Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the use of "and/or" in the specification and claims to indicate at least one of the connected objects, such as A and/or B, means including A alone, B alone, and A and B.

In the embodiments of the present invention, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present invention should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

The following describes an embodiment of the present invention in conjunction with the accompanying drawings. The resource scheduling method provided in the embodiment of the present invention can be applied to a wireless communication system. The wireless communication system can be a 5G system, or an evolved long term evolution (eLTE) system, or a subsequent evolution communication system. The communication device can be a terminal or a network side device.

FIG1 is a structural diagram of a resource scheduling system provided by an embodiment of the present invention. As shown in FIG1 , the system includes a terminal 11 and a network side device 12, wherein the terminal 11 may be a mobile communication device, for example, a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a personal digital assistant (PDA for short), a mobile Internet device (Mobile Internet Device, MID) or a wearable device (Wearable Device), etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiment of the present invention. The above-mentioned network side device 12 may be a 5G network side device (for example, gNB, 5G NR NB), or may be a 4G network side device (for example, eNB), or may be a 3G network side device (for example, NB), or a network side device in a subsequent evolution communication system, etc. It should be noted that the specific type of the network side device 12 is not limited in the embodiment of the present invention.

In future communication systems, unlicensed bands can serve as a supplement to licensed bands to help operators expand their services. The bandwidth of unlicensed bands is generally large, for example, 80MHz or 100MHz. The large bandwidth of unlicensed bands can reduce the implementation complexity of network-side devices and terminals. Since unlicensed bands are shared by multiple communication technologies, such as WiFi (Wireless-Fidelity), radar, LTE (Long Term Evolution)-LAA (License Assisted Access), etc. Therefore, when using unlicensed bands, corresponding rules must be followed to ensure that all devices can use the resources fairly, such as LBT, MCOT (Maximum Channel Occupancy Time) and other rules.

In the scenario of using unlicensed frequency bands, the network side device needs to first perform channel sensing to determine whether the channel is idle. If the channel is idle, the network side device can send scheduling signaling to the terminal. Correspondingly, after receiving the DCI (Downlink Control Information) sent by the network side device, the terminal also needs to first perform channel sensing to determine whether the channel is idle. If the channel is idle, the terminal may send uplink data or control information.

At present, in a scheduling, the uplink resource authorized by the network side equipment to the terminal for channel monitoring is generally a time domain resource, for example, a slot. If the terminal detects that the channel is busy, data transmission will not be possible, and the network side equipment will not be able to obtain the scheduled uplink transmission data information, which makes the transmission reliability poor and the transmission efficiency low, affecting the performance of communication services.

In order to solve the above problems, an embodiment of the present invention provides a resource scheduling system as shown in FIG1 , and provides a resource scheduling method applied to the resource scheduling system, as follows:

The network side device sends a scheduling signaling to the terminal, where the scheduling signaling is used to authorize the terminal to perform channel monitoring on the uplink resources;

The terminal receives the scheduling signaling sent by the network side device;

The terminal monitors a channel on the uplink resource;

The uplink resources include N time domain resources, where N is an integer greater than 1.

In the embodiment of the present invention, since the network side device can authorize the terminal to perform continuous channel monitoring on a continuous uplink resource, the probability of successful channel monitoring by the terminal is increased, thereby improving transmission efficiency and transmission reliability and enhancing communication service performance.

FIG2 is a flow chart of a resource scheduling method provided by an embodiment of the present invention. As shown in FIG2, the resource scheduling method is applied to a terminal, and the method includes the following steps:

Step 201: Receive scheduling signaling sent by a network-side device.

The above scheduling signaling is used to authorize the terminal to perform channel monitoring on uplink resources.

The uplink resources are resources of an unlicensed frequency band, and the uplink resources may include N time domain resources, where N is an integer greater than 1. In addition to the N time domain resources, the uplink resources may also include frequency domain resources and/or space domain resources, and the embodiment of the present invention does not limit the allocation of frequency domain resources and space domain resources.

The above-mentioned uplink resources can also be understood as uplink authorization resources, that is, uplink resources authorized to the terminal to perform channel monitoring.

The length of the N time domain resources of the uplink resource in the time domain can be understood as the time domain length of the uplink resource. For example, the N time domain resources are N slots, or the N time domain resources are N symbols.

The time domain length of the uplink resource may be a fixed time domain length, which may be predefined or configured by a network side device. The time domain length of the uplink resource may also be a non-fixed time domain length, and the specific time domain length may be configured or indicated by a network side device.

