Description

Method, device and system for transmitting uplink service data

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a method, an apparatus, and a system for transmitting uplink service data.

Background

In an LTE (Long Term Evolution ) network, when a UE (User Equipment) has uplink service data and uplink control information to transmit to a base station, if the transmission of the uplink service data and the uplink control information overlap in a time domain, the UE may transmit the uplink control information together as a part of the uplink service data, that is, in an UCI piggyback mode in the LTE. Compared with the independent transmission of the uplink control information and the uplink service data, the uplink service data and the uplink control information are simultaneously transmitted by using the UCI piggyback mode, so that the peak-to-average ratio of uplink transmission can be reduced, and the complicated uplink power control and the like are avoided.

In 5G (fifth generation communication and mobile technology), in order to better support the use of multi-beam large-scale antennas, some uplink control information, such as CSI (channel state information), is divided into two parts, i.e., a first part of uplink control information and a second part of uplink control information in 5G. The data volume of the first part of uplink control information and the number of occupied time-frequency resource blocks can be determined by the base station according to the system configuration, while the data volume of the second part of uplink control information and the number of occupied time-frequency resource blocks can not be determined by the base station in advance and can only be known after the first part of uplink control information is recovered correctly.

If there is uplink service data and uplink control information to be transmitted to the base station at the same time in the 5G, the UE may also transmit the uplink service data and the uplink control information at the same time by using the UCI piggyback mode in LTE. After receiving the uplink service data, the first part and the second part of the uplink control information, the base station should first determine the position of the time-frequency resource occupied by the first part of the uplink control information according to the system configuration and the preset mapping rule of the time-frequency resource, then recover the first part of the uplink control information from the time-frequency resource according to the position, determine the position of the time-frequency resource occupied by the second part of the uplink control information according to the first part of the uplink control information, then determine the position of the time-frequency resource block occupied by the uplink service data according to the positions of the time-frequency resource block occupied by the first part of the uplink control information and the second part of the uplink control information, and recover the uplink service data.

In the course of implementing the present disclosure, the inventors found that the prior art has at least the following problems:

in 5G, if the uplink service data is to be recovered, the content of the first part of the uplink control information needs to be recovered first, the position of the time-frequency resource occupied by the second part of the uplink control information is determined according to the first part of the uplink control information, and the uplink service data can be recovered according to the positions of the time-frequency resource occupied by the first part of the uplink control information and the second part of the uplink control information. In addition, the process of recovering the first part of uplink control information by the base station can increase the delay of uplink data reception.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

An exemplary embodiment of the present disclosure provides a method for transmitting uplink service data, and an execution subject of the method for transmitting uplink service data may be a base station and a UE.

The base station may be provided with a processor, a transceiver, a memory, and the like, where the processor may be used for related processing of transmitting uplink service data, the transceiver may be used for receiving and transmitting data, and the memory may be used for transmitting data required and generated in the uplink service data process.

The UE may be a mobile phone or the like, and the UE may be provided with a processor, a transceiver, a memory, and the like, where the processor may be used for related processing of transmitting uplink service data, the transceiver may be used for receiving and sending data, and the memory may be used for transmitting data required and generated in the uplink service data process. The UE may further be provided with an input/output device such as a screen for displaying service data and the like.

Before implementation, as shown in fig. 1, an application scenario of the embodiment of the present disclosure is first introduced, where devices involved in the application scenario include a base station and a UE, the UE may be a mobile phone, and the UE may send uplink control information and uplink service data together through time-frequency resources, and the base station may recover the uplink service data and the uplink control information sent by the UE from the time-frequency resources.

As shown in fig. 2, the processing flow of the method may include the following steps:

in step 201, the UE determines the time-frequency resource allocated to the UE, and the uplink service data and uplink control information to be transmitted.

The uplink control information at least includes a first Part of uplink control information and a second Part of uplink control information, where the first Part of uplink control information may be Part1 (a first Part) in CSI, and the second Part of uplink control information may be Part2 (a second Part) in CSI.

In implementation, when the UE has uplink service data and uplink control information to send to the base station, an SR (Scheduling Request) may be sent to the base station, and after receiving the uplink Scheduling Request sent by the UE, the base station may allocate a small portion of time-frequency resources for the UE to upload a BSR (buffer state report) for the UE, and the UE may notify the base station through the BSR of the data amount of the uplink service data and the uplink control information to be uploaded, and after receiving the BSR, the base station allocates corresponding uplink time-frequency resources for the UE to transmit the uplink service data and the uplink control information. After the base station determines the time-frequency resources allocated to the UE, the base station may notify the UE of the allocation result, so that the UE may determine the time-frequency resources allocated to itself.

