Description

Processing, transmission method, device, system and storage medium for scheduling information

Technical field

The present invention relates to the field of communications, and in particular, to a method, a device, a system, and a storage medium for processing and transmitting scheduling information.

Background technique

Machine to Machine (M2M) communication is an important subject of the fifth generation of mobile communication technology (5th Generation, 5G), and an important application field for wireless communication in the future. In the M2M project, the 3rd Generation Partnership Project (3GPP) proposed the research of the Narrow Band Internet of Things (NB-IoT) system for the low-cost and low-throughput characteristics of the terminal. The goal of the project is to build a system similar to Long-Term Evolution (LTE) in the 200 kHz band to provide low-throughput wireless communication services for low-cost terminals. In an embodiment, the downlink still uses Orthogonal Frequency Division Multiple Access (OFDMA) technology, and the uplink uses Single-Carrier Frequency Division Multiple Access (SC-FDMA) technology. And try to reuse or simplify the existing functional modules in the LTE system. The subcarrier width increases the subcarrier width of 3.75 KHz in the uplink in addition to the subcarrier width of 15 KHz in the LTE system to further enhance the coverage capability of the uplink of the machine terminal. Currently, relevant technical standards are being studied within the 3GPP International Organization for Standardization.

In a conventional LTE system, different random access channels are distinguished by using different Random Access Radio Network Temporary Identity (RA-RNTI). The user terminal uses the RA-RNTI corresponding to the physical random access channel (PRACH) of the random access preamble to perform a random access response (Random Access Response) in the subsequent random access response window. RAR) reception. In this process, the RA-RNTI used by the user equipment is based on the first subframe number (0 to 9) where the PRACH of the random access preamble is located, and the index of the PRACH in the frequency domain of the random access preamble is transmitted (0 to 5) Calculated. It can be seen that the traditional RA-RNTI calculation method is calculated by using the subframe number of the first subframe occupied by the PRACH that transmits the random access preamble and the frequency index number of the PRACH as parameters, and supports a maximum of 10 ms frame range. Identification of PRACH within.

A random access response message often includes multiple RAR units, and each RAR unit includes a random access preamble identity (RAPID). ) is used to indicate the target user of the RAR unit. If a certain user sends a random access preamble in the foregoing PRACH, it receives the RAR unit with the corresponding RAPID in the random access response message. In summary, in a conventional LTE system, after transmitting a random access preamble, a user must detect all physical downlink control channels (PDCCHs) in a specified RAR window; and if in a certain PDCCH After successfully decoding a downlink control information (DCI) information, the RA-RNTI corresponding to the PRACH needs to receive all RAR units in the random access response message according to the DCI information. Finally, it is possible to find the RAR unit belonging to itself according to the RAPID of the RAR unit.

However, when the maximum data packet that the PDSCH can support is small, the random access response message may not be able to accommodate all the RAR units corresponding to the above RA-RNTI. In this case, two solutions are provided in the related art:

Solution 1: Sending multiple different random access response messages by using the same RA-RNTI;

The disadvantage of this solution is that the user needs to use the same RA-RNTI to perform multiple demodulation on the PDCCH and receive multiple different random access response messages in the PDSCH. Compared with the conventional technical solution, the PDCCH needs to be in the PDCCH. Scheduling information including a plurality of random access response messages, thereby increasing the overhead of the PDCCH. And, because the user in the solution needs to receive multiple random connections In response message. Even if a random access response message does not contain the RAR unit of the user, the user must know after receiving it.

The second method reduces the number of PRACH channels or sequences corresponding to the RA-RNTI, so that the size of the maximum random access response message does not exceed the maximum data packet that the PDSCH can support.

The disadvantage of this scheme is that since the number of PRACH channels or sequences corresponding to the RA-RNTI is reduced, it effectively solves the problem that the maximum packet size that the PDSCH can support is small, but when the signal is detected, the PRACH is detected. When the number of channels or sequences is small and the distribution exceeds the narrowed PRACH channel or sequence range, the situation that was originally processed using a random access response message now needs to be processed using multiple random access response messages, which undoubtedly increases PDCCH overhead.

In summary, the above two solutions provided in the related art increase the PDCCH overhead in different situations.
