Description

Transmission method and device of physical channel
Technical Field
The present application relates to the field of wireless communication technologies, and in particular, to a method and device for transmitting a physical channel.
Background
The NR system improves data transmission efficiency using a hybrid automatic repeat request (HARQ) mechanism. In the MAC layer, each cell has an HARQ entity, and the uplink and the downlink are independent. Each HARQ entity contains multiple parallel HARQ processes. If the data receiver feeds back the HARQ demodulation result to the sender as NACK after detecting the received data, the data sender can schedule and retransmit the HARQ process data, and the data receiver writes the HARQ process data into the HARQ cache region under the condition that the decoding of the HARQ process information fails, waits for the retransmitted data block of the HARQ process, and combines and decodes the data of the retransmitted data block and the data of the HARQ cache region. For each downlink HARQ process, the terminal equipment (UE) sends Acknowledgement (ACK) or non-acknowledgement (NACK) information to the base station according to the decoding result. The ACK and NACK information are collectively referred to as hybrid automatic repeat request acknowledgement information (HARQ-ACK). For each uplink HARQ process, the terminal equipment determines the HARQ-ACK state of the Data with the same HARQ process number at the previous time according to a New Data Indicator (NDI) in uplink scheduling information sent by the base station.
The coverage range of the ground-air communication and the satellite communication is wider, and if the HARQ process combining process based on HARQ-ACK feedback is still adopted in the ground-air communication and the satellite communication, the delay of service data transmission is greatly prolonged under the influence of the air propagation delay of HARQ-ACK information feedback and the delay of the retransmission process of HARQ process data. Such delay is unacceptable for some traffic data delay requirements. Therefore, in a communication system with long air propagation delay, such as low-altitude communication and satellite communication, HARQ-ACK feedback can be disabled. On the other hand, considering the reliability of important data such as system configuration information, the system also needs to reserve HARQ-ACK feedback of part of HARQ processes.
For de-enabling HARQ retransmission based on HARQ-ACK, the data scheduler cannot adjust the parameters of the retransmission scheduling based on the real-time demodulation result. In order to ensure the performance, multiple repeated transmissions can be pre-configured to improve the transmission performance.
In NR system design, if two or more channels on overlapping time resources need to be transmitted or received simultaneously by a terminal device, and the terminal device does not have the capability of transmitting or receiving the channels simultaneously, it is necessary to determine a channel with a higher priority level for transmission or reception according to the priority levels of the channels. If the channel for disabling the HARQ retransmission state based on HARQ-ACK is discarded due to a lower priority, the transport block carried by the channel cannot acquire the HARQ retransmission combining gain for the preset number of times, which may cause the reliability of the transport block to be reduced and affect the service quality of the terminal device.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more clear, the technical solutions of the present application will be clearly and completely described below with reference to the specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The invention provides a transmission method and equipment of a physical channel, which are mainly used for a system with larger propagation delay of a wireless link of ground-air communication or satellite communication.
The method divides the HARQ retransmission states corresponding to the PDSCH/PUSCH transmitted by each HARQ process into two types:
first type HARQ retransmission state: de-enabling HARQ retransmission based on HARQ-ACK;
second type HARQ retransmission state: HARQ retransmission based on HARQ-ACK is enabled.
For the HARQ transmission of the first type HARQ retransmission state, the data scheduler cannot adjust the retransmission scheduling parameters based on the real-time HARQ-ACK of the demodulation result. In order to ensure that the performance of the HARQ process in the first type of HARQ retransmission state is equivalent to the performance of the HARQ process in the second type of HARQ retransmission state, multiple repeated transmissions may be preconfigured for the HARQ process in the first type of HARQ retransmission state, so as to improve the transmission performance of the HARQ process.
For the same kind of channels, if the HARQ retransmission states are not distinguished, the first kind of HARQ retransmission states and the second kind of HARQ retransmission states use the same priority level, and a transport block in the first kind of HARQ retransmission states may not obtain the characteristic of HARQ retransmission combining gain due to the lower priority level, so that the reliability of the transport block in the first kind of HARQ retransmission states does not meet the requirement, and the service quality of the terminal device is affected.
