Detailed Description

The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed or inherent to such process, method, article, or apparatus. Furthermore, the use of "and/or" in the specification and claims means at least one of the connected objects, e.g., a and/or B, meaning that it includes a single a, a single B, and that there are three cases of a and B.

In embodiments of the invention, words such as "exemplary" or "such as" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "e.g." in an embodiment should not be taken as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.

For better understanding of the technical solution of the embodiment of the present invention, the following technical points are first introduced:

1. with respect to configuration Grant (Configured Grant).

In NEW Radio (NR) version 15 (Release 15 ), the base station may configure the terminal with periodic configured grant resources, on which the terminal may perform self-scheduling transmission without base station scheduling in the presence of data.

Two configurable grant are currently supported in Rel 15:

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

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

For the above two types of configured grant, if no repeated transmission is introduced in one period, only one slot (slot) or mini slot (mini slot) can be configured as a configuration grant resource (configured grant resource) at most, as shown in fig. 1.

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

2. With respect to channel idle detection.

When a fifth generation mobile communication technology (5G) system operates in an unlicensed frequency band, before transmitting information, a terminal or a network device needs to perform channel idle estimation (Clear Channel Assess, CCA)/extended channel idle estimation (extended Clear Channel Assess, eCCA) to listen to a channel, i.e., perform Energy Detection (ED), and when Energy is below a certain threshold, the channel is determined to be empty, so that transmission can be started. This contention-based access approach leads to uncertainty in the time available for the channel, since the unlicensed band is shared by multiple transmitting nodes.

The types of listen before talk (Listen Before Talk, LBT) currently explicitly available for 5G unlicensed communication systems are three:

(1) LBT type 1 (Cat 1) does not make any CCA direct transmissions, it must be possible to use in case the channel has been acquired, with transmission transitions less than 16 microseconds (us) interval;

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

(3) LBT Cat 4, channel interception of fusion random back-off is carried out, different priority parameter settings are different, and the maximum length which can be transmitted after the channel is finally obtained is also different.

3. Regarding unlicensed band uplink wideband transmission.

For unlicensed bands (e.g., 5 GHz), the granularity of LBT in the frequency domain is 20MHz, which can be considered an uplink wideband transmission if data is transmitted on band resources above 20 MHz.

For configured grant, there are three scenarios that can be categorized as uplink broadband transmission:

scene 1: the terminal is configured with multiple carriers aggregated (Carrier Aggregation, CA) with configured grant resources configured on each carrier that are the same or overlapping in time, as illustrated in fig. 3.

Scene 2: the terminal configures one carrier, and configures different configured grant on different subbands, that is, the frequency domain resource of each configured grant is in one LBT subband, as illustrated in fig. 4.

Scene 3: the terminal configures one carrier, and the configured grant frequency domain resource includes a plurality of LBT subbands, as illustrated in fig. 5.

In scenario 1, each carrier has an independent hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) entity (entity), and no retransmission across HARQ entities, i.e. across carrier elements (Component Carrier, CC), is currently supported, and the MAC layer of the terminal is responsible for scheduling each carrier. Only one carrier, i.e. one HARQ entity, is in scenario 2 and scenario 3, and thus retransmissions on different subbands can be supported.

The techniques described herein are not limited to 5G systems and subsequent evolution communication systems, and are not limited to LTE/LTE evolution (LTE-Advanced, LTE-a) systems, and may also be used for various wireless communication systems such as code division multiple access (Code Division Multiple Access, CDMA), time division multiple access (Time Division Multiple Access, TDMA), frequency division multiple access (Frequency Division Multiple Access, FDMA), orthogonal frequency division multiple access (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. A CDMA system may implement radio technologies such as CDMA2000, universal terrestrial radio access (Universal Terrestrial Radio Access, UTRA), and the like. UTRA includes wideband CDMA (Wideband Code Division Multiple Access, WCDMA) and other CDMA variants. TDMA systems may implement radio technologies such as the global system for mobile communications (Global System for Mobile Communication, GSM). OFDMA systems may implement radio technologies such as ultra mobile broadband (Ultra Mobile Broadband, UMB), evolved UTRA (E-UTRA), IEEE 802.11 ((Wi-Fi)), IEEE 802.16 ((WiMAX)), IEEE 802.20, flash-OFDM, etc. UTRA and E-UTRA are parts of the universal mobile telecommunications system (Universal Mobile Telecommunications System, UMTS). LTE and higher LTE (e.g., LTE-a) are new UMTS releases that use E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-a and GSM are described in the literature from an organization named "third generation partnership project" (3rd Generation Partnership Project,3GPP). CDMA2000 and UMB are described in the literature from an organization named "third generation partnership project 2" (3 GPP 2). The techniques described herein may be used for the systems and radio technologies mentioned above as well as for other systems and radio technologies.

Referring to fig. 7, an embodiment of the present invention provides a scheduling method, which includes the following specific steps: step 701 and step 702.

Step 701: the MAC layer of the terminal obtains first information of PHY, wherein the first information can be information related to LBT;

step 702: and the MAC layer of the terminal performs scheduling according to the first information.

