Technical Field
The present invention relates to the field of communications, and in particular, to a parameter sending method, a resource determining method, a parameter sending device, a resource determining device, a base station, and a terminal.
Background
A New generation mobile communication system (New Radio, abbreviated as NR) is being researched, and in the NR system that can be determined at present, there are 3 typical service types in the future. Common services include: enhanced Mobile BroadBand (eMBB), high-reliability and Low-Latency Communications (URLLC), and massive Machine Type Communications (mMTC). These services have different requirements with respect to delay, coverage and reliability. For example, for the eMBB, high peak transmission rate is mainly emphasized, the requirement on delay is not high (low delay is not required), and the reliability is required. For URLLC, low latency, high reliability transmission is emphasized, which is very demanding on latency. For mtc, a large number of terminals are emphasized, the connection density is high, and a larger transmission coverage is required, and there is little requirement for delay.
In the NR system, a Physical Resource Block (PRB) is still used for Resource allocation. Currently, a PRB Frequency domain includes 12 subcarriers, and the number of Orthogonal Frequency Division Multiplexing (OFDM) symbols included in a time domain is not determined. It is assumed that the number of symbols included in the time domain is the same as the number of OFDM symbols included in a scheduling unit (for example, a slot, which may also be regarded as a scheduling unit).
An Uplink Control Channel (e.g., a Physical Uplink Control Channel (PUCCH)) of a receiving end (e.g., a User Equipment (UE)) may be configured with multiple candidate resources, where the multiple candidate resources configured in the related art are fixed, so that the candidate resources may not be matched with transmission bits when transmission bits change.
In view of the above technical problems in the related art, no effective solution has been proposed at present.

5. Based on 1, the base station configures the value of Q and sends the value to UE through high-level signaling or physical layer signaling;
or, when the base station and the UE always require each resource to include a fixed PRB, then the Q value is agreed in advance;

Or, the high-level signaling configures the Q value, but the base station can send the physical-level signaling reconfiguration Q value to be valid at the time, and then the Q value configured by the high-level signaling is still considered to be valid.
6. Based on 1, the Q, the base station and the UE agree on the directionality of the Q, namely when the number num of each resource is an odd number, the Q calculates the PRBs contained in each resource in the direction of increasing the PRB index; when the number num is even, Q calculates PRBs included in each resource in a direction in which the PRB index decreases.

8. Based on 1, when the base station allocates resources for the UE, the base station always preferentially configures PRBoffset from small to large. For example, PRBoffset is increased when the resource allocation corresponding to a certain small PRBoffset cannot be reallocated to more UEs.

Figure BDA0001221121110000511
PRBnumafter being calculated, Q PRBs are calculated according to a rule as the PRBs contained in each resource.
The preferred embodiment of the present invention provides a method for configuring a suitable uplink control symbol position for a UE according to a beam direction of the UE when short uplink control time division multiplexing of different UEs is performed in one transmission unit, so that transmission of the UE and reception of a base station are simpler.
In a preferred embodiment of the present invention, referring to equation 1 below, a sending end and a receiving end agree or a sending end signaling indicates a value of a relevant parameter, and then calculates allocated resources according to an agreed rule. And the values, configuration and usage of the relevant parameters, and the resource allocation use case based on the variant of equation 1. The UE is dynamically informed that the size of each candidate PUCCH resource is a dynamic size that is applicable to the PUCCH load.
Even if the candidate PUCCH resource allocation scheme in the ARI mechanism of the existing LTE is used, a new parameter describing an increased number of PRBs per candidate PUCCH resource or PUCCH resource (from the candidate PUCCH resource) specifically used by the UE based on the candidate PUCCH resource allocation in the existing ARI mechanism needs to be additionally introduced.
