Background

Whereas PUCCH repetition transmission is a coverage problem that can be generally used to solve PUCCH. But currently the common PUCCH resources do not support PUCCH repetition transmission. Therefore, there is a need to implement a PUCCH repeated transmission method for a common PUCCH resource.

First, related concepts related to the embodiments of the present application will be described:

the Common PUCCH retransmission (retransmission) refers to PUCCH retransmission performed on a Common (Common) PUCCH resource, and may be PUCCH retransmission for feeding back Msg4 HARQ, or may be other PUCCH retransmission performed when a terminal cannot obtain a dedicated PUCCH resource, and the PUCCH format may be PUCCH format 1 or PUCCH format 0, or other PUCCH formats may not be excluded.

The Common PUCCH resource refers to a PUCCH resource commonly configured for multiple users or a Common PUCCH resource configured for each serving cell, and may be used by a terminal before a dedicated (configured) PUCCH resource is configured. The PUCCH on the Common PUCCH resource is sometimes also directly denoted as Common PUCCH.

The common PUCCH repeated transmission method provided in the embodiments of the present application is described in detail below by some embodiments and application scenarios thereof with reference to the accompanying drawings.

Fig. 2 is one of flow diagrams of a common PUCCH retransmission method provided in an embodiment of the present application. As shown in fig. 2, the method provided in this embodiment includes:

step 101, determining a first transmission time slot occupied by common PUCCH repeated transmission;

Step 102, based on the first transmission time slot, performing common PUCCH repeated transmission.

Specifically, the first transmission time slot may be a time domain resource determined based on the corresponding scheduling information or configuration information, that is, a time slot occupied by the common PUCCH repeated transmission; for example, the scheduling information or the configuration information may indicate a starting position of a time domain resource for common PUCCH retransmission and the number of symbols occupied per retransmission/non-retransmission.

The first transmission time slot may be N consecutive physical time slots, or N available time slots, N being a positive integer;

in case of common PUCCH repetition transmission based on physical slots, the repetition number may be counted based on physical slots, i.e., N physical slots are counted in the repetition number.

In case of common PUCCH repetition transmission based on available time slots, the number of repetitions may be counted based on the available time slots, i.e. only the available time slots may be counted in the number of repetitions.

For example, the number of repetitions may be default or preconfigured.

The method of the embodiment determines a first transmission time slot occupied by the common PUCCH repeated transmission; and carrying out the common PUCCH repeated transmission based on the first transmission time slot, thereby realizing the PUCCH repeated transmission on the common PUCCH resource and improving the receiving reliability of the common PUCCH.

Alternatively, step 101 may be implemented as follows:

and determining a first transmission time slot based on the counting type adopted by the terminal for carrying out the common PUCCH repeated transmission.

In some embodiments, common PUCCH repetition transmissions are transmitted on a physical slots (physical slots) basis, i.e., consecutive physical slots are used for PUCCH repetition, and these consecutive physical slots are all counted in a configured number of repetitions.

In some embodiments, common PUCCH repetition transmissions are transmitted based on available slots (available slots), i.e., only available slots are used for PUCCH repetition transmissions and these available slots are counted in a configured number of repetitions.

I.e. the terminal may determine the first transmission slot based on the type of count (which may also be referred to as slot type) of common PUCCH repeated transmission.

Optionally, when determining the first transmission slot, the count type is based on, for example, the following cases:

the counting type is a default physical time slot based repetition count; or alternatively, the first and second heat exchangers may be,

counting the repetition times based on the available time slots with the default counting type; or alternatively, the first and second heat exchangers may be,

based on the counting type adopted by the terminal for carrying out the common PUCCH repeated transmission, before determining the first transmission time slot, the method further comprises the following steps:

Receiving first indication information sent by network side equipment; the first indication information is used for indicating a counting type adopted by the terminal for carrying out the common PUCCH repeated transmission; the count type includes counting the number of repetitions based on physical time slots or based on available time slots.

