Description

Method, equipment and device for optimizing utilization rate of physical resource block PRB

Technical Field

The present invention relates to the field of wireless communications technologies, and in particular, to a method, an apparatus, and a device for optimizing a utilization rate of a physical resource block PRB.

Background

In LTE (Long Term Evolution ) systems, the types of transmissions include new, adaptive and non-adaptive retransmissions. Both the new transmission and the adaptive retransmission require PDCCH (Physical Downlink Control Channel ) allocation CCE (Control Channel Element, control channel element) resources for giving specific information indicating on which PRBs (Physical Resource Block, physical resource blocks) can be transmitted. And the non-adaptive retransmission does not need any PDCCH resource, but only directly retransmits at the position of the last subframe transmission.

For PDCCH, although the current transmission scheme does not need any CCE resource for non-adaptive retransmission, and can save the cost of CCE resource, in one TTI (Transport Time Interval, transmission time interval), if there are non-adaptive retransmissions at multiple PRB positions, the whole spectrum may be divided into multiple PRB available fragments; if a large data volume service arrives and a small data volume service is less, the number of continuous PRBs can not meet the transmission requirement of the current large data volume, and the small data volume can not fully occupy the PRB fragments, so that the PRB fragments can not be fully occupied; therefore, the efficiency is relatively low in terms of PRB utilization efficiency of the entire TTI.

Detailed Description

All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

In the embodiment of the invention, the term "and/or" describes the association relation of the association objects, which means that three relations can exist, for example, a and/or B can be expressed as follows: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.

The application scenario described in the embodiment of the present invention is for more clearly describing the technical solution of the embodiment of the present invention, and does not constitute a limitation on the technical solution provided by the embodiment of the present invention, and as a person of ordinary skill in the art can know that the technical solution provided by the embodiment of the present invention is applicable to similar technical problems as the new application scenario appears. In the description of the present invention, unless otherwise indicated, the meaning of "a plurality" is two or more.

In an LTE (Long Term Evolution ) system, improving the utilization rate of PRBs (Physical Resource Block, physical resource blocks) not only improves the utilization efficiency of spectrum, but also has a remarkable effect on improving the throughput of the whole cell; for operators, under the condition of unchanged bandwidth, throughput in unit time is improved, and sales benefits can be directly brought.

Therefore, the method provided by the embodiment of the invention increases the utilization efficiency of the frequency spectrum by reducing the fragments of the PRB and increasing the number of available continuous PRBs, and the specific implementation method is as follows.

As shown in fig. 1, the embodiment of the invention provides a method for optimizing the utilization rate of PRBs, which comprises the following specific implementation steps:

step 100, determining SE to be converted from each scheduling unit SE of non-adaptive retransmission;

step 101, according to the positions of idle PRBs on the first slot segment and/or the last slot segment corresponding to the SE to be converted, control channel element CCE resources are allocated to the SE to be converted, where the CCE resources are used to indicate the positions of PRBs used by the SE to be converted.

The method for optimizing the PRB utilization rate provided by the embodiment of the invention can be applied to partial scenes, especially in a situation that more non-adaptive transmission is carried out, so that the frequency spectrum fragmentation is serious; and/or in the case of large data traffic. The intermediate non-adaptive retransmission scheduling units (Scheduled Element, SE) are fragmented into adaptive retransmission SE, and the transformed SE is adjusted to two sides of the frequency spectrum, so that the frequency spectrum can be free from enough continuous PRBs to bear large data traffic.

It should be noted that, the method for optimizing the PRB utilization provided by the embodiment of the present invention is a method for optimizing the utilization of PRB resources on each time slot by taking the time slot as a unit.

In implementation, according to service requirements, determining SE to be converted from each scheduling unit SE of non-adaptive retransmission; the SE to be converted can also be randomly determined from each scheduling unit SE of the non-adaptive retransmission; the SE to be converted can also be determined from each scheduling unit SE of the non-adaptive retransmission according to the preset priority of each SE of the non-adaptive retransmission;

as an alternative embodiment, the SE to be converted may also be determined from the scheduling units SE of the non-adaptive retransmission by any one or more of the following methods:

method 1,

For more visual explanation, as shown in fig. 2, there are 100 PRB resources in the time slot, and the PRB resources in the time slot corresponding to the black parts on both sides indicate that they are occupied by other resource channels and belong to unavailable PRB resources; the PRB resources on the time slots corresponding to the white portions represent free PRB resources, and the PRB resources on the time slots corresponding to the gray portions represent non-adaptively retransmitted PRB resources, where the free PRB resources are identified by FragmentA, fragmentB, fragmentC, fragmentD and the non-adaptively retransmitted PRB resources are identified by SE.

