Description
Technical Field
The present invention relates to the field of wireless technologies, and in particular, to a method for adjusting a terminal capability level, a network side device, and a terminal.
Background
Currently, two schemes are defined by 3GPP (3 rd Generation Partnership Project, third generation partnership project) for 5G New Radio (NR) networking, namely independent networking (SA) and Non-independent Networking (NSA). The 5G NR independent networking mode requires deployment of a 5G end-to-end brand new network, including a new access network (NR gNB) and a new Core network (NextGen Core), and the 5G independently carries a complete Control-Plane (CP) and a User-Plane (UP), so that the 5G can work independent of an LTE (Long Term Evolution ) network and independently provide communication services for users. In the non-independent networking mode, the 5G needs to rely on the existing LTE network to anchor the control plane on the LTE network (namely LTE bearing control signaling), and the 5G NR and LTE common bearing or 5G NR independent bearing is adopted for the user plane data. Therefore, for the non-independent networking mode, the 5G needs to rely on the existing LTE network to work, and cannot independently provide complete service for users; however, the 5G does not need to deploy a complete end-to-end network, and only needs to deploy an access network to improve the air interface transmission capability, so that the pre-sending requirement of operators on the 5G can be met.
For a 5G NR non-independent networking mode (NSA), a terminal needs to support an LTE-NR dual-connection mode. In the scene, when the traffic of the terminal is smaller or is not in the coverage area of the 5G NR network, the terminal utilizes the LTE network to realize data transmission; when the traffic of the terminal is large or in the coverage area of the 5G NR network, the network can configure an LTE-NR dual-connection transmission mode for the terminal, namely the LTE and the NR need to work simultaneously, the terminal is anchored in the LTE network, and the 5G NR network is used as the supplement of data transmission, so that the data transmission capacity of an air interface is improved.
The terminal supporting the LTE-NR dual-connection mode (i.e. the cross-mode dual-connection mode) is required to support the simultaneous operation of two mode modules, which clearly puts forward higher demands on a computing processing unit and a storage unit of the terminal. Therefore, in the design and implementation process of the terminal, it is considered to implement multiplexing of resources such as radio frequency, baseband physical layer, higher layer and the like between LTE and NR, for example: and a radio frequency access, a processing unit, a storage unit and the like, and realize communication data processing capacity sharing (UE capability sharing) of LTE and NR so as to improve the resource utilization rate of the terminal, thereby avoiding overlarge volume of the terminal and being beneficial to reducing the cost of the terminal.
The UE capability class (UE Category) is directly related to the communication data processing capability, including the amount of data that the UE can process per unit time, the communication buffer space, and the like. In the attachment process of the UE, the Capability (UE Capability) reported by the UE includes UE Category (divided into multiple levels), which reflects the peak rate of uplink/downlink transmission of the terminal, and represents the maximum processing Capability of the physical layer of the terminal. The network acquires the maximum transmission capacity of the terminal, is convenient for reasonably scheduling transmission resources, avoids the situation that the scheduling data volume is too large to exceed the transmission and processing capacity of the terminal, and also avoids the situation that the terminal capacity cannot be fully utilized when a large number of services are required to be transmitted. Therefore, in the 5G NR non-independent networking scenario, the terminal needs to report UE Category when independently operating in the LTE network, and UE Category of each of LTE and NR operating in the LTE-NR dual connectivity mode, so as to indicate the maximum transmission capability of the terminal.
The existing UE Capability level adopts a static reporting indication mechanism, namely, in the attachment process, a terminal reports UE Category in UE Capability, and correspondingly indicates the maximum processing Capability of the UE. The existing network determines the scheduled transmission resource of the terminal according to factors such as channel quality, service demand, network load and the like, and the upper limit of the scheduled transmission resource cannot exceed the terminal communication capacity grade (UE Category) reported by the terminal, namely cannot exceed the maximum transmission processing capacity of the terminal.
However, for the terminal supporting cross-mode dual connection, especially for the terminal adopting processing capacity sharing, the working mechanism has the problems of poor scheduling flexibility and insufficient utilization of the processing resources of the terminal. The reason is that the terminal for realizing cross-system dual-connection by adopting the processing capacity sharing scheme has the capability of flexibly allocating processing resources (such as a calculation processing unit, a cache unit and the like) among different systems to a certain extent according to requirements, but the existing mechanism obviously cannot indicate the condition of flexibly allocating the processing resources. Under the existing mechanism, the terminal adopting the processing capacity sharing is equivalent to that the allocation of the processing resources under two modes is fixed, for example, the transmission processing capacity reported by the terminal in the mode one network is lower than the transmission resource quantity available by the network, that is, the communication capacity reported by the terminal limits the transmission rate of the mode one network, but in practice, the terminal can improve the transmission rate of the mode one network by adjusting the allocation of the processing resources; for another example, the transmission processing capability of the terminal reported in the system one network is higher than the amount of transmission resources available to the network, that is, the transmission rate available to the network is lower, and the processing resources allocated to the system one cannot be fully utilized, but the terminal cannot allocate the part of the processing resources to the system two network for improving the transmission rate of the system two network under the existing mechanism. Therefore, the existing mechanism can influence the flexibility of network scheduling, cannot fully utilize the processing and transmission capacity of the terminal among different systems, optimize the throughput of the terminal and influence the user experience of the terminal.

