Description

Data transmission method and device

This application claims the priority of the Chinese patent application with the application number 202110903256.3 and the application name "data transmission method and device" submitted to the State Intellectual Property Office on August 6, 2021, the entire contents of which are incorporated in this application by reference.

technical field

The present application relates to the technical field of communications, and in particular to a data transmission method and device.

Background technique

Existing communication systems propose that uplink transmission performance can be improved by transmitting a large transport block (transport block, TB) over multiple time slots. Specifically, the original small transport blocks on multiple time slots can be aggregated into a large multi-slot transport block (transport block over multi-slot, TBoMS). Compared with multiple small transport blocks, TBoMS can reduce header overhead, achieve channel coding gain, and improve decoding performance and transmission rate.

During the communication process, some signal transmission resources may conflict, that is, resources overlap. When the terminal device does not have the ability to send these signals at the same time, some rules can be defined, such as which signals are sent preferentially when overlapping occurs, so as to ensure that the understanding of the network device and the terminal device is consistent, so that the communication can proceed normally.

Existing rules for resource overlap apply only to small transport blocks on a single slot, not TBoMS. Therefore, when a terminal device uses TBoMS for uplink transmission, how to deal with resource overlap becomes an urgent problem to be solved.

Detailed ways

Before describing the embodiments of the present application, technical terms involved in the embodiments of the present application will be described.

High-level signaling: may refer to signaling sent by a high-level protocol layer. The high-level protocol layer may be at least one protocol layer above the physical layer. Wherein, the high-level protocol layer may specifically include at least one of the following protocol layers: medium access control (medium access control, MAC) layer, radio link control (radio link control, RLC) layer, packet data convergence protocol (packet data convergence) protocol, PDCP) layer, radio resource control (radio resource control, RRC) layer and non-access stratum (non access stratum, NAS).

Multi-slot transport block (transport block over multi-slot, TBoMS): includes transport block (transport block, TB) on multiple time slots.

In the uplink transmission process of the communication system, limited by the transmission capability of the terminal equipment, such as: fewer antennas, general baseband chip processing, limited uplink transmission power and other constraints, compared with downlink transmission, the transmission performance of uplink transmission Faced with greater challenges, especially in long-distance and deep fading scenarios, the uplink transmission performance of terminal equipment will deteriorate sharply. In some deep coverage scenarios, such as cell edges or basements, the path loss of wireless signal propagation is relatively serious. In order to improve uplink transmission performance, the communication system proposes that TBoMS can be used for uplink transmission.

Among them, as shown in Figure 1, the terminal device can calculate the transport block set (transport block set, TBS) based on the resources on multiple time slots, and map to multiple time slots for transmission, that is, the TB on multiple time slots aggregated into a TBoMS for transmission. Compared with multiple small transport blocks, it can reduce the packet header overhead, realize the channel coding gain of channel coding after multiple small transport blocks are aggregated into TBoMS, and improve the decoding performance and transmission rate of uplink transmission.

During the communication process, there may be conflicts in the sending resources of some signals, that is, resource overlap. When the terminal device does not have the ability to send these signals at the same time, some rules can be defined, such as which signals are sent preferentially when overlapping occurs. In order to ensure that the understanding of network equipment and terminal equipment is consistent, to ensure the normal progress of communication.

Exemplarily, taking a terminal device sending a physical uplink shared channel (PUSCH) as an example, when the sending resource of the PUSCH overlaps with any of the following resources, the transmission of the PUSCH can be canceled: when the semi-statically configured downlink slots or symbols, time-domain resources occupied by repeated physical uplink control channels (PUCCH), time-domain resources occupied by PUCCHs with higher priority than PUSCH, semi-static configuration on reference cells or other cells in carrier aggregation downlink time slot or symbol.

When a terminal device uses TBoMS for uplink transmission, TBoMS corresponding to multiple time slots can be used as a physical uplink shared channel (PUSCH). When the transmission of PUSCH is canceled due to resource overlap, it will cause TBoMS If canceled, uplink resources are wasted and uplink coverage is affected.

For example, as shown in Figure 2, taking TBoMS corresponding to four time slots as an example, assuming that resource overlap occurs only in the second time slot, it is necessary to cancel the transmission of the entire TBoMS, that is, to cancel TBoMS on the four time slots, resulting in uplink resources being blocked. waste.

