Detailed Description
The embodiment of the invention provides an information configuration method, which can send at least one HARQ feedback information through part of time domain symbols in the same subframe, so that UE with double-chain receiving capability and single-chain transmitting capability can respectively send the HARQ feedback information to different network nodes at the same moment, in addition, the utilization rate of the time domain symbols is improved, and the sending speed of the HARQ feedback information is accelerated. The embodiment of the invention also provides corresponding equipment and a system. The following will describe in detail.
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to fall within the scope of the invention.
The terminal in the embodiment of the invention can be a mobile phone, a palm computer, a notebook computer, a personal computer and other terminal devices, the network node in the embodiment of the invention can be an Access Point (AP) or a base station, the base station can include a macro base station and a small base station, and uplink signals of the macro base station and the small base station can be carried on different uplink carriers or the same uplink carrier. Different uplink carriers are located in different frequency bands and have different center carrier frequencies. In a carrier aggregation (CA, carrier Aggregation) system, the uplink carrier may also be referred to as an uplink component carrier.
In order to make the embodiment of the present invention more clear, a simple description will be given of the frame structure and the channel carrying HARQ feedback information in the system.
The time domain is identified by Radio frames (Radio frames), each consisting of 10 subframes (subframes) of 1ms length, each consisting of 12 or 14 symbols (symbols), wherein the uplink time domain symbols are referred to as Single-carrier frequency division multiple access (SC-FDMA, single-Carrier Frequency Division Multiple Access) symbols and the downlink symbols are referred to as orthogonal frequency division multiplexing (OFDM, orthogonal Frequency Division Multiplexing) symbols. For a frequency division duplex (FDD, frequency Division Duplexing) system, each subframe includes 2 slots (slots). For a time division duplex (TDD, time Division Duplexing) system, subframe 1 is a special subframe (special subframe), and subframe 6 is set as a special subframe or a downlink subframe according to the TDD uplink and downlink configuration. The special subframe consists of a downlink pilot time slot (DwPTS, downlink Pilot TimeSlot), a Guard Period (GP), and an uplink pilot time slot (UpPTS, uplink Pilot TimeSlot).
When the downlink transmission supports the HARQ technology, after receiving data carried by the PDSCH (Physical Downlink Share Channel, physical downlink shared channel), the UE needs to send HARQ feedback information to the network node. When the PDSCH receives correctly, the UE feeds back ACK, and when the PDSCH receives incorrectly, the UE feeds back NACK. At the time of sending the HARQ feedback information, if no PUSCH needs to be sent, ACK/NACKIs transmitted on a physical uplink control channel (PUCCH, physical Uplink Control Channel). The PUCCH sequence is composed of a base sequenceThe relationship between the PUCCH sequence and the base sequence, which is generated by performing cyclic shift α, can be expressed by the formula: />0≤n＜M SC Wherein->For the expression of the PUCCH sequence, +.>Is an expression of the base sequence, e jαn For cyclic shift variable, M SC Is the PUCCH sequence length. The linear phase rotation in the frequency domain corresponds to the cyclic shift in the time domain.
Referring to fig. 1, an embodiment of a method for configuring information provided in an embodiment of the present invention includes:
101. the terminal receives a configuration signaling sent by a network node, wherein the configuration signaling is used for indicating that when the terminal sends at least one HARQ feedback information, each HARQ feedback information occupies part of time domain symbols in the same subframe.

The HARQ feedback information includes: correct Acknowledgement (ACK) or incorrect Acknowledgement (NACK).
The time domain symbols in the embodiments of the present invention include uplink time domain symbols or slots.
Taking 14 uplink time domain symbols as an example of one subframe, in the embodiment of the present invention, HARQ feedback information only needs to occupy part of uplink time domain symbols in the 14 uplink time domain symbols, and does not need to occupy all uplink time domain symbols, so that other uplink time domain symbols can be used to carry other HARQ feedback information or data carried by PUSCH. Preferably, the uplink time domain symbols occupied by the HARQ feedback information are not more than 7.
102. And the terminal configures the at least one HARQ feedback information on part of time domain symbols in the same subframe occupied by each HARQ feedback information.
