In order to facilitate understanding of the embodiments of the present invention, the UL PI will be briefly described below.
For the URLLC service, due to the bursty characteristic, dedicated transmission resources may not appear for a long time, and in this scenario, idle resources may appear to cause a reduction in transmission efficiency, so the resources of the URLLC service may be multiplexed with the resources of the eMBB service. Under the multiplexing condition, after a base station (next generation NB, gNB) sends an uplink transmission scheduling grant to the eMBB terminal, there may be a service arrival of the URLLC terminal, and at this time, an UL PI needs to be sent to the eMBB terminal to notify the eMBB terminal to cancel uplink transmission or reduce transmission power, so as to protect the reliability of the URLLC terminal transmission.
There are two cases for UL PI:
(1) after the UL PI appears in the eMBB Uplink grant (UL grant), and before a Physical Uplink Shared Channel (PUSCH) is sent, the eMBB terminal receives the UL PI, and may stop the entire Uplink transmission.
(2) The UL PI appears during the transmission of the eMBB PUSCH, and the eMBB terminal receives the UL PI and discards the subsequent partial symbol and/or the subsequent uplink transmission.
At present, the transmission mode of UL PI for a network and a terminal is not specified.
Embodiments of the present invention are described below with reference to the accompanying drawings. The uplink priority occupation indication method and the uplink priority occupation indication equipment provided by the embodiment of the invention can be applied to a wireless communication system. Referring to fig. 1, an architecture diagram of a wireless communication system according to an embodiment of the present invention is shown. As shown in fig. 1, the wireless communication system may include: a network device and a terminal device 10, wherein the terminal device is denoted as a User Equipment (UE) 11, the UE11 may communicate (transmit signaling or transmit data) with the network device 10. In practical applications, the connections between the above devices may be wireless connections, and fig. 1 illustrates the connections between the devices by solid lines for convenience and convenience in visual representation. It should be noted that the communication system may include a plurality of UEs 11, and the network device 10 may communicate with a plurality of UEs 11.

Referring to fig. 2, an embodiment of the present invention provides an uplink priority occupancy indication method, where an execution subject of the method may be a network device, and the method includes the following specific steps:
step 201: and sending a plurality of UL PIs to the terminal, wherein the UL PIs are used for indicating the terminal to cancel uplink transmission or reduce the resource of uplink transmission power.
Wherein the resource may be one or more of a time domain resource, a frequency domain resource, and a time frequency domain resource.
In the embodiment of the present invention, optionally, the resources of the multiple UL PI indications sent by the network device may be the same or different. Sending multiple UL PIs is beneficial to ensure the reliability of the transmission.
If multiple UL PIs sent by the network device indicate the same resource. The terminal receives a plurality of UL PIs indicating the same resource, and the terminal may consider the plurality of UL PIs as one UL PI.
If multiple UL PIs sent by the network device indicate different resources. The terminal may cancel the corresponding uplink transmission or reduce the uplink transmission power of the corresponding resource according to the resource indicated by each UL PI. The terminal may also cancel the corresponding uplink transmission or reduce the uplink transmission power of the corresponding resource according to the resource indicated by the last received UL PI. The network device may instruct the terminal to cancel uplink transmission of the corresponding resource or reduce uplink transmission power of the corresponding resource according to the sequence of receiving the UL PI.
For example: the first UL PI indicator K (symbol) received by the terminal starts cancelling (cancel) UL transmission, and the second UL PI indicator K + x (symbol K + x) received by the terminal starts cancelling UL transmission. When the network equipment indicates the terminal to cancel the uplink transmission according to the first received UL PI, the terminal starts to cancel the uplink transmission from the symbol K.