In step 202, the UE determines, according to a preset first system configuration and a preset first time-frequency resource mapping rule, a first position of a time-frequency resource occupied by the first part of uplink control information in the time-frequency resources allocated to the UE.

For example, the preset first system configuration specifies a method for calculating the number of resource units of the time-frequency resource occupied by the first part of uplink control information, and the like, and the preset first time-frequency resource mapping rule generally includes a time-domain priority mapping rule, a frequency-domain priority mapping rule, and the like.

In implementation, after determining the time-frequency resource allocated to the UE, the UE determines the content and data amount of the first part of uplink control information, may then obtain the stored preset first system configuration, and calculate the number of resource units of the time-frequency resource occupied by the first part of uplink control information by using the preset first system configuration, the data amount of the first part of uplink control information, the channel measurement result, and the like. And then, determining a first position of a time-frequency resource occupied by the first part of uplink control information by using a preset first time-frequency resource mapping rule. For example, as shown in fig. 3, the preset first time-frequency resource mapping rule is a frequency domain first rule, the number of resource units of the time-frequency resource occupied by the first part of uplink control information is 5, and the first position is 5 resource units on a frequency domain adjacent to a DMRS (Demodulation Reference Signal).

Optionally, the preset first time-frequency resource mapping rule is a time-domain first mapping rule or a frequency-domain first mapping rule.

In implementation, the base station and the UE use the same first time-frequency resource mapping rule, which may be that the base station and the UE negotiate in advance, the preset first time-frequency resource mapping rule may be a time domain first mapping rule or a frequency domain first mapping rule, the time domain first mapping rule refers to mapping data to a time domain first and then considering the frequency domain, and the frequency domain first mapping rule refers to mapping data to the frequency domain first and then considering the time domain.

In step 203, the UE determines the starting position of the resource unit of the time-frequency resource occupied by each CB of the uplink service data according to the preset second time-frequency resource mapping rule and the time-frequency resource allocated to the device except the time-frequency resource occupied by the first part of the uplink control information.

The preset second time-frequency resource mapping rule may be preset by a technician and stored in the UE and the base station, and the second time-frequency resource mapping rule may be the same as or different from the first time-frequency resource mapping rule, for example, the first time-frequency resource mapping rule and the second time-frequency resource mapping rule are both frequency domain priority mapping rules, or the first time-frequency resource mapping rule is a time domain priority mapping rule, and the second time-frequency resource mapping rule is a frequency domain priority mapping rule, or the first time-frequency resource mapping rule is a frequency domain priority mapping rule, and the second time-frequency resource mapping rule is a time domain priority mapping rule.

In implementation, the uplink service data is generally a bit stream, and the UE divides the bit stream into a plurality of bit stream segments according to a certain principle, and then encodes the plurality of bit stream segments according to a preset encoding method to obtain a plurality of CBs (Code blocks). It should be noted here that the manner of dividing the bit stream into the multiple bit stream segments is well agreed by the base station and the UE, and the bit number of each CB may be the same or different, for example, in LTE, the bit number of each CB before encoding does not exceed 6144 bits, and when the bit number of the data to be transmitted exceeds 6144 bits, the data to be transmitted is divided into multiple CBs as uniformly as possible.

After determining the first position of the time-frequency resource occupied by the first part of the uplink control information, the UE may use the first position to remove the time-frequency resource occupied by the first part of the uplink control information from the time-frequency resource allocated to the UE, but not remove the time-frequency resource occupied by the second part of the uplink control information, so as to obtain the first time-frequency resource. If the time frequency resources required by the data volume of the plurality of CBs of the uplink service data are larger than the first time frequency resources, the processing of deleting the bit position can be respectively carried out on each CB, so that the plurality of CBs of the uplink service data can be matched with the first time frequency resources, and if the time frequency resources required by the data volume of the plurality of CBs of the uplink service data are smaller than the first time frequency resources, the processing of sending the redundant bit position can be respectively carried out on each CB, so that the plurality of CBs of the uplink service data can be matched with the first time frequency resources. And then calculating the initial position of the resource unit of the time-frequency resource occupied by each CB by using the data volume of the data mapped by each resource unit, the channel measurement result and the like. For example, as shown in fig. 4, there are 4 CBs for the uplink service data, which are CB1, CB2, CB3 and CB4, where the time-frequency resource occupied by CB1 is the time-frequency resource between the first thick horizontal line and the second thick horizontal line counted from the left, the time-frequency resource occupied by CB2 is the time-frequency resource between the second thick horizontal line and the third thick horizontal line counted from the left, the time-frequency resource occupied by CB3 is the time-frequency resource between the third thick horizontal line and the fourth thick horizontal line counted from the left, the time-frequency resource occupied by CB4 is the time-frequency resource between the fourth thick horizontal line and the last thick horizontal line counted from the left, and the starting positions of CB1, CB2, CB3 and CB4 are the first thick black line, the second thick black line, the third thick black line and the fourth thick black line.

