Description

A method and device for obtaining information

This application claims the priority of the Chinese patent application with the application number 202110903586.2 and the application title "A Method and Device for Obtaining Information" submitted to the China Patent Office on August 06, 2021, the entire contents of which are incorporated by reference in this application middle.

technical field

The present application relates to the field of communication technology, and more specifically, to a method and device for acquiring information.

Background technique

In order to improve user experience at the edge of the cell, when there are multiple serving cells for the terminal device, the terminal device can either choose the single transmission and reception point (STRP) mode or the multiple transmission point mode (multiple transmission point). and reception point, MTRP) work. Wherein, the bit length of downlink control information (DCI) configured in the MTRP mode for scheduling data may be longer than that of the DCI used in the STRP mode. For example, in the 3GPP 5G NR Rel-17 version, when the DCI used in MTRP mode needs to indicate two receiving transmission points (transmission and reception point, TRP), compared with the DCI used in STRP mode, DCI needs to add 8 to 14 bits.

At present, when a terminal device switches from MTRP mode to STRP mode, the DCI received by the terminal device may still include information about multiple TRPs, and the terminal device can intercept the second half of the corresponding indication field in the DCI so that the length of the DCI It is the same length as the DCI configured in STRP mode, and then it is interpreted to obtain the information of the TRP. When the terminal device switches from STRP mode to MTRP mode, the DCI received by the terminal device includes information of multiple TRPs, and the terminal device can pad the corresponding indication field in the DCI so that the length of the DCI is the same as that configured in MTRP mode. The length of the DCI is the same, and then it is interpreted to obtain the information of multiple TRPs.

However, when a terminal device switches between MTRP mode and STRP mode, it is not flexible to use zero padding or truncation, and when the DCI includes multiple TRP information and is used to indicate the bit length of each TRP information At the same time, there is a possibility that it cannot be interpreted in the way of zero padding or interception, and there is an urgent need for a method of obtaining information that can flexibly and accurately obtain the information in the control information when switching.

As shown in Fig. 1, a terminal device is located in one or more cells (carriers) and one or more sending and receiving points ( TRP), one or more repeaters (Repeaters) or one or more relays (Relays), there may be one or more cells serving terminal equipment. When there are multiple serving cells for the terminal device, the terminal device can work in a carrier aggregation (carrier aggregation, CA), dual connectivity (dual connectivity, DC) or coordinated multipoint transmission mode.

The terminal device in the embodiment of the present application may refer to a chip, user equipment, access terminal, subscriber unit, subscriber station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device. The terminal device may also be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a Functional handheld devices, computing devices or other processing devices connected to wireless modems, vehicle-mounted devices, wearable devices, terminal devices in 5G networks or terminals in the future evolution of public land mobile network (PLMN) equipment, etc., which are not limited in this embodiment of the present application.

A terminal device may be a device that provides voice/data connectivity to users, for example, a handheld device with a wireless connection function, a vehicle-mounted device, and the like. At present, examples of some terminals are: mobile phones, tablet computers, notebook computers, handheld computers, mobile internet devices (mobile internet device, MID), wearable devices, virtual reality (virtual reality, VR) equipment, augmented reality (augmented reality, AR) equipment, wireless terminals in industrial control, wireless terminals in self driving, wireless terminals in remote surgery, wireless terminals in smart grid, wireless terminals in transportation safety, wireless terminals in smart cities , wireless terminals in smart homes, cellular phones, cordless phones, session initiation protocol (session initiation protocol, SIP) phones, wireless local loop (wireless local loop, WLL) stations, personal digital assistants (personal digital assistant, PDA), Handheld devices with wireless communication functions, computing devices or other processing devices connected to wireless modems, vehicle-mounted devices, wearable devices, terminal devices in future 5G networks or future evolutions of public land mobile network (PLMN) ), etc., which are not limited in this embodiment of the present application.

