Problems solved by technology

[0007] The present invention provides a measurement quantity processing method and device to at least solve the problem in the related art that in the unlicensed carrier, when the base station schedules the UE to send uplink, there will be adjacent stations sending downlink data, which will cause the UE to fail to perform CCA detection.

Embodiment 1

[0072] Mainly describe the position (or quantity) of the downlink subframe and / or the position (or quantity) of the uplink subframe occupied by the adjacent base station received by the UE feedback.

[0073]The base station configures the UE to perform periodic or aperiodic unlicensed carrier usage measurement of neighboring sites through signaling, and report the results, or the UE measurement is determined independently, and the base station only triggers periodic or aperiodic reporting results. It may also be a manner agreed between the base station and the UE, without sending signaling. If signaling is sent, DCI signaling can be used to carry the signaling. For example, the existing UL index bits in DCI are used to represent the above configuration signaling. Let the meaning be resolved, and then the UE reports the usage measurement result or performs the usage measurement. If no signaling is sent, when the UE is in the RRC connected state, it can periodically report the ...

Embodiment 2

[0076] On the basis of Embodiment 1, the content reported by the UE is modified so that the UE reports the expected subframe positions (may be multiple) for sending uplink data.

[0077] The base station configures the UE to perform periodic or aperiodic reporting of the position information of the subframe where the UE expects to send uplink data through signaling. Here, the UE measurement means that the UE performs usage measurement autonomously, or starts to perform usage measurement after receiving the above signaling. The UE needs to calculate the subframe position where it expects to send uplink data from the usage measurement result, and form a report message to send to The base station, the base station schedules the UE to send uplink data in a desired uplink subframe (the UE may also obtain the desired subframe position for sending uplink data in other ways). It may also be a manner agreed between the base station and the UE, and it is no longer necessary to send the ...

Embodiment 3

[0084] It mainly describes the subframe positions (may be multiple) where the UE feeds back expected uplink grant information.

[0085] The difference between Embodiment 3 and Embodiment 2 is that there is a fixed relationship between the subframe position where the UE expects to receive uplink grant information fed back in Embodiment 3 and the subframe position where the UE expects to send uplink data that is fed back in Embodiment 2. conversion relationship. For example, for FDD, the subframe position + 4 for receiving the uplink grant information is the subframe in which the UE sends the uplink data scheduled this time. In the TDD system, a fixed conversion relationship also exists, but the fixed value may be different for each subframe, but it is still a fixed value. Therefore, in Embodiment 3, it is only necessary to convert and process the feedback information in Embodiment 2, and to modify correspondingly the meaning of the signaling. The principles are the same and w...

Abstract

The present invention provides a measurement quantity processing method and device, including: the network side receives the position and quantity of the downlink and / or uplink subframe reported by the user equipment UE, wherein the position and quantity of the downlink and / or uplink subframe are The situation of UE’s neighboring stations occupying unlicensed carriers; the network side configures the subframe position for scheduling UE according to the position and quantity of downlink and / or uplink subframes; or the expected scheduled time obtained by calculating the position and quantity of uplink subframes, wherein the expected scheduled time of the UE includes: the subframe position expected by the UE to send uplink data, and / or the subframe for receiving uplink grant information frame position. The invention solves the problem in the related art that in the unlicensed carrier, when the base station schedules the UE to send uplink, there will be adjacent stations sending downlink data, which will cause the UE to fail to perform CCA detection.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for processing measurement quantities. Background technique [0002] At present, long-term evolution technology (LTE for short) communication networks are deployed and operated on licensed carriers. With the development of LTE, some companies have proposed "suggesting research on the topic of LTE deployment on unlicensed carriers." For example, Qualcomm in the United States believes that: with the rapid growth of data services, authorized carriers will not be able to withstand the huge amount of data brought by rapid service growth in the near future. Consider deploying LTE in unlicensed carriers to share the data traffic in licensed carriers, which can solve the pressure on data volume brought about by business growth. At the same time, unlicensed carriers have the following characteristics: on the one hand, because unlicensed carriers do not need to be pu...
