[0008] Case 3: The UE needs to measure the gap to measure the frequency point, which will affect the data transmission and reception of the UE at the working frequency point, and the data transmission and reception of the working frequency point cannot be performed during the gap measurement period
[0009] Since the UE capability currently only includes the information of measuring the gap, but does not include the information of the number of receivers, the network cannot distinguish between case 1 and case 2, and thus cannot achieve the goal of saving UE power through reasonable measurement configuration.
For example, the UE has two receivers. The currently working receiver 1 needs a gap to measure a certain frequency point, while the closed receiver 2 does not need a gap to measure this frequency point. Therefore, the UE's measurement capability will instruct the UE to measure this frequency point. The point does not need a gap. At this time, the network side may think that the UE’s measurement of this frequency point belongs to the case 1, so the gap is not configured. In this way, the UE must turn on the receiver 2 to measure, and the purpose of saving power cannot be achieved.

Embodiment 1

[0061] Embodiment 1: Radio frequency capability extension

[0062] Assume that the UE currently has 4 receivers, where receivers 1 and 2 have the same radio frequency capabilities (support the same band and duplex mode), and receivers 3 and 4 have the same radio frequency capabilities, as shown in the following table:

[0063] receiver

RF capability (take the supported band as an example)

1

Support band1, band2, band3, band4

2

Support band1, band2, band3, band4

3

Support band3, band4, band5, band6

4

Support band3, band4, band5, band6

[0064] In order to reflect the receiver capability of the UE, the type (or number) of receivers supporting a certain band is extended in the radio frequency capability:

[0065] Bands supported by UE

The type (or number) of receivers that support the band

band2

band3

Embodiment 2

[0068] Example 2: Measurement Capability Expansion

[0069] UE capabilities are the same as those in Embodiment 1. In order to reflect the receiver capability of the UE, expand the reason why gaps are not required for measuring other bands under a certain band in the measurement capability (whether it is multiple receivers):

[0070] working band

[0071] The "reason for not needing gap" information in the above table is information that allows the network to know the capability of the UE receiver. If you want to add this content, you need to extend the current UE capability information, such as RRC messages. The extension method can be to add an IE (information element) under the measurement capability of each band to another band, which means "no Reason for needing gap", for example, add 1 bit, if gap is needed, this bit will not appear, if gap is not needed, and the reason is "single receiver, adjustable center frequency", this bit will be set to "0", If the gap...

Embodiment 3

[0074] Embodiment 3: Combined use of radio frequency capability expansion and measurement capability expansion

[0075] UE capabilities are the same as those in Embodiment 1. In order to reflect the receiver capability of the UE, the radio frequency capability extension and the measurement capability extension can be used in combination. For example, extending the radio frequency capability by 1 bit indicates whether a certain band is one type (one) or multiple types (multiple) of receivers, as described in Embodiment 1, and simultaneously extending the measurement capability by 1 bit, indicating that no gap is required, yes Because of "single receiver, adjustable center frequency" or "multiple receivers". After obtaining the capability of the UE, the base station may combine the two to determine the receiver capability of the UE. The manner in which the base station acquires UE capabilities is the same as that described in Embodiment 1.

Abstract

The embodiment of the invention provides a receiving capability reporting method, which comprises the following steps that: user equipment (UE) sends information to a base station, and the information includes UE receiving machine capability information; the UE receives measuring configuration information sent by the base station, and according to the measuring configuration information, the UE saves electricity or does not interrupt data transmission when the UE carries out other non-work frequency point measurement. On the other hand, the embodiment of the invention also provides the UE, which comprises a sending module, a measuring module and a receiving module. Through the technical scheme provided by the invention, the radio frequency capability and the measuring capability of a UE reporting receiving machine are optimized, and a network side base station takes receiving machine capability as the reference for carrying out measuring configuration on the UE after obtaining the UE receiving machine capability, so when the UE carries out other non-work-frequency-point measurement, the electricity is saved, or the data transmission is not interrupted.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular, the present invention relates to a method and equipment for receiving capability report. Background technique [0002] Mobile and broadband have become the development direction of modern communication technology. 3GPP (3rd Generation Partnership Project) is committed to the evolution of LTE (Long Term Evolution, long-term evolution) system as a 3G system. The goal is to develop 3GPP wireless access technology towards Evolution for high data rate, low latency and optimized packet data applications. In future mobile communication systems, such as B3G: Beyond three Generation or LTE-A (Long Term Evolution Advanced, Long Term Evolution Advanced), the system will provide higher peak data rate and cell data throughput, so the system A wider transmission bandwidth is also required. [0003] In LTE and previous wireless communication systems, there is only one carrier in a ce...
