Abstract

The application discloses a resource mapping method; the method is applied to the terminal side, wherein the method comprises the following steps: determining a first set of resources; wherein, the RE related to the first resource set is unavailable for downlink channel transmission, downlink signal transmission, uplink channel transmission, and/or uplink signal transmission.

Description

Resource mapping method and device, equipment and storage medium
Technical Field
The present application relates to communications technologies, and in particular, but not limited to, resource mapping methods and apparatuses, devices, and storage media.
Background
The digital intelligence can permeate into aspects of production and life, and 5G is an important carrier for constructing the trillion parts per billion in the future. The machine vision related services such as wearable equipment, smart city cameras, cloud storage, digital twinning and the like generate mass data from bottom to top; production control and machine cooperation in the industrial internet also put higher demands on time delay. The construction of gigabit uplink and low-delay communication capability is a common requirement for intelligent upgrade of the 5G network enabling number in the future. In the 5G present network, the need for deploying a large upstream network in a factory industry private network scenario of smart ports, smart steels, smart mines, and the like has emerged.
To cater for the gigabit upstream and low latency communication capabilities required for future digital intelligence upgrades, further mining of Time-Division Duplex (TDD) spectrum potential is required to unlock full Duplex (full Duplex) networking potential. In some embodiments, a base station side sub-band non-overlapping full duplex (SBFD) technique may be applied on the TDD spectrum, while the terminal side still employs an entirely new duplex scheme of the TDD technique. For the full duplex mode with non-overlapping sub-bands, when seen from the base station side, there is both uplink transmission and downlink transmission in the same time slot of the TDD spectrum, but the time-frequency resources of the uplink and downlink transmission are not overlapped; from the terminal side, the system still adopts a TDD system, but different terminals may see different TDD frame structure configurations.
Compared with a TDD system, the SBFD can obviously enhance the uplink coverage capacity, improve the uplink throughput and reduce the air interface delay of a user.
The third generation partnership project (3rd Generation Partnership Project,3GPP) standardizes the rate matching mode technique for downlink transmission at the resource block-symbol (RB-symbol) level, however, its application range is too narrow to meet the requirements in full duplex scenarios.
Disclosure of Invention
In view of this, the resource mapping method, the device, the equipment and the storage medium provided by the application, the first resource set not only can be used for carrying out rate matching on the downlink channel, but also can be used for carrying out rate matching on the downlink signal and the uplink channel and/or the uplink signal, so that the rate matching on the uplink and downlink channels and/or the signals under the full duplex scene can be realized.
According to an aspect of an embodiment of the present application, there is provided a resource mapping method, applied to a terminal side, including: determining a first set of resources; wherein, the RE related to the first resource set is unavailable for downlink channel transmission, downlink signal transmission, uplink channel transmission, and/or uplink signal transmission.
In some embodiments, the first set of resources is a set of rate matching resources.
In some embodiments, the determining the first set of resources includes: determining the first resource set according to at least one of a first parameter, a second parameter and a third parameter; wherein,
the first parameter is used for determining frequency domain resources of the first resource set;
the second parameter is used for determining time domain resources of the first resource set;
The third parameter is used to determine at least one of a transmission direction, at least one channel, and at least one signal of the first set of resources.
In some embodiments, the first parameter is used to indicate any one of the following information:
a bitmap (bitmap) at Resource Block (RB) level;
a resource block group (Resource Block Group, RBG) level bitmap;
a bitmap of a partial Bandwidth (BWP) level;
subband (Subband) level bitmap;
at least one first value;
at least one seventh parameter, the seventh parameter comprising: a start RB offset and a continuously allocated RB length;
and a third value combination number indication.
In this embodiment, the first parameter may not only indicate the frequency domain resource with smaller granularity (such as RB level and/or RBG level) by using a bitmap indication manner, but also indicate the frequency domain resource with larger granularity (such as BWP level and/or Subband level) by using a bitmap indication manner; while signaling overhead may be reduced.
