Technical Field

The application belongs to the technical field of communication, and particularly relates to an interrupt transmission indication method, a cancel indication method, a terminal and network side equipment.

Background

Future 5G mobile communication systems need to accommodate more diverse scenarios and service requirements than previous mobile communication systems. The main scenarios of 5G include enhanced mobile bandwidth (Enhanced Mobile Broadband, eMBB), ultra-reliable and low latency communications (Ultra-Reliable and Low Latency Communications, URLLC), large-scale machine communications (Massive Machine Type Communication, mctc), which place high reliability, low latency, large bandwidth, wide coverage, etc. requirements on the system.

The current network introduces a downlink interrupt transmission indication (Interrupted transmission indication, INT) indicating which transmission resources a certain terminal was before do not belong to the user's schedule for transmission of suddenly arriving higher priority traffic. The network transmits the downlink INT, and if the allocated resources of the terminal which is scheduled previously fall in the time-frequency area acted by the downlink INT, the terminal will exclude the part of the time-frequency resources and decode.

The current network also introduces an uplink cancellation indication (Cancellation Indication, CI), i.e. the network can instruct some terminals to cancel traffic that has been scheduled for transmission of suddenly arriving higher priority traffic. The network sends an uplink CI and if the allocated resources of the previously scheduled terminal fall within the time-frequency region indicated by the uplink CI, the terminal will cancel the previously scheduled transmission.

In the prior art, full duplex operation is introduced, and for an uplink symbol indicated by a cell-level uplink and downlink configuration (TDD-UL-DL-configuration Common), a downlink sub-band may be included; alternatively, the downlink symbol indicated by the TDD-UL-DL-configurationcommand signaling may include an uplink subband. In this scenario, the existing time-frequency resource indication mode of downlink INT or uplink CI is no longer applicable.

In the case where the downlink INT is a 14-bit bitmap and the second symbol set includes 7 symbol groups, M is equal to 2, and the first PRB set includes: front of the symbol groupThe second set of PRBs includes: the symbol group is back->Each PRB;

In order to more clearly describe the interrupt transmission indication method in the full duplex scenario provided in the embodiment of the present application, the following description is made with reference to an example.

Example 1

An example of the INT indication in full duplex is shown in FIG. 6. Corresponding to one subcarrier spacing SCS u, for time slot n (slot n), the network is configured as DL slot, for time slot n+1 (slot n+1), the network is configured as UL slot, e.g. configured by TDD-UL-DL-configuration command signaling.

Further, the network is configured with UL subbands on slot n and DL subbands on slot n+1. For UL subbands on DL slots of the network configuration, PRBs of UL subbands of the DL slots may be excluded when indicated using INT. The DL subband in the UL slot of the network configuration should be included in the INT indication, i.e. this part of the symbol should not be excluded.

As shown in fig. 7, the following diagram gives an example of the operation of a full duplex scenario INT, where the TDD configuration of the network by the configuration parameter TDD-UL-DL-configuration command is 13 DL symbols 1 UL symbol in both slots. UL subbands are arranged on DL symbols on slot n, and DL subbands are arranged on UL symbols on slot n and slot n+1.

Since DL subbands are included in UL symbols, UL symbols should not be excluded at the time of symbol grouping.

For PRB determination, PRBs that fall entirely on the UL subband may be excluded for a certain symbol group, since these PRBs are not indicated to be cancelled by the INT. This may be a finer granularity of indication, and in fact, a granularity of indication is determined per symbol group.

For example, the symbol group acted upon by INT, when timeFrequencySet is set to 'set1', assumes that 28 symbols are divided into 7 symbol groups, each group containing 4 symbols.

For the 1 st symbol group, the 2 nd symbol group, the 3 rd symbol group, due to being configured with UL subbands, has a PRB subset on 4 symbols and UL subband B _{int_UL subband 1} The PRBs used for UL transmission are not indicated to cancel by the INT when the PRBs contained in one bit pair should be excluded when calculating them, i.e. PRBs with valid DL subbands, i.e. B _{int_DL subband 1} Rather than the entire PRB activating DL BWP.

First bit before indication (first)The PRBs (i.e., the first PRB set);

the second bit indicates the last (last)The PRBs (i.e., the second PRB set).

For the 5 th symbol group and the 6 th symbol group, the entire PRB of the activated DL BWP, i.e., B, should be used _INT 。

First bit before indication (first) PRB (i.e., first PRB set);

the second bit indicates the last (last)PRBs (i.e., the second PRB set).

