[0021] For clarity of description, the present disclosure will be described in the context of 3GPP communication systems (e.g., LTE and NR), which should not be construed as limiting the spirit of the present disclosure. LTE refers to technology beyond 3GPP TS 36.xxx version 8.

[0029] Figure 1 The radio frame structure for NR is shown.

[0030] In NR, UL and DL transmissions are configured on a frame basis. Each radio frame has a length of 10ms and is divided into two 5ms half-frames. Each half-frame is divided into five 1ms subframes. A subframe is divided into one or more time slots, and the number of time slots in a subframe depends on the subcarrier spacing (SCS). Depending on the cyclic prefix (CP), each time slot includes 12 or 14 OFDM (A) symbols. When a normal CP is used, each time slot includes 14 OFDM symbols. When an extended CP is used, each time slot includes 12 OFDM symbols. Symbols may include OFDM symbols (or CP-OFDM symbols) and SC-FDMA symbols (or discrete Fourier transform-extended-OFDM (DFT-s-OFDM) symbols).

[0031] Table 1 exemplarily shows that the number of symbols per slot, the number of slots per frame, and the number of slots per subframe vary according to the SCS in the normal CP case.

[0032] [Table 1]

[0035] *N frame，u slot : Number of time slots in a frame

[0036] *N subframe，u slot : Number of time slots in a subframe

[0037] Table 2 shows that the number of symbols per slot, the number of slots per frame, and the number of slots per subframe vary according to SCS in the case of extended CP.

[0038] [Table 2]

[0039] SCS(15*2^u) <![CDATA[N slot symb ]]> <![CDATA[N frame，u slot ]]> <![CDATA[N subframe，u slot ]]> 60KHz(u=2) 12 40 4

[0040] In the NR system, different OFDM(A) parameter sets (e.g., SCS, CP length, etc.) may be configured for multiple cells aggregated for one UE. Therefore, the (absolute time) duration of a time resource (e.g., a subframe, a time slot, or a transmission time interval (TTI)) (referred to as a time unit (TU) for convenience) consisting of the same number of symbols may be configured differently between the aggregated cells.

[0041] In NR, various parameter sets (or SCS) can be supported to support various 5th generation (5G) services. For example, for an SCS of 15kHz, wide areas in the traditional cellular band can be supported, while for an SCS of 30kHz or 60kHz, dense urban areas, lower latency, and wide carrier bandwidth can be supported. For an SCS of 60kHz or higher, bandwidths greater than 24.25kHz can be supported to overcome phase noise.

[0042] The NR frequency band may be defined by two types of frequency ranges FR1 and FR2. FR1 and FR2 may be configured as described in Table 3 below. FR2 may be millimeter wave (mmW).

[0043] [Table 3]

[0044] Frequency range specification Corresponding frequency range Subcarrier spacing FR1 450MHz-7125MHz 15, 30, 60kHz FR2 24250MHz-52600MHz 60, 120, 240kHz

[0045] Figure 2 The resource grid during the duration of one time slot is shown.

[0046] A time slot includes multiple symbols in the time domain. For example, a time slot includes 14 symbols in the normal CP case and 12 symbols in the extended CP case. A carrier includes multiple subcarriers in the frequency domain. A resource block (RB) can be defined by multiple (e.g., 12) consecutive subcarriers in the frequency domain. Multiple RB interleavings (referred to as interleavings) can be defined in the frequency domain. Interleaving m∈{0, 1, ..., M-1} can be composed of (common) RBs{m, M+m, 2M+m, 3M+m, ...}. M represents the number of interleavings. A bandwidth part (BWP) can be defined by multiple consecutive (physical) RBs ((P)RBs) in the frequency domain and corresponds to a parameter set (e.g., SCS, CP length, etc.). A carrier can include up to N (e.g., five) BWPs. Data communication can be performed in an active BWP, and only one BWP can be enabled for a UE. Each element in a resource grid can be referred to as a resource element (RE), to which a complex symbol can be mapped.

[0047] In a wireless communication system, a UE receives information from a BS in a downlink (DL), and the UE transmits information to the BS in an uplink (UL). The information exchanged between the BS and the UE includes data and various control information, and there are various physical channels / signals according to the type / purpose of the information exchanged therebetween. A physical channel corresponds to a set of resource elements (REs) that carry information from a higher layer. A physical signal corresponds to a set of REs that are used by the physical layer but do not carry information from a higher layer. The higher layer includes a medium access control (MAC) layer, a radio link control (RLC) layer, a packet data convergence protocol (PDCP) layer, a radio resource control (RRC) layer, and the like.

[0048] DL physical channels include physical broadcast channel (PBCH), physical downlink shared channel (PDSCH) and physical downlink control channel (PDCCH). DL physical signals include DL reference signal (RS), primary synchronization signal (PSS) and secondary synchronization signal (SSS). DL RS includes demodulation reference signal (DM-RS), phase tracking reference signal (PT-RS) and channel state information reference signal (CSI-RS). UL physical channels include physical random access channel (PRACH), physical uplink shared channel (PUSCH) and physical uplink control channel (PUCCH). UL physical signals include UL RS. UL RS includes DM-RS, PT-RS and sounding reference signal (SRS).

[0049] Figure 3 The structure of a self-contained time slot is illustrated.

[0050] In the NR system, a frame has a self-contained structure in which a DL control channel, DL or UL data, a UL control channel, etc. can all be included in one time slot. For example, the first N symbols in a time slot (hereinafter, the DL control region) can be used to send a DL control channel, and the last M symbols in a time slot (hereinafter, the UL control region) can be used to send a UL control channel. N and M are integers greater than or equal to 0. The resource region (hereinafter, the data region) between the DL control region and the UL control region can be used for DL ​​data transmission or UL data transmission. For example, the following configuration can be considered. List the various parts in chronological order.

