Description

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

Technical Field

The invention relates to the technical field of wireless communication, in particular to a method, equipment and a device for optimizing Physical Resource Block (PRB) utilization rate.

Background

In an LTE (Long Term Evolution) system, the types of transmission include new transmission, adaptive retransmission, and non-adaptive retransmission. Both the new transmission and the adaptive retransmission require a PDCCH (Physical Downlink Control Channel) to allocate a CCE (Control Channel Element) Resource for giving specific information indicating on which PRBs (Physical Resource blocks) can be transmitted. And the non-adaptive retransmission does not need any PDCCH resource, and 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, which can save the overhead of CCE resources, in one TTI (Transport Time Interval), if there are non-adaptive retransmissions in multiple PRB locations, the entire 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 cannot meet the transmission requirement of the current large data volume, and the small data volume cannot fully occupy PRB fragments, the PRB fragments cannot be fully occupied; therefore, the efficiency is low in terms of the efficiency of PRB utilization for the entire TTI.

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.

The term "and/or" in the embodiments of the present invention describes an association relationship of associated objects, and indicates that three relationships may exist, for example, a and/or B may indicate: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

The application scenario described in the embodiment of the present invention is for more clearly illustrating the technical solution of the embodiment of the present invention, and does not form a limitation on the technical solution provided in the embodiment of the present invention, and it can be known by a person skilled in the art that with the occurrence of a new application scenario, the technical solution provided in the embodiment of the present invention is also applicable to similar technical problems. In the description of the present invention, the term "plurality" means two or more unless otherwise specified.

In an LTE (Long Term Evolution) system, improving the utilization rate of PRB (Physical Resource Block), not only can improve the utilization efficiency of a frequency spectrum, but also has a significant effect on improving the throughput of the whole cell; for operators, under the condition of keeping the bandwidth unchanged, the increase of the throughput in unit time can directly bring the income of turnover.

Therefore, the method provided by the embodiment of the present invention increases the number of available continuous PRBs by reducing the fragments of PRBs, so as to improve the utilization efficiency of the spectrum.

As shown in fig. 1, an embodiment of the present invention provides a method for optimizing PRB utilization, which includes the following specific implementation steps:

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

step 101, allocating a Control Channel Element (CCE) resource for the SE to be converted according to the position of an idle PRB on a first segment of a time slot and/or a last segment of the time slot corresponding to the SE to be converted, wherein the CCE resource is used for indicating the position of the PRB used by the SE to be converted.

The method for optimizing the PRB utilization rate can be applied to partial scenes, and particularly has more non-adaptive transmission, so that the spectrum fragmentation is serious; and/or in the case of heavy data traffic. The method comprises the steps of converting a Scheduling Element (SE) fragment of a non-adaptive retransmission in the middle into an SE of the adaptive retransmission, and adjusting the converted SE to two sides of a frequency spectrum, so that enough continuous PRBs can be vacant in the middle of the frequency spectrum to bear large-data-volume services.

It should be noted that, the method for optimizing the utilization rate of the PRB is provided in the embodiment of the present invention, and is a method for optimizing the utilization rate of PRB resources on each timeslot by using a timeslot as a unit.

In the implementation, according to the service requirement, the SE to be converted can be determined from each scheduling unit SE of the non-adaptive retransmission; or randomly determining the SE to be converted from each scheduling unit SE of the non-adaptive retransmission; or determining the SE to be converted 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 optional implementation manner, the SE to be converted may also be determined from each scheduling element SE of the non-adaptive retransmission by any one or more of the following methods:

method 1,

For a more intuitive explanation, as shown in fig. 2, there are 100 PRB resources on the slot, and the PRB resources on the slot corresponding to the black parts on both sides indicate that the PRB resources are occupied by other resource channels and belong to unavailable PRB resources; the PRB resources on the time slot corresponding to the white part represent idle PRB resources, the PRB resources on the time slot corresponding to the gray part represent PRB resources of non-adaptive retransmission, wherein the idle PRB resources are identified by fragment A, fragment B, fragment C and fragment D, and the PRB resources of non-adaptive retransmission are identified by SE.

Among SEs of non-adaptive retransmission, SEs with idle PRBs on two adjacent sides are SE1, SE2 and SE 3; thus, SE1, SE2, SE3 were determined as SE to be transformed.

As shown in fig. 3, there are 100 PRB resources on the timeslot, and the PRB resources on the timeslot corresponding to the black parts on both sides indicate that the timeslot is already occupied by other resource channels and belongs to unavailable PRB resources; the PRB resources on the time slot corresponding to the white part represent idle PRB resources, the PRB resources on the time slot corresponding to the gray part represent PRB resources of non-adaptive retransmission, wherein the idle PRB resources are identified by fragment A, fragment B and fragment C, and the PRB resources of non-adaptive retransmission are identified by SE.

Among the SEs of the non-adaptive retransmission, the SE with idle PRBs on two adjacent sides is the SE1, and therefore the SE1 is determined as the SE to be converted.

