Description

Resource allocation method and device and terminal device

The present application claims priority to Chinese Patent Application, filed on March 16, 2017, to the Chinese Patent Office, the number of which is hereby incorporated by reference. In this application.

Technical field

The embodiments of the present invention relate to communication technologies, and in particular, to a resource allocation method and apparatus, and a terminal device.

Background technique

With the rapid development of terminal equipment requirements and technology, the 5th Generation mobile communication technology (5G) system or the new radio access technology (New radio, NR) is coming soon, and the 5G system or NR system can provide the ratio. The Long Term Evolution (LTE) network has a faster transmission rate, and its highest theoretical transmission rate can reach tens of gigabytes per second (Gigabyte, Gb for short).

User Equipment (UE) has three basic modes of operation in the Long-Term Evolution (LTE) system: DETACHED, IDLE, and ACTIVE.

LTE-DETACHED: When the UE is powered on, the UE first enters the LTE-DETACHED state. At this time, the UE does not register with the network, and may fail to register because there is no registration or no suitable network.

LTE-IDLE (idle state): The UE is registered to the network but is not activated. The user equipment is in the standby state. There is no state when the service exists. After the UE is powered on, it stays in the idle mode and is in the low power mode. The domain has already learned the location of the UE. If there is service establishment, the UE can switch to the ACTIVE mode in a very short time and continue the previously activated data session. In the LTE-IDLE state, the network side can know exactly the tracking area where the UE is located. When the UE is called, the network can page within the latest tracking area of the user equipment. In the IDLE state, the UE has no context, and the UE is not connected to the base station (eNodeB) and the core network (CN).

LTE-ACTIVE (active state): refers to the state when the radio resource control (RRC) connection is established between the user equipment and the radio network controller (RNC). At this time, the user equipment has Stationed in a cell, the UE is in a state of receiving and transmitting data, which is the only active state in which the UE and the network actually exchange data and signaling. When the UE in the LTE-ACTIVE state moves between two LTE cells, a handover will occur, and the eNodeB can determine the mechanism of handover, thereby reducing the delay of data transmission interruption. In the ACTIVE state, the eNodeB stores the Access Stratum (AS) context of the UE, and the Cell Radio Network Temming Identity (C-RNTI) of the UE. The eNodeB and the CN are dedicated. connection.

There is also a concept of a light connection state in LTE. A state called Inactive State (INACTIVE) is also introduced in the Radio Access Technology (RAT) of the 5G system, and the INACTIVE state and LTE are light. The connection state is similar, except that the UE is connected between the CN and the access network.

As shown in FIG. 1 , it is a schematic diagram of a network structure of a 5G system in the prior art, where the 5G system generally includes a new core network (NG-core, NGC) and at least one new radio access technology base station (gNB), at 5G. In the INACTIVE state of the system, the gNB has a dedicated connection with the NGC. The gNB stores the context of the UE, and also stores the identifier of the UE context (Resume ID or Context ID) of an area (called a notification area or a paging area). The Resume ID is unique in the area, and the Resume ID generally includes a base station identifier (gNB ID) and a user equipment identifier (UE ID), and the area corresponding to the Resume ID may include multiple cells.

Corresponding to the UE in the light connection/INACITVE state, the interface between the CN and the Radio Access Network (RAN) is anchored to one RAN node (for example, the second base station), and then the cell reselection mobility can be performed. The UE does not need to notify the base station when moving within the area of one Resume ID, and once the UE leaves the area, the UE needs to inform the base station of its location. This process is called location area update.

When the UE is to be restored from the INACITVE state to the ACTIVE state, a radio resource control (RRC) connection recovery process needs to be initiated. As shown in FIG. 2, it is a schematic diagram of a process of RRC connection recovery in the prior art.