In another example, taking the PUSCH sent by the terminal device as an example, when the semi-statically configured PUSCH overlaps with the downlink symbols dynamically indicated by downlink control information (DCI), when the terminal device does not support partial cancellation, If the start symbol of the PUSCH is within T _proc,2 time after the last symbol of the DCI, the PUSCH transmission is not canceled; otherwise, the PUSCH transmission is cancelled. When the terminal device supports partial cancellation, it can only cancel the PUSCH transmission after the T _proc,2 time after the last symbol of the DCI, and the previous ones may not be canceled.

Among them, the semi-statically configured PUSCH can have two scheduling methods. The first is grant based (GB) scheduling. In this method, the scheduling network device can send a physical downlink control channel (physical downlink control channel) to the terminal device. , PDCCH), the PDCCH can schedule the PUSCH transmission of uplink data, that is, the PDCCH can indicate (physical downlink shared channel, PDSCH) or PUSCH time domain resources. The second is to configure grant scheduling, which can include two types, configured grant type 1 (configured grant type 1) and configured grant type 2 (configured grant type 2), among them, the scheduling mode of configured grant type 2 and the first A scheduling method is similar, that is, the network device sends PDCCH activation configuration scheduling to the terminal device, and the terminal device then sends PUSCH according to the high-level configuration information; for configuration authorization type 1, the network device will not send PDCCH to the terminal device, and the PUSCH transmission occupies The location of the time-domain resource may be configured through high-layer signaling.

Wherein, T _proc,2 =max((N ₂ +d _2,1 +d ₂ )(2048+144)·κ2 ^−μ ·T _c +T _ext +T _switch ,d _2,2 ).

Wherein, _N2 is the PUSCH preparation time based on μ respectively determined according to the PUSCH preparation time under PUSCH timing capability 1 shown in Table 1 below and the PUSCH preparation time under PUSCH timing capability 2 shown in Table 2 below. μ can correspond to one of (μDL, μUL), the value of μ can satisfy T _{proc, and 2} takes the maximum value. μDL corresponds to the subcarrier spacing of the PDCCH that schedules the PUSCH, and μUL corresponds to the subcarrier spacing of the uplink channel that transmits the PUSCH. If the first symbol of the PUSCH only contains a demodulation reference signal (demodulation reference signal, DM-RS), then d _2,1 =0, otherwise d _2,1 =1. If the resources of the high-priority PUSCH and the low-priority PUCCH overlap, d ₂ of the high-priority PUSCH can be set through the value reported by the terminal device, otherwise d ₂ =0. Kappa is equal to 64. T _c may be equal to 1/(480*10^3*4096), and the unit of T _c may be seconds (s). For the processing of non-shared spectrum channel access, T _ext =0. T _switch represents the switching time. If the scheduled DCI triggers a bandwidth part (BWP) switch, d _2,2 is equal to the switch time, otherwise d _2,2 =0.

When a terminal device uses TBoMS for uplink transmission, TBoMS corresponding to multiple time slots can be used as a PUSCH. When the transmission of PUSCH is canceled due to resource overlap, when the terminal device does not support partial cancellation, if the TBoMS start symbol Within T _proc,2 time after the last symbol of the DCI, the TBoMS transmission may not be canceled; otherwise, the TBoMS transmission is cancelled. When the terminal device supports partial cancellation, it can only cancel the TBoMS transmission after T _proc,2 time after the last symbol of the DCI, and the previous ones may not be canceled. When TBoMS is canceled, uplink resources will be wasted and uplink coverage will be affected.

For example, as shown in Figure 3, taking TBoMS corresponding to four time slots as an example, assuming that resource overlap occurs only in the second time slot, when the terminal device does not support partial cancellation, if the start symbol of TBoMS is after the last symbol of DCI The TBoMS transmission may not be canceled within the T _proc,2 time, otherwise, if the TBoMS start symbol is outside the T _proc,2 time after the last DCI symbol, the TBoMS transmission is cancelled. When the terminal device supports partial cancellation, it can only cancel TBoMS transmission after T _{proc, 2} time after the last symbol of DCI, and the previous ones can not be canceled. For example, TBoMS can be canceled from the second half of the second time slot Transfer, previous ones are not cancelled. When TBoMS is canceled, uplink resources will be wasted and uplink coverage will be affected.

