Description

Transmission resource selection method and device
Technical Field
The present disclosure relates to the field of communications, and in particular, to a method and an apparatus for selecting transmission resources.
Background
Currently, the fourth Generation mobile communication technology (the 4th Generation mobile communication technology, 4 g) Long-Term Evolution (LTE)/Long-Term Evolution advanced (LTE-a) and the fifth Generation mobile communication technology (the 5th Generation mobile communication technology,5 g) face more and more demands. From the current development trend, 4G and 5G systems are researching and supporting the characteristics of mobile broadband enhancement, ultrahigh reliability, ultralow time delay transmission and massive connection.
In order to support the characteristics of ultra-high reliability and ultra-low delay transmission, it is necessary to transmit a low-delay and high-reliability service in a short transmission time, and meanwhile, in the process that other services with longer transmission time are not transmitted or are being transmitted, part of resource process transmission can be preempted. Because the transmission of the upstream transmission is not clearly preempted among different users, in order to reduce the performance influence on the service with high reliability and low delay as much as possible, the preemption indication information needs to be notified to the user who is preempted to transmit, at this moment, the transmission of the service with longer transmission time interval or the upstream transmission of the service with lower reliability is cancelled or stopped, and further, the performance reduction caused by the simultaneous transmission on the same resource with the low delay and high reliability service is avoided. Currently, for downlink traffic, preemption transmission is to divide 14 blocks in configured reference downlink resources by { M, N } = {14,1} or {7,2}, and notify whether each block is preempted or not in a bitmap manner, where M represents the number of time-domain divided blocks and N represents the number of frequency-domain divided blocks. Uplink transmission does not have an efficient indication means.
In addition, uplink transmission includes two types: scheduling based (grant based) uplink transmission and scheduling free (grant free) uplink transmission. The grant based uplink transmission refers to uplink service transmission performed by a user according to uplink authorization of a base station, and its transmission resource is determined. And the grant free uplink transmission refers to uplink traffic transmission which is autonomously selected by a user on a group of semi-statically configured grant free resources. For this type of transmission, the base station cannot predetermine on which candidate resource a particular transmission occurs. Therefore, when the scheduling-free service uplink transmission overlaps with the transmission resources of other low-priority users, the base station cannot notify the preempted users in advance, and therefore, the reliability of the scheduling-free service transmission cannot be ensured, and the transmission resource multiplexing of the scheduling service and the scheduling-free service cannot be realized.

In this embodiment, a method for selecting uplink transmission resources operating in the mobile terminal is provided, and fig. 2 is a flowchart of uplink transmission resource selection according to an embodiment of the present disclosure, and as shown in fig. 2, the flowchart includes the following steps:
step S202, UE receives indication information of a first resource set and indication information of a second resource set, wherein the first resource set is a set of uplink service transmission resources configured for the UE by a base station side, and the second resource set is a set of limited transmission resources of the uplink service;
step S204, the UE determines an uplink transmission strategy according to the indication information of the first resource set and the indication information of the second resource set.
In this embodiment, the first resource set may be a set of uplink scheduling-free resources or a set of uplink grant transmission resources; the second set of resources is a set of resources for uplink grant transmissions that have been allocated to other UEs in the reference uplink resources. The limited transmission resource of the uplink service may include a resource that cannot be occupied by the uplink service transmission or a resource that requires adjustment of transmission power transmission.
In step S202, the first resource set may be indicated by physical layer signaling, or indicated by high layer signaling, or indicated by a combination of high layer signaling and physical layer signaling; the second set of resources may be indicated by physical layer signaling.
In the above embodiment, the first set of resources comprises one of: a primary non-scheduled resource and one or more secondary non-scheduled resources, wherein the primary non-scheduled resource has a higher priority than the secondary non-scheduled resource; a primary schedule-free resource and a shared schedule-free resource, wherein the primary schedule-free resource has a higher priority than the shared schedule-free resource; the scheduling-free resources are shared.
