In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings that are needed in the embodiments of the present invention will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and other drawings may be obtained according to these drawings without inventive effort to a person skilled in the art.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application described herein may be capable of operation in sequences other than those illustrated or described herein, for example. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The wireless communication system of the embodiment of the invention comprises a terminal and network equipment. The terminal may also be referred to as a terminal Device or a User Equipment (UE), and the terminal may be a terminal-side Device such as a mobile phone, a tablet (Tablet Personal Computer), a Laptop (Laptop Computer), a personal digital assistant (Personal Digital Assistant, PDA), a mobile internet Device (Mobile Internet Device, MID), a Wearable Device (weardable Device), or a vehicle-mounted Device, which is not limited to a specific type of the terminal in the embodiment of the present invention. The network device may be a base station or core network, which may be a 5G or later version of a base station (e.g., a gNB, 5G NR NB, etc.), or a base station in other communication systems (e.g., an eNB, WLAN access point, or other access point, etc.), which may be referred to as a node B, an evolved node B, an access point, a base transceiver station (Base Transceiver Station, BTS), a radio base station, a radio transceiver, a basic service set (Basic Service Set, BSS), an extended service set (Extended Service Set, ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, or some other suitable terminology in the field, provided that the same technical effect is achieved, not limited to a particular technical vocabulary.
It should be noted that the embodiments of the present invention are applicable to MBMS (Multimedia Broadcast and Multicast Service, multimedia broadcast multicast service) or MBS (Multicast Broadcast Service, broadcast multicast service) scenarios. For MBMS or MBS scenarios, the corresponding information transmission manner may include, but is not limited to, the following two types:
transmission scheme 1: in MBSFN (Multimedia Broadcast multicast service Single Frequency Network, MBMS single frequency network) subframes, transmitted over PMCH (Physical Multicast Channel ). Wherein the control information may be transmitted through system information (e.g., SIB 13) and MCCH (Multicast Control Channel, broadcast control channel), and the data may be transmitted through MTCH (Multicast Traffic Channel, broadcast traffic channel).
Transmission method 2: PDSCH (Physical Downlink Shared Channel ) scheduled by PDCCH (Physical Downlink Control Channel) is transmitted. Wherein the control information may be transmitted through system information (e.g., SIB 20) and SC-MCCH (Single Cell Multicast Control Channel, single cell broadcast control channel), and the data may be transmitted through SC-MTCH (Single Cell Multicast Traffic Channel, single cell broadcast traffic channel). The SC-MCCH may be transmitted through PDSCH scheduled by an SC-RNTI (Single Cell RNTI, single Cell RNTI (Radio Network Temporary Identity, radio network temporary identity)) PDCCH, and the SC-MTCH may be transmitted through PDSCH scheduled by a G-RNTI (Group RNTI) PDCCH.
For the received MBS data, the UE may provide uplink feedback information (e.g., HARQ (Hybrid Automatic Repeat Request, hybrid automatic repeat request) ACK/NACK (acknowledgement/non-acknowledgement) feedback information). And the network device may decide whether to schedule retransmission according to the HARQ feedback information.
Referring to fig. 1, fig. 1 is a flowchart of a data receiving method according to an embodiment of the present invention, where the method is applied to a terminal, as shown in fig. 1, and the method includes the following steps:
step 101: after successful reception of the first data, the reception of the retransmission data of the first data is aborted.
In this embodiment, the first data may be MBMS data or MBS data. For the reception of MBMS data or MBS data, it is generally required that a plurality of UEs provide feedback information, where possible UEs receive the data successfully and some UEs do not receive the data successfully. And the network equipment retransmits the MBMS data or the MBS data according to the feedback information of the UE if the number of the UE which is not successfully received is relatively large. In the prior art, for a UE that successfully receives data, retransmission data is still to be received even if the MBMS data or MBS data has been successfully received, thereby increasing extra power consumption of the UE, resulting in large power consumption. Based on the embodiment, the UE that successfully receives the data will discard the reception of the retransmission data, thereby saving power consumption and reducing power consumption.
Alternatively, the first data may correspond to a HARQ process, such as data of the first HARQ process. The step 101 may include: the terminal gives up the reception of the retransmission data of the first HARQ process after successfully receiving the data of the first HARQ process.
Optionally, the retransmission data may be sent by a retransmission data corresponding to a specific identifier (for example, a C-RNTI, a G-RNTI, or a CS-RNTI).
It will be appreciated that 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 foregoing manner of discarding the reception of the retransmission data of the first data may be: discarding the retransmission data of the first data when the retransmission scheduling information of the first data is received; or, in the case of receiving the retransmission data of the first data, discarding the received retransmission data of the first data.
