Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a resource control method, information transmission method, apparatus, terminal and base station. Background Technology

[0002] To address the high latency and reliability requirements of URLLC (Ultra-Reliable and Low-Latency Communications) services, 5G systems introduce the PDCP (Packet Data Convergence Protocol) retransmission mechanism. This mechanism transmits the same PDCP layer PDU (Protocol Data Unit) through multiple paths, thereby improving transmission reliability and reducing transmission latency through multi-path transmission gain.

[0003] However, for services with strict latency and reliability requirements, the loss of one data packet necessitates the correct transmission of subsequent data packets. To enable the base station to promptly send retransmission activation commands and allocate uplink resources, the base station allocates pre-configured resources for the terminal on the CC (Component Carrier) corresponding to the secondary RLC (RadioLink Control). The terminal directly uses these pre-configured resources when activating a specific RLC entity to participate in PDCP retransmission. However, in existing technologies, these pre-configured resources are configured and activated by the base station. Once the base station activates the pre-configured resource for the terminal, it remains in effect. For PDCP retransmissions or new RLC entities activated by the terminal itself, the pre-configured resources remain unused by the terminal until the RLC entity participates in PDCP retransmission, resulting in significant resource waste. Summary of the Invention

[0004] The purpose of this invention is to provide a resource control method, information transmission method, apparatus, terminal, and base station to solve the problem of resource waste that exists before a terminal-activated PDCP repeated transmission or a new RLC entity participates in PDCP repeated transmission.

[0164] In this embodiment of the invention, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0165] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0166] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0167] To facilitate understanding of the methods in the embodiments of this application, the prior art will be briefly described first.

[0168] The maximum number of repeated transmission paths for the currently introduced PDCP is four. This includes one radio bearer at the PDCP layer (corresponding to one PDCP entity), and transmission at the RLC layer via multiple logical channels (each logical channel corresponding to one RLC entity).

[0169] In the PDCP retransmission model under CA (Carrier aggregation), the multiple logical channels corresponding to the retransmitted radio bearers are processed by a single MAC entity at the MAC (Media Access Control) layer. In the PDCP retransmission model under DC (Dual connectivity), the logical channels corresponding to different nodes (MN (Master Node) or SN (Secondary Node)) are mapped to their respective MAC entities for processing.

[0170] Before PDCP retransmission activation, the RLC entity that transmits Radio Bearer (RB) data is called the primary RLC entity, and the corresponding logical channel is called the primary logical channel. This logical channel cannot be deactivated. After PDCP retransmission activation, the RLC entity used to transmit replicated PDCP PDUs is called the secondary RLC entity, and the corresponding logical channel is called the secondary logical channel.

[0171] In existing technologies, uplink DRB (Data Radio Bearer) PDCP retransmission is activated and deactivated by the base station. When the base station activates PDCP retransmission or activates a new RLC entity, if the secondary RLC entity has data, it will allocate uplink resources to the secondary RLC entity to realize the actual execution of uplink DRB PDCP retransmission.

[0172] However, for services with strict latency and reliability requirements, when a data packet is lost, subsequent data packets must be transmitted correctly. If the base station cannot promptly send a retransmission activation command and allocate uplink resources, the terminal needs to autonomously activate PDCP retransmission or a new RLC entity participating in PDCP retransmission. However, when the terminal autonomously activates PDCP retransmission or a new RLC entity, the base station cannot be aware of this activation and cannot allocate resources to the auxiliary RLC entity in a timely manner. This results in the terminal being unable to actually perform uplink PDCP retransmission after autonomously activating PDCP retransmission or a new RLC entity.

[0173] To address this issue, the existing solution is for the base station to allocate pre-configured resources to the terminal on the CC corresponding to the secondary RLC. When the terminal activates a specific RLC entity to participate in PDCP retransmission, it directly uses these pre-configured resources.

[0174] 5G system uplink pre-configured resources include two types: CG type 1 (configuration authorization type 1) and CG type 2 (configuration authorization type 2). CG type 1 is when the base station pre-configures uplink resources, it directly allocates the period, starting point, time and frequency domain resources and transmission format (such as MCS, RV version) of the pre-configured resources. After the base station sends the RRC (Radio Resource Control) command to configure CG type 1, the pre-configured resources are directly effective on the base station and the terminal side.

[0175] CG type 2 means that when the base station pre-configures uplink resources, it only configures the pre-configured resource period. The base station then uses PDCCH (Physical Downlink Control Channel) scheduling commands to activate and deactivate CG type 2. In the activation PDCCH, the starting point, time and frequency domain resources and transmission format (such as MCS, RV version) of the pre-configured resources are allocated.

[0176] Obviously, both types of pre-configured resources are configured and activated by the base station. Once the base station activates the pre-configured resource for the terminal, the pre-configured resource remains effective. For new RLC entities activated by the terminal itself, the pre-configured resources of the cell corresponding to the RLC entity are in a state where the terminal does not actually use them before the RLC entity participates in PDCP repeated transmission, which will cause a lot of resource waste.

