Description

Information indication method, terminal equipment, network equipment and system

Technical Field

The present application relates to the field of communications, and in particular, to an information indicating method, a terminal device, a network device, and a system

Background

In the New Radio (NR) technology of the fifth Generation (5th Generation, 5G) communication system, an uplink and downlink decoupling technology may be applied, that is, the network device and the terminal device may use, in addition to the TDD carrier with frequency F1 for uplink and downlink communication, an additional uplink carrier with frequency F2 for uplink communication, where the additional uplink carrier is usually called an uplink supplemental carrier (SUL), that is, the network device and the terminal device of NR may simultaneously have two uplink carriers for uplink communication, and the two uplink carriers correspond to one downlink carrier,

in the prior art, for a terminal device configured with two Uplink carriers, it is assumed that when the terminal device is scheduled by a network device to transmit a Physical Uplink Shared Channel (PUSCH) on a first Uplink carrier in a first time period, and the terminal device needs to transmit a Physical Uplink Control Channel (PUCCH) on a second Uplink carrier in a second time period, if the first time period and the second time period overlap, the terminal device may carry Uplink Control Information (UCI) that needs to be originally transmitted on the PUCCH of the second Uplink carrier on the PUSCH of the first Uplink carrier.

In the prior art, a rule for carrying UCI in a PUSCH is predefined, for example, the rule may be that UCI is carried in a first slot of a plurality of PUSCH slots; it is also possible that UCI is carried to all slots of a plurality of PUSCH slots and the same UCI is carried in each PUSCH slot, and so on.

Since feedback information such as Acknowledgement (ACK)/Negative Acknowledgement (NACK) in the UCI may correspond to different services, and delay and reliability requirements of the different services for ACK/NACK are different, if a predefined rule is not flexible enough, different requirements for UCI transmission time in the network cannot be met.

First, the related art and related terms referred to in this application are briefly introduced to facilitate the reader's understanding:

1) time domain resources

In a Long Term Evolution (LTE) system, channels are transmitted in units of Radio frames (Radio frames). One radio frame includes 10 subframes (subframes), each having a length of 1 millisecond (ms), and each including two slots (slots), each slot being 0.5 ms. The number of symbols included in each slot is related to the length of the Cyclic Prefix (CP) in the subframe. If the CP is a normal (normal) CP, each slot comprises 7 symbols and each subframe consists of 14 symbols, e.g., each subframe may consist of symbols with sequence numbers #0, #1, #2, #3, #4, #5, #6, #7, #8, #9, #10, #11, #12, #13, respectively. If the CP is a long (extended) CP, each slot includes 6 symbols and each subframe consists of 12 symbols, for example, each subframe may consist of symbols with sequence numbers #0, #1, #2, #3, #4, #5, #6, #7, #8, #9, #10, # 11. The "symbol" herein refers to an OFDM symbol.

In a New air interface (New RAT, NR) system, one radio frame is 10ms, and for a subcarrier spacing of 15kHz, one radio frame includes 10 slots, each of which is 1 ms. For a sub-carrier spacing of 30kHz, a radio frame consists of 20 slots, each of which is 0.5 ms. For a subcarrier spacing of 60kHz, one radio frame includes 40 slots, each of which is 0.25 ms. For a subcarrier spacing of 120kHz, one radio frame includes 80 slots, each of which is 0.125 ms. One slot includes 14 symbols.

2) Time slots of two uplink carriers

As shown in fig. 4, it is assumed that the frequency of the first NR TDD carrier is in a frequency band of 3.5GHz, the frequency of the second SUL carrier is in a frequency band of 1.8GHz, the timeslot labeled D is a downlink timeslot, the timeslot labeled U is an uplink timeslot, the subcarrier spacing on the NR TDD carrier is greater than the subcarrier spacing on the SUL carrier, and the length of the first timeslot on the NR TDD carrier is less than the length of the second timeslot on the SUL carrier. Typically, the subcarrier spacing on the NR TDD carrier is 30KHz and the subcarrier spacing on the SUL carrier is 15KHz, so that the time length of the first slot is half the time length of the second slot. It should be noted that the SUL carrier may be an uplink carrier used by the NR system independently, or may be an uplink carrier shared by the NR system and the LTE system.

