Description

Uplink information transmission method and device

Technical Field

The invention relates to the technical field of communication, in particular to the technical field of uplink information transmission.

Background

Unlicensed spectrum is a nationally and regionally divided spectrum that can be used for radio communications and is generally considered to be a shared spectrum, i.e., communication devices in different communication systems can use the spectrum as long as the regulatory requirements set by the country or region on the spectrum are met, without requiring a proprietary spectrum license to be applied to the government. With the development of wireless communication technology, both LTE (Long Term Evolution ) and NR (New Radio) systems consider to be networked on unlicensed spectrum, so as to use unlicensed spectrum for data traffic transmission.

In order for individual communication systems using unlicensed spectrum to be able to co-exist friendly over that spectrum, some countries or regions have stipulated regulatory requirements that must be met using unlicensed spectrum. For example, the communication device follows the principle of Listen Before Talk (LBT), that is, the communication device needs to perform channel interception before performing signal transmission on a channel of the unlicensed spectrum, and only when the channel interception result is that the channel is idle, the communication device can perform signal transmission; if the channel listening result of the communication device on the channel of the unlicensed spectrum is that the channel is busy, the communication device is unable to signal.

In the above process, if the UE fails to perform HARQ-ACK feedback because of LBT failure, the UE can only wait for the next scheduling of the network device to perform HARQ-ACK feedback, which has a larger waiting delay. Similarly, if periodic or aperiodic CSI is reported, the UE cannot report because of LBT failure, and can only wait for the next reporting opportunity, and the delay of reporting waiting is larger.

The following embodiments of the present application will describe in detail how a user equipment reports UCI information to a network device using CG-PUSCH.

Embodiment one

Referring to fig. 2, an uplink information transmission method according to a first embodiment of the present application includes:

step S210, user equipment maps target uplink control information to a Physical Uplink Shared Channel (PUSCH), wherein the PUSCH is used for authorizing uplink resource transmission through pre-configuration, the target uplink control information comprises first uplink control information, and first indication information in the first uplink control information is used for determining whether the PUSCH comprises second uplink control information or not;

step S220, the ue sends the PUSCH to the network device through the preconfigured grant uplink resource.

Optionally, the first uplink control information and the second uplink control information are different. Optionally, the first uplink control information includes control information for demodulating the PUSCH, and the second uplink control information includes uplink control information for downlink transmission, for example: feedback information of a downlink channel, channel quality information of the downlink channel, and the like. Optionally, the difference means that the first uplink control information and the second uplink control information are independently channel coded. Specifically, the first uplink control information may be CG-UCI for demodulating the PUSCH. However, the first uplink control information is not limited to demodulation of the PUSCH, and may be used to demodulate other control information. For example, if uplink data is included in the PUSCH, the CG-UCI includes control information for demodulating the uplink data; and/or, if other UCI than CG-UCI is included in the PUSCH, the CG-UCI includes control information for demodulating the other UCI.

Specifically, the second uplink control information is other UCI than CG-UCI. The CG-UCI is used to indicate whether other UCI than CG-UCI is included in the PUSCH, that is, the user equipment notifies the network equipment through the CG-UCI, and whether it has sent other UCI than CG-UCI to the network equipment.

Optionally, the second uplink control information is other uplink control information different from the first uplink control information, for example: when the first uplink control information is CG-UCI, the second uplink control information is UCI other than CG-UCI. Also for example: the first indication information includes 1 bit, where the 1 bit is used to indicate that the pre-configured grant uplink resource CG-PUSCH does not carry other types of UCI except CG-UCI, or the 1 bit is used to indicate that the CG-PUSCH carries other types of UCI except CG-UCI.

Optionally, the second uplink control information includes at least one of hybrid automatic repeat request response HARQ information and channel state information CSI. Optionally, the CSI includes at least one of first partial channel state information CSIPart 1 and second partial channel state information CSIPart 2.

Alternatively, the ue may decide at its discretion that feedback information is required to the network device. The first indication information is specifically configured to indicate whether the PUSCH includes the second uplink control information that the UE determines to transmit. As an example, the first indication information may indicate one of the following states: the HARQ information is included in the PUSCH, and the HARQ information is not included in the PUSCH.

