  • Patent number: 11985645
    Abstract: Reporting UL Tx DC sub-carrier location information may include decoding a radio resource control (RRC) message received from a base station. The RRC message may comprise a configuration for dynamically reporting uplink (UL) transmit (Tx) direct current (DC) sub-carrier location information. A change associated with at boast one previous UL Tx DC sub-carrier location may be determined to have occurred, thereby creating at least one new UL Tx DC sub-carrier location. In response to determining the change, a medium access control (MAC) control element (MAC CE) may be encoded for transmission to the base station. The MAC CE may include information corresponding to the at least one new UL Tx DC sub-carrier location.

  • Patent number: 11985652
    Abstract: Systems and methods for enhancing the use of pre-emptive buffer status reports (pre-BSRs) in wireless communications systems implementing integrated access and backhaul (IAB) networks are disclosed herein. In some cases, an IAB node can re-classify the LCGs of one or more incoming data flows according to such pre-BSR usage. This may involve the use of and extended medium access control (MAC) control element (MAC CE) having more LCG bits than previously contemplated, having sub-LCG bits, or that includes further LCG classification information bits. Other embodiments use a priority index for LCGs in an extended pre-BSR MAC CE. The priority index may include one or more of a priority field, a prioritized bit rate (PBR), and/or a bucket size duration (BSD) that is reported to an IAB donor. Other embodiments leverage the provision of additional grants from an IAB node to a child IAB node to reduce unwanted pre-BSR effects.

  • Publication number: 20240130071
    Abstract: An outdoor electric cabinet and an air duct structure thereof are provided. The air duct structure is used to guide airflow to an air inlet side of a fan. The air duct structure includes an air inlet port, a flow-guiding cavity and an air distribution assembly. The air inlet port is configured to introduce external airflow into the air duct structure. The flow-guiding cavity is formed between the air inlet port and the air inlet side of the fan. The air distribution assembly is arranged in the flow-guiding cavity to uniformly distribute an air suction force of the air inlet port. The airflow suction force at the air inlet port is distributed more uniformly by the air distribution assembly, which effectively weakens the maximum wind speed on the shortest path.

  • Patent number: 11963056
    Abstract: Layer 2 handling during a cell change procedure includes decoding an RRC reconfiguration message received from a first cell. The RRC reconfiguration message includes a Layer 1 (L1) configuration corresponding to a second cell. The first cell and the second cell share an SDAP entity, a PDCP entity, an RLC entity, and a MAC entity. The first cell and the second cell have a separate L1 entity. In response to decoding the RRC reconfiguration message, the L1 configuration corresponding to the second cell is stored. A cell change message received from the first cell is decoded. The cell change message indicates that a cell change from the first cell to the second cell is to be performed. The stored L1 configuration corresponding to the second cell is applied for data transmission and reception associated with the second cell. A cell change to the second cell is initiated.
