Description

[Technical Field]

[0001] Various exemplary embodiments of the present disclosure relate generally to the field of telecommunications, and more particularly to methods, devices, apparatus, and computer-readable storage media for controlling processes toward cells with extended duplex operation. [Background technology]

[0002] Currently, New Radio (NR) supports two duplex modes: Frequency Division Duplex (FDD) for paired bands and Time Division Duplex (TDD) for unpaired bands. In TDD, time domain resources are divided between downlink (DL) and uplink (UL). The allocation of limited duration for the uplink in TDD results in reduced coverage, increased latency, and reduced capacity.

[0003] To address these challenges, research has begun into the evolution of duplexing operation in NR. Subband non-overlapping full duplex (SBFD) has been proposed as an extended duplex operation method. SBFD allows simultaneous DL transmission and UL reception at an NR Node B (also known as gNB) on different physical resource blocks (PRBs) within an unpaired wideband NR cell. This duplexing method is also known as cross-division duplex (xDD) or flexible duplex (FDU). Summary of the Invention

Given the rapid development of communications, there will naturally be future types of communication technologies and systems in which the present disclosure may be embodied. This should not be understood as limiting the scope of the present disclosure to only the aforementioned systems.

[0025] As used herein, the term "network device" refers to a node in a communication network through which a terminal device accesses the network and receives services therefrom.

[0027] As used herein, a "set of elements" means one or more such elements. For example, a set of values ​​means one or more values. Similarly, a parameter set may comprise one or more parameters.

[0028] As used herein, the term "extended duplex operation" may refer to any suitable duplex scheme that differs from traditional TDD and FDD. Extended duplex operation may involve simultaneous reception and transmission by a network device in an unpaired frequency band. Examples of extended duplex operation may include, but are not limited to, SBFD, dynamic or flexible TDD. Hereinafter, the term "extended duplex operation" is used for descriptive purposes without any limitation on the scope of protection. Example embodiments described herein with respect to extended duplex operation may be applied to any suitable type of duplex operation.

[0029] 1 illustrates an exemplary communication environment 100 in which exemplary embodiments of the present disclosure may be implemented. Communication environment 100 includes first device 110-1 and first device 110-2, collectively referred to as "first device" 110 or individually referred to as "first device" 110. First device 110 may communicate with second device 120. A serving area of ​​second device 120 is referred to as a cell. Second device 120 may serve one or more cells, e.g., cell 102. In some exemplary embodiments, first device 110 may comprise a terminal device, and second device 120 may comprise a network device serving the terminal device.

[0030] For purposes of illustration, some exemplary embodiments are described below with first device 110 operating as a terminal device and second device 120 operating as a network device. However, in some exemplary embodiments, operations described with reference to a terminal device may be implemented in a network device or other device, and operations described with reference to a network device may be implemented in a terminal device or other device.

[0031] In some demonstrative embodiments, when the first device 110 is a terminal device and the second device 120 is a network device, the link from the second device 120 to the first device 110 is called a downlink (DL), and the link from the first device 110 to the second device 120 is called an uplink (UL). In the DL, the second device 120 is a transmit (TX) device (or transmitter), and the first device 110 is a receive (RX) device (or receiver). In the UL, the first device 110 is a TX device (or transmitter), and the second device 120 is a RX device (or receiver).

[0032] Communications in communication environment 100 may be implemented according to any suitable communications protocol, including, but not limited to, cellular communications protocols such as first generation (1G), second generation (2G), third generation (3G), fourth generation (4G), fifth generation (5G), sixth generation (6G), wireless local network communications protocols such as IEEE (Institute for Electrical and Electronics Engineers) 802.11, and / or any other protocols now known or developed in the future. Furthermore, communications may utilize any suitable wireless communications technology, including, but not limited to, code division multiple access (CDMA), frequency division multiple access (FDMA), time division multiple access (TDMA), frequency division duplex (FDD), time division duplex (TDD), multiple input multiple output (MIMO), orthogonal frequency division multiple access (OFDM) discrete Fourier transform spread OFDM (DFT-s-OFDM), and / or any other technology now known or developed in the future.