Fig. 14 is a schematic diagram of a resource allocation situation provided according to a preferred embodiment of the present invention, and referring to fig. 14 and equation 1, a sending end (which may be a base station, a small cell base station, a remote radio unit, etc., and will be described below by taking a base station as an example) and a receiving end (which may be a UE, a terminal, etc., and will be described below by taking a UE as an example) agree on or send end signaling to indicate a relevant parameter value, and then calculate allocated resources (which may be in the form of a PRB or a cluster, and mainly includes granularity of frequency domain resources, and will be described below by taking a PRB as an example) according to an agreed rule.
The required relevant parameters include:
PRBallobtaining the total PRB number, for example, the total PRB number is 110, the index is 0-109, then PRBallThen 109. All allocated PRBs may be allowed, for example, all PRBs corresponding to the system bandwidth, or the sum of all PRBs corresponding to one or more subbands in the system bandwidth; if the plurality of sub-bands are discrete, the sum of the PRBs of the plurality of discrete sub-bands is used as the total number of PRBs, or resource allocation is independently carried out according to each sub-band, and the PRB corresponding to each sub-band is used as the total number of PRBs.
PRBoffsetThe number of offset PRBs relative to the minimum index PRBs of the total PRBs. For example, the total PRB number is 110, the index is 0-109, and then PRBoffsetIt is how many PRBs are offset from the PRB index 0. Or as an offset from the starting PRB of the PRB index 0.
And M is the number of resources needing to be allocated.
PRBnumStarting PRB index of allocated resource. num is the number of one resource and is from 0 to M-1.
Q is the number of PRBs contained in each resource, according to the PRBsnumThe corresponding PRBs are calculated in a direction of increasing or decreasing (in different cases, increasing or decreasing) the indexes of the corresponding PRBs.
An example is given below to illustrate the use of the above parameters, equation 1 is an example constructed by the above parameters, and based on this equation 1, the corresponding resource allocation can be achieved.
Figure BDA0001221121110000521
In addition, specific applications including improved use of the above-described related parameters or equation 1 will be given in the present invention. The problems to be solved in different applications or improvements are different, and the effects to be achieved are different. Therefore, there are many variables for the specific use of the relevant parameters. Specific uses to solve various problems are listed in detail below.
In equation 1, PRBoffsetIs a starting offset, less than or equal to PRB with PRB index of 0
Figure BDA0001221121110000522
The resulting value of (this is to avoid overlapping of allocated PUCCH resources, if overlapping is allowed or M is small, PRBoffsetThe maximum value is 109). When the total number of PRBs is determined, the required number of copies is determined, and the range of PRBoffset can be obtained.
In the case of the equation 1,
Figure BDA0001221121110000531
the rounding-down is one of the methods, and the rounding-up or rounding-down principle can also be adopted.
The specific use of Q is when PRBnumAfter being calculated, Q PRBs are calculated according to the rule convention sequence as the PRBs contained in each resource.
Preferred embodiment 1, use of equation 1.
It is assumed that the system bandwidth is 20M, corresponding to 110 PRBs, and the index value ranges from 0 to 109, and 4 candidate PUCCH resources are allocated to one UE, where each candidate PUCCH resource includes 2 PRBs and requires 2 consecutive PRBs.
The base station configures the UE to use the whole system bandwidth, so that the total PRBs are 110, the index value range is 0-109, namely the PRball value is 109.
The value of the base station configuration Q is 2, and the Q is sent to the UE through a high-level signaling or a physical layer signaling, or is about to be 2. When the base station and the UE always require each candidate PUCCH resource to contain 2 PRBs, then the Q value may be agreed to be 2 in advance; when the number of PRBs contained in each candidate PUCCH resource required by the base station and the UE changes slowly, the Q value can be configured through high-level signaling. In addition, the following manner may also be adopted, for example, when the Q value is configured for the higher layer signaling, but the Q value needs to be adjusted temporarily, the base station may send the physical layer signaling reconfiguration Q value as being valid again, and then the Q value configured for the higher layer signaling is still considered to be valid. Further, in the preferred embodiment 1, the base station and the UE agree on the directionality of Q, that is, when num is an odd number, Q calculates the PRBs included in each candidate PUCCH in the direction of increasing PRB index, and when num is an even number, Q calculates the PRBs included in each candidate PUCCH in the direction of decreasing PRB index. The directionality of Q may be predetermined, and different directivities of Q will result in different assignments.
