only SUL bands are counted, but SDL bands are not counted; or
all of SDL and SUL bands are counted.
13 . The wireless device of claim 12 , wherein the second number of carrier types is counted by not taking the SDL bands and the SUL bands into consideration or taking the SDL bands and the SUL bands into consideration according to one of the following:
only SDL bands are counted, but SUL bands are not counted;
only SUL bands are counted, but SDL bands are not counted; or
all of SDL and SUL bands are counted.
14 . The wireless device of claim 11 , wherein the PUCCH grouping capability information or the PUCCH location capability information indicates the carrier types of bands for a primary PUCCH group and a secondary PUCCH group, respectively, and
wherein the carrier types of bands are indicated by using a bitmap including a number of bits included in the PUCCH capability report, the number of bits in the bitmap being determined in accordance with the second number of carrier types contained in the band combination (BC).
15 . The wireless device of claim 14 , wherein the carrier types of bands are indicated by using an index into a list of bitmaps independently for the primary PUCCH group and the secondary PUCCH group for each BC.
