Network side devices, etc.

In a 5G system, in a dual connectivity (DC) scenario, multiple network nodes (Cell Groups, CGs) can serve terminal devices, and replica data can be transmitted between cell groups and terminal devices. .

It should be understood that in the embodiment of the present application, the CG may be equivalent to a network node or a network device or the like.

Optionally, in the DC scenario, the protocol structure of the data replication transmission mode may be as shown in FIG. 1 . The data replication transmission method adopts a protocol scheme of a split bearer. For the uplink and downlink, the Packet Data Convergence Protocol (PDCP) is located in a certain CG (Master CG (MCG) or SCG (Secondary CG, SCG)), which is the anchor CG (anchor). CG). In any CG, PDCP can copy PDCP Protocol Data Units (PDUs) into the same two copies, such as one PDCP PDU, one Duplicated PDCP PDU, and two PDCPs through different CG wireless. The Link Control (RLC) layer and the Media Access Control (MAC) layer arrive at the terminal (downlink) or the base station (uplink) corresponding MAC and RLC layers through the air interface, and finally converge to the PDCP. The PDCP layer detects that two PDCPs are the same duplicate version, that is, discard one of them and submit the other to the upper layer.

In addition, in the carrier aggregation scenario, the PDCP entity can support the data replication function, that is, the PDCP replication data function is used, so that the copied data is separately transmitted to two Radio Link Control (RLC) entities (corresponding to two Different logical channels), and finally ensure that the copied PDCP PDUs can be transmitted on different physical layer aggregate carriers to achieve frequency diversity gain to improve data transmission reliability.

The specific protocol structure will be described below in conjunction with FIG. As shown in FIG. 2, the PDCP entity corresponding to a radio bearer has a split bearer replication function, and the data process of the PDCP service data unit (SDU) is copied and encapsulated into two PDCP PDU1, and the two PDCP PDUs have the same The content, that is, the data payload and the header header are the same. The two PDCP PDUs and the PDCP PDUs are respectively mapped to different Radio Link Control (RLC) entities, and different RLC entities correspond to different logical channels. For Media Access Control (MAC), After learning which logical channels transmit the duplicate data of the same PDCP PDU, the replicated data is transmitted on different carriers, for example, the replicated data transmitted in one RLC entity is transmitted on the physical carrier 1, and the other RLC entity is The transmitted duplicate data is transmitted on physical carrier 2.

In the existing discussion of NR, for a radio bearer configured with a duplicate data transmission function, a MAC-control element (Control Element, CE) can be used to dynamically activate or de-activate a data transfer of a bearer. Transfer function.

When a media access control (MAC) entity receives an uplink scheduling resource or acquires a pre-configured resource, it may start a Link Control Protocol (LCP) process, where the LCP process includes starting to generate a MAC PDU (wherein , Protocol Data Unit (PDU). When data on each logical channel is transmitted on the resource, the amount of transmission is determined by some configuration parameters of the logical channel, such as Priority Bit Rate (PBR), B _j . Where subscript _j in B _j represents which of the corresponding logical channels.

When establishing a logical channel, the MAC entity may initialize the logical channel B _{j to} be zero. For each logical channel, in the LCP procedure, B _j may be increased according to PBR×T, where Bj is the distance from the last update. time. If the value of B _j is greater than a specific value (bucket size, ie, PBR × BSD), B _{j is} set to the specific value.

When performing a new transmission, the MAC entity may allocate resources for the logical channel, the MAC entity may allocate resources for the logical channel whose B _{j is} greater than 0, and may lower the B _{j of the} corresponding logical channel based on the processed MAC SDU. The value of B _j can be a negative value.

When the data replication function of a radio bearer is deactivated, the RLC layer of one of the logical channels does not receive the data of the PDCP layer, and the buffered data is also cleared; in this case, the Bj value of the logical channel. Always updated, since the RLC of the logical channel will never transmit data, its B _j is likely to reach the maximum value of PBR*BSD (bucket size duration); at this time, the _{Bj of the} RLC layer of another logical channel is updated. But B _j will subtract the corresponding service data size each time it gets transmitted. Thus, when the data replication function of the radio bearer is reactivated, the _Bj (one maximum value, one normal update value) of the two RLCs causes the service data sizes of the two RLCs to be different.

To this end, the embodiments of the present application provide the following methods, which can solve the problem. Among them, the configuration parameter values mentioned below are the above mentioned B _j .

FIG. 3 is a schematic flowchart of a wireless communication method 100 according to an embodiment of the present application. The method can optionally be performed by a terminal device. The method 100 includes at least a portion of the following.

