Detailed Description
Technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be understood that the technical solutions of the embodiments of the present application may be applied to various communication systems, for example: a Global System for Mobile communications (GSM) System, a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) System, a Long Term Evolution (Long Term Evolution) System, an LTE (Frequency Division Duplex) System, an LTE Time Division Duplex (FDD) System, a Time Division Duplex (TDD), a Universal Mobile Telecommunications System (UMTS), and a future 5G Communication System.
Various embodiments are described herein in connection with a terminal device. A terminal device may also refer to a User Equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a User terminal, a wireless communication device, a User agent, or a User Equipment. An access terminal may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with Wireless communication capability, a computing device or other processing device connected to a Wireless modem, a vehicle mounted device, a wearable device, a terminal device in a future 5G Network or a terminal device in a future evolved Public Land Mobile Network (PLMN) Network, etc.
Various embodiments are described herein in connection with a network device. The network device may be a device for communicating with the terminal device, and for example, may be a Base Transceiver Station (BTS) in a GSM system or a CDMA system, a Base Station (NodeB, NB) in a WCDMA system, an evolved Node B (eNB, or eNodeB) in an LTE system, or may be a relay Station, an access point, a vehicle-mounted device, a wearable device, and a network-side device in a future 5G network or a network-side device in a future evolved PLMN network.
In a 5G system, in a Dual Connectivity (DC) scenario, multiple network nodes (Cell groups (CGs)) may serve a terminal device, and duplicate data may be transmitted between the Cell groups and the terminal device.
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, etc.
Alternatively, in the DC scenario, the protocol architecture of the data replication transmission scheme may be as shown in fig. 1. The data replication transmission mode adopts a protocol architecture of a split bearer (split bearer). For uplink and downlink, a Packet Data Convergence Protocol (PDCP) is located at a CG (Master CG, MCG) or SCG (Secondary CG, SCG), which is an anchor CG (anchor CG). In any CG, the PDCP may copy a PDCP Protocol Data Unit (PDU) into two identical copies, for example, one is a PDCP PDU, and the other is a copied PDCP PDU, where the two PDCP layers pass through a Radio Link Control (RLC) layer and a Media Access Control (MAC) layer of different CGs, and arrive at a corresponding MAC and RLC layer of a terminal (downlink) or a base station (uplink) through an air interface, and finally converge to the PDCP, and the PDCP layer monitors that the two PDCP layers are the same copied version, that is, one of the two PDCP layers is discarded, and the other PDCP layer is delivered to an upper layer.
In addition, in a carrier aggregation scenario, the PDCP entity may support a data duplication function, that is, the data duplication function of the PDCP entity is utilized, so that duplicated data is respectively transmitted to two Radio Link Control (RLC) entities (corresponding to two different logical channels), and it is finally ensured that the duplicated PDCP PDUs can be transmitted on aggregated carriers of different physical layers, thereby achieving a frequency diversity gain and improving data transmission reliability.
A specific protocol structure will be described below with reference to fig. 2. As shown in fig. 2, the PDCP entity corresponding to a certain radio bearer has a split bearer replication function, and copies and encapsulates the Data process of a PDCP Service Data Unit (SDU) into two PDCP PDUs 1, where the two PDCP PDUs have the same content, that is, the Data payload and the header of the bearer are the same. The two PDCP PDUs 1 and PDCP PDUs are respectively mapped to different Radio Link Control (RLC) entities, where the different RLC entities correspond to different logical channels, and for Media Access Control (MAC), after knowing which logical channels transmit duplicate data of the same PDCP PDU, the duplicate data are transmitted on different carriers, for example, the duplicate data transmitted in one RLC entity is transmitted on a physical carrier 1, and the duplicate data transmitted in another RLC entity is transmitted on a physical carrier 2.
In the conventional discussion of NR, for a radio bearer configured with a duplicated data transmission function, the data duplication transmission function of one bearer may be dynamically activated (activated) or deactivated (de-activated) by a MAC Control Element (CE).
When a Media Access Control (MAC) entity receives an uplink scheduling resource or acquires a pre-configured resource, a Link Control Protocol (LCP) procedure may be started, where the LCP procedure includes starting generation of a MAC PDU (Protocol Data Unit, PDU). When data on each logical channel is transmitted on the resource, the transmission amount is determined by some configuration parameters of the logical channel, such as Priority Bit Rate (PBR), Bj. Wherein, BjThe index j in (a) represents which on the corresponding logical channel.
When establishing a logical channel, the MAC entity may initialize B of the logical channeljTo zero, for each logical channel, in the LCP procedure, B can be increased according to PBR × TjWhere Bj is the time since the last update. If B is presentjIs greater than a certain value (bucket size, i.e., PBR. times. BSD), then B is addedjSet to the particular value.
When performing a new transmission, the MAC entity may allocate resources for the logical channel and the MAC entity may be BjLogical channel allocation resources greater than 0, B of the corresponding logical channel can be lowered based on the already processed MAC SDUj。BjThe value of (d) may be a negative value.