In the embodiment of the invention, the terminal configures each HARQ feedback information on part of time domain symbols in the same subframe according to the indication in the configuration signaling.

103. And the terminal sends the configured at least one HARQ feedback information to the network node.
After the terminal configures the HARQ feedback information on the time domain symbols in the same subframe, the terminal sends the configured at least one HARQ feedback information to the network node.
The embodiment of the invention adopts a configuration signaling sent by a receiving network node, wherein the configuration signaling is used for indicating the terminal to send at least one HARQ feedback information when the HARQ feedback information is requested by the hybrid automatic repeat request, and each HARQ feedback information occupies part of time domain symbols in the same subframe; configuring the at least one HARQ feedback information on part of time domain symbols in the same subframe occupied by each HARQ feedback information; and sending the configured at least one HARQ feedback information to the network node. Compared with the prior art that the UE cannot send the HARQ feedback information to two network nodes at the same time, the technical scheme provided by the embodiment of the invention can send at least one HARQ feedback information through part of time domain symbols in the same subframe, so that the UE with double-chain receiving capability and single-chain transmitting capability can respectively send the HARQ feedback information to different network nodes at the same time, in addition, the utilization rate of the time domain symbols is improved, and the sending speed of the HARQ feedback information is accelerated.
Optionally, on the basis of the embodiment corresponding to fig. 1, in another embodiment of the method for configuring information provided by the embodiment of the present invention, the HARQ feedback information includes: correct acknowledgement ACK or incorrect acknowledgement NACK;
when one piece of HARQ feedback information is to be sent, the configuration signaling is used for indicating one pre-designated uplink time domain symbol or one pre-designated time slot of the network node in the same subframe occupied by the one piece of HARQ feedback information;
correspondingly, the configuring the at least one HARQ feedback information on a part of time domain symbols in the same subframe occupied by each HARQ feedback information includes:

And respectively configuring the two HARQ feedback information on different time slots pre-designated by the network node in the same subframe.
In the embodiment of the present invention, when an HARQ feedback message is to be sent, the HARQ feedback message may be configured on an uplink time domain symbol pre-designated by the network node in the same subframe, such as the last uplink time domain symbol, which is, of course, only an example, and other uplink time domain symbols are also possible. When there are two slots in the same subframe, the HARQ feedback information may be configured on a slot pre-designated by the network node, such as the first slot or the second slot.
When two pieces of HARQ feedback information are to be transmitted, the two pieces of HARQ feedback information are respectively configured on different time slots pre-designated by the network node, for example, a first piece of HARQ feedback information is configured on the first time slot, a second piece of HARQ feedback information is configured on the second time slot, and of course, the two pieces of HARQ feedback information can be configured in reverse, and the terminal is configured completely according to requirements in configuration signaling transmitted by the base station.
Optionally, in another embodiment of the information configuration provided in the foregoing alternative embodiment of fig. 1, when the HARQ feedback information occupies one uplink time domain symbol pre-specified by the network node in the same subframe, the HARQ feedback information is indicated by a cyclic shift value of a physical uplink control channel (PUCCH, physical Uplink Control Channel) sequence.
In the embodiment of the invention, different cyclic shift values indicate different ACK/NACK states. The cyclic shift value and the ACK/NACK state are in one-to-one correspondence. Specifically, the base station may inform the UE of a cyclic shift value for indicating an ACK/NACK state through higher layer signaling or physical layer signaling, or a standard predefines a cyclic shift value for indicating an ACK/NACK state. For example, the cyclic shift value α=0 represents ACK, α=m SC The/2 represents NACK, or the cyclic shift value α=0 represents NACK, α=m SC And/2 represents ACK.
PUCCH sequence length M SC The sequence length of the PUCCH may be predefined by the standard or may be signaled by the network node to the UE via higher layer signaling. Preferably, the sequence length M of PUCCH SC The frequency resource can be multiplexed with the existing PUCCH format in this way, because the PUCCH designed by the embodiment of the present invention can be made orthogonal to the sequence adopted by the existing PUCCH format.
