Description

Resource determination method, device, terminal, network equipment and readable storage medium

Technical Field

The application belongs to the technical field of communication, and particularly relates to a resource determining method, a device, a terminal, network side equipment and a readable storage medium.

Background

As communication technologies develop, various reference signals are generally required to be transmitted in a communication system, and for example, a long term evolution (Long Term Evolution, LTE) cell reference signal (Cell Reference Signal, CRS) and a physical downlink control channel (Physical Downlink Control Channel, PDCCH) demodulation reference signal (Demodulation Reference Signal, DMRS) may be included. In order to avoid collision between a New Radio (NR) PDCCH and an LTE CRS, so as to affect measurement of the CRS by the LTE terminal and affect decoding of the NR PDCCH by the NR terminal, network side equipment needs to ensure that NR PDCCH symbols do not overlap with LTE CRS symbols, i.e. the network side equipment allocates different symbols to the NR PDCCH and the LTE CRS. Since LTE CRS and NR PDCCH are allocated different symbols, the overhead that can be allocated to NR PDCCH resources may be limited by CRS, so that scheduling opportunities for NR within one subframe are also limited by CRS, resulting in affecting transmission performance.

For ease of understanding, some of the matters related to the embodiments of the present application are described below:

1. LTE CRS

LTE CRS is a periodically and continuously transmitted RS, and the Resource Element (RE) positions occupied by LTE CRS and LTE PDCCH in one subframe are shown in fig. 2a and fig. 2 b; the number of symbols and the number of REs that LTE CRS may occupy within a multicast/multicast single frequency network resource (Multicast Broadcast Single Frequency Network, MBSFN) subframe and within a non-MBSFN subframe are different.

2. NR PDCCH DMRS

The NR PDCCHs may occupy one or more Resource Blocks (RBs) of the frequency domain, each PDCCH RB containing DMRS therein, and PDCCH DMRS occupies REs of numbers 1, 5, and 9 within each PDCCH RB, wherein the numbers of REs start from 0.

3. NR PDCCH and NR PDCCH DMRS under dynamic Spectrum sharing (Dynamic Spectrum Sharing, DSS)

LTE and NR may dynamically share the same carrier frequency resource, DSS. In order to avoid collision between the NR PDCCH and the LTE CRS and thus influence the measurement of the CRS by the LTE terminal and influence the decoding of the NR PDCCH by the NR terminal, the network side device needs to ensure that the NR PDCCH symbol does not overlap with the LTE CRS symbol, i.e. the network side device allocates different symbols to the NR PDCCH and the LTE CRS. For example, since LTE CRS occupies symbols 0 and 1, the NR PDCCH can only start from symbol 2.

Thus, since LTE CRS and NR PDCCH are allocated different symbols, the overhead that can be allocated to NR PDCCH resources may be limited by CRS, and thus scheduling opportunities for NR within one subframe may also be limited by CRS. With the increase of NR terminals, the limited scheduling opportunities seriously affect the performance of the NR system. It is therefore desirable to allow configuration of NR PDCCH and LTE CRS to share time domain symbols and/or frequency domain resources, provide capacity of NR PDCCH, and to avoid collision of NR PDCCH DMRS and CRS to interfere with each other, affecting performance of LTE and NR. The transmission method of the present application is presented for this purpose.

The resource determining method provided by the embodiment of the application is described in detail below by some embodiments and application scenarios thereof with reference to the accompanying drawings.

Referring to fig. 3, an embodiment of the present application provides a resource determining method, including:

step 301, a terminal determines a first offset;

step 302, the terminal offsets according to a first offset based on a reference resource;

and step 303, the terminal determines the offset resource as a target downlink resource.

In this embodiment of the present application, the target downlink resource is a resource for transmitting a target downlink signal or a target downlink channel, and the target downlink signal may also be referred to as a target downlink channel. The target downlink signal may include at least one of PDCCH and RS, and further, the target downlink signal may include at least one of NR PDCCH and NR RS. The above-mentioned target downlink resource may be understood as an RS resource for transmitting an RS, a resource for transmitting a PDCCH, or a resource for transmitting a PDCCH and an RS, which are not further limited herein. Wherein the RS resource may be a PDCCH DMRS resource. Further, it may be DMRS resources of user-specific PDCCH (UE specific PDCCH), such as the resources of PDCCH DMRS in UE specific CORESET.

