Description

[0001] METHODS AND RELATED WIRELESS DEVICE AND NETWORK NODE FOR IMPROVING

[0002] USAGE OF BAND RESOURCES

[0003] The present disclosure pertains to the field of wireless communications. The present disclosure relates to methods for improving usage of band resources, a related wireless device, and a related network node.

[0004] BACKGROUND

[0005] Over time, wireless communication systems have become increasingly ubiquitous and fundamental to the operations of many devices and systems. Improvement in the efficiency and accuracy of these wireless communication systems has improved in parallel to the growth of this field. As a result of this growth, more and more new features and use cases have been introduced in New Radio (NR), and consequently the co-existence between different services and users has become increasingly important.

[0006] To efficiently apply NR technology taking into account this co-existence, signal filtering performance of wireless devices (e.g., user equipment) is an important factor. Effective filters at wireless devices are critical for achieving high spectral efficiency in contemporary systems, such as in systems relating to sub-band full duplexes, SBFD, and low-power wake-up signals, LP- WUS.

[0007] However, effective (such as high performing) signal filters are expensive. Low-end wireless devices may have worse filter characteristics than high-end ones and thus can be a limiting factor in the usage of SBFD, the deployment of LP-WUS, and / or the overall performance, of a wireless communication system. For example, a network may not know an exact filtering performance and / or range of filtering performance of wireless devices in a wireless communication system. The network may only know the worst filtering performance of the system, e.g., filtering performance of the lowest-end wireless device. The network may thereby apply wide resource for guard bands to all the other wireless devices in the system, unnecessarily reducing its overall performance.

[0008] SUMMARY

[0009] Accordingly, there is a need for devices and methods, e.g., for improving usage of band resources, such as sub-band resources, which may mitigate, alleviate, or address the shortcomings existing and may provide improved efficiency, reliability, and robustness of communications in a wireless network. A method, performed by a network node is disclosed. The method comprises indicating, to a wireless device, a triggering indication. The method comprises receiving, from the wireless device, performance information indicative of a first filtering performance of the wireless device. The method comprises transmitting, to the wireless device, a resource block configuration after receiving the performance information.

[0010] A network node is disclosed. The network node comprises memory circuitry, processor circuitry, and a wireless interface. The network node is configured to perform any of the methods disclosed herein.

[0011] It is an advantage of the present disclosure that the disclosed network node and related method may enable an improved usage of frequency resources, such as sub-band resources, e.g., in its resource scheduling.

[0012] Further, the disclosed network node and related method enable the network, such as the network nodes, to perform transmissions based on accurate wireless device (WD) filtering performance, such as actual filtering performance of the wireless device. This may enable the network may adopt a less conservative resource configuration scheme, such as a resource allocation scheme. For example, the network may adjust the resource configuration scheme with smaller guard resource blocks and / or a smaller guard band, e.g., based on the actual wireless device filtering performance. In other words, the network may adjust the resource configuration scheme such that excessively large guard bands are avoided. The disclosed network node and related method may enable an improved spectrum usage in a wireless communication network.

[0013] Furthermore, the disclosed network node and related method may enable the network, such as the network node, to update the resource configuration scheme dynamically per wireless device, such as based on the dynamically changing filtering performance of one or more of, such as each of, the wireless devices. This allows for transmissions of the wireless communication system to be received by the wireless device with an improved accuracy, reliability, and / or robustness, e.g., despite variations in filtering performance. For example, the position of the bandwidth part (BWP), and the actual radiofrequency (RF) bandwidth (BW), the wireless device filtering performance may vary from time to time, such as dynamically, e.g., based on the number of resource blocks configured for the wireless device to receive and transmit. A method, performed by a wireless device is disclosed. The method comprises receiving from a network node, a triggering indication. The method comprises transmitting, to the network node and based on the triggering indication, performance information indicative of a first filtering performance of the wireless device. The method comprises receiving, from the network node, a resource block configuration for the wireless device.

[0014] A wireless device is disclosed. The wireless device comprises memory circuitry, processor circuitry, and a wireless interface. The wireless device is configured to perform any of the methods disclosed herein.

[0015] It is an advantage of the present disclosure that the disclosed wireless device and related method may enable an improved usage of frequency resources, such as sub-band resources, e.g., in its resource scheduling.

[0016] Further, the disclosed wireless device and related method enable the network, such as the network nodes, to perform transmissions based on accurate wireless device filtering performance, such as actual filtering performance of the wireless device. This may enable the network may adopt a less conservative resource configuration scheme, such as a resource allocation scheme. For example, the network may adjust the resource configuration scheme with smaller guard resource blocks and / or a smaller guard band, e.g., based on the actual wireless device filtering performance. In other words, the network may adjust the resource configuration scheme such that excessively large guard bands are avoided. The disclosed wireless device and related method may enable an improved spectrum usage in a wireless communication network.

[0017] Furthermore, the disclosed wireless device and related method may enable the network to update the resource configuration scheme dynamically per wireless device, such as based on the dynamically changing filtering performance of one or more of, such as each, wireless device. This allows for the transmissions of the wireless communication system to be received with an improved accuracy, reliability, and / or robustness, e.g., despite variations in filtering performance. For example, the position of the bandwidth part (BWP), and the actual RF BW, the wireless device filtering performance may vary from time to time, such as dynamically, e.g., based on the number of resource blocks configured for the wireless device to receive and transmit.

