Description

Resource allocation method, determination method, device, storage medium and electronic equipment

Technical Field

The disclosure relates to the technical field of communication, and in particular relates to a resource allocation method, a resource allocation device, a storage medium and electronic equipment.

Background

Currently, when a 5G (5 th Generation mobile networks, 5th Generation wireless systems or 5th-Generation, fifth Generation mobile communication technology) NR (New Radio) system is applied to low frequency and medium frequency, the bandwidth of the spectrum resources of the low frequency and the medium frequency is smaller and dispersed, so that the frequency utilization rate is lower. The super frequency fusion technology mainly solves the problem of how to fully utilize spectrum resources when a low frequency or an intermediate frequency has a plurality of small bandwidth carriers with dispersed frequency bands. The super frequency fusion technology breaks the spectrum boundary, so that the uplink spectrums are respectively pooled and flexibly aggregated into a large bandwidth as required, unified scheduling among carriers is realized, and the spectrum efficiency and the user experience are improved.

Currently, in NR, the carrier Bandwidth may be relatively large, and in consideration of power saving of a UE (User Equipment), BWP (Bandwidth Part) is introduced, where the UE uses the BWP as an operating Bandwidth. BWP is a number of PRBs (Physical Resource Block, physical resource blocks) that are contiguous in the frequency domain within one carrier. In one carrier, the base station configures at most four downlink BWP to one UE, but only one active downlink BWP, i.e. only one active BWP for the UE at the same time. Upstream BWP and SUL (Supplementary Uplink, auxiliary upstream) BWP are the same. When resource allocation is performed on multiple carriers, each carrier transmits DCI (Downlink Control Information ) carried by PDCCH (Physical Downlink Control Channel, physical downlink control channel) to schedule resources on the respective carrier, the DCI can only indicate one BWP of one carrier, the domain of frequency domain resource allocation in the DCI can only indicate frequency domain resources in one BWP, and the cost is high due to the need to transmit multiple DCIs for allocating resources on multiple carriers.

Example embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments may be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept 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.

Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus a repetitive description thereof will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities.

Fig. 1 is a flowchart of a method for allocating resources according to an embodiment of the present disclosure, which may be performed by a network side device, as shown in fig. 1, and includes:

step S102: transmitting BWP configuration information of each carrier of the plurality of carriers to the terminal;

the carrier wave may be, for example, a small bandwidth carrier wave of a plurality of frequency bands for frequency fusion. The small bandwidth carriers of the multiple bands for frequency fusion may be configured through RRC (Radio Resource Control ) signaling. For small bandwidth carriers for each frequency band, one or more BWP may be configured. The number of BWP configured by BWP configuration information may be the same or different for the small bandwidth carrier of each frequency band.

Step S104: and transmitting DCI to the terminal, wherein the DCI comprises BWP indication information for indicating a plurality of BWPs positioned on the plurality of carriers.

The DCI may simultaneously indicate a plurality of BWP, which are located on small bandwidth carriers of different frequency bands. It is assumed that there are M small bandwidth carriers for multiple bands where frequency fusion is performed. The BWP indication information in the DCI may simultaneously indicate M BWP located on M carriers. Alternatively, the BWP indication information in the DCI may simultaneously indicate less than M BWP located on M carriers. I.e. for a certain carrier, the DCI may not indicate BWP, indicating that no BWP in the carrier will be activated.

The DCI may not include carrier indication information, such as not including a field for carrier indication. The BWP that has been activated currently is switched to the BWP indicated by the DCI, i.e., a plurality of activated BWP is supported.

Alternatively, the DCI may include carrier indication information for indicating one or more carriers of the M carriers. The carrier indication information includes, for example, M bits, corresponding to M carriers, respectively, where a corresponding bit of 1 indicates that the carrier is an indicated carrier. The carrier indicated by the DCI may be changed to an active carrier. Only the DCI-indicated BWP in the DCI-indicated carrier may be changed to the activated BWP.

According to the resource allocation method of the embodiment of the disclosure, by sending BWP configuration information of each carrier in a plurality of carriers to a terminal and including BWP indication information for indicating a plurality of BWPs located in the plurality of carriers in DCI, PDSCH or PUSCH resources on the plurality of carriers can be scheduled by DCI carried by PDCCH on one carrier, and compared with the resource on each carrier scheduled by DCI carried by PDCCH sent by each carrier, the overhead of DCI can be reduced, occupation of CCE can be reduced, PDCCH collision probability can be reduced, throughput can be improved, UE power consumption can be reduced, and spectral efficiency and user experience can be improved.

