[0027] I. Introduction
[0028] The present patent document describes paging occasion configurations that reduce network energy consumption.
[0029] In 5G advanced and 6G communication, green communication system will be a promising direction for communication development. This aims to deal with the case causing large power consumption for both base station (BS) side and user equipment (UE) side. From the perspective of base station, paging occasion configurations for both idle / inactive UE and connected UE are more likely to be an even paging occasions configuration within one paging period, which makes base station hard to go-to-sleep in some cases, including, e.g., light system load.
[0030] To this end, this patent document aims to provide a method for network energy saving based paging configurations and a method for achieving paging configuration adaptation in order to achieve network energy saving.
[0031] Current paging occasion configuration is described in TS 38.304, excerpted below including paging frame &starting paging occasion for UEs.
[0032] 7. Paging
[0033] 7.1 Discontinuous Reception for paging
[0034] The PF and PO for paging are determined by the following formulae:
[0035] SFN for the PF is determined by:
[0036] (SFN + PF_offset) mod T = (T div N) * (UE_ID mod N) (1)
[0037] Index (i_s) , indicating the index of the PO is determined by:
[0038] i_s= floor (UE_ID / N) mod Ns (2)
[0039] The PDCCH monitoring occasions for paging are determined according to pagingSearchSpace as specified in TS 38.213 and firstPDCCH-MonitoringOccasionOfPO and nrofPDCCH-MonitoringOccasionPerSSB-InPO if configured as specified in TS 38.331. When SearchSpaceId = 0 is configured for pagingSearchSpace, the PDCCH monitoring occasions for paging are same as for RMSI as defined in clause 13 in TS 38.213.
[0040] With the two formulae, the paging frame for one UE and the starting paging occasion can be determined. And the paging occasion determination is based on the configuration of physical downlink control channel (PDCCH) monitoring occasion. The paging occasion determination is described in TS 38.304, excerpted below.
[0041] A PO is a set of 'S*X ' consecutive PDCCH monitoring occasions where 'S ' is the number of actual transmitted SSBs determined according to ssb-PositionsInBurst in SIB1 and X is the nrofPDCCH-MonitoringOccasionPerSSB-InPO if configured or is equal to 1 otherwise. The [x*S+K] th PDCCH monitoring occasion for paging in the PO corresponds to the Kth transmitted SSB, where x=0, 1, …, X-1, K=1, 2, …, S. The PDCCH monitoring occasions for paging which do not overlap with UL symbols (determined according to tdd-UL-DL-ConfigurationCommon) are sequentially numbered from zero starting from the first PDCCH monitoring occasion for paging in the PF. When firstPDCCH-MonitoringOccasionOfPO is present, the starting PDCCH monitoring occasion number of (i_s+ 1) th PO is the (i_s+ 1) th value of the firstPDCCH-MonitoringOccasionOfPO parameter; otherwise, it is equal to i_s*S*X. If X > 1, when the UE detects a PDCCH transmission addressed to P-RNTI within its PO, the UE is not required to monitor the subsequent PDCCH monitoring occasions for this PO.
[0042] Some examples of configuring paging occasions are given below.
[0043] Assuming the periodicity of the PDCCH monitoring occasions is 2 slots, Offset = 0, Duration = 2.
[0044] And assuming paging frame and paging occasion is for UE_ID = 2, the paging cycle is 32 radio frames, N is 4, and offset is 0. Ns is 4. And the parameter for starting symbol for each paging occasion is FirstPDCCH-MonitoringOccasionsofPO = {2, 15, 36, 45} .
[0045] (SFN + 0) mod 32 = (32 div 4) * (2 mod 4) = 16
[0046] System frame number SFN = 16, 48, 80, ... is the paging frame for the UE with UE_ID = 2.
[0047] i_s= floor (2 / 4) mod 2 = 0
[0048] Paging occasions for the UE with UE_ID 2 starts from the first paging occasion.
[0049] In SFN = 16, PDCCH monitoring occasion in one subframe is shown in FIG. 1.
[0050] There are 6 PDCCH monitoring occasions in one subframe in FIG. 1. Then we have 60 monitoring occasions in SFN = 16 in total.
[0051] Then, we also assume there are 8 synchronization signal blocks (SSBs) transmitted in a SSB burst, implying that there are 8 PDCCH monitoring occasions in one PO. As a result, the paging occasions (POs) for the UE with UE_ID 2 are shown in FIG. 2.
[0052] The solutions for energy saving based paging configurations and adaptation can be summarized as follows: energy saving based paging configurations; the condition for paging configuration adaptation; and the update period for paging configuration adaptation. An energy-saving paging configuration is shown in FIG. 3. The solutions include determining one or more paging occasions, according to a condition, where the one or more paging occasions include at least one of: a first type paging occasions or a second type paging occasions. The solutions further include monitoring a number of physical downlink control channel, PDCCH, monitoring candidates within one or more paging occasions. The solutions further include receiving a downlink control information, in a PDCCH monitoring candidate in the paging occasion within one or more paging occasions.
[0053] In some embodiments, a method of wireless communication includes determining, by a wireless device, one or more paging occasions according to a condition. In some embodiments, determining one or more paging occasions means the paging frame and paging occasion are determined.

