Abstract: An apparatus for wireless communication includes a receiver configured to receive a request for data associated with an Internet-of-things (IoT) service session with an IoT cloud server. The apparatus further includes a transmitter configured to transmit, based on receiving the request and prior to transmitting a response to the request, a message indicating a timing parameter associated with availability of the data. The receiver is further configured to receive an uplink grant at a time that is based on the timing parameter, and the transmitter is further configured to transmit the response to the request based on the uplink grant. The response includes at least a subset of the data.

Abstract: In an aspect, a UE may determine an initial transmission power for transmission of a physical random access channel (PRACH) preamble of a PRACH procedure based upon a final PRACH preamble transmission power associated with a set of historical completed PRACH procedures. The UE may further attempt an initial transmission of the PRACH preamble based on the determined initial transmission power.

Abstract: Embodiments of the present invention provide a communication method of an MTC terminal with low power consumption, which includes: sending, by the MTC terminal, a wireless channel request message to a base station through a random access channel; receiving, by the MTC terminal, an immediate assignment message delivered by a wireless network; and sending, by the MTC terminal, an MTC data report message to the wireless network, where the MTC data report message includes a unique identifier of the MTC terminal, authentication information and service data. The embodiments of the present invention further provide an MTC terminal with low power consumption, and a communication method and system of a wireless network with low power consumption, which can reduce power consumption of a wireless terminal during communication, so that the MTC terminal can maintain communication for a longer period of time.

Abstract: The present invention provides a data transmission method, a user equipment, and a network side device. The method includes generating a concurrency policy, which is used to indicate a user equipment to select at least one access network from at least two access networks to transmit at least one data stream. The concurrency policy is sent to the user equipment through a first data connection between a first access network in the at least two access networks and the user equipment.

Abstract: A data splitting method is provided and includes: sending, by a first device, a data connection request to a second device, so that the second device executes data splitting; and receiving, by the first device through at least two radio links in multiple radio links, split data that is sent by the second device according to the data connection request, where the first device establishes, via a third device, one link of the at least two radio links with the second device, and the at least two radio links in the multiple radio links include two radio links that are established by using different radio protocols. According to the foregoing technical solutions, downlink data may be sent to a user equipment through different radio links in a splitting manner, thereby increasing downlink bandwidth allocated to a user, and improving user experience with data services.
