The main scenarios of New Radio (NR) include Enhance Mobile Broadband (eMBB), Massive Machine Type of Communication (mMTC), and Ultra-Reliable & Low Latency (Ultra-Reliable&Low Latency). Communication, URLLC), these scenarios put forward requirements for the system such as high reliability, low latency, large bandwidth, and wide coverage.

These different services have different Quality of Service (QoS) requirements. For example, URLLC supports low-latency, high-reliability services. In order to achieve higher reliability, a lower code rate needs to be used to transmit data, and at the same time, a faster and more accurate channel state information (CSI) feedback is needed. eMBB services support high throughput requirements, but are not as sensitive to delay and reliability as URLLC. In addition, some terminals (user equipment, UE) may support services with different numerical configuration (numerology). The UE not only supports URLLC low-latency and high-reliability services, but also supports large-capacity and high-rate eMBB services.

According to the mechanism in related technologies, eMBB services are usually transmitted through the Physical Uplink Control Channel (PUCCH), Sounding Reference Signal (SRS), and Physical Random Access Channel (PRACH). The transmission of PUCCH, SRS, and PRACH is configured by network equipment. The transmission of URLLC service is dynamically scheduled by network equipment. URLLC transmission may be scheduled to time-frequency resources that overlap with the transmission resources of eMBB services. At this time, the terminal usually cancels the uplink transmission of the eMBB service directly according to the uplink cancellation instruction sent by the network device, which will have a greater impact on the transmission of the eMBB service.

Further, the aforementioned resource pattern may be a cell-specific or terminal-specific (UE-specific) configuration.

In order to better understand the present disclosure, the implementation process of the present disclosure will be described in detail below through specific examples.

In solution 1: As shown in Figure 3, UE1 receives an uplink cancellation instruction sent by a network device, and the time domain indication information indicated by the uplink cancellation instruction indicates that the cancelled resource is the transmission resource corresponding to the physical uplink shared channel in Figure 3 . The time domain indication information is slot N symbols 6-8, and the frequency domain indication information is PRB 1-30; the physical uplink shared channel in Figure 3 may be an uplink channel for network equipment to schedule UE2 for uplink transmission.

If UE1 is configured with PUCCH resources in symbols 4-9 of slot N (frequency domain resources are PRB 1-10), and UE1 will send PUCCH in this slot, because the time domain resource indicated by the uplink cancel command and the PUCCH resource are in time-frequency There is overlap in the domain, so in slot N, UE1 does not cancel the transmission of the PUCCH.

In solution 2: As shown in Figure 4, UE1 receives an uplink cancel instruction sent by a network device, and the time domain indication information indicated by the uplink cancel instruction indicates that the resource to be cancelled is the transmission corresponding to the physical uplink shared channel 1 in Figure 4 Resources. The time domain indication information is slot N symbols 6-8, and the frequency domain indication information is PRB 1-30; the physical uplink shared channel 1 in Figure 4 may be an uplink channel for network equipment to schedule UE2 for uplink transmission.

If UE1 schedules the transmission of physical uplink shared channel 2 in the symbol 4-12 of slot N, and the frequency domain resource is PRB 6-20, the time domain resource indicated by the uplink cancel command and the resource corresponding to the physical uplink shared channel 2 are in time There is overlap in the frequency domain, so the UE cancels the transmission of the physical uplink shared channel 2;

If UE1 is configured with PUCCH resources in symbols 4 to 9 of slot N (frequency domain resources are PRB 1 to 6), and UE1 will send PUCCH in this slot, because the time domain resource indicated by the uplink cancel command and the PUCCH resource are in time and frequency There is overlap in the domain, so in slot N, UE1 does not cancel the transmission of the PUCCH.

In solution 3: As shown in FIG. 3, UE1 receives an uplink cancel instruction sent by a network device, and the uplink cancel instruction indicates time domain indication information and/or frequency domain indication information. The network device is configured with the frequency domain resource pattern (0000000011). This embodiment assumes that the number of bits of the frequency domain indication information of the uplink cancel command is 10 bits, and each bit indicates 5 PRBs. The bit "1" in the pattern is used to instruct the UE not to cancel. The uplink channel corresponding to the pattern, specifically, the resource indicated by the pattern to be cancelled is the transmission resource corresponding to the physical uplink shared channel in FIG. 3. The physical uplink shared channel in FIG. 3 may be an uplink channel for the network device to schedule UE2 for uplink transmission.

If the frequency domain indication information indicated by the uplink cancellation command received by UE1 is (0000111111), UE1 compares the frequency domain indication information of the uplink cancellation command with the frequency domain pattern configured by the network, and the frequency domain indication information overlaps with the pattern. The indicated resource, UE1 does not cancel the uplink channel in the overlapping area

As shown in Figure 3, UE1 receives an uplink cancellation instruction (Uplink cancellation indication, UL CI), indicating the frequency domain resource location of URLLC PUSCH, and the frequency domain resource pattern configured by the network overlaps with the frequency domain resource location indicated by the uplink cancellation instruction Therefore, UE1 does not cancel the transmission of PUCCH in the overlapping area.