Further, the first parameter may also indicate the first value or the initial RB offset and the continuously allocated RB length in a section of continuous frequency domain resource, without indicating the rate matching manner of each RB one by one like the bitmap indication method, so that signaling indication overhead may be significantly reduced.
Furthermore, the first parameter may also indicate the start RB position and the end RB position of each of the two continuous frequency domain resources in the form of a combination number, which further significantly reduces signaling indication overhead compared to a manner of indicating the two continuous frequency domain resources by using 2 first values.
In some embodiments, the second parameter is used to indicate any one of the following information:
symbol (Symbol) level bitmap;
symbol-level bitmap and time-domain repetition pattern (time domain repetition pattern);
a first period and at least one second value;
the first period and at least one eighth parameter, the eighth parameter comprising: a start symbol S and an allocation length L;
a second value, a first period, and a first offset;
a start symbol S, an allocation length L, a first period and a first offset.
In this embodiment, the second parameter may indicate the second value or the initial symbol offset and the continuously allocated symbol length in a section of continuous time domain resource in the first period, so as to avoid a rate matching manner that the bitmap indication method indicates each symbol one by one, thereby significantly reducing signaling indication overhead.
Further, if the first resource set includes multiple continuous time domain resources in the time domain in the first period, the two continuous time domain resources can be "spliced" into one continuous time domain resource by applying the first offset, so that the two continuous time domain resources can be indicated by using the indication parameter (i.e. the start symbol S and the allocation length L) of the one continuous time domain resource, and signaling indication overhead is further significantly reduced.
In this embodiment, the third parameter may be used to determine a transmission direction and/or indicate an acting object of the time-frequency resource determined according to the first parameter and the second parameter; thus, rate matching can be flexibly performed on all or part of the designated downlink channels, downlink signals, uplink channels or uplink signals.
In some embodiments, the method further comprises any one of the following receiving steps:
receiving a first configuration parameter and the third parameter, or receiving a first configuration parameter number and the third parameter; wherein the first configuration parameters include: the first parameter and the second parameter; therefore, when the terminal determines the first resource set according to the first parameter, the second parameter and the third parameter, the first parameter, the second parameter and the third parameter are indicated at different levels, and signaling overhead is saved.

Thus, the first parameter needs to occupy 273 bits to indicate information (1).
The information (2) is a bitmap of RBG level.
Accordingly, if the first parameter is used to indicate the bitmap of the RBG level, a bit of 1in the bitmap indicates that the UE should perform rate matching in the corresponding resource block according to the symbol indicated by the second parameter (A bit in the bitmap set to 1indicates that the UE shall apply rate matching in the resource blocks within the corresponding RBG in accordance with the symbols indicated by second parameter).
The information (3) is a bitmap of BWP level.
Accordingly, if the first parameter is used to indicate the bitmap of the BWP level, the first parameter indication overhead is reduced. Bits of 1in the bitmap indicate that the UE should rate match in the corresponding resource block according to the symbols indicated by the second parameter (A bit in the bitmap set to 1indicates that the UE shall apply rate matching in the resource blocks within the corresponding RBG in accordance with the symbols indicated by second parameter).
The information (4) is a bitmap of a Subband level.
Correspondingly, if the first parameter is used for indicating the bitmap of the Subband level, the indication overhead of the first parameter is further reduced. Bits of 1in the bitmap indicate that the UE should rate match in the corresponding resource block according to the symbols indicated by the second parameter (Abit in the bitmap set to 1indicates that the UE shall apply rate matching in the resource blocks within the corresponding subband in accordance with the symbols indicated by second parameter).
If the first parameter is used for indicating the information (2), the information (3) or the information (4), the indication information cost of the first parameter is reduced along with the increase of the frequency domain indication granularity.
The information (5) is at least one first value.
In some embodiments, the first value may be a resource indicator value (Resource Indication Value, RIV).
In some embodiments, a starting RB (starting resource block, rb_start) offset and a continuously allocated RB length (a length in terms of contiguously allocated resource blocks, l_rbs) may be determined from the first value.
In some embodiments, the first value may be represented by v 1.
