Patent Description:
In <NUM> new radio (NR) DC, component carriers may be in a first frequency range (FR1) or a second frequency range (FR2). Typically, the FR1 frequency range is below <NUM> and the FR2 frequency range is in the mmWave frequency above <NUM>. When communicating with the <NUM> network, the UE may be configured with one or more bandwidth parts (BWPs) of FR1 and/or FR2 on which to communicate. <NPL>, provides discussions on the scaling factor CSSF for NR FR1+FR2 CA in both EN-DC and SA scenarios, and suggests the prioritization of PCC/PSCC over SCC when the scaling factor is applied. <NPL>, is a Change Request relating to the calculation of CSSF_outside_gap. <NPL>, relates to CSSF_outside_gap and provides views on the needed scaling factors for NE-DC.

Any embodiment that is not claimed is presented only as information.

The exemplary embodiments may be further understood with reference to the following description and the related appended drawings, wherein like elements are provided with the same reference numerals. The exemplary embodiments relate to a carrier specific scaling factor (CSSF) to be used for deactivated primary secondary cells (PSCells).

The exemplary embodiments are described with regard to a UE. However, the use of a UE is merely for illustrative purposes. The exemplary embodiments may be utilized with any electronic component that may establish a connection with a network and is configured with the hardware, software, and/or firmware to exchange information and data with the network. Therefore, the UE as described herein is used to represent any electronic component.

The exemplary embodiments are also described with regard to a network that includes <NUM> new radio NR radio access technology (RAT). However, in some embodiments, the network may also include a Long-Term Evolution (LTE) RAT and legacy RATs (e.g., CDMA, <NUM>, etc.). While the exemplary embodiments are described with reference to a <NUM> NR RAT, those skilled in the art will understand that other RATs may serve some of the component carriers (CCs) in an MR-DC arrangement.

In MR-DC, the UE may be configured with a primary cell group (PCG) and a secondary cell group (SCG). The PCG may include a primary cell (PCell) and one or more secondary cells (SCells) for communication between the UE and the <NUM> wireless network. The PCell serves a primary component carrier (PCC) and the SCells serve one or more secondary component carriers (SCCs). In addition, the SCG may include a primary secondary cell (PSCell) and one or more SCells for communication between the UE and the <NUM> wireless network. The PSCell serves a primary secondary component carrier (PSCC) and the SCells serve one or more SCCs. Because the UE only has a limited number of searchers (e.g., radiofrequency and baseband processing resources), the UE cannot simultaneously perform measurements on measurement objects (MOs) of all configured CCs during every monitoring occasion. These MOs may include synchronization signal block (SSBs), channel state information reference signals (CSI-RS), etc..

In Release <NUM> of the Third Generation Partnership (3GPP) standards, it is anticipated that the PSCell in the SCG will be allowed to be deactivated to provide energy saving at both the UE and network. However, the UE behavior in a deactivated PSCell needs to be defined. For example, when the PSCell is deactivated, the UE may not perform any Physical Downlink Control Channel (PDCCH) monitoring, Physical Downlink Shared Channel (PDSCH) reception, Physical Uplink Shared Channel (PUSCH) transmissions, beam management, etc..

In addition, Radio Resource Management (RRM) measurements on a deactivated serving cell (e.g., PSCell) may also be relaxed. Currently, there exists relaxed RRM measurements for a deactivated SCell compared with active serving cells. However, it is unlikely that the same measurement table can be used for measurement of a deactivated PSCell because the carrier specific scaling factor (CSSF) design for a PSCell and an SCell are quite different. PSCell measurements are prioritized over SCell measurements. If the same table is used, the same power saving cannot be achieved for the PSCell as that for the SCell.

According to the claimed implementation, the UE is configured to utilize a carrier specific scaling factor (CSSF) that allows searchers to be split equally among all the deactivated serving cells, including SCells and PSCells. For example, if the UE has two searchers, one searcher may be dedicated to measuring MOs of the PCC while the second searcher is divided among measurements of MOs of the PSCC and any configured SCCs.

