Detailed Description
In the prior art, when a base station schedules a short-duration user terminal to multiplex uplink time-frequency resources of the long-duration user terminal, the long-duration user terminal cannot acquire the multiplexed uplink time-frequency resources.
In the embodiment of the invention, the base station sends the uplink multiplexing time-frequency resource indication to the long-duration user terminal. The long-duration user terminal monitors according to the monitoring period indicated by the uplink multiplexing time-frequency resource, and determines the uplink multiplexing time-frequency resource according to the uplink multiplexing time-frequency resource indication in one monitoring period, so that the long-duration user terminal can acquire a physical resource block for uplink multiplexing on a frequency domain corresponding to the uplink multiplexing time-frequency resource and an OFDM symbol for uplink multiplexing on a time domain.
In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below.
The embodiment of the invention provides a method for determining uplink multiplexing time-frequency resources, and the method is described in detail through specific steps with reference to fig. 1.
Step S101, receiving an uplink multiplexing time-frequency resource instruction issued by a base station.
In a specific implementation, the ue 1 may receive an uplink multiplexing time-frequency resource indication issued by the base station. The user terminal 1 may be a long-duration user terminal, that is, a user terminal with a long data transmission duration. In an embodiment of the present invention, the user terminal 1 is an eMMB user terminal.
The user terminal 2 is a short-duration user terminal, and in order to meet the low-delay requirement of the user terminal 2, the base station can schedule the user terminal 2 to multiplex the uplink time-frequency resource of the user terminal 1. When the base station determines that the user terminal 2 multiplexes the uplink time-frequency resource of the user terminal 1, the base station may issue an uplink multiplexing time-frequency resource indication to the user terminal 1. In an embodiment of the present invention, the user terminal 2 is a URLLC user terminal.
In a specific implementation, when the base station issues an uplink multiplexing time-frequency resource instruction to the user terminal 1, downlink control information (Downlink Control Information, DCI) may be used to issue the uplink multiplexing time-frequency resource instruction to the user terminal 1. The user terminal 1 receives an uplink multiplexing time-frequency resource indication sent by the base station by adopting DCI.
When the base station adopts DCI to issue uplink multiplexing time-frequency resource indication to the user terminal 1, the base station may issue uplink multiplexing time-frequency resource indication to the user terminal 1 according to a preset sending period, and the sending period of the base station may be equal to the monitoring period of the user terminal 1. The DCI adopted by the base station may be DCI corresponding to the 5G NR DCI format 2-1, and the DCI corresponding to the 5G NR DCI format 2-1 may be scrambled by a dedicated radio network temporary identifier (Radio Network Tempory Identity, RNTI).
When the base station transmits the uplink multiplexing time-frequency resource instruction to the user terminal 1, the base station may transmit the uplink multiplexing time-frequency resource instruction to the user terminal 1 via a physical downlink control channel (Physical Downlink Control Channel, PDCCH) or transmit the uplink multiplexing time-frequency resource instruction to the user terminal 1 via a group common physical downlink control channel (group common PDCCH).
Step S102, monitoring is carried out according to the monitoring period indicated by the uplink multiplexing time-frequency resource, and in one monitoring period, the uplink multiplexing time-frequency resource is determined according to the uplink multiplexing time-frequency resource indication.
In a specific implementation, the ue 1 may monitor the received uplink multiplexing time-frequency resource indication according to the monitoring period of the uplink multiplexing time-frequency resource indication. The ue 1 may determine the uplink multiplexing time-frequency resource according to the received uplink multiplexing time-frequency resource indication in a listening period.
In a specific implementation, the uplink multiplexing time-frequency resource may include a resource in a frequency domain and a resource in a time domain, where: the resources on the frequency domain included in the uplink multiplexing time-frequency resource may be: physical resource blocks for uplink multiplexing on the frequency domain; the resources in the time domain included in the uplink multiplexing time-frequency resource may be: the OFDM symbols that are uplink multiplexed in the time domain.
In a specific implementation, when determining the uplink multiplexing time-frequency resource according to the uplink multiplexing time-frequency resource indication, the user terminal 1 may divide the uplink multiplexing time-frequency resource indication into X groups according to the number of bits included in the uplink multiplexing time-frequency resource indication, where the value of X is related to the listening period of the uplink multiplexing time-frequency resource indication. And then, the user terminal 1 determines the uplink multiplexing time-frequency resource according to the value of the bit corresponding to each group in the X groups.