For the 4 th symbol group and the 7 th symbol group, both DL subbands of UL symbols and UL subbands of DL symbols are included. I.e. PRBs of a symbol group that have no PRB subset falling completely within the UL sub-band, span different DL and/or UL sub-bands. The PRB of the entire active DL BWP should be used.

Before the first bit indicatesThe PRBs (i.e., the first PRB set);

the second bit indicates the lastThe PRBs (i.e., the second PRB set).

If the allocated resources of the terminal which is scheduled before fall in the time-frequency region acted by the downlink INT, the terminal will exclude the part of the time-frequency resources and then decode the data channel.

As shown in fig. 8, the embodiment of the present application further provides a cancellation indication method, including:

step 801, a terminal receives an uplink cancellation instruction CI;

step 802, the terminal determines, according to the granularity of the time-frequency domain indication, a physical resource block PRB set included in each of a plurality of symbol groups included in the fourth symbol set acted by the uplink cancellation indication CI; the fourth symbol set is obtained after excluding downlink symbols which do not contain uplink subbands in the third symbol set;

Optionally, the terminal excludes downlink symbols which do not include uplink subbands in the third symbol set, and obtains a fourth symbol set with uplink cancellation indication CI function, where the third symbol set is indicated by a network; the fourth set of symbols does not exclude downlink symbols comprising uplink subbands;

in step 803, the terminal determines whether the uplink transmission corresponding to the PRB set on each symbol group is cancelled according to the indication of the uplink CI.

In other words, in the embodiment of the present application, for determining the fourth symbol set (equivalent to time-frequency resource) acting on the uplink CI, the downlink symbol is indicated by the cell-level uplink-downlink configuration (TDD-UL-DL-configuration command), but the downlink symbol is indicated by the semi-static signaling to include the uplink sub-band (i.e., UL sub-band), so that the terminal does not exclude the downlink symbol, but the terminal needs to exclude the downlink symbol that does not include the UL sub-band.

Optionally, the frequency domain region B of the uplink CI action _CI The RRC configuration is controlled by radio resources.

Optionally, the time domain region (i.e., the fourth symbol set) in which the uplink CI functions is configured by RRC, excluding the symbols that receive DL symbols and/or SSB. If the semi-static signaling indicates that UL subbands are included in DL symbols, these DL symbols are not excluded. The network may configure whether to exclude the symbols of SSBs of the UL subbands that are included.

Optionally, the time domain indication granularity G of the uplink CI action _CI Configured by RRC.

Optionally, the frequency domain indication granularity N of the uplink CI action _BI Is based on the number N of bits of the uplink CI _CI And time domain indication granularity G _CI Calculated.

In at least one embodiment of the present application, step 803 includes:

the terminal determines a plurality of symbol groups included in the fourth symbol set according to the time domain indication granularity of the high-level configuration;

the terminal determines the frequency domain resource granularity according to the time domain indication granularity and the bit number of the uplink CI;

and the terminal determines a physical resource block PRB set included in each symbol group according to the frequency domain indication granularity.

Optionally, the fourth symbol set includes a plurality of symbol groups divided as follows:

front faceThe symbol group comprises->A number of symbols;

the remainderThe symbol group comprises->A number of symbols;

wherein G is _CI Indicating time domain indication granularity, T _CI Representing the number of symbols contained in the fourth set of symbols;representing a downward rounding; />Representing an upward rounding.

As an alternative embodiment, the method further comprises:

the terminal receives configuration information sent by the network side device, where the configuration information is used to indicate whether the fourth symbol set excludes symbols that include a receiving synchronization signal of an uplink sub-band or a physical broadcast channel block SSB.

If the network configuration excludes the received SSB symbols including the uplink sub-band, step 802 includes: the terminal excludes the downlink symbols which do not contain the uplink sub-band in the third symbol set and the symbols which receive SSB (whether the uplink sub-band is contained or not), and a fourth symbol set with uplink CI function is obtained;

if the network configuration does not exclude symbols of the received SSB including uplink subbands, step 802 includes: and the terminal excludes the downlink symbols which do not contain the uplink sub-band in the third symbol set and the symbols which do not contain the uplink sub-band and receive SSB, so as to obtain a fourth symbol set with uplink CI function.

In other words, if the SSB symbols configure UL subbands, the time domain region T where CI is determined to function is _CI The network may configure whether to exclude the SSB symbol.