In other exemplary embodiments, a new signaling may be introduced to allow prioritization of PSCell measurements over SCell measurements. For example, the PSCC may have a higher priority to the searcher that is used for the PSCC and SCCs. Each of these exemplary embodiments will be described in greater detail below.

<FIG> shows an exemplary network arrangement <NUM> according to various exemplary embodiments. The exemplary network arrangement <NUM> includes a UE <NUM>. It should be noted that any number of UE may be used in the network arrangement <NUM>. Those skilled in the art will understand that the UE <NUM> may alternatively be any type of electronic component that is configured to communicate via a network, e.g., mobile phones, tablet computers, desktop computers, smartphones, phablets, embedded devices, wearables, Internet of Things (IoT) devices, etc. It should also be understood that an actual network arrangement may include any number of UE being used by any number of users. Thus, the example of a single UE <NUM> is merely provided for illustrative purposes.

The UE <NUM> may be configured to communicate with one or more networks. In the example of the network configuration <NUM>, the networks with which the UE <NUM> may wirelessly communicate are a <NUM> New Radio (NR) radio access network (<NUM> NR-RAN) <NUM>, an LTE radio access network (LTE-RAN) <NUM> and a wireless local access network (WLAN) <NUM>. However, it should be understood that the UE <NUM> may also communicate with other types of networks and the UE <NUM> may also communicate with networks over a wired connection. Therefore, the UE <NUM> may include a <NUM> NR chipset to communicate with the <NUM> NR-RAN <NUM>, an LTE chipset to communicate with the LTE-RAN <NUM> and an ISM chipset to communicate with the WLAN <NUM>.

The <NUM> NR-RAN <NUM> and the LTE-RAN <NUM> may be portions of cellular networks that may be deployed by cellular providers (e.g., Verizon, AT&T, T-Mobile, etc.). These networks <NUM>, <NUM> may include, for example, cells or base stations (Node Bs, eNodeBs, HeNBs, eNBS, gNBs, gNodeBs, macrocells, microcells, small cells, femtocells, etc.) that are configured to send and receive traffic from UE that are equipped with the appropriate cellular chip set. The WLAN <NUM> may include any type of wireless local area network (WiFi, Hot Spot, IEEE <NUM>. 11x networks, etc.).

The UE <NUM> may connect to the <NUM> NR-RAN <NUM> via the gNB 120A and/or the gNB 120B. The gNBs 120A and 120B may be configured with the necessary hardware (e.g., antenna array), software and/or firmware to perform massive multiple in multiple out (MIMO) functionality. Massive MIMO may refer to a base station that is configured to generate a plurality of beams for a plurality of UE. During operation, the UE <NUM> may be within range of a plurality of gNBs. Thus, either simultaneously or alternatively, the UE <NUM> may connect to the <NUM> NR-RAN <NUM> via the gNBs 120A and 120B. In the present example, it may be considered that the gNB 120A is part of a PCG and the gNB 120B is part of SCG. Thus, in DC operation, the UE <NUM> may be simultaneously connected to gNB <NUM> A (PCG) and gNB 120B (SCG). In this example, it may be considered that the gNB 120A is the PCell and the gNB 120B is the PSCell. Reference to two gNBs 120A, 120B is merely for illustrative purposes. The exemplary embodiments may apply to any appropriate number of gNBs. Further, the UE <NUM> may communicate with the eNB 122A of the LTE-RAN <NUM> to transmit and receive control information used for downlink and/or uplink synchronization with respect to the <NUM> NR-RAN <NUM> connection.

Those skilled in the art will understand that any association procedure may be performed for the UE <NUM> to connect to the <NUM> NR-RAN <NUM>. For example, as discussed above, the <NUM> NR-RAN <NUM> may be associated with a particular cellular provider where the UE <NUM> and/or the user thereof has a contract and credential information (e.g., stored on a SIM card). Upon detecting the presence of the <NUM> NR-RAN <NUM>, the UE <NUM> may transmit the corresponding credential information to associate with the <NUM> NR-RAN <NUM>. More specifically, the UE <NUM> may associate with a specific base station (e.g., the gNB 120A of the <NUM> NR-RAN <NUM>).

