Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a data processing method, apparatus, terminal equipment, base station, and storage medium. Background Art

[0002] Currently 5G NR-U (5 th Generation new radio unlicense (GNR) systems support two methods for initializing the channel occupation time (COT): gNB (g Node B)-initialized COT and UE-initialized COT. If the gNB-initialized COT overlaps with the UE-initialized COT, and the UE-initialized COT successfully arrives earlier than the gNB-initialized COT, the gNB will be unable to initialize a COT and thus unable to schedule other UEs.

[0003] To address the conflict between gNB-initiated COTs and UE-initiated COTs when they coexist, the current approach is to use downlink control information (DCI) to indicate to the UE whether it can initiate the next COT. However, using DCI to indicate whether the next UE's fixed frame period (FFP) can initiate the next COT is problematic because the UE must frequently demodulate the DCI to determine whether a COT can be initiated, which affects UE power consumption. Summary of the Invention

[0151] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0152] It should be noted that if Figure 1 As shown, currently 5G NR-U (5 thGeneration new radio unlicense (GNR) systems support two methods for initializing the Channel Occupation Time (COT): one initiated by the gNB (gNode B) and the other by the UE (User Equipment). If the gNB-initialized COT and the UE-initialized COT overlap, and the UE successfully initializes the COT earlier than the gNB-initialized COT, the gNB will be unable to initialize a COT and thus be unable to schedule other UEs. Because the UE-initialized COT is only used for transmissions between it and the gNB (broadcast signaling, HARQ-ACK feedback for the UE, and scheduled retransmissions), other UEs cannot send uplink transmissions within the COT, resulting in reduced resource utilization and overall system throughput. Therefore, the conflict between the UE-initialized COT and the gNB-initialized COT needs to be resolved.

[0153] To address the conflict between gNB-initiated COTs and UE-initiated COTs when they coexist, the current approach is to use downlink control information (DCI) to indicate to the UE whether it can initiate the next COT. However, the problem with using DCI to indicate whether the next UE's fixed frame period (FFP) can initiate the next COT is that the UE needs to frequently demodulate the DCI to determine whether a COT can be initialized, which affects the UE's power consumption. The following is a detailed analysis:

[0154] 5G NR-U (5G New Radio in Unlicensed Spectrum) is a 5G air interface that operates in unlicensed frequency bands. This spectrum can be used without authorization from the competent authority if regulatory requirements are met.

[0155] Currently, 5G NR-U defines two types of equipment: Frame Based Equipment (FBE) and Load Based Equipment (LBE). For FBE, a channel detection is performed at a fixed location within a set period, such as during each Clear Channel Assessment (CCA) detection time. If the channel is detected as idle, the device can occupy the channel for transmission. If the channel is not idle, the device cannot occupy the channel during this period until it resumes detection at a fixed location in the next period. Performing CCA for interference detection within each period incurs significant processing overhead and compromises channel access success rates. Currently, two methods are supported for initializing the Channel Occupation Time (COT): gNB-initialized COT and UE-initialized COT. To resolve conflicts between gNB-initialized and UE-initialized COTs when they coexist, the current approach is to use Downlink Control Information (DCI) to indicate to the UE whether to initiate the next COT. However, the problem with using DCI to indicate whether the next UE's fixed frame period (FFP) can initialize the next COT is that the UE must frequently demodulate DCI to determine whether a COT can be initialized, which affects the UE's power consumption. Furthermore, if the gNB fails to successfully initialize a COT, it cannot indicate whether the UE can initialize the next COT. This can result in the UE having traffic to transmit but unable to initialize a COT and relying solely on the gNB-initialized COT. If the gNB fails to initialize the COT, the UE cannot transmit data. Furthermore, using DCI to indicate whether the UE can initialize the next COT also fails to address the issue of overlapping gNB-initialized and UE-initialized COTs. If the UE's successfully initialized COT is earlier than the gNB-initialized COT, the gNB will be unable to initialize a COT.To address this issue, an embodiment of the present application provides a data processing method. This data processing method transmits a fixed frame period FFP transmission pattern to the UE. This allows, on the one hand, the FFP transmission pattern to indicate multiple FFPs that allow UE-initialized COTs to be executed at once, thereby resolving the prior art issue of the UE's power consumption being affected by the UE's need to frequently demodulate DCI to determine whether a COT can be initialized. Furthermore, since the FFP transmission pattern can indicate the FFPs for the channel occupancy time COT that allows the UE to initialize and / or the FFPs for the COT that does not allow the UE to initialize, the conflict between the gNB-initialized COT and the UE-initialized COT can be resolved, thereby improving the resource utilization and throughput of the entire system. The data processing method, apparatus, terminal device, base station, and storage medium provided in this application will be explained and illustrated in detail below through specific embodiments.

[0156] It should be noted that in the following description, since the method and the device are based on the same application concept and the principles of solving the problem are similar, the implementation of the device and the method can refer to each other and the repeated parts will not be repeated.

[0157] In addition, it should be noted that the technical solutions provided in the embodiments of the present application can be applicable to a variety of systems, especially 5G systems. For example, applicable systems may be global system of mobile communication (GSM) systems, code division multiple access (CDMA) systems, wideband code division multiple access (WCDMA) general packet radio service (GPRS) systems, long term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, long term evolution advanced (LTE-A) systems, universal mobile telecommunication systems (UMTS), worldwide interoperability for microwave access (WiMAX) systems, 5G new air interface (NR) systems, etc. These various systems include terminal devices and network devices. The system may also include a core network part, such as an evolved packet system (EPS), a 5G system (5GS), etc.

[0158] The terminal device involved in the embodiments of the present application may be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connection function, or other processing devices connected to a wireless modem. In different systems, the name of the terminal device may also be different. For example, in a 5G system, the terminal device may be called a user equipment (UE). A wireless terminal device can communicate with one or more core networks (CN) via a radio access network (RAN). The wireless terminal device can be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device. For example, it can be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device that exchanges language and / or data with a radio access network. For example, personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), and other devices. Wireless terminal devices may also be referred to as systems, subscriber units, subscriber stations, mobile stations, mobile stations, remote stations, access points, remote terminal devices, access terminal devices, user terminal devices, user agents, and user devices, and are not limited in the embodiments of the present application. Since terminal devices and other network devices (such as core network devices and access network devices (i.e., base stations)) together constitute a network that supports communication, in the present invention, terminal devices are also considered as a type of network device.

