There are Nsymbslotconsecutive OFDM symbols in a slot where Nsymbslotdepends on the cyclic prefix as given by Tables 4.3.2-1 and 4.3.2-2. The start of slot nsμin a subframe is aligned in time with the start of OFDM symbol nsμNsymbslotin the same subframe.OFDM symbols in a slot in a downlink or uplink frame can be classified as 'downlink', 'flexible', or 'uplink'. Signaling of slot formats is described in clause 11.1 of [5, TS 38.213]. In a slot in a downlink frame, the UE shall assume that downlink transmissions only occur in 'downlink' or 'flexible' symbols.In a slot in an uplink frame, the UE shall only transmit in 'uplink' or 'flexible' symbols.A UE not capable of full-duplex communication and not supporting simultaneous transmission and reception as defined by parameter simultaneousRxTxInterBandENDC, simultaneousRxTxInterBandCA or simultaneousRxTxSUL[10, TS 38.306] among all cells within a group of cells is not expected to transmit in the uplink in one cell within the group of cells earlier than NRx-TxTcafter the end of the last received downlink symbol in the same or different cell within the group of cells where NRx-Txis given by Table 4.3.2-3.

Two antenna ports are said to be quasi co-located if the large-scale properties of the channel over which a symbol on one antenna port is conveyed can be inferred from the channel over which a symbol on the other antenna port is conveyed. The large-scale properties include one or more of delay spread, Doppler spread, Doppler shift, average gain, average delay, and spatial Rx parameters. 4.4.2Resource gridFor each numerology and carrier, a resource grid of Ngrid,xsize,μNscRBsubcarriers and Nsymbsubframe, μOFDM symbols is defined, starting at common resource block Ngridstart, μindicated by higher-layer signalling. There is one set of resource grids per transmission direction (uplink, downlink, or sidelink) with the subscriptxset to DL, UL, and SL for downlink, uplink, and sidelink, respectively. When there is no risk for confusion, the subscript xmay be dropped. There is one resource grid for a given antenna port p, subcarrier spacing configuration μ, and transmission direction (downlink, uplink, or sidelink). For uplink and downlink, the carrier bandwidth Ngridsize, μfor subcarrier spacing configuration μis given by the higher-layer parameter carrierBandwidthin the SCS-SpecificCarrierIE. The starting position Ngridstart, μfor subcarrier spacing configuration μis given by the higher-layer parameter offsetToCarrierin the SCS-SpecificCarrierIE.The frequency location of a subcarrier refers to the center frequency of that subcarrier.3GPP TS 38.211 V18.4.0 (2024-09)14(Release 18)

3GPPFor the downlink, the higher-layer parameter txDirectCurrentLocationin the SCS-SpecificCarrierIE indicates the location of the transmitter DC subcarrier in the downlink for each of the numerologies configured in the downlink. Values in the range 0 – 3299 represent the number of the DC subcarrier and the value 3300 indicates that the DC subcarrier is located outside the resource grid.For the uplink, the higher-layer parameter txDirectCurrentLocationin the UplinkTxDirectCurrentBWPIE indicates the location of the transmitter DC subcarrier in the uplink for each of the configured bandwidth parts, including whether the DC subcarrier location is offset by 7.5 kHz relative to the center of the indicated subcarrier or not. Values in the range 0 – 3299 represent the number of the DC subcarrier, the value 3300 indicates that the DC subcarrier is located outside the resource grid, and the value 3301 indicates that the position of the DC subcarrier in the uplink is undetermined.4.4.3Resource elementsEach element in the resource grid for antenna port pand subcarrier spacing configuration μis called a resource element and is uniquely identified by (k ,l)p, μwhere kis the index in the frequency domain and lrefers to the symbol position in the time domain relative to some reference point. Resource element (k ,l)p, μcorresponds to a physical resource and the complex value ak ,l(p, μ). When there is no risk for confusion, or no particular antenna port or subcarrier spacing is specified, the indices pand μmay be dropped, resulting in ak ,l(p)or ak ,l.4.4.4Resource blocks4.4.4.1GeneralA resource block is defined as NscRB=12consecutive subcarriers in the frequency domain. 4.4.4.2Point APoint A serves as a common reference point for resource block grids and is obtained from:-offsetToPointAfor a PCell downlink where offsetToPointArepresents the frequency offset between point A and the lowest subcarrier of the lowest resource block, which overlaps with the SS/PBCH block, or the SS/PBCH block after puncturing if applicable, used by the UE for initial cell selection, expressed in units of resource blocks assuming 15 kHz subcarrier spacing for FR1 and 60 kHz subcarrier spacing for FR2 and FR2-NTN;-for operation without shared spectrum channel access in FR1, FR2-1 and FR2-NTN, the lowest resource block has the subcarrier spacing provided by the higher layer parameter subCarrierSpacingCommon;-for operation with shared spectrum channel access in FR1 or FR2, and for operation without shared spectrum channel access in FR2-2, the lowest resource block has the subcarrier spacing same as the SS/PBCH block used by the UE for initial cell selection;-absoluteFrequencyPointAfor all other cases where absoluteFrequencyPointArepresents the frequency-location of point A expressed as in ARFCN.4.4.4.3Common resource blocksCommon resource blocks are numbered from 0 and upwards in the frequency domain for subcarrier spacing configuration μ. The center of subcarrier 0 of common resource block 0 for subcarrier spacing configuration μcoincides with 'point A'. The relation between the common resource block number nCRBμin the frequency domain and resource elements (k ,l)for subcarrier spacing configuration μis given bynCRBμ=⌊kNscRB⌋where kis defined relative to point A such that k=0corresponds to the subcarrier centered around point A.3GPP TS 38.211 V18.4.0 (2024-09)15(Release 18)

Configuration of a bandwidth part is described in clause 12 of [5, TS 38.213].A UE can be configured with up to four bandwidth parts in the downlink with a single downlink bandwidth part being active at a given time. The UE is not expected to receive PDSCH, PDCCH, or CSI-RS (except for RRM) outside an active bandwidth part.A UE can be configured with up to four bandwidth parts in the uplink with a single uplink bandwidth part being active at a given time. If a UE is configured with a supplementary uplink, the UE can in addition be configured with up to four bandwidth parts in the supplementary uplink with a single supplementary uplink bandwidth part being active at a given time. The UE shall not transmit PUSCH or PUCCH outside an active bandwidth part. For an active cell, the UE shall not transmit SRS configured by SRS-Resourceoutside an active bandwidth part.Unless otherwise noted, the description in this specification applies to each of the bandwidth parts.

Base sequences ru,v(n)are divided into groups, where u∈{0,1,…,29}is the group number and vis the base sequence number within the group, such that each group contains one base sequence (v=0) of length M=m NscRB/2δ, 1/2≤m/2δ.
