Description

Method for indicating PRB bundling size and user terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method for indicating a physical resource block bundling size (PRB bundling size) and a user terminal.

Background

The PRB bundling size is used to instruct the user terminal to bundle a certain number of Physical Resource Blocks (PRBs) together into a Physical Resource Block bundle (PRB bundle). The current base station sends Downlink Control Information (DCI) to the user terminal, where the DCI carries PRB bundling size, and the user terminal obtains the PRB bundling size from the DCI after receiving the DCI. In practical applications, the DCI needs to carry other information besides the recommended PRB bundling size, for example: a Transmitted Precoding Matrix Indicator (TPMI), an uplink Scheduling Request Indicator (SRI), a Transmitted Rank Indicator (TRI), and the like. The DCI needs to carry PRB bundling size, which results in large overhead of the DCI.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a structural diagram of an indication system of PRB bundling size according to an embodiment of the present invention, and as shown in fig. 1, the indication system includes a user terminal 11 and a base station 12, where the user terminal 11 may be a ue (user equipment), for example: the terminal may be a terminal side Device such as a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), or a Wearable Device (Wearable Device), and it should be noted that the specific type of the terminal 11 is not limited in the embodiments of the present invention. The base station 12 may be a 5G base station (e.g., a gNB or a 5G NR NB), and it should be noted that the specific type of the base station 12 is not limited in the embodiment of the present invention.

It should be noted that the specific functions of the user terminal 11 and the base station 12 are described in detail through a plurality of embodiments below.

Referring to fig. 2, fig. 2 is a schematic diagram of a method for indicating PRB bundling size according to an embodiment of the present invention, where the method is applied to a user terminal, and as shown in fig. 2, the method includes the following steps:

step 201, receiving DCI sent by a base station, where the DCI includes TPMIs, and the number of the TPMIs included in the DCI implicitly indicates PRB bundling size.

The DCI may be DCI of a corresponding length selected by the base station according to the number of configured TPMIs. In addition, the DCI may include other information in addition to the TPMI, for example: SRI or TRI, etc.

The implicit indication of the number of the TPMI included in the DCI for the PRB bundling size may be understood as that the user terminal may be notified of the corresponding PRB bundling size according to the number of the TPMI included in the DCI, that is, the user terminal may know the specific PRB bundling size according to the number of the TPMI included in the DCI.

Step 202, determining the PRB bundling size according to the number of TPMIs included in the obtained DCI and the scheduling bandwidth of the user terminal.

The step may be to determine the PRB bundling size according to a correspondence relationship between a pre-obtained number of TPMI, a pre-obtained scheduling bandwidth, and a pre-obtained PRB bundling size, where the correspondence relationship includes multiple sets of numbers of TPMI, pre-obtained scheduling bandwidths, and pre-obtained PRB bundling sizes corresponding to each set, so that the PRB bundling size may be determined quickly and accurately according to the correspondence relationship, so as to avoid performance degradation influence caused by undefined PRB bundling size.

Of course, step 202 may also be dividing the scheduling bandwidth of the user terminal by the number of TPMIs included in the DCI to obtain the PRB bundling size, for example: dividing the scheduling bandwidth by the number of the TPMI (scheduled BW/TPMI) included in the DCI to obtain an integer, and taking the integer as the PRB bundling size. For the case that the number of TPMI cannot be divided, the obtained integer may be regarded as one PRB bundling size, and for the remainder part, the number of bars may be regarded as another PRB bundling size, that is, the PRB bundling size is equal to the remainder. For example: and if the scheduling bandwidth is 20 PRBs, and the number of the TPMI is 3, obtaining a PRB bundling size of 6, and if there is a remainder 2, obtaining another PRB bundling size of 2.

Of course, in the embodiment of the present invention, an upward rounding or a downward rounding may be adopted, and the obtained integer is used as the PRB bundling size, so that the PRB bundling size may be determined, and the influence of performance degradation caused by undefined PRB bundling size may be avoided.

The method can be applied to a 5G system, but is not limited to the following, for example: but also to future 6G systems, etc.

In the embodiment of the invention, downlink control information DCI sent by a base station is received, wherein the DCI comprises TPMI, and the number of the TPMI contained in the DCI implicitly indicates PRB bundling size; and dividing the scheduling bandwidth of the user terminal by the number of TPMI (transport layer indicator) included in the DCI to obtain the PRB bundling size. Because the PRB bundling size is implicitly indicated, the DCI overhead can be reduced, and the PRB bundling size can be determined, so that the influence of performance deterioration caused by undefined PRB bundling size can be avoided, and the performance of the user terminal can be improved.

