Description

[0001] The present invention relates to the field of communication technology, and in particular to an information transmission method, device, terminal and network side equipment. Background Art

[0002] In the B5 2.6GHz system, pattern 2 and pattern 3 are two possible multiplexing methods of the synchronization signal / physical broadcast channel signal block (Synchronization Signal and PBCH block, SSB) and the Type 0 physical downlink control channel (Physical downlink control channel, PDCCH). The common point of these two methods is that one SSB is mapped to one Type 0 PDCCH. In the B5 2.6GHz frequency band, since the propagation loss in the high frequency band is greater than that in the low frequency band, the coverage distance of Type 0 PDCCH in the high frequency band is much worse than that of Long Term Evolution (LTE); on the other hand, based on the characteristics of the PDCCH channel, the transmission distance of Type 0 PDCCH in the high frequency band is even smaller than that of SSB. Therefore, in pattern 2 and pattern 3, how to achieve coverage enhancement of Type 0 PDCCH is an issue that needs to be considered. Summary of the invention

[0035] The information transmission method provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0036] like Figure 2 As shown, an embodiment of the present application provides an information transmission method, including:

[0037] Step 201: The terminal obtains a first physical downlink control channel PDCCH, where the first PDCCH includes at least two PDCCH monitoring opportunities, and the first PDCCH is a PDCCH corresponding to a synchronization signal / physical broadcast channel signal block SSB.

[0038] In an embodiment of the present application, the above-mentioned first PDCCH may specifically be a Type 0 PDCCH. The Type 0 PDCCH includes a control resource set CORESET#0 and at least two search spaces (Search space) #0, and the Search space #0 is the above-mentioned PDCCH monitoring opportunity. There are three types of multiplexing between CORESET#0 and SSB, pattern 1, pattern 2 and pattern 3, wherein pattern 1 means that CORESET#0 and SSB use time division multiplexing, and pattern 2 and pattern 3 mean that CORESET#0 and SSB use frequency division multiplexing. The embodiment of the present application may use frequency division multiplexing for CORESET#0 and SSB.

[0039] Step 202: The terminal obtains downlink control information DCI for scheduling remaining minimum system information RMSI according to the at least two PDCCH monitoring opportunities.

[0040] Here, according to at least two PDCCH monitoring opportunities, DCI can be obtained, and then RMSI can be acquired according to the DCI.

[0041] In an embodiment of the present application, the first PDCCH corresponding to the SSB, such as Type 0 PDCCH, includes multiple PDCCH monitoring opportunities, through which repeated transmission of PDCCH can be achieved, such as repeated transmission of Type 0 PDCCH, thereby achieving the purpose of enhancing Type 0 PDCCH coverage.

[0042] Optionally, the at least two PDCCH listening opportunities correspond to the beam of the same SSB.

[0043] Here, at least two PDCCH monitoring opportunities correspond to the same SSB beam, thereby achieving the purpose of enhancing Type 0 PDCCH coverage in Type 2 or Type 3 of the B5 2.6 GHz system.

[0044] Optionally, the terminal acquires a first physical downlink control channel PDCCH, including:

[0045] The number of at least two PDCCH monitoring opportunities is determined by at least one of the following methods:

[0046] The number of at least two PDCCH monitoring opportunities is determined by protocol agreement;

[0047] Determine the number of the at least two PDCCH monitoring opportunities according to at least one of the subcarrier spacing of the SSB and the first PDCCH subcarrier spacing;

[0048] Determine the number of the at least two PDCCH monitoring opportunities according to an indication of a master system information block MIB; for example, indicate through an indication field of the MIB;

[0049] According to at least one of the SSB subcarrier spacing and the first PDCCH subcarrier spacing, first configuration information is determined, the first configuration information including the number of the at least two PDCCH monitoring opportunities, and the first configuration information is the configuration information of the first PDCCH.

[0050] It should be noted that the first PDCCH in the embodiment of the present application specifically refers to Type 0 PDCCH. The configuration information of the first PDCCH may specifically be a configuration table of CORESET#0 and Search space#0, and the number of the at least two PDCCH monitoring opportunities can be directly or indirectly obtained according to the configuration table.