In the above step S202, the indication information of the second resource set indicates the resources that have been allocated to the scheduling service in the RUR by one of the following manners: dividing RUR into N DCI_bit Each bit in the indication information of the second resource set indicates the occupied condition of one sub-resource block, wherein N is DCI_bit Indicating the number of bits in the information for the second resource; dividing the RUR into P × q sub-resource blocks, wherein each bit in the indication information in the second resource set indicates the occupied condition of one sub-resource block, P is the number of sub-bands divided by the whole uplink BWP in a frequency domain, and q is the number of symbols in the RUR or the number of mini-slots in the RUR.
In step S204, the UE may determine the uplink transmission policy as follows:
if the main scheduling-free resource and the second resource set do not have intersection, the UE selects the main scheduling-free resource as a transmission resource of a scheduling-free service;
if the primary scheduling-free resource and the second resource set have an intersection, the UE selects an auxiliary scheduling-free resource which does not have an intersection with the second resource set as a transmission resource of a scheduling-free service;
if the main scheduling-free resource and the auxiliary scheduling-free resource are intersected with the second resource set, if the number of idle RBs outside the second resource set in BWP is larger than or equal to the number of RBs required by scheduling-free service transmission, selecting the RBs in the idle RBs as the transmission resources of the scheduling-free service;
if the main scheduling-free resource and the auxiliary scheduling-free resource are intersected with the second resource set, if the number of idle RBs outside the second resource set in BWP is less than the number of RBs required by the scheduling-free service transmission, the UE selects all idle RBs, and selects the number of residual RBs in the range of all non-idle RBs as the transmission resource of the scheduling-free service;
and if the resources in the first resource set used for the transmission of the scheduling-free service and the second resource set have overlapped resources, the UE raises the power for transmitting the scheduling-free service.
If the main scheduling-free resource and the second resource set have an intersection, and the idle number without the intersection with the second resource set in the shared scheduling-free resource is more than or equal to the number of RBs required by the scheduling-free service transmission, selecting the RBs in the idle RBs of the shared scheduling-free resource as the transmission resources of the scheduling-free service;
if the main scheduling-free resource and the second resource set have intersection, and the idle number without intersection with the second resource set in the shared scheduling-free resource is less than the number of RBs required by the transmission of the scheduling-free service, all idle RBs of the shared scheduling-free resource are selected, and the remaining number of RBs is selected in all non-idle RB ranges of the shared scheduling-free resource to serve as the transmission resource of the scheduling-free service.
In the above embodiment, the ratio of the overlapping resources to the resources required for the scheduling-free service transmission may be determined first, and the transmission power of the scheduling-free service is increased to a corresponding level according to the ratio. The UE may increase the power for transmitting the non-scheduling service on the overlapping resources, or the UE may increase the power for transmitting the non-scheduling service on all resources occupied by the non-scheduling service transmission.
In the above embodiment, the UE may determine the resource ultimately occupied by the scheduling-free uplink transmission of the scheduling-free service according to the situation that the scheduling-free resource is occupied by the scheduling resource, and the transmission mechanism, so that multiplexing between the scheduling-free uplink transmission of the scheduling-free service and the uplink transmission of the authorization service may be effectively implemented, resource conflict of the scheduling-free uplink transmission of the scheduling-free service is reduced, and resource utilization efficiency is improved.
The uplink transmission resource selection method provided by the present disclosure will be further described below by specific embodiments.
Example 1
The configuration method of the first resource set is described in this embodiment. The first resource set is a resource pre-configured for grant free uplink transmission, and the network side indicates the first resource set to the terminal through first resource indication information, preferably, the first resource indication information is indicated through a high layer signaling (such as an RRC signaling) or indicated through a combination of the high layer signaling and a physical layer signaling. There are several configurations as follows:
the first method is as follows:
and configuring a main grant free resource and one or more auxiliary grant free resources for each grant free UE. Each grant free resource occupies the entire slot in the time domain, or 1 or more consecutive symbols in the slot (also referred to as a mini-slot). As shown in fig. 3, taking the third mini-slot in the slot as an example, in this time domain range, there are three grant free UEs, each UE is configured with two grant free resources of frequency division multiplexing, and the number of RBs of the grant free resources corresponding to the same UE is the same; the number of RBs corresponding to grant free resources of different UEs may be the same or different. The number of RBs depends on the size of the packet transmitted in the grant free uplink and the coding modulation scheme used.
