  • Patent number: 11589403
    Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently performing dynamic power control with minimal complexity in a dual connectivity mode. In particular, a user equipment (UE) may determine the reserved power (or maximum available power) for uplink transmissions on one or more cells in one cell group to a base station based on the total power available to the UE and the minimum reserved power for uplink transmissions on one or more cells in another cell group. Once the UE determines the reserved power for conflicting uplink transmissions on one or more cells in a cell group, the UE may allocate the reserved power to each uplink transmission on the one or more cells in the cell group (e.g., based on a priority of each of the uplink transmissions).

  • Publication number: 20230051054
    Abstract: Satellites in a non-terrestrial network may provide positioning reference signals (PRS) to user equipment (UE), with which the UE may determine its position using propagation delay difference measurements, such as Time Difference of Arrival (TDOA) measurement. Due to the large distances between satellites and the UE, the propagation delay differences in the PRS received from satellites may exceed half a radio frame, resulting in a frame level timing ambiguity in the differential measurements. The satellites transmit secondary PRS, along with primary PRS, that include timing information to resolve frame level timing ambiguity of the primary PRS. The positioning occasions in the secondary PRS, for example, may be aligned with corresponding positioning occasions primary PRS within each radio frame, and are transmitted with a periodicity that is an integer multiple (greater than 1) of that of the primary PRS to resolve the frame level timing ambiguity of the primary PRS.

  • Patent number: 11582690
    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.

  • Publication number: 20230029863
    Abstract: Methods, systems, and devices for wireless communications are described that provide for signaling and switching of beam pair links (BPLs) for directional transmission beams between a base station and a user equipment (UE). A threshold value may be determined, which corresponds to an amount of time for a UE to receive and decode control information, and apply a different BPL than a current BPL that that is in use. The UE may maintain a BPL for data, which is used during data transmission time intervals (TTIs) until an indication is received to change the BPL for data. The UE and the base station may determine to change between BPLs based at least in part on the threshold value and a scheduling offset between a control channel transmission that allocates resources for a data TTI and a start of the data TTI.

  • Publication number: 20230023056
    Abstract: Disclosed are techniques for positioning. A receiver measures a time of arrival (ToA) of a positioning reference signal (PRS) transmission of a first PRS sequence transmitted by a first transmitter, measures a ToA of a PRS transmission of a second PRS sequence transmitted by a second transmitter, and determines an observed time difference of arrival (OTDOA) as a difference between the ToA of the PRS transmission of the first PRS sequence and the ToA of the PRS transmission of the second PRS sequence, wherein the OTDOA is less than half a maximum differential delay expected between the PRS transmission of the first PRS sequence and the PRS transmission of the second PRS sequence, and wherein a repetition duration of the first PRS sequence and the second PRS sequence is greater than 10 milliseconds (ms) and at least twice the maximum differential delay.

  • Publication number: 20230023214
    Abstract: Various aspects described herein relate to dynamically controlling a time when random access initiated in a target cell of a non-terrestrial network. For example, when a user equipment (UE) detects an event that triggers a random access procedure in the target cell, the UE may monitor a control channel from the target cell for a control signal during a target cell monitoring window prior to initiating random access in the target cell. For example, the control signal may include a dynamic indication to identify UEs allowed to initiate random access, whereby a UE is not permitted to autonomously start contention-based random access in the target cell during the target cell monitoring window unless the UE has received the control signal. In this way, the target cell may regulate a rate at which UEs initiate the RACH procedure in order to manage congestion in the target cell.

  • Patent number: 11546052
    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for managing beam configurations and parameters for non-terrestrial networks. In some implementations, a UE may detect a synchronization signal block (SSB) transmitted by a satellite via a first beam. Aspects of the present disclosure recognize that each beam may be identified by a unique SSB index based at least in part on a time or frequency on which the SSB is received. Thus, the SSB may be identified based on a frequency-domain SSB index or a time-domain SSB index. The UE may further determine one or more wireless communication parameters associated with the first beam. The UE may generate a mapping between the SSB and the wireless communication parameters associated with the first beam, and thereafter communicate with the satellite using the mapping.
