Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to an information sending method and a terminal.
Background
Since the Unlicensed Band is shared by multiple Radio Access Technologies (RATs), such as Wi-Fi, radar, L TE-L AA, etc., in some countries or regions, the Unlicensed Band must be used according to regulatory rules to ensure that all devices can fairly share the resource, such as a pre-transmission listening Channel (L Before Talk, L BT), a Maximum Channel Occupancy Time (MCOT), etc.
For an unlicensed communication system (NR-U), in a same Physical Downlink Control Channel (PDCCH) detection occasion (monitoring occasion), a network device may schedule Transmission in multiple Transmission Time Intervals (TTIs) using multiple uplink grants (U L grant), each uplink grant schedules Transmission in a single TTI, or may schedule Transmission in multiple TTIs simultaneously using a single uplink grant, each TTI corresponds to a different Transport Block (TB) and hybrid automatic Repeat reQuest (HARQ) process identifier ID., and for uplink Transmission (i.e., uplink Multi-TTI Transmission), may schedule the UE to detect an idle condition of a wireless Channel at multiple Time positions within a certain TTI duration, and determine whether the wireless Channel can be successfully accessed based on a detection result, thereby increasing a probability of successfully accessing the wireless Channel.
Currently, in order to perform uplink Multi-TTI transmission, a terminal may puncture (punture) a local symbol of a corresponding TTI based on a channel occupancy condition, so as to access a radio channel by using a multiple starting point (multiple starting point); and/or the terminal may perform access to a radio channel based on micro slots (mini-slots), where each mini-slot corresponds to a different HARQ process.
However, when puncturing partial symbols of a TTI based on a channel occupation situation, transmission performance may deteriorate or performance may be unstable, when a mini-slot is introduced, a large number of HARQ processes are required, and in some cases, there are problems of unnecessary retransmission scheduling and insufficient HARQ processes, which results in poor transmission performance of the existing uplink Multi-TTI transmission.

Referring to fig. 1, fig. 1 is a flowchart of an information sending method according to an embodiment of the present invention, where the method is applied to a terminal, and as shown in fig. 1, the method includes the following steps:
step 101: the indication information is sent on a target TTI of the Multi-TTI transmission.
Wherein the indication information is used to indicate information related to the Multi-TTI transmission. The Multi-TTI transmission is an uplink Multi-TTI transmission.
When the terminal transmits the indication information in the target TTI, the terminal may transmit the indication information in a puncturing (puncturing) or rate matching (rate matching) manner based on the number of bits of the indication information. For example, when the bit number of the indication information is 1 bit, the indication information may be transmitted in a puncturing manner; and when the bit number of the indication information is a plurality of bits, the indication information can be transmitted by adopting a rate matching mode.
The information sending method of the embodiment of the invention sends the indication information on the target TTI of the Multi-TTI transmission, wherein the indication information is used for indicating the relevant information of the Multi-TTI transmission, and can realize information interaction between the terminal and the network equipment for channel occupation and data transmission conditions when uplink Multi-TTI transmission is carried out, thereby improving the decoding performance of the corresponding PUSCH, avoiding unnecessary HARQ process occupation and retransmission scheduling, reducing the probability of insufficient HARQ process and improving the transmission performance of the uplink Multi-TTI transmission. Further, the network device may determine whether the corresponding PUSCH actually transmits (i.e., occupies a wireless channel) by activating and detecting the indication information, so as to more accurately determine the time when the terminal actually starts uplink transmission.
In this embodiment of the present invention, optionally, the target TTI may be any one of the following:
the first slot of the actual transmission;
the first minislot of the actual transmission.
Wherein, the first slot of the actual transmission can be understood as: a first slot scheduled, successfully accessed to a wireless channel and transmitted; or the first slot configured, successfully accessing the radio channel and transmitting. The first mini-slot of this actual transmission can be understood as: a first mini-slot scheduled, successfully accessed to a wireless channel and transmitted; or the first mini-slot configured, successfully accessing the radio channel and transmitting.