[0177] To address the aforementioned issues, embodiments of this application provide a resource control method, an information transmission method, and an apparatus. The method and apparatus are based on the same concept. Since the methods and apparatus solve problems in similar ways, their implementations can be mutually referenced, and repeated details will not be elaborated upon.

[0178] like Figure 1 The diagram shown is a flowchart of a resource control method provided in an embodiment of the present invention, applied to a terminal, and includes:

[0179] Step 101: The terminal receives configuration information of pre-configured resources sent by the base station. The configuration information includes: pre-configured resource period, time-frequency domain resource information, and transmission format.

[0180] Optionally, in this step, the terminal receives RRC signaling sent by the base station, wherein the RRC signaling includes configuration information of pre-configured resources.

[0181] A pre-configured resource cycle may include one or more pre-configured resources.

[0182] Step 102: The terminal activates or deactivates the pre-configured resources.

[0183] Here, "activating pre-configured resources" means making the pre-configured resources available so that the terminal can use them.

[0184] Deactivating pre-configured resources on the terminal means making the pre-configured resources unavailable, so that the terminal cannot use the pre-configured resources.

[0185] It should be noted that before the terminal activates the pre-configured resources, the initial activation state of the pre-configured resources is deactivated. This initial activation state can be carried in the configuration information or specified by the protocol. Thus, when the terminal autonomously activates PDCP retransmission or activates a new RLC entity to participate in PDCP retransmission, the terminal can immediately have uplink resources available by autonomously activating the pre-configured resources, avoiding resource waste.

[0186] When the terminal does not need to use uplink resources, it can automatically activate the pre-configured resources, that is, immediately stop using uplink resources, thereby avoiding waste of resources.

[0187] The resource control method of this invention involves a terminal receiving configuration information of pre-configured resources sent by a base station. This configuration information includes: pre-configured resource period, time-frequency domain resource information, and transmission format. The terminal activates or deactivates the pre-configured resources. In this way, when the terminal autonomously activates PDCP repeated transmission or activates a new RLC entity to participate in PDCP repeated transmission, it can immediately have uplink resources available. Alternatively, by deactivating the pre-configured resources allocated by the base station, the terminal can immediately stop using uplink resources when they are not needed, thereby avoiding resource waste.

[0188] Optionally, the time-frequency domain resource information includes time slot occupancy and frequency domain resource occupancy; or, the time-frequency domain resource information includes time slot occupancy and frequency domain resource occupancy, as well as the start time point of the pre-configured resources.

[0189] It should be noted that, when the time-frequency domain resource information includes time slot occupancy and frequency domain resource occupancy, the start time point of the pre-configured resources is determined by the terminal UE.

[0190] Given that the time-frequency domain resource information includes time slot occupancy and frequency domain resource occupancy, as well as the start time point of the pre-configured resources, the specific transmission time-frequency domain resources and transmission format of the first pre-configured resource can be determined, and subsequent pre-configured resources can be periodically repeated according to the pre-configured resource cycle.

[0191] Optionally, the configuration information further includes at least one of the following:

[0192] The number of pre-configured resources in each of the pre-configured resource cycles;

[0193] The initial activation state of pre-configured resources;

[0194] The first indication information regarding whether the pre-configured resources can be activated by the terminal;

[0195] The second indication information regarding whether the pre-configured resources can be deactivated by the terminal;

[0196] Configuration of the first physical uplink control channel (PUCCH) carrying the terminal activation resource indication;

[0197] The bearer terminal deactivates the second PUCCH configuration of the resource indicator;

[0198] The first time interval between the moment when the terminal sends the activation resource indication and the moment when the first uplink resource of the activated pre-configured resource becomes effective;

[0199] The second time interval between the moment when the terminal sends the deactivation resource indication and the moment when the deactivation resource indication takes effect.

[0200] Here, the initial activation status of pre-configured resources includes two states: activated or deactivated.

[0201] It should be noted that if the first indication information indicates that the pre-configured resource cannot be activated by the terminal, it means that the domain configuration cannot be activated or deactivated by the terminal. In this case, it will fall back to the CG type 1 configuration method, that is, the configuration information of the pre-configured resource includes the start time point, time slot occupation, frequency domain resource occupation and transmission format of the pre-configured resource.

[0202] When the time-frequency domain resource information includes time slot occupancy and frequency domain resource occupancy, the time-frequency domain resource information configured by the base station does not include the start time point of the pre-configured resources. The start time point of the pre-configured resources needs to be obtained in another way. One way is that the base station's configuration information includes a first time interval between the time when the terminal sends the activation resource indication and the effective time of the first uplink resource of the activated pre-configured resource. In this way, the terminal can determine the start time point of activating the pre-configured resources based on the first time interval.

