In order to better understand the technical solutions disclosed in the embodiments of the present disclosure, the technical solutions according to the embodiments of the present disclosure will be described in detail below.

License-free frequency band

The unlicensed spectrum is a shared spectrum. Communication devices in different communication systems may use the spectrum as long as they meet regulatory requirements set by the country or region for the spectrum and do not need to apply for a proprietary spectrum grant to the government.

In order to enable friendly coexistence of various communication systems using unlicensed spectrum for wireless communication in the spectrum, some countries or regions stipulate regulatory requirements that must be met using unlicensed spectrum. For example, communication devices follow the principle of "Listen Before Talk" (LBT), that is, the device needs to perform channel sensing Before transmitting a signal on the channel. The device can perform signaling only if the LBT result indicates that the channel is free; otherwise, the device cannot perform signal transmission. To ensure fairness, once a device successfully occupies a Channel, the transmission duration may not exceed the Maximum Channel Occupancy Time (MCOT).

On an unlicensed carrier, for a channel occupancy time obtained by a base station, the base station may share the channel occupancy time with a UE for transmitting an uplink signal or an uplink channel. In other words, when the base station shares its own channel occupying time with the UE, the UE may obtain the channel using the LBT mode having a higher priority than that used by the UE itself, thereby obtaining the channel with a greater probability.

NR-U interleaving structure

In the unlicensed band at 5 ghz, the regulations provide that if a transmitter wants to operate on a transmission in the channel, the transmission must occupy at least 80% of the channel bandwidth. In view of this limitation, a New Radio-Unlicensed (NR-U) decides to adopt an interleaving structure for two uplink channel transmissions, which are a Physical Uplink Control Channel (PUCCH) and a PUSCH. Each interlace will have a particular number of Physical Resource Blocks (PRBs). There are M PRBs further spaced apart between each successive PRB pair. For example, in the case of a 20Mhz bandwidth and 30KHz subcarrier spacing, 1 interlace has 10 or 11 PRBs and M ═ 5, as shown in fig. 2.

Broadband operation

In NR-U Wideband (WB) operation, a BS and a UE may operate in a wider band consisting of a plurality of sub-bands. Since NR version 15(rel.15) has defined the bandwidth part (BWP) concept, the UE can be configured with an active BWP containing multiple sets of RBs in the context of NR-U WB operations. The gNB may assign multiple sets of RBs to the UE for uplink transmission (e.g., PUSCH transmission).

In release 16, PUSCH transmission may be configured to use an interleaving structure. In addition, the active uplink bandwidth portion may include more than one set of RBs. When Downlink Control Information (DCI) schedules PUSCH transmission, the DCI needs to indicate a selected interlace and a selected RB set. In addition, the DCI for scheduling may have formats 0_0 and 0_ 1. How to design the indication field to include these resource selection indications in both DCI formats remains an unresolved issue. Methods for solving this problem are active in the present invention.

It should be noted that the technical solution according to the embodiments of the present disclosure is applicable to a mobile telecommunication system which is a 5G mobile network including a 5G NR access network. The technical solution of the present disclosure is applicable to NR (NR-U) in unlicensed spectrum. The present disclosure is applicable to other mobile networks, in particular to mobile networks of any next generation cellular network technology (6G, etc.).

Fig. 3 is a schematic flow chart diagram of a communication method according to an embodiment of the present disclosure. As shown in fig. 3, the communication method includes

operations

301 and 302.

In operation 301, a network device sends first information to a UE, and the UE receives the first information sent by the network device.

In some embodiments of the present disclosure, the network device may be a base station, such as a next generation node B (gNB).

In a possible embodiment, the first information is carried in Downlink Control Information (DCI) or Random Access Response (RAR).

In a possible implementation, the first information is Frequency Domain Resource Assignment (FDRA) information.

In some embodiments of the present disclosure, the first information is used by the UE to determine frequency domain resources for uplink transmission, as shown in operation 302.

In operation 302, the UE determines frequency domain resources for uplink transmission based on the first information.

In some embodiments of the present disclosure, the first information includes first indication information and/or second indication information. Specifically, the first indication information is used to indicate one or more selected interlaces, and the second indication information is used to indicate one or more selected Resource Block (RB) sets. Specific embodiments of the first indication information and the second indication information are described below.

1) First indication information

In some embodiments of the present disclosure, the first indication information has M bits, where M is a positive integer; the value of M is determined based on the number of interlaces included in the interlace set, which is determined based on the Subcarrier Spacing (SCS) of the active uplink bandwidth part BWP.

A1) In a possible implementation, the M bits represent a first bitmap, each bit of which corresponds to an interleaving index, the value of the bit indicating whether an interleaving corresponding to the interleaving index corresponding to the bit is selected.

Further optionally, M is M, where M is the number of interlaces included in the interlace set.

