Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a frequency domain resource allocation method, apparatus, and device. Background Technology

[0002] Currently, NR (New Radio) has many discontinuous, small-bandwidth spectrum segments. If the spectrum usage follows the previous methods, terminals can only aggregate these carriers, but a TB (transmission block) can only be transmitted within one carrier. Because the bandwidth of each carrier is very small, it cannot support larger TB sizes. For a service packet, the base station can only split it into multiple smaller TBs for transmission, requiring multiple PDCCHs (Physical Downlink Control Channels) for scheduling, resulting in significant PDCCH overhead. Furthermore, because the bandwidth of each carrier is small, it cannot support larger aggregation levels of PDCCHs, thus limiting the throughput of carrier usage. Summary of the Invention

[0052] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0053] like Figure 1 As shown, an embodiment of the present invention provides a frequency domain resource allocation method applied to a network-side device, the method comprising:

[0054] Step 11: Send downlink control information (DCI) to the terminal. The DCI is used to indicate the frequency domain resource allocation of the physical shared channel, and the frequency domain resources of the physical shared channel are located within one or more frequency domain resource ranges.

[0055] In this embodiment, downlink control information (DCI) can be sent to the terminal. The DCI indicates the frequency domain resource allocation of the physical shared channel, where the frequency domain resources are located within one or more frequency domain resource ranges. This allows for scheduling of multiple different frequency domain resource ranges within a single DCI, improving carrier throughput and reducing the overhead of the downlink control channel (PDCCH).

[0056] In an optional embodiment of the present invention, in step 11, the DCI includes a first information domain and a second information domain;

[0057] The first information field is used to indicate the index of one or more frequency domain resource ranges in which the frequency domain resources of the physical shared channel are located;

[0058] The second information field is used to indicate the allocation of frequency domain resources within a frequency domain resource range.

[0059] The frequency domain resource range is the carrier or bandwidth portion (BWP).

[0060] In this embodiment, the second information field is specifically used to indicate the resource allocation of the frequency domain resources of the Physical Downlink Shared Channel (PDSCH) / Physical Uplink Shared Channel (PUSCH) within a carrier or bandwidth portion (BWP). The second information field is shared across multiple frequency domain resource ranges; that is, the frequency domain resource allocation indicated by the second information field is referenced across multiple frequency domain resource ranges, thus saving on the PDCCH load and improving PDCCH throughput.

[0061] In another optional embodiment of the present invention, the first information domain uses a bitmap or codepoint method to indicate the index of the one or more frequency domain resource ranges.

[0062] In this embodiment, the first information domain uses a bitmap or codepoint method to indicate the index of at least one frequency domain resource where the actually scheduled Physical Downlink Shared Channel (PDSCH) / Physical Uplink Shared Channel (PUSCH) resides. For example, with five carrier / bandwidth portions (BWPs), 5 bits can be used... Figure 5 The bitmap indicates which carrier / bandwidth portions of the BWP are being scheduled.

[0063] When actually scheduling at least two target frequency domain resources, it is also possible to extract the combined configuration of some carrier / bandwidth portion BWPs configured in the base station, and then indicate the combination or configuration index through the first information field.

[0064] In another optional embodiment of the present invention, the frequency domain resource range includes: a first frequency domain resource range with the smallest bandwidth and at least one second frequency domain resource range other than the first frequency domain resource range.

[0065] In this embodiment, the first frequency domain resource range is the frequency domain resource range with the smallest bandwidth among at least two frequency domain resource ranges.

[0066] In another optional embodiment of the invention, the bit length of the second information domain is equal to the bit length of the resource allocation determined according to the bandwidth of the first frequency domain resource range.

[0067] In this embodiment, the terminal combines the first information domain and the second information domain to determine at least one frequency domain resource range to be scheduled, as well as the frequency domain resource allocation within the scheduled frequency domain resource range. The frequency domain resource allocation of the physical channels within the multiple scheduled frequency domain resource ranges is referenced to the indication in the second information domain. Considering that the bandwidth sizes of the multiple frequency domain resource ranges may differ, the length of the second information domain in this embodiment is determined based on the bandwidth of the smallest frequency domain resource range. That is, regardless of the combination of the indices of the scheduled frequency domain resource ranges indicated by the first information domain, the size of the second information domain is fixed, and the DCI load size is also fixed, simplifying the complexity of the terminal receiving the PDCCH.