[0203] Here, the moment when the first uplink resource becomes effective refers to the moment when the first uplink resource is in an available state.

[0204] Optionally, when the configuration information includes a first physical uplink control channel (PUCCH) configuration carrying a terminal activation resource indication, the activation resource indication sent through the first PUCCH configuration includes a pre-configured resource number for terminal activation; or, the first PUCCH configuration includes multiple sets of PUCCH resource configuration information, with different PUCCH resources corresponding to different pre-configured resource numbers.

[0205] In other words, the pre-configured resource number (CG ID) can be explicitly represented, i.e., included in the activation resource indication information. The terminal can use a bit value to represent the activated pre-configured resource number (CG ID) in the activation resource indication signaling. Alternatively, the activated pre-configured resource number (CG ID) can be implicitly represented, i.e., different PUCCH resources correspond to different pre-configured resource numbers. The base station and the terminal can determine the activated pre-configured resource number (CG ID) by sending activation resource indications on different PUCCH resources.

[0206] Here, the terminal activation resource indication can be an SR (Scheduling Request) command carried on the PUCCH, or a separate activation pre-configured resource indication command.

[0207] Optionally, when the configuration information includes a second PUCCH configuration that carries a terminal deactivation resource indication, the deactivation resource indication sent through the second PUCCH configuration includes a pre-configured resource number for terminal deactivation; or, the second PUCCH configuration includes multiple sets of PUCCH resource configuration information, with different PUCCH resources corresponding to different pre-configured resource numbers.

[0208] In other words, the pre-configured resource number (CG ID) indicating deactivation can be explicitly represented, i.e., included in the deactivation resource indication information. The terminal can represent the activated pre-configured resource number (CG ID) using a bit value in the activation resource indication signaling. Alternatively, the pre-configured resource number (CG ID) indicating deactivation can be implicitly represented, i.e., different PUCCH resources correspond to different pre-configured resource numbers. The base station and the terminal can determine the deactivated pre-configured resource number (CG ID) by sending deactivation resource indications on different PUCCH resources.

[0209] Here, the terminal deactivation resource indication can be an SR command carried on the PUCCH, or a standalone deactivation pre-configured resource indication command.

[0210] As an optional implementation, when the time-frequency domain resource information includes time slot occupancy and frequency domain resource occupancy, as well as the start time point of the pre-configured resources, the terminal activates the pre-configured resources, including:

[0211] Send an activation resource indication to the base station, the activation resource indication being used to instruct the terminal to activate the pre-configured resources starting from the start point of the next pre-configured resource cycle after the activation resource indication;

[0212] In other words, the terminal sends an activation resource indication on the PUCCH resource, indicating that the pre-configured resources allocated by the base station will be activated starting from the next pre-configured resource cycle. For a detailed illustration of activating pre-configured resources, please refer to [link to relevant documentation]. Figure 2In the diagram, dashed lines represent deactivation, and solid lines represent activation.

[0213] Alternatively, the activation resource indication may be used to instruct the terminal to start activating pre-configured resources from the next available pre-configured resource following the activation resource indication.

[0214] It should be noted that when the number of pre-configured resources in the pre-configured resource cycle is greater than or equal to two, that is, multiple, the activation resource indication can be used to instruct the terminal to start activating the pre-configured resource from the next available pre-configured resource after the activation resource indication.

[0215] In other words, if there are multiple consecutive resource allocations within a pre-configured resource period, the terminal sends an activation resource indication on the PUCCH resource, instructing the terminal to use the available resources from the consecutive resources of a specific period, and to activate the pre-configured resources starting from that period. For a detailed illustration of activating pre-configured resources, please refer to [link to relevant documentation]. Figure 3 .

[0216] Here, the terminal sends an activation resource indication to the base station, which can also serve as an explicit notification to the base station that the terminal has activated the pre-configured resources allocated by the base station.

[0217] As an optional implementation, when the time-frequency domain resource information includes time slot occupancy and frequency domain resource occupancy, and a first time interval between the time when the terminal sends the activation resource indication and the effective time of the first uplink resource of the activated pre-configured resource, the method of this embodiment may further include:

[0218] After sending an activation resource instruction to the base station, the first uplink resource to be activated at the first target time starting point is determined according to the first time interval.

[0219] In this step, after sending the activation resource indication, the terminal adds the first time interval to the time of sending the activation resource indication as the first target time starting point for activating the pre-configured resources. Then, based on the time slot occupancy, frequency domain resource occupancy, and transmission mode indicated by the base station's pre-configuration, the pre-configured resources are activated for uplink transmission. For a detailed illustration of activating pre-configured resources, please refer to [link to relevant documentation]. Figure 4 .

[0220] As another optional implementation, when the time-frequency domain resource information includes time slot occupancy and frequency domain resource occupancy, the method of this embodiment of the invention may further include:

[0221] After sending an activation resource indication to the base station, the first uplink resource of the pre-configured resource is activated at the third target time starting point according to the third time interval, wherein the third time interval is specified by the protocol or carried in the activation resource indication.

