Fig. 2 is a flow diagram of a link establishment method in one embodiment. The link establishment method in this embodiment is described by taking the terminal device in fig. 1 as an example. As shown in fig. 2, the above method package:
s101, a baseband processor receives indication information sent by a base station; the indication information is used for indicating the terminal equipment to establish the first link.
The baseband processor may be a processor in a digital baseband system. The digital baseband system may be a system for performing a signal modulation and demodulation function in a terminal device. The digital baseband system may include a plurality of baseband modules, where the baseband module may be an uplink digital channel or a downlink digital channel; the uplink digital channel can send digital baseband signals to the radio frequency module, and the digital baseband signals are processed by the radio frequency module and then sent to the network equipment through the antenna. The downlink digital channel can receive downlink data sent by the radio frequency module and demodulate the downlink data.
The baseband processor may demodulate the downlink data sent by the network device to obtain the indication information sent by the network device. The indication Information may be sent through a Downlink Control Information (DCI).
The indication information may be used to instruct the terminal device to establish the first link. The first link may be an uplink or a downlink, and is not limited herein. The first link may include one link channel or a plurality of link channels, which is not limited herein. The first link may support a 4G/5G Dual Connectivity (EUTRA-NR Dual Connectivity, abbreviated as ENDC), a 5G/5G Dual Connectivity (NR-NR Dual Connectivity, abbreviated as NNDC), and a Supplementary Uplink (SUL) combined communication connection; the communication scenario supported by the first link is not limited herein. Optionally, the first link may be used to implement Carrier Aggregation (CA).
After registering a network, the terminal device may receive indication information sent by the network device to establish a first link; alternatively, the terminal device may receive the indication information to switch the current link to the first link when the link connection with the network device is already established. That is, the indication information may be used to instruct the terminal device to newly establish the first link, or to instruct the terminal device to switch the current link to the first link. The network device may determine whether to send the indication information according to a service requirement of the terminal device, so as to indicate the terminal device to perform link switching.
The indication information may include carrier information of a first link to be established, a link identifier of the first link, a communication scenario identifier corresponding to the first link, and a communication frequency band identifier corresponding to the first link, and the content in the indication information is not limited herein. The carrier information of the first link may include a center frequency point, a link bandwidth, a subcarrier interval, and the like corresponding to the first link. Taking the first link for uplink carrier aggregation in the NR system as an example, the carrier aggregation may support multiple scenarios, as shown in the following table:
scene numbering Scene description
Scene A N78 single carrier single stream
Scene B N78 single carrier dual stream
Scene C N3 single carrier single stream
Scene D N78 Single stream + N3 Single stream
Wherein, the N78 is at a frequency band of 3.3GHz-3.8GHz, and the N3 is at a frequency band of 1710MHz-1785 MHz. N78 has a large frequency bandwidth and can meet the requirement of high throughput; the above N3 supports FDD carriers, which can meet the requirement of low latency. The uplink corresponding to the scenario a and the scenario C may include 1 link channel; the uplink corresponding to the scenarios B and D may include 2 link channels. Taking the uplink in the scenario B as an example, the indication information may include a communication scenario identifier, that is, the scenario B, and may also include a communication frequency band identifier, for example, N78.
S102, the baseband processor performs parameter configuration on the link resource module to establish a first link; the link resource module is a module related to establishing the first link in the terminal equipment.
After receiving the indication information, the baseband processor in the terminal device may configure the parameter of the link resource module based on the indication information. The link resource module may include a baseband module, a radio frequency module, a local oscillator module, a power amplifier module, an antenna switch module, and an antenna module.
When the first link completes uplink data transmission or downlink data transmission, the modules to be used may include a baseband module, a radio frequency module, a local oscillator module, a power amplifier module, an antenna switch module, and an antenna module. Wherein, above-mentioned radio frequency module can accomplish signal frequency conversion, and above-mentioned local oscillator module can provide local oscillator signal to radio frequency module, and above-mentioned power amplifier module can amplify the signal, and above-mentioned antenna switch module can be through being connected of on-off control radio frequency module and antenna, and above-mentioned antenna module is used for received signal or sends the signal of power amplifier output to network equipment. Modules in the terminal device may be capable of supporting multiple link paths. Taking the uplink hardware architecture diagram shown in fig. 3 as an example, the digital baseband system in the terminal device may include 3 uplink digital channels, corresponding to 3 baseband modules; the radio frequency analog system in the terminal equipment comprises 3 radio frequency modules and 2 local oscillator modules; the front-end antenna system in the uplink hardware architecture comprises 3 power amplifier modules, 2 antenna switch modules and 2 antenna modules.
The link resource module may be a module in the terminal device related to establishing the first link. The module related to establishing the first link may include a module that needs to be used to establish the first link, and may also include a module that needs to release resources after establishing the first link. Taking the uplink hardware architecture diagram in fig. 3 as an example, if the indication information is used to establish a new first link, and the first link is an N78 single-stream link, the link resource module may include a baseband module, an N78 matched rf module, an N78 matched power amplifier module, a local oscillator module, an antenna switch module, and an antenna module. If the indication information is used to switch the current link to the first link, taking the current link as an N3 single-stream link and the first link as an N78 single-stream link as an example, the link resource modules may include 2 baseband modules, one radio frequency module corresponding to N78, 1 radio frequency module corresponding to N3, a power amplifier module corresponding to N78, a power amplifier module corresponding to N3, 2 local oscillation modules, 2 antenna switch modules, and 2 antenna modules.
The baseband processor can perform parameter configuration on the link resource module. The baseband processor can control each link resource module respectively. The configuration parameters corresponding to different types of link resource modules may be different. For example, the configuration parameters of the baseband module may include a signal frequency, a carrier bandwidth, a carrier interval, and the like output by the baseband module; the configuration parameters of the radio frequency module may include an intermediate frequency, a link attenuation, etc., the configuration parameters of the local oscillator module may include a local oscillator frequency, etc., and the configuration parameters of the power amplifier module may include an attenuation, a static parameter, a temperature compensation coefficient, etc. In addition, the configuration parameters of the link resource module may further include a connection relationship between the modules, for example, a baseband module used by the first link is connected to which radio frequency module, a radio frequency module used by the first link is connected to which local oscillator module, and a conducting direction of the antenna switch module, that is, which power amplifier module is conducted by the antenna switch module with the antenna module.
After the baseband processor in the terminal device performs parameter configuration on the link resource module, the first link can complete data transmission in the corresponding working frequency band.
The baseband processor may include one processing unit or may include a plurality of processing units. In the case that the baseband processor includes one processing unit, the steps of receiving the indication information, completing parameter configuration, and the like may be completed by the processing unit in the link establishment process. Optionally, the baseband processor may include 3 processing units, which are a Central Link Control Unit (CLCU), a Resource management Unit (CLRU), and a drive configuration Unit (CLDU). The CLCU is mainly used for collecting applications for the link resource module, and comprises receiving indication information sent by the network equipment and scheduling the CLDU and the CLRU according to the indication information. The CLDU may be used to configure parameters of each link resource block. The CLRU is configured to manage the link resource module and the configuration parameter corresponding to the link resource module.
In the link establishing method, a baseband processor in the terminal equipment receives indication information sent by the network equipment; based on the indication information, the baseband processor performs parameter configuration on the link resource module to establish a first link; the link resource module is a module related to establishing a first link in the terminal device. The steps of receiving indication information sent by the network equipment to establish the first link, performing parameter configuration on the link resource module and the like in the terminal equipment are all completed by the baseband processor, so that the establishing process of the first link in the application can avoid signaling interaction between a digital baseband system and systems where other link resource modules are located, and the establishing time delay of the first link is reduced; furthermore, the terminal device completes parameter configuration of other link resource modules through the baseband module, so that the link resource modules such as the radio frequency module and the like can be simplified to a pure hardware circuit, the complexity of the circuit structure is reduced, the sizes of the other link resource modules are reduced, and the system integration level is improved.