At least one of the starting time domain position, the ending time domain position, and the time domain length of the uplink resource may be indicated by the scheduling signaling sent by the network side device in step 201. If the time domain length of the uplink resource is a fixed value, then when the starting time domain position of the uplink resource is indicated, the ending time domain position of the uplink resource may not be indicated; or, when the ending time domain position of the uplink resource is indicated, the starting time domain position of the uplink resource may not be indicated. When the starting time domain position and the ending time domain position of the uplink resource are indicated, the time domain length of the uplink resource may not be indicated.

It should be noted that the time domain length of the above-mentioned uplink resources generally follows the MCOT rule. If the time domain length of the uplink resources authorized by the network side device is greater than the time domain length specified in the MCOT rule, the time domain length specified in the MCOT rule can be used as the actual time domain length.

In this step, the terminal is authorized by the network side device to perform continuous channel sensing on a continuous uplink resource, so that the probability of successful channel sensing by the terminal is increased.

Step 202: Listen to a channel on an uplink resource.

In this step, since the uplink resource includes N time domain resources, the terminal can perform continuous channel sensing during the authorization period of the uplink resource, thereby improving the probability of successful channel sensing.

In the embodiment of the present invention, since the network side device can authorize the terminal to perform continuous channel monitoring on a continuous uplink resource, the probability of successful channel monitoring by the terminal is increased, thereby improving transmission efficiency and transmission reliability and enhancing communication service performance.

In the embodiment of the present invention, since the uplink resource includes N time domain resources, the terminal may monitor the channel on the uplink resource in the following manner: start channel monitoring from the first time domain resource of the uplink resource until the channel is idle. For example, the uplink resource includes 10 slots, and the terminal may start channel monitoring from the first slot, and when the channel is not idle in the first slot, continue channel monitoring in the second slot until the channel is idle.

In the embodiment of the present invention, for step 201, the channel sensing results of the terminal include the following three types: first, the terminal performs uplink transmission as long as it senses that the channel is idle on the uplink resources; second, the terminal abandons channel sensing and uplink transmission when the remaining time domain resources of the uplink resources do not meet the uplink transmission requirements based on the total time domain length required for the uplink transmission; third, the terminal does not sense that the channel is idle on any of the N time domain resources of the uplink resources.

The first and second channel sensing results are described in detail below in conjunction with FIG. 3 and FIG. 4 , respectively.

Fig. 3 is a flow chart of another resource scheduling method provided by an embodiment of the present invention. As shown in Fig. 3, the resource scheduling method is applied to a terminal, and the method comprises the following steps:

Step 301: Receive scheduling signaling sent by a network-side device.

Step 302: Listen to a channel on an uplink resource.

Step 303: When the channel is detected to be idle, uplink transmission is performed.

Among them, step 301 and step 302 can refer to the relevant description of the aforementioned step 201 and step 202, and to avoid repetition, they are not described in detail.

Optionally, the step of performing uplink transmission includes:

According to the HARQ RV order, uplink transmission starts from the target RV.

Among them, HARQ is: Hybrid automatic repeat request, hybrid automatic repeat request; RV is: Redundancy Version, redundancy version.

The target RV may be the first RV in the HARQ RV sequence, that is, when the terminal senses that the channel is idle, it transmits data starting from the first RV in accordance with the HARQ RV sequence. For example, if the HARQ RV sequence is RV0, RV2, RV3, and RV1, RV0 is the first RV in the HARQ RV sequence. When the terminal senses that the channel is idle, it may start data transmission from RV0, and after RV0 data transmission is completed, it may transmit data from RV2, and so on.

The HARQ RV sequence may establish a corresponding relationship with the N time domain resources of the uplink resources, so that the target RV may be the RV corresponding to the time domain resource detected as channel idle.

In the embodiment of the present invention, the correspondence between the HARQ RV sequence and the N time domain resources of the uplink resources may include at least multiple implementation modes, which are described below by taking the HARQ RV sequence of RV0, RV2, RV3, and RV1 as an example.

Mode 1: Each RV in the HARQ RV sequence corresponds to one time domain resource of the N time domain resources. For example, the number of time domain resources is 4, the first time domain resource (eg, the first slot) transmits RV0, the second time domain resource (eg, the second slot) transmits RV2, and so on.

In this manner, assuming that the terminal detects that the channel is idle in the second time domain resource, the terminal starts data transmission from RV2, and after the RV2 data transmission is completed, the terminal performs RV3 data transmission, and so on.

Mode 2: Each RV in the HARQ RV sequence corresponds to a plurality of consecutive time domain resources of N time domain resources, that is, a plurality of consecutive time domain resources are used to transmit one RV. For example, the number of time domain resources is 8, the first time domain resource and the second time domain resource transmit RV0, the third time domain resource and the fourth time domain resource transmit RV2, and so on.

