Description

Configuration method, terminal and network side equipment for time division multiplexing carrier aggregation

Technical Field

Background

In the related art, a network side device configures a time division multiplexing (Time Division Duplex, TDD) carrier aggregation (Carrier Aggregation, CA) including a plurality of serving cells for a terminal, and the terminal performs half duplex operation in the TDD CA configured by the network side device. A half-duplex terminal can only receive downlink or uplink transmission on a certain time or orthogonal frequency division multiplexing (Orthogonal frequency division multiplex, OFDM) symbol, i.e. does not support simultaneous uplink and downlink transmission on the same OFDM symbol. The terminal needs to determine the reference cell according to a certain rule, and then determine the final direction according to the uplink or downlink direction on the reference cell.

Fig. 1 shows a block diagram of a wireless communication system to which embodiments of the present application are applicable. The wireless communication system includes a terminal 11 and a network device 12. The terminal 11 may be a mobile phone, a tablet (Tablet Personal Computer), a Laptop (Laptop Computer) or a terminal-side Device called a notebook, a personal digital assistant (Personal Digital Assistant, PDA), a palm top, a netbook, an ultra-mobile personal Computer (ultra-mobile personal Computer, UMPC), a mobile internet appliance (Mobile Internet Device, MID), an augmented reality (augmented reality, AR)/Virtual Reality (VR) Device, a robot, a Wearable Device (weather Device), a vehicle-mounted Device (VUE), a pedestrian terminal (PUE), a smart home (home Device with a wireless communication function, such as a refrigerator, a television, a washing machine, or a furniture), a game machine, a personal Computer (personal Computer, PC), a teller machine, or a self-service machine, and the Wearable Device includes: intelligent wrist-watch, intelligent bracelet, intelligent earphone, intelligent glasses, intelligent ornament (intelligent bracelet, intelligent ring, intelligent necklace, intelligent anklet, intelligent foot chain etc.), intelligent wrist strap, intelligent clothing etc.. Note that, the specific type of the terminal 11 is not limited in the embodiment of the present application.

In the new air interface, the configuration of the uplink and downlink timeslots depends on TDD uplink and downlink configuration common signaling (TDD-UL-DL-configuration common), TDD uplink and downlink configuration specific signaling (TDD-UL-DL-configuration decoded) and a timeslot format indicator (Slot Format Indicator, SFI), where the SFI is timeslot configuration signaling carried by downlink control information (Downlink Control Information, DCI) format 2_0, as shown in fig. 2. Wherein,

tdd-UL-DL-configuration command is configured at a cell level, typically configured by system information of the cell, such as system information block (System Information Block, SIB) 1;

the tdd-UL-DL-configuration defined is a UE-specific configuration that can only modify Flexible compliance (Flexible Symbol) in the tdd-UL-DL-configuration command configuration, but cannot change downlink symbols (DL, D) indicated by the tdd-UL-DL-configuration command to uplink symbols (UL, U), and the uplink symbols to downlink symbols.

Flexible Symbol (F) is a Symbol obtained by removing configured uplink and downlink slots (slots) or the number of uplink and downlink symbols in a period configured by tdd-UL-DL-configuration command and/or tdd-UL-DL-configuration.

The SFI indicates uplink and downlink slot format change through DCI.

In the related art, if one UE is configured with a plurality of serving cells and a directional collision process-r 16 is configured for a group of serving cells among the configured plurality of serving cells (i.e., directional collisionhandling-r16= 'enabled'), and indicates that half duplex half-duplex tdd-CA-samscs-r 16 capability is supported, DCI format 2_0 is not configured to be detected on any one serving cell, the UE determines a reference cell for one symbol among the plurality of serving cells, the reference cell being an active cell configured with a minimum cell index on the symbol as follows:

semi-static SFI downstream (Semi-static SFI D) or Semi-static SFI upstream (Semi-static SFI U), i.e., downstream configured by tdd-UL-DL-configuration Common or tdd-UL-DL-configuration Deguided, or upstream;

a radio resource control (Radio Resource Control, RRC) D corresponds to a downlink transmission configured higher on a Semi-static SFI F, such as a physical downlink control channel (Physical downlink control channel, PDCCH), or a physical downlink shared channel (Physical downlink shared channel, PDSCH), such as a Semi-persistent scheduling (Semi-Persistent Scheduling, SPS) PDSCH, or a downlink Reference Signal, such as channel state information (Channel state information, CSI) -Reference Signal (RS), tracking Reference Signal (Tracking Reference Signal, TRS), positioning Reference Signal (Positioning Reference Signal, PRS), or the like.