In another example, taking the PUSCH sent by the terminal device as an example, when the time domain resources occupied by the PUSCH include the time domain resources indicated by the network device to cancel the PUSCH transmission, the terminal device cancels the time domain resources occupied by the PUSCH first PUSCH transmission following the symbol indicating cancellation of PUSCH transmission.

Wherein, the network device may send cancellation indication information (cancellation indication) to the terminal device, in which cancellation indication information may indicate through a bitmap, which time domain resource positions in a certain time domain resource the PUSCH of which time domain resource positions are to be canceled, and may be passed Setting a bit to 1 indicates that the time domain position corresponding to this bit cancels PUSCH transmission. If at least one symbol in the time domain resources occupied by the PUSCH is indicated as 1, starting from the first symbol indicated as 1 in the time domain resources occupied by the PUSCH, all subsequent PUSCH transmissions are cancelled.

For example, taking symbol 2 to symbol 12 that PUSCH occupies a certain time slot as an example, assuming that symbol 3 and symbol 4 are indicated as 1, symbol 2 reserves PUSCH transmission, and all PUSCH transmissions from symbol 3 to symbol 12 are cancelled.

When a terminal device uses TBoMS for uplink transmission, TBoMS corresponding to multiple time slots can be used as a PUSCH. When canceling the time domain resource for transmission, the terminal device may cancel the TBoMS transmission after the first symbol indicated to cancel the transmission in the time domain resource occupied by the TBoMS. Since the TBoMS occupies multiple time slots, when the terminal equipment cancels the TBoMS transmission, uplink resources will be wasted and uplink coverage will be affected.

For example, as shown in Figure 4, taking TBoMS corresponding to four time slots as an example, assuming that only the second time slot includes the time domain resource indicated by the network device for which transmission is canceled, and the time domain resource for which transmission is canceled indicated by the network device Indicates that the last symbol in is 1, then the terminal device can cancel the TBoMS transmission of the last symbol and after the last symbol, resulting in waste of uplink resources and affecting uplink coverage.

To sum up, when a terminal device uses TBoMS for uplink transmission, how to deal with resource overlap, improve resource utilization, and improve uplink coverage has become an urgent problem to be solved.

Based on the above problems, an embodiment of the present application provides a data transmission method, which may include: a terminal device acquires information about time domain resources occupied by a multi-slot transmission block TBoMS, and when the time domain resources occupied by TBoMS are the same as the first time domain resource When resource overlap occurs, the terminal device cancels the transmission of the TBoMS on the second time domain resource or the third time domain resource; wherein, the second time domain resource is part of the time domain resources occupied by the TBoMS, and the third time domain resource The resource is a time domain resource in which the time domain resource occupied by the TBoMS overlaps with the first time domain resource, and the third time domain resource is a part of the second time domain resource.

In the embodiment of the present application, when the time domain resource occupied by TBoMS overlaps with the first time domain resource, the terminal device can make the communication proceed normally by canceling the transmission of TBoMS on the second time domain resource or the third time domain resource . In addition, cancellation of the entire TBoMS can be avoided, thereby improving resource utilization and uplink coverage.

For example, if the table sent by the network device to the terminal device includes 16 rows, and as an example to indicate 16 time-domain resources respectively, 4 bits can be used as the row index to indicate the 16 time-domain resources, that is, the row indexes can be 0000 and 0001 respectively , ..., 1111, assuming that the network device carries the row index 0000 in the third indication information and sends it to the terminal device, the terminal device can determine that the symbol position occupied by TBoMS in each time slot is the first in the table according to the third indication information The time domain resource location indicated by the row.

Optionally, each row of the table further includes fourth indication information.

Wherein, 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.

Exemplarily, taking the start symbol included in the row indicated by the row index as 2, the number of symbols as 12, and the number of time slots occupied by TBoMS as 4, as shown in FIG. 8, the symbol of each time slot can be determined 2 to 13 are time domain resources occupied by TBoMS.

It should be noted that the network device may carry the row index in the third indication information and send it 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 high-layer signaling and send it to the terminal device, so that the terminal device determines the fourth indication information according to the high-layer signaling.

Optionally, the network device may also send fifth indication information to the terminal device.

Wherein, the fifth indication information is used to indicate the position of the starting time slot of the TBoMS.

