摘要： Embodiments are provided to enable distributed open-loop multi-user co-operative multi-point (MU-CoMP) scheduling and transmission. In an embodiment, network nodes schedule data transmissions for UEs among multiple transmission tiers that include a first transmission tier having predetermined modulation and coding and a second transmission tier having adaptive modulation and coding. The first transmission tier and the second transmission tier are in respective time-frequency resources that at least partially overlap. The network nodes transmit the scheduled data transmissions in the transmission tiers according to the scheduling for the UEs. A UE receives CoMP transmissions once it is scheduled for transmission by multiple network nodes.

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： 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.

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： Methods and apparatus are provided that may simplify and enhance the location of nodes in a network, including ED and mobile TPs, even if all or many of the nodes are mobile. The methods may be used to enable single TP positioning, and may be used to reduce synchronization error. The provided methods make use of smart reflectors having known location. By processing a combination of signals, which may include an original transmitted signal, and/or one or more reflected signals, the location of a receiving node can be determined. Media tagging may be employed to allow a receiver to detect the identity of the nearby reflectors (with known locations) and based on the identity determine the locations of the reflectors. Using this information, the receiving node can detect its location regardless of knowing the transmission source and/or location.

摘要： At a first User Equipment (UE) in a wireless communication network, signaling that is associated with a direct wireless communication link between the first UE and a second UE is received. Signaling indicative of an estimate of range between the first UE and the second UE, based on the received signaling, is transmitted to network equipment in the wireless communication network. According to another aspect of the present disclosure, signaling that is indicative of an estimate of range associated with such a direct wireless communication link is received, and signaling indicative of a prediction model and/or signaling indicative of a prediction from the prediction model is transmitted. The prediction model is for prediction of Line of Sight (LoS) status of communication links in the wireless communication network, and is based in part on the estimate of range.

摘要： Network equipment receives, from User Equipment (UE), information indicative of each of multiple UE locations in a wireless communication network. For each location, a respective antenna beam direction for communications between the network equipment and a UE at each location is determined. A Machine Learning (ML) module is trained using each location as an ML module input and the respective antenna beam direction for each location as an ML module output. The trained ML module is then used to provide beam predictions based on UE location. Based on the current location of a UE, one or more antenna beam directions for communications between the network equipment and the UE at the current location are obtained from the ML module. The UE location is input to the ML module, and the antenna beam direction(s) are then obtained from the ML module output(s).

摘要： Colliding random access channel messages from multiple User Equipment (UEs) attempting to access a communication system include common access information for the multiple UEs. Responses to the messages are transmitted. A response to one UE includes UE identifier information from the common access information and responses to other UEs include new UE identifier information for each other UE. In another embodiment, a random access channel message that is received from a UE includes a dedicated random access sequence that is dedicated for use by a particular UE within a coverage area of a communication system. A determination can be made as to whether the received random access channel is received from the particular UE based on any one or more of: a set of one or more access points at which, a direction from which, and a receiving antenna beam on which the received random access channel message is received.

摘要： Systems and methods for DFT-S-SCMA (discrete Fourier Transform-spread-sparse code multiple access) are provided. Input bits are encoded with an SCMA encoder. The output is precoded with a IDFT (inverse DFT) to produce a precoded SCMA block. Multiple precoded SCMA blocks are combined at the input of a DFT. This is done in parallel for multiple sets of SCMA blocks at multiple DFTs. Then, the outputs of the DFTs are combined and OFDM modulated. This approach can be used to improve the PAPR (peak to average power ratio) at the output of the OFDM modulation.
