Description

Resource indication method, resource acquisition method, resource indication device, network side equipment and terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a resource indication method, a resource acquisition method, a resource indication device, a network side device, and a terminal.

Background

In the existing 4G or 5G system, only the uplink data channel adopts the transform precoding process, mainly because for the uplink, low Power consumption and low cost are important for the terminal, and directly using Orthogonal Frequency Division Multiplexing (OFDM) will generate a relatively large Peak to Average Power Ratio (PAPR), and the Power amplification efficiency is reduced. In order to suppress the above-mentioned influence, Discrete Fourier Transform-Spread OFDM (DFT-S-OFDM) is used for the uplink to reduce the terminal PAPR.

Although the improved scheme DFT-S-OFDM reduces PAPR and is used for transmission of an uplink data channel in a 4G or 5G system, the influence on Doppler spread is difficult to process as in the conventional OFDM, and in an actual system, Doppler spread is usually resisted forcibly or frequency offset correction is adopted by expanding subcarrier intervals, but the average value of multipath frequency offset can only be corrected. In addition, in the case of a large multipath delay, the CP overhead is large due to the need to ensure the length of the Cyclic Prefix (CP) by directly expanding the subcarrier spacing. And thirdly, the existing method only carries out transformation operation in one dimension of the frequency domain, and the diversity performance and the coverage performance of edge users further improve the space.

In order to address the above-mentioned shortcomings of the custom DFT-S-OFDM, an enhanced transform pre-processing scheme is proposed. However, in the enhanced transform preprocessing scheme, when there is data of multiple users for multiplexing transmission in the structure domain, if the existing resource indication manner is still used, for example, the base station notifies the users of the positions or the number of the time domain and the frequency domain resources, the user data may completely overlap in the time-frequency domain, and the receiving-end user may not demodulate in the time-frequency domain correctly.

alternatively, the first and second electrodes may be,

Example 1

The position of the data symbol set on the frequency domain is indirectly or implicitly indicated by the configuration of BWP, and the first indication information is dynamically indicated by DCI signaling. That is, the size in the frequency domain of the data symbol set is configured to be the same as the granularity of one BWP, the configuration is performed by the higher layer RRC signaling; the specific position of the first resource is notified through DCI signaling, and the position indicated by the first indication information is the specific position of the data symbol before the transformation preprocessing.

Example two

The location of the set of data symbols in the frequency domain is indirectly (implicitly) done by the configuration of the Resource Block Group (RBG), while the location of the first resource is dynamically indicated by DCI signaling. I.e. the size in the frequency domain of the data symbol set is configured to be the same as the granularity of one Resource Block Group (RBG), wherein the size of the RBG may be related to the size of the BWP, e.g. the size of the RBG in case of predefined different BWP sizes, and then configured through higher layer RRC signaling; the specific position of the first resource is notified through DCI signaling, and the position indicated by the first indication information is the specific position of the data symbol before the transformation preprocessing.

Example three

The positions of the first resource and the data symbol set are dynamically notified through DCI signaling, the position of the data symbol set is the position of a frequency domain and/or a time domain, and the position of the first resource is the position of a data symbol before transformation preprocessing.

Example four

The positions of the first resource and the data symbol set are dynamically notified through DCI signaling, and the positions of the first resource and the data symbol set are the positions of the data symbols before the transformation preprocessing, but when the terminal performs processing, the terminal side can indirectly derive the position of the data symbol set in the time-frequency domain according to the positions of the data symbols before the transformation preprocessing of the data symbol set.

In the above embodiments of the present invention, the first indication information is used to indicate an absolute position of the first resource or the first data symbol set, or is used to indicate a number of resources of the first resource or a number of symbols of the first data symbol set, or is used to indicate a relative position of the first resource with respect to a first target resource, or is used to indicate a relative position of the first data symbol set with respect to a first target data symbol set.

In the above embodiment of the present invention, the second indication information is used to indicate an absolute position of the second resource or the second data symbol set, or is used to indicate a resource number of the second resource or a symbol number of the second data symbol set, or is used to indicate a relative position of the second resource with respect to a second target resource, or is used to indicate a relative position of the second data symbol set with respect to a second target data symbol set.

Wherein, in case the first indication information indicates an absolute position of the first resource or the first set of data symbols and the second indication information indicates a relative position of the second set of data symbols or the second resource, the relative position of the second set of data symbols or the second resource may preferably be a relative position with respect to the absolute position of the first resource; in the case where the second indication information indicates an absolute position of the second set of data symbols or the second resource, and the first indication information indicates a relative position of the first resource or the first set of data symbols, the relative position indicated by the first indication information may preferably be a relative position with respect to the absolute position of the second set of data symbols or the second resource; and in the case that the first indication information indicates a relative position and the second indication information indicates a relative position, the relative position may be relative to a predetermined resource, or the terminal may indirectly obtain an absolute position indicated by at least one of the first indication information and the second indication information according to another manner.

In summary, the network side device indicates, through the first indication information, the first data symbol set allocated to the first terminal or the first resource occupied by the first data symbol set, indicates, through the second indication information, the second resource occupied by the data symbol set after the inverse transformation preprocessing is performed by the first terminal, or indicates, through the second indication information, the second data symbol set before the inverse transformation preprocessing is performed by the first terminal, so that the terminal can correctly identify the position of the data of the terminal.

