Abstract: An example method for wireless communication includes: configuring a wireless device to access a wireless network using a set of at least three components carriers (CCs); dividing the at least three component carriers into groups of component carriers based on whether the component carriers share a span pattern and a starting span for monitoring a Physical Downlink Control Channel (PDCCH) of each component carrier; determining a number of non-overlapping control channel elements (CCE) to monitor for each group of component carriers; and configuring the wireless device to monitor the non-overlapping CCEs based on the determined number to monitor for each group.

Abstract: Methods, systems, and devices for wireless communications are described. SSB based inter-frequency measurements may include configuring a UE to perform inter-frequency measurements without measurement gap within a measurement window, and applying scheduling restrictions to prioritize the inter-frequency measurements over uplink transmissions within the measurement window. The measurement window includes an SMTC window duration. Measurement resource sharing or restriction is described for SSB based inter-frequency measurement objects without measurement gap.

Abstract: Techniques discussed herein can facilitate successful decoding of Physical Downlink Shared Channel (PDSCH) based on a reduced number of retransmissions. Based on a given PDSCH, embodiments discussed herein can communicate feedback (e.g., Hybrid Automatic Repeat reQuest (HARQ) feedback, Channel State Information (CSI) feedback) that indicates an amount of additional information that can allow a User Equipment (UE) to successfully decode the PDSCH. In some embodiments, the feedback can indicate a requested Redundancy Version (RV) sequence that can allow the UE to successfully decode the PDSCH. In other embodiments, the feedback can indicate the amount of additional information, based on which a receiving Base Station (BS) can select a RV sequence.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) and/or cellular network to perform to perform cell detection and measurement, e.g., in new radio (NR) unlicensed (NR-U). The UE may determine that a threshold condition related to missed reference signal opportunities is reached. In response, the UE may modify reference signal monitoring and/or measurement.

Abstract: Methods and apparatus are provided for a UE to determine a UL spatial relation for an UL transmission in response to an unknown UL spatial relation switch. The UE may determine whether the UL spatial relation is based on an SRS transmission in UL, a CSI-RS in DL, or an SSB in the DL. If the UL spatial relation is based on the SRS transmission, the UE may select the UL spatial relation for the UL transmission corresponding to a Tx beam of the SRS transmission. If the UL spatial relation is based on the CSI-RS or the SSB, the UE may select the UL spatial relation for the UL transmission based on whether the unknown UL spatial relation switch s due to a corresponding resource for beam training not being configured by a communication network or a corresponding beam information being expired.

Abstract: Apparatuses, systems, and methods for enhancement of MBMS transmission reliability. A UE may receive PDCP PDUs via a PTM link from a network. The UE may determine to provide feedback regarding receipt of the PDCP PDUs, e.g., based, at least in part, on an occurrence of a triggering event. The triggering event may be configured by the network and may include the UE receiving a request for feedback from the network, the UE determining that at least one PDCP PDU is missing, the UE determining that a number of missing PDCP PDUs exceeds a threshold, and/or the UE determining that a PDCP reordering window is changing based on expiration of a PDCP reordering timer. The UE may transmit feedback associated with receipt of the PDCP PDUs. The feedback may include an indication of missing PDCP PDUs, e.g., such as an indication of a sequence number associated with missing PDCP PDUs.

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.

Abstract: Apparatuses, systems, and methods for radio resource management (RRM) signal reception. A user equipment device (UE) may receive, via a first reception path, an RRM related signal and receive, via a second reception path, a non-RRM related signal that may be multiplexed with the RRM related signal onto a symbol. The first reception path may be a first antenna port of an antenna panel or a first antenna panel of the UE and the second reception path may be a second antenna port of the antenna panel or a second antenna panel of the UE. The RRM related signal may include a reference signal for RRM. and may be included in a non-zero power (NZP) interference measurement.