Compared with the bitmap indication mode, the resource indication value can further reduce the first parameter indication overhead. The following examples are given for the first value indicating manner to reduce instruction overhead:
if the first parameter is used for indicating the information (2), the information (3) or the information (4), the indication information cost of the first parameter is reduced along with the increase of the frequency domain indication granularity.
Note that in fig. 6B, time-frequency resource sets a and B occupy a continuous segment of frequency domain resources, while time-frequency resource set C occupies 2 continuous segments of frequency domain resources.
If the first parameter is used for indicating the information (5), namely when the first parameter adopts a first value indicating mode, only one first value is required to be indicated for the time-frequency resource sets A and B; for the time-frequency resource set C, 2 first values need to be indicated.
Taking an indication method of the time-frequency resource sets A and B as an example, only one first value is adopted, and the first value v1 is determined as follows:
if it isV1=a1 (L RBs -1)+RB start ；
Otherwise, v1=a1 (A1-L RBs +1)+(A1-1-RB start )。
Wherein A1 is a positive integer. RB (radio bearer) start More than or equal to 0, and/or, 0 < L RBs ≤A1-RB start 。
The first valued bit number may be determined according to equation (1):
wherein,is the number of RBs included in BWP.
Alternatively, A1 may be determined based on the maximum number of RBs within the channel (channel) bandwidth, which is sometimes referred to as the maximum transmission bandwidth allocationPut (The maximum transmission bandwidth configuration), marked as N RB . That is, a1=n RB 。
Table 1 shows N at different channel bandwidths and subcarrier spacings (SCS) in some embodiments RB And (5) configuration.
Table 1: n (N) RB Maximum transmission bandwidth configuration (Maximum transmission bandwidth configuration N) RB )
In some embodiments, a=n when the channel bandwidth is equal to 100MHz and the subcarrier spacing is equal to 30kHz RB =273. In response to this, the control unit,
as described above, for the time-frequency resource set a or B in fig. 6B, when the first parameter is used for the indication information (1), i.e., the bitmap of the RB level, 273 bits are required to be used for indicating the first parameter. And when the first parameter is used for indicating the first value, that is, the first parameter may indicate a section of continuous frequency domain resource, only 16 bits need to be used. Therefore, compared with the bitmap indication mode, the first value indication mode can obviously reduce the indication signaling overhead of the first parameter.
In some embodiments, the method may be based on RB start And L RBs A second set of RBs is determined and, accordingly, the UE should apply rate matching in the respective second set of RBs according to the symbols indicated by the second parameter (the UE shall apply rate matching in the resource blocks within the corresponding second set of RBs in accordance with the symbols indicated by second parameter).
The information (6) is at least one seventh parameter comprising a starting RB (starting resource block, RB) start ) Offset and successively allocated RB length (a length in terms of contiguously allocated resource blocks, L RBs )。
The information (7) is a third value combination number indication (combinatorial index).
In some embodiments, the third value combination count indication may be understood as: the third value may be a combination number indication.
In some embodiments, as shown in the time-frequency resource set C in fig. 6b, the first resource set is two consecutive segments of frequency-domain resources in the frequency domain, where the first parameter may also indicate the starting RB position and the ending RB position of each segment of frequency-domain resources in the form of a combination number.
In some embodiments, the third value may be represented by v 2.
In some embodiments, the first set of RBs and the second set of RBs having consecutively allocated RBs may be determined from a third value. Wherein the starting RBG number (starting RBG index) of the first RB set is s 0 Ending RBG number (ending RBG index) as s 1 -1; the starting RBG number of the second RB set is s 2 Ending RBG number s 3 -1; the third value v2 may be determined according to equation (2):
wherein m=4, n is a positive integer.
In some embodiments of the present invention, in some embodiments,wherein C is an integer. In some embodiments, c=1.
In some embodiments, the number of bits of the third value v2 may be determined according to equation (3):
wherein,for the number of RBs included in the UL bandwidth, P is the number of RBs included in the RBG. In some embodiments, n=n RB /P。
In other embodiments, n=n RB +C, wherein C is an integer. In some embodiments, c=1.