The UE randomly selects a signature ID (Signature ID), and sends a Preamble (Message1) corresponding to the signature ID. When the gNB receives the preamble signal, the physical layer processes the signal through correlation, and accurately acquires the uplink time advance. The amount and the uplink transmit power, read the preamble of the UE, and report it to the MAC. The MAC of the gNB allocates a C-RNTI, selects a response channel of the preamble, and transmits the C-RNTI to the physical layer. The physical layer transmits C-RNTI, time and power information (Message 2) to the UE on the response channel of the preamble corresponding to the signature ID. When two or more UEs simultaneously transmit preamble signals through different signature IDs, the gNB can distinguish preambles of different UEs and provide different C-RNTIs and other information to different UEs on different preamble response channels. .

The UE initiates an RRC connection recovery procedure in the message 3. The UE sends a connection recovery request (RRC Conn. Resume Request) to the gNB, and the gNB allocates a dedicated transmission scheduling request (Scheduling Reqeust, SR) resource and channel quality indication (Channel). The quality indicator (CQI) reports the resource, the channel state information (CSI), the resource, the sounding reference signal (SRS), and other bearer configuration parameters; the UE receives the connection recovery response message sent by the gNB ( RRC Conn.Resume Response), the connection recovery response message includes the UE-specific SR transmission resource, CQI reporting resource, CSI reporting resource, SRS transmission resource, and other bearer configuration parameters, and the UE then sends an RRC connection recovery complete message (RRC Conn) .Resume Complete), then the UE enters the ACTIVE state for data transmission, and releases the RRC link resource after the data transmission is completed.

However, in the current 5G, when the gNB is composed of a centralized unit (CU) and a distributed unit (DU), the CU is generally responsible for centralized radio resources and connection management control, and the DU generally includes implementing distributed users. Surface processing function. The resources allocated by the CU are first transmitted to the DU and then transmitted to the UE by the DU. Therefore, the interface between the CU and the DU may be an undesired transmission link, and the connection process is extended by the transmission of the DU and the CU, so the AC connection is entered. The delay is longer and the delay in sending data is also compared. Moreover, after the UE is in the ACTIVE state and the physical uplink control channel (PUCCH) dedicated resource has been released, the UE needs to initiate a random access procedure. After the access succeeds, the DU needs to wait for the CU to allocate through the RRC message. Dedicated resources.

Therefore, since the transmission between the DU and the CU takes time, it is easy to cause more delay for the UE to access.

At the same time, the same problem exists in the distributed base station system, where the distributed base station includes a first base station (also referred to as a serving base station) and a second base station (also referred to as an anchor base station), and the terminal device communicates with the first base station through an air interface. The first base station communicates with the second base station by wire or wirelessly, and the second base station manages various resources and contexts of the respective terminal devices.

For the random access process, in the prior art, the base station also needs to wait for the integrity check of the terminal device to allocate resources to the terminal device, and thus, it also causes more delay.

Optionally, the first base station/distributed unit may allocate the dedicated uplink resource to the terminal device from the uplink resource it manages before and after receiving the uplink information sent by the terminal device, and send the dedicated uplink resource to the terminal device. For example, the first base station/distributed unit does not receive the first base station/distributed unit if the timer maintained by the first base station/distributed unit expires before receiving the uplink information of the terminal device. When the terminal device uses the information sent by the resource, it is determined that the terminal device does not have the corresponding resource or releases the corresponding resource, and actively allocates the dedicated uplink resource to the terminal device and sends the dedicated uplink resource to the terminal device.

Step 302: The first base station or the distributed unit receives information that is sent by the terminal device by using the received dedicated uplink resource.

The “dedicated” refers to only the terminal device, that is, the dedicated uplink resource is only allocated to the terminal device for use. In another embodiment of the present invention, resources allocated by a plurality of terminal devices are the same over a period of time.

Optionally, the first base station or the distributed unit passes physical layer control signaling or a Media Access Control (MAC) Control Unit (MAC CE) or a Packet Data Convergence Protocol (PDCP). And the control unit sends the allocated dedicated uplink resource to the terminal device.

