Description

Background Art

[0002] At present, when 5G (5th Generation mobile networks, 5th Generation wireless systems or 5th-Generation) NR (New Radio) systems are used in low-frequency and medium-frequency applications, the frequency utilization rate is low because the bandwidth of low-frequency and medium-frequency spectrum resources is small and scattered. Super frequency fusion technology mainly solves the problem of how to make full use of spectrum resources when there are multiple small-bandwidth carriers in scattered frequency bands in low-frequency or medium-frequency bands. Super frequency fusion technology breaks the spectrum boundaries, allowing the uplink spectrum to be pooled separately and flexibly aggregated into large bandwidths on demand, realizing unified scheduling between carriers, and improving spectrum efficiency and user experience.

[0003] At present, in NR, the carrier bandwidth may be relatively large. Considering the power saving factor of UE (User Equipment), BWP (Bandwidth Part) is introduced, and UE uses BWP as the working bandwidth. BWP is a number of continuous PRBs (Physical Resource Blocks) in the frequency domain within a carrier. In one carrier, the base station configures a UE with up to four downlink BWPs, but there is only one activated downlink BWP, that is, the UE has only one working BWP at the same time. The uplink BWP and SUL (Supplementary Uplink) BWP are the same. When allocating resources on multiple carriers, each carrier sends DCI (Downlink Control Information) carried by PDCCH (Physical Downlink Control Channel) to schedule the resources on its own carrier. DCI can only indicate one BWP of one carrier, and the frequency domain resource allocation domain in DCI can only indicate the frequency domain resources in one BWP. Allocating resources on multiple carriers requires sending multiple DCIs, resulting in high overhead. Summary of the invention

[0038] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that the disclosure will be more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0039] In addition, the accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and their repeated description will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0040] Figure 1 is a flow chart of a resource allocation method according to an embodiment of the present disclosure, which method may be executed by a network side device, such as Figure 1 As shown, the method includes:

[0041] Step S102: Sending BWP configuration information of each carrier among multiple carriers to the terminal;

[0042] Among them, the carrier may be, for example, a small bandwidth carrier of multiple frequency bands for frequency fusion. The small bandwidth carrier of multiple frequency bands for frequency fusion may be configured through RRC (Radio Resource Control) signaling. For each frequency band's small bandwidth carrier, one or more BWPs may be configured. For each frequency band's small bandwidth carrier, the number of BWPs configured by the BWP configuration information may be the same or different.

[0043] Step S104: Send DCI to the terminal, wherein the DCI includes BWP indication information for indicating a plurality of BWPs located on the plurality of carriers.

[0044] DCI can indicate multiple BWPs at the same time, and multiple BWPs are located in small bandwidth carriers of different frequency bands. Assume that there are M small bandwidth carriers of multiple frequency bands for frequency fusion. The BWP indication information in DCI can simultaneously indicate M BWPs located on M carriers. Alternatively, the BWP indication information in DCI can simultaneously indicate less than M BWPs located on M carriers. That is, for a certain carrier, DCI may not indicate BWP, indicating that no BWP in the carrier will be activated.

[0045] The DCI may not include carrier indication information, such as not including a field for carrier indication. The currently activated BWP will switch to the BWP indicated by the DCI, that is, multiple activated BWPs are supported.

[0046] Alternatively, the DCI may include carrier indication information for indicating one or more carriers among the M carriers. The carrier indication information may include, for example, M bits, corresponding to the M carriers respectively, and a corresponding bit being 1 indicates that the carrier is the indicated carrier. The carrier indicated by the DCI will be changed to an activated carrier. Only the BWP indicated by the DCI in the carrier indicated by the DCI will be changed to an activated BWP.

[0047] A resource allocation method according to an embodiment of the present invention sends BWP configuration information of each carrier among multiple carriers to a terminal, and includes BWP indication information for indicating multiple BWPs located on multiple carriers in DCI, so that DCI carried by PDCCH on one carrier can be used to schedule PDSCH or PUSCH resources on multiple carriers. Compared with each carrier sending DCI carried by PDCCH to schedule resources on its own carrier, this method can reduce DCI overhead, reduce CCE occupancy, reduce PDCCH collision probability, improve throughput, reduce UE power consumption, and improve spectrum efficiency and user experience.

