Description

Transmission format determining method, device, base station, terminal and storage medium

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a method, an apparatus, a base station, a terminal, and a storage medium for determining a transmission format.

Background

The wireless communication system provides a plurality of resources for interaction between the terminal and the base station, each resource comprises a plurality of sub-resources with fixed quantity, and when the transmission formats of the sub-resources are different, the data transmission modes of the terminal and the base station are also different. Therefore, before the terminal and the base station perform data transmission, the transmission format of each sub-resource needs to be determined.

Taking resources as time slots and sub-resources as symbols as examples, a time slot comprises a plurality of symbols with fixed quantity, the base station determines the transmission format of each symbol in the time slot by taking a time slot as a unit, and sends indication information to the terminal, wherein the indication information is used for indicating the transmission format of each symbol in the time slot. And the terminal receives the indication information, determines the transmission format of each symbol in the time slot according to the indication information, and performs data transmission with the base station based on the determined transmission format.

The process of sending the indication information can be performed through the authorized frequency band, and with the rapid increase of mobile data, the available authorized frequency band gradually becomes saturated, and the problem of frequency band shortage occurs at present. In order to solve the problem, the base station can also perform data interaction with the terminal through an unauthorized frequency band. In the unlicensed frequency band, the base station also needs to send indication information to the terminal. However, as shown in fig. 1, if the base station wants to send the indication information to the terminal, it first detects whether the unlicensed frequency band is idle, and when detecting that the unlicensed frequency band is idle, it occupies the resource set in the unlicensed frequency band. If the starting position of the resource set is not located at the starting position of the first resource in the resource set, or the ending position of the resource set is not located at the ending position of the last resource in the resource set, this may result in an incomplete resource (shaded portion) being present in the resource set. Therefore, it is desirable to provide a method for determining the transmission format of the sub-resource in the incomplete resource.

Fig. 5 is a flowchart illustrating a method for determining a transport format according to an exemplary embodiment, where interaction subjects are a base station and a terminal, and as shown in fig. 5, the method includes the following steps:

in step 501, the base station determines a specified number and a specified location identity.

Generally, a base station can configure a licensed frequency band, and the base station and a terminal communicate through the licensed frequency band. In order to solve the problem of frequency band shortage, the base station can also be configured with an unauthorized frequency band at present, and the base station and the terminal can communicate through the unauthorized frequency band. Wherein the authorized frequency band is different from the unauthorized frequency band.

When the base station communicates with the terminal through the unlicensed frequency band, the base station needs to occupy a resource set in the unlicensed frequency band first, and then can communicate with the terminal through the resource set. The resource set is located in the unlicensed frequency band, and the length of the resource set is a first preset length.

In one possible implementation, with respect to a first preset length of the set of resources: the resource set includes time domain resources and/or frequency domain resources, and taking the resource set as the time domain resources as an example for explanation, the duration of the base station occupying the unauthorized frequency band is determined, so that the first preset length of the occupied resource set is determined and is equal to the duration of the base station occupying the unauthorized frequency band this time.

In another possible implementation, the determination regarding the set of resources is: when the base station successfully occupies the unauthorized frequency band, the time when the base station successfully occupies is determined as the initial position of the resource set, the position which is located behind the initial position and has the first preset length is determined as the end position of the resource set, and the resource set can be determined according to the initial position and the end position of the resource set.

The resource set includes a plurality of resources including at least one incomplete resource. This is due to: the starting position of the resource set is not fixed, and is likely to be located in the middle of a certain resource, resulting in incomplete first resource of the resource set. And the length of the resource set is the first preset length, the ending position of the resource set may be located in the middle of a certain resource, which may result in incomplete last resource of the resource set, or may also result in incomplete certain resource in the resource set due to other reasons.

