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.

Abstract: A user equipment (UE) monitors a Physical Downlink Control Channel (PDCCH) in multiple component carriers (CC). The UE determines if the UE is operating in carrier aggregation (CA) mode having a first CC in a first frequency band and a second CC in a second frequency band. When the UE is operating in CA with a first CC in the first frequency band and the second CC in the second frequency band, the UE determines a span pattern for PDCCH symbols being received on the first and second CC and selects a PDCCH monitoring type based on, at least, the span pattern. A UE also determines if a first CC and a second CC of a CA combination are collocated and selects a PDCCH monitoring type based on, at least, the determination of whether the first and second CC are collocated.

Abstract: Some aspects relate to a carrier aggregation wireless system having a user equipment (UE). The UE can generate a report of a UE capability to support a first downlink control information (DCI) in a first DCI format for a cell of a plurality of cells of the wireless system and a second DCI in a second DCI format for the cell, and a report of a UE capability to support splitting a blind decoding (BD) of control channel element (CCE) (BD/CCE) budget between performing BD/CCE carrying the first DCI in the first DCI format, and performing BD/CCE carrying the second DCI in the second DCI format. The first DCI in the first DCI format can schedule data transmissions for a set of multiple cells. The UE may perform BD/CCE carrying the first DCI in the first DCI format, and perform BD/CCE carrying the second DCI in the second DCI format.

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: A user equipment (UE) is configured to communicate with a further UE via a sidelink (SL). The UE encodes traffic for transmission to the further UE, wherein the traffic comprises a payload and a medium access control (MAC) subheader, wherein the MAC subheader indicates whether the payload corresponds to non-routed traffic between the UE and the further UE or routed traffic between either one of the UE or the further UE and a base station, wherein an other one of the UE or the further UE functions as a relay for the routed traffic and transmits the traffic.

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.

Abstract: Embodiments of the present disclosure relate to Physical Uplink Control Channel (PUCCH) reliability enhancement. According to embodiments of the present disclosure, a processor of a UE receives, from a BS associated with a first TRP and a second TRP, a first message for configuring a PUCCH resource to be used by the UE to perform a PUCCH transmission with the BS. In this case, the first message indicates a first configuration corresponding to the first TRP and the first configuration comprises at least one power control parameter associated with the first TRP. The message further indicates a second configuration corresponding to the second TRP and the second configuration comprises at least one power control parameter associated with the second TRP. The processor performs the PUCCH transmission with the BS via the first and second TRPs based on the first message. In this way, the reliability and robustness of the PUCCH transmission for multiple TRP is enhanced.
