Description

Processing method and device for allocating PUCCH resources for CSI
Technical Field
The invention relates to the technical field of communication, in particular to a processing method and a processing device for allocating PUCCH resources for CSI.
Background
A Physical Uplink Control Channel (PUCCH) CSI (Channel state information) may feed back the quality of a downlink Channel to the base station, so that the base station may select the downlink Channel with better Channel quality to perform downlink data scheduling, so as to ensure user experience. Therefore, how to allocate PUCCH resources for CSI is also important.
At present, PUCCH resources are generally allocated to CSI in units of cells. Specifically, when the cell establishes resource initialization, PUCCH resources for transmitting CSI may be reserved in units of cells. The PUCCH resources used for transmitting the CSI can be stored through linked lists, each time domain resource corresponds to one linked list, nodes in each linked list are all available PUCCH resources determined according to frequency domains and code domains, and the condition of idle PUCCH resources in the linked lists can be further stored in each linked list. When a PUCCH resource is allocated to a UE (User equipment), a time domain position of the PUCCH resource used for transmitting CSI may be determined first, and then, corresponding PUCCH resources may be allocated in the reserved PUCCH resource region in a linked list corresponding to the time domain position according to a sequence. Referring to fig. 1 (where PUSCH is a channel for transmitting traffic data), PUCCH resources for transmitting CSI generally adopt PUCCH Format3 Format, and the reserved PUCCH resources are located on RBs (Resource Block) near the lower edge of the frequency band, that is, the PUCCH resources for transmitting CSI are divided first, and then the PUCCH resources for transmitting SR (Scheduling Request, Scheduling Request information) and ACK (Acknowledgement)/NACK (Negative Acknowledgement) are divided.
In the prior art, when there are fewer cell access users, there are more PUCCH resources for CSI transmission that are idle, because the PUCCH resources for CSI transmission are discontinuous with the PUSCH. Therefore, idle PUCCH resources for CSI transmission cannot be used for data transmission, so that PUCCH resources are wasted, a user peak speed is affected, and user experience is affected.

Detailed Description
The following further describes embodiments of the present invention with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Fig. 2 shows a flowchart of a method for allocating PUCCH resources for CSI provided in this embodiment, where the method includes:
s201, acquiring a transmission period of CSI (channel state indication) and a transmission period of SRS (sounding reference signal), and determining a target time slot of the CSI based on the transmission period of the CSI and the transmission period of the SRS.
Wherein the target slot includes one or more symbol groups.
The target time slot refers to a time slot position in time domain information corresponding to a PUCCH resource used for transmitting CSI.
In implementation, when a UE accesses, a target slot is determined based on a transmission period of a CSI (channel state information) and a transmission period of an SRS (sounding Reference Signal), a target PRB (physical resource block) and a target symbol group are determined based on the target slot, and a PUCCH resource is allocated to the CSI based on the target slot, the target PRB, and the target symbol group. Specifically, the CSI transmission period and the SRS transmission period may be obtained to determine a target slot corresponding to a PUCCH resource to be allocated for CSI (i.e., a PUCCH resource for transmitting CSI) based on the CSI transmission period and the SRS transmission period. The specific process of determining the target timeslot may be as follows:
first, PUCCH resources may be allocated for SRS first: the SRS is uniformly distributed in the time domain. The PUCCH resources can be stored in a time-division domain (namely time slots), the number of corresponding idle PUCCH resources is stored at the head of a time slot resource chain, and the time slot resource chain with the largest number of idle PUCCH resources is searched according to the time slot sequence for allocation. Then, PUCCH resources may be allocated for CSI: allocating PUCCH resources for CSI requires that the slot position for allocating PUCCH resources for SRS be followed and approached by the slot position for allocating PUCCH resources for SRS. The specific allocation process can be divided into two cases, see fig. 3, where NpRepresenting CSITransmission period, TsrsIndicates the SRS transmission period. In the first case (see a in fig. 3), the transmission period of the CSI is smaller than the transmission period of the SRS, and then the CSI is allocated in the slot resource chain in the order of the CSI slot positions after allocating the slot position of the PUCCH resource for the SRS, and the next slot position is traversed if there is no PUCCH resource available in the current slot chain. In the second case (see b in fig. 3), if the CSI transmission period is greater than the SRS transmission period, and there may be a plurality of slot positions for allocating PUCCH resources to SRS in the CSI transmission period, traversing the slot positions for allocating PUCCH resources to SRS to the slot positions for CSI in the SRS transmission period, and selecting a slot position closest to the slot position for allocating PUCCH resources to SRS and having the largest idle PUCCH resources on the slot chain as the target slot.
