Description

Data processing method, device, terminal equipment, base station and storage medium

Technical Field

The present application relates to the field of communications technologies, and in particular, to a data processing method, an apparatus, a terminal device, a base station, and a storage medium.

Background

Currently 5G NR-U (5)^thTwo Channel Occupation Time (COT) initialization modes are supported in a generation new radio unlicensed frequency band system, one mode is a COT (channel allocation time) initialized by a base station gNB (g Node B), and the other mode is a COT initialized by a terminal equipment UE (user Equipment), if the COT initialized by the gNB and the COT initialized by the UE overlap in time, if the COT initialized by the UE is earlier than the COT initialized by the gNB in timeThe initialized COT may cause the gNB to fail to initialize a COT and thus to schedule other UEs.

In order to solve the problem of mutual conflict between COTs initialized by a gNB and a UE under the coexistence condition of the COT initialized by the UE, the current method indicates whether the UE can initialize the next COT through downlink Control information dci (downlink Control information). However, the problem of indicating whether the fixed Frame period ffp (fix Frame period) of the next UE can initialize the next COT through the DCI is that the UE needs to frequently demodulate the DCI to obtain whether one COT can be initialized, which may affect the power consumption of the UE.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Note that, as shown in FIG. 1, 5G NR-U (5) is currently used^thTwo Channel Occupation Time (COT) initialization modes are supported in a generation new radio unlicensed frequency band system, one mode is a COT initialized by a base station gNB (g Node B), and the other mode is a COT initialized by a terminal equipment UE (user Equipment), if the COT initialized by the gNB and the COT initialized by the UE overlap in time, if the COT initialized by the UE is earlier than the COT initialized by the gNB in time, the gNB cannot initialize one COT, so that other UEs cannot be scheduled. Since the UE-initialized COT can only be used for its own transmissions and the gNB transmissions (broadcast signaling and HARQ-ACK feedback and scheduling retransmission for the UE), other UEs cannot send uplink transmissions within the COT, which also results in a decrease in resource utilization and a decrease in overall system throughput. There is therefore a need to solve the conflict problem between UE-initiated COT and gNB-initiated COT.

In order to solve the problem of mutual conflict between COTs initialized by a gNB and a UE under the coexistence condition of the COT initialized by the UE, the current method indicates whether the UE can initialize the next COT through downlink Control information dci (downlink Control information). However, the problem of indicating whether the fixed Frame period ffp (fix Frame period) of the next UE can initialize the next COT through the DCI is that the UE needs to frequently demodulate the DCI to obtain whether one COT can be initialized, which may affect the power consumption of the UE, and now the specific analysis is as follows:

5G NR-U, 5G New radio in Ullicensed Spectrum is a 5G air interface working in an Unlicensed frequency band. The frequency spectrum can be used without authorization from a competent organization under the condition of meeting the regulatory rule.