[0027] DETAILED DESCRIPTION

[0028] Various examples and details are described hereinafter, with reference to the figures when relevant. It should be noted that the figures may or may not be drawn to scale and that elements of similar structures or functions are represented by like reference numerals throughout the figures. It should also be noted that the figures are only intended to facilitate the description of the examples. They are not intended as an exhaustive description of the disclosure or as a limitation on the scope of the disclosure. In addition, an illustrated example needs not have all the aspects or advantages shown. An aspect or an advantage described in conjunction with a particular example is not necessarily limited to that example and can be practiced in any other examples even if not so illustrated, or if not so explicitly described.

[0029] A connected mode may be referred to an operation mode wherein a data transmission can be communicated e.g. between the wireless device and a network node or between the wireless device and another wireless device. A connected mode may be referred to an operation state wherein a radio transmitter and / or a radio receiver is activated for such communication. A connected mode may be referred to an operation state wherein the wireless device is synchronized time-wise and / or frequency-wise e.g. by a determined timing advance parameter for the communication. In certain communication systems, a connected mode may be referred to a radio resource control (RRC) state. In various examples, an active state may be a RRC connected state and / or an RRC active state. However, a connected mode may be an active period within another RRC state.

[0030] The dormant mode is a mode where the wireless device has no active connection with the network node. A dormant mode may be seen as an inactive mode of the wireless device. A dormant mode may be seen as a mode where the wireless device is unsynchronized with a timing of a network. In one or many examples the wireless device may in a dormant mode not have a valid timing advance information with respect to the network. A dormant mode may be seen as a mode where the wireless device is unable to receive dedicated signaling. A dormant mode may be seen as a mode where closed loop power control is inactivated or suspended. Dormant mode may comprise RRC idle mode, RRC suspend and / or RRC inactive mode. For example, the wireless device may be in dormant mode when the connection with the network node has been released and / or suspended.

[0031] The figures are schematic and simplified for clarity, and they merely show details which aid understanding the disclosure, while other details have been left out. Throughout, the same reference numerals are used for identical or corresponding parts.

[0032] Fig. 1 is a diagram illustrating an example wireless communication system 1 comprising an example network node 400 and an example wireless device (WD) 300 according to this disclosure.

[0033] As discussed in detail herein, the present disclosure relates to a wireless communication system 1 comprising a cellular system, for example, a 3GPP wireless communication system. The wireless communication system 1 comprises a wireless device 300 and / or a network node 400.

[0034] A network node disclosed herein refers to a radio access network (RAN) node operating in the radio access network (e.g., a network utilising Integrate Access Backhaul (IAB)), such as a base station, an evolved Node B, eNB in LTE, gNB in NR. Additionally, the network node disclosed herein refers to a RAN node for 6G. The RAN node for 6G may be called as 6gNB. In one or more examples, the RAN node is a functional unit which may be distributed in several physical units.

[0035] As discussed in detail herein, the present disclosure relates to a wireless communication system 1 comprising a cellular system, for example, a 3GPP wireless communication system. The wireless communication system 1 comprises a wireless device 300 and / or a network node 400.

[0036] A network node disclosed herein refers to a radio access network node operating in the radio access network, such as a base station, an evolved Node B, eNBs, a next generation Node B, gNBs, and 6g Node B, 6gNB.

[0037] The wireless communication system 1 described herein may comprise one or more wireless devices 300, 300A, and / or one or more network nodes 400, such as one or more of: a base station, an eNB, a next generation Node B (gNB), 6g Node B (6gNB) and / or an access point. A wireless device may refer to as a mobile device and / or a user equipment, UE.

[0038] The wireless device 300, 300A may be configured to communicate with the network node 400 via a wireless link (or radio access link) 10, 10A. The wireless devices 300, 300A may for example be seen as a first wireless device 300 and a second wireless device 300A respectively.

[0039] The wireless communication system 1 for example comprises a server device 600. The server device 600 may for example comprise a memory circuitry, a processor circuitry and / or a wireless and / or wired interface. The network node 400 may be configured to communicate with the server device 600 via a wireless link (or radio access link) 12.