Similarly, after the start position of the time-frequency resource occupied by each CB is determined, the end position of the time-frequency resource occupied by each CB can be actually determined.

Optionally, the UE may determine the starting position of the resource unit of the time-frequency resource occupied by each CB by using the number of the resource units of the time-frequency resource occupied by each CB, and the corresponding processing may be as follows:

and determining the third number of resource units of the time-frequency resources occupied by each CB according to the time-frequency resources distributed to the equipment except the time-frequency resources occupied by the first part of the uplink control information, and determining the initial positions of the resource units of the time-frequency resources occupied by each CB according to the preset second time-frequency resource mapping rule and the third number of the resource units of the time-frequency resources occupied by each CB.

In implementation, the UE may determine, by using the first location, the time-frequency resource allocated to the UE, without the time-frequency resource occupied by the first part of the uplink control information, and then perform rate matching (the rate matching method is the same as that described above), and determine, by using the data amount of each CB and the data amount of the data mapped by each resource unit, the third number of resource units of the time-frequency resource occupied by each CB.

For the first CB, in the time-frequency resources allocated to the first CB except the time-frequency resources occupied by the first part of the uplink control information, according to a preset second time-frequency resource mapping rule, the starting position of the time-frequency resources is the starting position of the first CB, for the second CB, a third number of resource units corresponding to the first CB are counted backwards from the starting position, the starting position of the second CB is the starting position of the first CB, and so on, the starting position of the time-frequency resources occupied by each CB can be determined.

In step 204, the UE determines, according to a preset second system configuration and the second part of uplink control information, a first number of resource units of the time-frequency resource occupied by the second part of uplink control information.

Wherein the second system configuration may be preset by a technician and stored to the UE and the base station. A method for calculating the number of resource units of the time-frequency resource occupied by the second part of uplink control information is specified in the preset second system configuration.

In implementation, after performing first rate matching on each CB of the uplink service data, the UE may determine a second portion of uplink control information to be sent, and further determine content and data volume of the second portion of uplink control information, and then calculate, by using a preset second system configuration, a first number of resource units of time-frequency resources occupied by the second portion of uplink control information based on the data volume of the second portion of uplink control information.

In step 205, the UE determines a second number of resource units of the time-frequency resource respectively occupied by each CB according to the time-frequency resource allocated to the UE excluding the time-frequency resources occupied by the first part of the uplink control information and the second part of the uplink control information.

In implementation, after the UE determines the second number of time-frequency resources occupied by the second portion of uplink control information, the UE may use the first position to obtain the number of resource units of the time-frequency resources occupied by the first portion of uplink control information, then use the first number and the number to remove the time-frequency resources occupied by the first portion of uplink control information and the second portion of uplink control information from the time-frequency resources allocated to the UE to obtain the second time-frequency resources, and then use the second time-frequency resources to perform rate matching processing on each CB (the same as the rate matching processing in step 203, which is not described here again), so as to obtain the second number of resource units of the time-frequency resources respectively occupied by each CB. For example, as shown in fig. 5, the first number of resource units of the time-frequency resource occupied by the second part of the uplink control information is 9, the uplink service data has 4 CBs, which are CB1, CB2, CB3 and CB4, after performing rate matching, the time-frequency resource occupied by CB1 is the time-frequency resource between the first thick horizontal line and the second thick horizontal line counted from the left, the time-frequency resource occupied by CB2 is the time-frequency resource between the third thick horizontal line and the fourth thick horizontal line counted from the left, the time-frequency resource occupied by CB3 is the time-frequency resource between the fifth thick horizontal line and the sixth thick horizontal line counted from the left, the time-frequency resource occupied by CB4 is the time-frequency resource between the seventh thick horizontal line and the eighth thick horizontal line counted from the left, and the second numbers of resource units occupied by CB1, CB2, CB3 and CB4 are 31, 37, respectively.

