Description

Resource mapping method and device
Technical Field
The present invention relates to the field of communications, and in particular, to a resource mapping method and apparatus.
Background
At present, in an NR (New Radio, New air interface) communication system, HARQ-ACK (Hybrid Automatic Repeat reQuest acknowledgement) may be transmitted through PUSCH (Physical Uplink Shared Channel).
When the number of information bits of the HARQ-ACK is greater than 2, the HARQ-ACK and other information on the PUSCH are multiplexed and transmitted by means of rate matching, and an explicit HARQ-ACK mapping rule has been defined so far, for example: the HARQ-ACK is mapped sequentially according to a mode of first frequency domain and then time domain after a first DMRS (Demodulation Reference Signal) symbol; the current working assumption is that if RE (Resource Element) resources occupied by HARQ-ACK do not occupy a whole OFDM (Orthogonal Frequency Division Multiplexing) symbol, or RE resources occupied by HARQ-ACK are more than one OFDM symbol but RE resources on all PUSCH bandwidths cannot be occupied on the last symbol, then the mapping is spread evenly over the Frequency domain. For example, when the resource of the HARQ-ACK is not full of one symbol, the frequency domain interval is the number of REs available on the symbol/the number of remaining unmapped HARQ-ACK symbols and rounded down.
When the information bit number of the HARQ-ACK is 0 or 1 or 2, the HARQ-ACK and other information on the PUSCH are multiplexed and transmitted in a puncturing mode. In order to avoid that the HARQ-ACK punctures the CSI (Channel state information) part 1 to affect the transmission performance of the CSI part 1, it is specified that a part of resources need to be reserved, and the CSI part 1 is not mapped on the reserved RE resources. Currently, the reserved resources are determined according to the HARQ-ACK information as 2 bits, that is, the number of RE resources occupied by the actual HARQ-ACK information may be less than the number of reserved RE resources.
At present, the working assumption is that the same mapping method is used for the reserved HARQ-ACK resources and the HARQ-ACK with the bit more than 2, the actual HARQ-ACK resources can only occupy one part of the reserved HARQ-ACK resources, but no specific method exists for determining the RE resources occupied by the actual HARQ-ACK information. And if the actual HARQ-ACK resources reuse the mapping method of HARQ-ACK of more than 2 bits as well, the actual HARQ-ACK resources may be mapped outside the reserved HARQ-AC resources in some cases. Therefore, how to determine the RE resources occupied by the actual HARQ-ACK information is urgent to solve.

The following description is given of specific application scenarios of the resource mapping method according to the embodiment of the present invention:
scene one: in a slot of a slot, HARQ-ACK needs to be mapped on a PUSCH for transmission, the bit number of the HARQ-ACK needing to be transmitted in the slot is 1, the CRC bit number is 0, the bit number of PUSCH data needing to be transmitted in the slot is 640, the number of REs which can be used for transmitting UCI or data is 72, and the base station configures the number of REs
Figure BDA0001578763890000108
Is 20, and the value of α configured by the base station is 1, the resource quantity (number of REs) of the reserved resources of HARQ-ACK on PUSCH is calculated as follows according to the above equation (4):
Figure BDA0001578763890000109
the number of modulation symbols of HARQ-ACK actually required to be transmitted on PUSCH is calculated according to equation (4) above as follows:
Figure BDA00015787638900001010
by applying the resource mapping method of the embodiment of the invention, when the bit number of the HARQ-ACK needing to be transmitted is 1, the relative distance between the adjacent HARQ-ACK modulation symbols in the reserved resources can be determined according to the result of whether the resource quantity of the reserved resources exceeds the resource quantity which can be used for transmitting the HARQ-ACK. In the scenario one, it can be seen that the number of reserved resources includes 5 REs, and the number of resources available for transmitting HARQ-ACK includes 72 REs, that is, the number of reserved resources does not exceed the number of resources available for transmitting HARQ-ACK, and then the relative distance between adjacent HARQ-ACK modulation symbols in the reserved resources is 2 REs. As shown in fig. 2, assuming that the results of numbering the 5 REs occupied by the HARQ-ACK reserved resources according to the sequence of frequency domain first and time domain second are REs 0 to RE4, the 3 modulation symbols of the HARQ-ACK are sequentially mapped on RE0, RE2, and RE 4. At this time, the actual HARQ-ACK resources are completely mapped in the reserved resources, and the HARQ-ACK modulation symbols are distributed on the PUSCH as discretely as possible.
Scene two: in a slot of a slot, HARQ-ACK needs to be mapped on a PUSCH for transmission, the bit number of the HARQ-ACK needing to be transmitted in the slot is 1, the CRC bit number is 0, the bit number of PUSCH data needing to be transmitted in the slot is 176, the number of REs which can be used for transmitting UCI or data is 60, and the base station configures the number of REs
Figure BDA0001578763890000111
Is 80, and the value of α configured by the base station is 0.65, the resource quantity (number of REs) of the reserved resources of HARQ-ACK on PUSCH is calculated as follows according to the above equation (4):
Figure BDA0001578763890000112
the number of modulation symbols of HARQ-ACK actually required to be transmitted on PUSCH is calculated according to equation (4) above as follows:
Figure BDA0001578763890000113
by applying the resource mapping method of the embodiment of the invention, when the bit number of the HARQ-ACK which needs to be transmitted is 1, the relative distance between the adjacent HARQ-ACK modulation symbols in the reserved resources can be determined according to the result of whether the resource quantity of the reserved resources exceeds the resource quantity which can be used for transmitting the HARQ-ACK. In the second scenario, it can be seen that the number of reserved resources includes 39 REs, and the number of resources available for transmitting HARQ-ACK includes 60 REs, that is, the number of reserved resources exceeds the number of resources available for transmitting HARQ-ACK, then the relative distance d between adjacent HARQ-ACK modulation symbols in the reserved resources according to formula (1) is: and d is floor (39/28) is 1, namely the relative distance between different HARQ-ACK modulation symbols in the HARQ-ACK reserved resources is mapped to 1 RE. As shown in fig. 3, assuming that the 39 REs occupied by the HARQ-ACK reserved resources are respectively RE0 to RE38 according to the result of numbering the frequency domain first and then the time domain, 28 modulation symbols of the HARQ-ACK are sequentially mapped on RE0 to RE27 respectively. At this time, the actual HARQ-ACK resource is completely mapped in the reserved resource, and the realization is simple and the standard complexity is small.
Optionally, the step 101 includes:
step 1012: and determining the relative distance between the adjacent HARQ-ACK modulation symbols in the reserved resources according to the number of the HARQ-ACK modulation symbols needing to be transmitted and the number of the reserved resources.
Here, an applicable resource mapping strategy can be determined according to the number of the modulation symbols of the HARQ-ACK which need to be transmitted actually and the number of the resources of the reserved resources, that is, the relative distance between the adjacent HARQ-ACK modulation symbols in the reserved resources is determined, so that a determination scheme of the HARQ-ACK information transmission resources on the PUSCH is provided, the implementation is simple, the actual HARQ-ACK resources can be guaranteed to be completely mapped in the reserved resources, and the HARQ-ACK modulation symbols are guaranteed to be distributed discretely on the PUSCH as much as possible.
Optionally, step 1012 includes:
step 10121: determining a relative distance d between adjacent HARQ-ACK modulation symbols in the reserved resources by:
Figure BDA0001578763890000121
wherein, X represents the resource quantity of the reserved resource, Y represents the quantity of the HARQ-ACK modulation symbols needing to be transmitted, and ceiling represents an upward rounding function.
At this time, the relative distance between the adjacent HARQ-ACK modulation symbols in the reserved resources is determined through the formula (2), so that the actual HARQ-ACK resources can be completely mapped in the reserved resources, and the HARQ-ACK modulation symbols are distributed on the PUSCH as discretely as possible.
For example, in the scenario one described above, Y is 3, ceil (X/2) is 3, and thus Y is ceil (5/2) is 3, and thus Y is ceil (X/2), and the relative distance d between adjacent HARQ-ACK modulation symbols in the reserved resources is 2, that is, the relative distance between different HARQ-ACK modulation symbols in the HARQ-ACK reserved resources is mapped to 2 REs by using the above formula (2). As shown in fig. 2, assuming that the results of numbering the 5 REs occupied by the HARQ-ACK reserved resources according to the sequence of frequency domain first and time domain second are REs 0 to RE4, the 3 modulation symbols of the HARQ-ACK are sequentially mapped on RE0, RE2, and RE 4. At this time, the actual HARQ-ACK resources are completely mapped in the reserved resources, and the HARQ-ACK modulation symbols are distributed on the PUSCH as discretely as possible.
In the aforementioned scenario two, Y is 28, while leaving (X/2) is 20, so Y > leaving (X/2), and it can be obtained through the above formula (2) that the relative distance d between adjacent HARQ-ACK modulation symbols in the reserved resources is 1, that is, the relative distance between different HARQ-ACK modulation symbols in the HARQ-ACK reserved resources is 1 RE for mapping. As shown in fig. 3, assuming that the 39 REs occupied by the HARQ-ACK reserved resources are respectively RE0 to RE38 according to the result of numbering the REs in the order of frequency domain first and time domain second, 28 modulation symbols of the HARQ-ACK are sequentially and respectively mapped on RE0 to RE 27. At this time, the actual HARQ-ACK resources are completely mapped in the reserved resources, and the realization is simple and the standard complexity is small.

At this time, the actual HARQ-ACK resources are completely mapped in the reserved resources, and the HARQ-ACK modulation symbols are distributed on the PUSCH as discretely as possible.
In the second scenario described above, the relative distance d between adjacent HARQ-ACK modulation symbols in the reserved resources can be obtained by the above equation (3) as:
Figure BDA0001578763890000141
i.e. the relative distance between different HARQ-ACK modulation symbols in the HARQ-ACK reserved resources is mapped to 1 RE. As shown in fig. 3, assuming that the 39 REs occupied by the HARQ-ACK reserved resources are respectively RE0 to RE38 according to the result of numbering the REs in the order of frequency domain first and time domain second, 28 modulation symbols of the HARQ-ACK are sequentially and respectively mapped on RE0 to RE 27. At this time, the actual HARQ-ACK resources are completely mapped in the reserved resources, and the realization is simple and the standard complexity is small.