RRC U corresponds to uplink transmission configured at a higher layer on the Semi-static SFI F, such as a sounding reference signal (Sounding Reference Signal, SRS), or a physical uplink control channel (Physical Uplink Control Channel, PUCCH), or a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH), or a physical random access channel (Physical Random Access Channel, PRACH).

Dynamic D (Dynamic D) and Dynamic U (Dynamic U) correspond to symbols scheduled as D and U by DCI formats other than DCI format2_0 at Semi-static SFI F.

That is, the half-duplex CAUE determines a reference cell, i.e., a cell having the lowest cell ID among a plurality of serving cells in a frequency band or a frequency band combination of which a direction is determined by semi-static SFI D/U or RRC D/U, for each symbol; and the reference cell may be updated symbol by symbol.

In the related art, the uplink and downlink collision handling of the half duplex TDD CA terminal is shown in table 1, in which UE behavior is classified as (i) applicable to intra-band CA only (ii) applicable to inter-band CA only (iii) applicable to both intra-band and inter-band CA.

Table 1.

It can be seen that the half duplex terminal configured with TDD CA, especially in-band TDD CA, cannot be configured with conflicting D and U on different carriers (or serving cells), for example, with the configuration shown in fig. 3, errors will occur, and the semi-static SFI D or the semi-static SFI U of different carriers on each symbol cannot collide in the transmission or reception direction in time, thereby causing limitation on configuration/scheduling of the network side device and affecting coexistence with other terminals.

The configuration scheme of time division multiplexing carrier aggregation provided by the embodiments of the present application is described in detail below with reference to the accompanying drawings by some embodiments and application scenarios thereof.

Fig. 4 shows a schematic flow chart of a method for configuring time division multiplexing carrier aggregation in an embodiment of the present application, and the method 400 may be performed by a terminal. In other words, the method may be performed by software or hardware installed on the terminal. As shown in fig. 4, the method may include the following steps.

S410, the terminal sends first capability information to the network side equipment, wherein the first capability information indicates that the terminal has the following capabilities: half duplex operation is supported in TDD CA with serving cells of non-identical SCS.

That is, in the embodiment of the present application, the terminal supports half duplex operation in TDD CA and the serving cell (serving cell) in the CA may have a different SCS. By reporting the first capability information to the network side device, the network side device can learn that the terminal has the capability of supporting half-duplex operation in the TDD CA of the serving cell with the different SCS, so that the network side device can configure the serving cell with the different SCS when configuring the TDD CA for the terminal.

In one possible implementation, the half-duplex operation includes: directional conflict handling (directional collision handling between reference and other cell (s)) between a reference cell and other cells, wherein the other cells are serving cells in TDD CA other than the reference cell. That is, the terminal has directional conflict handling capability between the reference cell and other cells. So that the network side device can know that the terminal supports the directional conflict processing between the reference cell and other cells in the TDD CA with the non-identical SCS.

In one possible implementation, the first capability information is further used to indicate at least one of:

(1) And SCS combinations supported by the terminal, wherein the SCS combinations comprise a plurality of different SCSs. For example, the first capability information may indicate that SCS combinations supported by the terminal include: {15KHz,30KHz }, {15KHz,30KHz,60KHz }, {60KHz,120KHz }, {30KHz,120KHz }, {15KHz,30KHz,120KHz }, {15KHz,30KHz,60KHz,120KHz }. Through the possible implementation manner, the network side equipment can acquire SCS combinations supported by the terminal, so that the network side equipment can refer to the combinations when configuring the TDD CA for the terminal, and configure a service cell for the terminal.