If the second base station/centralized unit does not generate a check success indication, the first base station/distributed unit fails to receive a check success indication when the timer expires, and the default check succeeds. The timer can be started when the first base station/distributed unit transmits verification information to the second base station/centralized unit.

Optionally, when the second base station/centralized unit check succeeds, the first base station/distributed unit may send the verification success indication to the terminal device, or may not send the verification success. Indicated to the terminal device.

Optionally, if the first base station/distributed unit does not receive the verification success indication generated by the second base station/centralized unit and generates a dedicated resource release indication to notify the terminal device within a predetermined time.

Optionally, the first base station/distributed unit receives a verification result of performing integrity check on the terminal device by the second base station/centralized unit; the first base station/distributed unit according to the The verification result determines whether a dedicated resource release indication is generated and transmitted to notify the terminal device. For example, if the verification fails, the first base station/distributed unit generates and sends a dedicated resource release indication to the terminal device according to the verification failure indication sent by the second base station/centralized unit; if the verification is successful, The first base station/distributed unit may send a verification success indication sent by the second base station/centralized unit to the terminal device, and the first base station/distributed unit may not send the first The verification success indication of the second base station/centralized unit is sent to the terminal device. If the first base station/distributed unit does not send the verification success indication of the second base station/centralized unit to the terminal device, if the terminal device does not receive the dedicated resource release indication when the timer expires The default verification is successful. The timer may be started when the terminal device sends verification information to the first base station/distributed unit.

In another embodiment of the present invention, if the terminal device does not receive the verification success indication within a predetermined time, the default verification fails, and then the dedicated uplink resource is released.

The first base station/distributed unit reports the resource usage of at least one of the following: an SR transmission resource, a CQI reporting resource, a CSI reporting resource, an SRS reporting resource, a PUSCH resource, and a terminal device identifier used by the single cell for scheduling. For example, the first base station/distributed unit reports whether at least one resource of the foregoing various resources is used up, or reports a residual value or a used value of at least one resource of the foregoing various resources, and the like.

In another embodiment of the present invention, if the first base station/distributed unit periodically reports resource usage information to the second base station/centralized unit, the first base station/distributed unit further The second base station/centralized unit transmits period related parameters, such as cycle time. The period related parameters may be carried in the resource usage information. Among them, this step is optional.

Step 702: The second base station/centralized unit allocates resources to the first base station or the distributed unit.

For example, if the terminal device switches to another cell or the terminal device leaves the connected state, for example, the terminal device enters the INACTIVE state or the IDLE state, the terminal device notifies the information about the switching or leaving the connected state. a second base station/centralized unit, the second base station/centralized unit notifying the first base station/distributed unit of the following information according to the information of the handover or leaving the connection state of the terminal device: the terminal device leaves the connection state Or the terminal device has released the resource, or the resource allocated for the terminal device becomes available, and the first base station/distributed unit re-manages the released resource or available resource for allocation to other terminal device or Secondary allocation. In another embodiment of the invention, the second base station/centralized unit periodically allocates resources to the first base station or the distributed unit.

The second base station/centralized unit may further update the resources that can be allocated to the terminal device according to the resource usage information reported by the first base station/distributed unit to the first base station or the distributed unit.

For example, the first base station/distributed unit reports that at least one resource of the foregoing various resources has been used, and the second base station/centralized unit allocates the used resource to the first base station/distributed again. unit.

For example, the first base station/distributed unit reports a residual value or a used value of at least one resource of the foregoing various resources, if the second base station/centralized unit determines whether the remaining value of the resource is less than or equal to the first threshold. And if the remaining value is less than or equal to the first threshold, the second base station/centralized unit allocates the resource to the first base station/distributed unit again, and if the remaining value is greater than the first threshold, the second base station/ The centralized unit does not allocate the resource to the first base station/distributed unit; for example, if the second base station/centralized unit determines whether the usage value of the resource is greater than or equal to a second threshold, if the usage value is greater than or Equal to the second threshold, the second base station/centralized unit allocates the resource to the first base station/distributed unit again, and if the used value is less than the second threshold, the second base station/centralized unit is not allocated. The resource is given to the first base station/distributed unit.