When the data copying function of one radio bearer is deactivated, the RLC layer of one logical channel cannot obtain the data of the PDCP layer, and the buffered data of the RLC layer is emptied; in this case, if the Bj value of the logical channel is always updated, since the RLC of the logical channel does not transmit data, B thereofjMost likely, a maximum value PBR bsd (bucket size duration) is reached; and at this time B of another logical channel RLC layerjAlthough always updated, BjThe corresponding service data size is subtracted each time a transmission is obtained. Thus, when the data copy function of the radio bearer is reactivated, B's of both RLC' sj(a maximum, a normal update value) will leadSo that the service data sizes of the two RLC layers are different.
For this reason, the embodiments of the present application provide the following method, which can solve the problem. Wherein the following configuration parameter values are the above-mentioned Bj。
Fig. 3 is a schematic flow chart diagram of a wireless communication method 100 according to an embodiment of the present application. The method may optionally be performed by a terminal device. The method 100 includes at least some of the following.
In 110, when 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 value of the first logical channel and the configuration parameter value of the second logical channel are updated based on the same initial value, respectively, where in the first activated state, the first logical channel and the second logical channel transmit the same copy data, and the configuration parameter value is a parameter value configured by the radio resource control, RRC, layer for the logical channel.
Optionally, when a logical channel is established, the initial value of the configuration parameter value is 0, and one logical channel corresponds to one RLC entity.
Alternatively, the first logical channel and the second logical channel may be logical channels for transmitting the duplicated data in a CA scenario, or may be logical channels for transmitting the duplicated data in a DC scenario.
Optionally, in an active state, the PDCP entity transfers data to RLC entities corresponding to the first logical channel and the second logical channel, respectively; and in the deactivated state, the PDCP entity transfers data to the PLC entity corresponding to the first logical channel, but does not transfer data 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 a data radio bearer, or logical channels corresponding to a signaling radio bearer.
In order to facilitate a clearer understanding of the present application, how to make the configuration parameter values of the first logical channel identical to the configuration parameter values of the second logical channel will be described below in connection with several implementations.
In one implementation, in an instance in which it is determined that the data copy function of the radio bearer transitions from the first deactivated state to the first activated state, the configuration parameter value for the second logical channel is set to the configuration parameter value currently existing for the first logical channel, wherein in the first deactivated state, the first logical channel but not the second logical channel is used for transmission.
That is, in the case where the data copy function is transitioned from the first deactivated state to the first activated state, since the first logical channel is always processing data normally, the current configuration parameter value of the first logical channel may be acquired, and the configuration parameter value of the second logical channel may be set as the current configuration parameter value of the first logical channel.
In one implementation, the configuration parameter values of the first and second logical channels are reset to the initial values upon determining that a data copy function of the radio bearer transits from the first deactivated state to the first activated state. Optionally, the initial value is 0.
That is, 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 is different from the configuration parameter value of the second logical channel, the configuration parameter values of the two logical channels may be reset, so that the configuration parameter values of the two logical channels after being reconfigured are the same.
In one implementation, the configuration parameter value of the second logical channel is updated with the configuration parameter value of the first logical channel during the data copy function being in the first deactivated state.
That is, after the data copying function is transitioned from the second activated state to the first deactivated state, during the first deactivated state, since the first logical channel is always processing data normally, the configuration parameter value of the second logical channel may be updated in real time according to the configuration parameter value of the first logical channel, and when the data copying function is transitioned from the first deactivated state to the first activated state, the configuration parameter value of the first logical channel and the configuration parameter value of the second logical channel are always kept consistent.
Optionally, in case of transitioning from a second active state to the first inactive state, suspending updating the configuration parameter value of the second logical channel. And further, in case of a transition from the first deactivated state to the first activated state, an update of the configuration parameter values of the second logical channel may be restarted. It should be appreciated that such an implementation may not be applicable to 110, i.e., it is not necessary to set the configuration parameter values of the first logical channel and the configuration parameter values of the second logical channel to the same values. For example, the values of the configuration parameters of the first and second logical channels may not be changed by the copy data function transitioning from a deactivated state to an activated state.
Optionally, in case of transitioning from the second activated state to the first deactivated state, the configuration parameter value of the second logical channel is set to 0. If the updating is further suspended, the updating of the configuration parameter values of the second logical channel may be restarted in case of a transition from the first deactivated state to the first activated state. It should be appreciated that such an implementation may not be applicable to 110, i.e., it is not necessary to set the configuration parameter values of the first logical channel and the configuration parameter values of the second logical channel to the same values. For example, the values of the configuration parameters of the first and second logical channels may not be changed by the copy data function transitioning from the deactivated state to the activated state.
At 120, a data size to be served for the first logical channel is determined based on the updated configuration parameter value for the first logical channel.
At 130, a data size to be served of the second logical channel is determined based on the updated configuration parameter value of the second logical channel.
It should be understood that 120 and 130 are not performed sequentially.
Therefore, in the embodiment of the present application, when 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 value of the first logical channel and the configuration parameter value of the second logical channel are updated based on the same initial value, so that a problem of transmission resource allocation imbalance caused by too much difference in size of service data to be transmitted in subsequent determination due to different initial values of the configuration parameter values of the first logical channel and the second logical channel can be avoided.
