[0029] see figure 1 , figure 1 is a flowchart of the channel resource sharing processing method provided by the embodiment of the present invention, such as figure 1 As shown, the channel resource sharing processing method is applied to a mobile communication terminal, and includes the following steps:

[0030] Step 101 , after the mobile communication terminal succeeds in LBT (Listen Before Talk), the corresponding maximum channel occupation duration MCOT (Max Channel Occupy Time) is determined according to the parameters of the LBT. For example, the determination of the MCOT is based on the channel access priority, whether there is an interval, and whether there is other technology abstractOfAnyOtherTechnology-r14 indicated by high-level signaling.

[0031] The channel resource sharing processing method provided by the embodiment of the present invention is mainly applied in a communication system, and is used for sharing resources within a channel occupation time obtained...

[0039] It should be understood that when the uplink transmission is converted into the downlink transmission, the network side equipment needs to perform LBT again, so the time interval between the uplink transmission and the downlink transmission needs to be set, and the setting of the time interval can be set according to actual needs. For example, in this embodiment, the start time of the downlink transmission may be indicated in the manner of the above-mentioned control information. Specifically, refer to figure 2 , the above-mentioned instructing the network side device to perform downlink transmission in the MCOT after the completion of the autonomous scheduling of uplink transmission includes:

[0040] The first interval configuration information that instructs the network-side device to perform autonomous scheduling of uplink transmission and downlink transmission interval time within the MCOT.

[0041] In this embodiment, the first interval configuration information...

Abstract

The invention provides a channel resource sharing treatment method, mobile communication terminal and network side equipment. The method comprises the steps of after the mobile communication terminalis succeeded to perform listen before talk (LBT), determining a corresponding maximum channel occupancy time (MCOT) according to a parameter of the LBT; performing autonomously scheduling uplink transmission within the MCOT, wherein the autonomously scheduling uplink transmission carries uplink control information which is used for instructing the network side equipment to execute the autonomouslyscheduling uplink transmission of the mobile communication terminal, and instructing the network side equipment to execute downlink transmission in the MCOT after the autonomously scheduling uplink transmission is completed. In the MCOT acquired by the autonomously scheduling uplink transmission of the mobile communication terminal, the downlink transmission of the network side equipment can be performed within the residual time after the uplink transmission is performed, so that sharing of channel resources in the MCOT is achieved, and the utilization rate of the channel resources is improved.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a channel resource sharing processing method, a mobile communication terminal and a network side device. Background technique [0002] As we all know, based on the defect that the uplink transmission scheme using centralized scheduling of base stations in wireless communication systems requires multiple LBTs, in MulteFire, an uplink transmission scheme based on autonomous scheduling of mobile communication terminals UE is proposed, namely AUL (Autonomous UpLink) or GUL (Grant -less UpLink). Since the UE is allowed to initiate uplink transmission autonomously, the delay and the number of LBTs are reduced. [0003] In the existing transmission based on base station scheduling, the base station performs Cat-4LBT (the channel access process including PDSCH transmission defined in 3GPP TS36.213), and after the channel access is successful, the corresponding MCOT (maximum ch...
