6 Simultaneous transmission and reception of physical channels and physical signals p. 12
This clause describes the requirements from the UE to send and receive multiple physical channels and physical signals simultaneously depending on the capabilities and service requirements. The following notation is used between both the uplink and downlink clauses below.
- p is the number of uplink carriers configured for the UE on which physical channels can be transmitted
- p' is the number of uplink carriers configured for the UE on which SRS can be transmitted
- q is the number of downlink carriers configured for the UE
- j is the number of cell groups configured for the UE.
- k is the number of PUCCH groups configured for the UE.
6.1 Uplink p. 12
Table 6.1-1 and Table 6.1-2 describe the possible combinations of physical channels and SRS that can be sent in simultaneously in the uplink by one UE. Table 6.1-1 introduces notation for a "Transmission Type" which represents a physical channel or sounding reference signal, and any associated transport channel. Table 6.1-2 describes the combinations of these "Transmission Types" which are supported by the UE depending on capabilities (TS 38.306), and enumerates how many of each can be transmitted simultaneously.

| A | PRACH | RACH | Note 1, Note 3 |
| B | PUCCH | N/A | |
| C | PUSCH | UL-SCH | Note 2, Note 3 |