In one embodiment of the present disclosure, the BWP configuration information of each carrier of the plurality of carriers may include:

Configuration information of an initial BWP located on each carrier of the plurality of carriers. That is, in the present embodiment, an initial BWP is configured for each of the plurality of carriers.

configuration information of an initial BWP located on one carrier among the plurality of carriers. That is, in the present embodiment, the initial BWP may be configured for only one carrier among the plurality of carriers, and the initial BWP is not configured for the remaining carriers. For the carrier without the initial BWP, no DCI is required to indicate the initial BWP, thereby saving bit overhead of the DCI.

In one embodiment of the present disclosure, the BWP indication information may be used to indicate one BWP located on each of the plurality of carriers. For example, the BWP indication information in DCI may have a plurality of bits, one BWP is indicated for each of the plurality of carriers.

In one embodiment of the present disclosure, the partial value of the bit of BWP indication information represents BWP without an indication of at least one carrier among the plurality of carriers. That is, for at least one carrier of the plurality of carriers, the DCI may not indicate BWP, indicating that no BWP in the carrier is activated. So that dynamic activation and deactivation of the carrier can be achieved. In one embodiment of the present disclosure, the number of bits used for frequency resource allocation by DCI is only determined according to RBGs (Resource Block Group, resource block groups) or PRB numbers of BWP that have been activated, so that bit overhead of DCI can be reduced.

In one embodiment of the present disclosure, the BWP indication information may include a plurality of consecutive bits corresponding to the plurality of carriers, wherein each consecutive bit is used to indicate one BWP of a corresponding one of the carriers, and the number of bits of the consecutive bit is related to the number of BWP configured by BWP configuration information of the corresponding carrier. Optionally, the number of bits of a segment of consecutive bits is related to the initial BWP configured by BWP configuration information of the corresponding carrier and/or the number of other BWP besides the initial BWP. For example, for a carrier configured with initial BWP, the number of bits of the one segment of continuous bits is related to the number of configured initial BWP and the number of non-initial BWP; for carriers where initial BWP is not configured, the number of bits of the one segment of consecutive bits is related to the number of configured non-initial BWP.

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

In one embodiment of the present disclosure, the BWP indication information may include M consecutive bits, each including ceil log ₂ (n _BWP )]Bit per ceil log ₂ (n _BWP )]A number of bits corresponding to one of the plurality of carriers;

If n _BWP，RRC Not greater than X, n _BWP ＝n _BWP,RRC +1，ceil[log ₂ (n _BWP )]The value of each bit is equal to the BWP index which is configured by BWP configuration information of the corresponding carrier and is arranged in sequence;

if n _BWP，RRC Greater than X, n _BWP ＝n _BWP,RRC ，ceil[log ₂ (n _BWP )]The number of bits is used to indicate BWP of the corresponding carrier other than the initial BWP;

wherein M represents the number of the plurality of carriers, n _BWP，RRC The number of BWP other than the initial BWP, which indicates the BWP configuration information configuration of the corresponding carrier, is represented by M, which is a positive integer, and X, which is a positive integer.

For different carriers n _BWP，RRC Can be the same orAre not identical. Illustratively, the BWP indexes, which are arranged in order, may be arranged in ascending order of index values, or may be arranged in descending order of index values. Illustratively, X is 3.

In one example, there is M ceil log in DCI ₂ (n _BWP )]The bits are used for BWP indication. In order of carrier number from small to large (or order from large to small, which is not limiting to the embodiments of the present disclosure, which are only examples herein), per ceil log ₂ (n _BWP )]The bits correspond to one carrier and indicate one BWP within the corresponding one carrier.

When n is _BWP,RRC When 3 or less (an example of X is given above), n _BWP ＝n _BWP,RRC +1，ceil[log ₂ (n _BWP )]The value of the individual bits is equal to the BWP-Id (i.e., the BWP index) of the configuration of the BWP configuration information configuration of the corresponding carrier, which is arranged in ascending order (which is one example of the above-mentioned order); otherwise n _BWP ＝n _BWP,RRC ，ceil[log ₂ (n _BWP )]The bits indicate BWP of the corresponding carrier other than the initial BWP.

if n _BWP，RRC Not greater than X and n for carriers configured with initial BWP _BWP ＝

n _BWP,RRC +1，ceil[log ₂ (n _BWP )]The value of each bit is equal to the BWP index which is configured by BWP configuration information of the corresponding carrier and is arranged in sequence;

if n _BWP，RRC Greater than X, or n for carriers not configured with initial BWP _BWP ＝

n _BWP,RRC ，ceil[log ₂ (n _BWP )]The number of bits is used to indicate the non-initial BWP of the corresponding carrier;

wherein M represents the number of the plurality of carriers, n _BWP，RRC Representing the corresponding carrier waveThe number of BWP other than the initial BWP configured by the BWP configuration information, X is a positive integer.

