Abstract
Official abstract text for this publication.
A user equipment (UE) for reporting uplink control information (UCI) when one or more Licensed-Assisted Access (LAA) serving cells are configured is described. The UE includes a processor and memory in electronic communication with the processor. Instructions stored in the memory are executable to determine if physical uplink shared channel (PUSCH) transmissions are scheduled on LAA serving cells and licensed cells. The instructions are also executable to determine a type of UCI to be reported. The instructions are further executable to determine a channel and cells to carry different UCI. The instructions are additionally executable to transmit the channel on the cells determined to carry UCI. The instructions are also executable to determine whether a LAA PUSCH is transmitted and UCI is multiplexed. The instructions are further executable to drop LAA PUSCH or transmit LAA PUSCH subject to listen-before-talk (LBT).
First claim
Opening claim text (preview).
What is claimed is: 1. A user equipment (UE) comprising: a processor; and a memory in electronic communication with the processor, wherein instructions stored in the memory are executable by the processor to: in a case of an uplink control information (UCI) transmission in a subframe with physical uplink shared channel(s) (PUSCH(s)) and if an aperiodic channel state information (CSI) report is not triggered for the subframe, and if the PUSCH(s) is transmitted only on Licensed-Assisted Access (LAA) secondary cell(s) (SCell(s)), follow a UCI transmission procedure for cases of UCI transmission in a subframe without PUSCH, wherein the UCI includes a periodic CSI report and a hybrid automatic repeat request acknowledgement (HARQ-ACK), and the UCI transmission procedure is a procedure in which the UCI is transmitted on a physical uplink control channel (PUCCH). 2. The UE of claim 1 , wherein the instructions are further executable to: in a case that the PUSCH(s) are transmitted on both the LAA SCell(s) and non-LAA SCell(s) and if simultaneous PUCCH and PUSCH transmission is not configured, transmit the UCI on PUSCH of a non-LAA SCell with a smallest ID. 3. An evolved node B (eNB) comprising: a processor; and a memory in electronic communication with the processor, wherein instructions stored in the memory are executable by the processor to: in a case of an uplink control information (UCI) transmission in a subframe with physical uplink shared channel(s) (PUSCH(s)) and if an aperiodic channel state information (CSI) report is not triggered for the subframe, and if the PUSCH(s) is transmitted only on Licensed-Assisted Access (LAA) secondary cell(s) (SCell(s)), follow a UCI reception procedure for cases of UCI transmission in a subframe without PUSCH, wherein the UCI includes a periodic CSI report and a hybrid automatic repeat request acknowledgement (HARQ-ACK), and the UCI reception procedure is a procedure in which the UCI is received on a physical uplink control channel (PUCCH). 4. The eNB of claim 3 , wherein the instructions are further executable to: in a case that the PUSCH(s) are transmitted on both the LAA SCell(s) and non-LAA SCell(s) and if simultaneous PUCCH and PUSCH transmission is not configured, receive the UCI on PUSCH of a non-LAA SCell with a smallest ID.