As an optional embodiment, the determining, by the terminal, a physical resource block PRB set included in each symbol group according to the frequency domain indication granularity includes:

for each symbol group, if one PRB subset is completely overlapped with one downlink sub-band, the terminal obtains an effective frequency domain area after excluding the PRB subset, and divides the effective frequency domain area of the symbol group into N _BI A plurality of frequency domain groups;

wherein, front partThe PRB groups contain: Each PRB; residual->The set of PRB groups comprises:each PRB;

wherein N is _BI Indicating granularity for the frequency domain; b (B) _{CI_UL subband} And the number of PRBs in the effective frequency domain area of the symbol group.

Without loss of generality, if the network configures multiple UL subbands in the frequency domain, B _{CI_UL subband} Then the sum of the bandwidths of the multiple uplink subbands.

Alternatively, the PRB subset is excluded in case all symbols of the PRB subset across the symbol group overlap completely with one downlink subband.

As another optional embodiment, the determining, by the terminal, a physical resource block PRB set included in each symbol group according to the frequency domain indication granularity includes:

for each symbol group, if no PRB subset is completely overlapped with one downlink sub-band, the terminal divides the frequency domain area of the uplink CI action indicated by the higher layer into N _BI A plurality of PRB groups;

wherein N is _BI Indicating granularity for the frequency domain, B _CI The number of PRBs of the frequency domain region acting for the uplink CI indicated by the higher layer.

In other words, for a certain symbol group (including uplink symbols for TDD-UL-DL-configuration command signaling, but semi-static signaling C indicates that the symbol contains DL subbands, or downlink symbols for TDD-UL-DL-configuration command signaling, but semi-static signaling D indicates that the symbol contains UL subbands), a PRB subset (all symbols across the symbol group) is excluded if it overlaps with one DL subband. Otherwise, if no PRB subset (all symbols across the symbol group) is fully overlapped with one DL subband for the symbol group, the PRB subset of the symbol group is not excluded, i.e. according to B _CI A frequency domain PRB group is calculated.

It should be noted that, the semi-static signaling C and D may be different signaling, or may be the same signaling; for example xdd-UL-DL-configuration command is semi-static signaling configured by the network for full duplex operating UEs, indicating which subbands in one UL symbol set or slot are used as DL and which subbands in one DL symbol set or slot are used as UL. The semi-static signaling is not limited to group common signaling or dynamic signaling without loss of generality.

Alternatively, the network may instruct one CI to act on UL symbols containing DL subbands only, or on DL symbols containing UL subbands, or on UL symbols not containing DL subbands; the present invention is not particularly limited herein.

In summary, in the embodiment of the present application, a new uplink CI indication method is provided for a full duplex scene, so that time-frequency resource indication of the uplink CI can be applied to the full duplex scene, and indication accuracy of the uplink CI is improved.

As shown in fig. 9, the embodiment of the present application further provides a cancellation indication method, including:

step 901, the network side device determines a fourth symbol set acted by an uplink cancellation indication CI, where the fourth symbol set is obtained after excluding downlink symbols in the third symbol set that do not include an uplink subband;

Step 902, the network side device divides the fourth symbol set into physical resource block PRB sets included in each symbol group of the plurality of symbol groups according to the time-frequency domain indication granularity;

in step 903, the network side device generates and sends an uplink CI according to whether the uplink transmission corresponding to the PRB set on each symbol group needs to be canceled.

In other words, in the embodiment of the present application, for determining the fourth symbol set (equivalent to time-frequency resource) acting on the uplink CI, the downlink symbol is indicated by the cell-level uplink-downlink configuration (TDD-UL-DL-configuration command), but the downlink symbol is indicated by the semi-static signaling to include the uplink sub-band (i.e., UL sub-band), so that the network side device does not exclude the downlink symbol, but the network side device needs to exclude the downlink symbol that does not include the UL sub-band.

In at least one embodiment of the present application, step 902 includes:

the network side equipment divides the fourth symbol set into a plurality of symbol groups according to the time domain indication granularity;

the network side equipment determines the frequency domain resource granularity according to the time domain indication granularity and the bit number of the uplink CI;

and the network side equipment determines a physical resource block PRB set included in each symbol group according to the frequency domain indication granularity.

front faceThe symbol group comprises->A number of symbols;

the remainderThe symbol group comprises->A number of symbols;

As an alternative embodiment, the method further comprises:

the network side device sends configuration information to the terminal, where the configuration information is used to indicate whether the fourth symbol set excludes symbols that include a receiving synchronization signal of an uplink sub-band or a physical broadcast channel block SSB.

