Problems solved by technology

In the worst case, the MPR can reach more than 8dB, which is equivalent to reducing the maximum transmit power by 8dB, or equivalent to reducing the adjustable power range by 8dB. In this way, the signal quality transmitted by the UE will be poor, especially When the UE is a cell edge UE, it may cause signal interruption

Embodiment Construction

[0033] The basic idea of ​​the present invention is: after determining that discontinuous RB allocation needs to be performed under the specified channel bandwidth, determine whether the ratio of the number of RBs to be used under the channel bandwidth to the maximum number of RBs that can be used under the channel bandwidth is less than The default value is determined to be less than the value, and discontinuous RB allocation is performed according to the uplink non-consecutive RB allocation constraint strategy.

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] The method for allocating uplink non-consecutive RBs in the present invention, such as figure 1 shown, including the following steps:

[0036] Step 101: After determining that discontinuous RB allocation needs to be performed under the specified channel bandwidth, determine whether the ratio of the number of RBs to ...

Abstract

The invention discloses an allocation method for an upstream discontinuous resource block (RB). The method comprises the steps of determining the allocation of a discontinuous RB in an assigned channel bandwidth, and then judging whether the ratio of the RB value required to be used for the channel bandwidth and the maximum RB value capable of being used for the channel bandwidth is less than a preset value, if so, performing the allocation of the discontinuous RB according to the allocation constraint strategy of the upstream discontinuous RB. The invention also discloses an allocation device for an upstream discontinuous resource block (RB). With the adoption of the allocation method and the allocation device for the upstream discontinuous resource block, the maximum transmitting power return (MPR) due to resource allocation is effectively reduced, thereby ensuring the transmitting power of user equipment (UE) and further guaranteeing the quality of the signal sent by the UE.

Description

technical field [0001] The present invention relates to long-term evolution (LTE, Long-Term Evolution) and enhanced LTE (LTE-Advanced) wireless communication technology, in particular to an uplink discontinuous resource block (RB, Resource Block) allocation method and device. Background technique [0002] In LTE and LTE-Advanced systems, during data transmission, uplink / downlink time-frequency domain physical resources are formed into RBs, and RBs are used as physical resource units for scheduling and allocation. According to the standard protocol of the Third Generation Partnership Project (3GPP, Third Generation Partnership Projects), in the case of a normal (Normal) cyclic prefix (CP, cyclic prefix), an RB contains twelve consecutive subcarriers in the frequency domain. The time domain includes seven consecutive Orthogonal Frequency Division Multiplexing (OFDM, Orthogonal Frequency Division Multiplexing) symbols, that is, the frequency domain bandwidth is 180 KHz, and the...