[0033] The cell 102 is capable of extended duplex operation, i.e., the cell 102 supports extended duplex operation. Hereinafter, a cell capable of extended duplex operation or a cell capable of extended duplex operation may also be referred to as an ED cell. For example, extended duplex operation may include SBFD operation, and the cell 102 is accordingly an SBFD cell. Note that SBFD operation is an example of extended duplex operation. In exemplary embodiments of the present disclosure, the extended duplex operation may comprise any suitable type of duplex operation other than conventional TDD operation and FDD operation. In another example, the extended duplex operation may comprise dynamic TDD operation.

[0034] In some exemplary embodiments, the environment 100 may include cells 103 that do not have extended duplex operation capability, in other words, the cells 103 cannot support extended duplex operation. For example, the cells 103 may not have the capability for SBFD operation. Hereinafter, cells that do not have the capability for extended duplex operation may also be referred to as legacy cells. That is, ED cells and legacy cells may coexist in the environment 100. However, this is an example. Alternatively, in some exemplary embodiments, all cells may support extended duplex operation.

[0035] In some demonstrative embodiments, environment 100 may comprise a cell 104 that is served by another device different from second device 120. Cell 104 may be an adjacent cell.

[0036] The first device 110-1 supports extended duplex operation, which may mean that the first device 110-1 recognizes that a second device (e.g., a network device) is capable of extended duplex operation. The first device 110-1 is also referred to as an ED-capable device or an ED-aware device. The first device 110-2 is also referred to as a legacy device because it does not support extended duplex operation. In an example, the extended duplex operation may comprise SBFD operation. Thus, the first device 110-1 may be an SBFD-aware device, and the first device 110-2 may be a legacy device.

[0037] It should be understood that communication environment 100 is provided for illustrative purposes without any limitation on the scope of protection, and may include any suitable number of devices and cells configured to implement the exemplary embodiments of the present disclosure.

[0038] Consider SBFD as an example of enhanced duplex operation. SBFD cells are expected to coexist with legacy cells, e.g., other cells that support only conventional TDD operation from both co-channel (i.e., cells deployed on the same carrier frequency, e.g., belonging to the same operator) and adjacent channel perspectives (i.e., cells deployed on adjacent carriers, e.g., belonging to different operators). Furthermore, existing UEs that cannot be upgraded to support SBFD-specific features can also be served on SBFD cells. It is desirable that these UEs do not experience significant performance degradation compared to, e.g., performance in legacy TDD cells. That is, backward compatibility in SBFD cells must be ensured.

[0039] In another aspect, during a cell selection or cell reselection process, a UE scans and measures signals on one or more radio frequencies to select and camp on a suitable serving cell and / or to determine whether to reselect from its current serving cell to another cell as its new serving cell. For example, the UE may measure signals from a cell by measuring Reference Signal Received Power (RSRP) and / or Reference Signal Received Quality (RSRQ). One or more signal parameters of the signals received from the cell may be measured at the UE, and a cell selection (or reselection) value for the cell may be determined based on such signal parameters and one or more network-configured offsets and / or reselection priorities. If the measured signals meet predetermined criteria, the UE can select and / or reselect the corresponding cell. The selection and / or reselection criteria may be adjusted based on UE capabilities and whether the cell serves a particular application.

[0040] The absolute priorities of the different frequencies are provided to the UE in system information or a radio resource control (RRC) message, e.g., an RRCRelease message. The UE shall perform cell reselection evaluation based on the frequency priorities given in the system information.

[0041] An SBFD cell can simultaneously perform DL Tx and UL Rx on non-overlapping PRBs while the UE is still operating in half-duplex (HD) mode. When an SBFD cell is serving both legacy and SBFD-aware UEs, to simplify the gNB implementation and / or limit the impact on the performance of legacy UEs, the SBFD cell may prefer to schedule only legacy UEs in downlink-only and uplink-only slots, but SBFD-aware UEs may also be scheduled during SBFD slots.

[0042] Therefore, an SBFD cell may be in a situation where allowing access to a legacy UE may require reconfiguring one or more SBFD slots as TDD (DL) slots. However, the gNB may wish to operate with a given number of slots configured as SBFD slots to guarantee minimum uplink capacity and / or coverage. It may also occur that a cell's TDD UL resources are close to full utilization, but the cell's SBFD UL resources are still partially unused.

