Abstract: One or more methods of operating an access node. At least one of the methods includes: detecting a capability indication that indicates a capability of a user equipment (UE) to simultaneously receive and transmit (Rx/Tx) on a first component carrier (CC1) and a second component carrier (CC2); and scheduling, based at least on the capability, a first UE activity to occur over the CC1 and a second UE activity to occur over the CC2 to avoid a collision in a time-domain by prioritizing one of the first UE activity or the second UE activity relative to the other one of the first UE activity or the second UE activity.

Abstract: A method, UE and integrated circuit for reporting RSTD values to a network. A user equipment (UE) is configured to establish a connection to a network, the network comprising a first cell and a second cell. The UE receives a positioning reference signal from each of the first and second cells, determines a frequency band for each of the positioning reference signals, determines reference signal time difference (RSTD) values from measured time offsets between the positioning reference signals from the first and second cells, determines RSTD reporting values based on at least the RSTD values and the determined frequency bands and transmits an indication of the RSTD reporting values to the network.

Abstract: A user equipment (UE) includes a set of one or more transceivers and a processor. The processor is configured to determine, at least partly from a transmission control indicator (TCI) state for multiple channels, that common physical downlink shared channels (PDSCHs) do not share a beam with dedicated PDSCHs. The processor is also configured to determine a physical downlink control channel (PDCCH)/PDSCH scheduling offset is below a threshold; select, at least partly based on the determination that common PDSCHs do not share a beam with dedicated PDSCHs and the determination the PDCCH/PDSCH scheduling offset is below the threshold, a beam for which to buffer PDSCH; and buffer PDSCH received on the beam.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing downlink transmission and interlace uplink transmission. For example, some aspects of this disclosure relate to a base station including a transceiver configured to communicate over a wireless network with a user equipment (UE) and a processor communicatively coupled to the transceiver. The processor divides a plurality of candidate Synchronization Signal Block (SSB) positions in a time window into a plurality of groups and communicates, using the transceiver, information associated with the plurality of groups of candidate SSB positions to the UE. The processor further performs a listen-before-talk (LBT) procedure. In response to the LBT procedure being successful, the processor determines a first group of the plurality of groups and transmits, using the transceiver, one or more SSBs on one or more candidate SSB positions of the first group to the UE.

Abstract: A user equipment (UE) and a network agree on the use of a hybrid automatic repeat request (HARQ) codebook. The UE receives a plurality of downlink control information (DCI) transmissions during a corresponding plurality of physical downlink control channel (PDCCH) monitoring occasions from the base station, wherein each DCI transmission schedules multiple physical downlink shared channel (PDSCH) transmissions on a corresponding one of a plurality of component carriers (CCs), receives a time domain resource allocation (TDRA) table configuration from the base station, determines a maximum number of PDSCH transmissions per CC based on the TDRA table configuration, groups the plurality of CCs together and determines a hybrid automatic repeat request (HARQ)-acknowledgement (ACK) codebook size based on a number of the multiple PDSCH transmissions, the maximum number of PDSCH transmissions, and a resulting ACK or negative acknowledgement (NACK) for each of the multiple PDSCH transmissions.

Abstract: A user equipment (UE) may camp on a base station of a network. The UE receives, from the base station of a wireless network, a broadcast including access restrictions, wherein the access restrictions include one or more predetermined criteria that must be satisfied to camp on the base station. The UE then determines whether the UE satisfies the one or more predetermined criteria.

Abstract: Embodiments herein describe systems, apparatuses, and methods for adapting physical downlink control channel (PDCCH) monitoring behaviors. In some embodiments, a network node and a UE use search space set group switching to change PDCCH monitoring behavior. In some embodiments, a network node and a UE use PDCCH skipping to change PDCCH monitoring behavior. The PDCCH monitoring behavior may be indicated in a downlink control indicator (DCI).