[0222] In this step, after the terminal sends the activation resource indication, it adds the time of sending the activation resource indication to the third time interval to obtain the time point as the third target time starting point for activating the pre-configured resources. Then, based on the time slot occupation, frequency domain resource occupation and transmission mode of the base station pre-configuration indication, the pre-configured resources are activated for uplink transmission.

[0223] The difference between this implementation and the previous one is that the third time interval is specified by the protocol or carried in the activation resource instruction.

[0224] As another optional implementation, when the time-frequency domain resource information includes time slot occupancy and frequency domain resource occupancy, as well as the start time point of the pre-configured resources, the terminal activates the pre-configured resources, including:

[0225] The terminal uses the pre-configured resources to send uplink transmission data.

[0226] This step describes how the terminal autonomously uses the most recently pre-configured resources, starting with the uplink resources used by the terminal, to activate those pre-configured resources.

[0227] Optionally, the time-frequency domain resource information of the pre-configured resource includes time slot occupancy and frequency domain resource occupancy, as well as the start time point of the pre-configured resource.

[0228] On the base station side, when the base station detects that the terminal is using pre-configured resources to send uplink data, which can also be understood as detecting that the terminal has used pre-configured resources for a specific period, it determines to activate the uplink resources allocated by the base station starting from those pre-configured resources. For a detailed illustration of activating pre-configured resources, please refer to [link to relevant documentation]. Figure 5 .

[0229] Here, the terminal uses pre-configured resources to send uplink transmission data. The base station detects that the terminal has used the pre-configured resources. This method serves as an implicit notification, allowing the base station to proactively learn that the terminal has activated the pre-configured resources allocated by the base station.

[0230] As another optional implementation, when the time-frequency domain resource information includes time slot occupancy and frequency domain resource occupancy, as well as the start time point of the pre-configured resources, the terminal activates the pre-configured resources, including:

[0231] The terminal receives the Packet Data Convergence Protocol (PDCP) retransmission activation command sent by the base station and activates the pre-configured resources on the first cell, which is the cell corresponding to the Radio Link Control (RLC) entity activated by the PDCP retransmission activation command during PDCP retransmission.

[0232] In this step, the PDCP retransmission activation command sent by the base station implicitly instructs the terminal to activate the pre-configured resources. For a detailed illustration of activating pre-configured resources, please refer to [link to relevant documentation]. Figure 6 .

[0233] It should be noted that the first cell can be called SCell (Secondary Cell) or CC.

[0234] Here, the PDCP repeat transfer activation command is Duplication Activation / Deactivation MAC CE or Duplication RLC Activation / Deactivation MAC CE.

[0235] Here, the PDCP retransmission activation command is used to activate PDCP retransmission. Correspondingly, it is necessary to activate the RLC entity participating in PDCP retransmission. Data packets on this RLC entity can only be transmitted on the cell corresponding to this RLC entity.

[0236] It should be noted that the above three methods for activating pre-configured resources on the terminal are parallel solutions.

[0237] As an optional implementation, when the time-frequency domain resource information includes time slot occupancy and frequency domain resource occupancy, as well as the start time point of the pre-configured resources, the terminal deactivates the pre-configured resources, including:

[0238] Send a first deactivation resource indication to the base station. The first deactivation resource indication is used to instruct the terminal to deactivate the pre-configured resource starting from the start point of the next pre-configured resource period after the deactivation resource indication; or, the first deactivation resource indication is used to instruct the terminal to deactivate the pre-configured resource starting from the next available pre-configured resource after the deactivation resource indication.

[0239] Here, the first deactivation resource instruction corresponds to the activation resource instruction sent by the terminal to the base station in the above embodiment.

[0240] Based on this, as an optional implementation, before sending the first deactivation resource indication to the base station, the method further includes:

[0241] The terminal needs to activate the pre-configured resources if one of the following conditions is met:

[0242] PDCP retransmissions transmitted on the pre-configured resources are deactivated;

[0243] The terminal stops using the pre-configured resources.

[0244] Here, the terminal stops using the pre-configured resource, meaning that no further data is transmitted on the pre-configured resource from the terminal side.

[0245] As another optional implementation, the terminal deactivates the pre-configured resources, including:

[0246] The terminal receives a second deactivation resource indication sent by the base station, and deactivates the pre-configured resource according to the second deactivation resource indication;

[0247] Here, the second deactivation resource indication can be indicated by the DCI (Downlink Control Information) carried by the PDCCH, or by the downlink MAC CE indication.

[0248] As another optional implementation, the terminal deactivates the pre-configured resources, including:

[0249] The terminal receives the PDCP retransmission deactivation command sent by the base station and deactivates the pre-configured resources on the second cell, which is the cell corresponding to the RLC entity deactivated by the PDCP retransmission deactivation command during PDCP retransmission.

