Information defining an operational environment in which a wireless device is operating may be obtained. Communication with the wireless device may be managed based on the information defining the operational environment in which the wireless device is operating. Related RAN nodes, computer programs, and computer program products are also discussed. ## Claims ### Claim 1 A method of operating a Radio Access Network, RAN, node of a wireless communication network, the method comprising: obtaining information defining an operational environment in which a wireless device is operating; and managing communication with the wireless device based on the information defining the operational environment in which the wireless device is operating. ### Claim 2 (depends on 1) The method of claim 1 further comprising: receiving a measurement of received signal quality and/or received signal power from the wireless device, wherein the measurement is a measurement of the received signal quality and/or the received signal power at the wireless device, and wherein communication with the wireless device is managed based on the information defining the operational environment in which the wireless device is operating and based on the measurement of the received signal quality and/or the received signal power. ### Claim 3 (depends on 2) The method of claim 2, wherein the received signal quality and/or the received signal power is for at least one beam received by the wireless device from the RAN node. ### Claim 4 (depends on 2) The method of claim 2, wherein the received signal quality and/or the received signal power comprises a Reference Signal Received Quality, RSRQ, and/or a Reference Signal Received Power, RSRP. ### Claim 5 (depends on 1) The method of claim 1, wherein managing communication comprises performing beam management for the wireless device based on the information defining the operational environment in which the wireless device is operating. ### Claim 6 (depends on 5) The method of claim 5, where performing beam management comprises performing beam adjustment and/or beam alignment for the wireless device based on the information defining the operation environment in which the wireless device is operating. ### Claim 7 (depends on 5) The method of claim 5, wherein performing beam management comprises selecting a beam for communication with the wireless device based on the information defining the operational environment in which the wireless device is operating, and communicating data with the wireless device using the beam selected for communication with the wireless device. ### Claim 8 (depends on 1) The method of claim 1, wherein the RAN node is a first RAN node, wherein managing communication comprises performing handover of the wireless device from the first RAN node to a second RAN node based on the information defining the operational environment in which the wireless device is operating. ### Claim 9 (depends on 1) The method of claim 1, wherein managing communication comprises performing carrier aggregation for the wireless device based on the information defining the operational environment in which the wireless device is operating. ### Claim 10 (depends on 9) The method of claim 9, wherein performing carrier aggregation comprises selecting at least one component carrier to provide carrier aggregation for the wireless device, and communicating data with the wireless device using the at least one component carrier selected to provide carrier aggregation. ### Claim 11 (depends on 1) The method of claim 1, wherein managing communication comprises controlling transmission of a reference signal based on the information defining the operational environment in which the wireless device is operating. ### Claim 12 (depends on 11) The method of claim 11, wherein controlling transmission comprises selecting a beam for the reference signal based on the information defining the operational environment in which the wireless device is operating, and transmitting the reference signal using the beam selected for the reference signal. ### Claim 13 (depends on 11) The method of claim 11, wherein the reference signal comprises at least one of a positioning reference signal, PRS, a channel state information reference signal, CSI-RS, and/or cell specific reference signal, CRS. ### Claim 14 (depends on 1) The method of claim 1, wherein the information defining the operational environment comprises an indication that the wireless device is in line of sight, LOS, or non-line of sight, NLOS, communication with the RAN node. ### Claim 15 (depends on 14) The method of claim 14, wherein obtaining the information defining the operational environment comprises receiving the indication that the wireless device in LOS or NLOS communication with the RAN node from the wireless device. ### Claim 16 (depends on 14) The method of claim 14, wherein obtaining the information defining the operational environment comprises receiving a representation of a power delay profile, PDP, from the wireless device, and determining the indication based on the representation of the PDP. ### Claim 17 (depends on 1) The method of claim 1, wherein the information defining the operational environment comprises an indication that the wireless device is indoors, semi-indoors, or outdoors. ### Claim 18 (depends on 17) The method of claim 17, wherein obtaining the information defining the operational environment comprises receiving an identification of a location information source from the wireless device identifying a source used by the wireless device to determine a location of the wireless device and determining whether the wireless device is indoors, semi-indoors, or outdoors based on the identification of the location information source. ### Claim 19 (depends on 18) The method of claim 18, wherein the identification of the location information source identifies a global navigation satellite system, GNSS, source and wherein the wireless device is determined to be outdoors based on identification of the GNSS source. ### Claim 20 (depends on 18) The method of claim 18, wherein the identification of the location information source identifies a wireless local area network, WLAN, source and/or a Bluetooth, BT, source, and wherein the wireless device is determined to be indoors based on identification of the WLAN source and/or the BT source. ### Claim