It should be noted that, for any CB, when rate matching is performed twice, since the used time-frequency resources are different (the time-frequency resources after only the time-frequency resources occupied by the first part of uplink control information are removed are used for the first time, and the time-frequency resources after the time-frequency resources occupied by the first part of uplink control information and the second part of uplink control information are removed are used for the second time), the number of resource units of the occupied time-frequency resources is determined to be different. For any CB, the number of resource units occupied by the CB after the first rate matching is greater than the first number of resource units occupied by the CB after the second rate matching, which is because the time-frequency resources occupied by the uplink service data are reduced after the second rate matching, and the reduced time-frequency resources are used for transmitting the second part of uplink control information.

In step 206, the second position of the time-frequency resource occupied by each CB is determined according to the starting position of the resource unit of the time-frequency resource occupied by each CB, the second number of the resource units of the time-frequency resource occupied by each CB, and the preset second time-frequency resource mapping rule.

In implementation, after performing the second rate matching process on each CB, the UE obtains the determined start position of the CB and the second number of occupied resource units for any CB, and may use the second time-frequency resource mapping rule to count the second number of resource units from the start position of the CB, so as to determine the second position of the time-frequency resource occupied by the CB. The second position of the time frequency resource occupied by each CB can be determined by using the same method.

In step 207, the UE maps the first part of the uplink control information, the second part of the uplink control information, and each CB to the time-frequency resource allocated to the UE for transmission according to the first location and the second location.

In implementation, after determining the second location of the time-frequency resource occupied by each CB, the UE may map a first portion of the uplink control information to the first location, map each CB to the corresponding second location, determine the time-frequency resource allocated to the UE excluding the time-frequency resource occupied by the first portion of the uplink control information and the uplink service data, and map the second portion of the uplink control information to the determined time-frequency resource for transmission.

Optionally, a third position of the time-frequency resource occupied by the second part of the uplink control information may be determined first, and then mapping is performed, and the corresponding processing in step 207 may be as follows:

and determining a third position of the time-frequency resource occupied by the second part of uplink control information in the time-frequency resource which is distributed to the equipment and is removed from the time-frequency resource occupied by the first part of uplink control information and the uplink service data, and mapping the first part of uplink control information, the second part of uplink control information and each CB to the first position, the third position and the second position respectively for transmission.

In implementation, after determining the second position of the time-frequency resource occupied by each CB, the UE may determine, by using the first position, the time-frequency resource occupied by the first portion of the uplink control information in the time-frequency resource allocated to the UE, and determine, by using the second position corresponding to each CB, the time-frequency resource occupied by each CB in the time-frequency resource allocated to the UE. And then, in the time frequency resources distributed to the user, removing the time frequency resources occupied by the first part of the uplink control information and each CB to obtain the remaining time frequency resources, wherein the remaining time frequency resources are the time frequency resources occupied by the second part of the uplink control information, and thus, the positions of the remaining time frequency resources are the third positions.

After the UE determines the first location, the second location, and the third location, the UE may map the first portion of uplink control information to the first location, map the second portion of uplink control information to the third location, and map each CB to its corresponding second location for transmission.

As shown in fig. 5, the uplink service data has 4 CBs, which are CB1, CB2, CB3 and CB4, the time frequency resource occupied by CB1 is the time frequency resource between the first thick horizontal line and the second thick horizontal line counted from the left, the time frequency resource occupied by CB2 is the time frequency resource between the third thick horizontal line and the fourth thick horizontal line counted from the left, the time frequency resource occupied by CB3 is the time frequency resource between the fifth thick horizontal line and the sixth thick horizontal line counted from the left, the time frequency resource occupied by CB4 is the time frequency resource between the seventh thick horizontal line and the eighth thick horizontal line counted from the left, the time frequency resource occupied by the second portion of uplink control information is the time frequency resource between the second thick horizontal line and the third thick horizontal line counted from the left, the time frequency resource between the fourth thick horizontal line and the fifth thick horizontal line counted from the left, and the time frequency resource between the sixth thick horizontal line and the seventh horizontal line counted from the left, Counting the time frequency resources between the eighth thick horizontal line and the ninth thick horizontal line from the left.