3) Search space

In order to reduce the complexity of the terminal, two search spaces are defined in the LTE system, including a common search space and a terminal-specific search space. In the common search space, the aggregation level of the PDCCH may be 4, 8. In the terminal-specific search space, the PDCCH aggregation level may be 1, 2, 4, 8. In LTE, it is specified that a PDCCH can only be composed of n consecutive Control Channel Elements (CCEs), and only the ith CCE is used as a starting position, where i mod n is 0.

In the NR system, a Control Resource Set (CORESET) is defined, and the definition regarding the search space is similar to that of the LTE system, but the specific design of the search space and the PDCCH is different from that of the LTE system.

4) How to determine UCI transmission slots in the prior art

The uplink Signal sent by the terminal device to the network device generally includes a data Signal, a control Signal, and a measurement Signal, where the data Signal is carried on a PUSCH, the UCI is carried on a PUCCH, and the measurement Signal includes a Sounding Reference Signal (SRS). Specifically, the UCI includes ACK/NACK feedback Information, Channel State Information (CSI), and the like. In the same time period, the terminal device usually transmits uplink signals (including PUSCH/PUCCH/SRS) to the network device on only one uplink carrier (NR TDD carrier or SUL carrier).

The network device can configure the terminal device through a high-level signaling to indicate whether the terminal device PUSCH can be dynamically scheduled on any one of two uplink carriers, and the network device can realize the dynamic scheduling of the PUSCH carrier by adding an indication domain of one uplink carrier in downlink control information, and simultaneously, the network device can also configure one PUCCH carrier to the terminal device through the high-level signaling, so that the terminal device can only send the PUCCH on the uplink carrier configured as the PUCCH. Meanwhile, when the network device wants to send a Physical Downlink Shared Channel (PDSCH) to the terminal device, the network device first sends a Physical Downlink Control Channel (PDCCH) to the terminal device for scheduling, and the PDCCH carries Downlink Control Information (DCI) of a Downlink scheduling (DL grant). After receiving the PDSCH scheduled by the DL grant, the terminal device needs to send ACK/NACK feedback information to the network device to feed back whether the PDSCH is correctly received. The DL grant DCI carries a first field, where the first field indicates in which slot of the PUCCH the terminal device should send ACK/NACK feedback information to the network device, for example, the network device sends the PDCCH in slot n, and the first field in the DL grant DCI in the PDCCH indicates k, so that the terminal device sends ACK/NACK feedback to the network device in slot n + k.

According to the information indication method, the terminal device, the network device and the system provided by the embodiment of the application, the network device carries first indication information in downlink control information, the downlink control information is used for scheduling a downlink data channel, the terminal device feeds back uplink control information aiming at the downlink data channel, and the first indication information is used for indicating the terminal device to bear the uplink control information on time resources of a target uplink data channel. And realizing the dynamic configuration of the sending time of the uplink control information on the uplink data channel. The first indication information may multiplex a field used in downlink scheduling (e.g., DL grant DCI) in the downlink control information.

It should be noted that the embodiment of the present application may be applied to a case where the uplink data channel and the uplink control channel are time-overlapped when two uplink carriers transmit the uplink data channel and the uplink control channel, respectively, and may also be applied to a case where the uplink data channel and the uplink control channel are not time-overlapped.

Optionally, the uplink data channel may be a PUSCH or other channels for carrying uplink data information. The uplink control channel may be a PUCCH, or may be another channel for carrying uplink control information. The subcarrier spacing of the uplink data channel and the subcarrier spacing of the uplink control channel may be the same or different.

