specific Embodiment 1

[0062] In this embodiment, frequency resources are divided into four FPs. where [FP 1 , FP 2 , FP 3 ] The frequency reuse factor is Reuse1 / 3, FP 4 The frequency reuse factor of is Reuse1, such as image 3 shown. Sector One [FP 1 , FP 2 , FP 3 , FP 4 ] The transmit power is [P High , P Low1 , P Low2 , P reuse1 ], sector two in [FP 1 , FP 2 , FP 3 , FP 4 ] The transmit power is [P Low2 , P High , P Low1 , P reuse1 ], sector three in [FP 1 , FP 2 , FP 3 , FP 4 ] The transmit power is [P Low1 , P Low2 , P High , P reuse1 ], and satisfy the condition P High >P reuse1 >=P Low1 >=P Low2 . The above basic configuration information is notified by the upper layer network element to the corresponding base station through the air interface and / or backbone network (Backbone, Backhaul), and then the base station sends the above basic configuration information to the terminal through corresponding signaling. Wherein, the upper-layer network element refers to ...

specific Embodiment 2

[0070] The schematic diagram of the frequency resource allocation method and the transmission power of each subband in this embodiment continues as follows image 3 shown. Specifically, the RM selection rule of FP in this embodiment is: select the k with the lowest transmission power in the FP set whose frequency reuse factor is Reuse q (q is not equal to 1). n - RM of 1 FP where k n is the number of FPs in the FP set whose frequency reuse factor is Reuse q (q is not equal to 1).

[0071] The sum value a of the RM of each FP in the FP set of Reuse1 / 3 (a=3 in this embodiment) and the Resource Metric of the FP of Reuse1 is b (b=1 in this embodiment) is determined by the upper network element and notified to The base station, and then the base station sends it to the terminal through corresponding signaling; or stores it in the base station and the terminal as a default configuration.

[0072] The following uses sector 1 as an example to describe in detail the method for sendi...

specific Embodiment 3

[0079] by Figure 4 As an example to describe this embodiment in detail, such as Figure 4 As shown, this embodiment divides frequency resources into four FPs. where [FP 1 , FP 2 , FP 3 ] The frequency reuse factor is Reuse1 / 3, FP 4 The frequency reuse factor of is Reuse1. Sector One [FP 1 , FP 2 , FP 3 , FP 4 ] The transmit power is [P High , P Low , P Low , P reuse1 ], sector two in [FP 1 , FP 2 , FP 3 , FP 4 ] The transmit power is [P Low , P High , P Low , P reuse1 ], sector three in [FP 1 , FP 2 , FP 3 , FP 4 ] The transmit power is [P Low , P Low , P High , P reuse1 ], and satisfy the condition P High >=P reuse1 >P Low . The above basic configuration information is notified by the upper layer network element to the corresponding base station through the air interface and / or the backbone network, and then the base station sends the above basic configuration information to the terminal through corresponding signaling.

[0080] The upper net...

Abstract

Reception and transmission methods for resource metric value are disclosed in the present invention. The transmission method includes: a base station selects the resource metric value of a corresponding frequency partition in a frequency partition set according to a selection rule (S201), and transmits the resource metric value selected to a terminal through a downlink channel in a determined time period (S202); the reception method includes: a terminal receives and decodes the resource metric value transmitted by the base station in the determined time period, and recovers the resource metric values of all unknown frequency partitions based on the resource metric value decoded. A base station and a terminal are also disclosed in the present invention. Reception and transmission methods for resource metric value provided in the present invention realizes that the base station transmits the resource metric value of part of frequency partition to the terminal every time, the terminal recovers the resource metric values of all frequency partitions using decoding algorithm. The present invention greatly reduces the overhead of system compared with the prior art.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for sending and receiving resource measurement values. Background technique [0002] In a wireless communication system, a base station refers to the equipment that provides services for the terminal. The base station communicates with the terminal through the up / down link. Downlink or forward refers to the direction from the base station to the terminal, and uplink or reverse refers to the direction from the terminal to the base station. direction. Multiple terminals can simultaneously send data to the base station through the uplink, and can also receive data from the base station through the downlink at the same time. [0003] In a data transmission system that adopts base station scheduling control, the scheduling and allocation of all system resources is usually performed by the base station. Scheduling assignments. [0004] In a...
