context: for each time slot. The TPC symbols shall then be transmitted using the physical channels with the NTPC+1 lowest physical channel sequence numbers (p) in that time slot. Physical channel sequence numbering is determined by the rate matching function and is described in [7]. If the rate matching function results in NRM < NTPC+1 remaining physical channels in this time slot, TPC symbols shall be transmitted only on the NRM remaining physical channels. The TPC symbols are spread with the same spreading factor (SF) and spreading code as the data parts of the respective physical channel. Figure 18G: Position of TPC information in the traffic burst in downlink and uplink For the number of TPC symbols per time slot there are 3 possibilities, that can be configured by higher layers, individually for each timeslot: 1) one TPC symbol 2) no TPC symbols 3) 16/SF TPC symbols So, in case 3), when SF=1, there are 16 TPC symbols which correspond to 32 bits (for QPSK) and 48 bits (for 8PSK).

description: Remote Electrical Tilting (RET) refers to a mechanism used in the coaxial interface option for controlling the tilt of an antenna remotely through electrical signals. It involves the transmission of RET commands from the Base Station (BS) to the RET antenna, which then adjusts its position accordingly.
explanation: The context provided describes the process of remote electrical tilting in detail, highlighting its role in the coaxial interface option and how it is used for controlling antenna tilt. Given this specific usage and explanation within the context of a 3GPP specification (TS 25.802), RET does not fit neatly into any predefined category other than Miscellaneous, as it pertains to a specialized function within telecommunications infrastructure.