Currently, the 5G NR-U defines two types of devices, one type being a Frame Based device (FBE) and the other type being a Load Based device (LBE). For FBE, a period is set, and Channel detection is performed once at a fixed position of each period, for example, CCA (Clear Channel Assessment) detection is performed during each CCA detection time. If the channel state is detected to be idle, the channel can be occupied for transmission; if the channel state is detected to be non-idle, the device cannot occupy the channel in the period until the fixed position of the next period is waited to continue to detect. If the CCA is performed for interference detection in each period, a large processing overhead is incurred for the device, and the success rate of accessing the channel cannot be guaranteed. For FBE, two ways of initializing COT (channel allocation time) are supported at present, including gNB-initialized COT and UE-initialized COT. In order to solve the problem of mutual conflict between COTs initialized by a gNB and a UE under the coexistence condition of the COT initialized by the UE, the current method indicates whether the UE can initialize the next COT through downlink Control information dci (downlink Control information). However, the issue of indicating whether the fixed Frame period ffp (fix Frame period) of the next UE can initialize the next COT through the DCI is that the UE needs to frequently demodulate the DCI to obtain whether one COT can be initialized, which may affect the power consumption of the UE, and if the gNB cannot successfully initialize one COT, it cannot indicate whether the UE can initialize the next COT. This may cause the UE to rely only on the gNB-initialized COT if there is traffic to transmit, and may cause the UE to fail to transmit data if the gNB fails to initialize the COT. In addition, whether the UE can initialize the next COT is indicated by the DCI, and the problem that the gNB cannot initialize one COT if the UE successfully initializes the COT earlier than the gNB initialized COT in time under the condition that the gNB initialized COT and the UE initialized COT overlap in time cannot be solved. In order to solve the problem, an embodiment of the present application provides a data processing method, where a fixed frame period FFP transmission pattern is sent to a UE, so that on one hand, FFPs of multiple COTs allowed to perform UE initialization can be indicated at a time through the FFP transmission pattern, and thus a problem in the prior art that power consumption of the UE is affected because the UE needs to frequently demodulate DCI to obtain whether one COT can be initialized or not can be solved, and on the other hand, because FFPs of a channel occupation time COT allowed to perform UE initialization and/or FFPs of COTs not allowed to perform UE initialization can be indicated through the FFP transmission pattern, a problem of collision between a COT initialized by a gNB and a COT initialized by the UE can also be solved, and thus resource utilization rate of the entire system and throughput of the entire system can be improved. The data processing method, apparatus, terminal device, base station, and storage medium provided by the present application are explained and explained in detail by specific embodiments below.

It should be noted that, in the following description, since the method and the apparatus are based on the same application concept, and the principles of solving the problems of the method and the apparatus are similar, the implementation of the apparatus and the method can be mutually referred, and repeated details are not repeated.

In addition, it should be noted that the technical solutions provided in the embodiments of the present application may be applied to various systems, especially 5G systems. For example, the applicable system may be a global system for mobile communication (GSM) system, a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) General Packet Radio Service (GPRS) system, a long term evolution (long term evolution, LTE) system, an LTE Frequency Division Duplex (FDD) system, an LTE Time Division Duplex (TDD) system, an LTE-a (long term evolution) system, a universal mobile system (universal mobile telecommunications system, UMTS), a Worldwide Interoperability for Mobile Access (WiMAX) system, a New Radio network (NR 5) system, etc. These various systems include terminal devices and network devices.

The terminal device referred to in the embodiments of the present application may refer to a device providing voice and/or data connectivity to a user, a handheld device having a wireless connection function, or another processing device connected to a wireless modem. In different systems, the names of the terminal devices may be different, for example, in a 5G system, the terminal device may be called a User Equipment (UE). A wireless terminal device, which may be a mobile terminal device such as a mobile telephone (or "cellular" telephone) and a computer having a mobile terminal device, for example, a portable, pocket, hand-held, computer-included, or vehicle-mounted mobile device, may communicate with one or more Core Networks (CNs) via a Radio Access Network (RAN). Examples of such devices include Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs). The wireless terminal device may also be referred to as a system, a subscriber unit (subscriber unit), a subscriber station (subscriber station), a mobile station (mobile), a remote station (remote station), an access point (access point), a remote terminal device (remote terminal), an access terminal device (access terminal), a user terminal device (user terminal), a user agent (user agent), and a user device (user device), which are not limited in this embodiment of the present application. Since the terminal device forms a network capable of supporting communication with other network devices (e.g., a core network device, an access network device (i.e., a base station)), the terminal device is also considered as a network device in the present invention.

The base station according to the embodiment of the present application may include a plurality of cells for providing services to the terminal, and may also be a CU (Central Unit) or a DU (Distributed Unit). Which may also be referred to as an access point, or a device in an access network that communicates over the air-interface, through one or more sectors, with wireless terminal devices, or by other names, depending on the particular application. The base station may be configured to exchange received air frames with Internet Protocol (IP) packets as a router between the wireless terminal device and the rest of the access network, which may include an Internet Protocol (IP) communications network. The network device may also coordinate attribute management for the air interface.