In the embodiment of the present invention, the ue 1 divides the uplink multiplexing time-frequency resource indication into X groups, where: the front mod (N, X) groups in X groups, each group comprising ceil (N/X) bits; a post X-mod (N, X) group of X groups, each group including floor (N/X) bits; n is the bit number contained in the uplink multiplexing time-frequency resource indication, mod (N, X) is the modulo of N to X, ceil (N/X) is the upward rounding of the value of N/X, floor (N/X) is the downward rounding of the value of N/X.
In a specific implementation, the value of X may relate to a listening period indicated by the uplink multiplexing time-frequency resource. In the embodiment of the invention, the value of X is as follows: the number of non-downlink OFDM symbols in a monitoring period indicated by an uplink multiplexing time-frequency resource.
For example, the listening period indicated by the uplink multiplexing time-frequency resource is 7 OFDM symbols, and the number of downlink OFDM symbols in the listening period indicated by one uplink multiplexing time-frequency resource is 2, then x=7-2=5.
When the value of X is the number of non-downlink OFDM symbols in the monitoring period indicated by the uplink multiplexing time-frequency resource, aiming at the ith group in the X groups, the ith group corresponds to the ith non-downlink OFDM symbols in the monitoring period indicated by the uplink multiplexing time-frequency resource one by one.
For example, in a listening period indicated by an uplink multiplexing time-frequency resource, the number of non-downlink OFDM symbols is 5. The uplink multiplexing time-frequency resource indication is divided into 5 groups: the 1 st group corresponds to the 1 st non-downlink OFDM symbol in the monitoring period indicated by the uplink multiplexing time-frequency resource, the 2 nd group corresponds to the 2 nd non-downlink OFDM symbol in the monitoring period indicated by the uplink multiplexing time-frequency resource, the 3 rd group corresponds to the 3 rd non-downlink OFDM symbol in the monitoring period indicated by the uplink multiplexing time-frequency resource, the 4 th group corresponds to the 4 th non-downlink OFDM symbol in the monitoring period indicated by the uplink multiplexing time-frequency resource, and the 5 th group corresponds to the 5 th non-downlink OFDM symbol in the monitoring period indicated by the uplink multiplexing time-frequency resource; i is more than or equal to 1 and less than or equal to X.
In practical application, the number of bits included in the uplink multiplexing time-frequency resource indication can be set according to protocol specification, and can also be set according to practical application scenarios. In the embodiment of the invention, the uplink multiplexing time-frequency resource comprises 14 bits.
The following describes the division of the uplink multiplexing time-frequency resource instruction, taking the example that the uplink multiplexing time-frequency resource includes 14 bits and x=5.
The value of the uplink multiplexing time-frequency resource indication is 01100000000010. The 14 bits indicated by the uplink multiplexing time-frequency resource are divided into 5 groups, and the sequence is as follows: group 1, group 2, group 3, group 4 and group 5. mod (14, 5) =4, ceil (14/5) =3, floor (14/5) =2.
Thus, groups 1 through 4 each include 3 bits, and group 5 includes 2 bits, where the value of group 1 3 bits is {011}, group 2 3 bits is {000}, group 3 bits is {000}, group 4 3 bits is {000}, and group 5 2 bits are {10}.
And dividing the uplink multiplexing time-frequency resource indication into X groups, and respectively acquiring the values of all bits in each group after obtaining the X groups of bits. For the ith group in the X groups, it can be judged whether there is a bit having a value of 1 in the ith group. In the embodiment of the invention, when the value of the j-th bit in the i-th group is judged to be 1, the time-frequency resource corresponding to the j-th bit can be judged to be multiplexed; in contrast, when it is determined that the value of the j-th bit in the i-th group is 0, it may be determined that the video resource corresponding to the j-th bit is not multiplexed.
When it is determined that the i-th group has a bit with a value of 1, the user terminal 1 may determine that the time domain resource corresponding to the uplink multiplexing time-frequency resource is: the ith non-downlink OFDM symbol in the monitoring period indicated by the uplink multiplexing time-frequency resource.
When the bit with the median of 1 in the ith group is the jth bit, the frequency domain resource corresponding to the jth bit can be determined in the mapping relation between the preset bit and the frequency domain resource.