The third valued bit number may be determined according to equation (4):
Wherein,the calculation method of (2) can be referred to as formula (5):
illustratively, when n=n RB +1, and N RB When the value of =273,
/>
compared with the first parameter adopting a bitmap indication mode, the 273bit indication mode is needed, the first parameter adopting the third value combination number indication mode only needs to adopt 28bit indication mode, and the indication signaling overhead of the first parameter is reduced.
For the set of time-frequency resources C in fig. 6b, the first set of resources is two consecutive segments of frequency domain resources in the frequency domain.
When the first parameter is used for the indication information (1), i.e., the bitmap of the RB level, 273 bits are required to be used for the indication of the first parameter.
When the first parameter is used for indicating the information (5), 2 first values need to be indicated. As shown in the description in the preceding section information (5), each first value needs to occupy 16 bits, and therefore, the first parameter needs to be indicated with 16×2=32 bits in total.
When the first parameter is used for indicating the information (7), namely, adopting a combination number indicating mode, the first parameter needs to be indicated by 28 bits.
It can be seen that, in order to indicate the first resource set, similar to the time-frequency resource set C in fig. 6b, which is formed by two segments of continuous frequency-domain resources in the frequency domain, the indication signaling overhead of the first parameter can be further reduced by adopting the third value combination number indication manner for the first parameter.
In some embodiments, the time-frequency resource of the first resource set may be a portion of the bitmap of the RB level indicated by the first parameter, where the dimension corresponding to the bit indicated as 1 crosses the dimension corresponding to the bit indicated as 1 in the bitmap of the symbol level indicated by the second parameter.
In some embodiments, the UE may apply rate matching (the UE shall apply rate matching in the resource blocks within the union of the corresponding the first RB set and the second RB set in accordance with the symbols indicated by second parameters) in corresponding frames of a union of the first RB set and the second RB set according to the symbols indicated by the second RB set.
It will be appreciated that when the bitmap indication manner is adopted, the first parameter may be used to indicate not only the frequency domain resources with smaller granularity (such as RB level and/or RBG level), but also the frequency domain resources with larger granularity (such as BWP level and/or Subband level). With the increase of the indication granularity, the bit number for indicating the frequency domain resource is reduced, so that the signaling overhead can be reduced.
Further, if the first resource set is a segment of continuous frequency domain resources in the frequency domain (e.g., the time-frequency resource set a in fig. 6 b), the first parameter may further indicate the first value or the initial RB offset and the continuously allocated RB length. Therefore, only the initial RB position and the RB number of a section of continuous frequency domain resource are required to be indicated, and the rate matching mode of each RB is not required to be indicated one by one like a bitmap indication method, so that signaling indication overhead can be obviously reduced.
Furthermore, if the first resource set is two consecutive segments of frequency domain resources (e.g., the time-frequency resource set C in fig. 6 b) in the frequency domain, the first parameter may further indicate the start RB position and the end RB position of each segment of frequency domain resources in the form of a combination number, which may further significantly reduce signaling indication overhead compared to the first value indication manner.
The second parameter is used to determine time domain resources of the first set of resources. In some embodiments, the second parameter is used to indicate any one of the following information (8) to (13):
the information (8) is a symbol-level bitmap.
Accordingly, if the second parameter is used to indicate a bitmap at the symbol level, wherein a bit of 1 in the bitmap indicates that the UE is to rate match around the symbol (It indicates with a bit set to 1that the UE shall rate match around the corresponding symbol). In bitmaps, a bit is set to 1, sometimes referred to as the bit is set to true.
In particular, the information (8) indicates the use of each symbol in the N slots (slots) in the form of a bitmap. Note that for the normal CP configuration, 14 symbols are included in each slot. For the extended CP configuration, 12 symbols are included in each slot. Taking the normal CP configuration as an example, in order to indicate the use of each symbol in N slots (slots), the information (8) needs to be used: 14 x n bits.
In one embodiment, N is a time domain repeating pattern, and N is in units of time slots.
Illustratively, as shown in fig. 3, slots #0 to #4 can be regarded as one slot period, i.e., at this time, n=5, and the second parameters are required to be used in common: 5 x 14 = 70 bits.