[0048] In one embodiment of the present disclosure, the BWP configuration information of each carrier in the multiple carriers may include:

[0049] Configuration information of an initial BWP, where the initial BWP is located in each of the multiple carriers. That is, in this embodiment, an initial BWP is configured for each of the multiple carriers.

[0050] In one embodiment of the present disclosure, the BWP configuration information of each carrier in the multiple carriers may include:

[0051] Configuration information of the initial BWP, where the initial BWP is located in one of the multiple carriers. That is, in this embodiment, only one of the multiple carriers may be configured with the initial BWP, and the remaining carriers may not be configured with the initial BWP. For the carrier that is not configured with the initial BWP, the DCI does not need to indicate the initial BWP, thereby saving the bit overhead of the DCI.

[0052] In one embodiment of the present disclosure, the BWP indication information may be used to indicate a BWP located in each of the multiple carriers. For example, the BWP indication information in the DCI may have multiple bits, indicating a BWP for each of the multiple carriers.

[0053] In one embodiment of the present disclosure, some values ​​of the bits of the BWP indication information indicate that there is no indicated BWP located in at least one of the multiple carriers. That is, for at least one carrier among the multiple carriers, the DCI may not indicate the BWP, indicating that no BWP in the carrier will be activated. Thus, dynamic activation and deactivation of carriers can be achieved. In one embodiment of the present disclosure, the number of bits used by the DCI for frequency resource allocation only needs to be determined based on the RBG (Resource Block Group) or PRB number of the activated BWP, thereby reducing the bit overhead of the DCI.

[0054] In one embodiment of the present disclosure, the BWP indication information may include multiple segments of continuous bits corresponding to the multiple carriers, wherein each segment of continuous bits is used to indicate a BWP of a corresponding carrier, and the number of bits of the segment of continuous bits is related to the number of BWPs configured by the BWP configuration information of the corresponding carrier. Optionally, the number of bits of a segment of continuous bits is related to the initial BWP and / or the number of other BWPs other than the initial BWP configured by the BWP configuration information of the corresponding carrier. For example, for a carrier configured with an initial BWP, the number of bits of the above segment of continuous bits is related to the number of configured initial BWPs and the number of non-initial BWPs; for a carrier not configured with an initial BWP, the number of bits of the above segment of continuous bits is related to the number of configured non-initial BWPs.

[0055] In one embodiment of the present disclosure, each bit of the BWP indication information is used to indicate a plurality of BWPs located on the plurality of carriers.

[0056] In one embodiment of the present disclosure, the BWP indication information may include M segments of continuous bits, each segment of continuous bits including ceil[log2(n BWP )] bits, every ceil[log2(n BWP )] bits correspond to one carrier among the plurality of carriers;

[0057] If BWP，RRC Not greater than X, n BWP =n BWP,RRC +1, ceil[log2(n BWP )] bits have a value equal to the BWP index arranged in order configured by the BWP configuration information of the corresponding carrier;

[0058] If BWP，RRC Greater than X, n BWP =n BWP,RRC , ceil[log2(n BWP )] bits are used to indicate the BWP of the corresponding carrier other than the initial BWP;

[0059] Wherein, M represents the number of the plurality of carriers, n BWP，RRC It represents the number of BWPs other than the initial BWP configured by the BWP configuration information of the corresponding carrier, M is a positive integer, and X is a positive integer.

[0060] For different carriers, n BWP，RRC They may be the same or different. For example, the BWP indexes arranged in sequence may be arranged in ascending order of index values ​​or in descending order of index values. For example, X is 3.

[0061] In one example, DCI has M*ceil[log2(n BWP )] bits are used for BWP indication. According to the order of carrier numbers from small to large (or from large to small, the embodiment of the present disclosure is not limited to this, this is just an example), every ceil[log2(n BWP )] bit corresponds to a carrier, indicating a BWP within the corresponding carrier.

