The present disclosure relates to the field of communication technologies, and in particular, to an information processing method, device, and equipment.
In the fifth generation mobile communication systems (5G or New Radio (NR) systems), the network bandwidth may be much larger than the terminal transmission bandwidth (the network bandwidth can be configured to a maximum of 400 MHz). However, the capabilities of user equipment (UEs) are different. For example, the capabilities of some UEs may not support such a large bandwidth, for example, for the purpose of power saving or the like.
The bandwidth part (BWP) configuration scenarios in the related art are as shown in
The numerology is a description of physical characteristics. The characteristics in numerology include: different subcarrier spaces (SCSs), different transmission time intervals (TTIs), etc. Different numerologies are provided with different parameters to meet different service requirements. For example, some services require shorter TTI duration, etc. In practical applications, the network side copes with various requirements by configuring different BWPs.
However, the UE can activate only a single BWP for one cell. Assuming that BWP1 and BWP2 both belong to a same cell, only one BWP can be activated for the UE at a time, i.e. the UE activates either BWP1 or BWP2. The UE may perform signaling and data transmission in an activated BWP and may switch between different BWPs. In the standardization discussion in the related art, it is agreed that retransmission can be performed between different BWPs, that is, the same hybrid automatic repeat request (HARQ) can be switched between different BWPs.
Configured grant scheduling refers to a transmission mode in which resources are allocated and scheduled in advance, and specifically includes: semi-persistent scheduling (SPS), and configured scheduling based on radio resource control (RRC) configuration.
In the discussion on NR, a scheme in which a downlink (DL) feedback channel is removed is employed. That is, after the uplink (UL) data is transmitted, there is no feedback channel similar to a physical hybrid ARQ indicator channel (PHICH) in Long Term Evolution (LTE), instead, a downlink control information (DCI) indication mode is used. If the UL data is transmitted incorrectly, the network side transmits retransmission DCI to request a retransmission, and if the UL data is transmitted correctly, the DCI is used to schedule the same HARQ process to perform a new transmission.
However, in the process of configured grant scheduling, the manner in which a new transmission is performed does not need to be indicated by the DCI. Instead, a new transmission is automatically triggered when certain time conditions are met. Therefore, this will result in that the UE is unable to ascertain when the HARQ process may be cleared off to perform a new transmission. As a result, a configured grant timer is defined.
However, there is no configuration and maintenance schemes for the configured grant timer in the related art, so that the accuracy of data transmission cannot be determined.

Specific embodiments of the present disclosure will be described in further detail below with reference to the accompanying drawings and examples. The following examples are intended to illustrate the present disclosure, but are not intended to limit the scope of the present disclosure.
As shown in
The duration of the configured grant timer may be set by the network side according to different application environments or scenarios. The configured grant timer is used for recording whether a resource grant is valid. After the UE performs an initial transmission or retransmission, the configured grant timer is started. If the configured grant timer expires, the HARQ process of the resource grant is terminated and the corresponding transmission is delivered to a physical layer; when a scheduling command for the HARQ process is received (new transmission/retransmission), the configured grant timer is started or restarted.
The duration of the configured grant timer is configured independently for one or more of the following reference parameters: bandwidth part (BWP), transmission time interval (TTI) duration, uplink carrier, numerology or subcarrier space (SCS) corresponding to the numerology, or serving cell.
In the embodiment of the present disclosure, the configured grant timers may be configured independently for different reference parameters, respectively. Specifically, when the reference parameter is BWP, a configured grant timer is independently configured for each BWP; or when the reference parameter is TTI duration, a configured grant timer is independently configured for each TTI; or when the reference parameter is uplink carrier, a configured grant timer is independently configured for each uplink carrier; or when the reference parameter is numerology or SCS corresponding to the numerology, a configured grant timer is independently configured for each numerology or SCS corresponding to the numerology; or when the reference parameter is serving cell, a configured grant timer is configured for each serving cell.
The starting position of the configured grant timer is the starting position of a subframe where the data transmission moment is located, or the starting position of the configured grant timer is the current slot of data transmission. The unit of the duration of the configured grant timer includes: subframe, symbol, or slot.
For example, assuming that the reference parameter is BWP which include BWP1 and BWP2, configured grant timers may be configured for BWP1 and BWP2, respectively. It is assumed the configured grant timers have duration T1 and T2, respectively.
In addition, in order to further facilitate the determination of the accuracy of data transmission, the configuration information further includes: timer running indication information, where the timer running indication information is used to indicate to the UE any one or more of following information: when the reference parameter is BWP, if a change of BWP occurs, a configured grant timer corresponding to a BWP before the change or corresponding to a BWP after the change is run during the change of BWP to maintain a hybrid automatic repeat request HARQ process in the BWP before the change; when configured grant scheduling information is received or retransmission is initiated in the BWP after the change, a configured grant timer corresponding to the BWP after the change is run; when the reference parameter is TTI duration, if a change of TTI occurs, a configured grant timer corresponding to TTI duration before the change or corresponding to TTI duration after the change is run during the change of TTI to maintain an HARQ process in the TTI duration before the change; when the configured grant scheduling information is received or retransmission is initiated in the TTI duration after the change, a configured grant timer corresponding to the TTI duration after the change is run; when the reference parameter is uplink carrier, if a change of uplink carrier occurs, a configured grant timer corresponding to an uplink carrier before the change or corresponding to an uplink carrier after the change is run during the change of uplink carrier to maintain an HARQ process on the uplink carrier before the change; when the configured grant scheduling information is received or retransmission is initiated on the uplink carrier after the change, a configured grant timer corresponding to the uplink carrier after the change is run.
