A technique is provided for transmitting client data included in a client signal via an optical transmission path of an optical transport network. The optical transport network uses transport frames include a transport frame period for transmitting client data. The method includes receiving multiple client entities comprising multiple client data bits; determining the number of client data entities received during a transport frame period to establish a mean number of client data entities to be included in a transport frame, the mean number of client data entities corresponding to a mean number of client data bits; mapping multiple client data entities into the transport frame wherein mapping comprises alternately adding and subtracting an amount of client data bits to/from the mean number of client data bits for at least two consecutive transport frames; and transmitting the transport frames comprising the client data via the optical transport network.

There is provided a transmission signal to enable tactile presentation at more positions than the number of channels of a tactile vibration signal that can be transmitted. The transmission signal includes audio signals of a predetermined number of channels and tactile presentation signals of a predetermined number of channels and to which metadata designating the tactile presentation position targeted by each of the tactile presentation signals of the predetermined number of channels is added is generated. The transmission signal is transmitted to a reception side via a predetermined transmission path. For example, the metadata is dynamically changed to dynamically change the tactile presentation position targeted by each of the tactile presentation signals of the predetermined number of channels.

Provided are a method and apparatus for sending and receiving a multiframe, a communication device, and a communication network system. The method includes: determining a multiframe identifier used for identifying a multiframe number according to a number of timeslots of a physical layer, where the multiframe number is the number of frames constituting one multiframe; and sending the multiframe to a receiving end, where the multiframe carries the multiframe identifier. Further provided is a computer storage medium.

A link group configuration method includes obtaining first status information of M links between a source end device and a receive end device, where the first status information indicates a status of a differential delay between any two of the M links, obtaining first capability information of the receive end device, where the first capability information indicates a first capability of performing differential delay compensation on the M links by the receive end device, grouping N of the M links into a first link group based on the first status information and the first capability information, and sending first configuration information to a second device, where the first configuration information includes information used to indicate the first link group.

The present disclosure discloses example method and apparatus for switching a line bandwidth of an optical transport network. One example method includes a network device switching an optical transport network (OTN) frame from a first bandwidth to a second bandwidth at a granularity of a substructure to generate a first OTN frame with the second bandwidth, where a bandwidth of the substructure is a specified value, and a difference between the first bandwidth and the second bandwidth is a multiple of the specified value. The first OTN frame with the second bandwidth is encapsulated as an encapsulated frame with the second bandwidth according to a first encapsulation protocol. The encapsulated frame with the second bandwidth is transmitted at an optical layer.

Embodiments of a User Equipment (UE) to support dual-connectivity with a Master Evolved Node-B (MeNB) and a Secondary eNB (SeNB) are disclosed herein. The UE may receive downlink traffic packets from the MeNB and from the SeNB as part of a split data radio bearer (DRB). At least a portion of control functionality for the split DRB may be performed at each of the MeNB and the SeNB. The UE may receive an uplink eNB indicator for an uplink eNB to which the UE is to transmit uplink traffic packets as part of the split DRB. Based at least partly on the uplink eNB indicator, the UE may transmit uplink traffic packets to the uplink eNB as part of the split DRB. The uplink eNB may be selected from a group that includes the MeNB and the SeNB.

Embodiments of a system and method for providing DRX enhancements in LTE systems are generally described herein. In some embodiments, a system control module is provided for controlling communications via a communications interface. A processor is coupled to the system control module and is arranged to implement an inactivity timer and an on-duration timer for determining an active time for monitoring subframes on the physical downlink control channel for control signals, the processor further monitoring subframes after the active time.

In some implementations, a method of wireless communications between a wireless communications network and wireless user equipment includes receiving, using a primary Time Division Duplex (TDD) configuration, data on a primary component carrier in a first frequency band. Using a secondary TDD configuration, data on a secondary component carrier is received in a second frequency band different from the first frequency band. A Hybrid Automatic Repeat Request (HARQ) for data received on the secondary component carrier is transmitted using a supplemental TDD configuration. A transmission or retransmission on the secondary component carrier uses a supplemental TDD configuration as well. The supplemental TDD configuration is different from the secondary TDD configuration. Furthermore, an uplink supplemental configuration may be different from a downlink supplemental configuration.

The described implementations relate a Passive Optical Network (PON). In one implementation, the PON includes an Optical Network Unit (ONU) that has at least one transmitter subsystem component and an associated optical transmitter. The at least one transmitter subsystem component may be configured to be in an enabled state during a timeslot period assigned to the ONU for transmitting an upstream data burst and a disabled state after the timeslot ends.

A method for processing service data in an optical transport network includes receiving service data, where the service data is to be mapped to a plurality of consecutive data frames, determining a quantity of code blocks, occupied by the service data, of each of the plurality of consecutive data frames and locations of the code blocks, where the code block includes a payload area and an overhead area, the payload area of the code block is used to carry the service data, and the overhead area of the code block includes identification information of the service data, and mapping the service data to the plurality of consecutive data frames based on the quantity of code blocks and the locations of the code blocks.