(2) The SCS of the reference cell supported by the terminal is the largest SCS of the SCS combinations supported by the terminal. That is, in this possible implementation, the first capability information indicates that the SCS of the reference cell supported by the terminal is the larger SCS of the SCS combination. For example, the SCS of the reference cell that the terminal reports to support is the larger SCS, and when the terminal supports {15KHz,30KHz }, the SCS of the reference cell should be 30KHz. Through the possible implementation manner, the network side equipment can acquire the reference cell possibly selected by the terminal, so that the reference cell can be referred to, and uplink and downlink time slots of the serving cell in the TDD CA can be configured for the terminal.

(3) The SCS of the reference cell supported by the terminal is the smallest SCS of the SCS combination supported by the terminal. That is, in this possible implementation, the first capability information indicates that the SCS of the reference cell supported by the terminal is the smaller SCS of the SCS combination. For example, the SCS of the reference cell that the terminal reports to support is a smaller SCS, and when the terminal supports {15KHz,30KHz }, the SCS of the reference cell should be 15KHz. Through the possible implementation manner, the network side equipment can acquire the reference cell possibly selected by the terminal, so that the reference cell can be referred to, and uplink and downlink time slots of the serving cell in the TDD CA can be configured for the terminal.

In this possible implementation, the terminal does not expect that the downlink time unit configured on the serving cell with the first SCS in the target TDD CA overlaps with the uplink time unit configured on the serving cell with the second SCS partially or entirely, wherein the first SCS is different from the second SCS. In embodiments of the present application, a time unit may include one or more slots and/or one or more OFDM symbols. That is, in this possible implementation, the terminal does not expect a partial overlap of DL or UL slots/symbols (symbols) configured on the serving cell with the larger SCS and UL or DL slots/symbols of any other serving cell with the smaller SCS.

And S412, the terminal receives configuration information sent by the network side equipment, wherein the configuration information is used for configuring a target TDD CA, and SCSs of a plurality of service cells configured in the target TDD CA are not identical.

In the embodiment of the present application, the network side device may perform reasonable configuration according to the capability of the terminal reporting, for example, configure TDD CA with different SCS according to the combination of the supported different SCS reported by the terminal.

In this embodiment of the present application, since the terminal does not expect that the downlink time unit configured on the serving cell with the first SCS in the target TDD CA overlaps with the uplink time unit configured on the serving cell with the second SCS partially or completely, the configuration of the network side device cannot cause the DL or UL slot/symbol (symbol) configured on the serving cell with the larger SCS to overlap with the UL or DL slot/symbol of any other serving cell with the smaller SCS partially.

Table 2 shows a case where the terminal expects a configuration and the network side device is correctly configured, and table 3 shows a case where the terminal does not expect a configuration and the network side device is incorrectly configured.

Table 2.

Table 3.

According to the technical scheme provided by the embodiment of the application, the terminal reports the capability information to the network side equipment, the terminal is indicated to support half-duplex operation in the TDD CA of the service cell with the SCS which is not identical, and the network side equipment configures the target TDD CA for the terminal based on the capability information, wherein SCSs of a plurality of service cells configured in the target TDD CA are not identical, so that the terminal can perform half-duplex operation in the TDD CA of the service cell with the SCS which is not identical, and the flexibility of the TDD CA configuration is improved.

In a possible implementation manner of the embodiment of the present application, after S412, the terminal may further determine a reference cell corresponding to the first time from the configured plurality of serving cells.

Alternatively, the reference cells corresponding to the first time may be one or more, for example, the reference cells corresponding to the first time include a plurality of reference cells, and different reference cells apply frequency bands that are not identical or completely different, for example, different reference cells apply different frequency bands, and one frequency band corresponds to one reference cell.

For example, the reference cell may be a reference cell configured by the network, and the network may configure one reference cell; or the network may configure N (N > 1) reference cells that are applied in different time periods, where the time periods of the different reference cells are not exactly the same or are completely different, e.g., only one reference cell in each time period, the reference cells applied in different time periods are not the same; or the N reference cells are applied in different frequency bands, the frequency bands applied by the different reference cells are not identical or completely different, for example, only one reference cell in each frequency band is different from one reference cell to another. For example, the terminal configures 4 CCs (cc#0, cc#1, cc#2, cc#3), where ccs#0 and #1 belong to band a, ccs#2 and #3 belong to band B, and each band corresponds to one reference cell, and for band a, the reference cell network of the UE is configured as cc#0. For band B, the reference cell network of the UE is configured as CC #2.

