specific Embodiment 1

[0065] The implementation scenario of this preferred embodiment is that the UE is located at the edge of a cell in an N-frequency network, and there are two cells, CELL 1 and CELL 2, within the receiving range of the UE.

[0066] The overall process of this embodiment is attached figure 1 Shown:

[0067] 1. The UE sets at least two directional transceiving channels covering different spatial ranges, and the directional transceiving channels together cover the omnidirectional transceiving spatial range of the mobile device;

[0068] In this embodiment, the number of directional transceiver channels is 3, corresponding to the channel numbers 1, 2, and 3, and the space ratios occupied in omnidirectional coverage are 1 / 2, 1 / 4, and 1 / 4 respectively;

[0069] 2. The mobile device performs cell search based on all directional transceiver channels, and selects a serving cell to reside in;

[0070] This step further includes:

[0071] 201. Each directional channel receives the signa...

specific Embodiment 2

[0131] The implementation scenario of this preferred embodiment is that the UE is in the BBU+RRU high-speed railway coverage scenario (train moving speed 450km / h), and the two RRUs of the BBU belonging to the same cell CELL 1 cover the edge overlapping area.

[0132] The overall process of this embodiment is attached figure 1 Shown:

[0133] Steps 1~2 are identical with specific embodiment 1;

[0134] In this embodiment, the number of directional transceiver channels is set to 2, and the corresponding channel numbers are 1, 2, and the space ratios occupied in the omnidirectional coverage are 1 / 2, 1 / 2 respectively;

[0135] In this embodiment, after step 2, select CELL 1 to reside in as the serving cell;

[0136] 3. Taking the preset channel selection time as the cycle, each directional transceiver channel independently measures and monitors the signal quality of the candidate cells in the list of all neighboring cells; selects at least one directional transceiver channel wit...

specific Embodiment 3

[0163] The implementation scenario of this preferred embodiment is that the UE is in a BBU+RRU high-speed railway coverage scenario (train moving speed 450km / h), and two RRUs of BBUs belonging to two different cells CELL 1 and CELL 2 respectively belong to two different cells. overlapping area.

[0164] The overall process of this embodiment is attached figure 1 Shown:

[0165] Steps 1 and 2 are identical to the specific embodiment 2;

[0166] Wherein, after step 2, CELL 1 is selected as the serving cell to reside in;

[0167] 3. Taking the preset channel selection time as the cycle, each directional transceiver channel independently measures and monitors the signal quality of the candidate cells in the list of all neighboring cells; selects at least one directional transceiver channel with the best signal quality for receiving the serving cell as the active channel, based on Activate the channel to send and receive signals; the specific process of this step is attached F...

Abstract

The invention discloses a method for receiving and sending mobile equipment signals. At least two directed receiving and sending channels covering different space ranges are arranged in mobile equipment; the directed receiving and sending channels are combined to jointly cover the omnibearing receiving and sending range of the mobile equipment; on the basis of the directed receiving and sending channels, cell search and serving cell selection are carried out by the mobile equipment to select one serving cell for residence; each directed receiving and sending channel independently monitors the quality of signals of all cells by taking preset channel selection time as a period; at least one directed receiving and sending channel with the best quality of the signal of the serving cell is selected to serve as an activated channel; and the signal is received and sent on the basis of the activated channel. In the method disclosed by the invention, same-frequency interference radiation intensity and a Doppler frequency shift hopping range are successfully lowered by spatial subdivision, the severe technical difficulties of same-frequency interference, resonance offset of high-speed rail scene signals, dramatic hopping for Doppler frequency shift and the like of the mobile equipment side in a commercial network are effectively solved, and the performance representation of the mobile equipment is obviously improved.

Description

technical field [0001] The invention relates to a method for transmitting and receiving signals of mobile equipment in a mobile communication system, in particular to a method for transmitting and receiving signals of mobile equipment in a time division synchronization-code division multiple access system. Background technique [0002] With the continuous deepening of time division-synchronous code division multiple access (abbreviation, TD-SCDMA) system evolution process, such as N-frequency point networking, high-speed packet access (abbreviation, HSPA), multimedia broadcast multicast (abbreviation, MBMS), Technologies such as high-speed rail (referred to as HST) coverage have been promoted and applied successively, effectively improving the market performance of TD-SCDMA system. [0003] However, the N-frequency point networking technology inevitably introduces more prominent co-channel interference components while improving the system spectrum utilization rate, which im...