As an optional embodiment, the determining, by the network side device, the physical resource block PRB set included in each symbol group according to the frequency domain indication granularity includes:

for each symbol group, if one PRB subset is completely overlapped with one downlink subband, the network side device obtains an effective frequency domain area after excluding the PRB subset, and divides the effective frequency domain area of the symbol group into N _BI A plurality of frequency domain groups;

wherein, front part The PRB groups contain:each PRB; residual->The set of PRB groups comprises:each PRB;

As another optional embodiment, the determining, by the network side device, a physical resource block PRB set included in each symbol group according to the frequency domain indication granularity includes:

for each symbol group, if no PRB subset is completely overlapped with one downlink subband, the network side device divides the frequency domain region of the uplink CI action indicated by the higher layer into N _BI A plurality of PRB groups;

In other words, for a certain symbol group (including for TDD-UL-DL-configuration Common signaling indication as uplinkThe symbol, but semi-static signaling C indicates that the symbol contains a DL subband, or for TDD-UL-DL-configurationcommand signaling is indicated as a downlink symbol, but semi-static signaling D indicates that the symbol contains a UL subband), if a subset of PRBs (all symbols across the symbol group) overlaps with one DL subband, this subset of PRBs is excluded. Otherwise, if no PRB subset (all symbols across the symbol group) is fully overlapped with one DL subband for the symbol group, the PRB subset of the symbol group is not excluded, i.e. according to B _CI A frequency domain PRB group is calculated.

If the allocated resources of the previously scheduled terminal fall within the time-frequency region indicated by the uplink CI, the terminal will cancel the previously scheduled transmission.

In order to more clearly describe the cancellation indication method in the full duplex scenario provided in the embodiment of the present application, the following description is made with reference to an example.

Example 2

An example of CI indication in full duplex is shown in fig. 10. Corresponding to one SCS u, the network is configured as DL slot for slot n and UL slot for slot n+1, e.g. by TDD-UL-DL-configuration command signaling.

Further, the network is configured with UL subbands on slot n and DL subbands on slot n+1. For UL subbands on DL slots of the network configuration, PRBs of DL subbands of the UL slots may be excluded when indicated using CI. UL subbands in DL slots of the network configuration should be included in the CI indication, i.e. this part of the symbols should not be excluded.

Fig. 11 shows an example of full duplex, where the network configures UL-DL ratio of two slots by the configuration parameter TDD-UL-DL-configuration command, the 1 st slot is 7 DL symbols, 7 UL symbols. In the second slot,2 DL symbols, 12 UL symbols.

UL subbands are arranged on DL symbols on slot n. Since the DL symbols contain UL subbands, the DL symbols should not be excluded at the time of symbol grouping.

Since slot n+1 has 2 DL symbols, these symbols should be excluded when the symbols are grouped. The number of symbols involved in the packet is 26. The first 2 groups of 6 symbols each and the second 2 groups of 7 symbols each.

For PRB determination, PRBs that fall entirely on DL subbands for a certain symbol group may be excluded. Because these PRBs are not cancelled by the CI indication, e.g. DL subbands of the first 6 symbols in slot n. Likewise, for DL subbands included in the UL symbol, if the PRBs completely overlap with the UL subbands for one symbol group, the PRBs should be excluded. This improves the accuracy of the indication and in fact it is a matter of determining the granularity of the indication per symbol group.

For example, the time domain region where CI acts contains 26 symbols (two DL symbols including UL subband are excluded), divided into 4 symbol groups.

The 1 st symbol group may use PRBs of the valid frequency domain region, i.e., b_ci_ul subframe 1;

the frequency domain indication granularity N_BI is calculated according to N_CI and G_CI;

front faceThe symbol group comprisesEach PRB;

the remainderThe symbol group comprises->And the number of PRBs.

The 2 nd symbol group and the 3 rd symbol group have subbands of different directions, no PRB subset (across all symbols) falls completely on the DL subband, so the frequency domain indication granularity calculation uses the frequency domain region B _CI PRB number calculation of (a).

Frequency domain indication granularity calculation for 4 th symbol group uses frequency domain region B _CI PRB number calculation of (a).
