Description

Uplink transmission method and device

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an uplink transmission method and apparatus.

Background

With the evolution of the technology and the increase of data services, in the subsequent release of the Long term evolution-advanced (LTE-a) system, the following Carrier Aggregation (CA) scenario may exist:

the carrier (or cell) for the terminal to perform CA uses different frequency band (band) resources, i.e., Inter-band CA. The frame structures used by the terminal in different Frequency bands may be the same or different, for example, the terminal uses a Frequency Division Duplex (FDD) frame structure on each carrier in different Frequency bands, or the terminal uses a Time Division Duplex (TDD) frame structure on each carrier in different Frequency bands (where TDD uplink/downlink configurations used by each carrier in different Frequency bands may be the same or different), or the terminal uses an FDD frame structure on each carrier in one Frequency band and a TDD frame structure on each carrier in another Frequency band.

The terminal has the capability of receiving multiple carriers at the same time in the downlink, namely, the terminal can receive downlink data from the service base station of the frequency band at different aggregated frequency bands at the same time in each downlink subframe, and the different frequency bands are served by different base stations. However, in consideration of the complexity and cost of radio frequency, the terminal only supports a single-frequency-band transmission capability in uplink, that is, only supports transmitting uplink signals on one frequency band to the base station serving the frequency band in each uplink subframe.

For a terminal working in an Inter-band CA scenario, Uplink transmission may exist on multiple Uplink carriers belonging to different frequency bands, where the Uplink transmission may include a Physical Uplink Control Channel (PUCCH), a Physical Uplink Shared Channel (PUSCH), a Sounding Reference Signal (SRS), and the like. However, the terminal only supports a single-frequency-band transmitting capability in uplink, and when uplink transmission needs to be performed on uplink carriers of different frequency bands, no corresponding transmission scheme exists.

Detailed Description

According to the technical scheme provided by the embodiment of the invention, the uplink sub-frame in the shared uplink sub-frame set is distributed for each frequency band of carrier aggregation, so that the uplink data is only sent on one frequency band in one uplink sub-frame, the uplink data is sent to different network equipment in different frequency bands in a time division multiplexing mode, and the uplink transmission of the terminal equipment with the single-frequency-band sending capability is realized in an Inter-band CA scene. In the embodiment of the present invention, carrier aggregation refers to: in a downlink subframe, a terminal can receive downlink data on multiple frequency bands simultaneously, and in an uplink subframe, the terminal can only transmit uplink data on one frequency band.

The technical solutions provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Fig. 1 is a flowchart of a side method of a terminal device according to an embodiment of the present invention, which is implemented as follows:

step 100, determining an uplink subframe occupied by each frequency band of carrier aggregation in a shared uplink subframe set according to a distribution mode predetermined with a network device or configuration information sent by the network device.

The frequency band of the carrier aggregation of the terminal equipment at least comprises two frequency bands, and uplink subframes occupied by each frequency band are different from each other.

The shared uplink subframe set is a set of uplink subframes with the same subframe number in a radio frame in a frame structure used on each frequency band.

For example, the terminal device carrier aggregates band 1 and band 2. An FDD frame structure is used in frequency band 1 and a TDD frame structure with uplink/downlink configuration 0 is used in frequency band 2. In a radio frame, all subframes with subframe numbers of 0-9 in an FDD frame structure are uplink subframes, and subframes with subframe numbers of 2, 3, 4, 7, 8 and 9 in a radio frame in a TDD frame structure with uplink/downlink configuration 0 are uplink subframes, so the uplink subframe set shared by a frequency band 1 and a frequency band 2 is { subframe 2, subframe 3, subframe 4, subframe 7, subframe 8 and subframe 9 }. Taking subframe 2 as an example, subframe number 2 is referred to.

And step 110, in each uplink subframe in the shared uplink subframe set, transmitting uplink data on the frequency band occupying the uplink subframe.

In the embodiment of the present invention, there are various implementation manners of determining, according to configuration information sent by a network device, an uplink subframe occupied by each frequency band of carrier aggregation in a shared uplink subframe set, which are listed below.

The first implementation manner of allocating the uplink subframe to each frequency band according to the configuration information is as follows:

receiving a high-level signaling sent by network equipment, wherein the high-level signaling carries configuration information in a bitmap (bitmap) form; and determining the uplink subframe occupied by each frequency band in the shared uplink subframe set according to the value of the A bit and the uplink subframe corresponding to each A bit in the configuration information.

