The disclosure relates to the field of communication, and particularly to a method for configuring transmission resource cancelation indication information, a terminal device, and a network device.
In a New Radio (NR) system, two services, i.e., Ultra-Reliable Low Latency Communication (URLLC) and Enhanced Mobile Broadband (eMBB), are introduced. URLLC has a characteristic of implementing ultra-reliable (for example, 99.999%) transmission in an extremely low latency (for example, 1 ms), and eMBB has a characteristic of insensitivity to a latency but support of a large number of transmissions. In a scenario where URLLC and eMBB coexist, for implementing real-time transmission of URLLC, when URLLC and eMBB transmissions conflict, URLLC and eMBB may interfere with each other, which influences demodulation performance of URLLC. Retransmission may reduce the influences but may prolong a transmission latency of URLLC.
A present solution to the problem of Uplink (UL) transmission conflicts of URLLC and eMBB is to stop eMBB transmission to reduce interferences to URLLC. For a multi-carrier condition, when signal transmission on a certain carrier is interrupted, transmission at the same time position on another carrier is also required to be interrupted. For example, in case of simultaneous transmission on Component Carrier 1 (CC1) and a CC2, if the same Subcarrier Spacing (SCS) is used for CC1 and CC2, a signal interruption condition is illustrated by case 1 in
The network side may notify an eMBB user of a resource occupation condition of a URLLC service through transmission resource cancelation indication information such that the eMBB user stops eMBB transmission to reduce interferences to URLLC. Therefore, how to configure the transmission resource cancelation indication information to simplify the signal interruption processing and improve efficiency of a communication system is a problem that needs to be solved at present.

In one example, the communication system 100 may further include another network entity such as a network controller and a mobility management entity. No limits are made thereto in the embodiments of the disclosure.
It is to be understood that a device with a communication function in the network/system in the embodiments of the present disclosure may be referred to as a communication device. Taking the communication system 100 illustrated in
It is to be understood that terms “system” and “network” in the disclosure may usually be interchanged in the disclosure. In the disclosure, the term “and/or” is only an association relationship describing associated objects and represents that three relationships may exist. For example, A and/or B may represent three conditions: i.e., independent existence of A, existence of both A and B, and independent existence of B. In addition, character “I” in the disclosure usually represents that previous and next associated objects form an “or” relationship.
There are two services, URLLC and eMBB, in an NR system. URLLC has a characteristic of implementing ultra-reliable (for example, 99.999%) transmission in an extremely low latency (for example, 1 ms), and eMBB has a characteristic of insensitivity to a latency but support of a large number of transmissions. In a scenario where URLLC and eMBB coexist, for implementing real-time transmission of URLLC, when URLLC and eMBB transmissions conflict, URLLC and eMBB may interfere with each other, which influences the demodulation performance of URLLC. Retransmission may reduce the influences but may prolong a transmission latency of URLLC.
A present solution to the problem of UL transmission conflicts of URLLC and eMBB is to stop eMBB transmission to reduce interferences to URLLC. The network side may notify an eMBB user of a resource occupation condition of a URLLC service through transmission resource cancelation indication information such that the eMBB user stops eMBB transmission to reduce interferences to URLLC.
In the related art, a reference time region of the transmission resource cancelation indication information (for example, Uplink Cancelation Indication (UL CI) or Uplink Cancelation Information (UL CI)) is configurable, and during configuration, symbol is taken as a unit. For example, in case of simultaneous transmission on CC1 and CC2, if the same SCS is used for CC1 and CC2, a signal interruption condition is illustrated by case 1 in
Based on the related art, a problem required to be solved at present is how to configure the transmission resource cancelation indication information to simplify a signal interruption processing and improve the efficiency of a communication system.
