Definitions

  • the resource grid is divided into multiple resource elements (REs).
  • REs resource elements
  • an RB may contain 12 consecutive subcarriers in the frequency domain and 7 consecutive symbols (for DL, OFDM symbols; for UL, SC-FDMA symbols) in the time domain, for a total of 84 REs.
  • an RB may contain 12 consecutive subcarriers in the frequency domain and 6 consecutive symbols in the time domain, for a total of 72 REs.
  • the number of bits carried by each RE depends on the modulation scheme.
  • some of the REs carry DL reference (pilot) signals (DL- RS) for channel estimation at the UE.
  • DL- RS DL reference (pilot) signals
  • the UE may decode the PBCHs and check CRC. The UE may determine the PBCHs and check CRC. The UE may determine the PBCHs and check CRC.
  • the UE 704 may detect the SS blocks from the second base station 706 prior to receiving the information from the first base station 702.
  • the UE may detect the cell ID of the second base station 706.
  • the UE may report the cell ID to the first base station 702 at 716.
  • the first base station 702 may provide the PBCH bit information for the second base station 706 to the UE at 718.
  • the UE may then use the information from the first cell 702 to decode the second base station's PBCH using the successive decoding order at 720.
  • Combinations such as "at least one of A, B, or C,” “one or more of A, B, or C,” “at least one of A, B, and C,” “one or more of A, B, and C,” and "A, B, C, or any combination thereof include any combination of A, B, and/or C, and may include multiples of A, multiples of B, or multiples of C.