Exemplarily, the network device may determine the position of the starting time 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 time slot after the last symbol of the received DCI as the starting time slot of TBoMS, that is, the fifth indication information is used to indicate the Nth time slot after the last symbol of the DCI time slot.

It should be noted that the network device may carry the fifth indication information in the third indication information and send it to the terminal device, or carry the fifth indication information in high-level signaling and send it to the terminal device, without limitation.

Optionally, the terminal device also receives sixth indication information sent by the network device.

Wherein, the sixth indication information may be used to instruct the terminal device to perform uplink transmission in TBoMS mode, and the terminal device may determine time domain resources occupied by TBoMS based on the sixth indication information and perform uplink transmission in TBoMS mode.

Step 702: When the time domain resource occupied by the TBoMS overlaps with the first time domain resource, the terminal device cancels the transmission of the TBoMS on the second time domain resource or the third time domain resource.

Wherein, the first time domain resource may be any of the following time domain resources: semi-statically configured downlink time slots or symbols, time domain resources occupied by repeated PUCCHs, time domain resources occupied by PUCCHs with priority higher than TBoMS, carrier aggregation The reference cell or semi-statically configured downlink time slots or symbols on other cells.

Wherein, the second time domain resource may be a part of the time domain resources occupied by the TBoMS, the third time domain resource may be a time domain resource in which the time domain resource occupied by the TBoMS overlaps with the first time domain resource, and the first time domain resource The three time domain resources may be part of the second time domain resources.

Specifically, the time domain resources occupied by the TBoMS may be divided into multiple second time domain resources, and it is determined whether each second time domain resource includes a time domain in which the time domain resources occupied by the TBoMS overlap with the first time domain resources resources, if included, cancel the transmission of TBoMS on the second time domain resource, or cancel the transmission of TBoMS on the third time domain resource in the second time domain resource, otherwise, normal Transmit TBoMS.

It should be noted that when the time domain resources occupied by the TBoMS overlap with the first time domain resource and occupy the entire second time domain resource, the third time domain resource may also be described as the second time domain resource.

Exemplarily, the second time domain resource may be one or more of the following: one or more time slots, one or more symbols, a time domain resource occupied by TBoMS in a time slot, and a transmission opportunity (time domain occasion of TBoMS, the time domain resource occupied by TOT).

Wherein, the terminal device may determine the time-domain resource occupied by the TBoMS in one time slot according to the above-mentioned start symbol and the number of symbols.

Wherein, the time-domain resources occupied by TOT can be any of the following time-domain resources: time-domain resources occupied by a redundant version of TBoMS, time-domain resources corresponding to a time granularity for bit selection and bit interleaving in TBoMS, and TBoMS performance rate Match the time domain resource corresponding to the time unit.

Wherein, the time domain resource occupied by the TOT may be pre-configured by high-level signaling, or may be indicated by high-level signaling, or may be determined by the terminal device according to a certain rule.

Exemplarily, the certain rule may be: adopt the TOT stipulated in the communication protocol. 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 is specifically which of the above time domain resources may be pre-agreed by the communication protocol, or configured by the network device through high-level signaling. be restricted.

In addition, when the time domain resource occupied by the TBoMS overlaps with the first time domain resource, the terminal device can 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 second time domain resource according to the pre-agreement of the communication protocol. TBoMS transmission on the third time domain resource. Alternatively, the terminal device may also determine to cancel the transmission of the TBoMS on the second time domain resource according to the preconfiguration of the network device, or cancel the transmission of the TBoMS on the third time domain resource according to the preconfiguration of the network device.

Optionally, when the terminal device supports partial cancellation, the terminal device cancels the transmission of the TBoMS on the second time domain resource or the third time domain resource. When the terminal equipment does not support partial cancellation, the terminal equipment cancels the transmission of TBoMS.

Wherein, 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. Alternatively, the terminal device may also receive second indication information from the network device; the second indication information is used to indicate whether the terminal device 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.

Exemplarily, the terminal device sends to the network device first indication information for indicating that the terminal device supports partial cancellation. The device sends second indication information for indicating that the terminal device does not support partial cancellation, and after receiving the second indication information, the terminal device cancels the TBoMS transmission when resource overlap occurs according to the second indication information.

Based on the above steps 701 and 702, step 702 will be described in detail with reference to the following four examples.

In the 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 TBoMS overlaps with the semi-statically configured downlink time slot or symbol, the terminal device can Cancel the transmission of the TBoMS on the second time domain resource or the third time domain resource.