Optionally, the first offset is obtained by a network side device configuration, a network side device indication, a protocol commitment or the terminal derivation.

It should be understood that the above network side device configuration may be understood that the network side device is explicitly or implicitly configured by a synchronization signal block (Synchronization Signal and PBCH block, SSB) and/or a radio resource control (Radio Resource Control, RRC). The network-side device indication may be understood as an explicit or implicit indication of the network-side device by means of a medium access control unit (Medium Access Control Control Element, MAC CE), downlink control information (Downlink Control Information, DCI) and/or other RSs.

Further, the configuration may be configuring the relevant information of the target downlink resource, or configuring the identifier corresponding to the relevant information of the target downlink resource, where the identifier may be understood as an index (index) or an Identity (ID). The indication may be related information indicating the target downlink resource or an identifier corresponding to the related information indicating the target downlink resource. The above specification may be information related to the specification of the target downlink resource or an identifier corresponding to the information related to the specification of the target downlink resource.

It should be noted that, the determining, by the terminal, that the target downlink resource is offset according to the first offset based on the reference resource may be understood as actually avoiding overlapping of the first resource and the target downlink resource by adjusting the configuration of the first resource and the position of the target downlink resource, where the overlapping of the first resource and the target downlink resource may be understood as collision of the first resource and the target downlink resource, and the first resource may be understood as other resources except the target downlink resource. This may allow the target downlink resource and the first resource to be located within the same symbol, e.g., LTE CRS and NR PDCCH may be allocated on the same symbol. Since the configuration of the NR PDCCH and the LTE CRS may be allowed to share time domain symbols and/or frequency domain resources, the capacity of the NR PDCCH may be provided, and collision between NR PDCCH DMRS and CRS may be avoided to interfere with each other, affecting transmission performance of LTE and NR.

It should be noted that the offset in the embodiment of the present application may be understood as an interval. The offset between SFN0 of LTE and SFN0 of NR can also be interpreted as the interval between them.

Optionally, the target downlink resource may include at least one of:

frequency resources of the target downlink signal;

time domain resources of the target downlink signal;

code domain resources of the target downlink signal;

the frequency domain resources may include at least one of REs, RBs, resource element groups (Resource Element Group, REGs), REG bundling (Bundle), control channel elements (Control Channel Element, CCEs), candidates PDCCH (PDCCH candidate), control resource sets (Control resource set, CORESET), bandwidth parts (BWP), carriers (carrier), frequency bands (band), frequency ranges (frequency ranges), and the like.

The resources for the time domain may include at least one of symbols, slots (slots), sub-slots, frames (frames), and subframes (subframes) occupied by the target downlink resources.

Optionally, in some embodiments, the determining, by the terminal, the first offset includes:

the terminal determines a first offset according to an association relation between a first resource and the first offset, wherein the first resource is a resource except the target downlink resource.

In this embodiment of the present application, the association relationship between the first resource and the first offset includes at least one of the following: and the first resource and the identifier corresponding to the first offset are associated with each other, and the identifier corresponding to the first resource and the identifier corresponding to the first offset are associated with each other.

Alternatively, the first offset may be a positive number, 0, or a negative number. Optionally, in some embodiments, the first resource includes an LTE resource, for example, may include an uplink LTE resource or a downlink LTE resource. Further, the downlink resource used for CRS by the LET may also be set. In some embodiments, the first resource may include one or more CRS resources, for example, may be configured CRS resources, or may be indicated or switched CRS resources. Further in some embodiments, the first resource may be further understood as timing information of the LTE resource, where the timing information may include at least one of the following: subframe boundaries, frame boundaries, locations of resource bins, boundaries of resource bins, locations of RBs, boundaries of RBs, locations of REs, and boundaries of REs.

It should be understood that the association relationship may be understood as a mapping relationship, and the above identification may be understood as an index (index) or an Identification (ID).

Optionally, the offset by the terminal according to the first offset based on the reference resource includes:

and the terminal performs at least one offset according to the first offset based on the reference resource, wherein the offset resource does not overlap with at least part of the first resource, and the first resource is a resource except the target downlink resource.