Optionally, the step 101 may include:
transmitting the indication information on a designated symbol;
wherein the designated symbol is one or a preset number of symbols in the actually transmitted symbol set of the target TTI. That is, the designated symbol is one or a preset number of symbols in the symbol set that the target TTI must transmit when transmission actually occurs. For example, the designated symbol may be selected as the last symbol of the target TTI or the last predetermined symbol of the target TTI.
In this way, the probability of successful detection of the indication information by the network device can be improved.
Optionally, the information related to the Multi-TTI transmission may include at least one of:
actual occupancy information of the wireless channel; for example, the location where the PUSCH transmission actually starts;
information of rate matching;
an identity of an occupied HARQ process; for example, the identifier of the HARQ process occupied by the actually performed PUSCH transmission;
conversion information from mini-slot to slot;
mini-slot merging information.
In the embodiment of the present invention, based on different scheduling or configuration conditions of the network device, the related information of Multi-TTI transmission indicated by the terminal may include different contents. Optionally, when the mini-slot is not used for the Multi-TTI transmission and a Multi-start position is used in a slot in the Multi-TTI transmission, the information related to the Multi-TTI transmission may include at least one of the following:
a location where the PUSCH transmission actually starts;
information of rate matching;
and identifying the HARQ process occupied by the actually performed PUSCH transmission.
Optionally, when at least a preset portion of the Multi-TTI transmission adopts a mini-slot and a single slot or multiple start positions are not adopted in the mini-slot, the related information of the Multi-TTI transmission may include at least one of the following:
conversion information from mini-slot to slot;
merging information of mini-slot;
and identifying the HARQ process occupied by the actually performed PUSCH transmission.
Optionally, the information related to the Multi-TTI transmission may include any one of:
all actual transmission in the slot of the current target TTI adopts a preset mini-slot length, and the subsequent slots of the slot of the current target TTI adopt slot granularity transmission; wherein the subsequent slot is configured or scheduled for transmission with a mini-slot granularity; this corresponds to the mini-slot to slot conversion information described above;
the time granularity of the next actual transmission of the current target TTI;
merging information of mini-slot in next actual transmission of the current target TTI;
the current target TTI adopts a preset mini-slot length, the rest symbols in the slot where the current target TTI is located are combined into a single mini-slot for transmission, and the subsequent slot of the slot where the current target TTI is located adopts slot granularity transmission; wherein the length of the remaining symbols is greater than the pre-agreed mini-slot length, and the subsequent slots are configured or scheduled for transmission with mini-slot granularity; this corresponds to the mini-slot to slot conversion information and the mini-slot merge information.
It should be noted that, for the mini-slot merging situation, the terminal may determine how to merge the corresponding mini-slots based on the actual occupation situation of the wireless channel, and indicate the merging information of the mini-slots through the indication information sent on the target TTI, so that the network device can know the merging information.
In this embodiment of the present invention, when the target TTI is the first slot of actual transmission or the first mini-slot of actual transmission, the information related to Multi-TTI transmission includes: identification of HARQ process occupied by actually performed first PUSCH transmission.
Further, when the information related to the Multi-TTI transmission includes an identification of a HARQ process occupied by a first PUSCH transmission actually performed, the method may further include any one of:
transmitting first HARQ process indication information on a last PUSCH of an actual transmission in the Multi-TTI transmission; wherein, the first HARQ process indication information is used for indicating the identifier of the HARQ process occupied by the last PUSCH transmission;
transmitting second HARQ process indication information on a PUSCH of each actual transmission in the Multi-TTI transmissions; wherein, the second HARQ process indication information is used to indicate an identifier of a HARQ process occupied by a corresponding PUSCH transmission.
