Description

Method and device for acquiring information

Technical Field

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

Background

In order to improve the cell edge user experience, when there are multiple serving cells for the terminal device, the terminal device may select a Single Transmission and Reception Point (STRP) mode, or may adopt a Multiple Transmission and Reception Point (MTRP) mode to work. A 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 release, when DCI used in MTRP mode needs to indicate 2 reception transmission points (TRPs), the DCI needs to be newly increased by 8 to 14 bits compared to DCI used in STRP mode.

At present, when a terminal device switches from an MTRP mode to an STRP mode, DCI received by the terminal device may still include information of a plurality of TRPs, and the terminal device may intercept a second half of a corresponding indication field in the DCI, so that the length of the DCI is the same as the length of DCI configured in the STRP mode, and then perform an interpretation to obtain the information of the TRPs. When the terminal device switches from the STRP mode to the MTRP mode, the DCI received by the terminal device includes information of a plurality of TRPs, and the terminal device may perform zero padding on a corresponding indication field in the DCI, so that the length of the DCI is the same as the length of the DCI configured in the MTRP mode, and then perform interpretation to obtain information of the plurality of TRPs.

However, the terminal device switches between the MTRP mode and the STRP mode, and the method of zero padding or truncation does not have flexibility, and when the DCI includes a plurality of pieces of TRP information and the bit length of the information indicating each TRP is different, there is a possibility that the method of zero padding or truncation cannot be interpreted.

When there are a plurality of serving cells for a terminal device, the terminal device may operate according to Carrier Aggregation (CA), dual Connectivity (DC), or coordinated multipoint transmission.

A terminal device in the embodiments of the present application may refer to a chip, a user equipment, an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent, or a user equipment. 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 handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a 5G network or a terminal device in a Public Land Mobile Network (PLMN) for future evolution, and the like, which are not limited in this embodiment.

The terminal device may be a device providing voice/data connectivity to a user, e.g. a handheld device, a vehicle mounted device, etc. with wireless connection capability. Currently, some examples of terminals are: a mobile phone, a tablet computer, a notebook computer, a palm computer, a Mobile Internet Device (MID), a wearable device, a Virtual Reality (VR) device, an Augmented Reality (AR) device, a wireless terminal in industrial control, a wireless terminal in self driving, a wireless terminal in tele-surgery, a wireless terminal in smart grid, a wireless terminal in transportation security, a wireless terminal in smart city, a wireless terminal in smart home, a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a future Public Land Mobile Network (PLMN) device in 5G, or a mobile network (PLMN) device, and the like.

In addition, in this embodiment, the access network device is a device in the RAN, or in other words, a RAN node that accesses the terminal device to the wireless network. For example, by way of example and not limitation, as access network devices, mention may be made of: next Generation Node B (Next Generation NodeB), transmission and Reception Point (TRP), evolved Node B (eNB), radio Network Controller (RNC), node B (NB), base Station Controller (BSC), base Transceiver Station (BTS), home base station (e.g., home evolved Node B, or home Node B, HNB), base Band Unit (BBU), or wireless fidelity (Wifi) Access Point (AP), etc. In one network configuration, an access network device may include a Centralized Unit (CU) node, or a 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 a user plane CU node (CU-UP node) and a RAN device of a DU node.

The access network device provides service for a cell, and a terminal device communicates with the access network device through a transmission resource (e.g., a frequency domain resource, or a spectrum resource) used by the cell (carrier), where the cell may be a cell corresponding to the access network device (e.g., a base station), and the cell may belong to a macro base station or a base station corresponding to a small cell (small cell), where the small cell may include: urban cell (metro cell), micro cell (microcell), pico cell (pico cell), femto cell (femto cell), etc., and these small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-rate data transmission service.

Currently, in order to further enhance the performance of MTRP, rel-17 defines a scheme for Physical Uplink Shared Channel (PUSCH) enhancement. A scheme of transmitting data using two TPRs may be supported by extending a bit field of a corresponding indication field in DCI (e.g., format DCI 0_1, DCI 0_2, DCI 1_1, or DCI 1 _2) so that the DCI can indicate information of 2 TRPs. The indication fields that need to be extended in DCI supporting two TRPs are listed below:

1. transmission Power Control (TPC)

The TPC field is extended from 2 bits to 4 bits. One way to indicate two TRPs is: the TPC field comprises two TPC domains, wherein the first TPC domain comprises original 2 bits and is used for indicating information of one TRP, and the other TPC domain comprises newly added 2 bits and is used for indicating information of the other TRP; another way is that 4 bits in the TPC field constitute one TPC field, which indicates information of two TPCs. It should be noted that, an information may be configured by the RRC to indicate whether a TPC field including the additional 2 bits exists, or to indicate in which manner to indicate information of the two TRPs.

