Claim 18:
19. The non-transitory computer readable memory medium of claim 17,
wherein, to determine the default beam for transmissions based, at least in part, on a PRACH procedure, the program instructions are further executable to cause the UE to determine the default beam for transmissions based, at least in part, on a beam used for a most recent PRACH procedure in the CC, in a CC in a same band as the CC, in a same band group as the CC, in a same cell group as the CC, or in a same CC list group as the CC;
wherein, to determine the default beam for transmissions based, at least in part, on a PUSCH transmission, the program instructions are further executable to cause the UE to determine the default beam for transmissions based, at least in part, on a beam used for a most recent PUSCH transmission in the CC, in a CC in a same band as the CC, in a same band group as the CC, in a same cell group as the CC, or in a same CC list group as the CC;
wherein, to determine the default beam for transmissions based, at least in part, on an SRS transmission, the program instructions are further executable to cause the UE to determine the default beam for transmissions based, at least in part, on a beam used for a most recent SRS transmission in the CC, in a CC in a same band as the CC, in a same band group as the CC, in a same cell group as the CC, or in a same CC list group as the CC; and
wherein, to determine the default beam for transmissions based, at least in part, on a PUCCH transmission, the program instructions are further executable to cause the UE to determine the default beam for transmissions based, at least in part, on a beam used for a most recent PUCCH transmission in the CC, in a CC in a same band as the CC, in a same band group as the CC, in a same cell group as the CC, or in a same CC list group as the CC.