For example, after the terminal successfully receives the first data, if the retransmission scheduling information of the first data is received on the control channel, the terminal gives up to receive the retransmission data of the first data on the downlink channel which is correspondingly scheduled; or if the retransmission data of the first data is received directly on the scheduled downlink channel, discarding the retransmission data of the first data.
According to the data receiving method provided by the embodiment of the invention, after the terminal successfully receives the first data, the terminal can give up the reception of the retransmission data of the first data. Therefore, the terminal with successful data receiving can not receive the same retransmission data, so that the power consumption of the terminal is saved, and the power consumption is reduced.
In the embodiment of the present invention, according to the network configuration or protocol convention, after the terminal successfully receives the first data, the terminal may determine to discard the reception of the retransmission data based on any one of the following modes:
mode one
In this way, after successfully receiving the first data, the terminal empties the buffer data of the first data. The receiving of the retransmission data for discarding the first data specifically includes: based on the buffered data of the first data being empty, the reception of the retransmitted data of the first data is aborted.
As an alternative embodiment, the UE may empty the buffer data of the first HARQ process after successfully receiving the data of the first HARQ process (e.g., the MAC (Media Access Control, medium access control) PDU (Protocol Data Unit ) in the first HARQ process is successfully decoded); and if the buffer data of the first HARQ process is empty, discarding the reception of the retransmission data of the first HARQ process.
In one embodiment, the UE may receive data according to a configuration of the network device, e.g., the UE receives data of HARQ processes through PDSCH scheduled by G-RNTI PDCCH. If the UE successfully receives the data of the HARQ process, for the buffered data corresponding to the successfully received data, the UE may empty the buffered data, and for the subsequent retransmitted data, discard the reception of the retransmitted data based on the buffered data being empty.
Example 1.1: UE1-1 receives data of scheduling PDSCH through G-RNTI PDCCH at t1, and buffer memory of the data corresponds to HARQ process 1; if the data reception of the HARQ process 1 of the UE1-1 is successful, the UE1-1 empties the buffer corresponding to the HARQ process 1. At time t2, UE1-1 receives data of PDSCH scheduled by G-RNTI or C-RNTI PDCCH, the data is retransmission data of HARQ process 1, at this time, UE1-1 judges that buffer data of HARQ process 1 is empty, and UE1-1 discards the received data of PDSCH scheduled by G-RNTI or C-RNTI PDCCH. If the UE1-1 determines that the buffered data of the HARQ process 1 is not empty, the UE1-1 continues to receive the G-RNTI or the PDSCH data scheduled by the C-RNTI PDCCH, and performs combining decoding on the retransmission data and the data buffered in the previous HARQ process 1.
Example 1.2: the UE1-2 receives data on semi-persistent downlink resources (e.g., 1 PDSCH received every 10 ms) according to the network side configuration. Assuming that UE1-2 successfully receives PDSCH data at time t3, the buffer corresponding to the data is HARQ process 2, UE1-2 empties the buffer corresponding to HARQ process 2. If the UE1-2 receives the data of the PDSCH scheduled by the G-RNTI or the C-RNTI at the time of t3+5ms, the data is the retransmission data of the HARQ process 2, and at this time, the buffer data of the HARQ process 2 judged by the UE1-2 is empty, the UE1-2 discards the data reception of the PDSCH scheduled by the G-RNTI or the C-RNTI PDCCH.
Example 1.3: the network device configures UE1-3 to receive the same data in 2 adjacent time slots (slots) (e.g., slot-1 is new transmission data with rv0 and slot-2 is retransmission data with rv 2), corresponding to the same HARQ process 3. If the data reception of the UE1-3 in slot-1 is successful, the buffer corresponding to the HARQ process 3 can be emptied. Further, after the UE1-3 determines that the buffer data of the HARQ process 3 is empty, the UE may discard the data reception of the PDSCH of the slot-2.
Mode two
In the second mode, after the terminal successfully receives the first data, the terminal adds the marking information; the tag information is used for indicating that the first data has been successfully received, and the adding position of the tag information can be selected based on actual requirements, for example, the tag information is added to the data buffer. The receiving of the retransmission data for discarding the first data specifically includes: based on the tag information, the reception of the retransmission data of the first data is aborted.
As an alternative embodiment, after successfully receiving the data of the first HARQ process (e.g., the MAC PDU in the first HARQ process is successfully decoded), the UE may add flag information for indicating that the first data has been successfully received at a preset location; and if the retransmission information of the first HARQ process is received subsequently, based on the marking information, discarding the reception of the retransmission data of the first HARQ process.