[0250] Here, the PDCP repeat transmission deactivation command corresponds to the PDCP repeat transmission activation command in the above embodiment.

[0251] It should be noted that the PDCP retransmission deactivation command is used to deactivate PDCP retransmission. Correspondingly, it is necessary to deactivate the RLC entity corresponding to the cell that participates in PDCP retransmission.

[0252] As an optional implementation, if the configuration information includes a second time interval between the time when the terminal sends the deactivation resource indication and the time when the deactivation resource indication takes effect, the method further includes:

[0253] After sending a deactivation resource indication to the base station, the deactivation resource indication is determined to take effect at a second target time starting point based on the second time interval.

[0254] In this step, after the terminal sends the deactivation resource instruction, it adds the second time interval to the time when the deactivation resource instruction was sent as the second target time starting point for the deactivation instruction to take effect. That is, starting from the second target time starting point, all subsequent pre-configured resources are deactivated.

[0255] Here, "deactivate resource instruction taking effect" specifically means that the terminal executes the function corresponding to the deactivate resource instruction, that is, executes resource deactivation. In other words, from the moment the deactivate resource instruction takes effect, all subsequent pre-configured resources are deactivated.

[0256] As an optional implementation, before the terminal activates or deactivates the pre-configured resources, the method further includes:

[0257] The terminal needs to activate the pre-configured resources if one of the following conditions is met:

[0258] The terminal activation enables the transmission of repeatedly transmitted data packets via Packet Data Convergence Protocol (PDCP) on the pre-configured resources.

[0259] The terminal transmits specific service data on the pre-configured resources.

[0260] It should be noted that specific service data can be data from RBs or logical channels specified by the base station or core network.

[0261] In the above implementation methods, the pre-configured resources are activated or deactivated autonomously by the terminal. Of course, the base station can also activate the pre-configured resources as needed. Specifically, as an optional implementation method, the following are also included:

[0262] The base station receives a third deactivation resource indication, which instructs the base station to deactivate the pre-configured resource starting from the beginning of the next pre-configured resource period after the third deactivation resource indication, or the third deactivation resource indication instructs the base station to deactivate the pre-configured resource starting from the next available pre-configured resource after the third deactivation resource indication.

[0263] The resource control method of this invention involves a terminal receiving configuration information of pre-configured resources sent by a base station. This configuration information includes: pre-configured resource period, time-frequency domain resource information, and transmission format. The terminal activates or deactivates the pre-configured resources. In this way, when the terminal autonomously activates PDCP repeated transmission or activates a new RLC entity to participate in PDCP repeated transmission, it can immediately have uplink resources available. Alternatively, by deactivating the pre-configured resources allocated by the base station, the terminal can immediately stop using uplink resources when they are not needed, thereby avoiding resource waste.

[0264] like Figure 7 The diagram shown is a flowchart of an information transmission method provided in an embodiment of the present invention, applied to a base station, and includes:

[0265] Step 701: The base station sends configuration information of pre-configured resources to the terminal. The configuration information includes: pre-configured resource period, time-frequency domain resource information and transmission format.

[0266] In this step, specifically, the base station sends RRC signaling to the terminal, and the RRC signaling includes configuration information of pre-configured resources. In other words, the base station sends the configuration information of pre-configured resources to the terminal via RRC signaling.

[0267] A pre-configured resource cycle may include one or more pre-configured resources.

[0268] Here, the base station sends configuration information of pre-configured resources to the terminal, so that the terminal has resources that can be activated when it needs to activate or deactivate the resources required for transmitting uplink data. Thus, when the terminal autonomously activates PDCP retransmission or activates a new RLC entity to participate in PDCP retransmission, it can immediately use uplink resources by autonomously activating the pre-configured resources. When the terminal does not need to use uplink resources, it can autonomously deactivate the pre-configured resources, that is, immediately stop using uplink resources, thereby avoiding resource waste.

[0269] In the information transmission method of this invention, the base station sends configuration information of pre-configured resources to the terminal. The configuration information includes: pre-configured resource period, time-frequency domain resource information, and transmission format. This enables the base station to provide the terminal with resources that can be activated or deactivated by the terminal. When the terminal autonomously activates PDCP repeated transmission or activates a new RLC entity to participate in PDCP repeated transmission, the terminal can immediately use uplink resources by autonomously activating the pre-configured resources. When the terminal does not need to use uplink resources, it can autonomously deactivate the pre-configured resources, that is, immediately stop using uplink resources, thereby avoiding resource waste.

[0270] Optionally, the time-frequency domain resource information includes time slot occupancy and frequency domain resource occupancy; or, the time-frequency domain resource information includes time slot occupancy and frequency domain resource occupancy, as well as the start time point of the pre-configured resources.