Furthermore, it should be understood that the term "and/or" in the embodiments of the present application describes an association relationship of associated objects, and means that there may be three relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

Reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present application. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

The present application is explained in detail below.

As shown in fig. 2, a flowchart of steps of a data processing method applied to a terminal device according to an embodiment of the present application is provided, where the method includes the following steps:

step 101: receiving a Fixed Frame Period (FFP) transmission pattern sent by a base station; the FFP transmission pattern comprises at least one FFP, and the FFP transmission pattern is used for indicating the FFP which allows the execution of the channel occupancy time COT of the UE initialization of the terminal equipment and/or the FFP which does not allow the execution of the COT of the UE initialization.

In this embodiment, it should be noted that, the difference between this embodiment and the prior art is that, instead of indicating whether the FFP of the next UE can initialize the next COT through DCI as in the prior art, the base station sends to the UE an FFP transmission pattern, where the FFP transmission pattern includes at least one FFP, where the FFP transmission pattern is used to indicate an FFP that allows performing the channel occupancy time COT of the UE initialization of the terminal device and/or an FFP that does not allow performing the COT of the UE initialization, for example, it is assumed that the FFP transmission pattern includes 6 FFPs and specifies the channel occupancy time COT that the FFPs 1, 3, and 6 are allowed to perform the UE initialization of the terminal device, and the FFPs 2, 4, and 5 are not allowed to perform the channel occupancy time COT of the UE initialization of the terminal device, and thus, this embodiment sends to the FFP transmission pattern with a fixed frame period, the FFP indicating the plurality of FFPs allowing the UE to perform the UE-initialized COT can be indicated at one time through the FFP transmission pattern, so that the problem that in the prior art, the UE power consumption is affected by whether the UE can initialize one COT or not due to the fact that the UE needs to frequently demodulate DCI to obtain the DCI can be solved, and on the other hand, the problem of collision between the gNB-initialized COT and the UE-initialized COT can be solved due to the fact that the FFP indicating the UE-initialized channel occupation time COT allowed to perform the UE initialization and/or the FFP not allowed to perform the UE-initialized COT can be indicated through the FFP transmission pattern, so that the resource utilization rate of the whole system and the throughput of the whole system can be improved.

In this embodiment, it can be understood that, in the FFP transmission pattern, there are generally a plurality of FFPs, and these FFPs may all be FFPs that allow execution of the channel occupancy time COT for the UE initialization, or all be FFPs that do not allow execution of the channel occupancy time COT for the UE initialization, or may be FFPs that do not allow execution of the channel occupancy time COT for the UE initialization, which is not limited in this embodiment.

In addition, in this embodiment, it may be understood that the FFP transmission pattern may also include only one FFP, and the FFP is designated as an FFP that allows performing a channel occupancy time COT for UE initialization of the terminal device or an FFP that does not allow performing a COT for UE initialization (also referred to as UE-initialized COT).

In this embodiment, it should be noted that the FFP transmission pattern may also be referred to as an FFP transmission pattern, and when these two words appear later, their meanings are consistent.

In this embodiment, it should be noted that, the gNB may indicate an FFP transmission pattern through a Media Access Control Element MAC CE (Media Access Control Element)/group common-Downlink Control Information GC-DCI (group common-Downlink Control Information), and the UE may know which FFPs can execute the UE-initiated COT and which FFPs cannot execute the UE-initiated COT according to the transmission pattern. In this embodiment, it should be noted that, the FFP transmission pattern where the UE-initiated COT is located may be specified in a bitmap manner, for example, for an 8-bit FFP transmission pattern, the 1 st, 2 nd, 6 th, and 7 th FFPs may be specified in a bitmap manner (1 indicates that the UE-initiated COT may be executed, and 0 indicates that the UE-initiated COT may not be executed) of "11000110" to specify the channel occupation time COT that the FFP allows the terminal device UE to be initialized, and the 3 rd, 4 th, 5 th, and 8 th FFPs may not allow the terminal device UE to be initialized.

It should be noted that the transmission pattern may be used periodically, and the gNB may modify the transmission pattern through higher layer signaling/MAC CE/GC-DCI, where the length of the bitmap is variable (configurable through a higher layer parameter (payload size)) or a fixed bit size is predetermined in advance, for example, the size may be 6 bits, 8 bits, 12 bits, and so on.

In this embodiment, it should be noted that N types of FFP transmission patterns may be defined in advance, and a certain FFP transmission pattern may be specified as an FFP transmission pattern valid for the UE by a certain means.

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-initialized COT to perform transmission of the UL traffic.

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

Note that the FFP transmission pattern of the UE may be the same as the FFP transmission pattern of the base station.

In addition, it should be noted that, if the base station does not configure the FFP transmission pattern, the UE may also determine according to the following rule: for example, the UE may perform the UE-initiated COT for all FFPs in the UE or may not perform the UE-initiated COT for all FFPs in the UE.

According to the data processing method provided by the embodiment of the application, by receiving the FFP transmission pattern with the fixed frame period sent by the base station, on one hand, a plurality of FFPs allowing execution of the COT initialized by the UE can be indicated at one time through the FFP transmission pattern, so that the problem that in the prior art, the power consumption of the UE is affected because the DCI needs to be frequently demodulated to obtain whether one COT can be initialized or not can be solved, on the other hand, because the FFP allowing execution of the channel occupation time COT initialized by the UE and/or the FFP not allowing execution of the COT initialized by the UE can be indicated through the FFP transmission pattern, the problem of collision between the COT initialized by the ginitialized and the COT initialized by the UE can also be solved, and therefore, the resource utilization rate of the whole system and the throughput of the whole system can be improved.

Based on the content of the foregoing embodiment, in this embodiment, the receiving a fixed frame period FFP transmission pattern sent by a base station includes:

In this embodiment, it can be understood that there are many transmission routes of the FFP transmission pattern, including but not limited to transmission through higher layer signaling, MAC CE and GC-DCI, and thus it can be seen that, in this embodiment, the UE can receive the FFP transmission pattern transmitted by the base station through various transmission routes, and when in actual use, different transmission routes or multiple transmission routes can be selected for comprehensive use according to needs.

or the like, or, alternatively,

In this embodiment, when the base station sends the FFP transmission pattern to the UE, there may be multiple implementations, for example, one implementation is that the base station sends a first FFP transmission pattern to the UE, and all FFPs in the first FFP transmission pattern have already specified whether to allow performing the COT initialized by the UE, that is, the base station sends a certain FFP transmission pattern to the UE. In addition, another implementation manner is that the base station sends a second FFP transmission pattern to the UE, and the second FFP transmission pattern includes a part or all of FFPs that do not specify whether to allow the UE to perform the channel occupancy time COT for UE initialization, and these FFPs that do not specify whether to allow the UE to perform the channel occupancy time COT for UE initialization may be referred to as Flexible FFPs, and for these Flexible FFPs, the base station may further indicate, through DCI, whether the UE may perform the COT initialization using these Flexible FFPs.

For example, the base station may indicate through higher layer signaling/MAC CE/DCI mixing, such as: the base station may configure an initial FFP transmission pattern, where the initial FFP transmission pattern includes one or more Flexible FFPs, and then the base station sends the initial FFP transmission pattern to the UE through high-layer signaling, and the subsequent base station may further indicate, through DCI, whether the UE may use the one or more Flexible FFPs to initialize the COT.

Based on the content of the foregoing embodiments, in this embodiment, the FFP in the FFP transmission pattern that allows the UE-initialized COT to be performed and the FFP that does not allow the UE-initialized COT to be performed are distinguished by using bitmap coding.