In step 208, the base station receives uplink control information and uplink service data transmitted by the UE through the time-frequency resource allocated to the UE.

In implementation, the base station may receive uplink traffic data and uplink control information transmitted by the UE on the time-frequency resource allocated to the UE.

In step 209, the base station determines a first position of the time-frequency resource occupied by the first part of the uplink control information according to a preset first system configuration, a preset first time-frequency resource mapping rule, and the time-frequency resource allocated to the UE.

Here, the first system configuration is the same as the first system configuration in step 202.

In implementation, after the base station determines the time-frequency resource allocated to the UE, the base station may determine the data amount of the first part of uplink control information based on a convention with the UE in advance, then may obtain a stored preset first system configuration, and calculate the number of resource units of the time-frequency resource occupied by the first part of uplink control information by using the preset first system configuration and the data amount of the first part of uplink control information. And then, determining a first position of the time frequency resource occupied by the first part of the uplink control information by using a preset time frequency resource mapping rule.

The base station and the UE agree on the data amount of the first part of uplink control information, and therefore, the data amount of the first part of uplink control information can be obtained without knowing the content of the first part of uplink control information.

In step 210, the base station determines the starting position of the resource unit of the time-frequency resource occupied by each CB of the uplink service data according to the preset second time-frequency resource mapping rule and the time-frequency resource allocated to the UE except the time-frequency resource occupied by the first part of the uplink control information.

In the implementation, the base station may use the first position of the resource unit of the time-frequency resource occupied by the first part of the uplink control information, only the time-frequency resources occupied by the first part of uplink control information are removed from the time-frequency resources allocated to the UE, but does not remove the time frequency resource occupied by the second part of the uplink control information to obtain a third time frequency resource, wherein the third time frequency resource is the same as the previous first time frequency resource, then, the uplink scheduling request may be sent according to the data amount of the uplink service data, determining the number of CBs included in the uplink service data and the data volume of each CB according to a preset bit stream division rule, then in a third time-frequency resource, rate matching is carried out on each CB of the uplink service data, so that the uplink service data can be just mapped to a third time frequency resource, thus, the starting position of the resource unit of the time-frequency resource occupied by each CB is obtained.

Optionally, the base station may determine the starting position of the resource unit of the time-frequency resource occupied by each CB by using the number of the resource units occupied by each CB, and the corresponding processing in step 210 may be as follows: determining a first number of resource units of time-frequency resources occupied by each CB of uplink service data respectively according to a preset second system configuration, a first position and the time-frequency resources distributed to the UE, wherein the time-frequency resources are only the time-frequency resources occupied by the first part of uplink control information; and determining the initial position of the resource unit of the time-frequency resource occupied by each CB according to the first number of the resource units of the time-frequency resource occupied by each CB and a preset second time-frequency resource mapping rule.

In implementation, the base station may determine, by using the first location, a time-frequency resource, excluding the time-frequency resource occupied by the first part of the uplink control information, from the time-frequency resources allocated to the UE, but not a time-frequency resource occupied by the second part of the uplink control information, then perform rate matching (the rate matching method is the same as the foregoing method), and determine, by using the data amount of each CB and the data amount of the data mapped by each resource unit, a first number of resource units of the time-frequency resource occupied by each CB, where in fact the first number is the same as the third number determined in step 203.

For any CB, the UE may determine a starting position of the time-frequency resource occupied by the CB by using the second time-frequency resource mapping rule and the first number corresponding to the CB. For example, the preset second time-frequency resource mapping rule is a frequency domain priority rule, the base station determines that there are 4 CBs, which are CB1, CB2, CB3, and CB4, and the corresponding first number is 10, 15, 20, and 18, the base station may count 10 resource units, which is the first CB (CB1), from the start position of the third time-frequency resource according to the frequency domain priority rule, the start position is the start position of the third time-frequency resource, then count 15 resource units from the 11 th resource unit, which is the second CB (CB2), the start position is the 11 th resource unit, then count 20 resource units from the 26 th resource unit, which is the third CB (CB3), the start position is the 26 th resource unit, then count 18 resource units from the 46 th resource unit, which is the fourth CB (CB4), and the start position is the 46 th resource unit. Thus, the starting position of the time frequency resource occupied by each CB is determined.

In step 211, the resource range of the time-frequency resource occupied by each CB is determined according to the starting position of the resource unit of the time-frequency resource occupied by each CB and the preset second time-frequency resource mapping rule, and each CB is recovered in the time-frequency resource obtained after the preset number of resource units are respectively cut off from the resource range of the time-frequency resource occupied by each CB, so as to obtain the uplink service data.