[0271] Optionally, the configuration information further includes at least one of the following:

[0272] The number of pre-configured resources in each of the pre-configured resource cycles;

[0273] The initial activation state of pre-configured resources;

[0274] The first indication information regarding whether the pre-configured resources can be activated by the terminal;

[0275] The second indication information regarding whether the pre-configured resources can be deactivated by the terminal;

[0276] Configuration of the first physical uplink control channel (PUCCH) carrying the terminal activation resource indication;

[0277] The bearer terminal deactivates the second PUCCH configuration of the resource indicator;

[0278] The first time interval between the moment when the terminal sends the activation resource indication and the moment when the first uplink resource of the activated pre-configured resource becomes effective;

[0279] The second time interval between the moment when the terminal sends the deactivation resource indication and the moment when the deactivation resource indication takes effect.

[0280] When the time-frequency domain resource information includes time slot occupancy and frequency domain resource occupancy, since the base station has not configured the start time point of the pre-configured resources, the configuration information needs to include a first time interval between the time when the terminal sends the activation resource indication and the effective time of the first uplink resource of the activated pre-configured resource. In this way, the subsequent terminal can determine the start time point of activating the pre-configured resource based on the first time interval.

[0281] As an optional implementation, if the time-frequency domain resource information includes time slot occupancy and frequency domain resource occupancy, as well as the start time point of the pre-configured resources, it further includes:

[0282] The terminal receives an activation resource indication, which instructs the terminal to activate pre-configured resources starting from the beginning of the next pre-configured resource cycle after the activation resource indication; or, the activation resource indication instructs the terminal to activate pre-configured resources starting from the next available pre-configured resource after the activation resource indication.

[0283] Here, the base station receives the activation resource instruction sent by the terminal, which serves as an explicit notification, indicating that the terminal has activated the pre-configured resources allocated by the base station.

[0284] As an optional implementation, embodiments of the present invention further include:

[0285] If it is detected that the terminal is using the pre-configured resources to send uplink transmission data, it is determined that the terminal has activated the pre-configured resources.

[0286] In this step, the base station actively detects that the terminal is using pre-configured resources to send uplink data, thus determining that the terminal has activated the pre-configured resources allocated by the base station starting from this point. In this way, the base station implicitly learns that the terminal has activated the pre-configured resources.

[0287] As an optional implementation, the method in this embodiment of the invention further includes:

[0288] Send a PDCP retransmission activation command to the terminal and activate the pre-configured resources on the first cell, where the first cell is the cell corresponding to the RLC entity activated by the PDCP retransmission activation command during PDCP retransmission.

[0289] In this step, the PDCP retransmission activation command sent by the base station implicitly instructs the terminal to activate the pre-configured resources. It should be noted that this PDCP retransmission activation command also causes the base station to activate the pre-configured resources on the first cell.

[0290] It should be noted that the first cell can be referred to as SCell or CC.

[0291] Here, the PDCP repeat transfer activation command is Duplication Activation / Deactivation MAC CE or Duplication RLC Activation / Deactivation MAC CE.

[0292] As an optional implementation, when the time-frequency domain resource information includes time slot occupancy and frequency domain resource occupancy, as well as the start time point of the pre-configured resources, the method of this embodiment further includes:

[0293] The receiving terminal sends a first deactivation resource indication, which is used to instruct the terminal to deactivate the pre-configured resource starting from the start point of the next pre-configured resource cycle after the deactivation resource indication; or, the first deactivation resource indication is used to instruct the terminal to deactivate the pre-configured resource starting from the next available pre-configured resource after the deactivation resource indication.

[0294] As another optional implementation, the method in this embodiment of the invention further includes:

[0295] Send a second deactivation resource instruction to the terminal so that the terminal deactivates the pre-configured resource according to the second deactivation resource instruction;

[0296] Here, the second deactivation resource indication can be indicated by the DCI (Downlink Control Information) carried by the PDCCH, or by the downlink MAC CE indication.

[0297] As another optional implementation, the method in this embodiment of the invention further includes:

[0298] A PDCP retransmission deactivation command is sent to the terminal so that the terminal deactivates the pre-configured resources on the second cell according to the PDCP retransmission deactivation command. The second cell is the cell corresponding to the RLC entity deactivated by the PDCP retransmission deactivation command during PDCP retransmission.

[0299] As an optional implementation, the method in this embodiment of the invention further includes:

[0300] A third deactivation resource indication is sent to the terminal. The third deactivation resource indication is used to instruct the base station to deactivate the pre-configured resource starting from the start point of the next pre-configured resource period after the third deactivation resource indication, or the third deactivation resource indication is used to instruct the base station to deactivate the pre-configured resource starting from the next available pre-configured resource after the third deactivation resource indication.

[0301] In this step, the base station activates the pre-configured resources and then sends a third deactivation resource instruction to notify the terminal.