For example, the second base station/centralized unit allocates at least one of the following resources: an SR transmission resource, a CQI reporting resource, a CSI reporting resource, an SRS reporting resource, a PUSCH resource, and a terminal device identifier used by the single cell for scheduling.

Step 703: The first base station/distributed unit receives the resource allocated by the second base station/centralized unit.

FIG. 8 is a schematic flowchart of a resource allocation method according to another embodiment of the present invention. In this embodiment, a terminal device in an INACTIVE state in a single cell or paging area, where the base station is the first base station or gNB is example.

The resource allocation method is performed by a first base station or a distributed unit of a gNB, and if the resource allocation method is performed by a distributed unit of a gNB, the gNB includes a distributed unit and a centralized unit, and the distributed unit and The centralized unit is connected by wire or wireless. In another embodiment of the present invention, if the resource allocation method is performed by the first base station, the first base station is connected to the second base station by wire or wireless, and therefore, the first base station and the distributed in this embodiment The unit has the same function, and the second base station has the same function as the centralized unit, that is, the present embodiment describes two communication scenarios: one is that the terminal device communicates with the first base station through the air interface, and then the first base station and the second base station The first base station acquires resources and manages the second base station, and the second base station manages a context of each terminal device, where the first base station may also be referred to as a serving base station, and the second base station may also It is called an anchor base station; the other is that the terminal device communicates with the distributed unit of the base station through the air interface, and then the distributed unit communicates with the centralized unit of the base station, and the distributed unit acquires resources from the centralized unit and manages the same. The centralized unit manages the context of each terminal device.

Optionally, the first base station or the second base station may be a base station (BTS) in a GSM system or a CDMA system, or a base station (NodeB) in WCDMA, and an evolved base station (eNodeB) in an LTE system. Or a base station (gNB) of a new radio access network.

The resource includes at least one of the following: an SR transmission resource, a CQI reporting resource, a CSI reporting resource, an SRS reporting resource, a PUSCH resource, and a terminal device identifier used by the single cell for scheduling.

The paging area refers to a terminal device in a range of a wireless network area, where the area may be a single cell or multiple cells, and the terminal device has a unique wireless network identifier (resume ID) or context identifier (context ID). The terminal device moves between cells in this paging area without notifying the network, such as a base station.

Step 801: The terminal device in the INACTIVE state sends uplink information to the first base station/distributed unit.

For example, the terminal device sends the uplink information to the first base station/distributed unit through a non-scheduled or random access (RACH) process, and the uplink information may include at least one of the following: preamble, terminal device_ID, and MAC-I. , Buffer State Report (BSR), signaling, or data packet.

Step 802: The first base station/distributed unit sends at least one of the following resources that are managed by the first base station/distributed unit: an SR sending resource, a CQI reporting resource, a CSI reporting resource, an SRS reporting resource, a PUSCH resource, and a single cell for scheduling Terminal device identification.

For example, at least one of the following resources managed by the first base station/distributed unit: the SR transmission resource, the CQI reporting resource, the CSI reporting resource, the SRS reporting resource, the PUSCH resource, and the terminal device identifier used by the single cell for scheduling The physical downlink control channel (PDCCH, Physical Downlink Control Channel) or the MAC control unit is sent to the terminal device.

For example, in the RACH process, the uplink information is a random access request, and the first base station/distributed unit will send any RAR random access response (ie, MSG2) or MSG4 or any time period between MSG2 and MSG4. The allocated resources are sent to the terminal device. For example, the first base station/distributed unit transmits the allocated resources to the terminal device through MSG2 (eg, sending grant) or MSG4 (eg, transmitting CR). In another embodiment of the present invention, the first base station/distributed unit may transmit the allocated resources to the terminal during a time period between transmitting MSG2 (eg, transmitting grant) and MSG4 (eg, transmitting CR). device.