In addition to the networks <NUM> and <NUM> the network arrangement <NUM> also includes a cellular core network <NUM>. The cellular core network <NUM> may be considered to be the interconnected set of components that manages the operation and traffic of the cellular network.

<FIG> shows an exemplary UE <NUM> according to various exemplary embodiments. The UE <NUM> will be described with regard to the network arrangement <NUM> of <FIG>. The UE <NUM> may represent any electronic device and may include a processor <NUM>, a memory arrangement <NUM>, a display device <NUM>, an input/output (I/O) device <NUM>, a transceiver <NUM> and other components <NUM>. The other components <NUM> may include, for example, an audio input device, an audio output device, a battery that provides a limited power supply, a data acquisition device, ports to electrically connect the UE <NUM> to other electronic devices, one or more antenna panels, etc. For example, the UE <NUM> may be coupled to an industrial device via one or more ports.

The processor <NUM> may be configured to execute a plurality of engines of the UE <NUM>. For example, the engines may include a radio resource management (RRM) engine <NUM>. The RRM engine <NUM> may perform various operations related to management of measurements of multiple configured MOs for a deactivated PSCell.

The above referenced engine being an application (e.g., a program) executed by the processor <NUM> is only exemplary. The functionality associated with the engine may also be represented as a separate incorporated component of the UE <NUM> or may be a modular component coupled to the UE <NUM>, e.g., an integrated circuit with or without firmware. For example, the integrated circuit may include input circuitry to receive signals and processing circuitry to process the signals and other information. The engines may also be embodied as one application or separate applications. In addition, in some UE, the functionality described for the processor <NUM> is split among two or more processors such as a baseband processor and an applications processor. The exemplary embodiments may be implemented in any of these or other configurations of a UE.

The memory arrangement <NUM> may be a hardware component configured to store data related to operations performed by the UE <NUM>. The display device <NUM> may be a hardware component configured to show data to a user while the I/O device <NUM> may be a hardware component that enables the user to enter inputs. The display device <NUM> and the I/O device <NUM> may be separate components or integrated together such as a touchscreen. The transceiver <NUM> may be a hardware component configured to establish a connection with the <NUM> NR-RAN <NUM>, the LTE-RAN <NUM>, the WLAN <NUM>, etc. Accordingly, the transceiver <NUM> may operate on a variety of different frequencies or channels (e.g., set of consecutive frequencies).

<FIG> shows an exemplary network base station according to various exemplary aspects. As noted above with regard to the network arrangement <NUM> of <FIG>, in this example, the gNB 120A may represent the PCell of the PCG and the gNB 120B may represent the PSCell for the SCG. The gNB 120A may represent any access node of the <NUM> NR network through which the UE <NUM> may establish a connection and manage network operations as a PCell. The gNB 120A illustrated in <FIG> may also represent the gNB 120B. In this example, it will be assumed that the control information that is sent to the UE <NUM> to configure the UE <NUM> for RRM measurements on a deactivated PSCell is sent by the PCell (e.g., gNB 120A). However, it should be understood that any gNB of the network may send the configuration information to the UE <NUM>.

The gNB 120A may include a processor <NUM>, a memory arrangement <NUM>, an input/output (I/O) device <NUM>, a transceiver <NUM>, and other components <NUM>. The other components <NUM> may include, for example, an audio input device, an audio output device, a battery, a data acquisition device, ports to electrically connect the gNB 120A to other electronic devices, etc..

The processor <NUM> may be configured to execute a plurality of engines of the gNB 120A. For example, the engines may include a radio resource management (RRM) engine <NUM>. The RRM engine <NUM> may perform various operations related to management of measurements of multiple configured MOs. Specifically, as described above, the RRM engine <NUM> may configure the UE to perform RRM measurements on a deactivated PSCell. Examples of these operations will be described in greater detail below.

The above noted engines each being an application (e.g., a program) executed by the processor <NUM> is only exemplary. The functionality associated with the engines may also be represented as a separate incorporated component of the gNB 120B or may be a modular component coupled to the gNB 120A, e.g., an integrated circuit with or without firmware. For example, the integrated circuit may include input circuitry to receive signals and processing circuitry to process the signals and other information. In addition, in some gNBs, the functionality described for the processor <NUM> is split among a plurality of processors (e.g., a baseband processor, an applications processor, etc.). The exemplary aspects may be implemented in any of these or other configurations of a gNB.