[0043] In any of the above situations, an SBFD cell may want to prevent access from legacy devices, but may not want to prevent access from SBFD-aware UEs. In other words, after SBFD is introduced, if there are available cells that do not utilize SBFD, it may be desirable to prevent legacy UEs from camping on the SBFD cell. Therefore, it is desirable to distinguish between the behavior of a legacy UE and the behavior of an SBFD-aware UE with respect to the process of heading toward an SBFD cell, e.g., cell selection or cell reselection toward an SBFD cell.

[0044] A solution is proposed to provide an SBFD-aware UE with an indication of the cell's duplex operation mode to facilitate the SBFD-aware UE's selection of an SBFD cell. However, this solution cannot distinguish between the behavior of legacy UEs and that of SBFD-aware UEs. Similar problems may arise for other types of extended duplex operation, such as dynamic TDD.

[0045] According to some example embodiments of the present disclosure, a solution is provided for controlling processes toward a cell having extended duplex operation. In this solution, two different sets of values ​​for a parameter set associated with the cell are configured. ED-aware devices may apply one set of values ​​to processes toward the cell. Legacy devices may apply the other set of values ​​to processes toward the cell.

[0046] In an exemplary embodiment of the present disclosure, the ED-aware device and the legacy device apply different sets of parameter values ​​to the process of heading to the ED cell. In this way, the behavior of the legacy device can be distinguished from the behavior of the ED-aware device with respect to the process of heading to the ED cell. For example, by controlling two sets of values, the legacy device can be prevented from determining the ED cell as a target cell while the ED-aware device is still allowed to camp on or access the ED cell.

[0047] Preferred embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0048] 2 illustrates a signaling chart 200 for controlling a process toward a cell, in accordance with some exemplary embodiments of the present disclosure. As shown in FIG. 2, the signaling chart 200 includes a first device 110 and a second device 120. For purposes of explanation, reference is made to FIG. 1 to describe the signaling chart 200. While one first device 110 is shown in FIG. 2, it will be appreciated that there may be multiple first devices performing operations similar to those described below with respect to the first device 110.

[0049] In some demonstrative embodiments, second device 120 may determine whether a cell is capable of extended duplex operation 205. For example, in a mixed deployment scenario where a subset of cells on a frequency layer have SBFD capability, second device 120 may determine whether a particular cell is an ED cell 205. In another example, for each cell of a group of cells (e.g., a group of neighboring cells), second device 120 may determine whether the cell is an ED cell 205.

[0050] It should be understood that the cell may be a cell served by the second device 120, e.g., cell 102 shown in Figure 1. Alternatively, or in addition, the cell may be a cell served by another device, e.g., cell 104 shown in Figure 1. In such cases, the cells may be neighboring cells.

[0051] If the second device 120 determines that the cell is not capable of extended duplex operation, the second device 120 may transmit 210 a first set of values ​​for the parameter set to the first device 110. The parameter set is associated with a process toward the cell. For example, for a cell 103 that is not an ED cell, the second device 120 may transmit 210 a first set of values ​​for the parameter set associated with a process toward the cell 103 to the first device 110.

[0052] If the second device 120 determines that the cell has extended duplex operation capability, the second device 120 may transmit (220) at least a second set of values ​​for the parameter set to the first device 110. For example, for cell 102 that is an ED cell, the second device 120 may transmit to the first device 110 at least a second set of values ​​for the parameter set related to processes toward the cell 120. It should be understood that the second set of values ​​may be configured to control processes of an ED-aware device toward a cell with extended duplex operation capability.

[0053] In some demonstrative embodiments, only the second set of values ​​may be transmitted without the first set of values. For example, if second device 120 recognizes that first device 110 is an ED-aware device, second device 120 may transmit the second set of values ​​without the first set of values.

[0054] Alternatively, in some demonstrative embodiments, second device 120 may transmit both the first set of values ​​and the second set to first device 110. For example, if second device 120 does not know whether first device 110 supports extended duplex operation, or if the first and second sets of values ​​are broadcast to multiple first devices including devices that support ED operation and devices that do not support ED operation, second device 120 may transmit both the first and second sets of values.