Among them, the network device can configure the frame structure for the terminal device by sending high-level signaling to the terminal device, that is, which time slots or symbols are configured as downlink, which time slots or symbols are configured as uplink, and which time slots or symbols are configured as flexible. A time slot or symbol configured as downlink can only transmit downlink signals, a time slot or symbol configured as uplink can only transmit uplink signals, and a symbol configured as flexible can sometimes transmit uplink signals, and sometimes can transmit downlink signals.

Wherein, the high-level signaling may be cell-level uplink and downlink time slot configuration (tdd-UL-DL-configuration common) and UE-specific uplink and downlink time slot configuration (tdd-UL-DL-configuration dedicated).

Exemplarily, 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 as an example, assuming that the TBoMS occupies four time slots , the second time domain resource is the time domain resource occupied by TOT, and the time domain resource occupied by each TOT includes two time slots, as shown in (a) in Figure 9, when the semi-statically configured downlink time slot or symbol When resource overlap occurs in the second time slot with the time domain resource occupied by TBoMS, the terminal device can cancel the transmission of TBoMS on the first TOT and keep the transmission of TBoMS on the second TOT, that is, the terminal device cancels the transmission of TBoMS on the first TOT. The transmission of TBoMS on the first and second time slots, and the transmission of TBoMS on the third and fourth time slots are reserved.

In another example, 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 third time domain resource as an example, assuming that the TBoMS occupies four time slot, the second time domain resource is the time domain resource occupied by TOT, and the time domain resource occupied by each TOT includes two time slots, as shown in (b) in Figure 9, when the semi-statically configured downlink time slot Or when the time domain resources occupied by symbols and TBoMS overlap in the second time slot, the terminal device can cancel the transmission of TBoMS on the third time domain resource and reserve the transmission of TBoMS on other time domain resources of TBoMS, that is, the terminal The device cancels the TBoMS transmission on the time-domain resources with overlapping resources in the second time slot, and reserves the first time slot, the time-domain resources without overlapping resources in the second time slot, the third time slot, and the time-domain resources in the second time slot. Transmission of TBoMS on four time slots.

In another possible design, as shown in (c) in Figure 9, the terminal device may also cancel the transmission of the TBoMS on the time slot where the third time domain resource is located, that is, the terminal device cancels the transmission of the TBoMS on the second time slot. For the transmission of TBoMS, the transmission of TBoMS on the first time slot, the third time slot and the fourth time slot is reserved.

In the second example, taking the first time domain resource as an example occupied by a repeated PUCCH, when the time domain resource occupied by TBoMS overlaps with the time domain resource occupied by a repeated PUCCH, the terminal device can cancel the time domain resource occupied by the repeated PUCCH. TBoMS transmission on the second time domain resource or the third time domain resource.

Exemplarily, when the time domain resource occupied by the TBoMS overlaps with the time domain resource occupied by the repeated PUCCH, the terminal device cancels the transmission of the TBoMS on the second time domain resource as an example, assuming that the TBoMS occupies six time slots, The second time domain resource is the time domain resource occupied by the TOT, and the time domain resource occupied by each TOT includes two time slots, as shown in (a) in Figure 10, when the time domain resource occupied by the repeated PUCCH is the same as that of the TBoMS When the occupied time domain resource overlaps in the first time slot and the third time slot, the terminal device can cancel the transmission of TBoMS on the first TOT and the second TOT, and retain the TBoMS on the third TOT The transmission of TBoMS, that is, the terminal equipment cancels the transmission of TBoMS on the first time slot, the second time slot, the third time slot and the fourth time slot, and reserves the transmission of TBoMS on the fifth and sixth time slots. Transmission of TBoMS.

In another example, when the time domain resource occupied by the TBoMS overlaps with the time domain resource occupied by the repeated PUCCH, the terminal device cancels the transmission of the TBoMS on the third time domain resource as an example, assuming that the TBoMS occupies six hours The second time domain resource is the time domain resource occupied by TOT, and the time domain resource occupied by each TOT includes two time slots, as shown in (b) in Figure 10, when the time domain resource occupied by the repeated PUCCH When resources overlap with the time domain resource occupied by TBoMS in the second time slot, the terminal device can cancel the transmission of TBoMS on the third time domain resource and reserve the transmission of TBoMS on other time domain resources of TBoMS, that is, the terminal device cancels The transmission of TBoMS on the time-domain resources with overlapping resources in the first and third time slots, reserve the time-domain resources without overlapping resources in the first and third time slots, and the second The transmission of TBoMS on the first time slot, the fourth time slot, the fifth time slot and the sixth time slot.