For example, in the non-scheduled transmission process, when the first base station/distributed unit receives the uplink data sent by the terminal device, the first base station/distributed unit sends the allocated resource to the terminal device when the collision resolution response is not scheduled.

For example, the terminal device may report the capability of supporting the first base station/distributed unit to allocate the resource, and the terminal device indicates to the first base station/distributed unit when transmitting uplink, such as by using a MAC control unit ( a control element) or a special preamble indication; in another embodiment of the present invention, the terminal device reports to the second base station/centralized unit that the first base station/distributed unit allocates the resource The capability, the second base station/centralized unit then indicates the capability to the first base station/distributed unit.

After the downlink service triggers, the second base station/centralized unit determines the cell where the terminal device is located, and the first base station/distributed unit passes physical layer control signaling (such as PDCCH) or high layer signaling (such as MAC CE). Or the PDCP control unit sends at least one of the allocated SR transmission resource, the CQI reporting resource, the CSI reporting resource, the SRS reporting resource, the PUSCH resource, and the terminal device identifier used by the single cell for scheduling to the terminal device. In this embodiment, step 801 is optional.

The allocated resources may include static parameters (eg, periods, etc.) required for the use of the resources for transmission. If not included, the terminal device uses default or pre-configured static parameters.

Step 803: After receiving the resource, the terminal device sends an acknowledgement feedback indication to the first base station/distributed unit.

This step is optional and may or may not be performed. After receiving a resource or all resources, the terminal device sends an acknowledgement feedback indication to the first base station/distributed unit. If the terminal device receives multiple resources, the terminal may send the resource. A list is indicated to the first base station/distributed unit. For example, if the terminal device receives at least two of the SR transmission resource, the CQI reporting resource, the CSI reporting resource, the SRS reporting resource, the PUSCH resource, and the terminal device identifier used by the single cell for scheduling, sending the corresponding resource list indication to the First base station/distributed unit.

Step 804: The terminal device performs corresponding transmission by using corresponding resources allocated by the first base station/distributed unit according to requirements.

Optionally, if the terminal device in the INACTIVE state receives the allocated dedicated resource, and restores the previously saved ACTIVE configuration parameter, for example, carrying the relevant configuration information, the terminal device considers that the ACTIVE state is entered. The terminal device calculates a new key for security protection in the ACTIVE state.

For example, if the terminal device needs to send a scheduling request, the terminal device sends a scheduling request by using the SR transmission resource allocated by the first base station/distributed unit.

For example, if the terminal device needs to send a CQI, the terminal device sends the CQI by using the CQI reporting resource allocated by the first base station/distributed unit.

For example, if the terminal device needs to send CSI, the terminal device sends CSI by using the CSI reporting resource allocated by the first base station/distributed unit.

For example, if the terminal device needs to send the SRS, the terminal device sends the SRS by using the SRS reporting resource allocated by the first base station/distributed unit.

For example, if the terminal device needs to transmit data (Data), the terminal device transmits Data by using the PUSCH resource allocated by the first base station/distributed unit.

For example, if the terminal device needs to send uplink data or signaling on the shared resource, the terminal device uses the single cell allocated by the first base station/distributed unit for scheduling terminal device identification and data/signaling together. send.

Step 805: The first base station/distributed unit sends an indication that the dedicated resource has been allocated to the terminal device to the second base station/centralized unit.

For example, if the first base station/distributed unit detects that the terminal device transmits the allocated resource, or receives a feedback indication of the configuration acknowledgement sent by the terminal device, the first base station/distributed unit notifies the first The second base station/centralized unit has assigned an indication of the dedicated resource to the terminal device, for example, an index of the allocated resource or the content of the resource may be transmitted.

