  • Methods and apparatus to facilitate multi-tasking and smart location selection during connected-mode discontinuous reception mode
    Patent number: 11172533
    Abstract: Apparatus, methods, and computer-readable media for facilitating multi-tasking and smart location selection during connected-mode discontinuous reception (CDRX) mode are disclosed herein. Example techniques disclosed herein enable a UE to perform multiple tasks during a same SSBS to reduce the number of wake-up SSBSs. For example, disclosed techniques enable a UE to perform RLM tasks and loop tracking tasks during a first SSBS and thereby reduce the number of wake-up SSBSs. In some examples, the UE may also perform the search task or the measurement task during the same first SSBS and, thereby, further reduce the number of wake-up SSBSs. Example techniques disclosed herein may also enable the UE to select which SSBS occurrences to wake-up for during the OFF duration of the CDRX cycle.

  • Excluding intra coded reference samples from local illumination compensation parameter derivation
    Patent number: 11172195
    Abstract: A rectangular block of video data is obtained, and the lengths of first and second sides of the block are determined. Intra-coded samples may be excluded from the first and/or second sides, or replaced with intra-coded samples from a reference block. Lengths of the first and second sides are determined based on non-excluded samples. Based on these lengths, a shortest or greatest side is selected. In some cases, additional samples may be excluded so that the total number of samples is a power of two. Illumination compensation parameters are determined based on remaining (non-excluded) samples neighboring the current block.

  • Network architecture and security with encrypted client device contexts
    Patent number: 11172357
    Abstract: In an aspect, a network may support a number of client devices. In such a network, a client device transmits a request to communicate with a network, establishes a security context, and receives one or more encrypted client device contexts from the network. An encrypted client device context enables reconstruction of a context at the network for communication with the client device, where the context includes network state information associated with the client device. The client device transmits a message (e.g., including an uplink data packet) to the network that includes at least one encrypted client device context. Since the network device can reconstruct the context for the client device based on an encrypted client device context, the network device can reduce an amount of the context maintained at the network device in order to support a greater number of client devices.

  • BEAM MEASUREMENT FOR A CELL SUBSET
    Publication number: 20210345201
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) measure and report cell measurements for neighboring cells to assist the wireless network with handover decisions. In some cases, the UE may be configured to report beam-level measurements for just a subset of neighboring cells instead of each neighboring cell. For example, the UE may measure, or report beam measurements for a subset of the neighboring cells which meet configured criteria or are included in a subset of cells configured by the serving cell. Techniques for configuring and maintaining the subset of cells are described herein. For example, the cells in the subset may be configured by the UE or the serving cell of UE. A cell may also be removed from the subset if the cell does not continue to meet criteria for being included in the subset.

  • Partial refresh technique to save memory refresh power
    Patent number: 11164618
    Abstract: In a conventional memory subsystem, a memory controller issues explicit refresh commands to a DRAM memory device to maintain integrity of the data stored in the memory device when the memory device is in an auto-refresh mode. A significant amount of power may be consumed to carry out the refresh. To address this and other issues, it is proposed to allow a partial refresh in the auto-refresh mode in which the refreshing operation may be skipped for a subset of the memory cells. Through such selective refresh skipping, the power consumed for auto-refreshes may be reduced. Operating system kernels and memory drivers may be configured to determine areas of memory for which the refreshing operation can be skipped.
