    Conference Calendar.
    United States Court of Appeals, Fifth Circuit.
    Aug. 28, 2006.
    Tanya K. Pierce, Assistant U.S. Attorney, U.S. Attorney’s Office, Northern District of Texas, Lubbock, TX, Delonia Anita Watson, U.S. Attorney’s Office, Northern District of Texas, Fort Worth, TX, for Plaintiff-Appellee.
    Charles Scott Chambers, Law Office of Charles S. Chambers, Lubbock, TX, for Defendant-Appellant.
    Before DAVIS, SMITH, and WIENER, Circuit Judges.
   PER CURIAM:

Lekema Jabbar Ray appeals the sentence imposed following the entry of his guilty plea to a charge of conspiracy to distribute, possess with intent to distribute, and manufacture more than 50 grams of cocaine base. Ray was sentenced to 135 months of imprisonment and five years of supervised release.

Ray, who was sentenced after the Supreme Court issued its opinion in United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005), asserts that because the district court sentenced him within the sentencing guidelines range, the district court treated the Guidelines as mandatory in violation of Booker. In addition to considering the factors contained in 18 U.S.C. § 3553(a), district courts must consider the applicable sentencing guidelines range when sentencing defendants in cases that arise after Booker. United States v. Mares, 402 F.3d 511, 518-19 (5th Cir.), cert. denied, — U.S. -, 126 S.Ct. 43, 163 L.Ed.2d 76 (2005). Further, following Booker, sentences are reviewed for reasonableness. Id. at 518. A sentence within the applicable guidelines range, like Ray’s, is presumed to be reasonable. See United States v. Alonzo, 435 F.3d 551, 553-54 (5th Cir.2006).

Ray also asserts that this court’s decision in Mares is erroneous. Ray’s challenge to Mares is unavailing. One panel of this court may not overrule or ignore a prior panel decision. United States v. Walker, 302 F.3d 322, 325 (5th Cir.2002).

Ray further asserts that sentencing him under the belief that the Guidelines were mandatory constitutes a structural error. The record demonstrates that the district court did not sentence Ray under the belief that the Guidelines were mandatory. Additionally, a Booker error is not structural error. United States v. Malveaux, 411 F.3d 558, 561 n. 9 (5th Cir.), cert. denied, — U.S. -, 126 S.Ct. 194, 163 L.Ed.2d 209 (2005).

AFFIRMED. 
      
       Pursuant to 5th Cir. R. 47.5, the court has determined that this opinion should not be published and is not precedent except under the limited circumstances set forth in 5th Cir. R. 47.5.4.