[0040] Fig. 2A illustrates an example sub-band full duplex (SBFD) operation for context and understanding of the present disclosure. The sub-band full duplex can be seen as sub-band Frequency Division Duplexing (FDD) frame (e.g., unit, subframe, symbol) inserted into a Time Division Duplexing (TDD) system. The SBFD of Fig. 2A comprises a downlink sub-band 26, a frequency gap 27, and an uplink sub-band 28. Fig. 2A further shows slots 21-23 configured for a first wireless device (WD) 300 and a second wireless device (WD) 300A respectively, where slots 21 are downlink slots, such as slots for downlink transmission, slots 22 are guard slots X slots, and slots 23 are uplink slots, such as slots for uplink transmission. The slots 21-23 in Fig. 2A are an example of time units in the present disclosure. For example, the term "slot" disclosed herein may be replaced as "symbol", "subframe", or "radio frame". As can be seen in Fig. 2A, the configuration of the first WD 300 is DL heavier than the configuration of the second WD 300A. In other words, the configuration of the first WD 300 comprises more DL slots 21 than the configuration of the second WD 300A. Correspondingly, the configuration of the second WD 300A is UL heavier than the configuration of the first WD 300. In other words, the configuration of the second WD 300A comprises more UL slots 23 than the configuration of the first WD 300. Fig. 2A shows a downlink slot 25, and an uplink slot 29. In the downlink slot 25, both the first WD 300 and the second WD 300A are configured to communicate in DL. In the uplink slot 29, both the first WD 300 and the second WD 300A are configured to communicate in UL. In the remaining slots however, only one of the WDs is configured to communicate in either DL or UL. By using full TDD, only one WD would be able to communicate in these slots. Inserting the FDD frames 26-28 into the TDD system enables a plurality of WDs (e.g., 300, 300A) having different TDD configurations, such as a first WD 300 having a DL heavy TDD configuration and a second WD 300A having an UL heavy TDD configuration, to simultaneously communicate in slots where the first WD 300 is configured for DL communication and the second WD 300A is configured for UL communication. In TDD, a slot is used either for UL or DL communication. By inserting the FDD frames 26-28 having a first sub-band 26 for DL communication and a second sub-band 28 for UL communication, the WDs having different TDD configurations can communicate in the same time slot using respective FDD sub-bands. To avoid interference between the DL sub-band 26 and the UL sub-band 28, a frequency gap 27 may be added between the DL sub-band 26 and the UL sub-band 28 in a frequency domain.

[0041] The SBFD disclosed herein may be used for any physical channels (i.e. , Physical Downlink Control Channel (PDCCH), Physical Downlink Shared Channel (PDSCH), Physical Uplink Control Channel (PUCCH), Physical Uplink Shared Channel (PUSCH)). Alternatively, the SBFD may be used only for specific physical channels (e.g., a combination of control channels (PDCCH and PUCCH) or a combination of shared channel (PDSCH and PUSCH)).

[0042] The network node and / or wireless device of the wireless communication network, such as the wireless communication network 1 shown in Fig. 1 , may for example be configured to communicate according to SBFD, FDD, and / or TDD.

[0043] For example, the sub-band full duplex operation shown in Fig. 2A may be an operation between two network nodes, two wireless devices and / or one wireless device and one network node. The x-axis indicates time (t), and the y-axis indicates frequency (f).

[0044] The type of duplexing operation performed by the wireless device may for example be transparent to the wireless device, since as wireless device may not need to know whether the network node is performing TDD, FDD, or SBFD. The wireless device may transmit and / or receive control data and / or user data at the configured resource blocks without having obtained information indicative of the type of duplexing operation performed at the network node. However, it may be appreciated that the filtering performance of a neighbouring sub-band, such as the UL sub-band, may directly impact the performance of the SBFD. This impact of the performance of the SBFD may be associated with, such as influence, the guard gap 27 (e.g., configured by the network node) between the DL sub-band 26 and UL sub-band 28. Fig. 2B shows a graph illustrating the relationship between the actual filtering performance of the wireless device, the ACLR mask, and guard resource blocks, for context and understanding of this disclosure.

[0045] Fig. 2B shows a line 30, an ACLR mask 31 , a first guard resource block 32, a target resource block 33, a second guard resource block 34, and dotted lines 35, 36.

[0046] The x-axis of the graph shown in Fig. 2B indicates the Frequency in Megahertz, MHz, and the y- axis indicates the power in decibel milliwatts, dBm.

[0047] The ACLR mask 31 is for example indicative of a receive power limit of the received transmission and / or a transmit power limit of the transmission, e.g., a transmit power limit of the network node.

[0048] The first guard resource block 32 and the second guard resource block 34, are for example indicated by a resource block pre-configuration, e.g., provided by the network node. The first guard resource block 32 is for example characterized by one or more resource block parameters, e.g., comprised in the resource block pre-configuration. The second guard resource block 34 is for example characterized by one or more resource block parameters, e.g., comprised in the resource block pre-configuration. It may be appreciated that the first guard resource block 32 is smaller than the second guard resource block 34.

[0049] Line 30 can be seen as indicating the actual filtering performance of the wireless device of the wireless communication network. As is shown in Fig. 2B, the first guard resource block 32 guards, such as blocks, transmissions having a frequency of approximately between -1 MHz and -0.2MHz relative to the reference frequency indicated by the target resource block 33, shown as 0MHz on the x-axis. The first guard resource block 32 blocks out of band emissions, such as transmissions outside of the frequency indicated by the target resource block 33, with a relative power of up to approximately -50dBm (as indicated by dotted lines 35). In other words, the dotted lines 35 indicate that the filtering level, such as filtering level, of the first guard resource block 32 is -50dBm.

[0050] The second guard resource block 34 guards, such as blocks, transmissions having a frequency of approximately between +0.45MHz and +0.2MHz relative to the reference frequency indicated by the target resource block 33, shown as 0MHz on the x-axis. The second guard resource block 34 blocks out of band emissions, such as transmissions outside of the frequency indicated by the target resource block 33, with a relative power of up to approximately -44dBm (as indicated by dotted lines 35). In other words, the dotted lines 35 indicate that the filtering level, such as filtering level, of the second guard resource block 32 is -44dBm. The dotted line 36 indicates the actual emission level for the signal indicated by line 30. In Fig. 2B, the dotted line 36 indicates an actual emission level of approximately 12dBm. The target resource block 33 for example indicates the bandwidth for which the actual emission level indicated by dotted line 36 can be achieved.

[0051] Figs. 3A-3B show a flow diagram of an example method 100, performed by a network node according to the disclosure, e.g., for improving usage of band resources, such as sub-band resources. The network node is the network node disclosed herein, such as network node 400 of Fig. 1 , Fig. 5, and Fig. 7.

[0052] The method 100 comprises indicating S104, to a wireless device, a triggering indication.

[0053] Indicating S104, to a wireless device, a triggering indication for example comprises transmitting, e.g., to the wireless device, the triggering indication. The triggering indication may be seen as a trigger, such as for triggering (e.g., initiating) one or more operations of the wireless device. In other words, a triggering indication may be seen as an indication for triggering a wireless device to perform one or more operations of the wireless device.

[0054] In one or more example methods, the triggering indication triggers the wireless device to transmit, to the network node, a capability report comprising information indicative of the first filtering performance of the wireless device.

[0055] In some examples, the wireless device can transmit, such as report, to the network node, its filtering performance. The filtering performance may be per-band capability. In other words, the wireless device can transmit, such as report, to the network node, the filtering performance of the wireless device per bandwidth capability. In some examples, the wireless device may transmit such as report, to the network node, how much filtering (e.g., actual filtering) the wireless device can achieve based on different resource block lengths and / or different resource block locations.

[0056] For example, the wireless device may determine a difference between a target filtering performance and an actual filtering performance, such the first filtering performance. The target filtering performance may for example be transmitted to the wireless device from a network node. In other words, the wireless device may for example be configured according to a target filtering performance received from a network node. The wireless device may for example determine the difference between the target filtering performance and the actual filtering performance for one or more bands of a given bandwidth configuration. The wireless device may then transmit, such as report e.g., in the capability report, to the network node the difference between the target filtering performance and actual filtering performance. The target filtering performance may for example be seen as a minimum filtering performance. In some examples, the target filtering performance (such as the minimum filtering performance) may be set out in a specification, such as the 3GPP specification.

[0057] In one or more example methods, the triggering indication indicates a pre-configuration indicative of a resource block pre-configuration.

[0058] The pre-configuration for example comprises a resource block, RB, pre-configuration. The resource block pre-configuration can for example be seen as a configuration of resource blocks according to which the wireless device operates. In other words, the pre-configuration may be seen as a configuration according to which the wireless device is configured, e.g., prior to obtaining performance information, e.g., in S106. In other words, the network node may indicate to the wireless device the pre-configuration such that the wireless device may report its filtering performance based on the pre-configuration, such as according to the pre-configuration. In some examples, the resource block pre-configuration comprises one or more resource block allocations.

[0059] A resource block as disclosed herein may be seen as a contiguous set of subcarriers in the frequency domain and / or a time duration of transmission in the time domain. For example, the resource block comprises 12 consecutive subcarriers in the frequency domain. A resource block may comprise and / or be indicative of a resource band and a time resource, such as a time frequency resource. In other words, the resource block may comprise and / or indicate a range of frequencies and / or a combination of the range of frequencies and a time period.

[0060] The resource block disclosed herein may be associated with and / or indicative of a resource band. For example, the term resource block and resource band may be used interchangeably. The resource band may for example be seen as a frequency band, such as a range of frequencies. In other words, the resource band may be associated with one or more radio frequencies.

[0061] The resource block pre-configuration for example comprises a resource band (such as frequency band) pre-configuration and / or a time resource pre-configuration (e.g., one or more time periods).

[0062] In one or more example methods, the triggering indication comprises the pre-configuration. For example, the wireless device may be configured to, upon receiving the pre-configuration, transmitting the pre-configuration indicative of the resource block pre-configuration. In some examples, the triggering indication indicates the pre-configuration, e.g., via a look-up table, via corresponding values, etc. In one or more example methods, the resource block pre-configuration comprises one or more resource block parameters, the resource block parameters comprising one or more of: a resource block length parameter and a resource block location parameter.

[0063] The one or more resource block parameters can for example be seen as one or more parameters associated with the resource block, such as a resource block associated with a transmission between the network node and the wireless device.

[0064] The resource block length parameter may for example be indicative of a resource block length. In other words, the resource block length parameter may be indicative of the length of one or more resource blocks of the resource block pre-configuration. A resource block length parameter may be seen as a parameter indicative of a size and / or duration of a resource block, e.g., in the time domain. In other words, the resource block length parameter may be indicative of a specific duration or length of a resource block during which data or control signals may be transmitted.

