In these embodiments, the 5G core 114, the second interface 118, and/or the fifth interface 124 may be omitted.
In some embodiments, the network of the network environment 100 may comprise a NR dual connectivity (NR-DC) network. The NR-DC network may include the first base station 102, the second base station 104, and the 5G core 114. In the NR-DC network configuration, one of the first base station 102 or the second base station 104 may establish a connection to the 5G core 114 for both the control plane and the user plane, whereas the other of the first base station 102 or the second base station 104 may establish a connection to the 5G core 114 for only the user plane.

While some example embodiments of EN-DC, NE-DC, NR-DC, and NR-SA networks are described, it should be understood that the networks are not intended to be limited to these embodiments. In particular, the references to EN-DC, NE-DC, NR-DC, and NR-SA networks may include any EN-DC, NE-DC, NR-DC, and NR-SA network configurations known to a person having ordinary skill in the art (PHOSITA).
In some embodiments, the first base station 102 and the second base station 104 may comprise master nodes or secondary nodes. For example, in the EN-DC, NE-DC, and NR-DC network configurations described above where one of the first base station 102 or the second base station 104 establishes a connection for the control plane to the EPC 112 or the 5G core 114 and the other of the first base station 102 or the second base station 104 does not establish a connection for the control plane to the EPC 112 or the 5G core 114, the base station that establishes the control plane connection may be the master node and the base station that does not establish the control plane connection may be the secondary node. The master node may be part of a master cell group and the secondary node may be part of a secondary cell group.
In establishing connections with the base stations, the UE may have one of the first cell 106 or the second cell 108 as a primary cell (PCell) and the other of the first cell 106 or the second cell 108 as a secondary cell (SCell). The PCell and the SCell may operate on different frequencies and/or different frequency ranges (FRs). For example, the first cell 106, when acting as the PCell, may operate on a primary frequency or a primary FR, and the second cell 108, when acting as the SCell, may operate on a secondary frequency or a secondary FR. The primary frequency or primary FR may be a different frequency/FR from the secondary frequency or secondary FR.
The PCell and the SCell may provide component carriers (CCs) for the UE 110. For example, the network may configure the UE 110 with CCs from both the PCell and the SCell. The CCs for the UE 110 may include CCs of a primary frequency or primary FR from the PCell and CCs of a secondary frequency or secondary FR from the SCell. The PCell may provide a primary CC (PCC) for the UE 110 and the SCell may provide a secondary CC (SCC) for the UE 110. The SCC may be activated or deactivated at different times.
In NR standalone (SA), the interruption (caused by measurement of deactivated NR SCC) on NR active serving CCs was specified as (in TS 38.133 (3GPP Organizational Partners. (2020-09) 3rd Generation Partnership Project; Technical Specification Group Radio Access Network; NR; Requirements for support of radio resource management. (3GPP TS 38.133 V16.5.0)). For example, an interruption may be caused on NR active serving CCs by measurement of a deactivated NR SCC, where the NR active serving CCs and the deactivated NR SCC may be provided by NR base stations.
TS 38.133 Describes Interruptions During Measurements on Deactivated SCC as Follows. 8.2.2.2.3 of TS 38.133: Interruptions During Measurements on Deactivated SCC
Interruptions on PCell due to measurements when an SCell is deactivated are allowed with up to 0.5% probability of missed acknowledge (ACK)/negative acknowledge (NACK) when the configured measCycleSCell is 640 ms or longer. The UE is only allowed to cause interruptions immediately before and immediately after a SMTC. For example, the UE may only be allowed to cause interruptions immediately before or after a synchronization signal/physical broadcast channel-based radio resource management measurement time configure (SMTC) window. Each interruption shall not exceed requirement in Table 8.2.2.2.2-1 of TS 38.133 if the PCell is not in the same band as the deactivated SCell. Each interruption shall not exceed requirement in Table 8.2.2.2.2-2 of TS 38.133 if the PCell is in the same band as the deactivated SCell.
Interruptions on activated SCells due to measurements when an SCell is deactivated are allowed with up to 0.5% probability of missed ACK/NACK when the configured measCycleSCell is 640 ms or longer. The UE is only allowed to cause interruptions immediately before and immediately after an SMTC. For example, the UE may only be allowed to cause interruptions immediately before or after a SMTC window. Each interruption shall not exceed requirement in Table 8.2.2.2.2-1 of TS 38.133 if the activated SCell is not in the same band as the deactivated SCell. Each interruption shall not exceed requirement in Table 8.2.2.2.2-2 of TS 38.133 if the activated SCell is in the same band as the deactivated SCell.
