Description

Resource adjustment method and equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for adjusting resources.

Background

In future communication systems, unlicensed bands (unlicensed bands) may be used as a complement to licensed bands (licensed bands) to help operators expand services.

In the prior art, when the 5G communication system operates in an unlicensed frequency band, downlink broadband transmission may be performed, and when downlink bandwidth transmission is performed, listen-before-talk (Listen Before Talk, LBT) listening is generally performed on the unlicensed frequency band, where a bandwidth portion (BWP) of the operation has a width greater than a width (20 MHz) of an LBT subband (subband). On running BWP, the base station may transmit on all or part of the subbands where LBT interception is successful. However, when the base station listens successfully only on a part of the subbands, the addition of a guard band needs to be considered at the edge of the successfully intercepted subbands to meet the requirement of interference leakage of the adjacent subbands. For example, LBT interception is performed in 4 consecutive subbands (subband 1, subband2, subband3, and subband4, respectively), and when the interception of subband2 and subband3 is successful, the portion of subband2 adjacent to subband 1 and the portion of subband3 adjacent to subband4 need to be protected from interference on subbands 1 and2, while on subbands 2 and3, due to the successful interception, no guard band needs to be left between subbands 2 and 3.

However, when the base station configures the terminal device with the control resource set (Control Resource Set, CORESET), the interception result of LBT is uncertain. Therefore, in order to avoid interference, the base station reserves guard bands when configuring CORESET on each subband in the running BWP, so that those unnecessary guard bands may cause resource waste.

Detailed Description

The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Some terms involved in the present invention are explained below for convenience of the reader to understand:

1. control resource set in NR Rel15 (Control Resource Set, CORESET)

CORESET is a set of time-frequency resources introduced in NR, that is, a User Equipment (UE) performs detection of a downlink control channel (Physical Downlink Control Channel, PDCCH) at the corresponding CORESET.

Specific: in the control region of one slot, there are one or more CORESETs at which the UE can detect the PDCCH. The NR PDCCH is transmitted using one or more (e.g., 1, 2, 4, 8) control channel elements (Control Channel Elements, CCE), i.e., the mapping of the NR PDCCH to time-frequency resources is based on the CCE structure, the basic resource units constituting the CCE are resource element groups (Resource Element Group, REGs), one CCE is composed of a certain number of REGs (e.g., 6 REGs), i.e., CORESET is composed of a set of REGs. One REG consists of one RB in the frequency domain (i.e., 12 consecutive subcarriers) and one orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbol in the time domain.

In NR Rel15, the time-frequency location configuration of CORESET is signaled by higher layer signaling. The frequency domain position of CORESET is configured by the parameter frequencydomain resources, which is a 45 bit map, each bit representing 6 consecutive RBs, the first bit from the left representing the first RB group configuring BWP. For RB groups beyond the configured BWP frequency domain, its corresponding bit needs to be set to 0.

2. Search Space (Search Space) configuration in NR Rel15

In the LTE system, the PDCCH occupies the entire frequency band in the frequency domain, and occupies the first 1 to 3 OFDM symbols of each subframe in the time domain, that is, the system only needs to inform the UE of the number of OFDM symbols occupied by the PDCCH, so that the UE can determine the search space of the PDCCH.

In the NR system, since the bandwidth of the system (the maximum bandwidth may be 400 MHz) is large, if the PDCCH still occupies the whole bandwidth, not only resources are wasted, but also blind detection complexity is large. In addition, in order to increase system flexibility, the starting position of the PDCCH in the time domain may also be configured. That is, in the NR system, the UE knows the position of the PDCCH in the frequency domain and the position of the PDCCH in the time domain to successfully decode the PDCCH. For convenience, the NR system encapsulates information such as the frequency band occupied on the PDCCH frequency domain or the number of OFDM symbols occupied on the time domain in CORESET, and encapsulates information such as the PDCCH start OFDM symbol number and the PDCCH monitoring period in the Search Space. One CORESET needs to be associated for each Search Space, and then the user performs PDCCH monitoring based on the Search Space.