Therefore, the embodiments of the disclosure provide a method for configuring transmission resource cancelation indication information. Configuration information of the transmission resource cancelation indication information includes at least one of a reference time region, a reference frequency region, a transmission resource cancelation indication bit number, a time indication granularity, or information used for determining a starting point offset of the transmission resource cancelation indication information. Therefore, under a multi-carrier condition, when transmission resource cancelation indication information is configured for each carrier, reference time positions and time indication granularities of the same time length are used to further simplify a signal interruption processing under the multi-carrier condition and improve the system efficiency.
As illustrated in
As illustrated in
It is to be understood that, after the terminal device receives the configuration information from the network device, the terminal device may parse the transmission resource cancelation indication information based on the configuration information to obtain a resource position where transmission is canceled.
It is to be noted that, if there is no information used for determining the starting point offset of the transmission resource cancelation indication information in the configuration information, the terminal device may determine the starting point offset of the transmission resource cancelation indication information based on the terminal capability.
In some embodiments, a starting point of the first reference time region may be defined based on the following manners.
First manner: if a UE detects transmission resource cancelation indication information (UL CI) in a Physical Downlink Control Channel (PDCCH) transmitted in a Control Resource Set (CORESET) in a slot, reference time region starts from X·2μ-μ
Second manner: if a UE detects a UL CI in a PDCCH transmitted in a CORESET in a slot, reference time region starts from X symbols after the ending symbol of the PDCCH CORESET carrying the UL CI, where X is configured by the value of Preemption-to-reference time region timing for serving cell with mapping to a respective field in the UL CI.
In some embodiments, a time length corresponding to the first reference time region may be defined based on the following manners.
First manner: the duration of reference time region is T, where T is configured by the value of reference time region duration for serving cell with mapping to a respective field in the UL CI.
Second manner: the duration of reference time region is TRTR·2μ-μ
As an example, the first reference time region is independently configured for different carriers. Alternatively, it can be understood that the first reference time region may be independently configured for each carrier. It is assumed that reference time regions are required to be configured for two carriers (CC1 and CC2), an SCS corresponding to CC1 is 15 kHz, a time length corresponding to each symbol is t1, an SCS corresponding to CC2 is 30 kHz, and a time length corresponding to each symbol is t2, t1=t2*2.
As illustrated in
Alternatively, as illustrated in
Alternatively, as illustrated in
As another example, the reference time region of each carrier is determined based on an SCS of each carrier and the first reference time region, and the first reference time region corresponds to a first SCS. The first SCS is configured by the network device, or the first SCS is predetermined in a protocol. When the first SCS is configured by the network device, the configuration information further includes the first SCS.
For example, as illustrated in
Based on the above embodiment, the first SCS is an SCS of a carrier carrying the transmission resource cancelation indication information; or, the first SCS is a minimum SCS in SCSs of multiple carriers; or, the first SCS is a maximum SCS in the SCSs of the multiple carriers; or, the first SCS is a reference SCS used when a Slot Format Indication (SFI) is configured; or, the first SCS is a minimum SCS in SCSs corresponding to Frequency Range 1 (FR1); or, the first SCS is a maximum SCS in the SCSs corresponding to FR1; or, the first SCS is a minimum SCS in SCSs corresponding to FR2; or, the first SCS is a maximum SCS in the SCSs corresponding to FR2; or, the first SCS is an SCS indicated in physical signaling.
The first SCS is a downlink SCS. Alternatively, the first SCS is a UL SCS.
As a specific example, a value of the first reference time region includes one of the following: 1 symbol, 2 symbols, 4 symbols, 7 symbols, 14 symbols, 21 symbols, 28 symbols, 35 symbols, or 42 symbols.
As a specific example, the value of the first reference time region is M*2n symbols, n being a nonnegative integer, and M being a positive integer. Considering a relationship between symbol lengths of different SCSs is 2n, n being a serial number difference of the SCSs, for ensuring that the same time length may be configured for reference time regions of carriers using different SCSs, M*2n symbols are introduced. Typically, M=1, 2, 4, 7, and n=0, 1, 2. Therefore, the value of the first reference time region also includes one of the following: 1*2n, 2*2n, 4*2n, or 7*2n. In some embodiments, the time length corresponding to the first reference time region is more than or equal to a period of a search space carrying the transmission resource cancelation indication information.