In another possible design, as shown in (c) in Figure 10, 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 first time slot and the second time slot. For the transmission of TBoMS on three time slots, the transmission of TBoMS on the second, fourth, fifth and sixth time slots is reserved.

In the third example, taking the first time domain resource as the time domain resource occupied by PUCCH with higher priority than TBoMS as an example, when the time domain resource occupied by TBoMS and the time domain resource occupied by PUCCH with higher priority than TBoMS When overlapping, the terminal device may cancel the transmission of the TBoMS on the second time domain resource or the third time domain resource.

Wherein, the priority of the PUCCH may be indicated by the DCI for scheduling the PDSCH, or may be configured by high-level 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 can be indicated by the DCI or configured by high-layer signaling.

Exemplarily, when the time domain resource occupied by TBoMS overlaps with the time domain resource occupied by PUCCH with higher priority than TBoMS, the terminal device cancels the transmission of TBoMS on the second time domain resource as an example, assuming that TBoMS occupies four time slots, the second time domain resource is the time domain resource occupied by TOT, and the time domain resource occupied by each TOT includes two time slots, as shown in (a) in Figure 11, when the priority is higher than that of TBoMS When the time domain resources occupied by PUCCH and the time domain resources occupied by TBoMS overlap in the third time slot, the terminal device can cancel the transmission of TBoMS on the second TOT and retain the transmission of TBoMS on the first TOT. That is, the terminal equipment cancels the transmission of the TBoMS on the third time slot and the fourth time slot, and reserves the transmission of the TBoMS on the first time slot and the second time slot.

In another example, when the time domain resource occupied by TBoMS overlaps with the time domain resource occupied by PUCCH with a higher priority than TBoMS, the terminal device cancels the transmission of TBoMS on the third time domain resource as an example, assuming that TBoMS Occupy four time slots, the second time domain resource is the time domain resource occupied by TOT, and the time domain resource occupied by each TOT includes two time slots, as shown in (b) in Figure 11, when the priority is higher than When the time domain resource occupied by the PUCCH of TBoMS and the time domain resource occupied by TBoMS overlap in the third time slot, the terminal device can cancel the transmission of TBoMS on the third time domain resource and reserve the transmission of TBoMS on other time domain resources. TBoMS transmission, that is, the terminal device cancels the TBoMS transmission on the time domain resources where resource overlap occurs in the third time slot, and reserves the first time slot, the second time slot, and the third time slot without resource overlap The time domain resources of , and the transmission of TBoMS on the fourth time slot.

In another possible design, as shown in (c) in Figure 11, 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 third time slot. For the transmission of TBoMS, the transmission of TBoMS on the first time slot, the second time slot, and the fourth time slot is reserved.

In the fourth example, taking the first time domain resource as an example of a semi-statically configured downlink time slot or symbol on the reference cell or other cells in carrier aggregation, when the time domain resource occupied by TBoMS is the same as that on the reference cell or When resource overlap occurs in downlink time slots or symbols configured semi-statically on other cells, the terminal device may cancel TBoMS transmission on the second time domain resource or the third time domain resource.

Among them, if the terminal device is configured with multiple cells, and the half-duplex behavior is equal to enabling (half-duplex-behavior='enable'), it indicates that half-duplex conflict processing is required, and the terminal device has no ability to The cell supports simultaneous transmission and reception, and the terminal device reports that the network device can support half-duplex operation, and the blind detection DCI format 2_0 is not configured, then when the following symbols overlap with the time domain resources occupied by TBoMS, the terminal device can cancel the second time domain Transmission of TBoMS on domain resources or third time domain resources:

1. If this symbol is used in any serving cell by the ssb-positions in burst field in the system information block 1 (SIB1) signaling or the ssb in the serving cell config common signaling The -positions in burst field is indicated as a symbol for receiving a synchronization/broadcast data (sync signal/physical broadcast channel, SS/PBCH) block.