In the configuration information, each a bit corresponds to an uplink subframe in a radio frame or an uplink subframe in the shared uplink subframe set, a value of the a bit indicates a frequency band occupying the uplink subframe, and a = [ log ], [₂B]B is the number of aggregated frequency segments (i.e., the number of carrier aggregated frequency segments);

the correspondence between each a bit and the uplink subframe is predetermined.

For example, assuming that there are a frequency band 1 and a frequency band 2, when a =1, the correspondence between the value of the a bit and the frequency band occupying the uplink subframe is shown in table 1.

Table 1: corresponding relation between A bit information corresponding to each uplink subframe and indication frequency band

Based on the first implementation manner, assuming that the terminal device aggregates 2 frequency bands, one frequency band is deployed as a Macro cell (Macro cell), one frequency band is deployed as a small cell (small cell), and both the Macro cell and the small cell use an FDD frame structure, the shared uplink subframe set is all uplink subframes in one radio frame, the subframe number is from 0 to 9, a =1, that is, each 1-bit information corresponds to one uplink subframe, different states of the 1-bit information respectively indicate which frequency band the uplink subframe is occupied, 10 bits of configuration information are required in total, for example, assuming that a state "0" of 1 bit indicates that the subframe is occupied by the Macro cell, and a state "1" indicates that the subframe is occupied by the small cell, when the state of the configuration information is "0101010101", it indicates that a subframe with an even number is occupied by the Macro cell, and a subframe with an odd number is occupied by the small cell, or, when the state of the configuration information is "0000011111", it indicates that the first 5 subframes are occupied by the Macro cells and the last 5 subframes are occupied by the small cells, or, when the state of the configuration information is "0111101111", it indicates that the 1 st and 6 th subframes are occupied by the Macro cells and the remaining subframes are occupied by the small cells.

Based on the first implementation manner, it is assumed that the terminal device aggregates 2 frequency bands, a frequency band 1 (for example, a frequency band deployed as a small cell) uses an FDD frame structure, a frequency band 2 (for example, a frequency band deployed as a Macro cell) uses a TDD frame structure and TDD uplink/downlink configuration 1, the shared uplink subframe set is an uplink subframe with subframe numbers of 2, 3, 7, and 8 in a radio frame, a =1, it is assumed that a 1-bit state "0" indicates that the subframe is occupied by the frequency band 2, and a state "1" indicates that the subframe is occupied by the frequency band 1, which is a first configuration information manner: 10-bit configuration information may be always used, and each 1-bit information corresponds to one subframe in one radio frame, for example, when the status of the configuration information is "1101110111", it indicates that uplink subframes with subframe numbers 2 and 7 in the shared uplink subframe set are occupied by frequency band 2, and uplink subframes with subframe numbers 3 and 8 are occupied by frequency band 1, and in addition, uplink subframes which are not shared in the frame structure, such as uplink subframes with subframe numbers 0, 1, 4, 5, 6 and 9, may also be used on frequency band 1; in a second configuration information manner, the configuration information only includes indication information of each bit corresponding to the shared uplink subframe, that is, configuration information of 4 bits is required in common, for example, when the state of the configuration information is "0101", it indicates that the first and third uplink subframes (i.e., uplink subframes with subframe numbers of 2 and 7) in the shared uplink subframe set are occupied by the frequency band 2, and the second and fourth uplink subframes (i.e., uplink subframes with subframe numbers of 3 and 8) are occupied by the frequency band 1; the third configuration information mode: when the frequency band 1 and the frequency band 2 both use the TDD frame structure, the configuration information may include all uplink subframes in one radio frame, where each 1-bit information in the configuration information corresponds to one uplink subframe in one radio frame, and it is assumed that the frequency band 1 uses TDD uplink/downlink configuration 0, and the frequency band 2 uses TDD uplink/downlink configuration 1, and 6-bit configuration information is required in total, for example, when the state of the configuration information is "110110", it indicates that the uplink subframes with the subframe numbers of 4 and 9 are occupied by macro cells, and the uplink subframes with the subframe numbers of 2, 3, 7, and 8 are occupied by small cells.

And a second implementation mode of allocating uplink subframes for each frequency band according to the configuration information:

receiving a higher layer signaling or a Physical Downlink Control Channel (PDCCH)/Enhanced Physical Downlink Control Channel (EPDCCH) sent by a network device; and determining a distribution mode according to the value of the configuration information, and determining the uplink subframe occupied by each frequency band in the shared uplink subframe set according to the determined distribution mode.

