## Title
In-device coexistence for new radio

## Abstract

A network control device, e.g., a gNB, receives a message from a communications device, e.g. a UE, indicating that the communications device is experiencing an in-device coexistence (IDC) problem, e.g. in the 52.6 GHz-71 GHz frequency range with respect to NR-U and WiGig. The message is one of: i) an IDC assistance message indicating that the victim system is Wi-Gig or ii) an antenna panel switch message requesting that the network control device instruct the communications device to change the antenna panel that it uses for uplink NR signaling. The network control device generates and sends a response message to the communications device including: a selected new frequency to be used by the communications device for uplink NR signaling or a selected different antenna panel to be used by the communications device for uplink NR signaling. The communications device implements the change reducing or avoiding the IDC problem.

## Background
RELATED APPLICATIONS
The present application is a continuation of U.S. patent application Ser. No. 17/175,389 filed Feb. 12, 2021 and which is hereby expressly incorporated by reference in its entirety.


FIELD
The present application relates to wireless communications methods and apparatus, and more particularly for method and apparatus for reducing or avoiding in-device coexistence (IDC) problems, e.g., in the frequency range of 52.6 GHz to 71 GHz.
BACKGROUND
A Release-17 Study Item (Rel-17 SI) on extending New Radio (NR) operation to the frequency range of 52.6 GHz-71 GHz has been in progress since May 2020. This SI targets utilization of the very wide unlicensed and licensed spectrum bandwidths in this frequency range.
The SI objectives include: i) the study of required changes in NR using existing downlink/uplink (DL/UL) NR waveform to support operation between 52.6 GHz and 71 GHz including the study of applicable numerology subcarrier spacing (SCS), channel bandwidth (BW) including maximum BW, and their impact to frequency range 2 (FR2) physical layer design to support system functionality considering practical radio frequency (RF) impairments, and ii) identify potential critical problems to physical signal/channels, if any.
The frequency range of 52.6 GHz-71 GHz is also used by other radio access technologies such as 802.11ad and 802.11 ay.
There is a separate Rel-17 work item (WI) on Further enhanced Multiple Input Multiple Output (FeMIMO) that covers multi-panel (MP) user equipment (UE) enhancements. A UE panel comprises a collection of transceiver units (TXRUs) that is able to generate one analog beam (one beam may correspond to two antenna ports if dual-polarized array is used). UE panels can constitute the same as well as different numbers of antenna elements and ports, number of beams and Effective Isotropic Radiated Power (EIRP). For facilitating fast uplink panel selection, the following use cases are assumed: Maximum Permissible Exposure (MPE) mitigation, UE power saving, UL interference management, support different configurations across panels and UL multi-Total Radiated Power (mTRP).
Both Long Term Evolution (LTE) and New Radio (NR) support in-device coexistence (IDC) mechanisms for a UE equipped with multiple radio transceivers that are physically proximate and operate on adjacent frequencies or sub-harmonic frequencies. The interference power coming from a transmitter of the collocated radio may be much higher than the actual received power level of the desired signal for a receiver, even after filtering. The UE invokes IDC reporting to its serving base station via dedicated radio resource control (RRC) signaling when it cannot solve the IDC issue by itself. For example, a Rel-16 NR UE can report IDC issues with Wireless Local Area Network (WLAN), Bluetooth, or Global Navigation Satellite System (GNSS) radios such as Global Positioning System (GPS).
In LTE, when notified of IDC problems, the eNB can choose to apply a Frequency Division Multiplexing (FDM) solution or a Time Division Multiplexing (TDM) solution, as shown in drawing 100 of FIG. 1. Drawing 100 of FIG. 1 shows LTE IDC phases. In step 102 the UE detects start of IDC interference and LTE IDC phase 1 103 begins. In step 104 the UE initiates the transmission of an IDC indication to an eNB and LTE IDC phase 2 105 starts. In step 106 the eNB provides a solution that solved the IDC problem and LTE IDC phase 3 107 starts.
