Detailed ways

In order to facilitate the understanding of the embodiments of the present disclosure, the following contents are first explained.

Unlicensed bands (unlicensed bands) can be used as a supplement to licensed bands (licensed bands) to help operators expand their services. In order to be consistent with the deployment of New Radio (NR) and maximize NR-based unlicensed access as much as possible, unlicensed frequency bands can work in 5GHz, 37GHz and 60GHz frequency bands. The large bandwidth (80MHz or 100MHz) of the unlicensed frequency band can reduce the implementation complexity of the base station and UE. Since unlicensed frequency bands are shared by multiple technologies (RATs), such as WiFi, radar, LTE-LAA, etc., in some countries or regions, unlicensed frequency bands must be used in compliance with regulations to ensure that all devices are fair The use of this resource, such as LBT (listen before talk), maximum channel occupation time (Maximum Channel Occupancy Time, MCOT) and other rules. When the transmission node needs to send information, it needs to perform LBT first, and perform energy detection (ED) on surrounding nodes. When the detected power is lower than a threshold, the channel is considered to be idle and the transmission node can perform send. Otherwise, the channel is considered to be busy and the transmitting node cannot send. The transmission node may be a base station, UE, WiFi access point (Access Point, AP), and so on. After the transmission node starts transmission, the occupied channel time COT cannot exceed MCOT.

Among them, the type of LBT (category) can be divided into category 1, category 2, and category 4. Category1LBT means that the transmission node does not do LBT, that is, no LBT or immediate transmission. Category 2 LBT is one-shot LBT, that is, the transmission node performs LBT once before transmission, and the channel is empty for transmission, and the channel is busy without transmission. Category 4 LBT is a back-off-based channel listening mechanism. When the transmission node detects that the channel is busy, it performs a back-off and continues to listen until it hears that the channel is empty. Category 4 LBT contains multiple priority levels, and for each priority level, the maximum channel occupation time is different. As shown in Table 1 and Table 2 below.

Table 1 Channel Access Priority Class

Table 2 Uplink channel access priority

Among them, T _mcot,p in Table 1 above represents the maximum channel occupation time of downlink transmission of corresponding priority p. _{T ulmcot,p} in Table 2 above represents the maximum channel occupation time of uplink transmission of corresponding priority p. m _p represents the coefficient corresponding to the corresponding priority p. CW _p represents the value of the contention window corresponding to the corresponding priority p. CW _min,p represents the minimum value of the contention window corresponding to the corresponding priority p. CW _max,p represents the maximum value of the contention window corresponding to the corresponding priority p.

Various different types of physical random access channel (PRACH) preamble format (PRACH preamble format) are defined in NR. Different formats correspond to different preamble sequence lengths, interval CP lengths, and time domain lengths. And so on, to adapt to different coverage areas. Among them, the total duration of PRACH in various formats is different. For each PRACH preamble format, the corresponding channel access priority can be agreed upon. For each cell, the network can configure a PRACH preamble format, 64 preamble sequences, 64 preambles corresponding to different cyclic shift values, and the same or different root sequence number values.

The wireless communication system of the embodiment of the present disclosure includes a terminal and a network device. Among them, the terminal can also be called a terminal device or a user terminal (User Equipment, UE), and the terminal can be a mobile phone, a tablet (Personal Computer), a laptop (Laptop Computer), a personal digital assistant (Personal Digital Assistant, PDA). ), Mobile Internet Device (MID), Wearable Device (Wearable Device), or in-vehicle device and other terminal-side devices. It should be noted that the specific types of terminals are not limited in the embodiments of the present disclosure. The network equipment may be a base station or a core network, where the above-mentioned base station may be a base station of 5G and later versions (for example: gNB, 5G NR NB, etc.), or a base station in other communication systems (for example: eNB, WLAN access point, or Other access points, etc.), the base station can be called Node B, Evolved Node B, Access Point, Base Transceiver Station (BTS), Radio Base Station, Radio Transceiver, Basic Service Set, BSS), Extended Service Set (ESS), Node B, Evolved Node B (eNB), Home Node B, Home Evolved Node B, WLAN Access Point, WiFi Node, or any other in the field Appropriate terms, as long as they achieve the same technical effect, are not limited to specific technical vocabulary.