S202, determining a linked list to which a target time slot of the CSI belongs and a target physical resource block PRB which is not occupied in the linked list and has the farthest distance with a channel PUSCH for transmitting service data.
The target PRB refers to PRB information corresponding to a PUCCH resource allocated for the CSI.
In an implementation, after determining the target slot, the target PRB may be determined. Specifically, first, a linked list to which the target timeslot belongs may be determined. Then, all unoccupied PRBs in the aforementioned linked list may be determined. Then, among all the unoccupied PRBs in the linked list, a PRB farthest from a PUSCH (Physical Uplink Shared Channel) may be selected, and the PRB farthest from the PUSCH may be determined as a target PRB.
S203, determining an unoccupied target symbol group with the minimum sequence number in the target PRB, and allocating physical uplink control channel PUCCH resources for the CSI based on the target time slot, the target PRB and the target symbol group.
And the target symbol group refers to a symbol group corresponding to a PUCCH resource allocated for the CSI.
In an implementation, after determining the target slot and the target PRB, a target symbol group may be determined. Specifically, first, all symbol groups corresponding to the target PRB may be determined, and an unoccupied symbol group may be determined in all the symbol groups. Then, the serial numbers corresponding to the unoccupied symbol groups may be obtained, and the symbol group with the smallest serial number may be determined as the target symbol group. Then, the time domain position of the PUCCH to be allocated for CSI may be determined based on the target slot and the target symbol, the time domain position of the PUCCH to be allocated for CSI and the PUCCH resource corresponding to the target PRB may be determined, and the PUCCH resource may be allocated to CSI, that is, used for transmitting CSI.
According to the technical scheme, the PUCCH resources are allocated to the CSI on the basis of the target time slot, the target PRB which is unoccupied in the linked list to which the target time slot belongs and has the farthest distance with the PUSCH and the target symbol group which is unoccupied in the target PRB and has the smallest sequence number are determined. Therefore, on one hand, PUCCH resources allocated for CSI can be more continuous, namely, frequency spectrum fragments can be reduced, so that when fewer access users exist, more unoccupied PUCCH resources allocated for CSI exist, and the part of the unoccupied PUCCH resources allocated for CSI and PUSCH resources are continuous, so that the PUSCH can utilize the part of the unoccupied PUCCH resources allocated for CSI to perform data transmission, the waste of the PUCCH resources can be effectively reduced, the peak speed of the user can be effectively improved, and the user experience is improved. On the other hand, in the method provided by the embodiment of the invention, the time slot is divided into a plurality of symbol groups, and when a plurality of access users exist, different symbol groups of the same time slot can be applied to different users, so that the utilization rate of PUCCH resources can be effectively increased, and the user capacity can be improved.
Further, on the basis of the above method embodiment, before allocating PUCCH resources for CSI, PUCCH resources may be reserved for CSI, and the corresponding processing may be as follows: acquiring the total number of PRBs occupied by PUCCH resources, wherein the total number of PRBs comprises a first PRB number allocated for scheduling request information SR and acknowledgement information ACK/NACK and a second PRB number allocated for CSI; and reserving PUCCH resources for the CSI based on the total number of PRBs, the first number of PRBs and the second number of PRBs.
