Description

Indication method and device

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to an indication method and indication equipment.

Background

Under the condition that global mobile communication (Global System For Mobile Communications, GSM) frequency-back cannot exit from a standard bandwidth, but long term evolution (Long Term Evolution, LTE) frequency division duplex (Frequency Division Duplexing, FDD) standard bandwidth configuration, GSM shares partial frequency resources within the spectrum range of LTE to transmit GSM signals, so that the frequency spectrum utilization efficiency of FDD (frequency division duplex) can be effectively improved, namely GL frequency spectrum sharing technology is adopted, wherein GSM shared frequency points are positioned on two sides of the FDD bandwidth.

The third generation partnership project (3rd Generation Partnership Project,3GPP) specifies that enhanced machine type communication (Enhancement Machine Type Communication, eMTC) system information block-bandwidth reduction (System Information Block-Bandwidth Reduction, SIB 1-BR) must follow a frequency hopping principle, and a unique Narrowband (NB) resource block cannot be used fixedly, and the frequency hopping pattern (pattern) is based on a physical cell identity (Physical Cell Identifier, PCI), and for different PCI cells of the whole network, SIB1-BR of a part of cells may coincide with a shared GSM frequency point, resulting in a reduced SIB1-BR demodulation performance.

The 3GPP specifies that NB resource blocks used for machine type communication physical downlink control channels (Machine type communication Physical Downlink Control Channel, MPDCCH) of paging (paging) messages are PCI-based predetermined and cannot be configured based on the operator.

See tables 1 and 2, where table 1 is NB resource blocks used by SIB1-BR under different PCIs and table 2 is NB resource blocks used by paging under different PCIs.

TABLE 1

TABLE 2

In the prior art, GSM frequency points located in a shared bandwidth interfere eMTC SIB1-BR and paging messages in corresponding positions, referring to fig. 1, for example, 10MHz is shared by 10MHz and 4.4MHz is configured by LTE FDD, 50 Resource Blocks (RBs) are shared by GSM and 4.4MHz, GSM shared frequency points are symmetrically distributed on two sides of LTE bandwidth, where NB0 and NB7 all fall in the shared bandwidth, NB1 and NB6 partially fall in the shared bandwidth, and according to a test result, one GSM shared frequency point is used, and 2 to 3 RBs are respectively unavailable on two sides, i.e., NB1 and NB6 are also interfered by GSM.

SIB1-BR hops on three pairs of NB0 and NB5, NB1 and NB6, NB2 and NB7, respectively, the current solution is to reduce interference by PCI planning, PCI mod6 is not available for use with PCIs equal to 1 and 4 since NB1 and NB6 are both interfered, only 2/3 of PCI is available, and NB0 and NB5, NB2 and NB7 will be interfered in half, and demodulation performance of the terminal will be reduced.

Although MPDCCH paging may turn off or turn on hopping, since its hopping NB combination is the same as SIB1-BR, part of the paging message may still be interfered.

Referring to fig. 3, an embodiment of the present invention provides an indication method, where an execution body of the method is a network device, and specific steps of the method are as follows:

step 301: sending a first message to a terminal;

in the embodiment of the invention, the first message comprises an indication field, and the indication field is used for indicating the frequency hopping mode of the terminal.

Optionally, the first message is an enhanced machine type communication master information block (Enhancement Machine Type Communication Master Information Block, eMTC MIB) message.

Optionally, the indication field is "SIB1 orpanghopingpattern", by which the terminal is indicated whether to transmit SIB1-BR and Paging messages using the new frequency hopping pattern.

Further, when the value of the indication field is null, it indicates that the cell does not start the GL spectrum sharing function, and the terminal hops on the NB resource block corresponding to the PCI, that is, hops according to the frequency hopping pattern corresponding to the original PCI, and sends SIB1-BR and a Paging message.

When the value of the indication field is not null, the cell is indicated to start the GL spectrum sharing function, the terminal carries out frequency hopping according to the frequency hopping pattern reconfigured by the network equipment, and the new frequency hopping pattern is used for transmitting SIB1-BR and Paging information in a frequency hopping mode on the target NB resource block.

Specifically, the terminal hops on a set of target frequency hopping NB resource blocks.

In the embodiment of the invention, the NB resource blocks with available frequency hopping are determined according to the NB resource blocks of the non-coincident part of the GSM frequency band and the LTE frequency band.

If the total number of NB resource blocks in the non-overlapping portion of the GSM frequency band and the LTE frequency band is even, the number of the NB resource blocks in the frequency hopping available is the same as the total number of the NB resource blocks in the non-overlapping portion, namely the NB resource blocks in the non-overlapping portion are all the NB resource blocks in the frequency hopping available.

If the total number of NB resource blocks in the non-overlapping part of the GSM frequency band and the LTE frequency band is odd, the number of the NB resource blocks available for frequency hopping is equal to the total number of NB resource blocks in the non-overlapping part minus 1, namely one NB resource block is removed from the NB resource blocks in the non-overlapping part, and the rest NB resource blocks are the NB resource blocks available for frequency hopping. Further, one NB resource block is removed from the non-overlapping portion of the band end.