In this embodiment, as described above, the FFP transmission pattern includes an FFP allowing the UE-initialized COT to be performed and an FFP not allowing the UE-initialized COT to be performed, and the FFP allowing the UE-initialized COT to be performed and the FFP not allowing the UE-initialized COT to be performed are distinguished by using bitmap coding.

For example, the length of the FFP transmission pattern may be set as required, and the length is the length of bitmap coding, and then 0 and 1 are used to specify whether to allow the UE-initialized COT to be executed, specifically, 1 indicates that the UE-initialized COT can be executed, and 0 indicates that the UE-initialized COT cannot be executed, so as to specify whether to allow the UE-initialized COT to be executed. For example, assuming that an FFP transmission pattern with a length of 8 bits needs to be set, and it is necessary to specify the channel occupancy time COT for which the

FFPs

1, 2, 6, and 7 allow the terminal device UE to perform initialization, and the channel occupancy time COT for which the FFPs 3, 4, 5, and 8 do not allow the terminal device UE to perform initialization, the FFP transmission pattern may be expressed by setting a bitmap of "11000110".

Based on the content of the foregoing embodiment, in this embodiment, the data processing method further includes:

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, if the FFP transmission pattern that the base station first transmits to the UE is "11000110", and it is determined that the FFP transmission pattern that needs to be transmitted to the UE is "100101" after analyzing according to actual conditions, the new FFP transmission pattern may be retransmitted to the UE at this time, which is "100101". It can be understood that, when the updated FFP transmission pattern is transmitted, it can also be transmitted through one or more of higher layer signaling, MAC CE and GC-DCI.

Based on the content of the above embodiment, in the present 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.

In this embodiment, the length of the FFP transmission pattern is variable, and the length of the FFP transmission pattern refers to the number of FFPs included in the FFP transmission pattern, and may be adjusted by setting in advance or by configuring parameters of a higher layer, for example.

Based on the content of the above embodiment, in this embodiment, the length of the FFP transmission pattern is preset or configured by a higher layer parameter.

In this embodiment, the length of the FFP transmission pattern may be adjusted by presetting or by high-layer parameter configuration, so as to meet the actual requirement. For example, the FFP transmission pattern of an appropriate length may be specified or selected when actually used by presetting the size of a plurality of fixed bits, for example, presetting a plurality of lengths such as 6 bits, 8 bits, 12 bits, etc. In addition, the FFP transmission pattern length may also be configured by higher layer parameters such as payload size.

Based on the content of the foregoing embodiment, in this embodiment, the FFP transmission pattern is based on a COT bearer initialized by a base station; or, the UE-initialized COT bearer is shared based on the base stations.

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

It is to be appreciated that the FFP transmission pattern can be based on a base station initiated COT bearer when there is a base station initiated COT. The FFP transmission pattern may be based on the base station sharing the UE-initialized COT bearer when the base station does not have the initialized COT.

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

In this embodiment, for different bearer manners corresponding to an FFP transmission pattern, the determination manner of an effective starting point of the FFP transmission pattern is different, specifically, 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 a first UE FFP after a boundary of a base station FFP where signaling is located is a reference point; wherein, the signaling is the signaling that the base station sends the FFP transmission pattern to the UE; when the FFP transmission pattern is based on a COT bearer initialized by 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 carrying the FFP transmission pattern is a reference point.

In this embodiment, for a case where FFP transmission patterns need to be sent to multiple UEs, a base station may send the FFP transmission patterns to a group of UEs using group common downlink control information GC-DCI, and when specifically sending, it needs to be noted that the FFP transmission patterns corresponding to the UEs are distinguished by using a radio Network temporary identifier rnti (radio Network temporary identity). It is to be understood that the FFP transmission pattern of each UE may be the same or different.

In this embodiment, the RNTI may be UIC-RNTI (UE-Initiated COT-RNTI). In addition, when the FFP transmission pattern is transmitted to a group of UEs using the group common downlink control information GC-DCI, the transmission may be a periodic transmission, and the period may coincide with a PDCCH monitoring period or a higher layer configuration (e.g., monitoring slot periodicity and offset).