2. Channel sounding reference Signal Resource Indicator (SRI)

The SRI field may be increased by 1 to 3 bits based on the number of bits originally configured. The SRI field comprises two SRI fields, a first SRI field comprising original bits associated with one SRS resource set for indicating related information of one TRP, and a second SRI field comprising additional bits associated with a different SRS resource set for indicating related information of another TRP.

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

For example, when the codebook mode is adopted for transmission, if the number of resources in two SRS resource sets associated with two SRI domains is the same, the lengths of the two SRI domains are the same; if the number of resources in two SRS resource sets is not the same, the length of the two SRI domains is also different, equal to log [ N ], respectively, where N is the number of resources in the SRS resource set associated therewith.

By way of example and not limitation, for STRP mode transmissions, the SRI field includes one SRI field associated with one SRS resource set with a maximum number of resources of 4; for MTRP mode transmission, the SRI field includes two SRI domains, respectively associated with two SRS resource sets, and the maximum number of resources in each SRS resource set is 4. Tables 1 to 3 respectively show mapping index lists of an SRI domain, where SRS resource set associated with the SRI domain in table 1 includes 2 resources, SRS resource set associated with the SRI domain in table 2 includes 3 resources, and SRS resource set associated with the SRI domain in table 3 includes 4 resources.

table 2:

Bit field mapped to index	SRI(s),N _SRS ＝3
		0	0
1	1
		2	2
3	Reserved

table 3:

for another example, when the transmission is performed in a non-codebook based manner, the number of bits included in the second SRI field may be determined according to the first SRI field. At this time, if the number of layers of the two TRP transmission information indicated by the definition is the same, the number of bits included in the second SRI field may be determined according to the maximum number of SRI coding points corresponding to the number of layers indicated by the first SRI field.

By way of example and not limitation, for STRP mode transmissions, the SRI field includes one SRI field associated with one SRS resource set with a maximum number of resources of 4; for MTRP mode transmission, the SRI field includes two SRI domains, respectively associated with two SRS resource sets, and the maximum number of resources in each SRS resource set is 4. Tables 4 to 7 show mapping index lists of different maximum layer numbers (1 layer, 2 layers, 3 layers and 4 layers, respectively) of one SRI field, respectively.

3. transmission Precoding Matrix Indicator (TPMI)

The TPMI field may be increased by 1 to 5 bits based on the number of bits originally configured. The TPMI field includes two TPMI fields, the first TPMI field includes original bits, the TPMI field usually adopts a codebook-based transmission method, i.e. the number of bits included in the second TPMI field, i.e. the number of newly added bits, can be determined according to the first TPMI field, for example, the number of bits included in the second TPMI field can be determined according to the maximum number of TPMI coding points in the layer indicated by the first TPMI field. Specifically, table 8 shows a mapping index list of a TPMI domain, where three parameters, fullyandpartialandncouherent, partialandncouherent, and nonCoherent, may be configured by RRC, that is, as an example, a terminal device may determine which column of three columns of mapping indexes in table 8 is used to interpret the TPMI domain according to the configuration of the three parameters.

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

When maxRank of the PTRS-DMRS field is equal to 2, no new bit is added, and the original bit is multiplexed to indicate the related information of the two TRPs, for example, MSB and LSB are used for indicating the related information of the two TRPs respectively; when the maxRank is larger than 2, a PTRS-DMRS domain may be newly added, for example, an original bit forms one PTRS-DMRS domain, 2 bits are newly added to form another PTRS-DMRS domain, and the two PTRS-DMRS domains respectively indicate related information of two TRPs. At present, related mapping index lists are also defined for the PTRS-DMRS domain by related protocols, and are not described herein for simplicity.

Dynamic switching of STRP and MTRP (dynamic switching between STRP and MTRP)

This field includes 2 bits for indicating that a switch occurs between MTRP operation and STRP operation in MTRP mode, and table 9 shows the definition of this field.

