Problems solved by technology

[0005] The purpose of the technical solution of the present invention is to provide a method for sending uplink control information, a terminal and a network side device, which are used to solve the problem that the UCI of the eMBB service in the prior art cannot be sent to the base station normally, and the base station needs to retransmit the HARQ-ACK contained in the UCI The corresponding downlink data of the information causes the problem of waste of downlink transmission resources

Embodiment 1

[0171] like image 3 As shown, in the target slot, all time-domain symbol resources of eMBB PUSCH overlap with URLLC PUSCH, then all resources of eMBB PUSCH will be indicated as not to be transmitted by the downlink control information, and other resources other than the resources indicated as not to be transmitted The number of resource blocks N=0, that is, the resources indicated as not to be transmitted do not include other resources, and the eMBB terminal does not transmit the PUSCH nor transmit the UCI.

Embodiment 2

[0173] like Figure 4 As shown, in the target slot, the fourth and fifth time domain symbols of eMBB PUSCH overlap with URLLC PUSCH, and will be indicated as not to be transmitted by the downlink control information, and other resources other than the resources indicated as not to be transmitted are the first three time-domain symbols that do not overlap with URLLC PUSCH. If it is determined that at least two consecutive time domain symbols in other resources form a resource block, then the first three time domain symbols of the eMBB PUSCH may form a resource block, that is, N=1. When the composed resource block meets the multiplexing condition of UCI, UCI can be sent through the resource block; when the composed resource block does not meet the multiplexing condition of UCI, the eMBB terminal neither transmits PUSCH nor transmits UCI.

Embodiment 3

[0175] like Figure 5 As shown, in the target slot, the fourth and fifth time domain symbols of eMBB PUSCH overlap with URLLC PUSCH, and will be indicated as not to be transmitted by the downlink control information, and other resources other than the resources indicated as not to be transmitted are the first three The first time-domain symbols and the last two time-domain symbols do not overlap with URLLC PUSCH. If it is determined that at least two consecutive time domain symbols in other resources form a resource block, then the first three time domain symbols of eMBB PUSCH may form a resource block, and the last two time domain symbols may form a resource block, That is, N=2. If both resource blocks meet the multiplexing conditions of UCI at this time, the resource block with a longer time domain length is preferentially selected, that is, the resource block composed of the first three time domain symbols is the target resource for sending UCI.

Abstract

The invention provides an uplink control information sending method, a terminal and network side equipment. The method comprises the following steps: in a target time slot, if multiplexed uplink control information (UCI) exists on a physical uplink shared channel (PUSCH) resource to be sent, but at least part of resources of the PUSCH resource are indicated not to be sent by downlink control information, sending the UCI through a target resource. Using the method, when the PUSCH resource of the eMBB service is indicated to be occupied by the downlink control information; when the multiplexed UCI exists on the time-frequency resource of the PUSCH resource, the PUSCH resource is retransmitted; the UCI is sent through the target resource, so that the UCI multiplexed on the PUSCH resource canbe normally sent to the base station, and the problem of downlink transmission resource waste caused by the fact that the base station needs to retransmit the downlink data corresponding to the HARQ-ACK information contained in the UCI is prevented.

Description

technical field [0001] The present invention relates to the field of wireless technology, and in particular, to a method for sending uplink control information, a terminal and a network side device. Background technique [0002] In the existing uplink transmission, the time-frequency resources of the Physical Uplink Control Channel (PUCCH) and the Physical Uplink Shared Channel (PUSCH) in the same time slot overlap in the time domain. At this time, if the conditions of Uplink Control Information (UCI) multiplexing (UCI multiplexing) are met, the terminal will multiplex the UCI sent on the PUCCH on the time-frequency resources of the PUSCH. At this time, the terminal will only send the PUSCH without sending PUCCH. [0003] After the introduction of uplink multi-service resource multiplexing, the transmission of burst uplink Ultra Reliable & Low Latency Communication (uRLLC) services is allowed to preferentially occupy the scheduled uplink Mobile Broadband (Enhance Mobile Bro...
