It should be pointed out that the embodiments of the present invention are applicable to scenarios of MBMS (Multimedia Broadcast and Multicast Service, multimedia broadcast multicast service) or MBS (Multicast Broadcast Service, broadcast multicast service). For MBMS or MBS scenarios, the corresponding information sending methods may include but not limited to the following two:

Sending mode 1: sending through PMCH (Physical Multicast Channel, physical multicast channel) in MBSFN (Multimedia Broadcast multicast service Single Frequency Network, MBMS single frequency network) subframe. Wherein, the control information may be sent through system information (eg, SIB13) and MCCH (Multicast Control Channel, broadcast control channel), and data may be sent through MTCH (Multicast Traffic Channel, broadcast traffic channel).

Transmission mode 2: transmission through a PDSCH (Physical Downlink Shared Channel, physical downlink shared channel) scheduled by a PDCCH (Physical Downlink Control Channel, physical downlink control channel). Among them, the control information can be sent through system information (eg, SIB20) and SC-MCCH (Single Cell Multicast Control Channel, single cell broadcast control channel), and data can be sent through SC-MTCH (Single Cell Multicast Traffic Channel, single cell broadcast traffic channel) .

For the received MBS data, the UE will provide uplink feedback information (for example, HARQ (Hybrid Automatic Repeat Request, Hybrid Automatic Repeat Request) ACK/NACK (acknowledgement/non-acknowledgement) feedback information). The network device can decide whether to schedule retransmission according to the HARQ feedback information.

Please refer to FIG. 1. FIG. 1 is a flowchart of a data receiving method provided by an embodiment of the present invention. The method is applied to a terminal. As shown in FIG. 1, the method includes the following steps:

Step 101: After the first data is successfully received, the reception of the retransmission data of the first data is abandoned.

In this embodiment, the first data may be MBMS data or MBS data. For the reception of MBMS data or MBS data, usually multiple UEs are required to provide feedback information. At this time, some UEs may receive the data successfully, and some UEs may not receive the data successfully. According to the feedback information from the UEs, if the number of UEs that fail to receive the received information is relatively large, the network device will retransmit the MBMS data or MBS data. In the prior art, for a UE that successfully receives data, even if the MBMS data or MBS data has been successfully received, it still needs to receive retransmission data, thereby increasing the extra power consumption of the UE, resulting in large power consumption. However, based on this embodiment, the UE that successfully receives data will give up receiving retransmitted data, thereby saving power consumption and reducing power consumption.

Optionally, the first data may correspond to a HARQ process, such as data of the first HARQ process. The above step 101 may include: after the terminal successfully receives the data of the first HARQ process, giving up receiving the retransmission data of the first HARQ process.

Optionally, the foregoing retransmission data sending manner may be retransmission data corresponding to a specific identifier (for example, C-RNTI, G-RNTI, or CS-RNTI).

Understandably, after successfully receiving the first data, the terminal may still receive retransmission information of the first data, such as retransmission scheduling information or retransmission data. The method of giving up the reception of the retransmission data of the first data may be: in the case of receiving the retransmission scheduling information of the first data, giving up receiving the retransmission data of the first data; or, after receiving the first data In the case of the retransmission data of the first data, the received retransmission data of the first data is discarded.

For example, after the terminal successfully receives the first data, if it receives the retransmission scheduling information of the first data on the control channel, it will give up receiving the retransmission data of the first data on the corresponding scheduled downlink channel; or, if The retransmission data of the first data is directly received on the scheduled downlink channel, and the retransmission data of the first data is discarded.

In the data receiving method of the embodiment of the present invention, after the terminal successfully receives the first data, it may give up receiving the retransmission data of the first data. In this way, the terminal that successfully receives the data can no longer receive the same retransmission data, thereby saving the power consumption of the terminal and reducing the power consumption.

In the embodiment of the present invention, according to the network configuration or protocol agreement, after the terminal successfully receives the first data, it may determine to abandon the reception of the retransmission data based on any of the following methods:

method one

In this way, after the terminal successfully receives the first data, it clears the cached data of the first data. The above abandoning the reception of the retransmission data of the first data specifically includes: abandoning the reception of the retransmission data of the first data based on the fact that the cached data of the first data is empty.

As an optional implementation manner, after the UE successfully receives the data of the first HARQ process (for example, the MAC (Media Access Control, media access control) PDU (Protocol Data Unit, protocol data unit) in the first HARQ process After successful decoding), the buffer data of the first HARQ process can be cleared; for the subsequent reception of the retransmission information of the first HARQ process, based on the fact that the buffer data of the first HARQ process is empty, the first HARQ process is abandoned. The process of receiving retransmitted data.

In one embodiment, the UE can receive data according to the configuration of the network device, for example, the UE receives the data of the HARQ process through the PDSCH scheduled by the G-RNT IP DCCH. If the UE successfully receives the data of the HARQ process, the UE can clear the buffered data corresponding to the successfully received data, and for the subsequent retransmitted data, based on the fact that the buffered data is empty, abandon the reception of the retransmitted data .

Example 1.1: UE1-1 receives the data of scheduling PDSCH through G-RNTI PDCCH at time t1, and the data cache corresponds to HARQ process 1; if the data of UE1-1’s HARQ process 1 is successfully received, UE1-1 clears the data The cache corresponding to HARQ process 1. At time t2, UE1-1 receives the data of PDSCH scheduled by G-RNTI or C-RNTI PDCCH, which is the retransmission data of HARQ process 1 data. At this time, UE1-1 judges that the cached data of HARQ process 1 is empty. , the UE1-1 discards the received data of the PDSCH scheduled by the G-RNTI or C-RNTI PDCCH. If UE1-1 judges that the cached data of HARQ process 1 is not empty, UE1-1 will continue to receive the data of the PDSCH scheduled by the G-RNTI or C-RNTI PDCCH, and compare the retransmitted data with the previous cached data in HARQ process 1. The data are merged and decoded.