For another example, when the network side device includes 5 CCs { (cc#0, scs=30 KHz), (cc#1, scs=15 KHz), (cc#2, scs=15 KHz), (cc#3, scs=120 KHz), (cc#4, scs=120 KHz)) in the TDD CA configured for the terminal, the reference cell is an active cell having the smallest SCS and the cell index is smallest, where cc#0, #1, #2 belongs to band a, and ccs#3 and #4 belong to band B, and if the reference cell is 1, the reference cell is cc#1; if each band corresponds to one reference cell, the number of reference cells is 2, band A is CC#1, and band B is CC#3.

Optionally, the terminal determines a reference cell corresponding to the first time from the configured plurality of serving cells, including at least one of the following (1) to (5).

(1) And determining a reference cell corresponding to the first time according to the reference cell configured by the network side equipment.

In this possible implementation manner, the reference cell may be configured by the network side device, and the terminal may determine, according to the configuration of the network side device, the reference cell corresponding to the first time.

For example, the network side device may configure a reference cell, and the terminal determines that the reference cell corresponding to the first time is the reference cell configured by the network side device. For example, when configuring a plurality of serving cells in the TDD CA, the network side device may configure one of the serving cells as a reference cell, and the terminal may determine, according to the configuration of the network side device, the reference cell corresponding to the first time.

For another example, the network side device may also configure N (N > 1) reference cells, where time periods applied by different reference cells of the N reference cells configured by the network side device may not be identical or completely different, for example, different reference cells of the N reference cells configured by the network side device may be applied to different time periods, only one reference cell in each time period, and the terminal may obtain, according to the configuration of the network side device, a reference cell configured by the network side device and corresponding to the first time.

For another example, the reference cells corresponding to the first time are plural, and the frequency bands corresponding to different reference cells in the plural reference cells corresponding to the first time are not identical or completely different, for example, the frequency bands corresponding to different reference cells in the plural reference cells corresponding to the first time are different. That is, the terminal determines a reference cell corresponding to the first time for each frequency band. The N reference cells configured by the network side equipment can also be applied to different frequency bands, and only one reference cell exists in each frequency band. For example, the network side device configures 4 CCs (cc#0, cc#1, cc#2, cc#3) for the terminal, where ccs#0 and#1 belong to band a, and ccs#2 and#3 belong to band B, and for band a, the reference cell configured by the network side device for the UE is cc#0. For band B, the reference cell configured by the network side device for the UE is cc#2.

(2) The reference cell corresponding to the first time is determined to be an active cell of the plurality of serving cells having a minimum component carrier (Component carrier, CC) index.

(3) And determining the reference cell corresponding to the first time as an active cell with the smallest SCS in the plurality of service cells.

Alternatively, if there are a plurality of active cells having the smallest SCS among the plurality of serving cells and only one reference cell corresponding to the first time, the active cell having the smallest SCS may be selected as the reference cell.

(4) And determining the reference cell corresponding to the first time as an active cell with the largest SCS in the plurality of service cells.

Alternatively, if there are a plurality of active cells having the largest SCS among the plurality of serving cells and only one reference cell corresponding to the first time, the active cell having the largest SCS with the smallest CC index may be selected as the reference cell.

(5) The reference cell corresponding to the first time is determined to be an active cell configured as a target symbol type at the first time.

Wherein the target symbol type comprises at least one of:

downlink or uplink configured by TDD uplink downlink configuration common signaling (TDD-UL-DL-configuration common);

downlink or uplink configured by TDD uplink downlink configuration specific signaling (TDD-UL-DL-configuration specific);

downlink transmission configured by higher layer signaling, e.g., PDCCH, PDSCH, or CSI-RS;

Uplink transmissions configured by higher layer signaling, e.g., SRS, PUCCH, PUSCH or PRACH.

Alternatively, in a case where the number of active cells configured as the target symbol type at the first time is greater than the number of reference cells corresponding to the first time, the reference cell corresponding to the first time may be an active cell having the smallest or largest SCS among the active cells in (5), or the reference cell corresponding to the first time may be an active cell having the smallest CC index among the active cells in (5), or the reference cell corresponding to the first time may be an active cell in (5), the smallest or largest SCS and the smallest CC index.