The basic concept of a FDM solution is to move the LTE signal away from the Industrial Scientific Medical (ISM) band by, e.g., performing inter-frequency handover within E-UTRAN, removing SCells from the set of serving cells or de-activation of affected SCells, or in the case of uplink CA operation, allocating uplink Physical Resource Block (PRB) resources on Component Carrier(s) (CC(s)) whose inter-modulation distortion and harmonics does not fall into the frequency range of the victim system receiver. The basic concept of a TDM solution is to ensure that transmission of a radio signal does not coincided with reception of another radio signal. LTE Discontinuous Reception (DRX) mechanism is used to provide TDM patterns (i.e. periods during which the LTE UE may be scheduled or is not scheduled) to resolve the IDC issues. DRX based TDM solution should be used in a predictable way, i.e., the eNB should ensure a predictable pattern of unscheduled periods by means of, e.g., DRX mechanism or de-activation of affected SCells.
In the case of NR, the FDM solution from LTE is adopted. The NR UE indicates the affected frequencies to the network, which can then take further action to alleviate the solution. For the frequencies on which a serving cell of serving cells is configured that is activated, IDC problems consist of interference issues that the UE can solve by itself, during either active data exchange or upcoming data activity which is expected in up to a few hundred milliseconds. The UEAssistanceInformation RRC message is used or the indication of NR UE assistance information to the network, including IDC issues. Drawing 200 of FIG. 2 shows the UEAssistanceInformation RRC message format. FIG. 3 provides UEAssistanceInformation field descriptions in table 300.
RF IDC challenges with two transceivers WI-Gig and 60 GHz New Radio-Unlicensed (NR-U) will now be described. A typical UE architecture containing a WLAN WI-Gig module and a 60 GHz NR-U transceiver will have independent antenna arrays. The antenna isolation can be as low as 10 dB or higher depending on beam forming. The lower the isolation, the greater the inter-system interference. Some architectures will have two sets of antenna arrays, one for vertical polarization and another one for horizontal polarization (dual polarization). Antenna arrays can have 64-256 antenna elements. For 17-27 dBm power output, the module can have 16-64 Power Amplifiers (PAs). Spec can be 1 W/PA element.
FIG. 4 includes drawing 400 which illustrates a typical UE architecture block diagram 402 for a transmit/receive (TR) Block and an exploded view drawing 402′ of the TR block 402. The TR block 402 includes digital to analog converters (DACs) 407, mixers 407, a transmit phase array 404, an analog to digital converter (ADC) 409, a mixer 411, and a receive phase array 406. The transmit phase array 404 includes, an active and passive power splitter 408, phase shifters 410, power amplifiers 412 and antenna array 414 including a plurality of antennas 416, and a serial peripheral interface (SPI) controller 418 for controlling the PAs 412 and the phase shifters 410. The receive phase array 406 includes antenna array 426 including a plurality of antennas 428, low noise amplifiers (LNAs) 424, phase shifters 422, an active and passive combiner 420, and an SPI controller 430 for controlling the LNAs 424 and the phase shifters 422. Antenna isolation will be established between antenna phase arrays.
FIG. 5 illustrates an integrated phase array transceiver 500. Integrated phase array transceiver 500 includes assembly of components 501, antenna submodule controller 502 and external synthesizer 508 coupled together as shown. Assembly of components 501 includes a control and monitor interface 504, a beam control interface 506, a local oscillator (LO) distribution/doubler 510, upconverters 512, 514, downconverters 516, 518, a 1:16 passive combiner/splitter 520, and sixteen TR blocks (522, 524, 526, 528, 530, 532, 534, 536, 538, 540, 542, 544, 546, 548, 550, 552).
IDC interference can vary depending on antenna array configuration, number of PA elements per module and polarization techniques, but if the channelization assignment between NR-U and Wi-Gig are in close proximity, this interference might not be mitigated based on the above techniques, hence a solution to Rel-16 NR is needed for 60 GHz for the UE to be able to report IDC issues to the gNB.
Another RF challenge for co-existence between WiGig and 60 GHz NR-U is third order intermodulation (IM) or harmonic interference. Although synchronized networks can avoid this condition, it is difficult in some cases to have these networks synchronized.
In the scenario of FIGS. 6 and 7, a few assumptions are made for NR-U, min channel bandwidth is 400 MHz. This will help in identifying the channelization.