3. Interception-then-session (Listen Before Talk, LBT) interception

When the 5G communication system operates in an unlicensed frequency band, before transmitting information, the UE or the network device needs to perform channel idle estimation (Clear Channel Assess, CCA)/extended channel idle estimation (extended Clear Channel Assess, eCCA) to listen to the channel, i.e. perform Energy Detection (ED), and when the Energy is below a certain threshold, the channel is determined to be empty, and the UE or the network device can start transmission. This contention-based access approach leads to uncertainty in the time available for the channel, since the unlicensed band is shared by multiple technologies or multiple transmission nodes.

4. Sub-band (subband)

The 5G communication system may perform downlink wideband transmission when operating in an unlicensed frequency band, i.e., the operating BWP bandwidth is greater than the sub-bandwidth of the LBT (20 MHz). On running BWP, the base station may transmit on all or part of the LBT subbands where LBT is successful. However, when the LBT is successful on only a part of the subbands, the addition of a guard band needs to be considered at the edge of the successful LBT subband to meet the requirement of interference leakage to the adjacent subbands. For example, the running BWP includes 4 consecutive LBT subbands, which are respectively subband 1, subband2, subband3 and subband4, and the base station performs LBT interception on these 4 LBT subbands, where when the LBT of subband2 and subband3 is successful, the portion of subband2 adjacent to subband 1 and the portion of subband3 adjacent to subband4 need to be reserved for avoiding interference on subband 1 and subband2, and the portion of subband2 and subband3 need not be reserved for guard bands due to the LBT success.

For downlink broadband transmission, in order to increase the transmission opportunity of PDCCH, CORESET configuration is preferably defined in one LBT subband, and each UE performs configuration search space on each CORESET as much as possible. However, at the time of configuration, the result of LBT is uncertain, and whether the above-mentioned guard band is needed or not is also uncertain. In this case, the most straightforward approach is that CORESET considers the worst case when RRC configuration, i.e. CORESET configured on each LBT subband needs to be left with a guard band. Since the granularity of CORESET frequency domain configuration is 6 RBs, more than 6 RBs need to be vacated to meet the requirement of the guard band in some cases, which may cause great resource waste.

In order to solve the problem, in the embodiment of the present invention, since the configuration information configured for the network device and the UE is used to indicate M frequency domain positions of the target CORESET, when the network device configures the target CORESET, the first frequency domain position (the M frequency domain positions include the first frequency domain position) of the target CORESET can be flexibly adjusted according to the configuration information, so that unnecessary resource waste is reduced, and communication efficiency and efficiency are improved.

It should be noted that the resource adjustment scheme provided by the present invention may be applied to an unlicensed frequency band, and may also be applied to a licensed frequency band, which is not limited by the present invention.

Embodiment one:

fig. 2 is a flow chart illustrating a resource adjustment method according to an embodiment of the present invention, where the embodiment is mainly directed to a process for adjusting a frequency domain position of a target CORESET by a network device, as shown in fig. 2, the resource adjustment method may include:

step 201: and the network equipment adjusts the first frequency domain position of the target CORESET according to the configuration information.

In the embodiment of the present invention, the configuration information is used to indicate M frequency domain positions of the target CORESET, where the M frequency domain positions include a first frequency domain position, and M is a positive integer greater than 1. It should be noted that, in the embodiment of the present invention, the configuration information may indicate 1 or more frequency domain positions of one CORESET, or may indicate 1 or more frequency domain positions of each CORESET in a plurality of CORESETs, which is not limited in this aspect of the present invention.

In the embodiment of the present invention, the configuration information may be predefined or specified by a protocol.

Optionally, in an embodiment of the present invention, the configuration information includes: and numbering the bitmap of the resource block RB corresponding to each of the M frequency domain positions.

Optionally, in an embodiment of the present invention, the M frequency domain positions include at least one of the following: the frequency domain position of the unprotected frequency band, the frequency domain position of the upper edge guard band, the frequency domain position of the lower edge guard band and the frequency domain position of the upper edge guard band and the lower edge guard band, and M is less than or equal to 4.

