Detailed Description

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

For ease of understanding, application scenarios of embodiments of the present disclosure will be described before explaining the embodiments of the present disclosure in detail.

In a communication system, a base station may be accessed by a non-orthogonal multiple access technique before a user equipment transmits uplink data to the base station. In the non-orthogonal multiple access technology, a base station allocates one transmission resource to a plurality of user equipments for use, and the transmission resource may include a time-frequency resource, a multiplexing factor, a reference signal port, and the like. In this case, multiple user equipments may select the same transmission resource for the same channel (e.g., control channel, data channel). At present, the base station broadcasts a resource information base for transmitting resource information of a control channel and a resource information base for transmitting resource information of a data channel respectively, after receiving the two resource information bases, the user equipment can determine the transmission resource of the control channel and the transmission resource of the data channel according to the two resource information bases respectively, and then the user equipment can transmit uplink data to the base station through the determined transmission resource.

Since the ue determines the transmission resources of the control channel according to the resource information base of the control channel transmission resource information, and determines the transmission resources of the data channel according to the resource information base of the data channel transmission resource information, that is, the ue independently selects the control channel transmission resources and the data channel transmission resources. In this case, the first user equipments selecting the same control channel transmission resource may collide with the control channel, and the second user equipments selecting the same data channel transmission resource may collide with the data channel, so that the two collisions between the same control channel transmission resource and the same data channel transmission resource may affect the transmission of uplink data between the first user equipments and the second user equipments, thereby causing a scattered collision.

For example, there are four user equipments, which respectively select control channel transmission resource information and data channel transmission resource information as shown in table 1 below. Because the control channel transmission resource selected by the user equipment identified by the user equipment identification 1 is the same as the control channel transmission resource selected by the user equipment identified by the user equipment identification 2, and the data channel transmission resource selected by the user equipment identified by the user equipment identification 3 is the same as the data channel transmission resource selected by the user equipment identified by the user equipment identification 4, the user equipment identified by the user equipment identification 1 collides with the user equipment identified by the user equipment identification 2 by the control channel, and the user equipment identified by the user equipment identification 3 collides with the user equipment identified by the user equipment identification 4 by the data channel, at the moment, the transmission of uplink data of four user equipment is influenced due to the two collisions of the same control channel transmission resource and the same data channel transmission resource, and the scattered collision is caused.

User equipment identification	Control channel transmission resource information	Data channel transmission resource information
			User equipment identity 1	Control channel transmission resource information 1	Data channel transmission resource information 1

			User equipment identity 3	Control channel transmission resource information 2	Data channel transmission resource information 3

For this reason, the embodiment of the present disclosure provides an uplink data transmission method to reduce the probability of collision.

Fig. 1 is a flow chart illustrating an uplink data transmission method according to an exemplary embodiment, which includes the following steps, as shown in fig. 1.

In step 101, a resource information base transmitted by a base station is received, where the resource information base includes a plurality of first channel transmission resource information and a plurality of second channel transmission resource information.

In step 102, first target channel transmission resource information is acquired from the plurality of first channel transmission resource information, and second target channel transmission resource information corresponding to the first target channel transmission resource information is acquired from the plurality of second channel transmission resource information.

In step 103, uplink data is transmitted to the base station through the resources corresponding to the first target channel transmission resource information and the resources corresponding to the second target channel transmission resource information.

acquiring first target channel transmission resource information from the plurality of first channel transmission resource information, and acquiring second target channel transmission resource information corresponding to the first target channel transmission resource information from the plurality of second channel transmission resource information, includes:

selecting one first channel transmission resource information from the plurality of first channel transmission resource information as first target channel transmission resource information;

second channel transmission resource information corresponding to the first target channel transmission resource information is acquired from the plurality of second channel transmission resource information as second target channel transmission resource information.

second channel transmission resource information identified by the second information identification is acquired from the plurality of second channel transmission resource information as second target channel transmission resource information.

Optionally, the first preset rule is a rule for generating the second information identifier according to at least one of the first information identifier, the number of second channel transmission resource information, the identifier of the radio frame to be used currently, and the identifier of the subframe to be used currently.

acquiring first channel transmission resource information identified by a first information identifier from the plurality of first channel transmission resource information as first target channel transmission resource information;

Optionally, the second preset rule is a rule for generating an information identifier according to at least one of a user equipment identifier, a number of channel transmission resource information, an identifier of a radio frame to be currently used, and an identifier of a subframe to be currently used.

