Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1, fig. 1 is a schematic diagram of a network structure to which the embodiment of the present invention is applicable, and as shown in fig. 1, the network structure includes a terminal 11 and a network side device 12, where the terminal 11 may be a User Equipment (UE) or other terminal devices, for example: the present invention relates to a Mobile terminal, and more particularly to a Mobile terminal, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), a robot, a vehicle, and other terminal-side devices. The network side device 12 may be a base station, for example: macro station, LTE eNB, 5G NR NB, etc.; the network side device may also be a small station, such as a Low Power Node (LPN), pico, femto, or the network side device may be an Access Point (AP); the network side device may also be a network node formed by a Central Unit (CU) and a plurality of Transmission Reception Points (TRPs) managed and controlled by the CU. It should be noted that, in the embodiment of the present invention, the specific type of the network-side device is not limited.

In addition, the repeated transmission in the embodiment of the present invention may be applied to repeated transmission in Carrier Aggregation (CA) and Dual Connectivity (DC) including, but not limited to, those shown in fig. 2.

In CA and DC scenarios, that is, one RB (corresponding to one PDCP entity) of the PDCP layer, is transmitted through a plurality of Logical channels (RLC entities) in a Radio Link Control (RLC) layer. For the CA model, multiple logical channels corresponding to the repeatedly transmitted RBs are processed by one MAC entity at a Media Access Control (MAC) layer, and data from different RLC logical channels are mapped to one or more carriers for transmission. For the DC model, the PDCP entity may send data corresponding to a Master Cell Group (MCG) to an RLC entity, and send data corresponding to a Secondary Cell Group (SCG) to an RLC entity, where multiple logical channels corresponding to the repeatedly transmitted rbs (duplicate rbs) are mapped to different MAC entities, and data of logical channels corresponding to different RLC entities are mapped to different carriers for transmission.

Referring to fig. 3, fig. 3 is a flowchart of a method for reporting a retransmission activation status according to an embodiment of the present invention, and as shown in fig. 3, the method includes the following steps:

301. the terminal sends a first signaling to the network side equipment, wherein the first signaling is used for notifying the repeated transmission activation state.

In an embodiment of the present invention, the repeated transmission activation state notified by the first signaling may be controlled by the terminal, that is, the terminal notifies a network side device of the repeated transmission activation state autonomously determined by the terminal. For example: the terminal can determine to activate or deactivate the repeated transmission of one or more RBs according to the terminal capacity, service requirement, equipment resource condition and other reasons, so that the network side equipment and the terminal can achieve consistent understanding of the repeated transmission activation state, thereby realizing timely and effective repeated transmission scheduling and transmission and improving the utilization rate of wireless resources. Furthermore, due to the fact that timely and effective repeated transmission scheduling and transmission can be achieved, the requirements for service time delay and reliability can be met. In addition, since the above-mentioned retransmission active state is determined by the terminal itself, the above-mentioned retransmission active state may also be referred to as an active state of the terminal with respect to retransmission.

It should be noted that the above-mentioned duplicate transmission activation state of the first signaling notification may be a duplicate transmission activation state that the terminal takes effect, that is, the terminal performs data transmission according to the duplicate transmission activation state of the first signaling notification. Or the above-mentioned repeated transmission activation state of the first signaling notification may be a repeated transmission activation state expected by the terminal, and the network side device may adjust or not adjust the repeated transmission activation state.

In addition, the first signaling may be used to notify the retransmission activation state, where the terminal notifies the network side device of the retransmission activation state by using explicit signaling.

In the embodiment of the invention, the terminal can inform the network side equipment of the repeated transmission activation state through the steps, so that the network side equipment and the terminal can achieve consistent understanding of the repeated transmission activation state, timely and effective repeated transmission scheduling and transmission are realized, and the utilization rate of wireless resources is improved.

As an optional implementation, the activation state includes at least one of the following:

Whether to activate the repeat transmission may be whether to activate the repeat transmission of RBs to which the terminal is fully or partially configured with repeat transmission.

The above-mentioned RB not activating the repeated transmission may mean that the repeated transmission of the RB is not activated, and of course, the above-mentioned RB not activating the repeated transmission may also mean that the RB deactivating the repeated transmission, that is, the repeated transmission of the RB is converted from the activated state to the deactivated state.

It should be noted that the representation form of the available carriers in the activation state may be different from that of the logical channel, that is, whether to activate the repeatedly transmitted RB or deactivate the repeatedly transmitted RB, for example: and when a plurality of logical channels of a certain RB indicate activation, the RB activates repeated transmission, and if a certain RB only activates one logical channel, the RB deactivates repeated transmission. That is, in some embodiments, the activation state may not include activation of a radio bearer RB for repeated transmission and deactivation of the RB for repeated transmission.