In this embodiment, the base station further configures the starting point offset and the period of the FFP for the UE, and configuring different FFP periods for each UE mainly considers that the service, the data volume, and the allocated uplink resource and period of each UE are different; and configuring different offsets helps to reduce interference between UE transmissions, so that configuring different starting point offsets and periods for each UE is more flexible, and specifically, the reference time point of the starting point offsets may be a starting time of an FFP where a COT initialized by a base station is located, an ending time of an FFP where a COT initialized by the base station is located, a starting time of an FFP where a physical uplink control channel PUCCH that carries an acknowledgement ACK is located when there is a HARQ-ACK for HARQ-arq acknowledgement, or an ending time of an FFP where a PUCCH that carries an ACK is located when there is an HARQ-ACK for HARQ-acknowledgement.

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

Based on the content of the foregoing embodiment, in this embodiment, the starting point offset and the period are configured by the base station to the FFP of the UE through one or more of a higher layer signaling, a MAC CE, and GC-DCI.

In this embodiment, as for the offset and the period of the starting point configured for the UE by the base station, one or more of higher layer signaling, MAC CE and GC-DCI may also be used to send the UE.

In this embodiment, how to perform uplink service transmission for an FFP that does not allow execution of a UE-initialized COT in the FFP transmission pattern is described, specifically, for an FFP that does not allow execution of a UE-initialized COT in the FFP transmission pattern, the UE may perform uplink service transmission by sharing a base station-initialized COT.

determining all UE FFPs as FFPs allowing execution of UE-initialized COTs;

In this embodiment, for the case that the FFP transmission pattern transmitted by the base station is not received, any one of the following processing manners may be adopted to determine whether the FFP of the UE can allow the UE-initialized COT to be performed. For example, when the FFP transmission pattern sent by the base station is not received, the FFP of the COT allowed to perform UE initialization may be determined by using a preset or pre-stored FFP transmission pattern according to a pre-established protocol; for another example, when the FFP transmission pattern sent by the base station is not received, the FFP transmission pattern agreed in advance and the same as that of the base station may be used to determine the FFP that allows the UE-initiated COT to be performed; for another example, when the FFP transmission pattern sent by the base station is not received, all the FFPs of the UE may be determined as FFPs that allow the UE-initialized COT to be executed according to a predetermined protocol agreement; for another example, when the FFP transmission pattern transmitted by the base station is not received, all the FFPs of the UEs may be determined as FFPs that are not allowed to perform the UE-initialized COT according to a predetermined protocol convention, and so on.

As shown in fig. 3, a flowchart of steps of a data processing method applied to a base station side according to an embodiment of the present application is provided, where the method includes the following steps:

step 201: sending a fixed frame period FFP transmission pattern to terminal equipment (UE); the FFP transmission pattern comprises at least one FFP, and the FFP transmission pattern is used for indicating the FFP of the channel occupation time COT allowing the UE initialization to be executed and/or the FFP of the COT not allowing the UE initialization to be executed.

According to the data processing method provided by the embodiment of the application, the FFP transmission pattern with the fixed frame period is sent to the UE, so that on one hand, a plurality of FFPs allowing execution of the COT initialized by the UE can be indicated at one time through the FFP transmission pattern, and therefore, the problem that in the prior art, the power consumption of the UE is affected because the UE needs to frequently demodulate DCI to obtain whether the COT can be initialized or not can be solved, on the other hand, the FFP allowing execution of the channel occupation time COT initialized by the UE and/or the FFP not allowing execution of the COT initialized by the UE can be indicated through the FFP transmission pattern, and therefore, the problem of collision between the COT initialized by the gNB and the COT initialized by the UE can be solved, and therefore, the resource utilization rate of the whole system and the throughput of the whole system can be improved.