[0051] In the present disclosure, a base station (BS) may be, for example, a gNode B (gNB).

[0052] Resource configuration in Network Energy Saving (NES) mode

[0053] The above content can be applied in combination with the method proposed in the present disclosure (described later). Alternatively, the content can illustrate the technical features of the method proposed in the present disclosure.

[0054] In addition, the following methods can be equally applied to the above-mentioned NR system (licensed band) or shared spectrum. Therefore, it is obvious that in order to implement the technical concept of the present disclosure in the corresponding system, the terms, expressions and structures in this document can be modified to be suitable for the system.

[0055] For energy saving at the BS, a network energy saving (NES) mode (i.e., a mode for energy saving at the BS) may be defined. A BS operating in the NES mode may reduce its power consumption by suspending (maintaining) DL or UL transmission during a specific period of time or limiting transmission and reception operations in a specific frequency band. In the present disclosure, the NES mode may refer to an operating mode of a BS and / or UE defined / configured / indicated for such a purpose. In addition, in the present disclosure, the operating mode of a UE (or cell) that is not configured with the NES mode (or a configuration based on the NES) is referred to as a non-NES mode to distinguish the operating mode from the NES mode.

[0056] The NES mode may be maintained only for a specific period of time. In a proposal described later, the period of time during which the BS operates in the NES mode is referred to as the NES duration. The NES mode may be valid only for specific frequency resources. In a proposal described later, the frequency resources corresponding to the NES mode are referred to as NES bands.

[0057] The NES mode may be configured by the BS through separate higher layer signaling or higher layer configuration. Alternatively, the NES mode may be dynamically configured to the BS / UE through other control channels (e.g., based on DCI indications) or data channels (e.g., PDSCH, PUSCH). During the NES mode, the BS may turn on / off specific times, frequencies, antenna resources, etc., and may not send / receive related data channels, control channels, or control signals. During the NES mode, the UE may operate by expecting that specific times / frequencies / antenna resources will be turned on / off and related channels / signals will not be sent.

[0058] For UEs with NES mode defined / configured, a BWP for NES mode (NES BWP) can be defined / configured. The NES BWP can be set as a separate BWP that operates only in NES mode. In this case, the BWP for non-NES mode may not be defined or deactivated. Alternatively, a specific (single) BWP may be configured differently for NES mode and non-NES mode. For example, a specific BWP may be set to an NES BWP during an NES duration and to a different BWP during other durations. The configuration method and constraints of the NES BWP may be defined / configured separately from the conventional BWP. For example, in the NES BWP, PDCCH monitoring may not be performed, but non-periodic CSI-RS signals and reports may be configured. As another example, the periodicity of the periodic CSI-RS may be reinterpreted in the NES BWP.

[0059] Unique BWP switching operations in NES mode can be defined. For example, in conventional BWP switching configuration / operation, when a BWP other than the default BWP is the active BWP, a timer is set. If the timer expires, the current active BWP is switched to inactive, and the default BWP is restored to the new active BWP. On the other hand, in NES mode, if the timer expires, the current active BWP can be switched to inactive, and the dormant BWP or NES BWP can be switched to a new active BWP. Alternatively, if the timer expires, the current active BWP can be switched to inactive, and the default BWP can be switched to a new active BWP (as in conventional operation). If DL / UL transmission is not scheduled / configured in the default BWP within a certain period of time, the default BWP can be switched to inactive, and the dormant BWP or NES BWP can be switched to a new active BWP.

[0060] The proposed methods described later can be applied independently under the conditions described for each method or configured only during the NES duration. Alternatively, the methods can be applied only in the NES band.

[0061] In the proposed method described later, operating in non-NES mode means any NR configuration / operation that is not configured for NES (e.g., configuration / operation specified in Rel-15, Rel-16, or Rel-17 NR specifications). In the proposed method described later, the operation of switching to NES mode can only be applied to UE / cell configured for NES. In addition, NES mode is not limited to a specific configuration or operation method. That is, NES mode can be any configuration or operation method defined / configured for NES. In the proposed method described later, switching to NES mode can also be understood as switching to NES BWP.

[0062] In the proposed method described later, the expression "configure specific parameters (or operations)" may be understood to mean that the parameters (or operations) are configured for any cell, for a specific UE, for a configured cell for a specific UE, for a configured DL (or UL) BWP for a specific cell, or for an active DL (or UL) BWP for a specific cell.

[0063] For ease of explanation, in the present disclosure, DL BWP and / or UL BWP may be referred to as BWP for short. Unless otherwise specified, DL BWP and / or UL BWP may refer to BWP (configured for UE) or active BWP (among configured BWP).

[0064] In the proposed method described later, a MAC control element (CE) or DCI (e.g., a MAC CE or DCI that triggers BWP switching or configuration / activation / deactivation specific operations) may be transmitted in a UE-specific, UE group-common, or cell-specific manner. The DCI may be scrambled with an RNTI configured in a UE-specific, UE group-common, or cell-specific manner and then transmitted. A MAC CE may be transmitted on a PDSCH scheduled by a DCI that is scrambled with an RNTI configured in a UE-specific, UE group-common, or cell-specific manner.

