Problems solved by technology

[0007] Although in 5G, a duplication mechanism is introduced for PDSCH and PUSCH, for the RACH process in the unconnected state, since the UE is not connected to the network side, the duplication of uplink information and downlink information in the RACH process cannot be clarified between the UE and the network side frequency
In the prior art, how to determine the number of repetitions of uplink and downlink information in the RACH process has not been disclosed

Embodiment Construction

[0041] In order to explain the technical solutions of the embodiments of the present invention more clearly, the following will briefly introduce the drawings needed in the embodiments of the present invention. Obviously, the drawings in the following description are only some embodiments of the present invention. A person of ordinary skill in the art can obtain other drawings based on these drawings without creative labor.

[0042] See figure 1 As shown, the embodiment of the present invention provides a method for sending and receiving information, which is applied to a terminal device and includes the following steps:

[0043] Step 101: Determine the number of repetitions of the uplink channel or the uplink and downlink channels of the terminal equipment in the RACH process.

[0044] It should be noted that the uplink channel of the terminal device may be PUSCH (Physical Uplink Shared Channel, physical uplink shared channel), PUCCH (Physical Uplink Control Channel, physical uplink...

Abstract

The invention provides an information transmitting and receiving method, terminal equipment and network equipment. The method for transmitting and receiving the information comprises the following steps: determining the repetition frequency of an uplink channel or an uplink and downlink channel of terminal equipment in a random access process, and transmitting the uplink information or transmitting the uplink information and receiving the downlink information by adopting the repetition frequency in the random access process. According to the scheme of the invention, how to determine the repetition frequency of uplink and downlink information in the random access process can be clearly determined.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to a method, terminal equipment and network equipment for sending and receiving information. Background technique [0002] In the future 5G (5Generation, fifth generation) mobile communication system, in order to improve the transmission reliability of the uplink and downlink, PDSCH (Physical Downlink Shared Channel, physical downlink shared channel) and PUSCH (Physical Uplink Shared Channel, physical uplink shared channel) A repetition mechanism is introduced, that is, the data block corresponding to each PDSCH or PUSCH is repeatedly sent, and the number of repetitions can be 1, 2, 4, or 8. On the terminal side, the received repeated data is combined and demodulated to improve transmission reliability. [0003] In the 5G system, in order to reduce signaling overhead, improve radio resource utilization, and reduce base station energy consumption, NR (New Radio) proposes...