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

or the like, or, alternatively,

FFPs

In this embodiment, the length of the FFP transmission pattern may be adjusted by presetting or by high-layer parameter configuration, so as to meet the actual requirement.

For example, the FFP transmission pattern of an appropriate length may be specified or selected when actually used by presetting the size of a plurality of fixed bits, for example, presetting a plurality of lengths such as 6 bits, 8 bits, 12 bits, etc. In addition, the FFP transmission pattern length may also be configured by higher layer parameters such as payload size.

configuring an effective starting point for the FFP transmission pattern;

In this embodiment, the RNTI may be UIC-RNTI or UE-Initiated COT-RNTI. In addition, when the FFP transmission pattern is transmitted to a group of UEs using the group common downlink control information GC-DCI, the transmission may be a periodic transmission, and the period may coincide with a PDCCH monitoring period or a higher layer configuration (e.g., monitoring slot periodicity and offset).

configuring a starting point offset and a period for the FFP of the UE;

Based on the content of the foregoing embodiment, in this embodiment, the starting point offset and the period are indicated by one or more of a higher layer signaling, a MAC CE and GC-DCI.

The present application will be specifically described below with reference to specific examples.

The first embodiment:

in this embodiment, the gNB indicates an FFP to transmit a pattern through higher layer signaling/MAC CE/so that the UE can know which FFPs can execute the UE-initiated COT (Channel allocation time) and which FFPs cannot execute the UE-initiated COT according to the pattern. For those COTs for which the UE is not allowed to initialize, the UE can perform transmission of UL traffic using the gNB-initialized COT. If the base station does not configure transmission pattern, the default UE and base station patterns may be the same or for all FFPs, the UE may perform UE-initiated COT or for all FFPs, the UE may not perform UE-initiated COT.

The FFP transmission pattern where the UE-initiated COT is located may indicate a bit in a bitmap manner to indicate whether a group of FFPs of the UE can execute the UE-initiated COT, 1 indicates that the UE-initiated COT can be executed, and 0 indicates that the UE-initiated COT cannot be executed. The transmission pattern may be used periodically or N FFP transmission patterns are predefined, one of the patterns is indicated by an a ═ ceil (log2N) bit, and the gNB may modify the transmission pattern through the higher layer signaling/MAC CE, and the bitmap of the transmission pattern may be variable (configurable through a higher layer parameter) or a fixed bit size is agreed in advance. The bitmap indicated by the transmission pattern based on the MAC CE bearer is shown in fig. 4. Fig. 4 is only a schematic diagram of a specific bitmap length, and a network can be configured according to an actual situation. In fig. 4, the bitmap length is set to 8 bits to indicate 8 FFPs, and the transmission pattern of FFP is also repeated in a cycle of 8 FFPs. Fig. 5 is a diagram illustrating RRC high layer signaling carrying transmission pattern indication information bitmap. In fig. 5, the Payloadsize parameter has N bits, and its value range is [0, M ], the specific value of the Payloadsize parameter indicates the bit length of the FFP bitmap, and the network sets the UE transmission pattern by using the bit length of the Payloadsize. If the network does not configure the FFP transmission pattern through the higher layer signaling/MAC CE, the default transmission pattern of the UE may be the same as the pattern of the base station or for all FFPs, the UE may perform the UE-initiated COT or for all FFPs, the UE may not perform the UE-initiated COT. As shown in fig. 6 and 7, the gNB may carry the transmission pattern of the UE-initiated COT in two ways. One is a transmission pattern based on the gNB shared UE-initialized COT to carry the UE-initialized COT (as shown in FIG. 6), and the other is a gNB shared UE-initialized COT to carry the UE-initialized COT (as shown in FIG. 7).