The memory <NUM> may be a hardware component configured to store data related to operations performed by the UEs <NUM>, <NUM>. The I/O device <NUM> may be a hardware component or ports that enable a user to interact with the gNB 120A. The transceiver <NUM> may be a hardware component configured to exchange data with the UEs <NUM> and any other UE in the system <NUM>. The transceiver <NUM> may operate on a variety of different frequencies or channels (e.g., set of consecutive frequencies). Therefore, the transceiver <NUM> may include one or more components (e.g., radios) to enable the data exchange with the various networks and UEs.

<FIG> shows a method <NUM> of performing radio resource management (RRM) according to various exemplary embodiments. At <NUM>, the UE <NUM> receives a CC configuration for NR-DC communications from a gNB (e.g., gNB 120A or 120B). As described above, the CC configuration may include a PCC served by a PCell and a PSCC served by a PSCell. The PCC and the PSCC may be in in FR1 and/or FR2, although typically the PCC will be in FR1. The CC configuration may additionally include SCCs from the PCG and/or the SCG. At <NUM>, the UE <NUM> receives an MO configuration for the CCs configured at <NUM>. As noted above, the UE <NUM> cannot measure all MOs corresponding to the configured CCs simultaneously. As such, at <NUM>, the UE <NUM> determines a CSSF based on the MO configuration. This CSSF is determined based on Tables <NUM> and <NUM> illustrated in <FIG> and <FIG>, respectively. The CSSF dictates which CC's MO the UE <NUM> will measure at a given time. In other words, the CSSF is a scaling factor applied to the measurement period of the corresponding MO.

Those skilled in the art will understand that the method <NUM> is only exemplary and the operations described for the method <NUM> may be performed in another order. For example, in some exemplary embodiments, the operations <NUM> and <NUM> may be reversed.

<FIG> shows a table for determining a carrier specific scaling factor (CSSF) for deactivated serving cells where a second searcher is allocated evenly among the serving cells according to various exemplary embodiments. The table <NUM> allows the searchers to be split equally among all the deactivated serving cells, including SCell and PSCell. The table <NUM> assumes that the PCC is in FR1 (below <NUM>) and the PSCC is in FR2 (above <NUM>).

The CSSF outside of the measurement gap (MG) for the FR1 PCC is equal to the number of MOs configured for the PCC, which is <NUM> + NPCC_CSIRS. As noted in Note <NUM>, if no CSI-RS MO is configured for the PCC, then the CSSF outside of the measurement gap for the FR1 PCC is equal to <NUM>. Otherwise, it is equal to <NUM> (<NUM> + <NUM>). The CSSF of the FR1 PCC is always at least one because, as noted above, one of the searchers of the UE <NUM> is always dedicated to measuring the MOs of the PCC. As also noted in Note <NUM>, NPCC_CSIRS is equal to <NUM> if either the SSB and CSI-RS based layer <NUM> (L3) measurements are both configured for the PCC or if only the CSI-RS based L3 measurement is configured for the PCC (since an SSB is needed to schedule the CSI-RS).

As described above, in accordance with the claimed embodiment, the second searcher of the UE <NUM> is split equally among the PSCC and any SCCs. The CSSF outside of the measurement gap for the FR2 PSCC is defined as 2x(the number of MOs on the PSCC and on the inter-frequency layer without measurement gap), which is described by the equation 2x (NSCC_SSB + Y + NPSCC_CSIRS), where Y is the number of configured inter-frequency SSB-based frequency layers without measurement gap that are being measured outside of the measurement gap (as indicated in Note <NUM>). Note <NUM> is similar to Note <NUM> discussed above with the exception that Note <NUM> pertains to NPSCC_CSIRS. Note <NUM> indicates that if no SCCs are configured and no inter-frequency MO without measurement gap is configured, then the CSSF outside of the measurement gap for the FR2 PSCC is equal to <NUM>. This means that there are no other MOs that need to share the UE's second searcher with the PSCC. In this case, the first searcher is dedicated to the PCC MOs and the second searcher is used to measure PSCC MOs.

