Description

Data transmission method and device
Technical Field
The present application relates to the field of communications technologies, and in particular, to a data transmission method and apparatus.
Background
Existing communication systems propose that uplink transmission performance can be improved by transmitting one large Transport Block (TB) over multiple time slots. Specifically, small transport blocks originally on multiple slots may be aggregated into one large multi-slot transport block (TBoMS). Compared with a plurality of small transmission blocks, the TBoMS can reduce the packet header overhead, realize the channel coding gain and improve the decoding performance and the transmission rate.
Since there may be some signal transmission resource conflicts, i.e. resource overlap, during the communication process. When the terminal device does not have the capability of simultaneously transmitting the signals, some rules may be defined, such as which signals are preferentially transmitted when overlapping occurs, so as to ensure that the network device and the terminal device understand in a consistent manner, so that communication can be performed normally.
Existing rules for resource overlap are only applicable to small transport blocks on a single slot and are not applicable to TBoMS. Therefore, how to handle resource overlapping when the terminal device performs uplink transmission by using the TBoMS method becomes an urgent problem to be solved.

Detailed Description
Prior to describing the embodiments of the present application, technical terms related to the embodiments of the present application will be described.
And (3) high-layer signaling: may refer to signaling by a higher protocol layer. The higher layer protocol layer may be at least one protocol layer above the physical layer. The higher layer protocol layer may specifically include at least one of the following protocol layers: a Medium Access Control (MAC) layer, a Radio Link Control (RLC) layer, a Packet Data Convergence Protocol (PDCP) layer, a Radio Resource Control (RRC) layer, and a non-access stratum (NAS) layer.
Multi-slot transport block over multi-slot (TBoMS): including Transport Blocks (TBs) over multiple slots.
In the uplink transmission process of the communication system, the uplink transmission capability of the terminal device is limited, for example: compared with downlink transmission, the transmission performance of uplink transmission faces greater challenges, and especially the uplink transmission performance of terminal equipment deteriorates rapidly in long-distance and deep fading scenes. In some deep coverage scenarios, such as cell edge, basement, etc., the path loss of wireless signal propagation is severe. In order to improve the uplink transmission performance, the communication system proposes that uplink transmission can be performed by using a TBoMS.
As shown in fig. 1, a terminal device may calculate a Transport Block Set (TBS) based on resources in multiple time slots, and map the TBS to multiple time slots for transmission, that is, aggregate TBS in multiple time slots into one TBoMS for transmission. Compared with a plurality of small transmission blocks, the method can reduce the packet header overhead, realize the channel coding gain of channel coding after the plurality of small transmission blocks are aggregated into the TBoMS, and improve the decoding performance and the transmission rate of uplink transmission.
Because there may be some conflicts of transmission resources of signals, that is, resource overlapping, in the communication process, when the terminal device does not have the capability of transmitting these signals simultaneously, some rules may be defined, for example, which signals are preferentially transmitted when overlapping occurs, so as to ensure that understanding of the network device and the terminal device is consistent, and ensure normal operation of communication.
For example, taking a terminal device sending a physical downlink shared channel (PUSCH) as an example, when a transmission resource of the PUSCH overlaps with any of the following resources, transmission of the PUSCH may be cancelled: a semi-statically configured downlink slot or symbol, a time domain resource occupied by a Physical Uplink Control Channel (PUCCH), a time domain resource occupied by a PUCCH having a higher priority than the PUSCH, and a semi-statically configured downlink slot or symbol on a reference cell or other cells in carrier aggregation.
When the terminal device performs uplink transmission by using a TBoMS, the TBoMS corresponding to multiple time slots may be used as a physical downlink shared channel (PUSCH), and when the transmission of the PUSCH is cancelled due to resource overlapping, the TBoMS may be cancelled, which may cause uplink resources to be wasted and affect uplink coverage.
For example, as shown in fig. 2, taking four timeslots for TBoMS as an example, assuming that only the second timeslot has resource overlap, it is necessary to cancel the transmission of the entire TBoMS, i.e., cancel the TBoMS on the four timeslots, which results in the waste of uplink resources.
In another example, taking the terminal device sending the PUSCH as an example, when the PUSCH in the semi-static configuration overlaps with the downlink symbol dynamically indicated by the Downlink Control Information (DCI), and when the terminal device does not support partial cancellation, if the starting symbol of the PUSCH is T after the last symbol of the DCI proc,2 And in time, not canceling the PUSCH transmission, otherwise, canceling the PUSCH transmission. When the terminal device supports partial cancellation, only T after the last symbol of DCI may be cancelled proc,2 The PUSCH transmission after the time may not be cancelled before.
In the method, a scheduling network device may send a Physical Downlink Control Channel (PDCCH) to a terminal device, and the PDCCH may schedule PUSCH transmission of uplink data, that is, the PDCCH may indicate a (physical downlink shared channel, PDSCH) or a time domain resource of the PUSCH. The second is a configured grant scheduling, which may include 2 types, a configured grant type 1 (configured grant type 1) and a configured grant type 2 (configured grant type 2), where the scheduling manner of the configured grant type 2 is similar to that of the first scheduling manner, that is, the network device sends a PDCCH to the terminal device to activate the configured grant scheduling, and the terminal device sends a PUSCH according to higher-layer configuration information; for the configuration grant type 1, the network device does not send PDCCH to the terminal device, and the position of the time domain resource occupied by PUSCH transmission may be configured through higher layer signaling.