In fig. 3, two grant free resources corresponding to the same UE are respectively defined as a main grant free resource and an auxiliary grant free resource, where the priority of the main grant free resource is higher than that of the auxiliary grant free resource. For example, the primary grant free resource of UE1 corresponds to zone 1, the secondary grant free resource corresponds to zone 2, and UE1 preferentially occupies zone 1.
When multiple auxiliary grant free resources are configured for the same UE, priorities can be selected for the multiple auxiliary grant free resources, and a grant free UE always selects the grant free resource which is not occupied by grant base and is configured for the grant free UE and has the highest priority for selection. Or, not configuring and selecting priorities for the plurality of secondary grant free resources, and when the primary grant free resources are occupied, the grant free UE randomly selects transmission resources from the unoccupied secondary grant free resources.
The second method comprises the following steps:
configuring a main grant free resource and a shared grant free resource for each grant free UE, wherein the shared grant free resource can be a resource set containing grant free resources of one or more UEs; alternatively, the shared grant free resource may be a whole upstream bandwidth part (BWP).
Specifically, as shown in fig. 4, within a time domain range of a certain grant free resource, there are three grant free UEs, and each UE is configured with a primary grant free resource, that is, the primary grant free resources of UE1, UE2, and UE3 are respectively region 1, region 2, and region 3 in the figure.
The shared grant free resource of a certain UE may be the primary grant resource of other UEs, i.e., for UE1, the shared grant free resource may be region 2, region 3. For UE2, the shared grant free resources may be zone 1 and zone 3. For UE3, the shared grant free resources may be zone 1 and zone 2.
Alternatively, the shared grant free resources may be a set of primary grant resources for all UEs, i.e., for UEs 1,2,3, the shared grant free resources are all region 1, region 2, and region 3.
Alternatively, the shared grant free resource may be the entire uplink BWP, i.e., for UE1, UE2 and UE3, the shared grant free resource is the entire BWP range.
In addition to the above preferred allocation of the shared grant free resources, any part of RBs in the uplink BWP may be allocated as shared grant free resources for the UE.
The third method comprises the following steps:
configuring a shared grant free resource for the grant free UE, where the shared grant free resource may be a part of an uplink bandwidth part (BWP) or the entire uplink BWP.
Specifically, as shown in fig. 5, the shared grant free resource may be shared by a plurality of UEs, and each UE is configured with the size of the grant free resource, that is, the number of RBs required for transmitting the grant free service, and the subsequent grant free UE may select the required number of RBs in the shared grant free resource according to the situation that the shared grant free resource is occupied by the grant base transmission. The specific resource selection manner will be described in detail in example 3 later.
Different UEs may also be configured with different shared grant free resources, as shown in fig. 6, the shared grant free resources 1,2, and 3 are the shared grant free resources of UEs 1,2, and 3, respectively, and each UE is also configured with the size of the grant free resource, i.e., the number of RBs required for transmitting the grant free service, respectively, and a subsequent grant free UE may select the required number of RBs in each shared grant free resource according to the situation that each shared grant free resource is occupied by grant base transmission. The specific resource selection manner will be described in detail in example 3 later.
