  • Patent number: 10708172
    Abstract: A battery-powered node within a wireless mesh network performs energy-aware packet routing based on multiple factors. The battery powered node computes, for a given link to an adjacent node, the energy needed to transmit a packet to the adjacent node. The battery-powered node also determines the amount of battery energy remaining in the adjacent node. Based on these two factors, the battery powered node computes a link cost associated with the link to the adjacent node. The battery-powered node performs a similar computation for all adjacent nodes and then forwards packets via these adjacent nodes based on the associated link costs. The battery-powered node also maintains a table of routes through adjacent nodes, and reroutes packets through different adjacent nodes in response to link failures.

  • Patent number: 10701549
    Abstract: The invention relates to an improved grouping procedure performed by a master mobile terminal for grouping with a remote mobile terminal. The master mobile terminal and the remote mobile terminal are connected to a radio base station. The master mobile terminal may serve as a relay for remote mobile terminals so as to relay communication between the remote mobile terminals and the radio base station. A transmitter and receiver of the master mobile terminal discovers the remote mobile terminal and an identifier of the remote mobile terminal. The transmitter transmits a group request message to the radio base station, which comprises the remote mobile terminal identifier and a request to group the remote mobile terminal with the master mobile terminal. The receiver receives a group request confirm message from the radio base station, confirming that the remote mobile terminal and the master mobile terminal are grouped together.

  • Patent number: 10693605
    Abstract: A RACH preamble is transmitted from a UE using multiple antenna ports. A UE splits a data stream containing a RACH preamble into multiple streams corresponding to a same number of antenna ports of the UE. The UE multiplexes the copies of the RACH preamble according to a multiplexing scheme that enables a receiving eNB to discern the different channels used to transmit the signal from the different antenna ports. A RACH procedure is further accomplished in two steps instead of four by the UE then splitting a RACH payload to the same number of streams and multiplexing the RACH payload for transmission to the eNB. The eNB receives both transmissions, and may use the RACH preamble as a reference signal, and responds with a combined message with control information, random access response, and contention resolution information.

  • Patent number: 10693614
    Abstract: A data transmission method, including: receiving, by a terminal device on a first time domain resource, at least one piece of downlink data sent by a network device; and sending receiving status information to the network device on a second time domain resource. A transmission time interval of any piece of downlink data is less than a transmission time interval of the receiving status information, and the transmission time interval of the any piece of downlink data is less than 1 ms. According to the data transmission method, a transmission time interval of downlink data and a time interval between a sending time of the receiving status information and a receiving time of the at least one piece of downlink data are shortened, thereby reducing a latency.