For different carriers n _BWP，RRC May be the same or different. Illustratively, the BWP indexes, which are arranged in order, may be arranged in ascending order of index values, or may be arranged in descending order of index values. Illustratively, X is 3.

In one example, the initial BWP is configured in only one carrier of the plurality of carriers. In DCI there is M ceil log ₂ (n _BWP )]The bits are used for BWP indication. In order of carrier number from small to large (or order from large to small, which is not limiting to the embodiments of the present disclosure, which are only examples herein), per ceil log ₂ (n _BWP )]The bits correspond to one carrier and indicate one BWP within the corresponding one carrier.

For carriers configured with initial BWP and when n _BWP,RRC Not more than 3 (as an example of X above), n _BWP ＝n _BWP,RRC +1，ceil[log ₂ (n _BWP )]The value of the individual bits is equal to the BWP-Id (i.e., the BWP index) of the configuration of the BWP configuration information configuration of the corresponding carrier, which is arranged in ascending order (which is one example of the above-mentioned order); if n _BWP，RRC Greater than 3, or n for carriers not configured with initial BWP _BWP ＝n _BWP,RRC ，ceil[log ₂ (n _BWP )]The bits indicate BWP of the corresponding carrier other than the initial BWP.

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 plurality of carriers, the BWP indication information including ceil log ₂ [(A*(n _BWP,RRC +1)]]Each bit is used to indicate an initial BWP or a non-initial BWP of the carrier in which the initial BWP is configured, and one BWP of each carrier in which the initial BWP is not configured. Wherein M represents the number of the plurality of carriers.

n _BWP，RRC Represents the number of BWP configuration information configurations of the carriers configured with the initial BWP, except for the initial BWP, and a represents the product of the numbers of BWP configuration information configurations of all the carriers not configured with the initial BWP. For a pair ofThe number of BWP configuration information configured other than the initial BWP may be the same or different in each of the plurality of carriers. Illustratively, for each carrier of the plurality of carriers, the number of BWPs configured by BWP configuration information other than initial BWP is n _BWP，RRC The BWP indication information includes ceil log ₂ [(n _BWP，RRC ) ^M-1 *(n _BWP,RRC +1)]]And a number of bits.

Alternatively, n _BWP，RRC Represents the maximum value of the number of BWP other than the initial BWP of the BWP configuration information configuration of all carriers, and a represents the product of the maximum value of the number of BWP of the BWP configuration information configuration of all carriers without the initial BWP. I.e. the maximum value of the number of BWP other than the initial BWP configured by BWP configuration information of all carriers is n _BWP ， _RRC The BWP indication information includes ceil log ₂ [(n _BWP，RRC ) ^M-1 *(n _BWP,RRC +1)]]Each bit is used to indicate an initial BWP or a non-initial BWP of the carrier in which the initial BWP is configured, and one BWP of each carrier in which the initial BWP is not configured.

In one example, the initial BWP is configured in only one small bandwidth carrier. The number of BWP configuration information configured for each carrier except for the initial BWP is n _BWP ， _RRC In DCI there is ceil log ₂ [(n _BWP，RRC ) ^M-1 *(n _BWP,RRC +1)]]The one bit is used for BWP indication, and the BWP within the plurality of carriers is indicated jointly. There are 3 small bandwidth carriers for multiple bands such as frequency fusion, m=3. Each carrier is configured with 2 BWP (numbered 1, 2), n, in addition to the initial BWP _BWP，RRC =2, the lowest numbered carrier is configured with an initial BWP (numbered 0), and the indication manner can be shown in table 1 below.