Please refer to FIG. 1. FIG. 1 is a flowchart of a resource sharing method provided by an embodiment of the present disclosure. The method is applied to a terminal. As shown in FIG. 1, the method includes the following steps:

Step 101: Select a random access resource.

In this embodiment, the random access resource is used to indicate whether the network device is allowed to share the channel occupation time (Channel Occupancy Time, COT) of the terminal. Specifically, the random access resource is used to implicitly indicate whether the network device is allowed to share the COT of the terminal.

Optionally, the process for the terminal to select random access resources may be: first, determine whether the network device is allowed to share its own COT, and obtain a determination result; wherein, the determination result may be that the network device is allowed to share its own COT or the network device is not allowed Share its own COT; then, select the random access resource corresponding to this determination result, which implicitly indicates whether the network device is allowed or not allowed to share the COT of the terminal. After selecting the random access resource, the terminal can perform random access according to the random access resource.

Optionally, the foregoing random access resource may include any one of the following: a random access preamble (preamble), a random access opportunity (RACH occasion, RO), and the like.

In the resource sharing method of the embodiment of the present disclosure, the selected random access resource is used to indicate whether the network device is allowed to share the COT of the terminal, so that the terminal can implicitly indicate whether to perform COT sharing by using different resources, so that the terminal performing random access can Share your own COT with network equipment, thereby reducing the time delay for network equipment to send information and improving the efficiency of random access.

In the embodiments of the present disclosure, in order to enable the selected random access resource to indicate (implicitly) allow or not allow the network device to share the COT of the terminal, the random access resource can be grouped, and different groups of resources can be selected to indicate whether Perform COT sharing.

Optionally, when the random access resources are grouped, they can be divided into two resource groups, namely the first resource group and the second resource group, which respectively indicate the COT of allowing network devices to share terminals and the non-allowing network devices to share terminals. COT. In this way, when the random access resource belongs to the first resource group, it can indicate that the network device is allowed to share the COT of the terminal; or when the random access resource belongs to the second resource group, it can indicate that the network device is not allowed to share the terminal. COT.

Understandably, the "first" and "second" in the above-mentioned first resource group and the second resource group are used to distinguish resource groups and have no specific meaning. The first resource group can also be used under appropriate circumstances. It means that the network device is not allowed to share the COT of the terminal, and the second resource group indicates that the network device is allowed to share the COT of the terminal.

In an implementation manner, taking the random access resource as the preamble as an example, the preamble can be divided into two groups, namely preamble group 1 and preamble group 2, where preamble group 1 indicates that the UE allows gNB to share its own COT, and preamble group 2 Indicates that the UE does not allow gNB to share its own COT. The UE implicitly indicates whether the gNB is allowed to share the COT of the UE by selecting preambles in different groups. In this way, when the gNB detects that the UE uses the preamble in the preamble group 2, the gNB does not share the COT of the UE. When the gNB detects that the UE uses the preamble in the preamble group 1, the gNB can share the COT of the UE according to the agreement and send downlink data.

In another embodiment, taking the random access resource as the RO as an example, the RO can be divided into two groups, namely RO group 1 and RO group 2, where RO group 1 indicates that the UE allows gNB to share its COT, and the RO group 2 means that the UE does not allow gNB to share its own COT. The UE implicitly indicates whether the gNB is allowed to share the COT of the UE by selecting ROs in different groups. In this way, when the gNB detects that the UE uses the RO in the RO group 2, the gNB does not share the COT of the UE. When the gNB detects that the UE uses the RO in the RO group 1, the gNB can share the COT of the UE according to the agreement and send downlink data.

Optionally, in the case where the aforementioned random access resource includes a random access preamble (preamble), different resource groups can be distinguished by any one of the following:

Different random access preamble indexes;

Different cyclic shift values;

Different root sequence numbers.

Optionally, the grouping method of the foregoing resource groups may be determined according to any one of the following:

1) Pre-defined rules

Under this 1), the grouping method can be implicitly determined.

