Abstract: There is provided a method for defining at least one channel reservation window the method comprising: setting length for each of the at least one channel reservation window such that each channel reservation window comprises a plurality of sub-frames; dividing the length of each channel reservation window into a transmission part and an idle part, wherein the idle part consists of one or more symbols in one sub-frame; maximizing, at a symbol level accuracy, the length of the transmission part such that a ratio between the length of the idle part and the length of the transmission part fulfils a predetermined criterion; and concatenating the transmission part and the idle part so as to form the channel reservation window.

Abstract: Various communication systems, such as the long tem evolution advanced (LTE-Advanced) system, may benefit from different configurations for time division duplex (TDD). For example, LTE-Advanced systems may benefit from an enhanced dynamic TDD feature, which may—among other things—reduce latency for LTE-TDD, for example when enhanced interference management and traffic adaptation (eIMTA) is applied. A method can include broadcasting a time division duplex uplink-downlink configuration for a user equipment. The method can also include configuring, via dedicated radio resource control signaling, a downlink hybrid automatic repeat request uplink-downlink reference configuration to a user equipment. The method can further include configuring to the user equipment that at least one new or additional time division duplex uplink-downlink configuration is in use in enhanced operation for a category of user equipment.

Abstract: Methods, apparatuses, and computer program products for defining ARO values in TDD are provided. One method includes defining acknowledgement (Ack)/negative acknowledgement (Nack) resource offset (ARO) values in time division duplex (TDD) with a first set of values and a second set of values. The first set of values contains negative values and is used to offset hybrid automatic repeat request (HARQ) acknowledgment (ACK) resource determination so that HARQ-ACK is transmitted on physical uplink control channel (PUCCH) resources corresponding to another downlink subframe, and the second set of values contains values between −2 and 2.
Abstract translation: 提供了用于在TDD中定义ARO值的方法，设备和计算机程序产品。 一种方法包括利用第一组值和第二组值来定义时分双工（TDD）中的确认（Ack）/否定确认（Nack）资源偏移（ARO）值。 第一组值包含负值，用于抵消混合自动重传请求（HARQ）确认（ACK）资源确定，从而在对应于另一个下行链路子帧的物理上行链路控制信道（PUCCH）资源上发送HARQ-ACK，并且 第二组值包含-2和2之间的值。

Abstract: Various communication systems may benefit from multiplexing schemes. For example, various wireless communication systems may benefit from a block-IFDMA multiplexing scheme with a flexible payload. A method can include determining whether a first type of uplink signal or a second type of uplink signal is to be processed for transmission on an interlace. The method can also include determining whether to apply spreading based on intra-symbol spreading codes, inter-symbol spreading codes, or both intra-symbol spreading codes and inter-symbol spreading codes, based on the determination of whether the first type of uplink signal or the second type of uplink signal is to be processed for transmission. The method can further include causing transmission of the determined at least one of the first type of uplink signal and the second type of uplink signal according to the determination regarding applying spreading.

Abstract: The disclosure relates operation where information of at least one selected resource from a pool of resources for control signals in uplink is signalled in downlink. At least one resource is selected from a pool of resources for control signals in the uplink, where after information of the selected at least one resource is signalled in the downlink. Communication of control signals in the uplink by at least one device is facilitated such that at least one non-selected resource from the pool of resources is used in sending of control signals in the uplink. The at least one resource is implicitly derived in accordance with a predefined rule.

Abstract: A method comprises defining (401), in a network node (e NB), scheduled downlink carriers from a list of configured downlink carriers. The network node (e NB) defines (401) a downlink assignment index of the scheduled carrier having at least the lowest carrier index from the list of configured carriers, based on a total number of scheduled carriers. The network node (e NB) defines (401) the downlink assignment index for each other scheduled carrier having a higher carrier index from the list of configured carriers. The network node (e NB) transmits (402) to a terminal device (UE) a control message corresponding to each scheduled carrier, the control message indicating a downlink assignment scheduling a physical downlink shared channel, and comprising the defined downlink assignment index. The network node (e NB) receives (405) from the terminal device (UE), uplink control signalling indicating HARQ-ACKs related to physical downlink shared channels corresponding to the scheduled carriers.