For example, as shown in fig. 3, taking an example of an operation carrier as BWP, if the BWP has a bandwidth of 80MHz and the BWP has a subband length of 20MHz, the BWP includes 4 subbands, namely, subband 1, subband 2, subband3 and subband4, where CORESET1 is configured on subband 1, CORESET2 is configured on subband 2, CORESET3 is configured on subband3, and CORESET4 is configured on subband 4. Specifically, the base station may allocate one or more frequency domain resources for each CORESET, for example, the base station may configure bitmaps of RBs corresponding to 2 frequency domain positions (i.e., CORESET1-0 and CORESET 1-1) for CORESET1, may configure bitmaps of RBs corresponding to 4 frequency domain positions (i.e., CORESET2-0, CORESET2-1, CORESET2-2, CORESET 2-3) for CORESET2, may configure bitmaps of RBs corresponding to 4 frequency domain positions (i.e., CORESET3-0, CORESET3-1, CORESET3-2, CORESET 3-3) for CORESET3, and may configure bitmaps of RBs corresponding to 2 frequency domain positions (i.e., CORESET4-0 and CORESET 4-1) for CORESET4.

Referring to fig. 3, since subband 1 is an upper edge subband of the BWP, 2 frequency domain positions are allocated and the allocated frequency domain positions are all present in the upper edge guard band, and subband4 is a lower edge subband of the BWP, and therefore the 2 frequency domain positions are allocated and the allocated frequency domain positions are all present in the lower edge guard band. Since subband 2 and subband3 are intermediate subbands of the BWP and may or may not have guard bands between adjacent subbands (including: upper adjacent subband and lower adjacent subband, e.g., subband 1 is the upper adjacent subband of subband 2 and subband3 is the lower adjacent subband of subband 2), 4 frequency domain positions are configured.

Optionally, in the embodiment of the present invention, the configuration information is further used to indicate M frequency band states of one frequency domain configuration (i.e. the configuration information is used to configure multiple frequency band states of one frequency domain location), the M frequency band states are used to indicate the M frequency domain locations, and the M frequency band states include at least one of the following: the method comprises the steps of a no guard band state, an upper edge guard band on state, a lower edge guard band on state and an upper and lower edge guard band on state, wherein M is less than or equal to 4.

In one example, different band states may correspond to different numbers of bitmaps.

For example, as shown in fig. 4, taking an example of an operation carrier as BWP, if the BWP has a bandwidth of 80MHz and the BWP has a subband length of 20MHz, the BWP includes 4 subbands, namely, subband 1, subband 2, subband3 and subband4, where CORESET1 is configured on subband 1, CORESET2 is configured on subband 2, CORESET3 is configured on subband3, and CORESET4 is configured on subband 4.

Example 1: taking the target CORESET as CORESET2 as an example, the base station allocates a bitmap of a frequency domain resource corresponding to RB for CORESET2, and since subband 2 is the middle subband of the BWP, 4 band states may be defined for CORESET2, where the band states include: state 1, state 2, state 3 and state 4, wherein state 1 refers to a no guard band state (i.e. no guard band exists between the frequency domain position corresponding to state 1 and the frequency bands between the frequency bands 1 and 3), state 2 refers to an upper edge guard band on state (i.e. a guard band exists between the frequency domain position corresponding to state 2 and the frequency band 1), state 3 refers to a lower edge guard band on state (i.e. a guard band exists between the frequency domain position corresponding to state 3 and the frequency band 3), and state 4 refers to an upper and lower edge guard band on state (i.e. a guard band exists between the frequency domain position corresponding to state 4 and both the frequency bands 1 and 3).

Example 2: taking the target CORESET as CORESET1 as an example, the base station allocates a bitmap of a frequency domain resource corresponding to RB for CORESET1, and since subband 1 is an upper edge subband of the BWP, an upper edge guard band needs to be reserved, 2 band states can be defined for CORESET2, where the band states include: state 2 and state 4.

The size of the guard band in the frequency domain location in the present invention may be predefined or configured by RRC, which is not limited by the present invention.

Optionally, in the embodiment of the present invention, the network device may further configure the above configuration information to the UE, for example, before step 201, the method further includes the following step A1:

step A1: the network device sends the configuration information to the UE.

Correspondingly, the opposite-end UE receives the configuration information sent by the network equipment.

The network device in the embodiment of the present invention may be a network device in the communication system shown in fig. 1, for example, a base station; the UE in the embodiment of the present invention may be the UE in the communication system shown in fig. 1.

Optionally, in the embodiment of the present invention, when the network device adjusts the first frequency domain location of the target CORESET, the network device may adjust the first frequency domain location in combination with the LBT interception result.

