Fig. 2 is a schematic flow chart of an information transmission method according to an embodiment of the present invention, and as shown in fig. 2, an embodiment of the present invention provides an information transmission method, including:
step 101: in transmission resources of a Physical Uplink Shared Channel (PUSCH), determining reserved quantity target resources for transmitting Uplink Control Information (UCI), wherein the reserved quantity target resources are distributed discretely on a frequency domain.
The reserved quantity is equal to the quantity of the resources needing to be mapped by the UCI, and the quantity of the resources needing to be mapped by the UCI represents the number of modulation symbols which are not mapped by the UCI. The reserved number target resource may specifically be a reserved number target resource unit RE of one OFDM symbol, and the reserved number target resource is distributed discretely (distributed) in frequency according to the same frequency interval or different frequency intervals. The UCI comprises: acknowledgement ACK message or non-acknowledgement NACK message transmitted upstream in PUSCH.
Here, the reserved target resources are distributed discretely in the frequency domain, so that the frequency diversity gain (diversity gain) can be effectively increased, and the transmission reliability is improved.
Step 102: and mapping the actually transmitted UCI to the reserved quantity target resources, and transmitting in the target resources.
The number of the UCI resources actually transmitted is less than the reserved number, and the ACK message or the NACK message is transmitted by puncturing (puncturing), and the UCI actually transmitted is mapped to the target resources of the reserved number which are discretely distributed in the frequency domain, so that the frequency diversity gain can be effectively increased, and the transmission reliability can be improved.
Further, the step 101 of determining a reserved target number of resources for transmitting uplink control information UCI in the transmission resources of the physical uplink shared channel PUSCH includes:
calculating a first frequency interval of the discrete distribution of the reserved quantity of target resources on a frequency domain; determining a first target resource according to the first frequency interval in available resources; and if the resource quantity of the first target resource is less than the reserved quantity, determining a second target resource in the remaining available resources according to a second frequency interval.
The second frequency interval is obtained by subtracting a preset value from the first frequency interval, namely the second frequency interval is smaller than the first frequency interval.
Here, the sum of the resource amounts of the first target resource and the second target resource is less than or equal to the reserved amount, and if the sum of the resource amounts of the first target resource and the second target resource is equal to the reserved amount, the determination of the target resource is stopped, and if the sum of the resource amounts of the first target resource and the second target resource is less than the reserved amount, the target resource is continuously determined at sequentially decreasing frequency intervals.
Specifically, if the sum of the resource quantities of the determined target resources is smaller than the reserved quantity, the target resources are continuously determined in the remaining available resources according to the target frequency interval smaller than the second frequency interval until the sum of the determined target resources is equal to the reserved quantity.
The frequency intervals in the embodiments of the present invention decrease in sequence. Wherein the first frequency interval is obtained by: acquiring a ratio of the number of available resources in the transmission resources to the reserved number, where the number of available resources may refer to a resource of one OFDM symbol or a resource of multiple OFDM symbols, and the number of resources to be mapped by UCI may refer to the number of modulation symbols that have not been mapped in one OFDM symbol or the number of modulation symbols that have not been mapped in multiple OFDM symbols; and rounding the ratio to obtain the first frequency interval. Assuming that the number of available REs in the transmission resource is 24 and the reserved number is 13, the ratio of the two is rounded up to 2, i.e. the first frequency interval is two REs apart in the frequency domain.
For example, the second frequency interval is different from the first frequency interval by one RE in the frequency domain, and assuming that the first frequency interval is three REs apart in the frequency domain, the second frequency interval may specifically be two REs apart in the frequency domain, and the target resources are determined by the first frequency interval and the second frequency interval, so that the frequency interval between the target resources can be kept to the maximum, and the reliability of transmission is further improved.
Further, the determining the first target resource according to the first frequency interval includes:
among available resources, the first target resource is determined in a direction from a high frequency to a low frequency or from a low frequency to a high frequency, according to the first frequency interval.
In the embodiment of the present invention, when determining the first target resource according to the first frequency interval, the first target resource may be determined according to a direction from a high frequency to a low frequency or from a low frequency to a high frequency, and of course, the first target resource may also be determined according to other mapping rules, which is not limited specifically herein.
Further, the determining a second target resource according to the second frequency interval includes:
and determining the second target resource in the direction from the high frequency to the low frequency or from the low frequency to the high frequency according to the second frequency interval in the remaining available resources.
For example, the first frequency interval is three REs apart, and the second frequency interval is two REs apart, as shown in fig. 3a, the first target REs are first mapped according to the first frequency interval, such as the hatched portion in the figure, and the remaining target REs are mapped according to the second frequency interval, such as the vertical portion in fig. 3a, in the remaining resources, sequentially mapped from the low frequency to the high frequency. And mapping the rest UCI symbols in turn according to the method. Fig. 3b is a mapping in order starting from a high frequency to a low frequency. Of course, the first target resource may also be determined according to other mapping rules, which are not limited herein.
Further, the step 102 of mapping the actually transmitted UCI onto the reserved number of target resources includes:
mapping the UCI actually transmitted to the reserved quantity target resources according to the direction from high frequency to low frequency;
or, according to the direction from low frequency to high frequency, mapping the UCI actually transmitted to the target resource with the reserved quantity;
or, according to the direction from the middle frequency to the two end frequencies, mapping the UCI actually transmitted to the target resource with the reserved quantity;
or, mapping the actually transmitted UCI to the reserved number target resource according to the direction from the two end frequencies to the middle frequency.
The direction from the high frequency to the low frequency is to map from the target resource with the highest frequency to the target resource with the lowest frequency in the reserved quantity of target resources, and the direction from the low frequency to the high frequency is to map from the target resource with the lowest frequency to the target resource with the highest frequency in the reserved quantity of target resources; the intermediate frequency refers to an intermediate frequency of the reserved quantity of target resources, and the two-end frequencies refer to a frequency corresponding to a target resource with the highest frequency and a frequency corresponding to a target resource with the lowest frequency in the reserved quantity of target resources.
In fig. 4 a-4 d, the first column is a DMRS symbol, the second column contains resources reserved for HARQ-ACK and maps ACK/NACK for transmitting actual transmission, and the HARQ-ACK reserved resources are not used by ACK/NACK. The partial resources may be used as other UCI information or data. Wherein fig. 4a maps UCI in a direction from high frequency to low frequency; fig. 4b maps UCI in a direction from low frequency to high frequency; fig. 4c maps UCI in a direction from a middle frequency to both end frequencies; fig. 4d maps UCI in the direction from both end frequencies to the middle frequency.
The present invention may be applied to determine resource mapping of control information carried in the same or different numerical configuration (numerology) in NR in a data channel.
In the information transmission method of the embodiment of the invention, the reserved quantity target resources for transmitting the uplink control information UCI are determined in the transmission resources of the physical uplink shared channel PUSCH, the actually transmitted UCI is mapped to the reserved quantity target resources and is transmitted in the target resources, and the reserved quantity target resources are distributed discretely in the frequency domain, so that the frequency diversity gain can be effectively increased, and the transmission reliability is improved.