In 110, in a case where it is determined that the data replication function of the radio bearer transitions from the first deactivated state to the first activated state, the configuration parameter value of the first logical channel and the second logical channel are respectively determined based on the same initial value. The configuration parameter value is updated, wherein, in the first activation state, the first logical channel and the second logical channel transmit the same duplicate data, where the configuration parameter value is a parameter configured by the RRC layer to the logical channel by the RRC layer. value.

Optionally, when the logical channel is established, the initial value of the configuration parameter value is 0, and one logical channel corresponds to one RLC entity.

Optionally, the first logical channel and the second logical channel may be a logical channel for transmitting duplicate data in a CA scenario, or may be a logical channel for transmitting duplicate data in a DC scenario.

Optionally, in the activated state, the PDCP entity delivers data to the corresponding RLC entity of the first logical channel and the second logical channel; and in the deactivated state, the PDCP entity transmits data to the PLC entity corresponding to the first logical channel, The data is not passed to the RLC entity corresponding to the second logical channel.

Optionally, the first logical channel and the second logical channel are logical channels corresponding to data radio bearers, or logical channels corresponding to signaling radio bearers.

In order to facilitate a clearer understanding of the present application, how to make the configuration parameter value of the first logical channel the same as the configuration parameter value of the second logical channel will be described below in combination with several implementations.

In an implementation manner, when it is determined that the data replication function of the radio bearer changes from the first deactivated state to the first activated state, setting a configuration parameter value of the second logical channel to the first logic The configuration parameter value currently existing in the channel, wherein in the first deactivated state, the first logical channel instead of the second logical channel is used for transmission.

That is, in the case that the data copy function transitions from the first deactivated state to the first activated state, since the first logical channel has been processing data normally, the current configuration parameter value of the first logical channel can be acquired. The configuration parameter value of the second logical channel is set to the current configuration parameter value of the first logical channel.

In an implementation manner, the configuration of the first logical channel and the second logical channel is reset in a case where it is determined that the data replication function of the wireless bearer changes from the first deactivated state to the first activated state. The parameter value is the initial value. Optionally, the initial value is zero.

That is to say, in a case where the data copy function is changed from the first deactivated state to the first activated state, since the configuration parameter value of the first logical channel and the configuration parameter value of the second logical channel are different, the two can be reset. The configuration parameter value of the logical channel is such that the configuration parameter values of the two logical channels after reconfiguration are the same.

In an implementation manner, the configuration parameter value of the second logical channel is updated along with the configuration parameter value of the first logical channel during the data deactivation function.

That is, after the data copy function transitions from the second active state to the first deactivated state, during the first deactivated state, since the first logical channel is always processing data normally, the first logical channel can be based on the real time. a configuration parameter value, updating a configuration parameter value of the second logical channel, and a configuration parameter value of the first logical channel and a configuration parameter value of the second logical channel when the data replication function transitions from the first deactivated state to the first activated state Always consistent.

Optionally, in the case of transitioning from the second active state to the first deactivated state, the configuration parameter value of the second logical channel is suspended for updating. And further, in the case of transitioning from the first deactivated state to the first activated state, the updating of the configuration parameter values of the second logical channel may be re-opened. It should be understood that this implementation may not be applicable to 110, that is, it is not necessary to set the configuration parameter value of the first logical channel and the configuration parameter value of the second logical channel to the same value. For example, the configuration parameter values of the first logical channel and the second logical channel may not be changed by the transition from the deactivated state to the activated state due to the copy data function.

Optionally, in the case of transitioning from the second active state to the first deactivated state, the configuration parameter value of the second logical channel is set to zero. If the update is further suspended, in the case of transitioning from the first deactivated state to the first activated state, the update of the configuration parameter value of the second logical channel may be re-opened. It should be understood that this implementation may not be applicable to 110, that is, it is not necessary to set the configuration parameter value of the first logical channel and the configuration parameter value of the second logical channel to the same value. For example, the configuration parameter values of the first logical channel and the second logical channel may not be changed by the transition from the deactivated state to the activated state due to the copy data function.

In 120, a data size of the first logical channel to be served is determined based on the updated configuration parameter value of the first logical channel.

In 130, a data size of the second logical channel to be served is determined based on the updated configuration parameter value of the second logical channel.

It should be understood that the execution of 120 and 130 is in no particular order.

Therefore, in the embodiment of the present application, in a case where it is determined that the data copy function of the radio bearer is changed from the first deactivated state to the first activated state, the configuration parameter values of the first logical channel are respectively based on the same initial value. The value of the configuration parameter of the second logical channel is updated, so that the initial values of the configuration parameter values of the first logical channel and the second logical channel are different, and the subsequent determination of the service data size to be transmitted differs greatly. The problem of uneven distribution of transmission resources.