The information (9) is a bitmap and a time domain repetition pattern at the symbol level.
In the information (9), the bitmap at the symbol level indicates the use of each symbol in the N slots (slots). Wherein n=1, or n=2.
And determining the service condition of each symbol in one time domain repetition period by combining the time domain repetition modes.
Accordingly, the time domain repetition pattern is used to indicate the repetition characteristics (Atime domain repetition pattern at which the pattern defined by first parameter and symbol level bitmap recurs) of the pattern determined from the first parameter and symbol level bitmap in the time domain.
In one embodiment, the bitmap at the symbol level indicates the rate matching manner of each symbol in a single slot, and the time domain repeating pattern indicates that one or some slots in a period of time employ the rate matching manner indicated by the bitmap at the symbol level. For example, the time domain repetition pattern is in the form of bitmap, [0 0 1 0 1], which means that every 5 slots have repetition periods, the 3 rd and 5 th slots use the rate matching method indicated by the bitmap at the symbol level. At this time, the UE repeats a slot pattern determined from two parameters, namely, a bitmap and a time domain repetition pattern at a symbol level (This slot pattern repeats itself continuously).
At this time, the second parameter is required to be used in common: and 14 x n+p bits, wherein the bitmap at the symbol level indicates the usage of each symbol in the N slots (slots), and the time domain repetition pattern indicates that each certain or some slots in the time domain period consisting of P slots adopts the rate matching manner indicated by the bitmap at the symbol level.
Illustratively, as shown in fig. 3, slots #0 to #4 may be regarded as one slot period, i.e., p=5 at this time. Let n=2, the second parameter needs to be used in common: 14 x n+p=14 x 2+5=33 bits.
The information (9) indication mode can significantly reduce signaling indication overhead compared to the information (8), but the information (9) indication mode reduces indication flexibility, i.e. the information (9) indication mode requires that some time slots indicated by the time domain repetition mode adopt the same rate matching mode determined according to bitmap indication of the symbol level.
The information (10) is a first period and at least one second value.
The set of time-frequency resources a and C as shown in fig. 6B comprises only 1 segment of contiguous time-domain resources in the time domain, while the set of time-frequency resources B comprises 2 segments of contiguous time-domain resources in the time domain.
When the indication mode shown in the information (10) is adopted, a second value is needed to be adopted for indicating the time-frequency resource sets A and C; and 2 second values are needed to indicate the time-frequency resource set B.
In some embodiments, the second value may be a start and length indication value (Start and Length Indicator Value, SLIV).
In some embodiments, a start symbol (S) and an allocation length (the allocation length) L may be determined based on the second value.
In some embodiments, S, L is in symbols.
In some embodiments, the first period is in units of time slots; in other embodiments, the first period is in symbols.
In some embodiments, a first symbol set (symbols) may be determined from the starting symbol S and the allocation length L.
In some embodiments, the UE should rate match around the symbols indicated by the second parameter (the UE shall apply rate matching around the corresponding symbols indicated by second parameter).
Still further, the UE should rate match the associated first set of symbols for the period indicated by the first period (the UE shall apply rate matching around the corresponding first set of symbols in period indicated by first period).
The above "UE should perform rate matching on the related first symbol set in the period indicated by the first period" may also be described as: the UE will perform rate matching with respect to the first symbol set determined according to the starting symbol S and the allocation length L with the first period as a repetition period, which is not limited in this embodiment.
In some embodiments, if period P is the number of symbols included in the first period. Then:
when the first period is in symbol, p=the first period;
when the first period takes slot as a unit, if the first period is a normal CP, p=14;
when the first period is in slot units, p=12 if it is an extended CP.
In some embodiments, the second value may be represented by v 3.
In some embodiments, ifV3=p (L-1) +s;
otherwise, v3=p (P-l+1) + (P-1-S).
In some embodiments, S.gtoreq.0, 0 < L.ltoreq.P-S.