[0068] In another optional embodiment of the present invention, when the frequency domain resource allocation is type 1 (e.g., continuous resource allocation), the starting resource block RB of the second frequency domain resource range corresponding to the resource indication value (RIV) contained in the second information field is:

[0069]

[0070] The number of RBs allocated consecutively is

[0071] in, It is the bandwidth size of the first frequency domain resource range / the number of physical resource blocks (PRBs);

[0072] K is the ratio of the bandwidth of the second frequency domain resource range to that of the first frequency domain resource range, for example...

[0073] In this embodiment, the scheduling frequency domain resource range indicated in the first information domain includes the second frequency domain resource range. For the second frequency domain resource range, the frequency domain resource location occupied by the Physical Downlink Shared Channel (PDSCH) or Physical Uplink Shared Channel (PUSCH) scheduled within the second frequency domain resource range is determined by the above method.

[0074] If the scheduling frequency domain resource range indicated in the first information domain includes the first frequency domain resource range, then for the first frequency domain resource range, the frequency domain resource location occupied by the Physical Downlink Shared Channel (PDSCH) or Physical Uplink Shared Channel (PUSCH) scheduled within the first frequency domain resource range is determined according to the existing method.

[0075] In another optional embodiment of the invention, when the frequency domain resource allocation is type 0 (e.g., discontinuous resource allocation), the bits of the second information field correspond to the RBG (resource block group) of the second frequency domain resource range, wherein,

[0076] The size of the first RBG is

[0077] if The size of the last RBG is Otherwise, the size of the last RBG is P*K; the size of the other RBGs is P*K.

[0078] Where P is the size of the RBG of the first frequency domain resource range, and K is the ratio of the bandwidth of the second frequency domain resource range to that of the first frequency domain resource range. This represents the starting resource location within the second frequency domain resource range. The bandwidth size of the second frequency domain resource range / the number of physical resource blocks (PRBs).

[0079] In this embodiment, the scheduling frequency domain resource range indicated in the first information domain includes the second frequency domain resource range. For the second frequency domain resource range, the frequency domain resource location occupied by the Physical Downlink Shared Channel (PDSCH) or Physical Uplink Shared Channel (PUSCH) scheduled within the second frequency domain resource range is determined by the above method.

[0080] If the scheduling frequency domain resource range indicated in the first information domain includes the first frequency domain resource range, then for the first frequency domain resource range, the frequency domain resource location occupied by the Physical Downlink Shared Channel (PDSCH) or Physical Uplink Shared Channel (PUSCH) scheduled within the first frequency domain resource range is determined according to a preset method.

[0081] like Figures 2 to 4 As shown, current NR networks contain many discontinuous, small-bandwidth spectra. Figures 2 to 4 The diagrams show three different carrier / bandwidth portion BWPs. For multiple non-contiguous small carriers / BWPs, a DCI can be used for scheduling, so that a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH) can be mapped onto at least one non-contiguous frequency domain resource.

[0082] For example, a base station sends a DCI to a terminal. This DCI is used to schedule the Physical Downlink Shared Channel (PDSCH) or the Physical Uplink Shared Channel (PUSCH). The frequency domain resource range indicated by the first information field of the DCI includes... Figure 2 , Figure 3 and Figure 4 In the case of at least one of the carrier / bandwidth portions (BWPs) shown, the terminal combines the first information domain and the second information domain to determine at least one frequency domain resource range to be scheduled, as well as the bit length of the frequency domain resource allocation within the scheduled frequency domain resource range and the position of the frequency domain resource allocation within the scheduled frequency domain resource range.

[0083] Here, the first frequency domain resource range can be as follows: Figure 2 The carrier shown, the second frequency domain resource range can be as follows: Figure 3 or Figure 4 The carrier / BWP shown has a first frequency domain resource range that is the frequency domain resource range with the smallest bandwidth among at least one frequency domain resource range; the second information field of the DCI indicates that these scheduled frequency domain resources are allocated according to the bandwidth of the first frequency domain resource range, that is, according to a bandwidth of 10M. In other words, the bit length of the allocated frequency domain resources is equal to the bit length of the frequency domain resource indication determined according to the first frequency domain resource range.