In another example, the initial BWP is configured in only one small bandwidth carrier. The maximum number of BWP other than the initial BWP configured by BWP configuration information is n for each carrier _BWP，RRC In DCI there is ceil log ₂ [(n _BWP，RRC ) ^M-1 *(n _BWP,RRC +1)]]The one bit is used for BWP indication, and the BWP within the plurality of carriers is indicated jointly. There are 3 small bandwidth carriers for multiple bands such as frequency fusion, m=3. Each carrier is configured with up to 2 BWP (numbered 1, 2), n, in addition to the initial BWP _BWP，RRC =2, the lowest numbered carrier is configured with an initial BWP (numbered 0), and the indication can be as shown in table 1. If there are less than 2 BWP configured other than the initial BWP for a certain carrier, e.g., no BWP configured with number 1 and/or 2, the DCI values of the BWP not configured are indicated in table 1 to be invalid.

In table 1, the indication method is merely exemplified in the form of a table, and the specific indication method is not limited to the program code or the formula.

The indication manner shown in table 1 above indicates BWP of different carriers jointly, so that the bit overhead of DCI can be further saved.

In one embodiment of the present disclosure, the BWP indication information may include M consecutive bits, each including ceil log ₂ (n _BWP +1)]Bit per ceil log ₂ (n _BWP +1)]A number of bits corresponding to one of the plurality of carriers; if n _BWP，RRC Not greater than X, n _BWP ＝n _BWP,RRC +1，ceil[log ₂ (n _BWP +1)]The value of each bit is equal to the BWP index which is configured by the BWP configuration information of the corresponding carrier and is arranged in sequence, and the value of the existing bit indicates the BWP which is not indicated by the corresponding carrier; if n _BWP，RRC Greater than X, n _BWP ＝n _BWP,RRC ，ceil[log ₂ (n _BWP +1)]The number of bits is used to indicate BWP of the corresponding carrier other than initial BWP, and the presence of the value of the bit indicates that the corresponding carrier is not indicatedBWP shown; wherein M represents the number of the plurality of carriers, n _BWP，RRC X is a positive integer representing the number of BWP other than the initial BWP configured by BWP configuration information of the corresponding carrier.

In one example, there is M ceil log in DCI ₂ (n _BWP +1)]The bits are used for BWP indication.

If there are less than 2 BWP configured other than the initial BWP for a certain carrier, e.g. no BWP configured with number 1 and/or 2, no BWP is indicated in table 2The DCI values of the configured BWP are invalid.

In table 2, the indication method is merely exemplified in the form of a table, and the specific indication method is not limited to the program code or the formula.

The indication manner shown in table 2 above indicates BWP of different carriers jointly, so that the bit overhead of DCI can be further saved.

In one embodiment of the present disclosure, the BWP indicated by the BWP indication information is to be changed to an activated BWP; alternatively, the DCI may include carrier indication information for indicating at least one carrier of the plurality of carriers, and BWP indicated by the BWP indication information located on the indicated carrier is to be changed to active BWP. For example, the carrier indication information includes M bits, corresponding to M carriers, respectively, and a bit of 1 indicates that the carrier is an indicated carrier.

For example, the DCI may include a plurality of domains of frequency domain resource allocation, corresponding to a plurality of BWP already activated in the carrier in an order of increasing carrier numbers, or corresponding to a plurality of BWP indicated by the DCI to be changed to activated. The domain of each frequency domain resource allocation indicates frequency domain resources in the corresponding BWP.

The PRBs in the BWPs are numbered consecutively according to the increasing order of the carrier numbers, and virtual PRBs with consecutive numbers are formed. The DCI indicates the allocated virtual PRBs in the frequency domain resource allocation domain, and the corresponding relation between the virtual PRBs and the actual PRBs in the BWP can learn which BWP of which carrier the allocated PRBs are located. The value of the frequency resource allocation domain in the DCI indicates the number of the allocated initial virtual PRBs and the number of the continuous virtual PRBs. />

For example, resource allocation type 1, n for PUSCH frequency hopping _{UL_hop} The MSB bits are used to indicate the frequency offset of the frequency hopping, which represents the virtual PRB offset before and after the frequency hopping. The remaining bits indicate the allocated virtual PRBs, i.e. the allocated starting virtual resource block and the number of allocated consecutive virtual resource blocks.

For PDSCH resource allocation type 0, the domain of dci frequency domain resource allocation allocates frequency domain resources in a similar manner to PUSCH resource allocation type 0. For PDSCH resource allocation type 1, the manner of domain allocation of frequency domain resources for frequency domain resource allocation in dci is similar to that of PUSCH resource allocation type 1.
