Technical field

The present disclosure relates to the field of communication technology, and in particular to a method for sending a message, a method for receiving a message, a terminal device and a network device.

Background technique

Fifth Generation (5 ^th Generation, 5G) mobile communication system, or as a new air interface (New Radio, NR) system needs to adapt to a variety of scenes and business needs, the system includes a main scene NR Enhanced Mobile Broadband (enhanced Mobile Broadband , EMBB) communications, large-scale Internet of Things (massive Machine Type Communications, mMTC) communications and ultra-reliable and low-latency communications (Ultra-Reliable and Low Latency Communications, URLLC). These scenarios put forward requirements for the system such as high reliability, low latency, large bandwidth and wide coverage. For services that occur periodically and have small and large data packets, in order to reduce the overhead of downlink control signaling, network equipment can adopt a semi-static scheduling method to continuously allocate certain resources for transmission of periodic services.

In the uplink transmission mode, if the terminal needs to send uplink data, it must first obtain the uplink timing synchronization through the random access process, that is, obtain the uplink timing advance (TA) information from the network device. After the uplink synchronization is obtained, the terminal can pass Dynamic scheduling or semi-persistent scheduling to send uplink data. When the uplink data packet is small, in order to reduce the consumption of resources and power, the terminal can send uplink data in an asynchronous state.

In the random access process, such as the non-competitive random access process or the competitive random access process, the terminal is also in an asynchronous state when sending the preamble, and a cyclic prefix (CP) needs to be added to the preamble. To offset the impact of transmission delay, there is a guard interval (Guard) between different terminals to reduce interference.

When a terminal device such as a user equipment (User Equipment, UE) initiates a 2-step random access procedure, it can send a random access message msgA on the corresponding Physical Uplink Shared Channel (PUSCH). When the UE sends msgA on the PUSCH, it needs to select an appropriate beam to send. However, since the network device cannot know the beam direction when the UE sends msgA on the PUSCH, the network device needs to detect all possible beam directions when receiving the msgA, resulting in long processing time and high power consumption.

Summary of the invention

detailed description

First of all, it should be pointed out that some embodiments of the present disclosure can be applied to a 2-step random access process or a 4-step random access process. The random access message involved can be that the terminal device initiates a 2-step random access process. It may be sent when the 4-step random access process is initiated, and some embodiments of the present disclosure do not limit this.

Please refer to FIG. 1. FIG. 1 is a flowchart of a message sending method provided by some embodiments of the present disclosure. The method is applied to a terminal device. As shown in FIG. 1, the method includes the following steps:

Step 101: Obtain the mapping relationship between downlink reference signals and PUSCH resources.

In this embodiment, the mapping relationship between the downlink reference signal and the PUSCH resource may be configured by the network, or may be predefined. For example, the protocol stipulates that the downlink reference signal and the PUSCH resource are separately numbered, and the association relationship between the downlink reference signal and the PUSCH resource number is given. The downlink reference signal may be configured by the network device or sent by the network device. The downlink reference signal may include at least one of the following:

Synchronization signal physical broadcast channel block (Synchronization Signal and Physical Broadcast Channel Block, SSB), channel state information reference signal (Channel State Information Reference Signal, CSI-RS), etc.

The PUSCH resource may include at least one of the following: time domain resources, frequency domain resources, demodulation reference signal (Dedicated Reference Signal, DMRS) parameters, PUSCH scrambling parameters, and so on.

Further, the DMRS parameters may include at least one of the following: DMRS ports, DMRS scrambling parameters, DMRS scrambling identifiers, DMRS sequence hopping parameters, and so on.

Step 102: Send a random access message according to the mapping relationship.

Wherein, when the terminal device sends the random access message according to the mapping relationship, it may first determine the PUSCH resource for sending the random access message according to the mapping relationship, and the PUSCH resource corresponds to a downlink reference signal meeting a preset condition. Then, based on the determined PUSCH resource, a random access resource is selected and a random access message is sent on the random access resource.

In an implementation manner, the terminal device sends a random access message on the random access resource according to the mapping relationship. Among them, random access resources are used for random access procedures, and random access resources include PUSCH resources. Specifically, the terminal may select the PUSCH resource corresponding to the downlink reference signal as the random access resource, and send the random access message.

It should be noted that when selecting a random access resource based on the determined PUSCH resource in this embodiment, if the PUSCH resource is a PUSCH resource, the PUSCH resource can be directly used as a random access resource, and if the PUSCH resource is more For each PUSCH resource, one PUSCH resource can be selected as a random access resource from multiple PUSCH resources according to preset conditions.

In the message sending method of some embodiments of the present disclosure, the mapping relationship between the downlink reference signal and the PUSCH resource is acquired, and the random access message is sent according to the mapping relationship. In this way, according to the mapping relationship between the downlink reference signal and the PUSCH resource, the beam direction corresponding to the PUSCH sending the random access message can be determined, and the beam direction is the beam direction of the downlink reference signal corresponding to the PUSCH resource sending the random access message. Therefore, when the network device receives the random access message, it can perform detection in a limited or fewer beam directions, thereby reducing its processing time and power consumption, and improving reception performance.

In some embodiments of the present disclosure, optionally, when the PUSCH resources include time-frequency domain resources, the time-frequency domain resources of at least two PUSCH resources do not overlap at least in part.