That is, the counting type adopted by the terminal may be a counting type adopted by a protocol convention or a network side device configuration, for example, the counting type is a type indicated by the first indication information, and at this time, the counting type may be a counting of the repetition number based on a physical time slot or based on an available time slot, or the counting type may be a counting type adopted by a protocol convention or a default, for example, a counting of the repetition number based on a default physical time slot or a counting of the repetition number based on an available time slot. Alternatively, physical timeslots may be employed by default when the terminal does not have the capability to count based on available timeslots.

Optionally, if the count type is based on the physical time slot and the repetition count, the first transmission time slot is N consecutive time slots starting from the time domain resource starting position of the common PUCCH repetition transmission, where N is a positive integer.

The time domain resource of the common PUCCH repeated transmission may be indicated by scheduling information or configuration information of the network side device.

Optionally, if the repeated transmission is inter-slot repeated transmission, N is equal to the number of repetitions K, where K is a positive integer;

if the repeated transmission is repeated transmission in a time slot, N is equal to the number of time slots occupied by the repeated transmission time domain resource.

For example, the starting symbol is 10, and if each repetition occupies 4 symbols, and is repeated 8 times in total, the number of occupied slots is 3 (for example, one slot includes 14 symbols), that is, the number is obtained by rounding up (4×8+10)/14.

Optionally, the first indication information is sent by at least one of:

radio resource control (Radio Resource Control, RRC) signaling;

target downlink control information (Downlink Control Information, DCI) for scheduling a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) corresponding to the common PUCCH;

PDSCH corresponding to common PUCCH;

a target message;

DCI for scheduling the target message;

PUCCH resource set information;

physical random access channel (Physical Random Access Channel, PRACH) format.

Optionally, the target message includes at least one of: message 2, message 4, message B.

Optionally, the target message is a message in a random access procedure.

Specifically, whether the common PUCCH repeated transmission is based on an available slot or a physical slot may be determined by one or more of the following methods:

Indicated by RRC signaling; for example, at least one bit may be configured in the system message to indicate whether the common PUCCH repeated transmission is based on an available slot or a physical slot.

Alternatively, it may be assumed in this case that all terminals are equipped with an available slot-based capability such as PUCCH repetition or that all terminals supporting common PUCCH repetition are equipped with an available slot-based capability for common PUCCH repetition.

Or, PUCCH repeated transmission on all common PUCCH resources is based on available slot, and may be indicated in Msg2, msg4, msgB, or respective scheduling DCI, for example, by default, common PUCCH repeated transmission is based on physical slots.

Or, the PUCCH resource set information (resource set information before dedicated resource configuration) may be embodied, for example, by a table, for example, a modified PUCCH resource set (PUCCH resource set) table may be used, or an available slot-based common common PUCCH repetition may be supported using an independent PUCCH resource set table, i.e. for example, different tables may indicate different count types, or different fields in a table may indicate different count types.

Or, different PRACH format formats may correspond to different count types.

In the above embodiment, the counting type can be determined in different manners, so that the flexibility is high and the complexity is low.

Optionally, if the count type is based on the available time slots and the terminal uses a frequency band supporting unpaired spectrum (unpaired spectrum), the first transmission time slot is N available time slots starting from a time slot where a time domain resource starting position of the common PUCCH retransmission is located, N is a positive integer, and at least one of the following is satisfied:

the target symbol is an uplink symbol;

the target symbol is a flexible symbol and is not overlapped with the symbol occupied by the synchronous signal Block (Synchronization Signal/physical broadcast channel (PBCH Block, SSB);

the target symbol is not overlapped with the symbol occupied by the PRACH;

the target symbol does not overlap with the symbol occupied by the physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) used to transmit message a;

the target symbol does not overlap with the symbol occupied by the common search space (common search space);

the target symbol is not overlapped with the symbol occupied by the control resource set0 (CORESET 0);

and the target symbol is a symbol occupied by the first transmission time slot and is used for common PUCCH repeated transmission.