It should be understood that, when the user equipment determines to transmit PUSCH through the pre-configured grant uplink resource, if the pre-configured grant uplink resource at least partially overlaps with an uplink resource of the user equipment for transmitting a physical uplink control channel PUCCH in a time domain, the user equipment may carry part or all of uplink control information (for example, HARQ information, CSIPart 1, CSIPart2, etc.) to be transmitted in the PUCCH to transmit on the PUSCH. Since the HARQ information reflects the downlink scheduling situation (e.g., decoding corresponding to PDSCH) of the network device, HARQ information feedback is only needed if downlink scheduling occurs. In addition, on the unlicensed spectrum, the network device may also use the trigger information to trigger the ue to perform HARQ information feedback, for example, trigger the ue to perform HARQ feedback based on the PDSCH channel group or feedback based on the full codebook. When the network device sends a PDCCH for scheduling PDSCH to the user device or when the network device sends a trigger signaling to the user device to trigger the user device to perform HARQ feedback, if the user device does not correctly receive the PDCCH or does not correctly receive the trigger signaling, the user device will not feedback HARQ information, but at this time, the network device will expect the user device to feedback HARQ information. The understanding of whether the user equipment and the network equipment need to transmit the HARQ information is inconsistent, so that the understanding of rate matching is inconsistent, and the demodulation performance of the network equipment is further affected. Therefore, optionally, the first indication information is used to indicate whether HARQ information is included in the PUSCH. The first indication information may indicate one of the following states: the HARQ information is included in the PUSCH, and the HARQ information is not included in the PUSCH. In this embodiment, the ue indicates, in first indication information in the first control information, whether HARQ-ACK information is transmitted or not, so that the network device may perform correct rate matching according to the first indication information.

Alternatively, the first embodiment of the present application may include at least one of the following cases:

case one

The target uplink control information comprises the HARQ information, and the first indication information indicates that the HARQ information is included in the PUSCH. Optionally, the first indication information is used to indicate one of the following states: the HARQ information is included in the PUSCH, and the HARQ information is not included in the PUSCH.

Optionally, the first uplink control information further includes second indication information, where the second indication information is used to indicate at least one of the following information: the feedback type of the HARQ information comprises at least one of dynamic codebook feedback, one-shot codebook feedback and semi-static codebook feedback; the number of information bits of the HARQ information; the number of resources occupied by the HARQ information; a channel group identifier corresponding to the HARQ information; the total number of downlink allocation indications T-DAI corresponding to the channel group; new feedback group indication information NFI corresponding to the channel group; carrier identification corresponding to the HARQ information; a process number or a process number group corresponding to the HARQ information; the new data corresponding to the process number indicates NDI; and the HARQ feedback window corresponds to the HARQ information.

Optionally, the feedback type of the HARQ information is dynamic codebook feedback, and the codebook corresponding to the HARQ information is determined according to at least one of the following: the channel group identification to be fed back, the downlink allocation indication count C-DAI corresponding to the channel group, the T-DAI corresponding to the channel group, the NFI corresponding to the channel group and the carrier identification corresponding to the HARQ information.

Optionally, the codebook corresponding to the HARQ information is arranged according to the order of the C-DAIs in the channel group to be fed back.

For example, referring to fig. 3, in the first transmission opportunity, the ue receives the PDSCH transmitted by the network device, expects the ue to feedback the three HARQ information corresponding to the channel group 0 on the PUCCH 0, but fails to feedback the three HARQ information corresponding to the channel group 0 on the PUCCH 0 due to LBT failure. In the second transmission opportunity, the ue receives PDSCH sent by the network device, and expects that the ue feeds back three HARQ information corresponding to channel group 0 and two HARQ information corresponding to channel group 1 on PUCCH 1, however, the ue fails to feed back HARQ information corresponding to channel group 0 and channel group 1 on PUCCH 1 due to LBT failure. After PUCCH 1, there is a CG-PUSCH resource, if the user equipment obtains the channel usage right of the CG-PUSCH resource, the user equipment can feed back the HARQ information corresponding to the channel group 0 and the channel group 1 to the network equipment through the CG-PUSCH resource. The first indication information includes feedback group 0, total number of DAIs in feedback group 0 is 3, NFI value of feedback group 0 is 1, feedback group 1, total number of DAIs in feedback group 1 is 2, NFI value of feedback group 1 is 0. Accordingly, the codebook based on C-DAI ordering fed back by the user equipment on the CG-PUSCH is shown in Table 1 below. The codebook order shown in table 1 is sequentially arranged in the order of the first one at the left and the last one at the last:

TABLE 1

Optionally, the feedback type of the HARQ information is dynamic codebook feedback, the channel group to be fed back includes all channel groups corresponding to PDSCH received by the ue, and the codebook corresponding to the HARQ information is determined according to at least one of the following: the process number or the process number group corresponding to the HARQ information, the NFI corresponding to the channel group and the carrier identification corresponding to the HARQ information.

