  • Patent number: 11129062
    Abstract: Methods and apparatus for storing, manipulating, retrieving, and forwarding state, e.g., context and other information, used to support communications sessions with one or more end nodes, e.g., mobile devices, are described. Various features are directed to a mobile node controlling the transfer of state from a first access node to a second access node during a handoff operation thereby eliminating any need for state transfer messages to be transmitted between the second access node and the first access node during handoff. Other features of the invention are directed to the use of a core network node to store state information. State information stored in the core node can be accessed and used by access nodes in cases where a mobile node does not send a state transfer message during a handoff, e.g., because communication with the first access node is lost or because such messages are not supported.

  • Patent number: 11101918
    Abstract: Techniques are described for wireless communication at a wireless device. One method includes transmitting, during a TTI, a first message using a first MCS; and transmitting, during the TTI, a second message using a second MCS. The first message includes indications of a location, a heading, and a speed of the wireless device, and the second MCS is higher than the first MCS. Another method includes decoding a first message received during a TTI; performing a Doppler effect compensation for a second message based at least in part on the first message; and decoding the second message based at least in part on the Doppler effect compensation. The second message is also received during the TTI. The first message is decoded in accordance with a first MCS, and the second message is decoded in accordance with a second MCS, with the second MCS being higher than the first MCS.

  • Publication number: 20210051527
    Abstract: The disclosure relates in some aspects to sharing wireless communication resources. For example, a first type of device allocated to use a first resource pool may dynamically use a second resource pool allocated for a second type of device. The first type of device may use an entry criteria to determine whether to use the second resource pool. In some aspects, the entry criteria may specify that resource sharing is permitted if a ratio of resources used by devices of the second type (relative to the total resources in the second resource pool) is less than a threshold. In addition, the first type of device may use an exit criteria to determine whether to stop using the second resource pool. In some aspects, the exit criteria may specify that resource sharing should stop if a ratio of resources used by devices of the second type is greater than a threshold.
