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: To extend a physical broadcast channel (PBCH) in wireless communications, an extended physical broadcast channel (EPBCH) transmission is generated with one or more legacy PBCH blocks and one or more EPBCH blocks within an extension window. A size of the extension window is determined based at least in part on a PBCH repetition number and a number of the legacy PBCH blocks relative to a number of the EPBCH blocks. The EPBCH transmission is transmitted by a base station (BS) to one or more user equipment (UE).

Abstract: Systems, methods and devices can are provided, which can include configuring one or more bandwidth parts for a secondary cell (SCell) that is in communication with a user equipment (UE). A base station transmits to a UE a first radio resource control (RRC) message including one or more configuration parameters for a first bandwidth part (BWP) associated with a secondary cell (SCell). The UE communicates a first message with the SCell via the first SCell BWP. The UE receives a second RRC message indicating a change from the first SCell BWP to a second SCell BWP to be used for SCell communications. The UE communicates a second message with the SCell via the second SCell BWP.

Abstract: To reduce the beam reporting latency, a base station may include a sounding reference signal (SRS) indication to a wireless communication device (UE) as part of the transmission configuration information (TCI) transmitted to the UE, allowing the UE to receive a corresponding downlink signal using the same beam (or with the same beam) the UE used to transmit (or with which the UE transmitted) the SRS indicated in the TCI. The SRS may be one of multiple SRSs previously transmitted by the UE. The UE may transmit the multiple SRSs periodically and/or according to semi-persistent scheduling, or it may transmit them aperiodically. Therefore, the UE does not need to report the beam quality, and the base station may perform the necessary beam measurement(s) instead. Various parameters and conditions may be defined for the UE to support SRS-based TCI.

Abstract: An example method for wireless communication includes: receiving, by a user device in a reduced power state, resource information for receiving a channel state information reference signal (CSI-RS) and tracking reference signal (TRS); exiting the reduced power state to receive the CSI-RS and TRS, based on the resource information; synchronizing with a base station, based on the received CSI-RS and TRS, to receive a downlink control information message; receiving paging information in a first physical downlink shared channel (PDSCH) transmission based on the received downlink control information message; determining whether there is paging information in the first PDSCH transmission for the user device; starting a Random Access Channel (RACH) procedure to make a Radio Resource Control (RRC) connection, based on determining that there is paging information for the user device; and returning to the reduced power state, based on determining that there is not paging information for the user device.

Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to determine a default beam for a dedicated PUCCH/SRS in a CC. The UE may determine a pathloss RS has been configured in the CC, e.g., responsive to the UE determining that spatial relationship information for a default transmission beam has not been configured and determine the default beam for transmissions based, at least in part, on the (configured) pathloss RS. Additionally, responsive to determining that the pathloss RS has not been configured in the CC, the UE may determine that no CORESETs/TCI states for a PDSCH in the CC have been configured and determine the default beam for transmissions based, at least in part, on a default transmission beam in another CC, a CC index, a PRACH procedure; a PUSCH transmission; an SRS transmission, and/or a PUCCH transmission.

Abstract: Techniques are described for improving service continuity for Multicast and Broadcast Services (MBS) communications during handover. Techniques are included for supporting lossless handover and data forwarding during handover for peer-to-multiple (PTM) MBS transmission. Lossless handover may be achieved in part by the user equipment (UE) providing to the target base station an indication of the next packet of the MBS session to be received following an RRC reconfiguration message, and an indication of any MBS packets provided by the source base station prior to the RRC reconfiguration message that were not properly received by the UE. Data forwarding may be performed from the source base station to the target base station if the MBS session was not configured on the target base station prior to the handover. Data forwarding may be omitted if the MBS session was configured on the target base station prior to the handover.

Abstract: The techniques described herein may include a device, comprising: a memory; and one or more processors configured to, when executing instructions stored in the memory, cause the device to: communicate, via a wireless communication network, information as in-order traffic using an in-order radio link control (RLC) entity; and communicate, via the wireless communication network, information as out-of-order traffic using an out-of-order RLC entity. The in-order traffic and the out-of-order traffic may be communicated using the same data radio bearer (DRB). The out-of-order traffic may include selective out-of-order delivery (OOD) or per-packet OOD. Additional examples, features and other techniques are also described herein.

Abstract: This disclosure relates to techniques for physical downlink control channel handling when a secondary cell group is activated in a wireless communication system. A wireless device may establish a wireless link with a master cell group. A secondary cell group may be configured. The wireless device may receive an indication to activate the secondary cell group without performing a random access channel procedure on the secondary cell group. The wireless device may determine quasi-co-located information for a physical downlink control channel of the secondary cell group. The wireless device may perform physical downlink control channel decoding for the physical downlink control channel of the secondary cell group using the determined quasi-co-located information.

Abstract: Techniques discussed herein can facilitate configuration of a User Equipment (UE) with two or more Discontinuous Reception (DRX) configurations. A first set of techniques can facilitate configuration of the UE with independent DRX configurations for Frequency Range 1 (FR1) and for Frequency Range 2 (FR2). A second set of techniques can facilitate configuration of the UE with independent DRX configurations for a first set of one or more Component Carriers (CCs) associated with a first frequency band of a supported band combination and for a second set of one or more CCs associated with a second frequency band of the supported band combination. Various embodiments can employ techniques of one or more of the first set of techniques or the second set of techniques.