[0302] In the information transmission method of this invention, the base station sends configuration information of pre-configured resources to the terminal. The configuration information includes: pre-configured resource period, time-frequency domain resource information, and transmission format. This enables the base station to provide the terminal with resources that can be activated or deactivated by the terminal. When the terminal autonomously activates PDCP repeated transmission or activates a new RLC entity to participate in PDCP repeated transmission, the terminal can immediately use uplink resources by autonomously activating the pre-configured resources. When the terminal does not need to use uplink resources, it can autonomously deactivate the pre-configured resources, that is, immediately stop using uplink resources, thereby avoiding resource waste.

[0303] The implementation process of the method of the present invention will be described below from the perspective of the interaction between the terminal and the base station.

[0304] Example 1: The base station allocates pre-configured resources, and the terminal autonomously activates and deactivates the pre-configured resources. See [link to example]. Figure 8

[0305] Step 1: The base station sends RRC signaling to the terminal. The RRC signaling includes configuration information of the pre-configured resources allocated by the base station to the terminal. The configuration information includes the pre-configured resource period, time slot occupation and frequency domain resource occupation, transmission format, time start of the pre-configured resources, the initial state of the pre-configured resources being deactivated, and multiple pre-configured resources in a pre-configured resource period.

[0306] Step 2: The terminal receives the RRC signaling sent by the base station;

[0307] Step 3: When the terminal determines that it wants to activate the pre-configured resource, it sends an activation resource instruction to the base station.

[0308] Here, the criteria for the terminal to determine whether to activate the pre-configured resource are: the terminal voluntarily activates PDCP retransmission that can be transmitted on the pre-configured resource, or the terminal's specific service data arrives and needs to be transmitted on the pre-configured resource (the specific service data can be data from an RB or logical channel specified by the base station or core network). Afterwards, starting from the beginning of the first pre-configured resource period after sending the activation resource indication, the terminal activates the pre-configured resource and uses it to transmit uplink data.

[0309] Step 4: The base station receives the activation resource instruction sent by the terminal.

[0310] Here, the terminal activates the pre-configured resources starting from the beginning of the next pre-configuration period indicated by the instruction, and the base station receives uplink transmission data on the pre-configured resources.

[0311] Step 5: When the terminal determines that it needs to deactivate the pre-configured resources, it sends a deactivation resource instruction to the base station.

[0312] Here, the terminal determines whether to deactivate the pre-configured resource based on the following criteria: either the repeated PDCP transmissions on the pre-configured resource are deactivated, or no subsequent data is transmitted on the pre-configured resource. The terminal then begins deactivating the pre-configured resource from the start of the first pre-configured resource cycle following the deactivation instruction.

[0313] Step 6: The base station receives the deactivation resource instruction sent by the terminal.

[0314] Here, the terminal deactivates the pre-configured resource starting from the beginning of the next pre-configuration cycle indicated by the instruction, and the base station no longer receives uplink transmission data on the pre-configured resource.

[0315] It should be noted that the initial state of the pre-configured resources in this embodiment is deactivated.

[0316] If the base station configuration information indicates that the initial state of the pre-configured resource is active, the terminal can directly use the pre-configured resource; afterwards, it can also send an instruction to deactivate the pre-configured resource to deactivate it.

[0317] Example 2: The base station allocates pre-configured resources, and the terminal autonomously activates and deactivates the pre-configured resources. See [link / reference]. Figure 9

[0318] The configuration information of the pre-configured resources sent by the base station includes the pre-configured resource period, time slot occupation and frequency domain resource occupation, transmission format, time start of the pre-configured resources, the initial state of the pre-configured resources being deactivated, and multiple pre-configured resources in one pre-configured resource period.

[0319] It should be noted that the difference in Embodiment 2 is that after the terminal sends the activation resource instruction, the pre-configured resource is activated from the next pre-configured resource (instead of the next pre-configured resource cycle), even if this pre-configured resource is located after the start of the pre-configured resource cycle.

[0320] After the terminal sends the deactivation resource instruction, it begins deactivating the pre-configured resource from the next pre-configured resource (not the next pre-configured resource cycle), even if the pre-configured resource is located after the start of the pre-configured resource cycle. The other processes are the same as in Example 1.

[0321] In Example 2, the initial state of the pre-configured resource is deactivated. If the base station configuration information indicates that the initial state of the pre-configured resource is activated, the terminal can directly use the pre-configured resource. Afterwards, a deactivation instruction for the pre-configured resource can be sent to deactivate the pre-configured resource.

[0322] Example 3: The base station allocates pre-configured resources, the terminal autonomously activates the pre-configured resources, and the base station deactivates the pre-configured resources. See [link to example]. Figure 10

[0323] The configuration information of the pre-configured resources sent by the base station includes the pre-configured resource period, time slot occupation and frequency domain resource occupation, transmission format, time start of the pre-configured resources, the initial state of the pre-configured resources being deactivated, and multiple pre-configured resources in one pre-configured resource period.