Fig. 4 is a schematic flowchart of a link establishment method in an embodiment, where the embodiment relates to a process of switching a terminal device from a current link to a first link, and on the basis of the embodiment, as shown in fig. 4, the step S102 includes:
s201, the baseband processor acquires resource configuration parameters related to the first link.
The indication information is used for indicating the terminal equipment to switch from the current link to the first link. Taking NR system as an example, in order to improve uplink throughput and reduce system delay, the terminal device may perform uplink handover within a capability range. The terminal device may receive the DCI message sent by the network device, and obtain the indication information by parsing the DCI message. The indication information may further include a time requirement for link switching, for example, the network device may require the terminal device to complete link switching within the time period T. Taking the handover diagram in fig. 5 as an example, the current link of the terminal device may be an N3 single-stream link plus an N78 double-stream link; the terminal equipment can receive the DCI message at slot1, analyze the DCI message to obtain indication information and indicate the terminal equipment to switch from the current link to the N78 double-flow link; the shaded portion in the figure may be a time period T of link switching, and the terminal device may start to perform link switching at slot3, and may start to perform uplink transmission through an N78 dual-stream link at slot 4.
The time period of the link switching may be 35 microseconds or 140 microseconds. And the uplink data sent by the terminal equipment in the time period T is invalid data. The time period T may be a parameter reported by the terminal device to the base station according to the system capability of the terminal device, and the shorter the time period T is, the shorter the corresponding uplink pair handover delay is.
The resource configuration parameter refers to a configuration parameter corresponding to a first resource module used by the first link in the first link. After receiving the indication information, the baseband processor calculates which resource modules are related link resource modules in the process of switching to the first link, and further determines the configuration parameters corresponding to the link resource modules. Optionally, after receiving the indication information, the baseband processor may query the identifier of the first resource module in a preset resource configuration relationship; and then, inquiring parameters matched with the identification in a preset configuration parameter list to obtain resource configuration parameters.
Alternatively, the baseband processor may also obtain a pre-configuration parameter, where the pre-configuration parameter may be a link resource module related to the first link and determined in advance before the indication information is received, and a configuration parameter of the link resource module. Optionally, the baseband processor may query, before receiving the indication information, an identifier of the first resource module in a preset resource configuration relationship; and then inquiring parameters matched with the identifier of the first resource module in a preset configuration parameter list to generate pre-configuration parameters. The terminal device may call the pre-configured parameter in a preset storage area, and determine the pre-configured parameter as a resource configuration parameter. The manner of acquiring the resource configuration parameters is not limited herein.
In one implementation, the baseband processor may determine whether the current link supports link switching according to the terminal device capability; and if so, executing the step of generating the pre-configuration parameters. And if the current link of the terminal equipment does not support the link switching, the step of generating the pre-configuration parameters is not executed.
The resource configuration relationship may include module identifications required by different links. Taking the links corresponding to each carrier aggregation scenario shown in the above table as an example, the resource configuration relationship may be as follows:
Figure BDA0003408600600000101
taking the case that the terminal device switches from the uplink of the scene D to the uplink of the scene B, the link resource modules involved in the link switching of the terminal device may include a baseband module 0-2, a radio frequency module 0-2, a local oscillator module 0-1, a power amplifier module 0-2, an antenna switch module 0-1, and an antenna module 0-1. The first resource module used by the first link can comprise a baseband module 1-2, radio frequency modules 1-2, a local oscillator module 1, power amplifier modules 1-2, antenna switch modules 0-1 and antenna modules 0-1.
The terminal device can calculate which modules are the first resource modules according to the control instruction of the CLCU through the CLRU in the baseband module, and further determine the configuration parameters of each first resource module according to a preset configuration parameter list. The configuration parameter list includes parameters corresponding to the resource modules in different links.
It should be noted that the current link may have the capability of being switched to a different link, that is, the current link may be switched to a different link. For example, the current link is a link corresponding to the scene D, and the current link may be switched to a link corresponding to the scene D or switched to a link corresponding to the scene C.