In the embodiment of the present invention, the mapping relationship between the preset bits and the frequency domain resource may be:
when 1.ltoreq.i.ltoreq.mod (N, X), the ith group includes ceil (N/X) bits, and the former mod (N) of the ith group BWP The size of the frequency domain indication unit corresponding to each of the ceil (N/X)) bits is ceil (N) BWP Per ceil (N/X)) PRBs, post ceil (N/X) -mod (N) BWP The size of the frequency domain indication unit corresponding to each of the ceil (N/X)) bits is floor (N) BWP Ceil (N/X)) PRBs;
when mod (N, X) < i.ltoreq.X, the ith group includes floor (N/X) bits, and the previous mod (N) of the ith group BWP The size of the frequency domain indication unit corresponding to each of the floor (N/X)) bits is ceil (N) BWP Per floor (N/X)) PRBs, post floor (N/X) -mod (N) BWP The size of the frequency domain indication unit corresponding to each of the floor (N/X)) bits is floor (N) BWP (floor (N/X)) PRBs, N BWP The total number of PRBs contained for the working BWP.
Continuing to x= 5,N =14, and the partial Bandwidth (BWP) in which the user terminal 1 operates includes the total number N of PRBs BWP For example, =11, the mapping relationship between the bits and the frequency domain resource will be described.
The user terminal 1 divides the uplink multiplexing time-frequency resource indication with the length of 14 bits into 5 groups, wherein the 1 st group to the 4 th group respectively comprise 3 bits, and the 5 th group comprises 2 bits.
Of the 1 st to 4 th bits, the preceding ceil (N BWP Each of/ceil (N/X))=2 bits corresponds to a frequency domain indication unit of size ceil (N) BWP Per floor (N/X))=4 PRBs, post ceil (N/X) -mod (N) BWP The size of the frequency domain indication unit corresponding to ceil (N/X))=1 bits is 3 PRBs.
In group 5 bits, front mod (N BWP Each of floor (N/X))=1 bits corresponds to a frequency domain indication unit of size ceil (N) BWP Per floor (N/X))=6 PRBs, post floor (N/X) -mod (N) BWP Each of floor (N/X))=1 bits corresponds to a frequency domain indication unit of size floor (N) BWP /floor (N/X))=5 PRBs.
In the embodiment of the present invention, for the ith group, PRBs in the frequency domain indication units corresponding to each bit are different from each other, and PRBs corresponding to adjacent frequency domain indication units are adjacent.
For example, N BWP 11, that is, the total number of PRBs included in the BWP operated by the user terminal 1 is 11, and the 11 PRBs are PRB0 to PRB10 in order. For the 1 st group of bits, in the frequency domain, the PRB corresponding to the 1 st bit is PRB 0-PRB 3, the PRB corresponding to the 2 nd bit is PRB 4-PRB 7, and the PRB corresponding to the 3 rd bit is PRB 8-PRB 10.
In a specific implementation, after determining the uplink multiplexing time-frequency resource, the ue 1 may adjust its own uplink data transmission on the determined uplink multiplexing time-frequency resource, so as to ensure the reliability of uplink transmission of the ue with a short duration.
When the user terminal 1 adjusts the transmission of the uplink data, the uplink data transmission can be stopped, and the transmission power of the uplink data can be reduced, so that the reliability of the uplink transmission of the user terminal 2 is ensured.
It can be understood that in practical application, the ue 1 may also adjust the transmission of the uplink data by using other methods on the determined uplink multiplexing time-frequency resource, so long as the reliability of uplink transmission of the ue 2 can be ensured, which is not described herein.
In a specific implementation, the base station may configure whether the ue 1 needs to monitor one or more uplink multiplexing time-frequency resource indications. When the base station configures the user terminal 1 and needs to monitor the uplink multiplexing time-frequency resource indication, the base station can issue configuration information to the user terminal 1. In the embodiment of the present invention, the configuration information sent by the base station to the user terminal 1 may include: an instruction for monitoring is carried out, a control resource set and a search space corresponding to the monitoring are carried out, a monitoring period of the monitoring is carried out, a service cell set with a monitoring requirement exists, and a mapping relation between the service cell with the monitoring requirement and an uplink multiplexing time-frequency resource instruction exists; the load length of the configuration information is determined by the number of the service cells with monitoring requirements.
After receiving the configuration information issued by the base station, the user terminal 1 may execute steps S101 to S102. In a specific implementation, when the ue 1 does not receive the configuration information issued by the base station, the above steps S101 to S102 may not be performed.
In a specific implementation, the base station may issue configuration information to the user terminal 1 through radio resource control (Radio Resource Control, RRC) signaling. It can be understood that the base station may also send configuration information to the ue 1 through other signaling, which is not described herein.