In the embodiment of the present disclosure, the network side transmits acquired duration of the configured grant timer to the UE, so that the UE side can perform data transmission according to the duration of the configured grant timer and the acquired configured grant scheduling information, and maintain the state of the grant timer, thereby determining the data transmission accuracy, and further arranging an effective retransmission or initiating a new transmission in time. Thus, the data transmission accuracy, the data transmission efficiency and the resource utilization rate are improved.
As shown in
A step 301: receiving configuration information transmitted by a network side, where the configuration information includes duration of a configured grant timer.
The duration of the configured grant timer is configured independently for one or more of the following reference parameters: BWP, TTI duration, uplink carrier, numerology or SCS corresponding to the numerology, or serving cell.
The starting position of the configured grant timer is the starting position of the subframe where the data transmission moment is located, or the starting position of the configured grant timer is the current slot of data transmission. A unit of the duration of the configured grant timer includes: subframe, symbol, or slot.
A step 302: performing data transmission according to the configuration information, and maintaining a state of the configured grant timer.
Specifically, in this step, the UE acquires the timer duration of the target configured grant timer according to current transmission characteristics. The transmission characteristics include BWP, TTI duration, uplink carrier, numerology or SCS corresponding to the numerology, serving cell.
When there is data to be transmitted in the HARQ process, a data packet is transmitted, and the target configured grant timer is started or restarted; and when it is determined according to the duration of the target configured grant timer that the target configured grant timer expires, the HARQ process is terminated and the target configured grant timer is stopped.
In addition, in order to further facilitate the determination of the accuracy of data transmission, the configuration information further includes: timer running indication information, where the timer running indication information is used to indicate any one or more of the following information: when the reference parameter includes BWP, if a change of BWP occurs, running a configured grant timer corresponding to a BWP before the change or corresponding to a BWP after the change during the change of BWP to maintain a hybrid automatic repeat request HARQ process in the BWP before the change; when configured grant scheduling information is received or retransmission is initiated in the BWP after the change, running a configured grant timer corresponding to the BWP after the change; when the reference parameter includes TTI duration, if a change of TTI occurs, running a configured grant timer corresponding to TTI duration before the change or corresponding to TTI duration after the change during the change of TTI to maintain the HARQ process in the TTI duration before the change; when the configured grant scheduling information is received or retransmission is initiated in the TTI duration after the change, running a configured grant timer corresponding to the TTI duration after the change; when the reference parameter includes uplink carrier, if a change of uplink carrier occurs, running a configured grant timer corresponding to an uplink carrier before the change or corresponding to an uplink carrier after the change during the change of uplink carrier to maintain an HARQ process on the uplink carrier before the change; when the configured grant scheduling information is received or retransmission is initiated on the uplink carrier after the change, running a configured grant timer corresponding to the uplink carrier after the change.
For example, according to the timer running indication information, if a change of BWP, assuming that a BWP1 is changed to a BWP2, occurs during data transmission by the UE, a configured grant timer corresponding to the BWP1 before the change or corresponding to the BWP2 after the change is run during the change of BWP, to maintain an HARQ process in the BWP1 before the change; when configured grant scheduling information is received or a retransmission is initiated in the BWP2 after the change, a configured grant timer corresponding to the BWP2 after the change is run.
In the embodiment of the disclosure, the network side transmits the acquired duration of the configured grant timer to the UE, so that the UE side can perform data transmission according to the duration of the configured grant timer and the acquired configured grant scheduling information, and maintain the state of the grant timer, thereby determining the data transmission accuracy, and further arranging an effective retransmission or initiating a new transmission in time. Thus, the data transmission accuracy, the data transmission efficiency and the resource utilization rate are improved.
Hereinafter, an implementation process of the information processing method according to the embodiment of the present disclosure is described with reference to different reference parameters.
In this embodiment, a description is given by taking configuring different configured grant timers based on duration of TTIs as an example. As shown in
A step 401: a network side transmits configuration information to UE.
The configuration information includes: configured grant scheduling information, duration of a configured grant timer and corresponding TTI duration.
In the embodiment of the present disclosure, the duration of the configured grant timer is set to corresponding values based on different TTI duration.
In addition, the configuration information may further include timer running indication information, where the timer running indication information is used to indicate to the UE: if a change of TTI occurs, a configured grant timer corresponding to TTI duration before the change or corresponding to TTI duration after the change is run during the change of TTI to maintain the HARQ process in the TTI duration before the change; when the configured grant scheduling information is received or retransmission is initiated in the TTI duration after the change, a configured grant timer corresponding to the TTI duration after the change is run.
