Transient period of Rx->Tx at eNB side exists and also contained in GP.
Although I can not fully understand yet, I can show you the paragraph from book, [Section 23.4.1, Page 567] reads:
Overall, the total guard time TG at a TDD eNodeB per uplink-downlink cycle is equal
to the sum of TG1 and TG2, as given by Equation (23.11). In the LTE specifications this
is represented by a single guard period amalgamating both parts (with the uplink subframe
timing advanced by an amount TG2 at the eNodeB with respect to the downlink timing). This
is only a matter of representation, however, and the end result is essentially identical to the
presence of the two separate guard periods:
