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 invention.
Fig. 1 shows a network architecture to which an embodiment of the present invention may be applied, and fig. 1 is a system diagram of a data transmission method provided in the embodiment of the present invention. As shown in fig. 1, the network architecture provided by the present embodiment includes a network device and a terminal.
The Network device is a device for accessing a terminal to a wireless Network, and may be a Base Station (BTS) in Global System for Mobile communication (GSM) or Code Division Multiple Access (CDMA), a Base Station (NodeB, NB) in Wideband Code Division Multiple Access (WCDMA), an Evolved Node B (eNB, eNodeB) in Long Term Evolution (LTE), a relay Station or an Access point, or a Network side device (e.g., a Base Station) of an NR System in a future 5G Network or a Network device in a future Evolved Public Land Mobile Network (PLMN), and the like, which are not limited herein.
The terminal may also be referred to as a terminal device, which may be a wireless terminal or a wired terminal, which may be a device providing voice and/or other traffic data connectivity to a user, a handheld device having wireless connection capability, or other processing device connected to a wireless modem. A wireless terminal, which may be a mobile terminal such as a mobile telephone (or "cellular" telephone) and a computer having a mobile terminal, e.g., a portable, pocket, hand-held, computer-included, or vehicle-mounted mobile device, may communicate with one or more core networks via a Radio Access Network (RAN), and may exchange language and/or data with the RAN. For example, devices such as Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs) are used.
Fig. 1 schematically depicts one possible schematic. Wherein the network device 101 and the terminals 102A-102F constitute a communication system. In the communication system, the terminals 102A to 102F may send uplink data or signals to the network device 101, and the network device 101 needs to receive the uplink data or signals sent by the terminals 102A to 102F; the network device 101 may send downlink data or signals to the terminals 102A-102F, and the terminals 102A-102F need to receive the downlink data or signals sent by the network device 101. In addition, terminals 102D-102F may also form a communication system. In the communication system, the network device 101 may transmit downlink data to the terminal 102A, the terminal 102B, the terminal 102E, and the like; the terminal 102E may also transmit downlink data or signals to the terminals 102D and 102F.
With the rapid development of wireless communication technology, various communication products have higher and higher requirements on transmission power, and users have faster and faster requirements on the transmission rate from the terminal to the network equipment. Taking an LTE system as an example, the CA technology and the High Power UE (HPUE) technology based on LTE can effectively improve transmission Power and transmission rate, and the LTE, CA technology and HPUE technology are introduced first, and other communication systems are similar, and this embodiment is not described again here.
Specifically, LTE is a long term evolution of Universal Mobile Telecommunications System (UMTS) technology standard established by The 3rd Generation Partnership Project (3 GPP) organization, wherein LTE has two systems, Time Division Duplex (TDD) and Frequency Division Duplex (FDD).
The TDD-LTE uses the same frequency when sending data and receiving data, and the time of sending uplink and downlink data is staggered, so that uplink and downlink interference is avoided. Optionally, the FDD-LTE uses different frequencies when sending data and receiving data, and there is a duplex interval between the uplink frequency and the downlink frequency.
Further, in LTE, a plurality of frequency bands are obtained by dividing frequency, and different frequency bands may be allocated to different regions, operators, or applied to different scenes, etc. first, the frequency band division of TDD-LTE is described with reference to fig. 1, and fig. 2 is a schematic frequency band diagram of the data transmission method provided in the embodiment of the present invention.
As shown in fig. 2, the frequency bands divided by TDD-LTE include B38, B39, B40, and B41, where B38 is a sub-band of B41, specifically, the frequency range of the B41 frequency band is 2496MHz to 2690MHz, and as shown in fig. 1, each frequency band may be allocated to different operators to implement different functions.
Further, the CA technology may aggregate a plurality of LTE Component Carriers (CCs), thereby implementing expansion of a transmission bandwidth and effectively improving uplink and downlink transmission rates, wherein the terminal device may determine the number of component carriers performing carrier aggregation according to the capability size thereof, which is not limited herein.