Among the SE of the non-adaptive retransmission, the SE with idle PRBs on both sides is SE1, SE2, SE3; thus, SE1, SE2, SE3 are determined as SE to be converted.

As shown in fig. 3, there are 100 PRB resources in the timeslot, and the PRB resources in the timeslot corresponding to the black parts on both sides indicate that they are occupied by other resource channels and belong to unavailable PRB resources; the PRB resources on the time slots corresponding to the white portions represent free PRB resources, and the PRB resources on the time slots corresponding to the gray portions represent non-adaptively retransmitted PRB resources, where the free PRB resources are identified by FragmentA, fragmentB, fragmentC and the non-adaptively retransmitted PRB resources are identified by SE.

Among the SE of the non-adaptive retransmission, the SE with idle PRBs on both sides is SE1, so SE1 is determined as the SE to be converted.

Method 2,

1) Determining the allocation sequence of each SE from the SE with idle PRBs on two adjacent sides in the non-adaptive retransmission;

in the embodiment of the invention, the allocation sequence of each SE can be determined according to the quantity of the PRBs occupied by the SE with the free PRBs on two adjacent sides, namely, the SE with more PRBs is occupied, and CCE resources are preferentially allocated to the SE with less PRBs; or determining the allocation sequence of each SE according to the importance degree of the transmission data corresponding to the SE with the idle PRB on two adjacent sides; alternatively, the allocation order of each SE, that is, the total number of SEs, may be determined according to the PRBs occupied by the SE having the free PRBs on both sides adjacent to each other and the total number of free PRBs on both sides adjacent to each other, and CCE resources may be preferentially allocated to the SE having the greater total number than the SE having the lesser total number.

As an alternative embodiment, the allocation order of each SE may also be determined by:

determining the allocation sequence of each SE according to the quantity of the idle PRBs on the two adjacent sides in the SE with the idle PRBs on the two adjacent sides; wherein, the SE of the idle PRB with a large number is adjacent to the SE of the idle PRB with a small number, and the SE of the idle PRB with a small number is adjacent to the SE of the idle PRB with a small number is preferentially allocated with CCE resources.

2) And selecting a preset number of SE according to the distribution sequence of each SE, and determining the SE as the SE to be converted.

As shown in fig. 4, there are 100 PRB resources in the timeslot, and the PRB resources in the timeslot corresponding to the black parts on both sides indicate that they are occupied by other resource channels and belong to unavailable PRB resources; the PRB resources on the time slots corresponding to the white portions represent free PRB resources, and the PRB resources on the time slots corresponding to the gray portions represent non-adaptively retransmitted PRB resources, where the free PRB resources are identified by FragmentA, fragmentB, fragmentC, fragmentD and the non-adaptively retransmitted PRB resources are identified by SE.

According to the SE with idle PRBs on both adjacent sides, determining the allocation sequence of each SE as follows:

firstly, determining SE with idle PRBs on two adjacent sides as SE1, SE2 and SE3;

secondly, the number of SE1 adjacent idle PRBs is 25, the number of SE2 adjacent idle PRBs is 30, and the number of SE3 adjacent idle PRBs is 16;

thirdly, determining the allocation sequence of each SE as follows according to the mode that the SE of the idle PRBs with a plurality of adjacent PRBs preferentially allocates CCE resources than the SE of the idle PRBs with a smaller number than the adjacent PRBs: SE2, SE1, SE3.

And finally, selecting 3 SE according to the distribution sequence of each SE, and determining the SE as the SE to be converted, namely selecting SE2, SE1 and SE3 as the SE to be converted, wherein the sequence to be converted is SE2, SE1 and SE3.

As an alternative embodiment, the SE to be converted may also be determined from the scheduling units SE of the non-adaptive retransmission by:

and selecting a preset number of SE from the SE with idle PRBs on two adjacent sides from the SE with non-adaptive retransmission, and determining the SE as the SE to be converted.

In addition, before determining the SE to be converted from each scheduling unit SE of the non-adaptive retransmission, the embodiment of the present invention further includes:

determining that any one or more of the following conditions are satisfied:

condition 1, currently needing to allocate CCE resources for newly transmitted SE;

it should be noted that the new transmission is one transmission type in the LTE system, and is used as three transmission types in the LTE system together with the adaptive retransmission and the non-adaptive retransmission, where the new transmission represents a new data transmission.