[0062] When n BWP,RRC When n is less than or equal to 3 (an example of X above), BWP =n BWP,RRC +1, ceil[log2(n BWP )] bits have a value equal to the BWP-Id (i.e., the above-mentioned BWP index) configured in ascending order (an example of the above-mentioned order arrangement) of the BWP configuration information of the corresponding carrier; otherwise n BWP =n BWP,RRC , ceil[log2(n BWP )] bits indicate the BWP of the corresponding carrier other than the initial BWP.

[0063] In one embodiment of the present disclosure, the BWP indication information may include M segments of continuous bits, each segment of continuous bits including ceil[log2(n BWP )] bits, every ceil[log2(n BWP )] bits correspond to one carrier among the plurality of carriers;

[0064] If BWP，RRC Not greater than X and for carriers configured with initial BWP, n BWP =

[0065] n BWP,RRC +1, ceil[log2(n BWP )] bits have a value equal to the BWP index arranged in order configured by the BWP configuration information of the corresponding carrier;

[0066] If BWP，RRCGreater than X, or for carriers without an initial BWP, n BWP =

[0067] n BWP,RRC , ceil[log2(n BWP )] bits are used to indicate the non-initial BWP of the corresponding carrier;

[0068] Wherein, M represents the number of the plurality of carriers, n BWP，RRC It represents the number of BWPs other than the initial BWP configured by the BWP configuration information of the corresponding carrier, and X is a positive integer.

[0069] For different carriers, n BWP，RRC They may be the same or different. For example, the BWP indexes arranged in sequence may be arranged in ascending order of index values ​​or in descending order of index values. For example, X is 3.

[0070] In one example, the initial BWP is configured in only one of the multiple carriers. BWP )] bits are used for BWP indication. According to the order of carrier numbers from small to large (or from large to small, the embodiment of the present disclosure is not limited to this, this is just an example), every ceil[log2(n BWP )] bit corresponds to a carrier, indicating a BWP within the corresponding carrier.

[0071] For a carrier with an initial BWP configured and when n BWP,RRC When n is not greater than 3 (an example of X above), BWP =n BWP,RRC +1, ceil[log2(n BWP )] bits have a value equal to the BWP-Id (i.e., the above-mentioned BWP index) configured in ascending order (an example of the above-mentioned order arrangement) of the BWP configuration information of the corresponding carrier; if n BWP，RRC Greater than 3, or for carriers without an initial BWP, n BWP =n BWP,RRC , ceil[log2(n BWP )] bits indicate the BWP of the corresponding carrier other than the initial BWP.

[0072] In one embodiment of the present disclosure, there may be a carrier configured with an initial BWP and a carrier not configured with an initial BWP among the multiple carriers, and the BWP indication information includes ceil[log2[(A*(n BWP,RRC+1)]] bits, each bit is used to indicate the initial BWP or non-initial BWP of the carrier configured with the initial BWP, and one BWP for each carrier not configured with the initial BWP. Wherein, M represents the number of the multiple carriers.

[0073] n BWP，RRC represents the number of BWPs other than the initial BWP configured by the BWP configuration information of the carrier configured with the initial BWP, and A represents the product of the number of BWPs configured by the BWP configuration information of all carriers not configured with the initial BWP. For each of the multiple carriers, the number of BWPs other than the initial BWP configured by the BWP configuration information may be the same or different. Exemplarily, for each of the multiple carriers, the number of BWPs other than the initial BWP configured by the BWP configuration information is n. BWP，RRC The BWP indication information includes ceil[log2[(n BWP，RRC ) M-1 *(n BWP,RRC +1)]] bits.

[0074] Or, BWP，RRC Indicates the maximum number of BWPs configured by the BWP configuration information of all carriers except the initial BWP, and A indicates the product of the maximum number of BWPs configured by the BWP configuration information of all carriers that are not configured with the initial BWP. That is, the maximum number of BWPs configured by the BWP configuration information of all carriers except the initial BWP is n. BWP , RRC The BWP indication information includes ceil[log2[(n BWP，RRC ) M-1 *(n BWP,RRC +1)]] bits, each bit is used to indicate the initial BWP or non-initial BWP of a carrier configured with an initial BWP, and a BWP for each carrier not configured with an initial BWP.

