BIT STRING (6..4400, …) |
Each position in the bitmap represents a PRB pair in a subframe; value "0" indicates "PCell resource not intended to be used for transmission by the sending node", value "1" indicates "PCell resource intended to be used for transmission by the sending node". The bit string spans from the first PRB pair of the first represented subframe to the last PRB pair of the same subframe and then moves to the following PRBs in the following subframes in the same order. Each position is applicable only in positions corresponding to UL subframes. The bit string may span across multiple contiguous subframes (maximum 40). The first position of the UL Coordination Information corresponds to the receiving node’s subframe 0 in a receiving node’s radio frame where SFN = 0. The length of the bit string is an integer multiple of . The UL Coordination Information is continuously repeated. |
