A UE can be configured with up to four bandwidth parts in the downlink, with a single downlink bandwidth part being active at one time.
Read moreWhat is a carrier bandwidth?
According to 38.211 4.4. 5, A carrier bandwidth part is defined as follows : Carrier Bandwidth Part is a contiguous set of physical resource blocks,selected from a contiguous subset of the common resource blocks for a given numerology(u) on a given carrier .
Read moreWhat is CRB 5G?
CRB refer to common resource block , i.e. BW of 5G divided into multiple CRB used for BWP. PRB refer to block assigned to user by scheduler. In 5G we have VRB to PRB mapping which depends on Downlink resource allocation type, it can be interleaved or non inter leaved.
Read moreWhat is OFDM numerology?
OFDM numerology design for wide range of carrier frequencies, deployment types, and application latency requirements using regular slots . 100 GHz. Frequency. 15 kHz. 30 kHz.
Read moreWhat is a bandwidth part?
A Bandwidth Part (BWP) is a contiguous set of physical resource blocks (PRBs) on a given carrier . These RBs are selected from a contiguous subset of the common resource blocks for a given numerology (u). It is denoted by BWP. Each BWP defined for a numerology can have following three different parameters.28 Eyl 2018
Read moreWhat is initial bandwidth part?
Initial BWP is used to performs Initial Access Process . It includes Parameters like RMSI (Requested Minimum System Information), CORESET* and RMSI Frequency location/bandwidth/SCS. It can be 24~96 PRBs with different settings and relaxed to wider BWP after RMSI decoding.
Read moreHow do you find the number of subcarriers in 5G?
Number of subcarrier per PRB is 12 . Number of OFDM symbols per slot may vary depending on subcarrier spacing. For subcarrier spacing <= 60, the number of OFDM symbols / slot = 7 or 14. For subcarrier spacing > 60, the number of OFDM symbols / slot = 14.