In some embodiments, the number of bits of the second value may be determined according to equation (6)
Illustratively, as shown in fig. 3, slots #0 to #4 may be regarded as one slot period, i.e., the first period=5 slots, then p=5×14=70; at this time, the process is performed,
obviously, on the premise that the time domain part of the first resource set only comprises 1 segment of continuous time domain resource, the indication mode shown by the information (10) provides the maximum indication flexibility, namely, can indicate all time domain resource combination modes (namely, can indicate all combinations of the starting symbol S and the allocation length L).
To obtain the same flexibility of indication, the information (8) needs to use 70 bits.
The information (9) requires the use of 33 bits and the same flexibility of indication as the information (10) method is not achieved yet.
Thus, the method shown in information (10) has the lowest indication signaling overhead when the time domain part of the first set of resources comprises only 1 segment of contiguous time domain resources.
-information (11) about a first period and at least one eighth parameter, said eighth parameter comprising: a start symbol S and an allocation length L.
In some embodiments, the specific application scenario of the information (11) is similar to the information (10), except that in the information (10), the second value calculated according to the starting symbol S and the allocation length L is indicated, and in the information (11), the original starting symbol S and the allocation length L are directly indicated.
The information (12) is a second value, a first period and a first offset;
another method for partitioning the set of time-frequency resources is given in fig. 6 c.
The set E of time-frequency resources shown comprises only 1 segment of contiguous time-domain resources in the time domain, whereas the set D of time-frequency resources comprises 2 segments of contiguous time-domain resources in the time domain.
For indicating the set of time-frequency resources E, it is sufficient to take a period and 1 second value.
However, to indicate the set of time-frequency resources D, to avoid using 2 second indications, it is also possible to consider indicating the second value and the first offset to further reduce the overhead.
In some embodiments, the first offset is in symbols.
In some embodiments, the number of bits of the first offset may be determined according to equation (7):
in some embodiments, the first offset may be denoted by v4, where the range of values of the first offset is: v4 is more than or equal to 0 and P-1 is more than or equal to 1.
The UE first calculates a starting symbol S and an allocation length L according to the second value.
In some embodiments, the UE will rate match slot x with slot P as the repetition period, where x satisfies the following relationship of equations (8) and (9):
x＝(i+o)mod P (8)
S≤i≤S+L-1 (9)
where o may be determined from the first offset. o is an integer.
Illustratively, as shown in fig. 6, in order to indicate the time domain resources of the time-frequency resource set D (each including 2 consecutive time domain resources, two time domain resources occupy 46 symbols and 2 symbols respectively) in 6c, the indication symbol set is needed: (0, 3 x 14+4-1) and (5 x 14-2,5 x 14-1), can be configured:
S＝0、o＝P-2＝68、L＝46+2＝48、P＝70；
then i is more than or equal to 0 and less than or equal to 47; when x= (i+o) mod p= (i+68) mod 70, the value range of x is (68, 69), (0, 1,., 45), i.e. the required set of set symbols is: (0, 3 x 14+4-1) and (5 x 14-2,5 x 14-1).
At this time, it can be determined according to the formula (6)
At this time, the second value and the first offset together need to use 12+7=19bit.
And when the time-frequency resource set D is indicated by using 2 second values, 2×12=24 bits need to be used.
It can be seen that, when the set of time-frequency resources to be indicated includes 2 consecutive time-domain resources in the time domain, the indication manner shown in the information (12) can further reduce the signaling indication overhead.
The information (13) is a start symbol S, an allocation length L, a first period and a first offset.
It can be appreciated that when the bitmap indication manner is adopted, the second parameter can indicate the rate matching condition of each symbol by symbol, which has the greatest indication flexibility, but the corresponding signaling overhead is also the greatest.
Further, if the first set of resources is a segment of consecutive time domain resources in the time domain during the first period (e.g., the time-frequency set of resources a in fig. 6 b), the second parameter may further indicate the second value or the initial symbol offset and the continuously allocated symbol length. At this time, only the initial symbol position and the number of symbols of a section of continuous time domain resource are required to be indicated, and the rate matching mode of each symbol is not required to be indicated one by one like the bitmap indication method, so that the signaling indication overhead can be obviously reduced.