The high-level signaling or the PDCCH/EPDCCH carries C-bit configuration information, and the value of the configuration information indicates one of D allocation modes of the uplink subframe in the shared uplink subframe set occupied by each frequency band. Wherein, the D distribution modes are pre-configured by the network equipment through high-level signaling or pre-configured with the network equipmentAgreed upon, C = [ log = [ ]₂D]。

Wherein, the high layer signaling or PDCCH/EPDCCH comprises the following situations: higher layer signaling, PDCCH, or EPDCCH; higher layer signaling, or PDCCH; higher layer signaling, or EPDCCH; higher layer signaling, or PDCCH and EPDCCH.

When C =1, the correspondence between the value of the C bit information and the allocation manner is shown in table 2:

TABLE 2

When C =2, the correspondence between the value of the C bit information and the allocation manner is shown in table 3:

TABLE 3

Based on the second mode, when the terminal device aggregates two frequency bands, the allocation mode that each frequency band occupies the uplink subframe in the shared uplink subframe set is as follows:

one frequency band occupies i uplink subframes in the shared uplink subframe set, and the other frequency band occupies N-i uplink subframes in the shared uplink subframe set; wherein, N is the number of uplink sub-frames in the shared uplink sub-frame set, and i is an integer not greater than N/2.

Preferably, the allocation method provided in the embodiment of the present invention is to make the uplink subframes occupied by each frequency band be distributed in one radio frame as uniformly as possible. In the radio frame, subframes are numbered sequentially from 0, and are illustrated in several allocation manners below.

When FDD frame structures are used in both frequency bands, N =10, and the allocation manner of the frequency bands occupying uplink subframes in the shared uplink subframe set includes at least one of the following:

when i =1, one frequency band occupies the uplink subframe with the subframe number of 0 or 5 in the shared uplink subframe set, and the other frequency band occupies the remaining uplink subframes in the shared uplink subframe set (i.e. the uplink subframes except the uplink subframe with the subframe number of 0 in the shared uplink subframe set, or the uplink subframes except the uplink subframe with the subframe number of 5 in the shared uplink subframe set); certainly, an uplink subframe occupied by one frequency band may not be limited to the uplink subframe with the subframe number of 0 or 5, and may also occupy any other uplink subframe in a radio frame, and another frequency band occupies the remaining uplink subframes in the shared uplink subframe set;

when i =2, one frequency band occupies uplink subframes with subframe numbers of 0 and 5, or uplink subframes with subframe numbers of 1 and 6, or uplink subframes with subframe numbers of 2 and 7, or uplink subframes with subframe numbers of 3 and 8, or uplink subframes with subframe numbers of 4 and 9 in a shared uplink subframe set, and the other frequency band occupies the rest uplink subframes in one radio frame; certainly, two uplink subframes occupied by one frequency band may also be two consecutive uplink subframes, for example, uplink subframes with subframe numbers k and k +1, where k = any integer of 0-8, and the other frequency band occupies the remaining uplink subframes in the shared uplink subframe set;

when i =3, one frequency band occupies uplink subframes with subframe numbers of 0, 5 and 9, or uplink subframes with subframe numbers of 1, 5 and 9, or uplink subframes with subframe numbers of 0, 4 and 8, or uplink subframes with subframe numbers of 0, 4 and 9 in the shared uplink subframe set, and the other frequency band occupies the rest uplink subframes in the shared uplink subframe set;

when i =4, one frequency band occupies uplink subframes numbered 0, 3, 6 and 9 in the shared uplink subframe set, and the other frequency band occupies the rest uplink subframes in the shared uplink subframe set;

when i =5, one frequency band occupies the uplink subframe with the even number of the subframe number in the shared uplink subframe set, and the other frequency band occupies the uplink subframe with the odd number of the subframe number in the shared uplink subframe set; or, one frequency band occupies the uplink subframe belonging to the first half frame of a radio frame in the shared uplink subframe set, and the other frequency band occupies the uplink subframe belonging to the second half frame of the radio frame in the shared uplink subframe set.

Wherein, the subframe number is the number in a wireless frame, and starts from 0; for FDD, one wireless frame (wireless frame with an FDD frame structure) comprises 10 uplink subframes, and the subframe number of the uplink subframe in one wireless frame is 0-9; for TDD, the number of the uplink subframe in a radio frame (a radio frame with a TDD frame structure) depends on the used TDD uplink and downlink configuration, for example, when TDD uplink and downlink configuration 0 is used, the number of the uplink subframe in a radio frame is 2, 3, 4, 7, 8, 9, and when TDD uplink and downlink configuration 5 is used, the number of the uplink subframe in a radio frame is 2; the following concept of subframe number is the same here.