In the embodiment of the present application, the number of times of offset may be agreed by a protocol or configured or indicated by a network side device, which is not further limited herein.

Optionally, in some embodiments, the offset by the terminal by the first offset based on the reference resource includes:

and the terminal performs N times of offset according to the first offset based on the reference resource until the offset resource does not overlap with at least part of the resources in the first resource, wherein N is a positive integer, and the first resource is a resource except the target downlink resource.

Optionally, the first offset includes one offset value, the offset values corresponding to the N offsets are the same, or the first offset includes at least two offset values, and the offset values corresponding to at least two offsets in the N offsets are different.

In this embodiment of the present application, after performing the offset once, if the offset resource still overlaps or collides with at least a portion of the first resource, the offset resource is further offset until the offset resource does not overlap or collide with all or a preset portion of the first resource. Preferably, the offset resource does not overlap with all of the resources in the first resource.

Alternatively, one interpretation of the above-mentioned reference resources may be: the reference resource is an available resource of the RS and/or PDCCH, and thus the overlapping portion is a portion of the overlap of the available resource and the first resource.

In some embodiments, another explanation of the above-described reference resources may be: at least one of a preset frequency domain reference resource and a time domain reference resource.

Wherein, the frequency domain reference resource may include at least one of the following:

RE#1 and/or RE#5 and/or RE#9;

the RB and/or REG buffer and/or CCE and/or PDCCH candidate and/or CORESET and/or bwp and/or carrier and/or cell and/or band and/or frequency range where the NR PDCCH or NR PDCCH DMRS is located or associated or belongs to.

The time domain resource may include at least one of:

at least one of symbols where NR PDCCH and/or CORESET is located;

at least one of symbols in which the CRS is located;

at least one of symbol 0, symbol 1, symbol 4, symbol 7, symbol 8, and symbol 11;

at least one of symbol 0, symbol 1, symbol 3, symbol 6, symbol 7, and symbol 9.

Further, the terminal may also assume that the cell-level target downlink resource or the common target downlink resource or the broadcasted target downlink resource does not overlap and/or collide with the first resource, and/or that there is no information or the first offset related to the corresponding target downlink resource. The target downlink resource at the terminal level or the dedicated target downlink resource or the unicast target downlink resource may have corresponding information or first offset of the target downlink resource.

Optionally, the first offset includes at least one of a time domain offset, a frequency domain offset, a spatial domain offset, and a code domain offset.

For example, after acquiring the first time domain offset (i.e., the time domain offset contained in the first offset), the UE assumes that the frequency domain resources determined based on the first time domain offset are used for transmission PDCCH DMRS.

In this embodiment of the present application, the second offset may be configured by a network side device, an indication of the network side device, or a protocol contract. The second offset includes at least one of a time domain offset, a frequency domain offset, a spatial domain offset, and a code domain offset. The first offset is related to the second offset, e.g. the first offset is derived based on the second offset, e.g. the first offset is equal to the second offset.

Optionally, the second offset may specifically include at least one of: resource grid offset, resource block RB offset, resource element RE offset, slot offset, subframe offset, frame offset, and symbol offset.

In other words, in the present embodiment, the second offset may be understood as at least one of the following:

offset between LTE and NR resource bins;

offset between RBs of LTE and RBs of NR;

offset between REs of LTE and REs of NR;

Offset between slots of LTE and slots of NR (e.g. with the same slot index);

offset between subframes of LTE and subframes of NR (e.g. with the same subframe index);

offset between the symbol of LTE and the symbol of NR (e.g. with the same symbol index).

Alternatively, the above-mentioned association relationship may also be referred to as a mapping relationship.

Alternatively, in some embodiments, the terminal may determine the first offset based on an association relationship between the first resource and the first offset. The association relationship between the first resource and the first offset may be determined based on at least one of the following, or the concrete expression form of the association relationship between the first resource and the first offset may be represented by at least one of the following:

the first resource configuration comprises a first offset;

the first resource configuration comprises a first offset ID or index;

the first offset configuration comprises configuration information of a first resource;

the first offset configuration includes an ID or index of configuration information of the first resource.