[0051] Further optionally, determining the first configuration information according to at least one of the subcarrier spacing of the SSB and the first PDCCH subcarrier spacing includes:

[0052] The first configuration information is determined according to the ratio information of the SSB subcarrier spacing and the first PDCCH subcarrier spacing.

[0053] Optionally, the terminal acquires a first physical downlink control channel PDCCH, including:

[0054] The starting positions of at least two PDCCH monitoring opportunities are determined by at least one of the following methods:

[0055] Determine the starting positions of at least two PDCCH monitoring opportunities through protocol agreement;

[0056] According to at least one of the subcarrier spacing of the SSB and the subcarrier spacing of the first PDCCH, first configuration information is determined, wherein the first configuration information includes the starting positions of the at least two PDCCH listening opportunities, and the first configuration information is the configuration information of the first PDCCH.

[0057] Optionally, the RMSI scheduled by the DCI carried on each of the PDCCH monitoring opportunities is the same.

[0058] Here, the RMSI scheduled by the DCI carried on each PDCCH monitoring opportunity is the same, and demodulation accuracy can be improved by demodulating multiple DCIs together.

[0059] The RMSI scheduled by the DCI carried on each PDCCH monitoring opportunity is different.

[0060] Here, the RMSI scheduled by the DCI carried on each of the PDCCH monitoring opportunities is different, and the DCIs on the at least two PDCCH monitoring opportunities need to be demodulated together to obtain all RMSI information.

[0061] Further optionally, when the RMSI scheduled by the DCI carried on each of the PDCCH monitoring opportunities is the same:

[0062] The positions of the time domain resources indicated by the DCI carried on different PDCCH monitoring opportunities are different;

[0063] Alternatively, the first DCI carries all information required for scheduling RMSI, and each second DCI carries only indication information of time domain resources required for scheduling RMSI;

[0064] The first DCI is one of the DCIs carried on the at least two listening opportunities, and the second DCI is the DCI other than the first DCI carried on the at least two listening opportunities.

[0065] In an embodiment of the present application, when the RMSI scheduled by the DCI carried on each of the PDCCH listening opportunities is the same, the positions of the time domain resources indicated by the DCI carried on different PDCCH listening opportunities are different, while the other resources indicated by the DCI carried on different PDCCH listening opportunities are the same. Alternatively, the first DCI carries all the information required for scheduling the RMSI, and each second DCI only carries the indication information of the time domain resources required for scheduling the RMSI, and it is assumed that the other indication fields of each second DCI are the same as the first DCI.

[0066] The information transmission method of the present application is described below in conjunction with specific embodiments.

[0067] Embodiment 1: For the case of type 2, the PDCCH subcarrier spacing is 4 times the SSB subcarrier spacing.

[0074] For example, SSB0 corresponds to two PDCCH slots, namely PDCCH slot2 and PDCCH slot3; the first slot in the PDCCH slots corresponding to SSB0 is PDCCH slot2, and the second slot in the PDCCH slots corresponding to SSB0 is PDCCH slot3.

[0075] like Figure 3As shown, each SSB may correspond to multiple PDCCHs (two in the figure). And the two PDCCHs may be in the same slot or in different slots.

[0090] The time slot where the PDCCH monitoring opportunity is located can be at least one of the first time slot in the PDCCH time slot corresponding to the i-th SSB and the first time slot + 1 in the PDCCH time slot corresponding to the i-th SSB. "And / or" in Table 3 means that the PDCCH monitoring opportunity can be in the same time slot or in different time slots.

[0091] like Figure 5 As shown, each SSB may correspond to multiple PDCCHs (two in the figure). And the two PDCCHs may be in the same slot or in different slots.

"And / or" in Table 4 means that the PDCCH monitoring opportunity can be in the same time slot or in different time slots.

[0099] like Figure 6As shown, each SSB may correspond to multiple PDCCHs (three in the figure). And the two PDCCHs may be in the same slot or in different slots. The data scheduled by each PDCCH is located in different slots.