In legacy EN-DC, the interruption (caused by measurement of deactivated LTE SCC) on NR active serving CCs was specified as (in TS 38.133):
8.2.1.2.5.2 of TS 38.133: Interruptions During Measurements on Deactivated E-UTRAN SCC
When one evolved universal terrestrial radio access (E-UTRA) SCell in MCG is deactivated, the UE is allowed due to measurements on the E-UTRA SCC with the deactivated E-UTRA SCell: an interruption on PSCell or any activated SCell with up to 0.5% probability of missed ACK/NACK when any of the configured measCycleSCell for the deactivated E-UTRA SCells is 640 ms or longer; an interruption on PSCell or any activated SCell with up to 0.5% probability of missed ACK/NACK regardless of the configured measCycleSCell for the deactivated E-UTRA SCells if indicated by the network using IE allowInterruptions.
The interruption requirement due to NR deactivated SCC measurement and interruption requirement due to LTE deactivated SCC measurement differs with respect to the supporting of allowInterruptions. This situation exists in NE-DC and NR-DC as well.
In summary, in EN-DC or NE-DC, the 0.5% interruption (to NR active serving CCs) caused by measurement on LTE deactivated SCC is only allowed when: measCycleSCell≥640 ms; measCycleSCell<640 ms but allowInterruptions=‘true’. In EN-DC, NE-DC, NR-SA and NR-DC, the 0.5% interruption (to NR active serving CCs) caused by measurement on NR deactivated SCC is only allowed when measCycleSCell≥640 ms.
The first interruption configuration 202 and the second interruption configuration 204 may both be for measurement periodicity of deactivated SCC (measCycleSCell) of greater than or equal to 640 milliseconds (ms). For the first interruption configuration 202, a UE may have interruption allowed and the UE may save power since the UE does not need to use radio frequency (RF) to cover CC2 (a deactivated SCC) outside the CC2 measurement occasion. For example, the UE may use RF that covers both CC1 (active serving CC) and CC2 at times, and may use RF that covers only CC1 at other times.
The first interruption configuration 202 has a first period 206, where the UE may use an RF that covers the CC1 (as indicated by rectangle with no fill for CC1) and does not cover CC2 (as indicated by the rectangle with dots for CC2). Not covering CC2 may use less power for the UE than covering both CC1 and CC2.
The first period 206 may conclude based on a first measurement of CC2. For example, a first measurement of CC2 may occur at the conclusion of the first period 206 in the first interruption configuration 202. The first measurement of the CC2 may initiate in a second period 208, where interruption occurs on both CC1 and CC2 (as indicated by the rectangles with the diagonal lines for CC1 and CC2). The interruption may be due to RF tuning/retuning or automatic gain control (AGC) settling. The AGC settling may apply when two CCs are intra-band. The interruption during the second period 208 may be for setting the UE to have RF that covers both CC1 and CC2 for the first measurement of CC2.
The second period 208 may be followed by a third period 210 where the UE may use an RF that covers both CC1 and CC2 (as indicated by the rectangles with cross-hatching for CC1 and CC2). During the second period 208 with the UE using an RF that covers both CC1 and CC2, the UE may perform a measurement on CC2.
The third period 210 may be followed by a fourth period 212 where another interruption occurs on both CC1 and CC2 (as indicated by the rectangles with the diagonal lines for CC1 and CC2). The interruption may be due to RF tuning/retuning or AGC setting. The interruption during the fourth period 212 may be for setting the UE to have an RF that covers CC1, but not CC2.
The fourth period 212 may be followed by a fifth period 214 where the UE may use an RF that covers the CC1 (as indicated by the rectangle with no fill for CC1), but not the CC2 (as indicated by the rectangle with dots for CC2). The fifth period 214 may occur after the first measurement of the CC2. A second measurement is shown in the first interruption configuration 202 after the fifth period 214, where the second measurement may have the interruptions and UE use an RF to cover both CC1 and CC2 as described for the first measurement.
For the second interruption configuration 204, the UE may not be allowed interruption caused by measurement on CC2. As the UE is not allowed interruption, the UE has to keep RF covering both CC1 (as indicated by the rectangle with no fill for CC1) and CC2 (as indicated by the rectangle with cross-hatching for CC2). The UE having to keep the RF to cover both CC1 and CC2 in the second interruption configuration 204 may consume more energy than the first interruption configuration 202 where interruption is allowed.
