Description

Method and device for joint scheduling of PUSCH (physical uplink shared channel) resources and PHICH (physical hybrid automatic repeat request indicator channel) resources
Technical Field
The invention relates to the technical field of communication, in particular to a method and a device for joint scheduling of PUSCH (physical uplink shared channel) resources and PHICH (physical hybrid automatic repeat request indicator channel) resources.
Background
The maximum system bandwidth that an LTE (Long Term Evolution ) system can support is 20MHz, and in order to better support a wideband system, the LTE system employs SC-FDMA (Single Carrier-Frequency Division Multiple Access), and divides a whole wideband Frequency selective channel into a plurality of flat sub-channels in a Frequency domain, and the sub-channels are orthogonal to each other. Under the condition of multi-user service coexistence, time-frequency resources can be flexibly allocated to carry out data transmission. The minimum Physical Resource unit that can be allocated is PRB (Physical Resource Block), and a Physical Resource with a continuous width of 180kHz in the frequency domain in one slot becomes one PRB. In order to support the single carrier characteristic of PUSCH (Physical Uplink Shared Channel) transmission, PUSCH resources are continuously allocated, that is, PRB resources that are continuously allocated to one user are required.
In order to improve the resource utilization rate and the system throughput and meet the QoS (Quality of Service) requirements of various services, the LTE system uses a shared channel mechanism to realize resource sharing of each user and each Service in the system by a dynamic resource allocation manner. A channel used for uplink data transmission of a UE (User Equipment) is referred to as a PUSCH.
The LTE system transmits HARQ (Hybrid Automatic Repeat Request) feedback (ACK/NACK) information for a PUSCH data packet using a PHICH (Physical Hybrid ARQ Indicator Channel). And the UE determines whether to retransmit the PUSCH data packet or not according to the feedback information. The downlink ACK/NACK feedback and the corresponding PUSCH transmission have a certain time sequence relation, so for the PUSCH transmission on the same subframe, the corresponding ACK/NACK feedback is also carried out on the same downlink subframe. The PHICH resource is mapped to a control region of the downlink subframe. Dividing system PHICH resources into a plurality of PHICH groups according to system configuration, wherein each PHICH group occupies different time-frequency resources; each PHICH group can bear ACK/NACK information of a plurality of UEs, ACK/NACK of different UEs in the same PHICH group is subjected to code division multiplexing, and the upper limit of the number of ACK/NACK bits capable of being subjected to code division multiplexing is determined. Thus, the PHICH resource of the UE is numbered by a pairIdentification of, wherein
Figure GDA00002974794000022
Is a sequence number of the PHICH group,is the number of the orthogonal sequence in a group, and the specific calculation formula of the two numbers is as follows:
n PHICH group = ( I PRB _ RA lowest _ index + n DMRS ) mod N PHICH group + I PHICH N PHICH group
Figure GDA00002974794000025
wherein n isDMRSIs a DMRS (Demodulation reference symbol) cyclic shift value indicated in a PDCCH (Physical Downlink Control Channel) corresponding to PUSCH transmission, and n is n if the DMRS cyclic shift value is a PUSCH corresponding to semi-persistent scheduling or PUSCH transmission scheduled by random access responseDMRSSet to 0;is the spreading factor size of the PHICH modulation;is the lowest PRB sequence number allocated to the first time slot of the corresponding PUSCH transmission;
Figure GDA00002974794000028
the number of PHICH groups;
Figure GDA00002974794000029
as can be seen from the above formula, the PHICH resource location of the UE is determined by the lowest PRB number in the resource occupied by PUSCH transmission and the user-level DMRS cyclic shift.
Currently, when performing uplink scheduling, all UEs in a default cell use the same n firstDMRSAfter the PUSCH resource allocation is finished, according to the PUSCH resource allocation result and nDMRSCalculating PHICH resource location by initial value, if PHICH resource collision is found by adjusting nDMRSTrying to change the PHICH resource position, if the PHICH resource can be allocated, successfully scheduling the current UE; otherwise, the current UE is not scheduled.
