Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

The first embodiment,

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

step 101: determining a second type of broadcast channel different from the first type of broadcast channel; the first type broadcast channel is used for providing system information for at least N first type electronic devices, and the second type broadcast channel is used for providing resource management information for M second type electronic devices; the first type of electronic equipment supports a first bandwidth and a bandwidth smaller than the first bandwidth, and the second type of electronic equipment only supports a second bandwidth smaller than the first bandwidth; n and M are positive integers greater than or equal to 1;

step 102: generating resource management information for the second type of electronic device;

step 103: mapping the resource management information to the second type of broadcast channel;

step 104: and sending the resource management information to the M second-class electronic devices through the second-class broadcast channel, so that the M second-class electronic devices access resources for the second-class electronic devices according to the resource management information.

Here, the first broadcast channel may be a Physical Broadcast Channel (PBCH) and is mainly used for carrying system Information, i.e., a Management Information Block (MIB), and the update period of the first broadcast channel is 40ms and the period of repeated transmission of Information is 10 ms. In the time domain, PBCH is transmitted in slot 1 of subframe 0, and in the frequency domain, PBCH occupies 1.25M of frequency bandwidth.

In this embodiment, the first type of electronic device may be a common mobile terminal; the first bandwidth may be 20M, and generally, the first type of electronic device may support generally supported communication bandwidths of 1.4M, 5M, 10M, 15M, 20M, and so on.

The second type of electronic device may be a Machine Type Communication (MTC) terminal; accordingly, the second bandwidth is only 1.4M.

The second type broadcast channel only transmits resource management information for a second type of electronic equipment; the resource management information may be an access resource location of the second type of electronic device.

Therefore, by adopting the scheme, the second type broadcast channel special for the second type electronic equipment can be determined, the resource management information for the second type electronic equipment is mapped to the second type broadcast channel and is sent to the second type electronic equipment. Therefore, the second type of electronic equipment can search and acquire the resource management information in a targeted manner, and the complexity of the search information of the second type of electronic equipment is reduced.

Example II,

The determining of the second type of broadcast channel different from the first type of broadcast channel may include: determining at least one Resource Element (RE) having the same frequency domain and a different time domain as the first type of broadcast channel as the second type of broadcast channel.

Where the RB is a resource of 12 consecutive carriers in the frequency domain (180K in the case of a 15K carrier interval) and one slot in the time domain (half a subframe, 0.5 ms). The RE is 1 subcarrier in the frequency domain and occupies one symbol in the time domain. One RB may contain 84 REs.

The first broadcast channel may be a Physical Broadcast Channel (PBCH) and is mainly used for carrying system Information, i.e., a Management Information Block (MIB), and the update period of the first broadcast channel is 40ms and the period of repeated transmission of Information is 10 ms. In the time domain, PBCH is transmitted in slot 1 of subframe 0, and in the frequency domain, PBCH occupies 1.25M of frequency bandwidth.

The second type of broadcast channel may be transmitted in subframe 0, slot 1, and a position occupying a different symbol from the PBCH, where the same bandwidth is occupied by the PBCH in the frequency domain.

Fig. 2 shows a division relationship between the first type broadcast channel and the second type broadcast channel in the time domain, where the second type broadcast channel may occupy the last three symbols in the time slot 1, and in the frequency domain, occupy the position located in the center of the bandwidth. In fig. 2, the lowest end is given as 12 RBs of the central frequency band in two slots of one subframe, RB positions occupying the first four symbols in the time domain in 6 RBs in the second slot are used for bearing the first type of broadcast channel, and RB positions occupying the last three symbols in the time domain in 6 RBs in the second slot are used for bearing the second type of broadcast channel; wherein, the resource unit occupied by the second type broadcast channel is 214 REs.

Example III,

Preferably, since the MIB message carried on the PBCH has a vacant position of 10 bits, the first type broadcast channel may further indicate whether the base station supports communication of the second type electronic device on the original PBCH, specifically, as shown in fig. 3, the method further includes:

step 301: generating first indication information, wherein the first indication information is used for representing whether the base station supports communication of the second type of electronic equipment;

step 302: adding the indication information to the system information to obtain new system information;

step 303: mapping the new system information to the first type of broadcast channel;

step 304: and sending the first indication information to the M second-class electronic devices and the N first-class electronic devices through the first-class broadcast channel.

The first indication information may be an identifier, for example, "1" may be set to indicate that the base station supports communication of the second type of electronic device, and "0" may be set to indicate that the base station does not support communication of the second type of electronic device; assuming that the second type of electronic device is an MTC terminal, the following statements "MTC _ supported expected { yes, no }, (size (1)))" may be added to the MIB carried by the PBCH. When the second-type communication equipment is accessed to a communication network, acquiring an MIB from a first-type broadcast channel after receiving the first-type broadcast channel, analyzing first indication information from the MIB, and when the first indication information is 1, continuously acquiring resource management information from the received second-type broadcast channel; when the first instruction information is 0, the processing flow is ended.

Example four,

Where the RB is a resource of 12 consecutive carriers in the frequency domain (180K in the case of a 15K carrier interval) and one slot in the time domain (half a subframe, 0.5 ms). The RE is 1 subcarrier in a frequency domain, occupies one symbol in a time domain, and may have different numbers of RBs corresponding to one slot in different first bandwidths according to the size of the first bandwidth, where when the first bandwidth is 20MHz, 100 RBs may be included in one slot, and when the first bandwidth is 15MHz, 75 RBs may be included in the first slot. One RB may contain 84 REs.