[0159] The base station involved in the embodiments of the present application may include multiple cells providing services to the terminal, and may also be a CU (Central Unit) or a DU (Distributed Unit). Depending on the specific application scenario, it may also be called an access point, or may be a device in the access network that communicates with the wireless terminal device through one or more sectors on the air interface, or other names. The base station can be used to interchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) communication network. The network equipment can also coordinate the attribute management of the air interface.

[0160] Furthermore, it should be understood that the term "and / or" in the embodiments of the present application describes the association relationship between associated objects, indicating that three possible relationships exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0161] References throughout this specification to "one embodiment" or "an embodiment" mean that a particular feature, structure, or characteristic associated with the embodiment is included in at least one embodiment of the present application. Therefore, appearances of "in one embodiment" or "in an embodiment" throughout this specification do not necessarily refer to the same embodiment. Furthermore, these particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0162] The present application is described in detail below.

[0163] like Figure 2 FIG. 1 is a flowchart of a data processing method applied to a terminal device according to an embodiment of the present application, and the method includes the following steps:

[0164] Step 101: Receive a fixed frame period FFP transmission pattern sent by a base station; wherein the FFP transmission pattern includes at least one FFP, and the FFP transmission pattern is used to indicate the FFP of the channel occupancy time COT that allows the terminal device UE to be initialized and / or the FFP of the COT that does not allow the UE to be initialized.

[0165] In this embodiment, it should be noted that the difference between this embodiment and the prior art is that the base station no longer needs to indicate through DCI whether the FFP of the next UE can initialize the next COT as in the prior art. Instead, the base station sends an FFP transmission pattern to the UE. The FFP transmission pattern contains at least one FFP. The FFP transmission pattern is used to indicate the FFP of the channel occupancy time COT that allows the terminal device UE to initialize and / or the FFP of the COT that does not allow the UE to initialize. For example, it is assumed that the FFP transmission pattern contains 6 FFPs, and specifies that the 1st, 3rd, and 6th FFPs allow the channel occupancy time COT that allows the terminal device UE to initialize, and the 2nd, 4th, and 5th FFPs do not allow the terminal device UE to initialize. It can be seen that this embodiment sends a fixed frame period FFP transmission pattern to the UE, so that, on the one hand, multiple FFPs of COTs that are allowed to be initialized by the UE can be indicated at one time through the FFP transmission pattern, thereby solving the problem in the prior art that the UE needs to frequently demodulate DCI to obtain whether a COT can be initialized, which affects the UE power consumption. On the other hand, since the FFP transmission pattern can be used to indicate the FFP of the channel occupancy time COT that is allowed to be initialized by the terminal device UE and / or the FFP of the COT that is not allowed to be initialized by the UE, the conflict problem between the COT initialized by the gNB and the COT initialized by the UE can also be solved, thereby improving the resource utilization and throughput of the entire system.

[0166] In this embodiment, it can be understood that there are generally multiple FFPs in the FFP transmission pattern. These multiple FFPs can be all FFPs that allow the execution of the channel occupancy time COT for terminal device UE initialization, or all FFPs that do not allow the execution of the channel occupancy time COT for terminal device UE initialization. They can also be some FFPs that allow the execution of the channel occupancy time COT for terminal device UE initialization, and some FFPs that do not allow the execution of the channel occupancy time COT for terminal device UE initialization. This embodiment does not limit this.

[0167] In addition, in this embodiment, it can be understood that the FFP transmission pattern may also include only one FFP, and specify that the FFP is an FFP that allows the execution of the channel occupancy time COT initialized by the terminal device UE or an FFP that does not allow the execution of the UE-initialized COT (also called UE-initiated COT).

[0168] In this embodiment, it should be noted that the FFP transmission pattern may also be referred to as an FFP transmission pattern. When these two words appear subsequently, their meanings are the same.

[0169] In this embodiment, it should be noted that the gNB can indicate an FFP transmission pattern through higher-layer signaling / Media Access Control Element (MAC CE) / Group Common Downlink Control Information (GC-DCI). Based on this transmission pattern, the UE can determine which FFPs can and cannot perform UE-initiated COT. In this embodiment, it should be noted that the FFP transmission pattern for the UE-initiated COT can be specified using a bitmap. For example, for an 8-bit FFP transmission pattern, a bitmap of "11000110" (1 indicates UE-initiated COT, 0 indicates UE-initiated COT) can be set to specify that the 1st, 2nd, 6th, and 7th FFPs are allowed to perform UE-initiated COT, while the 3rd, 4th, 5th, and 8th FFPs are not allowed to perform UE-initiated COT.

[0170] It should be noted that this transmission pattern can be used periodically and the gNB can modify this transmission pattern through higher-layer signaling / MAC CE / GC-DCI. The bitmap length can be variable (configured through higher-layer parameters (payload size)) or a fixed bit size can be agreed upon in advance, such as 6 bits, 8 bits, 12 bits, etc.

[0171] In this embodiment, it should be noted that N types of FFP transmission patterns may be predefined, and a certain FFP transmission pattern may be designated as a valid FFP transmission pattern for the UE through certain means.

[0172] In this embodiment, it should be noted that for those COTs that the UE is not allowed to initialize, the UE can share the gNB-initiated COT to perform UL service transmission.

[0173] In addition, in this embodiment, if the base station does not configure the FFP transmission pattern, the UE may adopt a default pre-specified FFP transmission pattern.

[0174] In addition, it should be noted that the FFP transmission pattern of the UE and the FFP transmission pattern of the base station can be the same.

[0175] In addition, it should be noted that if the base station does not configure the FFP transmission pattern, the UE can also be determined according to the following rules: for example, for all FFPs in the UE, the UE can perform UE-initiated COT or for all FFPs in the UE, the UE cannot perform UE-initiated COT.

[0176] The data processing method provided in the embodiments of the present application, by receiving a fixed frame period FFP transmission pattern sent by a base station, can, on the one hand, indicate multiple FFPs that allow execution of UE-initialized COTs at one time through the FFP transmission pattern, thereby resolving the problem in the prior art that the UE needs to frequently demodulate DCI to determine whether a COT can be initialized, which affects UE power consumption. On the other hand, because the FFP transmission pattern can indicate the FFP of the channel occupancy time COT that allows execution of UE-initialized COT and / or the FFP of the COT that does not allow execution of UE-initialized COT, the conflict problem between the gNB-initialized COT and the UE-initialized COT can also be resolved, thereby improving the resource utilization and throughput of the entire system.