In an embodiment of the present application, the first time may include at least one of:

(1) A first time of network side equipment configuration; that is, the first time is a time period configured by the network side, which may be determined by the network side device according to the actual application.

(2) The first time the protocol agrees with.

The first time agreed by the protocol may be a fixed value, i.e. independent of SCS of the serving cell, e.g. fixed to 0.5ms or 1 OFDM symbol. Alternatively, the first time agreed by the protocol is related to the SCS of the serving or reference cell, that is, the protocol agrees that the serving or reference cell of a different SCS corresponds to a different first time. For example, the first time the protocol agrees with may be as shown in Table 4.

Table 4.

SCS	First time of
		15KHz	X0 slots, x0=1
30KHz	X1 slots, x1=2
		60KHz	X2 slots, x2=8
120KHz	X3 slots, x3=16

(3) A first time determined according to the capabilities of the terminal. That is, the first time depends on the capability of the terminal to report. For example, the terminal may update the reference cell every X symbols or every Y slots or every Z milliseconds, and the first time may be X symbols, Y slots or Z milliseconds. With this possible implementation, the terminal can determine the reference cells for X symbols, Y slots, or Z milliseconds at a time, according to its capabilities, without determining the reference cells for each OFDM symbol, reducing the complexity of determining the reference cells.

(4) And determining a time period from the reference cell corresponding to the first time to the determined change of the reference cell, wherein the determined change of the reference cell comprises one of the following steps: the determined reference cell is deactivated, the determined reference cell enters a dormant state, and the determined configuration of the reference cell is updated. For example, the terminal determines that the reference cell is cc#0 at slot n, and that cc#0 is deactivated or undergoes a sleep state or configuration update at slot m, e.g., the reference cell is updated by cell 1 to cell 2; or the configuration on the reference cell is updated, such as the reference cell or the cell 1, but some configurations of the cell 1 are updated, such as the current active BWP of the cell 1 is updated from bwp#0 to bwp#1, the uplink and downlink transmission parameters of the cell 1 are updated, etc., the first time is the period from time slot n to time slot m, i.e., (m-n) time slots, that is, from the determination that a certain serving cell is the reference cell to the deactivation or dormancy or update of the serving cell, and the terminal takes the serving cell as the reference cell. With this possible implementation, the terminal can determine the reference cell for a longer time at a time without determining the reference cell for each OFDM symbol, reducing the complexity of determining the reference cell.

In one possible implementation, the terminal does not desire to update the reference cell within a second time, the second time having a time length greater than or equal to the first time. That is, in this possible implementation, once the terminal determines the reference cell, the terminal does not desire to update the reference cell at a second time, where the length of the second time > = the length of the first time. By the possible implementation manner, the terminal does not expect to update the reference cell in the second time, so that the problem of complexity increase of the terminal caused by frequent change of the reference cell can be avoided, and the complexity of updating the reference cell by the terminal is reduced.

For example, a half duplex terminal can only receive downlink or uplink transmission at a certain time or OFDM symbol, i.e. it does not support simultaneous uplink and downlink transmission on the same symbol. The terminal needs to determine the reference cell according to a certain rule, and then determine the final direction according to the uplink or downlink direction on the reference cell. In the related art, however, the reference cell may be changed per symbol, thereby causing a certain complexity to the terminal.

In one possible implementation, the second time includes at least one of:

(1) And a second time configured by the network side equipment. That is, the second time is a time period configured by the network side, which may be determined by the network side device according to the actual application.

(2) The second time the protocol agrees with.

The second time agreed by the protocol may be a fixed value, i.e. independent of SCS of the serving cell, e.g. fixed to 0.5ms or 1 OFDM symbol. Alternatively, the second time agreed by the protocol is related to the SCS of the serving or reference cell, that is, the protocol agrees to the second, different time corresponding to the serving or reference cell of the different SCS. For example, the second time agreed by the protocol may be as shown in Table 5.

Table 5.

SCS	Second time of
		15KHz	X0 slots, x0=1
30KHz	X1 slots, x1=2
		60KHz	X2 slots, x2=8
120KHz	X3 slots, x3=16

(3) And a second time determined according to the capabilities of the terminal. That is, the second time may depend on the terminal's reporting capability, e.g., the terminal may update the reference cell every X symbols or every Y slots or every Z milliseconds, and may be X symbols or Y slots or Z milliseconds.

