Description

Information transmission method, network equipment and terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an information transmission method, a network device, and a terminal.

Background

In the prior art, NR (New Radio, New Radio or 5G) supports Semi-Persistent Scheduling (SPS), that is, a network side performs SPS configuration on a user through a high-level signaling SPS-Config and activates DCI (Downlink Control Information), so as to achieve the purpose of periodically allocating Downlink resources to the user, that is, "Scheduling once and using many times".

NR supports repeated/aggregated transmission, whether scheduled for SPS or dynamically scheduled: the network side configures a pdsch-aggregation factor (configurable 1, 2,4, 8) through high-level signaling, and a UE (User Equipment or terminal) repeatedly transmits the same TB (Transmission Block) in consecutive pdsch-aggregation factor downlink slots.

In the prior art, there is also a case that NB-IoT (Narrow Band Internet of Things) and NR mtc (large-scale Internet of Things) in the 4G stage are mainly applied to connection of large-scale Internet of Things, and the main design targets are low cost, low power consumption, coverage enhancement and large connection. Wherein the coverage enhancement is mainly achieved by repetition in the NB-IoT stage, with a maximum number of repetitions up to 2048.

In the prior art, there is also a case of PDCCH (Physical downlink control channel): the Downlink Control Information (DCI) is used for scheduling Physical Downlink Shared Channel (PDSCH) transmission; the PDSCH is used for carrying data; a PUCCH (Physical Uplink Control Channel) is used to carry HARQ-ACK (Hybrid automatic repeat request acknowledgement) information, which indicates whether the terminal receives a correct PDSCH.

The above prior art has the following problems:

for some vertical industry (such as agriculture and industry) equipment (such as intelligent well lid monitoring, crop remote monitoring and the like), the existing design can not meet the coverage requirement of the equipment, and the coverage needs to be enhanced;

if the coverage is enhanced, the method mainly depends on the means of repeated transmission; the configuration of the repeated transmission times generally needs to ensure the coverage requirement of the terminal under any condition (for example, intelligent well lid monitoring needs to meet the coverage requirement when the motor vehicle is shielded); the repeated transmission not only occupies a large amount of wireless resources, but also can increase the power consumption of users;

therefore, for PDSCH repeated transmission, when the terminal receives correctly in advance, it is desirable to perform an operation of early termination, that is, PDSCH early termination, so that not only can the remaining downlink resources be released, but also the terminal can stop receiving PDSCH, thereby saving power consumption;

the reliability requirement can be met by supposing that single PUCCH transmission is carried out, the PDSCH needs to be repeated for K times, and in order to terminate the PDSCH in advance, the UE needs to report HARQ-ACK information to the PDSCH every time, which means that PUCCH resources are reserved for each PDSCH, and the method is equivalent to the saving of using PUCCH resource overhead to replace PDSCH resources;

however, if the PDSCH needs to be repeatedly transmitted K times to meet the coverage requirement, theoretically, a single PUCCH transmission cannot meet the reliability/coverage requirement, the PUCCH also needs to be repeated, and if the PUCCH is repeated M times to meet the requirement, and the PDSCH is repeated K times to meet the requirement, the PDSCH resources are saved by terminating the PDSCH in advance, at most, M × K PUCCH resources need to be reserved, and the PUCCH resource overhead is large.

the network side determines through a high-level signaling configuration mode, or determines through a pre-agreed mode, or configures a plurality of P values through a protocol predefined mode, and the DCI selects one of the P values through the first indication information;

The terminal receives a high-level signaling and/or a physical layer control signaling sent by a network side, determines the PDSCH resource and the PUCCH resource, and specifically comprises the following steps:

1) determining a repetition pattern of the PDSCH according to the first indication information and/or the second timing information: the method comprises the steps of repeating times K, grouping information P and time sequences among different PDSCH groups;

2) determining a repetition pattern of the PUCCH according to the second indication information and/or the first timing information: the method comprises the repeated transmission times Q of the PUCCH after each group of K/P PDSCHs, the repeated transmission times M of the PUCCH after all K PDSCHs are transmitted, and the time sequence from the PDSCH to the PUCCH;

3) determining PUCCH resources: and determining the PUCCH resource ID which is repeatedly transmitted according to one or more of high-level control signaling, physical-layer downlink control signaling and protocol pre-agreement sent by the base station.

The repeated transmission method of the terminal HARQ-ACK comprises the following steps:

state of HARQ-ACK: there are two states for the middle K-1 HARQ-ACK: ACK and DTX

There are three states for the last M HARQ-ACKs: ACK, NACK, and DTX (Discontinuous Transmission);

the HARQ-ACK sending method comprises the following steps: PUCCH before K PDSCH transmissions are completed (i.e., if the terminal completes correct demodulation before K PDSCH transmissions are completed): before a terminal correctly demodulates a PDSCH, all PUCCHs are not transmitted, and after the terminal firstly demodulates the correct PDSCH, ACK is transmitted on continuous M PUCCH resources from the first PUCCH resource after the PDSCH; alternatively, the ACK is transmitted until the PDSCH transmitted by the base station cannot be detected.

PUCCH after K PDSCH transmissions are completed (i.e., the terminal has not completed correct demodulation before K PDSCH transmissions are completed): transmitting ACK or NACK based on the demodulation results for the K PDSCHs.

And after the network side detects the ACK information sent by the terminal, the sending of the PDSCH is terminated in advance.

In the above embodiments of the present invention, as shown in fig. 2, the terminal continuously sends N PDCCHs for carrying DCI that schedules K PDSCHs and M PUCCHs; and in order to prevent the base station from finding the problem of missed detection of the PDCCH after the transmission of all PDSCHs is finished, M PUCCH resources are reserved after the transmission of the PDCCH for N times is finished, and HARQ-ACK information whether the N PDCCHs are correctly received is carried.

For each PDSCH transmission, one PUCCH resource is reserved: if the UE receives the correct PDSCH based on the PUCCH, the HARQ-ACK is reported, and if the UE does not receive the correct PDSCH, nothing is sent.

The UE continuously transmits the ACK information for M times on M PUCCH resources after receiving the correct PDSCH, and does not judge the transmission state of the HARQ-ACK based on whether the PDSCH receives the HARQ-ACK correctly. The base station can perform power accumulation on the M PUCCH resources, so that the reliability of the PUCCH is improved, and the waste of a large amount of PUCCH resources is avoided.

After the K PDSCHs, M PUCCH resources need to be additionally reserved, so that the HARQ-ACK information (including ACK and NACK) is reported when the terminal receives the correct PDSCH based on the K PDSCHs or the terminal still cannot demodulate the correct PDSCH based on the K PDSCHs.

Further, in order to adapt to some semi-static frame structure configurations with a long uplink and downlink switching period, K PDSCH transmissions may be divided into P segments, and K/P PUCCH resources are reserved for every K/P PDSCH transmissions, as shown in fig. 3, so that PUCCH resource waste may be further avoided.

Further, in order to match the quality of uplink and downlink channels, theoretically, the more the PDSCH is received, the higher the transmission accuracy probability is, the resource reservation of the PUCCH may be performed in a non-uniform manner, and on the basis of the above steps, the number of P-segment PUCCH resources may be non-uniformly distributed, and may be in an increased state, such as 2,4,8 …, while the PDSCH is uniformly distributed.