[0177] Based on the content of the above embodiment, in this embodiment, the fixed frame period FFP transmission pattern sent by the receiving base station includes:

[0178] The fixed frame period FFP transmission pattern is received by the base station through one or more of high-layer signaling, medium access control layer control element MAC CE, and group common downlink control information GC-DCI.

[0179] In this embodiment, it can be understood that there are many ways to send the FFP transmission pattern, including but not limited to sending through high-layer signaling, medium access control layer control unit MAC CE and group common downlink control information GC-DCI. It can be seen that in this embodiment, the UE can receive the FFP transmission pattern sent by the base station through various transmission paths. In actual use, different transmission paths or multiple transmission paths can be selected as needed. Use in combination.

[0180] Based on the content of the above embodiment, in this embodiment, the fixed frame period FFP transmission pattern sent by the receiving base station includes:

[0181] receiving a first FFP transmission pattern sent by a base station; wherein all FFPs in the first FFP transmission pattern have specified whether to allow execution of a UE-initialized COT;

[0182] or,

[0183] receiving a second FFP transmission pattern sent by a base station; wherein the second FFP transmission pattern includes an FFP that does not specify whether to allow execution of a channel occupation time COT for UE initialization;

[0184] or,

[0185] Indication information sent by a base station is received, where the indication information is used to indicate an FFP transmission pattern in a preset FFP transmission pattern group as a valid FFP transmission pattern for the UE.

[0186] In this embodiment, when the base station sends the FFP transmission pattern to the UE, there may be multiple implementation methods. For example, one implementation method is that the base station sends a first FFP transmission pattern to the UE, and all FFPs in the first FFP transmission pattern have specified whether to allow the execution of the UE-initialized COT, that is, the base station sends a determined FFP transmission pattern to the UE. In addition, another implementation method is that the base station sends a second FFP transmission pattern to the UE, and the second FFP transmission pattern contains some or all FFPs that do not specify whether to allow the execution of the UE-initialized channel occupancy time COT. These FFPs that do not specify whether to allow the execution of the UE-initialized channel occupancy time COT can be called Flexible FFPs. For these Flexible FFPs, the base station can further indicate, through DCI, whether the UE can use these Flexible FFPs to initialize the COT.

[0187] For example, the base station can indicate through a mixture of high-layer signaling / MAC CE / DCI. For example, the base station can configure an initial FFP transmission pattern, which includes one or more FlexibleFFPs. The base station then sends the initial FFP transmission pattern to the UE through high-layer signaling. Subsequently, the base station can further indicate through DCI whether the UE can use one or more Flexible FFPs to initialize COT.

[0188] Based on the content of the above embodiment, in this embodiment, the FFPs that allow the UE-initialized COT to be executed and the FFPs that do not allow the UE-initialized COT to be executed in the FFP transmission pattern are distinguished by using bitmap coding.

[0189] In this embodiment, as described above, the FFP transmission pattern includes FFPs for which UE-initialized COT is allowed and FFPs for which UE-initialized COT is not allowed. Bitmap coding is used to distinguish the FFPs for which UE-initialized COT is allowed and the FFPs for which UE-initialized COT is not allowed.

[0190] For example, the length of the FFP transmission pattern can be set as needed. This length is the length of the bitmap encoding, and then 0 and 1 are used to specify whether the UE-initiated COT is allowed. Specifically, 1 indicates that the UE-initiated COT can be performed, and 0 indicates that the UE-initiated COT cannot be performed, thereby achieving the specification of whether the UE-initiated COT is allowed. For example, assuming that an 8-bit FFP transmission pattern needs to be set, and it is necessary to specify that the 1st, 2nd, 6th, and 7th FFPs are allowed to perform the channel occupancy time COT initialized by the terminal device UE, and the 3rd, 4th, 5th, and 8th FFPs are not allowed to perform the channel occupancy time COT initialized by the terminal device UE, the FFP transmission pattern can be expressed by setting the bitmap method of "11000110".

[0191] It should be noted that this transmission pattern can be used periodically and the gNB can modify this transmission pattern through higher-layer signaling / MAC CE / GC-DCI. The bitmap length can be variable (configured through higher-layer parameters (payload size)) or a fixed bit size can be agreed upon in advance, such as 6 bits, 8 bits, 12 bits, etc.

[0192] Based on the content of the above embodiment, in this embodiment, the data processing method further includes:

[0193] The updated FFP transmission pattern is received by the base station through one or more of higher layer signaling, medium access control layer control element MAC CE, and group common downlink control information GC-DCI.

[0194] In this embodiment, it should be noted that the FFP transmission pattern sent by the base station to the UE is not permanent, but can be updated according to actual needs. For example, assuming that the FFP transmission pattern sent by the base station to the UE for the first time is "11000110", and subsequently, based on actual situation analysis, it is determined that the FFP transmission pattern to be sent to the UE is "100101", then the new FFP transmission pattern "100101" can be resent to the UE. It is understood that when sending the updated FFP transmission pattern, it can also be sent through one or more of higher layer signaling, medium access control layer control element MAC CE, and group common downlink control information GC-DCI.

[0195] Based on the content of the above embodiment, in this embodiment, the length of the FFP transmission pattern is variable; the length of the FFP transmission pattern refers to the number of FFPs included in the FFP transmission pattern.

[0196] In this embodiment, it should be noted that the length of the FFP transmission pattern is variable. The length of the FFP transmission pattern refers to the number of FFPs included in the FFP transmission pattern. For example, the length of the FFP transmission pattern can be adjusted by presetting or by configuring high-level parameters.

[0197] Based on the content of the above embodiment, in this embodiment, the length of the FFP transmission pattern is preset or configured through high-level parameters.

[0198] In this embodiment, the length of the FFP transmission pattern can be adjusted by presetting or configuring higher-level parameters to meet actual needs. For example, multiple fixed bit sizes can be pre-set, such as 6 bits, 8 bits, or 12 bits. An FFP transmission pattern of the appropriate length can then be specified or selected during actual use. Furthermore, the FFP transmission pattern length can be configured using higher-level parameters such as payload size.

