Problems solved by technology

[0005] Embodiments of the present invention provide a method and device for determining a receiving antenna, which solves the problem that the base station or the base station controller can identify the user equipment only after waiting for subsequent downlink or uplink measurements when the user equipment transitions from the non-dedicated connection state to the connection state The problem of the uplink joint receiving antenna and the problem that the user equipment needs to send an additional channel sounding reference signal to the predetermined CoMP base station, the base station or the base station controller can determine the problem of the uplink receiving antenna, which can enhance the uplink receiving reliability of the user equipment and reduce the interference of the system

Embodiment 1

[0056] An embodiment of the present invention provides a method for determining a receiving antenna, such as figure 1 shown, including:

[0057] S101. The base station detects the signal quality of the random access preamble signal sent by the user equipment on the random access channel of the first cell received from the antenna of the second cell.

[0058] Wherein, the second cell is an adjacent cell of the first cell, and the first cell may be a cell where the user equipment in the idle state resides, or a serving cell for the user equipment in the public channel state.

[0059] When the user equipment in the idle mode selects a suitable cell to camp on, or the user equipment in the common channel state is in the serving cell, an initial random access process will be initiated. Random access is a basic function, and the user equipment can perform uplink transmission only after successfully applying for the transmission permission of the uplink random access channel through...

Embodiment 2

[0079] An embodiment of the present invention provides a method for determining a receiving antenna, such as figure 2 shown, including:

[0080] S201. The user equipment sends a preamble signal on a random access channel of the first cell.

[0081] Wherein, the first cell may be a camping cell of the user equipment in an idle state, or may be a serving cell of the user equipment in a public channel state.

[0082] When the user equipment in the idle mode selects a suitable cell to camp on, or the user equipment in the common channel state is in the serving cell, an initial random access process will be initiated. Random access is a basic function, and the user equipment can be scheduled by the system for uplink transmission only after it is synchronized with the uplink of the system through the random access process.

[0083] Random access is one of the most basic functions of the cellular system, which makes it possible for the terminal to establish a connection with the n...

Embodiment 3

[0124] An embodiment of the present invention provides a base station 1, such as image 3 shown, including:

[0125] The detection unit 10 is configured to detect the signal quality of the random access preamble signal sent by the user equipment on the random access channel of the first cell received from the antenna of the second cell, the second cell being the first cell Neighboring districts of the district;

[0126] A determining unit 11, configured to determine that the uplink receiving antenna of the user equipment includes the antenna of the second cell if the signal quality of the random access preamble signal received by the antenna of the second cell exceeds a threshold value ;

[0127] The processing unit 12 is configured to perform joint reception processing on the radio signal sent by the user equipment received by the antenna of the first cell and the radio signal sent by the user equipment received by the antenna of the second cell.

[0128] Further, as Fig...

Abstract

The invention provides a method and a device for determining reception antennas, relating to the wireless communication field. The invention enhances the reliability of the uplink reception of the user device and reduces the system interference. The method comprising: detecting signal quality of the random access preamble signal received from the antenna to the second cell of the first cell of the user equipment transmitting the random access channel, the second cell to the first cell neighboring cell; said cell if said second antenna signal to the random access preamble signal quality exceeds the threshold value, determining the uplink user equipment receiving antenna comprises an antenna of the second cell; will have said first cell of a wireless signal received by the antenna and the user equipment sends to the second cell radio signal received by the antenna of the user apparatus transmits the reception process for joint

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and device for determining a receiving antenna. Background technique [0002] The idle mode (IDLE Mode) of the user equipment is an important state of the user equipment. In the idle mode, there is no radio resource control connection (RRC, radio resource control) between the user equipment and the network, and the network does not know the cell location of the user equipment. . When the user equipment is turned on or roaming, its first task is to find and contact the network. [0003] When the user equipment accesses the system in the IDLE state, it always tries to stay in a cell where the uplink and downlink can communicate successfully. In the prior art, when the user equipment transfers from the non-dedicated connection state (idle state or public channel state) to the dedicated connection state, the base station controller or the base station needs to...