The condition 2, the information of the current retransmission does not accord with the transmission time interval bundling TTI bundling characteristic;

it should be noted that TTI bundling is a method for transmitting a PUSCH (Physical Uplink Shared Channel ) by a plurality of subframes in succession, that is, the UE transmits a PUSCH on a bundled TTI;

the TTI bundling belongs to one of the characteristics of the VOLTE (Voice over Long-Term Evolution) standard.

Condition 3, the information of the current retransmission does not conform to the aggregated physical uplink shared channel retransmission clustered PUSCH ReTx characteristics.

Note that clustered PUSCH ReTx characteristics are used to indicate that one user terminal UE may invoke a plurality of PRB resource segments on one slot.

As an optional implementation manner, in the embodiment of the present invention, CCE resources are allocated to the SE to be converted, including any one or any multiple of the following manners:

mode 1, allocating Control Channel Element (CCE) resources for the SE to be converted according to the position of an idle PRB on the first section of a time slot corresponding to the SE to be converted;

that is, the embodiment of the present invention may allocate a control channel element CCE resource to the SE to be converted, where the control channel element CCE resource is used to indicate a location where the SE to be converted uses an idle PRB on a first slot segment corresponding to the SE to be converted.

Mode 2, distributing Control Channel Element (CCE) resources for the SE to be converted according to the position of the idle PRB on the tail section of the time slot corresponding to the SE to be converted;

that is, the embodiment of the present invention may allocate a control channel element CCE resource to the SE to be converted, where the control channel element CCE resource is used to indicate a location where the SE to be converted uses an idle PRB on a slot end segment corresponding to the SE to be converted.

Mode 3, distributing Control Channel Element (CCE) resources for the SE to be converted according to the positions of idle PRBs on the first time slot segment and the last time slot segment corresponding to the SE to be converted;

that is, in the embodiment of the present invention, a control channel element CCE resource may be allocated to the SE to be converted, where the control channel element CCE resource is used to instruct the SE to be converted to use positions of idle PRBs on a first slot segment and a last slot segment corresponding to the SE to be converted.

In this manner, it should be noted that, if the to-be-converted SE is multiple, one of the to-be-converted SE may be adjusted to a position of an idle PRB on the first slot segment, and the other to-be-converted SE may be adjusted to a position of an idle PRB on the last slot segment; if the SE to be converted is one, the SE to be converted may be adjusted to the position of the idle PRB on the first slot segment, or the SE to be converted may be adjusted to the position of the idle PRB on the last slot segment.

Mode 4, limiting the number of newly transmitted SE according to preset transmission requirements; and distributing CCE resources except for the CCE resources corresponding to the newly transmitted SE for the SE to be converted.

In this way, the number of newly transmitted SE is limited, so that CCE resources occupied by the newly transmitted SE are limited, and appropriate CCE resources can be reserved for non-adaptive to adaptive SE (i.e. SE to be converted), so as to perform allocation.

And 5, if the current time slot comprises the newly transmitted SE and the SE to be converted, preferentially distributing CCE resources to the SE to be converted.

In this way, in order to avoid the influence on the newly transmitted SE when the CCE resource is allocated, a set number of SEs to be converted may be selected according to the actual situation, the CCE resource is preferentially allocated to the set number of SEs to be converted, and then the CCE resource is allocated to the newly transmitted SE.

As an optional implementation manner, in this embodiment of the present invention, CCE resources are allocated to the SE to be converted, and the method further includes:

In summary, the key point of the method for optimizing the PRB utilization provided by the embodiment of the present invention is that, in the processing manner of the non-adaptive retransmission SE, the position of the non-adaptive retransmission SE on the PUSCH is adjusted by converting the non-adaptive retransmission SE into the adaptive retransmission SE, and the non-adaptive retransmission SE is adjusted to both sides of the spectrum as much as possible. In addition, during the processing, attention needs to be paid to the conversion of non-adaptive retransmission SE into adaptive retransmission SE, the number of conversion and the influence on PDCCH resources, and further attention needs to be paid to the influence on new transmission data. The corresponding convertible number can be selected according to the actual condition of the network, so that the situation that the application of the CCE resource is newly transmitted is influenced due to the fact that the converted number is relatively large is avoided. Compared with the prior art, the method provided by the embodiment of the invention can effectively improve the cell throughput for most communication networks.