Therefore, when two or more channels need to be sent or received simultaneously on the overlapped time resources, the method and the device have different priority levels aiming at the data transmission of the HARQ process in the first type of HARQ retransmission state and the HARQ process in the second type of HARQ retransmission state, can meet the service quality requirement of the terminal device, and improve the communication efficiency of the system.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a flow chart of an embodiment of the method of the present application.
The application provides a physical channel transmission method, which comprises the following steps of 101-103:
step 101, determining a channel set with an overlapping relationship;
in a set containing N (N is more than or equal to 2) channels, any one channel and at least one other channel have an overlapping relation in time;
the set is a set of uplink channels or a set of downlink channels, and in the set, any one channel and at least one other channel are overlapped in time; or there may be an overlap in time between all channels.
Preferably, the N channels are all PUSCHs and all PDSCHs or are partially PUSCHs and partially PUCCHs.
If the set is a set of uplink channels, the set includes at least one of a PUCCH and a PUSCH. Optionally, the PUCCH or PUSCH carries CSI information. Optionally, the PUSCH is dynamically scheduled or configuration-based.
The set includes at least one of a dynamically scheduled PDSCH and a semi-persistently scheduled PDSCH if the set is a set of downlink channels.
Step 102, determining the channel priority according to the HARQ retransmission state;
determining the priority of N channels, wherein for any 2 channels of the same type, the priority of the channel in the first type of HARQ retransmission state is higher than the priority of the channel in the second type of HARQ retransmission state;
the first type of HARQ retransmission state is to disable HARQ retransmission based on HARQ-ACK;
the second type of HARQ retransmission state is to enable HARQ retransmission based on HARQ-ACK;
the channel category comprises at least one of the following: a dynamically scheduled PDSCH; a semi-persistently scheduled PDSCH; a dynamically scheduled PUSCH; semi-persistently scheduled PUSCH.
Preferably, when the N channels are uplink channels, the types of the channels further include: and the PUSCH does not carry uplink control information.
Within the first set of channels, only M (M ≦ N) of the channels can be processed (transmitted or received) and the other N-M channels will be discarded, subject to the processing power of the terminal device. Or limited by the maximum transmit power of the terminal device, the terminal device has to reduce the transmit power of the partial channel. In this way, information carried by channels of the first set of channels that are dropped or have reduced transmit power will be affected.
In the embodiment of the present invention, the terminal device selects and processes (receives or transmits) M channels with higher priority levels from the N channels, the information carried in the M channels has a large influence on the service performance and the communication efficiency of the terminal device, and the processing capability or the transmission power of the terminal device is allocated to the channels with higher priority levels as much as possible, so that the service quality requirement of the terminal device can be ensured, and the system communication efficiency can be improved.
To achieve the above priority ordering of the channels, the priority between the channels should comply with at least one of the following priority rules:
priority 1 rule: the priority of the channel in the first type of HARQ retransmission state is higher than that of the channel in the second type of HARQ retransmission state;
in one embodiment of the application, the priority of the semi-persistently scheduled channel of the first type of HARQ retransmission state is higher than the priority of the dynamically scheduled channel of the second type of HARQ retransmission state.