In implementation, when a cell is established, the PUCCH resources may be reserved for CSI by integrating the configuration of an APM (Application Performance Management platform) and the allocation of other PUCCH resources in the cell. Specifically, the total number of PRBs occupied by the PUCCH resource configured by the management station may be obtained, and the number of PRBs allocated for SR and ACK/NACK (which may be referred to as a first number of PRBs) and the number of PRBs allocated for CSI (which may be referred to as a second number of PRBs) in the total number of PRBs may be determined. Then, PUCCH resources may be reserved for CSI based on the aforementioned total number of PRBs, the first number of PRBs, and the second number of PRBs. When the PUCCH resource is reserved, the total number of PRBs occupied by the PUCCH resource configured by the management station may be divided into an upper part and a lower part on average. The PUCCH resource for transmitting the SR is located on the RB closest to the lower edge of the frequency band, the PUCCH resource adjacent to the PUCCH resource for transmitting the SR is used for transmitting ACK/NACK, the PUCCH resource adjacent to the PUCCH resource for transmitting the ACK/NACK is used for transmitting CSI, and the PUCCH resource reserved for transmitting the CSI is close to the PUSCH. Therefore, PUCCH resources are reserved for CSI according to the total number of PRBs, the number of the first PRBs and the number of the second PRBs, the reserved PUCCH resources for transmitting the CSI are close to the PUSCH, and when the number of access users is small, the PUSCH can transmit data by using the unoccupied PUCCH resources allocated for the CSI, so that the waste of the PUCCH resources can be further reduced, the peak speed of the users can be further effectively improved, and the user experience can be improved.
Further, on the basis of the above method embodiment, PUCCH resources may be reserved for CSI according to a first ratio of the first PRB number to the total PRB number, and corresponding processing may be as follows: determining whether a first ratio of the first PRB number to the total PRB number is equal to a preset ratio or not; if the first ratio is equal to the preset ratio, determining whether a second ratio of the second PRB number to the total PRB number is smaller than the preset ratio; and if the second PRB number is smaller than the preset ratio, determining the upper edge of the PUCCH resources, and reserving the PUCCH resources for the CSI based on the upper edge and the second PRB number.
The first ratio refers to the ratio of the first PRB number to the total PRB number;
the second ratio refers to a ratio of a second number of PRBs to the total number of PRBs;
the preset ratio refers to a preset fixed ratio, and the ratio can be used as a data basis for reserving the PUCCH resources for the CSI.
In implementation, after acquiring the total number of PRBs, the first number of PRBs, and the second number of PRBs, a first ratio of the first preset number of PRBs to the total number of PRBs may be calculated, and it is determined whether the first ratio is equal to the preset ratio. If the first ratio is equal to the preset ratio, it may be further determined whether a second ratio between the second PRB number and the total PRB number is smaller than the preset ratio. If the second ratio is smaller than the preset ratio, an upper edge of the PUCCH resource may be determined, and the PUCCH resource is reserved for CSI based on the upper edge of the PUCCH resource and the second number of PRBs, referring to fig. 4, where CSI, PUSCH, ACK/NACK, and SR in fig. 4 respectively represent a PUCCH resource for transmitting CSI, a channel for transmitting traffic data, a PUCCH resource for transmitting ACK/NACK, and a PUCCH resource for transmitting SR, and may be arranged from the upper edge of the PUCCH resource (i.e., the upper edge of CSI in the figure) and downward next to the upper edge until the second number of PRBs is arranged, that is, the PUCCH resource reserved for CSI is arranged. And if the second ratio is greater than or equal to the preset ratio, confirming that the PUCCH resources are unsuccessfully reserved for the CSI, and failing to establish the cell. Therefore, the PUCCH resources which are close to the upper edge of the PUCCH resources are sequentially arranged downwards, the lower edge of the PUCCH resources reserved for the CSI is close to the PUSCH, so that when the number of accessed users of the PUSCH is small, the unoccupied PUCCH resources allocated for the CSI can be utilized for data transmission, the waste of the PUCCH resources is further reduced, the peak speed of the user is further effectively improved, and the user experience is improved.
It is understood that the meanings of CSI, PUSCH, ACK/NACK, SR in fig. 5-7 are the same as those in fig. 4.