Example 2
In this embodiment, a configuration method of the second resource set is described. The second Resource set is a Resource that is indicated to have been allocated to grant based service in a Reference Uplink Resource (RUR) region, where the RUR has a different size, specifically, includes one or more symbols in a time domain, and includes a whole Uplink BWP (several RBs) in a frequency domain; the manner of indicating the second resource set by using the second resource indication information includes:
the first method is as follows:
and fixing the bit number of the second resource indication information, and determining the frequency domain indication granularity according to the time domain symbol number occupied by the RUR. In particular, the method comprises the following steps of,
N DCI_bit number of bits, N, of the second resource indication information RUR_symbol The number of RUR symbols under case 1, the entire upstream BWP is divided into
Figure BDA0001943259950000091
Personal area。
The number of RBs in the last subband may also be different from the other subbands, specifically, for example, if the uplink BWP with RB number m is divided into n subbands, the number of RBs in the first n-1 subbands is:
Figure BDA0001943259950000101
the number of RBs of the last subband is:
Figure BDA0001943259950000102
a plurality of; or the RB number of the first n-1 sub-bands is as follows:
Figure BDA0001943259950000103
the number of RBs of the last subband is:
Figure BDA0001943259950000104
and (4) respectively.
Specifically, as shown in fig. 7 (a), under the overhead of the 14-bit second resource indication information, N is RUR_symbol =2, the number of subbands is 7, and assuming BWP contains m =100 RBs, the number of RBs contained in the first 6 subbands is:
Figure BDA0001943259950000105
and the number of RBs of the last subband is as follows:
Figure BDA0001943259950000106
a plurality of;
or, the number of RBs of the first 6 subbands is:
Figure BDA0001943259950000107
the number of RBs of the last subband is:
Figure BDA0001943259950000108
and (4) respectively.
Dividing RURs into N in the manner described above DCI_bit And each bit in the second resource indication information indicates the occupied condition of one sub-resource block. For example, the sub-resource blocks are arranged according to the sequence of 'frequency domain first and time domain later', and the second order isThe information bits from the lower bit to the higher bit in the two resource indication information are indicated in sequence.
FIG. 7 (b) shows the configuration of 4 symbol RURs, N, with overhead of 14bit second resource indicator RUR_symbol =4, then the number of subbands is
Figure BDA0001943259950000109
Assuming BWP contains m =100 RBs, the first 2 subbands contain the number of RBs:
Figure BDA00019432599500001010
and the number of RBs of the last subband is as follows:
Figure BDA00019432599500001011
a plurality of;
or, the number of RBs of the first 2 subbands is:
Figure BDA00019432599500001012
the number of RBs of the last subband is:
Figure BDA00019432599500001013
and (4) respectively.
In the case shown in fig. 7 (b), the RUR is divided into 12 blocks, and 12 bits can complete the intended indication, and the remaining 2 bits can be zero-padding. For example, the RUR is divided into 12 sub-resource blocks according to the above manner, and each bit of the lower 12 bits in the second resource indication information indicates an occupied condition of one sub-resource block. For example, the sub-resource blocks are arranged according to the sequence of 'frequency domain first and time domain later', and are sequentially indicated by information bits from low bits to high bits in the second resource indication information, and the high 2 bits are used for zero padding.
The second method comprises the following steps:
and fixing the number of sub-bands divided in the frequency domain, wherein the indication overhead of the second resource indication information is related to the number of symbols in the RUR. In particular, the method comprises the following steps of,
and if the number of the fixed configuration subbands is p, the time domain indication granularity is a symbol, or a mini-slot, and the overhead of the second resource indication information is p × q. Wherein q is the number of symbols in the RUR or the number of mini-slots in the RUR. In the two-symbol RUR configuration shown in fig. 8, the overhead of the second resource indicator is 7 × 2=14.
The method of partitioning the upstream BWP into a specified number of sub-bands is the same as the first way. The RUR is divided into 14 sub-resource blocks according to the above-mentioned manner, and each bit in the second resource indication information indicates an occupied condition of one sub-resource block. For example, the sub-resource blocks are arranged in the order of frequency domain first and time domain second, and are sequentially indicated by information bits from lower bits to higher bits in the second resource indication information.
