Modern telecommunications systems include heterogeneous mixtures of second, third, and fourth generation (2G, 3G, and 4G) cellular-wireless access technologies, which can be cross-compatible and can operate collectively to provide data communication services. Global Systems for Mobile (GSM) is an example of 2G telecommunications technologies; Universal Mobile Telecommunications System (UMTS) is an example of 3G telecommunications technologies; and Long Term Evolution (LTE), including LTE Advanced, and Evolved High-Speed Packet Access (HSPA+) are examples of 4G telecommunications technologies. As increased capabilities of user equipment (UE) enable greater data consumption, placing increased demands on networks, new networks with higher capabilities have been developed. The 5G telecommunications technologies are the next generation mobile networks that are designed to combine both an evolution and revolution of the existing LTE/LTE-A mobile networks to provide a much higher connectivity, greater throughput, much lower latency, and ultra-high reliability to support new use cases and applications.
The 5G telecommunications technologies utilize the existing LTE frequency band (600 MHz to 6 GHz) and millimeter wave bands (24-86 GHz) and aim to provide higher data rates and low latency. However, as a higher frequency is used, such as the millimeter band, the path loss associated with the higher frequency signal increases, leading to a shorter coverage for a given power, and the directionality of the signal becomes narrower, requiring a point-to-point communication. Compared to the existing telecommunication standards (2G, 3G, and 4G/LTE), the 5G millimeter wave telecommunication is more susceptible to the environment, for example, the surrounding of a user equipment (UE), which may quickly change, for example, from an open field to a street surrounded by tall buildings in a moving vehicle.
The detailed description is set forth with reference to the accompanying figures. In the figures, the left-most digit(s) of a reference number identifies the figure in which the reference number first appears. The use of the same reference numbers in different figures indicates similar or identical items or features.
The methods, devices, and computer readable media discussed herein are directed to a fifth generation (5G) cellular-wireless access technology communication device, and more specifically, to improving a communication performance under a certain environment using a supplemental communication device.
The 5G telecommunications technologies utilize millimeter wave bands (24-86 GHz) for improving data rates and latency performance. However, a communication using a high frequency, such as the millimeter band, experiences a higher path loss and more directivity and compared to the existing telecommunication bands (e.g., non-millimeter bands associated with 2G, 3G, and 4G/LTE), requiring substantially a line-of-sight or a point-to-point communication with a target user equipment UE. Thus, in some cases, the 5G telecommunication is more susceptible to changes in the surrounding environment of the UE, for example, an open field compared to a city street surrounded by tall buildings.
As the UE experiences a degradation of a signal quality in a communication with a base station, such as a millimeter wave band communication with a 5G base station, a supplemental communication device may be launched to improve the signal quality of the communication with the base station. Upon detecting that the signal quality has fallen below a preselected threshold, the supplemental communication device may be launched from a platform associated with the UE, such as a vehicle of a user of the UE where the UE is currently located, to establish an improved communication with the base station that is closer to a point-to-point communication while maintaining a communication with the UE. As the location of the UE changes, for example the UE and the user of the UE in a moving vehicle, the supplemental communication device may track the movement of the UE and maintain the point-to-point communication with base station by directionally orienting its antenna(s) towards the base station and the communication with the UE. The supplemental communication device may also monitor and/or detect its surroundings and adjust its flight path to avoid physical obstructions.
Additionally, the supplemental communication device may be able to help extend a coverage area as the UE in the vehicle moves away from the coverage area by positioning the supplemental communication device in a more ideal position in the air than the vehicle position regardless of the cellular communication technologies or bands used.
A UE 102 and a user (not shown) may be located in a moving vehicle 104, which may be traversing through a relatively open field of a residential area 106 with low buildings 108. In this environment, a communication path between a base station 110 and the vehicle 104 may be relatively free of obstructions and the base station 110 may be able to establish a point-to-point communication 112 with the UE 102 in the vehicle 104. However, as the vehicle 104 moves, as indicated by an arrow 114, and enters a city area 116, an intended point-to-point communication path 118 between the base station 110 and the UE 102 in the vehicle 104 may be obstructed with tall buildings 120, and the intended point-to-point communication 118 may be blocked at a point 122 by the tall buildings 120.
Because the direct point-to-point communication path 118 with the base station 110 is blocked for the UE 102, thereby making the UE 102 unable to establish a communication with the base station 110, a supplemental communication device 202, including a flight control component, may be launched from the vehicle 104 to establish a point-to-point communication 204 with the base station 110. The supplemental communication device 202 may also establish a communication with the UE 102, thereby enabling the UE 102 to establish communication via the supplemental communication device 202 with the base station 110. The flight control component of the supplemental communication device 202 may include a propulsion component comprising one or more power sources, motors, propellers, control and navigation systems, etc., and launch itself from a platform on the vehicle 104. As the UE 102 moves with the vehicle 104, the supplemental communication device 202 may move along or follow the vehicle 104 based on information from the flight control component to maintain the communication between the UE 102 and the base station 110. While at the platform, the supplemental communication device 202 may recharge its power sources for the flight control component and communication components.
