Abstract: An approach to reduce the signaling overhead for tracking reference signal (TRS) configuration signaling to idle and inactive user equipments (UEs) operating in a wireless communication system. Conventional signaling approaches require more bits that can be conveyed in the maximum system information block (SIB) message size. One proposed approach optimizes the signaling by removing unnecessary or redundant information, using a single TRS configuration to replace multiple configurations, size reduction in some fields, and the sharing of some fields across different TRS configurations. Another proposed approach uses an SIB message to carry the TRS configurations for a particular beam or subset of beams. These two proposed approaches may be combined to provide further optimization possibilities.

Abstract: A user equipment (UE) is configured to simultaneously connect to a primary cell (PCell) and a primary secondary cell (PSCell) of a wireless network, wherein a primary component carrier (PCC) of the PCell and a primary secondary component carrier (PSCC) of the PSCell are both in frequency range 1 (FR1). The UE receives a PCC measurement object (MO) configuration, a PSCC MO configuration, and an inter-frequency MO with no measurement gap configuration, determines a PCC MO carrier specific scaling factor (CSSF), a PSCC MO CSSF, and an inter-frequency MO with no measurement gap CSSF and applies each respective CSSF to a measurement period corresponding to each of the PCC MO, the PSCC MO, and the inter-frequency MO with no measurement gap to determine a scaled measurement period corresponding to each of the PCC MO, the PSCC MO, and the inter-frequency MO with no measurement gap.

Abstract: Disclosed herein are system, method, and computer program product embodiments for enhancement in configured grant transmission. An embodiment operates by receiving a configured grant (CG) configuration message configuring a plurality of CG physical uplink shared channel (PUSCH) transmission occasions (TOs) within a CG period. Next, the embodiment receives an information element indicating a time division duplexing (TDD) uplink-downlink (UL-DL) slot configuration. The embodiment then determines whether a particular CG PUSCH TO of the plurality of CG PUSCH TOs overlaps with a DL slot indicated by the TDD UL-DL slot configuration. Finally, in response to a determination that the particular CG PUSCH TO overlaps with the DL slot, the embodiment skips utilizing the particular CG PUSCH TO.

According to embodiments of the present disclosure, a processor of user equipment is configured to perform following operations. The operations comprise transmitting to a network a user preference via a first signaling, wherein the user preference indicates a preference of the UE in uplink (UL) gap configuration; transmitting to the network an UL gap activation request via a second signaling, wherein the UL gap activation request indicates the network that an UL gap activation for the UE is needed; and transmitting to the network device an UL gap deactivation request via a third signaling, wherein the UL gap deactivation request indicates the network that an UL gap deactivation for the UE is needed.

Abstract: Approaches are described for receiving downlink signals simultaneously where analog beamforming is being used to increase the link budget between the base station and user equipment (UE). Alternatives within these approaches include the UE determining the synchronization signal block (SSB) to receive when there are multiple SSBs from different cells in a slot, and determining whether there are other signals in the same symbols with the selected SSB based on the type of signal and the SSB's functionality. In the case where there are another downlink signals channel state information-reference signal (CSI-RS) or physical downlink shared channel (PDSCH) from another cell, the UE selects the corresponding quasi co-location (QCL) assumption to receive the signals. Optionally, the UE can report whether it can support one or two QCL-TypeD at a time and whether it supports SSBs in different cells multiplexed in overlapped symbols.