[0199] Based on the content of the above embodiment, in this embodiment, the FFP transmission pattern is based on a COT bearer initialized by a base station; or, based on a COT bearer initialized by a base station sharing UE.

[0200] In this embodiment, the FFP transmission pattern may be based on a COT bearer initialized by a base station, or may be based on a COT bearer initialized by a base station sharing UE.

[0201] It is understood that when there is a COT initialized by the base station, the FFP transmission pattern can be based on the COT bearer initialized by the base station. When there is no COT initialized by the base station, the FFP transmission pattern can be based on the COT bearer initialized by the base station sharing UE.

[0202] Based on the content of the above embodiment, in this embodiment, the data processing method further includes:

[0203] Receiving a starting point for the FFP transmission pattern configuration from the base station;

[0204] When the FFP transmission pattern is based on a COT bearer initialized by a base station, the effective starting point of the FFP transmission pattern is the first UE FFP after the boundary of the base station FFP where the signaling is located is used as a reference point; wherein the signaling is the signaling by which the base station sends the FFP transmission pattern to the UE;

[0205] When the FFP transmission pattern is based on a COT bearer initialized by a base station sharing a UE, the effective starting point of the FFP transmission pattern is the first UE FFP after the boundary of the UE FFP where the FFP transmission pattern is located is used as a reference point.

[0206] In this embodiment, the base station further configures the effective starting point of the FFP transmission pattern for the UE, so that after receiving the FFP transmission pattern, the UE can know from which FFP of the UE the FFP transmission pattern starts to take effect.

[0207] In this embodiment, for different bearer modes corresponding to the FFP transmission pattern, the method for determining the effective starting point of the FFP transmission pattern is different. Specifically, when the FFP transmission pattern is based on the COT bearer initialized by the base station, the effective starting point of the FFP transmission pattern is the first UE FFP after the boundary of the base station FFP where the signaling is located is the reference point; wherein the signaling is the signaling of the FFP transmission pattern sent by the base station to the UE; when the FFP transmission pattern is based on the COT bearer initialized by the base station shared UE, the effective starting point of the FFP transmission pattern is the first UE FFP after the boundary of the UE FFP where the FFP transmission pattern is located is the reference point.

[0208] Based on the content of the above embodiment, in this embodiment, the fixed frame period FFP transmission pattern sent by the receiving base station includes:

[0209] The receiving base station uses group common downlink control information GC-DCI to send an FFP transmission pattern to a group of UEs; wherein the FFP transmission pattern corresponding to each UE is distinguished by a radio network temporary identifier RNTI, and the FFP transmission pattern of each UE is the same or different.

[0210] In this embodiment, if an FFP transmission pattern needs to be sent to multiple UEs, the base station can use group common downlink control information GC-DCI to send the FFP transmission pattern to a group of UEs. When sending the FFP transmission pattern, it should be noted that the FFP transmission pattern corresponding to each UE is distinguished by using a radio network temporary identifier (RNTI). In addition, it is understood that the FFP transmission pattern of each UE can be the same or different.

[0211] In this embodiment, the RNTI may be UIC-RNTI (UE-Initiated COT-RNTI). In addition, when the FFP transmission pattern is sent to a group of UEs using group common downlink control information GC-DCI, it may be transmitted periodically, and the period may be consistent with the PDCCH monitoring period or a high-level configuration (e.g., monitoringSlotPeriodicityAndOffset).

[0212] Based on the content of the above embodiment, in this embodiment, the data processing method further includes:

[0213] Receive the starting point offset and period of the FFP configured by the base station for the UE;

[0214] The reference time point of the starting point offset is the start time of the FFP where the COT initialized by the base station is located, or the end time of the FFP where the COT initialized by the base station is located, or the start time of the FFP where the physical uplink control channel PUCCH carrying the confirmation ACK is located in the case of a hybrid automatic repeat request confirmation HARQ-ACK, or the end time of the FFP where the PUCCH carrying the ACK is located.

[0215] In this embodiment, the base station also configures the starting point offset and period of the FFP for the UE. Configuring a different FFP period for each UE is mainly based on the different services, data volumes, allocated uplink resources and periods of each UE. Configuring different offsets helps reduce interference between UE transmissions, so configuring different starting point offsets and periods for each UE will be more flexible. Specifically, the reference time point of the starting point offset can be the start time of the FFP where the COT initialized by the base station is located, or the end time of the FFP where the COT initialized by the base station is located, or the start time of the FFP where the physical uplink control channel PUCCH that carries the ACK in the case of a hybrid automatic repeat request confirmation HARQ-ACK is located, or the end time of the FFP where the PUCCH that carries the ACK in the case of a hybrid automatic repeat request confirmation HARQ-ACK is located.

[0216] In this embodiment, it should be noted that when the base station does not configure the starting point offset and period of the FFP for the UE, the starting point and period may be assumed to be the same as the FFP of the base station.

[0217] Based on the content of the above embodiment, in this embodiment, the starting point offset and period are configured by the base station to the FFP of the UE through one or more of high-layer signaling, medium access control layer control element MAC CE and group common downlink control information GC-DCI.

[0218] In this embodiment, the starting point offset and period configured by the base station for the UE may also be sent to the UE using one or more of higher layer signaling, medium access control layer control element MAC CE, and group common downlink control information GC-DCI.

[0219] Based on the content of the above embodiment, in this embodiment, the data processing method further includes:

[0220] For an FFP in the FFP transmission pattern that is not allowed to perform the UE-initiated COT, the UE performs uplink service transmission by sharing the COT initialized by the base station.

[0221] In this embodiment, it is described how to perform uplink service transmission for an FFP in which UE-initialized COT is not allowed to be performed in the FFP transmission pattern. Specifically, for an FFP in which UE-initialized COT is not allowed to be performed in the FFP transmission pattern, the UE can perform uplink service transmission by sharing the COT initialized by the base station.

[0222] Based on the content of the above embodiment, in this embodiment, the data processing method further includes:

[0223] If the FFP transmission pattern sent by the base station is not received, any of the following processes is performed:

[0224] Determine the FFP that allows the UE to initiate the COT using a preset FFP transmission pattern;

[0225] Determine the FFP that allows the UE to initiate the COT using the same FFP transmission pattern as the base station;

[0226] Determine all UE FFPs as FFPs that allow the execution of UE-initialized COT;

[0227] All UE FFPs are determined as FFPs that are not allowed to perform UE-initialized COT.

