Description

Control method, control equipment and storage medium

Technical Field

The present disclosure relates to mobile communication technologies, and in particular, to a control method, apparatus, and storage medium.

Background

In the fifth generation (5th generation,5G) New Radio (NR) system, radio resource control (Radio Resource Control, RRC) states are divided into 3 types, which are respectively: an RRC IDLE state (rrc_idle), an RRC INACTIVE state (rrc_inactive), an RRC CONNECTED state (rrc_connected). Wherein the rrc_inactive state is a new state introduced by the 5G system from the energy saving point of view, for a terminal device (UE) in the rrc_inactive state, radio bearers and all radio resources are released, but the UE side and the base station side reserve the UE access context in order to quickly restore the RRC connection, and the network typically keeps the UE in the rrc_inactive state where data transmission is not frequent. Before Release-16, rel-16, the UE in rrc_inactive does not support data transmission, and when data arrives at the originating (MO) or receiving (Mobile Terminated, MT), the UE needs to restore the connection, and releases to rrc_inactive state after the data transmission is completed. For UEs with small data size and low transmission frequency, such a transmission mechanism may cause unnecessary power consumption and signaling overhead. Thus, rel-17 stands for research on small data transfer (Small Data Transmission, SDT) under rrc_inactive, project goals have two main directions: the uplink small data transmission based on the random access process (two steps/four steps) and the uplink small data transmission based on the pre-configured resource are not limited specifically.

CG

There are two modes of uplink scheduling of the terminal device, one is dynamic scheduling, namely Dynamic Grant (DG), and the other is CG. DG typically performs resource allocation by means of downlink control signaling (Downlink Control Information, DCI). CG includes two types, configuration grant Type 1 (configured grant Type, CG Type 1) and configuration grant Type 2 (configured grant Type, CG Type 2), respectively. Parameters such as time-frequency resource position, CG resource period, hybrid automatic repeat request (Hybrid Automatic Repeat Request, HARQ) process number using CG resource, modulation and coding strategy (Modulation and Coding Scheme, MCS) and the like of the configuration authorization type 1 are provided to the terminal equipment by the network equipment through RRC signaling, and are stored as configuration uplink authorization (configured uplink grant) by the terminal, and the terminal can use the configuration authorization for uplink data transmission after the RRC signaling configures the configuration authorization type 1; the period of configuring CG resources of grant type 2, the number of HARQ processes using CG resources, which MCS table to use, etc. parameters are provided to the terminal device by the network device through RRC signaling, but the time-frequency resource location, MCS index value, etc. are provided to the terminal by the network device through DCI and stored by the terminal as configuring uplink grants, i.e. configuring grant type 2 is activated or deactivated by physical layer or layer 1 signaling control.

Early data transmission (Early Data Transmission, EDT)

In LTE, EDT, i.e. small data transmission, has been introduced, during which the UE may remain in an idle (idle) state or a suspended (suspended) state or an inactive (inactive) state all the time, completing the transmission of uplink and/or downlink small data packets.

For the EDT process, the UE does not enter the connected state, and the transmission of the small packet is completed. In configuration, the network configures a maximum Transport Block (TB) size (size) allowed to be transmitted by the current network on a system information Block (System Information Block, SIB) 2, and the UE determines the amount of data to be transmitted, and if the amount of data to be transmitted is less than the maximum TB size, the UE may initiate EDT transmission; otherwise, the UE enters a connection state to transmit data using a normal connection establishment procedure.

If the cell in which the UE initiates Uplink (UP) -EDT is the same as the last serving cell, after receiving the connection recovery request and the Uplink data sent by the UE, the base station may directly submit the Uplink data to the core network, where the data transmission flow of the Uplink EDT is shown in fig. 2, and includes:

s201, the UE sends a random access preamble (Random Access Preamble) to the eNB;

S202, the eNB transmits a random access response to the UE (Random Access Response).

S203, the UE transmits an RRC connection resume request to the eNB (RRC Connretion resume request).

RRC Connretion resume request carries a resume identification (resume ID), a resume case (resume case), an authentication token (shortresumeMAC-I), and Uplink Data (Uplink Data).

S204, the eNB sends a UE text recovery request to the MME (Context resume request).

S205, the bearer is modified between the MME and the S-GW.