[0324] It should be noted that Embodiment 3 corresponds to Embodiment 1. The difference between Embodiment 3 and Embodiment 1 is that the deactivation of pre-configured resources is controlled by the base station. The deactivation resource indication sent by the base station can be carried by the DCI of the PDCCH or by the MAC CE.

[0325] Here, if the initial state of the pre-configured resources is active, since the deactivation of the pre-configured resources in this embodiment is controlled by the base station, the base station can only send the deactivation resource instruction, and the terminal cannot activate it independently.

[0326] Example 4: The base station allocates pre-configured resources, the terminal autonomously activates the pre-configured resources, and the base station deactivates the pre-configured resources. See [link to example]. Figure 11

[0327] The configuration information of the pre-configured resources sent by the base station includes the pre-configured resource period, time slot occupation and frequency domain resource occupation, transmission format, time start of the pre-configured resources, the initial state of the pre-configured resources being deactivated, and multiple pre-configured resources in one pre-configured resource period.

[0328] It should be noted that Example 4 corresponds to Example 2. The difference between Example 4 and Example 2 is that the deactivation of pre-configured resources is controlled by the base station. The deactivation resource indication sent by the base station can be carried by the DCI of PDCCH or by MAC CE.

[0329] Here, if the initial state of the pre-configured resources is active, since the deactivation of the pre-configured resources in this embodiment is controlled by the base station, the base station can only send the deactivation resource instruction, and the terminal cannot activate it independently.

[0330] Example 5: The base station allocates pre-configured resources, and the terminal autonomously activates and deactivates the pre-configured resources. See [link / reference] Figure 12

[0331] It should be noted that Example 5 corresponds to Example 1, except that the terminal directly uses a pre-configured resource and activates it before accessing the pre-configured resource; after the base station detects that the terminal has used the pre-configured resource, it considers the pre-configured resource to be activated.

[0332] In this embodiment, after the resources are pre-configured, the terminal sends an explicit deactivation instruction to deactivate the pre-configured resources.

[0333] Of course, pre-configured resources can also be activated using one of the following methods:

[0334] The base station sends a deactivation resource indication to deactivate the pre-configured resource;

[0335] When a terminal stops using pre-configured resources, the base station starts a timer. This timer starts when the pre-configured resources do not include data from the terminal. If no data is received from the terminal within the timeout period, the pre-configured resources are considered deactivated.

[0336] Example 6: The base station allocates pre-configured resources, and the terminal autonomously activates and deactivates the pre-configured resources. See [link to example]. Figure 13

[0337] The configuration information of the pre-configured resources sent by the base station includes the pre-configured resource period, time slot occupancy and frequency domain resource occupancy, transmission format, the initial state of the pre-configured resources being deactivated, and multiple pre-configured resources in one pre-configured resource period.

[0338] It should be noted that Example 6 corresponds to Example 1, and the difference between Example 6 and Example 1 is:

[0339] 1) The RRC signaling of the base station to allocate pre-configured resources does not determine the actual start point of the pre-configured resource cycle. After the terminal sends the activation resource indication, the pre-configured resources are activated at the corresponding time point after a determined time interval.

[0340] Here, the corresponding time interval is the time point obtained by adding the time interval to the moment when the activation resource indication is sent.

[0341] It should be noted that this specific time interval can be included in the configuration information, in the resource activation instruction, or as specified by the protocol.

[0342] 2) If an activated pre-configured resource is deactivated, when the terminal reactivates the pre-configured resource, the interval between the starting position of the newly activated pre-configured resource and the previously activated pre-configured resource may not be an integer multiple of the pre-configured resource period indicated by the base station.

[0343] In this embodiment, after the resources are pre-configured, the terminal sends an explicit deactivation instruction to deactivate the pre-configured resources.

[0344] Example 7: The base station allocates pre-configured resources, the terminal autonomously activates the pre-configured resources, and the base station deactivates the pre-configured resources. See [link to example]. Figure 14

[0345] The configuration information of the pre-configured resources sent by the base station includes the pre-configured resource period, time slot occupation and frequency domain resource occupation, transmission format, time start of the pre-configured resources, the initial state of the pre-configured resources being deactivated, and multiple pre-configured resources in one pre-configured resource period.

[0346] It should be noted that Example 7 corresponds to Example 1. The difference between Example 7 and Example 1 is that both the base station and the terminal activate the pre-configured resources autonomously on CC1 corresponding to the activated RLC entity according to the PDCP retransmission activation instruction sent by the base station.

[0347] In this embodiment, after activating the pre-configured resources, the RLC entity corresponding to CC1 participating in the PDCP repeated transmission is deactivated by the PDCP repeated transmission deactivation command sent by the base station.

[0348] Of course, pre-configured resources can also be activated using one of the following methods:

[0349] The terminal sends an explicit deactivation resource instruction, thereby deactivating the pre-configured resource;

[0350] The base station sends a deactivation resource indication to deactivate the pre-configured resource.

[0376] Optionally, the processor is configured to read program instructions from the memory and perform the following operations:
