Abstract: A method for communication, includes communicating over the air with a first user equipment (UE) in a frequency domain duplexing (FDD) mode, which defines a downlink channel comprising a first set of time-frequency resources in a first frequency range and an uplink channel comprising a second set of time-frequency resources in a second frequency range, which is disjoint from the first frequency range. An excess capacity is identified in the uplink channel, and at a least a portion of the excess capacity is allocated for downlink communication by assigning a subset of the time-frequency resources in the second frequency range to the downlink communication. The method includes communicating over the air with at least one second UE by transmitting downlink information using concurrently a given subset of the first set of time-frequency resources in the first frequency range and the assigned subset of the time-frequency resources in the second frequency range.

Abstract: A network device such as a router or switch, in one embodiment, includes a timing analyzer which is capable of providing timing analysis over one or more network circuits. The timing analyzer, in one aspect, receives a data packet traveling across a circuit emulation service (“CES”) circuit such as T1 or E1 circuit. Upon obtaining an arrival timestamp associated with the data packet, the arrival timestamp is stored in a timestamp buffer in accordance with a first-in first-out (“FIFO”) storage sequence. After identifying the oldest arrival timestamp in the timestamp buffer, an offset is generated based on the result of comparison between the arrival timestamp and the oldest timestamp. The timing analyzer can also be configured to generate timing reports on-demand based on generated offset(s).

Abstract: Certain networks can operate using circuit switched infrastructure, while other networks may operate using infrastructure for the long term evolution (LTE) of the third generation partnership project (3GPP). Devices can operate across the boundaries of these networks. Thus, such devices as well as the networks may benefit from network sharing in reverse single radio voice call continuity. For example, a method may include requesting handover of a user equipment from a source network to a target network. The method may also include providing a network identification corresponding to the source network while requesting the handover. Alternatively, or in addition, a method may include requesting handover of a user equipment from a source network to a target network. The method may also include determining the target network based on a network identification received previously.

Abstract: Embodiments of the disclosure generally relate to beam switching in a wireless communication network. A device in the wireless communication network determines a beam switch mode based on a first measurement on quality of a current beam serving a mobile terminal. The beam switch mode is associated with at least one candidate beam. Then, the device sends an indication of the beam switch mode to the mobile terminal to trigger the mobile terminal to perform a second measurement on a mobile reference signal associated with the at least one candidate beam. In response to receiving the second measurement from the mobile terminal, the device determines a target beam from the at least one candidate beam and the current beam based on the second measurement. In this way, the target beam may be determined in an efficient way.
