  • Publication number: 20250008447
    Abstract: Aspects relate to supporting power control for physical uplink control channel (PUCCH) transmissions on an uplink secondary component carrier (SCC) of a wireless communication system. In some aspects, a user equipment (UE) receives a power control configuration from a base station for use by the UE for a PUCCH transmission on a selected uplink SCC. The UE then transmits, based at least in part on the power control configuration, the PUCCH to the base station on the selected uplink SCC. Closed-loop and open-loop power control examples are provided. In some aspects, common or shared power control configurations are provided by the base station for use with each component carrier of a PUCCH group. In other aspects, carrier-specific power control configurations are provided by the base station.

  • Patent number: 12185301
    Abstract: A wireless communication device can flexibly change subcarrier spacing (SCS) and/or cyclic prefix (CP) in wireless communication. The wireless communication device can transmit, in a first sidelink resource of a sidelink resource pool, a first sidelink transmission using a first configuration of subcarrier spacing (SCS) and cyclic prefix (CP). The wireless communication device can further transmit, in a second sidelink resource of the sidelink resource pool, a second sidelink transmission using a second configuration of SCS and CP, the second configuration being different from the first configuration in terms of at least one of an SCS or a CP. The techniques allow more efficient switching between SCS and CP configurations within a resource pool in the same bandwidth part.

  • Publication number: 20240430821
    Abstract: Methods, systems, and devices for wireless communications are described. Multiple component carriers may be configured for communications between communication devices, where uplink data channel resources may be scheduled on a component carrier of the component carriers. A communication device may report, over the uplink data channel resources to another communication device, a first report for available transmission power for uplink data transmissions over the component carrier and a second report associated with available transmission power for uplink control transmissions over a second component carrier. The other communication device may use the second report to determine the available transmission power for uplink control transmissions over the second component carrier. The other communication device may schedule communication resources based on the determined available transmission power for uplink control transmissions.

  • Publication number: 20240430741
    Abstract: This disclosure provides methods, components, devices and systems for enhanced downlink and uplink scheduling based on assistance information related to PDCP status reports. Some aspects specifically relate to a wireless communication system including a disaggregated base station architecture in which a CU provides a DU assistance information related to PDCP status reports from which assistance information the DU may determine appropriate downlink or uplink scheduling start timing for a UE. In some examples, the DU obtains from the CU assistance information indicating an unreceived PDCP SDU at a UE or the CU, and sends downlink data or an uplink grant to the UE based on the assistance information. The CU may deliver the downlink data to the DU prior to sending the assistance information or obtain uplink data from the DU after sending the assistance information. Duplication of PDCP SDU transmissions and unnecessarily extended scheduling delays may thus be minimized.

  • Patent number: 12156167
    Abstract: Disclosed are techniques for positioning. A receiver receives complementary timing information associated with the positioning reference signals (PRS) of a repetition of a PRS sequence. The complementary timing information distinguishes a repetition of a PRS sequence from remaining repetitions of the PRS sequence. Based on the complementary timing information associated with different PRS from different non-terrestrial vehicles indicating that the PRS were transmitted during the same radio frame, the receiver can determine an observed time difference of arrival (OTDOA) between the PRS received from the respective non-terrestrial vehicles.