For example, when a symbol occupied by a certain slot overlaps with a downlink symbol, the slot is not an available slot. For example, when a symbol occupied by a certain slot overlaps a symbol occupied by an SSB, then the slot is not an available slot.

Wherein the target symbol is used for common PUCCH retransmission, for example, the common PUCCH retransmission occupies only the last 10 symbols of one slot, where the target symbol means that the 10 symbols satisfy the above condition, and the first 4 symbols of the slot may not actually satisfy the above condition.

Optionally, if the count type is based on the available time slots and the terminal uses a frequency band supporting paired spectrum (paired spectrum) or supplemental uplink spectrum (supplementary uplink band), the first transmission time slot is N available time slots starting from a time slot where a starting position of a time domain resource of a common PUCCH repeated transmission is located, N is a positive integer, and at least one of the following is satisfied:

the target symbol is not overlapped with the symbol occupied by the synchronous signal block SSB;

the target symbol is not overlapped with the symbol occupied by the PRACH;

the target symbol is not overlapped with the symbol occupied by the physical uplink shared channel PUSCH used for sending the message A;

The target symbol is not overlapped with the symbol occupied by the public search space;

the target symbol is not overlapped with the symbol occupied by the control resource set 0;

Optionally, the terminal has a capability of performing common PUCCH retransmission based on an available time slot, that is, has a capability of counting the number of repetitions based on the available time slot, that is, has a capability of performing common PUCCH retransmission using a count type of counting the number of repetitions based on the available time slot.

If the terminal based on the available time slot count is not supported, the terminal based on the physical time slot count may be supported by default, and no indication information is needed to indicate which counting mode is adopted, or the indication of the first indication information may be ignored.

In the case of counting the number of repetitions based on the available slots, the first transmission slot is N available slots starting from a slot where a time domain resource start position of the common PUCCH repetition transmission is located, N is a positive integer, a time domain resource of the time domain common PUCCH repetition transmission is a resource indicated based on scheduling information or configuration information, and the N slots may be consecutive or non-consecutive.

For example, the terminal determines N time slots of common PUCCH repeated transmission of message 4/message B according to time domain information scheduled by downlink DCI of scheduling message 4/message B or time domain information scheduled by message B; the time domain information may include: information of time domain resources for common PUCCH repetition transmission.

For unpaired spectrum:

The UE determines N slots for a PUCCH repetition transmission of Msg4/MsgB HARQ-ACK,based on tdd-UL-DL-ConfigurationCommon and ssb-PositionsInBurst,and the time domain information scheduled by downlink DCI for scheduling Msg4/MsgB or by MsgB.

A slot is not counted in the number of N slots for a PUCCH repetition transmission of Msg4/MsgB HARQ-ACK,if at least one of the symbols indicated in the slot scheduled for PUCCH repetition transmission of Msg4/MsgB HARQ-ACK overlaps with a DL symbol in dicated by tdd-UL-DL-ConfigurationCommon if provided,or a symbol of an SS/PBCH block with index provided by ssb-PositionsInBurst.

For paired spectrum and SUL band:

The UE determines N consecutive slots for a PUCCH repetition transmission of Msg4/MsgB HARQ-ACK,based on the time domain information scheduled by corresponding downlink DCI or MsgB.

For intra-slot repetition:

For unpaired spectrum:

The UE determines one slots for a PUCCH intra-slot repetition transmission of Msg4/MsgB HARQ-ACK with K repetitions,based on tdd-UL-DL-ConfigurationCommon and ssb-PositionsInBurst,and the time domain information scheduled by downlink DCI for scheduling Msg4/MsgB or by MsgB.

A slot is not counted in the number of K repetitions for a PUCCH repetition transmission of Msg4/MsgB HARQ-ACK,if at least one of the symbols indicated in the slot scheduled for PUCCH repetition transmission of Msg4/MsgB HARQ-ACK overlaps with a DL symbol indicated by tdd-UL-DL-ConfigurationCommon if provided,or a symbol of an SS/PBCH block with index provided by ssb-PositionsInBurst.

