detailed description

The technical solutions in the embodiments of the present disclosure will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present disclosure.

The term "comprising" in the specification and claims of this application and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to clear Instead, those steps or units listed below may include other steps or units that are not clearly listed or are inherent to these processes, methods, products, or equipment. In addition, the use of "and/or" in the specification and claims means at least one of the connected objects, such as A and/or B, which means that A and B alone are included, and there are three cases for both A and B.

In the embodiments of the present disclosure, words such as "exemplary" or "for example" are used as examples, illustrations, or illustrations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present disclosure should not be construed as being more preferable or advantageous than other embodiments or design solutions. To be precise, words such as "exemplary" or "for example" are used to present related concepts in a specific manner.

In order to better understand the technical solutions of the embodiments of the present disclosure, first introduce the following technical points:

1. Regarding Configured Grant.

In the new radio (NEW Radio, NR) version 15 (Release 15, Rel15), the base station can configure the terminal with periodic configured grant resources. On these resources, the terminal can schedule itself without base station scheduling when there is data. send.

Currently, two configured grants are supported in Rel15:

(1) Type 1 (Type 1): Radio Resource Control (Radio Resource Control, RRC) configures all parameters, including: period, power control, time-frequency resource allocation, time offset, and modulation coding strategy (Modulation Coding Scheme, MCS) etc.;

(2) Type 2: RRC configuration period, power control and other parameters, Downlink Control Information (DCI) to activate configured grant resources, time-frequency resource allocation and MCS are both given by DCI.

For the above two types of configured grants, if repeated transmissions are not introduced in a cycle, only one slot or mini slot can be configured as a configured grant resource, as shown in Figure 1. Shown.

In the discussion of NR version 16 (Release 16, Rel16), for the same terminal, multiple active configured grants can be configured, so resource configuration can be more flexible. The configured grant resources configured as shown in Figure 2 can span Multiple slots and multiple subbands.

2. Regarding channel idle detection.

When the fifth-generation mobile communication technology (fifth-generation, 5G) system is running in an unlicensed frequency band, the terminal or network device needs to perform a clear channel assessment (CCA)/extended channel clear assessment before sending information Clear Channel Assess (eCCA) to listen to the channel, that is, to perform energy detection (Energy Detection, ED). When the energy is below a certain threshold, the channel is judged to be empty before transmission can begin. Since the unlicensed frequency band is shared by multiple transmission nodes, this contention-based access method leads to uncertainty in channel available time.

Currently, there are three types of Listen Before Talk (LBT) that are clearly applicable to 5G unlicensed communication systems:

(1) LBT Type 1 (Cat 1): Direct transmission without any CCA. It must be used when the channel has been obtained and the transmission conversion interval is less than 16 microseconds (us);

(2) LBT Cat 2: Perform 25us channel listening, which can be used for specific signal acquisition channels, and the maximum continuous transmission length should be less than a certain value, for example: 1 millisecond (ms);

(3) LBT Cat 4: Channel listening with fusion random backoff. Different priority parameters are set differently, and the maximum transmission length after obtaining the channel is also different.

3. Regarding uplink broadband transmission in unlicensed frequency bands.

For an unlicensed frequency band (for example, 5 GHz), the granularity of LBT in the frequency domain is 20 MHz. If data is transmitted on frequency band resources greater than 20 MHz, it can be regarded as uplink broadband transmission.

For the configured grant, the following three scenarios can be classified as uplink broadband transmission:

Scenario 1: The terminal is configured with multiple carrier aggregation (Carrier Aggregation, CA) carriers, and the configured grant resources configured on each carrier are the same in time or have overlapping parts, as shown in the example in Figure 3.

Scenario 2: The terminal configures a carrier and configures different configured grants on different subbands, that is, the frequency domain resources of each configured grant are in one LBT subband, as shown in the example in Figure 4.

Scenario 3: The terminal configures a carrier, and the configured frequency domain resource of the configured grant includes multiple LBT subbands, as shown in Figure 5.

In scenario 1, each carrier has an independent hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) entity, and currently does not support cross-HARQ entity, that is, cross-carrier unit (Component Carrier, CC) retransmission , The MAC layer of the terminal is responsible for the scheduling of each carrier. In both scenario 2 and scenario 3, there is only one carrier, that is, one HARQ entity, so retransmissions on different subbands can be supported.

The technology described herein is not limited to 5G systems and subsequent evolved communication systems, and is not limited to LTE/LTE evolution (LTE-Advanced, LTE-A) systems, and can also be used in various wireless communication systems, such as code division multiple access ( Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single Carrier Frequency Division Multiple Access (Single-carrier Frequency-Division Multiple Access, SC-FDMA) and other systems.

The terms "system" and "network" are often used interchangeably. The CDMA system can implement radio technologies such as CDMA2000 and Universal Terrestrial Radio Access (UTRA). UTRA includes Wideband Code Division Multiple Access (WCDMA) and other CDMA variants. The TDMA system can implement radio technologies such as the Global System for Mobile Communication (GSM). OFDMA system can realize such as ultra mobile broadband (Ultra Mobile Broadband, UMB), evolved UTRA ((Evolution-UTRA, E-UTRA)), IEEE 802.11 ((Wi-Fi)), IEEE802.16 ((WiMAX)), Radio technologies such as IEEE 802.20 and Flash-OFDM. UTRA and E-UTRA are part of Universal Mobile Telecommunications System (UMTS). LTE and more advanced LTE (such as LTE-A) are new UMTS versions that use E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A, and GSM are described in documents from an organization named "3rd Generation Partnership Project" (3GPP). CDMA2000 and UMB are described in documents from an organization named "3rd Generation Partnership Project 2" (3GPP2). The technology described in this article can be used for the systems and radio technologies mentioned above as well as other systems and radio technologies.

