Description

Processing method, communication equipment and storage medium

Technical field

This application relates to the field of communication technology, and specifically to a processing method, communication equipment and storage medium.

Background technique

With the development of 5G technology, in order to reduce costs and meet more detailed needs, considering the balance between cost and performance, reduced capability (Redcap, Reduced Capability) terminals are proposed, which are mainly suitable for enhanced mobile broadband (eMBB, enhanced Application scenarios for bandwidth, power consumption, cost and other requirements between Mobile Broadband) and Low-Power Wide-Area (LPWA, Low-Power Wide-Area) networks. Discussions about Redcap technology believe that reducing or limiting the UE bandwidth to such as 10M/5MHz will bring about some backward compatibility issues. For example, most control resource set (CORESET) #0 configurations in FR1 may not be supported.

On the one hand, under reduced bandwidth, the maximum aggregation level supported by CORESET#0 is 4, so insufficient coverage may occur in some scenarios. Therefore, it is necessary to increase the number of resources occupied by CORESET#0 to ensure cell edge coverage. On the other hand, when the subcarrier spacing of CORESET#0 is 30KHz, the number of resource blocks (RBs) occupied by it is at least 24 according to the existing protocol, but the maximum number of RBs under the 5MHz bandwidth is 11, so it will As a result, the current bandwidth cannot meet the initial access bandwidth requirements of CORESET#0. Therefore, it is also necessary to improve the design of CORESET#0, the synchronization signal/physical broadcast channel (Physical Broadcast Channel, PBCH) block (Synchronous signal/PBCH Block, SSB) and the multiplexing mode of CORESET#0.

The preceding description is intended to provide general background information and does not necessarily constitute prior art.

Although the above introduction takes the LTE system as an example, those skilled in the art should know that this application is not only applicable to the LTE system, but also can be applied to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA and future new Network systems (such as 5G), etc. are not limited here.

Based on the above-mentioned mobile terminal hardware structure and communication network system, various embodiments of the present application are proposed.

In order to facilitate understanding of the processing method provided by the embodiment of this application, the Control Resource Set (CORESET) is introduced below:

In 5G NR, CORESET is a set of physical resources in a specific area in the downlink resource grid, used to carry downlink control information (Downlink Control) in the Physical Downlink Control Channel (PDCCH) Information, DCI). Among various CORESETs, CORESET#0 is used for the scheduling of System Information Block 1 (SIB1), which will be involved in the initial cell search process. As mentioned above, the reduced/limited bandwidth affects the number of resources occupied by CORESET#0. For example, the number of resources is lower than the required level. This may cause problems of insufficient initial access bandwidth and/or insufficient coverage. Therefore, the above problem can be solved at least by improving the configuration/instruction of resource allocation for CORESET#0.

Based on the above description, in order to effectively increase the number of resources occupied by the control resource set when the bandwidth is limited, thereby improving the insufficient initial access bandwidth and/or insufficient coverage, the present application provides a processing method, communication device and storage medium. The processing method, communication device and storage medium provided by the embodiments of the present application are further described in detail below.

Figure 3 is a schematic flowchart of an information processing method provided by an embodiment of the present application. As shown in Figure 3, the information processing method at least includes the following steps S301 to S304. The method execution subject shown in Figure 3 may be a terminal device (for example, the mobile terminal 100 of Figure 1 or the UE 201 of Figure 2). Alternatively, the method execution subject shown in Figure 3 may be a chip in the terminal device. Figure 3 takes the terminal device as the execution subject of the method as an example for illustration.

S301: Receive first instruction information, and the first instruction information satisfies preset conditions.

In this embodiment of the present application, the first indication information may be received by the terminal device from the network device, and the first indication information may be a Main Information Block (MIB). As a MIB, the first indication information can be obtained on the PBCH channel, and can include at least the configuration corresponding field pdcch-ConfigSIB1 of CORESET#0, the configuration corresponding field dmrs-typeA-position of the first demodulation reference signal, etc. The high 4-bit index (index) of the pdcch-ConfigSIB1 field of the MIB indicates CORESRT#0, including the number of RBs in the frequency domain and the number of symbols in the time domain that it occupies. The dmrs-typeA-position field of the MIB indicates the symbol position of the Demodulation Reference Signal (DMRS) of the corresponding Physical Downlink Shared Channel (PDSCH). The specific indication method will be detailed below. narrate.

In this embodiment of the present application, the first indication information indicates the resource information of the control resource set corresponding to the physical downlink control channel, and/or the frequency domain offset between the synchronization signal block and the control resource set, for example, through the pdcch of the MIB -ConfigSIB1 field to indicate. Optionally, the first indication information also indicates the index of the starting symbol of the first demodulation reference signal, for example, indicated by the dmrs-typeA-position field of the MIB.

In this embodiment of the present application, the first indication information satisfying the preset condition may mean that the information/parameter indicated by the first indication information satisfies the preset condition. More details about the preset condition will be described in detail below.

S302: According to the first indication information, receive the physical downlink control channel.

In this embodiment of the present application, after receiving the first indication information, the terminal device may decode further information from the first indication information, for example, obtain the pdcch-ConfigSIB1 field, etc. Then, the terminal equipment may receive the PDCCH based on further information decoded from the first indication information.