Optionally, the codebook corresponding to the HARQ information is arranged according to the sequence of all HARQ process numbers.

For example, with continued reference to fig. 3, as such, the user equipment fails to feedback HARQ information on PUCCH 0 in both the first transmission opportunity and the second transmission opportunity. After obtaining the channel usage right of one CG-PUSCH resource, HARQ information is sent to the network equipment through the CG-PUSCH resource. The first indication information includes feedback indication information of all groups, indication information of NFI value 1 of group 0 and indication information of NFI value 0 of group 1. Accordingly, the codebook based on the HARQ process number sequence fed back by the user equipment on the CG-PUSCH is shown in table 2 below. The codebook order shown in table 2 is first front and last from the left of each line; then, the uppermost first row is at the forefront, and the last row is sequentially arranged in the last order:

TABLE 2

Optionally, the feedback type of the HARQ information is one-shot codebook feedback, and the codebook corresponding to the HARQ information is determined according to at least one of the following: the carrier wave identification corresponding to the HARQ information, the process number or the process number group corresponding to the HARQ information and the NDI corresponding to the process number.

Optionally, the codebook corresponding to the HARQ information is arranged according to the sequence of all HARQ process numbers. Optionally, the second uplink control information includes, in addition to HARQ information corresponding to all HARQ process numbers, NDI corresponding to all HARQ process numbers.

For example, with continued reference to fig. 3, again, when the user equipment fails to feedback HARQ information on PUCCH 0 in both the first transmission opportunity and the second transmission opportunity. And then after obtaining the channel usage right of one CG-PUSCH resource, HARQ information is sent to the network equipment through the CG-PUSCH resource. The third indication information comprises indication information fed back by the full codebook HARQ-ACK and indication information of corresponding carrier identification information. Accordingly, the codebook based on the HARQ process number order fed back by the user equipment on the CG-PUSCH is shown in table 3 or 4 below. In table 3, NDI information of all HARQ processes is fed back first, and HARQ information of all HARQ processes is fed back. In table 4, NDI information and HARQ information for each HARQ process are fed back in cascade. The codebook orders shown in tables 3 and 4 are first front and last from the left of each row; then, the uppermost first row is at the forefront, and the last row is sequentially arranged in the last order:

TABLE 3 Table 3

TABLE 4 Table 4

Optionally, the feedback type of the HARQ information is a semi-static codebook feedback, and the codebook corresponding to the HARQ information is determined according to at least one of the following: and the carrier wave identification corresponding to the HARQ information and the HARQ feedback window corresponding to the HARQ information.

Optionally, the codebook corresponding to the HARQ information is sequentially arranged according to the HARQ feedback window. The network device configures a K1set (K1 set) and a time domain resource allocation table for the terminal device through protocol predefining or high-layer signaling, the terminal device determines candidate time domain positions of the PDSCH according to the time domain resource allocation table, and determines time slots where feedback information of the PDSCH is possible according to the candidate time domain positions of the PDSCH and the K1 set. The time slot in which feedback information of the PDSCH may be located is referred to as a HARQ feedback window. In each uplink time slot, the terminal equipment determines a PDSCH time set associated with the uplink time slot according to the candidate time domain position and the K1set of the PDSCH, namely an associated downlink time slot and a PDSCH time set in the downlink time slot, and then generates a feedback codebook according to the associated PDSCH time set.

Case two

Optionally, the first indication information indicates that the PUSCH includes the CSIPart 1, and the target uplink control information includes the CSIPart 1; and/or, the first indication information indicates that the PUSCH includes the CSIPart 2, and the target uplink control information includes the CSIPart 2.

