  • Publication number: 20220248277
    Abstract: Aspects of the present disclosure relate to apparatuses, methods, and systems for performing early measurements during inter-RAT reselection. During cell reselection, a user equipment (UE) switches from a first cell using a first radio access technology (RAT) to a second cell using a second RAT that is different from the first RAT. The UE receives a measurement configuration from the first cell, and the measurement configuration configures the UE to perform early measurements for at least one RAT. After reselecting to the second cell, the UE determines whether to continue the early measurements based on the measurement configuration.

  • Patent number: 11405859
    Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for operating a user equipment (UE) in a next generation (NG) radio access network (RAN) (NG-RAN) to validate a system information block (SIB) for non-public networks (NPNs). In one aspect, a UE receiving a SIB-one (SIB1) from a cell of the NG-RAN may determine whether the cell supports non-public networks (NPNs) based on the received SIB1. If so case, the UE may determine whether an NPN-identifier (NPN-ID) in the received SIB1 matches an NPN-ID of a SIB stored in memory. If so, the UE may validate the stored SIB based at least in part on the received SIB1. If not, the UE may invalidate the stored SIB and obtain a new SIB per standard procedures.

  • Patent number: 11363493
    Abstract: Methods, systems, and devices for wireless communications are described. A base station may configure a secondary component carrier (CC) for a user equipment (UE) which is not aligned on a valid channel raster entry. The location of the secondary CC may be indicated based on a reference location relative to another frequency or another CC. The reference location of the secondary CC may be the center of the new CC, an edge of the secondary CC, the position of a subcarrier within the secondary CC, or the position of a resource. In some examples, the reference location of the secondary CC may be indicated relative a currently used CC, an arbitrary channel entry, or an absolute frequency location. In some examples, the relative location may be provided in resource blocks or subcarriers and the subcarrier spacing (SCS). The base station may indicate the width of the secondary CC to the UE.

  • Publication number: 20220085874
    Abstract: A user equipment (UE) selects or reselects a target cell of a non-terrestrial network or resumes connectivity with the target cell after a satellite handover for a permanently fixed low Earth orbit (LEO) cell. The target cell is a serving or non-serving cell. The UE determines a cell type of the target cell. The cell type may be a LEO cell type, a geostationary Earth orbit (GEO) cell type, a moving cell type, a fixed cell type, a temporarily fixed LEO cell type, or a permanently fixed LEO cell type. The UE completes selection or reselection of the target cell or completes the connectivity with the target cell, based on the cell type.

  • Patent number: 11265833
    Abstract: Certain aspects of the present disclosure relate to reporting difference in timing between cells using multiple connectivity in a wireless network. A first connection served by at least a first cell and a second connection served by at least a second cell to facilitate communicating with at least the first cell and at least the second cell are established. A reporting configuration specifying one or more parameters related to reporting a timing difference between cells is received. A timing difference between at least the first cell and at least the second cell is determined, and the timing difference is reported to at least the first cell over the first connection or to at least the second cell over the second connection. This can facilitate scheduling time aligned operations over the first and second cells, or related cell groups, in multiple connectivity.

  • Patent number: 11197251
    Abstract: As wireless communication technology advances, the bandwidth usage of wireless communications systems becomes increasingly flexible. For example, different user equipment (UEs) may support different bandwidths or radio frequency capabilities. However, a scheduling entity may not know wireless capabilities or characteristics (e.g., supported bandwidths, RF chain configurations, reconfiguration times, and/or the like) of the UEs for which the scheduling entity is to manage communications, which may hamper the ability of the scheduling entity to take advantage of the advances in flexible bandwidth usage described above. Techniques for synchronization, scheduling, bandwidth allocation, and reference signal transmission in a wireless communications system associated with flexible bandwidth allocation, such as a 5G network, are described herein.

  • Publication number: 20210376876
    Abstract: Coverage enhancements and coverage mode switching related optimizations are discussed for user equipments (UEs) that may switch between various coverage extension (CE) and non-CE modes of operation. In such enhancements, paging uncertainty and delays may be reduced by sending pages either simultaneously or using historical information over multiple coverage modes available to UEs. Random access procedures may be improved by providing CE mode random access procedures that are available when normal mode random access attempts fail and before declaring radio link failure. Additional aspects include improvements for more advanced UEs to improve coverage within normal mode operations by leveraging techniques used for narrowband CE mode operations, including transmission repetition and gapless transmission scheduling over hopped narrowband frequencies.
