Background

In future communication systems, an Unlicensed Band (Unlicensed Band) may be used as a supplement to a Licensed Band (Licensed Band) to help an operator to expand the capacity of services. Since the unlicensed frequency band is shared by multiple Radio Access Technologies (RATs), such as wireless local area network Wi-Fi, radar, LTE-based Licensed-Assisted Access to unlicensed spectrum (LTE-LAA), and the like, in some countries or regions, the unlicensed frequency band must meet regulatory requirements to ensure that all devices can fairly share the resource when in use, and before transmitting information, the terminal or the network device needs to perform Channel idle assessment (CCA)/extended Channel idle assessment (eCCA) to listen to a Channel, that is, perform Energy Detection (ED), and when Energy is lower than a certain threshold, the Channel is determined to be empty, and the terminal may start transmission. Such as Listen Before Talk (LBT), Maximum Channel Occupancy Time (MCOT), etc.

Therefore, how to determine the resources of the physical uplink shared channel PUSCH for unlicensed spectrum transmission becomes an urgent problem to be solved.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, a method for allocating uplink resources according to an embodiment of the present invention includes:

step 101, receiving uplink authorization information.

Here, the uplink grant information carries target indication information for indicating frequency domain resources allocated in active UL BWP for PUSCH transmission. In this step, the user equipment performs subsequent steps based on the uplink authorization information by receiving the uplink authorization information.

And step 102, determining target frequency domain resources for transmitting a Physical Uplink Shared Channel (PUSCH) according to the target indication information in the uplink authorization information.

In this step, after receiving the uplink grant information in step 101, the target frequency domain resource for transmitting the PUSCH can be determined by further following the target indication information in the uplink grant information.

Thus, through the

above steps

101 and 102, the method of the embodiment of the present invention is applied to the user equipment, and after receiving the uplink grant information, the user equipment can determine the target frequency domain resource for transmitting the PUSCH by using the target indication information for indicating the frequency domain resource for PUSCH transmission allocated in the active UL BWP in the uplink grant information, so as to ensure the realization of transmission by using the target frequency domain resource.

Optionally, the uplink grant information is uplink grant information in a random access response.

Thus, the uplink grant information UL grant is specifically an uplink grant information RAR UL grant in the random access response. The UE detects Downlink control information DCI 1_0 scrambled by a random access radio network temporary identifier RA-RNTI and a corresponding Physical Downlink Shared Channel (PDSCH), and transmits a Transport Block (TB) transmitted by the PDSCH to a higher layer, and the higher layer parses the transport block. If the higher layer identifies a Random Access Preamble Identifier (RAPID) associated with Physical Random Access Channel (PRACH) transmission sent by the UE in a Random Access Response (RAR) message in the transport block, the higher layer indicates the UL grant to the Physical layer, and the grant is called an RAR UL grant in the Physical layer. That is, the uplink grant in the present invention is not necessarily directly transmitted from the base station to the physical layer of the user equipment, but may be indirectly transmitted, for example, the uplink grant is passed to the physical layer after the information received from the base station is analyzed by the higher layer of the user equipment. The user equipment acquires the target indication information through the RAR UL grant, and then determines the frequency domain resources for PUSCH transmission allocated in active UL BWP. Wherein, the target indication information is information of a frequency domain resource allocation domain in the RAR UL grant.

In this embodiment, optionally, the target indication information includes a first indication; the first indication is used for indicating interlace allocation of the PUSCH transmission, and the first indication occupies X bits; wherein the content of the first and second substances,

the value of X is determined by active UL BWP or subcarrier spacing SCS of initial UL BWP

Thus, after receiving the uplink grant information such as the RAR UL grant in step 101, X bits of information are truncated as a first indication, and the interlace allocation for PUSCH transmission is determined by the first indication, for example, X bits of the least significant bits of the frequency domain resource allocation field of the RAR UL grant are truncated.