In addition, in this embodiment of the present application, the network device may also implicitly or explicitly carry second indication information in a downlink Control channel (or Radio Resource Control (RRC), Medium Access Control (MAC) layer signaling), where the second indication information is used to indicate that the function of the first indication information is to indicate the terminal device to send the uplink Control information on an uplink data channel or an uplink Control channel.

Specifically, an embodiment of the present application provides an information indication method, and as shown in fig. 5, the method includes:

s101, the network equipment sends first indication information to the terminal equipment.

The first indication information is indication information indicating a first time resource, and is specifically used for indicating the terminal device to send uplink control information to the network device on a first channel of the first time resource. The first channel described herein is a channel for carrying uplink data information, such as a PUSCH.

In a possible implementation manner, the first indication information may be carried by downlink control information. Specifically, the network device may send downlink control information to the terminal device, where the downlink control information includes the first indication information. The downlink control information may be used for downlink scheduling, for example, the role played by the first field in the DL grant DCI described above.

That is, the downlink control information is originally used to instruct the terminal device to receive downlink data information from the network device on a third channel of a third time resource, where the third channel is a channel for carrying the downlink data information, such as the PDSCH. Correspondingly, the uplink control information that the terminal device originally wants to feed back to the network device carries response feedback information (for example, ACK/NACK) corresponding to the downlink data information. The method and the device carry first indication information in the downlink control information, and are used for indicating the terminal device to send uplink control information including response feedback information corresponding to the downlink data information to the network device on an uplink data channel of the first time resource.

It is to be simply understood that the first indication information has a similar function to that of the first field in the DL grant DCI described above, and explicitly indicates a time resource, except that it implicitly indicates a time resource corresponding to an uplink data channel instead of a time resource corresponding to an uplink control channel.

The first indication information may implicitly multiplex the first field in the DL grant DCI as described above, and other indication information is needed to cooperate with the first field, and the discussion will be further developed. Or, the first indication information may be explicitly carried by a newly added field in the downlink control information, where the field is only used to indicate the first time resource, and the first field in the downlink control information DL grant DCI is still used to indicate the terminal device to send the response feedback information corresponding to the downlink data information to the network device.

S102, the terminal equipment receives first indication information from the network equipment.

In a possible implementation manner, the terminal device may receive downlink control information from the network device, where the downlink control information includes the first indication information, and as described above, the downlink control information may be used for downlink scheduling.

S103, the terminal equipment sends uplink control information to the network equipment on a first channel of the first time resource according to the first indication information.

Optionally, the first time resource may be one or more continuous or discontinuous or partially continuous time slots, one or more continuous or discontinuous or partially continuous symbols, or a subframe, a micro-slot, or the like.

Optionally, the first time resource may be one of a plurality of candidate time resources; or, the first time resource may be multiple time resources in multiple candidate time resources, the terminal device may send uplink control information to the network device on a first channel of each time resource in the first time resource, the terminal device may repeatedly send the same uplink control information on each time resource, which is convenient for the network device to correctly analyze, the terminal device may also split the uplink control information into multiple portions, send one of the portions on each time resource, and finally the network device merges the portions into complete uplink control information. The candidate time resources may be a plurality of time resources that are continuous in time, or may be a plurality of time resources that are discontinuous in time or partially continuous in time. For example, the plurality of candidate time resources are 4 consecutive time slots, each candidate time resource is one of the 4 consecutive time slots, and the first indication information indicates one of the 4 time slots of the first time resource. Of course, the plurality of candidate resources may be 6 or 8 consecutive time slots, and the number of the plurality of candidate time resources is not limited in this embodiment. The candidate time resources may be determined by the terminal device according to a rule predefined in the protocol, or may be pre-configured by the network device to the terminal device. For example, the candidate time resources may be uplink time slots closest to a first downlink time slot, where the first downlink time slot is a time slot in which the terminal device receives the first indication information, and the uplink time slots are time slots subsequent to the first downlink time slot in time.