For example, taking the preamble as an example, a preamble with an odd sequence number can be predefined to correspond to a resource group, which means that COT sharing is allowed, and a preamble with an even sequence number corresponds to another resource group, which means that COT sharing is not allowed; alternatively, pre-defined X( X is an integer greater than 0) preambles correspond to one resource group, which means that COT sharing is allowed, while the last 64-X preambles correspond to another resource group, which means that COT sharing is not allowed.

For another example, taking the RO as an example, an odd-numbered RO can be predefined to correspond to a resource group, which means that COT sharing is allowed, while an even-numbered RO corresponds to another resource group, which means that COT sharing is not allowed. In this way, if the gNB detects the PRACH on the odd-numbered RO, it is considered that the COT of the UE can be shared; or, if the gNB detects the PRACH on the even-numbered RO, it is considered that the COT of the UE cannot be shared.

2) Instructions for network equipment

Under this 2), the grouping method can be explicitly determined.

For example, taking the preamble as an example, the network devices can respectively indicate whether the preamble set corresponding to the COT can be shared.

For another example, taking the RO as an example, the gNB can explicitly configure which PRACH preambles sent on the RO implicitly indicate that the gNB can share the COT of the UE, and which PRACH preambles sent on the RO implicitly indicate that the gNB cannot share the COT of the UE.

In the embodiment of the present disclosure, when the terminal shares its remaining COT with the network device, since the terminal cannot explicitly send COT related information to the network device, such as the priority class of the terminal for LBT and the COT of the terminal The remaining time (remaining COT), the end time of the COT of the terminal, etc., can therefore implicitly indicate the aforementioned COT related information through the configured PRACH (Physical Random Access Channel, physical random access channel) preamble format (PRACH preamble format). Specifically, it can be agreed that each PRACH preamble format corresponds to a channel access priority (priority class value), and this priority is the highest priority allowed to be used by a terminal configured with the PRACH preamble format. That is to say, for each PRACH preamble format, the protocol stipulates the highest priority for the corresponding channel access. The channel access priority selected by the terminal during random access cannot be higher than the highest priority of channel access corresponding to the configured PRACH preamble format, so that the network device can obtain COT related information.

Optionally, during random access, the terminal in the embodiment of the present disclosure may use the corresponding channel access priority to listen to the channel according to the configured PRACH preamble format, and when the channel is empty, , For random access.

For example, for PRACH preamble format 1 or PRACH preamble format 2, the highest priority for channel access allowed by the UE is priority class 2; for other PRACH preamble formats, the highest priority for channel access allowed by the UE is priority class 1. Therefore, during random access, if the UE is configured with PRACH preamble format 1 or PRACH preamble format 2, the priority class 2, 3, or 4 can be adopted; or, if other PRACH preamble formats are configured, the priority can be adopted. The priority is priority class 1, 2, 3, or 4.

Please refer to FIG. 2. FIG. 2 is a flowchart of a resource sharing method provided by an embodiment of the present disclosure. The method is applied to a network device. As shown in FIG. 2, the method includes the following steps:

Step 201: Determine whether to share the COT of the terminal according to the random access resources used by the terminal.

In this embodiment, the random access resource is used to indicate (implicitly) whether the network device is allowed to share the COT of the terminal, and is a resource selected by the terminal to use when performing random access. When the network device detects the resource used by the terminal during random access (such as initial access), it can decide whether to share the COT of the terminal based on the content implicitly indicated by the resource.

Optionally, the foregoing random access resource may include any one of the following: a random access preamble (preamble), a random access opportunity (RO), and the like.

In the resource sharing method of the embodiments of the present disclosure, the network device can determine whether to share the COT of the terminal according to the resources used by the terminal during random access, so that the network device can send information based on the shared terminal COT, thereby reducing the amount of information sent by the network device. Delay, improve the efficiency of random access.

In the embodiments of the present disclosure, in order to enable the random access resource selected by the terminal to implicitly indicate that the network device is allowed or not allowed to share the COT of the terminal, the random access resource can be grouped, and different groups of resources can be used to indicate whether to perform COT. shared.