The method for determining uplink multiplexing time-frequency resources provided in the above embodiment of the present invention is described below by way of example.
Referring to fig. 2, a BWP diagram of an eMMB user terminal in operation according to an embodiment of the present invention is shown. The eMMB user terminal is set as the user terminal 1, and the BWP corresponding to the user terminal 1 includes 11 PRBs, and PRB0 to PRB10 are sequentially set. The ue 2 is a URLLC ue, and in the working process of the ue 1, the ue 2 may multiplex the time-frequency resources of the uplink transmission of the ue 1 to perform uplink transmission.
The base station configures the monitoring period of the user terminal 1 for monitoring the uplink multiplexing time-frequency resource indication to 7 OFDM symbols through RRC signaling, as shown in fig. 2. In a listening period indicated by an uplink multiplexing time-frequency resource, the downlink OFDM symbols are OFDM symbol 0 and OFDM symbol 1, respectively, so the number of downlink OFDM symbols is 2. Therefore, in a listening period indicated by the uplink multiplexing time-frequency resource, the number of non-downlink OFDM symbols is x=7-2=5, that is, OFDM symbol 2, OFDM symbol 3, OFDM symbol 4, OFDM symbol 5, and OFDM symbol 6 are all non-downlink OFDM symbols. At this time, the user terminal 1 divides the 14 bits of the uplink multiplexed time-frequency resource indication into x=5 groups. In fig. 2, non-downlink OFDM symbols are identified by Y.
When 14 bits are divided into 5 groups, mod (14, X) =4, ceil (14/X) =3. Thus, each of the front mod (14, X) =4 groups contains ceil (14/X) =3 bits; the post X-mod (14, X) =1 group includes floor (14/X) =2 bits. That is, when 14 bits are divided into 5 groups, among the divided 5 groups: group 1 includes 3 bits, group 2 includes 3 bits, group 3 includes 3 bits, group 4 includes 3 bits, and group 5 includes 2 bits.
The frequency domain indication unit size corresponding to each of the first 4 groups, wherein each of the first mod (NBWP, ceil (14/X))=2 bits is: ceil (NBWP/ceil (14/X))=4 PRBs; the frequency domain indication unit size corresponding to post ceil (14/X) -mod (NBWP, ceil (14/X))=1 bit is floor (NBWP/ceil (14/X))=3 PRBs.
Taking the 1 st group of the previous 4 groups as an example, the 1 st group comprises 3 bits, the size of a frequency domain indication unit corresponding to each bit of the first 2 bits of the 3 bits is 4 PRBs, and the frequency domain indication resource corresponding to the last 1 bits of the 3 bits is 3 PRBs.
Corresponding to group 5, the frequency domain indication unit size corresponding to the front mod (NBWP, floor (14/X))=1 bit in the group is ceil (NBWP/floor (14/X))=6 PRBs, and the frequency domain indication unit size corresponding to the rear floor (14/X) -mod (NBWP, floor (14/X))=1 bit is floor (NBWP/floor (14/X))=5 PRBs. That is, for the 5 th group, the frequency domain indication unit size corresponding to the 1 st bit is 6 PRBs, and the frequency domain indication resource size corresponding to the 2 nd bit is 5 PRBs.
Group 1 of the x=5 groups corresponds to a first non-downlink OFDM symbol in a listening period indicated by an uplink multiplexed time-frequency resource, and a first bit in group 1 is used to indicate: whether the first non-downlink OFDM symbol in the time domain, PRB 0-PRB 3 in the frequency domain are multiplexed by the user terminal 2; the second bit in group 1 is used to indicate: whether the first non-downlink OFDM symbol in the time domain, PRB 4-PRB 7 in the frequency domain are multiplexed by the user terminal 2; the third bit in group 1 is used to indicate: whether the first non-downlink OFDM symbol in the time domain, PRB 8-PRB 10 in the frequency domain, are multiplexed by the user terminal 2.
Group 2 of the x=5 groups corresponds to a second non-downlink OFDM symbol in a listening period indicated by the uplink multiplexed time-frequency resource, and a first bit in group 2 is used to indicate: whether the second non-downlink OFDM symbol in the time domain, PRB 0-PRB 3 in the frequency domain are multiplexed by the user terminal 2; the second bit in group 2 is used to indicate: whether the second non-downlink OFDM symbol in the time domain, PRB 4-PRB 7 in the frequency domain, is multiplexed by the user terminal 2; the third bit in group 2 is used to indicate: whether the second non-downlink OFDM symbol in the time domain, PRB 8-PRB 10 in the frequency domain, is multiplexed by the user terminal 2.