Table 9:

according to the current protocols TS 38.212 and TS 38.213, one or more indication fields are included in the DCI for active partial Bandwidth (BWP). 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, it can be seen from the above that the length of the indication field or fields and corresponding fields in DCI #1 in BWP #1 and DCI #2 in BWP #2 are different.

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

the terminal device needs to obtain information of two TRPs from the received DCI #1, the terminal device may perform preceding zero padding on the indication field shorter than the DCI #2 in the DCI #1 so that the length of the corresponding indication field in the DCI #1 is consistent with that in the DCI #2, and then the terminal device performs interpretation to obtain information of two TRPs.

For clarity, the SRI field in the DCI is taken as an example, assuming 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 SRI #1 received by the terminal device is "011", it is read after being zero-padded 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 information of two TRPs, the terminal device only needs information of one TRP, and the terminal device may perform post-interception on an indication field longer than the DCI #2 in the DCI #1, so that the length of the corresponding indication field in the DCI #1 is consistent with that in the DCI #2, and then the terminal device performs interpretation to obtain information of one TRP.

For clarity, the SRI field in the DCI is taken as an example, assuming that the length of SRI #1 in DCI #1 is 6 bits, the length of SRI #2 in DCI #2 is 3 bits, and if SRI #1 received by the terminal device is "011101", the last three bits are intercepted to be "101", and then the terminal device performs interpretation.

However, the manner of acquiring information during mode switching is not flexible enough, and is prone to error, for example, an indication error may occur if 0 is always prepended. Moreover, when two fields included in a certain indication field in the DCI respectively indicate information of two TRPs and the number of bits included in the two fields is different, the zero padding or the truncation may not be able to obtain correct information. For clarity, the SRI indication field is illustrated below, and it is assumed that the STRP mode is configured for BWP #1 to which DCI #1 belongs, SRI #1 in DCI #1 is one indication field, and SRI #1 includes 3 bits; assuming that BWP #2 to which DCI #2 belongs configures an MTRP mode, SRI #2 in DCI #2 includes SRI field #21 and SRI field #22, SRI field #21 and SRI field #22 are used to indicate information of TRP #1 and TRP #2, respectively, SRI field #21 includes 3 bits, and SRI field #22 includes 2 bits.

If the BWP #1 is switched to the BWP #2 and the strp mode is switched to the MTRP mode, the terminal device receives the SRI #1, and the terminal device cannot determine the number of bits that need to be padded with zeros before the SRI #1, or cannot know that 20 bits need to be padded before the SRI #1 to be the same as the number of bits included in the SRI #2, so that the terminal device cannot obtain information of two correct TRPs from the DCI # 1.

If switching from BWP #2 to BWP #1 and switching from mtrp mode to STRP mode, the terminal device receives SRI #2, where SRI #2 includes 3 bits of SRI field #21 and 2 bits of SRI field #22, and the terminal device cannot determine the number of bits that need to be intercepted, so that the terminal device cannot obtain correct required TRP information from DCI # 2.

Therefore, a method for acquiring information is needed to flexibly and accurately acquire the information required in the control information during handover.

Fig. 2 shows a schematic flow chart of a method 200 for obtaining information proposed by the present application.

The method is applied to a communication system supporting a first configuration and a second configuration, and when the system is switched 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 reception transmission point mode, the second configuration is a configuration of a multiple reception transmission point mode, and/or,

the first configuration is a configuration in a multiple receive transmission point mode, the second configuration is a configuration in a single receive transmission point mode, and/or,

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

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

For example, the switching between the first configuration and the second configuration may be switching between an STRP mode and an MTRP mode, switching between different BWPs, switching between a BWP configuring an STRP mode and a BWP configuring an MTRP mode, switching between different carriers, switching between a carrier configuring an STRP mode and a carrier configuring an MTRP mode, switching between different cells, switching between a cell configuring an STRP mode and a cell configuring an MTRP mode, switching between a BWP and a cell, switching between a BWP and a carrier, or switching between a cell and a carrier.

The first configuration or the second configuration may be understood as having a BWP, carrier or cell, or may be understood 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 of the interpretation information, and when the system switches between the first configuration and the second configuration, the terminal device may need to change the interpretation manner of the received information.

S210, the terminal equipment receives first control information under first configuration.

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

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

That is, 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 the STRP mode is less than the number of bits included in the indication fields in the MTRP mode. When the control information under the first configuration schedules a channel under the second configuration, the terminal device needs to convert the control information under the first configuration into the second configuration, and then reads the second configuration to obtain the required second control information.