[0055] The first set of values ​​and / or the second set of values ​​may be transmitted in any suitable signaling, e.g., broadcast in a system information block (SIB) or in dedicated signaling (such as an RRC message). If both the first set of values ​​and the second set are transmitted to the first device 110, they may be transmitted separately or, for example, transmitted together in the same signaling.

[0056] In some demonstrative embodiments, operation 205 may be omitted, and the second device 120 may transmit at least one of the first set of values ​​and the second set of values ​​for the parameter set to the first device 110. For example, for cells capable of extended duplex operation, the second device 120 may transmit at least the second set of values ​​to the first device 110, and for cells without that capability, the second device 120 may transmit the first set of values ​​to the first device 110. As another example, in a deployment scenario where all cells have SBFD capability, determining the cell's capability may be unnecessary. In a further example, for cell selection purposes, for cells of the second device 120 capable of extended duplex operation, the second device 120 may transmit at least the second set of values ​​without determining that capability. This is because the second device 120 knows the capability of its own cell in advance.

[0057] In some exemplary embodiments, the second set of values ​​may result in a different likelihood of determining a cell as a target cell compared to the first set of values. In this manner, the behavior of ED-aware devices and legacy devices may be distinguished. Further, in some exemplary embodiments, the second set of values ​​may result in a higher likelihood of determining a cell as a target cell compared to the first set of values. In this manner, ED-aware devices may be facilitated to camp on or access ED cells, and / or legacy devices may be prevented or blocked from camping on or accessing ED cells.

[0058] In some exemplary embodiments, the parameter set associated with the process toward the cell may comprise one or more parameters specific to the cell. In some exemplary embodiments, the parameter set may comprise parameters for a group of cells that includes the cell. For example, the parameter set may comprise a priority for reselecting a target cell from a group of cells that includes the cell.

[0059] One or more parameters included in the parameter set may depend on a process towards the cell. In some exemplary embodiments, the process towards the cell may include a cell selection process towards the cell. The parameter set may include one or more parameters (e.g., one or more offsets) related to the cell selection process. Alternatively, or in addition, the process towards the cell may comprise a cell reselection process towards the cell. The parameter set may include one or more parameters (e.g., one or more offsets, priorities) related to the cell reselection process. Alternatively, or in addition, the process towards the cell may comprise a handover process towards the cell. It should be understood that cell selection and cell reselection are typically performed by the first device 110, but the handover process may be triggered by the second device 120.

[0060] Exemplary parameters of the parameter set are described in detail below.

[0061] In some demonstrative embodiments, the first device 110 may receive 215 a first set of values ​​for the parameter set from the second device 120. Alternatively or additionally, the first device 110 may receive 225 a second set of values ​​for the parameter set from the second device 120. For example, if the first device 110 is a legacy device or if the cell is a legacy cell, the first set of values ​​is received without the second set of values. In another example, if the cell is an ED cell, at least the second set of values ​​is received by the first device 110.

[0062] Then, in some demonstrative embodiments, the first device 110 may determine whether a condition associated with extended duplex operation is met (230). By way of example, the condition may include that a second set of values ​​for a parameter set is received. Alternatively or additionally, the condition may include that the first device 110 supports extended duplex operation, or in other words, that the first device 110 is an ED-aware device. For example, if the first device 110 indicates support for extended duplex operation in the capability information message, it may be determined that the first device 110 supports extended duplex operation.

[0063] Alternatively or additionally, the condition may include the cell being known to the first device 110 to be capable of extended duplex operation. For example, if the second device 120 sends an indication to the first device 110 that the cell is capable of extended duplex operation, the cell may be determined to be known to the first device 110 to be capable of extended duplex operation.

[0064] It should be understood that the above examples of conditions are given for illustrative purposes without any limitation. Any suitable conditions associated with extended duplex operation may be implemented in exemplary embodiments of the present disclosure.

[0065] If the condition is not met, the first device 110 may apply a first set of values ​​to the process toward the cell. For example, if the first device 110 is a legacy device or if the cell is a legacy cell, the first set of values ​​may be applied to the process toward the cell.