In the process of implementing the invention, the inventor finds that the prior art has at least the following defects:
the current scheduling method allocates the PUSCH resources first, and allocates the PHICH resources by adjusting the user-level DMRS cyclic shift after the PUSCH resources are allocated. By adopting the method, on one hand, certain complexity exists in adjusting user-level DMRS cyclic shift under the condition of PHICH resource conflict; on the other hand, the DMRS cyclic shift for each UE is jointly determined by the cell-level DMRS cyclic shift and the user-level DMRS cyclic shift. Under the same-frequency networking, for users using the same PUSCH resource for data transmission in adjacent cells, different DMRS cyclic shifts need to be allocated to ensure the orthogonality of the DMRSs thereof, so as to reduce the inter-cell same-frequency interference. The minimization of co-channel interference among cells can be ensured by configuring the cell-level DMRS cyclic shift. In order to follow the principle, when allocating the user-level DMRS cyclic shift to each UE, the allocation condition of the user-level DMRS cyclic shift of users using the same PUSCH resource for data transmission in different cells needs to be considered, that is, users using the same PUSCH resource for data transmission in adjacent cells need to allocate the same user-level DMRS cyclic shift, so that the above restriction factors greatly limit the degree of freedom of adjustment of the user-level DMRS when PHICH resource conflicts occur, thereby affecting the scheduling of the UE, increasing the transmission delay of uplink data, and being not beneficial to ensuring the service QoS.

Detailed Description
The embodiment of the invention provides a technical scheme for jointly scheduling PHICH resources and PUSCH resources. In the technical scheme, a UE priority queue participating in frequency domain scheduling is determined based on a known time domain scheduling method, for each UE scheduled in the frequency domain, user level DMRS cyclic shift of the UE is determined, the starting PRB sequence number which cannot be used as PUSCH transmission of the UE is determined by combining the current PHICH resource availability of a system, then PUSCH resource allocation is carried out on the current UE according to the limiting factor, and after the PUSCH resource allocation of the current UE is completed, the corresponding PHICH resource is determined. The method allocates the PUSCH resources to the UE and allocates the PHICH resources to the UE at the same time, ensures that the PHICH resources among the UEs do not conflict, and simultaneously ensures the transmission performance of the PUSCH and the PHICH.
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1, a flowchart of jointly scheduling PHICH resources and PUSCH resources according to an embodiment of the present invention is shown. The process is suitable for single-antenna transmission of the PUSCH, namely, the condition that virtual MU-MIMO (hereinafter referred to as intra-cell MU-MIMO) is not considered, namely, the condition that users in the same cell use the same PUSCH resource for data transmission is not considered. As shown, the process may include:
step 101, determining a user-level DMRS cyclic shift value of UE in a system. In a single-antenna transmission scenario, the same user-level DMRS cyclic shift is configured for all UEs, for example, all UEs are configured to be 0.
Step 102, performing time domain scheduling on the UE in the current system, and determining a UE priority queue participating in frequency domain scheduling.
Step 103, taking out the UE with the highest priority from the UE priority queue participating in frequency domain scheduling (the UE taken out from the head of the queue usually has the highest priority), and determining, according to the availability of the PHICH resource of the current system, the starting PRB resource location that cannot be used as PUSCH transmission of the current UE, in combination with the user-level DMRS cyclic shift of the current UE, that is, determining the PRB resource location whose PRB resource location cannot be used as the starting PRB resource in the continuous PRB resources that can be allocated to the current UE.
And step 104, distributing PUSCH resources for the current UE according to the current PUSCH availability of the system and the position of the initial PRB resource which cannot be used as the PUSCH transmission of the UE and is determined in step 103.
And 105, determining a corresponding PHICH resource according to the PUSCH resource allocation result of the current UE and the user-level DMRS cyclic shift determined in the step 101, and allocating the PHICH resource to the current UE.
Specifically, after the starting PRB position allocated to the UE and the user-level DMRS cyclic shift are determined, the PHICH resource may be allocated to the UE according to the PHICH resource calculation formula given by formula [1 ].
And 106, updating the PUCCH resources and PHICH resources available to the system, and deleting the current UE from the frequency domain scheduling UE priority queue.
Step 107, if the UE priority queue is not empty and the current system has available PUSCH resources and PHICH resources, then step 103 is carried out; otherwise, the scheduling is finished and the process is exited.
In step 103 in the flow shown in fig. 1, a process of determining, according to a situation that PHICH resources of a current system are available, a starting PRB resource location that cannot be used for PUSCH transmission of a current UE in combination with a user-level DMRS cyclic shift of the current UE may include, as shown in fig. 2:
step 201, determining the mapping relationship between the PRB resource and the PHICH resource according to the system resource configuration.