[0084] So, for such Figure 3 and Figure 4 The second frequency domain resource range shown, if the frequency domain resource range indicated by the first information domain includes Figure 3 and / or Figure 4 The aforementioned frequency domain resource range requires mapping the 20M and 30M frequency domain resources according to the bit length allocated for the 10M frequency domain resources. Specifically, during the mapping process...

[0085] 1) For resource allocation type 1 (continuous resource allocation):

[0086] The terminal interprets the RIV (Resource Indication Value) indicated in the second information field, where the starting RB corresponding to the RIV is... The number of RBs allocated consecutively is in, It is the bandwidth size of the first frequency domain resource range divided by the number of PRBs; K is the ratio of the bandwidth of the second frequency domain resource range to that of the first frequency domain resource range, for example...

[0087] For example, for Figure 3 The frequency domain resource range, K=2; for Figure 4 The frequency domain resource range, K=3.

[0088] 2) For resource allocation type 0 (non-contiguous resource allocation)

[0089] The terminal interprets the bitmap indicated by the second information field.

[0090] The bits in the second information field correspond to the resource block group (RBG) of the second frequency domain resource range, wherein the size of the first RBG is

[0091] if The size of the last RBG is Otherwise, the size of the last RBG is P*K; the size of the remaining RBGs is P*K.

[0092] Where P is the size of the RBG in the first frequency domain resource range, and K is the ratio of the bandwidth of the second frequency domain resource range to that of the first frequency domain resource range. or This represents the starting resource location within the second frequency domain resource range. The bandwidth size of the second frequency domain resource range / the number of physical resource blocks (PRBs).

[0093] For example, for Figure 3 The frequency domain resource range, K=2; for Figure 4 The frequency domain resource range, K=3.

[0094] This approach increases throughput by using multiple carriers, maps a single TB packet to non-contiguous frequency domain resources, reduces the complexity of processing multiple TB packets at the terminal, and avoids adding a new Physical Downlink Control Channel (PDCCH). Simultaneously, the Physical Uplink Shared Channel (PUSCH) sent by the terminal to the base station can also be mapped to the same frequency domain resource as the PDSCH.

[0095] In the above embodiments of the present invention, by sending Downlink Control Information (DCI) to the terminal, the DCI is used to indicate the frequency domain resource allocation of the Physical Shared Channel, wherein the frequency domain resources of the Physical Shared Channel are located within one or more frequency domain resource ranges. This reduces network-side signaling overhead by reducing the number of DCIs, while enabling flexible single / multi-carrier / frequency domain resource / BWP scheduling, and mapping a TB packet to non-contiguous frequency domain resources, thus reducing the complexity of the terminal processing multiple TB packets. Simultaneously, by defining the first and second frequency domain resource ranges, the length of the second information domain is determined, reducing the number of different DCI load sizes and lowering the complexity of the terminal detecting the PDCCH.

[0096] Embodiments of the present invention also provide a method for receiving frequency domain resource indication, applied to a terminal, the method comprising:

[0103] Optionally, the bit length of the second information field is equal to the bit length of the resource allocation determined according to the bandwidth of the first frequency domain resource range.

[0104] Optionally, when the frequency domain resource allocation is type 1, the starting resource block RB of the second frequency domain resource range corresponding to the resource indication value RIV contained in the second information field is:

[0105]

[0106] The number of RBs allocated consecutively is

[0107] in, It is the bandwidth size of the first frequency domain resource range / the number of physical resource blocks (PRBs);

[0108] K is the ratio of the bandwidth of the second frequency domain resource range to that of the first frequency domain resource range.

[0109] Optionally, when the frequency domain resource allocation is type 0, the bits of the second information domain correspond to the resource block group RBG of the second frequency domain resource range, wherein...

[0110] The size of the first RBG is

[0111] if The size of the last RBG is Otherwise, the size of the last RBG is P*K; the size of the other RBGs is P*K.

[0112] Where P is the size of the RBG of the first frequency domain resource range, and K is the ratio of the bandwidth of the second frequency domain resource range to that of the first frequency domain resource range. This represents the starting resource location within the second frequency domain resource range. The bandwidth size of the second frequency domain resource range / the number of physical resource blocks (PRBs).