[0066] If the condition is met, the first device 110 may apply at least the second set of values ​​to the process toward the cell (235). For example, if the first device 110 is an ED-aware device and the cell is an ED cell, at least the second set of values ​​may be applied to the process toward the cell. In some exemplary embodiments, the second set of values ​​may be used without the first set of values. In other words, the second set of values ​​replaces the first set of values. Alternatively, in some exemplary embodiments, the second set of values ​​may be used in combination with the first set of values. For example, if the parameter set includes an offset, the final offset for the ED cell is determined based on a first offset value in the first set and a second offset value in the second set. Such embodiments are described in detail below.

[0067] It should be understood that in some exemplary embodiments, the check of the condition at 230 may be omitted. For example, if the first device 110 can receive the second set of values, it may not check the condition. In another example, if the first device 110 is an ED-aware device, it may not need to check the condition. In such exemplary embodiments, the first device 110 may at least apply the received second set of values ​​to the process toward the cell.

[0068] An example interaction between the first device 110 and the second device 120 is described above with reference to Figure 2. Through the use of an additional set of parameter values, legacy devices and ED-aware devices may be efficiently controlled for ED cell selection, ED cell reselection, or ED cell handover.

[0069] Some exemplary parameters in the parameter set are described below.

[0070] In some exemplary embodiments, the parameter set may include an offset to a minimum required signal reception level of the received signal, also referred to as a "reception level offset." Alternatively or additionally, the parameter set may include an offset to a minimum required signal quality level of the received signal, also referred to as a "quality level offset." The reception level offset and the quality level offset may be configured per cell or per frequency.

[0071] A cell selection or cell reselection may be performed when a corresponding cell selection criterion S or cell reselection criterion S is met. Srxlev>0 and Squal>0(1) where: Srxlev=Q rxlevmeas -(Q rxlevmin +Q rxlevminoffset )-P compensation -Qoffset temp (2) Squal=Q qualmeas -(Q qualmin +Q qualminoffset )-Qoffset temp (3)

[0072] The receive level offset is the parameter "Q rxlevminoffset ” and the quality level offset is the parameter “Q qualminoffsetIn some exemplary embodiments, in the first set of values, the second device 120 may set a parameter “Q ” associated with the ED cell to prevent legacy devices from selecting the ED cell as a target cell. rxlevminoffset " and "Q qualminoffset " may be increased. In this way, the cell selection or cell reselection criteria may be difficult to meet for legacy devices, and legacy devices may not prioritize selecting or reselecting to ED cells.

[0073] Meanwhile, in the second set of values, the second device 120 may set a parameter “Q ” associated with the ED cell to facilitate the ED-aware device selecting or reselecting to the ED cell. rxlevminoffset " and "Q qualminoffset A second offset value for the parameter "Q" can be configured. rxlevminoffset " and "Q qualminoffset The second offset value for " is Q rxlevminoffsetED and Q qualminoffsetED Therefore, when an ED-aware device performs cell selection or cell reselection to an ED cell, "Srxlev" and "Squal" in equation (1) can be derived as follows: Srxlev=Q rxlevmeas -(Q rxlevmin +Q rxlevminoffsetED )-P compensation -Qoffset temp (4) Squal=Q qualmeas -(Q qualmin +Q qualminoffsetED )-Qoffset temp (5)

[0074] The first offset value for the received level offset is different (e.g., higher) than the second offset value for the received level offset. Similarly, the first offset value for the quality level offset is different (e.g., higher) than the second offset value for the quality level.

[0075] In some exemplary embodiments, the second offset value may be used instead of the first offset value to determine the criterion S. In some exemplary embodiments, both the second offset value and the first offset value may be used to determine the criterion S. For example, in the case of an ED cell, the ED-aware device may first determine an initial value of the criterion S by applying the first offset value in the first set, and add or subtract the second offset value to the initial value of the criterion S to obtain a final value of the criterion S.

[0076] In some exemplary embodiments, the second offset value may be ED cell-specific, in other words, each ED cell is configured with the second offset value. Alternatively, in some exemplary embodiments, the second offset value may be common to all ED cells. The second device 120 may configure a common offset value or a group of common offset values ​​for all ED cells. The second device 120 may transmit an indication of which cells are ED cells to the first device 110. Thus, the first device 110 may apply the common offset value or group of common offset values ​​to determine the criterion S for the ED cells.