Method 2,

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

in the embodiment of the invention, the allocation sequence of each SE can be determined according to the number of PRBs occupied by SEs with idle PRBs on two adjacent sides, namely, the SEs occupying more PRBs and the SEs occupying less PRBs preferentially allocate CCE resources; or, determining the allocation sequence of each SE according to the importance degree of transmission data corresponding to the SE with idle PRBs on two adjacent sides; or, the allocation sequence of each SE may be determined according to the PRBs occupied by the SEs having idle PRBs on both adjacent sides and the total number of idle PRBs on both adjacent sides, that is, the SE having the greater total number preferentially allocates CCE resources to the SE having the smaller total number.

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

determining the allocation sequence of each SE according to the quantity of idle PRBs on two adjacent sides in the SEs with the idle PRBs on two adjacent sides; wherein, the SE of the idle PRB with a large adjacent quantity preferentially allocates the CCE resource compared with the SE of the idle PRB with a small adjacent quantity.

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

As shown in fig. 4, there are 100 PRB resources on the timeslot, and the PRB resources on the timeslot corresponding to the black parts on both sides indicate that the timeslot is already occupied by other resource channels and belongs to unavailable PRB resources; the PRB resources on the time slot corresponding to the white part represent idle PRB resources, the PRB resources on the time slot corresponding to the gray part represent PRB resources of non-adaptive retransmission, wherein the idle PRB resources are identified by fragment A, fragment B, fragment C and fragment D, and the PRB resources of non-adaptive retransmission are identified by SE.

And determining the allocation sequence of each SE according to the SEs with idle PRBs on two adjacent sides and the number of idle PRBs on two adjacent sides as follows:

firstly, determining SE (sequence of sequence) of idle PRBs on two adjacent sides as SE1, SE2 and SE 3;

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, according to the mode that the SE of the idle PRB with a large adjacent quantity preferentially allocates the CCE resources compared with the SE of the idle PRB with a small adjacent quantity, determining the allocation sequence of each SE as follows: SE2, SE1, SE 3.

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

As an optional implementation manner, the SE to be converted may also be determined from each scheduling element SE of the non-adaptive retransmission by the following method:

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

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

the method comprises the following steps that 1, CCE resources are distributed to newly transmitted SEs currently;

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

The condition 2 is that the current retransmitted information does not accord with the TTI bundling characteristic of transmission time interval bundling;

it should be noted that TTI bundling is a method for transmitting a PUSCH (Physical Uplink Shared Channel) in a plurality of consecutive subframes, that is, a user equipment UE transmits a PUSCH in a bonded TTI;

the TTI bundling belongs to a characteristic in the VOLTE (Voice over Long-Term Evolution) standard.

And in condition 3, the currently retransmitted information does not accord with the retransmission of the clustered PUSCH Retx characteristic.

It should be noted that the clustered PUSCH ReTx characteristic is used to indicate that one user terminal UE may invoke multiple PRB resource segments in one slot.

As an optional implementation manner, in the embodiment of the present invention, CCE resources are allocated to the SE to be transformed, where the CCE resources include any one or any one 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 a first segment of a time slot corresponding to the SE to be converted;

that is to say, in the embodiment of the present invention, a control channel element CCE resource may be allocated to the SE to be converted, so as to indicate that the SE to be converted uses a position of an idle PRB on a first segment of a time slot corresponding to the SE to be converted.

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

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

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

that is to say, in the embodiment of the present invention, a control channel element CCE resource may be allocated to the SE to be converted, where the CCE resource is used to indicate that the SE to be converted uses the positions of idle PRBs on the first segment of the timeslot and the last segment of the timeslot, where the positions correspond to the SE to be converted.

In this way, it should be noted that, if there are multiple SEs to be converted, one of the SEs to be converted may be adjusted to the position of an idle PRB on the leading segment of a timeslot, and the other SE to be converted may be adjusted to the position of an idle PRB on the trailing segment of a timeslot; if the number of the SE to be converted is one, the SE to be converted may be adjusted to the position of the idle PRB on the leading segment of the timeslot, or the SE to be converted may be adjusted to the position of the idle PRB on the trailing segment of the timeslot.

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

In this way, since the number of the newly transmitted SE is limited, the CCE resource occupied by the newly transmitted SE is limited, and a suitable CCE resource can be reserved for the non-adaptive to adaptive SE (i.e., the SE to be converted), thereby performing allocation.

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

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

As an optional implementation manner, in the embodiment of the present invention, allocating CCE resources to the SE to be transformed further includes:

In summary, the method for optimizing the PRB utilization ratio provided in the embodiment of the present invention is characterized in that, in a 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 a frequency spectrum as much as possible. In addition, in the processing process, attention needs to be paid to the conversion from the non-adaptive retransmission SE to the adaptive retransmission SE, the number of the conversions, the influence on the PDCCH resource, and the influence on the newly transmitted data. The number of the corresponding convertible products can be selected according to the actual situation of the network, so that the situation that the number of the convertible products is large and the application of CCE resources is newly transmitted 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.