Optionally, on the basis of the embodiment corresponding to fig. 1 and the two optional embodiments corresponding to fig. 1, before the step of sending the at least one HARQ feedback information to the network node, another embodiment of the method for configuring information provided by the embodiment of the present invention may further include:

In the embodiment of the present invention, if in the TDD system, the third reserved resource is located in the uplink pilot time slot UpPTS, and when the terminal sends the at least one HARQ feedback information, the third reserved resource is sent.
Optionally, in another optional embodiment of the method for configuring information provided by the embodiment of the present invention on the basis of the first optional embodiment corresponding to fig. 1, when sending an HARQ feedback information and simultaneously resending data carried by a physical uplink shared channel through the same subframe, the configuration signaling is configured to instruct that the data carried by the physical uplink shared channel occupy other uplink time domain symbols in the same subframe except for one uplink time domain symbol pre-designated by the network node occupied by the HARQ feedback information;
correspondingly, the configuring the at least one HARQ feedback information on a part of time domain symbols in the same subframe occupied by each HARQ feedback information indicated by the configuration signaling includes:
and configuring the HARQ feedback information on one uplink time domain symbol pre-designated by the network node, and configuring the data borne by the physical uplink shared channel on other uplink time domain symbols except the uplink time domain symbol pre-designated by the network node occupied by the HARQ feedback information.
Optionally, in another optional embodiment of the method for configuring information provided in the embodiment of the present invention based on the last optional embodiment, the specified one uplink time domain symbol is a last uplink time domain symbol,
Correspondingly, the configuring the one piece of HARQ feedback information on the one uplink time domain symbol pre-designated by the network node, and configuring the data carried by the one physical uplink shared channel on the other uplink time domain symbols except the one pre-designated by the network node occupied by the HARQ feedback information includes:
and configuring the HARQ feedback information on the last uplink time domain symbol, and configuring the data carried by the physical uplink shared channel on other uplink time domain symbols except the last uplink time domain symbol occupied by the HARQ feedback information.
In the embodiment of the invention, when the terminal transmits one piece of HARQ feedback information and simultaneously transmits one piece of data borne by the physical uplink shared channel through the same subframe, the one piece of HARQ feedback information can be configured in one uplink time domain symbol pre-designated by the network node in the same subframe, and the data borne by the physical uplink shared channel can be configured in other uplink time domain symbols except the one uplink time domain symbol pre-designated by the network node occupied by the HARQ feedback information in the same subframe. For example, when there are 14 uplink time domain symbols in a subframe, one HARQ feedback information is configured on the last uplink time domain symbol, and the data carried by the physical uplink shared channel is configured on the other 13 uplink time domain symbols in the same subframe.
In the embodiment of the present invention, the terminal may also receive the effective time of the configuration signaling in step 101 of the network node configuration. There are three ways to configure the validation time.
The first method is as follows: a system frame number (SFN, system Frame Number) sent by the network node informing the UE of the validation is received.
The second method is as follows: and receiving N subframes or M milliseconds after receiving the configuration signaling, which are sent by the network node and inform the UE, and enabling the configuration signaling to take effect.
Third, the effective time of the configuration signaling is predefined. Specifically, a system frame number for validating the configuration signaling may be predefined.
By configuring the effective time, the ambiguity period between the network node and the user equipment can be reduced or eliminated, the ACK/NACK effectiveness can be improved, and additional ACK/NACK interference or ACK/NACK error detection can be avoided.
In the embodiment of the present invention, the terminal may also receive the validity time (duration) of the configuration signaling in step 101 of the network node configuration. The minimum unit of validity time may be radio frame level (one radio frame 10 ms), e.g., the network node configures that the current configuration signaling is valid for 100 radio frames or 50 radio frames; the minimum unit may also be in the order of milliseconds (ms). And when the valid time is exceeded, namely the configuration signaling is invalid, the UE adopts a default ACK/NACK feedback mode.
In the embodiment of the present invention, the terminal may also receive a release command sent by the network node, where the release command is used to deactivate the configuration signaling in step 101, i.e. indicate that the configuration signaling is invalid. After receiving the release command, the UE may adopt a default ACK/NACK feedback mode. The release command may be RRC signaling, MAC signaling, or physical layer signaling, such as signaling in PDCCH.
