wherein in case that the signal related to the first preamble is for the four-step random access type, the backoff indicator included in the Msg 2 is applied for the signal related to the second preamble. pg 16 para 6 Step 504a: In the case that the two-step random access procedure fails, the terminal performs random access resource selection among the target type random access resources within the backoff time when the first condition is satisfied within the backoff time. The target type random access resource is a four-step random access resource. pg 16 para 9 - If step 504a is performed, the terminal can initiate random access with the random access resource selected within the backoff time.
It would have been obvious to a person having an ordinary skill in the art before the effective filing date of the claimed invention to modify the system of Rune in view of Li wherein in case that the signal related to the first preamble is for the two-step random access type, the backoff indicator included in the Msg B is applied for the signal related to the second preamble, and wherein in case that the signal related to the first preamble is for the four-step random access type, the backoff indicator included in the Msg 2 is applied for the signal related to the second preamble as taught by NPL1 to add threshold value to make a decision between two or 4 step RACH to saving power.
Regarding Claim 15, Rune teaches, The base station of claim 14, wherein the Msg 2 includes response information on random access and [32]- The network, i.e., the gNB, also transmits a Msg2 to the requesting WD, in response to the Msg1, confirming the successful reception of the Msg1 and confirming that the requested SI will be broadcast.
wherein the Msg B includes response information on random access and contention resolution-related information. [108]-[114]
Network response to msgA (i.e., msgB/msg2) can include the following:
Regarding Claim 16, Rune teaches, The base station of The base station of wherein in case that the signal related to the first preamble is for the two-step random access type, the signal related to the second preamble is received after a backoff time corresponding to the backoff indicator included in the Msg B, and Section 2.2-Q7-OPPO- We prefer to have two parts msgB (=msg B indicates two step). MsgB includes BI and backoff indication (=backoff indicator in MSG B) which is addressed to multiple UEs.
wherein in case that the signal related to the first preamble is for the Four-step random access type, the signal related to the second preamble is received after a backoff time corresponding to the backoff indicator included in the Msg 2. [794]- 4> perform the Random Access Resource selection procedure (see subclause 5.1.2) after the backoff time.5> 5> continue the procedure with 4-step RA only.
Conclusion
THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action.