In addition, the available RLC entities, logical channels, and carriers for activating and deactivating the repeatedly transmitted RB may be pre-configured, for example: protocol conventions, network side configuration, etc., such that in some embodiments, the activation state may include only at least one of activating a repeatedly transmitted radio bearer RB and not activating a repeatedly transmitted RB.

In the above embodiment, when the terminal autonomously activates or deactivates the repeat transmission, the network side device can timely acquire the relevant information, thereby realizing timely and effective repeat transmission scheduling and transmission and improving the transmission performance.

As an optional implementation manner, the first signaling is: RRC signaling.

In this embodiment, the repeated transmission activation state can be notified by uplink RRC signaling.

Optionally, the RRC signaling is terminal Assistance Information (UE Assistance Information), where the terminal Assistance Information includes the activation state; or

The above-mentioned repeated transmission activation status report is a new RRC signaling newly introduced in the embodiment of the present invention.

In the above embodiment, the terminal can report the repeated transmission activation state in the terminal auxiliary Information report (UE Assistance Information); or, a new RRC signaling for repeatedly transmitting the activation state report is introduced to report the repeatedly transmitting activation state.

As an optional implementation manner, the first signaling is: MAC layer control signaling.

In this embodiment, the duplicate transmission activation state may be notified by uplink MAC signaling.

Optionally, the MAC layer control signaling includes:

The first signaling may indicate that all RBs configured with repeat transmission of the terminal activate repeat transmission or deactivate repeat transmission, so that the overhead of MAC signaling may be saved.

For example: the first MAC signaling only has one MAC subheader, and all radio bearer RBs configured with repeated transmission of the terminal are indicated to activate repeated transmission or deactivate repeated transmission through LCID of the MAC subheader.

Wherein, only one MAC subheader of the first MAC signaling may be, for example, that the first MAC signaling only has one MAC subheader and does not have a corresponding message part, such as: there is no MAC CE. And the first MAC signaling may be as shown in fig. 4, where the MAC signaling indicates that all RBs configured with repeat transmission activate or deactivate repeat transmission at the same time, and may use two LCIDs to respectively indicate activation and deactivation of repeat transmission, where the MAC CE has only one MAC subheader and no corresponding message part.

The second MAC signaling may indicate a retransmission activation status of each RB configured with retransmission through a bitmap.

For example: the second MAC signaling comprises an MAC sub-header and an MAC CE, the MAC CE is indicated by the LCID of the MAC sub-header to be used for indicating the activation state of repeated transmission, and the MAC CE indicates the activation state of repeated transmission of the RB configured with repeated transmission in a bitmap mode.

The second MAC signaling includes one MAC subheader and one MAC CE, but is not limited thereto, and the second MAC signaling only includes one MAC subheader and one MAC CE.

The second MAC signaling may refer to fig. 5 and fig. 6, as shown in fig. 5, the MAC signaling indicates activated and/or deactivated RBs, and indicates, in the MAC subheader, that the MAC CE repeatedly transmits the uplink MAC CE for activation/deactivation by using 1 LCID value, as shown in fig. 6, each bit in the MAC CE corresponds to an RB configured with repeated transmission. For example: 1 indicates activation and 0 indicates deactivation.

And the third MAC signaling may indicate, through the MAC CE, an activation state of each logical channel corresponding to an RB that activates repeated transmission and an activation state of each logical channel corresponding to an RB that deactivates repeated transmission.

For example: the third MAC signaling comprises a MAC sub-header and a MAC CE, the MAC CE is indicated by the LCID of the MAC sub-header to indicate the activation state of the repeated transmission, the MAC CE indicates the identification of the RB which activates the repeated transmission and indicates the activation state of each logical channel corresponding to the RB which activates the repeated transmission, and/or indicates the identification of the RB which deactivates the repeated transmission and indicates the activation state of each logical channel corresponding to the RB which deactivates the repeated transmission.

The third MAC signaling includes, but is not limited to, one MAC subheader and one MAC CE, the second MAC signaling includes only one MAC subheader and one MAC CE, and the MAC CE is a fixed length or a variable length. In addition, the identification of the RB (RB ID) may be an RB number for which the repeated transmission is configured.

The MAC subheader of the third MAC signaling may refer to the MAC subheader of the second MAC signaling, and further, the third MAC signaling may further indicate a retransmission activation state of the RB configured with retransmission in a bitmap form, for example: such as the MAC CE shown in fig. 6. In addition, the third MAC signaling may indicate that the RB ID may be 5 bits as shown in fig. 7 or 3 bits, the MAC CE may be a fixed length or a variable length, and when the MAC CE is the fixed length, each RB configured with repeated transmission may be indicated in the MAC CE; when variable length, there is an indication of the corresponding RB in the MAC CE only when one RB activates a repeat transmission. L1, L2, and L3 in fig. 7 correspond to the logical channel associated with the previous RB ID, and setting 0 indicates that the logical channel is inactive (data cannot be transmitted), and setting 1 indicates that the logical channel is active (data can be transmitted).

