Abstract: This disclosure relates to techniques for quickly recovering from radio link failure in a wireless communication system. A wireless device may establish a wireless link with a cell. The wireless device may detect radio link failure for the wireless link. The wireless device may attempt to re-establish the wireless link using a previously provided wireless link configuration. If the cell accepts the attempt re-establish the wireless link using the previously provided wireless link configuration, the wireless link may be re-established in accordance with the previously provided wireless link configuration.

Abstract: To accommodate a mix of high frequency carriers and lower frequency carriers, a protocol stack may include a radio link control (RLC) entity that allows configuration of status reporting control parameters on per carrier, or per subcarrier spacing. Alternatively, a protocol stack may include two RLC entities, one for handling high frequency carriers, and another for handling lower frequency carriers. High frequency carriers and lower frequency carriers may be distinguished based on a frequency threshold. Furthermore, a user equipment may transmit to the network an indication of its L2 buffer size. The network may configure the UE and/or control scheduling, to ensure the UE's L2 buffer does not overrun. Alternatively, the UE may indicate that it can support a percentage of a maximum buffer size. The network may configure the UE and/or control scheduling so that the UE's buffer occupancy does not exceed the percentage.

Abstract: The present application relates to devices and components including apparatus, systems, and methods to configure a UE for dual connectivity. In an example, a network node requests the UE to indicate the capability it supports for the dual connectivity. This request can implicitly or explicitly indicate that the UE should report carrier grouping information. In response, this information is sent by the UE, and the network node can configure an MCG and an SCG for the UE based on the reported carrier grouping information.

Abstract: Systems, methods, and devices are provided for performing cell selection or reselection in networks that include earth moving beams. In one example, a method includes receiving, via a satellite, control information transmitted by a base station indicating that a beam associated with a cell ID has been redirected; in response, measuring a beam strength of the redirected beam; and performing cell re-selection based on the measured beam strength.

IPC: H04W72/00
Abstract: This disclosure relates to techniques for supporting switching between point to point and point to multipoint delivery with service continuity for broadcast and multicast services in a wireless communication system. A cellular base station and a wireless device may establish a wireless link. The cellular base station may provide information configuring an over the air delivery type with which to receive a broadcast or multicast service, which may be received by the wireless device. The cellular base station may transmit the service using the configured delivery type, and the wireless device may correspondingly receive the service. The cellular base station may provide information configuring the wireless device to switch to a different over the air delivery type, with service continuity. The cellular base station may then transmit the service using that delivery type, and the wireless device may correspondingly receive the service.

Abstract: This disclosure relates to techniques for reducing latency in a high-propagation-delay wireless communication system. A user equipment device (UE) may transmit to a base station (BS) a first buffer status report (BSR) indicating an amount of uplink data buffered by the UE for transmission to the BS, and may subsequently transmit to the BS a first BSR update message indicating that an additional amount of uplink data has been buffered by the UE subsequent to transmission of the first BSR. The first BSR update message may be transmitted prior to expiration of a timer authorizing transmission of a second BSR following the first BSR. The UE may receive from the BS an uplink grant allocating resources for transmission of at least a portion of the uplink data buffered by the UE. The uplink grant may have a size based on the first BSR and the first BSR update message.

Abstract: A user equipment (UE) may operate on a dormant bandwidth part (BWP) and a non-dormant BWP of a carrier. The UE identifies a dormant bandwidth part (BWP) and a non-dormant BWP of a carrier corresponding to a primary secondary cell (PSCell) of a secondary cell group (SCG) for dual connectivity (DC), determines that the dormant BWP is configured in an active state and performing one or more actions corresponding to the dormant BWP.