As described above, the first channel is a channel for carrying uplink data information. That is, the first channel is originally used for carrying uplink data information, for example, the first channel may be a PUSCH, and is used for carrying uplink control information in the present application.

S104, the network equipment receives uplink control information from the terminal equipment on a first channel of the first time resource.

According to the information indication method provided by the embodiment of the application, the network equipment indicates the time resource, and the terminal equipment sends the uplink control information to the network equipment on the uplink data channel of the time resource, so that the network equipment can control the time when the uplink control information is fed back on the uplink data channel, and the time when the uplink data information is sent on the uplink data channel is dynamically configured.

In the following, the first indication information is implicitly multiplexed, and optionally, referring to fig. 6, before step S103, the method may further include:

s201, the network equipment sends second indication information to the terminal equipment.

The second indication information of the present application may include two states, and if the second indication information is the first state, the second indication information is used to indicate that the first field in the downlink control information carries the first indication information. If the second indication information is in the second state, the second indication information is used to indicate that the first field carries third indication information, where the third indication information is used to indicate that the terminal device sends response feedback information to the network device on a second channel of the second time resource, and the second channel is a channel used to carry uplink control information, for example, the second channel may be a PUCCH.

It is to be understood that, since the first indication information is used for multiplexing the downlink control information, that is, the first indication information uses a first field in the downlink control information, which indicates the terminal device to send the response feedback information to the network device, the second indication information is needed to explain in order to distinguish which of the two functions is specifically indicated by the first field. The first field may be a field for indicating ACK/NACK feedback time resources in a DL grant, which has a length of 3 bits.

The second indication information may be carried in various ways as long as two different states can be distinguished, and the present application is not limited thereto. Optionally, the second indication information may be carried in a mask of Cyclic Redundancy Check (CRC) of the downlink control information, and if the mask is a first mask, the first field carries the first indication information, and if the mask is a second mask, the first field carries the third indication information. Specifically, in the case where the CRC has a length of 24 bits, the first mask and the second mask may be as shown in table 1 below. In case that the length of the CRC is 16 bits, the first mask and the second mask may be as shown in table 2 below. The length of the CRC may also be other values, such as 32 bits, etc., which are not limited herein. In table 1 and table 2, the first mask is all 0 s, and the second mask is all 1 s, but it is understood that the first mask may be all 1 s, and the second mask may be all 0 s. Of course, the first mask and the second mask may also be other masks that are not all 1's, and are not limited herein.

		First mask	<0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0>
Second mask	<1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1>

	CRC mask
		First mask	<0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0>

Or, the second indication information may be carried in a search space of the downlink control information, and if the downlink control information is located in the first search space, the first field carries the first indication information; and if the downlink control information is located in the second search space, the first field carries third indication information.

Optionally, the first channel and the second channel may be located in different or the same uplink carrier, that is, the uplink data channel may be located in the first uplink carrier, the uplink control channel may be located in the second uplink carrier, and the first uplink carrier and the second uplink carrier may be the same or different. If the first uplink carrier is different from the second uplink carrier, the first uplink carrier may be an NR TDD carrier and the second uplink carrier may be an SUL carrier, or the first uplink carrier may be an SUL carrier and the second uplink carrier may be an NR TDD carrier. In addition, the first uplink carrier may also be an uplink carrier of a first cell, and the second uplink carrier may be an uplink carrier of a second cell, for example, the first cell may be a primary cell, and the second cell may be a secondary cell, or the first cell may be a secondary cell, and the second cell may be a primary cell.