[0228] In this embodiment, if the FFP transmission pattern sent by the base station is not received, any of the following processing methods may be used to determine whether the UE's FFP allows execution of the UE-initialized COT. For example, if the FFP transmission pattern sent by the base station is not received, a preset or pre-stored FFP transmission pattern may be used to determine the FFP that allows execution of the UE-initialized COT according to a pre-defined protocol. For another example, if the FFP transmission pattern sent by the base station is not received, a pre-agreed FFP transmission pattern identical to that of the base station may be used to determine the FFP that allows execution of the UE-initialized COT. For another example, if the FFP transmission pattern sent by the base station is not received, all UE FFPs may be determined as FFPs that allow execution of the UE-initialized COT according to a pre-defined protocol. For another example, if the FFP transmission pattern sent by the base station is not received, all UE FFPs may be determined as FFPs that allow execution of the UE-initialized COT according to a pre-defined protocol. For another example, if the FFP transmission pattern sent by the base station is not received, all UE FFPs may be determined as FFPs that do not allow execution of the UE-initialized COT according to a pre-defined protocol, and so on.

[0229] like Figure 3 FIG. 1 is a flowchart of a data processing method applied to a base station side according to an embodiment of the present application, and the method includes the following steps:

[0230] Step 201: Send a fixed frame period FFP transmission pattern to a terminal device UE; wherein the FFP transmission pattern includes at least one FFP, and the FFP transmission pattern is used to indicate the FFP of the channel occupancy time COT that allows UE initialization and / or the FFP of the COT that does not allow UE initialization.

[0231] In this embodiment, it should be noted that the difference between this embodiment and the prior art is that the base station no longer needs to indicate through DCI whether the FFP of the next UE can initialize the next COT as in the prior art. Instead, the base station sends an FFP transmission pattern to the UE. The FFP transmission pattern contains at least one FFP. The FFP transmission pattern is used to indicate the FFP of the channel occupancy time COT that allows the terminal device UE to initialize and / or the FFP of the COT that does not allow the UE to initialize. For example, it is assumed that the FFP transmission pattern contains 6 FFPs, and specifies that the 1st, 3rd, and 6th FFPs allow the channel occupancy time COT that allows the terminal device UE to initialize, and the 2nd, 4th, and 5th FFPs do not allow the terminal device UE to initialize. It can be seen that this embodiment sends a fixed frame period FFP transmission pattern to the UE, so that, on the one hand, multiple FFPs of COTs that are allowed to be initialized by the UE can be indicated at one time through the FFP transmission pattern, thereby solving the problem in the prior art that the UE needs to frequently demodulate DCI to obtain whether a COT can be initialized, which affects the UE power consumption. On the other hand, since the FFP transmission pattern can be used to indicate the FFP of the channel occupancy time COT that is allowed to be initialized by the terminal device UE and / or the FFP of the COT that is not allowed to be initialized by the UE, the conflict problem between the COT initialized by the gNB and the COT initialized by the UE can also be solved, thereby improving the resource utilization and throughput of the entire system.

[0232] In this embodiment, it can be understood that there are generally multiple FFPs in the FFP transmission pattern. These multiple FFPs can be all FFPs that allow the execution of the channel occupancy time COT for terminal device UE initialization, or all FFPs that do not allow the execution of the channel occupancy time COT for terminal device UE initialization. They can also be some FFPs that allow the execution of the channel occupancy time COT for terminal device UE initialization, and some FFPs that do not allow the execution of the channel occupancy time COT for terminal device UE initialization. This embodiment does not limit this.

[0233] In addition, in this embodiment, it can be understood that the FFP transmission pattern may also include only one FFP, and specify that the FFP is an FFP that allows the execution of the channel occupancy time COT initialized by the terminal device UE or an FFP that does not allow the execution of the UE-initialized COT (also called UE-initiated COT).

[0234] In this embodiment, it should be noted that the FFP transmission pattern may also be referred to as an FFP transmission pattern. When these two words appear subsequently, their meanings are the same.

[0235] In this embodiment, it should be noted that the gNB can indicate an FFP transmission pattern through higher-layer signaling / Media Access Control Element (MAC CE) / Group Common Downlink Control Information (GC-DCI). Based on this transmission pattern, the UE can determine which FFPs can and cannot perform UE-initiated COT. In this embodiment, it should be noted that the FFP transmission pattern for the UE-initiated COT can be specified using a bitmap. For example, for an 8-bit FFP transmission pattern, a bitmap of "11000110" (1 indicates UE-initiated COT, 0 indicates UE-initiated COT) can be set to specify that the 1st, 2nd, 6th, and 7th FFPs are allowed to perform UE-initiated COT, while the 3rd, 4th, 5th, and 8th FFPs are not allowed to perform UE-initiated COT.

[0236] It should be noted that this transmission pattern can be used periodically and the gNB can modify this transmission pattern through higher-layer signaling / MAC CE / GC-DCI. The bitmap length can be variable (configured through higher-layer parameters (payload size)) or a fixed bit size can be agreed upon in advance, such as 6 bits, 8 bits, 12 bits, etc.

[0237] In this embodiment, it should be noted that N types of FFP transmission patterns may be predefined, and a certain FFP transmission pattern may be designated as a valid FFP transmission pattern for the UE through certain means.

[0238] In this embodiment, it should be noted that for those COTs that the UE is not allowed to initialize, the UE can share the gNB-initiated COT to perform UL service transmission.

[0239] In addition, in this embodiment, if the base station does not configure the FFP transmission pattern, the UE may adopt a default pre-specified FFP transmission pattern.

[0240] In addition, it should be noted that the FFP transmission pattern of the UE and the FFP transmission pattern of the base station can be the same.

[0241] In addition, it should be noted that if the base station does not configure the FFP transmission pattern, the UE can also be determined according to the following rules: for example, for all FFPs in the UE, the UE can perform UE-initiated COT or for all FFPs in the UE, the UE cannot perform UE-initiated COT.