[0065] [1] Method for configuring activation / deactivation of a secondary cell (SCell) through a group common (GC) MAC CE

[0066] [1-1] In Rel-15 / 16 / 17, SCell activation / deactivation (for each UE) can be configured by a MAC CE dedicated to the corresponding UE. In this case, the MAC CE command can consist of 1 octet or 4 octets (with a logical channel identifier (LCID) size). If the number of SCells configured for the UE is 7 or less, 1 octet is used. If the number of SCells configured for the UE is 7 or more, 4 octets are used. In this case, each bit of the octet (each C field included in the octet) represents the activation or deactivation of each SCell.

[0067] Table 4 extracted from 3GPP TS 38.321 represents the prior art. Figure 4 The MAC CE for SCell activation / deactivation is illustrated and consists of 1 octet. Figure 5 The MAC CE for SCell activation / deactivation is illustrated, which consists of 4 octets.

[0068] [Table 4]

[0069]

[0070]

[0071] Referring to Table 4, the conventional SCell activation / deactivation MAC CE includes a C field and an R field. Figure 4 and Figure 5 , each C field consists of 1 bit. Each C field is associated with index i, and index i corresponds to the index (index i) of the SCell configured for the UE. If the value of the C field is 1, the SCell with the corresponding index is activated, and if the value of the C field is 0, the SCell with the corresponding index is deactivated. For example, when Figure 4 When the SCell activation / deactivation MAC CE in the MAC CE consists of bits 10011010, if the UE receives the MAC CE, the SCells with index 1, index 3, index 4 and index 7 can be activated, and the SCells with index 2, index 5 and index 6 can be deactivated. The R field is always set to 0 and does not affect the activation / deactivation of the SCell. In section [1], the bits constituting the MAC CE may refer to the C field.

[0072] In order to use such UE-specific (or UE-dedicated) MAC CE, when a specific cell is configured as an SCell (with different cell indices) for multiple UEs, a separate MAC CE command needs to be sent to each UE in order to activate or deactivate the cell across all UEs.

[0073] [1-2] For UEs configured with NES mode, SCell activation / deactivation through MACCE can be configured and / or indicated to multiple UEs in a GC manner. Therefore, it is expected that the amount of MAC CE commands sent by the BS can be reduced. However, when a specific cell is configured as an SCell for multiple UEs, the cell index for the specific cell may be different for each UE. For example, for cell #A, cell #B, and cell #C defined on a specific frequency band (or frequency), when UE #1 is configured with 2 cells = {cell #A, cell #B} as SCells, and UE #2 is configured with 2 cells = {cell #B, cell #C} as SCells, the cell index for cell #B configured for UE #1 can be 2, and the cell index for cell #B configured for UE #2 can be 1. Therefore, when sending MAC CE in a GC manner, a method may be required to specify specific cells for different UEs.

[0074] [1-3] Regarding the problem mentioned in [1-2], when sending MAC CE in GC mode, the method of indicating a specific cell to different UEs (to ensure common understanding) can be determined according to one of the following methods (in a combination of two or more). Each of the following proposed methods can be particularly applied to a UE configured with NES mode. However, the present disclosure is not limited to this.

[0075] -Method 1: For N cells (which can be configured for multiple UEs), the GC index can be configured through RRC signaling. For example, the GC index can be index #1,..., index #N. When some M (<=N) cells are configured as SCells for UEs, the GC index can be used as an index for the SCell. When the GC MAC CE indicates the GC index, the activation / deactivation of a specific cell can be configured and / or indicated to multiple UEs.

[0076] ■ In this case, information about N cells (eg, GC index) may be configured to each UE through UE-specific RRC signaling (before receiving the GC MAC CE).

[0077] ■ In this case, by indicating the GC index using the GC MAC CE, the activation or deactivation of a specific cell can be configured and / or indicated in a GC manner.

[0078] ■Implementation method) The GC indexes for 4 cells = {cell #A, cell #B, cell #C, cell #D} are defined as #1, #2, #3 and #4 respectively. Each UE receives information via UE-specific RRC signaling. The UE can be configured with some of the cells and their indexes. UE#1 has {cell #A, cell #B} configured as SCell index #1 and #2, UE#2 has {cell #B, cell #D} configured as SCell index #2 and #4, and UE#3 has {cell #D} configured as SCell index #4. In this case, when the BS indicates the activation or deactivation of the cell with index #4 through the GC MAC CE, (UE#1 can ignore the GCMAC CE and) UE#2 and UE#3 can apply the corresponding operation to cell #D.

[0079] -Method 2: For N cells (which may be configured for multiple UEs), the mapping information between each bit (or field) of the GC MAC CE and the SCell index of each UE may be configured through RRC signaling. Subsequently, the activation / deactivation of a specific cell for multiple UEs may be configured and / or indicated through the GC MAC CE.

[0080] ■ In this case, the mapping information may be configured to each UE via UE-specific RRC signaling (before receiving the GC MAC CE).

[0081] ■ In this case, the mapping information can be configured in the form of a bitmap.

[0082] ◆Implementation method) Assume that among 4 cells = {cell #A, cell #B, cell #C, cell #D}, UE#1 has {cell #A, cell #B} configured as SCell, and UE#2 has {cell #B, cell #C, cell #D} configured as SCell. If bitmap #1 = 1100 is configured for UE#1 through UE-specific RRC signaling, the UE can know that the configured SCell is the first cell and the second cell among a total of N cells. If bitmap #2 = 0111 is configured for UE#2 through UE-specific RRC signaling, the UE can know that the configured SCell is the second cell, the third cell and the fourth cell among a total of N cells. In this case, if activation / deactivation for N cells is indicated by GC MAC CE, each UE can determine which cells among the N cells are configured as SCells. For example, if "0110" is configured / indicated by GC MAC CE, UE#1 can apply the GC MAC CE indication to cell #B by performing an AND operation between "0110" and bitmap #1. Similarly, UE#2 can apply the GC MAC CE indication to cell #B and cell #C by performing an AND operation between "0110" and bitmap #2.

[0083] ■ Alternatively, mapping information may be configured based on an offset method.

[0084] ◆Implementation method) Assume that among 4 cells = {cell #A, cell #B, cell #C, cell #D}, UE#1 has {cell #A, cell #B} configured as SCell, and UE#2 has {cell #B, cell #C, cell #D} configured as SCell. If offset #1 = 0 is configured for UE#1 through UE-specific RRC signaling, the UE can know that the configured SCells are 2 cells starting from the lowest index among a total of N cells. If offset #2 = 1 is configured for UE#2 through UE-specific RRC signaling, the UE can know that the configured SCells are 3 cells starting from the second lowest index among a total of N cells. In this case, if activation / deactivation for N cells is indicated by GC MAC CE, each UE can determine which cells among the N cells are configured as SCells (for the UE). For example, if '0110' is configured / indicated by the GC MAC CE, UE#1 may apply only the first 2 bits from the left side of '0110', and UE#2 may apply only 3 bits starting from the second bit from the left side.

[0085] -Method 3: Cell indications for K UEs may be serially concatenated to form a GC MAC CE that may be configured for multiple UEs. For example, the GC MAC CE may be configured so that the indication information for each UE may be listed separately in the form of {information for UE#1, information for UE#2, ..., information for UE#N}. In this case, each UE may be assigned / configured with a corresponding bit position from the GC MAC CE (through separate RRC signaling or DCI). Upon receiving the GC MAC CE, the UE may extract and apply the configuration / indication for the cell configured for the UE based on the assigned bit position.

[0086] ■For example, assume that among 4 cells = {cell #A, cell #B, cell #C, cell #D}, UE#1 has {cell #A, cell #B} configured as SCell, and UE#2 has {cell #B, cell #C, cell #D} configured as SCell. The GC MAC CE may be configured in the form of {“activation / deactivation indication for cell #A for UE#1”, “activation / deactivation indication for cell #B for UE#1”, “activation / deactivation indication for cell #B for UE#2”, “activation / deactivation indication for cell #C for UE#2”, “activation / deactivation indication for cell #D for UE#2”} (to indicate only the cells configured for each UE). Alternatively, the GC MAC CE can be configured in the form of {"cell #A of UE#1", "cell #B of UE#1", ..., "cell #B of UE#2", "cell #C of UE#2", "cell #D of UE#2"} to indicate the total number of cells, regardless of the number of cells configured for each UE.

[0087] - Method 4: The mapping information between each bit of the GC MAC CE and the index of the SCell of each UE is configured through separate (UE-specific) RRC signaling. After receiving the GC MAC CE, the UE can determine the activation / deactivation indication for the SCell configured for the UE based on the mapping information.

[0088] ■For example, assume that among 4 cells = {cell #A, cell #B, cell #C, cell #D}, UE #1 has {cell #A, cell #B} configured as SCell, and UE #2 has {cell #B, cell #C, cell #D} configured as SCell. In this case, cell #A of UE #1 can be mapped to the first bit of GC MAC CE, cell #B of UE #1 and cell #B of UE #2 can be mapped to the second bit, cell #C of UE #2 can be mapped to the third bit, and cell #D of UE #2 can be mapped to the fourth bit. In this case, if the second bit of MAC CE configures / indicates activation or deactivation, both UE #1 and UE #2 can activate or deactivate cell #B.

[0089] ■In another example, all (or some specific) SCells configured for UE#A may be mapped to specific bits of the GC MAC CE. All (or some specific) SCells configured for UE#B may be mapped to other specific bits of the GC MAC CE. After receiving the GC MAC CE, the UE may determine whether activation or deactivation of each SCell is configured / indicated (based on the mapping relationship between the SCells configured through RRC signaling and the bits of the MAC CE).

[0090] [1-4] When the method in [1-3] is applied, each bit of the GC MAC CE may indicate a single cell or two or more cells. In this case, each UE may receive information about the cell set indicated by each bit of the GC MAC CE or the number of cells indicated by each bit through UE-specific RRC signaling.

[0091] - For example, each bit of the GC MAC CE may be provided to each UE via RRC signaling to indicate a specific cell set (eg, intra-band contiguous carriers within a specific frequency band). In this case, K different sets may be jointly activated or deactivated via K bits of the GC MAC CE.

[0092] - In another example, 1 bit of GC MAC CE may be provided to each UE through RRC signaling to indicate G neighboring cells (eg, 2 cells). In this case, K*G cells may be jointly activated or deactivated through K bits of GC MAC CE.

[0093] In this case, if the SCell for the UE is configured in a specific group (eg, a unit of a cell set or a unit of G neighboring cells), when the SCell is configured, information indicated by each bit of the GC MAC CE may be configured together.

[0094] [1-5] If the physical cell ID of each cell is directly indicated through the GC MAC CE, the activation / deactivation configuration for a specific cell can be commonly indicated for multiple UEs.

[0095] [1-6] The above-proposed method can be applied to one of the following cells.

[0096] - Option 1: The proposed method can be applied to all SCells configured (or configurable) for the UE.

[0097] - Option 2: The proposed method can be applied to a subset of all SCells configured (or configurable) for the UE.

[0098] - Option 3: The proposed method may be applied solely to a cell group (eg, a master cell group (MCG) or a secondary cell group (SCG)) to which a cell configured (or configurable) for a UE belongs.

