Description
BACKGROUND OF DISCLOSURE
1. Field of the Disclosure
The present disclosure relates to the field of communication systems, and more particularly, to an apparatus and a method of wireless communication, which can provide a good communication performance and/or high reliability.
2. Description of the Related Art
An unlicensed spectrum is a shared spectrum. Communication equipments in different communication systems can use the unlicensed spectrum as long as the unlicensed meets regulatory requirements set by countries or regions on a spectrum. There is no need to apply for a proprietary spectrum authorization from a government.
In order to allow various communication systems that use the unlicensed spectrum for wireless communication to coexist friendly in the spectrum, some countries or regions specify regulatory requirements that must be met to use the unlicensed spectrum. For example, a communication device follows a listen before talk (LBT) procedure (also called a channel access procedure) , that is, the communication device needs to perform a channel sensing before transmitting a signal on a channel. When an LBT outcome illustrates that the channel is idle, the communication device can perform signal transmission; otherwise, the communication device cannot perform signal transmission. In order to ensure fairness, once a communication device successfully occupies the channel, a transmission duration cannot exceed a maximum channel occupancy time (MCOT) .
On an unlicensed carrier, for a channel occupation time obtained by a base station, it may share the channel occupation time to a user equipment (UE) for transmitting an uplink signal or an uplink channel. In other words, when the base station shares its own channel occupancy time with the UE, the UE can use an LBT mode with higher priority than that used by the UE itself to obtain the channel, thereby obtaining the channel with greater probability. An LBT is also called a channel access procedure. UE performs the channel access procedure before the transmission, if the channel access procedure is successful, i.e. the channel is sensed to be idle, the UE starts to perform the transmission. If the channel access procedure is not successful, i.e. the channel is sensed to be not idle, the UE cannot perform the transmission.
In a new radio unlicensed (NRU) system, when a UE tries to connect to a network, the UE will go through an initial access phase. During the initial access phase, the UE will need to feedback hybrid automatic repeat request acknowledgment (HARQ-ACK) to the network about successfulness of physical downlink sharing channel (PDSCH) reception. This feedback is transmitted in an interlaced physical uplink control channel (PUCCH) resource. The way of determining the interlaced PUCCH resource cannot reuse the same mechanism as being defined for the licensed band.
Therefore, there is a need for an apparatus (such as a user equipment (UE) and/or a base station) and a method of wireless communication, which can solve issues in the prior art, provide PUCCH resource determination, provide a good communication performance, and/or provide high reliability.

In some embodiments, the PUCCH resource is used for a PUCCH transmission. In some embodiments, the UE 10 determines the PUCCH resource from a PUCCH resource set, wherein the PUCCH resource set comprises sixteen PUCCH resources corresponding to PUCCH resource indexes from 0 to 15. In some embodiments, the UE 10 determines the PUCCH resource from the PUCCH resource set by determining the PUCCH resource index. In some embodiments, the first information indicates a row index of a table, wherein the table comprises a PUCCH format, a first symbol, a duration, a PRB offset
and a set of initial cyclic shift indexes of the PUCCH resource set. In some embodiments, the table is pre-defined. In some embodiments, the row index is 3 corresponding to at least one of the followings: the first symbol is 10; the PUCCH format is PUCCH format 1; the duration is of 4 symbols; the PRB offset is zero; or the set of initial cyclic shift indexes comprises 0 and 6.

In some embodiments, the PUCCH resource indication field indicates a value Δ
PRI for the PUCCH resource indication. In some embodiments, the UE 10 determines the PUCCH resource index r
PUCCH by
Δ
PRI, where N
CCE is a number of control channel elements (CCEs) in a control resource set (CORESET) of a physical downlink control channel (PDCCH) (PDCCH) reception with a DCI format, n
CCE,
0 is an index of a first CCE for the PDCCH reception. In some embodiments, the first information comprises a first higher layer parameter. In some embodiments, the second information comprises a second higher layer parameter. In some embodiments, the second information comprises useInterlacePUCCH-Common-r16.

In some embodiments, the method of the UE 10 determining the OCC index for the PUCCH resource comprises determining an OCC with index 0 used for the PUCCH resource index r

PUCCH greater than or equal to 10. In some embodiments, the UE determines the interlace index for the PUCCH resource as an interlace index m, where
and M is a number of interlaces. In some embodiments, M is 5 or 10. In some embodiments, the UE 10 determines an initial cyclic shift index in the set of initial cyclic shift indexes as r
PUCCHmodN
CS, where N
CS is a total number of initial cyclic shifts indexes in the set of initial cyclic shift indexes.
