  • Patent number: 10728867
    Abstract: The solution presented herein controls a transmission timing of data from multiple transmission points to synchronize the data reception at a receiver to within pre-specified limits. To that end, a skew timing is determined from a difference between a second delay (a transmission time between the master node and a second slave node) and a first delay (a transmission time between a master node and a first slave node). A deadzone mapping is applied to the initial liming error (determined from a difference between a reference skew timing and the skew timing) to determine a final timing error. The deadzone mapping is configured to adjust the initial timing error responsive to a comparison between the initial timing error and a timing error range. The first and second delays are controlled using the final timing error to keep the skew timing within the timing error range.

  • Patent number: 10608857
    Abstract: This application discloses a reference signal configuration method and apparatus. Before a network device sends reference signals aperiodically, the network device sends configuration information to a terminal device, where the configuration information is used to indicate a timeslot offset of one or more reference signal resource sets. Therefore, the network device can flexibly send reference signals in different timeslots, thereby reducing a quantity of times of reference signal triggering and measurement result reporting, and improving efficiency of a communications system.

    Abstract: Disclosed herein are methods, systems, and processes for managing raw device mapping during disaster recovery. A raw device mapping (RDM) file operation is assigned to a virtual device associated with a virtual machine that is replicated from a premise site. A determination is made that a RDM file associated with the virtual device is invalid or is not replicated after the virtual machine is replicated to a target site. Based on the determination that the RDM file is invalid or is not replicated, the virtual device is removed from the virtual machine and the assigned RDM file operation is performed.

    Abstract: Techniques are described to provide for re-timing a packetized radio flow to clean noise induced by packet delay variation of a packet network. In one example, a method includes receiving, at a first node of a fronthaul network, a Radio over Ethernet (RoE) frame transmitted by a second node in which the RoE frame comprises a Common Public Radio Interface (CPRI) bit stream associated with a first radio device, a sequence number, and a first time stamp. The method may further include generating a second time stamp by the first node upon obtaining the RoE frame; calculating an induced delay value based, at least in part, on the first time stamp and the second time stamp; calculating a re-timing value based on a re-timing interval and the induced delay value; and transmitting the CPRI bit stream to a second radio device based on the re-timing value.

  • Patent number: 10588156
    Abstract: Enhanced random access procedures for link-budget-limited user equipment (UE) devices are disclosed. A user equipment device may transmit a first message containing a Physical Random Access Channel (PRACH). The PRACH contains instances of a Zadoff-Chu sequence, and may be transmitted repeatedly as part of a single random attempt, to facilitate correlation data combining at the base station. The available Zadoff-Chu sequences may be partitioned among a plurality of sets, each set being associated with a respective Doppler shift range (or frequency hop pattern or time repetition pattern). A UE device may signal Doppler shift (or other information) to the base station by selection of one of the sets. The first PRACH transmission and the following PRACH transmission may occur in consecutive subframes. A UE device may select from a special set of Zadoff-Chu sequences (different from a conventional set of sequences), to signal its status as a link-budget-limited device.

    Abstract: A method for transmitting control commands in a system (100) of units (L1-L18) in a distributed arrangement, for example in a lighting system having luminaires in a distributed arrangement, involves at least some of the units (L1-L18) sending a received control command again in order to ensure that the control command is forwarded to all units (L1-L18). The control command contains a piece of information regarding an already past command transmission time, wherein each unit (L1-L18) takes the command transmission time that a received command contains as a basis for determining an individual waiting time (TTLind), after the expiry of which the command is executed by the unit (L1-L18).

The random access method includes: determining, by a terminal, whether a resource used for random access conflicts with a resource used for receiving a downlink signal; and if the resource used for the random access conflicts with the resource used for the downlink signal, preferentially using the conflicting random access resource for receiving the downlink signal but not for the random access. This avoids a conflict between receiving of the downlink signal and sending of an uplink random access preamble.