In some embodiments, reference time regions of different carriers correspond to the same time length.
As another example, the first time indication granularity is independently configured for different carriers. Alternatively, the first time indication granularity may be independently configured for each carrier. In one example, a time length corresponding to the first time indication granularity is less than or equal to the time length corresponding to the first reference time region.
For example, as illustrated in
Alternatively, as illustrated in
As another example, the time indication granularity of each carrier is determined based on an SCS of each carrier and the first time indication granularity, and the first time granularity corresponds to a second SCS. The second SCS is configured by the network device, or the second SCS is predetermined in the protocol. When the second SCS is configured by the network device, the configuration information further includes the second SCS.
In one example, the second SCS is an SCS of the carrier carrying the transmission resource cancelation indication information; or, the second SCS is a minimum SCS in SCSs of multiple carriers; or, the second SCS is a maximum SCS in the SCSs of the multiple carriers; or, the second SCS is a reference SCS used when an SFI is configured; or, the second SCS is the minimum SCS in the SCSs corresponding to FR1; or, the second SCS is the maximum SCS in the SCSs corresponding to FR1; or, the second SCS is the minimum SCS in the SCSs corresponding to FR2; or, the second SCS is the maximum SCS in the SCSs corresponding to FR2; or, the second SCS is an SCS indicated in the physical signaling.
In the embodiment of the disclosure, the second SCS is a downlink SCS. Alternatively, the second SCS is a UL SCS.
For example, as illustrated in
It is assumed that time indication granularities are required to be configured for two carriers (CC1 and CC2), an SCS corresponding to CC1 is 15 kHz, a time length corresponding to each symbol is t1, an SCS corresponding to CC2 is 30 kHz, and a time length corresponding to each symbol is t2, t1=t2*2. The reference SCS is an SCS of 30 kHz used when the transmission resource cancelation indication information is transmitted, and a time length corresponding to each symbol is t2. If the time length corresponding to the first time indication granularity required to be configured is T3=t1, since the reference SCS is 30 kHz, the time length corresponding to each symbol is t2, and 2 symbols are required to reach T3, the time indication granularity required to be configured for CC1 is 2symbol, and the time indication granularity required to be configured for CC2 is 2symbol. A downlink SCS is used as the reference SCS, but the transmission resource cancelation indication information is configured to indicate a UL transmission resource. Indication of the time indication granularity through the reference downlink SCS may ensure that the indicated time resource range is matched with a period of the indication information, thereby avoiding missing coverage or repeated coverage.
Alternatively, as illustrated in
As an example, the starting point of the first reference time region is determined based on transmission ending time of the transmission resource cancelation indication information and the starting point offset of the transmission resource cancelation indication information. Alternatively, it is understood that the starting point offset (X) of the transmission resource cancelation indication information is a time interval between the transmission ending time of the transmission resource cancelation indication information and the time starting point of the first reference time region.
Configuration methods for the starting point offset of the transmission resource cancelation indication information will be described below with specific examples. It is assumed that time indication granularities are required to be configured for two carriers (CC1 and CC2), an SCS corresponding to CC1 is 15 kHz, a time length corresponding to each symbol is t1, an SCS corresponding to CC2 is 30 kHz, and a time length corresponding to each symbol is t2, t1=t2*2.
First configuration method: as illustrated in
Second configuration method: it is configured or predetermined in the protocol that the reference SCS is 30 kHz, and the time length corresponding to each symbol is t2. If the time length corresponding to the starting point offset of the transmission resource cancelation indication information is T8=2*t1, since the reference SCS is 30 kHz, the time length corresponding to each symbol is t2, and 4 symbols are required to reach T8, the starting point offset of the transmission resource cancelation indication information required to be configured for CC1 is 2symbol, and the starting point offset of the transmission resource cancelation indication information required to be configured for CC2 is 4symbol.
