Description

Technical Field

[0001] Various example embodiments described herein relate generally to the field of telecommunications, and in particular, to methods, devices, apparatus, and computer-readable storage media for controlling a process for a cell with enhanced duplex operation. Background Art

[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). Allocating limited duration for uplink in TDD will result in reduced coverage, increased latency, and reduced capacity.

[0003] To address the above challenges, research on the evolution of duplex operation in NR has been started. Subband non-overlapping full duplex (SBFD) has been proposed as a scheme for enhanced duplex operation. In SBFD, simultaneous DL transmission and UL reception at the NRNodeB (also known as gNB) are allowed on different physical resource blocks (PRBs) within an unpaired wideband NR cell. This duplex scheme is also known as cross-division duplex (xDD) or flexible duplex (FDU). Summary of the invention

Enhanced duplex operation may include simultaneous reception and transmission by a network device in an unpaired frequency band. Examples of enhanced duplex operation may include, but are not limited to, SBFD, dynamic or flexible TDD. Hereinafter, the term "enhanced duplex operation" is used for illustrative purposes without any limitation to the scope of protection. The example embodiments described herein for enhanced duplex operation may be applied to any suitable type of duplex operation.

[0035] Figure 1 An example communication environment 100 is shown in which example embodiments of the present disclosure may be implemented. The communication environment 100 includes a first device 110-1 and a first device 110-2, collectively referred to as "first device" 110 or individually referred to as "first device" 110. The first device 110 may communicate with a second device 120. The service area of ​​the second device 120 is referred to as a cell. The second device 120 may serve one or more cells, such as cell 102. In some example embodiments, the first device 110 may include a terminal device, and the second device 120 may include a network device serving the terminal device.

[0036] In the following, for the purpose of illustration, some example embodiments are described in which the first device 110 operates as a terminal device and the second device 120 operates as a network device. However, in some example embodiments, the operations described in conjunction with the terminal device may be implemented at a network device or other device, and the operations described in conjunction with the network device may be implemented at a terminal device or other device.

[0037] In some example embodiments, if 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 referred to as a downlink (DL), and the link from the first device 110 to the second device 120 is referred to as an uplink (UL). In the DL, the second device 120 is a transmission (TX) device (or transmitter), and the first device 110 is a reception (RX) device (or receiver). In the UL, the first device 110 is a TX device (or transmitter), and the second device 120 is an RX device (or receiver).

[0038] The communication in the communication environment 100 can be implemented according to any appropriate communication protocol, including but not limited to communication protocols of the first generation (1G), the second generation (2G), the third generation (3G), the fourth generation (4G), the fifth generation (5G), the sixth generation (6G), etc., wireless local area network communication protocols such as the Institute of Electrical and Electronics Engineers (IEEE) 802.11, and / or any other protocol currently known or developed in the future. In addition, the communication can utilize any appropriate wireless communication 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 currently known or developed in the future.

[0039] Cell 102 has the capability of enhanced duplex operation, or in other words, cell 102 supports enhanced duplex operation. Hereinafter, a cell having enhanced duplex operation capability or having enhanced duplex operation capability may also be referred to as an ED cell. For example, enhanced duplex operation may include SBFD operation, and accordingly cell 102 is an SBFD cell. It should be understood that SBFD operation is an example of enhanced duplex operation. In an example embodiment of the present disclosure, enhanced duplex operation may include any suitable type of duplex operation in addition to conventional TDD operation and FDD operation. For another example, enhanced duplex operation may include dynamic TDD operation.

[0040] In some example embodiments, environment 100 may include a cell 103 that does not have enhanced duplex operation capability, or in other words, the cell 103 cannot support enhanced duplex operation. For example, the cell 103 may not have the capability of SBFD operation. Hereinafter, a cell that does not have enhanced duplex operation capability may also be referred to as a legacy cell. In other words, ED cells and legacy cells may coexist in environment 100. However, this is an example. Alternatively, in some example embodiments, all cells may support enhanced duplex operation.

[0041] In some example embodiments, environment 100 may include a cell 104 served by another device than second device 120. Cell 104 may be a neighboring cell.

[0042] The first device 110-1 supports enhanced duplex operation, which may mean that the first device 110-1 knows that the second device (e.g., a network device) is capable of enhanced 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 does not support enhanced duplex operation and is therefore also referred to as a legacy device. In one example, enhanced duplex operation may include SBFD operation. Therefore, the first device 110-1 may be a SBFD-aware device and the first device 110-2 may be a legacy device.