(4) And determining a time period from the reference cell corresponding to the first time to the determined change of the reference cell, wherein the determined change of the reference cell comprises one of the following steps: the determined reference cell is deactivated, the determined reference cell enters a dormant state, and the determined configuration of the reference cell is updated.

For example, the TDD CA configured by the network side device for the terminal includes two cells, cc#0 and cc#3, and the first time is 1 OFDM symbol, and the second time is 1 slot, i.e., 14 OFDM symbols. The terminal determines a reference cell for each OFDM symbol according to the manner. When the terminal determines that the reference cell is cc#0 on OFDM symbol #i, the terminal does not expect the symbol type of the network configuration so that the reference cell is updated to cc#1 on OFDM symbol #j, where (j-i) <14.

After the network side device configures the TDD CA for the terminal, symbol types of each serving cell configured by the network side device may collide, and in the embodiment of the present application, a scheme for processing collisions in different directions in half duplex operation of the TDD CA is also provided.

In one possible implementation manner, after the terminal determines the reference cell corresponding to the first time from the configured plurality of serving cells, the method may further include: and under the condition that the type of the TDD uplink and downlink configuration public signaling configuration target symbol of the first cell is a first type, and the type of the TDD uplink and downlink configuration public signaling configuration target symbol of the second cell is a second type, the terminal determines that the target symbol is a flexible symbol, or the terminal ignores the TDD uplink and downlink configuration public signaling, wherein the first type is different from the second type, and the first cell and the second cell are different service cells in a plurality of service cells. Alternatively, the first cell may comprise a reference cell on the target symbol.

For example, on the same symbol, the symbol is configured as D or U by referring to the tdd-UL-DL-configuration command of the cell or the cell 1, and configured as U or D by the tdd-UL-DL-configuration command of the other cell or the cell 2, the terminal considers the symbol as a flexible symbol, i.e. the terminal needs to receive other signaling to confirm whether the direction of the symbol is D, U or F; or the terminal ignores the tdd-UL-DL-configurationcommand signaling. The other cells are serving cells except the reference cell in the plurality of serving cells of the network side equipment configured with the TDD CA, and the cell 1 and the cell 2 are different serving cells in the plurality of serving cells of the network side equipment configured with the TDD CA.

In another possible implementation manner, in one possible implementation manner, after the terminal determines a reference cell corresponding to the first time from the configured plurality of serving cells, the method may further include: and under the condition that the type of the TDD uplink and downlink configuration common signaling configuration target symbol of the first cell is a first type, and the type of the TDD uplink and downlink configuration specific signaling configuration target symbol of the second cell is a second type, the terminal determines that the type of the target symbol is the second type. Alternatively, the first cell may comprise a reference cell on the target symbol.

For example, on the same symbol, the symbol is configured as D or U by referring to the tdd-UL-DL-configuration command of the cell or the cell 1, and configured as U or D by the tdd-UL-DL-configuration commands of the other cell or the cell 2, the terminal considers that the direction of the symbol is U or D, i.e., the terminal is based on the tdd-UL-DL-configuration command, and allows the tdd-UL-DL-configuration command to rewrite the direction of the tdd-UL-DL-configuration command. The other cells are serving cells except the reference cell in the plurality of serving cells of the network side equipment configured with the TDD CA, and the cell 1 and the cell 2 are different serving cells in the plurality of serving cells of the network side equipment configured with the TDD CA.

In another possible implementation manner, after the terminal determines the reference cell corresponding to the first time from the configured plurality of serving cells, the method may further include: and under the condition that the type of the TDD uplink and downlink configuration specific signaling configuration target symbol of the first cell is a first type and the type of the TDD uplink and downlink configuration specific signaling configuration target symbol of the second cell is a second type, the terminal determines that the type of the target symbol is the first type or the terminal determines that the configuration of the target symbol is wrong.

For example, on the same symbol, the reference cell or the tdd-UL-DL-configuration-configured of cell 1 configures the symbol as D or U, and the other cells or the tdd-UL-DL-configuration-configured of cell 2 configures the symbol as U or D, the terminal considers the direction of the symbol as D or U, i.e., the terminal is configured with the tdd-UL-DL-configuration-configured on the reference cell as standard; or this is a network erroneous configuration.