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

(1) Subband information for successful LBT;

(2) Information of channel occupancy time (Channel Occupancy Time, COT).

In the embodiment of the present invention, optionally, the subband information for successful LBT includes: sub-band information that LBT succeeds at a certain point in time; or subband information in which LBT is successful in a preset period.

Illustratively, the PHY reports subband information for each LBT success and corresponding information for the remaining COTs to the MAC layer for scheduling. It is understood that the information of the COT is optional information.

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

For example, the MAC layer may evaluate the result of the LBT success reported multiple times on each sub-band, determine the idle condition on the sub-band according to the evaluation result, and schedule according to the idle condition, for example: the result of multiple reports of LBT success may be a proportion of the subband LBT success over a time window.

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

the MAC layer of the terminal schedules on a target sub-band according to the first information and the idle information of the sub-band, wherein the target sub-band is a sub-band with channel conditions superior to a preset threshold value, and the first information does not comprise: subband information that LBT was successful at a certain point in time.

For example, the channel condition may be a ratio of successful sub-bands LBT, the preset threshold corresponds to a preset ratio threshold of successful sub-bands LBT, for example, the ratio of successful sub-bands LBT of the first sub-band is 8/10, "10" indicates the total number of successful sub-bands LBT of the first sub-band, "8" indicates the number of successful sub-bands LBT of the first sub-band, the ratio of successful sub-bands LBT of the second sub-band is 5/10, "10" indicates the total number of successful sub-bands LBT of the second sub-band, "5" indicates the number of successful sub-bands LBT of the second sub-band, and the preset ratio threshold of successful sub-bands LBT of the first sub-band is 7/10.

the MAC layer of the terminal performs scheduling on a target sub-band according to the first information, wherein the target sub-band is all sub-bands or any one or more sub-bands; wherein the first information does not include: subband information that LBT was successful at a certain point in time. It is understood that any one or more of the sub-bands is a randomly selected one or more of the sub-bands.

Illustratively, the MAC layer performs initial scheduling when there is a data transmission and no subband information that LBT succeeds at a certain point in time is received, specifically as follows:

if the MAC layer has long-term idle status statistics information (corresponding to idle information of the sub-band), the MAC layer may select a sub-band with better channel status of the sub-band to schedule, for example, the successful rate of the sub-band LBT in the previous time window is greater than a threshold value; otherwise, the MAC layer schedules on all sub-bands or on randomly selected sub-bands.

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

(1) The MAC layer of the terminal will not schedule on carrier units (Component Carrier, CC) failed in LBT in the subsequent time slot (slot) of receiving the sub-band information successful in LBT at a certain time point;

(2) The MAC layer of the terminal will not schedule on the sub-band where the LBT failed at a certain time point, and/or schedule the data scheduled on the sub-band where the LBT failed on the subsequent slot where the sub-band information where the LBT succeeds is received.

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

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

(1) For scenario 1, the mac layer will not schedule on CCs that fail LBT on subsequent slots that receive LBT success information at some point in time, as shown in fig. 9, CC2 and CC3 are no longer scheduled on slots #2 and # 3. Meanwhile, cross HARQ transmission is not supported, and the data prepared on slot #1 needs to be transmitted on the CC corresponding to the configured grant of the next period;

(2) For scenario 2, the mac layer will not schedule on the sub-band where LBT fails at a certain point in time when the subsequent slot receives LBT success information, while data prepared on other sub-bands may be transmitted on the sub-band where LBT is successful, as shown in fig. 10, BWP (Band Width Part) is a bandwidth part.

(3) For scenario 3, the mac layer will update FDRA information through UCI at a subsequent slot where LBT success information is received at a certain point in time, wherein the updated FDRA information no longer includes the sub-band for which LBT failed, as shown in fig. 11.

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

according to the information of COT, the MAC layer of the terminal does not schedule the first slot after the COT is finished, and can reserve time for LBT for the subsequent slot.

Referring to fig. 8, the embodiment of the present invention further provides a reporting method, which specifically includes the steps of: step 801.

Step 801: the PHY of the terminal reports first information to the MAC layer, wherein the first information is information related to LBT, and the first information is used for scheduling by the MAC layer of the terminal.

(1) Subband information for successful LBT;

(2) Information of channel occupancy time (Channel Occupancy Time, COT).

In the embodiment of the present invention, optionally, the subband information for successful LBT includes: sub-band information successful at a time point LBT; or subband information in which LBT is successful in a preset period.

Illustratively, each time the PHY performs LBT successful sub-band information and corresponding remaining COT information is reported to the MAC layer for scheduling use. It is understood that the information of the COT is selectable.

In the embodiment of the invention, the PHY reports the first information to the MAC layer, so that the MAC layer can schedule according to the first information, and thus, the MAC layer can fully utilize transmission resources of an unlicensed frequency band, and the reliability and efficiency of data transmission are improved.

The embodiment of the invention also provides a terminal, and the principle of solving the problem of the terminal is similar to that of the scheduling method in the embodiment of the invention, so that the implementation of the terminal can be referred to the implementation of the method, and the repetition is not repeated.