The base station configures the value of M to be 4, and sends the value to the UE through a high-layer signaling or a physical layer signaling, or the value is about 4. When the UE always needs 4 candidate PUCCH resources, then the value of M may be agreed to 4 in advance; when the number of the candidate PUCCH resources required by the UE changes slowly, the M value can be configured through high-level signaling. In addition, the following manner may also be adopted, for example, the higher layer signaling configures the M value, but when the adjustment is temporarily needed, the base station may send the physical layer signaling reconfiguration M value to be valid next time, and then still consider that the M value configured by the higher layer signaling is valid.
The base station configures the value of PRBoffset to be 2 and sends the value to the UE through high-level signaling or physical layer signaling. At this time, is less than or equal to
Figure BDA0001221121110000541
The obtained value of (a).
The number corresponding to the M candidate PUCCH resources is denoted num, and the corresponding values are 0,1,2, and 3.
Then substituting the above parameters into equation 1, the starting PRB index of each candidate PUCCH resource can be obtained:
PRBnum＝0＝2,PRBnum＝2＝29,PRBnum＝1＝107,PRBnum＝3＝80。
further, combining the directionality of Q agreed by the base station and the UE, it may be obtained that the PRB index included in the candidate PUCCH resource with the number num ═ 0 is 2, 3; the PRB index included in the candidate PUCCH resource numbered num ═ 2 is 29, 30; the candidate PUCCH resource numbered num 1 includes a PRB index of 79, 80; the candidate PUCCH resource numbered num 3 includes a PRB index of 106,107.
In the preferred embodiment 1, the candidate PUCCH resources are always allocated from both ends of the system bandwidth. By adopting the method of the preferred embodiment 1, compared with directly notifying the PRB index of each candidate PUCCH resource, the method has the advantage of low overhead, and the number and the position of PRBs included in each candidate PUCCH resource can be flexibly adjusted.
Currently, in the NR, the range of effective bits of the PUCCH is considered to be increased relative to the LTE system, for example, the effective bits carried by the PUCCH channel have a large variation range, and for example, companies propose that the effective bits variation range is as follows: the short PUCCH bits are 1-64 bits, the long PUCCH bits are 1-640 bits, and the change of the bit number is dynamic. If this proposal is adopted by NR, it is difficult to implement purely by multiplexing in order to support such a large effective bit variation range, so a dynamic addition of PUCCH resources would be necessary, how could it be increased? On the basis of the preferred embodiment 1, as long as the base station dynamically configures the value of Q through signaling, it can implement that the PUCCH resource size of the UE is dynamically changed in each scheduling unit, for example, downlink control information DCI of scheduling data is used to carry Q (in this document, parameters using physical layer signaling may all be carried using DCI). For example, the PUCCH of the UE in scheduling unit n needs 2 PRBs, and then the base station configures the Q value in the DCI in scheduling unit n to be 2, and the PUCCH of the UE in the next scheduling unit n needs 10 PRBs, and then the base station configures the Q value in the DCI in scheduling unit n +1 to be 10. In the conventional LTE, the size of each candidate PUCCH resource cannot be dynamically modulated, and the number of effective bits of the PUCCH is basically fixed, so that it is not necessary to adjust the resource size.