The baseband processor, in determining the preconfigured parameters, may determine the preconfigured parameters corresponding to when the current link is switched to a different link. The CLRU may query a resource module used by each candidate handover link in a resource configuration relationship stored in a Non-Volatile Random Access Memory (NVRAM), query a pre-configured parameter corresponding to each candidate handover link, mark the candidate handover link, and store each pre-configured parameter in a semi-static manner. For example, if the current link is an N3 single stream link plus an N78 single stream link, the resource module corresponding to the N3 frequency band in the current link may be switched to the N78 frequency band; the baseband processor may query the resource configuration corresponding to N78 based on the resource configuration relationship under the current link, and store in the following table manner:
Figure BDA0003408600600000111
after receiving the indication information, the CLCU in the baseband processor may send a scheduling instruction to the CLRU according to the corresponding first link in the indication information, so that the CLRU may send the preconfigured parameter corresponding to the first link to the CLDU; the CLDU may write the preconfigured parameter corresponding to the first link in a register form into the DRAM, and after receiving the scheduling instruction of the CLCU, perform parameter configuration on the first resource module using the preconfigured parameter.
S202, the baseband processor sets parameters of the first resource module by adopting the resource configuration parameters; the first resource module is a module used in the first link.
The baseband processor may perform parameter setting on each first resource module by using the resource configuration parameters, so that the set first resource module may perform data transmission in the first link.
The baseband processor can carry out parameter setting on each first resource module according to a random sequence; the parameter setting may also be performed according to the preset sequence of each first resource module, which is not limited herein.
S203, the baseband processor releases resources of the second resource module; the second resource module is a module used by the current link and not used in the first link.
After the parameter setting of the first resource module is completed, the baseband processor may release resources for a second resource module that is used by the current link and is not used in the first link.
In the link establishment method, the baseband processor completes the establishment of the first link by performing parameter configuration on the first resource module and performing resource release on the second resource module; further, under the condition that the baseband processor performs parameter configuration on the first resource module through the preconfigured parameters, before the terminal device receives the indication information, the baseband processor may complete calculation of the first resource module in the switching process and complete parameter acquisition of the first resource module, so that after receiving the indication information, the baseband processor may directly perform parameter configuration on the first resource module by using the preconfigured parameters, thereby further reducing link switching delay; furthermore, the baseband processor manages the resource modules in a unified manner through the resource configuration relationship and the configuration parameter list, so that signaling interaction in the link establishment process can be reduced, the link establishment expandability can be improved, and when the terminal device supports links in other scenes, only the resource configuration relationship needs to be optimized.
In one embodiment, the resource configuration parameters include a first parameter of a shared resource module and a second parameter of a non-shared resource module; the shared resource module is a module used by both the first link and the current link; the non-shared resource module is a module used by the first link and not used by the current link.
The baseband processor may query, in a preset resource configuration relationship, an identifier of a first resource module used by the first link, and query, in the preset resource configuration relationship, an identifier of a link resource module used by the current link; further, the identifier of the link resource module used by the current link is compared with the identifier of the first resource module, so as to determine a shared resource module and a non-shared resource module in the first resource module.
A single stream link in a first frequency band (e.g., N3) and a single stream link in a second frequency band (e.g., N78) with a current link; the first link includes a dual-flow link of the second frequency band (e.g., N78), for example, and referring to the uplink hardware architecture in fig. 3, the above link switching process may be as shown in fig. 6. In fig. 6, the modules are connected by solid lines to form the current link; the modules are connected through a dotted line to form a switched first link. As shown in fig. 6, the resource sharing modules of the current link and the first link may include a digital baseband module 2, a radio frequency module 2, a power amplifier module 2, an antenna switch module 0, an antenna switch module 1, an antenna module 1, and an antenna module 0. The non-shared resource module may include a digital baseband module 1, a radio frequency module 1, and a power amplifier module 1.
The baseband processor may determine a first parameter used by the shared module and a second parameter used by the unshared module according to a preset configuration parameter list. Further, the baseband module may configure the parameter of the non-shared resource module as a second parameter; then, the current parameter of the shared resource module is modified to the first parameter.