Referring to fig. 3, fig. 3 is a schematic diagram of another method for indicating PRB bundling size according to an embodiment of the present invention, where the method is applied to a user terminal, and as shown in fig. 3, the method includes the following steps:

step 301, receiving DCI sent by a base station, where the DCI includes TPMIs, and the number of the TPMIs included in the DCI implicitly indicates PRB bundling size.

Step 302, determining the PRB bundling size according to the number of TPMIs included in the obtained DCI and the scheduling bandwidth of the user terminal.

And step 303, binding the scheduling bandwidth into at least one PRB bundle according to the PRB bundling size, where the number of PRBs included in any PRB bundle is the PRB bundling size, or the number of PRBs included in one PRB bundle in the at least one PRB bundle is smaller than the PRB bundling size, and the number of PRBs included in any remaining PRB bundle is the PRB bundling size.

The scheduling bandwidth may be configured to the user terminal by the network side, for example: 10 or 20 PRBs are configured. The number of PRBs included in any PRB bundle is the PRB bundling size, and it is understood that the number of PRBs included in each PRB bundle is the same, for example: the number of PRBs of the scheduling bandwidth may be divided into the whole number of PRB bundling sizes, for example, if the number of PRBs of the scheduling bandwidth is 20, and the number of PRBs of each PRB bundle is 4, then the number of PRBs included in each PRB bundle is 4.

The number of PRBs included in one PRB bundle of the at least one PRB bundle is smaller than the PRB bundling size, and the number of PRBs included in any remaining PRB bundle is the PRB bundling size, where it can be understood that when at least one PRB bundle is multiple PRB bundles, a PRB of a scheduling bandwidth cannot divide the PRB bundling size, for example: the number of PRBs in the scheduling bandwidth is 10, and the PRB bundling size is 3, then the number of PRBs included in 3 PRB bundles is 3, and the number of PRBs included in another PRB bundle is 1. That is, for the condition that the PRB bundling size cannot be evenly divided by the PRB of the scheduling bandwidth, the user terminal automatically reduces the PRB bundling size of the last part of the remainder, so that the PRB bundling size is equal to the remainder.

As an alternative to the above-described embodiment,

before the bundling the scheduling bandwidth into at least one PRB bundle according to the PRB bundling size, the method further includes:

receiving the mesh information configured by the base station;

the binding the scheduling bandwidth into at least one PRB bundle according to the PRB bundling size includes:

and according to the grid information, dividing the scheduling bandwidth into at least one PRB region, and binding each PRB region into at least one PRB bundle according to the PRB bundling size.

Here, the above-mentioned mesh information may be understood as information for dividing PRB resources into a plurality of regions, and the mesh information may include a region interval. For example: as shown in fig. 4, the PRB indices (indices) 0 to X are divided into a plurality of PRB regions, and the size of each PRB region is the above-described region interval. For example: a user terminal schedules a PRB with a bandwidth as shown in 401 in fig. 4, so that the PRB with the scheduling bandwidth is divided into 6 PRB regions in this embodiment, where the size of the head and tail PRB regions only occupies a partial region interval; another example is: the PRB of the scheduling bandwidth of another user terminal is shown as 402 in fig. 4, and then the PRB of the scheduling bandwidth is divided into 5 PRB regions in the present embodiment, and each PRB region size is equal to the region interval.

In addition, after the PRB region is divided into a plurality of PRB regions, the PRBbundle is independently made in each divided PRB region. Similarly, for the situation that the divided region cannot divide the PRB bundling size in an integer, the user terminal automatically reduces the PRB bundling size of the last part of the remainder, so that the PRB bundling size is equal to the remainder. For example, the divided PRB region is 5 PRBs, the network indicates that the PRB bundling size is equal to 2, and the size of the PRB bundle configured by the user terminal by the 5 PRBs of the divided PRB region is 2 PRBs, 1 PRB, where 1 PRB is equal to the remainder (5/2).

In this embodiment, the user terminals can divide the scheduling bandwidth into at least one PRB region according to the grid information, so that most of prbbundles included in the scheduling bandwidths of different user terminals are aligned, thereby reducing interference among multiple user terminals and improving the overall communication performance of the network.

As another optional implementation manner, before the bundling of the scheduling bandwidth into at least one PRB bundle according to the PRB bundling size, the method includes:

receiving PRB grouping information configured by the base station;

and according to the PRB grouping information, dividing the scheduling bandwidth into at least one PRB group, and binding the at least one PRB group into at least one PRB bundle according to the PRB bundling size.