It should be understood that the configuration in the embodiment of the present application may be a configuration provided by a network side device, a predefined configuration, or alternatively, if the protocol is directly agreed, such agreement may be regarded as a configuration.

Optionally, in some embodiments, the first offset further satisfies at least one of:

the configuration corresponding to the preset target object comprises the associated first offset or the identifier of the associated first offset;

the configuration of the first offset comprises the configuration or the identification corresponding to the associated preset target object;

the configuration of the first offset comprises the first offset and the identification corresponding to the associated preset target object.

The configuration corresponding to the preset target object includes an identifier of an associated first offset, for example, the configuration of coreset#2 includes the first offset, which means that the preset target object associated with the first offset is coreset#2, and the first offset needs to be considered (consider) when determining PDCCH DMRS resources in coreset#2.

The configuration of the first offset includes a configuration or identifier corresponding to the associated preset target object, for example, the configuration of the first offset includes an ID of corset#2, which means that the preset target object associated with the first offset is coreset#2, and the first offset needs to be considered when determining PDCCH DMRS resources in coreset#2.

The configuration of the related information includes the identifier corresponding to the first offset and the associated preset target object, for example, the configuration of the related information includes id=1, where id=1 may be understood as a combination of the first offset 1 and CORESET 1.

For example, if the preset target object associated with the first offset is coreset#2 (e.g., the resource where the overlapping portion belongs to coreset#2, or there is an overlap between coreset#2 and CRS), then the first offset needs to be considered in determining PDCCH DMRS resources in coreset#2 (e.g., the resource after performing the first offset on the basis of the reference resource is the actual resource of PDCCH DMRS in coreset#2), and/or PDCCH DMRS of other non-associated CORESETs may not need to consider performing the first offset.

For example, if the preset target object associated with the first offset is the symbol where the overlapping portion is located, for example, the associated preset target object is symbol 1 (for example, the overlapping portion is symbol 1, or some frequency domain resources and CRSs overlap on symbol 1), the first offset needs to be considered in determining the PDCCH DMRS resources of symbol 1 (for example, the resources after the first offset are performed on the basis of the reference resources are actual resources of the symbol 1PDCCH DMRS), and/or PDCCH DMRS of other symbols may not need to be considered in performing the first offset.

For example, if the preset target object associated with the first offset is the symbol and the RE where the overlapping portion is located, for example, the associated preset target object is the re#9 of the symbol 1 (for example, the overlapping portion is the re#9 of the symbol 1), the first offset needs to be considered when determining the PDCCH DMRS resource of the re#9 originally corresponding to the symbol 1 (for example, the resource after the first offset is performed on the basis of the reference resource is the actual resource, specifically, the DMRS of the original re#9 is moved to the re#10), and/or PDCCH DMRS of other symbols and/or other REs may not need to be considered when performing the first offset (for example, the re#1 and/or the re#5 are still used for PDCCH DMRS).

Optionally, the preset target object is associated with at least one of the following:

at least part of the resources in the overlapping portion of the first resource and the reference resource;

at least a portion of the resources occupied by the target downlink resources;

at least a portion of the resources occupied by the first resource;

at least a portion of the resources occupied by the reference resources;

wherein the first resource is a resource other than the target downlink resource.

In the embodiment of the present application, the available target downlink resource may be understood as being used for the target downlink resource or actually used for the target downlink resource.

Optionally, the target object includes any one of the following: symbols, subframes, frames, slots, RE, RB, REG, REG bundling, CCEs, candidates PDCCH, CORESET, spans, listening opportunities, search spaces, timers, periods, durations, BWP, carriers, subcarriers, cells, bands, and frequency ranges.

In this embodiment of the present application, if the first resource and the reference resource may overlap and/or collide, or the first resource includes at least a portion of the reference resource, or the reference resource includes at least a portion of the first resource, the preset target object is associated with at least one of the following: at least part of the resources in the overlapping portion of the first resource and the reference resource; at least a portion of the resources occupied by the target downlink resources; at least a portion of the resources occupied by the first resource; at least part of the resources occupied by the reference resources.