When the same uplink/downlink configured TDD frame structure is used in both frequency bands, N is an integer greater than or equal to 2 and less than or equal to 6, and the allocation manner of the uplink subframe in the uplink subframe set shared by each frequency band includes at least one of the following:

and when i =1, one frequency band occupies the uplink subframe with the subframe number of 2 in the shared uplink subframe set, and the other frequency band occupies the rest uplink subframes in the shared uplink subframe set.

And when i =2, one frequency band occupies uplink subframes numbered 2 and 7 in the shared uplink subframe set, and the other frequency band occupies the rest uplink subframes in the shared uplink subframe set.

When i =3, one frequency band occupies uplink subframes with subframe numbers of 2, 4 and 8 in the shared uplink subframe set, or uplink subframes with subframe numbers of 2, 3 and 4, and the other frequency band occupies the rest uplink subframes in the shared uplink subframe set.

Specifically, when the same uplink/downlink configured TDD frame structure is used in both frequency bands, N is an integer greater than or equal to 2 and less than or equal to 6, and the allocation manner in which each frequency band occupies the uplink subframe in the shared uplink subframe set may further include the following manner:

when both frequency bands use the TDD frame structure with uplink/downlink configuration 0, a 1:5 allocation manner may be adopted, for example, one frequency band uses any one uplink subframe (for example, the uplink subframe with subframe number 2, or the uplink subframe with subframe number 3, 4, 5, 8, or 9) in the uplink subframes with subframe numbers 2, 3, 4, 7, 8, or 9, and the other frequency band uses the remaining uplink subframes; a 2:4 allocation mode may also be adopted, for example, one frequency band uses any two uplink subframes (which may be uplink subframes with subframe numbers 2 and 3, or subframe numbers 2 and 4, or subframe numbers 2 and 7, or subframe numbers 2 and 8, or subframe numbers 2 and 9, or subframe numbers 3 and 4, or subframe numbers 3 and 7, or subframe numbers 3 and 8, or subframe numbers 3 and 9, or subframe numbers 4 and 7, or subframe numbers 4 and 8, or subframe numbers 4 and 9, or subframe numbers 7 and 8, or subframe numbers 7 and 9, or subframe numbers 8 and 9) in uplink subframes with subframe numbers 2, 3, 4, 7, 8, or 9), and the other frequency band uses the rest uplink subframes; a 3:3 allocation mode may also be adopted, for example, any three uplink subframes (subframe numbers 2, 3 and 4, subframe numbers 2, 3 and 7, subframe numbers 2, 3 and 8, subframe numbers 2, 3 and 9, subframe numbers 2, 4 and 7, subframe numbers 2, 4 and 8, subframe numbers 2, 4 and 9, subframe numbers 2, 7 and 8, subframe numbers 2, 7 and 9, subframe numbers 3, 4 and 7, subframe numbers 3, 4 and 8, subframe numbers 3, 4 and 9, subframe numbers 3, 7 and 8, subframe numbers 3, 7 and 9, subframe numbers 3, 8 and 9, subframe numbers 4, 9, or subframe numbers 2, 7 and 9 may be used for one frequency band, 7 and 8, or the uplink subframes with subframe numbers of 4, 7 and 9, or the uplink subframes with subframe numbers of 4, 8 and 9, or the uplink subframes with subframe numbers of 7, 8 and 9), and the other frequency band uses the rest uplink subframes;

when both frequency bands use the TDD frame structure of uplink/downlink configuration 1, a 1:3 allocation manner may be adopted, for example, one frequency band uses any one uplink subframe (for example, the uplink subframe with subframe number 2, or the uplink subframe with subframe number 3, 7, or 8) in uplink subframes with subframe numbers 2, 3, 7, or 8, and the other frequency band uses the remaining uplink subframes; a 2:2 allocation manner may also be adopted, for example, one frequency band uses any two uplink subframes in uplink subframes with subframe numbers 2, 3, 7, or 8 (for example, uplink subframes with subframe numbers 2 and 3, or subframe numbers 2 and 7, or subframe numbers 2 and 8, or subframe numbers 3 and 7, or subframe numbers 3 and 8, or subframe numbers 7 and 8), and the other frequency band uses the remaining uplink subframes;

when the two frequency bands both use the TDD frame structure with the uplink/downlink configuration 2 or 4, a 1:1 allocation mode can be adopted, wherein one frequency band uses the uplink subframe with the subframe number of 2, and the other frequency band uses the uplink subframe with the subframe number of 7;