Specifically, the calculation formula [1] from PHICH resources]It can be seen that when the same user-level DMRS cyclic shift is allocated to all UEs in the system, the lowest PRB resource sequence number corresponding to PUSCH transmission

Mapped to the same PHICH group, PRB0, PRB3, PRB6 … … as shown in FIG. 3 are mapped to the same group (PHICH group 0)。
Step 202, according to the available situation of the PHICH resource of the current system, determining the starting PRB sequence number which can not be used as the PUSCH transmission of the current UE.
Specifically, according to the mapping relationship between the PRB resources and the PHICH resources determined in step 201, the PRB number corresponding to the PHICH resource already allocated to another UE may be determined as the PRB resource location that cannot be allocated to the current UE as the starting PRB. Still taking fig. 3 as an example, assuming that PHICH resources represented by white small squares in fig. 3 are currently available PHICH resources, and PHICH resources represented by slashed small squares are PHICH resources already allocated to other UEs, for the current UE, PRB0, PRB7, PRB15, PRB24, PRB31, PRB39, and PRB48, which cannot be allocated to the current UE as a starting PRB for PUSCH transmission.
In step 104 of the flow shown in fig. 1, a process of allocating PUSCH resources for a current UE according to a current PUSCH availability of a system and a starting PRB resource location that cannot be used for PUSCH transmission of the current UE may be as shown in fig. 4, and includes:
step 401, determining available continuous PRB resource segments according to the current available PUSCH resource situation.
Specifically, for the current available PRB resources of the system, combining is performed according to the principle of PRB resource continuity, so as to obtain available continuous PRB segments. For convenience of description, in this embodiment, the obtained number of available continuous PRB segments is denoted as K, and the number of PRBs included in each available continuous PRB segment is denoted as NPRB_usable_segk（0≤k＜K）。
Step 402, determining the number of PRBs that need to be allocated to the current UE according to the data volume to be transmitted by the current UE.
There are many methods for determining the number of PRBs required to be allocated to the current UE according to the amount of data to be transmitted by the UE, and the method can be roughly estimated, for example, the estimation is performed according to the average channel quality of the current UE in the whole system bandwidth, and at this time, for each available continuous PRB segment, the number of PRBs required to be allocated is the estimationThe value is obtained. The embodiment of the invention preferably adopts the method of respectively estimating the PRB number requirement of each available continuous PRB segment according to the average CQI on the PRB contained in each available continuous PRB segment, mainly considering the difference of the CQI on each PRB of the UE, obviously, the method is more accurate than the former method. Specifically, for each available continuous PRB segment, based on a CQI (Channel Quality Indicator) of the current UE on the PRBs, a corresponding MCS (Modulation and Coding Scheme) is determined according to an AMC (Adaptive Modulation Coding) algorithm, and a number N of PRBs that need to be allocated for data transmission using the MCS is calculated according to a data amount to be transmitted by the current UEPRB_need_segk（0≤k＜K）。
Step 403, performing PRB pre-allocation for the current UE in each available continuous PRB segment according to the number of PRBs allocated to the current UE as needed.
In this step, for each available continuous PRB segment, the optimal resources within the continuous PRB segment may be selected by performing a sliding window operation, i.e. PRB pre-allocation within each available continuous PRB segment.
Specifically, for an available continuous PRB segment K (0 ≦ K < K), first determining the sliding window length of the available continuous PRB segment:
Lwindow_segk＝min{NPRB_need_segk,NPRB_usable_segk}……[2]
assuming that the starting PRB resource set that cannot be allocated to the current UE, determined according to the availability of the PHICH resource of the current system, is Ω, the following methods may be used for different situations:
the first condition is as follows: if L iswindow_segk＝NPRB_usable_segkThen it indicates that the number of PRBs contained in the currently available continuous PRB segment is less than or equal to the number of PRBs required by the current UE. For Lwindow_segk＝NPRB_usable_segkThe available contiguous PRB segments, no sliding window needs to be performed. If the available continuous PRBIf the starting PRB of the segment does not belong to the set omega, all PRB resources in the available continuous PRB segment are pre-allocated resources corresponding to the available continuous PRB segment; otherwise, the remaining continuous PRB resources after removing the initial PRB in the available continuous PRB segment are used as the pre-segment resources of the available PRB continuous segment.