Illustratively, prior to step 201, the method further includes:

step 201a1: the network device performs LBT interception on the first and second subbands in the operating carrier.

In combination with the step 201b1, the step 201 specifically includes the following steps:

step 201a2: and the network equipment adjusts the first frequency domain position of the target CORESET according to the interception result and the configuration information.

The first sub-band is a sub-band where the target CORESET is located, the second sub-band is a sub-band adjacent to the first sub-band in the operation carrier, and each of the M frequency domain positions is in the first sub-band.

In one example, the operating carrier may be an operating BWP.

Example 1: referring to the frequency domain configuration shown in fig. 3, the base station allocates one or more frequency domain resources for each CORESET. When the base station determines that subbands 2 and3 are available after LBT, taking target CORESET as CORESET2 and CORESET3 as an example, the base station adjusts the frequency domain position of CORESET2 to CORESET2-3 and the frequency domain position of CORESET3 to CORESET3-2.

Example 2: referring to the frequency domain configuration shown in fig. 4, the base station allocates a frequency domain resource to CORESET2, and when the base station determines that subbands 2 and3 are available after LBT is performed, the base station determines that the target band state of CORESET2 is state 2 (i.e., the upper edge guard band on state), and then adjusts the frequency domain position of CORESET2 based on state 2.

According to the resource adjustment method provided by the embodiment of the invention, the configuration information is used for indicating the M frequency domain positions of the target CORESET, so that when the network equipment configures the target CORESET, the first frequency domain position (the M frequency domain positions comprise the first frequency domain position) of the target CORESET can be flexibly adjusted according to the configuration information, unnecessary resource waste is reduced, and the communication efficiency and the efficiency are improved.

Embodiment two:

fig. 5 shows a flowchart of a resource adjustment method provided by the embodiment of the present invention, where the embodiment is mainly directed to a process for adjusting a frequency domain position of a target search space corresponding to a target core by a UE, as shown in fig. 5, the resource adjustment method may include:

step 301: and the UE determines a second frequency domain position of the target CORESET according to the configuration information.

Step 302: and the UE adjusts the frequency domain position of the target search space corresponding to the target CORESET according to the second frequency domain position.

In the embodiment of the present invention, the configuration information is used to indicate M frequency domain positions of the target CORESET, where the M frequency domain positions include a first frequency domain position and a second frequency domain position, and M is a positive integer greater than 1.

In the embodiment of the present invention, the target CORESET is adjusted from the first frequency domain position to the second frequency domain position. It can be appreciated that when determining the second frequency domain position of the target CORESET according to the configuration information, the UE adjusts the first frequency domain position of the target CORESET to the second frequency domain position, and further adjusts the frequency domain position of the target search space corresponding to the target CORESET based on the second frequency domain position.

In the embodiment of the invention, when the target CORESET is adjusted from the first frequency domain position to the second frequency domain position, the UE stops all the target search spaces associated with the target CORESET until the frequency domain position adjustment of the target search space is completed.

Optionally, in an embodiment of the present invention, the configuration information is predefined, or the configuration information is specified by a protocol, or the configuration information is configured by the network device for the UE.

It should be noted that, in this embodiment, the specific description of the configuration information in step 301 may refer to the related description of the configuration information for indicating M frequency domain positions of the target CORESET in embodiment one, which is not described herein.

In addition, if the UE side is configured with a start time and a valid time, the UE adjusts from a predetermined start time until the valid time is over, and the frequency domain configuration of the target CORESET is restored to a state before adjustment or a default state.

Optionally, in the embodiment of the present invention, when determining the second frequency domain location of the target CORESET according to the configuration information, the UE may determine the second frequency domain location in combination with an LBT interception result, where the LBT interception result refers to: and the network equipment monitors the LBT of the sub-bands in the running carrier wave to obtain a monitoring result. The interception result may be indicated to the UE by the network device through signaling, or may be detected by the UE through a specific reference signal (for example, a demodulation reference signal (Demodulation Reference Sgnal, DMRS)).

The process of obtaining the interception result by the UE through the downlink reference signal detection by itself may refer to the following:

illustratively, at step 301 described above, the method further includes:

step 301a1: the UE receives downlink reference information from the network device.

Step 301a2: and the UE detects the interception result according to the downlink reference signal.