In addition, in the embodiment of the present application, the access network device is a device in the RAN, or in other words, a RAN node that connects the terminal device to the wireless network. For example, as an example rather than limitation, as access network equipment, it can be listed: Next Generation NodeB (Next Generation NodeB), transmission and reception point (transmission and reception point, TRP), evolved Node B (evolved Node B, eNB) , radio network controller (radio network controller, RNC), node B (Node B, NB), base station controller (base station controller, BSC), base transceiver station (base transceiver station, BTS), home base station (for example, home evolved NodeB, or home Node B, HNB), base band unit (base band unit, BBU), or wireless fidelity (wireless fidelity, Wifi) access point (access point, AP), etc. In a network structure, the access network device may include a centralized unit (centralized unit, CU) node, or a distributed unit (distributed unit, DU) node, or a RAN device including a CU node and a DU node, or a control plane CU node (CU-CP node) and user plane CU node (CU-UP node) and RAN equipment of DU node.

The access network device provides services for the cell, and the terminal device communicates with the access network device through the transmission resources (for example, frequency domain resources, or spectrum resources) used by the cell (carrier), and the cell can be an access network device (For example, a cell corresponding to a base station), the cell may belong to a macro base station, or may belong to a base station corresponding to a small cell, where the small cell may include: a metro cell, a micro cell, or a pico cell (pico cell), femto cell (femto cell), etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

Currently, in order to further enhance the performance of MTRP, Rel-17 defines a physical uplink shared channel (physical uplink shared channel, PUSCH) enhancement scheme. By extending the bit field of the corresponding indication field in the DCI (such as format DCI 0_1, DCI 0_2, DCI 1_1 or DCI 1_2), the DCI can indicate the information of 2 TRPs, thereby supporting the scheme of using two TPRs to transmit data. The indication fields that need to be extended in a DCI supporting two TRPs are listed below:

1. Transmission power control (TPC)

The TPC field is extended from 2 bits to 4 bits. One of the ways to indicate two TRPs is: the TPC field includes two TPC fields, the first TPC field includes the original 2 bits, which are used to indicate the information of a TRP, and the other TPC field includes the newly added 2 bits The bit indicates information of another TRP; another mode is that 4 bits in the TPC field form a TPC field, and the one TPC field indicates information of two TPCs. It should be noted that, RRC may be used to configure a piece of information to indicate whether the TPC field including the newly added 2 bits exists, or to indicate which method is used to indicate the information of two TRPs.

2. Channel sounding reference signal resource indicator (sounding reference signal resource indicator, SRI)

The SRI field may be increased by 1 to 3 bits based on the originally configured number of bits. The SRI field includes two SRI fields, the first SRI field includes the original bits, associated with an SRS resource set, and is used to indicate the relevant information of a TRP, and the other SRI field includes newly added bits, which are different from the other Associated with the SRS resource set of the SRS, indicating the relevant information of another TRP.

It should be noted that the lengths of the two SRI fields may be the same or different, or in other words, the number of newly added bits may be the same as or different from the original number of bits.

For example, when using the codebook method for transmission, if the number of resources in the two SRS resource sets associated with the two SRI domains is the same, then the lengths of the two SRI domains are the same; if the resources in the two SRS resource sets If the number of resources is different, the lengths of the two SRI domains are also different, which are equal to log[N] respectively, where N is the number of resources in the associated SRS resource set.

As an example and not limitation, for STRP mode transmission, the SRI field includes an SRI field, associated with an SRS resource set, and the maximum number of resources in the SRS resource set is 4; for MTRP mode transmission, the SRI field includes two SRI Domains are associated with two SRS resource sets respectively, and the maximum number of resources in each SRS resource set is 4. Tables 1 to 3 respectively show a mapping index list of an SRI domain, wherein the SRS resource set associated with the SRI domain in Table 1 includes 2 resources, and the SRS resource set associated with the SRI domain in Table 2 includes 3 resources. resources, the SRS resource set associated with the SRI domain in Table 3 includes 4 resources.

For another example, when the non-codebook-based transmission is adopted, the number of bits included in the second SRI field may be determined according to the first SRI field. At this time, if the layers of the two TRP transmission information indicated by the definition are the same, the number of bits included in the second SRI field can be determined according to the maximum number of SRI code points of the corresponding layer number indicated by the first SRI field.

