Telecommunications apparatus and methods
A wireless telecommunication system comprises a base station and a terminal device (UE). The UE is configured to determine its mobility status and an associated reliability, e.g. an indication of the extent to which the UE is moving and the confidence in this determination. In some cases the reliability may be based on how the UE determined its mobility status. For example, if the UE determined itself to be of relatively low mobility because it has an internal configuration setting indicating it is deployed in a fixed position, the reliability of this mobility status may be considered to be greater than if the UE determined itself to be of relatively low mobility because it has not recently undergone many base station handovers. The UE is configured to convey an indication of the mobility status and the reliability to the base station. The base station may then configure the UE for operation within the wireless telecommunications system in a manner that takes account of both the mobility status and the reliability for the mobility status. This can help optimise configuration settings for the UE which depend on device mobility. |

System and method for latency critical quality of service using continuous bandwidth control
A system and method are provided for a bandwidth manager for packetized data designed to arbitrate access between multiple, high bandwidth, ingress channels (sources) to one, lower bandwidth, egress channel (sink).

Each source is associated with a ranking that is recalculated every data word. When a source buffer sends enough words to have its absolute rank value increase above that of another source buffer waiting to send, the system “cuts” the current packet by forcing the sending buffer to stop mid-packet and selects a new, lower ranked, source buffer to send. When there are multiple requesting source buffers with the same rank, the system employs a weighted priority randomized scheduler for buffer selection. |

Compression and homomorphic encryption in secure query and analytics
Systems and methods for end-to-end encryption and compression are described herein. A query is encrypted at a client using a homomorphic encryption scheme. The encrypted query is sent to a server where the encrypted query is evaluated over target data to generate encrypted response without decrypting the encrypted query. The result elements of the encrypted response are grouped, co-located, and compressed, without decrypting the encrypted query or the encrypted response. The compressed encrypted response is sent to the client where it is decrypted and decompressed to obtain the results of the query without revealing the query or results to the owner of the target data, an observer, or an attacker. |

Receiver bandwidth adaptation
A receiver bandwidth adaptation for radio access technologies (RATs) may be for a New Radio (NR) or 5G flexible RAT. A WTRU control channel {e.g., receiver) bandwidth may change, for example, based on monitoring a downlink channel for an in indication using a bandwidth (BW) associated with a first BW configuration. The indication may include a signal to change the receiver BW. The WTRU may change the receiver BW associated with the first BW configuration to a second BW configuration when the WTRU receives the indication on a downlink (DL) channel. The WTRU may perform one or more measurements associated with the second BW configuration in response to the change of the receiver BW to the second BW configuration. The WTRU may transmit measurement information to a network entity. The WTRU may receive a DL transmission from the network using the second BW configuration. |