And the middle position of each resource is a position except the starting position and the ending position in the resource. The complete resource refers to a resource with a length of a second preset length, and the incomplete resource refers to a resource with a length less than a second preset duration. That is, when the length of a certain resource is smaller than the second preset length, the resource is determined to be an incomplete resource, and when the length of a certain resource is equal to the second preset length, the resource is determined to be a complete resource.

In addition, the second preset length is smaller than the first preset length to ensure that the resource set can include a plurality of resources.

In addition, each resource comprises at least one sub-resource, the length of each sub-resource is a third preset length, and the third preset length is smaller than the second preset length. For example, one resource may be one slot, one sub-resource may be one symbol, and one slot includes a fixed number of symbols.

Correspondingly, the number of the sub-resources in one complete resource is a preset number, and the preset number is a ratio of the second preset length to the third preset length. And the quantity of the sub-resources in one incomplete resource is a specified quantity, and the specified quantity is smaller than a preset quantity. For example, the preset number may be 7, 14 or other numbers, may be configured by the base station, or may be determined by a protocol between the terminal and the base station or in other manners.

In the embodiment of the present disclosure, if the base station wants to communicate with the terminal through the resource set, it needs to determine the transmission format of each sub-resource in the resource set first, and perform data transmission according to the transmission format of each sub-resource.

To this end, the base station determines a specified number and a specified location identity. The specified number is the number of sub-resources in the incomplete resource in the resource set, for example, the specified number may be 5, 6, 7 or other values, and may be determined according to the length of the incomplete resource and the third preset time duration of the sub-resources.

And the specified position identification is used for representing the position of the incomplete resource in the resource set, and the position of the incomplete resource in the resource set can be determined according to the specified position identification. And if the plurality of resources in the resource set are arranged in sequence, the designated position identification is used for indicating the position of the incomplete resource in the plurality of resources arranged in sequence. For example, each resource in the resource set is assigned a sequence number, and the sequence of multiple resources can be determined according to the sequence number of each resource, so that the specified location identifier may be a sequence number of an incomplete resource.

In a possible implementation manner, when the base station sends the control signaling through the unlicensed frequency band, the incomplete resources in the resource set may be determined through the following steps 5011 and 5012, and the specified number and the specified location identifier may also be determined.

5011. When the starting position of the resource set is the middle position of the first resource, determining that the resource behind the starting position in the first resource is an incomplete resource, and identifying the designated position of the incomplete resource as a first position identifier.

Since the starting position of the resource set is in the middle of the first resource, the base station and the terminal may communicate on the resource after the starting position, the resource between the starting position of the first resource and the starting position of the resource set is an unavailable resource, and the resource after the starting position of the resource set in the first resource is an available resource. That is, the resource located after the start position of the resource set in the first resource is an incomplete resource, or the resource between the start position of the resource set and the end position of the first resource is an incomplete resource, and the base station determines the incomplete resource and determines the number of sub-resources in the incomplete resource as the designated number.

In this case, it may be directly determined that the first resource in the resource set is an incomplete resource, and thus the designated location identifier is determined as the first location identifier. The first location identifier indicates that the incomplete resource is located at the first location of the resource set, and may be 1 or 0 or other identifiers.

5012. And when the end position of the resource set is the middle position of the second resource, determining that the resource before the end position in the second resource is an incomplete resource, and identifying the designated position of the incomplete resource as a second position identifier.

Since the ending position of the resource set is in the middle position of the second resource, the base station and the terminal can only communicate on the resource before the ending position, the position of the second resource after the middle position of the second resource is an unavailable resource, and the resource between the starting position of the second resource and the ending position of the resource set is an available resource. That is, the resource located before the end position of the resource set in the second resource is an incomplete resource, or the resource between the start position of the second resource and the end position of the resource set is an incomplete resource, and the base station determines the incomplete resource and determines the number of the sub-resources in the incomplete resource as the designated number.

In this case, it can be directly determined that the last resource in the resource set is an incomplete resource, and thus the designated location identifier is determined as the second location identifier. Wherein the second location identifier indicates that the incomplete resource is located at the last location of the resource set, and the second location identifier is different from the first location identifier and may be 10, 11 or other identifiers.