Some examples provide methods of determining an interlaced PUCCH resource during an initial access phase for NRU system.
Example:
In this example, during an initial access phase, a UE 10 illustrated in FIG. 1 receives SIB1 information wherein if a higher layer parameter such as useInterlacePUCCH-Common-r16 is enabled and a higher layer parameter such as PUCCH-Configcommon selects row index 3 of a table 1 below.
Table 1: PUCCH resource sets
Then, FIG. 1 illustrates that in some embodiments, the UE 10 will understand that an interlaced PUCCH format 1 (PF1) is used and the PF1 has symbol length 4. Moreover, once the UE 10 receives a downlink (DL) assignment, the UE 10 will derive a PUCCH resource index (r
PUCCH) as
where N
CCE is a number of CCEs in a CORESET, n
CCE, 0 is a first CCE index of the received PDCCH, and Δ
PRI∈ [0, 7] is a PUCCH resource indication received from a DCI format 1_0. Thus, the derived r
PUCCH has a range of 0 to 15. PUCCH resource is composed of three parameters, i.e. initial cyclic shift (initial CS) . For row index 3 of the above table 1, the initial CS are {0, 6} ; the interlace index, for 30 khz subcarrier spacing (SCS) , the interlace index has range {0, 1, 2, 3, 4} ; the OCC index, which has two possible indices (1
st OCC index and 2
nd OCC index) . Therefore, once the UE 10 derives r
PUCCH, it can find the PUCCH resource such that: r
PUCCH=0 and {initial CS=0, interlace0, OCC1} ; r
PUCCH=1 and {initial CS=6, interlace0, OCC1} ; r
PUCCH=2 and {initial CS=0, interlace1, OCC1} ; r
PUCCH=3 and {initial CS=6, interlace1, OCC1} ; r
PUCCH=4 and {initial CS=0, interlace2, OCC1} ; r
PUCCH=5 and {initial CS=6, interlace2, OCC1} ; r
PUCCH=6 and {initial CS=0, interlace3, OCC1} ; r
PUCCH=7 and {initial CS=6, interlace3, OCC1} ; r
PUCCH=8 and {initial CS=0, interlace4, OCC1} ; r
PUCCH=9 and {initial CS=6, interlace4, OCC1} ; r
PUCCH=10 and {initial CS=0, interlace0, OCC2} ; r
PUCCH=11 and {initial CS=6, interlace0, OCC2} ; r
PUCCH=12 and {initial CS=0, interlace1, OCC2} ; r
PUCCH=13 and {initial CS=6, interlace1, OCC2} ; r
PUCCH=14 and {initial CS=0, interlace2, OCC2} ; and/or r
PUCCH=15 and {initial CS=6, interlace2, OCC2} . In some embodiments, OCC1 and OCC2 are the first OCC index and the second OCC index, respectively. For row index 3, OCC1=OCC index 0, with orthogonal sequence
and
OCC2=OCC index 1, with orthogonal sequence
and
For SCS=15khz, the interlace index has range of {0, 1, 2, 3, 4, 5, 6, 7, 8, 9} . Therefore, in 15khz SCS case, the PUCCH resource index (r
PUCCH ) to PUCCH resource mapping is: r
PUCCH=0 and {initial CS=0, interlace0, OCC1} ; r
PUCCH=1 and {initial CS=6, interlace0, OCC1} ; r
PUCCH=2 and {initial CS=0, interlace1, OCC1} ; r
PUCCH=3 and {initial CS=6, interlace1, OCC1} ; r
PUCCH=4 and {initial CS=0, interlace2, OCC1} ; r
PUCCH=5 and {initial CS=6, interlace2, OCC1} ; r
PUCCH=6 and {initial CS=0, interlace3, OCC1} ; r
PUCCH=7 and {initial CS=6, interlace3, OCC1} ; r
PUCCH=8 and {initial CS=0, interlace4, OCC1} ; r
PUCCH=9 and {initial CS=6, interlace4, OCC1} ; r
PUCCH=10 and {initial CS=0, interlace5, OCC1} ; r
PUCCH=11 and {initial CS=6, interlace5, OCC1} ; r
PUCCH=12 and {initial CS=0, interlace6, OCC1} ; r
PUCCH=13 and {initial CS=6, interlace6, OCC1} ; r
PUCCH=14 and {initial CS=0, interlace7, OCC1} ; and/or r
PUCCH=15 and {initial CS=6, interlace7, OCC1} .