Optionally, the resource information base is broadcast by the base station.

All the above optional technical solutions may be combined according to any choice to form an optional embodiment of the disclosure, which is not described in detail herein.

Fig. 2 is a flow chart illustrating an uplink data transmission method according to an exemplary embodiment. Embodiments of the present disclosure will be discussed in conjunction with fig. 2 in the description of the embodiment shown in fig. 1. The method is applied to the user equipment and comprises the following steps.

In step 201, a resource information base sent by a base station is received, where the resource information base includes a plurality of first channel transmission resource information and a plurality of second channel transmission resource information.

It should be noted that, the resource information base may be broadcast by the base station, and resources corresponding to the plurality of first channel transmission resource information and resources corresponding to the plurality of second channel transmission resource information included in the resource information base may be used for transmitting uplink data.

In addition, the first channel transmission resource information may be control channel transmission resource information, the second channel transmission resource information may be data channel transmission resource information, that is, the first channel may be a control channel, and the second channel may be a data channel; alternatively, the first channel transmission resource information may be data channel transmission resource information, and the second channel transmission resource information may be control channel transmission resource information, i.e., the first channel may be a data channel, and the second channel may be a control channel. The resources corresponding to the control channel transmission resource information can be used for transmitting control data in uplink data, such as user equipment identification, modulation coding information of the data and the like, and the resources corresponding to the data channel transmission resource information can be used for transmitting service data in the uplink data.

Furthermore, the first channel transmission resource information and the second channel transmission resource information may each include transmission resource information such as T (time), F (frequency), signature (multiplexing factor), RS (Reference Signal port), and the like. Signature may be a power class, an interleaver, a spreading code, etc., which may enable distinguishing between different user devices when non-orthogonal multiple access is performed. For example, the first channel transmission resource information may be t1_ C, F1_ C, signature1_ C, RS1 _1_c, and the second channel transmission resource information may be t1_d, f1_d, signalu1_d, and RS1_d.

In step 202, first target channel transmission resource information is acquired from the plurality of first channel transmission resource information, and second target channel transmission resource information corresponding to the first target channel transmission resource information is acquired from the plurality of second channel transmission resource information.

It should be noted that, first, the first target channel transmission resource information is acquired from the plurality of first channel transmission resource information, and then the second target channel transmission resource information corresponding to the first target channel transmission resource information is acquired from the plurality of second channel transmission resource information, so that the acquired first target channel transmission resource information corresponds to the second target channel transmission resource information, in other words, after the first target channel transmission resource information is selected, the second target channel transmission resource information corresponding to the first target channel transmission resource information is necessarily selected. In this case, if the plurality of user equipments each select the first target channel transmission resource information, the plurality of user equipments must each select the second target channel transmission resource information corresponding to the first target channel transmission resource information, so that due to the two collisions of the same first channel transmission resource and the same second channel transmission resource, only the transmission of uplink data of the plurality of user equipments will be affected, that is, the embodiments of the present disclosure may integrate the first channel collision and the second channel collision that may occur, thereby avoiding the scattered collision and effectively reducing the number of user equipments affected by the collision.

When step 202 is implemented, the first target channel transmission resource information and the second target channel transmission resource information may be jointly selected; or, the transmission resource information of the second target channel to be selected can be determined according to the transmission resource information of the first target channel which is selected; alternatively, the first target channel transmission resource information and the second target channel transmission resource information may be selected according to the same rule. That is, step 202 may be implemented by the following three implementations.

The first implementation mode: when the plurality of first channel transmission resource information and the plurality of second channel transmission resource information included in the resource information base are in one-to-one correspondence, one first channel transmission resource information may be selected from the plurality of first channel transmission resource information as first target channel transmission resource information, and second channel transmission resource information corresponding to the first target channel transmission resource information may be acquired from the plurality of second channel transmission resource information as second target channel transmission resource information.

It should be noted that, in this implementation manner, since the plurality of first channel transmission resource information and the plurality of second channel transmission resource information included in the resource information base are in one-to-one correspondence, the corresponding one of the first channel transmission resource information and the corresponding one of the second channel transmission resource information are directly selected to be used as the first target channel transmission resource information and the second target channel transmission resource information respectively, the implementation manner is simple and convenient, and the processing resources can be saved.

