Description

Cell determination method, related equipment and system

Technical Field

The present invention relates to the field of communications, and in particular, to a method, a related device, and a system for cell determination.

Background

With the popularity of mobile devices, the network capacity pressure of operators is rising dramatically, and the shortage of spectrum resources is an increasingly severe reality. At present, 5 GigaHertz (GHz) unlicensed band has a considerable portion of available spectrum worldwide, and operators and equipment manufacturers seek to use the band to increase the carrier capacity of the Licensed band, so that Licensed-Assisted Access (LAA) technology should be developed.

In a general carrier management mode, a Primary Cell (English full name: Primary Cell, English abbreviation: PCell) issues A4 measurement configuration to User Equipment (English full name: User Equipment, English abbreviation: UE), the UE reports an A4 measurement report of a candidate frequency point to a base station, and the base station selects a candidate Cell according to the A4 measurement report. However, the UE measurement capability is limited, and a single UE supports measurement of at most 16 frequency points, and since the number of frequency points that may be used is greater than the measurement capability of the UE, when the measurement is configured for the secondary carrier, how to obtain a suitable cell by the UE becomes a problem.

The scheme adopted at present is that a base station selects part of frequency points from all candidate frequency points to measure UE, and sets a timer, if the UE does not measure a proper LAA cell before the timer is overtime, the base station stops the original measurement, and issues a new measurement control signaling again.

However, in practical situations, the UE may not be able to measure a suitable LAA cell within a certain time, which requires the base station to issue new measurement control signaling to the UE multiple times, resulting in more air interface signaling.

Disclosure of Invention

The terms "first," "second," "third," "fourth," and the like in the description and in the claims, as well as in the drawings, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

It should be understood that the technical solutions of the embodiments of the present invention can be applied to various communication systems, for example: global System for Mobile communications (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), General Packet Radio Service (GPRS), a Long Term Evolution (Long Term Evolution, abbreviated in english) System, an LTE Frequency Division Duplex (FDD) System, an LTE Time Division Duplex (TDD), a Universal Mobile Telecommunications System (UMTS), or a Worldwide Interoperability for microwave Access (WiMAX) communication System, etc.

For example, the LTE network technology can be used in an unlicensed frequency band, based on a carrier aggregation architecture, a licensed frequency band carrier is used as a PCell, and an unlicensed frequency band carrier can only be used as a Secondary cell (SCell). Meanwhile, in order to ensure the coexistence with other technologies working in the unlicensed frequency band, a channel contention access mechanism of Listen Before Talk (English full name: Listen-Before-Talk, English abbreviation: LBT) is adopted.

The PCell is a cell operating in a primary frequency band, where the UE performs an initial connection establishment procedure or starts a connection re-establishment procedure, and the cell is indicated as a primary cell in a handover procedure. An SCell is a cell operating on a secondary band, and may be configured to provide additional radio resources once an RRC connection is established. In the LTE system, after entering a connected state, the UE may communicate with a source base station through multiple Component carriers at the same time, and the base station may assign a Primary Component Carrier (PCC) to the UE through explicit configuration or according to protocol agreement, where the other Component carriers are called Secondary Component Carriers (SCC), a serving cell on the PCC is called a Pcell, and a serving cell on the SCC is called a Scell.

For the downlink direction, the optical fiber is directly connected to the RRU from the BBU, and baseband digital signals are transmitted between the BBU and the RRU, so that a base station can control signals of a certain user to be transmitted from a specified RRU channel, and the interference to the users on other channels of the cell can be greatly reduced. For the uplink direction, the mobile phone signals of the users are received by the channel with the closest distance and then transmitted to the base station from the channel through the optical fiber, so that the interference among the users on different channels can be greatly reduced.

An antenna is a transducer that converts a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium, or vice versa. A component for transmitting or receiving electromagnetic waves in a radio device. Engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasure, remote sensing and radio astronomy, all of which use electromagnetic waves to transmit information, rely on antennas to operate. In addition, in transferring energy with electromagnetic waves, non-signal energy radiation also requires antennas. The antennas are generally reciprocal in that the same pair of antennas can be used as both transmit and receive antennas.

The touch panel 531, also called a touch screen, can collect touch operations of a user on or near the touch panel 531 (for example, operations of the user on or near the touch panel 531 by using any suitable object or accessory such as a finger or a stylus pen), and drive the corresponding connection device according to a preset program. Alternatively, the touch panel 531 may include two parts, a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, and sends the touch point coordinates to the processor 580, and can receive and execute commands sent by the processor 580.

WiFi belongs to short distance wireless transmission technology, and the mobile phone can help the user to send and receive e-mail, browse web pages, access streaming media, etc. through the WiFi module 570, which provides wireless broadband internet access for the user. Although fig. 14 shows the WiFi module 570, it is understood that it does not belong to the essential constitution of the handset, and may be omitted entirely as needed within the scope not changing the essence of the invention.