As shown in
A step 402: UE performs data transmission according to the configured grant scheduling information and the configuration information, and maintains a state of the configured grant timer.
Specifically, when there is data to be transmitted in an HARQ process, the UE transmits a data packet, and starts or restarts the configured grant timer. When the timer expires, the data in the process is delivered to a physical layer. When a scheduling command (new transmission/retransmission) for this HARQ process is received, the UE starts or restarts the configured grant timer.
If the configuration information further includes timer running indication information, if a change of TTI occurs in the process of data transmission, a configured grant timer corresponding to TTI duration before the change or corresponding to TTI duration after the change is run during the change of TTI, to maintain the HARQ process in the TTI duration before the change; when the configured grant scheduling information is received or retransmission is initiated in the TTI duration after the change, a configured grant timer corresponding to the TTI duration after the change is run.
For example, if a change of TTI, assuming that a TTI 1 is changed to a TTI 2, occurs during data transmission, the UE runs a configured grant timer corresponding to TTI 1 before the change or corresponding to TTI 2 after the change during the change of TTI, to maintain the HARQ process in the TTI 1 before the change; and when configured grant scheduling information is received or retransmission is initiated in the TTI 2 after the change, the UE runs a configured grant timer corresponding to the TTI 2 after the change.
In this embodiment, a description is given by taking configuring different configured grant timers based on lengths of BWPs as an example. As shown in
A step 601: a network side transmits configuration information to UE.
The configuration information includes: configured grant scheduling information, the duration of the configured grant timer and corresponding length of BWP.
In the embodiment of the present disclosure, duration of the configured grant timer is set to corresponding values based on different lengths of BWPs.
In addition, the configuration information may further include timer running indication information, where the timer running indication information is used to indicate to the UE: if a change of BWP occurs, running a configured grant timer corresponding to a BWP before the change or corresponding to a BWP after the change during the change of BWP to maintain a hybrid automatic repeat request HARQ process in the BWP before the change; when the configured grant scheduling information is received or retransmission is initiated in the BWP after the change, running a configured grant timer corresponding to the BWP after the change.
In the case of different BWPs, as shown in
A step 602: the UE performs data transmission according to the configured grant scheduling information and the configuration information, and maintains a state of the configured grant timer.
Specifically, when there is data to be transmitted in an HARQ process, the UE transmits a data packet, and starts or restarts the configured grant timer. When the timer expires, the data in the process is delivered to a physical layer. When a scheduling command (new transmission/retransmission) for this HARQ process is received, the UE starts or restarts the configured grant timer.
If the configuration information further includes timer running indication information, if a change of BWP occurs in the process of data transmission, a configured grant timer corresponding to a BWP before the change or corresponding to a BWP after the change is run during the change of BWP to maintain a hybrid automatic repeat request HARQ process in the BWP before the change; and when the configured grant scheduling information is received or retransmission is initiated in the BWP after the change, a configured grant timer corresponding to the BWP after the change is run.
For example, if a change of BWP, assuming that a BWP1 is changed to a BWP2, occurs during data transmission by the UE, the configured grant timer corresponding to the BWP1 before the change or corresponding to the BWP2 after the change is run during the change of BWP, to maintain the HARQ process in the BWP1 before the change; when the configured grant scheduling information is received or a retransmission is initiated in the BWP2 after the change, the configured grant timer corresponding to the BWP2 after the change is run.
As shown in
In an embodiment of the present disclosure, the duration of the configured grant timer may also be configured for different uplink carriers. The duration of the configured grant timer can be transmitted to the UE through the configuration information. For example, the duration of the supplementary uplink (SUL) configured grant timer corresponding to the uplink carrier 1 is T1, and the duration of the SUL configured grant timer corresponding to the uplink carrier 2 is T2. Also, in the embodiment of the present disclosure, the configuration information further includes timer running indication information, where the timer running indication information is used to indicate to the UE: if a change of uplink carrier occurs, running a configured grant timer corresponding to an uplink carrier before the change or corresponding to an uplink carrier after the change during the change of uplink carrier so as to maintain the HARQ process on the uplink carrier before the change; and when the configured grant scheduling information is received or retransmission is initiated on the uplink carrier after the change, running a configured grant timer corresponding to the uplink carrier after the change.
Then, if a change of uplink carrier occurs in the subsequent data transmission process by the UE, a configured grant timer corresponding to the uplink carrier before the change or corresponding to the uplink carrier after the change is run during the change of uplink carrier to maintain the HARQ process on the uplink carrier before the change; and when the configured grant scheduling information is received or retransmission is initiated on the uplink carrier after the change, the configured grant timer corresponding to the uplink carrier after the change is run.

For example, the duration of the SUL configured grant timer corresponding to the SCS1 is T5, and the duration of the SUL configured grant timer corresponding to the SCS2 is T6. For other processes of this embodiment, references may be made to descriptions of
In an embodiment of the present disclosure, the duration of the configured grant timer may also be configured for different serving cells.