As shown in fig. 2, an embodiment of the present invention further provides a resource obtaining method, applied to a first terminal, including:

step 21, receiving first indication information and second indication information sent by network side equipment; the first indication information is used for indicating a first data symbol set allocated by a network side device for the first terminal or a first resource occupied by the first data symbol set; the second indication information is used for indicating a second resource occupied by the data symbol set after inverse transformation preprocessing of the first terminal; or the second indication information is used for indicating the second data symbol set before the inverse transformation preprocessing is carried out by the first terminal.

In this step, the inverse transform preprocessing may include: inverse transform precoding (e.g., inverse unitary transform), etc., and is not particularly limited herein.

And step 22, acquiring the resource of the first terminal according to the first indication information and the second indication information.

Considering whether the receiving end has performed inverse resource mapping processing, the first indication information and the second indication information may indicate the data symbol set, or indicate the resources occupied by the data symbols. For example, the second indication information indicates the resource information after the inverse transform preprocessing, and the first indication information indicates the first data symbol set information before the inverse transform preprocessing, as shown in fig. 3.

Note that the different indications of the first indication information and the second indication information include at least four combinations:

in a first manner, in a case that the first indication information indicates a first data symbol set allocated by the network side device to the first terminal, and the second indication information indicates a second resource occupied by the data symbol set after inverse transformation preprocessing performed by the first terminal, the step 22 includes:

performing inverse transformation preprocessing on the first data symbol set indicated by the first indication information to obtain a resource position (the resource position is a relative resource position) corresponding to the first data symbol set;

the absolute position of the resource of the first terminal can be determined according to the resource position corresponding to the first data symbol set and the position of the second resource indicated by the second indication information (the position of the second resource is directly indicated by the network side, and is an absolute position).

In a second mode, when the first indication information indicates a first data symbol set allocated by the network side device to the first terminal, and the second indication information indicates a second data symbol set before inverse transformation preprocessing is performed by the first terminal, the step 22 includes:

performing inverse transformation preprocessing on the second data symbol set indicated by the second indication information to obtain a resource position (the resource position is a relative resource position) corresponding to the second data symbol set;

according to the resource position corresponding to the first data symbol set, the resource position corresponding to the second data symbol set and an absolute reference resource position, the absolute position of the resource of the first terminal can be determined.

It should be noted that the absolute reference resource location may be indicated to the first terminal through a third indication information, or may reuse an existing absolute resource location, or may be determined through a predetermined convention, a predetermined configuration, and the like, which is not limited herein.

In a third mode, when the first indication information indicates a first resource occupied by a first data symbol set allocated by the network side device to the first terminal, and the second indication information indicates a second resource occupied by a data symbol set subjected to inverse transform preprocessing by the first terminal, since both the first indication information and the second indication information indicate absolute positions of the resources subjected to inverse transform preprocessing, the step 22 includes:

according to the position of the first resource indicated by the first indication information and the position of the second resource indicated by the second indication information, the absolute position of the resource of the first terminal can be determined.

In a fourth mode, in the case that the first indication information indicates a first resource occupied by a first data symbol set allocated by the network side device to the first terminal, and the second indication information indicates a second data symbol set before the first terminal performs inverse transformation preprocessing, the step 22 includes:

the absolute position of the resource of the first terminal can be determined according to the resource position corresponding to the second data symbol set and the position of the first resource indicated by the first indication information (the position of the first resource is directly indicated by the network side, and is an absolute position).

As another alternative, the second set of data symbols comprises:

Optionally, in the foregoing embodiment of the present invention, the first resource and/or the second resource includes at least one of the following resources:

The first DCI and the second DCI may be the same DCI or different DCIs; the first RRC signaling and the second RRC signaling may be the same RRC signaling or different RRC signaling; and is not particularly limited herein.

alternatively, the first and second electrodes may be,

In other words, the first indication information may indicate an absolute position of the first resource, and may also indicate a relative position of the first resource; the second indication information may indicate an absolute position of the set of data symbols, and may also indicate a relative position of the set of data symbols.

In summary, in the embodiment of the present invention, the network side device indicates, through the first indication information, the first data symbol set allocated to the first terminal or the first resource occupied by the first data symbol set, indicates, through the second indication information, the second resource occupied by the data symbol set after the inverse transformation preprocessing is performed by the first terminal, or indicates, through the second indication information, the second data symbol set before the inverse transformation preprocessing is performed by the first terminal, so that the terminal can correctly identify the position of the data of the terminal.

Example five

As shown in fig. 4, x1 denotes the time domain, and x2 denotes the frequency domain; after the data of a plurality of multiplexing users orthogonal in a construction domain are subjected to transformation preprocessing operation, the data are overlapped in a time-frequency domain, so that a terminal cannot identify the position of the data in the time-frequency domain; therefore, in the embodiment of the present invention, the network side device not only notifies the target user (for example, terminal 1) of the position of the own data in the configuration domain (i.e., information of the first resource) before performing the transform domain processing, but also needs to know the size or the position of the total resource for multiplexing transmission with the terminal in order that the terminal can correctly obtain the position information of the own data, where the total resource is the resource occupied by the data actually subjected to the transform preprocessing by the target user (for example, terminal 1) (i.e., information of the first data symbol set), where the first data symbol set includes both the data symbol of the target user and the data symbol of another user (for example, terminal 2) performing the transform transmission with the target user.
