Embodiment 1

[0038] This embodiment provides a method for configuring uplink resources. This embodiment combines the above embodiments and preferred implementation modes therein. The method includes:

[0039] Step 1: According to the signal-to-interference and noise ratio SINR reported by the terminal, the number of resource blocks pre-allocated for the terminal's bearer service, and the latest reported PHR value and the corresponding number of RBs, determine whether there is resource limitation, whether it is limited, and the subsequent processing methods are different

[0040] Step 2: Calculate whether the current power is limited or not according to the available RB resources, and process according to the pre-allocated configuration. Special handling for restricted UEs.

[0041] Step 3: Taking the reported SINR into consideration of the effects of Adaptive Modulation and Coding (AMC) and the maximum transmission power, performing single RB conversion processing to obtain SingleRB_SINR. ...

Embodiment 2

[0046] This embodiment provides a method for configuring uplink resources. This embodiment combines the above-mentioned embodiments and preferred implementation manners. figure 2 is a flowchart of an uplink resource scheduling method combined with power information according to an embodiment of the present invention, as shown in figure 2 As shown, in this implementation, taking broadband RB allocation as an example (the process of offspring scheduling is similar to broadband) the method includes:

[0047] Step S202: According to the previously allocated RB number M1 and the RB allocation bitmap, allocate RBs starting from the smallest number. If there are M1 consecutive RBs allocated to the UE, then go to step S206; otherwise, go to step S218. TBsize, denoted as TBsize_in.

[0048] Step S204: Calculate the corresponding PHR according to the estimated number of RBs M1, if the power of the UE is limited, that is, the PHR is less than 0, go to step S206, otherwise go to step S...

Abstract

The invention provides a method and a device for upstream resource allocation. The method comprises the following steps of: determining a terminal is in a power limited state by a base station, wherein the power limited state means that an expected transmitting power of the terminal is beyond a maximum transmitting power of the terminal, and the condition of a scheduled BLER (Block Error Ratio) is met by the expected transmitting power; determining a SingleRB_SINR (Single Resource Block_Signal Interference Noise Ratio) by the base station by using an SINR and a PHR (Power Headroom Report) reported by the terminal; and determining the upstream resource allocation by the base station by using the SingleRB_SINR. According to the method and the device for the upstream resource allocation, provided by the invention, the utilization rate of an upstream resource is increased.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for configuring uplink resources. Background technique [0002] With the development of wireless communication technology, new technologies such as Orthogonal Frequency Division Multiplexing (OFDM) are applied in wireless broadband access systems (such as Worldwide Interoperability for Microwave Access (Worldwide Interoperability for Microwave Access, referred to as In WiMAX), the access speed of wireless communication is increased to the order of 100Mbit / s, and these wireless broadband access systems strengthen the support for terminal mobility, which poses a challenge to the traditional cellular mobile communication system that is in the development period of 3G . [0003] The Third Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) as a Wideband Code Division Multiple Access (WCDMA) and Time Division Synchronous Code...