[0099] - Option 4: The proposed method may be applied individually based on the frequency range (FR) to which the cell configured (or configurable) for the UE belongs.

[0100] - Option 5: The proposed method may be applied individually based on the type of frequency band to which a cell configured (or configurable) for a UE belongs (eg, a licensed band or an unlicensed band).

[0101] - Option 6: The proposed method may be applied to a primary cell (PCell) or a primary secondary cell (PSCell) configured (or configurable) for a UE.

[0102] ■ For example, in the method in [1-3] above, the bitmap may include PCell and SCell. Alternatively, some SCells may be replaced by PCell (or PSCell) and applied.

[0103] [1-7] The methods in [1-3] to [1-6] can also be applied to SCell activation or deactivation through GC DCI. For example, each bit of GC DCI can indicate a specific cell or a set of cells (for multiple UEs) in the same way that each bit of MAC CE (described above in method 1 or method 2 of [1-3]) indicates a specific cell. As another example, GCDCI can be configured so that activation / deactivation indications for all UEs are listed consecutively (as in method 3 of [1-3]). As another example, GC DCI can indicate a specific cell or a set of cells (for multiple UEs) based on the mapping relationship between each bit of DCI and the SCell of each UE (as in method 4 of [1-3]).

[0104] [2] Method for configuring BWP switching through GC MAC CE

[0105] [2-1]

[0106] [2-2] For UEs configured with NES mode, MAC CE-based BWP switching can be configured / indicated to multiple UEs in a GC manner. Therefore, it can be expected that the amount of MAC CE commands sent by the BS can be reduced. However, when a specific cell is configured as an SCell for multiple UEs, the cell index for the specific cell may be different for each UE. For example, for cell #A, cell #B, and cell #C defined on a specific frequency band or frequency, when UE #1 is configured with 2 cells = {cell #A, cell #B} as SCells, and UE #2 is configured with 2 cells = {cell #B, cell #C} as SCells, the cell index for cell #B configured for UE #1 can be 2, and the cell index for cell #B configured for UE #2 can be 1. Therefore, when MAC CE is sent in a GC manner, a method may be required to specify specific cells for different UEs. In addition, unlike the SCell activation / deactivation described in [1], since up to 4 BWPs can be configured for each cell, 1 or 2 bits may be required to distinguish between the 4 BWPs per cell (when configured / indicated by GC MAC CE). In the method described later, the process for mapping each bit of the MAC CE to each SCell (of a specific UE) or the process for indicating each SCell by each bit of the MAC CE can be applied to BWP switching by mapping 2 bits of the MAC CE to each cell (and / or each BWP of each cell) (of the UE) or by indicating each cell (and / or each BWP of each cell) using 2 bits of the MAC CE.

[0107] [2-3] Regarding the problem mentioned in [2-2], when sending MAC CE in GC mode, the method of indicating a specific cell to different UEs to ensure common understanding can be determined according to one of the following methods (in a combination of two or more). Each of the following proposed methods can be particularly applied to a UE configured with NES mode. However, the present disclosure is not limited to this.

[0108] -Method 1: For N cells (which can be configured for multiple UEs), the GC index can be configured through RRC signaling. For example, the GC index can be index #1,..., index #N. When some M (<=N) cells are configured as SCells for UEs, the GC index can be used as an index for the SCell. When the GC MAC CE indicates the GC index, BWP switching for a specific cell can be configured and / or indicated to multiple UEs.

[0109] ■ In this case, information about N cells (eg, GC index) may be configured to each UE through UE-specific RRC signaling (before receiving the GC MAC CE).

[0110] ■ In this case, by indicating the GC index using the GC MAC CE, BWP switching for a specific cell can be configured and / or indicated in a GC manner.

[0111] ■Implementation method) The GC indexes for 4 cells = {cell #A, cell #B, cell #C, cell #D} are defined as #1, #2, #3 and #4 respectively. Each UE receives information via UE-specific RRC signaling. The UE can be configured with some of the cells and their indexes. UE#1 has {cell #A, cell #B} configured as SCell index #1 and #2, UE#2 has {cell #B, cell #D} configured as SCell index #2 and #4, and UE#3 has {cell #D} configured as SCell index #4. In this case, when the BS indicates BWP switching for the cell with index #4 through GC MAC CE, (UE#1 can ignore GCMAC CE and) UE#2 and UE#3 can apply corresponding operations to cell #D.

[0112] -Method 2: For N cells (which may be configured for multiple UEs), the mapping information between each bit (or field) of the GC MAC CE and the SCell index of each UE may be configured through RRC signaling. Subsequently, the BWP switching of a specific cell for multiple UEs may be configured and / or indicated through the GC MAC CE.

[0113] ■ In this case, the mapping information may be configured to each UE via UE-specific RRC signaling (before receiving the GC MAC CE).

[0114] ■ In this case, the mapping information can be configured in the form of a bitmap.

[0115] ◆Implementation method) Assume that among 4 cells = {cell #A, cell #B, cell #C, cell #D}, UE#1 has {cell #A, cell #B} configured as SCell, and UE#2 has {cell #B, cell #C, cell #D} configured as SCell. If bitmap #1 = 1100 is configured for UE#1 through UE-specific RRC signaling, the UE can know that the configured SCell is the first cell and the second cell among a total of N cells. If bitmap #2 = 0111 is configured for UE#2 through UE-specific RRC signaling, the UE can know that the configured SCell is the second cell, the third cell and the fourth cell among a total of N cells. In this case, if BWP switching for N cells is indicated by GC MAC CE, each UE can determine which cells among the N cells are configured as SCells. For example, if "0110" is configured / indicated by GC MAC CE, UE#1 can apply the GC MAC CE indication to cell #B by performing an AND operation between "0110" and bitmap #1. Similarly, UE#2 can apply the GC MAC CE indication to cell #B and cell #C by performing an AND operation between "0110" and bitmap #2.