As an example and not limitation, for STRP mode transmission, the SRI field includes an SRI field, associated with an SRS resource set, and the maximum number of resources in the SRS resource set is 4; for MTRP mode transmission, the SRI field includes two SRI Domains are associated with two SRS resource sets respectively, and the maximum number of resources in each SRS resource set is 4. Table 4 to Table 7 respectively show the mapping index lists of different maximum layers (layer 1, layer 2, layer 3 and layer 4) in an SRI domain.

3. Transmission precoding matrix indicator (transmitted precoding matrix indicator, TPMI)

The TPMI field may be increased by 1 to 5 bits based on the originally configured number of bits. The TPMI field includes two TPMI fields, the first TPMI field includes the original bits, and the TPMI field usually adopts a codebook-based transmission method, that is, the number of bits included in the second TPMI field can be determined according to the first TPMI field , that is, the number of newly added bits. For example, the number of bits included in the second TPMI field may be determined according to the maximum number of TPMI code points in the layer indicated by the first TPMI field. Specifically, Table 8 shows a mapping index list of a TPMI domain, where the three parameters fullyAndPartialAndNonCoherent, partialAndNonCoherent, and nonCoherent can be configured through RRC, that is to say, as an example, the terminal device can determine according to the configuration of the three parameters Which column of the three-column mapping index in Table 8 is used to interpret the TPMI domain.

Table 8:

4. Phase tracking reference signal-demodulation reference signal (phase tracking reference signals-demodulation reference signal, PTRS-DMRS) relationship

When the maxRank of the PTRS-DMRS field is equal to 2, no new bits are added, and the original bits are reused to indicate the relevant information of the two TRPs, for example, the MSB and LSB are used to indicate the relevant information of the two TRPs respectively; when the maxRank is greater than 2, you can add a PTRS-DMRS field, for example, the original bits form a PTRS-DMRS field, and add 2 bits to form another PTRS-DMRS field, and the two PTRS-DMRS fields indicate the correlation between the two TRPs respectively. information. At present, relevant protocols also define a related mapping index list for the PTRS-DMRS domain, which will not be repeated here for simplicity.

5. Dynamic switching between STRP and MTRP (dynamic switching between STRP and MTRP)

This field includes 2 bits, and is used to indicate switching between MTRP operation and STRP operation in MTRP mode. Table 9 shows the definition of this field.

Table 9:

According to the current protocols TS 38.212 and TS 38.213, the DCI used to activate the bandwidth part (BWP) includes one or more indication fields. When different BWPs configure different TRP transmission modes, for example, BWP#1 configures STRP mode for transmission, and BWP#2 configures MTRP mode for transmission. From the above, it can be seen that DCI#1 in BWP#1 and DCI in BWP#2 The lengths of one or more indication fields present in DCI#2 and the corresponding fields will be different.

When switching from BWP#1 to BWP#2, STRP mode switches to MTRP mode:

The terminal device needs to obtain two TRP information from the received DCI#1, and the terminal device can pad the indication field shorter than DCI#2 in DCI#1 with zeros in front, so that the corresponding indication field in DCI#1 The length is consistent with that in DCI#2, and then the terminal device interprets it to obtain the information of the two TRPs.

For clarity, take the SRI field in DCI as an example. Assume that the length of SRI#1 in DCI#1 is 3 bits, and the length of SRI#2 in DCI#2 is 6 bits. If the terminal device receives the SRI #1 is "011", then it will be interpreted after zero padding to "000011".

When switching from BWP#2 to BWP#1, MTRP mode switches to STRP mode:

The DCI#2 received by the terminal device may still include two TRP information, and the terminal device only needs one TRP information, and the terminal device can intercept the indication field longer than DCI#2 in DCI#1, so that DCI# The length of the corresponding indication field in 1 is consistent with that in DCI#2, and then the terminal device interprets it to obtain the information of a TRP.

For clarity, take the SRI field in DCI as an example. Assume that the length of SRI#1 in DCI#1 is 6 bits, and the length of SRI#2 in DCI#2 is 3 bits. If the terminal device receives the SRI #1 is "011101", then intercept the last three digits and change it to "101" for interpretation.