Example 3
In this embodiment, a method for selecting resources by grant free UE according to a specific order is described. The UE may select resources in the following manner
The first method is as follows:
under the first resource set configuration shown in fig. 3, when a grant free service arrives, a grant free UE selects resources for transmitting the grant free service in the following order:
if the main grant free resource belonging to the grant free UE does not exist intersection with the second resource set (namely the main grant free resource is not allocated to grant based service transmission), the grant free UE selects the own main grant free resource;
if the main grant free resource belonging to the grant free UE has an intersection with the second resource set (namely, part of RBs or all RBs of the main grant free resource are allocated to grant based service transmission), the grant free UE selects an auxiliary grant free resource which has no intersection with the second resource set;
if the intersection exists between the main grant free resource and all the auxiliary grant free resources belonging to the grant free UE and the second resource set, the following two cases can be further distinguished:
if the number of resources (namely the number of idle RBs) outside the second resource set in the BWP is more than or equal to the number of RBs required by the grant free transmission, randomly selecting the required number of RBs in the idle RBs; or, calculating and determining the occupied RB according to the UE ID and a specific rule, which will be described in embodiment 4 later;
if the number of resources (i.e., the number of idle RBs) outside the second resource set in the BWP is smaller than the number of RBs required for grant free transmission, the grant free transmission occupies all idle RBs, and randomly selects the remaining number of RBs in the range of all non-idle RBs, or calculates and determines the occupied RBs according to the UE ID and a specific rule, which will be described in embodiment 4. In addition, at this time, the grant free and grant based transmissions will overlap, and the grant free can perform power boosting transmission on the overlapping resources; or the grant free performs power-up transmission on all occupied resources.
The second method comprises the following steps:
under the first resource set configuration shown in fig. 4, when a grant free service arrives, a grant free UE selects resources for transmitting the grant free service in the following order:
if the main grant free resource belonging to the grant free UE does not exist an intersection with the second resource set (i.e. the main grant free resource is not allocated to grant based traffic transmission), the grant free UE selects its own main grant free resource;
if there is an intersection between the main grant free resource belonging to the grant free UE and the second resource set (i.e. part of RBs or all RBs of the main grant free resource are allocated to grant based traffic transmission), the following two cases can be further divided into:
if the number of resources without intersection with the second resource set (namely, the free RB in the shared grant free resource) in the shared grant free resource is more than or equal to the number of the RB required for the grant free transmission, randomly selecting the number of the RB required for the grant free transmission in the free RB in the shared grant free resource; or calculating and determining the occupied RB according to the UE ID and a specific rule, which is specifically described in embodiment 4;
if the number of resources (i.e., the number of free RBs) outside the second resource set in the BWP is less than the number of RBs required for the grant free transmission, the grant free transmission occupies free RBs in all the shared grant free resources, and randomly selects the remaining number of RBs within the non-free RB range in all the shared grant free resources, or determines the occupied RBs according to the UE ID and a specific rule, which is specifically described in embodiment 4. In addition, at this time, the grant free and grant based transmissions will overlap, and the grant free can perform power boosting transmission on the overlapping resources; or, the grant free performs power-up transmission on all occupied resources.
The third method comprises the following steps:
in the first resource set allocation method described in embodiment 1, when a grant free service arrives, a grant free UE may select a resource for transmitting the grant free service as follows:
if the number of resources without intersection with the second resource set (namely free RBs in the shared grant free resources) in the shared grant free resources is more than or equal to the number of RBs required for transmitting the grant free, randomly selecting the number of RBs required for transmitting the grant free from the free RBs in the shared grant free resources; or calculating and determining the occupied RB according to the UE ID and a specific rule, which will be specifically described in embodiment 4;
if the number of resources (i.e., the number of free RBs) outside the second resource set in the BWP is less than the number of RBs required for the grant free transmission, the grant free transmission occupies free RBs in all shared grant free resources, and randomly selects the remaining number of RBs in the non-free RB range in all shared grant free resources, or determines the occupied RBs according to the UE ID and a specific rule, which will be described in detail in embodiment 4. In addition, at this time, the grant free and grant based transmissions will overlap, and the grant free can perform power boosting transmission on the overlapping resources. Or the grant free performs power boosting transmission on all occupied resources.
