PROBLEM TO BE SOLVED: To provide dual domain camping with a single radio UE.SOLUTION: The method includes adaptively sharing a first receive chain and a second receive chain between a first radio access technology (RAT) modem and a second RAT modem of the single radio UE. A single receive chain UE adaptively shares the first and second receive chains to reduce paging collisions between LTE and 1x. A dynamic DRX-cycle modification is performed to increase a DRX cycle so that a percentage of LTE pages affected by sharing of the first and second receive chains is reduced. In addition, the probability of lost data during the 1x tune away is reduced.SELECTED DRAWING: Figure 6 【課題】単一の無線ＵＥを用いたデュアルドメインキャンピングを提供する。【解決手段】方法は、単一の無線ＵＥの第１の無線アクセス技術（ＲＡＴ）モデムと第２のＲＡＴモデムとの間で第１の受信チェーンと第２の受信チェーンとを適応的に共有することを含む。ＬＴＥと１ｘとの間のページング衝突を低減するために、単一の受信チェーンＵＥは第１の受信チェーンと第２の受信チェーンとを適応的に共有する。第１の受信チェーンと第２の受信チェーンとの共有によって影響を受けるＬＴＥページの割合が低減されるようにＤＲＸサイクルを増加させるために、動的ＤＲＸサイクル変更が行われる。また、１ｘチューンアウェイ中の損失データの確率を低減する【選択図】図６
