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: User equipment devices (UEs) may receive multimedia broadcast and multicast service (MBMS) transmissions over a bandwidth part (BWP) specifically allocated for MBMS point-to-multipoint (PTM) transmissions, or over MBMS-specific resources configured for PTM transmissions within a UE-dedicated BWP. The network (e.g. base station) may configure the MBMS-specific BWP for the UE for the PTM transmissions per serving cell. The MBMS-specific BWP may be used for downlink transmissions, and may be cell specific or UE specific per serving cell. The base station may provide MBMS PTM scheduling information per BWP to the UE, may indicate whether a UE-dedicated BWP may be used for PTM scheduling and transmission, and may provide the corresponding scheduling configuration when applicable. The UE may communicate its various capabilities related to MBMS reception and simultaneous reception of PTM and point-to-point (PTP) transmissions to the base station to aid the base station in scheduling communications of the UE.

IPC: H04W76/27

Abstract: While in an inactive state, a user equipment (UE) device transmits a message to a base station. The message indicates the UE device's intent to perform transmission and/or reception of user data with the network during the inactive state. The message may include a portion of the user data and/or a buffer status report. The UE device receives a response message that induces a state transition in the UE device. Different state transitions (e.g., to idle, inactive, legacy inactive, connected) may be induced by different types of response message (e.g., release, release with suspend configuration, resume, setup). One particular type of response message causes the UE to stay in the inactive state and enables subsequent user data transmission/reception in the inactive state. The response message may implicitly (or explicitly) indicate that forwarding of the user data to a core network was successful.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) to perform beam failure detection. The UE may establish communication with a base station. The UE may determine one or more beams to perform downlink communication from the base station. The UE may receive, from the base station, an indication of a first type of downlink reference signals to perform beam failure detection. The UE may perform signal quality measurements for the one or more beams using the first type of downlink reference signals. The UE may determine beam failure of at least one beam of the one or more beams based on said performing signal quality measurements.

Abstract: Methods and apparatuses are disclosed for performing fast beam switching in a high-frequency wireless communication environment. Higher frequencies reduce transmission wavelength, which allows for an increased number of antennas and an increased number of beams. Therefore, beams become narrower and are more prone to failure. The UE must be capable of quickly identifying the beam failure and switching to a new beam. Therefore, the UE is capable of receiving multiple beams from the base station and configures both for testing and immediate use. In some cases, the UE can receive multiple beams for testing and assumes a default beam while feeding back to the base station a preferred beam. To support the larger number of available beams, MAC-CE and DCI are modified to identify this increased number of states. Alternatively, two MAC-CEs are sent, each containing a different group of states, and the DCI identifies both the group and the selected state.

Abstract: Disclosed are methods and systems to coordinate resource allocation between two UEs for sidelink communication. A receiving UE receiving sidelink communication from a transmitting UE may configure coordination resources used to coordinate sidelink communication between the two UEs. The receiving UE may receive from the transmitting UE data indicating resources reserved and intended to be used by the transmitting UE to transmit sidelink data to the receiving UE. The receiving UE may determine a coordination message used to indicate whether the resources reserved by the transmitting UE are available for use by the receiving UE to receive the sidelink data from the transmitting UE. The receiving UE may determine resources from the coordination resources to be used to carry the coordination message and may transmit the coordination message carried on the selected resources to indicate to the transmitting UE whether to use the reserved resources for the sidelink data.

Abstract: A base station and a user equipment (UE) communicate the configure uplink communications in a multi-transmission and reception point (multi-TRP) configured network. The UE receives an indication of multiple sounding reference signal (SRS) resources that are to be used for uplink beam tracking, wherein each SRS resource is associated with different spatial relation information, transmits SRS using the associated spatial relation information, receives an indication that a user equipment (UE) is configured with one or more beam pairs, the one or more beam pairs configured by the network based on the SRS and transmits an uplink channel based on the indicated one or more beam pairs.