FIG. 6 is a drawing 600 including a first table 602 illustrating 60 GHz WiFi (Wi-Gig) channelization for 802.11ad and 802.11ay and a second table 604 illustrating 60 GHz NR-U channelization. First column 606 of table 602 includes channel numbers; second column 608 of table 602 includes center frequency (in GHz) for each channel; third column 610 of table 602 includes Minimum (Min) frequency (in GHz) for each channel; fourth column 612 of table 602 includes Maximum (Max) frequency (in GHz) for each channel; and fifth column 614 of table 602 includes bandwidth (BW) (in GHz) for each channel.

Items indicated in table 700 with an “*” are NR harmonics falling in the Wi-Gig band as a result of a third order intermodulation distortion (IMD) mechanism giving rise to inter-system interference.
A NR UE equipped with two transceivers in the 60 GHz band, such as IEEE 802.11ad/ay radios and NR operating in 52.6-71 GHz, may perceive IDC issues due to adjacent frequencies or sub-harmonic frequencies. NR does not currently support reporting of IDC issues with 802.11 ad/ay (WiGig). Based on the above discussion there is a need for new methods and apparatus to provide solutions with regard to IDC issues for this frequency band.
SUMMARY
Various method and apparatus, in accordance with the present invention, are directed to features to enhance new radio in-device coexistence (NR IDC) mechanisms in the frequency range 52.6 GHz-71 GHz. Various exemplary method and apparatus, in accordance with the present invention, are well suited for using in both a phone form-factor user equipment (UE) and an Integrated Access Backhaul (IAB) node with UE functionality.
A communications device, e.g. a UE with two transceivers, e.g. a WiGig transceiver and a 60 GHz NR-U transceiver, which detects an in-device coexistence (IDC) problem which it can not solve on its own, generates and sends a message to a network control device. The network control device, e.g. a gNB, receives the message from the communications device, e.g. UE, indicating that the communications device is experiencing an in-device coexistence (IDC) problem, e.g. in the 52.6 GHz-71 GHz frequency range with respect to NR-U and WiGig. The message is one of: i) an IDC assistance message indicating that the victim system is Wi-Gig or ii) an antenna panel switch message requesting that the network control device instruct the communications device to change the antenna panel that it uses for uplink NR signaling. In some embodiments, the communications device further communicates information, e.g., communications device preferred frequency or frequencies to use, communications device power amplifier (PA) characteristic information, and/or communications device preferred antenna panel or panels to switch to, to assist the network control device in making a decision. The network control device generates and sends a response message to the communications device including: a selected new frequency to be used by the communications device for uplink NR signaling or a selected different antenna panel to be used by the communications device for uplink NR signaling. The communications device implements the change in accordance with the response message, e.g., switching to a new NR uplink frequency or switching to a different antenna panel for uplink NR signaling, thus reducing or avoiding the previously detected IDC problem. Changing the frequency used if a frequency solution to the detected IDC problem. Changing the antenna panel is a spatial solution to the detected IDC problem.

DETAILED DESCRIPTION
An exemplary embodiment, in accordance with the present invention, introduces the changes necessary on higher level signaling (UEAssistanceInformation), e.g., includes a novel UEAssistanceInformation message, to report IDC issues with WiGig to the gNB in Rel-17. The gNB may, and sometimes does, respond to the UE by moving NR operation to a new frequency using existing or new mechanisms. FIG. 8 is a drawing 800 illustrating format of an exemplary novel UEAssistanceInformation message. UEAssistanceInformation message includes new information 802 for reporting with respect to the 52.6 GHz-71 GHz and include new victim type wigig 804.
In a further aspect of some embodiments, the UE may, and sometimes does, also indicate preferred new frequencies of operation, e.g. for its NR PSCell/SCells. The UE may, and sometimes does, also provide characteristics of its power amplifier(s) (e.g., power coefficient and harmonic frequencies) to assist a network control device, e.g. a gNB, in determining a new NR operating frequency. In some embodiments a list of preferred new frequencies of operation and/or characteristics of the power amplifier(s) are further included in the UE Assistance information message which reports IDC. In some other embodiments a list of preferred new frequencies of operation and/or characteristics of the power amplifier(s) are reported separately, e.g., in one or more additional messages, to the network control device, e.g. gNB, in addition to the UE Assistance information message which reports IDC, e.g., as supplement information to be used in selecting the new frequencies.
