  • Patent number: 11134532
    Abstract: A radio communication system includes a radio access network (1) and a radio terminal (2). The radio access network (1) includes a first base station (11) that manages a first cell (110) and a second base station (12) that manages a second cell (120). The radio terminal (2) supports dual connectivity involving a bearer split in which a network bearer between the radio terminal (2) and a core network (3) is split over the first base station (11) and the second base station (12). The radio access network (1) is configured to transmit, to the radio terminal (2), first control information that relates to an access stratum and is necessary for the dual connectivity involving the bearer split. It is thus possible to provide, for example, a control procedure or signalling necessary for starting dual connectivity involving a bearer split.

  • Patent number: 11071029
    Abstract: A communication device may establish a second wireless connection with an external device in a case where a first wireless connection is established with the external device, determine whether a predetermined signal is received from the external device, and determine a preservation time according to the determination. The preservation time may be a time for preserving a state of the communication device in a parent station state after the second wireless connection has been disconnected. In a case where it is determined that the predetermined signal is received, one of a first preservation time and a second preservation time which is longer than the first preservation time may be determined as the preservation time, and in a case where it is determined that the predetermined signal is not received, the other of the first preservation time and the second preservation time may be determined as the preservation time.

  • Patent number: 10912051
    Abstract: Methods and devices for synchronizing a device clock in a wireless network (e.g. a LPWAN) are disclosed. Example methods comprise identifying a device temperature, identifying a clock drift associated with the identified device temperature and applying a correction to the device clock based on the identified drift. For the identified device temperature, the drift is identified by comparing the confidence of the drift value in a pre-calibration curve generated from fixed drift values in a pre-calibration table with the confidence of the drift value in a learning curve generated from variable drift values in a learning table and selecting the drift value from the curve having the higher drift confidence.

  • Patent number: 10897335
    Abstract: Systems and methods for signaling a pattern of cyclic shifts and orthogonal cover codes for use by a wireless device in multi-layer transmissions are presented. In one exemplary embodiment, a method includes receiving a signal that includes B bits for identifying a reference signal. Each of several available reference signals are defined by a cyclic shift and an orthogonal cover code. Further, the method includes using the B bits to identify the cyclic shift and orthogonal cover code according to pre-determined tables that map each value of the B bits to a pattern of cyclic shift and orthogonal cover code combinations for a multi-layer transmission scheme. The patterns for the multi-layer transmission scheme include first and second patterns based on the same cyclic shifts, but where some, but not all, of the cyclic shifts in the first pattern are associated with the same corresponding orthogonal cover codes in the second pattern.

    Abstract: Techniques are disclosed for aggregating bandwidth from multiple sources. In embodiments, a user device, such as a cellular telephone, may have a communications channel established with both a cellular tower and a wireless access point (WAP). When the user device transmits data, this data transmission may be divided between the multiple communications channels concurrently, so as to utilize the combined bandwidth of the multiple channels. Each communication channel may be prioritized, such as by prioritizing using the cellular channel until it is at capacity, and then using the WAP channel.
