Since the UE is allowed to autonomously initiate uplink transmission, the time delay and the LBT times are reduced.
In the existing transmission based on base station scheduling, a base station performs Cat-4LBT (channel access procedure including PDSCH transmission defined in 3GPP TS 36.213), and after channel access is successful, an eNB transmits a downlink signal and schedules a UE to transmit an uplink signal within a corresponding MCOT (maximum channel occupancy duration). For the autonomously scheduled uplink transmission, the UE may adopt Cat-4LBT (uplink channel access procedure of type1 defined in 3GPP TS 36.213) and successfully contend for the channel, so as to obtain MCOT (maximum channel occupancy duration) corresponding to the current channel access parameter (channel access priority), and may perform the autonomously scheduled uplink transmission of the UE within the MCOT. In order to meet all uplink transmission requirements, the MCOT duration is usually configured to be longer, and when the uplink transmission time requirement is less, the channel resources will be wasted.

Referring to fig. 1, fig. 1 is a flowchart of a channel resource sharing processing method according to an embodiment of the present invention, and as shown in fig. 1, the channel resource sharing processing method is applied to a mobile communication terminal, and includes the following steps:
The channel resource sharing processing method provided by the embodiment of the invention is mainly applied to a communication system and used for sharing the resources within the channel occupation time acquired by the autonomous scheduling of the mobile communication terminal so as to improve the utilization rate of the channel resources.
Specifically, when the mobile communication terminal needs to initiate autonomous scheduling uplink transmission, a Type1 uplink access flow (i.e., Cat-4 LBT) may be first adopted, and a priority of channel access is configured, after LBT is successful, a corresponding MCOT may be obtained, and a specific MCOT size may be determined by whether there are other access technologies, whether there are intervals of more than 100us, and a channel access priority together, which are indicated by a high-level signaling. In this embodiment, the channel access priority is a parameter for determining the MCOT, and may be configured in advance by a protocol, or configured by a mobile communication terminal, or configured by a network side device, which is not further limited herein. The length of the MCOT may be set according to actual needs, for example, in this embodiment, the MCOT may be 2ms, 3ms, 6ms, 8ms, or 10 ms. The autonomously scheduled UpLink transmission may be aul (autonomous UpLink) or GUL (Grant-less UpLink), and the following description will use the GUL as an example.
And 102, performing autonomous scheduling uplink transmission in the MCOT, wherein the autonomous scheduling uplink transmission carries uplink control information, and the uplink control information is used for instructing a network side device to perform autonomous scheduling uplink transmission of the mobile communication terminal and instructing the network side device to perform downlink transmission in the MCOT after the autonomous scheduling uplink transmission is completed.
In this step, the transmission duration of the autonomously scheduled uplink transmission may be set according to actual needs, specifically, the transmission duration of the autonomously scheduled uplink transmission is less than MCOT, for example, MCOT may be 6ms, and the autonomously scheduled uplink transmission is 2 ms. That is to say, in this embodiment, the uplink control information may instruct the network side device to perform downlink transmission on the time-frequency resources from 3ms to 6ms, where a receiving end corresponding to the downlink transmission may be a mobile communication terminal initiating autonomous scheduling uplink transmission, or may be another mobile communication terminal, and is not limited further here.
In this embodiment, when the time reaches the start time corresponding to the MCOT, the mobile communication terminal sends the autonomous scheduling uplink transmission to transmit corresponding uplink data and uplink control information, and the network side device may first receive the uplink data according to the indication of the uplink control information, and then perform downlink transmission after the uplink transmission is completed.
It should be understood that the setting of the start time of the downlink transmission may be performed according to actual needs, and is not limited herein, for example, the start time of the downlink transmission may be agreed by a predetermined protocol, the notification may be broadcast by a network side device, the indication may be performed by a mobile communication terminal, or a combined indication of at least two manners.
In this way, in the embodiment of the present invention, after the mobile communication terminal successfully performs listen before send LBT, the corresponding maximum channel occupation time MCOT is determined according to the parameters of LBT and the like; and performing autonomous scheduling uplink transmission in the MCOT, wherein the autonomous scheduling uplink transmission carries uplink control information, and the uplink control information is used for instructing network side equipment to perform the autonomous scheduling uplink transmission of the mobile communication terminal and instructing the network side equipment to perform the autonomous scheduling uplink transmission and then perform downlink transmission in the MCOT. In the MCOT obtained by the autonomous scheduling uplink transmission of the mobile communication terminal, after the uplink transmission is carried out, the downlink transmission of the network side equipment can be carried out in the remaining time, thereby realizing the sharing of the channel resources in the MCOT and improving the utilization rate of the channel resources.
Second embodiment
It should be understood that when the uplink transmission is converted into the downlink transmission, the network side device needs to perform LBT again, so that the time interval between the uplink transmission and the downlink transmission needs to be set, and the setting of the time interval may be set according to actual needs. For example, in this embodiment, the start time of downlink transmission may be indicated by using the above control information. Specifically, referring to step 1021 in fig. 2, the instructing, by the network side device, the network side device to perform downlink transmission in the MCOT after completing the autonomous scheduling uplink transmission includes:
and indicating the network side equipment to execute the first interval configuration information of the interval time of the autonomous scheduling uplink transmission and the downlink transmission in the MCOT.