[0043] It should be understood that the communication environment 100 is presented for illustrative purposes without accompanying any limitation on the scope of protection. The communication environment 100 may include any suitable number of devices and cells configured to implement the example embodiments of the present disclosure.

[0044] Take SBFD as an example of enhanced duplex operation. SBFD cells are expected to coexist with traditional cells, for example, from the perspective of supporting only co-channels (i.e., cells deployed on the same carrier frequency, such as belonging to the same operator) and adjacent channels (i.e., cells deployed on adjacent carriers, such as belonging to different operators), SBFD cells can coexist with other cells that only support traditional TDD operations. In addition, existing UEs that cannot be upgraded to support SBFD-specific functions can also be served on SBFD cells. It is expected that these UEs will not experience significant performance degradation, such as compared to the performance in traditional TDD cells. In other words, it is necessary to ensure the backward compatibility of SBFD cells.

[0045] On the other hand, during the cell selection or cell reselection process, the UE scans and measures signals on one or more radio frequencies to select a suitable serving cell and reside therein and / or decide whether to reselect from its current serving cell to another cell as its new serving cell. For example, the UE can measure the signal from the cell by measuring the reference signal received power (RSRP) and / or the reference signal received quality (RSRQ). One or more signal parameters of the signal received from the cell can be measured at the UE, and the cell selection (or reselection) value of the cell can be determined based on such signal parameters and one or more offsets and / or reselection priorities configured by the network. If the measured signal meets a predetermined criterion, the UE can select and / or reselect to the corresponding cell. The selection and / or reselection criteria can be adjusted based on the UE capabilities and whether the cell serves a specific application.

[0046] The absolute priority of different frequencies can be provided to the UE in system information or radio resource control (RRC) messages, such as the RRCRelease message. The UE shall perform cell reselection evaluation based on the priority of the frequencies given in the system information.

[0047] The SBFD cell may perform downlink transmission (DL Tx) and uplink reception (ULRx) simultaneously on non-overlapping PRBs while the UE is still operating in half-duplex (HD) mode. When the SBFD cell is serving both legacy UEs and SBFD-aware UEs, in order to simplify gNB implementation and / or limit the impact on the performance of legacy UEs, the SBFD cell may prefer to schedule legacy UEs only in downlink-only and uplink-only timeslots, while SBFD-aware UEs may also be scheduled during SBFD timeslots.

[0048] Therefore, a SBFD cell may be in a situation where granting access to legacy UEs may result in the need to reconfigure one or more SBFD timeslots as TDD (DL) timeslots. However, the gNB may want to operate with a given number of timeslots configured as SBFD timeslots to guarantee minimum uplink capacity and / or coverage. Furthermore, it may happen that the TDD UL resources of a cell are close to fully utilized, while the SBFD UL resources of the cell are still partially unused.

[0049] In any of the above situations, the SBFD cell may want to block access from legacy devices but not from SBFD-aware UEs. In other words, after the introduction of SBFD, 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 the behavior of legacy UEs from the behavior of SBFD-aware UEs with respect to procedures toward a SBFD cell, such as cell selection or cell reselection toward a SBFD cell.

[0050] In one solution, it is proposed to provide an indication of the duplex operation mode of a cell to the SBFD-aware UE to facilitate the SBFD-aware UE to select a SBFD cell. However, this solution cannot distinguish between the behavior of a conventional UE and the behavior of a SBFD-aware UE. Similar problems may occur for other types of enhanced duplex operation, such as dynamic TDD.

[0051] According to some example embodiments of the present disclosure, a solution for controlling a process for a cell with enhanced duplex operation is provided. In the solution, two different sets of values ​​are configured for a parameter set associated with a cell. An ED-aware device may apply one set of values ​​to a process toward a cell. A conventional device may apply another set of values ​​to a process toward a cell.

[0052] In an example embodiment of the present disclosure, ED-aware devices and legacy devices apply different sets of parameter values ​​to the process toward an ED cell. In this way, the behavior of legacy devices and ED-aware device behavior regarding the process toward an ED cell can be distinguished. For example, by controlling the values ​​of the two sets, legacy devices are prevented from determining an ED cell as a target cell, while ED-aware devices are still allowed to camp on or access an ED cell.

