Description

Resource allocation method and device

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a method and an apparatus for resource allocation.

Background

In a New Radio (NR) system, a set of control resources (control resource set, CORESET) is used to transmit a downlink physical control channel (physical downlink control channel, PDCCH). Currently, the protocol specifies how to configure the frequency domain resources belonging to CORESET. Specifically, first, the frequency domain resources of CORESET are allocated according to the granularity of resource block groups (resource block group, RBG), where one RBG includes 6 Resource Blocks (RBs), that is, the frequency domain resources of CORESET include an integer multiple of 6 RBs, for example, CORESET includes 6 RBs or 12 RBs. Second, the RBG allocated to CORESET includes all RBs that are to be located entirely within the bandwidth part (BWP) of CORESET, i.e., the frequency domain resources of COREST are to be located entirely within the BWP of CORESET. Third, the starting RB of the frequency domain resource of CORESET can only be on RBs with an index of an integer multiple of 6.

According to the above method, if there is no whole continuous resource in BWP, the frequency domain resource cannot be configured for CORESET, or the resource near the beginning or end of BWP may not be configured for CORESET, resulting in reduced resource utilization and reduced flexibility of CORESET frequency domain resource configuration.

Detailed Description

Embodiments of the present application are described in detail below with reference to the accompanying drawings.

The embodiments of the present application may be applied to various mobile communication systems, for example: the fifth generation (the 5th generation,5G) New Radio (NR) system in the mobile communication network, long term evolution (long term evolution, LTE) system in the 4G mobile communication network, and other communication systems such as future communication systems, are not limited herein.

In the embodiment of the present application, the interaction between the terminal device and the network device is described as an example, and it should be noted that, the method provided in the embodiment of the present application may be applied not only to the interaction between the terminal device and the network side, but also to the interaction between any two devices, and the embodiment of the present application is not limited to this.

In this embodiment of the present application, the terminal device may be simply referred to as a terminal, which is a device having a wireless transceiver function or a chip that may be disposed in the device. The terminal device may also be referred to as a User Equipment (UE), an access terminal, or the like. In practical applications, the terminal device in the embodiments of the present application may be a mobile phone (mobile phone), a tablet computer (Pad), a computer with a wireless transceiver function, a Virtual Reality (VR) terminal, an augmented reality (augmented reality, AR) terminal, an industrial sensor, a wearable device, an intelligent monitoring terminal, a wireless terminal in industrial control (industrial control), and so on. In the embodiment of the present application, the device for implementing the function of the terminal device may be the terminal device; or a device, such as a chip system, capable of supporting the terminal device to implement the function, which may be installed in the terminal device or used in cooperation with the terminal device.

Network equipment: the wireless access device can be wireless access devices in various systems in a wireless network, and can also be called access network devices. For example, the network device may be a radio access network (radio access network, RAN) node, also referred to as RAN device or base station, that accesses the terminal device to the wireless network. Examples of some network devices are: next generation base stations (gcodeb), transmission reception points (transmission reception point, TRP), evolved Node bs (enbs), radio network controllers (radio network controller, RNC), and the like. In one network architecture, a network device may include a Centralized Unit (CU) node or a Distributed Unit (DU) node, or include a CU node and a DU node. When the network device includes a CU and a DU, a plurality of DUs may be centrally controlled by one CU. In the embodiment of the present application, the means for implementing the function of the network device may be the network device; or may be a device, such as a system-on-a-chip, capable of supporting the network device to perform this function, which may be installed in or used in conjunction with the network device.

Technical terms that may be referred to in this application are first briefly described, and these descriptions of terms are provided by way of example only and are not intended to be limiting.

A symbol may refer to an orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) symbol.

Bandwidth part (BWP): BWP is a continuous segment of resources in the frequency domain. The BWP includes an uplink BWP for uplink transmission and a downlink BWP for downlink transmission, divided according to a transmission direction. The uplink channel or signal transmission is entirely performed in the uplink BWP, and the downlink channel or signal transmission is entirely performed in the downlink BWP. Since the terminal device can only perform data transmission within the BWP range, parameters of the terminal data transmission are mostly configured based on the BWP, such as physical layer parameters, higher layer parameters, and the like.