Referring to fig. 2, an embodiment of a method for configuring information according to an embodiment of the present invention includes:
201. the network node sends configuration signaling to the terminal, where the configuration signaling is used to instruct the terminal to send at least one HARQ feedback information, where each HARQ feedback information in the at least one HARQ feedback information occupies a part of time domain symbols in the same subframe.
The hybrid automatic repeat request (HARQ, hybrid Automatic Repeat Request) feedback information includes: correct Acknowledgement (ACK) or incorrect Acknowledgement (NACK).
The time domain symbols in the embodiments of the present invention include uplink time domain symbols or slots.
Taking 14 uplink time domain symbols as an example of one subframe, in the embodiment of the present invention, HARQ feedback information only needs to occupy part of uplink time domain symbols in the 14 uplink time domain symbols, and does not need to occupy all uplink time domain symbols, so that other uplink time domain symbols can be used to carry other HARQ feedback information or data carried by PUSCH. Preferably, the uplink time domain symbols occupied by the HARQ feedback information are not more than 7.
The configuration signaling sent by the network node to the terminal is a higher layer signaling. Wherein higher layer signaling (High Layer Signaling) is signaling from higher layers (layers) that is sent more slowly than physical layer signaling, including radio resource control (RRC, radio Resource Control) signaling and medium access control (MAC, media Access Control) signaling, among others. Specifically, the configuration signaling is MAC signaling, or the configuration signaling is dedicated RRC signaling, and the ACK/NACK feedback manner of each UE may be configured separately. The configuration signaling may also be broadcast signaling, which exists in a master information block (MIB, master Information Block) and/or a system information block (SIB, system Information Block), so that the base station can uniformly perform ACK/NACK configuration on UEs in the cell.
202. And the network node receives and analyzes the HARQ feedback information sent by the terminal on part of time domain symbols in the same subframe occupied by each piece of HARQ feedback information indicated by the configuration signaling.
When the terminal transmits a plurality of HARQ feedback information, the HARQ feedback information may be transmitted to different network nodes at the same time or may be transmitted to the same network node. When the plurality of HARQ feedback information are sent to different network nodes and are carried on the same uplink carrier, then the network node receives the plurality of HARQ feedback information sent to different network nodes, but the network node may only parse the HARQ feedback information sent to itself. When the HARQ feedback information is sent to different network nodes and is carried on different uplink carriers, the network nodes can only receive and parse the HARQ feedback information sent to themselves.
In the embodiment of the invention, a configuration signaling is sent to a terminal, wherein the configuration signaling is used for indicating that the terminal sends at least one hybrid automatic repeat request (HARQ) feedback information, and each HARQ feedback information occupies part of time domain symbols in the same subframe; and receiving and analyzing the HARQ feedback information sent by the terminal on part of time domain symbols in the same subframe occupied by each piece of HARQ feedback information indicated by the configuration signaling. Compared with the technical scheme that the UE cannot send the HARQ feedback information to two network nodes at the same time in the prior art, the network node can inform the terminal of sending at least one HARQ feedback information through the configuration signaling to part of time domain symbols in the same subframe, so that the utilization rate of the time domain symbols is improved, and the sending speed of the HARQ feedback information is increased.
Optionally, on the basis of the embodiment corresponding to fig. 2, in another embodiment of the method for configuring information provided by the embodiment of the present invention, the HARQ feedback information includes: correct acknowledgement ACK or incorrect acknowledgement NACK; before the step of sending the configuration signaling to the terminal, the method may further include:
When the terminal is instructed to send one HARQ feedback information, generating the configuration signaling, wherein the configuration signaling is used for indicating one uplink time domain symbol or one appointed time slot, which is pre-appointed by a network node, in the same subframe occupied by the one HARQ feedback information;
when the terminal is instructed to send two pieces of HARQ feedback information, generating the configuration signaling, wherein the configuration signaling is used for indicating different time slots in the same subframe occupied by the two pieces of HARQ feedback information respectively.
In the embodiment of the present invention, when the network node configures to send one HARQ feedback information, the network node may specify which uplink time domain symbol in the same subframe the one HARQ feedback information should be configured in, e.g. specify the last uplink time domain symbol, which is configured in, and of course, this is just an example, and other uplink time domain symbols may also be used. When there are two slots in the same subframe, it may be specified on which slot, such as the first slot or the second slot, the one HARQ feedback information is configured.