Fig. 7 is a flowchart illustrating a link establishing method in an embodiment, where this embodiment relates to a process of a terminal device newly establishing a first link, and on the basis of the foregoing embodiment, as shown in fig. 7, the foregoing S102 includes:
s301, the baseband processor queries the identifier of the first resource module used by the first link in a preset resource configuration relationship.
S302, parameters matched with the identification of the first resource module are inquired in a preset configuration parameter list, and resource configuration parameters are obtained.
S303, configuring the first link resource module by adopting the resource configuration parameters.
The above procedure for newly building the first link is different from the procedure for switching from the current link to the first link in that after receiving the indication information, the baseband processor in the terminal device directly obtains the resource configuration parameter corresponding to the first link through the resource configuration relationship and the configuration parameter list, instead of obtaining the resource configuration parameter through the pre-configuration parameter. In addition, aiming at the condition of newly building the first link, the link resource module associated with the first link is the first resource module used by the first link, but does not include a module unused by the first link; therefore, the baseband processor does not need to release resources for modules not used by the first link.
In the link establishing method, the baseband processor completes parameter configuration of the first resource module in the process of newly establishing the first link by the terminal equipment, so that signaling interaction between a digital baseband system and a system where other link resource modules are located is avoided, and the establishing time delay of the first link is reduced.
In one embodiment, as shown in fig. 8, the link establishment method includes:
s401, the network equipment sends indication information for establishing the first frequency band single flow link to the terminal equipment.
S402, a baseband processor in the terminal device queries an identifier of a first resource module used by the first frequency band single-flow link in a preset resource configuration relationship.
S403, the baseband processor in the terminal device queries, in a preset configuration parameter list, a parameter matching an identifier of a first resource module used by the first frequency band single-stream link, and obtains a resource configuration parameter corresponding to the first frequency band single-stream link.
S404, a baseband processor in the terminal device configures a first link resource module used by the first frequency band single-stream link by using a resource configuration parameter corresponding to the first frequency band single-stream link.
Taking the NR system as an example, when the terminal device accesses the N3 cell, the network device may notify the terminal device through a DCI message to establish an N3 single-flow link, and require that the link establishment be completed after the TimeA.
The CLCU in the baseband processing can schedule CLRU to inquire link resources according to carrier information such as N3 central frequency point, bandwidth, subcarrier interval and the like configured by the network equipment. The CLRU finds the N3 single carrier link resource information from the resource allocation relationship stored in the NVRAM according to the carrier information, and then stores the resource information in the allocated memory space of the system. The CLRU will mark the first resource module used by the N3 link with the link number, as shown in the table below, and return the link number to the CLCU.
Figure BDA0003408600600000151
Further, the CLRU may send a parameter query instruction to the CLDU to instruct the CLDU to query the N3 link for the configuration parameters of the resource modules used by the link. The CLDU queries a parameter matching the identifier of the first resource module used by the first frequency band single-stream link from the configuration parameter list according to the serial number of each module, and then formats each configuration parameter and stores the configuration parameter in the DRAM in the form of a register. The CLCU may send a parameter configuration indication to the CLDU based on the TimeA indicated by the network device and the link number of the N3 link. The CLDU can configure the configuration parameters already stored in the DRAM to the respective resource modules. The CLDU may complete parameter configuration before the Times A-D0-TD. Where TD is the transmission delay of the digital interface, and D0 is greater than the link switching period T. In the above-mentioned process of establishing the N3 link, the interaction between the processing units in the baseband processor can be seen in fig. 9.
S405, the network equipment sends indication information for establishing the second frequency band single-flow link to the terminal equipment.
S406, the baseband processor in the terminal device queries, in a preset resource configuration relationship, an identifier of the first resource module used by the second frequency band single-stream link.
S407, the baseband processor in the terminal device queries, in a preset configuration parameter list, a parameter matching an identifier of the first resource module used by the second frequency band single-stream link, to obtain a resource configuration parameter corresponding to the second frequency band single-stream link.
And S408, the baseband processor in the terminal device configures the first link resource module used by the second frequency band single-flow link by using the resource configuration parameter corresponding to the second frequency band single-flow link.
