  • Patent number: 11716712
    Abstract: Certain aspects of the present disclosure relate to methods and apparatus for interference management with adaptive resource block (RB) allocation. In an exemplary method, a user equipment (UE) receives, from a base station (BS), an indication of a first set of resource blocks (RBs) to receive a first downlink (DL) transmission in a time interval, the UE receives, from the BS, an indication of a dynamically allocated second set of RBs to receive a second DL transmission from the BS in the time interval, and the UE alters one or more parameters of a receiver, based on the second set of RBs, when receiving the second DL transmission on the second set of RBs. Altering the one or more parameters may include switching a phase-locked loop (PLL) of the receiver to a center frequency determined based on the second set of RBs.

  • Patent number: 11711820
    Abstract: Aspects relate to the extension of cross-slot scheduling for power efficient paging between different New Radio (NR) operating platforms or environments. In some examples, the same paging downlink control information (DCI) may be shared between existing NR user equipment (UE) and new NR UE in different time slots, where a single paging DCI schedules multiple paging messages for each operating environment. In some examples, the same paging physical downlink control channel (PDCCH) occasion may be shared in existing NR and new NR operating environments for scheduling paging messages in different time slots, but different DCIs are used for scheduling the paging messages. In some examples, the same physical downlink shared channel (PDSCH) paging message may be shared in different slots between existing NR and new NR operating environments.

  • Publication number: 20230232413
    Abstract: Different sets of downlink control information (DCI) fields may be configured for DCI that includes an indication to trigger bandwidth part switching at a user equipment (UE). For example, a UE may receive DCI that triggers the UE to switch operation from a first bandwidth part to a second bandwidth part. The UE may also identify a set of transformable DCI fields and a set of non-transformable DCI fields within the DCI. The UE may then determine updated content of the DCI for application to the second bandwidth part based on whether DCI fields are included in the set of transformable or the set of non-transformable fields. In some cases, the UE may identify a null assignment in the received DCI and may switch its operation from the first bandwidth part to the second bandwidth part based on the null assignment.

  • Patent number: 11690087
    Abstract: Generally, the described techniques provide for duplex mode configuration for control information (e.g., duplex mode configuration for communication of downlink control information). For example, duplex modes may be defined (e.g., as full duplex (FD) capable, FD only, half duplex (HD) only, etc.), and such duplex modes may be configured for control resource sets (CORESETs), search space (SS) sets, or both. In some examples, duplex modes configured for a CORESET/SS set may depend on the priority of information conveyed via the CORESET/SS set. For example, a CORESET/SS set for high priority or critical control information may be configured with a HD mode to avoid FD self-interference, while CORESET/SS set for other control information may be configured with a FD mode to improve spectrum efficiency. Techniques for resolving conflicting duplex mode configurations (e.g., when a HD mode is configured for a SS set within a CORESET configured with FD) are also described.

  • Patent number: 11677520
    Abstract: Methods, systems, and devices for wireless communications are described that provide for allocation of control channel candidates for multiple component carriers (CCs) in carrier aggregation (CA) communications. A CA limit may correspond to a total number of configurable control channel candidates across multiple CCs. The control channel candidates may include blind decoding (BD) candidates or control channel element (CCE) candidates for channel estimation. A per-CC limit of control channel candidates may correspond to a number of configurable control channel candidates for each CC. An applied set of control channel candidates may be determined by allocating control channel candidates across the multiple CCs based on the CA limit and the per-CC limit. Such techniques may be used in cases where the CCs have a same numerology or mixed numerology, and may also be used for cross-carrier scheduling.

  • Patent number: 11671915
    Abstract: Certain aspects of the present disclosure provide techniques for coordinated sidelink power savings configurations. A wireless node may select a sidelink power savings configuration to use for a sidelink between the wireless node and a user equipment (UE), provide the selected configuration to the UE, and follow the configuration for the sidelink. The selection may be based on input from the UE or without input from the UE. The selection may be a current power savings configuration at the wireless node, a power savings configuration suggest by the UE, or a different power savings configuration determined by the wireless node based on the current and suggested power savings configuration. When a new UE connects to the wireless node, the wireless node may reselect a power savings configuration to use for the sidelinks and provide the reselected power savings configuration to the UEs having a sidelink with the wireless node.