When two pieces of HARQ feedback information are to be transmitted, the network node may designate that the two pieces of HARQ feedback information are configured on two different time slots respectively, and define a configuration sequence, for example, a first piece of HARQ feedback information is configured on a first time slot, and a second piece of HARQ feedback information is configured on a second time slot, and of course, the configuration may be reversed, and the terminal is configured completely according to the requirements in the configuration signaling transmitted by the base station.
Optionally, in another optional embodiment of the method for configuring information provided by the embodiment of the present invention on the basis of the optional embodiment corresponding to fig. 2, when the HARQ feedback information occupies one uplink time domain symbol pre-specified by a network node in the same subframe, the HARQ feedback information is indicated by a cyclic shift value of a physical uplink control channel PUCCH sequence.
In the embodiment of the invention, different cyclic shift values indicate different ACK/NACK states. The cyclic shift value and the ACK/NACK state are in one-to-one correspondence. The ACK/NACK state may include only two states, ACK and NACK; the dimensions of subframes and/or unit carriers may also be introduced, including ACK and NACK states on different subframes and/or different unit carriers. Specifically, the base station may inform the UE of a cyclic shift value for indicating an ACK/NACK state through higher layer signaling or physical layer signaling, or a standard predefines a cyclic shift value for indicating an ACK/NACK state. For example, the cyclic shift value α=0 represents ACK, α=m SC The/2 represents NACK, or the cyclic shift value α=0 represents NACK, α=m SC And/2 represents ACK.
PUCCH sequence length M SC The sequence length of the PUCCH may be predefined by the standard or may be signaled by the network node to the UE via higher layer signaling. Preferably, the sequence length M of PUCCH SC The frequency resource can be multiplexed with the existing PUCCH format at 12, because the PUCCH designed by the present invention can be made orthogonal to the sequence employed by the existing PUCCH format.
Optionally, on the basis of the embodiment corresponding to fig. 2 and the two alternative embodiments corresponding to fig. 2, in another embodiment of the method for configuring information provided by the embodiment of the present invention, before receiving the at least one HARQ feedback information sent by the terminal, the method may further include:
a first reserved resource configured to carry the at least one HARQ feedback information sent by the terminal;
transmitting a first reserved resource configuration signaling to the terminal, wherein the first reserved resource configuration signaling indicates a time period of the first reserved resource and a subframe offset in each time period;
correspondingly, the receiving the at least one HARQ feedback information sent by the terminal includes:
and receiving the at least one HARQ feedback information sent by the terminal on the first reserved resource.
In the embodiment of the invention, the network node configures a first reserved resource for transmitting the HARQ feedback information for the terminal, then notifies the terminal in a mode of the first reserved resource configuration signaling, and then the terminal can transmit the at least one HARQ feedback information on the first reserved resource. Reserved resources mean resources reserved by the network node for transmitting HARQ feedback information to the UE. Because the scheduling of PDSCH is dynamic, the ACK/NACK feedback for PDSCH is also dynamic. When the feedback of the HARQ feedback information is needed, the UE sends the HARQ feedback information on one subframe allocated to the reserved resource, and when the feedback of the HARQ feedback information is not needed, the UE does not send the HARQ feedback information on the reserved resource, namely, some subframes allocated to the reserved resource are empty. Specifically, when the first reserved resource is a time period and a subframe offset in each time period, the terminal may transmit the at least one HARQ feedback information at a time point of the time period and the subframe offset in each time period, and the network node may receive the at least one HARQ feedback information at a time point of the time period and the subframe offset in each time period. For example, the time period for which the network node configures the reserved resources is 10ms (milliseconds) and may be occupied in the last subframe of every 10 ms.
The scheduling of PDSCH is dynamic and thus the ACK/NACK feedback of PDSCH is also dynamic. If ACK/NACK is sent on part of uplink time domain symbols of one subframe at any time, when only one HARQ feedback information is sent, the uplink time domain symbols are remained, and resource waste is caused. In this embodiment, the network node pre-configures reserved resources through higher layer signaling, so as to reduce the possibility of resource waste.