However, this way of obtaining information when switching modes is not flexible enough, and is prone to errors, for example, if always prepending 0, an indication error may occur. In addition, when a certain indication field in the DCI includes two fields respectively indicating two TRP information, and the number of bits included in the two fields is different, zero padding or truncation may not be able to obtain the correct information. For clarity, the following uses the SRI indicator field as an example. Assume that BWP#1 to which DCI#1 belongs is configured with STRP mode. SRI#1 in DCI#1 is an indicator field, and SRI#1 includes 3 bits; assume that DCI#2 belongs BWP#2 of BWP#2 configures MTRP mode, SRI#2 in DCI#2 includes SRI field #21 and SRI field #22, and SRI field #21 and SRI field #22 are used to indicate the information of TRP#1 and TRP#2 respectively, the The SRI field #21 includes 3 bits, and the SRI field #22 includes 2 bits.

If you switch from BWP#1 to BWP#2, switch from STRP mode to MTRP mode, and the terminal device receives SRI#1, the terminal device cannot determine the number of zeros that need to be added before SRI#1, or it cannot know that it needs to be in front of SRI#1 The number of bits included in SRI#2 is the same as the number of bits included in SRI#2 by adding two 0s, so that the terminal device cannot obtain correct information of two TRPs from DCI#1.

If switching from BWP#2 to BWP#1, the MTRP mode switches to STRP mode, the terminal device receives SRI#2, and SRI#2 includes 3-bit SRI field #21 and 2-bit SRI field #22, the terminal device The number of bits to be truncated cannot be judged, so the terminal equipment cannot obtain correct required TRP information from DCI#2.

Therefore, there is an urgent need for a method for obtaining information, which can flexibly and accurately obtain the information required in the control information during switching.

FIG. 2 shows a schematic flow chart of a method 200 for acquiring information proposed in this application.

The method is applied in a communication system supporting the first configuration and the second configuration. When the system switches between the first configuration and the second configuration, the method 200 includes steps S210 to S240.

Optionally, the first configuration is a configuration of a single receiving transmission point mode, and the second configuration is a configuration of a multi-receiving transmission point mode, and/or,

The first configuration is a configuration in a multi-reception transmission point mode, and the second configuration is a configuration in a single reception transmission point mode, and/or,

The first configuration and the second configuration are configurations of the same or different frequency bandwidth parts respectively, and/or,

The first configuration and the second configuration are respectively the same or different carrier configurations, and/or,

The first configuration and the second configuration are configurations of the same or different cells respectively, and/or,

The first configuration and the second configuration are configurations of the same or different time domain formats respectively.

For example, the switch between the first configuration and the second configuration may be a switch between STRP mode and MTRP mode, or a switch between different BWPs. The BWP configured with STRP mode and the BWP configured with MTRP mode Handover can also be a handover between different carriers, a handover between a carrier configured with STRP mode and a carrier configured with MTRP mode, or a handover between different cells, between a cell configured with STRP mode and a carrier configured with MTRP mode The handover between cells may also be a handover between a BWP and a cell, a handover between a BWP and a carrier, or a handover between a cell and a carrier.

The first configuration or the second configuration can be understood as having a BWP, carrier or cell, or as a configuration of the BWP, carrier or cell, or a configuration under the BWP, carrier or cell. It should be noted that the first configuration and the second configuration are different configurations and have different modes and or formats for interpreting information. When the system switches between the first configuration and the second configuration, the terminal device may need to change the How to interpret the information received.

S210. The terminal device receives first control information under the first configuration.

For example, the terminal device receives the first control information under the first configuration from the access network device #1, and correspondingly, the access network device #1 sends the first control information under the first configuration to the terminal device.

It should be noted that the configuration method of the first control information adopts the first configuration method, but the information carried in the first control information is information about the second configuration, that is, the first control information received by the terminal device information, the first control information may not be interpreted in the manner of the first configuration, but the first control information may be interpreted in other ways to obtain the required information.