when both frequency bands use the TDD frame structure of uplink/downlink configuration 3, a 1:2 allocation manner may be adopted, for example, one frequency band uses any one uplink subframe (for example, an uplink subframe with a subframe number of 2, an uplink subframe with a subframe number of 3, or an uplink subframe with a subframe number of 3 or 4) in uplink subframes with a subframe number of 2, 3, or 4, and the other frequency band uses the remaining uplink subframes;

when both frequency bands use the TDD frame structure of uplink/downlink configuration 6, a 1:4 allocation manner may be adopted, for example, one frequency band uses any one uplink subframe (for example, the uplink subframe may be numbered 2, or the uplink subframe may be numbered 3, or 4, or 7, or 8) in the uplink subframes with the subframe numbers 2, 3, 4, 7, or 8, and the other frequency band uses the remaining uplink subframes; a 2:3 allocation manner may also be adopted, for example, one frequency band uses any two uplink subframes in uplink subframes with subframe numbers 2, 3, 4, 7 or 8 (for example, uplink subframes with subframe numbers 2 and 3, or subframe numbers 2 and 4, or subframe numbers 2 and 7, or subframe numbers 2 and 8, or subframe numbers 3 and 4, or subframe numbers 3 and 7, or subframe numbers 3 and 8, or subframe numbers 4 and 7, or subframe numbers 4 and 8, or subframe numbers 7 and 7), and the other frequency band uses the rest uplink subframes.

When two frequency bands respectively use different uplink/downlink configured TDD frame structures, or when one frequency band uses a TDD frame structure and the other frequency band uses an FDD frame structure, N is an integer greater than or equal to 1 and less than or equal to 6, and the allocation mode of each frequency band for occupying uplink subframes in the shared uplink subframe set includes at least one of the following:

and when i =0, one frequency band does not occupy the uplink subframe in the shared uplink subframe set, and the other frequency band occupies all the uplink subframes in the shared uplink subframe set. For example, when the number of uplink subframes in the frequency band 1 is greater than that in the frequency band 2, the allocation may be according to 0: N, assuming that aggregation conditions of different TDD uplink and downlink configurations of a 5ms uplink and downlink switching point period are: the frequency band 1 uses TDD uplink/downlink configuration 1, and when the frequency band 2 uses TDD uplink/downlink configuration 2, the allocation may be according to 0:2, that is, the frequency band 1 does not use any subframe in the shared uplink subframe, uplink subframes with subframe numbers 2 and 7 are used for the frequency band 2, and the frequency band 1 performs uplink transmission in the corresponding uplink subframes with subframe numbers 3 and 8 that do not belong to the shared set. And assuming the aggregation condition of the TDD uplink and downlink configuration with the 5ms uplink and downlink switching point period and the TDD uplink and downlink configuration with the 10ms uplink and downlink switching point period: the frequency band 1 uses TDD uplink/downlink configuration 2, and when the frequency band 2 uses TDD uplink/downlink configuration 5, the allocation may be according to 0:1, that is, the frequency band 1 does not use any subframe in the shared uplink subframe, the uplink subframe numbered 2 is used for the frequency band 2, and the frequency band 1 performs uplink transmission in the corresponding subframe 7 not belonging to the shared set. Further, assuming that the frequency band 1 uses an FDD frame structure, when the frequency band 2 uses TDD uplink/downlink configuration 1, the allocation may be according to 0:4, that is, the frequency band 1 does not use any subframe in the shared uplink subframe, uplink subframes with subframe numbers of 2, 3, 7, and 8 are used for the frequency band 2, and the frequency band 1 performs uplink transmission in the corresponding uplink subframes with subframe numbers of 0, 1, 4, 5, 6, and 9, which do not belong to the shared set.