Optionally, in another embodiment of the method for information configuration provided in the present invention based on the two alternative embodiments corresponding to fig. 2, before receiving the at least one HARQ feedback information sent by the terminal when the HARQ feedback information occupies one uplink time domain symbol specified in the same subframe, the method further includes:
a second reserved resource configured to carry the at least one HARQ feedback information sent by the terminal, wherein a subframe occupied by the reserved resource is a subframe configured to a cell specific sounding reference signal (SRS, sounding Reference Signal);
correspondingly, the receiving the at least one HARQ feedback information sent by the terminal includes:
and receiving the at least one HARQ feedback information sent by the terminal on the second reserved resource.
In the embodiment of the present invention, the subframe occupied by the second reserved resource is a full set or a subset of subframes occupied by the specific sounding reference signal configured to the cell. When the network node is a full set, the network node does not need to inform the terminal that the network node is configured to the subframe of the reserved resource, and because the subframe occupied by the second reserved resource is the same as the subframe occupied by the cell specific sounding reference signal, the terminal can determine that the network node is configured to the subframe of the second reserved resource by acquiring the subframe configured by the network node to the cell specific sounding reference signal. When the sub-set is the sub-set, the network node needs to inform the UE that the sub-frame occupied by the reserved resource is a partial sub-frame of the sub-frame occupied by the cell specific sounding reference signal. In this way, the terminal may send the at least one HARQ feedback information in the subframe allocated to the reserved resource, and the network node may receive the at least one HARQ feedback information in the subframe allocated to the second reserved resource. The subframe occupied by the cell-specific SRS refers to a subframe reserved by the network node for UEs in the whole cell for transmitting SRS.
Optionally, in another embodiment of the method for configuring information provided by the embodiment of the present invention based on the embodiment corresponding to fig. 2 and the two alternative embodiments corresponding to fig. 2, before receiving the at least one HARQ feedback information sent by the terminal when the HARQ feedback information occupies one or two uplink time domain symbols specified in the same subframe, the method further includes:
A third reserved resource configured to carry the at least one HARQ feedback information sent by the terminal;
transmitting a second reserved resource configuration signaling to the terminal, wherein the second reserved resource configuration signaling indicates that the third reserved resource is positioned in an uplink pilot time slot UpPTS in a Time Division Duplex (TDD) system;
correspondingly, the receiving the at least one HARQ feedback information sent by the terminal includes:
and receiving the at least one HARQ feedback information sent by the terminal on the third reserved resource.
In the embodiment of the present invention, when in the TDD system, the third reserved resource configured by the network node is located in the uplink pilot time slot UpPTS, so that the terminal may send the at least one HARQ feedback information in the uplink pilot time slot UpPTS, and the network node may also receive the at least one HARQ feedback information in the uplink pilot time slot UpPTS.
Optionally, in another embodiment of the method for configuring information provided in the foregoing first alternative embodiment of fig. 2, when the terminal is instructed to send one piece of HARQ feedback information and send data carried by one physical uplink shared channel through the same subframe, the configuration signaling is generated, where the configuration signaling is used to instruct the data carried by the physical uplink shared channel to occupy other uplink time domain symbols in the same subframe except for the specified one uplink time domain symbol occupied by the HARQ feedback information.
In the embodiment of the present invention, when the terminal is instructed to send one piece of HARQ feedback information and send one piece of data carried by the physical uplink shared channel through the same subframe, the one piece of HARQ feedback information may be configured in one uplink time domain symbol pre-designated by the network node in the same subframe, and the data carried by the physical uplink shared channel may be configured in other uplink time domain symbols in the same subframe except the one uplink time domain symbol pre-designated by the network node occupied by the HARQ feedback information. For example, when there are 14 uplink time domain symbols in a subframe, one HARQ feedback information is configured on the last uplink time domain symbol, and the data carried by the physical uplink shared channel is configured on the other 13 uplink time domain symbols in the same subframe.
In the embodiment of the present invention, the network node may also configure the effective time of the configuration signaling in step 201. There are three ways to configure the validation time.
The first method is as follows: the network node informs the UE of the validated system frame number (SFN, system Frame Number).
The second method is as follows: the network node informs the UE that the configuration signaling is valid after N subframes or M milliseconds after receiving the configuration signaling.
