  • Patent number: 11943756
    Abstract: Bandwidth part (BWP) configurations supporting various communication approaches (e.g., full duplex and/or half duplex operations) are described. Full duplex (FD) frequency-based BWP configurations may, for example, be configured as a subset of defined BWP resources for supporting full duplex operation by base stations and/or user equipments (UEs). Usable bandwidth of a FD frequency-based BWP configuration may be selected from half duplex frequency-based BWPs in legacy BWPs. Bandwidths of usable BWPs for a FD frequency-based BWP configuration may be selected so as to be non-overlapping in frequency. Transition between configurations and modes (e.g., between full duplex frequency-based BWP configurations, between half duplex and full duplex modes, etc.) may be managed to avoid periods in which a communication device cannot perform any uplink or downlink transmissions due to switching between defined BWP configurations, or otherwise reduces BWP switching time.

  • Patent number: 11937193
    Abstract: Non-terrestrial networks (NTNs) may establish uplink (UL) and downlink (DL) radio frame timing structures to efficiently account for propagation delay and propagation delay variation associated with communications in the NTN. NTNs may manage (synchronize) radio frame timing structures of base stations (e.g., satellites) and user equipment (UEs) in the NTN. Further, UEs may determine timing advance (TA) values to be applied to UL transmissions based on their respective scheduling offset (e.g., offset in UL and DL radio frame timing structures), as well as based on propagation delay or round trip time (RTT). As such, served UEs may determine UL timing such that UL transmissions from the UEs to a satellite arrives at the satellite in a time synchronized manner. In other cases, a satellite may determine UL timing, based on reception timing, such that various UEs in the NTN may implement uniform UL and DL radio frame timing structures.

  • Patent number: 11937235
    Abstract: Aspects relate to dynamically changing the slot format of a slot between half-duplex and sub-band full-duplex and/or to changing flexible symbols within a flexible slot between half-duplex and sub-band full-duplex when a base station is configured to operate in a sub-band full-duplex mode. A slot format indicator (SFI) indicating the slot format of the slot may be signaled, for example, via downlink control information (DCI) mapped to a downlink control channel or medium access control (MAC) control element (MAC-CE) mapped to a downlink data channel. To improve reliability, various SFI boosting mechanisms may further be employed. For example, the base station may apply a higher aggregation level to the SFI, transmit repetitions of the SFI across multiple beams, apply a CRC enhancement and/or MCS enhancement to the downlink control channel carrying the SFI, and/or apply a power boost to the SFI.

  • Publication number: 20240089766
    Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may transmit capability information including an indication of a discontinuous monitoring delay period. The UE may receive a message including an indication to adjust monitoring of a physical downlink control channel (PDCCH), and monitor for the PDCCH during the discontinuous monitoring delay period. The UE may adjust monitoring for the PDCCH following the discontinuous monitoring delay period during a temporal period based on the received indication to adjust monitoring of the PDCCH. In some examples, at least one of physical downlink shared channel (PDSCH) reception, downlink reference signal monitoring, uplink reference signal transmissions, and channel reporting is enabled during the temporal period while monitoring of the PDCCH is adjusted.

  • Patent number: 11930521
    Abstract: The described techniques relate to improved methods, systems, devices, and apparatuses that support interference mitigation for remote devices. A first wireless device (e.g., a base station) may detect remote interference with its communications caused by a second wireless device (e. g., a second, remote base station) based on, for example, a measured interference over thermal noise level exceeding a threshold. The first wireless device may identify a set of time-frequency resources for remote interference reference signals and a data transmission for a user equipment (UE) that is in communication with the first wireless device. The first wireless device may transmit a remote interference signal to a second wireless device (e. g., a second base station) via the set of time-frequency resources. The first wireless device may further signal a resource allocation to the UE for the UE to use for transmitting uplink transmissions to the first wireless device.

  • Patent number: 11930451
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive, from a base station, control signaling indicating a set of connected discontinuous reception (C-DRX) configurations. The set of C-DRX configurations may include a first C-DRX configuration and a second C-DRX configuration, where at least one C-DRX configuration in the set of C-DRX configurations is a UE-group common C-DRX configuration. The set of C-DRX configurations may correspond to a discontinuous transmission (DTX) cycle of the base station. The UE may select a C-DRX configuration from the set of C-DRX configurations based on receiving the control signaling from the base station. Accordingly, the UE may use the selected C-DRX configuration to communicate with the base station. The selected C-DRX configuration may enable the base station to operate with reduced power consumption and higher DTX efficiency, among other benefits.
