Abstract

The invention provides a random access response method and device, a base station and a terminal. The method includes the steps that the terminal sends a random access response message, wherein the MAC PDU (media access control protocol data unit ) of the random access response message includes at least one MAC subPDU (medium access control sub-protocol data unit), and each MAC subPDU includes a MAC sub-head and a possible MAC RAR (media access control random access response) corresponding to the MAC sub-head; when there are at least two MAC subPDUs, at least two MAC sub-PDUs are sequentiallyarranged in the MAC PDU. According to the present invention, the method enables a base station gNB to quickly respond to random access requests from multiple terminals and in multiple demands, and also enables a single terminal UE to quickly receive and parse the response to the random access request sent by the terminal, thereby reducing the time delay of random access, and saving the power of the terminal.

Description

Technical field [0001] The present invention relates to the technical field of communication applications, in particular to a method, device, base station and terminal for random access response. Background technique [0002] The random access of the LTE (Long Term Evolution) system and the NR (New Radio) system is divided into two types: competitive random access and non-competitive random access. [0003] The competitive random access of the LTE system is used for: 1) initial terminal access; 2) RRC (Radio Resource Control, Radio Resource Control) connection reestablishment and handover; 3) downlink data arrival in the RRC connection state in an asynchronous state; 4) RRC Uplink data arrives in connected state; 5) Positioning in RRC connected state. The NR system also introduces system message request, inactive UE (User Equipment) to resume connection, etc. The competitive random access process such as figure 1 As shown, it is mainly divided into four steps: [0004] Msg1: The U...