In one embodiment, the UE receives data according to a configuration of the network device, e.g., the UE receives data of HARQ processes through PDSCH scheduled by G-RNTI PDCCH. If the UE successfully receives the data of the HARQ process, flag information for indicating that the data has been successfully received may be added at a preset location, and for the subsequent retransmission data, the reception of the retransmission data is aborted based on the flag information.
Example 2.1: the UE2-1 receives data of the PDSCH scheduled by the G-RNTI PDCCH at the time t4, and the buffer memory of the data corresponds to the HARQ process 4; if the data reception of the HARQ process 4 of the UE2-1 is successful, the UE2-1 adds flag information for indicating that the data has been successfully received at a preset location. And the UE2-1 receives the data of the PDSCH scheduled by the G-RNTI or the C-RNTI PDCCH at the time t5, wherein the data is the retransmission data of the HARQ process 4, and the UE2-1 discards the received data of the PDSCH scheduled by the G-RNTI or the C-RNTI PDCCH based on the marking information. If the UE2-1 does not obtain the marking information and judges that the buffered data of the HARQ process 4 is not successfully received, the UE2-1 continues to receive the G-RNTI or the PDSCH scheduled by C-RNTI PDCCH, and performs merging decoding on the retransmission data and the data buffered in the previous HARQ process 4.
Example 2.2: the UE2-2 receives data on semi-persistent downlink resources (e.g., 1 PDSCH received every 10 ms) according to the network side configuration. Assuming that UE2-2 successfully receives PDSCH data at time t6, the buffer corresponding to the data is HARQ process 5, UE2-2 adds flag information for indicating that the data has been successfully received at a preset location. If the UE2-2 receives the data of the PDSCH scheduled by the G-RNTI or the C-RNTI at the moment of t6+5ms, the data is the retransmission data of the HARQ process 5, and the UE2-2 abandons the data reception of the PDSCH scheduled by the G-RNTI or the C-RNTI PDCCH based on the marking information.
Example 2.3: the network device configures UE2-3 to receive the same data in 2 adjacent time slots (slots) (e.g., slot-3 is the newly transmitted data and rv0, and slot-4 is the retransmitted data and rv 2), corresponding to the same HARQ process 6. If the data reception of the UE2-3 at slot-3 is successful, the data reception of the PDSCH of slot-4 is abandoned.
In an embodiment of the present invention, the successfully receiving the first data may include any one of the following:
after the data is received, the independent decoding is successful (for example, the data is new transmission data of the HARQ process 1, and the UE decodes the new transmission data of the HARQ process 1 successfully);
the received data is successfully decoded after being combined with the same data buffered before the present time (for example, the received data is the retransmission data of the HARQ process 1, and the UE successfully decodes the retransmission data of the HARQ process 1 after being combined with the buffered data of the HARQ process 1).
Optionally, the sending manner of the first data may include any one of the following:
a dynamically scheduled data transmission mode (e.g., data transmission of PDSCH scheduled by C-RNTI or G-RNTI PDCCH);
semi-persistent data transmission scheme (e.g., transmission of PDSCH of SPS (Semi-Persistent Scheduling).
In the embodiment of the present invention, according to the network configuration or protocol convention, after receiving the first data (such as MBS data), the terminal needs to send feedback information to the network device. And for the retransmission data of the discarded first data, the transmission of the feedback information corresponding to the retransmission data (for example, the PDSCH of the retransmission data discarded by the UE) may be discarded according to the network configuration or protocol convention.
Optionally, after foregoing discarding the receiving of the retransmission data of the first data, the method further includes: giving up the transmission of feedback information corresponding to the retransmission data; the feedback information may be any of the following types: HARQ feedback, CSI (Channel State Information ) feedback.
In an embodiment, in the case that the type of the feedback information is HARQ feedback, the feedback information corresponding to the discard may be any one of the following:
feedback information successfully received by HARQ; for example, ACK feedback is not sent for HARQ, but is needed to be sent for HARQ NACK;
feedback information that HARQ did not successfully receive; for example, NACK feedback is not transmitted for HARQ, but is required to be transmitted for HARQ ACK feedback.
In another embodiment, in the case that the type of the feedback information is CSI feedback, the feedback information that is discarded correspondingly may be any one of the following:
periodic CSI feedback; for example, no periodic CSI feedback is transmitted, but aperiodic CSI feedback needs to be transmitted;
aperiodic CSI feedback; for example, no transmission is required for aperiodic CSI feedback, but transmission is required for periodic CSI feedback.