[0075] In one example, the initial BWP is configured in only one small bandwidth carrier. For each carrier, the number of BWPs configured by the BWP configuration information except the initial BWP is n. BWP , RRC , DCI has ceil[log2[(n BWP，RRC ) M-1 *(n BWP,RRC +1)]] bits are used for BWP indication, which jointly indicates the BWP in multiple carriers. For example, there are 3 small bandwidth carriers in multiple frequency bands of frequency fusion, M = 3. In addition to the initial BWP, each carrier is configured with 2 BWPs (numbered 1, 2), n BWP，RRC=2, the carrier with the smallest number is configured with the initial BWP (number 0), and the indication method can be shown in the following Table 1.

[0076] Table 1

[0077]

[0078]

[0079] In another example, the initial BWP is configured in only one small bandwidth carrier. For each carrier, the maximum number of BWPs configured by the BWP configuration information except the initial BWP is n. BWP，RRC , DCI has ceil[log2[(n BWP，RRC ) M-1 *(n BWP,RRC +1)]] bits are used for BWP indication, which jointly indicates the BWP in multiple carriers. For example, there are 3 small bandwidth carriers in multiple frequency bands of frequency fusion, M = 3. Each carrier is configured with a maximum of 2 BWPs (numbered 1, 2) in addition to the initial BWP, n BWP，RRC =2, the carrier with the smallest number is configured with the initial BWP (number 0), and the indication method may be as shown in Table 1. If less than 2 BWPs are configured for a carrier in addition to the initial BWP, such as no BWPs numbered 1 and / or 2 are configured, the DCI value indicating the unconfigured BWP in Table 1 is invalid.

[0080] It should be noted that in the above Table 1, the indication method is only exemplified in the form of a table, and the specific indication method is not limited to program code or formula.

[0081] The indication method shown in Table 1 above performs joint indication for the BWP of different carriers, which can further save the bit overhead of DCI.

[0082] In one embodiment of the present disclosure, the BWP indication information may include M segments of continuous bits, each segment of continuous bits including ceil[log2(n BWP +1)] bits, every ceil[log2(n BWP +1)] bits correspond to one of the multiple carriers; if n BWP，RRC Not greater than X, n BWP =n BWP,RRC +1, ceil[log2(n BWP +1)] bits have a value equal to the BWP index in the order configured by the BWP configuration information of the corresponding carrier, and the value of the bit indicates that the corresponding carrier has no indicated BWP; if n BWP，RRC Greater than X, n BWP =n BWP,RRC, ceil[log2(n BWP +1)] bits are used to indicate the BWP of the corresponding carrier other than the initial BWP, and the existence of the value of the bit indicates that the corresponding carrier has no indicated BWP; wherein M represents the number of the multiple carriers, n BWP，RRC It represents the number of BWPs other than the initial BWP configured by the BWP configuration information of the corresponding carrier, and X is a positive integer.

[0083] For different carriers, n BWP，RRC They may be the same or different. For example, the BWP indexes arranged in sequence may be arranged in ascending order of index values ​​or in descending order of index values. For example, X is 3.

[0084] In one example, DCI has M*ceil[log2(n BWP +1)] bits are used for BWP indication. According to the order of carrier numbers from small to large (or from large to small, the embodiment of the present disclosure is not limited to this, this is just an example), every ceil[log2(n BWP +1)] bit corresponds to a carrier, indicating a BWP in the corresponding carrier, or the indicated BWP is null. The BWP indicated in the embodiment of the present disclosure is null, that is, the BWP of the corresponding carrier is not indicated, indicating that the corresponding carrier has no indicated BWP, and no BWP in the carrier will be activated. BWP,RRC When n is less than or equal to 3, BWP =n BWP,RRC +1, ceil[log2(n BWP +1)] bits have a value equal to the BWP-Id (i.e., the BWP index) configured in ascending order according to the BWP configuration information of the corresponding carrier. The maximum value of the bit (an example of the value of the bit with the BWP indication information) indicates that the indicated BWP is null; otherwise, n BWP =n BWP,RRC , ceil[log2(n BWP +1)] bits indicate the BWP of the corresponding carrier other than the initial BWP, wherein a value of the pre-set bit indicates that the indicated BWP is null.