2. If the symbol is indicated as downlink by cell-level uplink and downlink time slot configuration or UE-specific uplink and downlink time slot configuration parameters in the reference cell, or is configured to receive PDCCH, PDSCH, or channel state information reference signal by high-layer signaling (channel state information-reference signal, CSI-RS) symbol.

Exemplarily, when the time domain resource occupied by the TBoMS overlaps with the semi-statically configured downlink time slot or symbol on the reference cell or other cells in the carrier aggregation, the terminal device cancels the transmission of the TBoMS on the second time domain resource For example, assume that TBoMS occupies four time slots, the second time domain resource is the time domain resource occupied by TOT, and the time domain resource occupied by each TOT includes two time slots, as shown in (a) in Figure 12, When the downlink time slots or symbols configured semi-statically on the reference cell or other cells in carrier aggregation overlap with the time domain resources occupied by TBoMS in the second time slot, the terminal device can cancel the TBoMS on the first TOT The transmission of TBoMS on the second TOT is reserved, that is, the terminal equipment cancels the transmission of TBoMS on the first and second time slots, and reserves the TBoMS on the third and fourth time slots transmission.

In another example, when the time domain resource occupied by TBoMS overlaps with the semi-statically configured downlink time slot or symbol on the reference cell or other cells in carrier aggregation, the terminal device cancels the TBoMS on the third time domain resource As an example, assume that TBoMS occupies four time slots, the second time domain resource is the time domain resource occupied by TOT, and the time domain resource occupied by each TOT includes two time slots, as shown in (b) in Figure 12 It shows that when the downlink time slots or symbols configured semi-statically on the reference cell or other cells overlap with the time domain resources occupied by TBoMS in the second time slot, the terminal device can cancel the third time domain resource The transmission of TBoMS on TBoMS, and the transmission of TBoMS on other time domain resources of TBoMS, that is, the terminal equipment cancels the transmission of TBoMS on time domain resources where resource overlap occurs in the second time slot, and reserves the first time slot, the second In the first time slot, there is no resource overlap in the time domain resource, and the transmission of TBoMS in the third time slot and the fourth time slot.

In another possible design, as shown in (c) in Figure 12, 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. For the transmission of TBoMS, the transmission of TBoMS on the first time slot, the third time slot and the fourth time slot is reserved.

Based on the method shown in Figure 7 above, when the time domain resource occupied by TBoMS overlaps with the first time domain resource, the terminal device can cancel the transmission of TBoMS on the second time domain resource or the third time domain resource, so that Communication proceeds normally. In addition, cancellation of the entire TBoMS can be avoided, thereby improving resource utilization and uplink coverage.

FIG. 13 is a flow chart of a data transmission method provided in the embodiment of the present application. As shown in FIG. 13, the method may include:

Step 1301, the network device acquires information about time domain resources occupied by the TBoMS.

For the description of the time domain resource information occupied by the TBoMS, reference may be made to the relevant description in the above step 701, and details are not repeated here.

Step 1302: 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.

Wherein, for the description of the first time domain resource, the second time domain resource, and the third time domain resource, reference may be made to the relevant description in step 702 above, and details are not repeated here.

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 device determines that the terminal device does not support partial cancellation, the network device does not receive TBoMS.

Wherein, the network device may receive first indication information from the terminal device; the first indication information may be used to indicate whether the terminal device supports partial cancellation. Alternatively, the network device may determine whether the terminal device supports partial cancellation, 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.

Wherein, for the description of the first indication information and the second indication information, reference may be made to the relevant description in the above step 702, and details are not repeated here.

Based on the method shown in Figure 13, when the time domain resource occupied by the TBoMS overlaps with the first time domain resource, the terminal device may cancel the transmission of the TBoMS on the second time domain resource or the third time domain resource, correspondingly, The network device may not receive the TBoMS in the second time domain resource or the third time domain resource, so that communication can be performed normally. In addition, cancellation of the entire TBoMS can be avoided, thereby improving resource utilization and uplink coverage.

Different from the first time domain resources shown in Figure 7 to Figure 13 above, as shown in Figure 14, when the time domain resources occupied by the TBoMS overlap with the time domain resources indicated by the DCI, the terminal device can refer to the following Figure 14 The shown method processes the transmission of TBoMS.

For the description of step 1401, reference may be made to the related description of step 701 above, and details are not repeated here.

