摘要： A method of operating a wireless device in a wireless communication network is provided. The method includes reporting channel state information (CSI) by generating, at the wireless device, a CSI report for transmission to a network node that uses the CSI report to make a scheduling decision, dividing the CSI report into a first CSI report portion and a second CSI report portion. The first CSI report portion includes a first payload of data and the second CSI report portion includes a second payload of data that is less than the first payload of data. The first CSI report portion is transmitted on a transmission time interval (TTI) having a first time interval value and the second CSI report portion is transmitted on a short TTI (sTTI). The first CSI report portion and the second CSI report portion include data that is combined to construct the CSI report.

摘要： A user equipment (UE) that performs control signal transmission according to a single-segment subframe format is described. In an aspect, the UE selects a single-segment subframe format as an uplink transmission format for a subframe instead of a multi-segment subframe format. This selection may be based on an indication received by a network node that the single-segment subframe format is to be used for transmission of the one or more control signals. In addition, the UE transmits the one or more control signals on an uplink control channel using the single-segment subframe format.

摘要： It is presented a method for control of Transmission Time Interval (TTI) combinations in multicarrier High Speed Uplink Packet Access (HSUPA). The method is performed in a serving node of a communication network and comprises sending a single High Speed Signalling Control Channel (HS-SCCH) order for TTI switching of a primary Uplink (UL) frequency and for TTI switching of a secondary uplink frequency to a user equipment. It is also presented a serving node, a user equipment, a computer program and a computer program product thereof.

摘要： A method, network node and wireless device for position reference signal (PRS) design by extending a base signal are disclosed. According to one aspect, a method in a wireless device (WD) includes obtaining extended reference signal, RS, configurations from the network node. The method also includes determining a waveform associated with the extended RS. The method also includes detecting a RS and estimate an associated time of arrival. The method further includes sending a measurement report to the network node based on the estimated time of arrival.

摘要： Methods, wireless devices and network nodes for avoiding collision between a downlink control channel and a aperiodic channel state information reference signal, aperiodic CSI-RS, are provided. According to some aspects, a method is provided that includes receiving an aperiodic channel state information reference signal, aperiodic CSI-RS, based on an assumption that the aperiodic CSI-RS is not present in physical layer resources corresponding to a downlink control channel set.

摘要： A threshold condition formed relative to the strongest peak (e.g., in a signaled DL-PRS-specific search window) is used in the search for the first peak to be used for Time of Arrival (TOA) estimation. Such a threshold condition may be used with DL-PRSs that are homogenous or inhomogeneous, and in each of these combined (or not) with cyclic shifts. In so doing, the solutions 0 (100, 200, 300, 400) presented herein avoid detecting false peaks.