The technical scheme of the invention aims at the terminal which adopts the processing capacity sharing scheme to realize the cross-mode double connection, and the terminal which adopts the processing capacity sharing scheme to realize the cross-mode double connection is accessed to the network supporting the cross-mode double connection. In the attachment process, the terminal reports two network system (system one and system two) initial UE Category. When the terminal resides in the network, the terminal is anchored in the network of the first mode and establishes a connection path with the first mode. When the network environment, service requirement and the like of the terminal meet the conditions, the network configures a transmission mode of cross-mode dual-connection for the terminal, and the terminal establishes a second connection path with the network of the second mode. The network system I and the network system II respectively determine the distributable resource scheduling conditions according to the channel quality reported by the terminal, the number of supported carriers, the number of transmission layers and other terminal capability information, network load, the service type requirement of the terminal, the data quantity required to be transmitted and other factors; and the network judges the relation between the current communication capacity level of the terminal and the resource scheduling condition, thereby forming resource scheduling indication information and sending the resource scheduling indication information to the terminal. The terminal judges whether to adjust the terminal communication capacity level of two systems according to the resource scheduling indication information sent by the network and by combining the realization and adjustment strategy of the terminal, and feeds back the result to the network. In order to complete the above process, the present invention needs to add a corresponding signaling flow, including a resource scheduling indication information Schedule Information Indication message and a resource scheduling response information Schedule Information Response message, as shown in fig. 3, where the network side device sends the resource scheduling indication information to the terminal, and the terminal sends the resource scheduling response information to the network side device.
Specifically, as shown in fig. 4, the terminal capability level adjustment method of the present embodiment includes the following steps:
and respectively calculating the resource scheduling conditions which can be allocated to a certain terminal by the network type I and the network type II to obtain the terminal communication capacity grade required by the network.
The distributable resource scheduling condition is not limited by the terminal transmission and processing capacity corresponding to the UE Category, namely the scheduling resource quantity which can be allocated to the terminal by the network is judged according to the channel quality reported by the terminal, the supported carrier quantity, the transmission layer number, the modulation order, the Buffer size and other terminal capacity information, the network load, the service type requirement of the terminal, the data quantity required to be transmitted and other factors, so that the terminal communication capacity grade required by the network can be obtained.
And respectively judging the relation between the current communication capacity level of the terminal in each network and the allocable resource scheduling condition by the network system I and the network system II. The current terminal capability level refers to UE Category reported to the network by the terminal, which is the upper limit of the transmission processing capability of the network capable of scheduling the terminal in the conventional scheduling process.
The relationship between the current communication capability level of the terminal and the allocable resource scheduling condition can be divided into two conditions of coincidence and non-coincidence:
the conforming condition, namely the distributed resource scheduling condition is consistent or basically consistent with the current communication capability level of the terminal; non-conforming conditions, including allocable resource scheduling conditions above or below the current communication capability level of the terminal.
More preferably, a threshold value can be preset, and when the absolute value of the difference value between the terminal communication capacity level required by the allocable resource scheduling condition and the current communication capacity level of the terminal is smaller than or equal to the threshold value, the allocable resource scheduling condition is judged to be consistent with the current communication capacity level of the terminal; otherwise, judging that the two images do not match.
And the network side equipment forms resource scheduling indication information based on the judging result.
the network side equipment sends the resource scheduling indication information to the terminal, namely, informs the terminal whether the communication capacity level needs to be updated or not.
More preferably, the first network system and the second network system can judge the relationship between the current communication capacity level of the terminal and the allocable resource scheduling condition in a certain period, and trigger the sending of the resource scheduling indication information periodically or under an event condition.
In the first scheme, a certain smooth window length (T1) is set, the window length comprises judging periods of the relation between the current communication capacity grades of M terminals and the distributable resource scheduling conditions, and the multiple judging results in one window length in the first network mode and the second network mode are respectively subjected to smooth processing, so that the stability of the scheme can be improved, the terminal capacity grades are prevented from being frequently adjusted, and M is an integer larger than 1. Setting a certain period (T2), and sending resource scheduling indication information to the terminal by the network system I and the network system II according to the period, namely whether the current communication capacity level of the terminal accords with or does not accord with the allocatable resource scheduling condition as a result of judging and smoothing the network system I and the network system II, and sending the resource scheduling indication information to the terminal by the network system I and the network system II according to the certain period so as to inform the terminal whether the communication capacity level needs to be updated or not. The parameter values of the smooth window length and the sending period can be flexibly configured according to the requirements.