As the vehicle 104 moves from a location A to a location B, the supplemental communication device 202 may follow the vehicle 104 to maintain the communication 206 with the UE 102. However, as the supplemental communication device 202 follows the movement of the vehicle 104, the location of the supplemental communication device 202 relative to the base station 110 changes from the location A to B, and the point-to-point communication between the base station 110 and the supplemental communication device 202 may degrade or be lost. To maintain the point-to-point communication with the base station 110, the supplemental communication device 202 may monitor a quality of the communication with the base station 110 and aim an antenna 302 towards the base station 110 to maintain the quality above a preselected threshold for a point-to-point communication 304. The quality of the communication monitored may include a quality of a signal from the base station 110 received by the supplemental communication device 202 such as a signal strength of the signal (e.g., received signal strength indicator (RSSI), reference signal received power (RSRP), etc.), a bit error rate of the signal, a frame error rate of the signal, a signal-to-noise ratio (SNR), and the like.
Although the antenna 302 is shown as a single antenna and the supplemental communication device 202 is oriented to aim the antenna 302 towards the base station, the antenna 302 may include a single antenna configured to be directionally oriented towards the base station 110, a plurality of sectorized antennas each of which having a corresponding sector for communicating with the base station 110, and an antenna array configured to directionally beam-form towards the base station 110 for communicating with the base station 110.
The supplemental communication device 202 may detect its surrounding. For example, the supplemental communication device 202 may detect the surroundings with sensor(s), such as one or more cameras, radar sensors, lidar sensors, sonar sensors, and the like, and provide visual data of its surroundings to the UE 102. A camera 306 is illustrated in
At block 402, the supplemental communication device 202 may pair with the UE 102 and establish a first communication, such as the communication 206, with the UE 102 at block 404. The first communication 206 between the supplemental communication device 202 with the UE 102 may be accomplished using wireless communication or a communication cable. The supplemental communication device 202 may establish a second communication, such as the communication 304, with the base station 110 at block 406, and enable the UE 102 to communicate with the base station 110 using the first and second communications 206 and 304 at block 408. At block 410, the supplemental communication device 202 may monitor the signal quality of a signal, such as the communication 304 received from the base station 110, and may maintain the signal quality above a threshold by aiming one or more antennas 302 of the supplemental communication device 202 at block 412. Upon detecting that the signal quality has fallen within a preselected range of the threshold or below the threshold, the supplemental communication device 202 may be launched from a landing platform at block 414 and the supplemental communication device 202 may maintain an airborne state proximate to the UE 102 at block 416.
The signal quality monitored at block 410 may include a signal strength of the signal (e.g., received signal strength indicator (RSSI), reference signal received power (RSRP), etc.) of the communication 304, a bit error rate of the signal, a frame error rate of the signal, a signal-to-noise ratio (SNR), and the like, received by the supplemental communication device 202. To maintain the signal quality above the threshold at block 412, the supplemental communication device 202 may directionally orienting the one or more antennas towards the base station 110, utilizing one of a plurality of sectorized antennas, each of the plurality of sectorized antennas having a corresponding sector and configured to maintain the signal quality above the threshold within the corresponding sector, or directionally beam-forming an antenna array towards the base station 110. However, if the supplemental communication device 202 is unable to maintain the signal quality above the threshold, the supplemental communication device 202 may notify the UE 102 and return to the platform of the vehicle 104. For example, once the signal quality falls below the threshold, the supplemental communication device 202 may stay airborne and continue attempting to maintain the communication with the base station 110 for a preselected time period, and if the signal quality does not reach above the threshold after the preselected time period, the supplemental communication device 202 may return to the platform.
At block 418, the supplemental communication device 202 may provide visual data of its surroundings and detect the surroundings based at least in part on the visual data. As described above with reference to
The supplemental communication device 202 may comprise a first transceiver 502, a second transceiver 504 coupled to the first transceiver 502, a flight control component 506. The first transceiver 502 may be configured to pair with the UE 102 and establish a communication 508 with the UE 102. Although the communication 508 is shown as a wireless communication, the first transceiver 502 may also establish the communication 508 with the UE 102 using a communication cable (not shown). The second transceiver 504 may be configured to communicate 510 with the base station 110, and together with the first transceiver 502, may enable the UE 102 to communicate with the base station 110. The flight control component 506 may be configured to maintain the supplemental communication device 202 in an airborne state proximate to the UE 102.
The second transceiver 504 may further include an antenna system 512 configured to aim one or more antennas, such as the antenna 302, of the antenna system 512 for communicating 510 with the base station 110 and maintaining a signal quality of the communication 510 with the base station 110 above a threshold. The signal quality the communication 510 may include a signal strength of a signal of the communication 510, a bit error rate of the signal, or a frame error rate of the signal, received by the second transceiver 504.

The flight control component 506 may further comprise a propulsion component 518 comprising one or more power sources, motors, propellers, control and navigation systems, etc., may be configured to propel the supplemental communication device 202 including launching the supplemental communication device 202 from a landing platform upon the signal quality falling within a preselected range of the threshold, adjusting a flight path based at least in part on the surroundings, and maintaining the supplemental communication device 202 within a predetermined proximity of the UE 102 based on the surroundings, for example within 50 feet of the UE 102.