For example, if the first base station/distributed unit detects that the terminal device transmits the SR in the allocated SR transmission resource, or reports the resource transmission CQI on the allocated CQI, or reports the resource transmission CSI in the allocated CSI, or the allocated SRS. The reporting resource sends the SRS, or the data is transmitted in the allocated PUSCH resource, or the single cell is used to send the terminal device identifier, or the first base station/distributed unit receives the configuration confirmation that the terminal device sends the configuration. When the feedback indication is received, the first base station/distributed unit notifies the second base station/centralized unit that an indication of the corresponding dedicated resource has been allocated to the terminal device, for example, including an index of the corresponding resource.

Optionally, the first base station/distributed unit may further notify the second base station/centralized unit by entering the terminal device into an active indication. This embodiment does not exclude the use of this method instead of the 8.5 step, implicitly indicating that the terminal device is allocated a dedicated resource. The following steps 806 to 809 are optional.

Steps 806-807, the terminal device sends the MAC-I to the second base station/centralized unit through the first base station/distributed unit for integrity check.

If the first base station/distributed unit receives the MAC-I sent by the terminal device, the first base station/distributed unit forwards the MAC-I to the second base station/concentrated unit, the second base station / Centralized unit for integrity checking.

Step 808: The second base station/centralized unit sends a dedicated resource release indication or a check result indication that fails verification to the first base station/distributed unit.

Step 809: The first base station/distributed unit sends a dedicated resource release indication or a check result indication to the terminal device.

For example, the second base station/centralized unit determines whether to generate and send the dedicated resource release indication according to the check result, and if the check fails, the second base station/centralized unit generates a dedicated resource release indication and sends the indication to the local base station. The first base station/distributed unit is then sent to the terminal device to notify the terminal device to release the corresponding dedicated resource. If the verification is successful, the second base station/centralized unit may generate and send a verification success indication to the first base station/distributed unit, and the second base station/centralized unit may also not generate a verification success. Instructions. If the second base station/centralized unit does not generate a check success indication, if the first base station/distributed unit does not receive the check success indication when the timer expires, the default check succeeds. The timer can be started when the first base station/distributed unit transmits verification information to the second base station/centralized unit.

In another embodiment of the present invention, the second base station/centralized unit sends a verification success result to the first base station/distributed unit, and the first base station/distributed unit performs verification according to the first base station/distributed unit. Whether the success result determines whether a dedicated resource release indication is generated, for example, if the verification fails, the first base station/distributed unit generates a dedicated resource release indication and sends the dedicated resource release indication to the terminal device, and notifies the terminal device to release the corresponding dedicated resource. If the verification is successful, the first base station/distributed unit may send a verification success indication sent by the second base station/central unit to the terminal device, and the first base station/distributed unit also The verification success indication of the second base station/centralized unit may not be sent to the terminal device. If the first base station/distributed unit does not send the verification success indication of the second base station/centralized unit to the terminal device, if the terminal device does not receive the dedicated resource release indication when the timer expires The default verification is successful. The timer may be started when the terminal device sends verification information to the first base station/distributed unit.

If the verification fails, the first base station/distributed unit notifies the terminal device to perform an RRC connection release or an RRC suspension, reconfiguration, update key, and the like.

In another embodiment of the invention, steps 806-809 may be performed prior to step 804, ie, an integrity check is performed before the terminal device performs a corresponding transmission according to the assigned respective resource.

In another embodiment of the present invention, if the terminal device is within a paging area, the second base station/second base station/central unit respectively configures multiple sets of common to the first base station/first base station/distributed unit network. The combined resources (for example, at least two of an SR transmission resource, a CQI reporting resource, a CSI reporting resource, an SRS reporting resource, a PUSCH resource, and a single cell for scheduling a terminal device identification resource), and corresponding periods, Broadcast or agreement. The first base station or the first base station/distributed unit allocates a resource combination index value to the terminal device. The resource combination index value indicates information of at least two resources, and the terminal device uses the resource combination index value to acquire a corresponding resource from a protocol agreement or a pre-configured resource.