[0065] The resource block location parameter is for example indicative of a resource block location. In other words, the resource block location parameter may be indicative of the location of one or more resource blocks of the resource block pre-configuration. A resource block location parameter may be seen as a parameter indicative of a specific frequency and / or time allocation assigned to a resource block within the system's spectrum and time domain. A resource block's location in the frequency domain may determine the range of frequencies over which the allocated resources are distributed.

[0066] The resource block parameters may for example be pre-determined. In some examples, the resource block parameters may for example be obtained, such as determined, by the network node. In some examples, the resource block parameters may be selected, such as customized, by a user.

[0067] In some examples, the resource block parameters comprise a resource block quantity parameter indicative of a number of resource blocks, e.g., the number of resource blocks in the frequency domain.

[0068] Additionally or alternatively, the resource block parameters may for example be signalled with TDD configuration information (e.g., TDD-Config IE). The TDD configuration information indicates TDD resources where the wireless device uses to transmit and / or receive one or more signals (e.g., physical signals, physical channels) and may comprises TDD slot configuration (e.g., DL slot, UL slot, Flexible slot). Furthermore, the resource block parameters and the TDD configuration information may be comprised in an RRC message which is transmitted from the network node to the wireless device. This may be one of the pre-configuration disclosed herein.

[0069] The method 100 comprises receiving S106, from the wireless device, performance information indicative of a first filtering performance of the wireless device.

[0070] Any operation (and / or any embodiment of any such operations) performed by the network node and / or the wireless device relating to the first filtering performance may (or may not) for example also relate to the second filtering performance. For example, in some examples the method 100 comprises receiving, from the wireless device, performance information, such as updated performance information, indicative of a second filtering performance of the wireless device.

[0071] Performance information may for example comprise information indicative of the filtering performance, such as a first filtering performance of the wireless device. In some examples, filtering performance, such as the first filtering performance, can be seen as a filtering level, (e.g., an actual filtering level, such as a measured filtering level and / or performance) of the wireless device. A filtering performance of a wireless device may be seen as its ability to effectively filter out unwanted signals or interference from received and / or transmitted signals, e.g., allowing the wireless device to receive, process, and / or transmit signals with reduced distortion or degradation in performance. For example, a filtering performance of a wireless device may be indicative of an out-of-band rejection, which is the ability of the wireless device's filter to attenuate signals outside a desired and / or allocated frequency band. A high out-of-band rejection may ensure that signals from adjacent frequency channels or spurious emissions do not interfere with the device's operation. A filtering performance of a wireless device may be seen as the wireless device’s capability to stand against a certain blocking signal level. To stand against a certain blocking signal level may be seen as a capability to filter out an interference signal. The performance information may for example comprise one or more of: an out-of-band rejection performance, an in-band emission loss performance, a stopband attenuation, a group delay variation performance, a passband ripple performance, emission mask, in-band emission level, out of band emission level, ability of standing against certain in band and out of band blocking signal level, ACS, ACLR and a dynamic range performance.

[0072] In some examples, the performance information comprises one or more performance parameters indicative of the first filtering performance of the wireless device. The one or more performance parameters for example comprise an Adjacent Subcarrier Channel Selectivity (ASCS) parameter, e.g., associated with a given frequency band. The ASCS parameter may for example be configured with one or more resource blocks associated with a frequency band. ASCS for example characterizes, such as indicates, the wireless device filtering performance within the frequency bands e.g., when it is configured with a few resource blocks in the middle of the band, e.g., when associated with a LP-WUS.

[0073] The first filtering performance is for example obtained, such as determined, retrieved, and / or received, by the wireless device.

[0074] The first filtering performance can for example be reported dynamically to the network node by the wireless device with respect to a network node configured resource allocation. In other words, the first filtering performance can for example be reported by using PUCCH or PUSCH as L1 (Layer 1) parameter(s). In some examples, the first filtering performance is associated with a filtering capability of the wireless device. The first filtering performance of the wireless device can be seen as the filtering performance of the wireless device based on the triggering indication, e.g., resource block pre-configuration, such as for one or more bands of a given bandwidth configuration.

[0075] In one or more example methods, receiving S106 the performance information comprises receiving S106A the capability report.

[0076] The capability report can for example be seen as a report indicative of the filtering capability of the wireless device. The capability report may for example be seen as a filtering capability report. The capability report can for example be comprised in an RRC message "UE Capability Information" which is transmitted from the wireless device to the network node in response to signalling of an RRC message "UE Capability Enquiry" which is transmitted from the network node to the wireless device.

[0077] In some examples, the wireless device transmitting to the network node the capability report can be seen as the wireless device reporting a filtering capability of the wireless device to the network node. In some examples, the filtering capability is based on the first filtering performance of the wireless device.

[0078] In some examples, the filtering capability of a wireless device may be seen as an inherent characteristic and / or property of the wireless device, e.g., based on hardware capabilities of the wireless device. In other words, the filtering capability of the wireless device may be seen as a static filtering capability of the wireless device, such as for one or more bands of a given bandwidth configuration (e.g., per band per band combination).

[0079] The capability report may comprise one or more indicators of capability of the filtering performance of the wireless device. For example, the capability report may indicate one or more of: out-of-band emission Adjacent channel leakage ratio, ACLR, Adjacent channel selectivity, ACS, and adjacent subcarrier channel selectivity ASCS. The capability report may for example be obtained for uplink and / or downlink.