Further, on the basis of the above method embodiment, PUCCH resources may be reserved for CSI when the first ratio is greater than the preset ratio, and the corresponding processing may be as follows: if the first ratio is not equal to the preset ratio, determining whether the first ratio is greater than the preset ratio; if the first ratio is larger than the preset ratio, determining whether the sum of the first PRB quantity and the second PRB quantity is smaller than the total PRB quantity; if the sum of the first PRB number and the second PRB number is smaller than the total PRB number, determining the upper edge of the PUCCH resource, and reserving the PUCCH resource for ACK/NACK based on the upper edge of the PUCCH resource and the first PRB number; and determining the lower edge of the PUCCH resource reserved for the ACK/NACK, and reserving the PUCCH resource for the CSI based on the lower edge of the PUCCH resource reserved for the ACK/NACK and the second PRB number.
In an implementation, if the first ratio is not equal to the preset ratio, it may be determined whether the first ratio is greater than the preset ratio. If the first ratio is greater than the preset ratio, the sum of the first PRB number and the second PRB number may be calculated, and it may be determined whether the sum is less than the total number of PRBs. If the sum of the first PRB number and the second PRB number is smaller than the total PRB number, the upper edge of the PUCCH resource can be determined, and the PUCCH resource can be reserved for ACK/NACK based on the upper edge of the PUCCH resource and the first PRB number. A lower edge of the PUCCH resource reserved for ACK/NACK may then be determined and PUCCH resources may be reserved for CSI based on the lower edge of the PUCCH resource reserved for ACK/NACK and the aforementioned second PRB number, as shown in fig. 5. Therefore, PUCCH resources corresponding to ACK/NACK are reserved to the upper edge of the PUCCH, PUCCH resources corresponding to CSI are reserved to be close to the PUSCH, when users have less access to the PUSCH, the PUSCH can more conveniently and rapidly utilize unoccupied PUCCH resources reserved for the CSI to carry out data transmission, and therefore peak speed and user experience of the users can be further improved.
Further, on the basis of the above method embodiment, when the first ratio is smaller than the preset ratio, PUCCH resources may be reserved for CSI, and the corresponding processing may be as follows: if the first ratio is smaller than the preset ratio, determining a third ratio of the sum of the first PRB quantity and the second PRB quantity to the total PRB quantity, and determining whether the third ratio is smaller than the preset ratio; if the third ratio is smaller than the preset ratio, determining the lower edge of the PUCCH resources, and reserving the PUCCH resources for SR and ACK/NACK on the basis of the lower edge of the PUCCH resources and the first PRB quantity; determining a lower edge of the PUCCH resources reserved for the SR and the ACK/NACK, and reserving the PUCCH resources for the CSI based on the lower edge of the PUCCH resources reserved for the SR and the ACK/NACK and the second PRB number.
The third ratio refers to a ratio of a sum of the first PRB number and the second PRB number to a total number of PRBs.
In an implementation, if the first ratio is smaller than the preset ratio, a sum of the first PRB number and the second PRB number and a third ratio of the sum to the total number of PRBs may be calculated, and whether the third ratio is smaller than the preset ratio may be determined. If the third ratio is smaller than the preset ratio, the lower edge of the PUCCH resource may be determined, and the PUCCH resource may be reserved for SR and ACK/NACK based on the lower edge of the PUCCH resource and the first PRB number. Then, a lower edge of PUCCH resources reserved for SR and ACK/NACK may be determined, and PUCCH resources may be reserved for CSI based on the lower edge of PUCCH resources reserved for SR and ACK/NACK and the second number of PRBs, as shown in fig. 6. Therefore, PUCCH resources corresponding to SR and ACK/NACK are reserved to the lower edge of PUCCH, PUCCH resources corresponding to CSI are reserved to be close to PUSCH, and when the user access is less, the PUSCH can more conveniently and rapidly utilize unoccupied PUCCH resources reserved for CSI to carry out data transmission, so that the peak speed of the user can be further improved, and the user experience can be further improved.