Therefore, by means of the HARQ process indication information, the HARQ processes corresponding to all practically occurring PUSCH transmissions can be prevented from being judged wrongly when the network equipment decodes the information carried on the first PUSCH transmission wrongly.
Further, when the information related to the Multi-TTI transmission includes an identification of a HARQ process occupied by a first PUSCH transmission actually performed, the method may further include:
mapping the data of the first HARQ process to a first PUSCH of actual transmission and sending the data; wherein, the identifier of the first HARQ process may be indicated by Downlink Control Information (DCI);
and determining the identifier of the HARQ process corresponding to the subsequent TTI of the target TTI according to the identifier of the first HARQ process and a predefined mapping rule, and transmitting the data of the corresponding HARQ process on each subsequent TTI. It is to be appreciated that the subsequent TTI can be selected as a slot or a mini-slot.
Compared with the prior art, the terminal can flexibly select the corresponding HARQ process according to the actual channel acquisition condition, thereby avoiding unnecessary HARQ process occupation and retransmission scheduling.
Optionally, when the target TTI is the first slot actually transmitted or the first mini-slot actually transmitted, if the relevant information of the Multi-TTI transmission does not include the identifier of the HARQ process occupied by the first PUSCH transmission actually performed, the method may further include:
determining an identifier of an HARQ process indicated in the DCI as a first identifier, wherein the first identifier is an identifier of the HARQ process occupied by the actually performed first PUSCH transmission;
mapping the data of the HARQ process corresponding to the first identifier to a first PUSCH for actual transmission and sending the data;
and determining the identifier of the HARQ process corresponding to the subsequent TTI of the target TTI according to the first identifier and a predefined mapping rule, and transmitting the data of the corresponding HARQ process on each subsequent TTI.
In the embodiment of the invention, the network equipment can indicate the terminal to adopt a lower code rate to the indication information on the target TTI or occupy more resources so as to improve the decoding reliability.
Optionally, a ratio of a first code rate and a second code rate adopted by the indication information is lower than a first preset value, and the second code rate is a code rate of PUSCH transmission in the target TTI.
Optionally, the indication information occupies more resources than a second preset value.
It should be noted that the first preset value and the second preset value may be preset based on actual situations, and the embodiment of the present invention does not limit this.
Therefore, the reliability of the network equipment for decoding the indication information can be improved by adopting a lower code rate and/or occupying more resources to send the indication information.
The present invention will be described in detail with reference to specific examples.
Example one
In a first embodiment, a mini-slot is not used for Multi-TTI transmission of a UE, and multiple start positions are used in slots in the Multi-TTI transmission. When Multi-TTI transmission is performed, the UE may send indication information on a designated symbol, where the indication information is used to indicate information related to Multi-TTI transmission, and the designated symbol may be selected from one or some symbols between a last available starting position in a slot (if multiple starting positions are not used in the slot, the starting position is a starting time of the slot) and an ending time of the slot, and may generally directly use the last 1 or last preset symbols in the range.
Based on the scheduling indication of the base station gNB, the following two scenarios may exist in the present embodiment:
scene 1-1: multiple start positions are used in each slot of the schedule
Assuming that the gNB indicates that the UE is in scheduled N1(N1 > 1) slots, and before successfully accessing the wireless channel, accessing the wireless channel in a multi-starting-position mode in each slot; once the UE has successfully accessed the radio channel, the radio channel is continuously occupied during this time range, starting from the access time until the end time of the scheduled slots (assuming that the scheduled slots are continuous in time).
At this time, the UE may send the indication information on the last symbol or the last preset symbol of the first slot that is actually transmitted; the indication information may be used to indicate one or more of the following:
(1) where the PUSCH transmission actually starts.