Optionally, the same resource can be allocated to multiple terminal devices.

In this embodiment, after receiving the uplink information of the terminal device, the first base station/distributed unit of the base station does not have to wait for the second base station/centralized unit to perform integrity check on the terminal device, and then The second base station/centralized unit acquires the resource and sends the resource to the terminal device, but the first base station/distributed unit does not wait for the integrity check result to autonomously allocate the managed resource to the terminal device in advance, saving the first The time at which a base station/distributed unit waits for an integrity check and the time at which resources are acquired from the second base station/centralized unit.

FIG. 9 is a schematic flowchart of a resource allocation method according to another embodiment of the present invention. In this embodiment, a terminal device communicates with a base station through an air interface, and the base station manages a resource and a context of each terminal device.

If the terminal device moves between cells in this paging area, there is no need to notify the network, such as a base station.

In another embodiment of the present invention, the terminal device may also be in a connected state or an idle state.

In step 901, the terminal device sends uplink information to the base station.

For example, the uplink information that the terminal device sends the uplink information to the base station by using a non-scheduled or random access (RACH) process may include at least one of the following: preamble, terminal device_ID, MAC-I, and buffer status report (Buffer). State Report, BSR), signaling or data packet.

For example, the base station allocates and transmits to the terminal device at least one of the following resources: the SR transmission resource, the CQI reporting resource, the CSI reporting resource, the SRS reporting resource, the PUSCH resource, and the terminal device identifier used by the single cell for scheduling.

The base station uses the physical layer control signaling or the MAC CE or the PDCP control unit to at least one of the SR transmission resource, the CQI reporting resource, the CSI reporting resource, the SRS reporting resource, the PUSCH resource, and the terminal device identifier used by the single cell for scheduling. Transmitted to the terminal device.

For example, in the RACH process, the uplink information is a random access request, and the uplink information is a random access request, and the base station sends an RAR random access response (ie, MSG2) or MSG4 or between MSG2 and MSG4. The allocated resources are transmitted to the terminal device at any time period. For example, the base station transmits the allocated resources to the terminal device through MSG2 (eg, sending grant) or MSG4 (eg, transmitting CR).

For example, in the non-scheduled transmission process, when receiving the uplink data sent by the terminal device, the base station sends the allocated resource to the terminal device when the collision resolution response is not scheduled.

Optionally, in order to support data transmission in a fast manner, in a scenario where the CU and the DU are separated, the CU configures parameters of the relevant bearer on the DU. For example, the parameters of the related bearer include at least one of the following: a logical channel, a mode of the RLC. , SN size, window size, reordering timer, etc. For example, the terminal device may report the capability of supporting the base station to allocate the resource, and the terminal device indicates to the base station when transmitting uplink, such as by a MAC control unit or a special preamble.

After the downlink service triggers, the base station determines the cell where the terminal device is located, and the base station sends the allocated SR resource, CQI, through physical layer control signaling (such as PDCCH) or high layer signaling (such as MAC CE) or PDCP control unit. At least one of the reporting resource, the CSI reporting resource, the SRS reporting resource, the PUSCH resource, and the terminal device identifier used by the single cell for scheduling is sent to the terminal device.

Step 903: After receiving the resource, the terminal device sends an acknowledgement feedback indication to the base station.

This step is optional and may or may not be performed. After receiving a resource or all resources, the terminal device sends an acknowledgement feedback indication to the base station. If the terminal device receives multiple resources, the terminal may send a resource list indication to the base station. . For example, if the terminal device receives at least two of the SR transmission resource, the CQI reporting resource, the CSI reporting resource, the SRS reporting resource, the PUSCH resource, and the terminal device identifier used by the single cell for scheduling, sending the corresponding resource list indication to the Base station.

Step 904: The terminal device performs corresponding transmission according to the corresponding resource allocated by the base station as needed.

