Description

Information transmission method and device

Technical Field

The present invention relates to communications technologies, and in particular, to an information transmission method and apparatus.

Background

Machine Type Communication (MTC for short) is combined with the Internet, so that remote sensing and control of articles can be realized, and the combination of the Machine Type Communication and the Internet is widely applied to multiple fields of smart power grids, intelligent transportation, environmental protection, government work, public safety, smart homes, intelligent fire protection, industrial monitoring, old people nursing, personal health and the like. The MTC-based communication system includes a base station, User Equipment (UE for short), and other network elements, where information or signal transmission (transmission includes sending and receiving) is performed between the UE and the base station. Optionally, the communication system may be a Long Term Evolution (LTE) system, and may also be an Advanced LTE (LTE-a) system, or an LTE system of another future version, which is not limited in this invention.

In the LTE system, system information, Paging information, and Random Access Response (RAR) are all sent to a UE by a base station, and are called a common message; the System Information is divided into a Main Information Block (MIB) and a System Information Block (SIB). Wherein, the public message is carried through a physical channel; specifically, the MIB is carried by a Physical Broadcast Channel (PBCH), and the SIB, the RAR, and the Paging are carried by a Physical Downlink Shared Channel (PDSCH); in addition to common messages, PDSCH is also used to carry downlink unicast data; regardless of carrying common messages or Downlink unicast data, the PDSCH needs to schedule Downlink Control Information (DCI) carried by a Physical Downlink Control Channel (PDCCH) or an Enhanced Physical Downlink Control Channel (EPDCCH), that is, resource blocks occupied by the PDSCH, Modulation and Coding Scheme (MCS), and the like are configured, and further, the Transport block size (Transport block size, abbreviated as DCI) used for transmission of the SIB, the RAR, the Paging, and the Downlink unicast data can be determined by the MCS configured by the DCI. In addition, uplink data of the LTE system is carried by a Physical Uplink Shared Channel (PUSCH), and the PUSCH also needs to be scheduled by DCI, that is, a resource block occupied by the PUSCH, an MCS, and the like are configured, and further, the TBS used for uplink data transmission can be determined by the MCS configured by the DCI. Uplink Control Information (UCI) of the LTE system is carried through a Physical Uplink Control Channel (PUCCH). In the present invention, the common message, the downlink unicast data, the DCI, the uplink data, and the UCI are referred to as information in the LTE system.

In order to widely support MTC, it is necessary to reduce the complexity or cost of the UE. Reducing the reception and/or transmission bandwidth supported by a UE is one of the main techniques employed to reduce the complexity or cost of the UE. The coverage area of a cell is generally a signal transmitted by a base station with the maximum transmission power, and if a UE can correctly detect the transmitted signal with a certain probability, the location of the UE is within the coverage area of the cell. When the system supports MTC services, it is necessary to enhance the coverage (coverage) of the system, such as additional coverage enhancement of 20dB or 15dB on the basis of the coverage of the existing system. Coverage enhancement refers to the transmission of signals in the system to ensure that the UE with poor channel quality can reliably communicate with the base station. A UE that can communicate with a base station reliably with coverage enhancement is called a UE that needs coverage enhancement.

Since the bandwidth occupied by the SIB of the existing LTE system may be greater than the received signal bandwidth of the low-complexity (which may also be low-cost in the present invention) UE, the low-complexity UE cannot receive the SIB of the existing LTE system. To ensure that the low-complexity UE can communicate with the base station, it is necessary to define for the low-complexity UE: new SIB occupying no more than the received signal bandwidth of low complexity UE; in addition, the UE that needs coverage enhancement also needs to receive the new SIB; the new SIBs may be of one or more types. The first new SIB type containing configuration information needed for low complexity UEs or UEs that need coverage enhancement is e.g. MTC SIB 1.

Since the frequency range mapped by the PDCCH is the entire system bandwidth, when the system bandwidth is larger than the bandwidth of the UE with low complexity to receive signals, the UE with low complexity cannot obtain DCI for scheduling SIB through the PDCCH. In the prior art, a base station includes scheduling information of MTC SIB1 in MIB (where the frequency resource width occupied by MIB is only 1.4MHz), that is, time resource, frequency resource and MCS of MTC SIB1 are configured by MIB, so that a UE with low complexity does not need to receive DCI carried by PDCCH; the UE only needs to receive the scheduling information of the MTC SIB1 contained in the MIB and determine the MCS, the time resource and the frequency resource adopted by the MTC SIB1 according to all the scheduling information. For other information, in the prior art, the UE needs to determine the MCS (or TBS, or number of information bits) and time resource used for information transmission by receiving configuration information about the time resource and MCS sent by the base station or by blind detection.

It can be seen that, in the prior art, the base station configures the time resource, the frequency resource, and the MCS of the MTC SIB1 through the MIB, which requires a large bit overhead, and since bits in the MIB are very precious, efficient utilization is required. On the other hand, the UE needs to determine the MCS (or TBS or the number of information bits) used for information transmission, time resources, and the like by receiving the configuration information transmitted by the base station, and thus, there is a large overhead.

The embodiment of the invention is mainly applied to an LTE system, an LTE-A system or LTE systems of other future versions; alternatively, the present invention may also be applied to other communication systems that include a first entity and a second entity and that can communicate with each other, i.e. the first entity and the second entity can transmit and/or receive information. As shown in fig. 1A, the base station and the UEs 1-6 constitute a communication system in which communication is possible between the base station and the UEs 1-6; further, the UEs 4 to 6 also constitute a communication system in which the

UEs

5, 4, and 6 can communicate with each other. Optionally, the base station may be a NodeB or an evolved node b; alternatively, the UE may be any terminal, such as a low-complexity or low-cost UE, a UE requiring coverage enhancement, or a UE performing MTC, etc.

In this embodiment of the present invention, the UE determines any one of the characteristic of the information and the parameter of the information, and optionally, the any one of the attributes of the information determined by the UE is referred to as a first attribute (that is, if the UE determines the characteristic of the information, the first attribute is the characteristic of the information, and if the UE determines the parameter of the information, the first attribute is the parameter of the information). Optionally, the UE may determine the first attribute according to a random access preamble, or the UE may determine the first attribute according to configuration information of the first attribute sent by a base station, or may also determine the first attribute in another manner, which is not limited in this embodiment of the present invention.

Optionally, the characteristic of the information includes any one of: modulation coding scheme MCS, transport block size TBS and information bit number. Optionally, the parameter of the information comprises at least one of: the number of subframes required to be occupied for transmitting the information, the number of wireless frames required to be occupied for transmitting the information, the subframe number required to be occupied for transmitting the information, the subframe type required to be occupied for transmitting the information, the number or time length of symbols (optionally, the symbols may be (orthogonal frequency Division Multiplexing, OFDM) symbols) occupied for transmitting the information in a subframe, the number or time length of symbols of a downlink pilot time slot DwPTS in a special subframe of the information, the time length between a start subframe and an end subframe for transmitting the information, a coverage enhancement level, a repetition level, the number of repetitions, the number of subframes to which transmission time intervals TTI are bound, a modification period, a system information SI window length, a system information SI period, a random access response RAR window length, a discontinuous reception DRX period, a paging period, and a system bandwidth.

In the embodiment of the invention, the coverage enhancement is divided into a plurality of coverage enhancement levels according to the channel quality between the base station and the UE, or the repeated transmission of the information between the base station and the UE is divided into a plurality of repeated levels; wherein the repetition level or coverage enhancement level corresponds to a channel quality between the UE and the base station, e.g., the worse the channel quality, the higher the coverage enhancement level, or e.g., the worse the channel quality, the higher the repetition level; the coverage enhancement level of the UE or the repetition level of the information transmission may determine at least one of a number of subframes occupied by the information transmission, a number of occupied radio frames, and a number of repetitions; e.g., the higher the coverage enhancement level or the higher the repetition level, the greater the number of repetitions of the information transmission.

In the embodiment of the present invention, the UE determines, according to the determined first attribute, another one of the characteristic of the information and the parameter of the information, which is unknown to the UE, and refers to the another one as a second attribute (that is, if the first attribute determined by the UE in step S101 is the characteristic of the information, the second attribute determined by the UE in step S102 is the parameter of the information, and if the first attribute determined by the UE in step S101 is the parameter of the information, the second attribute determined by the UE in step S102 is the characteristic of the information). Optionally, the UE determines the second attribute according to the first attribute and the first association relationship; wherein the first association relationship comprises: an association between a characteristic of the information and a parameter of the information; optionally, the first association relationship is information preconfigured in the UE, or information acquired by the UE from a base station side in real time, and of course, the UE may also acquire the first association relationship in other manners, which is not limited in the present invention. Optionally, the UE may further determine a second association relationship according to the first attribute by determining a basic attribute of the second attribute; wherein the second association relationship comprises: the incidence relation between the second attribute and the basic attribute of the second attribute; further, the second attribute is determined according to the basic attribute of the second attribute and the second association relation. Optionally, the UE may also determine the second attribute by other means according to the first attribute, which is not limited in this disclosure. It can be seen that, in the embodiment of the present invention, the UE does not need to obtain all attributes of the information from the base station side, that is, the UE does not need to receive a large amount of configuration information sent by the base station through signaling to determine the relevant configuration of the information, but can determine other attributes of the information unknown to the UE according to the part of the attributes that the UE has obtained, so as to save precious resources in the signaling, that is, save system overhead.

Fig. 2 is a flowchart illustrating a second information transmission method according to an embodiment of the present invention. On the basis of the above embodiment, as shown in fig. 2, the method of the present embodiment may include:

s201, determining a first attribute in the attributes of the information; wherein the attributes of the information include: characteristics of the information and parameters of the information.

In the embodiment of the present invention, if the information is an SIB, and the SIB is a first system information block received by a UE, or an SIB that the UE needs to receive before obtaining uplink and downlink configuration and/or feature subframe configuration, the following description takes the type of the SIB as MTC SIB1 as an example. After a base station determines a first attribute in the attributes of the MTC SIB1, the base station sends a main information block MIB containing configuration information of the first attribute to the UE; and the UE receives the MIB and obtains the configuration information contained in the MIB, and further determines the first attribute according to the configuration information. Optionally, the first attribute may be any one of a characteristic of the information and a parameter of the information; that is, if the first attribute is the feature of the MTC SIB1, the configuration information of the first attribute is the configuration information of the feature of the MTC SIB 1; if the first attribute is the parameter of the MTC SIB1, the configuration information of the first attribute is the configuration information of the parameter of the mtsib 1.

Optionally, the configuration information of the first attribute is used to configure at least one of: whether subframe 1 and subframe 6 are used for transmission of the SIB, whether subframe 1 is used for transmission of the SIB, whether subframe 6 occupied by the SIB transmission is a special subframe or a downlink subframe, whether the subframe type of the SIB transmission only includes a downlink subframe or includes both a downlink subframe and a special subframe, the number of symbols occupied by the SIB in transmission of the special subframe, the length of time of the DwPTS of the special subframe used for transmission of the SIB, and the number of symbols of the DwPTS of the special subframe used for transmission of the SIB. When the cyclic prefix is a normal cyclic prefix and an extended cyclic prefix, respectively: the SIB configured by the configuration information of the same first attribute information occupies different numbers of symbols in the special subframe transmission; or the SIB configured by the configuration information of the same first attribute information occupies different time lengths in the special subframe transmission; or the DwPTS of the special subframe for SIB transmission configured by the configuration information of the same first attribute information has different time lengths; or the number of symbols of the DwPTS of the special subframe for SIB transmission configured by the configuration information of the same first attribute information is different.

Optionally, in an implementation manner of this embodiment, the base station includes one or more of the following configuration information through the MIB, and the base station sends the MTC SIB1 in subframe 1 and/or subframe 6 according to the configuration information; the UE obtains one or more of the following configuration information contained in the MIB by receiving the MIB, and the UE receives the MTC SIB1 in the subframe 1 and/or the subframe 6 according to the configuration information:

1) whether subframe 1 and subframe 6 are used for transmission of MTC SIB1, optionally, the configuration information may be 1 bit;

2) whether subframe 1 is used for transmission of MTC SIB1 and subframe 6 is used for transmission of MTC SIB1, optionally, the configuration information may be 2 bits;

3) whether subframe 6 occupied by MTC SIB1 transmission is a special subframe or a downlink subframe, optionally, the configuration information may be 1 bit;

4) the number of OFDM symbols occupied by MTC SIB1 in special subframe transmission; optionally, the configuration information is 2 bits, and is used to configure one of the number of the symbols, which is 0, 3, 7, and 9. Or, for example, the meaning of the configuration information under the normal CP and the extended CP is different, e.g., the configuration information is 3 bits. Under the normal CP, the number of the symbols is one of 1, 4, 7, 8, 9 and 10; under the extended CP, the number of the symbols is one of 1,3, 6, 7 and 8;

5) the time length of the DwPTS field of the special subframe for MTC SIB1 transmission or the number of OFDM symbols occupied by the DwPTS field. For example, the configuration information is 2 bits, and the time length for configuring the DwPTS field is 6592.