That is to say, the size or format of the control information in different modes is different. For example, the number of bits included in some indication fields in the DCI in STRP mode is less than the number of bits included in the indication field in MTRP mode. . When the control information in the first configuration schedules the channel in the second configuration, the terminal device needs to convert the control information in the first configuration into the second configuration, and then interpret and obtain the required second control information.

Optionally, the terminal device receives switching information, where the switching information is used to indicate switching from the first configuration to the second configuration.

S220. The terminal device determines transmission of the first channel under the second configuration according to the first control information.

It should be noted that the first channel may be PUSCH, PDSCH, PUCCH, or PDCCH, etc., and the first channel may also be understood as data or signaling that needs to be transmitted, which is not limited in this application.

For clarity, the following is an example of switching between STRP mode and MTRP mode. The embodiment of the present application is used to switch between different cells and different carriers in a similar manner. For simplicity, here No longer.

As an example and not a limitation, assume that the first configuration corresponds to access network device #1, and the second configuration corresponds to access network device #2 and access network device #3, wherein, access network device #1 and access network device # Network device #2 may be the same access network device.

In the scenario of switching between STRP mode and MTRP mode, the first control information may be carried in DCI, including at least one of the following information: single-reception transmission point and multi-reception transmission point conversion, transmission power control TPC, sounding Reference signal resource indication SRI, transmission precoding matrix indication TPMI, and phase tracking reference signal-demodulation reference signal PTRS-DMRS.

In other scenarios, the first control information may also be RRC information, MAC-CE information, DCI information, or one or more information elements (information element, IE) carried in RRC information, or MAC-CE Control element (control element, CE), or one or more information fields (information field), request field (request field), indicator field (indicator field) of DCI, etc.

The terminal device may adopt the following seven methods for determining the transmission of the first channel under the second configuration according to the first control information, and the seven methods will be introduced respectively below.

First, take switching from STRP to MTRP as an example.

The length of the first control information is greater than the length of the second control information.

Or, it can also be said that the length of the control information defined in the first configuration is greater than the length of the control information defined in the second configuration.

In the following modes 1 to 3, the method 200 may further include step S230.

S230. The terminal device determines second control information according to the first control information.

The second control information includes a first bit field and at least one second bit field, the first control information includes a third bit field, and the first bit field is the same as the third bit field.

As an example and not a limitation, the fact that the first bit field is the same as the third bit resource can be understood as the length of the first bit finger and the second bit field are the same, and/or the bit values are the same, and/or the association of the indicated content or The mapping relationship is the same.

The second bit field can be one or more, for example, the second bit field is an SRI domain, and the first or more SRI domains can respectively correspond to one or more SRS resource sets (SRS resource set), for clarity, A second bit field is used for introduction below.

Method 1:

The second bit field is the same bit field as the first bit field.

It should be noted that the first bit field and the second bit field are the same bit field, which means that the bits included in the first bit field and the second bit field are the same, but the information interpreted by the first bit field and the second bit field It may not be used. For example, refer to FIG. 3. FIG. 3 shows a schematic structural diagram of switching the field included in the first control information as the SRI field. When the field included in the first control information is the SRI field, the first bit field and The second bit field is associated with different SRS resource sets. If the first control information is 0111, the second control information consists of the first bit field and the second bit field, which is 01110111.

Method 2:

The length of the second bit field is the first length, and the first length is determined according to the first bit field.

The second bit field is a bit field of the first length obtained by intercepting from the most significant bit of the first bit field,

Alternatively, the second bit field is a bit field of the first length obtained by truncating from the least significant bit of the first bit field, where the first length is determined according to the first bit field.

As an example and not a limitation, take the first control information including the SRI domain as an example, assuming that the configuration of the SRI domain is based on non-codebook transmission, the maximum number of layers is 2, and one SRS recourse set includes 4 resources, and its mapping index table Columns 5 and 6 shown in Table 5 (see Table 10):

Table 10:

比特字段bit field	对应的取值corresponding value	SRI(s)，N _SRS＝4 SRI(s), N _SRS =4
00000000	00	00
00010001	11	11
00100010	22	22

00110011	33	33
01000100	44	0,10,1
01010101	55	0,20,2
01100110	66	0,30,3
01110111	77	1,21,2
10001000	88	1,31,3
10011001	99	2,32,3
1010-11111010-1111	10-1510-15	reservedreserved

Optionally, the first length is the maximum code point of the first set described by the first bit field, and the first set is a bit field including the same number of layers.

