Abstract:
Method includes: determining, by a Access Point, AP, a duration of a time segment according to the number of sensor stations and a size of uplink data and a data transmission rate of the sensor stations in a network; wherein in the time segment, only sensor stations are allowed to perform access contention; sending, by the AP, a beacon frame, wherein the beacon frame carries information about the time segment.
Abstract:
Embodiments of the present invention provide a method for updating system information, an access network equipment, and a user equipment. Embodiments of the present invention can avoid the problem that, in the prior art, the user equipment is unable to correctly receive updated system information in that a subframe, configured by the user equipment supporting a half duplex data transmission mode in a system information receiving window corresponding to updated system information, may include an uplink subframe, or may further include an idle subframe, thus enhancing reliability of acquiring system information and reliability of data transmission.
Abstract:
Embodiments of the present disclosure provide a method and a device for transmitting data. The method includes: a user equipment receives downlink data sent from a base station through downlink resources of a special subframe; the user equipment determines its corresponding guard period level, the guard period level corresponds to a round-trip time of the user equipment and indicates a length of an orthogonal frequency division multiplexing (OFDM) symbol in a guard period corresponding to the user equipment in the special subframe; the user equipment determines, according to its corresponding guard period level, a position of uplink resources corresponding to the user equipment in guard period resources of the special subframe; and the user equipment sends uplink data to the base station through the uplink resources corresponding to the user equipment in the guard period resources of the special subframe.
Abstract:
The present disclosure provides a method and device for transmitting data. The method comprises: a first user equipment receives downlink data sent from a base station through downlink resources of a special subframe; the first user equipment acquires a position of uplink resources corresponding to the first user equipment in guard period resources of the special subframe, wherein the position of the uplink resources corresponding to the first user equipment in the guard period resources of the special subframe is staggered from a position of downlink resources corresponding to a second user equipment in the special subframe, and a round-trip time of the second user equipment is greater than a round-trip time of the first user equipment; and the first user equipment sends uplink data to the base station through the uplink resources corresponding to the first user equipment in the guard period resources of the special subframe.

Abstract:
The present invention discloses a method and a device for transmitting data. The method includes: sending, by a base station, a time-frequency resource on which a communication equipment sends any one preamble to the base station on a physical random access channel and corresponding relationship between a physical random access feedback channel and a physical random access channel to a user equipment on a downlink resource through system broadcast; sending, by the communication equipment, any one preamble to the base station on the time-frequency resource, receiving random access feedback information sent by the base station, performing synchronization with the base station through a TA carried in the random access feedback information, sending an RRC connection request message to the base station on the time-frequency resource biased with a preset time, receiving an RRC establishment message sent by the base station, and then establishing an RRC connection with the base station.