For the PDSCH or the PUSCH without the uplink control information, the retransmission scheduling strategies corresponding to the two HARQ retransmission states are different, the available HARQ combining gain is also different, and the available data transmission target performance may also be different for the two modes. For the first type of HARQ retransmission state, the network device may have completed all K times of repeated transmission scheduling for the transport block before acquiring that the demodulation result of the PUSCH/PDSCH is ACK/NACK. The network device expects that the K PUSCH/PDSCH repeated transmissions can meet the target demodulation performance for the corresponding data block. If the PUSCH/PDSCH transmission is discarded or the transmission power is reduced in the first type HARQ retransmission state, the network equipment cannot make the performance reach the target requirement by scheduling the retransmission of the related transport block immediately. Particularly in a communication system with larger air propagation delay, such as satellite communication or low-altitude communication, the network equipment schedules the PUSCH/PDSCH for K times through a single PDCCH, so that the service transmission delay caused by scheduling data retransmission based on HARQ-ACK feedback can be avoided. If the target performance of the transport block is not satisfied due to the fact that part of the K repeated transmissions are discarded due to overlapping with other channels or the transmission power is reduced, if the network device reschedules the retransmission of the transport block, a large propagation delay effect is experienced, and the delay characteristic of the transport block cannot meet the requirement. For the second type HARQ retransmission state, the network device may determine whether to initiate retransmission scheduling for the corresponding transport block and determine the scheduled retransmission resource by whether the demodulation result of the PUSCH/PDSCH is ACK or NACK. And for the PUSCH/PDSCH which is not correctly demodulated, determining a scheduling strategy for retransmitting the PUSCH/PDSCH according to the target service performance and the current demodulation result, and ensuring that the transmission block reaches the preset target demodulation performance after K times of repeated transmission. The performance requirement of the transport block transmitted by the PUSCH/PDSCH using the second type HARQ retransmission state can also bear the data transmission delay brought by retransmission scheduling. Therefore, the priority of the channel in the first type HARQ retransmission state is higher than that of the channel in the second type HARQ retransmission state, so that the reliability and the time delay characteristic of data transmission in the first type HARQ retransmission state can be ensured, and the service quality requirement of the terminal equipment can be met.
Priority rule 2: the priority of the dynamically scheduled channel class is higher than that of the semi-persistently scheduled channel class.
It should be noted that the priority rules described above may be used in combination to determine M channels with higher priority among the N channels. Take the first set of channels as downlink channels as an example. The PDSCH channel is divided into a dynamically scheduled PDSCH and a semi-persistently scheduled PDSCH. The dynamically scheduled PDSCH has two types of HARQ retransmission states, namely a first type of HARQ retransmission state and a second type of HARQ retransmission state, and the semi-persistent scheduled PDSCH also has two types of HARQ retransmission states, namely a first type of HARQ retransmission state and a second type of HARQ retransmission state.
When the 1 st priority rule is applied first and the 2 nd priority rule is applied again, that is, when determining the priority order of the channels in the first channel set, the following rules are applied: firstly, determining the priority of the HARQ retransmission state according to whether the HARQ retransmission state is a first type HARQ retransmission state or a second type HARQ retransmission state, then determining the priority of each PDSCH in the first type HARQ retransmission state according to the dynamic scheduling or the semi-persistent scheduling of each PDSCH, and determining the priority of each PDSCH in the second type HARQ retransmission state according to the dynamic scheduling or the semi-persistent scheduling of each PDSCH. I.e. the priority of the channels in the first set of channels satisfies:
the channel dynamically scheduled in the first type HARQ retransmission state > the channel semi-persistently scheduled in the first type HARQ retransmission state > the channel dynamically scheduled in the second type HARQ retransmission state > the channel semi-persistently scheduled in the second type HARQ retransmission state. By adopting the priority level determination mode, no matter whether the channel is dynamically scheduled or semi-continuously scheduled, the transmission of the channel in the first type of HARQ retransmission state is preferentially not lost or the sending power is not reduced, so that the problem that the channel in the HARQ retransmission state based on HARQ-ACK is discarded due to the lower priority and the transmission block carried by the channel cannot acquire the HARQ retransmission combination gain of the preset number of times can be avoided. The reliability of the transmission block is improved, and the service quality of the terminal equipment is guaranteed.