Wherein, assuming that the indication information occupies n bits, at most 2 can be indicatednThe starting position here may be considered to correspond to the starting position when multiple starting positions are indicated in DCI, so that the network side and the terminal side have a consistent understanding for the specific symbol positions corresponding to the starting positions. This situationThen, the UE may consider rate matching from a symbol position where PUSCH transmission actually starts to improve decoding performance of the PUSCH, that is, ensure that the initial part of the coding sequence corresponding to the redundancy version can be actually transmitted, at this time, based on a data preparation condition, the tail of the coding sequence may be truncated to ensure that the length of the coding sequence actually transmitted matches with the number of actually available symbols or the number of Resource Elements (REs); alternatively, the UE may perform rate matching according to the scheduled symbol set, and then leave the coded sequence portion corresponding to the symbol that does not actually occupy the channel as an unused code sequence portion (i.e., similar to the downlink channel) for non-transmission. The specific method used by the UE for transmission may be predetermined (protocol specification or higher layer configuration), or may be indicated together with the indication information.
(2) The ID of the HARQ process occupied by the actually performed first PUSCH transmission.
In this case, the UE may map the data of the prepared first HARQ process (the ID of this HARQ process may be indicated by DCI) to the first PUSCH transmission actually transmitted based on the delay required for preparing the data, determine the ID of the HARQ process corresponding to the subsequent slot based on the ID of the first HARQ process and a predefined mapping rule, and transmit the data of the corresponding HARQ process in the subsequent slot. Compared with the prior art, the method has the advantages that the UE can flexibly select the corresponding HARQ process according to the actual channel acquisition condition, so that unnecessary HARQ process occupation and retransmission scheduling are avoided.
In one embodiment, when the indication information does not indicate an ID of an HARQ process occupied by a first PUSCH transmission actually performed, the gNB and the UE may agree that the HARQ process indicated in the DCI is the HARQ process occupied by the first PUSCH transmission actually performed (i.e., the first HARQ process); the UE may determine the ID of the HARQ process corresponding to the subsequent slot based on the ID of the first HARQ process and the predefined mapping rule, and transmit data of the corresponding HARQ process in the subsequent slot. Thus, the indication information allows the gNB to more reliably detect the first PUSCH transmission actually performed with lower complexity.
In one embodiment, when the indication information indicates an ID of an HARQ process occupied by actually performed first PUSCH transmission, in order to avoid that the gNB erroneously decodes information carried in the first PUSCH transmission, and erroneously determines HARQ processes corresponding to all actually occurring PUSCH transmissions, at least one of the following may be further employed:
1) the gNB indicates the UE to adopt a lower code rate or occupy more resources aiming at the indication information, so that the decoding reliability is improved;
2) the UE sends HARQ process indication information on the last PUSCH of actual transmission, wherein the HARQ process indication information is used for indicating the ID of the HARQ process occupied by the last PUSCH transmission (namely the PUSCH transmission corresponding to the last slot); in this way, if the ID of the HARQ process occupied by the last PUSCH transmission determined by the gNB based on the ID of the HARQ process occupied by the actually performed first PUSCH transmission and the predefined mapping rule is not consistent with the ID of the HARQ process occupied by the last PUSCH transmission indicated by the HARQ process indication information, it may indicate that there is a decoding error. At this time, the gNB may discard all data received by all HARQ processes indicated by the DCI within the scheduled TTIs, and subsequently schedule retransmissions for the HARQ processes.
3) And the UE sends HARQ process indication information on each practically transmitted PUSCH, wherein the HARQ process indication information is used for indicating the identifier of the HARQ process occupied by the corresponding PUSCH transmission.
Scenes 1-2: using multiple starting positions in the first part of scheduling slot
Assuming that the gNB indicates that the UE is in scheduled N1(N1 > 1) slots, before successfully accessing the radio channel, the radio channel is accessed in a multi-start position manner in the first M1(M1< N1, and M1 ≧ 1) slots, and the radio channel is attempted to be accessed at the start time of the slot in the remaining N1-M1 slots; once the UE successfully accesses the radio channel, the radio channel is continuously occupied until the end time of the N1 slots.