And the fourth MAC signaling may indicate the activation status of each logical channel and the available carriers of each logical channel through the MAC CE.

For example: the fourth MAC signaling comprises a MAC sub-header and a MAC CE, the MAC CE is indicated by the LCID of the MAC sub-header to indicate the activation state of the repeated transmission, the MAC CE indicates the identification of the activated repeated transmission RB, indicates the activation state of each logical channel corresponding to the activated repeated transmission RB, and indicates the available carrier of each logical channel corresponding to the activated repeated transmission RB, and/or indicates the identification of the deactivated repeated transmission RB, indicates the activation state of each logical channel corresponding to the deactivated repeated transmission RB, and indicates the available carrier of each logical channel corresponding to the deactivated repeated transmission RB.

Optionally, the terminal may obtain repeat transmission configuration information configured by the network side, where the configuration information is used to configure carriers usable by each logical channel when the RB capable of performing repeat transmission performs repeat transmission by using different logical channels and/or logical channel combinations.

Here, the usable carrier may be understood as a usable carrier corresponding to each logical channel, and the terminal may select an usable carrier of each logical channel from the usable carriers. For example: before the terminal sends the MAC signaling, the network side device configures the terminal with carriers corresponding to each logical channel, for example, the usable carriers configured by the logical channel L3 are C0, C1, and C2, so that the terminal can configure the C0 with the usable carrier of the logical channel 1 when indicating.

The fourth MAC signaling may further indicate an activation state of each logical channel corresponding to activating and/or deactivating the repeatedly transmitted RB and an available carrier of each logical channel in a manner as shown in fig. 8. For example: usable carriers configured by the logical channel L3 are C0, C1 and C2, usable carriers configured by the logical channel L2 are C3, C4 and C5, usable carriers configured by the logical channel L1 are C6 and C7, then the RB ID1 may be set to be different by bit values of L1, L2 and L3 to indicate an activation state of each logical channel, and the bit values of C0, C1, C2, C3, C4, C1, C6 and C7 are set to be different to indicate whether its corresponding carrier is an usable carrier of the corresponding logical channel.

In addition, the fourth MAC signaling may additionally indicate a duplicate transmission activation status of an RB configured with duplicate transmission, but of course, the indication is not also sufficient, because the activation status of the corresponding RB may be implicitly indicated by a status of a logical channel, for example: and if only one logical channel is activated, the corresponding RB does not activate the repeat transmission.

It should be noted that the first MAC signaling, the second MAC signaling, the third MAC signaling, and the fourth MAC signaling may be understood as MAC signaling in different MAC CE formats.

As an optional implementation manner, the first signaling is used to notify a repeated transmission activation state of the downlink RB and/or the uplink RB.

In this embodiment, the terminal can control the repeated transmission activation state of the downlink RB and can also control the repeated transmission activation state of the uplink RB, so that the network side device and the terminal can achieve consistent understanding of the repeated transmission activation state, thereby achieving timely and effective repeated transmission scheduling and transmission, and improving the utilization rate of radio resources.

As an optional implementation, the method further comprises:

In this embodiment, the repeated transmission activation state of the RB can be directly controlled by the terminal, and the terminal performs data transmission according to the repeated transmission activation state controlled by the terminal.

As an optional implementation, the method further comprises:

after the terminal sends the first signaling to the network side device, the method further includes:

The second signaling may be a downlink repeat activation/deactivation command.

In this embodiment, after receiving the first signaling, the network side device returns a second signaling to the terminal to confirm the repeated transmission activation state notified by the first signaling, so as to avoid data transmission errors between the terminal and the network side device. Further, the method further comprises: and under the condition that the second signaling is used for confirming the repeated transmission activation state of the first signaling notification, the terminal transmits data according to the repeated transmission activation state of the first signaling notification.

In addition, the activation state of the repeated transmission determined by the network side device based on the activation state of the repeated transmission notified by the first signaling, that is, the network side device adjusts the activation state of the repeated transmission autonomously controlled by the terminal, so that the network side device adjusts the activation state of the repeated transmission reported by the terminal, and the transmission performance of the determined activation state of the repeated transmission is better. Further, the second signaling is used to notify the terminal to perform data transmission according to the repeated transmission activation state notified by the second signaling, so that the terminal may perform data transmission according to the repeated transmission activation state notified by the second signaling.

In the embodiment of the invention, a terminal sends a first signaling to a network side device, and the first signaling is used for notifying the repeated transmission activation state. Therefore, the terminal can inform the network side equipment of the repeated transmission activation state, so that the network side equipment and the terminal can achieve consistent understanding of the repeated transmission activation state, timely and effective repeated transmission scheduling and transmission are realized, and the utilization rate of wireless resources is improved.