CORESET, a set of time-frequency resources, is used to transmit downlink PDCCH. CORESET includes in the frequency domainRB, including a succession in the time domain>And a symbol. CORESET is allocated in the frequency domain according to the granularity of RBGs, and one RBG includes 6 RBs, i.e., the frequency domain resource of CORESET includes an integer multiple of 6 RBs, e.g., includes 6 RBs, 12 RBs, etc.

Wherein the resource for transmitting the PDCCH is composed of an aggregation of one or more control channel elements (control channel element, CCEs), the number of CCEs contained in the resource for transmitting the PDCCH is the aggregation level (aggregation level, AL) of this PDCCH. One CCE consists of 6 resource element groups (resource element group, REGs), each REG including one symbol in the time domain, one RB in the frequency domain, and one RB including 12 Resource Elements (REs) in the frequency domain. As shown in fig. 1, a resource diagram included in CORESET is illustrated. CORESET in the figure includes N CCEs, each CCE including 6 REGs.

The network device configures the frequency domain resource of CORESET for the terminal device in a bit map manner, and specifically, the network device can send the frequency domain resource to the terminal deviceA radio resource control (radio resource control, RRC) message including the bitmap is sent, and other parameters of CORESET may be included in the RRC message, such as the number of symbols occupied by CORESET in the time domain, the identity of CORESET, and so on. As shown in fig. 2, the bits in the bit map correspond one-to-one to non-overlapping RBGs, CORESET includes RBGs that start at the first RBG in BWP, and the first (leftmost/most) bit in the bit map corresponds to the first RBG (RBG 0) in BWP. If a bit is set to 1, it indicates that the RBG corresponding to the bit belongs to the frequency domain resource of the CORESET, i.e., the RBG is allocated to the CORESET. In addition, the CRB index of the first Common Resource Block (CRB) of the first RBG in BWP is Wherein (1)>CRB index for the starting frequency domain resource of the BWP, and the bandwidth of the BWP is +.>Consecutive PRBs, < >>Representing an upward rounding. Both RBGs that are entirely outside BWP and RBGs that are not entirely inside BWP (across BWP boundaries) cannot be allocated to CORESET, i.e., RBGs that cannot be entirely contained within the BWP where CORESET resides cannot be allocated to the CORESET. Assuming that RBG 0 to RBG 2 are located in BWP and part of RBs in RBG 3 are located outside BWP in the figure, if RBG 0 to RBG1 are allocated to CORESET, the bit bitmap may be 1100, wherein bits in the bit bitmap correspond to RBG 0 to RBG 3 in sequence from left to right.

As can be seen from the above description, there are many restrictions on RBs allocated to CORESET, which results in that many RBs in BWP cannot be allocated to CORESET, and thus, PDCCH transmitted in CORESET is limited, reducing transmission performance of PDCCH, and reducing resource utilization. For example, for a terminal device with a supported maximum bandwidth of 5MHz, in BWP with a bandwidth of 5MHz and a subcarrier spacing of 30kHz, the number of RBs that can be allocated to CORESET is 6 at maximum, and since the time domain resource of CORESET contains 3 symbols at maximum, the aggregation level of the maximally supportable PDCCH is 2, resulting in poor transmission performance of the PDCCH.

Therefore, the method can improve the flexibility of the frequency domain resource allocation of CORESET, improve the resource utilization rate and improve the transmission performance of PDCCH.

The network architecture and the service scenario described in the embodiments of the present application are for more clearly describing the technical solution of the embodiments of the present application, and do not constitute a limitation on the technical solution provided in the embodiments of the present application, and those skilled in the art can know that, with the evolution of the network architecture and the appearance of the new service scenario, the technical solution provided in the embodiments of the present application is also applicable to similar technical problems.

In this application, the interaction between the network device and the terminal device is taken as an example, and the operation performed by the network device may be performed by a chip or a module inside the network device, and the operation performed by the terminal device may be performed by a chip or a module inside the terminal device.