When the 2 nd priority rule is applied first and the 1 st priority rule is applied again, that is, when determining the priority order of the channels, the following rule is adopted: firstly, determining the priority of PDSCH according to whether the PDSCH belongs to dynamic scheduling or semi-persistent scheduling, then determining the priority of each PDSCH dynamically scheduled according to whether the HARQ retransmission state of each PDSCH is a first-class HARQ retransmission state or a second-class HARQ retransmission state, and determining the priority of each PDSCH semi-persistent scheduling according to whether the HARQ retransmission state of each PDSCH is the first-class HARQ retransmission state or the second-class HARQ retransmission state. The priority relationship between the channels is as follows:
channel under dynamically scheduled first type HARQ retransmission state > channel under dynamically scheduled second type HARQ retransmission state > channel under semi-persistent scheduled first type HARQ retransmission state > channel under semi-persistent scheduled second type HARQ retransmission state. By adopting the priority level determination mode, the requirement that the transmission of the dynamic scheduling channel is not discarded or the transmission power is reduced is met preferentially. Secondly, in a plurality of channels with the same scheduling mode, the transmission of the channel is not discarded or the transmission power is not reduced under the condition that the first type HARQ retransmission state is preferentially met, and the condition that the dynamically scheduled channel is influenced by the overlapping transmission of the semi-persistent scheduling channel and is forced to be discarded or the transmission power is reduced can be avoided. And further, in the channels with the same scheduling mode, the problem that the channel which can enable the HARQ retransmission state based on the HARQ-ACK is discarded or the sending power is reduced due to the lower priority is ensured, and further, the transmission block carried by the channel cannot acquire the HARQ retransmission combination gain with the preset times is solved. The reliability of the transmission block is improved, and the service quality of the terminal equipment is guaranteed. Thus, the combined use of the 1 st priority rule and the 2 nd priority rule limits the 1 st priority rule to the same type of channel.
Priority rule 3: and the priority of the uplink channel in the first type of HARQ retransmission state is not lower than the uplink channel carrying CSI and not carrying HARQ-ACK.
In the embodiment of the application, the priority of the PUSCH in the first type of HARQ retransmission state is higher than or equal to the PUSCH which carries CSI and does not carry HARQ-ACK in the second type of HARQ retransmission state in the N channels; andor: and the priority of the PUSCH in the first type of HARQ retransmission state is higher than or equal to the PUCCH which carries CSI and does not carry HARQ-ACK in the N channels.
The CSI information represents the state information of the downlink channel measured by the terminal device, and the terminal device feeds this information back to the network device, which is beneficial for the network device to accurately and effectively schedule the wireless resources for downlink data transmission of the terminal device. In the existing system design, the accuracy of downlink data scheduling is ensured by sacrificing the PUSCH performance which does not carry uplink control information. That is, the priority of the PUSCH/PUCCH carrying CSI and not carrying HARQ-ACK is higher than that of the PUSCH not carrying uplink control information. In this way, the PUSCH carrying no uplink control information will likely be dropped as a low priority channel or transmit power reduced. The dropped or reduced transmit power PUSCH may correspond to a first type of HARQ retransmission state and may also correspond to a second type of HARQ retransmission state. If the PUSCH performance of the second type HARQ retransmission state affected by the processing capability of the terminal device or the maximum transmission power limit of the terminal device can be improved by initiating retransmission scheduling of a corresponding transport block, the prior art sets the priority of the PUSCH/PUCCH carrying CSI and not carrying HARQ-ACK to be higher than that of the PUSCH not carrying uplink control information, so that the transmission performance of the PUSCH is not greatly affected. However, if the PUSCH in the first type HARQ retransmission state is affected by the processing capability of the terminal device or the maximum transmission power limit of the terminal device, considering a large propagation delay effect, the network device schedules the transmission block for retransmission, which may result in that the delay characteristic of the transmission block cannot meet the requirement, and the effect of dropping or reducing the transmission power on the PUSCH in the first type HARQ retransmission state in the first channel set is large. Therefore, in the scheme of the embodiment, the priority of the channel in the first type of HARQ retransmission state is configured to be higher than or equal to the PUSCH carrying the CSI and not carrying the HARQ-ACK/the PUCCH carrying the CSI and not carrying the HARQ-ACK, which is beneficial to ensuring the service quality requirement of the PUSCH in the first type of HARQ retransmission state, and improving the communication efficiency of the system.