[0053] Hereinafter, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0054] Figure 2 A signaling diagram 200 for controlling a process toward a cell according to some example embodiments of the present disclosure is shown. Figure 2 As shown, the signaling diagram 200 involves a first device 110 and a second device 120. For discussion purposes, reference is made to Figure 1 To describe the signaling diagram 200. Figure 2 One first device 110 is shown in FIG. 1 , and it should be understood that there may be multiple first devices that perform similar operations as described below with respect to the first device 110 .

[0055] In some example embodiments, second device 120 may determine 205 whether a cell has enhanced duplex operation capability. For example, in a hybrid deployment scenario where a subset of cells on a frequency layer have SBFD capability, second device 120 may determine 205 whether a particular cell is an ED cell. For another example, for each cell in a group of cells (e.g., a group of neighboring cells), second device 120 may determine 205 whether the cell is an ED cell.

[0056] It should be understood that the cell may be a cell served by the second device 120, for example Figure 1 Alternatively or additionally, the cell may be a cell served by another device, such as Figure 1The cell 104 is shown in FIG. In this case, the cell may be a neighboring cell.

[0057] If the second device 120 determines that the cell does not have the capability of enhanced duplex operation, the second device 120 may transmit 210 a value for a first set of parameter sets to the first device 110. The parameter set is associated with a procedure toward the cell. For example, for a cell 103 that is not an ED cell, the second device 120 may transmit 210 a value for a first set of parameter sets associated with a procedure toward the cell 103 to the first device 110.

[0058] If the second device 120 determines that the cell has enhanced duplex operation capability, the second device 120 may transmit 220 at least a value for a second set of parameter sets to the first device 110. For example, for the cell 102 being 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 associated with a procedure toward the cell 120. It should be understood that the second set of values ​​may be configured to control an ED-aware device procedure toward a cell that has enhanced duplex operation capability.

[0059] In some example embodiments, only the second set of values ​​may be transmitted without transmitting the first set of values. For example, if the second device 120 knows that the first device 110 is an ED-aware device, the second device 120 may transmit the second set of values ​​without transmitting the first set of values.

[0060] Alternatively, in some example embodiments, second device 120 may transmit the value of the first set and the value of the second set to first device 110. For example, if second device 120 does not know whether first device 110 supports enhanced duplex operation, or if the value of the first set and the value of the second set are broadcast to a plurality of first devices including devices supporting ED operation and devices not supporting ED operation, second device 120 may transmit the value of the first set and the value of the second set.

[0061] The values ​​of the first set and / or the values ​​of the second set may be transmitted in any suitable signaling, for example, broadcast in a system information block (SIB), or transmitted in a dedicated signaling (such as an RRC message). If both the values ​​of the first set and the values ​​of the second set are transmitted to the first device 110, they may be transmitted separately or, for example, transmitted together in the same signaling.

[0062] In some example embodiments, action 205 may be omitted, and the second device 120 may transmit to the first device 110 the value of at least one of the first set of values ​​and the second set of values ​​of the parameter set. For example, for a cell having enhanced duplex operation capability, the second device 120 may transmit to the first device 110 at least the value of the second set, and for a cell not having this capability, the second device 120 may transmit to the first device 110 the value of the first set. For another example, in a deployment scenario where all cells have SBFD capability, determination of the capabilities of the cells may be unnecessary. In another example, for the purpose of cell selection, for a cell of the second device 120 having enhanced duplex operation capability, the second device 120 may transmit at least the value of the second set without determining its capabilities. This is because the second device 120 knows its own cell capabilities a priori.

[0063] In some example embodiments, the values ​​of the second set may result in a different likelihood of determining a cell as a target cell compared to the values ​​of the first set. In this manner, the behavior of ED-aware devices and legacy devices may be differentiated. Further, in some example embodiments, the values ​​of the second set may result in a higher likelihood of determining a cell as a target cell compared to the values ​​of the first set. In this manner, ED-aware devices may be facilitated to camp on or access an ED cell, and / or legacy devices may be prevented or blocked from camping on or accessing an ED cell.

[0064] In some example embodiments, a parameter set associated with a process toward a cell may include one or more parameters specific to the cell. In some example embodiments, the parameter set may include parameters for a group of cells including the cell. For example, the parameter set may include a priority for reselecting a target cell from the group of cells including the cell.