As shown in fig. 3, a flow chart of a resource allocation method provided in an embodiment of the present application is shown, where the method includes:

s301: the network device determines configuration information.

The configuration information is used for indicating at least one resource block group belonging to a control resource set, wherein each resource block group comprises X resource blocks, and X is a positive integer. For example, X is an integer greater than 0 and less than or equal to 6. For example, X is one of {1,2,3,6 }.

By changing the number of the resource blocks included in each resource block group, the granularity of the frequency domain resource allocation of the control resource set is finer, more resource blocks can be allocated to the frequency domain resource of the control resource set, more time-frequency resources contained in the control resource set can be enabled to support higher PDCCCHAL, and the transmission performance of the PDCCH is improved.

In one implementation, the value of X is predefined or configured by signaling for the network device.

In one implementation, X is equal to the number of resource blocks corresponding to the frequency domain resources of one resource unit group, or X is equal to the number of resource blocks corresponding to the frequency domain resources of one resource unit group set. The set of resource element groups may be referred to as REG bundle.

For example, one resource element group includes one RB in the frequency domain and 1 symbol in the time domain, so the number of resource blocks corresponding to the frequency domain resources of each resource element group may be equal to 1. For example, when CCEs in the PDCCH are mapped to REGs in order of first frequency domain and then time domain, the number of resource blocks corresponding to one set of resource element groups is related to the number of resource element groups included in the set of resource element groups and the number of symbols included in the set of control resources. Illustratively, one set of resource unit groups contains 6 resource unit groups, and the control resource set contains 3 symbols, then one set of resource unit groups corresponds to 2 resource blocks; the control resource set contains 2 symbols, and one resource unit group set corresponds to 3 resource blocks.

In one implementation, the at least one resource block group includes at least one first resource block group, at least one of the X resource blocks included in the first resource block group being located outside of the BWP where the control resource set is located, and the resource blocks (if any) of the X resource blocks other than the at least one resource block being located within the BWP where the control resource set is located.

As for the first resource block group, either a resource block group including an end resource block of BWP, i.e. a resource block group overlapping with the end resource block of BWP, or a resource block group including a start resource block of BWP, i.e. a resource block group overlapping with the start resource block of BWP. A first set of resource blocks may be considered to be the first set of resource blocks within the BWP if the first set of resource blocks comprises the resource block of the starting resource block of the BWP.

In one implementation, the at least one resource block group further includes at least one second resource block group, where X resource blocks included in the second resource block group are all located in the BWP where the control resource set is located.

For example, as shown in fig. 4, RBG 0 and RBG3 are a first resource block group, and RBG 1 and RBG 2 are a second resource block group. 3 RBs in RBG 0 are located outside BWP, and the other 3 RBs are located inside BWP; likewise, 3 RBs in RBG3 are located outside BWP, and the other 3 RBs are located inside BWP. While RBG 1 and RBG 2 include RBs that are both located within BWP.

In addition, when one resource block group includes X resource blocks that are all located outside the BWP where the control resource set is located, the resource block group may or may not be configured to the control resource set, which is not limited in this application.

In one implementation, the common resource block index of the first one of the at least one resource block group isWherein (1)>Common resource block index for the starting resource block of BWP,/->Representing a rounding down.

For example, when x=6, the common resource block index of the first resource block in the first one of the at least one resource block group is

Since the common resource block index of the first resource block group in BWP isLeading to a starting resource block to common resource block index of BWP +.>Cannot be allocated to a control resource set. By the application, the first resource block group configured for controlling the resource setThe common resource block index of the first resource block in (a) is +.>So that the index from the start resource block to the common resource block of BWP is +.>Can be configured to a control resource set, and improves the resource utilization rate.

In yet another implementation, the common resource block index of the first one of the at least one resource block group is, regardless of the value of X

Wherein,common resource block index for the starting resource block of BWP,/->Representing a rounding down.

In this way, when different types of CORESETs coexist, the initial RBs of the different types of CORESETs can only be on RBs with an integral multiple of 6, so that downlink resource fragmentation can be avoided or reduced, and the resource utilization rate can be improved.