For example, in Table 10, the layer number corresponding to the bit field with a corresponding value from 0 to 3 is 1, and the corresponding layer number to a bit field with a corresponding value from 4 to 9 is 2, then the first set may include The set of bit fields 0000 to 0011 may also be a set including bit fields 0100 to 1001.

For another example, taking the first control information including the TPMI field as an example, assuming that the configuration mode of the TPMI field is based on codebook transmission, the mapping index table adopts the fifth column and the sixth column shown in Table 8. The corresponding bit field with a value of 0 to 3 corresponds to a layer number of 1, and the corresponding bit field with a value of 4 to 9 corresponds to a layer number of 2. Similarly, the first set may include bit fields 0000 to 0011 A set may also be a set including bit fields 0100 to 1001.

It should be noted that the above is only an example of the SRI field and the TPMI field. The first control information may also include other fields, and the method for determining the first bit field and the second bit field is similar. Let me repeat.

The first length is the maximum code point of the first set described by the first bit field. It can be understood that the terminal device determines the first length corresponding to the first set according to the number of bit fields included in the first set.

For example, if the first set includes 4 bit fields of bit fields 0000 to 0011, the 4 bit fields require at least 2 bits for indexing, and at this time, the first length is 2; if the first set includes bit fields 0100 to 1001 There are 6 bit fields in total, and the 6 bit fields require at least 3 bits for indexing. In this case, the first length is 3.

For example, referring to FIG. 4, if the second bit field is a bit field of the first length obtained by intercepting from the most significant bit of the first bit field, assuming that the first bit field is 0111, the first bit field belongs to The first set, the first length corresponding to the first set is 3, in this case, the second bit field is 011.

For example, referring to FIG. 5, if the second bit field is a bit field of the first length obtained by intercepting from the least significant bit of the first bit field, it is assumed that the first bit field is 0111, and the first bit field belongs to the first set, and the first length corresponding to the first set is 3, in this case, the second bit field is 111.

Method 3:

The first bit field belongs to the second set, and the second bit field is one of the plurality of bit fields in the second set.

For example, the second set may include bit fields whose corresponding values are within a preset range.

The description about the second set is similar to the description of the first set, and for the sake of brevity, details are omitted here.

As an example but not a limitation, the first control information includes the SRI field as an example, assuming that the second set is a corresponding bit field with a value of 4 to 9, that is, a bit field 0100 to 1001, then the second bit field can be a bit field Any one of fields 0100 to 1001.

In a possible implementation manner, the second bit field is a bit field corresponding to a maximum value in the second set.

For example, the first bit field is 1000, the second bit field belongs to the second set, and the second set is a corresponding bit field with a value of 4 to 9. At this time, the second bit field is a corresponding value of 9 bit field 1001.

In another possible implementation manner, the second bit field is a corresponding minimum value bit field in the second set.

For example, the first bit field is 1000, the second bit field belongs to the second set, and the second set is a corresponding bit field with a value of 4 to 9. At this time, the second bit field is a corresponding value of 4 Bit field 0100.

Determining the second control information based on the first control information in modes 1 to 3 can be understood as expanding on the basis of the bit fields included in the original first control information, and the second control information will still include the original bit fields .

In mode 4 to mode 7, the terminal device may directly determine the transmission of the first channel under the second configuration according to the first control information, and mode 4 to mode 7 will be introduced respectively below.

Method 4:

Determining the transmission of the first channel under the second configuration according to the first control information includes:

Perform joint decoding on the first control information to obtain transmission of the first channel under the second configuration.

The first control information is obtained through joint coding.

As an example but not a limitation, the first control information is an SRI field, which is used to indicate two access network devices in MTRP mode, and the first control information is associated with the two access network devices Indicates that the domains are jointly encoded. Assuming that the SRI field is configured in such a way that each SRS resource set includes 4 resources, you can refer to Table 11 to obtain the joint code point according to the values of the SRI fields corresponding to the two access network devices, that is, the value corresponding to the first control information value or code point.