[0242] The data processing method provided in the embodiment of the present application sends a fixed frame period FFP transmission pattern to the UE. On the one hand, the FFP transmission pattern can be used to indicate multiple FFPs that allow the execution of UE-initialized COTs at one time, thereby solving the problem in the prior art that the UE needs to frequently demodulate DCI to determine whether a COT can be initialized, which affects the UE power consumption. On the other hand, because the FFP transmission pattern can be used to indicate the FFP of the channel occupancy time COT that allows the execution of the terminal device initialized COT and / or the FFP of the COT that does not allow the execution of the UE-initialized COT, the conflict problem between the gNB-initialized COT and the UE-initialized COT can also be solved, thereby improving the resource utilization and throughput of the entire system.

[0243] Based on the content of the above embodiment, in this embodiment, sending a fixed frame period FFP transmission pattern to a terminal device UE includes:

[0244] The fixed frame period FFP transmission pattern is sent to the terminal device UE through one or more of high-layer signaling, medium access control layer control element MAC CE and group common downlink control information GC-DCI.

[0245] In this embodiment, it can be understood that there are many ways to send the FFP transmission pattern, including but not limited to sending through high-layer signaling, medium access control layer control unit MAC CE and group common downlink control information GC-DCI. It can be seen that in this embodiment, the UE can receive the FFP transmission pattern sent by the base station through various transmission paths. In actual use, different transmission paths or multiple transmission paths can be selected as needed. Use in combination.

[0246] Based on the content of the above embodiment, in this embodiment, sending a fixed frame period FFP transmission pattern to a terminal device UE includes:

[0247] Sending a first FFP transmission pattern to the UE; all FFPs in the first FFP transmission pattern have specified whether to allow UE-initialized COT;

[0248] or,

[0249] Sending a second FFP transmission pattern to the UE; wherein the second FFP transmission pattern includes an FFP that does not specify whether to allow execution of a channel occupation time COT for UE initialization;

[0250] or,

[0251] An FFP transmission pattern in a preset FFP transmission pattern group is designated as a valid FFP transmission pattern for the UE.

[0252] In this embodiment, when the base station sends the FFP transmission pattern to the UE, there may be multiple implementation methods. For example, one implementation method is that the base station sends a first FFP transmission pattern to the UE, and all FFPs in the first FFP transmission pattern have specified whether to allow the execution of the UE-initialized COT, that is, the base station sends a determined FFP transmission pattern to the UE. In addition, another implementation method is that the base station sends a second FFP transmission pattern to the UE, and the second FFP transmission pattern contains some or all FFPs that do not specify whether to allow the execution of the UE-initialized channel occupancy time COT. These FFPs that do not specify whether to allow the execution of the UE-initialized channel occupancy time COT can be called Flexible FFPs. For these Flexible FFPs, the base station can further indicate, through DCI, whether the UE can use these Flexible FFPs to initialize the COT.

[0253] For example, the base station can indicate through a mixture of high-layer signaling / MAC CE / DCI. For example, the base station can configure an initial FFP transmission pattern, which includes one or more FlexibleFFPs. The base station then sends the initial FFP transmission pattern to the UE through high-layer signaling. Subsequently, the base station can further indicate through DCI whether the UE can use one or more Flexible FFPs to initialize COT.

[0254] Based on the content of the above embodiment, in this embodiment, the FFPs that allow the UE-initialized COT to be executed and the FFPs that do not allow the UE-initialized COT to be executed in the FFP transmission pattern are distinguished by using bitmap coding.

[0255] In this embodiment, as described above, the FFP transmission pattern includes FFPs for which UE-initialized COT is allowed and FFPs for which UE-initialized COT is not allowed. Bitmap coding is used to distinguish the FFPs for which UE-initialized COT is allowed and the FFPs for which UE-initialized COT is not allowed.

[0256] For example, the length of the FFP transmission pattern can be set as needed. This length is the length of the bitmap encoding, and then 0 and 1 are used to specify whether the UE-initiated COT is allowed. Specifically, 1 indicates that the UE-initiated COT can be performed, and 0 indicates that the UE-initiated COT cannot be performed, thereby achieving the specification of whether the UE-initiated COT is allowed. For example, assuming that an 8-bit FFP transmission pattern needs to be set, and it is necessary to specify that the 1st, 2nd, 6th, and 7th FFPs are allowed to perform the channel occupancy time COT initialized by the terminal device UE, and the 3rd, 4th, 5th, and 8th FFPs are not allowed to perform the channel occupancy time COT initialized by the terminal device UE, the FFP transmission pattern can be expressed by setting the bitmap method of "11000110".

[0257] It should be noted that this transmission pattern can be used periodically and the gNB can modify this transmission pattern through higher-layer signaling / MAC CE / GC-DCI. The bitmap length can be variable (configured through higher-layer parameters (payload size)) or a fixed bit size can be agreed upon in advance, such as 6 bits, 8 bits, 12 bits, etc.

[0258] Based on the content of the above embodiment, in this embodiment, the data processing method further includes:

[0259] The updated FFP transmission pattern is sent to the terminal device UE through one or more of high-layer signaling, medium access control layer control unit MAC CE and group common downlink control information GC-DCI.

[0260] In this embodiment, it should be noted that the FFP transmission pattern sent by the base station to the UE is not permanent, but can be updated according to actual needs. For example, assuming that the FFP transmission pattern sent by the base station to the UE for the first time is "11000110", and subsequently, based on actual situation analysis, it is determined that the FFP transmission pattern to be sent to the UE is "100101", then the new FFP transmission pattern "100101" can be resent to the UE. It is understood that when sending the updated FFP transmission pattern, it can also be sent through one or more of higher layer signaling, medium access control layer control element MAC CE, and group common downlink control information GC-DCI.

[0261] Based on the content of the above embodiment, in this embodiment, the length of the FFP transmission pattern is variable; the length of the FFP transmission pattern refers to the number of FFPs included in the FFP transmission pattern.

[0262] In this embodiment, it should be noted that the length of the FFP transmission pattern is variable. The length of the FFP transmission pattern refers to the number of FFPs included in the FFP transmission pattern. For example, the length of the FFP transmission pattern can be adjusted by presetting or by configuring high-level parameters.

[0263] Based on the content of the above embodiment, in this embodiment, the length of the FFP transmission pattern is preset or configured through high-level parameters.

[0264] In this embodiment, the length of the FFP transmission pattern can be adjusted by presetting or configuring high-level parameters to meet actual needs.