And when i =1, one frequency band occupies the uplink subframe with the subframe number of 2 in the shared uplink subframe set, and the other frequency band occupies the rest uplink subframes in the shared uplink subframe set. For example, the aggregation situation of different TDD uplink and downlink configurations of the 5ms uplink and downlink switching point period is as follows: assuming that the frequency band 1 uses TDD uplink and downlink configuration 2, the frequency band 2 uses TDD uplink and downlink configuration 1, the shared uplink subframe set includes uplink subframes numbered 2 and 7 in a radio frame, the frequency band 1 can occupy the uplink subframe numbered 2 in the shared uplink subframe set, the frequency band 2 can occupy the uplink subframe numbered 7 in the shared uplink subframe set, and in addition, the frequency band 2 can also use uplink subframes not belonging to the uplink subframe shared by multiple frequency bands in its own TDD uplink and downlink configuration (configuration 1), that is, uplink subframes numbered 3 and 8; for another example, the aggregation situation of different TDD uplink and downlink configurations of the 10ms uplink and downlink switching point period is as follows: assuming that the frequency band 1 uses TDD uplink and downlink configuration 3, the frequency band 2 uses TDD uplink and downlink configuration 4, the shared uplink subframe set includes uplink subframes numbered 2 and 3 in a radio frame, the frequency band 1 can occupy uplink subframes numbered 2 in the shared uplink subframe set, the frequency band 2 can occupy uplink subframes numbered 3 in the shared uplink subframe set, and in addition, the frequency band 1 can also use uplink subframes not belonging to the uplink subframes shared by multiple frequency bands in its own TDD uplink and downlink configuration (configuration 3), that is, uplink subframes numbered 4; for another example, the aggregation between the TDD uplink/downlink configuration with the 5ms uplink/downlink switching point period and the TDD uplink/downlink configuration with the 10ms uplink/downlink switching point period is as follows: suppose that the frequency band 1 uses TDD uplink and downlink configuration 1, the frequency band 2 uses TDD uplink and downlink configuration 3, the shared uplink subframe set includes uplink subframes with subframe numbers 2 and 3 in a radio frame, the frequency band 1 can occupy uplink subframes with subframe number 2 in the shared uplink subframe set, the frequency band 2 can occupy uplink subframes with subframe number 3 in the shared uplink subframe set, in addition, the frequency band 1 can also use uplink subframes which do not belong to multiband shared uplink subframes in its own TDD uplink and downlink configuration (configuration 1), i.e. uplink subframes with subframe numbers 7 and 8, and the frequency band 2 can also use uplink subframes which do not belong to multiband shared uplink subframes in its own TDD uplink and downlink configuration (configuration 3), i.e. uplink subframes with subframe number 4.

And when i =2, one frequency band occupies uplink subframes numbered 2 and 7 in the shared uplink subframe set, and the other frequency band occupies the rest uplink subframes in the shared uplink subframe set. The method is more suitable for the situation of different TDD uplink and downlink configuration aggregation and FDD and TDD aggregation situations of a 5ms uplink and downlink switching point period, for example, suppose that a frequency band 1 uses TDD uplink and downlink configuration 1, a frequency band 2 uses TDD uplink and downlink configuration 0, a shared uplink subframe set comprises uplink subframes with the subframe numbers of 2, 3, 7 and 8 in a wireless frame, the frequency band 1 can occupy uplink subframes with the subframe numbers of 2 and 7 in the shared uplink subframe set, the frequency band 1 can occupy uplink subframes with the subframe numbers of 3 and 8 in the shared uplink subframe set, and in addition, the frequency band 2 can also use uplink subframes which do not belong to the uplink subframes shared by multiple frequency bands in the own TDD uplink and downlink configuration (configuration 0), namely, the uplink subframes with the subframe numbers of 4 and 9.

For example, if one frequency band uses a TDD frame structure with uplink/downlink configuration of 1, and the other frequency band uses an FDD frame structure, the method includes 3 allocation manners of i =0, i =1, and i = 2. For another example, if one frequency band uses a TDD frame structure with uplink and downlink configuration 1, and the other frequency band uses a TDD frame structure with uplink/downlink configuration 5, the allocation method with i =0 is included.

Preferably, for the first implementation manner, the configuration information may also perform an uplink subframe allocation indication on the shared uplink subframe according to the uplink subframe allocation manner in the second implementation manner, that is, preferably, the configuration information in the first implementation manner indicates that the uplink subframe occupied by each frequency band satisfies the uplink subframe allocation manner in the second implementation manner.

In the embodiment of the invention, PDCCH/EPDCCH represents that: including one of PDCCH, EPDCCH, or including both PDCCH and EPDCCH.

Specifically, the uplink subframe in the shared uplink subframe set indicated in the configuration information is determined as the uplink subframe occupied by the frequency band receiving the PDCCH/EPDCCH in the shared uplink subframe set.

When the PDCCH/EPDCCH carries an uplink scheduling grant (UL grant), the configuration information indicates an uplink subframe used for transmitting the PUSCH scheduled by the UL grant on the frequency band where the PDCCH/EPDCCH is received; when the PDCCH/EPDCCH carries a downlink scheduling grant (DL grant) or the PDCCH/EPDCCH is a PDCCH/EPDCCH indicating release of downlink semi-persistent scheduling (SPS) resources, the configuration information indicates an uplink subframe for transmitting acknowledgement/negative acknowledgement (ACK/NACK) information of a downlink subframe where the PDCCH/EPDCCH is located on a frequency band where the PDCCH/EPDCCH is received.