Wherein, T proc,2 =max((N 2 +d 2,1 +d 2 )(2048+144)·κ2 ·T c +T ext +T switch ,d 2,2 )。
Wherein, N 2 Is a μ -based PUSCH preparation time determined from a PUSCH preparation time in PUSCH timing capability 1 shown in table 1 below and a PUSCH preparation time in PUSCH timing capability 2 shown in table 2 below. Mu can correspond to one of (mu DL, mu UL), and the value of mu can satisfy T proc,2 Taking the maximum value. μ DL corresponds to the subcarrier spacing of the PDCCH scheduling PUSCH, and μ UL corresponds to the subcarrier spacing of the uplink channel transmitting PUSCH. D if the first symbol of PUSCH contains only demodulation reference signal (DM-RS), then 2,1 =0, otherwise d 2,1 =1. D of high priority PUSCH if resource overlap occurs between high priority PUSCH and low priority PUCCH 2 Can be set by reporting the value on the terminal equipment, otherwise d 2 =0. K is equal to 64.T is c May be equal to 1/(480 x 10 x 3 x 4096), T c The unit of (d) may be seconds(s). For handling of non-shared spectrum channel access, T ext =0。T switch Indicating the switching time. If scheduling DCI triggers a partial Bandwidth part (BWP) switch, d 2,2 Equals the switching time, otherwise d 2,2 =0。

When the terminal equipment adopts the TBoMS mode to perform uplink transmission, the TBoMS corresponding to a plurality of time slots can be used as a PUSCH, and when the PUSCH transmission is cancelled due to resource overlapping and the terminal equipment does not support partial cancellation, if the starting symbol of the TBoMS is T after the last symbol of the DCI proc,2 And in time, the TBoMS transmission can not be cancelled, otherwise, the TBoMS transmission is cancelled. When the terminal device supports partial cancellation, only T after the last symbol of DCI may be cancelled proc,2 The TBoMS transmission after the time may not be cancelled before. When the TBoMS is cancelled, uplink resources are wasted, affecting uplink coverage.
For example, as shown in fig. 3, taking four time slots corresponding to TBoMS as an example, assuming that resource overlapping occurs only in the second time slot, when the terminal device does not support partial cancellation, if the starting symbol of TBoMS is T after the last symbol of DCI proc,2 TBoMS transmission may not be cancelled for the time, otherwise, if the starting symbol of TBoMS is T after the last symbol of DCI proc,2 And canceling TBoMS transmission outside the time. When the terminal device supports partial cancellation, only T after the last symbol of DCI may be cancelled proc,2 The TBoMS transmission after the time may not be cancelled before, for example, the TBoMS transmission may be cancelled from the second half of the second slot, and not cancelled before. When the TBoMS is cancelled, uplink resources are wasted, affecting uplink coverage.
In still another example, taking the terminal device sending the PUSCH as an example, when the time domain resource occupied by the PUSCH includes the time domain resource indicated by the network device to cancel the PUSCH transmission, the terminal device cancels the PUSCH transmission after the symbol indicated to cancel the PUSCH transmission in the first time domain resource occupied by the PUSCH.
The network device may send cancellation indication information (cancellation indication) to the terminal device, where the cancellation indication information may indicate, by using a bitmap, which time domain resource positions of the PUSCH are to be cancelled within a certain time domain resource, and may cancel PUSCH transmission by setting a bit to 1 to indicate a time domain position corresponding to the bit. If at least one symbol in the time domain resource occupied by the PUSCH is indicated as 1, starting from the first symbol indicated as 1 in the time domain resource occupied by the PUSCH, and canceling all the following PUSCH transmissions.
For example, taking symbol 2 to symbol 12 of a slot occupied by PUSCH as an example, assuming symbol 3 and symbol 4 are indicated as 1, symbol 2 reserves PUSCH transmission, and PUSCH transmission starting from symbol 3 to symbol 12 is cancelled all together.
When the terminal device performs uplink transmission in a TBoMS manner, the TBoMS corresponding to multiple slots may be used as a PUSCH, and when the network device sends cancellation indication information to the terminal device, if the time domain resource occupied by the TBoMS includes the time domain resource instructed to cancel transmission by the network device, the terminal device may cancel TBoMS transmission after the first symbol instructed to cancel transmission in the time domain resource occupied by the TBoMS. Because the TBoMS occupies a plurality of time slots, when the terminal device cancels TBoMS transmission, uplink resources are wasted, and uplink coverage is affected.
For example, as shown in fig. 4, taking four timeslots corresponding to TBoMS as an example, assuming that only the second timeslot includes the time domain resource for cancelled transmission indicated by the network device, and the last symbol in the time domain resource for cancelled transmission indicated by the network device is indicated as 1, the terminal device may cancel the last symbol and the TBoMS transmission after the last symbol, which results in uplink resource being wasted and uplink coverage being affected.
In summary, how to handle resource overlapping, improve the utilization rate of resources, and improve uplink coverage when the terminal device performs uplink transmission in the TBoMS manner is an urgent problem to be solved.
Based on the foregoing problems, an embodiment of the present application provides a data transmission method, which may include: the terminal equipment acquires information of time domain resources occupied by a multi-slot transmission block TBoMS, and cancels the transmission of the TBoMS on a second time domain resource or a third time domain resource when the time domain resources occupied by the TBoMS are overlapped with the first time domain resources; the second time domain resource is a part of time domain resources in the time domain resources occupied by the TBoMS, the third time domain resource is a time domain resource of which the time domain resources occupied by the TBoMS and the first time domain resources are overlapped, and the third time domain resource is a part of time domain resources of the second time domain resources.