Wherein, the value of X is determined by active UL BWP or subcarrier spacing SCS of initial UL BWP. Preferably, SCS is 15kHz, then X ═ 6; SCS is 30kHz, X is 5. Moreover, to explicitly indicate interlace allocation, the first indication is specifically implemented as follows:

when X is 6, the 6-bit information indicates Resource Indication Value (RIV) for indicating the allocated resources of the interlace, and when the RIV value satisfies that RIV is more than or equal to 0 and less than or equal to M (M +1)/2, the starting interlace index of the continuously allocated interlaces and the number of the allocated interlaces are indicated; a predefined interlace allocation is indicated when the RIV value satisfies RIV ≧ M (M +1)/2, where M denotes the number of interlaces within the BWP, optionally M ═ 10. When X is 5, the 5-bit information is a bitmap indicating allocation of interlaces, and each bit from a Most Significant Bit (MSB) to a Least Significant Bit (LSB) corresponds to interlaces 0,1, 2, 3, and 4, respectively, then 0 in the 5-bit information indicates that the corresponding interlaces are not allocated, and 1 indicates allocation.

Of course, X may also be a preset value, and based on the preset value, the first indication is intercepted and obtained from the uplink authorization information.

Optionally, the target indication information further includes a second indication, where the second indication is used to indicate resource block set (RB set) allocation of the PUSCH transmission, and the second indication occupies Y bits; wherein the content of the first and second substances,

and Y is a preset value, or the value of Y is determined by the number of RB sets configured by active UL BWP.

In this way, after receiving uplink grant information such as RAR UL grant via step 101, Y-bit information may be truncated as a second indication, and RB set allocation for PUSCH transmission may be determined by the second indication.

Here, the second indication is information occupying Y bits in the uplink grant information, where a value of Y may be a preset value, for example, Y is 4; the number of RB sets configured based on active UL BWP may also be

For example by means of a formula

Thus, the compound was obtained.

Of course, in the uplink grant information, the interception start positions of the first indication and the second indication may be preset. Specifically, in the uplink authorization information, the first indication is intercepted from LSB to MSB, and then the second indication is intercepted; or intercepting the first indication from the MSB to the LSB and then intercepting the second indication; or intercepting the second indication from the LSB to the MSB, and then intercepting the first indication; alternatively, the second indication is intercepted first from the MSB to the LSB, and then the first indication is intercepted.

Assuming that Y is configured to be 4 in advance, the truncation start positions of the first and second indications are obtained by sequentially truncating the first and second indications from the LSB in the frequency domain resource allocation field of the RAR UL grant. Therefore, in case of active UL BWP or SCS of initial UL BWP is 30kHz, the first indication "01100" containing 5 bits of information and the second indication "0001" containing 4 bits of information can be intercepted by 12 bits of information 000000101100 in the frequency domain resource allocation domain of RAR UL grant. Thus, from the first indication "01100", it is known that two interlaces with interlace index 1 and 2 are allocated, i.e., interlace1 and interlace 2, for PUSCH transmission; RB set for PUSCH transmission is known by the second indication "0001". For example, the second indication represents an RIV value (RIV) for RB set allocation_RBset) When is coming into contact with

The RIV value corresponds to the starting RB set (RBset)_START) And the number of consecutive RB sets L_RBset(L_RBsetNot less than 1). The RIV value is defined as follows:

if it is

Then

If not, then,

in addition, in this embodiment, optionally, the method further includes:

determining RB set for the PUSCH transmission.

In this way, the interlace used for PUSCH transmission is determined by the target indication information in the uplink grant information, that is, when the target indication information is the first indication, the RB set used for PUSCH transmission needs to be determined. At this time, the determined RB set for PUSCH transmission may be predefined or indicated in the uplink grant information.

Optionally, the determining the set of RBs for the PUSCH transmission includes:

determining RB set contained in the initial UL BWP to be RB set used for the PUSCH transmission in the active UL BWP under the condition that the active UL BWP and the initial UL BWP have the same SCS and the same cyclic prefix CP length and the RB contained in the active UL BWP configuration or equal to all the RB configured in the initial UL BWP; alternatively, the first and second electrodes may be,

determining the m-th RB to m + L-th RB configured by the active UL BWP as an RB set for the PUSCH transmission under the condition that the active UL BWP and the initial UL BWP have different SCS, or the active UL BWP and the initial UL BWP have different CP lengths, or the RB configured by the active UL BWP does not contain and is not equal to all the RBs configured by the initial UL BWP, wherein m is a positive integer, and L is equal to the number of the RBs configured by the initial UL BWP; alternatively, the first and second electrodes may be,