The interception result is obtained after the network equipment performs LBT interception on a first sub-band and a second sub-band in an operation carrier, wherein the first sub-band is a sub-band in which a target CORESET is located, and the second sub-band is a sub-band adjacent to the first sub-band in the operation carrier.

In combination with the steps 301a1 and 301a2, the step 301 specifically includes the following steps:

step 301a3: and determining a second frequency domain position of the target CORESET according to the configuration information and the interception result.

Optionally, in an embodiment of the present invention, the step 302 specifically includes the following steps:

step 302b: and the UE adjusts the frequency domain position of the target search space corresponding to the target CORESET according to the second frequency domain position and a preset rule.

Wherein the predetermined rule includes at least one of: the adjustment is started at a first predetermined time, is adjusted within a predetermined period of time, is adjusted after a second predetermined time, is adjusted within a predetermined length of time, and is completed before a third predetermined time. For example, if there is no start time configuration, the first predetermined time may be a specific time when the UE receives a configuration command (e.g., PDCCH hereinafter), for example, when the UE receives a next slot of the configuration command, and if there is a start adjustment time configuration, the first predetermined time is a predetermined start adjustment time.

The first predetermined time, the second predetermined time, and the third predetermined time may be fixed values, or may be flexibly set according to the actual application scenario, which is not limited in the present invention.

According to the resource adjustment method provided by the embodiment of the invention, the configuration information is used for indicating the M frequency domain positions of the target CORESET, so that when the target CORESET is adjusted from the first frequency domain position to the second frequency domain position, the UE can determine the second frequency domain position of the target CORESET according to the configuration information, and then adjust the frequency domain position of the target search space corresponding to the target CORESET based on the second frequency domain position, so that when the frequency domain position of the target CORESET changes, the frequency domain position of the target search space corresponding to the target CORESET can be accurately adjusted, and the communication efficiency and efficiency are improved.

Embodiment III:

in combination with the solutions of the first and second embodiments, the solution provided in this embodiment is mainly aimed at informing, by the network device, the UE of the scenario of the adjustment result of the first frequency domain position of the adjustment target CORESET through the PDCCH. Fig. 6 shows a flowchart of a resource adjustment method according to an embodiment of the present invention, where, as shown in fig. 6, the resource adjustment method may include the following steps:

Step 401: and the network equipment adjusts the first frequency domain position of the target CORESET according to the configuration information.

Step 402: the network device transmits the PDCCH to the user equipment UE at the first frequency domain location.

Step 403: the UE receives a PDCCH from a network device at a first frequency domain location.

Step 404: and the UE determines a second frequency domain position of the target CORESET according to the configuration information and the PDCCH.

Step 405: and the UE adjusts the frequency domain position of the target search space corresponding to the target CORESET according to the second frequency domain position.

In the embodiment of the present invention, the configuration information is used to indicate M frequency domain positions of the target CORESET, where the target CORESET is adjusted from a first frequency domain position to a second frequency domain position, and the M frequency domain positions include the first frequency domain position and the second frequency domain position, and M is a positive integer greater than 1.

In the embodiment of the present invention, the PDCCH is used to indicate an adjustment result of the network device after the adjustment of the first frequency domain position. The PDCCH described above may also be a GC-PDCCH, for example.

In the embodiment of the invention, the UE receives the configuration information of the target search space associated with the target CORESET through RRC, then determines all the target search spaces associated with the target CORESET based on the configuration information of the target search space, and performs PDCCH detection according to default frequency domain allocation.

Optionally, the PDCCH is further used to indicate a start time or a valid time for adjusting the first frequency domain position.

Optionally, in the embodiment of the present invention, the PDCCH is further used to indicate a start time or a valid time for adjusting the first frequency domain position.

Optionally, in an embodiment of the present invention, the PDCCH is used to indicate a second frequency domain location.

Further optionally, in the embodiment of the present invention, the PDCCH is further used to indicate a number of a bitmap of the RB corresponding to the second frequency domain location.

Further optionally, in an embodiment of the present invention, the PDCCH is further used to indicate a target frequency band state of the second frequency domain location, where the target frequency band state includes any one of the following: a no guard band state, an upper edge guard band on state, a lower edge guard band on state, and an upper and lower edge guard band on state.