[0065] One or more parameters included in the parameter set may depend on the process for the cell. In some example embodiments, the process for the cell may include a cell selection process towards the cell. The parameter set may include one or more parameters associated with the cell selection process (e.g., one or more offsets). Alternatively or additionally, the process towards the cell may include a cell reselection process towards the cell. The parameter set may include one or more parameters associated with the cell reselection process (e.g., one or more offsets, priorities). Alternatively or additionally, the process towards the cell may include a handover process towards the cell. It should be understood that cell selection and cell reselection are typically performed by the first device 110, while the handover process may be triggered by the second device 120.

[0066] Example parameters of the parameter sets are described in detail below.

[0067] In some example embodiments, first device 110 may receive 215 values ​​for a first set of parameter sets from second device 120. Alternatively or additionally, first device 110 may receive 225 values ​​for a second set of parameter sets from second device 120. For example, if first device 110 is a legacy device or if the cell is a legacy cell, the values ​​of the first set are received without the values ​​of the second set. For another example, if the cell is an ED cell, at least the values ​​of the second set are received by first device 110.

[0068] Then, in some example embodiments, the first device 110 may determine 230 whether a condition associated with enhanced duplex operation is satisfied. As an example, the condition may include a received value for the second set of parameter sets. Alternatively or additionally, the condition may include that the first device 110 supports enhanced 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 enhanced duplex operation in the capability information message, it may be determined that the first device 110 supports enhanced duplex operation.

[0069] Alternatively or additionally, the condition may include that the cell is known by the first device 110 to have the capability of enhanced duplex operation. For example, if the second device 120 transmits an indication to the first device 110 that the cell is capable of enhanced duplex operation, it may be determined that the cell is known by the first device 110 to have the capability of enhanced duplex operation.

[0070] It should be understood that the above examples of conditions are given for illustrative purposes without any limitation. In example embodiments of the present disclosure, any suitable conditions associated with enhanced duplex operation may be implemented.

[0071] If the condition is not met, the first device 110 may apply the first set of values ​​to the procedure towards 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 procedure towards the cell.

[0072] If the condition is met, the first device 110 may apply 235 at least the value of the second set to the process toward the cell. For example, if the first device 110 is an ED-aware device and the cell is an ED cell, at least the value of the second set may be applied to the process toward the cell. In some example embodiments, the value of the second set may be used without the value of the first set. In other words, the value of the second set replaces the value of the first set. Alternatively, in some example embodiments, the value of the second set may be used in combination with the value of the first set. For example, if the parameter set includes an offset, the final offset for the ED cell is determined based on the first offset value in the first group and the second offset value in the second group. Such example embodiments will be described in detail below.

[0073] It should be understood that in some example embodiments, the check of the condition at 230 may be omitted. For example, if the first device 110 can receive the value of the second set, it may not check the condition. For another example, if the first device 110 is an ED-aware device, it may not need to check the condition. In such an example embodiment, the first device 110 may at least apply the received value of the second set to the process towards the cell.

[0074] Reference above Figure 2 An example interaction between the first device 110 and the second device 120 is described. By using values ​​of additional parameter sets, legacy devices and ED-aware devices may be efficiently controlled for ED cell selection, ED cell reselection, or ED cell switching.

[0075] Some example parameters in the parameter set are now described.

[0076] In some example embodiments, the parameter set may include an offset to a minimum required signal reception level for received signals, 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 for received signals, also referred to as a "quality level offset". The received level offset and quality level offset may be configurable per cell or per frequency.

[0077] When the corresponding cell selection criterion S or cell reselection criterion S is met, cell selection or cell reselection can be performed: Srxlev>0 and Squal>0 (1) in: Srxlev=Q rxlevmeas –(Q rxlevmin +Q rxlevminoffset )–P compensation -Qoffset temp (2) Squal=Q qualmeas -(Q qualmin +Q qualminoffset )-Qoffset temp (3)

[0078] The receive level offset can be the parameter “Q rxlevminoffset ”, and the quality level offset can be the parameter “Q qualminoffset In some example embodiments, in the value of the first set, the second device 120 may increase the parameter "Q rxlevminoffset ” and “ Q. qualminoffset" to prevent legacy devices from selecting the ED cell as the target cell. In this way, the cell selection or cell reselection criteria are made difficult for legacy devices to meet, and the legacy devices will be de-prioritized to select or reselect towards the ED cell.

