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 group call method, device and terminal, belonging to the field of communications technologies. The method includes: calculating, according to the load of a RAN device, the number of subgroups in a group maintained by the RAN device; and send a paging message carrying relevant information of the number of the subgroups, so that a terminal receiving the paging message determines, according to relevant information of the number of the subgroups, whether to respond to the paging message. The device is a RAN device or a CN device. The terminal includes a receiving module and a processing module. In the present invention, the number of paging groups and an in-group terminal being paged are determined dynamically without requiring a core network to maintain subgroup information, thereby greatly saving subgroup maintaining resources as well as signaling and processing resources.
Abstract:
Embodiments of the present invention disclose a method for retransmitting a message, mainly including notifying, by a terminal, a base station that the terminal is a narrowband terminal when sending a random access preamble to the base station; and when the base station subsequently detects that an error occurs to a message 3 sent by the terminal, instructing, by the base station, through a message 3 retransmission indicator, the terminal to retransmit the message 3, or retransmitting, by the terminal, the message 3 to the base station in a manner for actively retransmitting the message 3.
Abstract:
The present invention discloses a method for obtaining an Internet protocol header replacement mapping, which belong to the field of communications technologies. The method includes: obtaining, by a network node, fixed IP header information which is bound to a UE, where the network node is an MME or an eNB or a PGW or an SGW; establishing an IP header replacement mapping according to the fixed IP header information, where the IP header replacement mapping is correspondence between the fixed IP header information and an index or a bearer; and performing data transmission with the UE according to the IP header replacement mapping. In the present invention, the network node establishes the IP header replacement mapping according to the obtained fixed IP header information which is bound to the UE, the method is more flexible.
Abstract:
Media access control MAC payloads corresponding to a plurality of receiving devices are encapsulated in one MAC packet data unit (PDU), where the MAC PDU includes a header, the MAC payloads and identification information of each receiving device in the plurality of receiving devices; and the header includes a plurality of subheaders, the plurality of subheaders is subheaders respectively corresponding to a MAC payload corresponding to each receiving device, the MAC payload corresponding to each receiving device includes a MAC control element (CE) and/or a MAC service data unit (SDU), and the identification information is used for identifying each receiving device. In the foregoing solutions, transmission of a MAC PDU during multi-user cooperated communication is implemented.
Abstract:
Embodiments of the present invention provide a wireless broadband communication method, device, and system. The method provided in an embodiment of the present invention includes: establishing, by a macro base station, a Radio Resource Control (RRC) connection with a user equipment (UE); receiving, by a small cell, a configuration message sent, through a wired or wireless interface, by the macro base station; and establishing, by the small cell, a user plane connection between the small cell and the UE based on the RRC connection and the configuration message, and establishing a data bearer with the UE on the user plane connection.
Abstract:
Embodiments of the present invention disclose a method for selecting a control channel, and are applied to a communication system, to enable UE to select a control channel suitable for itself in a multi-control channel communications system. The method includes: listening, by UE, to a first control channel, and measuring a value of a performance parameter of a signal received by using the first control channel, and the first control channel is one of the at least two control channels; and when determining, according to the value of the performance parameter, that the first control channel meets a residence condition, determining the first control channel as a target control channel, where the target control channel is used to receive downlink control information sent by a base station.

Abstract:
Embodiments of the present invention disclose a method, a network device, and a base station for paging a narrowband terminal, where the method includes: determining that a paging message for paging a narrowband terminal needs to be sent; sending a paging message including narrowband terminal information to a base station, so that the base station obtains a radio capability of the narrowband terminal according to the narrowband terminal information and transmits the paging message according to the radio capability of the narrowband terminal. In the embodiments of the present invention, after it is determined that a paging message is used to page a narrowband terminal, because narrowband terminal information is added in the paging message, a base station is allowed to transmit the paging message according to a radio capability of the narrowband terminal.
