  • Publication number: 20180324822
    Abstract: Embodiments of the present application propose a feedback method for an uplink channel, and an apparatus. In the solution, instead of always sending a first common message or a first scheduling command in any case, a base station determines, only after determining whether a data packet to be sent by a terminal is the last data packet of the terminal, whether a to-be-sent message including an indication bit that is used to indicate whether the base station correctly receives the data packet sent by the terminal is the first scheduling command or the first common message. Alternatively, when the base station determines that the terminal needs to send a next data packet or needs to retransmit the data packet, an indication bit for the terminal in at least two indication bits is used to indicate uplink control information. Therefore, this avoids a waste of resources.

  • Publication number: 20180317171
    Abstract: A system information sending method is provided, to resolve a technical problem that UE may not receive a paging message when a DRX cycle is greater than an MP. A network device may separately set a modification period (namely, a first period) for first-type system information (which, for example, may include paging configuration information), to ensure that the first-type system information is not to be modified in the first period. For example, the first period may be greater than a DRX cycle. In this way, when a terminal device wakes up based on the DRX cycle, a time when the terminal device wakes up is still in the first period. The terminal device may normally receive a paging message indicating that the paging configuration information is to be modified, thereby obtaining new paging configuration information in time and avoiding missing a subsequent paging message.

  • Publication number: 20180294931
    Abstract: A base station encodes antenna configuration information of a neighboring cell of a first cell, and sends encoded information relating to the antenna configuration information of the neighboring cell to a user equipment (UE). The UE is capable of communicating with the base station in the first cell. The UE receives the encoded information; decodes the antenna configuration information of the neighboring cell from the encoded information; and performs determination of predetermined time-frequency resource according to the antenna configuration information of the neighboring cell. The predetermined time-frequency resource is used by a base station of the neighboring cell for transmitting pilot measurement information.

  • Publication number: 20180255597
    Abstract: A method to transmit information includes: obtaining, by a terminal in a disconnected state, information about a current coverage class of the terminal; and sending, by the terminal, a first message to an access network device, where the first message carries information about a coverage class of the terminal. The terminal in the disconnected state actively reports the information about the coverage class, so that a network device learns of the information about the coverage class of the terminal in a timely manner. In this way, during communication, a communication limitation or communication resource waste caused by inconsistency between information about a coverage class of the terminal that is stored on a network side and information about an actual coverage class can be avoided, and network resources can be fully used.