[0079] Meanwhile, in the value of the second set, the second device 120 may be a parameter “Q rxlevminoffset ” and “ Q. qualminoffset " configures a second offset value to facilitate the ED sensing device to select an ED cell or reselect toward an ED cell. For parameter "Q rxlevminoffset ” and “ Q. qualminoffset The second offset value can be determined by Q rxlevminoffsetED andQ qualminoffsetED Represents, accordingly, when the ED aware device performs cell selection or cell reselection toward an ED cell, “Srxlev” and “Squal” in equation (1) can be derived as: Srxlev=Q rxlevmeas –(Q rxlevmin +Q qualminoffsetED )–P compensation -Qoffset temp (4) Squal=Q qualmeas –(Q qualmin +Q qualminoffsetED )-Qoffset temp (5)

[0080] The first offset value for the received horizontal offset is different from (eg, higher than) the second offset value for the received horizontal offset. Similarly, the first offset value for the quality level offset is different from (eg, higher than) the second offset value for the quality level.

[0081] In some example embodiments, the second offset value may be used to determine the criterion S instead of the first offset value. In some example embodiments, both the second offset value and the first offset value may be used to determine the criterion S. For example, for an ED cell, the ED sensing device may first determine an initial value of the criterion S by applying a first offset value in the first set, and add or subtract the second offset value from the initial value of the criterion S to obtain a final value of the criterion S.

[0082] In some example embodiments, the second offset value may be ED cell specific, or in other words, each ED cell is configured with a second offset value. Alternatively, in some example embodiments, the second offset value may be common to all ED cells. The second device 120 may configure a common offset value or a set of common offset values ​​for all ED cells. The second device 120 may transmit an indication of which cell is an ED cell to the first device 110. Thus, the first device 110 may apply the common offset value or a set of common offset values ​​to determine the standard S for the ED cell.

[0083] The second offset value may be transmitted in any suitable signaling. For example, the second offset value associated with the cell selection process may be transmitted in SIB1. The second offset value associated with the intra-frequency cell reselection process may be transmitted in SIB3. The offset value associated with the inter-frequency cell reselection process may be transmitted in SIB4. However, these are given as examples without limiting the scope of protection.

[0084] In some example embodiments, the parameter set may include a minimum required signal reception level for receiving a signal, for example, Q as shown in equation (2): rxlevmin Alternatively or additionally, the parameter set may include a minimum required signal quality level for the received signal, such as Q shown in equation (3) qualmin The minimum required signal reception level and the minimum required signal quality level can be configured per cell or per frequency.

[0085] Similar to the reception level offset and the reception quality offset, in some example embodiments, the first values ​​of these levels in the first group may be greater than the second values ​​of these levels in the second group to prevent legacy devices from determining the ED cell as a target cell and / or to facilitate ED-aware devices to determine the ED cell as a target cell.

[0086] In some example embodiments, the parameter set may include a priority for selecting a serving cell, or in other words, a priority for cell selection or a priority for selecting a cell as a serving cell. For example, an ED cell may have a relatively low priority in the first set, and / or an ED cell may have a relatively high priority in the second set.

[0087] Alternatively or additionally, in some example embodiments, the parameter set may include a priority for reselecting a target cell from a set of cells, or in other words, a priority for cell reselection. For example, in a first set, a parameter CellReselectionPriority representing the priority of an ED cell to be used by a legacy device may be set to a low value. Meanwhile, in a second set, a parameter CellReselectionPriority-ED representing the priority of an ED cell to be used by an ED-aware device may be set to a higher value. Thus, legacy devices are prevented from reselecting toward ED cells and / or ED-aware devices are facilitated to reselect toward ED cells.

[0088] In such an example embodiment, the second device 120 may configure a low priority for an ED frequency or cell, and thus a legacy device will not camp on that frequency or cell unless there are no other frequencies or cells to camp on. However, for ED-aware devices, the second device 120 may configure a different priority, which would allow for a higher priority to camp on an ED frequency or cell.

[0089] As an example use case, after selecting or reselecting a cell on the frequency layer according to the priority value "CellReselectionPriority-ED-rXX" in the second set, the first device 110 can obtain the target cell system information and find that the cell does not support ED operation. ED capabilities can be signaled by the cell in the system information. The first device 110 may be required to perform cell selection or reselection again by applying offsets to the corresponding cell. These offsets (for example, represented by q-RxLevMinOffset-noEDCell-rXX and q-QualMinOffset-noEDCell-rXX) can be signaled together with "CellReselectionPriority-ED-rXX".