In addition, in this implementation manner, the base station may pre-establish a correspondence between the first channel transmission resource information and the second channel transmission resource information, so that the plurality of first channel transmission resource information and the plurality of second channel transmission resource information correspond one to one, and then carry the correspondence between the first channel transmission resource information and the second channel transmission resource information in the resource information base and send the correspondence to the user equipment. In this case, when second channel transmission resource information corresponding to the first target channel transmission resource information is acquired from the plurality of second channel transmission resource information as second target channel transmission resource information, the second channel transmission resource information corresponding to the first target channel transmission resource information may be acquired as second target channel transmission resource information directly from the correspondence between the first channel transmission resource information and the second channel transmission resource information included in the resource information base.

For example, if the first channel transmission resource information selected from the plurality of first channel transmission resource information is t1_ C, F1_ C, signature1_ C, RS1 _1_c, that is, if the first target transmission resource information is t1_ C, F1_ C, signature1_ C, RS1 _1_c, the second channel transmission resource information corresponding to the first target transmission resource information may be obtained from the correspondence relationship between the first channel transmission resource information and the second channel transmission resource information as shown in table 2 below, and at this time, t1_d, f1_d, signalu1_d, and RSs 1_d may be determined as the second target channel transmission resource information.

TABLE 2

First channel transmission resource information	Second channel transmission resource information
		T1_C、F1_C、Signature1_C、RS1_C	T1_d、F1_d、Signature1_d、RS1_d
T1_C、F1_C、Signature2_C、RS2_C	T1_d、F1_d、Signature2_d、RS2_d

		T1_C、F2_C、Signature2_C、RS2_C	T1_d、F2_d、Signature1_d、RS1_d
……	……

It should be noted that, in the embodiments of the present disclosure, only the correspondence between the first channel transmission resource information and the second channel transmission resource information shown in the above table 2 is described as an example, and the above table 2 does not limit the embodiments of the present disclosure.

Wherein, selecting one first channel transmission resource information from the plurality of first channel transmission resource information as the first target channel transmission resource information may be implemented in the following manner 1 or manner 2:

mode 1: one first channel transmission resource information is randomly selected from the plurality of first channel transmission resource information as first target channel transmission resource information.

Mode 2: when the plurality of first channel transmission resource information all have the information identification, the first information identification is determined according to a third preset rule, and the first channel transmission resource information identified by the first information identification is obtained from the plurality of first channel transmission resource information to serve as first target channel transmission resource information.

It should be noted that, the third preset rule is a rule for generating the first information identifier, and the third preset rule may be preset and may be the same for each ue, for example, the third preset rule may be a rule for generating the first information identifier according to at least one of the ue identifier, the number of the first channel transmission resource information, the identifier of the radio frame to be used currently, the identifier of the subframe to be used currently, and the like.

For example, the third preset rule is: the number of first information identifiers= (user equipment identifier+identifier of subframe to be currently used) mod first channel transmission resource information, the user equipment identifier is 4, the current subframe to be used is 3 rd subframe in the radio frame, the number of first channel transmission resource information is 5, at this time, according to a third preset rule, the determined first information identifier is (4+3) mod 5=2, at this time, the first channel transmission resource information identified by the information identifier of 2 may be obtained from a plurality of first channel transmission resource information shown in table 3 below to be t1_ C, F1_ C, signature2_ C, RS2_c, and t1_ C, F1_ C, signature2_ C, RS2_c is determined as the first target channel transmission resource information.

TABLE 3 Table 3

2	T1_C、F1_C、Signature2_C、RS2_C

4	T1_C、F2_C、Signature1_C、RS1_C
		5	T1_C、F2_C、Signature2_C、RS2_C

The embodiment of the present disclosure will be described by taking the first channel transmission resource information shown in table 3 as an example, and table 3 does not limit the embodiment of the present disclosure.

It should be noted that the first implementation manner is to directly select a first channel transmission resource information and a second channel transmission resource information corresponding to the first channel transmission resource information. In this case, in order to simplify the selection operation, any one of the plurality of first channel transmission resource information and the plurality of second channel transmission resource information may have one joint information identity, and in this case, the plurality of first channel transmission resource information and the plurality of second channel transmission resource information may have a plurality of joint information identities in total. In this case, the first implementation may be: selecting one joint information identifier from the plurality of joint information identifiers as a third information identifier, or determining the third information identifier according to a fourth preset rule; and acquiring corresponding first channel transmission resource information and second channel transmission resource information identified by a third information identifier from the plurality of first channel transmission resource information and the plurality of second channel transmission resource information, determining the acquired first channel transmission resource information as first target channel transmission resource information, and determining the acquired second channel transmission resource information as second target channel transmission resource information.