Optionally, in the embodiment of the present invention, in combination with the step 201a1 and the step 201a2, if the interception result is that the first subband is available, the PDCCH is used to indicate the second frequency domain location; or if the interception result is that the first sub-band is busy, the PDCCH is used for indicating that the target CORESET is invalid. Illustratively, if the first sub-band is available, the first frequency domain position of the target CORESET is adjusted, and if the first sub-band is busy, all CORESETs on the first sub-band become inactive, at which point any frequency domain bitmap of these CORESET configurations is inactive.

Optionally, in the embodiment of the present invention, in combination with the step 201a1 and the step 201a2, the PDCCH is further used to indicate the interception result.

Example 3: referring to the frequency domain configuration shown in fig. 3, the base station allocates one or more frequency domain resources for each core, and the UE performs PDCCH monitoring according to the default core configuration (i.e., core 1-0, core 2-0, core 3-0, core 4-0).

First, when the base station determines that subbands 2 and3 are available after LBT, taking target CORESET as CORESET2 and CORESET3 as an example, the base station adjusts the frequency domain position of CORESET2 to CORESET2-3 and the frequency domain position of CORESET3 to CORESET3-2. Then, the base station sends a PDCCH according to a default CORESET configuration, where the PDCCH is used to indicate the frequency domain positions (i.e., CORESET2-3 and CORESET 3-2) of CORESET2 and CORESET3 after being changed, and correspondingly, after performing PDCCH monitoring according to the default CORESET configuration, the UE obtains the PDCCH, obtains that the frequency domain positions of CORESET2 and CORESET3 are changed based on the PDCCH, and determines that the frequency domain positions of CORESET2 and CORESET3 after being changed are CORESET2-3 and CORESET3-2, respectively. Next, the UE adjusts the frequency domain positions of all search spaces associated with CORESET2 according to CORESET2-3, and the UE adjusts the frequency domain positions of all search spaces associated with CORESET3 according to CORESET3-2. Finally, all search spaces of the UE associated with CORESET2 perform PDCCH monitoring according to CORESET2-3, and all search spaces of the UE associated with CORESET3 perform PDCCH monitoring according to CORESET3-2.

Example 4: referring to the frequency domain configuration shown in fig. 4, the base station allocates one frequency domain resource for CORESET2 and defines 4 frequency band states (state 1, state 2, state 3 and state 4, respectively) for the frequency domain resource, and the UE performs PDCCH monitoring according to the default state 1. First, when the base station determines that subbands 2 and3 are available after LBT is performed, the base station determines that the target band state of CORESET2 is state 2 (i.e., the upper edge guard band on state), i.e., the upper edge guard band is turned on, and then adjusts the frequency domain position of CORESET2 based on state 2. Then, the base station may send a PDCCH according to the state 1, where the PDCCH may carry an LBT interception result, and correspondingly, after the UE performs PDCCH monitoring according to the default state 1, the UE obtains the PDCCH, and then, based on the PDCCH, the UE may learn that the target frequency band state of CORESET2 is state 2, and then adjust the frequency domain position of CORESET2 to the frequency domain position corresponding to state 2. When the COT ends, the user restores the band state of CORESET2 from state 2 to state 1.

It should be noted that, the specific description of the step 401 in this embodiment may refer to the description related to the first embodiment, the specific descriptions of the step 404 and the step 405 in this embodiment may refer to the description related to the second embodiment, and the description of this embodiment is not repeated.

According to the resource adjustment method provided by the embodiment of the invention, since the configuration information is used for indicating the M frequency domain positions of the target CORESET, when the network equipment configures the target CORESET, the first frequency domain position (the M frequency domain positions comprise the first frequency domain position) of the target CORESET can be flexibly adjusted according to the configuration information, and the adjusted frequency domain position (namely the second frequency domain position) of the target CORESET is informed to the UE by sending the PDCCH to the UE, so that the UE can determine the second frequency domain position of the target CORESET according to the configuration information and the PDCCH, and then adjust the frequency domain position of the target search space corresponding to the target COESET based on the second frequency domain position, when the frequency domain position of the target COESET changes, not only can unnecessary resource waste be reduced, but also the frequency domain position of the target search space corresponding to the target COESET can be accurately adjusted, and communication efficiency and efficiency can be improved.