It is preferable thatIn the third embodiment, the bit field occupied by the configuration information may further include G bits, G = [ log = [ log ]₂H]And H is the number of uplink subframes in the shared uplink subframe set, and the value of the bit field occupied by the configuration information indicates the number of the uplink subframe in the shared uplink subframe set. For example, the shared uplink subframe set includes uplink subframes with subframe numbers 2, 3, 4, 7, 8, and 9. The uplink subframe with the subframe number of 2 is numbered 1 in the set, the uplink subframe with the subframe number of 3 is numbered 2 in the set, the uplink subframe with the subframe number of 4 is numbered 3 in the set, the uplink subframe with the subframe number of 7 is numbered 4 in the set, the uplink subframe with the subframe number of 8 is numbered 5 in the set, and the uplink subframe with the subframe number of 9 is numbered 6 in the set.

If the uplink subframe is sent by multiple network devices, the terminal may, but is not limited to, determine the uplink subframe occupied by each frequency band by using the configuration information carried in the first received higher layer signaling.

In the embodiment of the network device side method of the present invention, technical features the same as or similar to those of the embodiment of the terminal device side exist, and the description may refer to the implementation manner of the terminal device side, and are not repeated here.

Preferably, in the present invention, the serving base stations of the terminal device operating in different frequency bands are different. For example, a frequency band 1 and a frequency band 2 are aggregated by a carrier of a terminal device, the frequency band 1 is served by a base station a, the frequency band 2 is served by a base station B, in a downlink subframe, the terminal device may receive downlink data on downlink carriers in the frequency bands 1 and 2 at the same time, the downlink data in the frequency band 1 (including but not limited to downlink channel transmission such as PDCCH, EPDCCH, PDSCH, PBCH, PHICH, PCFICH, PMCH, and the like, the same applies hereinafter) is scheduled and transmitted by the base station a, and the downlink data in the frequency band 2 is scheduled and transmitted by the base station B; the base station A and the base station B schedule the terminal equipment independently; specifically, for the bearer split scenario, one base station (e.g., base station a) is responsible for sending configuration information related to higher layer signaling, i.e., maintaining the connection between the terminal device and the user plane on the network side, and the other base station (e.g., base station B) is responsible for sending downlink service information (i.e., the above-mentioned downlink data), i.e., maintaining the connection between the terminal device and the data plane on the network side; in an uplink subframe, a terminal device transmits uplink data on a frequency band, the uplink data being received by a base station serving the frequency band; that is, in the uplink subframe corresponding to the frequency band 1, the base station a receives the uplink data transmitted by the terminal device on the frequency band 1, and in the uplink subframe corresponding to the frequency band 2, the base station B receives the uplink data transmitted by the terminal device on the frequency band 2.

When the network device sends the configuration information to the terminal device, the network device serving one frequency band (the main network device) can determine the uplink subframes occupied by each frequency band of the terminal device carrier aggregation in the shared uplink subframe set, and notifying the uplink subframe occupied by each frequency band of the carrier aggregated by the terminal device in the shared uplink subframe set to other network devices serving each frequency band, wherein the configuration information indicating the uplink subframe occupied by each frequency band of the carrier aggregated by the terminal device in the shared uplink subframe set can be sent to the terminal device only by the main network device, or can be sent to the terminal device by a plurality of network devices serving different frequency bands (at this time, the configuration information sent to the terminal device by each network device should consistently indicate the same uplink subframe allocation condition, or the configuration information sent to the terminal device by each network device indicates the uplink subframe occupied by the frequency band served by the network device respectively). Or negotiating among other network devices serving frequency bands in advance to determine the uplink subframe occupied by each frequency band in the carrier aggregation in the shared uplink subframe set.