In the embodiment of the application, when the time domain resource occupied by the TBoMS overlaps with the first time domain resource, the terminal device can perform normal communication by cancelling the TBoMS transmission on the second time domain resource or the third time domain resource. In addition, the whole TBoMS can be avoided being cancelled, so that the resource utilization rate is improved, and the uplink coverage is improved.

With reference to fig. 7 below, a description is given of a data transmission method provided in an embodiment of the present application with reference to the communication system shown in fig. 5, where a terminal device may be any terminal device in the communication system shown in fig. 5, and a network device may be any network device in the communication system shown in fig. 5. The terminal device and the network device described in the following embodiments may each have the components shown in fig. 6. The processing performed by a single execution main body (terminal device or network device) shown in the embodiments of the present application may also be divided into execution by a plurality of execution main bodies, which may be logically and/or physically separated, for example, the processing performed by the network device may be divided into execution by at least one of a Central Unit (CU), a Distributed Unit (DU), and a Radio Unit (RU).
Fig. 7 is a flowchart of a data transmission method according to an embodiment of the present application, and as shown in fig. 7, the method may include:
step 701, the terminal device obtains information of a time domain resource occupied by the TBoMS.
The terminal device may receive third indication information sent by the network device, where the third indication information may be used to indicate a position of a symbol occupied by the TBoMS in each slot.
For example, the network device may indicate a plurality of time domain resources to the terminal device in advance in a table form, the table may include a plurality of rows, each row may include a starting symbol and a number of symbols, and the time domain resource indicated by the current row may be determined according to the starting symbol and the number of symbols of the current row, that is, each row of the table may be used to indicate one time domain resource.
The third indication information may include a row index, and the terminal device may determine the time domain resource indicated by the row according to the row index.
For example, taking a table sent by the network device to the terminal device includes 16 rows, and taking as an example that 16 time domain resources are respectively indicated, 4 bits may be adopted as a row index to indicate the 16 time domain resources, that is, the row index may be 0000, 0001, \ 8230;, and 1111, assuming that the network device sends the row index 0000 carried in the third indication information to the terminal device, and the terminal device may determine, according to the third indication information, that a symbol position occupied by the TBoMS in each time slot is a time domain resource position indicated by the first row in the table.
Optionally, each row of the table further includes fourth indication information.
The fourth indication information may be used to indicate the number of time slots occupied by the TBoMS, and the terminal device may determine the number of time slots occupied by the TBoMS according to the fourth indication information.
For example, taking the row indicated by the row index as including the starting symbol of 2, the number of symbols of 12, and the number of slots occupied by TBoMS of 4 as an example, as shown in fig. 8, it may be determined that all of symbols 2 to 13 of each slot are time domain resources occupied by TBoMS.
It should be noted that the network device may send the third indication information carried by the row index to the terminal device, so that the terminal device determines the fourth indication information according to the table and the row index. The network device may also carry the fourth indication information in a high-level signaling and send the high-level signaling to the terminal device, so that the terminal device determines the fourth indication information according to the high-level signaling.
Optionally, the network device may further send fifth indication information to the terminal device.
Wherein, the fifth indication information is used for indicating the position of the starting time slot of the TBoMS.
For example, the network device may determine the position of the starting slot of the TBoMS based on the DCI sent to the terminal device. For example, the network device may instruct the terminal device to use the nth slot after the last symbol of the received DCI as the starting slot of the TBoMS, that is, the fifth indication information is used to indicate the nth slot after the last symbol of the DCI.
It should be noted that the network device may carry the fifth indication information in the third indication information and send the third indication information to the terminal device, or may carry the fifth indication information in the higher layer signaling and send the higher layer signaling to the terminal device, which is not limited.
Optionally, the terminal device further receives sixth indication information sent by the network device.
The sixth indication information may be used to indicate the terminal device to perform uplink transmission in a TBoMS manner, and the terminal device may determine, based on the sixth indication information, a time domain resource occupied by the TBoMS and perform uplink transmission in a TBoMS manner.
Step 702, when the time domain resource occupied by the tbomms overlaps with the first time domain resource, the terminal device cancels the tbomms transmission on the second time domain resource or the third time domain resource.
The first time domain resource may be any one of the following time domain resources: the uplink resource allocation method comprises the steps of semi-statically allocated downlink time slots or symbols, time domain resources occupied by repeated PUCCHs, time domain resources occupied by PUCCHs with priority higher than TBoMS, and semi-statically allocated downlink time slots or symbols on a reference cell or other cells in carrier aggregation.
The second time domain resource may be a partial time domain resource in the time domain resources occupied by the tbos, the third time domain resource may be a time domain resource in which the time domain resources occupied by the tbos and the first time domain resource are overlapped, and the third time domain resource may be a partial time domain resource of the second time domain resource.
Specifically, the time domain resource occupied by the tbos may be divided into a plurality of second time domain resources, and it is determined whether each of the second time domain resources includes a time domain resource in which the time domain resource occupied by the tbos overlaps with the first time domain resource, and if the time domain resource occupied by the tbos includes the time domain resource, the transmission of the tbos on the second time domain resource is cancelled, or the transmission of the tbos on a third time domain resource in the second time domain resource is cancelled, otherwise, the tbos is normally transmitted on the second time domain resource.