Optionally, the terminal device receives handover information indicating a handover from the first configuration to the second configuration.

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

The first channel may be a PUSCH, a PDSCH, a PUCCH, a PDCCH, or the like, and the first channel may also be understood as data or signaling that needs to be transmitted, which is not limited in the present application.

For clarity, in the following, a scenario of switching between the STRP mode and the MTRP mode is taken as an example, and the manner for switching between different cells and switching between different carriers in the embodiments of the present application is similar, and for simplicity, details are not described herein again.

By way of example and not limitation, assume that access network device #1 corresponds to the first configuration, access network device #2 corresponds to the second configuration, and access network device #3, where access network device #1 and access network device #2 may be the same access network device.

In a scenario of switching between the STRP mode and the MTRP mode, the first control information may be carried in DCI, and includes at least one of the following information: the method comprises the steps of single-receiving transmission point and multi-receiving 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, in other words, one or more Information Elements (IEs) carried in the RRC information, or a MAC-CE Control Element (CE), or one or more information fields (information fields), request fields (request fields), indication fields (indicator fields) of the DCI.

The terminal device determines transmission of the first channel in the second configuration according to the first control information in the following 7 ways, and the 7 ways are described below respectively.

First, an example will be given in which the STRP is switched to the MTRP.

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

Alternatively, the length of the control information defined in the first configuration may be larger 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.

And S230, the terminal equipment determines second control information according to the first control information.

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

By way of example and not limitation, the first bit field being identical to the third bit resource may be understood as the first bit end and the second bit field being of the same length and/or having the same bit value and/or having the same association or mapping of the indicated content.

The second bit field may be one or more, for example, the second bit field is an SRI field, and the first one or more SRI fields may respectively correspond to one or more SRS resource sets (SRS resource sets), and for clarity, the second bit field is described below.

Mode 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 bits included in the first bit field and the second bit field are the same, but the information explained by the first bit field and the second bit field may not be used, for example, referring to fig. 3, fig. 3 shows a schematic structure diagram of switching when the field included in the first control information is an SRI field, the first bit field and the second bit field are associated with different SRS resource sets, and if the first control information is 0111, the second control information is composed of the first bit field and the second bit field, which is 01110111.

Mode 2:

the length of the second bit field is a first length, which is determined according to the first bit field.

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

or, the second bit field is a bit field of the first length obtained by cutting from the least significant bit of the first bit field, wherein the first length is determined according to the first bit field.

By way of example and not limitation, the first control information includes an SRI field for example, and it is assumed that the SRI field is configured in a manner based on non-codebook transmission, the maximum number of layers is 2,1 SRS receive set including 4 resources, and the mapping index table thereof is the 5th column and the 6 th column shown in table 5 (see table 10):

table 10:

bit field	Corresponding value of	SRI(s)，N _SRS ＝4
			0000	0	0
0001	1	1
			0010	2	2
0011	3	3
			0100	4	0,1
0101	5	0,2
			0110	6	0,3
0111	7	1,2
			1000	8	1,3
1001	9	2,3
			1010-1111	10-15	reserved

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

For example, in table 10, if the number of layers corresponding to the bit fields with values of 0 to 3 is 1, and the number of layers corresponding to the bit fields with values of 4 to 9 is 2, the first set may be a set including bit fields 0000 to 0011, or a set including bit fields 0100 to 1001.

For another example, the first control information includes the TPMI field, and assuming that the TPMI field is configured based on codebook transmission, the mapping index table thereof adopts the 5th column and the 6 th column shown in table 8. The number of layers corresponding to the corresponding bit fields with values from 0 to 3 is 1, and the number of layers corresponding to the corresponding bit fields with values from 4 to 9 is 2, and similarly, the first set may be a set including bit fields 0000 to 0011, or a set including bit fields 0100 to 1001.

It should be noted that, the SRI field and the TPMI field are only used for example, and the first control information may further include other fields, and the manner of determining the first bit field and the second bit field is similar to that of the first control information, and for simplicity, details are not described herein again.

The first length is a maximum coding point of the first set of the first bit field, and may be understood as that the terminal device determines, according to the number of bit fields included in the first set, the first length corresponding to the first set.