taking a first preset RB set in active UL BWP as an RB set for PUSCH transmission under the condition that the active UL BWP and the initial UL BWP have different SCS, or the active UL BWP and the initial UL BWP have different CP lengths, or the RB configured by the active UL BWP does not contain and is not equal to all the RBs configured by the initial UL BWP; alternatively, the first and second electrodes may be,

and when the active UL BWP and the initial UL BWP have different SCSs, or the active UL BWP and the initial UL BWP have different CP lengths, or the RBs configured by the active UL BWP do not contain and are not equal to all the RBs configured by the initial UL BWP, determining the RB set for the PUSCH transmission according to the information of Q bits in the uplink grant information.

Here, for a specific scenario, the applicable RB set for transmitting PUSCH is further determined, and in conjunction with the first indication, the determination of the frequency domain resources for transmitting PUSCH is completed. The information of the Q bit is similar to a second indication, the value of Q can be determined by a preset value, and the number of RB sets configured based on active UL BWP can also be determined

For example by the formula

And (4) obtaining.

For example, in a scenario one, it is assumed that SCS of active UL BWP is 15kHz (active UL BWP includes 10 interlaces), the number of RBs included is 104, two RB sets are configured in the radio resource control RRC, SCS of initial UL BWP is 30kHz (initial UL BWP includes 5 interlaces), and the number of RBs included is 51. It can be seen that the SCS of the Active UL BWP is different from the SCS of the initial UL BWP.

Therefore, in the first aspect, the 1 st RB to the 51 st RB, i.e., RB 0, …, 50, of the active UL BWP configuration may be determined as the RB set for PUSCH transmission. And, in case that X is determined to be 5 in SCS of initial UL BWP, the two interlaces with interlaces index 1 and 2, i.e., interlace1 and interlace 2, can be determined by truncating the first indication "01100" of 5-bit LSB from 12-bit "000000001100" in the frequency domain resource allocation domain of RAR UL grant, if 5-bit bitmap corresponds to interlaces 0,1, …,4 from MSB to LSB, respectively. In this way, the UE identifies the physical resource blocks PRB corresponding to interlace1 and interlace 2 in RB 0, …, 50 in active UL BWP.

In the second aspect, it is also possible to directly determine some RB set or sets in active UL BWP, for example, the first RB set (first preset RB set) as the RB set for PUSCH transmission. And, when two interlaces with interlace index of 1 and 2 are determined to be allocated in the same way as the first aspect, the UE determines the PRB corresponding to interlace1, 2 within the first RB set in active UL BWP.

In a third aspect, 12 bits from the frequency domain resource allocation field in the RAR UL grant may also be usedTruncated 2-bit (Q ═ 2) information "01" in "000000101100" is used to indicate the allocated RB set. Here, 2-bit information "01" indicates the allocated consecutive RB sets in the form of an RIV, and 01 means that the RIV value is 1, and the allocated starting RB set, RBset can be determined according to the manner in which the RIV is defined_START1, number of RB sets allocated consecutively, L_RBset1, i.e. a second RB set, i.e. RB set, is allocated₁. And, when two interlaces with interlace index of 1 and 2 are determined to be allocated in the same manner as the first aspect, the UE RB set in active UL BWP₁And internally determining the PRB corresponding to the interlace1, 2.

Of course, in the above implementation, if X is determined to be 6 by SCS of active UL BWP, 6 bits need to be truncated from 12 bits in the frequency domain resource allocation domain of RAR UL grant to determine interlace allocation, which is not described herein again.

For example, in scenario two, it is assumed that SCS of active UL BWP is 30kHz (active UL BWP includes 5 interlaces), CP length is NCP, RRC has two RB sets configured, SCS of initial UL BWP is 30kHz (initial UL BWP includes 5 interlaces), CP length is NCP, and the number of RBs included is 51.

If the active UL BWP includes all RBs of the initial UL BWP, the active UL BWP and the initial UL BWP have the same SCS and the same CP length, and the RBs of the active UL BWP configuration include or equal to all RBs of the initial UL BWP configuration. Therefore, the frequency domain resource allocation of PUSCH is determined using the initial UL BWP, and the first indication "01100" of 5-bit LSB is truncated from 12-bit "000000001100" in the frequency domain resource allocation domain in the RAR UL grant, indicating that interlace1 and interlace 2 are allocated. In this way, the UE determines PRBs corresponding to interlace1 and interlace 2 in the initial UL BWP.