[0090] In some example embodiments, the parameter set may include a first list of neighboring cells that may be used for cell reselection. The first device 110 may use cells in the first list during the cell reselection process. For example, the first list may be intraFreqAllowedCellList and / or interFreqAllowedCellList. The value of the first set may include a first version of the first list, which may include legacy cells. The value of the second set may include a second version of the first list, which may include ED cells.

[0091] Alternatively or additionally, the parameter set may include a second list of neighboring cells that are not available for cell reselection. During the cell reselection process, the first device 110 will not use the cells in the second list. For example, the second list may be intraFreqExcludedCellList and / or interFreqExcludedCellList. The value of the first set may include a first version of the second list, which may include ED cells. The value of the second set may include a second version of the second list, which may include legacy cells or may be empty.

[0092] In some example embodiments, the parameter set may include a frequency-specific offset to the quality measurement used to reselect a target cell from a group of cells including the target cell. For example, the offset may be Qoffset frequency , which is a frequency specific offset for equal priority frequencies. The first set of values ​​associated with the ED cell may include a first value for the frequency specific offset, and the second set of values ​​associated with the ED cell may include a second value for the frequency specific offset. The second value may be different from the first value.

[0093] Some parameters are described above. However, it should be understood that these parameters are given as examples without any limitation on the scope of protection. Other parameters are also possible. For example, a parameter set may include an offset to the level of the received signal (Rx level). For another example, a parameter set may include an offset to the quality level of the received signal (Rx quality).

[0094] The value of the parameter set 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 to be used for intra-frequency cell reselection may be transmitted in SIB3, and an offset value to be 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 for inter-frequency cell reselection may be transmitted in SIB4. It should be understood that the above signaling is given as an example without any limitation on the scope of protection. Any other suitable signaling is also possible.

[0095] In the above example embodiment, the values ​​of the first set are configured to make it more difficult for a legacy device to determine an ED cell as a target cell, while the values ​​of the second set are 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 the values ​​of the two sets can distinguish the behavior of a legacy device and an ED-aware device. For example, the values ​​of the first set may be configured to make it easier for a legacy device to determine a legacy cell as a target cell, while the values ​​of the second set 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 values ​​of the second set to the process toward a legacy cell. Therefore, 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.

[0096] Some example embodiments are intended for networks for mobile communications. In such a network, a subset of terminal devices (UE) is prepared for this feature. A subset of network equipment (base stations) also supports this feature. In some example embodiments, this feature involves enhanced duplex operation, such as SBFD (sub-band non-overlapping full duplex) or flexible duplex (cross-division duplex) or flexible TDD or dynamic TDD (wherein, in some geographic areas, the TDD rhythm does not need to be the same for all cells on the same frequency or in the same operating band).

[0097] For at least a subset of cells, there are at least 2 different sets of values ​​for parameter sets associated with, for example, a process toward the cell. In other cells, there may be only one set of values. The process toward the cell may refer to cell selection, cell reselection and / or switching. Therefore, in an example embodiment, the parameters relate to cell selection, cell reselection and / or switching. The network device signals these values. UEs that are not ready for this feature (legacy UEs) apply the values ​​of the first set. UEs that are ready for this feature (e.g., ED-aware UEs) apply the values ​​of the second set to cells from a subset of cells, and they apply the values ​​of the first set to other cells. (A set in this context contains at least 1 value.) For the case of cell selection, the values ​​of one or more sets refer to the cell that signals the value. For the case of cell reselection and / or switching, the values ​​of one or more sets refer, at least in part, to one or more neighboring cells of the cell that signal the value. Signaling can be performed, for example, by transmission in a SIB or by broadcasting.

[0098] The values ​​of the first set are used by UEs that are not prepared for the feature. The values ​​of the first set can be configured so that under comparable RX conditions, it is more likely to select a cell that does not support the feature (legacy cell) than a cell that supports the feature (e.g., ED cell). This configuration is for UEs that are not prepared for the feature. They should preferably select a cell that does not support the feature.

[0099] The values ​​of the second set may be configured to make selection of a unit supporting the feature at least as likely as selection of a unit not supporting the feature under comparable RX conditions. The configuration is for UEs prepared for the feature. UEs not prepared for the feature may not be able to handle the values ​​of the second set.