Currently, in NR, in the latest discussion, frequency division multiplexing of PUSCH and short PUCCH is supported (short PUCCH is PUCCH transmitted in several symbols before uplink data or at the end of a scheduling unit, and the typical number of symbols is 1 symbol), so as to enable UE to know that PRBs in the system bandwidth are allocated to a candidate PUCCH, when PUSCH of UE is included in these PRBs, the symbol occupied by PUCCH is avoided. In preferred embodiment 1, the base station can gradually increase the PRBoffset value from 0, for example, first allocate a value of PRBoffset equal to 0 to the UE, and if there is still UE that needs to be allocated, continue to use PRBoffset equal to 1, and so on, only the current PRBoffset value is allocated to reuse the next PRBoffset value, so that the base station can broadcast the maximum value in PRBoffset corresponding to the PUCCH allocation resource in the system to the UE, so that the UE will know that PRBs in the system are allocated as PUCCH resources according to equation 1 and related parameters, such as Q and M (Q, M also needs to be broadcast to the UE if it changes slowly).
Obviously, in the preferred embodiment 1, the candidate PUCCH resource allocation method may also be regarded as PRB resource allocation, and may be used for PRB allocation for other purposes. For example, when one UE needs 2 PRBs, different PRB allocation patterns may be implemented by configuring values of relevant parameters, some examples are as follows:
setting M to be 2 and num to be 0, 1; q is 1; PRBoffset ═ 0; the allocated PRB index is: 0,109. This results in discrete PRB resources.
Setting M to be 2 and num to be 0, 1; q is 1; PRBoffset 4; the allocated PRB index is: 4,105. This results in discrete PRB resources.
Setting M to be 1 and num to be 0; q is 2; PRBoffset ═ 0; the allocated PRB index is: 0,1. This results in contiguous PRB resources.
Setting M to be 1 and num to be 0; q is 2; PRBoffset 4; the allocated PRB index is: 4,5. This results in contiguous PRB resources.
In one particular preferred embodiment 1.1,
in the preferred embodiment 1.1, it can be assumed that the base station obtains each candidate PUCCH resource by non-equation 1 (the number of PRBs in each candidate PUCCH resource is 1), for example, in the LTE system, the base station directly notifies the UE of the starting PRB index of each candidate PUCCH resource, for example, through higher layer signaling or physical layer signaling. To support a wide range of dynamic effective bit numbers, an improvement is presented herein. For example, new signaling is introduced, describing that consecutive P PRBs are taken as each PUCCH candidate resource, indexed from the starting PRB. P can be dynamically configured by the base station and sent to the UE, e.g., a DCI bearer. The base station and the UE appoint that P PRBs are sequentially added (in the direction of increasing or decreasing the index) to serve as the PRBs of the current candidate PUCCH resource on the basis of the allocated PRBs of each candidate PUCCH resource. P can be notified directly or implicitly, and in short, P describes the number of PRBs that needs to be additionally increased this time.
Preferred embodiment 2
In order to discretize the PRBs for each candidate PUCCH resource. The total required PRBs are allocated by using equation 1, and then the candidate PUCCH resource to which the obtained PRBs belong is subdivided. The method is divided into two variations.
Preferred embodiment 2.1, when on the basis of equation 1, assuming that each candidate PUCCH resource includes Q1 PRBs, assuming that M1 candidate PUCCH resources are configured, the total number of PRBs required to be allocated is Q1xM 1. Q1xM1 PRBs are then allocated using equation 1 above. At this time, the meaning of the corresponding part of the parameters in equation 1 will change. E.g. M, Q, PRBnumMeaning changes will occur (or it can be understood that the PRB is temporarily allocated according to the original meaning, and finally the candidate PUCCH resource to which the obtained PRB belongs needs to be re-partitioned again). At this time, the three parameters can be regarded as 3 intermediate variable parameters. The meaning of the remaining parameters is unchanged.
For convenience of explanation, the following is exemplified. Assume that 4 candidate PUCCH resources still need to be allocated for the UE, but each resource contains 2 discrete PRBs. The rest of the assumptions are the same as in preferred embodiment 1.