In a possible implementation, the terminal device can obtain the pdcch-ConfigSIB1 field from the first indication information as MIB, and pass the field (such as , its high 4-bit index) to obtain resource information about CORESRT#0, as shown in Table 1, including the multiplexing mode of SS/PBCH block (SSB) and CORESET#0, the number of occupied RBs, and the occupied symbols number and the frequency domain offset (in RB) of SSB from CORESET#0. Then, the terminal equipment can allocate time domain and/or frequency domain resources to CORESET #0 based on the information of CORESET #0 in order to receive the PDCCH corresponding to CORESET #0, as shown in Figures 4 to 7 that will be described in detail later. shown.

Table 1 RB set and slot symbol set of CORESET#0 when the SCS of SSB and PDCCH are both 15KHz (minimum channel bandwidth 5MHz)

It should be noted that if the coverage of edge users is improved when the bandwidth is limited/reduced, it is necessary to increase the number of resources occupied by the control resource set (referred to as CORESET#0 in this application). In this case where the frequency domain bandwidth has been limited, it is necessary to consider increasing the number of time slot symbols occupied by CORESET#0. Therefore, the indication of resource information related to CORESET#0 (for example, as shown in Table 1) also needs to be improved accordingly. Moreover, under the same bandwidth, the number of RBs occupied by CORESET#0 with different subcarrier spacing (SCS) will also be different. Therefore, it is also necessary to consider how to improve CORESET under different subcarrier spacing of a given bandwidth. Indication of #0 related resource information (such as PDSCH).

In this embodiment of the present application, the first indication information (for example, MIB) that satisfies the preset conditions may refer to the indication information that satisfies the above resource allocation (also called resource information), that is, the indication of the relevant resources of CORESET#0 The information can meet the following requirements: effectively increase the number of resources occupied by CORESET#0 in the case of limited bandwidth so as to improve the initial access bandwidth shortage and/or coverage shortage.

In a possible implementation, in step S301, satisfying the preset condition includes at least one of the following: the first indication information indicates resource information of the control resource set corresponding to the physical downlink control channel; The number of symbols occupied by the control resource set in the time domain is greater than or equal to the first preset value; the number of resource blocks occupied by the control resource set in the frequency domain indicated by the first indication information is any one of the preset values. The technical features of the preset conditions are described in detail below from three aspects: resource information of the control resource set, and specific first preset values and preset value sets.

(1) Meeting the preset conditions includes the first indication information indicating the resource information of the control resource set corresponding to the physical downlink control channel:

In this embodiment of the present application, the resource information of the control resource set corresponding to the physical downlink control channel indicated by the first indication information may include at least one of the following: the time domain location of the control resource set, the frequency domain location of the control resource set and control the subcarrier spacing of the resource set. The time domain location of the control resource set may include the radio frame in the time domain where the control resource set is located (for example, the index of the radio frame) and/or the number of symbols occupied by the time domain of the control resource set. The frequency domain position of the control resource set may include the frequency domain starting position of the control resource set (for example, the index of the resource block at the starting position), the number of resource blocks occupied by the frequency domain of the control resource set, and/or the synchronization signal block and the control resource set. Frequency domain offset between resource sets (e.g., in number of resource blocks). In addition, the subcarrier spacing configuration of the control resource set may be expressed in an index form corresponding to the value of the subcarrier spacing.

Of course, the time domain location of the control resource set, the frequency domain location of the control resource set, and the subcarrier spacing of the control resource set may also include other relevant information and/or be expressed in other forms. The above are only examples, and the application is not limited thereto. .

In one implementation, when the resource information of the control resource set corresponding to the physical downlink control channel indicated by the first indication information includes the time domain position of the control resource set, the frequency domain position of the control resource set and a sub-section of the control resource set. When at least one of the carrier intervals is present, the preset conditions are met. For example, it can be preset as needed: when the resource information of the control resource set contains specific information or what conditions the specific information satisfies, the preset conditions are met. For example, satisfying the preset condition may mean that the resource information of the control resource set includes the starting position of the control resource set in the frequency domain. Of course, the present application is not limited to this. For example, satisfying the preset conditions may also be as described in (2)(3) below.

(2) Meeting the preset conditions includes controlling that the number of symbols occupied by the time domain of the resource set is greater than or equal to the first preset value:

In this embodiment of the present application, the number of symbols occupied by the control resource set in the time domain is greater than or equal to the first preset value may mean that the number of symbols occupied by the control resource set in the time domain is compared with the number specified by the existing protocol (for example, , 1, 2 or 3 slot symbols) is increased, and accordingly, the first preset value may be 1, 2 or 3.

Optionally, the first preset value may be configured as 3. Since CORESET#0 in the existing protocol usually occupies 1 to 3 time slot symbols, when the preset condition is met, which means that the number of symbols occupied by the time domain of the control resource set is greater than 3, CORESET#0 in the existing protocol The mapping table no longer applies. In the embodiment of this application, for this scenario, a new resource mapping table for CORESET#0 is proposed to cover the situation where the number of symbols occupied by CORESET#0 in the time domain is greater than 3. For example, Table 1 above adds resource information to include the case where the number of symbols occupied by CORESET#0 time domain is 4, as shown in bold numbers in Table 1, that is, indexes 6-8 correspond to CORESET#0 The number of symbols occupied by the time domain is 4.

