摘要: The present disclosure provides methods and devices that use the RIS phase shifting ability to provide many degrees of freedom to enable data to be overlaid on transmitted signals. The data overlay is done while the RIS is still beamforming the signal towards the receiver(s). The phase shifting capabilities of the RIS elements can provide amplitude, phase, frequency, and polarization manipulations. These manipulations can help enhance the communication and provide the ability to overlay information. The present application also provides new configuration signaling among devices in a communication network utilizing the RIS and configuration for the RIS.

摘要: At a first communication device in a wireless communication network, reference signaling is received from a second communication device in two or more beams with a same direction, and one or more values associated with a direction at which the first communication device received the reference signaling from the second communication device are determined. The one or more values are determined based on the received reference signaling. The direction has a higher accuracy than a beam width associated with the received reference signaling. The direction may be or include an angle of arrival or an angle of departure, for example, and in the case of an angle of departure signaling indicative of the one or more values is transmitted by the first communication device, to the second communication device or another component such as network equipment.

摘要: Aspects of the present disclosure take advantage of a prism-like effect that occurs in a Reconfigurable Intelligent Surface (RIS), where the RIS reflects incident signals of different frequencies in different directions. for determining characteristics of a channel between a transmitter and a receiver wherein the channel includes the RIS. In particular, this may include estimating an angle of arrival (AoA) to the RIS in uplink transmission or the angle of departure (AoD) from the RIS in downlink transmission. Aspects of the present disclosure also provide solutions to compensate the prism effect for wideband transmission, especially at high frequencies (e.g. mmWave and THz).

摘要: Aspect of the present disclosure provide a device that includes an array of subarrays (AoSA) comprising a plurality of subarrays, each subarray including a plurality of antenna elements and a reconfigurable intelligent surface (RIS) that includes a plurality of configurable elements. The AoSA and the RIS are spaced apart from one another such that each subarray and a corresponding subset of the plurality of configurable elements are in each other's near field. Some embodiments described in the disclosure allow large spacing between antenna elements of the AoSA, thereby enabling lower complexity in circuit implementation for power amplification and phase shifting that may be associated with each antenna element, especially as high frequencies where spacing between antenna elements decreases and in some embodiments, reduces the number of antennas that are used.

摘要: Aspects of the present disclosure provide signalling that enables adaptively selecting a transmission scheme for different scenarios. Examples of the transmission schemes that may be selected from include beamforming, a channel modulation transmission scheme, (such as media-based modulation (MBM) or spatial modulation (SM)) or a hybrid of those two transmission schemes. The methods provided herein may apply to uplink, downlink, sidelink or backhaul scenarios.

摘要: Antenna beam sweeping according to the present disclosure involves different communication devices that are within an interference range of each other transmitting beam sweeping signals using different communication resources. This allows a receiver to distinguish between beam sweeping signals that are received from different transmitters, and may facilitate antenna beam alignment in multi-connection scenarios. Beam indices could be used to identify antenna beams for antenna beam management, in control signaling between base stations and User Equipment (UE), for example. Beam tracking and other aspects of antenna beam management are also disclosed.

摘要: A master user equipment (UE) device may coordinate device-to-device (D2D) communications amongst a plurality of UE devices. For example, a UE device, which has been designated as a master UE device, may coordinate a D2D communication between a first UE device and a second UE device. The master UE device may be a UE device that obtains an indication that it is a master UE device that is to coordinate D2D communications amongst the plurality of UE devices. In some embodiments, the coordinating the D2D communication may be on behalf of a network and/or to facilitate wireless communication between the network and at least one of the plurality of UE devices.

摘要: Aspects of the present disclosure relate to integration of sensing and wireless communications. Wireless communication networks can configure and implement both sensing signals and communication signals. Sensing signals, or sensing reference signals, can be used to determine properties of the environment, and do not carry any information or data for the purpose of communications. Communication signals, on the other hand, are signals that carry information or data between network entities. Sensing agents can be used for both passive and active sensing. Sensing agents may be dedicated devices capable of performing passive sensing, active sensing, or both. Sensing agents can also be existing networks device such as user equipment or transmit receive points. Methodologies described here may be particularly beneficial for half-duplex systems, but could also be implemented in full duplex systems.
