5.3 25.102 - UE Radio transmission and reception (TDD)

R4-021559 Introduction of Rel-5 clarifications and small corrections in Rel-4 (CR 129 to 25.102 Rel-4) (Siemens)

Decision: The CR is agreed

R4-021576 Name correction of logical and transport channels (CR 130 to 25.102 Rel-4) (Siemens)

R4-021577 Name correction of logical and transport channels (CR 131 to 25.102 Rel-5) (Siemens)

Decision: The CRs are agreed

5.3.1 TDD HSDPA

5.3.1.1 Fixed Reference Channel

R4-021539 HSDPA simulation assumptions for 3,84 Mcps TDD option with fixed reference channels (InterDigital)

Frederic Charpentier (Siemens) pointed out that the IR combining is not considered in the simulation. If it is not included, this UE technique will not be tested. The chairman suggest to provide different simulations comparing Chase and IR combining to see if there is any difference in terms of performance. Joseph Levy (Interdigital) noted that preliminary analysis so far didn't show a substantial difference.

Decision: The assumptions are agreed
R4-021540 HSDPA simulation results for 3,84 Mcps TDD, Fixed Reference Channel (InterDigital)

R4-021541 Addition of HSDPA UE requirements for 3,84 Mcps TDD option for 16QAM and QPSK for fixed reference channels (CR 127 to 25.102 Rel-5) (InterDigital)

Frederic Charpentier (Siemens) presented some objections to the simulation results in R4-021540. Decision: The CR is revised

R4-021665 HSDPA simulation results for 3,84 Mcps TDD, Fixed Reference Channel (InterDigital)

R4-021666 Addition of HSDPA UE requirements for 3,84 Mcps TDD option for 16QAM and QPSK for fixed reference channels (CR 127r1 to 25.102 Rel-5) (InterDigital)

These simulation results and attached CR cover the concerns raised by Siemens

Decision: The CR is agreed
R4-021402 Simulation results for QPSK and 16QAM for 1,28 Mcps TDD option (Motorola)

These results are not included in R4-021601/R4-021602, which summarize the results from different companies (Samsung, Siemens, Panasonic). The results from Motorola are however in line with previous papers. Samsung will produce a revision of the comparison paper (R4-021601) and the CR (R4-021602) taking into account the results from Motorola.

R4-021600 HSDPA simulation results for 1.28 Mcps TDD option (Samsung)

R4-021604 Updated HSDPA simulation results for 1.28Mcps TDD option (Panasonic)

Decision :The simulations are noted

R4-021637 Comparison of HSDPA simulation results for 1.28 Mcps TDD option (Samsung, Siemens, Panasonic, Motorola)

R4-021638 HSDPA UE requirements for 1.28 Mcps TDD option for 16QAM and QPSK for fixed reference channels (CR 132r1 to 25.102 Rel-5) (Samsung, Siemens, Panasonic, Motorola)

These documents are the revisions of R4-021601 and R4-021602.

Decision: The CR is agreed.