As described above, Table 1 shows the resource information when the maximum number of symbols occupied by the CORESET#0 time domain is 4. However, the present application is not limited to this, and may also provide a table of resource information corresponding to when the maximum number of symbols occupied by the CORESET#0 time domain is greater than 4.

Optionally, Table 2 below shows resource information in which the maximum number of symbols occupied by CORESET#0 in the time domain is X, where X is a positive integer. As shown in bold numbers in Table 2, Table 2 includes resource information for more cases where the number of symbols occupied by the CORESET#0 time domain is greater than 4.

Table 2 RB set and slot symbol set of CORESET#0 when the SCS of SSB and PDCCH are both 15KHz (minimum channel bandwidth 5MHz, increase the number of index bits)

In one implementation, assuming that CORESET#0 starts from the starting position of the timeslot, the value of When X is less than 14, CORESET#0 and PDSCH may or may not be in the same time slot; ii) When At 14, if the value of X mod 14 is less than 14, this corresponds to case i), and if the value of The impact on PDSCH scheduling of whether CORESET#0 and PDSCH are in the same time slot will be further described in detail below.

Optionally, the number of bits indicating the index of CORESET#0 in the pdcchConfigSIB1 field can be modified from 4 to 5 to indicate resource information for more situations in which the number of symbols occupied by CORESET#0 in the time domain is greater than 7 (X≥7) ,As shown in table 2.

Optionally, the 4-bit pdcchConfigSIB1 field can also be used without increasing the number of index bits. For example, the configuration of resource information can be further improved in the case of a 4-bit index, as shown in Table 3 below (as shown in bold numbers in the table) As shown), this improvement is sufficient when the number of symbols occupied by CORESET#0 is not high.

Table 3 When the SCS of SSB and PDCCH are both 15KHz, the RB set and slot symbol set of CORESET#0 (minimum channel bandwidth 5MHz, no increase in the number of index bits)

(3) Meeting the preset conditions includes controlling that the number of resource blocks occupied by the frequency domain of the resource set is any one of the preset values:

In this embodiment of the present application, the preset value set may be the number of resource blocks under different channel conditions (for example, given different bandwidths and subcarrier intervals). In this case, if the number of resource blocks occupied by the frequency domain of the control resource set indicated by the first indication information satisfies the preset condition (that is, it is any item in the preset value set), it can indicate that the number of resource blocks occupied by the frequency domain resources of the control resource set satisfies the preset condition. Change (for example, decrease) in the number of resource blocks occupied.

Optionally, the preset value set can be configured as {6, 12, 24}. Generally, when the SCS is 15KHz, the 5MHz bandwidth supports up to 24 RBs according to the typical transmission bandwidth configuration. When the SCS is increased to 30KHz, according to the typical transmission bandwidth configuration, the 5MHz bandwidth corresponds to 11 RBs. Therefore, considering the limited system bandwidth, the number of frequency domain RBs can be selected within a limited preset range (such as a preset value set). For example, consider that any number can be selected from the preset value set {6, 12, 24}. One item is the number of RBs used for CORESET#0 transmission with SCS of 15KHz or 30KHz under 5MHz bandwidth. However, the preset value set {6, 12, 24} is only an example. The preset value set may also include one or more other values according to actual needs, and the application is not limited thereto.

Optionally, when the SCS of the PDCCH corresponding to CORESET#0 is 30KHz and the number of RBs occupied by it in the frequency domain is 6 in the preset value set {6, 12, 24}, the corresponding resource information is as shown in Table 4 .

Table 4 RB set and slot symbol set of CORESET#0 when the SCS of SSB and PDCCH are 15KHz and 30KHz respectively (minimum channel bandwidth 5MHz)

Optionally, when the SCS of the PDCCH corresponding to CORESET#0 is 30KHz and the number of RBs occupied by CORESET#0 in the frequency domain is 6, the number of symbols occupied by CORESET#0 in the time domain can be increased as shown in Table 1-Table 3. . For example, the number of symbols occupied by the CORESET#0 time domain can be increased to 4 or other values to ensure the available resources of CORESET#0 under the 5MHz bandwidth, as shown in Table 5 below:

Table 5 RB set and slot symbol set of CORESET#0 when the SCS of SSB and PDCCH are 15KHz and 30KHz respectively (minimum channel bandwidth 5MHz)

Optionally, satisfying the preset condition includes controlling the number of resource blocks occupied by the resource set in the frequency domain to be any one of the preset values. The number of resource blocks occupied by the control resource set in the frequency domain is used to determine the frequency domain offset reference value. , the frequency domain offset reference value is used to determine the frequency domain offset between the synchronization signal block and the control resource set; optionally, the frequency domain offset reference value S is:

Among them, R represents the number of resource blocks occupied by the frequency domain of the control resource set, and μ represents the subcarrier spacing configuration of the control resource set. In this embodiment of the present application, the correspondence between the value of the subcarrier spacing configuration μ and the value of the subcarrier spacing Δf is as shown in Table 6 below. Table 6 Correspondence between the value of subcarrier spacing configuration μ and the value of subcarrier spacing

μμ	Δf＝2 ^μ·15[kHz] Δf＝ ^2μ ·15[kHz]
00	1515
11	3030
22	6060

33	120120
44	240240
55	480480
66	960960

In this embodiment of the present application, the frequency domain offset between the synchronization signal block and the control resource set may be a function of a fixed value and the frequency domain offset reference value S. For example, the frequency domain offset may be the sum of the fixed value and the frequency domain offset reference value S. However, the present application is not limited thereto. The frequency domain offset may also be determined based on other algorithms based on the fixed value and the frequency domain offset reference value S. In this embodiment, the fixed value may be selected from a fixed value set. For example, the fixed value set is {-2,0,2} or {-2,-1,1,2}. In this embodiment, the fixed value set may be related to the subcarrier spacing of SSB and CORESET#0. For example, when the subcarrier spacing of SSB and CORESET#0 are both configured as 15KHz, the fixed value set may be configured as {-2 ,0,2}, then the value of frequency domain offset is: S+{-2,0,2}. For example, when the subcarrier spacing of SSB and CORESET#0 is configured as 15KHz and 30KHz respectively, the fixed value set can be configured as {-2,-1,1,2}, then the value of the frequency domain offset is: S+ {-2,-1,1,2}. Among them, the frequency domain offset reference value S can be determined according to formula (1).

An example of determining the frequency domain offset based on the fixed value and the frequency domain offset reference value S as described above can be given by the following Table 7 and Table 8. The symbol number column in Table 7 and Table 8 is only illustrative, and the application is not limited thereto. The value of the symbol number column can be changed according to the method given in this application (for example, the method as mentioned above). In Table 7 and Table 8, the offset (RB) represents the frequency domain offset between the synchronization signal block and the control resource set.

Table 7 RB set and slot symbol set of CORESET#0 when the SCS of SSB and PDCCH are both 15KHz (minimum channel bandwidth 5MHz)

Table 8 RB set and slot symbol set of CORESET#0 when the SCS of SSB and PDCCH are 15KHz and 30KHz respectively (minimum channel bandwidth 5MHz)

In a possible implementation, for example, based on Table 4 or Table 5 or Table 7 or Table 8, receiving the physical downlink control channel in step S302 of the method may include: according to the frequency domain position of the synchronization signal block , at least one of the frequency domain offset between the synchronization signal block and the control resource set (for example, indicated by the first indication information) and the number of resource blocks of the control resource set, determines the frequency domain position of the control resource set.

It should be noted that the above considers the possible mappings that the time domain mapping and frequency domain mapping of CORESET#0 need to satisfy in the scenario where the number of symbols occupied by CORESET#0 in the time domain increases and/or the number of RBs occupied by the frequency domain decreases. rule. The impact of the increase in the number of CORESET#0 symbols on the resource allocation of the PDSCH that may be brought about will be further considered below. In particular, the resource allocation of the DMRS on the PDSCH needs to be considered. The following will introduce the time domain mapping position of DMRS indicated by the dmrs-typeA-position field included in the first indication information (for example, MIB).

In the embodiment of the present application, as mentioned above, the first indication information (for example, MIB) can indicate the index (l ₀ ) of the starting symbol of the first DMRS through the dmrs-typeA-position field. The first DMRS refers to The first DMRS of PDSCH in the time domain (also called PDSCH DMRS).

In a possible implementation, the index of the starting symbol of the first DMRS is the first identifier or the second identifier.

In this embodiment of the present application, the index (l ₀ ) of the start symbol of the first DMRS may be indicated by the dmrs-typeA-position field as "pos2" (first identifier) or "pos3" (second identifier).

Optionally, the values of "pos2" and "pos3" can be fixed values. For example, dmrs-typeA-position='pos2' can indicate that the value of l ₀ is 2, and dmrs-typeA-position='pos3' can indicate that the value of l ₀ is 3.

In the embodiment of the present application, one of "pos2" and "pos3" can be selected to indicate l ₀ according to actual needs (such as the number of symbols occupied by the CORESET#0 time domain, etc.). For example, when the number of CORESET#0 symbols is less than 3, the network device configures dmrs-typeA-position='pos2'; when the number of CORESET#0 symbols is greater than or equal to 3, the network device configures dmrs-typeA-position='pos3' .

Optionally, "pos2" and "pos3" can also take other values, for example, they can change according to actual needs (such as channel conditions). For example, when the Reference Signal Received Power (RSRP) reaches the first preset threshold (for example, indicating that the channel condition is good enough), the network device configures dmrs-typeA-position='pos2'; when the RSRP is lower than the first For two preset thresholds (for example, indicating that channel conditions are not good enough) or in terminal deployment scenarios, the network device configures dmrs-typeA-position='pos3'. However, these cases are only examples, and the application is not limited thereto.

It should be noted that after the position of the starting symbol of the first DMRS is obtained as described above, the resource information of the PDSCH carrying the first DMRS also needs to be determined.

As shown in Figure 3, in a possible implementation, the method may also include:

S303 (shown by the dotted line in Figure 3): Receive the second indication information. The second indication information indicates at least one of the following of the physical downlink shared channel: an index of a starting symbol, a symbol length, and a time slot offset from the physical downlink control channel.

In this embodiment of the present application, step S303 may be performed before, after, or simultaneously with step S301, and the present application is not limited thereto. The second indication information may be received by the terminal device from the network device, and the second indication information may be downlink control information (DCI). As the DCI, the second indication information may be obtained on the PDCCH channel, and may at least include a configuration corresponding field for time domain resource allocation of the PDSCH, a time domain resource assignment field (Time domain resource assignment). This field can provide an index (row index) to indicate (for example, according to dmrs-typeA-position) relevant information of time domain resource allocation of PDSCH, as shown in Table 9 or Table 10, including PDSCH mapping type (for example, TypeA or TypeB ), the index of the starting symbol of PDSCH (S, in symbol units), the symbol length of PDSCH (L, in symbol units), the slot offset between PDSCH and the corresponding PDCCH (K ₀ , in slots number as unit).

Table 9 and Table 10 are examples assuming that the number of symbols occupied by CORESET#0 is 4. Table 9 is for the case of normal cyclic prefix (Cyclic Prefix, CP), and Table 10 is for the case of extended CP.

Table 9 Default PDSCH time domain resource allocation for normal CP A

Table 10 Default PDSCH time domain resource allocation for extended CP A

Note 1: When dmrs-TypeA-Position=3 ("pos3"), whether S is 3 or 4 depends on whether the number of symbols in CORESET#0 is 3 or 4.

How to determine the index of the starting symbol of the first DMRS according to the dmrs-TypeA-Position field in the first indication information (MIB) is further described with reference to Table 9 and Table 10. As mentioned before, the index of the starting symbol of the first DMRS can be indicated by the dmrs-TypeA-Position field as the first identifier or the second identifier, that is, "pos2" (or "2" in the table) or "pos3 ” (or “3” in the table). In addition, under the condition that CORESET#0 does not conflict with the first DMRS, the first identifier ("pos2") and/or the second identifier ("pos3") can be flexibly defined, and one of them can be flexibly selected. Index indicating the starting symbol of the first DMRS. Based on this understanding, the first identifier and/or the second identifier are described in detail below.

Optionally, when the value of the time slot offset between CORESET#0 and PDSCH is 0 and/or the number of symbols occupied by the CORESET#0 time domain is less than or equal to 2, the first identifier ("pos2") The value can be 1 or 2. Optionally, when CORESET#0 and PDSCH are in the same timeslot and the number of symbols occupied by CORESET#0 time domain is less than or equal to 2, dmrs-TypeA-Position can take the first identifier "pos2", and "pos2" The value can be 1 or 2. Optionally, when CORESET#0 and PDSCH are in the same time slot, and the number of symbols occupied by CORESET#0 in the time domain is less than or equal to 2, the first identifier ("pos2") takes a fixed value of 2. Optionally, when CORESET#0 and PDSCH are in the same timeslot and the number of symbols occupied by CORESET#0 time domain is less than or equal to 2, the first identifier ("pos2") can be flexibly interpreted as 1 or 2, for example: When the number of symbols occupied by CORESET#0 in the time domain = 1, "pos2" indicates that the starting symbol index of the first DMRS of PDSCH is 1; when the number of symbols occupied by CORESET#0 in the time domain = 2, "pos2" The starting symbol index indicating the first DMRS of the PDSCH is 2.

Optionally, when the number of symbols occupied by the CORESET#0 time domain is greater than 3, the value of the second identifier ("pos3") may be the number of symbols occupied by the CORESET#0 time domain. For example, when CORESET#0 and PDSCH are in the same time slot and the number of symbols occupied by CORESET#0 time domain is greater than or equal to 3, dmrs-TypeA-Position takes the second identifier "pos3", and the value of "pos3" It can be the number of symbols occupied by the CORESET#0 time domain. For example, when CORESET#0 and PDSCH are in the same time slot and the number of symbols occupied by CORESET#0 time domain is 4, "pos3" indicates that the starting symbol index of the first DMRS of PDSCH is 4.

Optionally, when the index (S) of the starting symbol of PDSCH is greater than the number of symbols occupied by CORESET#0, the value of the second identifier ("pos3") may be the number of symbols occupied by CORESET#0 in the time domain. and the maximum value in the index (S) of the starting symbol. For example, when CORESET#0 and PDSCH are in the same time slot and the index (S) of the starting symbol of PDSCH is greater than the number of symbols occupied by CORESET#0 in the time domain, dmrs-TypeA-Position takes the second identifier "pos3", And the value of "pos3" can be the maximum value among the number of symbols occupied by CORESET#0 in the time domain and the index (S) of the starting symbol of PDSCH. For example, when CORESET#0 and PDSCH are in the same time slot, and the number of symbols occupied by "pos3" CORESET#0 time domain is 3 and the index (S) of the starting symbol of PDSCH is 4, the value of "pos3" is max{3,4}=4, that is, the index of the first DMRS is 4.