The difference from scenario 1-1 at this time is that since only slot-granularity radio channel access is supported, when it is determined that the first slot that successfully accesses the radio channel and performs transmission does not adopt multiple start positions, the UE does not need to indicate a position where PUSCH transmission actually starts.
Example two
In the second embodiment, the first part of Multi-TTI transmission for a UE is based on mini-slots, the subsequent part is based on slots, and no multiple starting positions are adopted within a single mini-slot or slot. The Multi-TTI transmission in this embodiment may be scheduled by DCI or may be pre-configured. When Multi-TTI transmission is performed, the UE may send indication information on a designated symbol, where the indication information is used to indicate related information of Multi-TTI transmission, and the designated symbol may be selected as a certain symbol or certain symbols located in a certain slot or a certain mini-slot duration defined by a pre-agreed slot or mini-slot boundary in the scheduling DCI or the pre-configured Grant by the gNB and the UE, and the last 1 or last preset symbol in the range may be generally used directly.
Based on the scheduling or configuration indication of the gNB, the present embodiment may have the following two scenarios:
scene 2-1: the very beginning of the actual transmission is based on the mini-slot
Assuming that the gNB indicates that the UE is within N2(N2 > 1) slots scheduled or configured, attempting to access the radio channel within each slot with a granularity of mini-slots before successfully accessing the radio channel; once the UE successfully accesses the wireless channel, the UE transmits in the first M2 slots (M2< N2, and M2 ≧ 1) including the slot where the access channel is located, with the requirement of ensuring that all actual transmissions are within the scheduled or configured range of N2 slots, otherwise only to the end time of the scheduled or configured N2 slots, at the granularity of mini-slots, and then (if there are remaining scheduled or configured N2 slots) transmits in the remaining slots at the granularity of slots, and continuously occupies the wireless channel in this time range.
At this time, the UE may send the indication information on the last symbol or the last preset symbol of the first mini-slot that is actually transmitted; the indication information may be used to indicate one or more of the following:
(1) conversion information from mini-slot to slot, and/or merging information of mini-slot
For example, the UE may send 1-bit indication information indicating one of the following two cases:
the method comprises the steps that a current mini-slot (for sending indication information) adopts a preset mini-slot length (such as DCI indication or configuration Grant), remaining symbols (if the remaining symbols exist, and the symbol length of the remaining symbols is more than the preset mini-slot length) in the slot where the current mini-slot is located are combined into a single mini-slot for transmission, and a subsequent slot (configured or scheduled to adopt mini-slot granularity transmission) of the slot where the current mini-slot is located starts from the next slot of the slot where the current mini-slot is located, and transmission of slot granularity is adopted;
all actual transmissions in the slot where the current mini-slot (which sends the indication information) is located, and actual transmissions in subsequent M2-1 slots (which are limited to the number of slots actually allowed to be transmitted based on the radio channel occupancy in the scheduled or configured N2 slots) adopt a pre-agreed mini-slot length (such as DCI indication or configuration Grant), and subsequent slots of these slots (which are configured or scheduled to adopt mini-slot granularity transmissions) adopt slot granularity transmissions.
It can be understood that if the bit number of the indication information is more than 1 bit, the slot/mini-slot mode adopted can be more specifically indicated, for example, whether a mini-slot is adopted in a certain slot or not can be indicated.
For the case that Multi-TTI transmission is configured in advance, because each transmission already carries UCI, the indication information carried in each transmission may only indicate mini-slot transmission or merging information of the next transmission, such as mini-slot merging information corresponding to the next transmission, or convert to slot-based transmission.
(2) The ID of the HARQ process occupied by the actually performed first PUSCH transmission.