[0100] Example where the cell subset consists of cells supporting the feature: The first set of values ​​contains unfavorable values ​​for cells supporting the feature, i.e., selection of a cell supporting the feature or reselection / handover to a cell supporting the feature is rather unlikely if there are also suitable cells that do not support the feature to which the UE can connect. The second set of values ​​is for UEs that are prepared for the feature. This causes these UEs to apply normal (neutral) or rather favorable values ​​for cells supporting the feature. This means that the second set of values ​​applies to combinations of UEs prepared for the feature and cells supporting the feature.

[0101] In the example where the subset of cells consists of cells that do not support the feature: The values ​​of the first set contain favorable values ​​for cells that do not support the feature, i.e., if there is a suitable cell that does not support the feature and to which the UE can connect, the values ​​of this set make it more likely to select or reselect / switch to a cell that does not support the feature. The values ​​of the second set are for UEs that are prepared for the feature. This makes these UEs apply normal (neutral) or quite unfavorable values ​​for cells that do not support the feature. This means that the values ​​of the second set are applicable to the combination of UEs that are prepared for the feature and cells that do not support the feature.

[0102] The first set of values ​​can still be signaled anyway, since legacy UEs require it. There are multiple ways to have a feature-ready UE apply the second set of values ​​to a cell. Examples include:

[0103] For cells that require UEs prepared for the feature to apply a second set of values, the second set of values ​​are transmitted, for example, in a system information block (SIB). The UE prepared for the feature checks whether the second set of values ​​for the cell is signaled. If so, the UE receives and / or applies at least the second set of values ​​for the cell. At least if no second set of values ​​are signaled for the cell, the UE receives and / or applies the first set of values ​​for the cell.

[0104] In another example, the UE receives an indication that the cell supports a feature or an indication that the cell does not support a feature or an indication of which set of values ​​to use for the cell. The values ​​of the second set may be received separately. This is particularly effective if the values ​​of the second set are the same for a subset of cells. The values ​​of the second set may be applied in combination with the values ​​of the first set.

[0105] For neighboring cells that support the feature or for neighboring cells that do not support the feature, the network's base station signals at least two sets of values ​​(where each set has at least one element, i.e., a value or parameter) that affect the UE's cell reselection and / or switching - at least one set for UEs that do not support the feature and another set for UEs that support the feature.

[0106] The value of a set can refer to a cell or a frequency layer. (This attribute can be different for different sets.)

[0107] The values ​​of one set may be applied relative to the values ​​of another set. For example, for neighboring cells that support the feature, the values ​​of the set of UEs that support the feature may be applied relative to (particularly as an offset) the values ​​of the set of UEs that do not support the feature.

[0108] The base station signaling indicates which neighboring cells support the feature or which neighboring cells the value of a set of UEs supporting the feature applies to.

[0109] Example: Legacy signaling of RX levels and / or RX quality criteria is configured to make it difficult for legacy UEs to reselect to ED cells. In all ED cells (or all ED cells in a list of neighboring cells), in addition to the cell-specific values ​​in the first set of values, an applicable offset is signaled to the ED-aware UEs. The offset makes it easier for the ED-aware UE to select an ED cell. Since the offset is the same for all base stations in the entire list of neighboring cells, there is no need to signal a separate set of values ​​for each neighboring ED cell - one common set of values ​​for all ED cells (in particular the offset value) is sufficient. The values ​​of this set may not replace, but supplement the values ​​of the set for legacy UEs.

[0110] There is a base station serving a cell of the network for mobile communications and supporting features supported by a subset of UEs.

[0111] Base station signaling indicates at least two sets of values ​​(where each set has at least one element, such as a parameter) that affect cell selection of the UE - at least one set for UEs that do not support the feature and another set for UEs that support the feature. The feature may involve simultaneous UL and DL in a TDD band, in particular SBFD.

[0112] For a UE that does not support this feature or makes an emergency call or satisfies both conditions, the base station allocates radio resources for only UL without including DL.

[0113] For a UE that does not support this feature or makes an emergency call or satisfies both conditions, the base station allocates radio resources of only DL without including UL.

[0114] Two fewer sets of values ​​result in stricter conditions for the ED cell to be selected as the serving cell for UEs that do not support the feature than for UEs that support the feature.

[0115] An example of a stricter condition is: One neighborhood was 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. A less favorable offset (making the cell less likely to be selected as a serving cell) is applied to RX level and / or RX quality related criteria in cells of the base station that supports the feature compared to cells that do not support the feature (where no offset may be considered an offset of 0 or 0 dB).

[0116] When a UE is commanded to perform a handover, the selection of the target cell depends on the support of features by the UE and the target cell candidates.