Optionally, when the value of the timeslot offset between CORESET#0 and PDSCH is not 0, it can be determined based on the channel conditions (such as the value of RSRP) that the value of dmrs-TypeA-Position is the first identifier ( "pos2") or the second identifier ("pos3"). Moreover, the value of "pos2" can be 0 or 1 or 2, and the value of "pos3" is 3. That is to say, when the PDCCH and PDSCH corresponding to CORESET#0 are not in the same time slot, the determined value of "pos2" is determined according to the actual terminal deployment scenario. For example, the fixed value of "pos2" is 0.

In summary, the definition and/or selection of the first identifier and the second identifier are not limited to the above optional situations and/or examples, and other definitions/selections may also be made depending on the situation.

In this embodiment of the present application, the combination of the index (S) and the symbol length (L) of the PDSCH starting symbol in the time slot indicated by the second indication information should be valid, for example, should be feasible.

Optionally, taking the maximum number of symbols of CORESET#0 as 4 as an example, the effective combination values of S and L are given in Table 11.

Table 11 Valid S and L combinations

Optionally, according to the number of symbols occupied by different CORESET#0 time domains, set a mapping table that conforms to certain rules between the PDSCH starting symbol and the symbol length occupied in a time slot, and use the number of symbols of CORESET#0 The maximum value is 4 as an example. For effective combinations of the index (S) and symbol length (L) of the PDSCH starting symbol in the slot, see Table 9 and Table 10. Table 9 is for normal CP, and Table 10 is for Extended CP.

Optionally, taking the maximum number of symbols of CORESET#0 as X (X is a positive integer) as an example, the effective combination values of S and L are given in Table 12.

Table 12 Valid S and L combinations

Please refer to Figure 4. Figure 4 is a schematic diagram of an example resource allocation of a downlink control channel and a downlink shared channel according to an embodiment of the present application. It is described as follows in conjunction with the method of the present application.

Optionally, Figure 4 shows the time domain resource allocation when CORESET#0 and PDSCH are in the same time slot (K ₀ =0). In the example of Figure 4, the symbol of the PDSCH is based on one RB in the frequency domain (optionally, the case of multiple RBs in the frequency domain is the same as the frequency domain distribution of one RB), and the first preset value is 2.

The resource allocation shown in Figure 4 can be obtained according to the method proposed in this application.

First, in step S301, receive the MIB (first indication information) and obtain the index value of the CORESET#0 mapping in the field pdcch-ConfigSIB1. In this example, the index value is 6. As shown in Table 1, the time domain occupied by CORESET#0 The number of symbols is 4 and is greater than or equal to the first preset value 2, that is, the received first indication information satisfies the preset conditions. According to the frequency domain offset and frequency domain position of SSB and CORESET#0 in Table 1, The frequency domain range of CORESET#0 is determined based on the number of occupied RBs, and then the PDCCH is received in step S302.

Secondly, in step S301, the value of the field dmrs-TypeA-Position can also be obtained from the received MIB (first indication information). In this example, dmrs-TypeA-Position='pos3', and the meaning of 'pos3' is CORESET #0 The number of symbols occupied by the time domain, and assuming that the CP type is NCP, the DMRS configuration type is typeA and the DMRS is single symbol, then DCI (second indication information) can also be received in step S303, and according to the Time The domain resource assignment field corresponds to Row index = 2 and field dmrs-TypeA-Position = 'pos3'. From Table 9, it can be seen that the starting symbol of PDSCH is S = 4, and the symbol duration occupied by PDSCH is L = 8. Therefore, in step S302, receiving the PDCCH according to the first indication information that satisfies the preset condition may include: receiving the PDCCH and the PDSCH associated with the PDCCH according to the first indication information and the second indication information that satisfy the preset condition. .

As shown in Figure 4, in the time domain, the first 4 symbols in the timeslot shown are used to receive PDCCH, the last 8 symbols are used to receive PDSCH, and the DMRS of PDSCH starts from the 5th of the timeslot (i.e. Index 4) symbol starts.

Please refer to Figure 5. Figure 5 is a schematic diagram of an example resource allocation of downlink control channels and synchronization signal blocks according to an embodiment of the present application. It is described as follows in conjunction with the method of the present application.

Optionally, FIG. 5 shows a schematic diagram of determining the frequency domain position of CORESET#0 according to the frequency domain offset between SSB and CORESET#0. In the example of Figure 5, assuming that the channel bandwidth is 5MHz, the SCS of CORESET#0 is 30KHz, the SCS of SSB is 15KHz, and the preset value set of the number of RBs occupied by CORESET#0 in the frequency domain is {6, 12, 24} , as shown in Table 4.

The resource allocation shown in Figure 5 can be obtained according to the method proposed in this application.

First, in step S301, receive the MIB (first indication information) and obtain the value of the field pdcch-ConfigSIB1. In this example, pdcch-ConfigSIB1 is 2. At the same time, according to Table 4, you can know the number of RBs occupied by the CORESET#0 frequency domain. is 6, and belongs to the preset value set {6, 12, 24}, that is, the received first indication information satisfies the preset condition. Then, in step S302, the PDCCH can be received according to the information obtained from the MIB.