Continuing with the NR system as an example, when the terminal device accesses the N78 cell, the terminal device may notify the terminal device through a DCI message to establish an N78 single-stream link, and form uplink carrier aggregation with the N3 single-stream link. The network device may notify the terminal device that link establishment is complete after TimeB.
Similar to the above-mentioned process of establishing the N78 single-flow link, as shown in fig. 9, the CLDU may complete the parameter configuration of the N78 single-flow link before the times B-D1-TD.
After S405, the method further includes:
s409, a baseband processor in the terminal equipment inquires the identifier of the first resource module used by the second frequency band double-current link in a preset resource configuration relationship.
S410, a baseband processor in the terminal equipment inquires a parameter matched with the identifier of the first resource module in a preset configuration parameter list to generate a pre-configuration parameter.
Continuing with the NR system as an example, after the CLCU receives the indication information to establish the N78 single stream link, it can determine whether the combination of the N3 single stream link and the N78 single stream link supports link switching. If not, the baseband processor can complete the establishment of the N78 single-flow link according to the steps; if supported, the indication that the switched N78 dual stream link may use the resource modules used by the N3 single stream link. The CLRU needs to inquire the identification of a first resource module which needs to be used by the N78 dual-stream link in the resource configuration relationship, and sends the link label to the N78 dual-stream link to the CLDU. The CLDU may determine the shared resource module of the current link and the switched N78 dual-stream link based on the link identifier, and store the configuration parameters of the shared resource module in the N78 dual-stream link in the DRAM in the form of a register to form preconfigured parameters.
S411, the network device sends indication information of the double-current link switched to the second frequency band to the terminal device.
S412, the baseband processor of the terminal equipment obtains a pre-configuration parameter; the pre-configuration parameters comprise a second parameter corresponding to the non-shared resource module and a first parameter corresponding to the shared resource module.
S413, the baseband processor of the terminal device configures the parameter of the non-shared resource module as a second parameter.
And S414, the baseband processor of the terminal equipment modifies the current parameter of the shared resource module into the first parameter.
S415, the baseband processor of the terminal device releases the resource of the second resource module.
Continuing with the NR system as an example, after receiving the DCI, the baseband processor in the terminal device obtains, through parsing, indication information for switching to the N78 dual-flow link, where the indication information requires the terminal device to switch from Time C to the N78 dual-flow link for data transmission.
Under the condition that a baseband processor in the terminal device obtains the pre-configuration parameters in advance, the CLCU only needs to schedule the CLDU for parameter configuration, and the CLDU can complete the parameter configuration of the non-shared resource module used by the N78 dual-flow link, the parameter configuration of the shared resource module used by the N78 dual-flow link, and the resource release of the second resource module used by the N3 in sequence based on the pre-configuration parameters stored in the DRAM. As shown in fig. 9, CLDU may complete parameter configuration for an N78 dual stream link before TimeC-D1-TD. The CLDU can complete the parameter configuration of the non-shared resource module in the N78 dual-stream link before Time C-T-TD (T is the minimum link switching period supported by the terminal report), so that the data transmission of the N3 single-stream link is not affected. Then before Time C-D2-TD (D2< T), completing parameter configuration of a shared resource module of the N78 double-flow link, and releasing resources of a second resource module used by the N3 single-flow link; on this basis, the N78 dual stream link may transmit data after Time C and stop transmitting data on the N3 single stream link.
The link establishment method meets the time requirement of the link switching period of the terminal equipment, can reserve more time for data transmission, and improves the throughput rate of the terminal equipment. For example, in the conventional method, 140 microseconds are needed to switch the N3 single-stream link plus the N78 dual-stream link to the N78 dual-stream link, but by adopting the method in this embodiment, the link switching time can be compressed to 35 microseconds, and the link switching period is shortened by 75%. In addition, link establishment is completed by the multiple processing units in the baseband processor, and link establishment tasks can be processed in parallel, so that link switching efficiency is further improved, and link switching time delay is reduced.
It should be understood that although the various steps in the flow charts of fig. 2-9 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise.