For example, if the first set includes 4 bit fields of 0000 to 0011, the 4 bit fields need at least 2 bits for indexing, and the first length is 2; if the first set includes 6 bit fields of bit fields 0100 to 1001, the 6 bit fields require at least 3 bits for indexing, and 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 cutting from the most significant bit of the first bit field, assuming that the first bit field is 0111, the first bit field belongs to a first set, and the first length of 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 cutting from the least significant bit of the first bit field, it is assumed that the first bit field is 0111, the first bit field belongs to a first set, the first set corresponds to a first length of 3, and in this case, the second bit field is 111.

Mode 3:

the first bit field belongs to a second set, the second bit field being one of a plurality of bit fields in the second set.

For example, the second set may be a field of bits that includes a corresponding value within a preset range.

The description of the second set is similar to that of the first set and will not be repeated here for simplicity.

By way of example and not limitation, still taking the example that the first control information includes an SRI field, assuming that the second set is a corresponding bit field with a value of 4 to 9, i.e., bit fields 0100 to 1001, then the second bit field may be any one of bit fields 0100 to 1001.

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

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

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

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

In the manner 1 to the manner 3, determining the second control information according to the first control information may be understood as extending based on a bit field included in the original first control information, and the second control information may still include the original bit field.

In the methods 4 to 7, the terminal device may determine transmission of the first channel in the second configuration directly according to the first control information, and the methods 4 to 7 are described below.

Mode 4:

determining transmission of the first channel in the second configuration according to the first control information, comprising:

jointly decoding the first control information to obtain a transmission of the first channel in a second configuration.

The first control information is obtained by joint encoding.

By way of example and not limitation, the first control information is one SRI field, the one SRI field is used for indicating 2 access network devices in the MTRP mode, and the first control information is obtained by performing joint coding on indication fields associated with the 2 access network devices. Assuming that the SRI field is configured in a manner that each SRS resource set includes 4 resources, the joint coding point, that is, the value or the coding point corresponding to the first control information, may be obtained according to the values of the SRI domains corresponding to the two access network devices by referring to table 11.

Table 11:

optionally, an index mapping list of the joint coding points may be configured by the RRC, for example, 0 to 63 joint coding points and a value combination corresponding to two corresponding SRI domains are configured by the RRC, and then a coding point corresponding to the bit length of the SRI field is determined by the MAC-CE, for example, at most 16 joint coding points corresponding to the first control information including 4 bits may be provided.

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

For example, the following formula may be employed for mapping.

x+y＝M

Wherein, N is the effective number of the configured joint coding points, M is the number of the coding points which can be indicated by the SRI field, and x stepping can be obtained by going to the market

Y steps are->

The joint coding point of (1).

For example, referring to table 10, assuming that the valid number of configured joint encoding points is 64, the bit length of the SRI field is 4, i.e. the number of encoding points that can be indicated by the SRI field is 16, it can be known that

x =6, y =10, then the corresponding values of 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 by the joint coding, the terminal device may determine the transmission of the first channel in the second configuration by decoding.

It should be noted that, the above is only exemplified by the SRI field, and the first control information may further include other fields, and the determination manner thereof is similar, and for simplicity, the details are not described herein again.

In the following modes 5 to 7, the first control information may include STRP and MTRP dynamic transition indication fields for indicating that a handover occurs between MTRP operation and STRP operation in the MTRP mode.

By way of example, and not limitation, for clarity, SRI domains are exemplified.

Mode 5:

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

If the first channel performs the STRP operation in the MTRP mode, the terminal device may perform transmission of 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 the MTRP mode, the terminal device may perform transmission of the first channel with the access network device #2 according to the first SRS resource set indicated by the first control information, and perform transmission of the first channel with the access network device #3 according to the parameter configured or preconfigured in the last transmission.

Optionally, the first SRS resource set is a set of SRS resources with a smallest index among a plurality of sets of SRS resources in the MTRP mode.

For example, referring to fig. 6, including SRS resource set 1 corresponding to the first access network device #1 and SRS resource set 2 corresponding to the second access network device #2 and information of corresponding channels (e.g. PUSCH #1 and PUSCH #2 shown in fig. 6) in the mtrp mode, the terminal device may associate with the first SRS resource set (e.g. SRS resource set 1 in fig. 6) according to the first control information, and the association of the first SRS resource set with the first control information may adopt a static configuration, a dynamic configuration, or a protocol constraint. In this case, other indication information, for example, corresponding information of PUSCH #1, may be obtained from the first control information.