The indication and UE capability on LTE radio access technology (RAT) may need to be also extended to NR deactivated SCC measurement: per-UE indication between serving cell and UE for all NR operation modes; per-RAT indication between serving cell and UE for EN-DC and NE-DC. In particular, the introduction of NR deactivated SCC measurement may present issues that are to be addressed. How to interpret the different indication between two RATs may be an issue to be addressed. For the UE who support per-FR measurement gap (MG) capability, some exception cases may need to be added as well. Similar as LTE, two indications may be considered: (1) UE capability of whether it can benefit from reduced power consumption by allowing interruption for measCycleSCell<640 ms (indication from UE to network); (2) network indication to allow UE have interruption for measCycleSCell<640 ms (indication from network to UE).
The procedure 300 may include per-UE indication between UE and a network. For example, the procedure 300 may allow for per-UE indication between the UE and an EN-DC network, an NE-DC network, an NR-DC network, or an NR SA network (such as the EN-DC network, the NE-DC network, the NR-DC network, or the NR SA network described in relation to the network environment 100 (
The indication of UE capability on whether it can benefit from reduced power consumption by allowing interruption due to deactivated NR SCC measurement for measCycleSCell<640 ms. In particular, the procedure 300 may include providing an indication of UE capability of whether the UE can benefit from power consumption by allowing interruption due to deactivated NR SCC measurement for measCycleSCell less than 640 ms. The indication may be per-UE indication between PCell and UE for all NR operation modes. For example, the indication may be a per-UE indication provided by a UE to a PCell in the EN-DC network, the NE-DC network, the NR-DC network, or the NR-SA network. In EN-DC, UE may indicate this capability via LTE RRC to LTE PCell (extend the legacy capability signaling to support NR deactivated SCC measurement). For example, in the EN-DC network, the UE may provide the indication of the UE capability of whether the UE can benefit from power consumption by allowing interruption due to deactivated NR SCC measurement via LTE radio resource control (RRC) signaling to an LTE PCell. In NE-DC, NR-DC and NR-SA, UE may indicate this capability via NR RRC to NR PCell. For example, in the NE-DC network, the NR-DC network, and the NR-SA network, the UE may provide the indication of the UE capability of whether the UE can benefit from power consumption by allowing interruption due to deactivated NR SCC measurement via NR RRC signaling to an NR PCell.
The network indication to allow UE have interruption due to deactivated NR SCC measurement for measCycleSCell<640 ms. For example, the network may provide an indication to the UE indicating whether the UE is allowed to have interruption due to deactivated NR SCC measurement for measCycleSCell less than 640 ms. The network indication may be a per-UE indication between PCell and UE for all NR operation modes. For example, the indication may be a per-UE indication provided by a PCell to a UE in the EN-DC network, the NE-DC network, the NR-DC network, or the NR-SA network. In EN-DC, LTE PCell may indicate this signaling to UE via LTE RRC (extend the existing indication signaling to support NR deactivated SCC measurement). For example, in the EN-DC network, the LTE PCell may provide the indication of whether the UE is allowed to have the interruption via LTE RRC signaling to the UE. In NE-DC, NR-DC and NR-SA, NR PCell may indicate this signaling to UE via NR RRC. For example, in the NE-DC network, the NR-DC network, and the NR-SA network, the NR PCell may provide the indication of whether the UE is allowed to have the interruption via NR RRC signaling to the UE.
The procedure 300 may include providing an indication to a base station in 302. In particular, the UE may provide the indication to a base station (such as the first base station 102 (
In some embodiments, the base station may be an LTE base station and the indication may be provided to the LTE base station by LTE RRC signaling. Further, the LTE base station may be a master node or a secondary node of an EN-DC network (such as the EN-DC network described in relation to the network environment 100).
In other embodiments, the base station may be an NR base station and the indication may be provided to the NR base station by NR RRC signaling. Further, the NR base station may be a master node or a secondary node of an NE-DC network (such as the NE-DC network described in relation to the network environment 100), an NR-DC network (such as the NR-DC network described in relation to the network environment 100), or an NR-SA network (such as the NR-SA network described in relation to the network environment 100).
The procedure 300 may include determining whether to allow interruption in 304.

The UE 700 may not receive data in this state; in order to receive data, it must transition back to RRC_Connected state. An additional power saving mode may allow a device to be unavailable to the network for periods longer than a paging interval (ranging from seconds to a few hours). During this time, the device is totally unreachable to the network and may power down completely. Any data sent during this time incurs a large delay and it is assumed the delay is acceptable.
