Abstract: Aspects of the disclosure relate to radio access networks with a capability to dynamically reconfigure a number of transmission-reception points (TRPs) in a single-frequency network (SFN) based on channel measurements. In one example, a mobile device receives a configuration message including a plurality of transmission configuration indicator (TCI) states, and potentially further including an indication identifying one or more of the TCI states as main TCI states. The message may further include an indication that it includes the plurality of TCI states. The UE receives a downlink traffic channel and demodulates the traffic channel based on only a subset of the TCI states (e.g., the main TCI state (s)). The UE further measures one or more channel parameters corresponding to each TCI state of the plurality of TCI states, and transmits a channel state information report based on the channel parameters. Other aspects, embodiments, and features are also claimed and described.

Abstract: A new channel is added to FLO networks that carries embedded signaling parameter information. The design is such that regardless of the actual values of the signaling parameters conveyed, a receiver will be able to demodulate this new channel. Moreover, the addition of the new channel does not render a FLO network that has been so configured to not be backwards-compatible with existing devices.

Abstract: A user equipment (UE) generates a positioning state information (PSI) report that is transmitted in a lower layer channel container, e.g., in the Physical channel or Medium Access Control channel, to a network entity to reduce latency. For example, the PSI report is generated based on a plurality of PSI report elements determined from uplink (UL), downlink (DL) or UL and DL positioning measurements. Each PSI report element includes information related to positioning measurements performed by the UE. The PSI report elements are ordered, e.g., from highest priority to lowest priority, according to priority based rules. If the size of the PSI report elements is larger than the lower layer channel container, one or more of the low priority PSI report elements are omitted from the PSI report. A network entity may receive and process the PSI report based on the same priority based rules.

Abstract: The present disclosure describes methods and apparatuses for improved transport block decoding in devices capable of wireless communication, which may include user equipment and network entities. For example, the present disclosure presents methods and apparatuses for decoding a code block from a plurality of code blocks corresponding to a transport block, obtaining a reliability indicator that identifies a reliability of the decoding of the code block, comparing the reliability indicator to a reliability threshold, and determining whether to decode a subsequent code block from the plurality of code blocks based on the comparing. Furthermore, these methods and apparatuses may include determining not to decode at least one subsequent code block of the transport block where the comparing indicates that the reliability indicator is less than the reliability threshold. As such, device power is not unnecessarily consumed by decoding likely superfluous code blocks.
