Embodiment 1

[0185] Nodes and terminals (User Equipment, UE for short) exist in the wireless system.

[0186] The node may be at least one of the following: a macro base station (Macrocell), a micro base station (Microcell), a pico base station (Picocell), a femto base station (Femtocell), a home base station, a low power node (LPN), and a relay station (Relay).

[0187] The terminal can be at least one of the following:

[0188] One or more human-to-human (HumantoHuman, H2H) communication terminals;

[0189] One or more machine-to-machine (M2M) communication terminals;

[0190] One or more device-to-device (D2D) communication terminals;

[0191] step 1:

[0192] In this embodiment, it is assumed that there are terminals UE1, UE2, UE3, UE4, UE5, and UE6. In order to access the wireless system, these UEs first send a reference signal to a node (denoted as NodeA) in the system. The reference signal is a or multiple orthogonal sequences, or one or multiple quasi-orthogonal sequences, or o...

Embodiment 2

[0223] In a wireless system there are nodes and terminals.

[0224] step 1:

[0225] In this embodiment, it is assumed that there are terminals UE1, UE2, UE3, UE4, UE5, and UE6. In order to access the wireless system, these UEs first send a reference signal to a node (denoted as NodeA) in the system. The reference signal is multiple Orthogonal sequence. The NodeA notifies the UE of the indexes that can be used as reference signals. In this embodiment, it is assumed that sequence 1 to sequence 10 are used as reference signals available to the UE.

[0226] Each of UE1~UE6 randomly selects a sequence from sequence 1~sequence 10 as a reference signal, and sends the reference signal on the time-frequency resource indicated by NodeA. The location of the time-frequency resource is as follows: Figure 11 as shown, Figure 11 is a schematic diagram of the second random access resource allocation according to an embodiment of the present invention, as shown in Figure 11 As shown, B...

Embodiment 3

[0264] In a wireless system there are nodes and terminals.

[0265] step 1:

[0266] In this embodiment, it is assumed that there are terminals UE1, UE2, UE3, UE4, UE5, and UE6. In order to access the wireless system, these UEs first send a reference signal to a node (denoted as NodeA) in the system. The reference signal is multiple Orthogonal sequence. The NodeA notifies the UE of the indexes that can be used as reference signals. In this embodiment, it is assumed that sequence 1 to sequence 10 are used as reference signals available to the UE.

[0267]Each of UE1~UE6 randomly selects multiple sequences from sequence 1~sequence 10 as reference signals, and sends reference signals on the time-frequency resources indicated by NodeA. The location of the time-frequency resources is as follows: Figure 12 as shown, Figure 12 is a schematic diagram of the third random access resource allocation according to an embodiment of the present invention, as shown in Figure 12 As show...

Abstract

The invention provides a random access configuration information sending method, receiving method, sending device and receiving device, first kind nodes and second kind nodes; the method comprises following steps: the first kind nodes receive first kind reference signals sent by the second kind nodes, wherein the second nodes comprise nodes which send the first kind reference signals belonging to a same subset of the first kind reference signals in a defined time domain resource set, wherein the first kind reference signal set comprises one or more first kind reference signal subsets, each of the first kind reference signal subsets comprise one or more first kind reference signals; the first nodes send random access configuration information to the second kind nodes according to the received first kind reference signals. By means of the methods and devices, the problem of large system resource cost by adopting correlative technical schemes for users to access the system is solved, and therefore, the resource cost is reduced.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for sending random access configuration information, a method for receiving it, a sending device, a receiving device, a first type of node, and a second type of node. Background technique [0002] In the related art, the design goal of the mobile communication system is human-to-human (Human-to-Human, H2H for short) communication. In recent years, with the vigorous development of the Internet of Things technology, machine-to-machine (M2M) user communication has also become one of the important goals in the design of future mobile communication systems. Considering the huge number of M2M users, how to ensure that a large number of M2M users can successfully access the system in the future mobile communication system is an important issue. [0003] In the mobile communication system in the related art, taking the Long Term Evolution (LTE for short) system as an example, ...