When a mode of sending configuration information by a base station is adopted to inform an uplink subframe occupied by each frequency band of terminal equipment in a shared uplink subframe set, the configuration information can be sent to the terminal equipment by only one service base station, for a scene that one frequency band is deployed into a Macro cell and the other frequency band is deployed into a small cell, the configuration information is usually sent to the terminal by the base station of the Macro cell, and the configuration condition of the uplink subframe occupied by the frequency band of the small cell can be obtained by the base station of the small cell through information interaction with the base station of the Macro cell in advance; or the multiple serving base stations may send the configuration information to the terminal device simultaneously or respectively, for example, the base stations of the Macro cell and the small cell both send the configuration information to the terminal device, the base stations of the Macro cell and the small cell send the same configuration information to the terminal device, and both indicate specific allocation of the shared uplink subframe between the Macro cell and the small cell, or the base stations of the Macro cell and the small cell send different configuration information to the terminal device, the configuration information sent by the base station of the Macro cell to the terminal device indicates an uplink subframe situation occupied by the Macro cell in the shared uplink subframe, and the configuration information sent by the base station of the Mmall cell to the terminal device indicates an uplink subframe situation occupied by the small cell in the shared uplink subframe.

There are various implementation manners in which the network device determines the uplink subframe occupied by each frequency band of carrier aggregation in the shared uplink subframe set, and sends configuration information to the terminal device, and the following examples illustrate several implementation manners in which uplink subframes are allocated to each frequency band and configuration information is sent to the terminal device.

The first implementation manner of allocating uplink subframes for each frequency band and sending configuration information to the terminal device is as follows:

Preferably, the allocation is performed according to the traffic sizes (which may include uplink traffic and downlink traffic) of different frequency bands, more uplink subframes are allocated to the frequency band with larger traffic (such as the frequency band of small cell service), and less uplink subframes are allocated to the frequency band with less traffic (such as the frequency band of Marco cell service).

Specifically, if the predetermined rule is predetermined with the terminal device, the predetermined rule may be jointly determined with the terminal by using the network device of each frequency band.

Preferably, when the network device sends the PDCCH/EPDCCH to the terminal device, the network device serving the frequency band sends the PDCCH/EPDCCH to the terminal device on the frequency band; for example, for a scenario in which one frequency band 1 is deployed as a Macro cell and another frequency band 2 is deployed as a small cell, on the frequency band 1, the Macro cell base station transmits a PDCCH/EPDCCH (and a PDSCH scheduled by the PDCCH/EPDCCH) to the terminal device, and on the frequency band 2, the small cell base station transmits the PDCCH/EPDCCH (and a PDSCH scheduled by the PDCCH/EPDCCH) to the terminal device. The following situation that the network device sends PDCCH/EPDCCH to the terminal device is the same as here, and is not described again.

Based on the second implementation manner, when the terminal device aggregates two frequency bands, the allocation manner of each frequency band occupying the uplink subframe in the shared uplink subframe set is as follows: one frequency band occupies i uplink subframes in the shared uplink subframe set, and the other frequency band occupies N-i uplink subframes in the shared uplink subframe set; wherein, N is the number of uplink sub-frames in the shared uplink sub-frame set, and i is an integer not greater than N/2.

Specifically, when the FDD frame structures are used in both frequency bands, N =10, the allocation manner in which each frequency band of the terminal device occupies the uplink subframe in the shared uplink subframe set may include at least one of the following:

when i =4, one frequency band occupies uplink subframes with subframe numbers of 0, 3, 6 and 9 in the shared uplink subframe set, and the other frequency band occupies the rest uplink subframes in the shared uplink subframe set;

when i =5, one frequency band occupies the uplink subframe with even number of the subframe number in the shared uplink subframe set, and the other frequency band occupies the uplink subframe with odd number of the subframe number in the shared uplink subframe set; or, one frequency band occupies the uplink subframe belonging to the first half frame of a radio frame in the shared uplink subframe set, and the other frequency band occupies the uplink subframe belonging to the second half frame of the radio frame in the shared uplink subframe set.

When the same uplink/downlink configured TDD frame structure is used in both frequency bands, where N is an integer greater than or equal to 2 and less than or equal to 6, and a distribution manner in which each frequency band of the terminal device occupies an uplink subframe in the shared uplink subframe set includes at least one of the following:

and when i =3, one frequency band occupies uplink subframes with the subframe numbers of 2, 4 and 8 in the shared uplink subframe set, or the uplink subframes with the subframe numbers of 2, 3 and 4, and the other frequency band occupies the rest uplink subframes in the shared uplink subframe set.

When two frequency bands respectively use different uplink/downlink configured TDD frame structures, or when one frequency band uses a TDD frame structure and the other frequency band uses an FDD frame structure, N is an integer greater than or equal to 1 and less than or equal to 6, and the allocation manner in which each frequency band of the terminal device occupies the uplink subframe in the shared uplink subframe set includes at least one of:

when i =0, one frequency band does not occupy the uplink subframe in the shared uplink subframe set, and the other frequency band occupies all the uplink subframes in the shared uplink subframe set;