[0116] ■ Alternatively, mapping information may be configured based on an offset method.

[0117] ◆Implementation method) Assume that among 4 cells = {cell #A, cell #B, cell #C, cell #D}, UE#1 has {cell #A, cell #B} configured as SCell, and UE#2 has {cell #B, cell #C, cell #D} configured as SCell. If offset #1 = 0 is configured for UE#1 through UE-specific RRC signaling, the UE can know that the configured SCells are 2 cells starting from the lowest index among a total of N cells. If offset #2 = 1 is configured for UE#2 through UE-specific RRC signaling, the UE can know that the configured SCells are 3 cells starting from the second lowest index among a total of N cells. In this case, if BWP switching for N cells is indicated by GC MAC CE, each UE can determine which cells among the N cells are configured as SCells (for the UE). For example, if '0110' is configured / indicated by the GC MAC CE, UE#1 may apply only the first 2 bits from the left side of '0110', and UE#2 may apply only 3 bits starting from the second bit from the left side.

[0118] -Method 3: Cell indications for K UEs may be serially concatenated to form a GC MAC CE that may be configured for multiple UEs. For example, the GC MAC CE may be configured so that the indication information for each UE may be listed separately in the form of {information for UE#1, information for UE#2, ..., information for UE#N}. In this case, each UE may be assigned / configured with a corresponding bit position from the GC MAC CE (through separate RRC signaling or DCI). Upon receiving the GC MAC CE, the UE may extract and apply the configuration / indication for the cell configured for the UE based on the assigned bit position.

[0119] ■For example, assume that among 4 cells = {cell #A, cell #B, cell #C, cell #D}, UE#1 has {cell #A, cell #B} configured as SCell, and UE#2 has {cell #B, cell #C, cell #D} configured as SCell. The GC MAC CE may be configured in the form of {"BWP switching indication for cell #A of UE#1", "BWP switching indication for cell #B of UE#1", "BWP switching indication for cell #B of UE#2", "BWP switching indication for cell #C of UE#2", "BWP switching indication for cell #D of UE#2"} (to indicate only the cells configured for each UE). Alternatively, the GC MAC CE may be configured in the form of {"cell #A of UE#1", "cell #B of UE#1", ..., "cell #B of UE#2", "cell #C of UE#2", "cell #D of UE#2"} to indicate the total number of cells regardless of the number of cells configured for each UE.

[0120] - Method 4: The mapping information between each bit of the GC MAC CE and the index of the SCell of each UE is configured through separate (UE-specific) RRC signaling. After receiving the GC MAC CE, the UE can determine the BWP switching indication for the SCell configured for the UE based on the mapping information.

[0121] ■For example, assume that among 4 cells = {cell #A, cell #B, cell #C, cell #D}, UE #1 has {cell #A, cell #B} configured as SCell, and UE #2 has {cell #B, cell #C, cell #D} configured as SCell. In this case, cell #A of UE #1 may be mapped to the first bit of the GC MAC CE, cell #B of UE #1 and cell #B of UE #2 may be mapped to the second bit, cell #C of UE #2 may be mapped to the third bit, and cell #D of UE #2 may be mapped to the fourth bit. In this case, if the second bit of the MAC CE is "set", both UE #1 and UE #2 may determine that BWP switching is configured / indicated for cell #B.

[0122] ■In another example, all (or some specific) SCells configured for UE#A may be mapped to specific bits of the GC MAC CE. All (or some specific) SCells configured for UE#B may be mapped to other specific bits of the GC MAC CE. After receiving the GC MAC CE, the UE may determine whether BWP switching for each SCell is configured / indicated (based on the mapping relationship between the SCell configured through RRC signaling and the bits of the MAC CE).

[0123] [2-4] When the method in [2-3] is applied, each bit of the GC MAC CE may indicate a single cell or two or more cells. In this case, each UE may receive information about the cell set indicated by each bit of the GC MAC CE or the number of cells indicated by each bit through UE-specific RRC signaling.

[0124] -For example, each bit of the GC MAC CE may be provided to each UE through RRC signaling to indicate a specific cell set (e.g., intra-band contiguous carriers within a specific frequency band). In this case, K different sets may be jointly activated or deactivated through K bits of the GC MAC CE. In this case, BWP switching may be jointly indicated for K different sets through K bits of the GC MAC CE.

[0125] - In another example, 1 bit of GC MAC CE may be provided to each UE through RRC signaling to indicate G neighboring cells (eg, 2 cells). In this case, BWP switching may be indicated for K*G cells through K bits of GC MAC CE.

[0126] In this case, if the SCell for the UE is configured in a specific group (eg, a unit of a cell set or a unit of G neighboring cells), when the SCell is configured, information indicated by each bit of the GC MAC CE may be configured together.

[0127] [2-5] If the physical cell ID of each cell is directly indicated through the GC MAC CE, the BWP switching configuration for a specific cell can be commonly indicated for multiple UEs.

[0128] [2-6] The above-proposed method can be applied to one of the following cells.

[0129] - Option 1: The proposed method can be applied to all SCells configured (or configurable) for the UE.

[0130] - Option 2: The proposed method can be applied to a subset of all SCells configured (or configurable) for the UE.