For example, the preset target object may be interpreted as being at least part of the overlapping portion and/or the collision portion or being at or associated with (e.g. one or more) symbol and/or slot and/or RE and/or RB and/or REG band and/or CCE and/or PDCCH candidate and/or CORESET and/or span and/or Monitoring occasion and/or search space and/or timer and/or periodicity and/or duration and/or bwp and/or carrier and/or cell and/or band and/or frequency range.

For example, the CRS resources on symbol 1 contain REs #9 on RBs #1 to 8 (i.e., from RB #1 up to RB # 8), the reference resources on symbol 1 contain REs #9 of RBs #1 to 3, i.e., the CRS resources and the reference resources overlap at REs #9 of RBs #1 to 3 of symbol 1, there are the following cases:

for example, RBs # 1-3 on any symbol and/or RBs # 1-3 on any symbol 1 and/or RBs # 1-3 on overlapping slots that occur and/or RBs # 1-3 on overlapping symbol 1 that occur may be interpreted as the associated preset target object;

for example, RB#1-3 on any symbol 1 and/or RB#1-3 on the overlapping symbol 1 that occurs may be interpreted as the associated preset target object, or RB#1-3 on any symbol 1 and/or RB#1-3 on the overlapping symbol 1 that occurs may be interpreted as the associated preset target object.

Further, the target object may be a code rate dimension resource, a time domain dimension resource, a frequency domain dimension resource, or a time-frequency domain dimension resource.

Resources for the time domain dimension may be understood as symbols and/or slots and/or spans and/or Monitoring occasion and/or search space and/or timer and/or periodicity and/or duration where the overlapping and/or collision portion and/or first resource and/or reference resource is located or associated or belongs to. Resources for the frequency domain dimension may be understood as RBs and/or REGs and/or REG bundles and/or CCEs and/or PDCCH candidates and/or bwp and/or carriers and/or cells and/or bands and/or frequency ranges where the overlapping and/or collision portions and/or first resources and/or reference resources are located or associated or belong to. Resources for the time-frequency domain dimension may be understood as CORESET and/or BWP and/or cells (cells).

It should be appreciated that the timer described above is the time that the specified timer is running.

Optionally, the preset target object is associated with a control parameter.

For example, if one or more objects are associated with the control parameter, the associated preset target objects determined according to the values may be different when the values are different. In other words, in some embodiments, at least two values of the control parameter are associated with different target objects.

Optionally, if the control parameter takes the first value, the associated preset target object is CORESET, and the CORESET may be the CORESET where the overlapping portion and/or the collision portion and/or the first resource and/or the reference resource are located or associated or belong to. For example, when the control parameter pre-coding granularity is RB (allContiguousRBs), the associated preset target objects are all RBs of CORESET where the above overlapping portion and/or collision portion and/or first resource and/or reference resource are located or associated or belong to.

If the control parameter takes the value of the second value, the associated preset target object is an RE and/or an RB and/or an REG Bundle, where the RE may be an RE where the overlapping portion and/or the collision portion and/or the first resource and/or the reference resource is located or associated with or belongs to, the RB may be an RB where the overlapping portion and/or the collision portion and/or the first resource and/or the reference resource is located or associated with or belongs to, and the REG Bundle may be an REG Bundle where the overlapping portion and/or the collision portion and/or the first resource and/or the reference resource is located or associated with or belongs to. For example, when the control parameter precoding granularity is equal to the precoding granularity (precoding granularity), the associated preset target object is the above overlapping portion and/or collision portion and/or RE and/or RB and/or REG Bundle where the first resource and/or reference resource is located or associated or belongs to.

For example, the network side device provides two sets of CRS configurations, and then the network side device provides a set of first offsets for the two sets of CRS configurations, respectively.

Optionally, the first offset satisfies at least one of:

Embodiment one:

as shown in fig. 4, the CRS has 4 ports, P0, P1, P2, and P3, and re#0, re#3, re#6, and re#9 occupying symbol 1, and if symbol 1 is used for NR PDCCH, reference resources re#1 and/or re#5 and/or re#9 of NR PDCCH DMRS collide with the CRS at re#9. At this time, the network side device configures the first offset, and the terminal determines the RS resource by performing the first offset on the basis of the reference resource, for example, the first offset is 1RE or +1re, and the reference resource is re#1 and/or re#5 and/or re#9, and the determined RS resource is re#2 and/or re#6 and/or re#10.