[0085] In one embodiment of the present disclosure, the BWP indication information may include M segments of continuous bits, each segment of continuous bits including ceil[log2(n BWP +1)] bits, every ceil[log2(n BWP +1)] bits correspond to one carrier among the plurality of carriers;

[0086] If BWP，RRCNot greater than X and for carriers configured with initial BWP, n BWP =n BWP,RRC +1, ceil[log2(n BWP +1)] bits have a value equal to the BWP index arranged in order configured by the BWP configuration information of the corresponding carrier, and the presence of the bit value indicates that the corresponding carrier has no indicated BWP;

[0087] If BWP，RRC Greater than X, or for carriers without an initial BWP, n BWP =n BWP,RRC , ceil[log2(n BWP +1)] bits are used to indicate the non-initial BWP of the corresponding carrier, and the presence of the value of the bit indicates that the corresponding carrier has no indicated BWP;

[0088] Wherein, M represents the number of the plurality of carriers, n BWP，RRC It represents the number of BWPs other than the initial BWP configured by the BWP configuration information of the corresponding carrier, and X is a positive integer.

[0089] For different carriers, n BWP，RRC They may be the same or different. For example, the BWP indexes arranged in sequence may be arranged in ascending order of index values ​​or in descending order of index values. For example, X is 3.

[0090] In one example, the initial BWP is configured in only one small bandwidth carrier. In DCI, there is M*ceil[log2(n BWP +1)] bits are used for BWP indication. According to the order of carrier numbers from small to large (or from large to small, the embodiment of the present disclosure is not limited to this, this is just an example), every ceil[log2(n BWP +1)] bit corresponds to a carrier, indicating a BWP in the corresponding carrier, or the indicated BWP is null. For a carrier with an initial BWP configured and when n BWP,RRC When n is not greater than 3, BWP =n BWP,RRC +1, ceil[log2(n BWP +1)] bits have a value equal to the BWP-Id (i.e., the BWP index) configured in ascending order according to the BWP configuration information of the corresponding carrier. The maximum value of the bit (an example of the value of the bit with the BWP indication information) indicates that the indicated BWP is null; otherwise, n BWP =n BWP,RRC , ceil[log2(n BWP+1)] bits indicate the BWP of the corresponding carrier other than the initial BWP, wherein a value of the pre-set bit indicates that the indicated BWP is null.

[0091] In one embodiment of the present disclosure, there may be a carrier configured with an initial BWP and a carrier not configured with an initial BWP among the multiple carriers, and the BWP indication information includes ceil[log2[B*(n BWP,RRC +2)]] bits, each bit is used to indicate an initial BWP or non-initial BWP of a carrier configured with an initial BWP, or indicates that a BWP is not indicated for a carrier configured with an initial BWP, and each bit is used to indicate a BWP of a carrier not configured with an initial BWP, or indicates that a BWP is not indicated for a carrier not configured with an initial BWP, wherein M represents the number of the multiple carriers.

[0092] n BWP，RRC represents the number of BWPs other than the initial BWP configured by the BWP configuration information of the carrier configured with the initial BWP, and B represents the product of the number of BWPs configured by the BWP configuration information of all carriers not configured with the initial BWP plus 1. For each of the multiple carriers, the number of BWPs other than the initial BWP configured by the BWP configuration information may be the same or different. Exemplarily, for each of the multiple carriers, the number of BWPs other than the initial BWP configured by the BWP configuration information is n. BWP，RRC The BWP indication information includes ceil[log2[(n BWP，RRC +1) M-1 *(n BWP,RRC +2)]] bits.