S206, the MME sends a text recovery response to the UE (Context resume response).

S207, the UE transmits uplink data to the S-GW.

S208, the S-GW sends downlink data to the base station.

Wherein S207 is optional.

S209, the eNB and MME perform a suspension procedure, and the MME and S-GW modify the bearer therebetween.

S210, the eNB transmits an RRC connection release notification to the UE (RRC Connction Release).

RRC Connction Release carries Release case (Release case), resume ID, NCC and downstream data.

Preconfigured uplink resources (Preconfigured Uplink Resource, PUR)

In LTE Release16, a method for transmitting data by PUR in idle state is introduced for a mobile internet of things scenario of narrowband internet of things (Narrow-Band Internet of Things, NB-IoT) and LTE-based global internet of things (eMTC). The PUR is only valid in the currently configured cell, i.e. when the UE detects a cell change and initiates a random access in the new cell, the UE needs to release the PUR of the original cell configuration. The PUR transmission flow is similar to the LTE UP-EDT shown in fig. 2, except that the process of transmitting a preamble acquisition Time Advance (TA) and an uplink scheduling grant (UL grant) is omitted.

The air interface flow based on PUR transmission is as shown in fig. 3, and before S203 of the air interface flow shown in fig. 2, the method comprises the following steps:

s200, the UE has effective PUR resources.

R17SDT

In the 5G NR system, the RRC states include 3 types, respectively: rrc_idle, rrc_inactive, and rrc_connected. Wherein, the rrc_inactive state is a new state introduced by the 5G system from the energy saving point of view, and for the UE in the rrc_inactive state, radio bearers and all radio resources are released, but the UE side and the base station side reserve the UE access context in order to quickly restore the RRC connection. The network typically keeps UEs with infrequent data transmissions in rrc_inactive state. Before Rel-16, the UE in rrc_inactive state does not support data transmission, and when MO or MT data arrives, the UE needs to resume connection, and releases to INACTIVE state after data transmission is completed. For UEs with small data size and low transmission frequency, such a transmission mechanism may cause unnecessary power consumption and signaling overhead. Thus, rel-17 stands for research on SDT under RRC_INACTIVE, project goals have two main directions: uplink small data transmission based on random access procedure (two/four steps) and uplink small data transmission based on pre-configured resources (such as CG type 1).

For small data transmissions based on pre-configured resources, the 3gpp RAN2 working group goes through the discussion to conclude that:

1. for CG-SDT, subsequent (sbusquent) data transmissions can use CG resources or DG resources (e.g., dynamic grant of C-RNTI addressed to UE), the detailed information of C-RNTI can be the same as the previous C-RNTI, or can be explicitly configured by the network, which can be discussed in stage 3.

2. The UE starts a window (window) for CG-SDT after CG/DG transmission. Further studies (For Further Study, FFS) were made on whether to design new timers or reuse existing timers.

3. CG-SDT dynamic authorization support retransmission

4. Uplink CG-SDT supports configuration of multiple HARQ processes.

It can be seen that the subsequent (sub-sequence) data transmission in the CG-SDT process may utilize either CG resources or DG resources, and may support configuration of multiple HARQ processes. In the CG-SDT process, the terminal starts a window after completing data transmission by using CG resources or DG resources each time, but the behavior of the terminal device in the window and after the window times out is not yet defined.

In order to facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies may be optionally combined with the technical solutions of the embodiments of the present application, which all belong to the protection scope of the embodiments of the present application. Embodiments of the present application include at least some of the following.

An optional process flow of the control method provided in the embodiment of the present application, as shown in fig. 4, includes the following steps:

s401, in the CG-SDT process, the terminal equipment completes first uplink data transmission by using a first CG resource or a first DG resource, and starts a first timer.

Optionally, the first CG resource or the HARQ process used by the first DG resource is a HARQ process configured for CG resources. In this embodiment of the present application, when CG resources are used to transmit first uplink data, CG resources for transmitting the first uplink data are referred to as first CG resources, and when DG resources are used to transmit first uplink data, DG resources for transmitting the first uplink data are referred to as first DG resources.

In this embodiment of the present application, the first uplink data is any uplink data sent by the terminal device to the network device by using CG resources or DG resources in the CG-SDT process, and the first uplink data sent by the terminal device to the network device by using the first CG resources or the first DG resources may be new transmission data or retransmission data.