Accordingly, the 3 rd group in the x=5 groups corresponds to the third non-downlink OFDM symbol in the listening period indicated by the uplink multiplexed time-frequency resource, and the first bit in the 3 rd group is used to indicate: whether the third non-downlink OFDM symbol in the time domain, PRB 0-PRB 3 in the frequency domain are multiplexed by the user terminal 2; the second bit in group 3 is used to indicate: whether the third non-downlink OFDM symbol in the time domain, PRB 4-PRB 7 in the frequency domain, is multiplexed by the user terminal 2; the third bit in group 3 is used to indicate: whether the third non-downlink OFDM symbol in the time domain, PRB 8-PRB 10 in the frequency domain, is multiplexed by the user terminal 2.
Group 4 of the x=5 groups corresponds to a fourth non-downlink OFDM symbol in a listening period indicated by the uplink multiplexed time-frequency resource, and a first bit in group 4 is used to indicate: whether the fourth non-downlink OFDM symbol in the time domain, PRB 0-PRB 3 in the frequency domain are multiplexed by the user terminal 2; the second bit in group 4 is used to indicate: whether the fourth non-downlink OFDM symbol in the time domain, PRB 4-PRB 7 in the frequency domain are multiplexed by the user terminal 2; the third bit in group 4 is used to indicate: whether the fourth non-downlink OFDM symbol in the time domain, PRB 8-PRB 10 in the frequency domain, are multiplexed by the user terminal 2.
Group 5 of the x=5 groups corresponds to a fifth non-downlink OFDM symbol in a listening period indicated by the uplink multiplexed time-frequency resource, and a first bit in group 5 is used to indicate: whether the fifth non-downlink OFDM symbol in the time domain, PRB0 to PRB5 in the frequency domain are multiplexed by the user terminal 2; the second bit in group 5 is used to indicate: whether the fifth non-downlink OFDM symbol in the time domain, PRB 6-PRB 10 in the frequency domain, is multiplexed by the user terminal 2.
The base station schedules the user terminal 1 to perform uplink transmission on the non-downlink OFDM symbols of OFDM symbols 0 to 13, and the frequency domain resource is its entire BWP. The user terminal 1 monitors and successfully decodes on the OFDM symbol 0 to obtain an uplink multiplexing time-frequency resource indication. The length of the uplink multiplexing time-frequency resource indication obtained by decoding by the user terminal 1 is 14 bits, and the value of the uplink multiplexing time-frequency resource indication is 01100000000010.
According to the grouping method described above, the user terminal 1 divides the values of the uplink multiplexed time-frequency resource indication into x=5 groups, wherein: the values of the bits of group 1 are: {011}; the values of the bits of group 2 are: {000}; the values of the bits of group 3 are: {000}; the values of the bits of group 4 are: {000}; the values of the bits of group 5 are: {10}.
The user terminal 1 may determine, according to the value of each bit in each group, that the time-frequency resources multiplexed by the user terminal 2 are: the time domain is OFDM symbol 2, the frequency domain is PRB 4-PRB 7, PRB 8-PRB 10; the time domain is OFDM symbol 6, and the frequency domain is PRB 0-PRB 5.
The user terminal 1 stops transmitting uplink data on time-frequency resources with the time domain of OFDM symbol 2, the frequency domain of PRB 4-PRB 7 and PRB 8-PRB 10; on the time-frequency resources with the time domain of OFDM symbol 6 and the frequency domain of PRB 0-PRB 5, the transmission power of the uplink data is reduced.
Referring specifically to fig. 2, the black line filling part in fig. 2 is the uplink time-frequency resource multiplexed by the user terminal 2.
It can be seen that, in the embodiment of the present invention, the base station sends an uplink multiplexing time-frequency resource indication to the long-duration user terminal. The long-duration user terminal monitors according to the monitoring period indicated by the uplink multiplexing time-frequency resource, and determines the uplink multiplexing time-frequency resource according to the uplink multiplexing time-frequency resource indication in one monitoring period, so that the long-duration user terminal can acquire a physical resource block for uplink multiplexing on a frequency domain corresponding to the uplink multiplexing time-frequency resource and an OFDM symbol for uplink multiplexing on a time domain.