In this case, Multi-TTI transmissions are typically scheduled by DCI. The UE may map the prepared data of the first HARQ process to the actually transmitted first PUSCH for transmission based on the time delay required for preparing the data, determine the ID of the HARQ process corresponding to the subsequent slot or the mini-slot based on the identifier of the first HARQ process and the predefined mapping rule, and transmit the data of the corresponding HARQ process in the subsequent slot or the mini-slot. Compared with the prior art, the method has the advantages that the UE can flexibly select the corresponding HARQ process according to the actual channel acquisition condition, so that unnecessary HARQ process occupation and retransmission scheduling are avoided.
In one embodiment, when the indication information does not indicate an ID of an HARQ process occupied by a first PUSCH transmission actually performed, the gNB and the UE may agree that the HARQ process indicated in the DCI is the HARQ process occupied by the first PUSCH transmission actually performed (i.e., the first HARQ process); the UE may determine the ID of the HARQ process corresponding to the subsequent slot or the mini-slot based on the ID of the first HARQ process and the predefined mapping rule, and transmit data of the corresponding HARQ process in the subsequent slot or the mini-slot. Thus, the indication information allows the gNB to more reliably detect the first PUSCH transmission actually performed with lower complexity.
In one embodiment, when the indication information indicates an ID of an HARQ process occupied by actually performed first PUSCH transmission, in order to avoid that the gNB erroneously decodes information carried in the first PUSCH transmission, and erroneously determines HARQ processes corresponding to all actually occurring PUSCH transmissions, at least one of the following may be further employed:
1) the gNB indicates the UE to adopt a lower code rate or occupy more resources aiming at the indication information, so that the decoding reliability is improved;
2) the UE sends HARQ process indication information on the last PUSCH actually transmitted, wherein the HARQ process indication information is used for indicating the ID of the HARQ process occupied by the last PUSCH transmission (namely the PUSCH transmission corresponding to the last slot or mini-slot); in this way, if the ID of the HARQ process occupied by the last PUSCH transmission determined by the gNB based on the ID of the HARQ process occupied by the actually performed first PUSCH transmission and the predefined mapping rule is not consistent with the ID of the HARQ process occupied by the last PUSCH transmission indicated by the HARQ process indication information, it may indicate that there is a decoding error. At this time, the gNB may discard all data received by all HARQ processes indicated by the DCI within the scheduled TTIs, and subsequently schedule retransmission for the HARQ processes.
3) And the UE sends HARQ process indication information on each practically transmitted PUSCH, wherein the HARQ process indication information is used for indicating the identifier of the HARQ process occupied by the corresponding PUSCH transmission.
Scene 2-2: scheduling the very beginning of a transmission is based on mini-slots
Suppose the gNB indicates that the UE is attempting to access and transmit a radio channel with a mini-slot granularity (if not yet successfully accessed) within N2(N2 > 1) slots of the schedule or configuration, within the first M2(M2< N2, and M2 ≧ 1) slots, and within the remaining N2-M2 slots with a slot granularity (if not yet successfully accessed); after successful access to the radio channel, the UE continuously occupies the radio channel until the scheduled or configured end time of N2 slots.
The difference from scenario 2-1 is that when it is determined that the first slot that successfully accesses the wireless channel and performs transmission does not adopt the mini-slot granularity, the UE does not need to indicate mini-slot to slot conversion information or some mini-slot combination information in the indication information.
EXAMPLE III
In the third embodiment, Multi-TTI transmissions of UEs are all based on mini-slots, and multiple starting positions are not adopted within a single mini-slot. The Multi-TTI transmission in this embodiment may be scheduled by DCI or may be pre-configured. When Multi-TTI transmission is performed, the UE may send indication information on a designated symbol, where the indication information is used to indicate related information of Multi-TTI transmission, and the designated symbol may be selected as a certain symbol or certain symbols within a certain mini-slot duration defined by a pre-agreed mini-slot boundary in the scheduling DCI or the pre-configured Grant by the gNB and the UE, and the last 1 or last preset symbol in the range may be generally used directly.