Thus, only 1 OCC index is enough to have 16 different PUCCH resources.
Example:
In this example, during the initial access phase, the UE 10 as illustrated in FIG. 1 receives SIB1 information wherein a higher layer parameter such as useInterlacePUCCH-Common-r16 is enabled and a higher layer parameter such as PUCCH-Configcommon selects row index 7 of a table 2 below.
Table 2: PUCCH resource sets
Thus, the UE 10 will understand that an interlaced PUCCH format 1 (PF1) is used and the PF1 has symbol length 10.Moreover, once the UE 10 receives a DL assignment, the UE 10 will derive a PUCCH resource index (r
PUCCH ) as
where N
CCE is the number of CCEs in the CORESET, n
CCE, 0 is the first CCE index of the received PDCCH, and Δ
PRI∈ [0, 7] is the PUCCH resource indication received from the DCI format 1_0. Thus, the derived r
PUCCH has a range of 0 to 15. The PUCCH resource is composed of three parameters, i.e. initial cyclic shift (initial CS) . for row index 3 of the above table 2, the initial CS are {0, 6} ; the interlace index, for 30 khz SCS the interlace index has range {0, 1, 2, 3, 4} ; the OCC index, which has two possible indices (1
st OCC index and 2
nd OCC index) . Therefore, once the UE 10 derives r
PUCCH, it can find the PUCCH resource such that: r
PUCCH=0 and {initial CS=0, interlace0, OCC1} ; r
PUCCH=1 and {initial CS=6, interlace0, OCC1} ; r
PUCCH=2 and {initial CS=0, interlace1, OCC1} ; r
PUCCH=3 and {initial CS=6, interlace1, OCC1} ; r
PUCCH=4 and {initial CS=0, interlace2, OCC1} ; r
PUCCH=5 and {initial CS=6, interlace2, OCC1} ; r
PUCCH=6 and {initial CS=0, interlace3, OCC1} ; r
PUCCH=7 and {initial CS=6, interlace3, OCC1} ; r
PUCCH=8 and {initial CS=0, interlace4, OCC1} ; r
PUCCH=9 and {initial CS=6, interlace4, OCC1} ; r
PUCCH=10 and {initial CS=0, interlace0, OCC2} ; r
PUCCH=11 and {initial CS=6, interlace0, OCC2} ; r
PUCCH=12 and {initial CS=0, interlace1, OCC2} ; r
PUCCH=13 and {initial CS=6, interlace1, OCC2} ; r
PUCCH=14 and {initial CS=0, interlace2, OCC2} ; and/or r
PUCCH=15 and {initial CS=6, interlace2, OCC2} . In some embodiments, OCC1 and OCC2 are the first OCC index and the second OCC index, respectively.
For row index 3, OCC1=OCC index 0, with orthogonal sequence
and
OCC2 can be any one of the following: OCC2= OCC index 1, with orthogonal sequence and
OCC2= OCC index 2, with orthogonal sequence and
OCC2= OCC index 3, with orthogonal sequence and
3 1 4 2] ; and/or OCC2= OCC index 4, with orthogonal sequence and
The selection of OCC2 can be following an ascending order with regards to OCC1, i.e. in this example, OCC2 is OCC index 1. Alternatively, OCC2 can follow a descending order with regards to OCC1, i.e. OCC2 is OCC index 4. This solution is simple and no additional signalling is needed. Alternatively, OCC2 can be configured in SIB1 (e.g. in PUCCH-Configcommon information element (IE) ) . This SIB1 configuring OCC2 will allow the network to have flexibility to select the second OCC index. Advantageously, to achieve a similar flexibility OCC1 can be configured in SIB1, and OCC2 can follow ascending order or descending order with regards to OCC1.
