Description

Resource mapping methods, storage media, electronic devices and computer program products Technical Field

[0001] This application relates to the field of communications, such as resource mapping methods, storage media, electronic devices, and computer program products. Background Technology

[0002] In traditional wireless communication systems, data to be transmitted is first mapped to a virtual resource block (VRB), and then mapped from the VRB to a physical resource block (PRB). The VRB is a logical frequency domain resource, facilitating network management and planning of frequency domain resources, while the PRB is a physical frequency domain resource, representing the actual frequency domain resources that carry and transmit information. On an active Bandwidth Part (BWP), the number of VRBs and corresponding PRBs remains consistent. When a higher layer configures interleaved VRB-to-PRB mapping, a VRB-to-PRB mapping pattern needs to be generated according to the size of the active BWP (i.e., all PRBs on the active BWP that can be used for Physical Downlink Shared Channel (PDSCH) transmission). Figure 1 illustrates a traditional resource mapping process provided by related technologies. The traditional interleaved VRB-to-PRB mapping process, as shown in Figure 1, necessitates that PDSCHs transmitted on the active BWP to the same or different devices must use the interleaved VRB-to-PRB mapping method.

[0003] For example, on a downlink active BWP, the base station schedules 100 PRBs for PDSCH transmission of device 1 and configures an interleaved VRB-to-PRB mapping method through higher-layer signaling. Meanwhile, device 2 needs to have 4 PRBs scheduled for its PDSCH transmission. Figure 2 is a schematic diagram of a traditional resource mapping process for PDSCH transmission of a small number of resource blocks (RBs) provided by related technologies. The resource mapping rules for PDSCH transmission of the 4 PRBs of device 2 are shown in Figure 2. According to the traditional interleaved VRB-to-PRB mapping process, the resource mapping of these 4 PRBs also needs to be mapped according to the interleaved mapping pattern, and they are scattered across PRBs numbered 0, 1, 136, and 137 for transmission. At this time, the base station needs to generate at least a 137*12-length demodulation reference signal (DMRS), channel state information-reference signal (CSI-RS), or phase tracking reference signal (PTRS), from which it extracts the corresponding 4*12 resource particles. The reference signal information for the (Element, RE) positions is mapped to the corresponding RE positions in the four scrambled PRBs and sent to device 2 along with the data. Device 2, in turn, needs to extract the reference signal information for the corresponding 4*12 RE positions from at least a 137*12 length DMRS, CSI-RS, or PTRS and store it for data demodulation. This significantly increases the complexity of resource mapping for PDSCH transmission, hinders frequency division multiplexing and space division multiplexing of PDSCH across multiple devices, and limits scheduling flexibility. Summary of the Invention

[0004] This application provides resource mapping methods, storage media, electronic devices, and computer program products to at least solve the problems in related technologies where interleaved VRB-to-PRB mapping increases the complexity of PDSCH resource mapping and limits the frequency division multiplexing and scheduling flexibility of PDSCH transmission.

[0007] According to another embodiment of this application, an electronic device is also provided, including a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to implement the above-described resource mapping method.

[0008] According to yet another embodiment of this application, a computer program product is also provided, including a computer program that, when executed by a processor, implements the above-described resource mapping method.

[0009] In this embodiment, the mapping of interleaved data information to virtual resource blocks, or the mapping of interleaved virtual resource blocks to physical resource blocks, is performed only on the frequency domain resources allocated for uplink or downlink data transmission. Compared with the traditional mapping operation based on interleaving for all RBs on an active BWP, this embodiment can reduce the complexity of data channel resource mapping, obtain frequency domain diversity gain, improve anti-interference capability, and achieve the effects of energy saving and improved resource scheduling flexibility.

The first information after interleaving is then sequentially mapped to the PRBs in the interleaved or ascending order of the PRB indices. Figure 6 is a schematic diagram of an interleaved mapping structure for information to resource blocks based on information grouping provided in an embodiment of this application. As shown in Figure 6, for the interleaved VRB to PRB mapping, the interleaved PRB index order is {0,1,136,137,2,3,...,272}, and the first information after interleaving is... Then information I0 is mapped to the first RE of PRB number 0, information I 24 Mapped to the first RE of PRB number 136.

[0047] C1 divides the first number of virtual resource blocks into Q virtual resource unit groups, where U is the size of the virtual resource unit group. The first Q-1 virtual resource unit groups each contain U REs, and the Qth or Q-1 virtual resource unit group contains N. RB *n-(Q-1)*U RE or Q*U-mod(Q*U,N RB *n) REs; the virtual resource unit group numbered q is interleaved to form the corresponding virtual resource unit group numbered f(q), where f(q) = rT + t, q = tR + r, r = 0, 1, ..., R-1, t = 0, 1, ..., T-1; R is the interleaving depth. The virtual resource unit group numbered Q-1 is interleaved to form the corresponding virtual resource unit group numbered Q-1.

[0049] C3, according to the interleaved or non-interleaved VRB to PRB mapping operation, maps the information on the first number of virtual resource blocks to the first number of physical resource blocks.

[0050] C2 and C3 can be combined into one operation. Based on the interleaved or non-interleaved VRB to PRB mapping operation, an interleaved or non-interleaved PRB number sequence is generated. The complex numerical symbols on the interleaved VRBs are then sequentially mapped to the PRBs corresponding to the interleaved or non-interleaved PRB number sequence. Figure 7 is a schematic diagram of an interleaved mapping structure from information to resource blocks based on a virtual resource unit group provided in an embodiment of this application. As shown in Figure 7, assuming n = 12 and R = 2, for the first information to VRB mapping of the interleaved VRBs, the virtual resource unit group size is 24. After completing the mapping of the first information to VRBs, the first information on the first number of VRBs is {I0, I1, I2, I3, ..., I...} M-1 For interleaved VRB to PRB mapping, if the PRB bundle size is 2 RBs, then the interleaved PRB numbering order is {0,1,136,137,2,3,...,272}. Information I0 is mapped to the first RE of the PRB numbered 0. 24 Mapped to the first RE of PRB number 136. For non-interleaved VRB to PRB mapping, the non-interleaved PRB index order is {0,1,2,3,...,272}. After completing the mapping of the first information of the interleaved VRB to the VRB, the first information on the first number of VRBs is {I0,I1,I2,I3,...,I...}.

Based on the interleaved VRB numbering sequence and the interleaved or non-interleaved PRB numbering sequence, a final PRB numbering sequence corresponding to the VRB with an ascending sequence number q is generated. The M consecutive complex value symbols of the first information are sequentially mapped to the PRBs corresponding to the final PRB numbering sequence. For example, assuming the interleaving depth R = 2, the virtual resource unit group size is 24, 272 RBs are allocated for transmitting PDSCH, the interleaved VRB numbering sequence is {0,1,136,137,2,3,...,272}, the virtual resource unit group size is 2 RBs, the active BWP size is 272 PRBs, and the interleaved PRB index order is {0,1,136,137,2,3,...,272}, then the final PRB numbering sequence is {0,1,68,69,136,137,...,272}, and the first information {S0,S1,S2,S3,...,S...} M-1Information S0 in the PRB is mapped to the first RE of the PRB with the number 0. 24 Mapped to the first RE of PRB number 68. For example, if the interleaved VRB numbering sequence is {0,1,136,137,2,3,...,272} and the non-interleaved PRB index order is {0,1,2,3,...,272}, then the final PRB numbering sequence is {0,1,136,137,2,3,...,272}, and the first information is {S0,S1,S2,S3,...,S...}.