Optionally, when the random access resources are grouped, they can be divided into two resource groups, namely the first resource group and the second resource group, which respectively indicate the COT of allowing network devices to share terminals and the non-allowing network devices to share terminals. COT. The above step 201 may include:

In the case that the random access resource belongs to the first resource group, determining to share the COT of the terminal;

Or, in a case where the random access resource belongs to the second resource group, it is determined not to share the COT of the terminal.

Optionally, in the case of determining the COT of the shared terminal, the COT duration of the terminal shared by the network device may be a fixed duration, for example, the fixed duration may be agreed upon by a protocol; or, the maximum channel occupancy time of the terminal (Maximum Channel Occupancy Time) Time, MCOT) decision, where the sum of the COT duration of the terminal shared by the network device and the PRACH transmission duration of the terminal is less than or equal to (that is, does not exceed) the duration of the MCOT; for example, the MCOT can be agreed upon by an agreement.

For example, in the future enhanced authorized assisted access (Further enhanced Licensed Access, FeLAA) autonomous uplink (Autonomous Uplink, AUL), the COT duration of the UE that can be shared by the eNB does not exceed 2 symbols. In NR-U, the fixed duration of the COT of the UE shared by the gNB can be agreed upon by agreement.

Optionally, in the case where the terminal MCOT is determined, the COT duration of the terminal shared by the network device may be determined by the MCOT obtained according to the highest priority of channel access corresponding to the PRACH preamble format of the terminal For example, it may be determined by the minimum MCOT (minimum MCOT) obtained according to the highest priority, that is, the sum of the transmission duration of the terminal and the duration that can be shared by the network device does not exceed the minimum MCOT duration.

Among them, the highest priority of channel access corresponding to the PRACH preamble format may be agreed upon by the protocol. That is, in the embodiments of the present disclosure, for each PRACH preamble format, the highest priority of the corresponding channel access can be agreed upon by agreement.

In one implementation, it is assumed that the gNB configures PRACH preamble format1 for the UE, and the protocol stipulates that the highest priority of channel access corresponding to this PRACH preamble format1 is priority class 2, and the channel access priority based on the uplink UL in the related technology The class table is shown in Table 2 above. The MCOT corresponding to this priority class 2 is 4ms, that is, the smallest MCOT is 4ms. At this time, even if the UE selects priority class 3 for channel access, the MCOT corresponding to priority class 3 is 6 ms, and the sum of the UE transmission duration and the COT duration of the UE that can be shared by the gNB is also set at 4 ms as the upper limit. That is, the duration of the COT of the UE shared by the gNB is determined based on 4ms, which is equal to 4ms minus the duration of the corresponding PRACH. In this way, it can be guaranteed that the sum of the transmission time of the UE and the transmission time of the gNB (shared by the UE) will never exceed the MCOT of the UE.

In the embodiments of the present disclosure, when the COT of the terminal is shared by the network equipment, an uplink-downlink conversion occurs in the COT of the terminal, that is, the initial uplink transmission is converted to the downlink transmission. In order to meet the requirements of the uplink and downlink conversion in the COT, the gap between the end time of the downlink transmission and the start time of the uplink transmission can be agreed upon by the protocol. For example, the gap can be selected to be less than 16 us, equal to 16 us, or approximately equal to 25 us.

Optionally, in the case of determining the COT of the shared terminal, the LBT type adopted by the network device in the shared COT may be any one of the following: type 1, type 2.

Among them, the category 1 (category 1) is direct transmission (immediate transmission), that is, no LBT (no LBT). This category 2 (category 2) is a one-shot LBT (one-shot LBT), and can be selected as a type 2 with a preset duration, such as 16us LBT or 25us LBT.

Optionally, the LBT type adopted by the aforementioned network equipment in the shared COT may be determined according to any one of the following:

Agreement

COT implicit indication;

The PRACH preamble format is implicitly indicated.

For example, suppose that the UE is configured with PRACH preamble format1, and the PRACH preamble format1 implicitly indicates that the LBT type adopted by the network device is type 1. Or, suppose that the UE is configured with PRACH preamble format2, and the PRACH preamble format2 implicitly indicates that the LBT type adopted by the network device is 16us LBT.