In addition, as shown in fig. 8, the gNB may update the UE-initiated COT transmission pattern according to the network status, where the update may be periodic or dynamic. May pass through higher layer signaling/MAC CE/DCI. The UE-initiated COT transmission pattern update can be carried based on gNB-initiated COT bearing or gNB sharing UE-initiated COT bearing. In addition, the gNB indicates through higher layer signaling/MAC CE/DCI mixing, for example: the gNB can configure an initial pattern, which includes some Flexible FFPs, and then indicate whether the Flexible FFPs are available through the MAC/CE or the DCI by the gNB. In this case, the gNB may send an optional pattern list to the UE, indicating one pattern through the MAC CE/DCI. If the pattern has a Flexible FFP, the gNB further indicates, through the DCI, whether the UE can perform initialization of a COT using the FFP.

In addition, the effective starting point of the pattern transmission for the FFP is the first FFP of UE after the boundary of the base station FFP where the signaling is located is the reference point. As shown in fig. 9 and fig. 10, the effective starting point of the FFP transmission pattern is the boundary of the FFP carrying the FFP transmission pattern, and the FFP for the UE-initiated COT, which is closest in time to the boundary, starts to perform the transmission pattern.

In addition, for the FFP where the UE-initiated COT is located, the gNB configures a start point offset and a period for the FFP (fix frame period) of each UE through higher layer signaling/MAC CE/DCI, and if not configured, the start point and the period are the same as the COT initiated by the gNB by default or the UE can initiate a COT. As shown in fig. 11 and 12, there are two ways to reference the starting point of the FFP of the UE, one is to use the starting time of the FFP where the gNB-initiated COT is located as the reference time point, and the other is to use the ending time of the FFP where the gNB-initiated COT is located as the reference time point. Or may take effect after HARQ-ACK reply (ACK) if there is HARQ-ACK feedback; specifically, the start time or the end time of the FFP in which the PUCCH carrying ACK is located may be determined.

Referring to fig. 13, fig. 14 and table 1, the gNB may indicate the offset and the period of the FFP where the UE-initiated and COT is located through RRC/MAC CE/DCI, or may indicate the offset and the period through a combination of the above 3 methods. For example: the offset and period of the UE FFP are initially configured by RRC and updated by MAC CE/DCI. Or the offset and the period of a group of UE FFPs are broadcasted by RRC, and the offset and the period of a specific FFP are indicated by MAC CE/DCI. The period of the FFP may be configured with reference to the PUSCH period of the CG of the UE, and if the UE configures PUSCH of multiple CGs, the gNB can select one period as a reference. If the FFP period of the UE is less than the period of the gNB, the gNB may configure the FFP periods of a plurality of UEs to be equal to the period of one gNB FFP, so that the FFP and the period of the FFP of the UE may be configured more flexibly and simply.

Second embodiment:

the present embodiment is mainly that the gNB indicates a group of UEs through a group common DCI (GC-DCI) (as shown in table 2 below). If a set of UEs is indicated using the GC-DCI, a new (UIC-RNTI, UE-Initiated COT-RNTI) is used, which may be a periodic transmission, a period may coincide with a PDCCH monitoring period or a higher layer configuration, and time and frequency domain resources may use a higher layer indication (timefrequency region). The same transmission pattern can be configured for a plurality of UEs, and different patterns can also be configured, wherein the patterns are indicated by bitmap, and the length of the bitmap has high-level indication. As shown in fig. 15, transmission patterns of 2 UEs are indicated in the GC-DCI, and the legacy patterns of the two UEs are different.

UEj Transmission Pattern	Nj

In addition, the period may be consistent with the PDCCH monitoring period or configured in a higher layer (monitoring slot periodicity and offset), the gNB may also allocate a core set (control resource set) to the GC-DCI of the transmission pattern of the UE-Initiated COT, and the UE may search the GC-DCI of the transmission pattern of the UE-Initiated COT on the core set by using the UIC-RNTI, as shown in fig. 16.

It can be understood that, in the embodiment of the present application, by introducing the FFP pattern transmission mechanism for UE-initiated COT controlled by the gNB, the resource utilization rate and the throughput of the entire system can be improved, and the number of times for UE blind detection DCI is reduced, thereby reducing the power consumption of the UE.