[0093] Or, BWP，RRC Indicates the maximum number of BWPs configured by the BWP configuration information of all carriers except the initial BWP, and B indicates the product of the maximum number of BWPs configured by the BWP configuration information of all carriers that are not configured with the initial BWP plus 1. That is, the maximum number of BWPs configured by the BWP configuration information of all carriers except the initial BWP is n. BWP，RRC The BWP indication information includes ceil[log2[(n BWP，RRC +1) M-1 *(n BWP,RRC +2)]] bits, each bit is used to indicate the initial BWP or non-initial BWP of a carrier configured with an initial BWP, or indicates that a carrier configured with an initial BWP has no indicated BWP, and each bit is used to indicate a BWP of a carrier not configured with an initial BWP, or indicates that a carrier not configured with an initial BWP has no indicated BWP.

[0094] In one example, a small bandwidth carrier is used as an example, and an initial BWP is configured in only one small bandwidth carrier. For each carrier, the number of BWPs configured by the BWP configuration information except the initial BWP is n. BWP，RRC , DCI has ceil[log2[(n BWP , RRC +1) M-1 *(n BWP,RRC +2)]] bits are used for BWP indication. Jointly indicate BWP in multiple carriers. BWP indication for a carrier can be null, that is, no BWP is indicated, indicating that no BWP in the carrier will be activated. For example, there are 3 small bandwidth carriers in multiple frequency bands of frequency fusion, M = 3. Each carrier is configured with 2 BWPs (numbered 1, 2) in addition to the initial BWP, n BWP , RRC =2, the carrier with the smallest number is configured with the initial BWP (number 0), and the indication method is shown in the following Table 2.

[0095] Table 2

[0096]

[0097]

[0098] In another example, the initial BWP is configured in only one small bandwidth carrier. For each carrier, the maximum number of BWPs configured by the BWP configuration information except the initial BWP is n. BWP，RRC , DCI has ceil[log2[(n BWP，RRC +1) M-1 *(n BWP,RRC +2)]] bits are used for BWP indication, which jointly indicates the BWP in multiple carriers. The BWP indication for a carrier can be null, that is, no BWP is indicated, indicating that no BWP in the carrier will be activated. For example, there are 3 small bandwidth carriers in multiple frequency bands of frequency fusion, M = 3. Each carrier can be configured with up to 2 BWPs (numbered 1, 2) in addition to the initial BWP, n BWP，RRC =2, the carrier with the smallest number is configured with the initial BWP (number 0), and the indication method may be as shown in Table 2. If less than 2 BWPs are configured for a carrier in addition to the initial BWP, such as no BWPs numbered 1 and / or 2 are configured, then the DCI value indicating the unconfigured BWP in Table 2 is invalid.

[0099] It should be noted that in the above Table 2, the indication method is only exemplified in the form of a table, and the specific indication method is not limited to program code or formula.

[0100] The indication method shown in Table 2 above performs joint indication for the BWP of different carriers, which can further save the bit overhead of DCI.

[0101] In one embodiment of the present disclosure, the BWP indicated by the BWP indication information will be changed to an activated BWP; or, the DCI may include carrier indication information, the carrier indication information is used to indicate at least one carrier among the multiple carriers, and the BWP indicated by the BWP indication information located in the indicated carrier will be changed to an activated BWP. For example, the carrier indication information includes M bits, corresponding to M carriers respectively, and accordingly, a bit of 1 indicates that the carrier is the indicated carrier. Thus, dynamic activation and deactivation of the carrier can be achieved.

[0102] In one embodiment of the present disclosure, the DCI may further include frequency domain resource allocation information, where the frequency domain resource allocation information is used to indicate frequency domain resources in a plurality of BWPs.

[0103] In one embodiment of the present disclosure, the frequency domain resources in the multiple BWPs indicated by the frequency domain resource allocation information may be the frequency domain resources in the multiple BWPs that are currently activated, or may also be the frequency domain resources in the multiple BWPs that are to be changed to activated as indicated by the DCI.