Further, on the basis of the above method embodiment, PUCCH resources may be reserved for CSI when the third ratio is greater than the preset ratio, and the corresponding processing may be as follows: if the third ratio is greater than the preset ratio, determining whether the sum of the first PRB quantity and the second PRB quantity is less than the total PRB quantity; if the sum of the first PRB number and the second PRB number is smaller than the total PRB number, determining the lower edge of the PUCCH resource, and reserving the PUCCH resource for SR and ACK/NACK on the basis of the lower edge of the PUCCH resource and the first PRB number; determining the lower edge of the PUCCH resources reserved for the SR and the ACK/NACK, reserving the PUCCH resources for the CSI based on the lower edge of the PUCCH resources reserved for the SR and the ACK/NACK and the second PRB number, and monitoring whether the ratio of the allocated PRB number to the total PRB number is equal to a preset ratio; and when the ratio of the number of the allocated PRBs to the total number of the PRBs is equal to a preset ratio, determining the upper edge of the PUCCH resource, and reserving the PUCCH resource for the CSI based on the number of the allocated PRBs, the first number of the PRBs and the upper edge of the PUCCH resource.
In an implementation, if the third ratio is greater than the preset ratio, it may be calculated whether a sum of the first PRB number and the second PRB number is smaller than the total number of PRBs. If the number of PRBs is less than the total number of PRBs, the lower edge of the PUCCH resource can be determined, and the PUCCH resource can be reserved for the SR and the ACK/NACK on the basis of the lower edge of the PUCCH resource and the first PRB resource. Then, the lower edge of the PUCCH resource allocated for SR and ACK/NACK may be determined, and the PUCCH resource may be reserved for CSI based on the determined lower edge of the PUCCH resource allocated for SR and ACK/NACK and the second PRB number, while it may be monitored whether the ratio of the allocated PRB number to the total number of PRBs is equal to the preset ratio. When the ratio of the number of the allocated PRBs to the total number of the PRBs is monitored to be equal to a preset ratio, the upper edge of the PUCCH resource can be determined, and the PUCCH resource is reserved for the CSI based on the number of the allocated PRBs, the first number of the PRBs and the upper edge of the PUCCH resource. As shown in fig. 7, the PUCCH resources reserved for CSI may be divided into two parts: one part of the resource is reserved at the lower half part of the PUCCH resource and is arranged upwards close to the upper edge of the ACK/NACK resource until the PRBs are obtained by multiplying the preset ratio by the total number of the PRBs; and the other part is reserved in the upper half part of the PUCCH resources and is arranged from the upper edge of the bandwidth to the lower part until the second PRB quantity of PRBs is arranged. Therefore, the PUCCH resources reserved for the CSI in the upper part and the lower part are continuously reserved close to the PUSCH, so that the PUSCH can more conveniently and rapidly call the unoccupied PUCCH resources reserved for the CSI, and the user experience can not be further improved.
It can be understood that, in other cases where the above condition is not satisfied, it may be considered that the PUCCH resource reservation for CSI fails, and the cell establishment fails.
Further, on the basis of the above method embodiment, the symbols in each slot may be grouped, and the corresponding processing may be as follows: determining the uplink control information UCI bit number which needs to be carried by CSI and the symbol number which needs to be carried by the UCI bit number, and determining whether the symbol number is less than or equal to a first preset symbol number; if the number of the symbols is less than or equal to a first preset number of the symbols, grouping all the symbols corresponding to the current time slot according to a first preset grouping format, and setting a serial number for each grouped symbol group according to a grouping sequence; if the number of the symbols is larger than the first preset number of the symbols, determining whether the number of the symbols is smaller than or equal to a second preset number of the symbols; if the number of the symbols is less than or equal to a second preset number of the symbols, grouping all the symbols corresponding to the current time slot according to a second preset grouping format, and setting a serial number for each grouped symbol group according to a grouping sequence; and if the number of the symbols is greater than a second preset number of the symbols, dividing the current time slot into a symbol group.
The first/second/third preset grouping formats respectively refer to three preset different grouping formats for grouping the symbols, and the corresponding first/second preset symbol numbers refer to data bases for determining which preset grouping format is adopted.