Example 4
In this embodiment, a method for selecting a grant free resource by a grant free UE when the number of idle RBs is equal to or greater than the number of RBs required for transmitting the grant free service is described.
In embodiment 3, when the primary grant free resource and the secondary grant free resource (if configured) of a grant free UE are occupied, the grant free UE selects the required RB from other free resources for the grant free transmission. As shown in fig. 9, by taking the first resource set configuration example of the mode 1 in the embodiment 1, for the UE3, both the primary grant free resource and the secondary grant free resource are occupied by grant based service (specifically, the primary grant free resource is scheduled for eMBB service transmission), and the remaining idle resources include the region 1 and the region 3. In the following, how grant free UE3 selects the required RB from the idle RBs for grant free traffic transmission is described in detail.
It is assumed here that the number of free RBs is NRB and is numbered sequentially in a certain order (e.g., from low to high in frequency) as 0,1 RB-1 The number of RBs required for grant free transmission is M.
The method I comprises the following steps:
m RBs that are "contiguous" are selected according to the UE ID. The number of the selected RB is calculated using the following formula:
{(n RNTI modN RB )+m}modN RB
wherein n is RNTI As identity of the UE, e.g. C-RNTI, n RNTI E {0, 1., 65535}, M =0, \ 8230;, M-1, and the calculated set of RB numbers is the resource selected by the UE.
In particular, assume that n RNTI =35159, nrb =30, m =10, { (35159 mod 30) + m } mod30, \ 8230for m =0, 9, the calculation yields a set of RB numbers: 29,0,1,2,3,4,5,6,7,8.
As can be seen from the above example, the calculated set of RBs is not necessarily contiguous in physical frequency location. For example, when the RB number reaches the highest RB, it will cycle to the lowest RB; further, the RBs with consecutive numbers may cross the boundary of the region (e.g., the boundary between region 1 and region 3), and in this case, the set of RBs is also not consecutive in physical frequency position.
The second method comprises the following steps:
m RBs which are 'continuous' are selected according to the UE ID and the slot, and the number of the selected RB is calculated by the following formula:
{(Y k modN RB )+m}modN RB
wherein, Y k =(A·Y k-1 )modD,Y -1 =n RNTI ≠0,A p =39827,D=65537,n RNTI Being an identity of the UE, e.g. C-RNTI, n RNTI E {0, 1., 65535}, k being the slot index, M =0, \ 8230;, M-1.
In particular, assume that n RNTI =35159, NRB =30, M =10, k =1, then
Y 0 =(A·Y -1 )modD=(39827*35159)mod65537=13951,
Y 1 =(A·Y 0 )modD=(39827*13951)mod65537=3791
For m =0, \8230, 9, a set of RB numbers calculated by { (3791 mod 30) + m } mod30 is: 11,12,13,14,15,16,17,18,19,20.
As can be seen from the above example, the calculated set of RBs is not necessarily contiguous in physical frequency location. For example, if the RB numbers cross the boundary between region 1 and region 3, the physical frequency positions of the group of RBs are not consecutive.
The third method comprises the following steps:
m RBs of "discrete number" are selected according to the UE ID, and the number of the selected RB is calculated using the following formula:
Figure BDA0001943259950000151
wherein n is RNTI Being an identity of the UE, e.g. C-RNTI, n RNTI E {0, 1., 65535}, M =0, \8230, M-1, and the calculated set of RB numbers is the resource selected by the UE.
In particular, assume that n RNTI =35159, nrb =30, m =10, then
Figure BDA0001943259950000152
For m =0, \ 8230;, 9, a set of RB numbers is calculated as: 29,2,5,8,11,14,17,20,23,26.