The above implementation may be implemented independently of the method flow of fig. 3, i.e. the common resource block index of the first resource block in the first resource block group belonging to the control resource set may be configured as long as the control resource set is configured for the terminal device

In one implementation, a common resource block index of a starting resource block of BWPThe method meets the following conditions:

or (F)>

Wherein,representing the number of resource blocks that BWP comprises, mod represents a modulo operation.

For example, when x=6,the method meets the following conditions:

or (F)>

In yet another implementation, the common resource block index of the starting resource block of BWP regardless of the X valueThe method meets the following conditions:

or (F) >

By means of the implementation mode, when different types of CORESETs coexist, the starting RBs of the different types of CORESETs and the starting RBs or the ending RBs of corresponding BWPs can only be on the RBs with the integral multiple of 6, so that downlink resource fragmentation can be avoided or reduced, and the resource utilization rate is improved.

Wherein the above implementation may be implemented independently of the method flow of fig. 3. The starting resource block satisfying the above formula may be configured for the terminal device whenever the terminal device is configured with BWP.

In one implementation, if the number of resource blocks included in the frequency resource of the control resource set is no longer an integer multiple of 6, and the mapping manner from the control resource unit to the resource unit group in the control resource set is an interleaving mapping, the calculated number of columns of the interleaver may not be an integer, where the interleaver is configured to map the control resource unit in the control resource set to the resource unit group.

For this purpose, the column number C of the interleaver may satisfy the following form:

For example, the interleaver f (x) may satisfy the following form:

wherein x=cr+r; r=0, 1,; c=0, 1,. -%, C-1; n is n _shift The offset value may be configured by the network device or may be a value preset by the protocol.

The above implementation may be implemented independently of the method flow of fig. 3, that is, the above method may be used to determine the number of columns of the interleaver as long as the number of resource blocks included in the frequency resources of the control resource set is not an integer multiple of 6.

In this application, the specific implementation manner of the configuration information is not limited. The configuration information may be, for example, a bit map (bitmap). Each bit in the bit map corresponds to a set of resource blocks. If the value of one bit in the bit map is 1, the resource block group corresponding to the bit belongs to the frequency domain resource of the control resource set; if the value of a bit in the bit map is 0, the resource block group corresponding to the bit does not belong to the frequency domain resource of the control resource set.

For another example, when the configuration information is a bitmap, each bit in the bitmap corresponds to one resource unit group. If the value of one bit in the bit bitmap is 1, the resource block corresponding to the frequency domain resource of the resource unit group corresponding to the bit belongs to the frequency domain resource of the control resource set; if the value of a bit in the bit map is 0, the resource block corresponding to the frequency domain resource of the resource unit group corresponding to the bit does not belong to the frequency domain resource of the control resource set.

For another example, when the configuration information is a bitmap, each bit in the bitmap corresponds to one set of resource unit groups. If the value of one bit in the bit bitmap is 1, the resource block corresponding to the frequency domain resource of the resource unit group set corresponding to the bit belongs to the frequency domain resource of the control resource set; if the value of a bit in the bit bitmap is 0, the resource block corresponding to the frequency domain resource of the resource unit group set corresponding to the bit does not belong to the frequency domain resource of the control resource set.

S302: the network equipment sends configuration information to the terminal equipment; correspondingly, the terminal device receives configuration information from the network device.

Specifically, the network device may send the configuration information through an RRC message, or may send the configuration information through a media access control (media access control, MAC) Control Element (CE), which is not limited in this application.

In a possible implementation, the network device may also not send configuration information, that is to say S302 is an optional step, in which case at least one resource block group belonging to the control resource set may be predefined by the protocol.

S303: and the network equipment sends the physical downlink control channel to the terminal equipment through the control resource set.

In this application, since the network device may allocate resource blocks outside the BWP to the control resource set, and the terminal device only supports communication within the BWP, data transmitted in some resource blocks in the control resource set may not be received by the terminal device. At this time, some resource blocks are valid for the control resource set, some resource blocks are invalid for the control resource set, and the terminal device may receive the PDCCH through the valid resource blocks in the control resource set.