Optionally, the first indication information is specifically configured to indicate one of the following states: the PUSCH includes the CSI, the PUSCH includes no CSI, the PUSCH includes first partial channel state information CSIPart1, the PUSCH includes no CSI Part1, the PUSCH includes second partial channel state information CSIPart 2, and the PUSCH includes no CSIPart 2. Optionally, the state including the CSI includes one of: the PUSCH includes first partial channel state information CSIPart1, and the PUSCH includes second partial channel state information CSIPart 2. The state excluding the CSI includes one of: the PUSCH does not include the CSIPart1, and the PUSCH does not include the CSIPart 2.

Optionally, the first uplink control information further includes third indication information; when the first indication information indicates that at least one of the CSIPart1 and the CSIPart 2 is included in the PUSCH, the third indication information is used for indicating at least one of the following information: determining information of the information bit number of the CSIPart 1; determining information of the information bit number of the CSIPart 2; determining information of the number of resources occupied by the CSIPart 1; and determining information of the number of resources occupied by the CSIPart 2.

Optionally, in view of any one of the foregoing alternatives in the first embodiment of the present application, the first uplink control information in the first embodiment of the present application may further include fourth indication information, where the fourth indication information is used to make a scheduling request SR.

Optionally, the fourth indication information further includes priority and/or data volume information of the data to be scheduled.

The UCI type for transmission on the preconfigured grant uplink resource (e.g., CG-PUSCH) may include at least one of: CG-UCI, HARQ-ACK, CSIPart 1 and CSIPart 2. In order to ensure the reliability of UCI transmitted on CG-PUSCH, a code rate compensation factor may be defined for UCI information, i.e. more REs (resource elements) may be allocated to UCI of the same bit, which improves the transmission reliability of the first UCI by reducing the UCI code rate.

Optionally, in order to ensure the reliability of transmitting the UCI on CG-PUSCH, a code rate compensation factor may be defined for the UCI information, i.e. more RE resources may be allocated to the UCI of the same bit, which improves the transmission reliability of the UCI by reducing the UCI code rate.

Optionally, if the downlink control signaling DCI activating CG-PUSCH includes a code rate compensation factor indicator field, the code rate compensation factor may be semi-statically configured to a set for a user equipment through higher layer signaling, and then dynamically indicated to the user equipment through the DCI.

Alternatively, if the DCI signaling for activating CG-PUSCH does not include a code rate compensation factor indicator field, or CG-PUSCH does not require DCI activation, the code rate compensation factor is the UCI of the higher layer configured parameter β.

For the case that the CG-PUSCH carries uplink data, a parameter (α) of a higher layer signaling configuration may also be introduced for transmission of the UCI information ^{First UCI} ) This parameter is used to limit the upper limit of the number of occupied REs of the UCI information.

For the case that the CG-PUSCH does not carry uplink data, the number of RE resources occupied by the UCI may be calculated by at least one of the total number of bits of the UCI information, the reference code rate, the modulation order, and the code rate compensation factor β. The reference code rate and the modulation order may be configured semi-statically by high-layer signaling, or may be indicated by DCI signaling for activating CG-PUSCH.

Optionally, if the UCI is not CG-UCI, the code rate compensation factor βfirst UCI and/or the resource limitation parameter αfirst UCI of the UCI may also be obtained by: taking the code rate compensation factor as an example, the network device configures a code rate compensation factor set for the terminal device through a high-layer signaling semi-static state, the terminal device selects the code rate compensation factor from the code rate compensation factor set and reports the selected code rate compensation factor to the network device, for example, the terminal device reports the selected code rate compensation factor to the network device through CG-UCI.

Alternatively, if the UCI is not CG-UCI, the terminal device may report the total number of bits of the UCI, the number of occupied resources, and/or the location (e.g., symbol location or RB/RE location) of the occupied resources to the network device. For example, the terminal device reports the total number of bits of the UCI (the total number of bits after encoding), the number of occupied resources and/or the location of the occupied resources to the network device through the CG-UCI.

In the first embodiment of the present application, a user equipment maps target uplink control information to a PUSCH, and then sends the PUSCH through a preconfigured authorized uplink resource, where the target uplink control information includes first uplink control information, and notifies the network equipment whether the PUSCH includes second uplink control information through first indication information in the first uplink control information, so as to enable the user equipment to actively report uplink control information for downlink transmission to the network equipment, for example: feedback information of a downlink channel or channel quality information of the downlink channel, and the like, without feeding back uplink control information based on scheduling of network equipment, reduces or shortens waiting time delay of UCI reporting of user equipment.