Optionally, in a case that the first channel and the second channel are located on different uplink carriers, the second indication information may be a 1-bit field in the downlink control information. For example, when the 1-bit field takes a value of 0, the second indication information is used to indicate that the first field in the downlink control information carries the first indication information, and when the 1-bit field takes a value of 1, the second indication information is used to indicate that the first field in the downlink control information carries the third indication information, or vice versa. For example, the second indication information may multiplex a second field used for indicating an uplink carrier identifier in the downlink control information, where the length of the second field may be 1 bit, the terminal device determines the uplink carrier corresponding to the uplink carrier identifier according to the second field, and because the uplink carrier corresponds to the first channel or the second channel, the terminal device determines the first channel or the second channel according to the uplink carrier, thereby determining that the first field carries the first indication information or the third indication information.

Alternatively, the second time resource may be one or more consecutive slots, one or more consecutive symbols.

It should be noted that, when the first indication information is explicitly carried by the added field, if the second indication information indicates that the terminal device carries the uplink control information on the uplink control channel, the added field may not be included in the downlink control information, or the added field is an all-0-bit field.

It should be noted that, when the second indication information is in the first state, the first field of the implicit multiplexing carries the first indication information; if the second indication information is in the second state, the first field may be used for other purposes in other scenarios, for example, carrying feedback response feedback information of the indication terminal device.

Optionally, when the first indication information is explicitly carried by a newly added field, the bit number of the newly added field may be determined according to a relationship between subcarrier intervals of the first uplink carrier and the second uplink carrier. Specifically, when the subcarrier spacing of the first uplink carrier is 2 times the subcarrier spacing of the second uplink carrier, such as {30kHz,15kHz } or {60kHz,30kHz } or {120kHz,60kHz } or the like, the newly added field may be a 1-bit field. When the subcarrier spacing of the first uplink carrier is 4 times the subcarrier spacing of the second uplink carrier, such as {60kHz,15kHz } or {120kHz,30kHz }, the newly added field may be a 2-bit field. When the subcarrier spacing of the first uplink carrier is 8 times the subcarrier spacing of the second uplink carrier, such as {120kHz,15kHz } or the like, the newly added field may be a 3-bit field. In addition, when the subcarrier spacing of the first uplink carrier is equal to the subcarrier spacing of the second uplink carrier, the newly added field may be 0 bit, i.e., the newly added field is not carried.

Optionally, when the first indication information is explicitly carried by a newly added field, the newly added field indicates a relative position of the first time resource and the second time resource, for example, the second time resource is a timeslot # n2, the timeslot # n2 has a time overlap with the timeslot # n1 on the first uplink carrier, and the newly added field may indicate k, where k is an integer, thereby indirectly indicating that the first time resource is a timeslot # (n1+ k) on the first uplink carrier. Specifically, the new field may be a 1-bit field, where the state "0" corresponds to k being 0, and the state "1" corresponds to k being-1, so that when the new field is 0, the first time resource is indicated as the timeslot # n1 on the first uplink carrier, and when the new field is 1, the first time resource is indicated as the timeslot # on the first uplink carrier (n 1-1). For another example, if the state "0" corresponds to k being 0 and the state "1" corresponds to k being 1, the new field is 0, indicating that the first time resource is the timeslot # n1 on the first uplink carrier, and if the new field is 1, indicating that the first time resource is the timeslot # (n1+1) on the first uplink carrier.

Alternatively, when the first indication information is carried by multiplexing the existing field, it has been described above that the existing field may be a 3-bit field. When the subcarrier spacing of the first uplink carrier is 2 times the subcarrier spacing of the second uplink carrier, the first indication information may be carried in 1 bit in the existing field, where the 1 bit may be the lowest order bit or the highest order bit of the 3-bit existing field, which is not limited herein. When the subcarrier spacing of the first uplink carrier is 4 times the subcarrier spacing of the second uplink carrier, the first indication information may be carried in 2 bits in the existing field, where the 2 bits may be the lower 2 bits or the upper 2 bits of the existing 3-bit field, which is not limited herein. When the subcarrier spacing of the first uplink carrier is 8 times of the subcarrier spacing of the second uplink carrier, the existing 3-bit field is all used for carrying the first indication information.