The preset second time-frequency resource mapping rule may be preset by a technician and stored in the base station, the time-frequency resource mapping rules used by the base station and the UE are corresponding, and if the time-frequency resource mapping rule used by the UE is a frequency domain priority mapping rule, the time-frequency resource mapping rule used by the base station is also a frequency domain priority mapping rule. The preset number of resource units may be used to map the second part of uplink control information, and in practice, not only the second part of uplink control information but also uplink service data may be mapped, where the preset number may generally be a number of resource units of time-frequency resources occupied by the second part of uplink control information, which is stored in the base station according to an experience value by a technician.

In implementation, after determining the starting position of the resource unit of the time-frequency resource occupied by each CB of the uplink service data, the base station may obtain a preset second time-frequency resource mapping rule, and then according to the preset second time-frequency resource mapping rule and the starting position of the resource unit of the time-frequency resource occupied by each CB, determine the resource range of the time-frequency resource occupied by each CB in the time-frequency resource allocated to the UE except the time-frequency resource occupied by the first part of the uplink control information (the resource range of the time-frequency resource occupied by the first CB is from the starting position of the first CB to the starting position corresponding to the second CB, the resource range of the time-frequency resource occupied by the second CB is from the starting position of the second CB to the starting position of the third CB, etc.), and then cut off a preset number of resource units in the time-frequency resource occupied by each CB, and obtaining the time frequency resources after the preset number of resource units are cut off, and recovering each CB from the time frequency resources to obtain each CB, namely the uplink service data.

It should be noted that, the above-mentioned resource range of the time-frequency resource occupied by each CB is not the actual time-frequency resource occupied by each CB, but the time-frequency resource occupied by each CB after the first rate matching is performed by the UE, and the time-frequency resource occupied by each CB after the first rate matching is subsequently allocated to a part for use by the second part of the uplink control information, so that a preset number of resource units need to be cut off from the resource range of the time-frequency resource occupied by each CB, and the time-frequency resource occupied by each CB after the second rate matching is used for mapping each CB in the uplink service data. In communication, due to the characteristics of channel coding, even if a small amount of coded information is lost, the base station can finish error-free decoding of the information before coding, so that even if the preset number of truncated resource units is more, accurate uplink service data can be obtained.

It should be noted that, the recovering of the uplink service data does not recover the first part of the uplink control information, so that the recovering of the uplink service data does not require the first part of the uplink control information.

Optionally, the first number of resource units of the time-frequency resource respectively occupied by each CB may be used to calculate a starting position of the time-frequency resource respectively occupied by each CB, and then each CB is recovered based on the starting position, and the corresponding processing in step 211 may be as follows:

determining the end position of each CB according to the initial position of the time-frequency resource occupied by each CB and a preset second time-frequency resource mapping rule, respectively carrying out interception processing or bit position zero processing on a preset number of resource units forward of the end position of each CB, and recovering each CB in the time-frequency resource subjected to interception processing or bit position zero processing to obtain uplink service data.

In the implementation, after determining the starting position of the resource unit of the time-frequency resource occupied by each CB, the base station determines, using the first position, the time-frequency resource allocated to the UE excluding only the time-frequency resource occupied by the first part of the uplink control information, that is, a third time-frequency resource, and then may obtain a preset second time-frequency resource mapping rule, where in the third time-frequency resource, the starting position of the third time-frequency resource is the starting position of the first CB, the ending position of the second CB is the ending position of the first CB, and the starting position of the third CB is the ending position of the second CB, so as to sequentially determine the ending positions of the time-frequency resources occupied by each CB, where it needs to be noted that the opposite process corresponding to step 203, the determined ending position of each CB is not actually the real ending position, but the ending position of each CB after the first rate matching in step 203, a small portion of resource units before the end position of each CB has a second portion of uplink control information mapped thereto. Then, interception processing or bit position zero processing can be performed forward from the end position of the time frequency resource occupied by each CB to obtain the time frequency resource after interception processing or bit position zero processing corresponding to each CB, and the CBs are recovered from the time frequency resources, so that the uplink service data uploaded by the UE can be obtained.