The priority rule is a rule applied when M channels are determined among N channels, but the priority rule for determining M channels among N channels is not limited to this, and may include other rules. For example, when all channels in the set are uplink channels, the priority of the physical random access channel is higher than the priority of a PUCCH carrying HARQ-ACK/SR (Scheduling request)/LRR (link recovery request) and the priority of a PUSCH carrying HARQ-ACK; PUCCH and PUSCH have higher priority than SRS (Sounding Reference Signal) and the like.
And 103, performing transceiving processing on the N channels according to the channel priority, and discarding or reducing the channel power with low priority.
Receiving M channels (M is less than or equal to N) from N channels according to the priority, and discarding other N-M channels; or, according to the priority, sending M channels in the N channels, and discarding other N-M channels; or, the actual transmission power of the N channels is determined according to the priority, the channel power with low priority is reduced preferentially, and the total transmission power of the N channels is reduced.
Fig. 2 is a flowchart of an embodiment of a method of the present application for a network device.
The method of any one embodiment of the first aspect of the present application, for a network device, includes the following steps 201-204:
step 201, the network device determines at least one set in at least one time unit;
specifically, a first channel set is determined, any one of the first channel set overlaps with at least one other channel in time, the first channel set comprises N channels, and N is greater than 2;

Optionally, the position and length of the time unit are preset, for example, the time unit is a time slot.

Based on the first configuration information, the network device can determine the priority between the channel in the first type HARQ retransmission state and the PUSCH carrying CSI/PUCCH carrying CSI according to the scheduling strategy and the service performance requirement of the HARQ retransmission state of the PUSCH, so that the service quality requirement and the scheduling flexibility of the terminal device are ensured, and the communication quality and the communication efficiency of the system are improved.

Fig. 3 is a flowchart of an embodiment of the method of the present application for a terminal device.
The method according to any one of the embodiments of the first aspect of the present application, applied to a terminal device, includes the following steps:
step 301, the terminal device determines at least one set in at least one time unit;
determining a first channel set, wherein any one of the first channel set is overlapped with at least one other channel in time, the first channel set comprises N channels, and N is more than or equal to 2;
the terminal device determines that the first set of channels may be completed by receiving configuration and/or scheduling information of the network device. The first channel set is a set of uplink channels or a set of downlink channels, and in the first channel set, any one channel and at least one other channel are overlapped in time; or there may be an overlap in time between all channels. The first set of channels includes at least one of a PUCCH and a PUSCH if the first set of channels is a set of uplink channels. Optionally, the PUCCH or PUSCH carries CSI information. Optionally, the PUSCH is dynamically scheduled or configuration-based. The first set of channels includes at least one of a dynamically scheduled PDSCH and a semi-persistently scheduled PDSCH if the first set of channels is a downlink set of channels.
Step 302, the terminal device receives configuration information and determines a priority rule;
the priority level may be determined by the terminal device through first configuration information.
Step 303, the terminal device determines the channel priority in the set;
in the embodiment of the invention, the terminal equipment selects and processes (receives or sends) M channels with higher priority levels in the channels, the information carried in the M channels has larger influence on the service performance and the communication efficiency of the terminal equipment, and the processing capacity or the sending power of the terminal equipment is distributed to the channels with higher priority levels as much as possible, so that the service quality requirement of the terminal equipment can be ensured, and the communication efficiency of the system is improved.
The priority level includes at least one of:
the priority of the channel in the first type of HARQ retransmission state is higher than that of the channel in the second type of HARQ retransmission state; the first type of HARQ retransmission state is to enable HARQ retransmission based on HARQ-ACK, and the second type of HARQ retransmission state is to enable HARQ retransmission based on HARQ-ACK;
the priority of the channel in the first type HARQ retransmission state is higher than or equal to the PUSCH which carries CSI and does not carry HARQ-ACK;
the priority of the channel in the first type of HARQ retransmission state is higher than or equal to the PUCCH carrying CSI and not carrying HARQ-ACK.
Optionally, the terminal device determines the priority level by receiving the first configuration information.