Further, if the first set of resources includes multiple continuous time domain resources in the time domain in the first period (e.g., the first set of resources is the set D of time-frequency resources in fig. 6 c), then the two continuous time domain resources in the first period can be "spliced" into one continuous time domain resource by applying the first offset, so that the two continuous time domain resources can be indicated by using the indication parameters (i.e., the start symbol S and the allocation length L) of the one continuous time domain resource, and signaling indication overhead can be significantly reduced.
The third parameter is used to determine at least one of a transmission direction, at least one channel, and at least one signal of the first set of resources.
In this embodiment, "the third parameter is used to determine the transmission direction of the first resource set", which may also be described as: the third parameter is a transmission direction indication, etc., which is not limited in this embodiment.
In some embodiments, the transmission direction may be uplink or downlink.
In some embodiments, if the transmission direction is downlink, REs associated with the first set of resources are not available for all downlink channels and/or all downlink signals.
In some embodiments, if the transmission direction is downlink, REs associated with the first set of resources are not available for part of the downlink channel and/or part of the downlink signal.
In this embodiment, the UE may determine, based on at least one of a correlation convention, a pre-convention, other network configurations, and a network indication, which downlink channels and/or downlink signals are unavailable to REs associated with the first resource set, which is not limited in this embodiment.
In some embodiments, if the transmission direction is uplink, the REs associated with the first set of resources are not available for all uplink channels and/or all uplink signals.
In some embodiments, if the transmission direction is uplink, the REs associated with the first set of resources are not available for a portion of the uplink channel and/or a portion of the uplink signal.
In this embodiment, the UE may determine, based on a relevant rule, a pre-appointment, other network configurations, and/or a network indication, which uplink channels and/or uplink signals are unavailable to REs associated with the first resource set, which is not limited in this embodiment.
In this embodiment, the "third parameter is used to determine at least one channel", which can also be described as: the third parameter includes at least one channel indication, etc., which is not limited in this embodiment.
Illustratively, "the third parameter is used to determine { PDSCH, PUSCH }" may also be described as: the third parameter includes { PDSCH indication, PUSCH indication }.
For example, if the third parameter is used to determine { PDSCH, PUSCH }, the third parameter is used to indicate that REs associated with the first set of resources are not available for PDSCH and PUSCH transmissions.
In this embodiment, the "third parameter is used to determine at least one signal", and may also be described as: the third parameter includes at least one signal indication, etc., which is not limited in this embodiment.
Illustratively, "the third parameter is used to determine { CSI-RS }", which can also be described as: the third parameter includes { CSI-RS indication }.
Illustratively, if the third parameter is used to determine { CSI-RS }, the third parameter is used to indicate that REs associated with the first set of resources are not available for CSI-RS transmission.
It may be appreciated that, in this embodiment, the third parameter may be used to determine a transmission direction and/or indicate an acting object of a time-frequency resource (which may be referred to as a rate matching mode or Rate Match Pattern in some embodiments) determined according to the first parameter and the second parameter, when the transmission direction is uplink, the terminal may perform rate matching resource configuration for an uplink signal and/or a channel, and when the transmission direction is downlink, the terminal may perform rate matching resource configuration for a downlink signal and/or a channel, so that in this embodiment, according to the network configuration, rate matching for all or part of specified downlink channels, downlink signals, uplink channels, or uplink signals may be flexibly implemented.
When the UE determines the first resource set according to the first parameter, the second parameter and the third parameter, the first parameter, the second parameter and the third parameter have two indication modes. One way of indication may be: the first parameter and the second parameter are indicated in the same layer as the third parameter. In this way, the integrity of each IE is advantageously enhanced. Another indication may be: the first parameter and the second parameter are indicated at different levels than the third parameter. In this way, the third parameter can indicate the transmission directions of the first parameters and the second parameters only by 1 time, thereby saving the signaling overhead.
In some embodiments, the sending the network configuration information to the terminal includes any of the following steps S1 to S4:
step S1, a network device sends a first configuration parameter and the third parameter, or sends a first configuration reference number (index) and the third parameter; wherein the first configuration parameters include: the first parameter and the second parameter.