Optionally, when the data last transmitted in the HARQ process for transmitting the first uplink data is not the first uplink data, the currently transmitted first uplink data is new transmission data, and the process for transmitting the first uplink data is new transmission.

Optionally, when the data last transmitted by the HARQ process for transmitting the first uplink data is the first uplink data, the currently transmitted first uplink data is retransmitted, and the process of transmitting the first uplink data is retransmitted.

In the embodiment of the present application, the first timer may be a new timer introduced, or may be a CG timer (CGT).

Optionally, the start timing of the first timer includes, but is not limited to, one of:

the method comprises the steps of A1, a first CG resource or a starting symbol of the first DG resource;

the time A2, the first CG resource or the last symbol of the first DG resource;

the opportunity A3 is a first PDCCH receiver opportunity after the first uplink data transmission is completed;

and the time A4 is after a period of time after the first uplink data transmission is completed.

And S402, during the operation of the first timer, the terminal equipment monitors the PDCCH scrambled by the first RNTI.

In this embodiment of the present application, the first RNTI is an RNTI configured for the CG-SDT process. Optionally, the first RNTI includes at least one of: one or more of a cell radio network temporary identity (Cell Radio Network Temporary Identifier, C-RNTI), a configured scheduling RNTI (Configured Scheduling RNTI, CS-RNTI), or other RNTIs configured for CG-SDT.

Alternatively, the length of the first timer may be dynamically configured by the network, or may be a predefined fixed length.

In this embodiment of the present application, the first timer is used for controlling the PDCCH, and the first timer may not be multiplexed or multiplexed in the newly transmitted control.

Scenes for control of first timer not multiplexed with new transmission

Taking the starting time of the first timer as a time A4, wherein the starting time of the first timer comprises one of the following steps:

the opportunity A41 is after the fixed duration of the first uplink data transmission is completed;

the timing a42 and the second timer time out.

When the starting time of the first timer is time A41, the terminal equipment monitors the time after the first uplink data is transmitted, and when the monitored time length reaches a fixed time length, the first timer is started.

As shown in fig. 5A, the terminal device completes transmission of the first uplink data 501 at time T1, and starts a first timer at time T2, where the interval between time T1 and time T2 is fixed by a period T.

Optionally, the fixed duration is predetermined or network device configured.

When the starting time of the first timer is time A42, the terminal equipment completes the transmission of the first uplink data, starts the second timer, and starts the first timer when the second timer is overtime.

As shown in fig. 5B, the terminal device completes the transmission of the first uplink data 501 at time t1, starts the second timer at time t3, and starts the first timer at time t4 when the second timer times out at time t 4.

In some embodiments, the start timing of the second timer includes one of:

the first CG resource or the first symbol position of the first DG resource at occasion B1;

the time B2, the first CG resource or the last symbol position of the first DG resource;

and the opportunity B3 is the receiving opportunity of the first PDCCH after the first uplink data transmission is completed.

In some embodiments, the configuration of the length of the second timer includes one of:

dynamically configuring network equipment;

a predefined fixed length.

In some embodiments, during operation of the second timer, the terminal device does not listen to the PDCCH scrambled by the first RNTI.

After the first uplink data is completed, the terminal equipment starts a second timer, does not monitor the PDCCH scrambled by the first RNTI during the operation of the second timer, starts the first timer after the second timer is overtime, and monitors the PDCCH scrambled by the first RNTI during the operation of the first timer.

As shown in fig. 5B, the PDCCH is not monitored between time t1 and time t4 when the second timer is running, and the PDCCH is monitored after the second timer is started.

After the terminal equipment finishes transmitting one uplink data transmission, the terminal equipment receives the uplink data from the transmission of the uplink data to the network equipment, decodes the uplink data, and feeds back the PDCCH to the terminal, so that the UE cannot receive the PDCCH transmitted by the network even if the UE keeps monitoring during the period of time, and therefore, the power consumption of the terminal equipment can be saved by controlling the PDCCH not to be monitored through the second timer, and the purpose of saving electricity is achieved.

In the embodiment of the present application, one HARQ process may maintain one first timer and one second timer, and a plurality of HARQ processes may also maintain one first timer and one second timer.