[0131] - Option 3: The proposed method may be applied solely to a cell group (eg, MCG or SCG) to which a cell configured (or configurable) for a UE belongs.

[0132] - Option 4: The proposed method may be applied individually based on the FR to which the cell configured (or configurable) for the UE belongs.

[0133] - Option 5: The proposed method may be applied individually based on the type of frequency band to which a cell configured (or configurable) for a UE belongs (eg, a licensed band or an unlicensed band).

[0134] - Option 6: The proposed method may be applied to a PCell or a PSCell configured (or configurable) for a UE.

[0135] ■ For example, in the method in [1-3] above, the bitmap may include PCell and SCell. Alternatively, some SCells may be replaced by PCell (or PSCell) and applied.

[0136] [2-7] The methods in [2-3] to [2-6] can also be applied to BWP switching through GC DCI. For example, each bit of the GC DCI can indicate a specific cell or a set of cells (for multiple UEs) in the same way that each bit of the MAC CE (described above in method 1 or method 2 of [2-3]) indicates a specific cell. As another example, the GC DCI can be configured so that the BWP switching indications for all UEs are listed consecutively (as in method 3 of [2-3]). As another example, the GC DCI can indicate a specific cell or a set of cells (for multiple UEs) based on the mapping relationship between each bit of the DCI and the SCell of each UE (as in method 4 of [2-3]).

[0137] [3] Method to configure / instruct NES BWP via GC MAC CE

[0138] [3-1] For a UE configured with NES mode, if a single NES BWP is configured for each cell (configured for the corresponding UE), the activation or deactivation of the corresponding NES BWP may be configured and / or indicated to each UE via the GC MAC CE (or GC DCI). In other words, the bit index X of the GC MAC CE (or GC DCI) may be used to indicate the on / off (i.e., active / inactive) state of the NES BWP configured for the (specific) cell index Y. In this case, the mapping (or linking) relationship between X and Y may be determined according to the above method. For example, if the bit index X of the GC MAC CE (or GC DCI) is indicated as "1" (or "0"), the active (DL / UL) BWP for cell Y may be switched to the NES BWP. If the bit index X of the GC MAC CE (or GCDCI) is indicated as "0" (or "1"), the active (DL / UL) BWP for cell Y may be switched to the non-NES BWP (or maintained as the current active (DL / UL) BWP). Alternatively, if the bit index X of the GC MAC CE (or GC DCI) is indicated as "0" (or "1"), the active (DL / UL) BWP for cell Y may be switched to a non-NES BWP. If the bit index X of the GC MAC CE (or GC DCI) is indicated as "1" (or "0"), the active (DL / UL) BWP for cell Y may be switched to a NES BWP (or maintained as the current active BWP).

[0139] [3-2] For UEs configured with NES mode, if two NES BWPs are configured for each cell, the activation / deactivation of the corresponding NES BWP can be configured and / or indicated to each UE via GC MAC CE (or GC DCI). In other words, the bit indexes X1 and X2 of the GC MAC CE (or GC DCI) can be used to indicate the on / off (i.e., active / inactive) status of NES BWP#1 and NES BWP#2 configured for (specific) cell index Y. In this case, the mapping (or linking) relationship between X1, X2, NES BWP#1 of Y and NES BWP#2 of Y can be determined according to the above method.

[0140] - Option 1: X1 and X2 may be in the form of a bitmap. For example, two NES BWPs configured for a specific cell may be mapped to X1 and X2, respectively.

[0141] - Option 2: X1 and X2 can be in the form of code points. In other words, 2 bits of X1 and X2 can be used to define 4 states (e.g., "00" = BWP#1, "01" = BWP#2, "10" = BWP#3, and "11" = BWP#4). One of the 4 defined states can be indicated by 2 bits.

[0142] The content of the present disclosure is not limited to being applied only to UL and / or DL ​​signal transmission and reception. For example, the content of the present disclosure can also be used for direct communication between UEs. In this document, the term base station (BS) can be understood as including the concept of relay node and BS. For example, the operation of the BS described in the present disclosure can be performed by a relay node and a BS.

[0143] Obviously, each example in the examples of the proposed method may also be included as an implementation method of the present disclosure, and therefore each example may be considered as one of the proposed methods. Although the above-mentioned proposed methods may be implemented independently, some of the proposed methods may be combined and implemented. In addition, it may be provided that information on whether to apply the proposed method (or information on rules related to the proposed method) is sent from the BS to the UE in a predefined signal (e.g., physical layer signaling or higher layer signaling).

[0144] Implementation Example

[0145] Figure 6 is a flowchart of a resource configuration method according to an embodiment of the present disclosure.

[0146] Reference Figure 6According to an embodiment of the present disclosure, a resource configuration method may include: configuring an SCell (S501); receiving a MAC CE (S503); and performing an operation based on the received MAC CE (S505). Figure 6 In addition to the operations in, you can also perform at least one of the operations described in sections [1] to [3].

[0147] For example, referring to section [1], the MAC CE received in S503 may be a MAC CE for SCell activation / deactivation. As an operation corresponding to S505, the UE performs activation or deactivation of the configured SCell based on the received MAC CE.

[0148] Referring to section [2], the MAC CE received in S503 may be a MAC CE for BWP switching. As an operation corresponding to S505, the UE performs BWP switching for each configured SCell based on the received MAC CE.

[0149] Referring to section [3], the MAC CE received in S503 may be a MAC CE for activating / deactivating NES BWP. As an operation corresponding to S505, the UE activates or deactivates NES BWP for each configured SCell based on the received MAC CE.