Table 11:

Optionally, the index mapping list of joint code points can be configured through RRC, for example, 0-63 joint code points and corresponding value combinations corresponding to the two SRI fields can be configured through RRC, and then the MAC-CE can be used to determine the corresponding value combination with the SRI field The code points corresponding to the bit length, for example, there may be 16 joint code points corresponding to the first control information including 4 bits at most.

In a possible implementation manner, the access network device may perform mapping in an equidistant coding manner according to the effective number of configured joint coding points and the bit length of the SRI field.

For example, the following formula can be used for mapping.

x+y=M

Among them, N is the valid number of configured joint code points, and M is the number of code points that can be indicated by the SRI field. Through listing, x steps can be obtained as

The joint code point of , y steps are

joint code point.

For example, referring to Table 10, assuming that the effective number of configured joint code points is 64, and the bit length of the SRI field is 4, that is, the number of code points that the SRI field can indicate is 16, then it can be known that

x=6, y=10, then the values corresponding to the 16 joint coding points are: 0, 2, 4, 6, 8, 10, 13, 16, 19, 22, 25, 28, 31, 34, 37 , 40.

After receiving the first control information obtained through joint coding, the terminal device can determine the transmission of the first channel under the second configuration by decoding.

It should be noted that the above is only an example of the SRI field, and the first control information may also include other fields, which are determined in a similar manner, and are not repeated here for simplicity.

In the following manners 5 to 7, the first control information may include a STRP and MTRP dynamic switching indication field, which is used to indicate that switching occurs between MTRP operation and STRP operation in MTRP mode.

As an example rather than a limitation, the SRI domain is used as an example for clarity.

Way 5:

The terminal device parses the first control information, and uses the first control information to instruct one of the access network devices corresponding to the second configuration to send, for example, one of the first control information and the MTRP configuration The first SRS resource set (corresponding to access network device #2) is associated.

If the STRP operation is performed on the first channel in the MTRP mode, the terminal device may perform transmission on the first channel with the access network device #2 according to the first SRS resource set indicated by the first control information.

If the second device performs MTRP operation in MTRP mode, the terminal device can transmit the first channel with the access network device #2 according to the first SRS resource set indicated by the first control information, and according to the last transmission configuration or preset The configured parameters are transmitted with the access network device #3 on the first channel.

Optionally, the first SRS resource set is an SRS resource set with the smallest index among multiple SRS resource sets in the MTRP mode.

For example, referring to FIG. 6 , in the MTRP mode, the SRS resource set 1 corresponding to the first access network device #1 and the SRS resource set 2 corresponding to the second access network device #2 and the corresponding channel information (for example, as shown in FIG. 6 PUSCH #1 and PUSCH #2 shown), the terminal device can associate with the first SRS resource set (for example, SRS resource set 1 in FIG. 6 ) according to the first control information, and the first SRS resource set is associated with the first The association of control information can adopt static configuration, dynamic configuration or protocol constraints. In this case, other indication information, such as corresponding information of PUSCH#1, can be obtained from the first control information.

Method 6:

The first control information is used to indicate the monitoring information of the third control information under the second configuration, and the third control information is used to determine the transmission of the first channel under the second configuration, and the monitoring information includes the following information At least one item: monitoring window bias, monitoring period.

For example, referring to FIG. 7 , the terminal device parses the first control information to obtain monitoring information of the third control information in MTRP mode. Therefore, the terminal device can monitor according to the monitoring information, so as to obtain the channel information corresponding to the first access network device #2 and the second access network device #3 in MTRP mode (for example, PUSCH #1 and PUSCH #1 shown in FIG. 7 #2), so as to determine the transmission of the first channel under the second configuration.

Way 7:

The terminal device determines that switching between MTRP mode and STRP mode occurs according to the switching information. The parameters in MTRP mode are pre-configured or default configured parameters. Transmission of the first channel under the second configuration.

The foregoing manners 1 to 7 are used as examples to introduce how the terminal device determines the transmission of the first channel under the second configuration according to the first control information.