In this method, assuming that the terminal detects that the channel is idle in the third time domain resource, the terminal performs RV2 data transmission in the third and fourth time domain resources, performs RV3 data transmission in the fifth and sixth time domain resources, and so on.

Mode 3: Each RV in the HARQ RV sequence corresponds to multiple discontinuous time domain resources of N time domain resources, that is, multiple discontinuous time domain resources are used to transmit one RV. For example, the number of time domain resources is 8, the first time domain resource transmits RV0, the second time domain resource transmits RV2, the third time domain resource transmits RV3, the fourth time domain resource transmits RV1, the fifth time domain resource transmits RV0, the sixth time domain resource transmits RV2, and so on.

In this method, assuming that the terminal detects that the channel is idle in the second time domain resource, the terminal performs data transmission of RV2 in the second time domain resource, performs data transmission of RV2 in the third time domain resource, performs data transmission of RV1 in the fourth time domain resource, performs data transmission of RV0 in the fifth time domain resource, performs data transmission of RV2 in the sixth time domain resource, and so on.

The HARQ RV sequence may be predefined or configured by a network side device. The correspondence between the RV in the HARQ RV sequence and the N time domain resources of the uplink resource may be predefined or configured by a network side device.

The embodiment of the present invention may also predefine or configure the maximum number of RVs or the minimum number of RVs for uplink transmission through a network side device.

Assuming that the maximum number of RVs for uplink transmission is 3, the terminal can perform uplink transmission starting from the target RV when it detects that the channel is idle. The transmission is considered to be completed when three RVs are sent; or the transmission is considered to be completed when the minimum number of RVs is sent.

The above-mentioned HARQ RV sequence, the correspondence between the RV in the above-mentioned HARQ RV sequence and the N time domain resources of the above-mentioned uplink resources, and the maximum number of RVs or the minimum number of RVs for uplink transmission can all be indicated through the above-mentioned scheduling signaling, and can also be indicated through other indication information.

Optionally, the method further includes:

After the uplink transmission is finished, if the time domain length of the remaining resources of the uplink resources is greater than zero, the remaining uplink resources are released. In other words, after the uplink transmission is finished, if the remaining time domain length of the uplink resources is greater than zero, the remaining uplink resources are released.

When the terminal detects that the channel is idle, the time domain resources available in the above uplink resources may be greater than the time domain resources required for uplink transmission. In order to save communication resources, the terminal can release the remaining uplink resources. On the contrary, when the terminal detects that the channel is idle, the time domain resources available in the above uplink resources may be less than the time domain resources required for uplink transmission. In this case, the terminal can perform uplink transmission in the above HARQ RV order until the available time domain resources of the uplink resources are used up.

In the embodiment of the present invention, the end of uplink transmission may be determined in the following manner: when all RV transmissions in the HARQ RV sequence are completed, or when the number of RV transmissions meets the requirement, the end of uplink transmission is determined.

Among them, whether the number of RV transmissions meets the requirement can be determined according to the maximum number of RVs or the minimum number of RVs in uplink transmission.

Fig. 4 is a flow chart of another resource scheduling method provided by an embodiment of the present invention. As shown in Fig. 4, the resource scheduling method is applied to a terminal, and the method comprises the following steps:

Step 401: Receive scheduling signaling sent by a network-side device.

Step 402: Listen to a channel on an uplink resource;

Step 403: If the channel is not detected to be idle in the Mth time domain resource of the uplink resource, stop channel sensing.

Among them, step 401 and step 402 can refer to the relevant description of the aforementioned step 201 and step 202, and to avoid repetition, they are not described in detail.

Among them, the time domain length of the N-M time domain resources is smaller than the total time domain length required for uplink transmission.

In the embodiment of the present invention, the total time domain length required for uplink transmission may be determined according to the maximum number of RVs or the minimum number of RVs for uplink transmission.

In an embodiment of the present invention, the terminal can calculate the latest time point at which the channel is detected to be idle based on the time domain length of the uplink resource and the total time domain length required for the uplink transmission. For example, the time domain length of the uplink resource is 10 slots, the number of RVs for the uplink transmission is 4, i.e., RV0, RV2, RV3, RV1, and the total time domain length required for the uplink transmission is 4 slots. If the terminal detects that the channel is idle in the third slot (i.e., slot 2), the terminal occupies the time domain resources of slot 2 and thereafter, and sends RV0, RV2, RV3, and RV1; if the terminal does not detect that the channel is idle until the seventh slot (i.e., slot 6), the terminal cannot complete the transmission of all versions during the authorization period. At this time, the terminal can stop channel monitoring and abandon the uplink transmission.

Through the above method, the power consumption of the terminal in channel monitoring can be saved, and communication resources can be released to improve the performance of communication services.