[0077] The second offset value may be transmitted in any suitable signaling. For example, a second offset value related to a cell selection process may be transmitted in SIB1. A second offset value related to an intra-frequency cell reselection process may be transmitted in SIB3. An offset value related to an inter-frequency cell reselection process may be transmitted in SIB4. However, these are given as examples without limiting the scope of protection.

[0078] In some exemplary embodiments, the parameter set may be a minimum required signal reception level for the received signal, e.g., Q rxlevmin Alternatively or additionally, the parameter set may include a minimum required signal quality level for the received signal, such as Q qualminThe minimum required signal reception level and minimum required signal quality level may be configured per cell or per frequency.

[0079] Similar to the reception level offset and reception quality offset, in some exemplary embodiments, a first value of these levels in a first set may be greater than a second value of these levels in a second set to prevent legacy devices from determining the ED cell as a target cell and / or to facilitate ED-aware devices from determining the ED cell as a target cell.

[0080] In some exemplary embodiments, the parameter sets may include priorities for selecting a serving cell, i.e., priorities for cell selection or priorities for selection as a serving cell. For example, an ED cell may have a relatively low priority in a first set and / or an ED cell may have a relatively high priority in a second set.

[0081] Alternatively or additionally, in some exemplary embodiments, the parameter sets may include priorities for reselecting a target cell from a group of cells, or in other words, priorities for cell reselection. For example, in a first set, a parameter CellReselectionPriority indicating a priority of ED cells to be used by legacy devices may be set to a low value. Meanwhile, in a second set, a parameter CellReselectionPriority-ED indicating a priority of ED cells to be used by ED-aware devices may be set to a higher value. Thus, legacy devices are prevented from reselecting toward ED cells and / or ED-aware devices are facilitated from reselecting toward ED cells.

[0082] In such an exemplary embodiment, the second device 120 may configure a low priority for an ED frequency or cell, so that legacy devices will not camp on that frequency or cell unless there are other frequencies or cells to camp on. However, for ED-aware devices, the second device 120 may configure a different priority that allows for more prioritized camping on the ED frequency or cell.

[0083] As an example use case, after selecting or reselecting a cell on a frequency layer according to the priority value "CellReselectionPriority-ED-rXX" in the second set, the first device 110 may acquire target cell system information and find that the cell does not support ED operation. ED capability may be signaled by the cell in the system information. The first device 110 may be requested to perform cell selection or reselection again by applying offsets to the corresponding cell. These offsets (e.g., indicated by q-RxLevMinOffset-noEDCell-rXX and q-QualMinOffset-noEDCell-rXX) may be signaled along with "CellReselectionPriority-ED-rXX."

[0084] In some exemplary embodiments, the parameter set may include a first list of neighbor cells available for cell reselection. The first device 110 may use the cells in the first list during the cell reselection process. For example, the first list may be intraFreqAllowedCellList and / or interFreqAllowedCellList. The first set of values ​​may comprise a first version of the first list that may include legacy cells. The second set of values ​​may comprise a second version of the first list that may include ED cells.

[0085] Alternatively or additionally, the parameter set may include a second list of neighbor cells unavailable for cell reselection. The first device 110 does not use cells in the second list during the cell reselection process. For example, the second list may be intraFreqExcludedCellList and / or interFreqExcludedCellList. The first set of values ​​may comprise a first version of the second list that may include ED cells. The second set of values ​​may comprise a second version of the second list that may include legacy cells or may be empty.

[0086] In some exemplary embodiments, the parameter set may include a frequency-specific offset to the quality measure for reselecting a target cell from a group of cells that includes the cell. For example, this offset may be frequency where the first set of values ​​associated with the ED cell may include a first value of the frequency-specific offset, while the second set of values ​​associated with the ED cell may include a second value of the frequency-specific offset. The second value may be different from the first value.