Specifically, the manner of indicating the time domain position of the downlink transmission may be set according to actual needs, for example, an approximate position may be indicated, and then the start time of starting the downlink transmission is determined according to a preset sending rule, or the start subframe position of the downlink transmission may be indicated. This is explained in detail below:
for example, in the above embodiment, the MCOT may be 6ms, and the following indication manner may be adopted for the indication of the starting subframe position of the downlink transmission. Indicating that the autonomous scheduling uplink transmission is 2ms, and the last subframe can end at the last but one symbol, the time domain position of the network side device is 3ms to 6ms (i.e. the remaining MCOT is occupied), and the downlink transmission is sent at the subframe boundary starting at the 3 rd ms.
In addition, the time interval configuration of uplink transmission and downlink transmission can be carried out through a cell-level timing advance cell-specific TA. That is, in this embodiment, the performing autonomously scheduled uplink transmission in the MCOT includes: and controlling the advance time for starting the autonomous scheduling of the uplink transmission based on the cell-specific TA and the MCOT of the timing advance of the cell level carried in the system broadcast message of the network side equipment. The mobile communication terminal can be controlled to send the autonomously scheduled uplink transmission in advance, so that a time interval is formed between the uplink transmission and the downlink transmission, and the time interval is used for the network side equipment to carry out LBT.
That is to say, for the interval between uplink transmission and downlink transmission, the time interval between uplink transmission and downlink transmission may be implemented by one or more combinations of the last symbol of the last subframe of uplink transmission being autonomously scheduled for performing puncturing (puncturing), the cell-specific timing advance (cell-specific TA) and the downlink transmission subframe starting at the second slot or the first slot.
It should be noted that, for the LEB for downlink transmission, the network side device needs to determine the type of LBT and/or the channel access priority, and the specific implementation manner may be various, for example, the LBT may be determined by itself in the network side device, or may be determined based on the existing standard protocol, and may also use the above-mentioned control information for indication. When the indication is performed by using the uplink control information, specifically, the uplink control information is further used to indicate a type of LBT and/or a channel access priority corresponding to downlink transmission performed by the network side device in the MCOT.
Further, the content of the uplink control information may be set according to actual needs, for example, in this embodiment, the uplink control information includes at least one of a cell Radio network temporary identity (C-rnti), a size of the MCOT, a length of an autonomously scheduled uplink transmission, a position of the starting subframe, and second interval configuration information between adjacent subframes, where the second interval configuration information includes the first interval configuration information.

Specifically, in this embodiment, the downlink Control Information may include a PDCCH (physical downlink Control Channel) or an EPDCCH (Enhanced physical downlink Control Channel) scrambled by a C-RNTI (radio network temporary identity), and is used for transmitting ACK/NACK, CSI (Channel State Information) feedback, scheduling uplink and downlink transmission, and the like; the Downlink control information may further include a PDCCH scrambled by a CC-RNTI for broadcasting uplink transmission information, and the Downlink control information may further include a PDSCH (Physical Downlink Shared Channel) for data transmission/system information, and the like.

Further, after the downlink transmission is completed, the mobile communication terminal initiating the autonomous scheduling uplink transmission or other mobile communication terminals may be triggered to perform uplink transmission in the MCOT, so as to further improve the utilization rate of channel resources in the MCOT. That is, in the downlink transmission, in addition to the downlink (PDCCH) scrambled by the C-RNTI corresponding to the mobile communication terminal initiating the autonomous scheduling uplink transmission, other PDCCH, EPDDCH, PDSCH, etc. scrambled by the RNTI, for example, C-PDCCH that is the PDCCH scrambled by the CC-RNTI may be transmitted. In this embodiment, the downlink control information may be used to instruct the mobile communication terminal to trigger uplink transmission and/or schedule uplink transmission in the MCOT.
Specifically, as shown in fig. 4, for example, the network side device may indicate the triggered uplink transmission SUL through a C-PDCCH (PDCCH scrambled by CC-RNTI) (that is, trigger a is sent in UL grant, and trigger B is sent in C-PDCCH).
Optionally, referring to fig. 5, after the step of sending uplink control information in the MCOT, the method further includes:
and 103, acquiring downlink control information fed back by the network side equipment based on the autonomous scheduling uplink transmission.
In this step, downlink control information such as transmission acknowledgement characters ACK/NACK and CSI for autonomously scheduled uplink transmission is fed back to each mobile communication terminal network side device. The feedback mode for inputting the confirmation characters can be set according to actual needs.
For example, in an embodiment, the downlink control information is further used to feed back a transmission acknowledgement character corresponding to a hybrid Automatic Repeat request harq (hybrid Automatic Repeat request) process of PUSCH transmission on a physical uplink shared channel on each subframe.
In another embodiment, the downlink control information is further used to feed back transmission acknowledgement characters of hybrid automatic repeat request HARQ processes of all to-be-fed back physical uplink shared channel PUSCH transmissions before a preset number of subframes. In this embodiment, the downlink control information may be transmitted in a PDCCH or an EPDCCH, and a subframe location where the downlink control information is located may be formulated in a standard (for example, the downlink control information is sent in the PDCCH or EPDCCH in the nth or last downlink subframe according to a read C-PDCCH) or indicated by uplink control information.