As another example, the configuration information has a different meaning under the normal CP and the extended CP, e.g., the configuration information is 3 bits. The length of time for configuring the DwPTS field under normal CP is 6592.

In the existing LTE system, the configuration of a multimedia Broadcast Multicast service single frequency Network (MBSFN) subframe is included in an SIB of SIB 2. For low complexity UEs or UEs requiring coverage enhancement, the received SIBs must be transmitted in subframes that are not configured as MBSFN subframes before the MBSFN subframe configuration is obtained. I.e. for FDD, one or more transmissions in subframes with

subframe numbers

0,4,5, 9; for TDD, one or more transmissions in subframes with

subframe numbers

0,1,5, 6. Considering the common design of FDD and TDD and that subframes with subframe numbers 0,5 are always downlink subframes for TDD, the received SIB is transmitted on subframe 0 and subframe 5 before the MBSFN subframe configuration is obtained. However, since the subframe 0 and the subframe 5 also carry synchronization signals, MIB, SIB1 in the existing system, and so on, there are very few resources available for transmitting SIB to the low complexity UE or the coverage enhancement UE, and the requirement of system coverage enhancement cannot be met. Therefore, SIBs received before the MBSFN subframe configuration is obtained need to be transmitted on other subframes as well. The types of SIBs received by the low-complexity UE or the UE requiring coverage enhancement before obtaining the MBSFN subframe configuration may be, for example, one or more of MTC SIB1, MTC SIB 2.

For TDD, in the existing LTE system, the uplink and downlink configuration and the special subframe configuration are included in the SIB of SIB 1. For low-complexity UEs or UEs requiring coverage enhancement, it is not known whether subframe 6 is a downlink subframe or a special subframe, nor is it known how long DwPTS is available for downlink transmission in the special subframe before obtaining uplink and downlink configuration and special subframe configuration. Therefore, it is a problem to be solved whether the SIB received by the low-complexity UE or the UE requiring coverage enhancement can occupy the subframe 6 before obtaining the uplink and downlink configuration and the special subframe configuration, and how long the SIB is occupied in the special subframe transmission. In the prior art, the transmission of the received SIB before obtaining the uplink and downlink configuration and the special subframe configuration adopts one or more of a fixed uplink and downlink configuration, a fixed special subframe configuration, and a fixed DwPTS time length. The SIB type received by the low complexity UE or the UE requiring coverage enhancement before obtaining the uplink and downlink configuration and the special subframe configuration may be, for example, MTC SIB 1. This approach of the prior art cannot be applied to all uplink and downlink configurations or special subframe configurations, so there may be systems in which some uplink and downlink configurations or special subframe configurations cannot be applied to support low-complexity UEs or UEs requiring coverage enhancement.

Through the above embodiment of this embodiment, the system may support multiple uplink and downlink configurations and/or special subframe configurations to perform transmission of the SIB, and has greater flexibility. Further, the system may support all uplink and downlink configurations and/or special subframe configurations for transmission of the SIB.

Optionally, the parameters of the MTC SIB1 may include one or more of the following: 1) the number of subframes occupied by the MTC SIB1, such as the number of subframes occupied by SIB transmission of MTC SIB1 (MTC SIB1 transmission for short) in a radio frame, for example, 1 to 4 subframes, or such as the number of subframes occupied by MTC SIB1 transmission in a modification period; 2) the subframe sequence number occupied by the MTC SIB1, such as one or more of 0,4,5,9 for FDD, such as one or more of 0,1,5,6 for TDD; 3) a subframe type occupied by the MTC SIB1, such as whether a subframe occupied by the MTC SIB1 is a downlink subframe, or includes both a downlink subframe and a special subframe, or such as whether an occupied subframe (e.g., subframe 6) is a downlink subframe or a special subframe; 4) the number of OFDM symbols occupied by the MTC SIB1 in a subframe, such as the number of OFDM symbols occupied by a TDD system in subframe 1 and/or subframe 6, for example, the number of symbols is one or more of 0,1,3,4, and 7; 5) the time length of the DwPTS in the special subframe occupied by the MTC SIB1, for example, the time length of the DwPTS field in the subframe 1 and/or the subframe 6 when the MTC SIB1 is transmitted in the subframe 1 and/or the subframe 6, and the time length of the DwPTS field may also be represented by the number of symbols of the DwPTS field, for example, the number of symbols of the DwPTS field is one or more of 3, 5,6, and 9; 6) a modification period, such as that of MTC SIB1, or a common modification period of SIBs that need to be received by a low complexity UE or a UE that needs coverage enhancement; 7) the system bandwidth, for example, when the system bandwidth is 1.4MHz, and the MTC SIB1 is transmitted in subframe 0 and subframe 5 with odd radio frame number, the TBS used is the first TBS; when the system bandwidth is greater than 1.4MHZ, the MTCSIB1 is transmitted in subframe 0 and subframe 5 of odd radio frame numbers, and is not transmitted in the middle 1.4MHZ of the system bandwidth, the TBS employed is the second TBS; 8) the number of radio frames occupied by the MTC SIB1, such as the number of radio frames occupied by MTC SIB1 transmission in a modification period; 9) a number of repetitions equivalent to the number of occupied subframes; 10) a repetition level; 11) a coverage enhancement level.

In the embodiment of the present invention, if the information is a system information block SIB, and the SIB is an SIB that needs to be received by the UE before obtaining the MBSFN subframe configuration (for a TDD system, the SIB may also be a SIB that needs to be received by a UE with low complexity or a UE that needs coverage enhancement after obtaining the uplink and downlink configuration and/or the special subframe configuration), the following description takes the type of the SIB as MTC SIB2 as an example, that is, N is 2. After a base station determines a first attribute in the attributes of the MTC SIB2, the base station sends system information containing configuration information of the first attribute to the UE (the system information may be MIB or MTC SIB 1); the UE receives the system information and obtains the configuration information contained in the system information, and then determines the first attribute according to the configuration information. Optionally, the first attribute may be any one of a characteristic of the information and a parameter of the information; that is, if the first attribute is the feature of the MTC SIB2, the configuration information of the first attribute is the configuration information of the feature of the MTC SIB 2; if the first attribute is the parameter of the MTC SIB2, the configuration information of the first attribute is the configuration information of the parameter of the MTC SIB 2.

Optionally, when the parameter of the information includes at least one of: when the subframe type, the number of OFDM symbols occupied by the information in the subframe (optionally, the number of OFDM symbols occupied in subframe 1 and/or subframe 6 in a TDD system), and the time length of the DwPTS in the special subframe of the information are determined, the base station and/or the UE may determine parameters of the information according to the uplink and downlink configuration and/or the special subframe configuration, for example, whether the occupied subframe 6 is a downlink subframe or a special subframe is the type of the subframe 6 configured by the uplink and downlink configuration, or for example, the time length of the DwPTS in the occupied special subframe is the time length of the DwPTS configured by the special subframe configuration, or for example, if the subframe 6 configured by the uplink and downlink configuration is a special subframe, the number of OFDM symbols occupied in the subframe 6 and/or subframe 1 is the number of symbols included in the DwPTS configured by the special subframe configuration minus the number of symbols in the conventional control region, for example, subtracting 2, or for example, if the subframe 6 configured by uplink and downlink configuration is a downlink subframe, the number of OFDM symbols occupied in the subframe 6 is the number of symbols included in one subframe minus the number of symbols in the conventional control region, such as subtracting 2; therefore, only the uplink and downlink configuration and the special subframe configuration need to be contained in the MIB and/or the MTC SIB1, and the configuration information of parameters containing the information is not needed.

Optionally, when the parameter of the information is a system bandwidth, the base station still needs to include configuration information of the system bandwidth in the MIB, and the UE determines the system bandwidth by receiving the MIB and obtaining the configuration information of the system bandwidth, so that the MTC SIB1 does not need to include the configuration information of the system bandwidth.