The CSSF outside of the measurement gap for configured SCCs in FR1 is defined as 2x(the number of MOs on all SCCs and on the inter-frequency layer without measurement gap) on any SCC, which is described by the equation 2x(NSCC_SSB + Y + NSCC_CSIRS), where Y has been defined above. As indicated in Note <NUM>, NSCC_CSIRS is the number of configured SCells and PSCells with either (a) both SSB and CSI-RS based L3 measurements configured or (b) only a CSI-RS based L3 measurement configured. As indicated in Note <NUM>, NSCC_SSB is the number of configured SCells and PSCells with only an SSB based L3 measurement configured.

As can be seen from table <NUM>, the equations for the CSSF outside of the measurement gap for FR2 for configured SCCs where neighbor cell measurement is not required and the CSSF outside of the measurement gap for inter-frequency MOs with no measurement gaps are identical to the CSSF outside of the measurement gap for configured SCCs in FR1 as described above. Thus, as can be seen from the table <NUM>, the searchers are split equally among all the deactivated serving cells.

<FIG> shows an exemplary searcher allocation <NUM> when the searchers are split equally among all the deactivated serving cells according to various exemplary embodiments. The searcher allocation <NUM> is based on the table <NUM> of <FIG>. In this example, it may be considered that the UE <NUM> is configured with a PCC <NUM>, a PSCC <NUM>, and three SCCs <NUM>-<NUM>. The UE <NUM> is also configured with the timing of SSBs using a SS/PBCH Block Measurement Timing Configuration (SMTC) for each CC. In this example, each CC is shown as including ten (<NUM>) SMTCs. In this example, each SMTC for each CC is shown as having the same time and periodicity for convenience in illustration. Those skilled in the art will understand that typically the SMTC periodicity on the SCCs <NUM>-<NUM> is longer than the PCC <NUM> and the PSCC <NUM>. Thus, with less measurement on PSCC <NUM>, the UE <NUM> may experience power saving on the SMTC occasion on the PSCC <NUM> when there is no overlapped SMTC on the SCCs <NUM>-<NUM>.

As described above, a first searcher (searcher <NUM><NUM>) is dedicated to the PCC <NUM>. Thus, searcher <NUM><NUM> is used for all SMTC occasions for the PCC <NUM> as shown in <FIG>.

In contrast, a second searcher (searcher <NUM><NUM>) is split among the PSCC <NUM> and the SCCs <NUM>-<NUM>. As described above, the table <NUM> results in a CSSF where the searcher <NUM><NUM> is split equally among all the deactivated serving cells, e.g., PSCC <NUM> and SCCs <NUM>-<NUM>. Thus, the first instance of searcher <NUM><NUM>(<NUM>) is for the PSCC <NUM>, the second instance of the searcher <NUM><NUM>(<NUM>) is for the SCC <NUM>, the third instance of the searcher <NUM><NUM>(<NUM>) is for the SCC <NUM>, and the fourth instance of the searcher <NUM><NUM>(<NUM>) is for the SCC <NUM>. The searcher <NUM><NUM> will then cycle through the PCC <NUM> and the SCCs <NUM>-<NUM> equally as shown in <FIG>. As described above, the timing and periodicity of the SMTCs for the PSCC <NUM> and the SCCs <NUM>-<NUM> may vary and therefore, the power saving may be increased because the UE <NUM> may spend less time measuring deactivated cells.

In other exemplary embodiments, new signaling may be introduced to allow prioritization of PSCell measurements over SCell measurements. The signaling may be radio resource control (RRC) signaling, Medium Access Control Control Element (MAC-CE) signaling, etc. The prioritization may be based on an allocation of the second searcher to the PSCell. For example, RPSCC may represent the ratio of the second searcher allocation for PSCell and SCells. The prioritization factor for the allocation may be any value between <NUM> and <NUM> (e.g., <NUM>% - <NUM>%). The following examples will assume the value of <NUM> (or <NUM>%). However, as stated above, the allocation may take on any value and those skilled in the art will understand how to apply the allocation based on the below examples.

