies Q in the scheduling period is 4, the number s of hopping periods for transmitting the SI-BR in the scheduling period is specified to be 2, then each hopping period needs to transmit the SI-BR 4(P/s), the transmission windows of the SI-BR are uniformly distributed in the scheduling period, and a base station uniformly transmits the SI-BR in the scheduling period (each transmission window transmits 4 SI-BRs). And if the base station sequentially sends the SI-BR in the frequency hopping period, the base station sends repeated SI-BR in the 1 st to s-th frequency hopping periods. As shown in fig. 6, if the total number of repeated transmissions P of an SI-BR is 8, the scheduling period of the SI-BR is 320ms, the number of hopping frequencies Q in the scheduling period is 4, and the number s of hopping periods for transmitting the SI-BR in the scheduling period is 2, 4(P/s) times of transmission of the SI-BR is required in each hopping period, the transmission window of the SI-BR is located in the first 2 hopping periods, and the base station sequentially transmits the SI-BR in 2 hopping periods (4 times of transmission of the SI-BR per transmission window). The base station configures s to the terminal through a spare bit of schedulingInfoSIB1-BR in the MIB, or configures s to the terminal through a spare bit of SIB-A.

Specifically, if the base station sends narrowband system information every n hopping periods within a scheduling period, n is a positive integer; the step of transmitting the narrowband system information belonging to one scheduling period within the transmission window of the narrowband system information includes:

repeatedly sending the P/(Q/n) times of narrowband system information in a sending window of a k6 th frequency hopping period according to the repeated transmission times and n; where k6mod n is 0.

Where n is specifically 1, 2, 4, 8, 16 or 32, and n is less than or equal to the number of hopping periods in the SI-BR scheduling period. The base station transmits the SI-BR in the k6 th frequency hopping period of the scheduling period, k6 satisfies that k6mod n is 0, and the repetition number of the transmission of the SI-BR in the k6 th frequency hopping period by the base station is P/(Q/n). In this case, the base station needs to indicate the position of the repeated transmission of the SI-BR in the scheduling period to the terminal, that is, n is configured to the terminal, and configure the number of repeated transmissions P in the scheduling period or the number of repeated transmissions P/(Q/n) (the base station may indicate the number of repeated transmissions of the SI-BR in the above-mentioned hopping period by the repeated transmission pattern of the SI-BR) to the terminal. The base station configures n to the terminal through the idle bit of schedulingInfoSIB1-BR in the MIB, or configures n to the terminal through the spare bit of SIB-A.

Meanwhile, the base station indicates the mode of sending the system broadcast information to the terminal.