(3) If the information is a system information block SIB, and the SIB is an SIB that needs to be received by the UE after obtaining the MBSFN subframe configuration, (for a TDD system, the SIB may also be a SIB that needs to be received by a UE with low complexity or a SIB that needs to be received by a UE with coverage enhancement after obtaining the uplink and downlink configuration and/or the special subframe configuration), that is, the SIB is not a first SIB received by the UE and is an N-th type SIB received by the UE (N is a positive integer greater than 1), the step S201 includes: receiving any system information which is received by the UE before the SIB of the Nth type and contains the configuration information of the first attribute, and determining the first attribute according to the configuration information in the system information; wherein the system information includes at least one of: MIB and any SIBs received by the UE before receiving the Nth type of SIBs.

And each transmission (initial transmission or retransmission) occupies the number of the TTI binding subframes, namely, the same transport block or information bit is transmitted in different subframes in the TTI binding subframe number. It should be noted that, in all embodiments of the present invention, the same transport block or information bit may be transmitted in different subframes, and the same redundancy version may also be used in different subframes.

S202, determining the second attribute according to the first attribute and the first incidence relation; wherein the first association relationship comprises: an association between a characteristic of the information and a parameter of the information.

In the embodiment of the present invention, the UE determines the second attribute according to the determined first attribute and the first association relationship; wherein the first association relationship comprises: an association between a characteristic of the information and a parameter of the information; optionally, the first association relationship may be preconfigured, or may be obtained by the UE from a base station side in real time. Optionally, the first association relationship may be a one-to-one correspondence relationship, a correspondence relationship between multiple ones and one, or a correspondence relationship between multiple ones and multiple ones. Optionally, the first association relationship may be a table relationship, a proportional relationship, or another relationship, and the embodiment of the present invention is not limited.

For example, if the information is the SIB of MTC SIB1, the association between the characteristics of the information and the parameters of the information is shown in table 1. The TBS (i.e., the characteristics of the information) employed for MTC SIB1 transmission is in a one-to-one relationship with a first association of parameters of the information. Wherein a, b, c, d are fixed numerical values. Alternatively, the

columns

2 and 3 of the following table may include only one or more columns.

Table 1 is a table of the association between the characteristics of information and the parameters of information

If it is determined that the first attribute is TBS ═ a, according to the first association relationship in the table, it may be determined that the second attribute is that the number of subframes occupied by the MTC SIB1 transmitted in one radio frame is 2, the number of occupied subframes is 0 and 5, and the number of symbols in the DwPTS field in the occupied special subframe is 0.

For another example, if the information is the SIB of MTC SIB2, the association between the characteristics of the information and the parameters of the information is shown in table 2. a. b, c, d, a1, b1, c1, d1, a2, b2, c2, d2 are fixed numerical values.

Table 2 is a table of the association between the characteristics of the information and the parameters of the information

	Length of SI window	Period of SI
			TBS＝a	a1	a2
TBS＝b	b1	b2
			TBS＝c	c1	c2
TBS＝d	d1	d2

If the UE determines that the first attribute is TBS ═ a, the SI window length of the second attribute is MTC SIB2 may be determined to be a1 and the SI period is a2 according to the first association relationship in the table.

It can be seen that, in the embodiment of the present invention, the UE does not need to obtain all attributes of the information from the base station side, that is, the UE does not need to receive a large amount of configuration information sent by the base station through signaling to determine the relevant configuration of the information, but can determine other attributes of the information unknown to the UE according to the part of the attributes that the UE has obtained, so as to save precious resources in the signaling, that is, save system overhead.

S203, the information is transmitted according to the attribute of the information.

In the embodiment of the invention, a first attribute in the attributes of the information is determined; wherein the attributes of the information include: characteristics of the information and parameters of the information; determining the second attribute according to the first attribute and the first incidence relation; wherein the first association relationship comprises: an association between a characteristic of the information and a parameter of the information; further, the information is transmitted according to the attribute of the information; other attributes in the attributes of the information unknown to the UE can be determined according to the part of the attributes acquired by the UE, so that precious resources in signaling are saved, namely, system overhead is saved, and the utilization rate of system resources is improved.

Optionally, the UE blindly detects the MCS (or TBS, or number of information bits) used for MTC SIB1 transmission. For example, the UE detects MTC SIB1 with an assumed MCS for MTC SIB1 transmission. The UE determines the MCS based on the assumption. A first parameter may be determined based on the MCS and the association. Mtsib 1 may be detected according to the first parameter.

Or the UE carries out blind detection on the first parameter. For example, the UE may detect MTC SIB1 with a first parameter assumed. The UE determines the first quantity based on the assumption.
