    Abstract: According to some embodiments, a method for use in a user equipment (UE) operable to transmit a sounding reference signal (SRS) on a plurality of carriers comprises: obtaining an indication to perform SRS carrier-based switching for a carrier; adapting a parameter for uplink transmit power control in response to the obtained indication; and transmitting an uplink signal using the adapted parameter while meeting at least one predetermined uplink power control requirement. According to some embodiments, a method for use in a network node operable to receive a SRS on a plurality of carriers comprises: sending, to a UE, an indication to perform SRS carrier-based switching for a carrier; and receiving, from the UE, an uplink signal based on the parameter for uplink transmit power control adapted in response to the sent indication, wherein the uplink signal meets at least one uplink power control requirement.

    Abstract: A User Equipment (UE) is described. The UE decodes an uplink/downlink (UL/DL) reconfiguration downlink control information (DCI) with an enhanced interference mitigation with traffic adaptation (eIMTA)-radio network temporary identifier (RNTI) on a physical downlink control channel (PDCCH). The UE also determines if one or more valid UL/DL configurations in the UL/DL reconfiguration DCI with eIMTA-RNTI for all configured eIMTA cells are received. The UE further determines if physical uplink control channel (PUCCH) format 3 is configured. The UE additionally determines a PUCCH resource for physical downlink shared channel (PDSCH) hybrid automatic repeat request acknowledgement/negative acknowledgement (HARQ-ACK) reporting based on whether valid UL/DL configurations in the UL/DL reconfiguration DCI with eIMTA-RNTI for all of the configured eIMTA cells corresponding to a subframe for the PUCCH resource are received. The UE also sends PDSCH HARQ-ACK information on the selected PUCCH resource in an uplink subframe.

    Abstract translation: 描述用户设备(UE)。 UE在物理下行链路控制信道(PDCCH)上用业务自适应(eIMTA) - 射线网络临时标识符(RNTI)对具有增强的干扰减轻的上行链路/下行链路(UL / DL)重配置下行链路控制信息(DCI)进行解码。 UE还确定是否接收到针对所有配置的eIMTA小区的具有eIMTA-RNTI的UL / DL重新配置DCI中的一个或多个有效的UL / DL配置。 UE还确定物理上行链路控制信道(PUCCH)格式3是否被配置。 UE还基于用于所有的具有eIMTA-RNTI的UL / DL重配置DCI中的有效UL / DL配置来确定用于物理下行链路共享信道(PDSCH)混合自动重传请求确认/否定确认(HARQ-ACK)报告的PUCCH资源 被配置的与PUCCH资源的子帧对应的eIMTA信元被接收。 UE还在上行链路子帧中对所选择的PUCCH资源发送PDSCH HARQ-ACK信息。