The CA technology comprises in-band continuous carrier aggregation and in-band discontinuous carrier aggregation, wherein the in-band continuous carrier aggregation means that two aggregated component carriers are close together, and the in-band discontinuous carrier aggregation means that a partition is arranged between the two aggregated component carriers and is not a continuous component carrier, wherein the in-band continuous carrier aggregation is specifically applied to a data sending mode, and the in-band discontinuous carrier aggregation is specifically applied to a data receiving mode.
Furthermore, the HPUE technology can effectively enhance the signal penetration and increase the signal coverage, so that the signals can be searched more easily in underground parking lots, dense buildings and other scenes.
The prior art is generally based on the following two schemes when implementing CA technology and HPUE technology:
1) non-segmented implementation
That is, the LTE frequency band is not segmented, for example, HPUE technology, in-band continuous carrier aggregation, and in-band discontinuous carrier aggregation are implemented on the full frequency band of B41, however, since the bandwidth of the non-segmented frequency band is wide, the performance of the power amplifier cannot be optimally exerted, so that the transmission power does not reach the standard, and the power requirement of the HUPE technology cannot be met.
2) Realized in three stages
The LTE frequency band is divided into three segments, for example, to obtain a sub-band A, B, C, where a channel interval corresponding to each sub-band may be as follows:
a segment channel interval (a, b)
B-segment channel interval (B +1, c)
C section channel interval (C +1, d)
The a, b, c, and d represent identifiers of channels of the LTE frequency band, where the identifiers of the channels may be channel numbers, preset identifiers of the channels, and the like.
When the CA technology is implemented based on this scheme, if the intra-band continuous carrier aggregation is used, the problem that the channel combination cannot be registered in the span may occur, and if the intra-band discontinuous carrier aggregation is used, the problem that the channel combination cannot be registered may occur. For example, the combination of carrier aggregation is (y, z), where y and z are channel identifiers, and when y and z are not in the same frequency band, a problem of being unable to register occurs.
Therefore, based on the above-mentioned problem of how to implement the method for satisfying the power requirement of the HUPE technology and simultaneously implementing the CA technology, the present invention provides a data transmission method, and the data transmission method provided by the embodiment of the present invention is described in detail below with reference to fig. 2.
Fig. 3 is a first flowchart of a data transmission method according to an embodiment of the present invention. As shown in fig. 3, the method includes:
s301, obtaining a transmission mode corresponding to the current frequency band.
In this embodiment, the TDD-LTE uses the same frequency when transmitting data and receiving data, and therefore needs to first acquire a transmission mode corresponding to a current frequency band, where the transmission mode may be a transmission mode or a reception mode.
Optionally, the current frequency band may be any frequency band in TDD-LTE, for example, may be a B41 frequency band, and may also be a B40 frequency band, and the actual frequency band thereof depends on the frequency band of the current specific application, which is not limited in this embodiment.
S302, if the transmission mode is the sending mode, obtaining a plurality of channel subintervals obtained by dividing the channel interval of the current frequency band, wherein N channel overlaps exist between two adjacent channel subintervals, and N is a positive integer.
In this embodiment, each frequency band corresponds to a respective channel interval, for example, the frequency band range of B41 is 2496MHz to 2690MHz, the corresponding channel interval is (39650,41589), where the number in the channel interval is the identifier of the channel, and the rest frequency bands correspond to respective channel intervals, which is not described herein again.
Specifically, if the transmission mode is the transmission mode, it indicates that data transmission performed in the current frequency band is transmission data, and in implementing the CA technology, in-band continuous carrier aggregation is used, where the problem that channel combination span cannot be registered occurs in the in-band continuous carrier aggregation.
Further, a plurality of channel subintervals obtained after the channel interval of the current frequency band is divided are obtained, wherein N channel overlaps exist between two adjacent channel subintervals, N is a positive integer, and by setting that N channel overlaps exist between two adjacent channel subintervals, each channel combination of in-band continuous carrier aggregation can exist in one channel subinterval, so that the problem that channel combination spanning cannot be registered due to in-band continuous carrier aggregation is solved.
