During an uplink TDD slot, an UL UE transmits an UL signal that occupies a slot frequency range. Similarly, during a DL TDD slot, a DL UE receives a DL signal that occupies the slot frequency range. But during an SBFD slot, a UL UE transmits a UL signal that occupies only a first sub-band of the slot frequency range. Similarly, a DL UE receives a DL signal during an SBFD slot that occupies only a second sub-band of the slot frequency range. The second sub-band is distinct from the first sub-band. The DL UE may thus mitigate UE-to-UE interference during an SBFD slot by filtering the DL signal to substantially block the second sub-band from being received at the DL UE. |

Removing access to blockchain data
Access to blockchain data may be removed by deleting an encryption key held in a remote server. Incoming data is stored in the blockchain after being encrypted at the key server. An ordinary blockchain user gains access to the data, after forwarding the encrypted data to the remote key server for decryption. Upon receipt of an input (e.g., time stamp), the key server deletes the key. Thereafter, the encrypted data on the blockchain is rendered inaccessible to the ordinary blockchain data user. At no point, does the ordinary data user have access to the key stored in the remote server. Embodiments may find particular use in removing access to personal data stored in a blockchain following the elapse of a predetermined amount of time, as may be required by privacy laws. Granular control over data access can may be afforded through the use of composite keys and/or key hierarchies. |

Authentication of networked devices having low computational capacity
Authentication of a networked device with limited computational resources for secure communications over a network. Authentication of the device begins with the supplicant node transmitting a signed digital certificate with its authentication credentials to a proxy node. Upon verifying the certificate, the proxy node then authenticates the supplicant's credentials with an authentication server accessible over the network, acting as a proxy for the supplicant node. Typically, this verification includes decryption according to a public/private key scheme. Upon successful authentication, the authentication server creates a session key for the supplicant node and communicates it to the proxy node. The proxy node encrypts the session key with a symmetric key, and transmits the encrypted session key to the supplicant node which, after decryption, uses the session key for secure communications. In some embodiments, the authentication server encrypts the session key with the symmetric key. |

Methods, systems, and devices for wireless communications are described.