[0080] The method 100 comprises transmitting S114, to the wireless device, a resource block configuration after receiving the performance information.

[0081] In some examples, the method 100 comprises transmitting, to the wireless device, a resource block configuration in response to receiving the performance information, such as the performance indicative of the first filtering performance of the wireless device. In some examples, the resource block configuration may be based on the performance information.

[0082] The resource block configuration may for example comprise information indicative of the configuration of one or more resource blocks. For example, the resource block configuration can be seen as a configuration of resource block resources. In other words, transmitting S114, to the wireless device, the resource block configuration after receiving the performance information comprises transmitting S114, to the wireless device, information indicative of a configuration of one or more resource blocks after receiving the performance information.

[0083] The resource block configuration may be seen as an SBFD configuration. In one or more examples, the resource block configuration may be comprised in the TDD configuration information.

[0084] The resource block configuration for example comprises a resource band (such as frequency band) configuration, a time resource configuration (e.g., one or more time periods), and / or the frequency gap for SBFD.

[0085] The network node may for example be able to reduce, based on the performance information, the gap band and / or resource blocks between sub-bands, such as between two sub-bands.

[0086] For example, the network node may be configured to determine, e.g., based on the received performance information (such as the received capability report), the resource block configuration.

[0087] In some examples, transmitting S114 the resource block configuration comprises transmitting, based on the received capability report, the resource block configuration after receiving the capability report.

[0088] In one or more example methods, the pre-configuration comprises a target filtering parameter indicative of a target filtering level. The target filtering parameter may be indicative of a targeted filtering level. For example, the target filtering parameter may indicate an amount of filtering, such as a desired amount of filtering.

[0089] In one or more example methods, the target filtering parameter comprises one or more of: a target Adjacent Channel Selectivity and a blocking level. In one or more example methods, the performance information comprises a guard resource block based on the target filtering parameter.

[0090] In one or more example methods, the target filtering parameter comprises one or more of: a target Adjacent Channel Selectivity (ACS), blocking level, a target Adjacent Channel Leakage Ratio (ACLR).

[0091] The target Adjacent Channel Selectivity may for example be a target measure of the receiver’s, such as the wireless device’s, ability to receive a signal at its assigned channel frequency in the presence of a strong signal in the adjacent channel.

[0092] The blocking level can for example be seen as a level of blocking, such as a target level of blocking. The blocking level may for example indicate a power value of blocked transmissions outside of the resource block within which the wireless device is configured to receive at a given time. The blocking level may in some examples be seen as an interference level, such as an interference level associated with an interference signal. The blocking level may for example be seen as a rejection level, e.g., indicative of a level (e.g., dB) of rejection for signals in a given frequency band.

[0093] For example, when the blocking level is 40 decibels (dB) for a given frequency band, then any signal arriving in this band may be attenuated by 40dB, e.g., before further processed of the WD".

[0094] The target ACLR is for example may be seen indicative of the amount of energy that leaks from a transmitter's, such as the network node, main channel to adjacent channels in a communication system.

[0095] The guard resource block may for example be seen as a resource block configured for blocking signals within a given bandwidth. For example, the guard resource block may prevent the wireless device from receiving transmissions within a given bandwidth, such as a guard resource band. In some examples, the bandwidth, such as the guard resource band and / or guard resource block, is based on the target filtering parameter. In some examples, the guard resource block is based on one or more of: a target Adjacent Channel Selectivity, a blocking level and / or a target Adjacent Channel Leakage Ratio (ACLR).

[0096] On the DL side, the network may for example set, such as select, one or more target ACS and / or blocking levels. The wireless device may for example report the demanded guard resource band to the network so that it can meet the target ACS or blocking level.

[0097] In one or more example methods, the target filtering parameter comprises a first criterion associated with the target filtering level.

[0098] In other words, the target filtering level can be seen as being indicated by the first criterion. For example, the first criterion may be seen as a criterion indicative of the target filtering level. The first criterion may for example be based on a per band per band combination and / or a per frequency per frequency combination. In other words, the first criterion may be associated with a target filtering level based on a per band per band combination and / or a per frequency per frequency combination.

[0099] In one or more example methods, the first criterion is based on a first threshold. In some examples, whether the first filtering performance satisfies the first criterion depends on whether the first filtering performance is greater than or equal to the first threshold. For example, when the first filtering performance is less than the first threshold, the first criterion can be seen as being satisfied by the first filtering performance. For example, when the first filtering performance is greater than the first threshold, the first criterion can be seen as not being satisfied by the first filtering performance. The first threshold may for example comprise ACS, ACLR, and / or blocking level. For example, the first criterion may be based on ACS, ACLR, and / or blocking level.

[0100] For example, when the first criterion is based on ACS, when the first filtering performance is greater than the first threshold, the first criterion can be seen as being satisfied by the first filtering performance. For example, when the first criterion is based on ACLR, the when the first filtering performance is greater than the first threshold, the first criterion can be seen as not being satisfied by the first filtering performance.

