  • Patent number: 11546968
    Abstract: A user equipment (UE) device may reside in a state of dual connectivity with a master cell group (MCG) and a secondary cell group (SCG), wherein the radio access technologies of the MCG and the SCG are different. While in the dual connectivity state, the UE device may transition to a mode of reduced activity (e.g., processing and/or RF activity) relative to the secondary cell group (SCG) in order to save power, e.g., when traffic flow via the SCG is below a threshold, or when scheduling activity on the SCG is low. Various mechanisms may be employed to reduce activity, e.g., mechanisms such as reduction of beam monitoring, deactivation of secondary cells of the SCG, reduction of number of active antenna elements, employment of longer periods for periodic measurement and reporting processes, etc.

  • Patent number: 11540262
    Abstract: Aspects of the disclosure relate to communication systems, apparatus and methods which enable or support transmitting/receiving downlink control information (DCI) carrying a downlink grant or an uplink grant. A method includes detecting a reference length based on an effective length of a downlink (DL) grant DCI and an effective length of an uplink (UL) grant DCI and calculating a length difference based on the effective DL grant DCI length and the effective UL grant DCI length. A length of a padding field in the DL grant DCI and/or the UL grant DCI is set equal to the calculated length difference such that the lengths of the DL grant DCI and UL grant DCI are both equal to the reference length. Padding bits are inserted in the padding field of the DL grant DCI and/or the UL grant DCI. Thereafter, the DL grant DCI and/or the UL grant DCI is encoded and transmitted to a scheduled entity.

  • Patent number: 11489785
    Abstract: A network traffic manager receives, from an ingress port in a group of ingress ports, a cell of a packet destined for an egress port. Upon determining that a number of cells of the packet stored in a buffer queue meets a threshold value, the manager checks whether the group of ingress ports has been assigned a token for the queue. Upon determining that the group of ingress ports has been assigned the token, the manager determines that other cells of the packet are stored in the buffer, and accordingly stores the received cell in the buffer, and stores linking information for the received cell in a receive context for the packet. When all cells of the packet have been received, the manager copies linking information for the packet cells to the buffer queue or a copy generator queue, and releases the token from the group of ingress ports.

  • Patent number: 11490382
    Abstract: Aspects of the present application provide for flexibility in configuring channel access occasions for uplink transmissions within a configured grant transmission resource duration. The uplink transmission may be transmitted in the physical uplink shared channel (PUSCH). The configured grant transmission resource duration includes multiple orthogonal frequency division multiplexed (OFDM) symbols. In some implementations, resources for uplink transmissions are allocated such that an integer number of equally sized mini-slots, each of which is considered a separate PUSCH, fit within the slot. This occurs when the number of OFDM symbols within the slot is evenly divisible by the number of OFDM symbols in the mini-slot. In some embodiments, not all of the mini-slots in the slot are equal in size. This occurs when the number of OFDM symbols within the slot is not evenly divisible by a particular mini-slot size.