[0104] In one embodiment of the present disclosure, the frequency domain resource allocation information may include multiple segments of continuous bits corresponding to multiple BWPs, wherein each segment of continuous bits is used to indicate the frequency domain resources in a corresponding BWP, and the number of bits in the segment of continuous bits is related to the number of resource block groups RBGs or resource blocks included in the corresponding BWP, or is related to the corresponding BWP size. For example, the DCI may include multiple frequency domain resource allocation domains, corresponding to multiple BWPs that have been activated in the carrier in ascending order of carrier numbers, or corresponding to multiple BWPs that will be changed to activated as indicated by the DCI. Each frequency domain resource allocation domain indicates the frequency domain resources in the corresponding BWP.

[0105] Alternatively, each bit included in the frequency domain resource allocation information is used to indicate the frequency domain resources in multiple BWPs. The frequency domain resource allocation field in the DCI jointly indicates the frequency domain resources in multiple BWPs, which can save the bit overhead of the DCI.

[0106] In one embodiment of the present disclosure, the frequency domain resource allocation information may include N RBG,mulXLBWP bits, each bit corresponds to an RBG (Resource Block Group) and is used to indicate whether the corresponding RBG is allocated. RBG,mulXLBWPIndicates the total number of RBGs in multiple BWPs. Each RBG includes resource blocks located in one BWP, or there are RBGs that include resource blocks located in more than one BWP. For example, for PUSCH resource allocation type 0, the frequency domain resource allocation field in DCI uses N RBG,mulULBWP bits indicate the frequency domain resources in multiple UL (Uplink) BWPs, N RBG,mulULBWP is the total number of resource block groups in multiple UL BWPs. The RBGs in multiple UL BWPs may be arranged, for example, in the following order: the RBGs in the BWP in each carrier are arranged in ascending order of frequency, and the RBGs of different carriers are arranged in ascending order of carrier numbers, corresponding to each bit in the frequency domain resource allocation domain from MSB (Most Significant Bit) to LSB (Least Significant Bit). For example, a bit value of 1 may be used to indicate that the corresponding RBG is allocated.

[0107] or,

[0108] The frequency domain resource allocation information includes bits, used to indicate the starting virtual resource block allocated and the number of consecutive virtual resource blocks allocated, the allocated virtual resource blocks are mapped to resource blocks in multiple BWPs, where: Indicates the total number of resource blocks included in multiple BWPs. For example, for PUSCH resource allocation type 1, the frequency domain resource allocation domain in DCI adopts bits indicate the frequency domain resources in multiple ULBWPs, Indicates the total number of PRBs in multiple UL BWPs. In the order of increasing carrier numbers, the PRBs in multiple BWPs are numbered consecutively to form consecutively numbered virtual PRBs. The frequency domain resource allocation field in the DCI indicates the allocated virtual PRBs. According to the correspondence between the virtual PRBs and the actual PRBs in the BWP, it can be known which BWP of which carrier the allocated PRBs are located in. The value of the frequency domain resource allocation field in the DCI indicates the allocated starting virtual PRB and the number of the consecutive virtual PRBs.

[0109] Or,

[0110] The frequency domain resource allocation information includes bits, where N hop The bit is used to indicate the frequency offset of the frequency hopping, and the remaining bits are used to indicate the starting virtual resource block allocated and the number of consecutive virtual resource blocks allocated. The allocated virtual resource blocks are mapped to resource blocks in multiple BWPs. hop It can be determined based on the number of frequency offsets of the frequency hopping configured in the high-level signaling. Indicates the total number of resource blocks included in multiple BWPs.

[0111] For example, for PUSCH frequency hopping resource allocation type 1, N UL_hop The first MSB bits are used to indicate the frequency offset of the frequency hopping, which indicates the virtual PRB offset before and after the frequency hopping. The remaining bits indicate the allocated virtual PRB, that is, the allocated starting virtual resource block and the number of allocated continuous virtual resource blocks.

[0112] For PDSCH resource allocation type 0, the frequency domain resource allocation method in the DCI is similar to that of PUSCH resource allocation type 0. For PDSCH resource allocation type 1, the frequency domain resource allocation method in the DCI is similar to that of PUSCH resource allocation type 1. They will not be described one by one here.