In another possible implementation manner, after the terminal determines the reference cell corresponding to the first time from the configured plurality of serving cells, the method may further include: when the type of the target symbol configured by the TDD uplink and downlink configuration common signaling or the TDD uplink and downlink configuration specific signaling of the first cell is downlink, or the terminal is configured by the high-layer signaling to receive downlink transmission on the target symbol, and the first dynamic signaling of the second cell indicates that uplink transmission is scheduled on the target symbol or the first dynamic signaling indicates that the type of the target symbol is uplink, the terminal executes one of the following steps: determining configuration or scheduling errors of network side equipment, wherein the terminal performs uplink transmission on the target symbol without receiving downlink transmission, cancels the uplink transmission on the target symbol, determines the type of the target symbol as downlink, and performs downlink reception on the target symbol.

For example, for the same symbol, the reference cell or the tdd-UL-DL-configuration command or the tdd-UL-DL-configuration configured configures the symbol as D or the higher layer signaling configuration terminal receives downlink transmission such as PDCCH, PDSCH, CSI-RS on the symbol; and the dynamic signaling of other cells or cell 2 is that the DCI schedules uplink transmission or the DCI indicates that the symbol is U, the terminal performs one of the following:

this is considered to be the configuration/scheduling of network errors;

make uplink transmission or not receive downlink transmission;

cancel the upstream transmission;

consider the symbol as D or perform downstream reception.

By the possible implementation manner, the configuration terminal is allowed to detect the downlink control information format 2_0 in other cells or the cell 2, so that the problem that the configuration of the downlink control information format 2_0 (DCI format 2_0) on any carrier is not supported in the related art is solved.

In another possible implementation manner, after the terminal determines the reference cell corresponding to the first time from the configured plurality of serving cells, the method may further include: when the type of the target symbol configured by the TDD uplink and downlink configuration common signaling or the TDD uplink and downlink configuration specific signaling of the first cell is uplink, or the high-layer signaling configures the terminal to perform uplink transmission on the target symbol, the second dynamic signaling of the second cell indicates that one of the following is executed by the terminal under the condition that the target symbol schedules downlink transmission or the second dynamic signaling indicates that the type of the target symbol is downlink: determining configuration or scheduling errors of network side equipment, performing downlink receiving and uplink transmission canceling by the terminal on the target symbol, not receiving downlink transmission by the terminal on the target symbol, determining the type of the target symbol as uplink by the terminal, and performing uplink transmission by the terminal on the target symbol.

For example, the reference cell or the tdd-UL-DL-configuration command or the tdd-UL-DL-configuration configured configures the symbol to be U or the higher layer signaling configuration terminal performs uplink transmission on the symbol, such as PUCCH, PUSCH, SRS, PRACH; while the dynamic signaling of other cells or cell 2 is that the DCI schedules the downlink transmission or that the DCI indicates that the symbol is D, the terminal performs one of the following:

this is considered to be the configuration/scheduling of network errors;

downlink reception or cancellation of uplink transmission;

no downlink transmission is received;

consider the symbol to be U or to be transmitted upstream.

Optionally, in the possible implementation manner, in a case that the higher layer signaling configures the terminal to perform uplink transmission on the target symbol, and the terminal cancels uplink transmission on the target symbol, a time from a first symbol where the second dynamic signaling is located to a second symbol where uplink transmission is cancelled is not less than a third time, where the third time is determined by a capability of the terminal or is agreed by a protocol.

For example, in the above possible implementation manner, when the terminal determines to cancel the uplink transmission, it is required to satisfy the processing time for the terminal to cancel the whole or part of the uplink transmission, that is, the time from the symbol where the downlink transmission is scheduled or the DCI indicating the downlink symbol is located to cancel the symbol where the whole or part of the uplink transmission is located > =the third time. Wherein the third time may be determined by the terminal capabilities or agreed upon by the protocol.

