In this embodiment, a message receiving method operating in the mobile terminal or the network architecture is provided, and fig. 2 is a flowchart of a message receiving method according to an embodiment of the present invention, as shown in fig. 2, the flowchart includes the following steps:
step S202, receiving a message sent by a base station through a downlink shared channel;
step S204, under the condition that the message is failed to be demodulated, the failure information of the message receiving failure is fed back to the base station, wherein the failure information is used for indicating the base station to resend the message.
Through the steps, because the feedback mechanism is provided when the terminal fails to receive the message, the problem that the success rate of the terminal receiving the message is low because the corresponding feedback mechanism does not exist for the terminal to successfully receive the message in the related technology can be solved, and the effect of improving the success rate of the terminal receiving the message is achieved.

Example 2
According to another embodiment of the present invention, a message sending method is further provided, and fig. 3 is a flowchart of a message sending method according to an embodiment of the present invention, as shown in fig. 3, the flowchart includes the following steps:
step S302, sending a message to a group of terminals through a downlink shared channel;
step S304, receiving failure information of the message receiving failure, wherein the failure information is fed back by one or more terminals in the group of terminals;
step S306, resending the message to the group of terminals.
Through the steps, because the feedback mechanism is provided when the terminal fails to receive the message, and the base station retransmits the message according to the feedback of the terminal, the problem that the success rate of the terminal receiving the message is low because no corresponding feedback mechanism exists for the terminal to successfully receive the message in the related technology can be solved, and the effect of improving the success rate of the terminal receiving the message is achieved.
Alternatively, the main body of the above steps may be a base station, etc., but is not limited thereto.
The embodiment of the invention provides a feedback mechanism for the shared channel, improves the success rate of data transmission on the shared channel and improves the user experience. The terminal receives the message from the shared channel, and when demodulation fails, the message information of the demodulation failure is fed back to the base station eNB through a specific mechanism so that the eNB can retransmit the message information, and the success rate of the terminal for receiving the message is improved.
Considering that there may be more groups in a cell and the distribution of terminals is more dispersed, in order to avoid reducing the system capacity due to a large number of retransmissions, an identifier may be added to the configuration message of the group call to inform the terminal whether the group call needs to feed back NACK when the message reception fails, and the eNB may set the identifier according to a certain policy, thereby controlling whether to allow retransmission of the message.
The following describes embodiments of the present invention in detail by way of specific examples.
Example 1
The principle is that the terminal carries out NACK feedback through a PUCCH, when the group user carries out NACK, the used PUCCH resource is obtained by calculation according to the position of the first CCE for scheduling the PDSCH by adopting the same mechanism as that of LTE, and the PUCCH resource does not need to be additionally configured. Fig. 4 is a first flowchart of a message retransmission method according to an embodiment of the present invention, as shown in fig. 4, including the following steps:
step 1: group calling is established;
step 2: an eNB schedules and sends messages on a shared channel, wherein two messages, namely packet a and packet b, are sent as an example;
and step 3: and the terminal receives and demodulates the message from the shared channel, finds that packet a has errors and feeds back NACK to the eNB.
And if the terminal successfully demodulates packet b, the ACK does not need to be fed back.
And 4, step 4: and the eNB retransmits the packet a, if part of the terminals successfully receive the packet a in the previous time, the successfully received message can be discarded according to the retransmission information of the DCI, or the retransmitted message can be discarded by using a repeated message discarding mechanism of the PDCP layer.
Example 2
The principle is that the terminal adopts the MAC CE to perform NACK feedback, and the MAC CE can expand the existing MAC CE in the cluster standard, and includes a group identifier (e.g., GID or tint), a downlink packet identifier (Process ID), and a NACK identifier, or newly defines an MAC CE (including a group identifier (e.g., GID or tint), and a downlink packet identifier (Process ID)) to report NACK. Fig. 5 is a second flowchart of a message retransmission method according to an embodiment of the present invention, as shown in fig. 5, including the following steps:
step 1: group calling is established;
step 2: an eNB schedules and sends messages on a shared channel, wherein two messages, namely packet a and packet b, are sent as an example;
step 3, step 4: the terminal receives and demodulates the message from the shared channel, finds that packet a has errors, and initiates random access if the terminal is in an idle state.
And 5: the terminal feeds back NACK of packet a to the eNB through the MAC CE. (if the terminal is not in the connected state, this step does not need to carry MSG 3);
step 6: and the eNB retransmits the packet a, and if the terminal successfully receives the packet a in the front, the successfully received message can be discarded according to the retransmission information of the DCI, or the retransmitted message can be discarded by using a repeated message discarding mechanism of the PDCP layer.
Example 3
The principle is that the terminal performs NACK feedback by using Radio Resource Control (RRC) messages, the RRC messages need to be respectively defined on an uplink CCCH and an uplink DCCH so as to meet the condition that the terminal reports NACK in an IDLE state and a connected state, and the RRC messages contain information such as G-RNTI or GID and a ProcessID of a downlink message so that the eNB can identify the message which needs to be retransmitted. Fig. 6 is a flow chart of a third method for retransmitting a packet according to an embodiment of the present invention, as shown in fig. 6, including the following steps:
step 1: group calling is established;
step 2: an eNB schedules and sends messages on a shared channel, wherein two messages, namely packet a and packet b, are sent as an example;
step 3, step 4: the terminal receives and demodulates the message from the shared channel, finds that packet a has errors, and initiates random access if the terminal is in an idle state.
And 5: and the terminal feeds back NACK of packet a to the eNB through RRC message. (if the terminal is not in the connected state, no MSG4 procedure follows);
step 6: the eNB retransmits the Packet a, and if the terminal has successfully received the Packet a in the foregoing, the eNB may discard the successfully received Packet according to the retransmission information of the DCI, or discard the retransmitted Packet by using a repeated Packet discarding mechanism of a Packet Data Convergence Protocol (PDCP) layer.
Through the above embodiments and application examples of the present invention, when the terminal receives the initial transmission message from the shared channel in error, the success rate of message reception can be greatly increased through the retransmission of the eNB, thereby improving the service quality and improving the user experience.