Case two: if L iswindow_segk＜NPRB_usable_segkThen it indicates that the number of PRBs contained in the currently available continuous PRB segment is greater than the number of PRBs required by the current UE. For the
Figure GDA00002974794000091
The available contiguous PRB segments, a sliding window needs to be performed. Assume that N is before the available contiguous PRB segmentPRB_usable_segk-Lwindow_segk+1 PRBs with N'PRB_segkA PRB belongs to the set Ω (i.e. it cannot be the starting PRB for allocation), the number of sliding windows performed in the available consecutive PRB segments is NPRB_usable_segk-Lwindow_segk+1-N′PRB_segk. Picking the best (e.g., highest average CQI) L of the available PRB segments based on a sliding window operationwindow_segkA number of contiguous PRB resources.
Further, in the above-mentioned first or second case, for each available continuous PRB segment, according to the result of PRB resource pre-allocation, if the number of PRBs selected from the result is smaller than the number of PRBs included in the available continuous PRB segment, because there is a certain difference in CQI on each PRB of the UE, at this time, it is necessary to recalculate a corresponding MCS according to the selected CQI on these PRBs according to an AMC algorithm, and further determine the data amount that can be carried by performing data transmission on these PRBs using the MCS.
In step 404, a final decision on resource allocation is made by comparing the pre-allocation results of PRB resources for each available continuous PRB segment.
The basic idea of resource allocation decision is to preferentially guarantee the QoS (Quality of Service) requirements of the UE, specifically, each resource allocation is the requirement for guaranteeing the data transmission of the UE, and on this basis, the efficiency of data transmission is improved as much as possible to improve the spectrum efficiency of the system. Based on the above principle, in the embodiments of the present invention, the priority of each pre-allocated PRB resource is determined according to the data carrying capacity and transmission efficiency of each pre-allocated PRB resource, and the pre-allocated PRB resource with the highest priority is selected as the PUSCH resource to be allocated to the current UE, specifically, the following resource allocation decision method is preferably adopted:
firstly, according to the comparison result between the data volume to be transmitted by the current UE and the data volume which can be transmitted by the pre-allocated continuous PRB in each continuous PRB segment, dividing the pre-allocation result of all PRBs into two sets S1 and S2: dividing PRB pre-allocation results with data transmission capacity not less than data transmission requirements into a set S1; the PRB pre-allocation results with data transmission capacity less than the data transmission requirement are divided into sets S2. Obviously, the result of PRB pre-allocation that meets the data transmission requirement has higher priority, i.e. the priority of the two sets is: s1> S2;
then, for the result of pre-allocation of PRBs in the set S1, since the data carrying capacity of the result satisfies the data transmission requirement, in order to ensure the transmission efficiency, the priority order of the pre-allocated PRBs may be determined by the MCS corresponding to each pre-allocated PRB in combination with the priority of the set S1. The higher the MCS, the higher the transmission efficiency, and generally the lower the number of PRBs, the higher its priority.
For each PRB pre-allocation result in the set S2, because the data carrying capacity of the PRB does not meet the data transmission requirement, in order to ensure the real-time performance of data transmission as much as possible, the priority of the set S2 may be combined, and the data carrying capacity of the pre-allocated PRB is used as a determination criterion of the priority, where the larger the data carrying capacity is, the higher the corresponding priority is.
Finally, the highest priority is selected from the PRB resource pre-allocation results of the available consecutive PRB segments in the set S1 and the set S2 as the final result of the PUSCH resource allocation.
The implementation manner of making the final decision of resource allocation is only an optimal manner by comparing the pre-allocation results of the PRB resources of the available continuous PRB segments, and if the resource allocation policies are different, if the transmission efficiency requirement is higher than the QoS requirement, the setting of the priority level is changed accordingly. In addition, according to the data transmission capability, the pre-allocated PRBs are firstly divided into different sets, only for the convenience of technical implementation, and a person skilled in the art should be able to make resource decisions in a similar manner based on the above basic ideas, for example, instead of dividing different sets, a rule for setting priorities according to the data transmission capability and the transmission efficiency is predefined, and a weight of the data transmission capability is set to be higher than a weight of the transmission efficiency.
In the method for jointly scheduling PHICH resources and PUSCH resources provided in the embodiments of the present invention, for each UE scheduled in the frequency domain, first, the user-level DMRS cyclic shift is determined, and the starting PRB number that cannot be used as PUSCH transmission for the UE is determined in accordance with the current PHICH resource availability of the system, then, PUSCH resources are allocated to the current UE according to the restriction factor, and after the PUSCH resources are allocated to the current UE, the corresponding PHICH resources are determined. The method allocates the PUSCH resources to the UE and allocates the PHICH resources to the UE at the same time, ensures that the PHICH resources among the UEs do not conflict, and simultaneously ensures the transmission performance of the PUSCH and the PHICH.