Take the example of switching from MTRP to STRP.

The length of the first control information is longer than the length of the second control information.

The terminal device may intercept the first control information to obtain the second control information, so as to determine transmission of the first channel under the second configuration according to the second control information.

S240. Transmit the first channel between the terminal device and the access network device.

The information of the access network device may be determined according to the first control information in step S220.

The transmission of the first channel between the terminal device and the access network device includes the following two situations:

Case 1:

Assuming that the access network devices under the second configuration include access network device #2 and access network device #3, the transmission of the first channel between the terminal device and the access network device includes:

The terminal device sends the first channel to the access network device #2 and the access network device #3, and correspondingly, the access network device #1 and the access network device #2 receive the first channel from the terminal device; or,

The terminal device receives the first channel from the access network device #2 and the access network device #3, and correspondingly, the access network device #2 and the access network device #3 send the first channel to the terminal device.

Case 2:

Use methods 5 to 7 to determine the transmission of the first channel. The transmission of the first channel is STRP operation in MTRP mode. Assume that the STRP operation corresponds to access network device #1, and the transmission between the terminal device and the access network device First channel, including:

The terminal device sends the first channel to the access network device #2, and correspondingly, the access network device #2 receives the first channel from the terminal device; or,

The terminal device receives the first channel from the access network device #2, and correspondingly, the access network device #2 sends the first channel to the terminal device.

It should be noted that the above is an example of performing STRP operation in MTRP mode and corresponding to access network device #2. The embodiment of the present application can also correspond to other access network devices in MTRP mode, and this application does not specifically limit it. .

One way to restrict switching is described below.

It should be noted that the first configuration, the second configuration, and the switching between the first configuration and the second configuration are similar to those described in the method 200 , and for simplicity, details are not repeated here.

The terminal device is a terminal device with only the first configuration capability, or the terminal device is a terminal device with only the second configuration capability, or the terminal device has the first configuration and the second configuration, and does not support switching between the first configuration and the second configuration capabilities of terminal equipment.

For example, the terminal device is a terminal device only capable of STRP mode, or the terminal device is a terminal device only capable of MTRP mode, or the terminal device is a terminal device capable of switching between MTRP mode and STRP mode but not supporting MTRP mode and STRP mode equipment.

The following describes the configuration methods of the two restriction switches:

Take MTRP mode and STRP mode as examples.

Method A:

Configure MTRP mode and STRP mode as cell-level configurations, or different BWPs in a cell.

For example, parameters can be configured at the cell level (such as the RRC parameter ServingCellConfig), explicitly add MTRP mode and STRP mode selection or enable switch, and indicate the supported transmission mode through static, semi-static or dynamic.

Optionally, the number of SRS resource sets configured for transmission by the access network device is the same.

Method B:

When different BWPs and different TRP operation modes (STRP operation or MTRP operation) are configured, it is stipulated that this BWP switching is prohibited; the STRP mode or MTRP mode switching can be realized through RRC reconfiguration.

Therefore, in this application, the supported transmission mode can be indicated statically, semi-statically or dynamically to limit the occurrence of handover, thereby avoiding the ambiguity problem that is likely to occur during handover.

Wherein, when the apparatus 1000 is used to execute the method in FIG. 2 , the transceiver unit 1200 can be used to receive the first control information under the first configuration, and also be used to transmit the first channel; the processing unit 1100 can be used to transmit the first channel according to the The first control information determines the transmission of the first channel in the second configuration. It should be understood that the specific process for each unit to perform the above corresponding steps has been described in detail in the above method embodiments, and for the sake of brevity, details are not repeated here.

It should also be understood that when the device 1000 is a chip or chip system configured in a terminal device, the transceiver unit 1200 in the device 1000 can be realized through an input/output interface, a circuit, etc., and the processing unit 1100 in the device 1000 can be realized through the Implementations such as processors, microprocessors, or integrated circuits integrated on a chip or system-on-a-chip.

It should be understood that the apparatus 1000 may correspond to the access network device in the method according to the embodiment of the present application, and the apparatus 1000 may include a unit for performing the method performed by the access network device in FIG. 2 .
