Embodiment Construction

[0017] The technical solution of the present invention will be described in more detail below with reference to the drawings and embodiments.

[0018] A method for MIMO mode initialization provided by the present invention comprises the following steps:

[0019] a. The user sends a random access request to the base station;

[0020] b. After the base station receives the random access request, according to its state value (including any one or any combination of the following factors: the number of access users or the status of access users (such as service quality QOS) or system load, etc. ) select a multiple-input multiple-output mode for the user (for example, when the number of access users is too large, the user can be set to MU-MIMO mode, but not limited to this mode), and then add the identifier of the multiple-input multiple-output mode After entering the random access request response, send it to the user;

[0021] c. The user receives and parses out the identifier ...

Abstract

An initialization method of a multiple-input multiple-output (MIMO) mode comprises the following steps: (a) a user sends a random access request to a base station; (b) the base station selects a MIMO mode for the user according to the received random access request, adds an identification of the MIMO mode to a random access request response, and sends to the user; and (c) the user receives and resolves the identification of the MIMO mode in the random access request response. The inventive method can increase capacity and user access quantity of the system in case of large system load, so as to take equity into account, reduce cost, and better satisfy the requirements for quality of service (QoS).

Description

technical field [0001] The invention relates to a communication system supporting multiple multiple input multiple output modes, in particular to a method for initializing multiple input multiple output modes. Background technique [0002] Multiple-input multiple-output (MIMO) systems can improve system performance without increasing system bandwidth, resist multipath fading to a certain extent, and increase data rates. MIMO technology has become one of the key technologies of the next-generation wireless communication system, and the current research on MIMO systems has penetrated into various modes, such as single-user multiple-input multiple-output mode (SU-MIMO mode) and multi-user multiple-input multiple-output mode mode (MU-MIMO mode). [0003] In order to achieve the optimal performance of MIMO systems in different modes, the user feedback information (such as channel quality indicator, precoding matrix index) required for scheduling is different, so it is necessary ...