In some embodiments, for SCS=15 khz, the interlace index has range of {0, 1, 2, 3, 4, 5, 6, 7, 8, 9} . Therefore, in 15khz SCS case, the PUCCH resource index (r
PUCCH ) to PUCCH resource mapping is: r
PUCCH=0 and {initial CS=0, interlace0, OCC1} ; r
PUCCH=1 and {initial CS=6, interlace0, OCC1} ; r
PUCCH=2 and {initial CS=0, interlace1, OCC1} ; r
PUCCH=3 and {initial CS=6, interlace1, OCC1} ; r
PUCCH=4 and {initial CS=0, interlace2, OCC1} ; r
PUCCH=5 and {initial CS=6, interlace2, OCC1} ; r
PUCCH=6 and {initial CS=0, interlace3, OCC1} ; r
PUCCH=7 and {initial CS=6, interlace3, OCC1} ; r
PUCCH=8 and {initial CS=0, interlace4, OCC1} ; r
PUCCH=9 and {initial CS=6, interlace4, OCC1} ; r
PUCCH=10 and {initial CS=0, interlace5, OCC1} ; r
PUCCH=11 and {initial CS=6, interlace5, OCC1} ; r
PUCCH=12 and {initial CS=0, interlace6, OCC1} ; r
PUCCH=13 and {initial CS=6, interlace6, OCC1} ; and r
PUCCH=14 → {initial CS=0, interlace7, OCC1} ; and/or r
PUCCH=15 and {initial CS=6, interlace7, OCC1} .
Thus, only 1 OCC index is enough to have 16 different PUCCH resources.
Example:
During the initial access phase, the UE 10 as illustrated in FIG. 1 receives SIB1 information, wherein if useInterlacePUCCH-Common-r16 is enabled and PUCCH-Configcommon selects row index 11 of a table 3 below.
Table 3: PUCCH resource sets
Thus, the UE 10 will understand that the interlaced PUCCH format 1 (PF1) is used and the PF1 has symbol length 14. Moreover, once the UE 10 receives a DL assignment, the UE 10 will derive the PUCCH resource index (r
PUCCH ) as r
PUCCH=0 and {initial CS=0, interlace0, OCC1} ; r
PUCCH=1 and {initial CS=6, interlace0, OCC1} ; r
PUCCH=2 and {initial CS=0, interlace1, OCC1} ; r
PUCCH=3 and {initial CS=6, interlace1, OCC1} ; r
PUCCH=4 and {initial CS=0, interlace2, OCC1} ; r
PUCCH=5 and {initial CS=6, interlace2, OCC1} ; r
PUCCH=6 and {initial CS=0, interlace3, OCC1} ; r
PUCCH=7 and {initial CS=6, interlace3, OCC1} ; r
PUCCH=8 and {initial CS=0, interlace4, OCC1} ; r
PUCCH=9 and {initial CS=6, interlace4, OCC1} ; r
PUCCH=10 and {initial CS=0, interlace0, OCC2} ; r
PUCCH=11 and {initial CS=6, interlace0, OCC2} ; r
PUCCH=12 and {initial CS=0, interlace1, OCC2} ; r
PUCCH=13 and {initial CS=6, interlace1, OCC2} ; r
PUCCH=14 and {initial CS=0, interlace2, OCC2} ; and/or r
PUCCH=15 and {initial CS=6, interlace2, OCC2} . In some embodiments, OCC1 and OCC2 are the first OCC index and the second OCC index, respectively. For row index 3, OCC1=OCC index 0, with orthogonal sequence
and
OCC2 can be any one of the following: OCC2= OCC index 1, with orthogonal sequence
and
OCC2= OCC index 2, with orthogonal sequence
and
OCC2= OCC index 3, with orthogonal sequence
and
OCC2= OCC index 4, with orthogonal sequence
and
OCC2= OCC index 5, with orthogonal sequence
and
OCC2= OCC index 6, with orthogonal sequence
and
The selection of OCC2 can be following an ascending order with regards to OCC1, i.e. in this example, OCC2 is OCC index 1. Alternatively, OCC2 can follow a descending order with regards to OCC1, i.e. OCC2 is OCC index 4. This solution is simple and no additional signalling is needed. Alternatively, OCC2 can be pre-defined for a specific OCC index in specification or the OCC index can be configured in SIB1 (e.g. in PUCCH-Configcommon IE) . This SIB1 configuring OCC2 will allow the network to have flexibility to select the second OCC index. Advantageously, to achieve a similar flexibility OCC1 can be configured in SIB1, and OCC2 can follow ascending order or descending order with regards to OCC1. Alternatively, OCC1 and OCC2 can be pre-defined and coded in a table 4 such as the modified table below, where OCC1=x, OCC2=y. These indexes can be set differently for table row indexes 3, 7, 11 (i.e. x1≠x2≠x3, y1≠y2≠y3) or identically (i.e. x1=x2=x3, y1=y2=y3) . Note that it is also doable that the OCC indexes column only indicates OCC2 index by fixing OCC1 index always 0; or the other way around.