As an example, the starting point of the first reference time region is determined based on a last symbol of a CORESET where the transmission resource cancelation indication information is located and the starting point offset of the transmission resource cancelation indication information. Alternatively, it is understood that the starting point offset of the transmission resource cancelation indication information is a time interval between the last symbol of the CORESET where the transmission resource cancelation indication information is located and the time starting point of the first reference time region.
The methods for configuring the information used for determining the starting point offset of the transmission resource cancelation indication information will be described below with specific examples. It is assumed that time indication granularities are required to be configured for two carriers (CC1 and CC2), an SCS corresponding to CC1 is 15 kHz, a time length corresponding to each symbol is t1, an SCS corresponding to CC2 is 30 kHz, and a time length corresponding to each symbol is t2, t1=t2*2.
First configuration method: as illustrated in
Second configuration method: it is configured or predetermined in the protocol that the reference SCS is 30 kHz, and the time length corresponding to each symbol is t2. If the time length corresponding to the information used for determining the starting point offset of the transmission resource cancelation indication information is T8=2*t1, since reference SCS is 30 kHz, the time length corresponding to each symbol is t2, and 4 symbols are required to reach T8, the information configured for CC1 to determine the starting point offset of the transmission resource cancelation indication information is 2symbol, and the information configured for CC2 to determine the starting point offset of the transmission resource cancelation indication information is 4symbol.
Based on the above embodiments, the information used for determining the starting point offset of the transmission resource cancelation indication information is independently configured for different carriers. Alternatively, the information used for determining the starting point offset of the transmission resource cancelation indication information is predetermined in the protocol. For example, the information used for determining the starting point offset of the transmission resource cancelation indication information is related to time N2 during which the terminal processes a UL shared data channel, or the information used for determining the starting point offset of the transmission resource cancelation indication information is related to Tproc,2. Tproc,2 is a minimum interval between a starting symbol of a Physical Uplink Shared Channel (PUSCH) and an ending position of a UL grant, a specific definition of which refers to 38.214. When Tproc,2 is used to determine the starting point offset of the transmission resource cancelation indication information, d2,1=0.
In some embodiments, information configured for each carrier to determine a starting point offset of the transmission resource cancelation indication information is determined based on an SCS of each carrier and the information used for determining the starting point offset of the transmission resource cancelation indication information, and the information used for determining the starting point offset of the transmission resource cancelation indication information corresponds to a third SCS.
In some embodiments, the third SCS is configured by the network device, or the third SCS is predetermined in the protocol.
In some embodiments, the configuration information further includes third SCS information.
In some embodiments, the third SCS is an SCS of the carrier carrying the transmission resource cancelation indication information; or, the third SCS is a minimum SCS in SCSs of multiple carriers; or, the third SCS is a maximum SCS in the SCSs of the multiple carriers; or, the third SCS is a reference SCS used when the SFI is configured; or, the third SCS is a minimum SCS in the SCSs corresponding to FR1; or, the third SCS is a maximum SCS in the SCSs corresponding to FR1; or, the third SCS is a minimum SCS in the SCSs corresponding to FR2; or, the third SCS is a maximum SCS in the SCSs corresponding to FR2; or, the third SCS is an SCS indicated in the physical signaling.
In the embodiment of the disclosure, the third SCS is a downlink SCS. Alternatively, the third SCS is a UL SCS.
In some embodiments, the time length corresponding to the information used for determining the starting point offset of the transmission resource cancelation indication information is less than or equal to a period of the search space where the transmission resource cancelation indication information is located.
In some embodiments, information configured for different carriers to determine a starting point offset of the transmission resource cancelation indication information corresponds to the same time length.
It is to be understood that, in each embodiment of the disclosure, a magnitude of a sequence number of each process does not mean an execution sequence and the execution sequence of each process should be determined by its function and an internal logic and should not form any limit to an implementation process of the embodiments of the disclosure.