[0265] For example, multiple fixed bit sizes can be pre-set, such as 6 bits, 8 bits, or 12 bits. An FFP transmission pattern of the appropriate length can then be specified or selected during actual use. Furthermore, the FFP transmission pattern length can be configured using higher-level parameters such as payload size.

[0266] Based on the content of the above embodiment, in this embodiment, the FFP transmission pattern is based on a COT bearer initialized by a base station; or, based on a COT bearer initialized by a base station sharing UE.

[0267] In this embodiment, the FFP transmission pattern may be based on a COT bearer initialized by a base station, or may be based on a COT bearer initialized by a base station sharing UE.

[0268] It is understood that when there is a COT initialized by the base station, the FFP transmission pattern can be based on the COT bearer initialized by the base station. When there is no COT initialized by the base station, the FFP transmission pattern can be based on the COT bearer initialized by the base station sharing UE.

[0269] Based on the content of the above embodiment, in this embodiment, the data processing method further includes:

[0270] Configuring a valid starting point for the FFP transmission pattern;

[0271] When the FFP transmission pattern is based on a COT bearer initialized by a base station, the effective starting point of the FFP transmission pattern is the first UE FFP after the boundary of the base station FFP where the signaling is located is used as a reference point; wherein the signaling is the signaling by which the base station sends the FFP transmission pattern to the UE;

[0272] When the FFP transmission pattern is based on a COT bearer initialized by a base station sharing a UE, the effective starting point of the FFP transmission pattern is the first UE FFP after the boundary of the UE FFP where the FFP transmission pattern is located is used as a reference point.

[0273] In this embodiment, the base station further configures the effective starting point of the FFP transmission pattern for the UE, so that after receiving the FFP transmission pattern, the UE can know from which FFP of the UE the FFP transmission pattern starts to take effect.

[0274] In this embodiment, for different bearer modes corresponding to the FFP transmission pattern, the method for determining the effective starting point of the FFP transmission pattern is different. Specifically, when the FFP transmission pattern is based on the COT bearer initialized by the base station, the effective starting point of the FFP transmission pattern is the first UE FFP after the boundary of the base station FFP where the signaling is located is the reference point; wherein the signaling is the signaling of the FFP transmission pattern sent by the base station to the UE; when the FFP transmission pattern is based on the COT bearer initialized by the base station shared UE, the effective starting point of the FFP transmission pattern is the first UE FFP after the boundary of the UE FFP where the FFP transmission pattern is located is the reference point.

[0275] Based on the content of the above embodiment, in this embodiment, sending a fixed frame period FFP transmission pattern to a terminal device UE includes:

[0276] The FFP transmission pattern is sent to a group of UEs using group common downlink control information GC-DCI; wherein the FFP transmission pattern corresponding to each UE is distinguished by a radio network temporary identifier RNTI, and the FFP transmission pattern of each UE is the same or different.

[0277] In this embodiment, if an FFP transmission pattern needs to be sent to multiple UEs, the base station can use group common downlink control information GC-DCI to send the FFP transmission pattern to a group of UEs. When sending the FFP transmission pattern, it should be noted that the FFP transmission pattern corresponding to each UE is distinguished by using a radio network temporary identifier (RNTI). In addition, it is understood that the FFP transmission pattern of each UE can be the same or different.

[0278] In this embodiment, the RNTI may be a UIC-RNTI or a UE-Initiated COT-RNTI. Furthermore, when the FFP transmission pattern is sent to a group of UEs using group common downlink control information (GC-DCI), the transmission may be periodic, and the period may be consistent with the PDCCH monitoring period or a higher-level configuration (e.g., monitoringSlotPeriodicityAndOffset).

[0279] Based on the content of the above embodiment, in this embodiment, the data processing method further includes:

[0280] Configure the starting point offset and period for the UE's FFP;

[0281] The reference time point of the starting point offset is the start time of the FFP where the COT initialized by the base station is located, or the end time of the FFP where the COT initialized by the base station is located, or the start time of the FFP where the physical uplink control channel PUCCH carrying the confirmation ACK is located in the case of a hybrid automatic repeat request confirmation HARQ-ACK, or the end time of the FFP where the PUCCH carrying the ACK is located.

[0282] In this embodiment, the base station also configures the starting point offset and period of the FFP for the UE. Configuring a different FFP period for each UE is mainly based on the different services, data volumes, allocated uplink resources and periods of each UE. Configuring different offsets helps reduce interference between UE transmissions, so configuring different starting point offsets and periods for each UE will be more flexible. Specifically, the reference time point of the starting point offset can be the start time of the FFP where the COT initialized by the base station is located, or the end time of the FFP where the COT initialized by the base station is located, or the start time of the FFP where the physical uplink control channel PUCCH that carries the ACK in the case of a hybrid automatic repeat request confirmation HARQ-ACK is located, or the end time of the FFP where the PUCCH that carries the ACK in the case of a hybrid automatic repeat request confirmation HARQ-ACK is located.

[0283] In this embodiment, it should be noted that when the base station does not configure the starting point offset and period of the FFP for the UE, the starting point and period may be assumed to be the same as the FFP of the base station.

[0284] Based on the content of the above embodiment, in this embodiment, the starting point offset and period are indicated by one or more of higher layer signaling, medium access control layer control element MAC CE and group common downlink control information GC-DCI.

[0285] In this embodiment, the starting point offset and period configured by the base station for the UE may also be sent to the UE using one or more of higher layer signaling, medium access control layer control element MAC CE, and group common downlink control information GC-DCI.

[0286] The present application will be described in detail below through specific embodiments.

[0287] First embodiment:

[0288] In this embodiment, the gNB indicates an FFP transmission pattern via higher-layer signaling / MAC CE. Based on this transmission pattern, the UE determines which FFPs can and cannot perform UE-initiated COT (Channel Occupation Time). For those FFPs for which the UE is not permitted to initiate COT, the UE can use gNB-initiated COT to transmit UL services. If the base station does not configure a transmission pattern, the default is that the UE and base station patterns can be the same, the UE can perform UE-initiated COT for all FFPs, or the UE cannot perform UE-initiated COT for all FFPs.