For paired spectrum and SUL band:

The UE determines consecutive symbols consisting of K repetitions for a PUCCH intra-slot repetition transmission of Msg4/MsgB HARQ-ACK,based on the time domain information scheduled by corresponding downlink DCI or MsgB.

in the above embodiment, the available time slots are determined by the above scheme, so that the number of repetition times that can be supported by the common PUCCH is increased to a greater extent, and the receiving reliability of the common PUCCH is further improved.

Optionally, the first transmission time slot includes: the first slot for common PUCCH repetition transmission.

Specifically, in some embodiments, the first time slot scheduled by the network side device for the first common PUCCH repetition, i.e., the first time slot for the common PUCCH retransmission, satisfies one or more of the following rules:

alternatively, the time slot may be an available slot or a non-available slot;

optionally, the network side device needs to ensure that the slot is an available slot, and the terminal does not expect the slot to be a non-available slot.

Alternatively, step 102 may be implemented as follows:

executing the common PUCCH repeated transmission under the condition that the common PUCCH repeated transmission collides with the target uplink channel transmission and the first condition is met;

in case that the common PUCCH repeated transmission collides with the target uplink channel transmission, performing the common PUCCH repeated transmission; or alternatively, the first and second heat exchangers may be,

discarding the common PUCCH repeated transmission under the condition that the common PUCCH repeated transmission collides with the target uplink channel transmission; or alternatively, the first and second heat exchangers may be,

Under the condition that the common PUCCH repeated transmission conflicts with the target uplink channel transmission and the first condition is not met, the terminal discards the common PUCCH repeated transmission;

discarding the common PUCCH repeated transmission under the condition that the terminal uses a frequency band supporting unpaired frequency spectrum (unpaired spectrum) and the common PUCCH repeated transmission collides with the target downlink channel transmission;

discarding the common PUCCH repeated transmission under the condition that the common PUCCH repeated transmission does not meet a second condition when the terminal is in a half duplex mode;

and discarding the common PUCCH repeated transmission under the condition that the terminal is in the half duplex mode.

In particular, the above-mentioned collision refers to that there is an overlap, e.g. a full or partial overlap, of time domain resources.

In the case that the common PUCCH repeated transmission collides with the target uplink channel transmission, the common PUCCH repeated transmission may be preferentially performed, which means that the transmission of the target uplink channel is discarded or the target uplink channel is not transmitted;

discarding the common PUCCH repeated transmission under the condition that the common PUCCH repeated transmission conflicts with the target uplink channel transmission, and performing the target uplink channel transmission at the moment;

in the case where the common PUCCH repeated transmission collides with the target downlink channel transmission, the common PUCCH repeated transmission is discarded, at which time the target downlink channel transmission may be performed.

In case of collision of the common PUCCH repeated transmission with the target uplink channel transmission, whether drop common PUCCH repetition depends on whether the first condition is met, and if the first condition is not met, common PUCCH repetition is discarded;

optionally, the first condition includes at least one of:

overlapping the time domain resource occupied by the first repetition of the common PUCCH repeated transmission with the time domain resource occupied by the target uplink channel transmission;

the transmission priority of the target uplink channel is lower than that of the common PUCCH repeated transmission;

the transmission priority of the target uplink channel is the same as the transmission priority of the common PUCCH, and the starting time of the repeated transmission of the common PUCCH is earlier than the starting time of the transmission of the target uplink channel.

Specifically, the first repetition may be preferentially guaranteed;

if the time domain resources occupied by the first time of repeated transmission of the public PUCCH and the time domain resources occupied by the target uplink channel transmission of the time domain resources occupied by the second time of repeated transmission still have overlapping, the target uplink channel transmission can be preferentially carried out on the time domain resources of the second time or later, or the common PUCCH repeated transmission can still be preferentially carried out.