Table 4: PUCCH resource sets
For SCS=15 khz, the interlace index has a range of {0, 1, 2, 3, 4, 5, 6, 7, 8, 9} . Therefore, in 15khz SCS case, the r
PUCCH to PUCCH resource mapping is: r
PUCCH=0 and {initial CS=0, interlace0, OCC1} ; r
PUCCH=1 and {initial CS=6, interlace0, OCC1} ; r
PUCCH=2 and {initial CS=0, interlace1, OCC1} ; r
PUCCH=3 and {initial CS=6, interlace1, OCC1} ; r
PUCCH=4 and {initial CS=0, interlace2, OCC1} ; r
PUCCH=5 and {initial CS=6, interlace2, OCC1} ; r
PUCCH=6 and {initial CS=0, interlace3, OCC1} ; r
PUCCH=7 and {initial CS=6, interlace3, OCC1} ; r
PUCCH=8 and {initial CS=0, interlace4, OCC1} ; r
PUCCH=9 and {initial CS=6, interlace4, OCC1} ; r
PUCCH=10 and {initial CS=0, interlace5, OCC1} ; r
PUCCH=11 and {initial CS=6, interlace5, OCC1} ; r
PUCCH=12 and {initial CS=0, interlace6, OCC1} ; r
PUCCH=13 and {initial CS=6, interlace6, OCC1} ; r
PUCCH=14 and {initial CS=0, interlace7, OCC1} ; and/or r
PUCCH=15 and {initial CS=6, interlace7, OCC1} .
Thus, only 1 OCC index is enough to have 16 different PUCCH resources.
Example:

In summary, in some embodiments , amethod, performed by a user equipment (UE) , for determining an interlaced PUCCH resource during an initial access phase, comprises the steps of: receiving a row index indication from SIB1; determining a PUCCH format, either format 0 or format 1, based on the indicated row index and a first table (PUCCH_tab) ; receiving a downlink control indicator (DCI) that assigns a PDSCH transmission; deriving the interlaced PUCCH resource index (r_PUCCH) based on PUCCH resource indicator (PRI) and a physical resource where the DCI is received; mapping the r_PUCCH to interlaced PUCCH resource, where interlaced PUCCH resource is composed of : an initial cyclic shift (initial CS) , interlace index, first symbol position, when PUCCH format is 0; or an initial CS, interlace index, orthogonal cover code (OCC) index, when PUCCH format is 1. Advantageously, the mapping from r_PUCCH to interlaced PUCCH resources, in an ascending order of r_PUCCH, follows: for PUCCH format 0: initial CS first, interlace index second and first symbol position last; for PUCCH format 1: initial CS first, interlace index second and OCC index last. Advantageously, initial CS candidates are given in the indicated row index of PUCCH_tab, and wherein when mapping from r-PUCCH to interlaced PUCCH resources, the initial CS follows a determined order of the initial CS values. It could be for example an ascending order, i.e. from smallest to largest, or a descending order. Advantageously, the interlace indexes are given by the subcarrier spacing as follow: for 15khz, there are 10 interlace indexes (from 0 to 9) ; and for 30Khz, there are 5 interlace indexes (from 0 to 4) ; and wherein when mapping from r-PUCCH to interlaced PUCCH resources, the interlace index follows a determined order of the interlace indexes. Advantageously, the first symbol positions are given in the indicated row index of PUCCH_tab such that for PUCCH format 0, the first symbol positions are 9 and 12 and wherein, when mapping from r-PUCCH to interlaced PUCCH resources, first symbol positions follows a determined order. Advantageously, two OCC indexes are selected from indexes 0 to 6 when PUCCH format is 1 and the number of initial CS candidates is two; otherwise one OCC index is selected. Advantageously, the first OCC and the second OCC indexes are pre-defined. Advantageously, the second OCC index is incremented or decremented by 1with respect to the first OCC index. Advantageously, the first OCC index and/or the second OCC index are given in PUCCH_tab. Advantageously, when selecting two OCC indexes, the first OCC and/or the second OCC indexes can be configured in SIB1. Advantageously, the PUCCH_tab is pre-defined.