It should be noted that, when the time domain resource occupied by the TBoMS and the time domain resource where the first time domain resource is overlapped occupy the entire second time domain resource, the third time domain resource may also be described as the second time domain resource.
Illustratively, the second time domain resource may be one or more of: one or more time slots, one or more symbols, a time domain resource occupied by the TBoMS on one time slot, and a time domain allocation of a TBoMS (TOT).
The terminal device may determine the time domain resource occupied by the TBoMS in a time slot according to the starting symbol and the number of symbols.
The time domain resource occupied by the TOT may be any one of the following time domain resources: time domain resources occupied by one redundancy version of the TBoMS, time domain resources corresponding to one time granularity for carrying out bit selection and bit interleaving in the TBoMS, and time domain resources corresponding to a time unit for carrying out rate matching by the TBoMS.
The time domain resource occupied by the TOT may be preconfigured by higher layer signaling, or may be indicated by the higher layer signaling, or may be determined by the terminal device according to a certain rule.
Illustratively, the certain rule may be: the TOT specified by the communication protocol is used. At this time, the terminal device may determine the time domain resource occupied by the TOT according to the communication protocol.
It should be noted that, when the network device communicates with the terminal device, the second time domain resource used may be specifically which time domain resource is pre-agreed by the communication protocol, or may be configured by the network device through a high-level signaling, which is not limited.
In addition, when the time domain resource occupied by the TBoMS overlaps with the first time domain resource, the terminal device may determine to cancel the transmission of the TBoMS on the second time domain resource according to the pre-agreement of the communication protocol, or cancel the transmission of the TBoMS on the third time domain resource according to the pre-agreement of the communication protocol. Or, the terminal device may also determine to cancel the TBoMS transmission on the second time domain resource according to the pre-configuration of the network device, or cancel the TBoMS transmission on the third time domain resource according to the pre-configuration of the network device.
Optionally, when the terminal device supports partial cancellation, the terminal device cancels TBoMS transmission on the second time domain resource or the third time domain resource. And when the terminal equipment does not support the partial cancellation, the terminal equipment cancels the transmission of the TBoMS.
The terminal device may send first indication information to the network device, where the first indication information may be used to indicate whether the terminal device supports partial cancellation. Or, the terminal device may also receive second indication information from the network device; the second indication information is used for indicating whether the terminal equipment supports partial cancellation.
It should be noted that, after the terminal device sends the first indication information to the network device, the network device may also send second indication information to the second terminal device to indicate whether the terminal device supports partial cancellation.
Illustratively, the terminal device sends first indication information for indicating that the terminal device supports partial cancellation to the network device, after the network device receives the first indication information, if the terminal device is not considered to support partial cancellation, the network device may send second indication information for indicating that the terminal device does not support partial cancellation to the terminal device, and after the terminal device receives the second indication information, according to the second indication information, when resource overlapping occurs, the terminal device cancels tbomms transmission.
Based on the above steps 701 and 702, the step 702 is described in detail with reference to the following four examples.
In a first example, taking the first time domain resource as a semi-statically configured downlink time slot or symbol as an example, when the time domain resource occupied by the tbos overlaps with the semi-statically configured downlink time slot or symbol, the terminal device may cancel the tbos transmission on the second time domain resource or the third time domain resource.
The network device may configure a frame structure for the terminal device by sending a high-layer signaling to the terminal device, that is, which slots or symbols are configured as a downlink, which slots or symbols are configured as an uplink, and which slots or symbols are configured as flexible. The time slot or symbol configured as the downlink can only transmit downlink signals, the time slot or symbol configured as the uplink can only transmit uplink signals, and the symbol configured as the flexible can sometimes transmit uplink signals and sometimes transmit downlink signals.
The higher layer signaling may be uplink and downlink timeslot configuration (tdd-UL-DL-configuration common) at a cell level and uplink and downlink timeslot configuration (tdd-UL-DL-configuration determined) specific to the UE.
For example, taking the case that when the time domain resource occupied by the TBoMS overlaps with the semi-statically configured downlink time slot or symbol, the terminal device cancels the transmission of the TBoMS on the second time domain resource, and it is assumed that the TBoMS occupies four time slots, the second time domain resource is the time domain resource occupied by the TOT, and each time domain resource occupied by the TOT includes two time slots, as shown in (a) in fig. 9, when the time domain resource occupied by the semi-statically configured downlink time slot or symbol and the time domain resource occupied by the TBoMS overlaps on the second time slot, the terminal device may cancel the transmission of the TBoMS on the first TOT, and reserve the transmission of the TBoMS on the second TOT, that is, the terminal device cancels the transmission of the TBoMS on the first time slot and the second time slot, and reserve the transmission of the TBoMS on the third time slot and the fourth time slot.
In another example, taking as an example that when the time domain resource occupied by the tbos overlaps with the semi-statically configured downlink timeslot or symbol, the terminal device cancels transmission of the tbos on the third time domain resource, assuming that the tbos occupies four timeslots, the second time domain resource is the time domain resource occupied by the TOT, and each time domain resource occupied by the TOT includes two timeslots, as shown in (b) in fig. 9, when the semi-statically configured downlink timeslot or symbol overlaps with the time domain resource occupied by the tbos on the second timeslot, the terminal device may cancel transmission of the tbos on the third time domain resource, reserve transmission of the tbos on other time domain resources of the tbos, that is, the terminal device cancels transmission of the tbos on the time domain resource overlapped by the resource in the second timeslot, and reserve transmission of the tbos on the first timeslot, the time domain resource not overlapped by the resource in the second timeslot, the third timeslot, and the fourth timeslot.
