Problems solved by technology

[0006] Disadvantage: Requires a lot of radio bandwidth resources
[0010] Cons: COPEX is the highest of the three solutions
[0014] Disadvantages: relatively high COPEX
[0021] - Low power efficiency when the macro BS is kept in a low transmit power state (e.g. midnight, there is a low load)

example 1

[0046] Figure 4 A flow chart of a method performed at a base station according to an embodiment of the present disclosure is shown.

[0047] like Figure 4 As shown, the method starts at step S410, and the method includes that the base station uses one or more carriers (hereinafter referred to as "first carrier") to serve an area (hereinafter referred to as "cell"). If a hotspot is detected in the cell, at step S420, the method further includes using one or more carriers (hereinafter referred to as "second carriers") to serve the hotspot. The first and second carriers share the total transmit power used to serve the area or cell.

[0048] A "hot spot" as used herein refers to a geographical area in a cell where traffic is highly concentrated. UEs in a hotspot can move around. Therefore, a hotspot has two properties, direction and mobility. In an embodiment, beamforming techniques are applied to serve hotspots. Beamforming techniques are able to cover both properties and...

[0063] Image 6 is a flowchart of a method executed at a base station according to another embodiment of the present disclosure.

[0064] like Image 6 As shown, the method starts, and at step S610, the base station uses one or more first carriers to serve the cell. At step S620, it is detected whether a hot spot appears or exists.

[0065] It should be noted that traffic intensity varies with time and location. For example, for a community with two office buildings and one residential area, two hot spots appear in the office building from 9:00 am to 5:00 pm, and one hot spot appears in the residential area from 5:00 pm to 9:00 am . Thus, the operator may store a list of hotspots indicating the time and location of the hotspots in the cell. The base station can look up the list to see if a hotspot exists.

[0066] If the hotspot exists, the method further includes that in step S630, the base station selects a carrier to serve the hotspot. For example, one of the 10MHz c...

Abstract

There is provided a base station (BS) (1000) and a method at the BS that is capable of enhancing network capacity with low transmission power in a radio network. The method comprises serving a cell with one or more first carriers. The method further comprises serving a hot-spot within the cell with one or more beam-formed second carriers, wherein the first and second carriers share a total transmission power for serving the cell. Beam-forming based hot-spot carriers can efficiently save transmission power and contribute to the total power utilization efficiency. The base station (1000) thus can meet the capacity enhancement requirement with low transmission power.

Description

technical field [0001] The present disclosure relates to the field of radio networks, and more particularly, to a base station (BS) capable of increasing network capacity with low transmission power in a radio network and a method thereof. Background technique [0002] For operators, one step in deploying radio networks is to build macro BSs to guarantee basic coverage. There are usually no high capacity requirements during the initial deployment phase. However, as the network develops, the network will serve more and more user equipments (UEs). Some BSs will require capacity expansion. In general, there are three main solutions as listed below to improve macro deployment with capture capacity requirements. figure 1 A schematic diagram of three solutions is shown. [0003] ●Improve macros [0004] Macrocapacity is improved by eg adding more carriers. This approach is usually the cheapest solution for those operators with sufficient radio bandwidth resources, since ther...