A plurality of sets of frequency hopping NB resource blocks are determined from the frequency hopping available NB resource blocks. The target set of frequency-hopping NB resource blocks is any one of the plurality of sets of frequency-hopping NB resource blocks.

Alternatively, the cell may randomly select one set from the plurality of sets of frequency-hopping NB resource blocks as the target set of frequency-hopping NB resource blocks, and the cell may select one set with less interference from the plurality of sets of frequency-hopping NB resource blocks as the target set of frequency-hopping NB resource blocks.

Optionally, the number of the plurality of sets of frequency hopping NB resource blocks is the same as the number of available frequency hopping NB resource blocks, and taking GL shared frequency bands in fig. 1 as an example, where the available frequency hopping NB resource blocks are NB2 and NB5, there are two sets of frequency hopping NB resource blocks, respectively, (NB 2, NB 5) and (NB 5, NB 2), where (NB 2, NB 5) indicates that the frequency hopping start position in the set is NB2, and where (NB 5, NB 2) indicates that the frequency hopping start position in the set is NB5.

Further, the terminal may start interval 0 from the frequency hopping start position in the set of target frequency hopping NB resource blocks, for example: the number of NB resource blocks in the target frequency hopping NB resource block set is 2, and the two NB resource blocks are adjacent; the terminal may also start to hop at interval 1 from the hop-start position in the target hop-NB resource block set, and take the GL shared band in fig. 1 as an example, since NB3 and NB4 cannot be used in this scenario, the interval between NB2 and NB5 may be regarded as 1.

It should be noted that, the terminal may cycle frequency hopping on NB resource blocks in the target set of frequency hopping NB resource blocks, for example: the NB resource blocks in the target frequency hopping NB resource block set are NB1, NB3 and NB5, frequency hopping is carried out at intervals 1 from NB1, and when the terminal hops to NB5, the terminal returns to NB1 again to start frequency hopping, so that cyclic frequency hopping is realized.

It will be appreciated that the above example of cyclic frequency hopping is only one possible example, and the embodiment of the present invention is not limited to the specific case of cyclic frequency hopping of a terminal.

Optionally, the number of NB resource blocks in each target set of frequency hopping NB resource blocks is m;

the number of NB resource blocks satisfies:

wherein,,

is the total number of downlink resource blocks;

that is, when the total number of downlink resource blocks is less than 12, the number of NB resource blocks in the set of frequency hopping NB resource blocks is 1;

when the total number of the downlink resource blocks is more than or equal to 12 and less than or equal to 50, the number of NB resource blocks in the frequency hopping NB resource block set is 2;

when the total number of downlink resource blocks is greater than 50, the number of NB resource blocks in the set of frequency hopping NB resource blocks is 4.

Further, the indication field is a hexadecimal number with a bit number less than or equal to 4 bits, and since each group of frequency hopping NB resource blocks is at most 4 NB resource blocks in the set of NB resource blocks, the 4-bit hexadecimal number is sufficient for indication. Wherein each digit indicates that the NB resource block at the corresponding position can be used in frequency hopping, and the terminal is informed of the specific position of SIB1-BR and Paging message transmission.

Referring to fig. 4, an embodiment of the present invention provides another indication method, where an execution body of the method is a terminal, and specific steps of the method are as follows:

step 401: receiving a first message from a network device;

in the embodiment of the invention, the first message is an eMTC MIB message, and the first message includes an indication field, where the indication field is used to indicate a frequency hopping manner of the terminal.

Optionally, the first message is an eMTC MIB message.

Further, when the value of the indication field is (null), it indicates that the cell does not start the GL spectrum sharing function, and the terminal hops on the NB resource block corresponding to the PCI, that is, hops according to the hopping pattern corresponding to the original PCI, and sends SIB1-BR and Paging messages.

the number of NB resource blocks satisfies:

wherein,,

is the total number of downlink resource blocks;

If the NB resource blocks of the GL shared frequency band, which are not coincident, are NB2 and NB5, the frequency hopping NB resource block sets (NB 2, NB 5) and (NB 5, NB 2) may be determined, and the indication field SIB1 orpnaginghopingern may be 0X25 or 0X52, which indicates that the terminal may hop in the target frequency hopping NB resource block set (NB 2, NB 5) or (NB 5, NB 2), respectively.

The non-coincident NB of the GL shared frequency bands is NB5, NB6, and NB7, and since NB6 is unavailable, the sets of frequency hopping NB (NB 5, NB 7) and (NB 7, NB 5) may be determined, and the indication field SIB1 orpanghopingpattern may be 0X57 or 0X75, which indicates that the terminal may hop in the target frequency hopping NB resource block set (NB 5, NB 7) or the two frequency hopping sets (NB 7, NB 5), respectively.

Optionally, if the total number of NB resource blocks in the non-overlapping portion of the GSM frequency band and the LTE frequency band is an even number, the number of NB resource blocks available for frequency hopping is the same as the total number of NB resource blocks in the non-overlapping portion;

if the total number of NB resource blocks of the non-overlapping portion of the GSM frequency band and the LTE frequency band is odd, the number of the NB resource blocks used for frequency hopping is equal to the total number of NB resource blocks of the non-overlapping portion minus 1.