Referring to FIG. 7, an embodiment of the present disclosure provides a scheduling method, and specific steps include: step 701 and step 702.

Step 701: The MAC layer of the terminal obtains first information of the PHY, where the first information may be information related to LBT;

Step 702: The MAC layer of the terminal performs scheduling according to the first information.

In the embodiment of the present disclosure, optionally, the first information may include one or more of the following:

(1) The sub-band information of LBT success;

(2) Channel Occupancy Time (COT) information.

In the embodiment of the present disclosure, optionally, the sub-band information of LBT success includes: the sub-band information of LBT success at a certain point in time; or the sub-band information of LBT success in a preset time period.

Exemplarily, the PHY reports the subband information for each successful LBT and the corresponding remaining COT information to the MAC layer for scheduling. It is understandable that the COT information is optional.

Further, the sub-band information of successful LBT within the preset time period may be: the proportion of successful LBT of the sub-band within the preset time period. The preset time period may also be referred to as a preset time window. It is understandable that the value of the preset time period is not specifically limited in the embodiment of the present disclosure.

Exemplarily, the MAC layer can evaluate the results of multiple successful LBT reports on each sub-band, determine the idle status of the sub-band based on the evaluation results, and then schedule according to the idle conditions, for example: report the successful results of LBT multiple times It can be the percentage of successful LBT of the sub-band within a time window.

In the embodiment of the present disclosure, optionally, the MAC layer of the terminal performs scheduling according to the first information, which may include:

The MAC layer of the terminal performs scheduling on the target subband according to the first information and the idle information of the subband, where the target subband is a subband whose channel condition is better than a preset threshold, and the first information does not include: Information about the sub-bands of successful LBT at a certain point in time.

Exemplarily, the channel condition may be the percentage of successful LBT sub-bands, and the preset threshold is equivalent to the preset percentage threshold of successful LBT sub-bands. For example, the first sub-band LBT success percentage is 8/10 , "10" indicates the total number of LBTs in the first sub-band, "8" indicates the number of successful LBTs in the first sub-band, the ratio of successful LBT in the second sub-band is 5/10, and "10" indicates the LBT of the second sub-band The total number of times, "5" indicates the number of successful LBT subbands in the second sub-band, and the preset ratio threshold of successful LBT sub-bands is 7/10, and the first sub-band can be determined as the target sub-band.

It can be understood that any one or more sub-bands are randomly selected one or more sub-bands.

Exemplarily, the MAC layer performs initial scheduling when there is data transmission and the subband information that LBT succeeds at a certain point in time is not received, specifically as follows:

If the MAC layer has long-term idle status statistics information for each sub-band (equivalent to the idle information of the sub-band), the MAC layer can select the sub-band with better channel conditions for scheduling, for example, the sub-band LBT in the previous time window The proportion of success is greater than a threshold; otherwise, the MAC layer performs scheduling on all sub-bands or randomly selected several sub-bands.

In the embodiment of the present disclosure, optionally, the MAC layer of the terminal performs scheduling according to the first information, which may include at least one of the following:

(1) The MAC layer of the terminal will not perform scheduling on the component carrier (CC) where the LBT fails after receiving the sub-band information of the successful LBT at a certain point in time.

The MAC layer of the terminal will update the frequency domain resource allocation (Frequency Domain Resource Allocation, FDRA) information through the uplink control information (Uplink Control Information, UCI) after receiving the subsequent slot after the sub-band information of the successful LBT at a certain point in time; , FDRA information may not include: information about sub-bands where LBT fails.

Exemplary, when data transmission is in progress and the MAC layer has received the LBT success information at a certain point in time, subsequent scheduling is performed:

(1) For scenario 1, the MAC layer will not perform scheduling on the CC where the LBT fails after receiving the LBT success message at a certain point in time. As shown in Figure 9, CC2 and CC3 are not scheduled in slots #2 and #3. Reschedule. At the same time, because cross HARQ transmission is not supported, the data prepared on slot #1 at this time needs to be transmitted on the CC corresponding to the configured grant in the next cycle;

(2) For scenario 2, the MAC layer will not perform scheduling on the sub-band where LBT fails after receiving the LBT success information at a certain point in time, while data prepared on other sub-bands can be on the sub-band where LBT is successful. For transmission, as shown in Figure 10, BWP (Band Width Part) in the figure is the bandwidth part.

(3) For scenario 3, the MAC layer will update the FDRA information through UCI at the subsequent slot after receiving the LBT success information at a certain point in time, where the updated FDRA information no longer includes the sub-bands where the LBT fails, as shown in Figure 11.

In the embodiment of the present disclosure, optionally, the MAC layer of the terminal performs scheduling according to the first information, including:

According to the COT information, the MAC layer of the terminal does not perform scheduling in the first slot after the COT ends, and can allow time for subsequent slots to perform LBT.