Correspondingly, the terminal receives the first configuration parameter and the third parameter, or receives the first configuration parameter number and the third parameter.
In some embodiments, the first configuration parameters include: the first parameter and the second parameter; accordingly, the terminal may determine the first resource set according to the first configuration parameter (i.e., the first parameter and the second parameter) and the third parameter. In this embodiment, the first parameter and the second parameter are indicated at different levels than the third parameter.
In some embodiments, the first configuration parameters include: the first parameter and the second parameter; the terminal may determine the first resource set according to the first configuration parameter number and the third parameter.
Step S2, the network equipment sends a second configuration parameter or a second configuration parameter number; wherein the second configuration parameters include the third parameter and at least one of the first configuration parameters.

In some embodiments, the terminal may determine the first resource set according to the fourth configuration parameter or the fourth configuration parameter number. In this embodiment, the first parameter and the second parameter are indicated at the same layer as the third parameter.
It may be appreciated that in the present embodiment, the first resource set may be determined according to at least one of the first parameter, the second parameter, and the third parameter.
In a sub-band full duplex scenario, the base station side sub-band configuration is fixed, or semi-static, so in order to save signaling overhead, the configuration of the first resource set need not be dynamically indicated by downlink control information (Downlink Control Information, DCI).
In addition, in the full duplex scene of the sub-band, there are both uplink sub-band and downlink sub-band, so in order to improve the signaling indication efficiency and reduce the signaling indication overhead, the terminal can activate the uplink rate matching resource set and the downlink rate matching resource set according to the MAC CE signaling.
In some embodiments, the terminal may activate or deactivate at least two of the first resource sets according to MAC CE signaling; wherein,
REs associated with at least one of said at least two of said first resource sets are not available for downlink channels, and/or downlink signaling;
and REs associated with at least one of said at least two of said first resource sets are not available for uplink channels, and/or uplink signaling.
In some embodiments, at least one resource set of "RE associated with at least one of the at least two first resource sets is not available for downlink channel and/or downlink signaling" is different from at least one resource set of "RE associated with at least one of the at least two first resource sets is not available for uplink channel and/or uplink signaling".
Illustratively, rate Match Pattern of DL and UL are included in Rate Match Pattern Group and are activated simultaneously by MAC CE.
Illustratively, as shown in fig. 6b and 7b, the UE needs to activate at least one set of uplink rate matching resources and at least one set of downlink rate matching resources simultaneously.
In some embodiments, the network device sends network configuration information to the terminal, the network configuration information being used to determine the subband configuration. Fig. 8 is a schematic diagram of a subband according to an embodiment of the present application.
In some embodiments, the first set of resources is a union of at least one downlink sub-band and at least one first state sub-band; or, the first resource set is a union of at least one uplink sub-band and at least one first state sub-band.
In some embodiments, the network configuration information includes at least one of: fourth, fifth and sixth parameters; wherein,
the fourth parameter is used for determining the frequency domain resource of the subband configuration;
the fifth parameter is used for determining time domain resources of the subband configuration;

In some embodiments, "the subbands include: at least one of the downlink sub-band, the uplink sub-band, the first state sub-band, is equivalent to: the subband configuration includes: at least one of a downlink sub-band, an uplink sub-band and a first state sub-band.
In some embodiments, the uplink transmission may include: uplink channel transmission and/or uplink signal transmission; the downlink transmission may include a downlink signal and/or a downlink channel transmission.

Note that in some embodiments, the uplink sub-band, the downlink sub-band, and the first state sub-band have only frequency domain properties, i.e., only define the use cases of frequency domain resources; in yet other embodiments, the uplink sub-band, the downlink sub-band, and the first state sub-band have time-frequency resource properties, i.e., the use of two-dimensional time-frequency resources is defined at the same time.
When the uplink sub-band, the downlink sub-band, and the first state sub-band have only frequency domain properties, in some embodiments, the first state sub-band is referred to as a Guard band (Guard band), or frequency domain Guard band, or frequency domain isolation band;
