5.3 BS channel bandwidth p. 37

5.3.1 General p. 37

The BS channel bandwidth supports a single NR RF carrier in the uplink or downlink at the Base Station. Different UE channel bandwidths may be supported within the same spectrum for transmitting to and receiving from UEs connected to the BS. The placement of the UE channel bandwidth is flexible but can only be completely within the BS channel bandwidth. The BS shall be able to transmit to and/or receive from one or more UE bandwidth parts that are smaller than or equal to the number of carrier resource blocks on the RF carrier, in any part of the carrier resource blocks.

The relationship between the channel bandwidth, the guardband and the transmission bandwidth configuration is shown in Figure 5.3.1-1.

In the case that multiple numerologies are multiplexed in the same symbol, the minimum guardband on each side of the carrier is the guardband applied at the configured BS channel bandwidth for the numerology that is transmitted/received immediately adjacent to the guard band.

For FR1, if multiple numerologies are multiplexed in the same symbol and the BS channel bandwidth is >50 MHz, the guardband applied adjacent to 15 kHz SCS shall be the same as the guardband defined for 30 kHz SCS for the same BS channel bandwidth.

For FR2, if multiple numerologies are multiplexed in the same symbol and the BS channel bandwidth is >200 MHz, the guardband applied adjacent to 60 kHz SCS shall be the same as the guardband defined for 120 kHz SCS for the same BS channel bandwidth.

5.3.4 RB alignment p. 40

For each BS channel bandwidth and each numerology, BS transmission bandwidth configuration must fulfil the minimum guardband requirement specified in clause 5.3.3.

For each numerology, its common resource blocks are specified in clause 4.4.4.3 of TS 38.211, and the starting point of its transmission bandwidth configuration on the common resource block grid for a given channel bandwidth is indicated by an offset to "Reference point A" in the unit of the numerology.

For each numerology, all UE transmission bandwidth configurations indicated to UEs served by the BS by higher layer parameter carrierBandwidth defined in TS 38.331 shall fall within the BS transmission bandwidth configuration.

The requirements in this specification apply to the combination of BS channel bandwidths, SCS and operating bands shown in Table 5.3.5-1 for FR1 and in Table 5.3.5-2 and Table 5.3.5-3 for FR2. The transmission bandwidth configuration in Table 5.3.2-1, Table 5.3.2-2 and Table 5.3.2-3 shall be supported for each of the BS channel bandwidths within the BS capability. The BS channel bandwidths are specified for both the Tx and Rx path.

NOTE 1: For this bandwidth, the minimum requirements are restricted to operation when carrier is configured as an downlink SCell part of CA configuration. NOTE 2: For this bandwidth, the minimum requirements are restricted to operation when carrier is configured as an SCell part of DC or CA configuration. NOTE 3: For this bandwidth, it only applies for UL transmission. NOTE 4: For this bandwidth, the minimum requirements are restricted to operation when carrier is configured as an SCell part of DC or CA configuration. NOTE 5: Void. NOTE 6: This bandwidth can only be applied in certain regions where the absence of non 3GPP technologies can be guaranteed on a long term basis in this version of specification. NOTE 7: For this bandwidth, it only applies for DL transmission. NOTE 8: Not all frequency positions of 5 MHz carriers are possible due limitations of the SSB position relative to the 5 MHz channels. 5 MHz channels with F_c such that 2499+N1.2 ≤F_c<2499.3+N1.2MHz for 0≤N<157 are not compatible with SSB positions and cannot be used for 5 MHz n41.