Optionally, the priority level further includes: channel in first-class HARQ retransmission state of dynamic scheduling > channel in second-class HARQ retransmission state of dynamic scheduling > channel in first-class HARQ retransmission state of semi-persistent scheduling > channel in second-class HARQ retransmission state of semi-persistent scheduling
Optionally, the priority level further includes: the channel dynamically scheduled in the first type HARQ retransmission state is more than the channel semi-persistently scheduled in the first type HARQ retransmission state, more than the channel dynamically scheduled in the second type HARQ retransmission state, and more than the channel semi-persistently scheduled in the second type HARQ retransmission state.
The priority of the channel in the first type HARQ retransmission state in the first channel set is higher than the priority of the channel in the second type HARQ retransmission state, so that the reliability and the time delay characteristic of data transmission in the first type HARQ retransmission state can be ensured, and the service quality requirement of the terminal equipment can be met.
And step 304, the terminal equipment receives the PDSCH and sends the PUSCH or PUCCH according to the priority.
Within the first set of channels, only M (M ≦ N) of the channels can be processed (transmitted or received) and the other N-M channels will be discarded, subject to the processing power of the terminal device. Or limited by the maximum transmit power of the terminal device, the terminal device has to reduce the transmit power of the partial channel. In this way, information carried by channels of the first set of channels that are dropped or have reduced transmit power will be affected.
Therefore, the terminal equipment determines to receive M (M is less than or equal to N) channels in the N channels according to the priority level; or determining to transmit M (M is less than or equal to N) channels in the N channels according to the priority level; or determining the transmission power of the N channels according to the priority level.
The priority level is used to determine that M (M ≦ N) of the N channels are received, including dropping other N-M channels.
The priority level is used to determine that transmitting M (M ≦ N) of the N channels includes dropping the N-M channels.
The priority level is used for determining the actual transmission power of the N channels, the sum of the initial transmission power of the N channels and the initial transmission power of L (L is larger than or equal to 0) basic channels is larger than the maximum transmission power of the terminal equipment, the sum of the actual transmission power of the N channels and the initial transmission power of the L (L is larger than or equal to 0) basic channels is not larger than the maximum transmission power of the terminal equipment, and the priority of the L basic channels is higher than that of the N channels.
After the priority levels of the N channels are determined, if the first channel set is a downlink channel, M (M is less than or equal to N) channels with higher priority in the N channels are determined to be received according to the priority levels, and other N-M channels are discarded. And if the first channel set is an uplink channel, determining to transmit M (M is less than or equal to N) channels with higher priority in the N channels according to the priority level, and discarding the other N-M channels. Or if the first channel set is an uplink channel, determining the transmission power of the N channels according to the priority level. And if the sum of the initial transmission power of the N channels and the initial transmission power of L (L is more than or equal to 0) basic channels determined according to the power adjustment indication and the power adjustment strategy of the network equipment is greater than the maximum transmission power of the terminal equipment, wherein the priority of the L basic channels is higher than that of the N channels in the first channel set. If the sum of the initial transmission power of the N channels and the initial transmission power of the L basic channels is larger than the maximum transmission power of the terminal equipment, the terminal equipment reduces the transmission power of the channel with lower priority level in the N channels and preferentially meets the transmission power of the channel with higher priority level. Assuming that the priority levels of the N channels are classified into J levels, the priority level of the ith level is higher than the priority level of the jth level, i < J, then the actual transmission power of the ith channel is preferentially ensured to be equal to the initial transmission power, if the sum of the actual transmission power of the level 1-i channels and the initial transmission power of the L fundamental channels is less than the maximum transmission power of the terminal device, if the sum of the actual transmission power of the 1 st to i +1 th level channels and the initial transmission power of the L basic channels is greater than the maximum transmission power of the terminal device, the actual transmit power of the ith level channel is equal to its initial transmit power, the actual transmit power of the (i + 1) th level channel is seen to be w times the initial transmit power, and enabling the sum of the actual transmission power of the 1 st-i +1 th level channel and the initial transmission power of the L basic channels not to be larger than the maximum transmission power of the terminal equipment.