Optionally, if the terminal device in the INACTIVE state receives the allocated dedicated resource, and restores the previously saved ACTIVE configuration parameter, for example, carrying the relevant configuration information, the terminal device considers that the terminal enters the ACTIVE state, and the terminal device calculates the new key. Used for security protection in the ACTIVE state.

For example, if the terminal device needs to send a scheduling request, the terminal device sends a scheduling request by using the SR transmission resource allocated by the base station.

For example, if the terminal device needs to send the CQI, the terminal device sends the CQI by using the CQI reporting resource allocated by the base station.

For example, if the terminal device needs to send CSI, the terminal device transmits CSI by using the CSI reporting resource allocated by the base station.

For example, if the terminal device needs to send the SRS, the terminal device sends the SRS by using the SRS reporting resource allocated by the base station.

For example, if the terminal device needs to transmit data (Data), the terminal device transmits Data by using the PUSCH resource allocated by the base station.

For example, if the terminal device needs to send uplink data or signaling on the shared resource, the terminal device uses the single cell allocated by the base station to send the terminal device identifier and the data/signaling together.

Step 905: The terminal device sends the MAC-I to the base station for integrity check.

Step 906: The base station sends, to the terminal device, a dedicated resource release indication or a verification success indication that fails to be verified.

For example, the base station determines whether to generate and send the dedicated resource release indication according to the check result. If the check fails, the base station generates a dedicated resource release indication and sends the dedicated resource release indication to the terminal device, and notifies the terminal device to release the corresponding Dedicated resources. If the verification is successful, the base station may generate and send a verification success indication to the terminal device, and the base station may not generate a verification success indication.

Optionally, the base station sends the dedicated resource release indication to the terminal device by using physical layer control signaling or a MAC CE or a PDCP control unit.

If the base station does not generate a check success indication, if the terminal device does not receive the check success indication when the timer expires, the default check succeeds. The timer can be started when the terminal device sends the verification information to the second base station/centralized unit.

If the verification fails, the base station notifies the terminal device to perform an operation such as RRC connection release or RRC suspension, reconfiguration, and update of a key.

The allocated resources are transmitted to the terminal device at any time period with the MSG 4. For example, the transmitter 1003 is configured to send the allocated resources to the terminal device through MSG2 (eg, sending grant) or MSG4 (eg, transmitting CR).

For example, in the non-scheduled transmission process, when the receiver 1001 receives the uplink data sent by the terminal device, the transmitter 1003 is configured to send the allocated resource to the terminal device when the conflict resolution response is not scheduled.

For example, the terminal device may report the capability of supporting the base station to allocate the resource, and the terminal device indicates to the receiver 1001 when transmitting uplink, such as by a MAC control unit or a special preamble indication.

After the downlink service is triggered, the processor 1002 determines, after the terminal device is located, the transmitter 1003 is configured to allocate the physical layer control signaling (such as PDCCH) or higher layer signaling (such as MAC CE) or the PDCP control unit.

The receiver 1001 is further configured to receive verification information sent by the terminal device.

For example, the receiver 1001 is further configured to receive a MAC-I sent by the terminal device, and the processor 1002 is further configured to perform an integrity check according to the MAC-I.

The transmitter 1003 is further configured to send, to the terminal device, a dedicated resource release indication or a verification success indication generated by the processor 1002 check failure.

For example, the processor 1002 determines whether to generate the dedicated resource release indication or the verification success indication according to the check result. If the check fails, the processor 1002 generates a dedicated resource release indication and sends the identifier to the transmitter 1003. The terminal device notifies the terminal device to release a corresponding dedicated resource. If the verification is successful, the processor 1002 may generate a verification success indication and send the verification success indication to the terminal device through the transmitter 1003, and the processor 1002 may not generate a verification success indication. .

If the processor 1002 does not generate a verification success indication, if the terminal device does not receive the verification success indication when the timer expires, the default verification is successful. The timer can be started when the terminal device sends the verification information to the second base station/centralized unit.