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 send a PDCCH to carry a DCI format 2_0, and this DCI format may indicate that symbols in one or more time slots (that is, the fourth time domain resource) are uplink symbols or downlink symbols or flexible symbols. Or the DCI can schedule a PDSCH or a CSI-RS on some symbols (that is, the fourth time domain resource).

Step 1403: When the fourth time domain resource overlaps with the time domain resource occupied by 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 is equal to the first threshold, the terminal device cancels the transmission of the TBoMS on the second time domain resource.

Wherein, the second time domain resource is a part of the time domain resources occupied by the TBoMS, and the second time domain resource includes a time domain resource in which the resource overlaps between the fourth time domain resource and the time domain resource occupied by the TBoMS.

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 start symbol of the second time domain resource is smaller than the first threshold, the terminal device does not cancel the TBoMS on the second time domain resource transmission.

Exemplarily, 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 start symbol of the second time domain resource is smaller than the first threshold, the terminal device may not cancel the TBoMS Transmission, that is, the terminal equipment reserves the transmission of TBoMS on the first time slot, the second time slot, the third time slot and the fourth time slot.

Step 1404: When the fourth time domain resource overlaps with the time domain resource occupied by the TBoMS, if the terminal device supports partial cancellation, the terminal device cancels the transmission of the TBoMS after the first symbol in the second time domain resource.

Wherein, the distance between the first symbol and the last symbol of the DCI may be the first threshold.

Exemplarily, as shown in FIG. 17 , taking TBoMS occupying four time slots and the second time domain resource being one time slot as an example, when the fourth time domain resource and the time domain resource occupied by TBoMS are on the second time slot When resource overlap occurs, assuming that the terminal device supports partial cancellation, the terminal device cancels the transmission of the TBoMS after the first symbol in the second time domain resource where the resource overlap occurs, or it is described as the terminal device cancels the transmission in the second time domain resource where the resource overlap occurs Transmission of TBoMS after the first threshold time after the last symbol of the DCI. That is, the terminal device cancels the transmission of the TBoMS after the first threshold time after the last symbol of the DCI in the second time slot.

In step 1403 and step 1404 above, 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 can process the transmission of the TBoMS based on the above method, so that communication can proceed normally. In addition, cancellation of the entire TBoMS can be avoided, thereby improving resource utilization and uplink coverage.

In Figure 14 above, when the time domain resource occupied by TBoMS overlaps with the fourth time domain resource, the terminal device processes the transmission of TBoMS, as shown in Figure 18, when the time domain resource occupied by TBoMS and the fourth time domain resource overlap When resource overlap occurs in the fourth time domain resource, the network device may process TBoMS transmission referring to the method shown in FIG. 18 .

Wherein, the second time domain resource is a part of the time domain resources occupied by the TBoMS, and the second time domain resource includes a time domain resource in which the resource overlaps between the fourth time domain resource and the time domain resource occupied by the TBoMS.

For the description of the second time-domain resource and the first threshold, reference may be made to the related description of step 1403 above, and details are not repeated here.

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.

Wherein, the distance between the first symbol and the last symbol of the DCI is the first threshold.

Wherein, for the description of the first symbol, reference may be made to the relevant description of the above-mentioned step 1404, and details are not repeated here.

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 can process the transmission of the TBoMS based on the above method, so that communication can proceed normally. In addition, cancellation of the entire TBoMS can be avoided, thereby improving resource utilization and uplink coverage.

Different from the first time domain resource and the fourth time domain resource shown in FIG. 7 to FIG. 18 above, as shown in FIG. 19 , when the time domain resources occupied by the TBoMS include the time domain resources indicated by the DCI for which the transmission of the TBoMS is canceled , the terminal device may refer to the method shown in FIG. 19 below to process the TBoMS transmission.

Wherein, for the description of step 1901, reference may be made to the relevant description of the above-mentioned step 701, and details are not repeated here.

Step 1902, the terminal device receives the DCI from the network device.

Wherein, the DCI may be used to indicate the time-domain resource of the canceled TBoMS transmission.

Exemplarily, the network device may use a bitmap to indicate the time-domain resources for which TBoMS transmission is canceled, for example, a bit may be set to 1 to indicate that the symbol corresponding to the bit is canceled for TBoMS transmission.

Step 1903: When the second time domain resource includes the time domain resource indicated by the DCI for which TBoMS transmission is canceled, the terminal device cancels the TBoMS transmission after the second symbol in the second time domain resource.