In another possible implementation manner, after the terminal determines the reference cell corresponding to the first time from the configured plurality of serving cells, the method may further include: in the case that the type of the TDD uplink and downlink configuration common signaling or the TDD uplink and downlink configuration specific signaling configuration target symbol of the first cell is a first type, and the higher layer signaling configuration of the second cell performs transmission different from the first type on the target symbol, the terminal performs one of the following: and determining network side equipment configuration or scheduling errors, transmitting on the target symbol according to the configuration of the high-layer signaling, and determining the type of the target symbol as a first type.

For example, for the same symbol, the tdd-UL-DL-configuration command or tdd-UL-DL-configuration configured of the reference cell or cell 1 configures the symbol as D or U, and higher layer signaling configuration terminals of other cells or cell 2 perform uplink transmission such as PUCCH, PUSCH, SRS, PRACH or receive downlink transmission such as PDCCH, PDSCH, CSI-RS or the like on the symbol, the terminal performs one of the following:

This is considered to be the configuration/scheduling of network errors;

downlink reception or uplink transmission, i.e. based on the downlink reception or uplink transmission configured on the symbol according to the higher layer signaling configuration, allowing RRC configured UL or DL to rewrite the direction of the tdd-UL-DL-configuration command/configured configuration;

consider the symbol to be either D or U, i.e. to be in accordance with the tdd-UL-DL-configuration command or tdd-UL-DL-configuration defined of the reference cell or cell 1.

By the scheme of conflict processing in different directions, the method can allow the tdd-UL-DL-configuration Common to indicate that there is conflict/allow the downlink symbol indicated by the tdd-UL-DL-configuration Common to be changed into an uplink symbol, and the uplink symbol is changed into a downlink symbol, so that the network side is not required to avoid the direction (uplink and downlink conflicts) of configuring or scheduling conflict on different carriers, the configuration/scheduling limitation of the network side is avoided, the flexibility of network configuration and scheduling is ensured, and the terminal can coexist with other terminals.

Based on the same concept, the embodiment of the present application further provides another method for configuring time division multiplexing carrier aggregation, fig. 5 shows another flow chart of the method for configuring time division multiplexing carrier aggregation in the embodiment of the present application, and the method 500 may be performed by a network side device. In other words, the method may be performed by software or hardware installed on the network-side device. As shown in fig. 5, the method may include the following steps.

S510, the network side equipment receives first capability information sent by a terminal, wherein the first capability information indicates that the terminal has the following capabilities: half duplex operation is supported in TDD CA with serving cells of non-identical SCS.

Wherein the terminal may send the first capability information in the manner described in method 400. The first capability information is the same as the first capability information in the method 400, and specific reference may be made to the description of the method 400.

In one possible implementation, the half-duplex operation includes: and processing directional conflict between a reference cell and other cells, wherein the other cells are serving cells except the reference cell in the TDD CA.

a SCS combination supported by the terminal, the SCS combination including a plurality of different SCSs;

the SCS of the reference cell supported by the terminal is the largest SCS in the SCS combination supported by the terminal;

the SCS of the reference cell supported by the terminal is the smallest SCS of the SCS combination supported by the terminal.

And S512, the network side equipment sends configuration information to the terminal according to the first capability information, wherein the configuration information is used for configuring a target TDD CA for the terminal, and SCSs of a plurality of service cells configured in the target TDD CA are not identical.

In one possible implementation, the terminal does not expect that the downlink time unit configured on the serving cell with the first SCS in the target TDD CA overlaps with the uplink time unit configured on the serving cell with the second SCS partially or entirely, wherein the first SCS is different from the second SCS.

In one possible implementation manner, since the terminal does not expect that the downlink time unit configured on the serving cell with the first SCS in the target TDD CA overlaps with the uplink time unit configured on the serving cell with the second SCS partially or completely, in this possible implementation manner, the network side device sends configuration information to the terminal according to the first capability information, including: the network side equipment determines the configuration information according to the first capability information, wherein the configuration information is used for configuring a service cell in the target TDD CA and a downlink time unit and/or an uplink time unit of the service cell in the target TDD CA, and the downlink time unit configured on the service cell with the first SCS and the uplink time unit configured on the service cell with the second SCS are not overlapped.

For example, the configuration of the network cannot be such that the DL or UL slots/symbols (symbols) configured on the serving cell of the larger SCS overlap with the UL or DL slots/symbols of any other serving cell with the smaller SCS in part.