In the present application, the effective resource block of the control resource set refers to a resource block available for transmitting the PDCCH. Alternatively, for a resource block belonging to the control resource set, if the resource block can be used for transmitting the PDCCH, i.e. the resource block is a candidate resource block for transmitting the PDCCH, the resource block is a valid resource block in the control resource set.

Accordingly, the invalid resource block of the control resource set refers to a resource block that is not available for transmitting the PDCCH. Alternatively, for a resource block belonging to the control resource set, if the resource block cannot be used for transmitting the PDCCH, i.e., the resource block is not a candidate resource block for transmitting the PDCCH, the resource block is an invalid resource block in the control resource set.

In a first implementation, for a resource block group belonging to the control resource set, the resource blocks in the resource block group that satisfy the following conditions are valid resource blocks:

the first condition is that the resource block is located in the BWP where the control resource set is located;

and under the second condition, the resource unit group set corresponding to the resource block corresponds to L continuous resource unit groups, L is the number of the resource unit groups corresponding to one resource unit group set, and L is a positive integer.

Among them, the resource blocks satisfying the above conditions in one resource block group belonging to the control resource set may be referred to as resource blocks that can be used for transmitting PDCCH, candidate resource blocks for transmitting PDCCH, or the like. Accordingly, for a resource block group belonging to the control resource set, a resource block in the resource block group that does not satisfy the above condition may also be referred to as a resource block that cannot be used for transmitting the PDCCH, or a non-candidate resource block for transmitting the PDCCH, and so on.

Wherein the set of resource element groups is the minimum granularity in CCE-to-REG mapping in the set of resource controls. The value of L is not limited, and L is equal to 2, 3, 6, or the like, for example. The value of L may be preset by a protocol, or may be configured by a network device, which is not limited in this application.

For example, taking BWP with a bandwidth of 5MHz and a subcarrier spacing of 30kHz as an example, BWP with a bandwidth of 11 RBs and corresponding RB indexes of 0 to 10. If 12 RBs are allocated for the control resource set, the corresponding RB index is 0 to 11. Each of the tiles in fig. 5 and 6 represents one REG, one REG corresponding to one RB in the frequency domain and one symbol in the time domain. When the time domain duration of the control resource set is 3 symbols as shown in fig. 5, if L is configured to be 3, as shown in fig. 5, since an RB having an RB index of 11 in the control resource set is located outside BWP, the RB is an invalid resource block. In the control resource set shown in fig. 5, the RB index of the resource block that can be used for transmitting the PDCCH is 0 to 10, i.e., the RB index of the effective resource block is 0 to 10. Since the RBs corresponding to the resource unit group set are located in the BWP, the control resource set includes 11 resource unit group sets, that is, 3 tiles of each row represent one resource unit group set, and the numbers of the 11 resource unit group sets are set #0 to set #10, respectively.

When the time domain duration of the control resource set is 3 symbols as shown in fig. 6, if L is configured to be 6, the control resource set includes 6 resource unit group sets, i.e., 6 tiles of every two rows represent one resource unit group set, and the numbers of the 6 resource unit group sets are set #0 to set #5, respectively, as shown in fig. 6. Since the RB with the RB index of 11 in the control resource set is located outside the BWP, the RB is an invalid resource block, and thus the resource element group set numbered as set #5 cannot include the RB, resulting in that the resource element group set numbered as set #5 corresponds to only 3 resource element groups. Further, since the number of resource element groups corresponding to the resource element group set numbered as set #5 is smaller than 6, the RB corresponding to the resource element group set numbered as set #5 is an invalid resource block. That is, in the control resource set shown in fig. 6, the RB index of the resource block that can be used for transmitting the PDCCH is 0 to 9, that is, the RB index of the effective resource block is 0 to 9.

In a second implementation, for a resource block group belonging to the control resource set, a resource block in the resource block group satisfying the following condition one is an effective resource block:

in condition one, the resource block is located in the BWP where the control resource set is located.