And if the active UL BWP does not contain all RBs of the initial UL BWP, determining the target frequency domain resource in the same scene one mode.

In addition, in this embodiment, another implementation is as follows, and step 102 further includes:

determining candidate interlaces;

according to the first indication, determining interlaces for the PUSCH transmission in the candidate interlaces.

Thus, after preferentially determining the candidate interlace, the interlace for transmitting the PUSCH is further determined in combination with the first indication.

Optionally, the determining the candidate interlace includes:

when active UL BWP and initial UL BWP have the same SCS and the same CP length, and RBs configured by the active UL BWP contain or are equal to all RBs configured by the initial UL BWP, determining interlaces contained by the initial UL BWP as candidate interlaces;

and under the condition that the active UL BWP and the initial UL BWP have different SCS, or the active UL BWP and the initial UL BWP have different CP lengths, or the RBs configured by the active UL BWP do not contain and are not equal to all the RBs configured by the initial UL BWP, taking the nth interlace to the n + K interlaces configured by the active UL BWP as candidate interlaces, wherein n is a positive integer, and K is equal to the number of interlaces contained by the initial UL BWP.

Here, after an applicable candidate interlace is further determined for a specific scenario, the determination of the frequency domain resource for transmitting the PUSCH is completed in combination with the first indication.

Corresponding to the determination that the candidate interlace is needed, in this embodiment, optionally, the method further includes:

and taking a second preset RB set in active UL BWP as the RB set for the PUSCH transmission.

As such, the second preset RB set in active UL BWP may be used for PUSCH transmission based on the preset. Of course, the RB set for PUSCH transmission can also be determined by the second indication occupying Y bits in the uplink grant information.

For example, in scenario three, assuming that the SCS of active UL BWP is 15kHz (active UL BWP includes 10 interlaces), the RRC has two RB sets configured, and the SCS of initial UL BWP is 30kHz (initial UL BWP includes 5 interlaces), and the number of RBs included is 51. It can be seen that the SCS of the Active UL BWP is different from the SCS of the initial UL BWP.

Therefore, 5 interlaces, i.e. interlaces 0,1, …,4, can be truncated from the first interlace of the active UL BWP. And, in case that X is determined to be 5 in SCS of initial UL BWP, the first indication "01100" of 5-bit LSB can be truncated from 12-bit "000000001100" in the frequency domain resource allocation domain of RAR UL grant, where each bit from MSB to LSB corresponds to interlace 0,1, …,4, respectively, and 0 means the interlace is not allocated and 1 means allocation. The first indication "01100" indicates that two interlaces with interlace indexes 1 and 2 are allocated. And determining the RB set for transmitting the PUSCH: on the one hand certain/certain of the active UL BWP may be used, e.g. the first RB set (second predetermined RB set), i.e. RB set₀(ii) a On the other hand, after the first indication is truncated, 2 bits (Y ═ 2) information "00" is truncated from the remaining 7 bits of information "0000001" of 12 bits, or 2 bits of LSB are truncated first to indicate RB set allocation, and then 5 bits of LSB are truncated from the remaining 10 bits to indicate interlace allocation. Finally, the allocated interlace, such as the PRBs corresponding to interlace1 and interlace 2, is determined within the allocated RB set, such as the first RB set.

In a fourth scenario, it is assumed that SCS of active UL BWP is 30kHz (active UL BWP includes 5 interlaces), CP length is NCP, RRC has two RB sets, SCS of initial UL BWP is 30kHz (initial UL BWP includes 5 interlaces), CP length is NCP, and the number of RBs included is 51. And, active UL BWP does not contain all RBs of the initial UL BWP. Then it implements the same scenario three.

To sum up, after receiving the uplink grant information, the method according to the embodiment of the present invention can determine the target frequency domain resource for transmitting the PUSCH by using the target indication information for indicating the frequency domain resource allocated in the active UL BWP for PUSCH transmission in the uplink grant information, so as to ensure the implementation of transmission by using the target frequency domain resource.