[0101] In some examples, the first criterion may be based on any limitation on emission and / or blocking level out of the resource block configuration, e.g., the resource band configuration.

[0102] For example, the first criterion may comprise a dB value, such a dB value (such as a dBm value) between 30-40dB. The dB value may for example be between 40-50dB. In some examples, the dB value is greater than or equal to 50dB. For example, the dB value may be between 50 and 70dB.

[0103] For example, the first criterion is for example indicated in Fig. 2B by the dotted lines 35, as the points where the dotted lines 35 intersect the y-axis at values of approximately -44dBm and - 50dBm.

[0104] The network node may for example indicate to the wireless device the target filtering level such that wireless device can determine how many guard resource blocks that would enable the filtering performance to meet the first criterion. In other words, the wireless device may be configured to determine, based on the target filtering level, e.g., transmitted by the network node, a number, length, and / or location of guard resource blocks that would enable the filtering performance to satisfy the first criterion.

[0105] The network node may select one or more target filtering parameters comprising the first criterion (e.g., based on ACS, ACLR, and / or blocking levels). The wireless device may for example report the targeted guard resource block to the network so that it can meet the first criterion (e.g., based on ACS, ACLR, and / or blocking levels.

[0106] In one or more example methods, the method comprises determining S110 whether the first filtering performance satisfies the first criterion.

[0107] In one or more example methods, the method 100 comprises obtaining S112 the resource block configuration in accordance with the first filtering performance satisfying the first criterion.

[0108] In one or more example methods, obtaining S112 the resource block configuration in accordance with the first filtering performance satisfying the first criterion comprises determining the resource block configuration in accordance with the first filtering performance satisfying the first criterion.

[0109] In some examples, obtaining S112 the resource block configuration in accordance with the first filtering performance satisfying the first criterion comprises adjusting the resource block configuration after receiving the performance information, e.g., in response to receiving the performance information (such as the guard resource block) and / or based on the performance information (such as the guard resource block).

[0110] In one or more example methods, the method 100 comprises obtaining the resource block configuration based on the outcome of determination of whether the first filtering performance satisfies the first criterion. In one or more example methods, the method 100 comprises refraining S111 from obtaining the resource block configuration in accordance with the first filtering performance not satisfying the first criterion.

[0111] In one or more example methods, the capability report comprises information indicative of the filtering capability for one or more bands of a given bandwidth configuration.

[0112] In some examples, the capability report comprises information indicative of the filtering capability for one or more bands of a give bandwidth combination. For example, the capability report comprises information indicative of the filtering capability for a combination of one or more bands, e.g., of one or more bandwidths.

[0113] In other words, the capability report for example comprises information indicative of a filtering performance per resource band (such as frequency band) and / or per band combination. For example, the capability report comprises information indicative of a static filtering capability of the wireless device per resource band and / or per band combination.

[0114] In other words, the capability report may be seen as being indicative of a filtering performance for one or more, such as each, resource bands of one or more, such as each, bandwidth combinations. For example, the filtering capability may correspond with the filtering performance of the wireless device.

[0115] In one or more example methods, the capability report indicates a filtering category associated with the first filtering performance of the wireless device.

[0116] The filtering category can for example be seen as a category for categorization of a first filtering performance, such as filtering capability, of the wireless device. For, example, one or more of the (such as each of the) filtering categories correspond to different levels of filtering of the wireless device. In other words, the filtering category may comprise information indicating a particular level of filtering associated with the wireless device.

[0117] The filtering category associated with the wireless device may for example be based on the performance information. For example, the wireless device and / or the network node may determine (e.g., using a look-up table) which filtering category is associated with the wireless device. The filtering category with which the wireless device is associated may be stored in a table, such as a look-up table.

[0118] In some examples, the capability report (e.g., indicating the filtering category) may be transmitted to the network node by the wireless device in response to the triggering indication, e.g., the initial connection. The capability report may for example comprise one or more filtering categories, such as one or more standardized filtering capabilities. In some examples, the filtering capabilities can be seen as filtering level capabilities, e.g., indicative of a level of filtering capability of the wireless device. In one or more examples, the capability report comprises one or more categories other than the filtering categories e.g., in addition to one or more filtering categories.

[0119] In one or more example methods, the filtering category is associated with a spectral filter mask.

[0120] The spectral filter mask can for example be seen as a spectral mask, channel mask, and / or transmission mask. The spectral filter mask may for example be seen as being configured to reduce adjacent-channel interference by limiting excessive radiation at frequencies beyond a given bandwidth. In other words, the spectral filter mask may be configured to filter signals with a frequency in a given frequency range. The spectral filter mask may for example be associated with the first filtering performance of the wireless device. In other words, the first filtering performance of the wireless device may be related to the spectral filtering mask with which the wireless device is associated.

[0121] In some examples, the filtering category comprises a spectral filter mask, such as information indicative a spectral filter mask.

[0122] In one or more example methods, the method comprises adjusting S108, based on the performance information, a transmitting power of the wireless device, wherein the performance information is indicative of an out-of-band emission level.

