  • Patent number: 11153833
    Abstract: Systems and methods are disclosed for adjusting Radio Link Monitoring (RLM), Radio Link Failure (RLF) detection, RLF recovery, and/or connection establishment failure detection for wireless devices (16) in a cellular communications network (10) depending on mode of operation. In one embodiment, a node (14, 16) in the cellular communications network (10) determines whether a wireless device (16) (e.g., a Machine Type Communication (MTC) device) is to operate in a long range extension mode of operation or a normal mode of operation. The node (14, 16) then applies different values for at least one parameter depending on whether the wireless device (16) is to operate in the long range extension mode or the normal mode. The at least one parameter includes one or more RLM parameters, one or more RLF detection parameters, and/or one or more RLF recovery parameters.

  • Publication number: 20210120573
    Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for reporting content processing times to a base station to allow the base station to efficiently schedule bi-directional communications one or more UEs. A content processing time may correspond to the time taken by a UE to process one or more downlink signals received in one or more downlink transmissions. In some examples, the UE may report a content processing time for each downlink transmission. In some examples, the UE may report one or more content processing times for multiple downlink transmissions. The base station may use the content processing times to configure an appropriate gap between downlink and uplink transmissions such that the UE may have sufficient time to process downlink signals before transmitting one or more uplink transmissions in response to the one or more downlink transmissions.

  • Publication number: 20210105752
    Abstract: Aspects are provided which allow a base station to dynamically select or indicate an active CORESET associated with a search space or set of PDCCH candidates. The base station selects, for at least one UE, an active CORESET associated with a search space for a period of time. The base station transmits a dynamic indication of the active CORESET associated with the search space to the at least one UE. A UE receives the dynamic indication of the active CORESET associated with the search space for the period of time. The UE then monitors for a downlink control channel during the period of time based on the dynamic indication of the active CORESET.

  • Publication number: 20210029704
    Abstract: Methods, systems, and devices for wireless communications are described. A base station may switch semi-persistently scheduled (SPS) or configured grant (CG) transmissions for a user equipment (UE) across component carriers according to a resource switching pattern to avoid resource conflict with control information on one or more component carriers. The resource switching pattern may have multiple flows spanning different component over a time interval for redundancy. According to some aspects, a base station may transmit a synchronization signal block (SSB) in one of a set of flexible SSB locations or candidate SSB locations, where each of the set of candidate SSB locations is associated with a respective SSB identifier.

    Abstract: Methods, systems, and devices for wireless communications are described. Interference between random access channel (RACH) transmissions and Industrial Internet of Things (IIoT) transmissions may be avoided with a RACH occasion forbidden mask and a dynamic indication of availability of downlink retransmission resources. A user equipment (UE) may receive an indication of a RACH configuration and a forbidden mask associated with the RACH configuration. The UE may identify, from a set of random access occasions indicated by the RACH configuration, a subset of allowed random access occasions based on the forbidden mask. The UE may transmit a random access message during at least one allowed random access occasion of the subset. Additionally or alternatively, a base station may determine whether one or more transmissions on a component carrier (CC) were successful, and transmit downlink control information (DCI) indicating whether a set of random access occasions are available on the CC.