<FIG> shows a table <NUM> for determining a CSSF for deactivated serving cells where a second searcher is allocated based on a prioritization of a PSCell according to various exemplary embodiments. The table <NUM> allows the second searcher to be allocated based on an allocation that may prioritize the deactivated PSCell over SCells. Again, the table <NUM> assumes that the PCC is in FR1 (below <NUM>) and the PSCC is in FR2 (above <NUM>).

As described above with respect to table <NUM>, the CSSF outside of the measurement gap (MG) for the FR1 PCC is equal to the number of MOs configured for the PCC, which is <NUM> + NPCC_CSIRS. Thus, the allocation for the PCC is the same as was described above and will not be described again.

The CSSF outside of the measurement gap for the FR2 PSCC is described by the equation f (RPSCC)×(<NUM>×(NSCC_SSB + Y + <NUM>×NPSCC_CSIRS), where f(RPSCC) is a function based on the ratio of the second searcher allocation to the PSCC. Examples of this function will be provided below. The remaining parameters in the equation were described above with reference to table <NUM> and will not be described again.

The CSSF outside of the measurement gap for configured SCCs in FR1 is described by the equation g(RPSCC)× <NUM>×(NSCC_SSB + Y + NSCC_CSIRS), where g(RPSCC) is a function based on the ratio of the second searcher allocation to the PSCC. The remaining parameters in the equation were described above with reference to table <NUM> and will not be described again.

As can be seen from table <NUM>, the equations for the CSSF outside of the measurement gap for FR2 for configured SCCs where neighbor cell measurement is not required and the CSSF outside of the measurement gap for inter-frequency MOs with no measurement gaps are identical to the CSSF outside of the measurement gap for configured SCCs in FR1 as described above.

As shown in table <NUM>, the functions f(RPSCC) and g(RPSCC) are used to determine the scaling factor CSSF for SCCs and a deactivated PSCC, based on the configured ratio RPSCC. The following provides examples of the functions based on the prioritization factor being <NUM>%. In a first example, f(RPSCC) = <NUM>/RPSCC and g(RPSCC) = <NUM>/(<NUM>-RPSCC). Thus, the scaling factors will allocate <NUM>% of the second searcher to the PSCC and the remaining <NUM>% to the SCCs.

In a second example, it is understood that based on the number of PSCCs and SCCs, the functions may result in a non-integer value. Thus, in the second example, the scale is based on a <NUM>% prioritization factor and then a ceil function to an integer value as follows: f(RPSCC) = ceil(<NUM>/RPSCC) and g(RPSCC) = ceil(<NUM>/(<NUM>-RPSCC)).

In a third example, the scale is based on a <NUM>% prioritization factor and then a ceil function of the entire CSSF equation to an integer value. For example, for the PSCC, the equation is: CSSFPSCC = ceil(f(RPSCC) ×<NUM>×(<NUM>+ NPSCC_CSIRS)) = ceil((<NUM>/RPSCC)×<NUM>×(<NUM>+ NPSCC_CSIRS)).

The actual format of the CSSF in the table <NUM> may be any mathematical transformation of above equation. For example, for the PSCC: ceil((<NUM>/RPSCC)×<NUM>×(<NUM>+ NPSCC_CSIRS)) = ceil(RPSCC×(<NUM>+ NPSCC_CSIRS)); then f(RPSCC) = RPSCC. The physical meaning of the CSSF assumption of the UE measurement behavior (e.g., the measurement time and the periodicity) remains the same as was described above. Thus, from these examples it may be seen how to generate the CSSF for other cases, e.g., for a PSCC allocation of <NUM>%, <NUM>%, etc..

As described above, the prioritization of the PSCell measurements over the SCell measurements may be signaled to the UE via new signaling. <FIG> shows an example of a MeasConfig Information Element (IE) <NUM> that includes the prioritization information according to various exemplary embodiments. As shown in <FIG>, a new parameter RatioPSCC <NUM> may be added to the MeasConfig IE <NUM> to signal the prioritization information. In this example, the prioritization factor is limited to the enumerated list of dot25, dot50, dot75 (e.g., <NUM>%, <NUM>%, <NUM>%, respectively). However, this is only exemplary as other values of the prioritization factor may be used.
