For example, the network side or the protocol stipulates that the identifier of the first packet (e.g., PDCP SDU) is a specific identifier, such as a data flow identifier, a data radio bearer identifier, a session identifier, or a logical channel identifier, and when the transmission delay of the first packet with the specific identifier exceeds a first predetermined time period, or the network side indicates that the first packet with the specific identifier is to be discarded, or the transmission delay of a packet associated with the first packet with the specific identifier exceeds a second predetermined time period, the MAC entity of the terminal discards the first packet with the specific identifier.
For another example, the MAC entity of the terminal may identify the first packet according to the packet size, which is illustratively smaller than a threshold value of 10 bytes (byte) defined by the network configuration or protocol, and this type of packet is identified as an insignificant packet. That is, when the size of the first data packet is equal to or greater than 10 bytes, and the transmission delay of the first data packet exceeds a first predetermined time period, or the network side indicates that the size of the data packet of the first data packet to be discarded is equal to or less than 10 bytes, or the size of the first data packet is equal to or greater than 10 bytes, and the transmission delay of the data packet associated with the first data packet exceeds a second predetermined time period, the MAC entity of the terminal discards the first data packet whose size is equal to or less than 10 bytes.
In an embodiment of the present application, the HARQ information includes at least one of: (1) numbering the HARQ processes; (2) second information indicating whether a HARQ process is required to be retransmitted, the HARQ process including the first data packet.
In this embodiment of the present application, the MAC entity of the terminal may discard the specified data packet, for example, the transmission delay of the specified data packet exceeds a predetermined time length, or the specified data packet indicates a data packet to be discarded for the network side, or the transmission delay of a data packet associated with the specified data packet exceeds a predetermined time length, so as to save data transmission resources.
Referring to fig. 4, the specific steps include steps 401 to 403.
Step 401: according to the configuration or protocol convention of the network side, when the transmission delay of the first data packet exceeds a first preset time, or when the first data packet indicates a data packet to be discarded for the network side, or when the transmission delay of the data packet related to the first data packet exceeds a second preset time, the MAC entity of the UE discards the first data packet.
Wherein the identifier of the first data packet comprises at least one of:
(1) a data stream identification;
alternatively, the data flow identification may be a Quality of Service flow (Quality of Service flow), such as, for example, QoS flow-1;
(2) data Radio Bearer (DRB) identity, e.g., DRB-1;
(3) session identification, e.g., PDU Session-1;
(4) a Logical Channel IDentifier (LCID), such as LCID-1.
(5) The size of the data packet is smaller than a threshold value set by network configuration or protocol;
optionally, the time range of the predetermined time is agreed by network configuration or protocol.
Optionally, when the sending delay of the first data packet exceeds a predetermined time, the MAC entity of the UE determines whether to discard the first data packet according to a preset discarding judgment condition, and discards the first data packet if the discarding judgment condition is met, or does not discard the first data packet otherwise.
Wherein, the discarding judgment condition includes any one of:
(1) condition 1: if the MAC PDU contains only the first data packet exceeding a predetermined time period, the MAC entity of the UE discards the MAC PDU.
For example, the MAC PDU-1 includes MAC SDU-1 (from logical channel-1) and MAC SDU-2 (from logical channel-2), where the logical channel-1 and the logical channel-2 are both logical channels configured on the network side and capable of discarding MAC data, and the transmission delays of the MAC SDU-1 and the MAC SDU-2 both exceed a predetermined time length, then the MAC entity of the UE discards the MAC PDU.
For example, the MAC PDU-1 includes MAC SDU-1 (from logical channel-1) and MAC SDU-2 (from logical channel-2), where only logical channel-1 is a logical channel configured on the network side and capable of discarding MAC data, and the MAC entity of the UE does not discard the MAC PDU-1.
For example, the MAC PDU-1 includes MAC SDU-1 (from logical channel-1) and MAC SDU-2 (from logical channel-2), where both logical channel-1 and logical channel-2 are logical channels configured on the network side and capable of discarding MAC data, and only if the transmission delay of MAC SDU-1 exceeds a predetermined time, the MAC entity of the UE does not discard the MAC PDU.
Condition 2: and if the MAC PDU contains the first data packet exceeding the preset time length, the UE reconstructs the MAC PDU and discards the MAC PDU, and the reconstructed MAC PDU does not contain the first data packet exceeding the preset time length.
For example, the MAC PDU-1 includes MAC SDU-1 (from logical channel-1) and MAC SDU-2 (from logical channel-2), where both logical channel-1 and logical channel-2 are logical channels configured on the network side and capable of discarding MAC data, and only if the transmission delay of MAC SDU-1 exceeds a predetermined time, the MAC entity of the UE reconstructs MAC PDU-1 to obtain MAC PDU-2 and discards MAC PDU-1, and the MAC PDU-2 does not include MAC SDU-1.
For example, the MAC PDU-1 includes MAC SDU-1 (from logical channel-1) and MAC SDU-2 (from logical channel-2), where only logical channel-1 is a logical channel configured on the network side and capable of discarding MAC data, and the transmission delay of MAC SDU-1 exceeds a predetermined time length, the MAC entity of the UE reconstructs the MAC PDU-1 to obtain MAC PDU-2, and the MAC PDU-2 does not include MAC SDU-1.
The MAC entity of the UE discards the first packet, which may include any one of the following:
(1) the MAC entity of the UE empties the buffer of the HARQ process containing the first data packet.
For example, after the MAC entity of the UE determines to discard the MAC PDU-1 packet, the MAC PDU-1 is buffered in the HARQ process-1, and then the UE empties the buffer of the HARQ process-1.
(2) The MAC entity of the UE stops the retransmission of the HARQ process containing the first data packet.
For example, after the MAC entity of the UE determines to discard the MAC PDU-1 packet, the MAC PDU-1 is buffered in the HARQ process-1, and if the UE receives the retransmission instruction of the HARQ process-1 again, the UE does not retransmit the HARQ process-1 containing the MAC PDU-1.
Step 402: and the UE sends first information to the network side equipment, wherein the first information indicates the HARQ information corresponding to the discarded data packet.
Wherein the HARQ information may include at least one of:
(1) HARQ process number, e.g., HARQ process-1.
(2) Second information indicating whether to retransmit the discarded packet, for example, 1bit indicates whether to retransmit the discarded packet.
For example, a Physical Uplink Shared Channel (PUSCH) of the UE includes Uplink Control Information (UCI) and data Information, where the UCI includes 1-bit indication Information, and a value 1 indicated by the indication Information indicates that the HARQ process corresponding to the PUSCH does not retransmit the discarded data packet any more.
The indication information can be sent in any one of the following manners:
(1) sending through UCI;
(2) transmitting through a MAC CE (Control Element);
(3) sent through RRC messages.
Step 403: and after receiving the indication information, the network side equipment stops the retransmission of the HARQ process.
For example, the HARQ process is instructed to transmit new data, or the data for the HARQ process is successfully received.
In this embodiment of the present application, the MAC entity of the terminal may discard the specified data packet, for example, the transmission delay of the specified data packet exceeds a predetermined time length, or the specified data packet indicates a data packet to be discarded for the network side, or the transmission delay of a data packet associated with the specified data packet exceeds a predetermined time length, so as to save data transmission resources.