For example, the channel interval of the current frequency band is (a, d), and the 3 channel sub-intervals obtained by dividing the channel interval of the current frequency band are respectively a channel sub-interval 1, a channel sub-interval 2, and a channel sub-interval 3, where the channel sub-interval 1 is (a, b), the channel sub-interval 2 is (b-N, c + N), and the channel sub-interval 3 is (c, d).
Optionally, those skilled in the art may understand that the specific dividing manner of the channel subintervals and the number of the channel subintervals may be selected according to actual requirements, which is not particularly limited herein, as long as there is N channel overlaps between two adjacent channel subintervals, and other implementation manners are similar to those described above, and are not described herein again.
And S303, carrying out data transmission according to the plurality of subchannel intervals.
Further, data transmission is carried out based on a plurality of sub-channel intervals, wherein the performance of the power amplifier can be optimally played by the plurality of sub-channel intervals, the power requirement of the HUPE technology is met, and the CA technology can be realized, so that the problem that the CA combination cannot be registered is solved.
The data transmission method provided by the embodiment of the invention comprises the following steps: acquiring a transmission mode corresponding to a current frequency band; if the transmission mode is a sending mode, acquiring a plurality of channel subintervals obtained after dividing a channel interval of a current frequency band, wherein N channel overlaps exist between two adjacent channel subintervals, and N is a positive integer; and carrying out data transmission according to the plurality of subchannel intervals. When the transmission mode corresponding to the channel of the current frequency band is the transmission mode, the channel subinterval which divides the channel interval into two adjacent channel subintervals and has N overlapped channels is obtained, and then data transmission is carried out based on the multiple channel subintervals, so that the problem that CA combination cannot be registered is avoided, and the use scene of wireless communication is expanded.
On the basis of the foregoing embodiment, the following describes in further detail the data transmission method provided in the embodiment of the present invention with reference to fig. 4, where fig. 4 is a flowchart of a second data transmission method provided in the embodiment of the present invention, and as shown in fig. 4, the method includes:
s401, obtaining a transmission mode corresponding to the current frequency band.
Specifically, the implementation manner of S401 is similar to that of S301, and is not described herein again.
S402, if the transmission mode is the sending mode, acquiring the number of channels corresponding to the carrier aggregation according to the channel combination corresponding to the carrier aggregation.
Further, if the transmission mode is the transmission mode, the channel interval corresponding to the current frequency band needs to be divided into a plurality of channel sub-intervals, and a specific implementation of the division will be described in detail below.
In this embodiment, when carrier aggregation is performed, a channel combination corresponding to carrier aggregation exists, and channels within a channel interval range corresponding to the channel combination are aggregated to obtain an aggregation result, so as to implement bandwidth extension, for example, if the channel combination corresponding to carrier aggregation is (2, 5), channels 2, 3, 4, and 5 need to be aggregated to obtain an aggregated channel, and the channel may be directly used for data transmission.
Specifically, the channel combination corresponding to the carrier aggregation includes a plurality of channels, and the channel number corresponding to the carrier aggregation is obtained according to the channel combination corresponding to the carrier aggregation, where the channel number is a number determined according to an actual carrier aggregation requirement, and this embodiment does not limit this.
S403, determining a channel division index according to the number of channels corresponding to the carrier aggregation; and the number of channels indicated by the channel division index is not less than the number of channels corresponding to the carrier aggregation.
The channel division index is used to indicate the number of channels overlapped between two adjacent channel subintervals, and specifically, to avoid the problem that channel combination span cannot be registered in intra-band continuous carrier aggregation in the transmission mode, it is sufficient to set the number of channels overlapped between two adjacent channel group intervals not less than the number of channels corresponding to carrier aggregation.
Specifically, the multiple carrier aggregations correspond to the channel combinations thereof, so that the number of channels corresponding to the carrier aggregation has multiple values, for example, a maximum value thereof may be selected as a channel division index, or any value not less than the number of channels corresponding to the carrier aggregation may be selected as a channel division index, and the like.
S404, determining the number M of the channel subintervals according to the number of the channels covered by the channel interval of the current frequency band.