For example, if the terminal is configured with a 1-port CRS and the CRS occupies re#0 and/or re#re#6 on a certain symbol, the RS resources used for transmission may be re#1 and/or re#5 and/or re#9.

As shown in fig. 6, the possible RS resources for transmission may be re#2 and/or re#6 and/or re#10, or the possible RS resources for transmission may be re#0 and/or re#4 and/or re#8, or the possible RS resources for transmission may be re#1 and/or re#5, or the possible RS resources for transmission may be re#7 and/or re#11.

For example, if the terminal is configured with a 1-port CRS and the CRS occupies re#3 and/or re#9 on a certain symbol, the RS resources used for transmission may be re#2 and/or re#6 and/or re#10.

As shown in fig. 7, the possible RS resources for transmission are re#1 and/or re#4 and/or re#7 and/or re#10, or the possible RS resources for transmission may be re#2 and/or re#5 and/or re#8 and/or re#11;

For example, if the terminal is configured with 4-port CRS and the CRS occupies re#0 and/or re#3 and/or re#6 and/or re#9 on a certain symbol, the RS resources used for transmission may be re#1 and/or re#4 and/or re#7 and/or re#10.

For example, if the terminal is configured with a 1-port CRS and the CRS occupies re#0 on a certain symbol, the RS resources used for transmission may be re#4 and/or re#10.

As shown in fig. 9, when the density of RSs possible for transmission is 1 and/or re#6, or the density of RSs possible for transmission is 2RE, the RS resources possible for transmission is re#0 and/or re#6, or the RS resources possible for transmission may be re#1 and/or re#7, or the RS resources possible for transmission may be re#2 and/or re#8, or the RS resources possible for transmission may be re#4 and/or re#10, or the RS resources possible for transmission may be re#5 and/or re#11.

For example, if the terminal is configured with 2-port CRS and the CRS occupies re#0 and/or re#3 and/or re#6 and/or re#9 on a certain symbol, the RS resources used for transmission may be re#5 and/or re#11;

Embodiment III:

suppose NR PDCCH DMRS originally transmitted on re#1 and/or re#5 and/or re#9, i.e., suppose NR PDCCH DMRS that the reference resource is re#1 and/or re#5 and/or re#9 within each RB on the symbol occupied by NR CORESET.

Case 1, the LTE carrier frequency domain range and the NR carrier frequency domain range overlap completely, so that the LTE carrier frequency domain range includes CORESET1, and if CRS and NR PDCCH DMRS of the LTE carriers overlap and/or collide, there is overlap and/or collision in the entire CORESET1 frequency domain range.

In case 2, the nr carrier frequency domain range includes LTE carrier 1, where the LTE carrier 1 frequency domain range and the CORESET1 frequency domain range partially overlap, and if CRS and NR PDCCH DMRS of the LTE carrier overlap and/or collide, only part of the CORESET1 frequency domain resources overlap and/or collide; the first offset may only refer to the overlapping and/or collision part, for example, the NR PDCCH DMRS position of the overlapping and/or # collision part in the figure needs to be offset, alternatively, the NR PDCCH DMRS position of the non-overlapping and/or collision part in the CORESET frequency domain does not need to be offset, and thus, transmission can be performed on re#1 and/or re#5 and/or re#9.

In case 3, the nr carrier frequency domain range includes LTE carrier 1 and LTE carrier 2, where the coreset1 frequency domain range overlaps with LTE carrier 1 and LTE carrier 2, respectively, and since CRS configurations of LTE carrier 1 and LTE carrier 2 may be different, if overlapping and/or collision occurs between NR PDCCH DMRS in coreset1 and CRS of LTE carrier 1 and LTE carrier 2, overlapping and/or collision occurs between NR PDCCH DMRS in coreset1 and CRS of LTE carrier 1 and LTE carrier 2, respectively, REs may be different. At this time, the different overlapping and/or collision parts may have respective associated and/or corresponding first offsets, for example, overlapping and/or collision parts of CORESET1 and LTE carrier 1, and overlapping and/or collision parts of CORESET1 and LTE carrier 2, respectively corresponding to first offset 1 and first offset 2.