[0062] As an alternative, the paging cycle is configured by the parameter ‘defaultPagingCycle’ in the RRC signaling ‘PCCH-config’ .
[0063] In this case, the paging cycle is denoted as T.
[0064] In some cases, an index for a first UE group for one UE is determined by a modulo between a UE identifier and a number of radio frame for paging.

And a value of ‘oneThirtytwoT’ corresponds to the number of frames for paging is 1 / 32 *T, a value of ‘oneSixtyfourT’ corresponds to the number of frames for paging is 1 / 64 *T and so on.

[0072] - 5G-S-TMSI mod 4096
[0073] or:

From base station perspective, paging frames are gathered in a relative short duration within one paging cycle, and deep sleep can be achieved by base station to obtain power saving gain in the remaining duration within one paging cycle.
[0084] In an embodiment, the offset information for paging occasion is determined based on an index for a second UE group, and the index for second UE group is determined based on a division between a UE identifier and a number of radio frames for paging with a floor operation.
[0085] In some cases, the offset information for paging occasion determines the paging occasion within the paging frame for one UE.
[0086] In some cases, the offset information is the index of the paging occasion, e.g., index (i_s) .
[0087] In some cases, the offset information for paging occasions is determined by an index for a second UE group and the number of paging occasions.
[0088] In this case, the offset information for paging occasions is determined by
[0089] i_s= floor (UE_ID / N) mod Ns, (5)

[0476] In some embodiments, there are one or more configuration adaptation information in the signaling.
[0477] In an embodiment, the signaling includes a higher layer parameter, a system information, a layer 2 signaling or a layer 1 signaling.
[0478] In an embodiment, one or more configuration adaptation information includes a first adaptation information.
[0479] In an embodiment, one or more configuration adaptation information includes a second adaptation information.
[0480] In an embodiment, one or more configuration adaptation information includes a first adaptation information and a second adaptation information.
[0481] In some embodiments, an application of the one or more configuration adaptation information is associated with an update period.
[0482] In an embodiment, the update period provides a number of radio frames, which is the length of the update period.
[0483] In an embodiment, the update period provides a number of seconds, which is the length of the update period.
[0484] In an embodiment, the update period provides a number of slots, which is the length of the update period.
[0485] In an embodiment, the update period provides a number of symbols, which is the length of the update period.
[0486] In an embodiment, the update period is K times a first periodicity, and where K is not smaller than 1.
[0487] In an embodiment, a starting point of the update period is determined by a system frame number value that satisfies SFN mod m = 0.
[0488] In some cases, the m is determined by the length of the update period.
[0489] In this case, the first configuration adaptation information is applied in the updated period when the one or more configuration adaptation information is received.
[0490] In this case, the second configuration adaptation information is applied in a next updated period after the updated period when the one or more configuration adaptation information is received.
[0491] For example, in FIG. 15, assuming there are two configuration adaptation information in the DCI signaling. The length of the updated period is 100 radio frames, i.e., m=100. SFN#0, SFN#100, SFN = 200, and so on are the starting point of update period. The first update period is from SFN#0~SFN#100, and the second updated period is from SFN#100~SFN#200 and so on. When the signaling is received in the first updated period, the first configuration adaptation information determines one or more paging occasions in the first updated period, while the second configuration adaptation information determines one or more paging occasions in the second updated period. This is helpful for UE to avoid ambiguity on paging configuration.
[0492] In an embodiment, a starting point of the update period is determined by a system frame number value that satisfies (SFN_counter*1024 + SFN) mod m = 0.
[0493] This formula can solve the problem when the update period is over SFN#1024, since in each 1024 radio frame, the SFN would be restart to 0.
[0494] For example, in FIG. 16, assuming the length of updated period is 100 radio frames. Then the updated period cross SFN#1024 remains 100 radio frames based on SFN_counter + 1.
[0495] In an embodiment, a starting point of the update period is determined by a reference point.
[0496] In some cases, the reference point includes a last radio frame of a configuration adaptation information reception.
[0497] In some cases, the reference point includes a first radio frame of a configuration adaptation information reception.
[0498] In some cases, the reference point includes a SFN satisfied (SFN+PF_offset) modT=0 that corresponds to the frame within the DRX cycle when the one or more configuration adaptation information is received.
[0499] In this case, the one or more configuration adaptation information being received includes the PDCCH providing the DCI format 2_7 being received.
[0500] In this case, the one or more configuration adaptation information being received includes the DCI format 1_0 with CRC scrambled by P-RNTI being received.

The formula can be (SFN+0) mod T = (UE_ID mod N) . And the formula for i_sis unchanged. The time duration can be used to repeat the pattern for the PF determined by the formula for SFN. gNB is capable of broadcasting a dedicated parameter to inform UE the available paging frame. The type of the dedicated parameter is bitmap, or offset, or specific SFN ID.
[0633] Feature 2 for the paging frame is described as follows. Only one paging frame exists for all UE. DCI based adaptation is described as follows.