In yet another possible design, as shown in fig. 9 (c), the terminal device may also cancel the TBoMS transmission on the time slot where the third time domain resource is located, that is, the terminal device cancels the TBoMS transmission on the second time slot, and reserves the TBoMS transmission on the first time slot, the third time slot, and the fourth time slot.
In a second example, taking the first time domain resource as the time domain resource occupied by the repeated PUCCH as an example, when the time domain resource occupied by the TBoMS and the time domain resource occupied by the repeated PUCCH are overlapped, the terminal device may cancel the TBoMS transmission on the second time domain resource or the third time domain resource.
For example, taking the example that when the time domain resource occupied by the TBoMS overlaps with the time domain resource occupied by the repeated PUCCH, the terminal device cancels transmission of the TBoMS on the second time domain resource, assuming that the TBoMS occupies six time slots, the second time domain resource is the time domain resource occupied by the TOT, and each time domain resource occupied by the TOT includes two time slots, as shown in (a) in fig. 10, when the time domain resource occupied by the repeated PUCCH overlaps with the time domain resource occupied by the TBoMS on the first time slot and the third time slot, the terminal device may cancel transmission of the TBoMS on the first TOT and the second TOT, and reserve transmission of the TBoMS on the third TOT, that is, the terminal device cancels transmission of the TBoMS on the first time slot, the second time slot, the third time slot, and the fourth time slot, and reserve transmission of the TBoMS on the fifth time slot and the sixth time slot.
In another example, taking as an example that when the time domain resource occupied by the TBoMS overlaps with the time domain resource occupied by the repeated PUCCH, the terminal device cancels transmission of the TBoMS on the third time domain resource, assuming that the TBoMS occupies six time slots, the second time domain resource is the time domain resource occupied by the TOT, and each time domain resource occupied by the TOT includes two time slots, as shown in (b) in fig. 10, when the time domain resource occupied by the repeated PUCCH overlaps with the time domain resource occupied by the TBoMS on the second time slot, the terminal device may cancel transmission of the TBoMS on the third time domain resource, reserve transmission of the TBoMS on other time domain resources of the TBoMS, that is, the terminal device cancels transmission of the TBoMS on the time domain resource overlapped with the resource in the first time slot and the third time slot, reserve transmission of the TBoMS on the first time slot and the third time slot without resource overlapped, and transmission of the second time slot, the fourth time slot, the fifth time slot and the sixth time slot.
In still another possible design, as shown in fig. 10 (c), the terminal device may also cancel the transmission of the TBoMS in the time slot where the third time domain resource is located, that is, the terminal device cancels the transmission of the TBoMS in the first time slot and the third time slot, and reserves the transmission of the TBoMS in the second time slot, the fourth time slot, the fifth time slot, and the sixth time slot.
In a third example, taking the first time domain resource as the time domain resource occupied by the PUCCH with priority higher than the TBoMS as an example, when the time domain resource occupied by the TBoMS and the time domain resource occupied by the PUCCH with priority higher than the TBoMS are overlapped, the terminal device may cancel the TBoMS transmission on the second time domain resource or the third time domain resource.
Here, the priority of the PUCCH may be indicated by DCI scheduling the PDSCH or configured by higher layer signaling, that is, there is a way to determine whether the priority of a certain PUCCH is high priority or low priority. The priority of the TBoMS may be indicated by DCI or may be configured by higher layer signaling.
For example, taking the example that when the time domain resource occupied by the TBoMS overlaps the time domain resource occupied by the PUCCH with priority higher than the TBoMS, the terminal device cancels transmission of the TBoMS on the second time domain resource, assuming that the TBoMS occupies four time slots, the second time domain resource is the time domain resource occupied by the TOT, and each time domain resource occupied by the TOT includes two time slots, as shown in (a) in fig. 11, when the time domain resource occupied by the PUCCH with priority higher than the TBoMS overlaps the time domain resource occupied by the TBoMS on the third time slot, the terminal device may cancel transmission of the TBoMS on the second TOT, and reserve transmission of the TBoMS on the first TOT, that is, the terminal device cancels transmission of the TBoMS on the third time slot and the fourth time slot, and reserves transmission of the TBoMS on the first time slot and the second time slot.
In another example, taking as an example that when the time domain resource occupied by the TBoMS overlaps with the time domain resource occupied by the PUCCH having a higher priority than the TBoMS, the terminal device cancels transmission of the TBoMS on the third time domain resource, and assuming that the TBoMS occupies four time slots, the second time domain resource is the time domain resource occupied by the TOT, and each time domain resource occupied by the TOT includes two time slots, as shown in (b) in fig. 11, when the time domain resource occupied by the PUCCH having a higher priority than the TBoMS overlaps with the time domain resource occupied by the TBoMS on the third time slot, the terminal device may cancel transmission of the TBoMS on the third time domain resource, reserve transmission of the TBoMS on other time domain resources of the TBoMS, that is, the terminal device cancels transmission of the TBoMS on the time domain resource overlapping in the third time slot, reserve transmission of the first time slot, the second time slot, the time domain resource overlapping with no resource in the third time slot, and transmission of the TBoMS on the fourth time slot.
In still another possible design, as shown in fig. 11 (c), the terminal device may also cancel the transmission of the TBoMS in the time slot where the third time domain resource is located, that is, the terminal device cancels the transmission of the TBoMS in the third time slot, and reserves the transmission of the TBoMS in the first time slot, the second time slot, and the fourth time slot.
In a fourth example, taking the first time domain resource as the downlink timeslot or symbol statically configured on the reference cell or on the other cell in the carrier aggregation as an example, when the time domain resource occupied by the tbos overlaps with the downlink timeslot or symbol statically configured on the reference cell or on the other cell in the carrier aggregation, the terminal device may cancel the transmission of the tbos on the second time domain resource or the third time domain resource.
If the terminal device configures multiple cells and configures a half-duplex behavior equal to start (half-duplex-beacon = 'enable') to indicate that half-duplex collision processing needs to be performed, and the terminal device does not have the capability of supporting simultaneous transceiving in any cell, and reports that the network device can support half-duplex operation and does not configure blind detection DCI format 2_0, when the following symbols overlap with time domain resources occupied by TBoMS, the terminal device may cancel TBoMS transmission on the second time domain resources or the third time domain resources:
1. if this symbol is indicated in any one cell by the ssb-positions in burst field in system information block 1 (sib1) signaling or in serving cell common configuration (serving cell common) signaling as a symbol for receiving a synchronization/broadcast data (SS/PBCH) block.
2. If the symbol is configured in the reference cell by the uplink and downlink time slot of the cell level or the uplink and downlink time slot configuration parameter dedicated to the UE, the symbol becomes downlink, or is configured by the higher layer signaling to receive the symbol of PDCCH, PDSCH, or channel state information-reference signal (CSI-RS).
For example, taking the example that when the time domain resources occupied by the TBoMS overlap with the downlink time slots or symbols statically configured on the reference cell or on the upper half of the other cells in the carrier aggregation, the terminal device cancels the transmission of the TBoMS on the second time domain resources, assuming that the TBoMS occupies four time slots, the second time domain resources are time domain resources occupied by the TOTs, and each time domain resource occupied by the TOTs includes two time slots, as shown in (a) in fig. 12, when the downlink time slots or symbols statically configured on the reference cell or on the upper half of the other cells in the carrier aggregation overlap with the time domain resources occupied by the TBoMS on the second time slot, the terminal device may cancel the transmission of the TBoMS on the first TOT, reserve the transmission of the TBoMS on the second TOT, that is, the terminal device cancels the transmission of the TBoMS on the first time slot and the TBoMS on the fourth time slot.
In yet another example, taking as an example that when the time domain resource occupied by the TBoMS overlaps with the downlink time slot or symbol statically configured on the reference cell or on the other cell in the carrier aggregation, the terminal device cancels transmission of the TBoMS on the third time domain resource, assuming that the TBoMS occupies four time slots, the second time domain resource is the time domain resource occupied by the TOT, and each time domain resource occupied by the TOT includes two time slots, as shown in (b) in fig. 12, when the downlink time slot or symbol statically configured on the reference cell or on the other cell in the carrier aggregation overlaps with the time domain resource occupied by the TBoMS on the second time slot, the terminal device may cancel transmission of the TBoMS on the third time domain resource, and reserve transmission of the TBoMS on the other time domain resources of the TBoMS, that is, the terminal device cancels transmission of the TBoMS on the time domain resource overlapping with the resource in the second time slot, and reserves transmission of the time domain resource not overlapping with the first time slot and the second time slot, the third time slot, and the TBoMS on the fourth time slot.
In yet another possible design, as shown in fig. 12 (c), the terminal device may also cancel the TBoMS transmission on the time slot where the third time domain resource is located, that is, the terminal device cancels the TBoMS transmission on the second time slot, and reserves the TBoMS transmission on the first time slot, the third time slot, and the fourth time slot.
Based on the method shown in fig. 7, when the time domain resource occupied by the TBoMS overlaps with the first time domain resource, the terminal device cancels the TBoMS transmission on the second time domain resource or the third time domain resource, so that the communication can be performed normally. In addition, the whole TBoMS can be avoided being cancelled, so that the resource utilization rate is improved, and the uplink coverage is improved.
As shown in fig. 13, when the time domain resource occupied by the TBoMS overlaps with the first time domain resource, the network device does not receive the TBoMS on the second time domain resource or the third time domain resource, when the time domain resource occupied by the TBoMS overlaps with the first time domain resource, the terminal device cancels the TBoMS transmission on the second time domain resource or the third time domain resource.
Fig. 13 is a flowchart of a data transmission method according to an embodiment of the present application, and as shown in fig. 13, the method may include:
step 1301, the network device obtains information of time domain resources occupied by the TBoMS.
The description of the information of the time domain resource occupied by the TBoMS may refer to the related description in step 701, which is not repeated.
Step 1302, when the time domain resource occupied by the tbomms overlaps with the first time domain resource, the network device does not receive the tbomms on the second time domain resource or the third time domain resource.
The description of the first time domain resource, the second time domain resource, and the third time domain resource may refer to the relevant description in step 702, and is not repeated.
Optionally, when the network device determines that the terminal device supports partial cancellation, the network device does not receive the TBoMS on the second time domain resource or the third time domain resource. When the network equipment determines that the terminal equipment does not support the partial cancellation, the network equipment does not receive the TBoMS.
The network equipment can receive first indication information from the terminal equipment; the first indication information may be used to indicate whether the terminal device supports partial cancellation. Or, the network device may determine whether the terminal device supports partial cancellation by itself, and send second indication information to the terminal device, where the second indication information may be used to indicate whether the terminal device supports partial cancellation.
The description of the first indication information and the second indication information may refer to the related description in step 702, and is not repeated.
Based on the method shown in fig. 13, when the time domain resource occupied by the TBoMS overlaps with the first time domain resource, the terminal device may cancel the TBoMS transmission on the second time domain resource or the third time domain resource, and accordingly, the network device may not receive the TBoMS in the second time domain resource or the third time domain resource, so that the communication may be performed normally. In addition, the whole TBoMS can be avoided being cancelled, so that the resource utilization rate is improved, and the uplink coverage is improved.
Unlike the first time domain resources shown in fig. 7 to 13, as shown in fig. 14, when the time domain resource occupied by the TBoMS overlaps with the time domain resource occurrence resource indicated by the DCI, the terminal device may refer to the method shown in fig. 14 described below to process the TBoMS transmission.
Fig. 14 is a flowchart of a data transmission method according to an embodiment of the present application, and as shown in fig. 14, the method may include:
step 1401, the terminal device obtains information of time domain resources occupied by the multi-slot transport block TBoMS.
The description of step 1401 may refer to the description of step 701, and is not repeated.
Step 1402, the terminal device receives the DCI from the network device.
Wherein the DCI may be used to indicate the fourth time domain resource.
Specifically, the network device may carry one DCI format 2_0 by sending one PDCCH, where the DCI format may indicate that symbols (i.e., the fourth time domain resource) in one or more slots are uplink symbols or downlink symbols or flexible symbols. Or the DCI may schedule one PDSCH or CSI-RS on some symbols (i.e., the fourth time domain resource).
Step 1403, when the fourth time domain resource overlaps with the time domain resource occupied by the tbos, if the terminal device does not support partial cancellation and the distance between the last symbol of the DCI and the start symbol of the second time domain resource is greater than or equal to the first threshold, the terminal device cancels the tbos transmission on the second time domain resource.
The second time domain resource is a part of time domain resources in the time domain resources occupied by the TBoMS, and the second time domain resource comprises time domain resources of which the fourth time domain resources are overlapped with the time domain resources occupied by the TBoMS.
The description of the second time domain resource may refer to the related description in step 702, which is not repeated herein.
Wherein the first threshold may be T proc,2
For example, as shown in fig. 15, taking an example that a TBoMS occupies four time slots, and a second time domain resource is one time slot, when a resource overlap occurs between a fourth time domain resource and a time domain resource occupied by the TBoMS in the second time slot, assuming that the terminal device does not support partial cancellation, and a distance between a last symbol of DCI and a start symbol of the second time domain resource is greater than or equal to a first threshold, the terminal device may cancel TBoMS transmission in the second time domain resource where the resource overlap occurs, and reserve TBoMS transmission in other time domain resources, that is, cancel TBoMS transmission in the second time slot, and reserve TBoMS transmission in the first time slot, the third time slot, and the fourth time slot.
It should be noted that, if the terminal device does not support partial cancellation, and the distance between the last symbol of the DCI and the starting symbol of the second time domain resource is smaller than the first threshold, the terminal device does not cancel the TBoMS transmission on the second time domain resource.
For example, as shown in fig. 16, assuming that the terminal device does not support partial cancellation and the distance between the last symbol of the DCI and the starting symbol of the second time domain resource is smaller than the first threshold, the terminal device may not cancel the TBoMS transmission, i.e., the terminal device reserves the TBoMS transmission on the first slot, the second slot, the third slot, and the fourth slot.
Step 1404, when the fourth time domain resource overlaps with the time domain resource occupied by the tbos, if the terminal device supports partial cancellation, the terminal device cancels the tbos transmission after the first symbol in the second time domain resource.
Wherein a distance between the first symbol and a last symbol of the DCI may be a first threshold.
For example, as shown in fig. 17, taking a TBoMS occupying four time slots and a second time domain resource as one time slot as an example, when a resource overlap occurs between a fourth time domain resource and a time domain resource occupied by the TBoMS in a second time slot, assuming that the terminal device supports partial cancellation, the terminal device cancels transmission of the TBoMS after a first symbol in the second time domain resource where the resource overlap occurs, or is described as the terminal device cancels transmission of the TBoMS after a first threshold time after a last symbol of DCI in the second time domain resource where the resource overlap occurs. That is, the terminal device cancels the transmission of TBoMS after the first threshold time after the last symbol of DCI in the second slot.
In the above steps 1403 and 1404, the terminal device may send first indication information to the network device to indicate whether the terminal device supports partial cancellation, and the network device may also send second indication information to the terminal device to indicate whether the terminal device supports partial cancellation.
Based on the method shown in fig. 14, when the time domain resource occupied by the TBoMS overlaps with the fourth time domain resource, the terminal device may process the TBoMS transmission based on the above method, so that the communication may be performed normally. In addition, the whole TBoMS can be avoided being cancelled, so that the resource utilization rate is improved, and the uplink coverage is improved.
As shown in fig. 18, when the time domain resource occupied by the TBoMS overlaps with the fourth time domain resource, the network device may process the transmission of the TBoMS by referring to the method shown in fig. 18, corresponding to the processing of the transmission of the TBoMS by the terminal device when the time domain resource occupied by the TBoMS overlaps with the fourth time domain resource.
Fig. 18 is a data transmission method according to an embodiment of the present application, and as shown in fig. 18, the method may include:
step 1801, the network device obtains information of time domain resources occupied by the TBoMS.
The description of step 1801 may refer to the description of step 1401, and is not repeated herein.
Step 1802, the network device sends the DCI to the terminal device.
Wherein the DCI may be used to indicate the fourth time domain resource.
The description of step 1802 may refer to the description of step 1402, and is not repeated herein.
Step 1803, when the fourth time domain resource overlaps with the time domain resource occupied by the TBoMS, if the terminal device does not support partial cancellation, and the distance between the last symbol of the DCI and the start symbol of the second time domain resource is greater than or equal to the first threshold, the network device does not receive the TBoMS on the second time domain resource.
The second time domain resource is a part of time domain resource in the time domain resource occupied by the TBoMS, and the second time domain resource comprises a time domain resource of which the fourth time domain resource is overlapped with the time domain resource occupied by the TBoMS.
The description of the second time domain resource and the first threshold may refer to the related description in step 1403, which is not repeated herein.
Step 1804, when the fourth time domain resource overlaps with the time domain resource occupied by the TBoMS, if the terminal device supports partial cancellation, the network device does not receive the TBoMS after the first symbol in the second time domain resource.
And the distance between the first symbol and the last symbol of the DCI is a first threshold value.
The description of the first symbol may refer to the description related to step 1404, and is not repeated herein.
Based on the method shown in fig. 18, when the time domain resource occupied by the TBoMS overlaps with the fourth time domain resource, the network device may process the TBoMS transmission based on the above method, so that the communication may be performed normally. In addition, the whole TBoMS can be avoided being cancelled, so that the resource utilization rate is improved, and the uplink coverage is improved.
Unlike the first time domain resource and the fourth time domain resource shown in fig. 7 to 18, as shown in fig. 19, when the time domain resource occupied by the TBoMS includes the time domain resource indicated by the DCI for canceling the TBoMS transmission, the terminal device may refer to the method shown in fig. 19 described below to process the TBoMS transmission.
Fig. 19 is a data transmission method according to an embodiment of the present application, and as shown in fig. 19, the method may include:
step 1901, the terminal device obtains information of the time domain resource occupied by the TBoMS.
The description of step 1901 may refer to the description of step 701, and is not repeated herein.
Step 1902, the terminal device receives DCI from the network device.
Wherein the DCI may be used to indicate a time domain resource for which transmission of the TBoMS is cancelled.
For example, the network device may indicate the time domain resource of the cancelled TBoMS transmission by using a bitmap, for example, a bit may be set to 1 to indicate that the symbol corresponding to the bit is cancelled.
Step 1903, when the second time domain resource includes the time domain resource indicated by the DCI and canceled the tbos transmission, the terminal device cancels the tbos transmission after the second symbol in the second time domain resource.
The second time domain resource may be a part of time domain resources in the time domain resources occupied by the TBoMS, and the second symbol is a symbol of the first cancelled TBoMS, which is indicated by the DCI in the second time domain resource.
For example, as shown in fig. 20, taking a tbos occupying four slots, where the second time domain resource is one slot, when the second slot includes the time domain resource of the cancelled tbos indicated by the DCI, the terminal device cancels the transmission of the tbos after the second symbol in the second slot, and assuming that the second symbol is the last symbol of the time domain resource of the cancelled tbos indicated by the DCI, the terminal device cancels the transmission of the tbos after the second symbol in the second slot.
Based on the method shown in fig. 19, when the time domain resource occupied by the TBoMS includes the time domain resource indicated by the DCI for canceling the transmission of the TBoMS, the terminal device may process the transmission of the TBoMS based on the method, so that the communication may be performed normally. In addition, the whole TBoMS can be avoided being cancelled, so that the resource utilization rate is improved, and the uplink coverage is improved.
As shown in fig. 21, when the time domain resource occupied by the TBoMS includes the time domain resource indicated by the DCI for canceling the transmission of the TBoMS, the network device may process the transmission of the TBoMS by referring to the method shown in fig. 21, where the time domain resource occupied by the TBoMS includes the time domain resource indicated by the DCI for canceling the transmission of the TBoMS.
Fig. 21 is a data transmission method according to an embodiment of the present application, and as shown in fig. 21, the method may include:
step 2101, the network device obtains information of the time domain resource occupied by the TBoMS.
Step 2102, the network device sends the DCI to the terminal device.
Wherein the DCI may be used to indicate a time domain resource for which transmission of the TBoMS is cancelled.
Step 2103, when the second time domain resource includes the time domain resource of the cancelled TBoMS indicated by the DCI, the network device does not receive the TBoMS after the second symbol in the second time domain resource.
The second time domain resource is a part of time domain resources in the time domain resources occupied by the TBoMS, and the second symbol is a symbol of the first cancelled TBoMS in the DCI indication in the second time domain resources.
Based on the method shown in fig. 21, when the time domain resource occupied by the TBoMS includes the time domain resource indicated by the DCI for canceling the transmission of the TBoMS, the network device may process the transmission of the TBoMS based on the method, so that the communication may be performed normally. In addition, the whole TBoMS can be avoided being cancelled, so that the resource utilization rate is improved, and the uplink coverage is improved.
