Methods for determining paging occasions in eDRX cycle and monitoring paging occasions based on CEL
Embodiments herein provide a method for determining PO by UEs in an eDRX cycle. The method includes determining PHs in the eDRX cycle based on estimated values of UE_ID_H and number of hyper-frames in the eDRX cycle. The method includes determining a first radio frame of PTW based on a determined value of N PTW and i eDRX . The method includes determining a last radio frame of PTW based on the first radio frame and length of the PTW. The method includes determining PFs in the PTW. The determination of PFs is based on the UE_ID. The method includes determining the POs, in each of the determined PFs, based on an index associated with each of the POs. The index associated with each PO is computed based on the UE_ID, number of frames available for paging in a DRX cycle, and number of sub-frames available for paging in each PF.
1. A method of a user equipment (UE) for determining paging occasion (PO) in extended discontinuous reception (eDRX), the method comprising:
determining a paging hyper-frame (PH) based on a first UE identity;
determining paging window (PW) based on the first UE identity;
determining a paging frame (PF) based on a second UE identity; and
determining the PO in the PF based on the second UE identity, wherein:
the first UE identity and the second UE identity are different;
a first radio frame of the PW is determined based on the first UE identity and an eDRX cycle of the UE in hyper-frames; and
a last radio frame of the PW is determined based on the first radio frame of the PW and a length of the PW.
2. The method of claim 1 , wherein the PH is determined based on the first UE identity and the eDRX cycle of the UE in the hyper-frames.
3. The method of claim 1 , wherein the PO is determined based on an index associated with the PO, and the index associated with the PO is determined based on the second UE identity.
4. The method of claim 1 , wherein the first UE identity is determined based on a system architecture evolution-temporary mobile subscriber identity (S-TMSI).
5. The method of claim 1 , wherein the second UE identity is determined based on an international mobile subscriber identity (IMSI).
6. The method of claim 1 , further comprising:
monitoring the PO for receiving a paging message for the UE.
7. A user equipment (UE) for determining paging occasion (PO) in extended discontinuous reception (eDRX), the UE comprising:
transceiver configured to transmit and receive a signal; and
controller configured to determine a paging hyper-frame (PH) based on a first UE identity, to determine paging window (PW) based on the first UE identity, to determine a paging frame (PF) based on a second UE identity, and to determine the PO in the PF based on the second UE identity,
wherein the first UE identity and the second UE identity are different, and
wherein the controller is configured to determine a first radio frame of the PW based on the first UE identity and an eDRX cycle of the UE in hyper-frames, and to determine a last radio frame of the PW based on the first radio frame of the PW and length of the PW.
8. The UE of claim 7 , wherein the PH is determined based on the first UE identity and the eDRX cycle of the UE in the hyper-frames.
9. The UE of claim 7 , wherein the PO is determined based on an index associated with the PO, and the index associated with the PO is determined based on the second UE identity.
10. The UE of claim 7 , wherein the first UE identity is determined based on a system architecture evolution-temporary mobile subscriber identity (S-TMSI).
11. The UE of claim 7 , wherein the second UE identity is determined based on an international mobile subscriber identity (IMSI).
12. The UE of claim 7 , wherein the controller is configured to monitor the PO for receiving a paging message for the UE.