Preferably, based on the above scheme, the specific manner for generating the resource management information for the second type of electronic device is further provided in this embodiment, and includes:

The communication resource of the second type of electronic equipment is set according to the first bandwidth supported by the base station. For example, as shown in fig. 4, assuming that the first bandwidth is 20MHz, 214 REs in slot 1 in time-domain subframe 0 at the center of the frequency domain are the locations of the second type broadcast channels 40; when the first bandwidth is 20MHz, the last 3 symbols in the slot 1 of the subframe 0 in the time domain, and the bandwidth of each 1.4MHz in the frequency domain are communication resources for the second type of electronic device, such as one communication resource 41 for the second type of electronic device in the figure, and in addition, the resource positions marked by the shaded parts in fig. 4, except for the second type of broadcast channel 40, can be divided into communication resources for the second type of electronic device.

It can be understood that the example in this embodiment only gives a division diagram when the first bandwidth is 20M. In actual use, when the first bandwidth is 10MHZ, the division is performed according to the same division method as described above, but the number of the division is smaller than that of the communication resources for the second type of electronic devices shown in fig. 4. The correspondence between the first bandwidth and the corresponding amount of communication resources for the second type of electronic device may be as shown in table 1 below:

TABLE 1

In addition, a numbering rule for the location of the communication resource of the second type of electronic device may also be preset in the base station and the second type of electronic device, specifically: setting the position of the second type of broadcast channel as the position of No. 0 resource; the directions of the frequency domain increase from the position of the second type broadcast channel are sequentially set by step 2, for example, in fig. 4, resource positions No. 2, 4, 6, 8, 10, 12, and 14 are sequentially set from the second type broadcast channel 40 upward, and then the number of the position 41 of the communication resource for the second type electronic device may be No. 14; from the direction of the decrease in the frequency domain at the position of the second type broadcast channel, the first one is set as the resource position No. 1, and then the resource positions are sequentially increased by taking 2 as a stepping value.

The length of the second indication information may correspond to the number of communication resources for the second type of electronic device, for example, the number of communication resources for the second type of electronic device shown in fig. 4 is 15, and assuming that the second indication information is indicated by using one bit for each communication resource of the second type of electronic device, the first bit is used for indicating the communication resource for the second type of electronic device corresponding to the 0 th number, the second bit is used for indicating the communication resource for the second type of electronic device corresponding to the 1 st number, and so on. When the second indication information is 0, it may indicate that the corresponding location does not have the resource allocated to the second type of electronic device, and when the second indication information is 1, it may indicate that the corresponding location has the resource allocated to the second type of electronic device.

Example V,

Preferably, different from the fourth embodiment, another way of generating the resource management information for the second type of electronic device is provided in this embodiment, and includes:

It can be understood that the example in this embodiment only gives a division diagram when the first bandwidth is 20M. In actual use, when the first bandwidth is 10MHZ, the division is performed according to the same division method as described above, but the number of the division is smaller than that of the communication resources for the second type of electronic devices shown in fig. 4. The correspondence between the first bandwidth and the corresponding amount of communication resources for the second type of electronic device may be as shown in table 1.

The length of the second indication information may correspond to the number of communication resources for the second type of electronic device, and assuming that the second indication information is indicated using two bits for each communication resource of the second type of electronic device, the first and second bits are used to indicate the communication resource corresponding to the number 0 for the second type of electronic device, the third and fourth bits are used to indicate the communication resource corresponding to the number 1 for the second type of electronic device, and so on.

In this embodiment, the usage degree indicates whether the number of the second type of electronic devices currently served by the communication resources of the second type of electronic devices exceeds a first threshold, or whether the number of the second type of electronic devices currently served by the communication resources of the second type of electronic devices is lower than a second threshold;

when the current usage degree of the communication resources for the second type of electronic equipment is busy, the first threshold value is exceeded;

when the current usage degree of the communication resources for the second type of electronic equipment is normal, the current usage degree of the communication resources for the second type of electronic equipment is not exceeded by the first threshold value and is exceeded by the second threshold value;

when the second threshold value is not exceeded, the usage level of the communication resources for the second type of electronic equipment is indicated as idle.

The first threshold and the second threshold may be set according to actual situations, for example, if the total number M of the second type of electronic devices managed by the base station is 20, the first threshold may be set to 18, and the second threshold may be set to 5.

The meaning represented by every two bits in the second indication information in this embodiment may be as shown in table 2:

TABLE 2

For example, as shown in fig. 5, assuming that the bits 1 to 8 in the second indication information are "00011011", the first two bits "00" indicate that the communication resource for the second type of electronic device is allocated at the position 0; thereafter, "01" indicates that at position No. 1, communication resources for the second type of electronic device are allocated and the degree of use is free; "10" indicates that the communication resource for the second type of electronic device is allocated at the position No. 2, and the usage level is normal; "11" indicates that at position No. 3, the communication resource for the second type electronic device is allocated and the usage level is busy. Therefore, by setting the use degree, the second type of electronic equipment can acquire the condition of each communication resource, so that the second type of electronic equipment can access the resource which ensures to provide better service.
