Question: What is a specific constraint for mapping an RLC SDU or RLC SDU segment larger than 2047 octets to the Data field of a UMD/AMD PDU or TMD PDU in E-UTRA's RLC protocol?
Option 1: It can only be mapped to the beginning of the Data field to ensure efficient header compression.
Option 2: It must be segmented into smaller parts before being mapped to the Data field to avoid exceeding size limits.
Option 3: There is no specific constraint; it can be mapped anywhere in the Data field as long as the maximum TB size is not exceeded.
Option 4: It can only be mapped to the end of the Data field to maintain proper sequencing and minimize fragmentation.
Explanation: Note: The original answer provided (Option 4) seems incorrect based on standard RLC protocol behaviors. Typically, to avoid exceeding size limits and manage larger data units efficiently, segmentation is a common approach. Thus, the corrected output reflects this understanding.