[0123] The transmitting power of the wireless device can for example be seen an output power associated with a transmission of the wireless device. For example, the transmitting power of the wireless device may be seen as the transmitter power output associated with the transmission of a signal. In other words, the transmitting power can be seen the power associated with a transmitted signal at the moment of transmission from the wireless device.

[0124] The out of band emission level can for example be seen as the emission level outside of the bandwidth (e.g., number of resource blocks, such as resource blocks associated with the resource block configuration) that the wireless device is configured to transmit and / or receive.

[0125] In some examples, (e.g., in the Uplink case) the adjusting S108, the transmitting power of the wireless device comprises adjusting, based on the actual filtering performance of the wireless device, the transmitting power of the wireless device. The filtering performance and / or out-of- band emission level of the wireless device may be reported with different transmit powers. For example, the filtering performance and / or out-of-band emission level may correspond with a given transmit power of the wireless device.

[0126] For example, when the out of band emission level is too high, the network can configure the wireless device to transmit with a lower power level. For example, the network node may transmit, to the wireless device, a signal indicating a change in transmitting power of the wireless device.

[0127] In some examples, upon determining that the first filtering performance does not satisfy the first criterion, the method 100 comprises reducing the transmitting power of the wireless device, e.g., by transmitting to the wireless device an indication to reduce its transmitting power.

[0128] In one or more example methods, the method comprises indicating S116, to the wireless device, an updated triggering indication.

[0129] The updated triggering indication be seen as an updated trigger, such as for triggering (e.g., initiating) one or more operations of the wireless device. The updated triggering indication may for example comprise an updated pre-configu ration indicative of an updated resource block preconfiguration. In other words, the updated triggering indication may be seen as an updated indication for triggering a wireless device to perform one or more operations of the wireless device.

[0130] The method 100 for example comprises updating the triggering indication, e.g., updating the resource block configuration.

[0131] In one or more example methods, the method comprises receiving S118, from the wireless device, updated performance information indicative of a second filtering performance of the wireless device.

[0132] The updated performance information may for example comprise information indicative of a filtering performance, such as the second filtering performance of the wireless device. In some examples the second filtering performance can be seen as a filtering level, (e.g., an actual filtering level) of the wireless device. In some examples, the updated performance information comprises one or more performance parameters indicative of the second filtering performance of the wireless device.

[0133] The second filtering performance is for example obtained, such as determined, by the wireless device. The second filtering performance is for example obtained, such as determined, after the first filtering performance. In one or more example methods, obtaining S120, based on the updated performance information, an updated resource block configuration for the wireless device.

[0134] The updated resource block configuration may for example comprise information indicative of an updated configuration of the one or more resource blocks. For example, the updated resource block configuration can be seen as a configuration of resource block resources. In other words, transmitting S114, to the wireless device, the updated resource block configuration after receiving the performance information, such as indicative of the second filtering performance, comprises transmitting S114, to the wireless device, information indicative of an updated configuration of one or more resource blocks after receiving the performance information.

[0135] The updated resource block configuration may comprise one or more of: one or more updated resource block parameters and an updated target filtering parameter.

In some examples, the updated resource block configuration may be based on the performance information.

[0138] In one or more example methods, the first filtering performance and / or the second filtering performance is associated with a radio frequency filtering performance of the wireless device.

[0139] The radio frequency filtering performance can for example be seen as the filtering performance, e.g., performed by the wireless device, of information received as a radio frequency.

[0140] In one or more example methods, the method comprises determining S102 whether a network congestion parameter satisfies a second criterion associated with a network congestion.

[0141] The network congestion parameter can for example be seen as indicative of a congestion of the network, such as the network comprising the wireless device and the network node. In other words, the network congestion parameter may be related to, such as indicative of, the number of transmissions occurring in the network. The network congestion parameter can for example be seen as characterizing the congestion, such as busyness, of the network. In one or more example methods, the second criterion is based on a second threshold. In some examples, whether the network congestion parameter satisfies the second criterion depends on whether the network congestion parameter is greater than or less than the second threshold. For example, when the network congestion parameter is less than the second threshold, the second criterion can be seen as being satisfied by the network congestion parameter. For example, when the network congestion parameter is greater than the second threshold, the second criterion can be seen as not being satisfied by the network congestion parameter. The second threshold may for example comprise ACS, ACLR, and / or blocking level. For example, the second criterion may be based on ACS, ACLR, and / or blocking level.

[0142] For example, when the first criterion is based on ACS, when the first filtering performance is greater than the first threshold, the first criterion can be seen as being satisfied by the first filtering performance. For example, when the first criterion is based on ACLR, the when the first filtering performance is greater than the first threshold, the first criterion can be seen as not being satisfied by the first filtering performance.

[0144] In one or more example methods, upon the network congestion parameters not satisfying the second criterion, refraining S103 from indicating to the wireless device, the triggering indication.

[0145] In one or more example methods, the performance information is based on a spatial direction of one or more beams transmitted and / or received by the wireless device.

[0146] The spatial direction of the one or more beams can be seen as a direction which the one or more beams are pointed, e.g., aiming. For example, the performance of the one or more beams may differ based on the spatial direction of the one or more beams.

[0147] In some examples, the target filtering parameter is based on a spatial direction of one or more beams transmitted and / or received by the wireless device.