[0289] The FFP transmission pattern where UE-initiated COT is located can be indicated by a bitmap to indicate whether a set of FFPs of the UE can execute UE-initiated COT. 1 indicates that UE-initiated COT can be executed, and 0 indicates that UE-initiated COT cannot be executed. This transmission pattern can be used periodically or pre-defined N types of FFP transmission patterns, and one of the patterns is indicated by A=ceil(log2N) bits. At the same time, the gNB can modify this transmission pattern through higher-layer signaling / MAC CE. The length of the transmission pattern bitmap is variable (configurable through higher-layer parameters (payload size)) or a fixed bit size is agreed in advance. The bitmap indicating the transmission pattern based on MAC CE is as follows: Figure 4 shown. Figure 4 It is just the specific bitmap length of the diagram, the network can be configured according to the actual situation. Figure 4 In the example, the bitmap length is set to 8 bits to indicate 8 FFPs, and the transmission pattern of FFP is also repeated with 8 FFPs as a period. Figure 5 This is a schematic diagram of the RRC high-level signaling bearer transmission pattern indication information bitmap. Figure 5 In the Payloadsize parameter, there are N bits in total, and its value range is [0, M]. The specific value of the Payloadsize parameter indicates the bit length of the FFP bitmap. The network uses the bit length of Payloadsize to set the UE transmission pattern. If the network does not configure the FFP transmission pattern through high-level signaling / MAC CE, the UE's default transmission pattern can be the same as the base station's pattern, or the UE can perform UE-initiated COT for all FFPs, or the UE cannot perform UE-initiated COT for all FFPs. Figure 6 and Figure 7 As shown in Figure 2, gNB can carry the transmission pattern of UE-initiated COT in two ways. One is to use the transmission pattern of UE-initiated COT carried by gNB-initiated COT (such as Figure 6 As shown), the other is gNB sharing UE-initiated COT to carry UE-initiated COT (as shown Figure 7 shown).

[0290] In addition, it should be noted that if Figure 8 As shown, the gNB can update the UE-initiated COT transmission pattern based on network conditions. Updates can be periodic or dynamic, and can be communicated through higher-layer signaling, MAC CE, or DCI. UE-initiated COT transmission pattern updates can be based on the gNB-initiated COT bearer or by gNB sharing the UE-initiated COT bearer. Alternatively, the gNB can indicate this through a combination of higher-layer signaling, MAC CE, and DCI. For example, the gNB can configure an initial pattern that includes some Flexible FFPs and then indicate the availability of these Flexible FFPs through MAC CE or DCI. In this case, the gNB can send a list of available patterns to the UE and then indicate a pattern through MAC CE or DCI. If the pattern includes a Flexible FFP, the gNB further indicates through DCI whether the UE can use this FFP to initialize a COT.

[0291] In addition, the effective starting point of the FFP transmission pattern is the first UE FFP after the boundary of the base station FFP where the signaling is located is the reference point. Figure 9 and Figure 10 As shown, the effective starting point of the FFP transmission pattern is the boundary of the FFP carrying the FFP transmission pattern, and the FFP for UE-initiated COT that is closest to it in time starts to implement the transmission pattern.

[0292] In addition, for the FFP where the UE-initiated COT is located, the gNB configures a starting point offset and period for each UE's FFP (Fix frame period) through high-layer signaling / MAC CE / DCI. If not configured, the default starting point and period are the same as the COT initialized by the gNB or the UE can initialize a COT. Figure 11 and Figure 12As shown, there are two ways to use the reference point for the UE's FFP starting point: one is to use the start time of the FFP where the gNB-initiated COT is located as the reference time point, and the other is to use the end time of the FFP where the gNB-initiated COT is located as the reference time point. Alternatively, if there is HARQ-ACK feedback, it can take effect after the HARQ-ACK reply (ACK); specifically, it can be based on the start time or end time of the FFP where the PUCCH carrying the ACK is located.

[0293] See also Figure 13 , Figure 14 As shown in Table 1, the gNB can indicate the offset and period of the UE-initiated COT FFP using RRC / MAC CE / DCI. Alternatively, a combination of the three methods can be used. For example, the UE FFP offset and period can be initially configured via RRC and updated via MAC CE / DCI. Alternatively, a set of UE FFP offsets and periods can be broadcast via RRC, and the offset and period of a specific FFP can be indicated via MAC CE / DCI. The FFP period can be configured with reference to the PUSCH period of the UE's CG. If the UE has multiple PUSCH CGs configured, the gNB can select a single period as a reference. If the UE's FFP period is smaller than the gNB's period, the gNB can configure the FFP periods of multiple UEs to be equal to the period of a single gNB FFP. This allows for more flexible and simplified configuration of the UE's FFP offer and period.

[0295] Information in DCI bits Offset indicator of UE FFP(Slot) P Period(Slot) Q

[0296] Second embodiment:

[0297] In this embodiment, the gNB uses group common DCI (GC-DCI) to indicate a group of UEs (as shown in Table 2 below). If GC-DCI is used to indicate a group of UEs, a new (UIC-RNTI, UE-Initiated COT-RNTI) is used. It can be periodic transmission. The period can be consistent with the PDCCH monitoring period or configured by the higher layer. The time domain and frequency domain resources can use the higher layer indication (timeFrequencyRegion). Multiple UEs can be configured with the same transmission pattern or different patterns. These patterns are all indicated by bitmaps, and the bitmap length is indicated by the higher layer. Figure 15As shown, the GC-DCI indicates the transmission patterns of two UEs, and the transmission patterns of these two UEs are different.

[0298] Table 2 Example of gNB using GC-DCI to indicate a group of UEs

[0299] Information in DCI bits UE1 transmission pattern N1 UE2 transmission pattern N2 … … UEj transmission pattern Nj

[0300] In addition, the period can be consistent with the PDCCH monitoring period or configured by a higher layer (monitoringSlotPeriodicityAndOffset). The gNB will also assign the GC-DCI of the transmission pattern of this UE-Initiated COT to a CORESET (Control Resource Set). The UE will use the UIC-RNTI to search for the GC-DCI of the transmission pattern of this UE-Initiated COT on this CORESET. Figure 16 shown.

[0301] It can be understood that the embodiment of the present application can improve resource utilization and the throughput of the entire system by introducing the FFP pattern transmission mechanism of UE-initialized COT controlled by gNB, while reducing the number of UE blind detection DCIs and thus reducing UE power consumption.