The PRB grouping information is used to indicate that the scheduling bandwidth is divided into at least one PRB grouping, and the PRB grouping information may include the number of PRBs included in each PRB grouping, or include a division rule of the PRB grouping, and the like, which is not limited in this embodiment of the present invention. In addition, the partitioning of PRB packets may support non-uniform allocation, such as: the number of PRBs in the scheduling bandwidth is 10, and the scheduling bandwidth may be divided into 3 PRB groups, 4 PRB groups, and 3 PRB groups, or may be divided into two 5 PRB groups.

In addition, it should be noted that, because the PRB bundling size is implicitly indicated, the size of some PRB packets may be larger than the PRB bundling size in the PRB packet information allocated by the base station, or the size of some PRB packets may be smaller than the PRB bundling size. In order to ensure the integrity of the PRB packets and PRB bundles and improve the PRB bundle transmission performance for these situations, in the present embodiment, the following rules are used for partitioning:

aiming at the PRB groups of which the number of PRBs is greater than or equal to the PRB bundling size, the PRB groups comprise at least one PRB bundle; and/or

Aiming at the PRB group with the number of PRBs smaller than the PRB bundling size, the PRB group belongs to one PRB bundle.

The PRB packet includes at least one PRB packet, which may be understood as that the PRB of the PRB packet included in the PRB packet only belongs to the PRB packet, and there is no case where the PRB of one PRB packet is included in multiple PRB packets. For example: the PRB packet 1 comprises a PRB bundle1 and a PRB bundle2, and all PRBs comprised by the PRB bundle1 and the PRB bundle2 belong to the PRB packet 1.

By the rule, all PRBs in the PRB bundle can be ensured to belong to the same PRB group, or all PRB bundles in one PRB group are the same. The finally formed PRB bundle contains a complete PRB packet, or the PRB packet contains a complete PRB bundle.

In this embodiment, because the PRB grouping is performed first and then the PRB bundle is performed, the accuracy of the PRB bundle can be improved, so as to improve the transmission performance of the PRB bundle.

Step 304, mapping the precoding indicated by the TPMI included in the DCI to each PRB bundle, wherein the PRBs belonging to the same PRB bundle map the precoding indicated by the same TPMI.

The mapping of the precoding indicated by the TPMI included in the DCI to each PRB bundle may be understood as that each PRB bundle is mapped with the precoding, but the PRBs in the same PRB bundle are mapped with the precoding indicated by the same TPMI, that is, one PRB bundle is mapped with only one precoding. Some different PRB bundles are allowed to map the same precoding. For example: precoding 1 is mapped to PRB bundle1 of PRB region 1 (or PRB packet 1), precoding 2 is mapped to PRB bundle2 of PRB region 1 (or PRB packet 1), precoding 1 is mapped to PRB bundle1 of PRB region 2 (or PRB packet 2), and precoding 2 is mapped to PRB bundle2 of PRB region 2 (or PRB packet 2).

The PRB belonging to the same PRB bundle is mapped to the precoding indicated by the same TPMI, so that the same precoding can be used by the PRB in the same PRB bundle, and the base station can perform channel estimation by taking the PRB bundle as a channel estimation unit so as to improve the channel estimation performance.

As an optional implementation, the mapping the precoding indicated by the TPMI included in the DCI to each PRB bundle includes:

mapping a precoding indicated by one TPMI included in the DCI to each PRB bundle;

or

Bundling the scheduling bandwidth into a plurality of PRB bundles, and mapping the precoding indicated by the TPMI included in the DCI onto each PRB bundle, including:

mapping precodes indicated by a plurality of TPMI included in the DCI to the plurality of PRB bundles respectively.

In this embodiment, the same precoding mapped on each PRB bundle can be implemented. Or, the step 303 may be implemented to obtain a plurality of PRB bundles, and map the precodes indicated by the plurality of TPMIs to the plurality of PRB bundles. For example: if the scheduling bandwidth comprises 5 PRB bundles, and the DCI comprises 5 TPMI, different PRB bundles can be mapped to different precodes; or if the scheduling bandwidth includes 5 PRB bundles, and the DCI includes 3 TPMI, the 3 precodes may be mapped to the 5 PRB bundles, and the specific mapping manner is not limited. In addition, in the embodiment of the PRB region or PRB packet, if one PRB region or PRB packet includes multiple PRB bundles, the precodes indicated by multiple TPMI may be mapped to the multiple PRB bundles, and the precodes mapped to each PRB region or PRB packet may have the same part or different parts, which is not limited in this embodiment of the present invention.

In this embodiment, the implicit indication of the PRB bundling size may be implemented through the above steps, so as to reduce the overhead of DCI, improve the influence of performance degradation caused by undefined PRB bundling size, and reduce interference between multiple user terminals.