In implementation, after the PUCCH resource is reserved for CSI, symbols of each slot corresponding to the PUCCH resource reserved for CSI may be grouped, specifically, first, the number of UCI (Uplink Control Information) bits that the CSI needs to carry may be determined, and the number of symbols (such as Format3 symbols) that the number of UCI bits needs to carry may be determined. The number of symbols may then be compared to a first predetermined number of symbols to determine whether the number of symbols is less than or equal to the first predetermined number of symbols. If the number of the symbols is less than or equal to a first preset number of symbols, all symbols corresponding to the current time slot are grouped according to a first preset grouping format, and a serial number can be set for each grouped symbol group according to a grouping sequence. If the number of symbols is greater than a first predetermined number of symbols, it may be determined whether the number of symbols is less than or equal to a second predetermined number of symbols. If the number of the symbols is less than or equal to a second preset number of symbols, grouping all symbols corresponding to the current time slot according to a second preset grouping format, and setting a serial number for each grouped symbol group according to a grouping sequence. If the number of symbols is greater than a second preset number of symbols, the current time slot may be divided into a symbol group, that is, all symbols in one time slot are a symbol group.
Taking the total 14 Format3 symbols in the current time slot, the first predetermined packet Format being 4/4/6, the second predetermined packet Format being 7/7, and the third predetermined packet Format being 14 as examples, it may be determined that the first predetermined number of symbols is 4 and the second predetermined number of symbols is 7. Assuming that the number of UCI bits to be carried can be carried by using 4 or less Format3 symbols, a first preset grouping Format 4/4/6 is used to divide a slot into three symbol groups, and a sequence number is set for each symbol group according to a grouping order, for example, a symbol group 1 includes 4 Format3 symbols, a symbol group 2 includes 4 Format3 symbols, and a symbol group 3 includes 6 Format3 symbols; assuming that the number of UCI bits to be carried can be carried by using 5-7 Format3 symbols, a slot is divided into two symbol groups by using a division manner of a second preset packet Format 7/7, for example, a symbol group 1 includes 7 Format3 symbols, and a symbol group 2 includes 7 Format3 symbols; assuming that the number of UCI bits to be carried is carried using 8-14 Format3 symbols, a time slot is divided into a symbol group using a third predetermined packet Format. Therefore, different dividing modes can be selected to divide the symbol groups according to actual needs, symbols of the same time slot are divided into a plurality of symbol groups, time slot multiplexing can be achieved, namely the same time slot can be used by a plurality of users, and therefore user capacity can be further improved.
It is to be appreciated that after symbol group division is performed on symbols within a slot, a linked list of PUCCH resources allocated for CSI may be initialized. As shown in fig. 8, first, the number M of PUCCH resources allocated to CSI supported by a cell may be calculated according to APM configuration, then, the number S of available uplink timeslots in each CSI transmission period may be calculated according to CSI transmission period configuration and uplink and downlink timeslot ratio of the cell, each uplink timeslot in the CSI transmission period is initialized to a CSI resource linked list, and M PUCCH resources allocated to CSI are averagely allocated to the CSI resource linked lists of S timeslots. This part is similar to the existing algorithm in the prior art, and is different in that when a single CSI resource linked list is used to arrange each PUCCH resource node, in addition to considering the PRB positions of the resource nodes, it is also necessary to consider the dimension of the symbol group to which the resource nodes belong: when each CSI resource linked list is arranged, the nodes are arranged according to the sequence of PRB from small to large, the resource nodes with smaller PRB are arranged in front of the linked list, in one PRB, the nodes are arranged according to the sequence of symbol group sequence numbers from front to back, the nodes with smaller symbol group sequence numbers are arranged in front of the linked list, when the resource nodes in one PRB are arranged, the next PRB is arranged, in the arranging process, the position of the PRB where the node is located and the symbol group sequence number are recorded in each node of the CSI resource linked list, all the resource nodes are set to be in an idle state, and preparation is made for subsequent distribution.