Among them, a resource block group belonging to the control resource set, which satisfies the above condition one, may be referred to as a resource block that can be used for transmitting PDCCH, a candidate resource block for transmitting PDCCH, or the like. Accordingly, for a resource block group belonging to the control resource set, a resource block in the resource block group that does not satisfy the above condition one may also be referred to as a resource block that cannot be used for transmitting PDCCH, or a non-candidate resource block for transmitting PDCCH, etc.

Correspondingly, for one resource unit set belonging to the control resource set, when the resource unit set corresponds to L continuous resource unit groups, the resource unit set is an effective resource unit set; when the number of the resource unit groups corresponding to the resource unit set is smaller than L, the resource unit set is an invalid resource unit set.

For example, as shown in fig. 6 above, the set of resource element groups numbered set #5 corresponds to only 3 resource element groups, but the RB corresponding to the set of resource element groups is located in BWP, so the RB is an effective resource block, but the set of resource elements is an ineffective set of resource elements.

In this application, in the first implementation manner and the second implementation manner, the network device may transmit the PDCCH in an effective resource block of the control resource set, and the specific process of transmitting the PDCCH is not limited in this application, and is not repeated herein.

In a third implementation, for one resource block group belonging to the control resource set, the resource blocks belonging to the control resource set in the resource block group are valid resource blocks, i.e. each resource block in the resource block group is a valid resource block, whether or not the resource block is located outside the BWP.

In this implementation, each resource block in the resource block group belonging to the control resource set may also be referred to as a resource block that can be used for transmitting the PDCCH, or a candidate resource block for transmitting the PDCCH, or the like.

For example, as shown in fig. 5, the resource block with index 11 is located outside BWP, and also belongs to an effective resource block, i.e., the index of the effective resource block is 0 to 11 in the control resource set shown in fig. 5, i.e., the resource block corresponding to the index of the resource block for transmitting PDCCH is 0 to 11.

In a third implementation manner, the network device may only transmit data corresponding to the PDCCH through the resource blocks located in the BWP in the control resource set, or may transmit data corresponding to the PDCCH through the resource blocks located outside the BWP in the control resource set. For example, Y is an integer greater than 1, and if Y resource blocks are resource blocks for transmitting PDCCH in at least one resource block group belonging to the control resource set, in the case that the Y resource blocks include a resource block located in BWP and a resource block located outside BWP, the network device may transmit data corresponding to PDCCH through the Y resource blocks in any of the following manners.

In one mode, the network device maps data corresponding to the PDCCH to Y resource blocks, and transmits the data mapped to the Y resource blocks.

The network device maps data corresponding to the PDCCH to Y resource blocks, namely the network device performs coding and rate matching on downlink control information borne by the PDCCH according to resources contained in the Y resource blocks, and further maps coding bits obtained after the rate matching to the Y resource blocks according to a certain rule.

In the first aspect, whether the data corresponding to the PDCCH is mapped to a resource block within BWP or to a resource block outside BWP, the network device transmits the data corresponding to the PDCCH mapped to the resource block through the resource block.

The method can be understood that whether the resource block corresponding to the PDCCH is located in BWP or outside BWP, or is located in the channel bandwidth of the terminal device or outside the channel bandwidth of the terminal device, the network device encodes, rate matches, scrambles, modulates, maps the resource and the like according to all the resource blocks corresponding to the PDCCH, and transmits the complete PDCCH, or transmits the data in all the resource blocks corresponding to the PDCCH. The terminal device may receive only data corresponding to the PDCCH in the resource block located in the BWP, and may not receive data corresponding to the PDCCH in the resource located outside the BWP, i.e., the terminal may receive and process the PDCCH in a puncturing manner.

In one implementation, the PDCCH is transmitted repeatedly, i.e., the number of PDCCH transmissions is greater than 1. For each PDCCH retransmission, the network device transmits the complete PDCCH, and although in one PDCCH transmission, the terminal device cannot receive the data corresponding to the PDCCH in the resource block located outside the BWP, for the PDCCH of different retransmission, the terminal device may receive the data corresponding to the PDCCH in a frequency hopping manner, and each time receives different parts of the data corresponding to the PDCCH, so that additional coding gain and frequency diversity gain can be obtained, and the transmission performance of the PDCCH is improved.