Third, the effective time of the configuration signaling is predefined. Specifically, a system frame number for validating the configuration signaling may be predefined.
By configuring the effective time, the ambiguity period between the network node and the user equipment can be reduced or eliminated, the ACK/NACK effectiveness can be improved, and additional ACK/NACK interference or ACK/NACK error detection can be avoided.
In the embodiment of the present invention, the network node may also configure the validity time (duration) of the configuration signaling in step 201.
The network node configures the validity time of the configuration signaling in step 201, and after the validity time is exceeded, the configuration signaling is disabled. The network node may inform the UE of the validity time of the configuration signaling or may predefine the validity time of the configuration signaling by a standard.
Specifically, after exceeding the validity time, the configuration signaling failure includes:
when the moment distance of the last successful receiving of the physical layer downlink control channel (Physical Downlink Control channel, PDCCH) or the physical downlink shared channel (Physical Downlink Share Channel, PDSCH) by the UE exceeds the effective time from the moment at present, the configuration signaling is invalid; and/or the number of the groups of groups,
and when the moment of receiving the configuration signaling exceeds the effective time from the current moment, the configuration signaling is invalid.
The minimum unit of validity time may be radio frame level (one radio frame 10 ms), e.g., the network node configures that the current configuration signaling is valid for 100 radio frames or 50 radio frames; the minimum unit may also be in the millisecond (ms) order, e.g., the network node configures the current configuration signaling to be valid for 100ms or 1000 ms. When the valid time is exceeded, i.e. the configuration signaling is invalid, the UE adopts a default ACK/NACK feedback mode, for example, HARQ feedback information in the same subframe is configured only to the same network node.
The base station sends a release command to the UE, which is used to deactivate the configuration signaling in step 201, i.e. to indicate that the configuration signaling is invalid. After receiving the release command, the UE may adopt a default ACK/NACK feedback mode. The release command may be RRC signaling, MAC signaling, or physical layer signaling, such as signaling in PDCCH.
For easy understanding, the following describes the procedure of the method for information configuration in the embodiment of the present invention, taking two application scenarios as examples:
referring to fig. 3A, fig. 3A is a format of a network node configured for a terminal to send one HARQ feedback information, where the one HARQ feedback information occupies only a last uplink time domain symbol in one subframe, so that when the terminal configures the one HARQ feedback information, the terminal only needs to configure the one HARQ feedback information on the last uplink time domain symbol in fig. 3A, and send the one HARQ feedback information to the network node, and after receiving the one HARQ feedback information, the network node can parse the HARQ feedback information from the last uplink time domain symbol in the same subframe shown in fig. 3A.
Referring to fig. 3B, fig. 3B is a format of a network node configured for a terminal to send one HARQ feedback information, where the one HARQ feedback information occupies only a last time slot in a subframe, so that when the terminal configures the one HARQ feedback information, the terminal only needs to configure the one HARQ feedback information on the last time slot in fig. 3B, and send the one HARQ feedback information to the network node, and after receiving the one HARQ feedback information, the network node can parse the HARQ feedback information from the last time slot in the same subframe shown in fig. 3B.
Referring to fig. 4A, fig. 4A is a format of a network node configured for a terminal when two HARQ feedback information is transmitted, where the two HARQ feedback information occupies two time slots in one subframe, so that when the terminal configures the two HARQ feedback information, the terminal only needs to configure the two HARQ feedback information on the two time slots in fig. 4A, and send the two HARQ feedback information to the network node and another network node. Assuming that the HARQ feedback information of the network node is carried in the last slot, the network node may receive and parse the HARQ feedback information sent to the network node from the last slot in the same subframe as shown in fig. 4A. The two HARQ feedback information may be carried on different frequency carriers, but may also be carried on the same frequency carrier.
Referring to fig. 4B, fig. 4B is a format when a network node sends one HARQ feedback information configured for a terminal and simultaneously sends data carried by one physical uplink shared channel, where one HARQ feedback information occupies the last uplink time domain symbol, and one data carried by one physical uplink shared channel occupies the remaining other uplink time domain symbols. The data carried by one HARQ feedback information and one physical uplink shared channel may be carried on carriers of different frequencies, or may be carried on carriers of the same frequency.