In step 502, the base station sends a control signaling to the terminal through the unlicensed frequency band, where the control signaling includes a designated number and a designated location identifier.

In one possible implementation, the unlicensed frequency band may be a GC-PDCCH (multicast-Physical Downlink Control Channel) or other channels.

In another possible implementation manner, the control signaling may be higher layer signaling, other physical layer signaling except for the GC-PDCCH, or other signaling.

In step 504, the terminal determines the transmission format of the sub-resource in the incomplete resource according to the designated number and the designated location identifier.

The method comprises the steps that after a terminal receives a control signaling sent by a base station through an unauthorized frequency band, the specified number and the specified position identification included in the control signaling are obtained, incomplete resources in a resource set are determined according to the specified number and the specified position identification, and then the transmission format of the sub-resources in the incomplete resources is determined.

When the terminal communicates with the base station, one sub-resource is used as a unit, and each sub-resource is configured with one transmission format. The transmission format may include a plurality of formats, such as an uplink format, a downlink format, or an unknown format. For example, the uplink format is represented by U, the downlink format by D, and the unknown format by X. And when the transmission format of the sub-resource is a downlink format, the base station transmits data to the terminal through the sub-resource. When the transmission format of the sub-resource is an unknown format, the transmission format of the sub-resource is temporarily undetermined.

In the embodiment of the present disclosure, the step 504 may include the following steps 5041-5042:

In a possible implementation manner, the resource set includes an incomplete resource and a complete resource, and the terminal may determine the position of the incomplete resource in the resource set according to the specified position identifier.

When the incomplete resource is located at the first position in the resource set, the sub-resources with the previously specified number in the resource set are recombined into one incomplete resource, and each preset number of sub-resources in a plurality of sub-resources behind the incomplete resource are recombined into one complete resource, so that at least one complete resource is obtained.

When the incomplete resource is not located at the first position in the resource set, it is determined that the complete resource exists before the incomplete resource, and the number of the complete resource before the incomplete resource can be determined as the first number according to the specified position identification. Then, starting from the first sub-resource of the resource set, each preset number of sub-resources are recombined into a complete resource, and when the obtained number of the complete resource is the first number, the subsequent specified number of sub-resources are recombined into an incomplete resource. If the sub-resources exist behind the incomplete resources, recombining each preset number of sub-resources in the sub-resources behind the incomplete resources into one complete resource so as to obtain at least one complete resource behind the incomplete resources. By adopting the above manner, the plurality of sub-resources in the resource set can be ensured to be sequentially recombined into the plurality of resources, and unless the complete resources comprise the specified number of sub-resources, the other complete resources comprise the preset number of sub-resources.

The base station can obtain the indication information of each resource according to the transmission format of each sub-resource in each resource in the resource set, so that the indication information of each resource is formed into an indication information set. The subsequent terminal can determine the transmission format of the sub-resource according to the specified number of the resource set, the specified position identification and the indication information set.

The indication information set comprises a plurality of indication information respectively corresponding to a plurality of resources in the resource set, and the indication information is used for indicating the transmission formats of the sub-resources in the corresponding resources. The plurality of indication information in the indication information set are arranged according to the sequence of the plurality of resources in the resource set, and each indication information in the indication information set is matched with the position identification of each resource in the resource set.

In a possible implementation manner, the indication information may be an index identifier for querying a corresponding transmission format, or the indication information may be a transmission format of a sub-resource in a corresponding resource itself.

In another possible implementation manner, in order to facilitate flexible configuration of incomplete resources, the base station may recombine sub-resources on the basis of the original resources, so as to determine a specified number, a specified location identifier, and an indication information set according to the recombined resources, where the process may include the following steps 6011-6013:

And the first resource set comprises a plurality of initial resources configured by the base station, wherein a third resource is an incomplete resource.