The base station configuration parameter value is Q1, M Q1xM 12 x4 (the values of Q and M always assume that each candidate PUCCH has only one PRB and always requires 8 candidate PUCCH resources, after 8 PRBs are obtained through equation 1, the 8 PRBs are re-divided as the PRB of each candidate PUCCH resource), and the PRB is sent to the UE, and the parameter PRBnum is calculated by using equation 1 in agreement with the UE. Thus, PRBnum ═ 0 ═ 2, PRBnum ═ 2 ═ 15, PRBnum ═ 4 ═ 28, PRBnum ═ 6 ═ 41, PRBnum ═ 1 ═ 107, PRBnum ═ 3 ═ 94, PRBnum ═ 5 ═ 81, and PRBnum ═ 7 ═ 68.
Further, combining Q (final Q requirement, in this case, Q is 2, but not 1 of the middle procedure) PRBnum (which may be only even or odd) with even and odd num corresponding to Q PRBs in each candidate PUCCH resource agreed by the base station and the UE. And finally, obtaining Q PRBs in each candidate PUCCH resource from the candidate PUCCH resources corresponding to the PRBnum obtained by the equation 1. For example, the PRBnum ═ 0 and PRBnum ═ 1 obtained in equation 1 above are one set of candidate PUCCH resources, PRBnum ═ 2 and PRBnum ═ 3 are one set of candidate PUCCH resources, PRBnum ═ 4 and PRBnum ═ 5 are one set of candidate PUCCH resources, and PRBnum ═ 6 and PRBnum ═ 7 are one set of candidate PUCCH resources.
At this time, the 4 candidate PUCCH resources allocated to the UE are: PRB index 2,107; PRB index 15, 94; PRB index 28, 81; PRB indices are 41, 68.
Preferred embodiment 2.2, when on the basis of equation 1, assuming that each candidate PUCCH resource includes Q1 PRBs, assuming that M1 candidate PUCCH resources are configured, the total number of PRBs required to be allocated is Q1xM 1. Q1xM1 PRBs are then allocated using equation 1 above. At this time, the meaning of the corresponding part of the parameters in equation 1 will change. For example, M, Q, PRBnum will change meaning (or it can be understood that PRB is allocated temporarily according to the original meaning, and finally the candidate PUCCH resource to which the obtained PRB belongs needs to be re-partitioned again). In this case, the 3 parameters can be regarded as 3 intermediate variable parameters. The remaining parameters have unchanged meaning.
For convenience of explanation, the following is exemplified. Assume that 4 candidate PUCCH resources still need to be allocated for the UE, but each resource contains 2 discrete PRBs. The rest of the assumptions are the same as in preferred embodiment 1.
The base station configuration parameter value is Q4, M2 (the values of Q and M always assume that each candidate PUCCH has 4 PRBs, and 2 candidate PUCCH resources are always needed, 8 PRBs are obtained through equation 1, then the 8 PRBs are re-divided as the PRBs of each candidate PUCCH resource, and the PRBnum is sent to the UE, and meanwhile, the PRBnum is calculated by using equation 1 in agreement with the UE. Thus, PRBnum ═ 0 ═ 2, and PRBnum ═ 1 ═ 107. At this time, the candidate PUCCH resource corresponding to PRBnum ═ 0 is temporarily 2,3,4, 5. The candidate PUCCH resource corresponding to PRBnum ═ 1 is temporarily 104,105,106,107.
Further, in each candidate PUCCH resource agreed by the base station and the UE, Q (final Q requirement, in this case, Q is 2, but not 4 of the middle procedure) is associated with one PRB including num (in this variation, num of the middle procedure, i.e. 0,1) of even and odd PRBnum (which may be only even or odd). And finally, obtaining Q PRBs in each candidate PUCCH resource from the candidate PUCCH resources corresponding to the PRBnum obtained by the equation 1. For example, it is agreed (the rule may be defined according to actual needs), where the 1 st PRB in the PRBnum ═ 0 and the 1 st last PRB in the PRBnum ═ 1 obtained in the above equation 1 are one set of candidate PUCCH resources, the 2 nd PRB in the PRBnum ═ 0 and the 2 nd last PRB in the PRBnum ═ 1 are one set of candidate PUCCH resources, the 3 rd PRB in the PRBnum ═ 0 and the 3 rd last PRB in the PRBnum ═ 1 are one set of candidate PUCCH resources, and the 4 th PRB in the PRBnum ═ 0 and the 4 th last PRB in the PRBnum ═ 1 are one set of candidate PUCCH resources.