Secondly, in step S301, the frequency domain offset between CORESET #0 and SSB and the time domain symbol number and time domain position of CORESET #0 can also be obtained from the received MIB (first indication information). In this example, the obtained frequency domain offset of SSB and CORESET#0 is -3 RBs and the number of time domain symbols of CORESET#0 is 2, as shown in Figure 5. Then receiving the PDCCH in step S302 may include: determining the frequency domain position of CORESET#0 based on the SSB and the frequency domain offset of CORESET#0, and determining the time of PDCCH reception based on the number of time domain symbols and time domain position of CORESET#0. domain position, and then receive the PDCCH based on the determined time-frequency domain position of the PDCCH.

In a possible implementation, the value of the time slot offset between the PDCCH and the PDSCH indicated in the second indication information received in step S303 may be a fixed value, or may be configured to be the same as the subcarrier spacing μ of the PDSCH. Other values related to _PDSCH . For example, assuming that the PDCCH and PDSCH slot offset (K ₀ ) is j, and j is a positive integer, then j can take a fixed value (such as 1), or can take other values related to the subcarrier spacing configuration μ of _PDSCH . The corresponding relationship between the time slot offset j and the subcarrier spacing configuration μ _PDSCH is shown in Table 13. Among them, the value of subcarrier spacing configuration μ _PDSCH can indicate the size of different subcarrier spacing, as shown in the values in brackets in Table 13.

0(15KHz)0(15KHz)	11
1(30KHz)1(30KHz)	11
2(60KHz)2(60KHz)	22
3(120KHz)3(120KHz)	33

Optionally, when K ₀ =j (j>0) indicated in the second indication information received in step S303, that is, when the PDCCH corresponding to COSERT#0 and the corresponding PDSCH are not in the same time slot, the DMRS of the PDSCH ( For example, the time domain position of the first DMRS may be as follows: dmrs-TypeA-Position='pos2' corresponds to the index of the starting symbol of the first DMRS being 2, or dmrs-TypeA-Position='pos3' corresponds to the starting symbol of the first DMRS. The index of the initial symbol is 3. Correspondingly, the PDSCH time domain starting symbol and occupied symbol length may be as shown in Table 14 or Table 15 of the PDSCH time domain mapping.

Table 14 Default PDSCH time domain resource allocation for ordinary CP A

Table 15 Default PDSCH time domain resource allocation for extended CP A

Optionally, when K ₀ =j (j>0) indicated in the second indication information received in step S303, the value of the first identifier (“pos2”) may also be 0 or 1. Here, In the application embodiment, refer to Table 14 and Table 15. As mentioned above, when the value of the time slot offset indicated by the second indication information (for example, DCI) is not 0 (for example, K ₀ =j, j>0) When , the value of the first identifier ("pos2") is 0. That is, DMRS is placed at the beginning of the time slot to facilitate early PDSCH channel estimation. At the same time, the number of DMRS symbols can also be increased to ensure the accuracy of channel estimation. Correspondingly, the index (S) of the PDSCH starting symbol can also be fixed to 0. When the PDSCH starting symbol index is 0, see Table 16 and Table 17 for the mapping rules (as shown in the case of S=0).

Figure 6 is a schematic diagram of another example resource allocation of a downlink control channel and a downlink shared channel according to an embodiment of the present application, which is described below in conjunction with the method of the present application.

Optionally, Figure 6 shows an example resource allocation (K ₀ =j=1) when CORESET #0 and PDSCH are not in the same time slot. In the example of Figure 6 , the symbol of PDSCH is 1 RB in the frequency domain. is the unit (optionally, the case of multiple RBs in the frequency domain is the same as the frequency domain distribution of one RB), and the first preset value is 2.

The resource allocation shown in Figure 6 can be obtained according to the method proposed in this application.

First, in step S301, the MIB (first indication information) is received, and the index value of the CORESET#0 mapping in the field pdcch-ConfigSIB1 is obtained. In this example, the index value is 3. It can be known from Table 1 that the number of symbols occupied by the CORESET#0 time domain is 3, and is greater than or equal to the first preset value 2, that is, the received first indication information satisfies the preset condition. It can be known from Table 1 that the frequency domain offset of SSB and CORESET#0 is 0. Then the frequency domain range of CORESET#0 can be determined based on the frequency domain offset of SSB and CORESET#0 and the number of RBs occupied by the frequency domain in Table 1, and then the PDCCH is received in step S302.

Secondly, in step S301, the field dmrs-TypeA-Position can also be obtained from the received MIB (first indication information). In this example, its value is dmrs-TypeA-Position='pos3', and the meaning of 'pos3' is 3. Assuming that the CP type is NCP, the DMRS configuration type is typeA and the DMRS is single symbol, then DCI (second indication information) can also be received in step S304, and the Row index corresponding to the Time domain resource assignment field can be =2 and field dmrs-TypeA-Position='pos3', it can be seen from Table 14 that the starting symbol of PDSCH is S=3, and the symbol duration occupied by PDSCH is L=9. Therefore, the reception of the PDCCH based on the first indication information that satisfies the preset condition in step S302 may include: performing the reception of the PDCCH and the PDSCH associated with the PDCCH based on the first indication information and the second indication information that satisfies the preset condition. take over.

