  • Patent number: 11159969
    Abstract: A wireless terminal receives signaling information, pertaining to a reference signal transmission in at least one specifically designated sub frame, the signaling information including a list, the list including base station identities. The terminal determines, from at least one of the base station identities in the list, the time-frequency resources associated with a reference signal transmission intended for observed time difference of arrival (OTDOA) measurements from a transmitting base station associated with said one base station identity. The time of arrival of a transmission from the transmitting base station, relative to reference timing, is measured. The wireless terminal can receive a command from a serving cell to start performing inter-frequency OTDOA measurement on a frequency layer containing reference signals, the frequency layer distinct from the serving frequency layer, the serving frequency layer not containing positioning reference signals.

  • Patent number: 11128399
    Abstract: A receiver processes a data signal and provides an acknowledgement within a turnaround time through use of code block alignment, reduced complexity or increased processing time. In a first embodiment, a radio access network (RAN) node enables encoded information to be segmented into multiple code blocks and maps a group of code blocks to be aligned with orthogonal frequency division multiplexing (OFDM) symbol boundaries such that efficient receiver processing can implement processing pipelining. In a second embodiment, the transmitter can provide more time or reduce the complexity of the packet, such as by repetition of bits of code blocks of the encoded information or by reserving resource elements (REs) such that the receiver has effectively more time (or less complexity) to process the last or last few code blocks of the packet.

  • Publication number: 20210185625
    Abstract: Embodiments of a User Equipment (UE), Generation Node-B (gNB) and methods of communication are disclosed herein. The UE may attempt to decode sidelink synchronization signals (SLSSs) received on component carriers (CCs) of a carrier aggregation. In one configuration, synchronization resources for SLSS transmissions may be aligned across the CCs at subframe boundaries in time, restricted to a portion of the CCs, and restricted to a same sub-frame. The UE may, for multiple CCs, determine a priority level for the CC based on indicators in the SLSSs received on the CC. The UE may select, from the CCs on which one or more SLSSs are decoded, the CC for which the determined priority level is highest. The UE may determine a reference timing for sidelink communication based on the one or more SLSSs received on the selected CC.