At this time, the 4 candidate PUCCH resources allocated to the UE are: PRB index 2,107; PRB index 3,106; PRB index 4,105; PRB index is 5,104.
Preferred embodiment 3
Fig. 15 is a schematic diagram of sub-band resource allocation according to preferred embodiment 3 of the present invention, and mainly describes a case when the base station allocates resources only to a part of the system bandwidth, for example, a sub-band, or multiple sub-bands, with reference to fig. 15. For example, a 100M system bandwidth, divided into 5 20M subbands, is now allocated resources within one or more subbands.
For the case of allocation for only one subband, the PRBs within the subband may be renumbered, allocated as in preferred embodiments 1 and 2. Or equivalently increasing the parameter value in the preferred embodiments 1 and 2 to a constant value, where the constant value is the minimum PRB index value of the subband where the parameter value is located. At this time, the base station needs to allocate a corresponding sub-band for the UE first, and then perform resource allocation within the sub-band according to the convention by using the preferred embodiments 1 and 2.
If the sub-band allocated to the UE by the base station is a continuous plurality of sub-bands, it can still be regarded as one sub-band for processing.
If the sub-band allocated by the base station for the UE is a plurality of discrete sub-bands, PRBs in the plurality of sub-bands are renumbered and then treated as one sub-band.
Preferred embodiment 4
The preferred embodiment provides a specific method for indicating candidate resources (e.g. PUCCH candidate resources), which is used in a slot (or subframe, etc.) that is used for transmitting downlink data but in which there is a resource for UE to transmit uplink data or control. Generally, there is downlink control information at the beginning of the time slot, and the downlink control information may be used to schedule downlink data in the time slot (note that downlink data in the time slot may also be scheduled by downlink control information in a previous time slot). If multiple candidate resources exist in the time slot as the UE and it needs to be indicated that the candidate resources in the time slot will be used specifically by the UE, the base station can indicate the candidate resources used specifically by the UE in the time slot for the UE by transmitting downlink control information (downlink grant information) corresponding to downlink data of the UE in the time slot. Note that it is emphasized herein that the downlink control information is sent in the time slot, i.e. candidate resources for specific use by the UE in the time slot are indicated in the time slot. In addition, it is emphasized herein that downlink data corresponding to downlink control information carrying candidate resources specifically used by the UE in the time slot is transmitted in the time slot (the downlink control information may be transmitted in a certain previous time slot).
In an uplink timeslot, downlink control information (for uplink data scheduling or for downlink data scheduling across timeslots) may start at the beginning of the uplink timeslot, followed by an uplink data transmission portion and an uplink control region. If the UE needs to use the specific candidate resource to carry data in the time slot, the base station can send a signaling indicating the specific candidate resource for the UE in the downlink control information (i.e. uplink grant information for scheduling uplink data) of the time slot. That is, the UE receives the uplink grant information in the time slot, schedules uplink data, and obtains specific candidate resource information used in the time slot.
This indication can solve the following problem, if the time slot is a time slot mainly for downlink data, at this time, downlink control information is not sent in the time slot for uplink data scheduling. If the specifically used candidate resource is carried by the downlink control information scheduled for the uplink data, the UE will not receive the signaling indicating the specifically used candidate resource in the time slot.
It will be apparent to those skilled in the art that the modules or steps of the present invention described above may be implemented by a general purpose computing device, they may be centralized on a single computing device or distributed across a network of multiple computing devices, and alternatively, they may be implemented by program code executable by a computing device, such that they may be stored in a storage device and executed by a computing device, and in some cases, the steps shown or described may be performed in an order different than that described herein, or they may be separately fabricated into individual integrated circuit modules, or multiple ones of them may be fabricated into a single integrated circuit module.