It should be noted that, the fourth preset rule is a rule for generating the third information identifier, and the fourth preset rule may be preset and may be the same for each ue, for example, the fourth preset rule may be a rule for generating the third information identifier according to at least one of the ue identifier, the number of the first channel transmission resource information or the number of the second channel transmission resource information, the identifier of the radio frame to be used currently, the identifier of the subframe to be used currently, and the like.

For example, if one joint information identifier is selected as the third information identifier from among a plurality of joint information identifiers stored in the correspondence between the first channel transmission resource information and the second channel transmission resource information as shown in table 4 below, and assuming that the third information identifier is 1, a pair of corresponding first channel transmission resource information and second channel transmission resource information identified as 1 information identifiers may be acquired from the correspondence between the first channel transmission resource information and the second channel transmission resource information as shown in table 4 below, and t1_ C, F1_ C, signature1_ C, RS1_c and t1_d, f1_d, signalure 1_d, and RS1_d, respectively, at this time t1_ C, F1_ C, signature1_ C, RS1_c may be determined as the first target channel transmission resource information, and t1_d, f1_d, signalure 1_d, and RS1_d may be determined as the second target channel transmission resource information.

TABLE 4 Table 4

The embodiments of the present disclosure will be described by taking the correspondence between the first channel transmission resource information and the second channel transmission resource information shown in table 4 as an example, and table 4 does not limit the embodiments of the present disclosure.

For another example, the fourth preset rule may be: the third information identifier= (user equipment identifier+identifier of subframe to be currently used) mod the number of first channel transmission resource information, the user equipment identifier is 4, what is currently to be used is 3 rd subframe in the radio frame, the number of first channel transmission resource information is 5, at this time, according to a fourth preset rule, the determined third information identifier is (4+3) mod 5=2, then the corresponding first channel transmission resource information and second channel transmission resource information identified by the information identifier of 2 can be obtained from the correspondence relationship between the first channel transmission resource information and the second channel transmission resource information shown in the above table 4, and are respectively t1_ C, F1_ C, signature2_ C, RS2_c and t1_d, f1_d, signalu2_d, and RS2_d, at this time, t1_ C, F1_ C, signature2_ C, RS2_c can be determined as first target channel transmission resource information, and t1_d, f1_d, RS2_ C, RS _c can be determined as second target channel transmission resource information.

The second implementation mode: when the first channel transmission resource information and the second channel transmission resource information have information identifiers, selecting one first channel transmission resource information from the first channel transmission resource information as first target channel transmission resource information, determining the information identifier of the first target channel transmission resource information as first information identifier, then determining a second information identifier according to the first information identifier and a first preset rule, and acquiring the second channel transmission resource information identified by the second information identifier from the second channel transmission resource information as second target channel transmission resource information.

It should be noted that, in this implementation manner, first a first channel transmission resource information is selected, and then a second channel transmission resource information is selected according to the information identifier of the first channel transmission resource information, so that the selected first channel transmission resource information and the selected second channel transmission resource information can be ensured to be corresponding, and the operation is simple. In this case, the base station only needs to set corresponding information identifiers for the plurality of first channel transmission resource information and the plurality of second channel transmission resource information, and does not need to perform other complex operations, so that the processing resources of the base station can be saved.

In addition, the first preset rule is a rule for generating the second information identifier, and the first preset rule may be preset and may be the same for each user equipment, for example, the first preset rule may be a rule for generating the second information identifier according to at least one of the first information identifier, the number of second channel transmission resource information, the identifier of the radio frame to be used currently, the identifier of the subframe to be used currently, and the like.

For example, the first preset rule may be: second information identification= (first information identification+identification of subframe to be currently used) mod second channel transmission resource information, the first information identification is 1, 3 rd subframe in radio frame is to be currently used, the number of second channel transmission resource information is 5, at this time, according to a first preset rule, the determined second information identification is (1+3) mod 5=4, then the second channel transmission resource information identified by the information identification of 4 is obtained from a plurality of pieces of second channel transmission resource information shown in table 5 below as t1_d, f1_d, signalu4_ C, RS4_d, t1_d, f1_d, signalu4_ C, RS4_d are taken as second target channel transmission resource information.