Optionally, the transmission priority is agreed upon by the network side device configuration or protocol.

For example, the priority order of the collision channels may be defined, may be configured by the network side device, or may be predetermined by the protocol, and it is determined which channel is to be discarded according to the priority, that is, discarded with low priority;

for example, the transmission priorities are in order from high to low: first common PUCCH repetition > common PUCCH repetition other times than the first transmission > message msg a PUSCH > PRACH > PUSCH.

The network side device configuration may be, for example, that the network side device transmits configuration information to the terminal, including, for example, a transmission priority size, an order, and the like of the channels.

If the priority is the same, the priority transmission timing may be earlier, i.e., the priority transmission start time is earlier.

It should be noted that, in the embodiment of the present application, if a certain time slot has a conflict, the conflict is resolved based on the scheme of the above embodiment, that is, the conflict is discarded or transmitted, and other time slots may also continue to be transmitted, or the conflict is resolved based on the above embodiment.

Or, in the case of a paired pilot, collide with the target downlink channel to preferentially transmit the target downlink information, and discard common PUCCH repetition

Or, in half-duplex mode (half-duplex mode), discarding the common PUCCH repetition if the PUCCH repetition symbol does not satisfy the second condition.

Optionally, the target uplink channel includes at least one of PUSCH, PRACH, PUSCH carrying message a;

optionally, the target downlink channel includes at least one of SSB, PDCCH, PDSCH.

Optionally, the second condition comprises at least one of:

the first symbol of the common PUCCH repeated transmission is earlier than the first moment; the first time is the time when the last symbol of Downlink Control Information (DCI) for scheduling the PUSCH is backward for a first time length;

the last symbol of the common PUCCH repeated transmission is earlier than the time of the first symbol of the next SSB for a second time period;

the first symbol of the common PUCCH repeated transmission is later than the time when the last symbol of the last SSB is advanced for a third time length;

the first duration is PUSCH preparation time of the terminal;

the second time length is the minimum switching time from the sending to the receiving of the terminal in the half duplex mode

The third duration is the minimum switching time of the terminal from receiving and transmitting in the half duplex mode.

Specifically, the PUSCH preparation time of the terminal is determined by the capability of the terminal, i.e., the PUSCH preparation time of the terminal is the terminal

PUCCH repetition transmission can be generally used to solve the problem of PUCCH coverage on common PUCCH resources. The actual number of repetitions that can be performed may depend on the slot uplink and downlink configuration or the collision with other channels. In the above embodiment, it is given how to determine the first transmission slot occupied by the common PUCCH repeated transmission and how to solve the collision situation of other channels, so as to increase the number of repetitions that the common PUCCH can support to a greater extent, and further improve the reliability of receiving the common PUCCH.

step 201, receiving data of common PUCCH repeated transmission sent by a terminal; the common PUCCH repeated transmission is repeated transmission based on the first transmission slot occupied by the PUCCH repeated transmission.

Optionally, the first transmission time slot is determined based on a count type adopted by the terminal for common PUCCH repeated transmission.

Optionally, the count type is a default physical time slot based count of the number of repetitions; or alternatively, the first and second heat exchangers may be,

the counting type is a default counting of the repetition times based on the available time slots; or alternatively, the first and second heat exchangers may be,

The method further comprises the steps of:

sending first indication information to the terminal; the first indication information is used for indicating a counting type adopted by the terminal for carrying out common PUCCH repeated transmission; the count type includes counting the number of repetitions based on physical time slots or based on available time slots.

Optionally, if the count type is based on available time slots and the terminal uses a frequency band supporting unpaired spectrum, the first transmission time slot is N available time slots starting from a time slot where a time domain resource starting position of the common PUCCH retransmission is located, N is a positive integer, and at least one of the following is satisfied:

the target symbol is an uplink symbol;

the target symbol is a flexible symbol and is not overlapped with the symbol occupied by the synchronous signal block SSB;