As shown in fig. 2, an embodiment of the present invention further provides an uplink resource allocation method, including:

step 201, sending uplink grant information, where the uplink grant information includes target indication information, and the target indication information is used to indicate frequency domain resources allocated in active UL BWP for PUSCH transmission.

In this way, the uplink grant information is sent, so that after receiving the uplink grant information, the user equipment can determine the target frequency domain resource for transmitting the PUSCH from the target indication information for indicating the frequency domain resource for PUSCH transmission allocated in active UL BWP in the uplink grant information, thereby ensuring the implementation of transmission using the target frequency domain resource.

Optionally, the target indication information comprises a first indication; the first indication is used for indicating interlace allocation of the PUSCH transmission, and the first indication occupies X bits; wherein the content of the first and second substances,

the value of X is determined by the subcarrier spacing SCS of active UL BWP or initial UL BWP.

Preferably, SCS is 15kHz, then X ═ 6; SCS is 30kHz, X is 5. Moreover, to explicitly indicate interlace allocation, the first indication is specifically implemented as follows:

when X is 6, the 6-bit information is a resource indication bit RIV for indicating interlace allocation, and when the RIV value satisfies that RIV is more than or equal to 0 and less than or equal to M (M +1)/2, continuously allocated interlaces are indicated; a predefined interlace allocation is indicated when the RIV value satisfies RIV ≧ M (M +1)/2, where M represents the number of interlaces within the BWP. When X is 5, the 5-bit information is a bitmap indicating allocation of interlace, each bit from the MSB of the most significant bit to the LSB of the least significant bit corresponds to interlace 0,1, 2, 3, 4, respectively, then 0 in the 5-bit information indicates that the interlace is not allocated, and 1 indicates allocation.

y is a preset value, or the value of Y is determined by the number of RB sets configured by active UL BWP.

In particular by means of formulae

Thus, the compound was obtained.

Assuming that Y is configured to be 4 in advance, the truncation start positions of the first and second indications are obtained by sequentially truncating the first and second indications from the LSB in the frequency domain resource allocation field of the RAR UL grant. Therefore, in case of active UL BWP or SCS of initial UL BWP is 30kHz, the first indication "01100" containing 5 bits of information and the second indication "0001" containing 4 bits of information can be intercepted by 12 bits of information 000000101100 in the frequency domain resource allocation domain of RAR UL grant. Thus, from the first indication "01100", two interlaces, i.e., interlace1 and interlace 2, to which interlace indexes 1 and 2 are allocated, are known for PUSCH transmission; RB set for PUSCH transmission is known by the second indication "0001".

As shown in fig. 3, an embodiment of the present invention further provides a user equipment, including:

a receiving module 310, configured to receive uplink grant information;

a first processing module 320, configured to determine, according to target indication information in the uplink grant information, a target frequency domain resource for transmitting a physical uplink shared channel PUSCH;

Optionally, the apparatus further comprises:

Optionally, the second processing module is further configured to:

Optionally, the first processing module includes:

the first processing submodule is used for determining candidate interlaces;

and the second processing submodule is used for determining the interlace used for the PUSCH transmission in the candidate interlaces according to the first indication.

Optionally, the first processing sub-module is further configured to:

Optionally, the method further comprises:

and the third processing module is used for taking a second preset RB set in active UL BWP as the RB set for PUSCH transmission.

After receiving the uplink grant information, the ue of this embodiment can determine a target frequency domain resource for PUSCH transmission by using target indication information for indicating the frequency domain resource allocated in active UL BWP for PUSCH transmission in the uplink grant information, so as to ensure that transmission is achieved by using the target frequency domain resource.

The user equipment can implement each process implemented by the user equipment in the embodiment of the method in fig. 1, and is not described herein again to avoid repetition.

As shown in fig. 4, an embodiment of the present invention further provides a network side device, including:

a sending module 401, configured to send uplink grant information, where the uplink grant information includes target indication information, and the target indication information is used to indicate frequency domain resources allocated in active UL BWP for PUSCH transmission.

The network side equipment sends the uplink authorization information, so that after the user equipment receives the uplink authorization information, the user equipment can determine the target frequency domain resource for transmitting the PUSCH according to the target indication information which is used for indicating the frequency domain resource for PUSCH transmission and allocated in active UL BWP in the uplink authorization information, and therefore the target frequency domain resource is used for ensuring the realization of transmission.