[0150] Figure 6 The MAC CEs described in are all GC MAC CEs. Therefore, each MAC CE includes a field (bit) for the first SCell configured for a specific UE and a field (bit) for the second SCell configured for another UE. Specifically, the SCell activation / deactivation MAC CE includes a C field for indicating activation and deactivation of the first SCell and a C field for indicating activation and deactivation of the second SCell. The MAC CE for BWP switching includes a field for indicating BWP switching for the first SCell and the second SCell. The MAC CE for activating / deactivating NES BWP includes a field for indicating activation and deactivation of NES BWP for the first SCell and the second SCell.

[0151] Regarding the method of indicating a specific operation in a GC manner, the method in Section [1-2], Section [2-2] and / or Section [3-2] can be used.

[0152] For example, according to method 1 in section [1-2], the index of the first SCell and the index of the second SCell may be GC indexes applied to both the UE and the other UE. Alternatively, according to method 2 or method 4, mapping information between the index of the first SCell and the C field may be configured for a specific UE. Alternatively, according to method 3, the position of the C field for a specific UE in the C field in the MAC CE may be configured for a specific UE.

[0153] The SCell indicating a specific operation through the GC MAC CE can be a cell within the scope of sections [1-6] and / or sections [2-6]. Therefore, the first SCell can be all or some of the SCells configured (or configurable) for the UE. Alternatively, the first SCell can be a cell belonging to a specific cell group (e.g., MCG or SCG), a cell within a specific FR (e.g., FR1, FR2, or FR2-2), or a cell within a specific frequency band type (e.g., operation with or without shared spectrum) among the SCells configured or configurable for the UE. In addition, the GC MAC CE can be used not only for SCells, but also for cells including PCells and PSCells.

[0154] Although not illustrated, the BS operation corresponding to the UE operation may include: configuring the first SCell for the first UE and configuring the second SCell for the second UE through RRC signaling; and sending MAC CE to the first UE and the second UE. The specific configuration of MAC CE may be the same as previously described with respect to the UE.

[0155] In addition to reference Figure 6 In addition to the operations described, you can also combine and further perform reference Figures 1 to 5 And / or one or more of the operations described in sections [1] to [3].

[0158] More specific examples will be described below with reference to the accompanying drawings.In the following drawings / descriptions, unless otherwise specified, the same reference numerals represent the same or corresponding hardware blocks, software blocks or functional blocks.

[0159] Figure 7 A communication system 1 applied to the present disclosure is illustrated.

[0160] refer to Figure 7, the communication system 1 applied to the present disclosure includes a wireless device, a BS, and a network. The wireless device is a device that performs communication using a radio access technology (RAT) (e.g., 5G NR (or new RAT) or LTE), also referred to as a communication / radio / 5G device. The wireless device may include (but is not limited to) a robot 100a, a vehicle 100b-1 and 100b-2, an extended reality (XR) device 100c, a handheld device 100d, a home appliance 100e, an IoT device 100f, and an artificial intelligence (AI) device / server 400. For example, a vehicle may include a vehicle with a wireless communication function, an autonomous driving vehicle, and a vehicle capable of vehicle-to-vehicle (V2V) communication. In this article, a vehicle may include an unmanned aerial vehicle (UAV) (e.g., a drone). The XR device may include an augmented reality (AR) / virtual reality (VR) / mixed reality (MR) device, and may be implemented in the form of a head-mounted device (HMD), a head-up display (HUD) installed in a vehicle, a television (TV), a smart phone, a computer, a wearable device, a home appliance, a digital signage, a vehicle, a robot, etc. Handheld devices may include smart phones, smart boards, wearable devices (e.g., smart watches or smart glasses), and computers (e.g., laptop computers). Home appliances may include TVs, refrigerators, washing machines, etc. IoT devices may include sensors, smart meters, etc. For example, a BS and a network may be implemented as wireless devices, and a specific wireless device 200a may operate as a BS / network node for other wireless devices.

[0161] The wireless devices 100a to 100f may be connected to the network 300 via the BS 200. The AI ​​technology may be applied to the wireless devices 100a to 100f, and the wireless devices 100a to 100f may be connected to the AI ​​server 400 via the network 300. The network 300 may be configured using a 3G network, a 4G (e.g., LTE) network, or a 5G (e.g., NR) network. Although the wireless devices 100a to 100f may communicate with each other via the BS 200 / network 300, the wireless devices 100a to 100f may perform direct communication (e.g., side link communication) with each other without the intervention of the BS / network. For example, the vehicles 100b-1 and 100b-2 may perform direct communication (e.g., V2V / vehicle-to-everything (V2X) communication). An IoT device (e.g., a sensor) may perform direct communication with other IoT devices (e.g., a sensor) or other wireless devices 100a to 100f.

[0162] Wireless communication / connection 150a, 150b and 150c can be established between wireless devices 100a to 100f / BS200 and between BS200. Herein, wireless communication / connection can be established through various RATs (e.g., 5G NR) such as UL / DL communication 150a, side link communication 150b (or D2D communication) or inter-BS communication (e.g., relay or integrated access backhaul (IAB)). Wireless signals can be sent and received between wireless devices, between wireless devices and BSs, and between BSs through wireless communication / connection 150a, 150b and 150c. For example, signals can be sent and received via various physical channels through wireless communication / connection 150a, 150b and 150c. To this end, at least a portion of various configuration information for configuring processes for sending / receiving wireless signals, various signal processing processes (e.g., channel coding / decoding, modulation / demodulation and resource mapping / demapping) and resource allocation processes can be performed based on various proposals of the present disclosure.
