Common Search Space is the specific search space that every UE need to search for the signals for every UE (e.g, PDCCH for SIB) or signaling message that is applied to every UE before dedicated channel is established for a specific UE(e.g, PDCCH used during RACH process).
Read moreWhat is CCE aggregation level?
The CCE aggregation level is given by the PDCCH format and determines the number of PDCCH candidates in a search space . The number of candidates and size of the search space for each aggregation level is given in the following table.
Read moreWhat is BWP in 5G?
One of the basic concepts in 5G NR is bandwidth part (BWP), which is, at a high level, a set of contiguous resource blocks configured inside a channel bandwidth .
Read moreHow many bandwidth parts can be active anytime for each UE?
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 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