Further, the channel interval of the current frequency band includes a plurality of channels, and the number M of the channel subintervals is determined according to the number of the channels covered by the channel interval, for example, the number of the channels included in each channel subinterval may be set to a preset value, so as to determine the number M of the channel subintervals.
Optionally, for example, the number of channel subintervals that is the smallest may be determined according to the number of channels covered by the channel interval and the channel combination corresponding to each carrier aggregation, and the number M of channel subintervals that does not have the problem of unregistering in span combination does not exist.
S405, obtaining M channel subintervals obtained after the channel interval of the current frequency band is divided according to the channel division index and the number of the channel subintervals, wherein M is a positive integer.
Specifically, the number N of channels overlapped between two adjacent subintervals is determined according to the channel division index, and the channel interval is specifically divided into several channel subintervals according to the number of the channel subintervals, so as to obtain M channel subintervals obtained by dividing the channel interval of the current frequency band, wherein N channel overlaps exist between two adjacent channel subintervals.
As described below with reference to a specific example, the channel interval corresponding to the frequency band of B41 in LTE is (39650,41589), and for example, when the channel division index is determined to be 199 according to the number of channels corresponding to carrier aggregation, it indicates that the number of channels corresponding to the channel combination corresponding to each carrier aggregation does not exceed 199.
Further, for example, if it is determined that the number of the channel subintervals M is 3, 3 channel subintervals obtained by dividing the channel interval are obtained, and the specific division may be, for example, the a segment (39650, 40265), the B segment (40065, 40790), and the C segment (40590,41589), so that the problem that channel combination span sections possibly occurring in intra-band continuous carrier aggregation cannot be registered can be correspondingly solved.
Optionally, after obtaining a plurality of channel subintervals obtained by dividing the channel interval of the current frequency band, the method may further debug each channel subinterval to obtain a quiescent current parameter corresponding to each channel subinterval.
Each channel subinterval may correspond to a static current parameter, where the static current parameter is specifically a static current parameter of the power amplifier, and different static current parameters are used for debugging in each channel subinterval, so as to obtain a static current parameter corresponding to each channel subinterval.
And adjusting the power of the channel in each channel subinterval to the target power according to each static current parameter.
Specifically, when the channel interval is not segmented, data transmission is performed only through the quiescent current parameters corresponding to the original channel interval, and the power requirement of the HPUE cannot be met.
And S406, carrying out data transmission according to the plurality of sub-channel intervals.
Specifically, the implementation manner of S406 is similar to that of S303, and is not described here again.
The data transmission method provided by the embodiment of the invention comprises the following steps: and acquiring a transmission mode corresponding to the current frequency band. And if the transmission mode is the sending mode, acquiring the number of channels corresponding to the carrier aggregation according to the channel combination corresponding to the carrier aggregation.

And determining the number M of the channel subintervals according to the number of the channels covered by the channel interval of the current frequency band. And obtaining M channel subintervals obtained after the channel interval of the current frequency band is divided according to the channel division index and the number of the channel subintervals, wherein M is a positive integer. And carrying out data transmission according to the plurality of subchannel intervals. When the transmission mode is the sending mode, the channel division index is determined according to the number of channels corresponding to the carrier aggregation, and then the channel subintervals obtained after the channel interval of the current frequency band is divided are obtained according to the channel division index and the number of the channel subintervals, so that the channel combination corresponding to each carrier aggregation always exists in the same channel subinterval, and the problem of non-registration of the span channel combination is effectively avoided.
On the basis of the foregoing embodiment, optionally, the current frequency band is B41 full frequency band, and the number of channel subintervals M is 3.
On the basis of the foregoing embodiment, optionally, if the transmission mode is the reception mode, data transmission is performed according to the channel interval of the current frequency band.
Specifically, if the current transmission mode is the reception mode, the carrier aggregation is the in-band discontinuous carrier aggregation when the carrier aggregation is performed, and the channel combination cannot be registered in the in-band discontinuous carrier aggregation, so that the data transmission is directly performed by using the channel interval of the current frequency band without segmentation, thereby avoiding the problem that the channel combination possibly cannot be registered in the in-band discontinuous carrier aggregation, and expanding the application scenario of wireless communication.