TABLE 5

Information identification	Second channel transmission resource information
		1	T1_d、F1_d、Signature1_d、RS1_d
2	T1_d、F1_d、Signature2_d、RS2_d

The embodiment of the present disclosure will be described by taking the plurality of pieces of second channel transmission resource information shown in table 5 as an example, and table 5 does not limit the embodiment of the present disclosure.

In addition, the implementation process of selecting one first channel transmission resource information from the plurality of first channel transmission resource information as the first target channel transmission resource information is the same as the implementation process of selecting one first channel transmission resource information from the plurality of first channel transmission resource information as the first target channel transmission resource information in the first implementation manner, and is not described herein again.

Third implementation: when the plurality of first channel transmission resource information and the plurality of second channel transmission resource information both have information identifications, determining a first information identification and a second information identification according to a second preset rule, then acquiring the first channel transmission resource information identified by the first information identification from the plurality of first channel transmission resource information as first target channel transmission resource information, and acquiring the second channel transmission resource information identified by the second information identification from the plurality of second channel transmission resource information as second target channel transmission resource information.

It should be noted that, in this implementation manner, the first channel transmission resource information and the second channel transmission resource information are selected according to the same rule, so that the selected first channel transmission resource information and the selected second channel transmission resource information can be ensured to be corresponding, and the operation is simple. In this case, the base station only needs to set corresponding information identifiers for the plurality of first channel transmission resource information and the plurality of second channel transmission resource information, and does not need to perform other complex operations, so that the processing resources of the base station can be saved.

In addition, the second preset rule is a rule for generating an information identifier, and the second preset rule may be preset and may be the same for each ue, for example, the second preset rule may be a rule for generating an information identifier according to at least one of a ue identifier, the number of channel transmission resource information, the identifier of a radio frame to be used currently, the identifier of a subframe to be used currently, and the like.

For example, when the first information identifier is determined according to the second preset rule, the second preset rule may be: the number of first information identifiers= (user equipment identifier+identifier of subframe to be currently used) mod first channel transmission resource information, the number of user equipment identifier is 4, the number of first channel transmission resource information is 5 in the 3 rd subframe of the radio frame to be currently used, at this time, according to the second preset rule, the determined first information identifier is (4+3) mod 5=2, then the first channel transmission resource information identified by the information identifier of 2 may be obtained from the plurality of first channel transmission resource information shown in table 3 and is t1_ C, F1_ C, signature2_ C, RS2_c, and t1_ C, F1_ C, signature2_ C, RS2_c is taken as the first target channel transmission resource information.

For another example, when the second information identifier is determined according to a second preset rule, the second preset rule may be: the second information identifier= (user equipment identifier+identifier of subframe to be currently used) mod second channel transmission resource information, the user equipment identifier is 4, the current subframe to be used is 3 rd subframe in the radio frame, the number of the second channel transmission resource information is 5, at this time, according to a second preset rule, the determined second information identifier is (4+3) mod 5=2, and then the second channel transmission resource information identified by the information identifier of 2 can be obtained from the plurality of second channel transmission resource information shown in table 5 and is t1_d, f1_d, signalre2_d, and RS2_d, and t1_d, f1_d, signalre2_d, and RS2_d are taken as second target channel transmission resource information.

In step 203, uplink data is transmitted to the base station through the resources corresponding to the first target channel transmission resource information and the resources corresponding to the second target channel transmission resource information.

In this case, the resource corresponding to the transmission resource information of the first target channel is used as the transmission resource of the first channel, the resource corresponding to the transmission resource information of the second target channel is used as the transmission resource of the second channel, then the uplink data carried by the first channel is transmitted through the transmission resource of the first channel, and the uplink data carried by the second channel is transmitted through the transmission resource of the second channel.

It should be noted that, since the first target channel transmission resource information determined in the steps 201 to 202 corresponds to the second target channel transmission resource information, if the first target channel transmission resource information determined by the plurality of user equipments is the same, the second target channel transmission resource information determined by the plurality of user equipments is necessarily the same, at this time, only the transmission of uplink data of the plurality of user equipments will be affected due to the two collisions occurring between the same first channel transmission resource and the same second channel transmission resource, so that the possible first channel collision and second channel collision are concentrated together, avoiding the scattered collision, and further effectively reducing the number of user equipments affected by the collision.