FIG. 9 is a drawing of a flowchart 900 of an exemplary method of operating a user equipment (UE) device in accordance with an exemplary embodiment. Operation starts in step 902 in which the UE is powered on and initialized. Operation proceeds from start step 902 to step 904. In step 904 the UE monitors for an in-device coexistence issues in frequencies above 52.6 GHz. Step may, and sometimes does, include step 906, in which the UE detects an in-device coexistence issue in frequencies above 52.6 GHz. Operation proceeds from step 906 to step 908.
In step 908 the UE determines if the UE can resolve the IDC issue by itself. If the UE determines that it can resolve the IDC issue by itself, then operation proceeds from step 908 to step 910, in which the UE performs operations to resolve the IDC issue by itself. However, if the UE determines that it cannot resolve the IDC issue by itself, then operation proceeds from step 908 to step 912.
In step 912 the UE generates and IDC assistance message. Step 912 includes step 914, and may, and sometimes does, include one or both of steps 916 and 918. In step 914 the UE device includes UE assistance information including: an affected carrier list and victim system type information identifying Wi-Gig (alternatively known as 60 GHz WiFi), e.g. UEAssistanceInformation-v1700 including: affectedCarrierCombList-r17, victimSystemType-r17 (wigig-r17), in the IDC assistance message. In step 916 the UE includes, in the IDC assistance message, information indicating preferred new frequencies of operation for its New Radio Primary Secondary Cell Group (SCG) Cell/Secondary Cells (NR PSCell/SCells). In step 918 the UE includes, in the IDC assistance message, characteristics of the UE's power amplifier, e.g. power coefficients and harmonic frequencies. Operation proceeds from step 912 to step 920.
In step 920 the UE sends the generated IDC assistance message to a network control device, e.g. a gNB. Step 920 includes step 922 in which the UE transmits the generated message over a wireless link. Operation proceeds from step 920 to step 924, in which the network control device, e.g. gNB, receives the IDC assistance message and recovers the communicated information. Operation proceeds from step 924 to step 926. In step 936 the network control device, e.g. gNB, determines a new NR operating frequency. In some embodiments, step 926 includes one or both of steps 928 and 930. In step 928 the network control device, e.g. gNB, uses the received indicated preferred new frequencies of operation for the UE's NR PSCell/SCells, in determining the new NR operating frequency to be used by UE. In step 930 the network control device, e.g. gNB, uses the received characteristics of the UE's power amplifier in determining the new NR operating frequency to be used by UE. Operation proceeds from step 932 to step 934.
In step 934 the network control device, e.g. gNB, sends the generated response message to the UE. Operation proceeds from step 934 to step 936. In step 936 the UE device monitors for a response message. Step 936 may, and sometimes does, include step 938, in which the UE device receives a response message to the previously sent IDC assistance message, said response message including instructions, e.g. information indicating the new frequency to be used by the UE with regard to NR uplink signaling, and information indicating when the switch is to occur. Operation proceeds from step 938 to step 940. In step 940 the UE device follows the instructions in the received response message from the network control device, e.g. the UE switches to the indicated new frequency for NR operation at the indicated time.
Operation proceeds from step 910 or step 940, via connecting node A 942, to the input of step 904.
A second exemplary embodiment includes a new mechanism for combating IDC for a multi-panel UE. The UE request the network to move its transmissions/receptions to one or more new UL panels. This is a space division multiplexing (SDM) approach, in addition to the time division multiplexing (TDM) and frequency division multiplexing (FDM) techniques supported in LTE and NR. The UE may, and sometimes does, further provide the suggested panel IDs of the new panels. The network responds by initiating activation of a new UL panel(s). The net effect is to resolve IDC through increased antenna isolation. An example with a two-panel UE 1002, which includes antenna panel A 1004 and antenna panel B 1006, is shown in drawing 1000 of FIG. 10. Drawing 1001 illustrates a first step 1052 in which the UE 1002, which is using panel A 1004, as indicated by dotted shading, detects an in-device coexistence (IDC) issue with regard to using panel A 1004. Drawing 1003 illustrates a second step 1054 in which the UE 1002 requests the network to move it to a new UL panel, as indicated by arrow 1010. Drawing 1005 illustrates a third step 1056 in which the network moves the UE 1002 to panel B 1006, as indicated by dotted shading of panel B 1006, and the IDC issue is resolved.
FIG. 11 a flowchart 1100 of an exemplary method of operating a multi-panel UE in accordance with an exemplary embodiment. In step 1102 the UE is powered on and initialized. Operation proceeds from start step 1102 to step 1104. In step 1104, which is performed repetitively on an ongoing basis, the UE monitors for an in-device coexistence issue in the frequencies above 52.6 GHz. Step 1104, may, and sometime does include step 1106, in which the UE detects an in-device coexistence (IDC) issue in frequencies above 52.6 GHz. Operation proceeds from step 1106 to step 1108.
In step 1108 the UE determines if the UE can resolve the IDC panel issue by itself. If the UE determines that it can resolve the IDC panel issue by itself, then operation proceeds from step 1108 to step 1110, in which the UE performs one or more operation to resolve the panel IDC issue by itself. In some embodiments, step 1110 includes operating the UE to switch the antenna panel used for Wi-Gig to another antenna panel.
However, if the UE determines that it cannot resolve the panel IDC issue by itself, then operation proceeds from step 1108 to step 1112, in which the UE generates a panel switch request message. Operation proceeds from step 1112 to step 1114.
In step 1114 the UE device sends the generated panel switch request message to a network control device, e.g., a gNB. In some embodiments, step 1114 includes step 1116 in which the UE transmits the generated panel switch request message over a wireless link. Operation proceeds from step 1114 to step 1118.
In step 1118 the network control device, e.g. gNB, receives the panel switch request message and recovers the communicated information, e.g. a request for a panel switch and optionally information indicated a UE preferred panel or preferred set of panels to be used. Operation proceeds from step 1118 to step 1120. In step 1120 the network device generates a response message, said response message being a response to the panel switch request message. The response message includes, e.g., information identifying a new panel or new set of panels to be used by the UE and optionally information, indicating when the panel switch is to be implemented by the UE. Operation proceeds from step 1120 to step 1122. In step 1122 the network control device sends the generated response message to the UE. Operation proceeds from step 1122 to step 1124.
In step 1124 the UE device monitors for a response message. Step 1124 may, and sometimes does, include step 1126, in which the UE device receives a response message in response to the previously sent panel switch request message and recovers the information communicated in the response message, e.g. information indicating that the switch request is being granted and instructions for implementing the switch including information identifying the new panel or panels to be used and information identifying when to implement the switch. Operation proceeds from step 1126 to step 1128.
In step 1128 the UE device follows the instructions in the received panel switch response message from the network control device, e.g. switching to the new panel or panels at the appropriate time. Subsequently, the new antenna panel or panels are used by the UE for uplink NR signaling. Operation proceeds from step 1110 or 1128, via connecting node A 1130, to step 1104.
FIG. 12, comprising the combination of FIG. 12A, FIG. 12B, FIG. 12C and FIG. 12D, is a flowchart 1200, of an exemplary method of operating a communications system, e.g., a communications system supporting communications within the frequency range of 52.6-71 GHz and in which multiple different communications networks, e.g., a WiGig network and a NR cellular network may operate concurrently, in accordance with an exemplary embodiment. Operation starts in step 1202, in which the communications system is powered on and initialized. Operation proceeds from start step 1202 to step 1204.
In step 1204 a first communications device, e.g., a first user equipment (UE), detects an in-device coexistence (IDC) problem. The first communications device includes multiple radio transceivers, and at least one of the multiple radio transceivers is capable of operating at one or more frequencies within a first frequency band, e.g., a frequency band with the range of 52.6 GHz-71 GHz. In some embodiments, at least two of the multiple radio transceivers in the first communications device are capable of operating at one or more frequencies within the first frequency band. Operation proceeds from step 1204 to step 1206.
In step 1206 the first communications device generates a first in-device coexistence (IDC) assistance message. Step 1206 includes step 1208, in which the first communications device includes, in the first IDC assistance message, information indicating a wigig victim type. In some embodiments, step 1206 includes one or both of steps 1210 and 1212. In step 1210 the first communications device includes, in the first IDC assistance message, information indicating one or more new frequencies that the first communications device would prefer to use in a first frequency band (e.g., within a 52.6 to 71 GHz frequency band). In step 1212 the first communications device includes, in the first IDC assistance message, UE power amplifier (PA) characteristic information indicating one or more new characteristics of a power amplifier included in the first communications device. Operation proceeds from step 1206 to step 1214.
In step 1214 the first communications device transmits the generated first IDC assistance message to a network control device, e.g. a gNB. Operation proceeds from step 1214 to step 1215. In step 1215 the network control device, e.g., gNB, is operated to monitor for messages. Operation proceeds from step 1215 to step 1216.
In step 1216 the network control device, e.g. a gNB, receives the first IDC assistance message from the first communications device, e.g. first UE, which detected an in-device coexistence problem, said first IDC assistance message indicating a wigig victim type. Step 1216 may, and sometimes does, include one or both of steps 1218 and 1220. In step 1218 the network control device receives, in said first IDC assistance message, information indicating one or more new frequencies the first communications device would prefer to use in a first frequency bane (e.g., within a 52.6-71 GHz frequency band.) In step 1220 the network control device receives, in said first IDC assistance message, UE power amplifier (PA) characteristic information indicating one or more characteristics of a power amplifier included in the first communications device. Operation proceeds from step 1216 to step 1222.
In step 1222 the network control device selects one or more new frequencies to be used by the first communications device based on information included in the first IDC assistance message, said one or more new frequencies differing in at least one frequency from one or more frequencies in said first communications band that were being used by the first communications device when the first communications device detected said in-device coexistence problem. In some embodiments, step 1222 includes one or both of steps 1224 and 1226. In step 1224 the first communications device selects at least one frequency indicates in the first IDC assistance message as a preferred frequency, as one of said new frequencies. In step 1226 the first communications device selects at least some of the one or more frequencies to be included in the new frequencies based on the power amplifier information included in the first IDC assistance message. Operation proceeds from step 1222, via connecting node A 1228, to step 1230.
In step 1230 the network control device generates, a response message to the first communications device indicating the selected one or more new frequencies in the first frequency band to be used by the first communications device. Operation proceeds from step 1230 to step 1232.
In step 1232 the network control device transmits the generated response message to the first communications device, said response message indicating the selected one or more new frequencies in the first communications band to be used by the first communications device. Operation proceeds from step 1232 to step 1234.
In step 1234 the first communications device receives the response message sent from the network control device and recovers the communicated information, said response message being a response to the first IDC assistance message. Operation proceeds from step 1234 to step 1236.
In step 1236 the first communications device transmits data using the one or more frequencies to the network control device, e.g., gNB, for forwarding to another communications device, e.g. a second UE, as part of a communications session between the first communications device, e.g., the first UE, and the another communications device, e.g., the second UE. Operation proceeds from step 1236 to step 1238.
In step 1238 the network control device, e.g., gNB, receives the data transmitted by the first communications device and forwards, e.g. sends, the received data, e.g. via a communications network, e.g. a backhaul network and/or the Internet (e.g., first and second UE are coupled to different gNBs), or over the air (e.g., first UE and second UE are coupled to the same gNB), to another communications device, e.g., the second UE. Operation proceeds from step 1238, via connecting node B 1240 to step 1242.
In step 1242 a second communications device, e.g., a UE including a plurality of antenna panels, detects an IDC problem which can be resolved by changing an antenna panel or panels used for uplink communications. Operation proceeds from step 1242 to step 1244. In step 1244 the second communications device generates a panel switch message. In some embodiments, step 1244 includes steps 1246 and 1248. In step 1246 the second communications device determines, e.g. based on knowledge of the available antenna panels at the second communications device and/or knowledge of the direction or sources of interference causing the IDC problem, one or more alternative antenna panels which can be used for uplink communications to avoid or reduce the detected IDC problem. Operation proceeds from step 1246 to step 1248, in which the second communications device includes in the panel switch message information indicating one or a set of antenna panels which can be used by the second communications device to avoid or reduce the detected IDC problem.
In some embodiments, step 1244 includes step 1250 in which the second communications device includes, in the panel switch message, information indicating one or a set of antenna panels that second communications device is recommending switching to (e.g., the second device makes panel switch recommendations but the ultimate decision to perform a panel switch is made by the network control device). In some embodiments, step 1244 includes step 1252 in which the second communications device includes, in the panel switch message, information indicating one or a set of antenna panels that second communications device is switching to (e.g., the second communications device, which has the authority to make and implement panel switch decisions, is notifying the network control device that it is performing a panel switch operation). Operation proceeds from step 1244 to step 1254.
In step 1254 the second communications device transmits the generated panel switch message from the second communications device to the network control device. Operation proceeds from step 1254 to step 1256.
In step 1256 the network control device, e.g. gNB, receives the panel switch message from the second communications device, e.g. second UE, that supports space division via the use of multiple antenna panels, said panel switch message including: i) a request that the network control device switch the antennal being used by the second communications device for uplink communications between the second communications device and the network control device or ii) a notification that the second communications device is switching the antenna panel being used by the second communications device for uplink communication between the second communications device and the network control device, to a second communications device selected antenna panel. In some embodiments, step 1256 includes one of step 1258 and 1260. In step 1258 the network control device receives, in the panel switch message, information indicating one or a set of antenna panels that the second communications device is recommending switching to (e.g., the second communications device has sent a recommendation of a panel switch to the network control device, but the network control device is the device with the authority to make panel switch decisions and may, and sometimes does, act on the recommendation). In step 1260 the network control device receives, in the panel switch message, information indicating one or a set of antenna panels that the second communications device is switching to (e.g., the second communications device, which has the authority, has made a panel switch decision and notifies the network control device of the impending panel switch).
In some embodiments, e.g., an embodiment, in which the network control device is the device with the authority to make panel switch decisions, operation proceeds from step 1256, via connecting node C 1262 to step 1264. In some embodiments, e.g., an embodiment, in which the second communications device has the authority to make and implement panel switch decisions, operation proceeds from step 1256, via connecting node C 1262 to step 1272.
Returning to step 1264, in step 1264 the network control device, in response to receiving the panel switch request, decides to switch the second communications device to a different antenna panel for uplink communications. Step 1264 may, and sometimes does, includes step 1266 in which the network control device selects the antenna panel, to which the second communications device is to switch, from one or more of the antennal panels identified by the second communications device (as candidates for the antenna panel switch), in said panel switch message. Operation proceeds from step 1264 to step 1268.
In step 1268 the network control device transmits, to the second communications device, a switch instruction with an indication of the antenna panel to which the UE is to switch for uplink communications. Operation proceeds from step 1268 to step 1270.
In step 1270 the second communications device, receives the switch instruction with an indication of the antenna panel to which the second UE is to switch for uplink communications. Operation proceeds from step 1270 to step 1272.
In step 1272 the second communications device switches to one or more new antenna panels, e.g., in accordance with its decision as to which antenna panel to switch to, or in accordance with information in the received switch instruction from the network control device, e.g., gNB. Operation proceeds from step 1272 to step 1274. In step 1274 the second communications device transmits uplink data to the network control device, e.g., the gNB, using the one or more new antenna panels. For example, the transmitted uplink data is data intended for another communications device, which is in a communications session with the second communications device, and the network control device, e.g. gNB, is to forward the data toward the another communications device via a backhaul network and/or the Internet, or via a wireless downlink signal to the another communications device.

The network control device, e.g., gNB, responds to the IDC assistance message with a response message indicating one or more new frequencies to be used by the UE. The UE implements the change and uses the new frequencies for UL NR signaling to the NR base station, thus reducing or eliminating the IDC problem.
In some embodiments, a communications device, e.g. a UE, including multiple switchable antenna panels (e.g., for UL NR transmissions in 60 GHz NR spectrum) which detects an IDC problem with regard to Wi-Gig (60 GHz WiFi), e.g., which it can not handle on its own, generates and sends an panel switch request message to a network control device, e.g., a gNB. In some embodiments, the panel switch request message includes information identifying a recommended panel or panels to which the UE would like to be switched to. The network control device, e.g. gNB, receives the panel switch request message and sends a response, e.g., a panel switch instruction message, notifying the UE that the panel switch request is being granted, identifying the antenna panel or panels to be used following the switch, and indicating when the switch is to be implemented. The UE implements the panel switch in accordance with the received instructions and uses the newly designated antenna panel(s) for UL NR signaling to the NR base station, thus reducing or eliminating the IDC problem.
