Abstract: 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.

Abstract: Aspects are provided allowing UEs with non-coherent or partially coherent antennas to re-interpret TPMI received in DCI into a set of TPMIs corresponding to different subbands. The UE receives a TPMI associated with at least one first antenna and at least one second antenna which are non-coherent with each other, and the UE determines a set of TPMIs including a first and second TPMI based on the received TPMI. The set of TPMIs include at least one TPMI different from the received TPMI. The UE transmits, based on the first TPMI, from the at least one first antenna within at least one first subband. The UE also transmits, based on the second TPMI, from the at least one second antenna within at least one second subband different from the at least one first subband. Thus, full power transmission based on re-interpreted TPMI with reduced DCI overhead may result.

Abstract: Upon detection of a failure of a communication link between a remote management system and a communication node, a bypass link is established. The remote management system evaluates whether additional communication nodes can act as a bypass for management communications between the remote management system and the communication node whose management communication link has failed. The remote management system instructs a selected bypass communication node to establish the bypass management communication link between the bypass node and the disconnected node whose management communication link has failed. Depending on the relationship between nodes, management communications sent using the bypass link may be secured. The bypass link in some implementations may include multiple bypass communication nodes linked together to provide a chain of bypass management communication links between the remote management system and the disconnected communication node.