For example, for M-3, the 3 bits represent the first bitmap { b1, b2, b3}, where b1 corresponds to interlace index #1, b2 corresponds to interlace index #2, and b3 corresponds to interlace index # 3. When the value of bi (i ═ 1, 2, 3) is 1, it indicates that the interlace corresponding to interlace index # i is selected; and when the value of bi (i ═ 1, 2, 3) is 0, it indicates that the interlace corresponding to the interlace index # i is not selected.

B1) In a possible implementation, the value of the M bits is used to indicate that the interlace corresponding to the interlace index indicated by the value of the M bits is selected.

Herein, when the M bits have different values, the interleaving indexes indicated by the values of the M bits are different.

For example, when M is 2, the M bits are b1b2, then b1b2 00 indicates interlace index #1, b1b2 01 indicates interlace index #2, b1b2 10 indicates interlace index #3, and b1b2 11 indicates interlace index # 4.

In some embodiments of the present disclosure, it is preferred,

where m is the number of interlaces included in the interlace set.

In the example, if the SCS of the active uplink BWP is 30KHz, the value of M is 5.

In the example, if the SCS of the active uplink BWP is 15KHz, the value of M is 6.

2) Second indication information

In some embodiments of the present disclosure, the second indication information has N bits, N being a positive integer, wherein the value of N is determined based on the number of RB sets included in the active uplink BWP.

A2) In a possible implementation, the N bits represent a second bitmap, each bit of which corresponds to an RB set index, the value of the bit being used to indicate whether the RB set corresponding to the RB set index corresponding to the bit is selected.

Further optionally, N ═ N, where N is the number of RB sets included in the active uplink BWP.

For example, for N-3, the 3 bits represent a second bitmap { a1, a2, a3}, where a1 corresponds to RB set index #1, a2 corresponds to RB set index #2, and a3 corresponds to RB set index # 3. When the value of ai (i ═ 1, 2, 3) is 1, it indicates that an RB set corresponding to RB set index # i is selected; and when the value of ai (i ═ 1, 2, 3) is 0, it indicates that the RB set corresponding to RB set index # i is not selected.

B2) In a possible implementation, the value of the N bits is used to indicate that the RB set corresponding to the RB set index indicated by the value of the N bits is selected.

For example, when N is 2, the N bits are a1a2, then a1a2 00 indicates RB set index #1, a1a2 01 indicates RB set index #2, a1a2 10 indicates RB set index #3, and a1a 2-11 indicates RB set index # 4.

In some embodiments of the present disclosure, it is preferred,

where n is the number of sets of RBs included in the active uplink BWP.

In the above technical solution, according to some embodiments, the one or more selected RB sets are determined as at least one default RB set for active uplink BWP. In a possible embodiment, the at least one default RB set includes one RB set corresponding to one RB set index. In another embodiment, the at least one default RB set includes at least two RB sets corresponding to at least two consecutive RB set indices.

In some embodiments of the present disclosure, the default RB set is configured through Radio Resource Control (RRC) signaling; or the default RB set is configured by System Information (SI); or the default RB set is predefined.

In some embodiments of the present disclosure, in the case where the first information is carried in DCI, the DCI may have one of the following features.

I) DCI is received by a UE in Common Search Space (CSS); or the DCI is received by the UE in a UE-specific Search Space (USS).

It should be noted that in case DCI is received by the UE in the USS, the selected set of RBs in the above technical solution may not be the default set of RBs for the active uplink BWP.

II) the DCI is used to schedule PUSCH transmission in one cell.

III) DCI has DCI Format 0_0

The technical solution of the embodiments of the present disclosure is described in detail below with reference to specific application examples.

When the gNB schedules the UE to transmit a PUSCH transmission, the gNB will send DCI containing information about the resource allocation for the PUSCH transmission. One information about resource allocation is Frequency Domain Resource Assignment (FDRA). If the UE is provided by a higher layer with the higher layer parameter userintertracepkusch-Common-r 16, the frequency domain resource assignment corresponds to an indication for the selected interlace and RB set, i.e., the UE may be assigned one or more interlaces on one or more RB sets.

The FDRA information may have a first indication field for indicating a selected interlace for PUSCH transmission. In NRU systems, the number of interlaces depends on the subcarrier spacing of the active bandwidth part. There are 10 interlaces for subcarrier spacing (SCS) 15KHz and 5 interlaces for SCS 30 KHz. Thus, this indication field will be used to indicate the selected interlace when the SCS of the active BWP is configured. For SCS 15KHz, a bitmap of 5 bits may be used to indicate the interleaving index, e.g. the ordering of 5 bits may be such that the Least Significant Bit (LSB) represents the interleaving index 0 and up to the Most Significant Bit (MSB) represents the interleaving index 4, or the opposite ordering. The advantage is that the bitmap can flexibly select the interleaving index.

