  • Patent number: 11071048
    Abstract: A radio device receives an access information table from the cellular network. The access information table comprises parameters of a plurality of configurations for controlling access of the radio device to the cellular network. Further, the radio device receives an identifier from the cellular network. Depending on the identifier, the radio device selects one of the configurations from the access information table. In response to determining that at least one of the received access information table and the received identifier is outdated, the radio device determines, depending on an indicator associated with the selected configuration, whether to perform an access attempt to the cellular network on the basis of the selected configuration.

  • Patent number: 11057091
    Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify a channel condition change (e.g., a beam switch, a bandwidth part (BWP) switch) for a channel between the base station and a user equipment (UE). The base station may transmit a downlink control information (DCI) that indicates the identified channel condition change and a resource allocation for transmissions between the base station and the UE. The base station may select a pattern of time and frequency resources for a channel state information reference signal (CSI-RS) for tracking for the UE, and transmit the CSI-RS using the identified pattern. The UE may identify the pattern based on the received DCI, and receive the CSI-RS using the identified pattern of time and frequency resources.

  • Patent number: 11006409
    Abstract: Methods, systems, and devices for wireless communication are described that provide for reduced timing between certain downlink communications and responsive uplink communications relative to certain legacy systems (e.g., legacy LTE systems). A user equipment (UE) or base station may be capable of operating using two or more timing configurations that each include an associated time period between receipt of a downlink communication (e.g., a grant of uplink resources or shared channel data) and a responsive uplink communication (e.g., an uplink transmission using the granted uplink resources or feedback of successful reception of the shared channel data). In cases where a UE or base station are capable of two or more timing configurations, a timing configuration for a transmission may be determined and the responsive uplink communication transmitted according to the determined timing configuration.

  • Patent number: 10952236
    Abstract: During a first P3 sweep that is associated with a first TCI state and during a second P3 sweep that is associated with a second TCI state, the UE stores the RSRP for each UE RX beam for each UE panel. Then, when the UE is scheduled for a downlink transmission through a DCI pointing to two these two TCI states, instead of only selecting the UE RX beam for respective panel based on the highest RSRP, the UE also takes the hypothetical inter-stream interference in to account when selecting the UE RX beams.