[0087] Some parameters have been described above. However, it should be understood that these parameters are given as examples without limiting the scope of protection. Other parameters may also be possible. For example, the parameter set may include an offset for the level of the received signal (Rx level). In another example, the parameter set may include an offset for the quality level of the received signal (Rx quality).

[0088] The values ​​of the parameter sets may be transmitted in any suitable signaling. For example, an offset value to be used for cell selection may be transmitted in SIB1. An offset value used for intra-frequency cell reselection may be transmitted in SIB3, and an offset value used for inter-frequency cell reselection may be transmitted in SIB4. As another example, a priority value for cell or frequency reselection may be transmitted in an RRCRelease message, a priority value for intra-frequency cell reselection may be transmitted in SIB2, and a priority value to be used for inter-frequency cell reselection may be transmitted in SIB4. It should be understood that the above signaling is given by way of example without limiting the scope of protection. Any other suitable signaling may be possible.

[0089] In the above exemplary embodiment, the first set of values ​​is configured to make it more difficult for a legacy device to determine an ED cell as a target cell, and the second set of values ​​is configured to make it easier for an ED-aware device to determine an ED cell as a target cell. It should be understood that alternatives may be possible as long as these two sets of values ​​can distinguish the behavior of a legacy device and an ED-aware device. For example, the first set of values ​​may be configured to make it easier for a legacy device to determine a legacy cell as a target cell, while the second set of values ​​may be configured to make it more difficult for an ED-aware device to determine a legacy cell as a target cell. In such an example, the first device 110 may apply the second set of values ​​to the process toward the legacy cell. Thus, the conditions checked at 230 may include that the cell is known to be a legacy cell and that the first device 110 supports ED operation.

[0090] Some exemplary embodiments are directed to networks for mobile communications. In such networks, a subset of terminal devices (UEs) is prepared for the feature. Also, a subset of network devices (base stations) supports the feature. In some exemplary embodiments, the feature relates to enhanced duplex operation, such as SBFD (Sub-Band Non-Overlapping Full Duplex) or Flexible Duplex (Cross-Division Duplex) or Flexible TDD or Dynamic TDD (in some geographical regions, the TDD rhythm does not need to be the same for all cells on the same frequency or within the same operating band).

[0091] For at least a subset of cells, there are at least two different sets of values ​​for a parameter set related to, for example, a process toward the cell. For other cells, there may be only one set of values. The process toward the cell may refer to cell selection, cell reselection, and / or handover. Thus, in the exemplary embodiment, the parameters relate to cell selection, cell reselection, and / or handover. The network device signals these values. UEs not prepared for the feature (legacy UEs) apply the first set of values. UEs prepared for the feature (e.g., ED-aware UEs) apply the second set of values ​​for cells from the subset of cells and the first set of values ​​for other cells. (A set in this context includes at least one value.) In the case of cell selection, the set of values ​​refers to the cell signaling the values. In the case of cell reselection and / or handover, the set of one or more values ​​refers, at least in part, to one or more neighboring cells of the cell signaling the values. The signaling can be performed, for example, by transmitting in a SIB or by broadcasting a SIB.

[0092] The first set of values ​​is used by UEs that are not prepared for the feature. The first set of values ​​may be configured to increase the likelihood of selecting a cell that does not support the feature (a legacy cell) over the likelihood of selecting a cell that supports the feature (e.g., an ED cell) under comparable RX conditions. This configuration is intended for UEs that are not prepared for the feature. They preferably select a cell that does not support the feature.

[0093] The second set of values ​​may be configured to select a cell that supports the feature at least as likely as a cell that does not support the feature under comparable RX conditions. This configuration is targeted to UEs that are prepared for the feature. UEs that are not prepared for the feature may not be able to process the second set of values.

[0094] In the embodiment where the subset of cells consists of cells that support the feature: the first set of values ​​contains non-preferred values ​​for cells that support the feature, i.e., it is rather unlikely to select or reselect / handover to a cell that supports the feature if there are also suitable cells that do not support the feature that the UE can connect to. The second set of values ​​is for UEs that are prepared for the feature, so that these UEs apply normal (neutral) or rather preferred values ​​for cells that support the feature. This means that the second set of values ​​is applied to the combination of UEs prepared for the feature and cells that support the feature.

