Embodiment 1

[0086] The UE is in the connected state in the EUTRAN system, and the UE has two separate receivers, each supporting a bandwidth of 20M, such as image 3 As shown, receiver 1 supports working on frequency bands 1, 2 and 3, and receiver 2 supports working on frequency bands 1, 4 and 5.

[0087] Frequency band refers to the number of a certain uplink and downlink frequency band, as mentioned in Table 5.5-1 in 36.101 (Evolved Universal Terrestrial Radio Access (E-UTRA); User Equipment (UE) radio transmission and reception), frequency band 1 It represents the frequency band of uplink 1920MHz to 1980MHz and downlink 2110MHz to 2170MHz in FDD (Frequency Division Duplexing).

[0088] The currently defined intra-system measurement events supported by LTE-A are:

[0089] Event A1: The signal quality of the serving cell is higher than a specified threshold.

[0090] Event A2: The signal quality of the serving cell is lower than a specified threshold.

[0091] Event A3: The signal qua...

Embodiment 2

[0115] The UE is in the connected state in the EUTRAN system, and the UE has three separate receivers, each supporting a bandwidth of 20M, such as Figure 5 shown.

[0116] Figure 6 As shown, the process of this embodiment includes the following steps:

[0117] Step 201, the UE configures cell1 with the center frequency on F1 and cell2 with the center frequency on F2 during the communication process. Both F1 and F2 belong to frequency band 1. The UE allocates resources according to its own situation. As a result, the current UE receives The use of the machine is: receiver 1 works on cell1, receiver 2 works on cell2, and the following measurement tasks are configured at the same time, where F3 belongs to frequency band 5:

[0118] MID=1, MO=F1, RC=A3

[0119] MID=2, MO=F2, RC=A6

[0120] MID=3, MO=F3, RC=A3

[0121] Step 202, the base station discovers that the configured measurement task includes inter-frequency measurement (MID=3), then decides to configure the measurem...

Embodiment 3

[0136] The UE is in the connected state in the EUTRAN system, and the UE has a separate receiver that supports a bandwidth of 40M, such as Figure 7 shown.

[0137] Figure 8 As shown, the process of this embodiment includes the following steps:

[0138] Step 301. During the communication process, the UE configures cell1 with a center frequency on F1 and cell2 with a center frequency on F2. Both belong to frequency band 1 and are continuous. The UE allocates resources according to its own conditions. As a result, the current UE The use of the receiver is: receiver 1 works on cell1 and cell2 at the same time, and the following measurement tasks are configured at the same time:

[0139] MID=1, MO=F1, RC=A3;

[0140] MID=2, MO=F2, RC=A6;

[0141] MID=3, MO=F3, RC=A3;

[0142] MID=4, MO=F4, RC=B2.

[0143] Among them, F3 belongs to frequency band 2, and F4 belongs to frequency band 3.

[0144] Step 302, the base station discovers that the configured measurement tasks includ...

Abstract

The invention provides a method for configuring a measurement interval in carrier aggregation, UE (User Equipment) and a base station. The method comprises the following steps that: after receiving a wireless parameter configuration message sent by the base station, the UE configures the measurement interval or does not configure the measurement interval according to measurement interval configuration auxiliary information determined by the UE, and feedbacks the measurement interval configuration auxiliary information to the base station. The UE comprises a configuration module and a sending module; and the base station comprises a determining module. According to the invention, the configuration of the measurement interval in the carrier aggregation can be realized, the UE does not need to report the internal structure, the measurement interval is configured as required, the influence of the measurement interval on service can be reduced, and the data transmission quality and the system capacity are improved.

Description

technical field [0001] The invention relates to the technical field of digital mobile communication, and mainly relates to a method for configuring measurement intervals in carrier aggregation, user equipment and a base station. Background technique [0002] In cellular mobile communication systems, cell reselection and handover are important functions. In order to realize cell reselection smoothly, user equipment (User Equipment, UE for short) needs to measure the signal quality of different cells, so as to select a suitable cell to camp on. After the UE establishes a connection with the network in a certain cell, the UE still needs to measure the signal quality of its neighboring cells in order to select a suitable cell for handover and meet mobility requirements. [0003] When the terminal is in the connected state, the specific process of measurement is: the network side sends a measurement control message to the UE, wherein the measurement control message includes a me...