As shown in Figure 6, in the time domain, the first 3 symbols of time slot n are used to receive PDCCH, and the last 9 symbols of time slot n+1 whose time domain offset from time slot n is 1 slot are used to receive PDCCH. For receiving PDSCH, and the DMRS of PDSCH starts from the 4th (ie, index 3) symbol of slot n+1. In this case where CORESET#0 and PDSCH are not in the same time slot, you can also consider extending the number of symbols occupied by CORESET#0 in the time domain (for example, up to no more than 14) to increase the time domain resources occupied by CORESET#0 .

Please refer to Figure 7. Figure 7 is a schematic diagram of another example resource allocation of a downlink control channel and a downlink shared channel according to an embodiment of the present application. It is described as follows in conjunction with the method of the present application.

Optionally, Figure 7 shows an example resource allocation (K ₀ =j=1) when CORESET #0 and PDSCH are not in the same time slot. In the example of Figure 7 , the symbol of PDSCH is 1 RB in the frequency domain. is the unit (optionally, the case of multiple RBs in the frequency domain is the same as the frequency domain distribution of one RB), and the first preset value is 2.

The resource allocation shown in Figure 7 can be obtained according to the method proposed in this application.

First, in step S301, the MIB (first indication information) is received, and the index value of the CORESET#0 mapping in the field pdcch-ConfigSIB1 is obtained. In this example, the index value is 3. It can be known from Table 1 that the number of symbols occupied by the CORESET#0 time domain is 3, and is greater than or equal to the first preset value 2, that is, the received first indication information satisfies the preset condition. Then the frequency domain range of CORESET#0 can be determined based on the frequency domain offset of SSB and CORESET#0 and the number of RBs occupied by the frequency domain in Table 1, and then the PDCCH is received in step S302.

Secondly, in step S301, the field dmrs-TypeA-Position can also be obtained from the received MIB (first indication information). In this example, its value is dmrs-TypeA-Position='pos3', and the meaning of 'pos3' is 3. Assuming that the CP type is NCP, the DMRS configuration type is typeA and the DMRS is single symbol, then DCI (second indication information) can also be received in step S304, and the Row index corresponding to the Time domain resource assignment field can be =2 and field dmrs-TypeA-Position='pos3', it can be seen from Table 16 that the starting symbol of PDSCH is S=0, and the symbol duration occupied by PDSCH is L=9. Therefore, in step S302, receiving the PDCCH according to the first indication information that satisfies the preset condition may include: receiving the PDCCH and the PDSCH associated with the PDCCH according to the first indication information and the second indication information that satisfy the preset condition. .

As shown in Figure 7, in the time domain, the first 3 symbols of time slot n are used to receive PDCCH, and the first 9 symbols of time slot n+1 with a time domain offset of 1 slot from time slot n are used to receive PDCCH. For receiving PDSCH, and the DMRS of PDSCH starts from the 4th (ie, index 3) symbol of slot n+1. In this case, based on the various implementations as mentioned above, other optimizations can also be performed, such as extending the length of L to 14 and pre-configuring the field dmrs-TypeA-Position='pos3' to indicate that the PDSCH carries The starting symbol of the first DMRS has an index of 0, and so on.

It should be noted that, as shown in part of Table 16 and Table 17, when the index (S) of the starting symbol of the PDSCH is 0, the number of DMRS symbols can be further increased.

Referring back to Figure 3, in a possible implementation, the method also includes:

Step S304 (shown by the dotted line in Figure 3): receive third indication information. The third indication information is used to determine the location information of the second demodulation reference signal.

In this embodiment of the present application, the third indication information may be received by the terminal device from the network device, and the third indication information may be Radio Resource Control (Radio Resource Control, RRC) information. As RRC, the second indication information may at least include the configuration corresponding field dmrs-AdditionalPosition for the time domain resource allocation of the remaining DMRS(s) in the PDSCH except the first DMRS.

In this method, the order of the operations of receiving three types of indication information in steps S301, S303 and S304 is not limited to the numerical order of the reference marks, but can be exchanged.

In a possible implementation, the second demodulation reference signal indicated by the third indication information and the first demodulation reference signal indicated by the first indication information are located in the same time slot, and/or the second demodulation reference signal is The starting symbol is after the starting symbol of the first demodulation reference signal.

For example, the DMRS-AdditionalPosition field in the third indication information (such as RRC) may directly indicate the index of the slot symbol of the remaining (multiple) DMRSs (for example, by providing a table/mapping), or may indirectly indicate the remaining (multiple) DMRS slot symbols. Index of the slot symbol of the first DMRS (e.g., by providing a symbol offset from the first DMRS). For example, the symbol index of the first DMRS is L, and this field indicates that the symbol offset of the second DMRS is A, then the symbol index of the second DMRS in the timeslot is L+A, and L+A <14.