[0095] Example where a subset of cells consists of cells that do not support the feature: The first set of values ​​contains preferred values ​​for cells that do not support the feature, i.e., if there is a suitable cell that does not support the feature that the UE can connect to, it will rather select or reselect / handover to a cell that does not support the feature. The second set of values ​​is for UEs that are prepared for the feature, so that these UEs apply normal (neutral) or rather non-preferred values ​​to cells that do not support the feature. This means that the second set of values ​​is applied to the combination of UEs prepared for the feature and cells that do not support the feature.

[0096] The first set of values ​​may be signaled anyway, since legacy UEs require it. There are several ways to make UEs prepared for the feature apply the second set of values ​​for the cell. Examples include:

[0097] For a cell for which a UE prepared for the feature applies the second set of values, the second set of values ​​is transmitted, for example, in a system information block (SIB). A UE prepared for the feature checks whether the second set of values ​​is signaled for the cell. If so, the UE receives and / or applies at least the second set of values ​​for the cell. If at least the second set of values ​​is not signaled for the cell, the UE receives and / or applies the first set of values ​​for the cell.

[0098] In another example, the UE receives an indication that a cell supports a feature, or an indication that the cell does not support a feature, or an indication as to which set of values ​​to use for the cell. The second set of values ​​may be received separately. This is particularly efficient when the second set of values ​​is the same for a subset of cells. The second set of values ​​may be applied in combination with the first set of values.

[0099] For neighboring cells that support the feature or for neighboring cells that do not support the feature, the base station of the network signals at least two sets of values ​​(each set having at least one element, i.e., one value or parameter) that affect the UE's cell reselection and / or handover: at least one set for UEs that do not support the feature and another set for UEs that do support the feature.

[0100] The set of values ​​may refer to a cell or a frequency layer (this characteristic may be different for different sets).

[0101] One set of values ​​may be applied relative to another set of values, e.g., for neighboring cells that support a feature, a set of values ​​for UEs that support the feature may be applied relative to (particularly as an offset from) a set of values ​​for UEs that do not support the feature. The base station signals which neighboring cells support the feature or to which neighboring cells a set of values ​​for UEs supporting the feature applies.

[0102] Example: Legacy signaling of RX levels and / or RX quality metrics is configured to make it difficult for legacy UEs to reselect to ED cells. In addition to the cell-specific values ​​in the first set of values, an offset to apply to ED-aware UEs in all ED cells (or in all ED cells in the neighbor cell list) is signaled. This offset makes it easier for ED-aware UEs to select an ED cell. Because this offset is the same for all base stations in the entire neighbor cell list, there is no need to signal a separate set of values ​​for each and every neighbor ED cell; one common set of values ​​(especially offset values) for all ED cells is sufficient. This set of values ​​does not replace, but may complement, the set of values ​​for legacy UEs.

[0103] There are base stations that provide cells of the network for mobile communications and support features that are supported by a subset of UEs.

[0104] The base station signals at least two sets of values ​​(where each set has at least one element, e.g., one parameter) that influence the UE's cell selection, i.e., at least one set for UEs that do not support the feature and another set for UEs that support the feature, which can include both UL and DL simultaneously in TDD bands, especially SBFD.

[0105] For UEs that do not support this feature or that make an emergency call, or that meet both conditions, the base station allocates UL radio resources without simultaneous DL.

[0106] For UEs that do not support this feature or that make an emergency call, or that meet both conditions, the base station allocates DL radio resources without simultaneous UL.

[0107] At least two sets of values ​​result in stricter conditions for the ED cell to be selected as a serving cell for UEs that do not support the feature than for UEs that do support the feature.

[0108] Examples of more stringent conditions are: - The cell is effectively banned. - Only emergency calls are allowed. - the base station is part of a network having base stations that support the feature and base stations that do not support the feature, and a less favorable offset (making the selection of the cell as the serving cell less likely) is applied in cells of base stations that support the feature for RX level and / or RX quality related criteria (the offset is not considered to be 0 or a 0 dB offset) compared to cells that do not support the feature.

[0109] When a UE is commanded to perform a handover, the selection of a target cell depends on supporting characteristics of the UE and the candidate target cells.