For example, the preset number is 2, after the end position is determined, 2 resource units may be intercepted from the end position forward for a first CB, then the time-frequency resources occupied by the first CB are determined from the 3 rd time-frequency resource to the 10 th time-frequency resource, and the CB is recovered from the time-frequency resources to obtain the first CB.

In some data encoding schemes, the encoded header information bits are more important than the encoded trailer information bits, and therefore, the encoded data is less affected by truncation of the trailer.

Optionally, in this embodiment of the present disclosure, a method for recovering the second part of uplink control information from the time-frequency resource is further provided, and corresponding processing may be as follows:

acquiring a first part of uplink control information from a first position; determining a second number of resource units of the time-frequency resources occupied by the second part of uplink control information according to the first part of uplink control information; and recovering the second part of uplink control information from the time frequency resources allocated to the UE according to the initial position and the second number of the time frequency resources occupied by each CB.

In implementation, if the data volume of each CB is the same, the base station may obtain the first part of uplink control information from the time-frequency resource at the first location, then determine the data volume of the second part of uplink control information by using the first part of uplink control information, and determine the second number of resource units of the occupied time-frequency resource by using the data volume. Then, the second number is divided by the number of CBs to obtain the number of resource units (which may be referred to as a fourth number) of the time-frequency resources respectively occupied by the divided uplink control information of the second part. And then, using the starting position of the second CB to count a fourth number of resource units forward to obtain a first part occupied by the first part of the uplink control information of the second part, and adopting the same method to obtain resource units occupied by the second part of the uplink control information except the last part of the uplink control information of the second part, and for the uplink control information of the last part, the base station can count the fourth number of resource units forward from the last of the time frequency resources distributed to the UE to obtain the last part of the uplink control information of the second part, so that the time frequency resources occupied by a plurality of parts of the uplink control information of the second part are obtained, and then the uplink control information of the second part is recovered from the time frequency resources.

If the data amount of each CB is different, the base station may obtain a first portion of uplink control information from the time-frequency resource at the first location, then determine, using the first portion of uplink control information, the data amount of a second portion of uplink control information and a third number of resource units occupied by each CB (the same as the processing in step 205), and determine, using the data amount, the second number of resource units of the occupied time-frequency resource. And then, determining the actual end position of each CB by using the second number of the resource units occupied by each CB, then calculating the end position from the actual end position of each CB to the base station for the first time, namely the time-frequency resource occupied by the second part of uplink control information, and recovering from the time-frequency resources to obtain the second part of uplink control information.

For the embodiment of the present disclosure, it should be noted that the calculation formula for calculating the number of the resource units of the time-frequency resource occupied by each CB may be the same as the calculation formula in LTE, or may also be a calculation formula for directly calculating the starting position of the resource unit of the time-frequency resource occupied by each CB by using the calculation formula in LTE.

In the disclosed embodiment, the UE determines the time-frequency resource allocated to the device, and the uplink service data and uplink control information to be transmitted, wherein the uplink control information at least includes a first part of uplink control information and a second part of uplink control information, determines a first position of the time-frequency resource occupied by the first part of uplink control information in the time-frequency resource allocated to the device according to a preset first system configuration and a preset first time-frequency resource mapping rule, determines an initial position of a resource unit of the time-frequency resource occupied by each CB according to a preset second time-frequency resource mapping rule and the time-frequency resource allocated to the device after only removing the time-frequency resource occupied by the first part of uplink control information, determines a first number of the resource units of the time-frequency resource occupied by the second part of uplink control information according to a preset second system configuration and the second part of uplink control information, determining a second number of resource units of the time-frequency resources occupied by each CB according to the time-frequency resources distributed to the equipment except the time-frequency resources occupied by the first part of the uplink control information and the second part of the uplink control information, determining a second position of the time-frequency resources occupied by each CB according to the initial position of the resource units of the time-frequency resources occupied by each CB, the second number of the resource units of the time-frequency resources occupied by each CB and a preset second time-frequency resource mapping principle, and mapping the first part of the uplink control information, the second part of the uplink control information and each CB to the time-frequency resources distributed to the equipment according to the first position and the second position for transmission. Thus, by adopting the method, the base station can determine the initial position of each CB based on the same calculation method and then recover the uplink service data, so that the base station recovers the uplink service data without depending on the content of the first part of the uplink information, the uplink service data can be recovered even if the recovery of the first part of the uplink control information fails, the recovery rate of the uplink service data can be improved, and the delay of recovering the uplink service data is lower because the uplink service data can be recovered without recovering the first part of the uplink control information.