Mode 6:

the first control information is used for indicating monitoring information of third control information in the second configuration, the third control information is used for determining transmission of the first channel in the second configuration, and the monitoring information comprises at least one of the following information: monitoring window offset and 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 the MTRP mode. Thus, the terminal device may perform monitoring according to the monitoring information to acquire information (e.g., PUSCH #1 and PUSCH #2 shown in fig. 7) of channels corresponding to the first access network device #2 and the second access network device #3 in the MTRP mode, thereby determining transmission of the first channel in the second configuration.

Mode 7:

and the terminal equipment determines that the MTRP mode and the STRP mode are switched according to the switching information, the parameter in the MTRP mode is a parameter configured in advance or configured in default, and the terminal equipment determines the transmission of the first channel in the second configuration according to the parameter configured in advance, configured in advance or configured in default.

Mode 1 to mode 7 above have described, as an example, that the terminal device determines transmission of the first channel in the second configuration according to the first control information.

Examples are given if 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 second control information, thereby determining transmission of the first channel under the second configuration according to the second control information.

And S240, transmitting a first channel between the terminal equipment and the access network equipment.

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

The first channel transmission between the terminal equipment and the access network equipment comprises the following two conditions:

case 1:

assuming that the access network device in the second configuration includes an access network device #2 and an access network device #3, the transmitting a first channel between the terminal device and the access network device includes:

the terminal equipment sends the first channel to the access network equipment #2 and the access network equipment #3, and correspondingly, the access network equipment #1 and the access network equipment #2 receive the first channel from the terminal equipment; alternatively, the first and second electrodes may be,

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

Case 2:

determining transmission of a first channel by using modes 5 to 7, where the transmission of the first channel is performing an STRP operation in an MTRP mode, and assuming that the STRP operation corresponds to an access network device #1, the transmitting of the first channel between the terminal device and the access network device includes:

the terminal equipment sends the first channel to the access network equipment #2, and correspondingly, the access network equipment #2 receives the first channel from the terminal equipment; alternatively, the first and second electrodes may be,

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

It should be noted that, the above is exemplified by performing STRP operation in the MTRP mode, and corresponds to the access network device #2, but the embodiment of the present application may also correspond to other access network devices in the MTRP mode, and the present application is not limited to this.

Therefore, in the application, the first control information received by the terminal device is the first configuration, and the terminal device can interpret the first control information to determine what way the first channel under the second configuration is transmitted, so that the information in the control information can be flexibly and accurately acquired during configuration switching.

A method of restricting handover is introduced 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 are not described herein again for simplicity.

The terminal device is a terminal device only having a first configuration capability, or the terminal device is a terminal device only having a second configuration capability, or the terminal device is a terminal device having the first configuration and the second configuration and not supporting the capability of switching the first configuration and the second configuration.

For example, the terminal device is a terminal device having only an STRP mode capability, or the terminal device is a terminal device having only an MTRP mode capability, or the terminal device is a terminal device having an MTRP mode and an STRP mode and not supporting a capability of switching between the MTRP mode and the STRP mode.

Two configurations of the restricted handover are described below:

MTRP mode and STRP mode are exemplified.

Mode A:

the MTRP mode and the STRP mode are configured to be configured at a cell level, or different BWPs in a cell.

For example, parameters (e.g., RRC parameter ServingCellConfig), explicit addition of MTRP mode and STRP mode selection or enabling switches may be configured at the cell level to indicate supported transmission modes via static, semi-static, or dynamic.

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

Mode B:

provision is made to prohibit such BWP switching when different TRP operation modes (STRP operation or MTRP operation) for different BWPs are configured; the switching between the STRP mode and the MTRP mode can be realized through RRC reconfiguration.

Thus, in the present application, the occurrence of a handover can be defined by the transmission mode supported by a static, semi-static or dynamic indication, thereby avoiding the ambiguity problem that easily occurs when switching.

Fig. 8 is a schematic block diagram of an apparatus provided by an embodiment of the present application. As shown in fig. 8, the apparatus 1000 may include a processing unit 1100 and a transceiving unit 1200.

It should also be understood that, when the apparatus 1000 is a chip or a chip system configured in a terminal device, the transceiver unit 1200 in the apparatus 1000 may be implemented by an input/output interface, a circuit, etc., and the processing unit 1100 in the apparatus 1000 may be implemented by a processor, a microprocessor, an integrated circuit, etc., integrated on the chip or the chip system.
