  • Patent number: 11224034
    Abstract: A base station may access a channel following a successful channel access procedure. The base station may transmit an indication of a resource allocation to a user equipment (UE). The resource allocation may include an allocation of resources for subsequent communications between the base station and the UE, for example, defining a set of transmission time intervals (TTIs) during which the UE may transmit repetitions of uplink control information. The UE may also perform a channel access procedure to access the channel. The UE may transmit repetitions of the uplink control information using the set of TTIs according to the resource configuration. In some cases, the UE may stop transmitting uplink control information repetitions after a maximum number repetitions also according to the resource configuration. The base station may then receive and combine the uplink control information.

  • Patent number: 11159269
    Abstract: A method of acquiring Channel State Information (CSI) includes transmitting, from a Transmission and Reception Point (TRP) to a User Equipment (UE), information indicating that both of a Resource setting and a CSI reporting setting are commonly set to activation or deactivation. The Resource setting being set to the activation causes the UE to assume that CSI-Reference Signals (RSs) are to be transmitted from the TRP. The CSI reporting setting being set to the activation triggers the UE to perform CSI reporting. The method further includes receiving, with the UE, the CSI-RSs transmitted in accordance with a predetermined type of time domain behavior when the Resource setting is set to the activation. The method further includes performing, with the UE, the CSI reporting in accordance with the predetermined type of time domain behavior when the CSI reporting setting is set to activation.