For SCS 15KHz, since there are more interleaves (i.e., 10 interleaves), a bitmap of 10 bits similar to the case of SCS 30KHz may be used, but bit overhead increases. An alternative solution is to restrict the selected interlace index to be contiguous. With such a limitation, only the need exists

One bit (i.e., 6 bits).

The FDRA information may also have a second indication field for indicating the selected RB set in which the PUSCH is transmitted. For an active uplink bandwidth part (UL BWP), a maximum of 5 RB sets may be configured. The second indication field may be n bits, where n is the number of RB sets configured for active UL BWP. Alternatively, the set of selected RBs may be limited to be contiguous such that the bits needed to indicate become N bits, where

Embodiments of FDRA information are shown in the following various scenarios.

Case 1DCI format 0_1 FDRA information

When the UE is in RRC connected mode, the UE will receive DCI formats 0_1 and 0_0 for PUSCH scheduling. For DCI format 0_1, since DCI format 0_1 may only be received in the UE-specific search space (USS), the UE knows that DCI can only be assigned to the UE if DCI is detected. Thus, for DCI format 0_1, the FDRA information should include a first indication field for interlace selection and a second indication field for RB set selection.

Case 2 FDRA information of DCI format 0_0

On the other hand, DCI format 0_0 may be received in a UE-specific search space (USS) and a Common Search Space (CSS). When DCI format 0_0 is received in the USS, the FDRA information may include a first indication field for interlace selection and a second indication field for RB set selection. But when DCI format 0_0 is received in CSS, the DCI overhead should remain independent of the corresponding UE active UL BWP configuration (e.g., different number of sets of RBs in active UL BWP) since other UEs will also detect this search space, in which case the FDRA information of DCI format 0_0 will not contain the second indication field, but only the first indication field for interlace selection. The UE determines the selected set of RBs as a pre-configured set of RBs in an RRC configuration or predefined in a specification. The advantage is that DCI format 0_0 size can be kept unchanged in CSS; an advantage is that once DCI format 0_0 is transmitted in CSS to schedule PUSCH, no set of RBs can be dynamically selected.

Case 3 FDRA information for DCI format 0_0

A very simple solution for DCI format 0_0 is to include a first indication field for interlace selection and a second indication field for RB set selection in both USS and CSS.

FDRA information in case 4RAR

In the initial access phase, the UE receives UL grant scheduling information in the RAR, which includes FDRA information. At this stage, the UE does not receive RRC configuration for active uplink BWP and RB set configuration. Thus, if the system information is configured to use interleaving with a parameter (e.g., userintertracepsusch-Common-r 16 or userintertraceccucch-Common-r 16), the FDRA is only the first indication field for interleaving selection. In this case, the PUSCH will use the selected interlace and the selected RB set is determined as the default RB set, which is the initial uplink bandwidth portion itself. The initial UL BWP is configured in system information (SIB 1).

Fig. 4 is a first schematic structural diagram of a communication device provided in an embodiment of the present disclosure. The device is applied to the UE. As shown in fig. 4, the communication apparatus includes a receiving unit 401 and a determining unit 402.

The receiving unit 401 is configured to receive first information transmitted by a network device.

The determining unit 402 is configured to determine frequency domain resources for uplink transmission based on the first information.

In a possible embodiment, the first information comprises first indication information indicating the one or more selected interlaces.

In a possible implementation, the first indication has M bits, M being a positive integer,

herein, the value of M is determined based on the number of interlaces included in the interlace set, which is determined based on the subcarrier spacing (SCS) of the active uplink bandwidth part BWP.

In a possible implementation, the M bits represent a first bitmap, each bit of which corresponds to an interleaving index, the value of the bit indicating whether an interleaving corresponding to the interleaving index corresponding to the bit is selected.

In a possible implementation, the value of the M bits is used to indicate that the interlace corresponding to the interlace index indicated by the value of the M bits is selected.

In a possible embodiment of the method according to the invention,

where m is the number of interlaces included in the interlace set.

In a possible implementation, the value of M is 5 if the SCS of the active uplink BWP is 30 KHz.

In a possible implementation, the value of M is 6 if the SCS of the active uplink BWP is 15 KHz.

In a possible embodiment, the first information includes second indication information indicating one or more selected Resource Block (RB) sets.

In a possible implementation, the second indication information has N bits, N being a positive integer.

Herein, the value of N is determined based on the number of RB sets included in the active uplink BWP.

In a possible implementation, the N bits represent a second bitmap, each bit of which corresponds to an RB set index, the value of the bit being used to indicate whether the RB set corresponding to the RB set index corresponding to the bit is selected.

In a possible implementation, the value of the N bits is used to indicate that the RB set corresponding to the RB set index indicated by the value of the N bits is selected.