In one implementation, downlink control information carried by the PDCCH is scrambled by a public radio network temporary identity (radio network temporary identity, RNTI), where the public RNTI includes at least one of:

paging RNTI, system information RNTI, message 2 RNTI in random access procedure, message B RNTI in random access procedure, temporary cell RNTI.

In the second mode, the network device maps the data corresponding to the PDCCH to Y resource blocks, and transmits the data mapped to the resource blocks located in the BWP in the Y resource blocks.

In the second mode, for a resource block located in BWP, the network device sends data corresponding to PDCCH mapped in the resource block through the resource block; for a resource block located outside BWP, the network device does not send data mapped in the resource block, although mapping data corresponding to PDCCH into the resource block, i.e. performs puncturing processing on the data mapped in the resource block.

The method can be understood that no matter whether the resource block corresponding to the PDCCH is located in the BWP or outside the BWP, or is located in the channel bandwidth of the terminal device or outside the channel bandwidth of the terminal device, the network device performs coding, rate matching, scrambling, modulation, resource mapping and the like according to all the resource blocks corresponding to the PDCCH, but only transmits the PDCCH data corresponding to the resource block located in the BWP, and does not transmit the PDCCH data corresponding to the resource located outside the BWP, that is, the network device adopts a puncturing method to process and transmit the PDCCH. Accordingly, the terminal device also receives only the data corresponding to the PDCCH in the resource block located in the BWP, and does not receive the data corresponding to the PDCCH in the resource located outside the BWP, i.e. the terminal device receives and processes the PDCCH in a puncturing manner.

In one implementation manner, in the second manner, the number of transmissions of the PDCCH is equal to 1, so that resource consumption can be reduced, and resource utilization rate can be improved.

In the application, when the network device adopts the first mode or the second mode and uses the control resource set to transmit the PDCCH, the PDCCH is encoded and rate-matched according to Y resource blocks, that is, when the PDCCH is encoded and rate-matched, the number of corresponding resource blocks is Y.

Accordingly, if the Y resource blocks used for transmitting the PDCCH include resource blocks other than BWP, the terminal device receives data corresponding to the PDCCH only in the resource blocks located within BWP among the Y resource blocks when receiving the PDCCH using the control resource set. The terminal device considers that the network device encodes and rate-matches the PDCCH according to Y resource blocks, instead of the PDCCH according to the resource blocks located within the BWP. Therefore, the terminal device can decode the PDCCH according to the Y resource blocks.

S304: and the terminal equipment receives the physical downlink control channel through the control resource set according to the configuration information.

By the above method, the number of resource blocks included in each resource block group configured by the network device for the control resource set may be less than 6, so that more resource blocks may be configured for the control resource set; in addition, a resource block group comprising resource blocks positioned outside BWP can be configured for the control resource set, so that the flexibility of resource configuration is further improved, and the resource utilization rate is improved.

S701: the network device determines configuration information.

In one implementation, the configuration information is used to indicate a resource block index of a starting resource block of the control resource set and a bandwidth of the control resource set. The resource block index of the initial resource block may be a physical resource block index of the initial resource block; the network device may indicate the bandwidth of the control resource set by indicating the number of resource blocks corresponding to the bandwidth of the control resource set.

In one implementation, the configuration information is used to indicate a resource block index of a starting resource block of the control resource set and a joint coding value of a number of resource blocks corresponding to a bandwidth of the control resource set.

For example, when the resource block index of the starting resource block is the physical resource block index, the indication information is a resource indication value (resource indication value, RIV), and the value of RIV may satisfy the following form:

if it isThen->

If it isThen->

Wherein,to control the size of the BWP (i.e., the number of RBs involved) where the resource set resides, L _RB To control the number of resource blocks corresponding to the bandwidth of the resource set, RBs _start Physical resource block index for the starting resource block of the control resource set.