The method is as follows:
selecting discrete M RBs according to the UE ID and the slot, and calculating the number of the selected RBs by using the following formula:
Figure BDA0001943259950000153
wherein, Y k =(A·Y k-1 )modD,Y -1 =n RNTI ≠0,A p =39827,D=65537,n RNTI Being an identity of the UE, e.g. C-RNTI, n RNTI E {0, 1., 65535}, k is slot index, M =0, \8230, M-1.
In particular, assume that n RNTI =35159, nrb =30, m =10, k =1. Then
Y 0 =(A·Y -1 )modD=(39827*35159)mod65537=13951,
Y 1 =(A·Y 0 )modD=(39827*13951)mod65537=3791
For m =0, \8230;, 9, by
Figure BDA0001943259950000161
Calculating to obtain a group of RB numbers as: 11,14,17,20,23,26,29,2,5,8.
The fifth mode is as follows:
the Grant free UE may also select the required number of RBs in a random manner within the free RB range.
Example 5
In this embodiment, a method for selecting a grant free resource by a grant free UE when the number of idle RBs is less than the number of RBs required for transmitting the grant free service is described.
In embodiment 3, when the primary and secondary grant free resources (if configured) of a grant free UE are all occupied and the number of idle RBs is less than the number of RBs required for transmitting the grant free service, the grant free UE will occupy all idle RBs, and select the remaining number of RBs from the 'non-idle RBs' (which may be resources in the second resource set or overlapping resources of the shared grant free resource and the second resource set).
For example, the number of RBs required for transmitting the grant free service is X, the number of idle RBs is Y, Y<X, then M = X-Y RBs need to be selected within non-idle RBs. Suppose the non-idle RB is N RB
In embodiment 4, the method of selecting M RBs from NRB RBs described in the manners one to five is also applicable to this embodiment.
The selected M RBs and the original idle Y RBs together form X RBs required for transmitting the grant free service.
Example 6
In this embodiment, a method for boosting power of grant free transmission when the grant free resource selected by the grant free UE overlaps with the 'second resource set' (i.e. a part of RBs or all RBs of the grant free resource are allocated to grant based traffic transmission) is described.
In the case described in embodiment 5, Y RBs out of the X RBs to which the grant free service is transmitted have been allocated to the grant based service, and at this time, the grant free service and the grant based service will be transmitted simultaneously on the Y RBs.
One or more overlap resource ratio thresholds may be predefined, wherein the overlap resource ratio is defined as: the ratio of the resources already allocated to grant based services to the total resources of grant free services. For example, the thresholds include: the mapping relationship between the interval of the actual overlapping resource proportion x and the power boost amount is predefined as shown in the following table 1:
TABLE 1
Actual overlapping resource ratio x Amount of power boost
x≤30% Without increasing power
30%<x≤50% 3dB power boost
50%<x≤80% 6dB of boost power
x>80% Boost power of 9dB
And the Grant free UE judges which interval falls in according to the proportion of the actual overlapped resources, and promotes the corresponding power quantity. For example, when grant free total resource =10RB and overlap resource =4RB, the overlap resource ratio is 40%, and the transmission for grant free will be boosted by 3dB power.
The predefined thresholds and the amount of power boosted in each interval are specified in the protocol or configured by the gNB and signaled to the UE. The above values are only examples and any other predefined values are possible.
In addition, boosting power includes the following ways:
1) Increasing power of all Resource Elements (REs) occupied by transmission of the grant free;
2) Boosting power only on overlapping REs, i.e., on REs whose grant free transmission resources overlap with the second set of resources;
3) All REs of the symbol where the overlapping resources are located boost power.
In the above method embodiments of the present disclosure, the UE may select grant free transmission resources in the resource selection order through reception of the first resource set and the second resource set. According to the scheme provided by the disclosure, the multiplexing of grant free uplink transmission and grant based uplink transmission can be effectively realized, the probability of resource conflict between grant free uplink transmission is reduced, and the resource utilization efficiency is improved.