Taking as an example that one HARQ process may maintain one first timer and one second timer, different HARQ corresponds to different first timers and second timers. In an example, the HARQ process for the first CG resource usage includes: HARQ process 1, HARQ process 2 and HARQ process 3, wherein HARQ process 1 maintains a first timer a and a second timer a, HARQ process 2 maintains a first timer B and a second timer B, and HARQ process 3 maintains a first timer C and a second timer C.

Taking as an example that multiple HARQ processes may maintain one first timer and one second timer, different HARQ processes correspond to the same first timer and the same second timer. In an example, the HARQ process for the first CG resource usage includes: HARQ process 1, HARQ process 2, and HARQ process 3, wherein HARQ process 1, HARQ process 2, and HARQ process 3 together maintain a first timer D and a second timer D.

In the case of maintaining a first timer and a second timer for a HARQ process, the processing performed by the terminal device further includes:

in some embodiments, the first timer corresponds to the first HARQ process, and during operation of the first timer, the terminal device does not utilize a second CG resource for data transmission, the second CG resource corresponding to the first HARQ process.

And when the first timer corresponding to one HARQ process runs, the terminal equipment does not utilize the second CG resource of the HARQ process to transmit data.

In some embodiments, the terminal device receives a new transmission or retransmission schedule for the first HARQ process, stops the first timer, and performs new transmission of second uplink data or retransmission of the first uplink data based on the new transmission or retransmission schedule.

And when the terminal equipment receives the new transmission schedule or the retransmission schedule aiming at the first HARQ process, carrying out new transmission of second uplink data or retransmission of first uplink data based on the received new transmission schedule or retransmission schedule, and stopping a first timer maintained by the running first HARQ process.

In an example, when the terminal device receives a new transmission schedule for the first HARQ process, a new transmission of the second uplink data is performed based on the received new transmission schedule.

In an example, when the terminal device receives the retransmission schedule for the first HARQ process, the first uplink data is retransmitted based on the received retransmission schedule.

Optionally, the terminal device performs new transmission of the second uplink data or retransmission of the first uplink data by using a second DG resource of the first HARQ process, where the second DG resource is a resource dynamically scheduled to the terminal device by the network device through new transmission scheduling or retransmission scheduling.

Optionally, the terminal device performs new transmission of the second uplink data or retransmission of the first uplink data based on the second DG resource, starts a first timer, and monitors the PDCCH scrambled by the first RNTI during operation of the first timer.

In some embodiments, the terminal device receives a first downlink feedback indication (Downlink Feedback Information, DFI) indicating that data is received correctly or a second DFI indicating that data is not received correctly, stops the first timer, and performs new transmission of second uplink data or retransmission of the first uplink data based on the first DFI or the second DFI.

And if the terminal equipment receives the indication first DFI or the second DFI, carrying out new transmission of second uplink data or retransmission of the first uplink data based on the received first DFI or the received second DFI, and stopping a first timer maintained by the first HARQ process.

In an example, if the terminal device receives the first DFI, the terminal device does not perform a new transmission of the second uplink data based on the received first DFI.

In an example, the terminal device receives the second DFI, and then retransmits the first uplink data based on the received second DFI.

Optionally, the terminal device performs new transmission of the second uplink data or retransmission of the first uplink data by using the second CG resource of the first HARQ process.

Optionally, the terminal device performs new transmission of the second uplink data or retransmission of the first uplink data based on the second CG resource, starts the first timer, and monitors the PDCCH scrambled by the first RNTI during operation of the first timer. Wherein the second CG resource is a CG resource different from the first CG resource using the first HARQ process.

In this embodiment of the present application, the first CG resource and the second CG resource are CG resources with different time-frequency positions using the same HARQ process. Here, when the network device configures CG resources to the terminal device, the terminal device is provided with information about a set of CG resources, where the CG resources appear according to a certain rule (e.g., a period). These CG resources may bind one or more HARQ process numbers, e.g. 4 HARQ process numbers are allocated to CG resources by the network device, and CG resources with the same HARQ process may appear according to a certain time law. Assuming that the ID of the HARQ process used by the first CG resource is 0, after a period of time, data transmission is performed again by using the CG resource with the HARQ process ID of 0, and at this time, the CG resource with the HARQ process ID of 0 is used as the second CG resource.
