  • Publication number: 20230198610
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling identifying a configuration of a set of uplink slots for the UE to transmit uplink reference signals to a satellite. The UE may transmit, to the satellite, a set of uplink reference signals on the set of uplink slots according to the configuration. The set of uplink reference signals may include sounding reference signals (SRSs), positioning references signals (PRSs), or both. In some implementations, the UE may transmit the set of uplink reference signals in accordance with one or more timing advance values, where the timing advance values are indicated to the satellite by the UE, pre-configured by the satellite, or both. The UE may then, from a network node, an indication of a position of the UE based on the set of uplink reference signals.

  • Patent number: 11677488
    Abstract: User equipment associated with a legacy network may utilize a bottom-to-top search technique to identify relevant control channel samples. Generating a control channel that is configured for the bottom-to-top search technique may lead to poor performance in a single-carrier waveform, which may be disadvantageous as networks move toward New Radio. In some aspects, described herein, a base station generates a control channel that is configured to minimize gaps in the control channel, and a user equipment performs a top-to-bottom search technique to identify relevant control channel samples. By using the top-to-bottom search technique, degradation of single-carrier waveforms is reduced and efficiency is improved.

  • Patent number: 11677509
    Abstract: Methods, systems, and devices for wireless communications are described in which a physical layer at a user equipment (UE) or a base station may generate feedback for one or more communications that are attempted to be received from a transmitting device. The physical layer feedback may be communicated to the transmitting device in higher layer communications, such as in a medium access control (MAC) layer control element (CE), where the MAC layer is a higher layer than the physical layer in a multi-layer protocol stack of the UE and base station. The physical layer feedback may be communicated after being triggered by one or more conditions at the UE or base station.

  • Publication number: 20230179977
    Abstract: Certain aspects of the present disclosure relate to methods and apparatus for pilot design for Narrow-Band Internet of Things (NB-IoT). In certain aspects, the method generally includes determining at least one binary code sequence to use as a demodulation reference signal (DMRS) for a channel transmitted across one or more subframes using one or more tones within a resource block (RB) allocated to the UE for narrowband communication, and transmitting the channel including the DMRS using the one or more tones and the determined binary code sequence. In certain aspects, the binary code sequence may be determined based on a binary random sequence, such as pseudo noise (PN) or Gold sequence.

  • Patent number: 11671932
    Abstract: Various aspects relate to adjusting communication timing in response to a switch from one feeder link to another feeder link in a non-terrestrial network. For example, when a satellite moves out of the coverage area of a first ground network entity (or if the first ground network entity is turned off), the satellite switches to a second ground network entity. The resulting switch from a first feeder link for the first ground network entity to a second feeder link for the second ground network entity may cause a timing glitch that adversely affects the UEs under the coverage of the satellite. The disclosure relates in some aspects to sending an indication of the switch and/or a common timing adjust command to all of the UEs affected by the feeder link switch.

  • Patent number: 11665745
    Abstract: Methods, systems, and devices for wireless communications are described in which random access preambles may be designed to provide for relatively low inter-carrier interference (ICI) of adjacent available frequency resources in a non-terrestrial network (NTN). Random access preambles for NTN random access requests may be selected from a first set of random access preambles that are different from a second set of random access preambles for terrestrial random access requests. The first set of random access preambles may be a subset of the second set of random access preambles. The first set of random access preambles may be provided for contention-based random access (CBRA) and contention-free random access (CFRA) preambles may be configured by a base station from random access preambles that correspond to or are different from the second set of random access preambles.

  • Patent number: 11659599
    Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may account for propagation delay when initiating a random access (RACH) procedure. For example, the UE may determine transmission timing for a RACH preamble based on an estimated propagation delay, such that the RACH preamble is received at a base station approximately at the beginning of a slot. To support reliable communication of the RACH preamble, the UE may implement a timing offset. In some examples, the base station may configure the UE with the timing offset using system information. Alternatively, the UE may be pre-configured with the timing offset. By determining the transmission timing for the RACH preamble further based on the timing offset, the UE may ensure that the RACH preamble is received at the base station after a slot boundary (e.g., avoiding causing interference to communications in a previous slot).

  • Patent number: 11658780
    Abstract: Methods, systems, and devices for wireless communications are described that support demodulation reference signal (DMRS) multiplexing scheme selection for uplink transmission. A user equipment (UE) may monitor for a parameter from a base station indicating which DMRS scheme to use. In some cases, the base station may transmit a radio resource control (RRC) parameter indicating a first DMRS scheme to the UE. The UE may select the first DMRS scheme based on receiving the RRC parameter from the base station or based on a default DMRS scheme. The UE may transmit a transmission based on the first DMRS scheme.

  • Publication number: 20230156589
    Abstract: Methods, systems, and devices for wireless communication are described. In one example, an aerial user equipment (UE) may receive an indication of a priority for cell selection for aerial UEs from each cell in a set of cells and may select a cell from the set of cells based on the priority of each cell in the set of cells. In another example, an aerial UE may connect to a network available to aerial UEs and non-aerial UEs for auxiliary communications, when appropriate. In yet another example, when an aerial UE transitions to a new mission status, the aerial UE may transmit a tracking area update (TAU) if the aerial UE is connected to a cell in a tracking area that does not support the new mission status. In yet another example, a base station may page an aerial UE based on a mission status of the aerial UE.

  • Patent number: 11653245
    Abstract: Methods, systems, and devices for wireless communications are described. In some networks, a user equipment (UE) may perform radio link monitoring according to one or more radio link monitoring configurations. The UE may select a radio link monitoring configuration from a first radio link monitoring configuration associated with radio link monitoring over a duration that a hybrid automatic repeat request (HARQ) process is enabled and a second radio link monitoring configuration associated with radio link monitoring over a duration that the HARQ process is disabled. The UE may monitor reference signals using the selected radio link monitoring configuration, and may determine a radio link failure, a beam failure, or both has occurred based on monitoring the one or more reference signals using the selected radio link monitoring configuration. The UE may subsequently transmit a measurement report based on determining the radio link failure, the beam failure, or both.
