Section: 5.4A Short Physical Uplink Control Channel 5.4A.1 General
Content: The short physical uplink control channel, SPUCCH, carries uplink control information. Simultaneous transmission of SPUCCH and PUSCH from the same UE where both SPUCCH and PUSCH is using either slot or subslot transmission is supported if enabled by higher layers (see simultaneousPUCCH-PUSCH in TS 36.331[ Evolved Universal Terrestrial Radio Access (E-UTRA); Radio Resource Control (RRC); Protocol specification ]  [9]). For frame structure type 2 and in UpPTS, transmission of SPUCCH is not supported. SPUCCH supports multiple formats as shown in Table 5.4A-1 and Table 5.4A-2 with different number of bits carried by each SPUCCH. Table 5.4A-1: SPUCCH formats for slot transmission Table 5.4A-2: SPUCCH formats for subslot transmission The quantity represents the bandwidth of the SPUCCH format 4 as defined by clause 5.4A.4.1, and and are defined in Table 5.4A.4.1-1 and Table 5.4A.4.2-1, respectively. SPUCCH formats 1/1a/1b use a cyclic shift, , which varies with the symbol number and the slot number as described in clause 5.4.