In the second scheme, a certain smooth window length (T1) is set, the window length comprises judging periods of the relation between the current communication capacity level of M terminals and the distributable resource scheduling condition, the multiple judging results in one window length in the first network mode and the second network mode are respectively subjected to smoothing treatment, and M is an integer larger than 1. Setting corresponding threshold values (X1 and X2 respectively) for the network type one and the network type two respectively, if the smoothing result of the network type one and/or the network type two reaches a trigger condition (for example, the allocable resource scheduling condition is higher or lower than the current communication capability level of the terminal and exceeds the corresponding threshold value), the network type one and the network type two send resource scheduling indication information to the terminal, namely, when the smoothing result of the network type one and/or the network type two is that the current communication capability level of the terminal does not accord with the allocable resource scheduling condition and reaches the trigger condition, the network type one and the network type two send the resource scheduling indication information to the terminal so as to inform the terminal that the updating of the communication capability level is required. The smoothing window length and the threshold value required by the triggering condition can be flexibly configured according to the requirement.
The network transmits a resource scheduling indication information Schedule Information Indication message to the terminal. The resource scheduling indication information may include, but is not limited to: the number of schedulable RBs (scheduling bandwidth), the number of MIMO, the modulation order, the coding rate, the size of the data amount buffer to be transmitted, the size of the code block within a TTI schedulable, the difference between the terminal communication capability level and the current communication capability level of the terminal, which is required for the network schedulable or required UE Category or the assignable resource scheduling situation, etc. The resource scheduling indication information belongs to the per UE message, and thus the Schedule Information Indication message also needs to contain indication information capable of distinguishing different terminals.
and 304, the terminal judges whether to adjust the current communication capability level of the terminal according to the received resource scheduling indication information, and sends a judging result to the network side equipment through the resource scheduling response information.
And the terminal judges whether to adjust the communication capability grade of the terminal in the first mode or the second mode according to the self implementation and adjustment strategy after receiving the resource scheduling indication information, and needs to report the judging result to the network through a resource scheduling response information Schedule Information Response message. The resource scheduling response information sent by the terminal may include, but is not limited to: whether the terminal adjusts the communication capability level of the first system and the second system, if so, the terminal also needs to comprise a corresponding communication capability level adjustment value or a difference value between the communication capability level adjustment value and a previous communication capability level reporting value, and the like.

In the attaching process, the terminal reports initial UE Category in the first and second network modes, and the transmission and processing capacities of the corresponding terminals are 600Mbps at maximum, so that the terminals are required to support 8MIMO and DL 64QAM (first mode); the maximum transmission and processing capacity of the terminal is 2Gbps, and the terminal is required to support 4MIMO and DL 256QAM (second system). When the network environment, service requirement and the like of the terminal meet the conditions, the network configures a transmission mode of cross-mode dual-connection for the terminal, and the network mode I and the network mode II perform normal scheduling on the terminal.
Meanwhile, periodically calculating the resource scheduling conditions which can be allocated to the terminal according to the first network mode and the second network mode respectively to obtain the terminal communication capacity level required by the network; the result of smoothing a plurality of periods is that the transmission and processing capacity of the terminal required by the system-one allocable resource is 150Mbps at maximum, and the terminal is required to support 2MIMO and DL 64QAM; the maximum transmission and processing capacity of the terminal required by the system II allocable resources is 4Gbps, and the terminal is required to support 8MIMO and DL 256QAM. The first network system and the second network system form resource scheduling indication information and send the resource scheduling indication information to the terminal.

When the network environment, service requirement and the like of the terminal meet the conditions, the network configures a transmission mode of cross-mode dual-connection for the terminal, and the network mode I and the network mode II perform normal scheduling on the terminal.
Meanwhile, periodically calculating the resource scheduling conditions which can be allocated to the terminal according to the first network mode and the second network mode respectively to obtain the terminal communication capacity level required by the network; the result of smoothing in multiple periods is that the transmission and processing capacity of the terminal required by the system-one allocable resource is 600Mbps at maximum, and the terminal is required to support 8MIMO and DL 64QAM; the maximum transmission and processing capacity of the terminal required by the system II allocable resources is 4Gbps, and the terminal is required to support 8MIMO and DL 256QAM. The first network system and the second network system form resource scheduling indication information and send the resource scheduling indication information to the terminal.
The terminal combines the self-adjusting strategy according to the resource scheduling indication information sent by the first network mode and the second network mode, for example, the terminal capacity grade required by the network resource scheduling corresponding to one mode X in the cross-mode dual-connection is higher than the current terminal capacity grade of the mode; and if the terminal capacity level required by the network resource scheduling corresponding to the other system Y is equal to the current terminal capacity level, judging that the terminal capacity levels of the two systems are not adjusted.