In case 4, the nr carrier frequency domain range includes LTE carrier 1 and LTE carrier 2, where the LTE carrier 1 frequency domain range overlaps with the CORESET1 frequency domain range and the CORESET2 frequency domain range, and the frequency domain range CRS in LTE carrier 1 overlaps with the CORESET1 and the CORESET2 NR PDCCH DMRS, and the RE numbers of the overlapping and/or collision may be the same. At this time, the different overlapping and/or collision parts may have respective associated and/or corresponding first offsets, for example, overlapping and/or collision parts of CORESET1 and LTE carrier 1, and overlapping and/or collision parts of CORESET2 and LTE carrier 1, respectively corresponding to first offset 1 and first offset 2.

Embodiment four:

1. assuming that the network side device configures the first offset or the protocol specifies the first offset or the UE pushes the first offset, then:

the resources of NR PDCCH DMRS are determined based on the first offset only on resources where an overlap and/or collision occurs (e.g., RBs and/or REGs and/or REG window and/or CCEs and/or RBs of PDCCH candidate and/or CORESET where a collision occurs), and/or the portion of the resources where no overlap and/or collision occurs remain based on the reference resources to determine NR PDCCH DMRS resources;

or alternatively, the process may be performed,

the resources of NR PDCCH DMRS are determined based on the first offset only on the resources where the overlap and/or collision occurred (e.g., the symbol and/or slot and/or span and/or MO and/or periodicity and/or duration and/or timer where the collision occurred) and/or the portion of the resources where no overlap and/or collision occurred remain based on the reference resources to determine NR PDCCH DMRS resources.

2. Assuming that the resource information or protocol of the network side device configuration NR PDCCH DMRS specifies the resource information of NR PDCCH DMRS or the resource information of NR PDCCH DMRS is derived by the UE, then:

the NR PDCCH DMRS transmission is performed based on the obtained NR PDCCH DMRS resource information only on the resources where the overlap and/or collision occurs (e.g., the RBs and/or REGs and/or REG window and/or CCEs and/or PDCCH candidate and/or CORESET RBs) and/or the resource portions where no overlap and/or collision occurs still determine NR PDCCH DMRS resources based on the reference resources;

or alternatively, the process may be performed,

the NR PDCCH DMRS transmission is based on the above NR PDCCH DMRS resource information only on the resources where the overlap and/or collision occurs (e.g., the symbol and/or slot and/or span and/or MO and/or periodicity and/or duration and/or timer where the collision occurs) and/or the portion of the resources where the overlap and/or collision does not occur is still based on the reference resources to determine NR PDCCH DMRS resources.

Optionally, relevant information or a first offset of the RS resource is contained in the CORESET configuration, e.g. the first offset is contained in a CORESET cell (Information element).

Fifth embodiment:

The resources on which overlap and/or collision occurs (e.g., the RBs of RB and/or REG window and/or CCE and/or PDCCH candidate and/or CORESET that occur) and the portion of the resources included in the specific object that do not occur are both determined NR PDCCH DMRS based on the first offset;

such as an overlap of CORESET2 and CRS, but the resources of NR PDCCH DMRS within all CORESETs need to be determined based on the first offset.

the resource where overlap and/or collision occurs (e.g., RB and/or REG band and/or CCE and/or PDCCH candidate and/or CORESET RB) and the resource where overlap and/or collision does not occur within the resources contained in the specific object are all transmitted NR PDCCH DMRS based on the obtained resource information of NR PDCCH DMRS.

Such as an overlap of CORESET2 and CRS, all resources of NR PDCCH DMRS within CORESET need to be determined based on the obtained NR PDCCH DMRS resource information.

Example six:

it is assumed that the network side device configures the first offset and configures associated target object information, for example, in the portion where the symbol of the associated target object is symbol 1, i.e. overlapping and/or collision occurs, only RS resources on symbol 1 are determined based on the first offset.

It should be noted that, in the embodiment of the present application, the PDCCH DMRS located REs included in each column including PDCCH DMRS in fig. 5 to 9 correspond to one possible RS resource.