Example 1.2: UE1-2 receives data in semi-persistent downlink resources (for example, receiving 1 PDSCH every 10 ms) according to the network side configuration. Assuming that UE1-2 successfully receives PDSCH data at time t3, and the buffer corresponding to the data is HARQ process 2, UE1-2 clears the buffer corresponding to HARQ process 2. If UE1-2 receives the data of PDSCH scheduled by G-RNTI or C-RNTI at the time of t3+5ms, the data is the retransmission data of HARQ process 2 data, the cache of HARQ process 2 judged by UE1-2 at this time If the data is empty, UE1-2 gives up receiving data on the PDSCH scheduled by the G-RNTI or C-RNTI PDCCH.

Example 1.3: The network device configures UE1-3 to receive the same data in two adjacent slots (for example, slot-1 uses rv0 for newly transmitted data, and slot-2 uses rv2 for retransmitted data), corresponding to the same HARQ process 3. If UE1-3 successfully receives the data in slot-1, the buffer corresponding to the HARQ process 3 may be cleared. Further, after the UE1-3 judges that the cached data of the HARQ process 3 is empty at the slot-2, it may give up receiving the data of the PDSCH of the slot-2.

way two

In the second method, after the terminal successfully receives the first data, it adds tag information; wherein, the tag information is used to indicate that the first data has been successfully received, and the location where the tag information is added can be selected based on actual needs, such as adding the tag information in the data cache. The foregoing abandoning the receiving of the retransmitted data of the first data specifically includes: abandoning the receiving of the retransmitted data of the first data based on the flag information.

As an optional implementation manner, after the UE successfully receives the data of the first HARQ process (for example, the MAC PDU in the first HARQ process is successfully decoded), it can add a message indicating that the first HARQ process has been successfully received at the preset position. Marking information of the data; if the retransmission information of the first HARQ process is subsequently received, based on the marking information, the reception of the retransmission data of the first HARQ process is abandoned.

In one embodiment, the UE receives data according to the configuration of the network device, for example, the UE receives the data of the HARQ process through the PDSCH scheduled by the G-RNT IP DCCH. If the UE successfully receives the data of the HARQ process, it may add marker information indicating that the data has been successfully received at a preset position, and for subsequent retransmitted data, based on the marker information, give up receiving the retransmitted data.

Example 2.1: UE2-1 receives the data of scheduling PDSCH through G-RNTI PDCCH at time t4, and the cache of the data corresponds to HARQ process 4; if the data of UE2-1's HARQ process 4 is successfully received, UE2-1 Sets the location to add flag information indicating that the data has been successfully received. UE2-1 receives PDSCH data scheduled by G-RNTI or C-RNTI PDCCH at time t5, the data is the retransmission data of HARQ process 4 data, then UE2-1 discards the received data based on the flag information Data of PDSCH scheduled by G-RNTI or C-RNTI PDCCH. If UE2-1 does not obtain the flag information and judges that the cached data of HARQ process 4 has not been successfully received, UE2-1 will continue to receive the data of the PDSCH scheduled by the G-RNTI or C-RNTI PDCCH, and combine the retransmitted data with the The data buffered in the previous HARQ process 4 is combined and decoded.

Example 2.2: UE2-2 receives data in semi-persistent downlink resources (for example, receiving 1 PDSCH every 10 ms) according to network side configuration. Assuming that UE2-2 successfully receives PDSCH data at time t6, and the cache corresponding to the data is HARQ process 5, UE2-2 adds flag information indicating that the data has been successfully received at a preset position. If UE2-2 receives the data of PDSCH scheduled by G-RNTI or C-RNTI at the time of t6+5ms, the data is the retransmission data of HARQ process 5 data, at this time, UE2-2 discards the data based on the flag information Data reception of PDSCH scheduled by G-RNTI or C-RNTI PDCCH.

Example 2.3: The network device configures UE2-3 to receive the same data in two adjacent slots (for example, slot-3 uses rv0 for newly transmitted data, and slot-4 uses rv2 for retransmitted data), corresponding to the same The HARQ process6. If the UE2-3 successfully receives the data in slot-3, it abandons the data reception of the PDSCH in slot-4.

In the embodiment of the present invention, the successful reception of the first data may include any of the following:

After the data is received this time, the independent decoding is successful (for example, this data is the newly transmitted data of HARQ process 1, and the UE successfully decodes the newly transmitted data of HARQ process 1);

The data received this time and the same data cached before this time are combined and decoded successfully (for example, the data received this time is the retransmission data of HARQ process 1, and the retransmission data of HARQ process 1 and the cached data of HARQ process 1 by the UE Decoding succeeds after merging).

Optionally, the above-mentioned sending method of the first data may include any of the following:

Data transmission mode of dynamic scheduling (for example, data transmission of PDSCH scheduled by C-RNTI or G-RNTI PDCCH);

A semi-persistent data transmission mode (for example, PDSCH transmission of SPS (Semi-Persistent Scheduling, semi-persistent scheduling)).

In the embodiment of the present invention, according to network configuration or agreement, after receiving the first data (such as MBS data), the terminal needs to send feedback information to the network device. For the retransmission data of the abandoned first data, the sending of the feedback information corresponding to the retransmission data (for example, the PDSCH of the retransmission data received by the UE giving up) may be abandoned according to network configuration or protocol agreement.

Optionally, after giving up the reception of the retransmission data of the first data, the method further includes: giving up sending the feedback information corresponding to the retransmission data; wherein, the type of the feedback information can be any of the following: HARQ Feedback, CSI (Channel State Information, channel state information) feedback.
