摘要： Scheduling of delay-sensitive downlink traffic in a downlink carrier aggregation scenario is performed in such a way as to take advantage of the unambiguous HARQ feedback that is available when the downlink assignment is transmitted coincident with an uplink TDD subframe on the secondary carrier. An example method, in a wireless network node supporting downlink carrier aggregation of a primary carrier in Frequency— Division Duplexing, FDD, mode and a secondary carrier in Time-Division Duplexing, TDD, mode, includes determining (710) that a first user device supported or to be supported with said downlink carrier aggregation has delay-sensitive downlink traffic. Subsequent scheduling of the first user device' s delay-sensitive downlink traffic is prioritized (720) in transmission-time intervals, TTIs, in which the subframe of the secondary carrier is an uplink subframe. The delay-sensitive downlink traffic may be voice-over-Internet-Protocol, VoIP, traffic, for example.

摘要： A method of a radio base station (10) for interpreting multiplexed HARQ feedback data received from a wireless communication device WD (11) in response to a downlink transmission to the WD (11 ). The method comprises receiving (S101 ), in response to a downlink transmission, a multiplexed HARQ feedback data set from the wireless communication device (11) and acquiring (S102) information indicating each possible combination of reception status of Downlink Control Information (DCI) and decoding status for associated Physical Downlink Shared Channel (PDSCH) data received at the WD (11), the information further indicating a multiplexed HARQ feedback data set transmitted by the WD (11 ) for each of the combinations and whether or not there is ambiguity as to if one or more Negative Acknowledgements (NACKs). Determining (S103) if the feedback data set includes one or more NACKs indicated to be ambiguous, and if so computing (S104), for each received NACK determined to indicate ambiguity, a weight indicating probability that the NACK is a result of failed decoding of PDSCH data, based on the acquired information.

摘要： A wireless communication device (16A) is configured to receive user data from a radio network node (18) in a wireless communication system (10)that includes a data channel (26) over which user data is transmitted and a control channel (24) over which control data is transmitted. The device (16A) receives over the control channel (24) a hierarchically-modulated symbol (28) which conveys control data on a control-data modulation layer (30A) and conveys user data on a user-data modulation layer (30B). The control-data modulation layer (30A) is recoverable via demodulation at a lower order, and the user-data modulation layer (30B) is recoverable via demodulation at a higher order. The lower order is lower than the higher order and is generally predefined independent of conditions on the control channel (24). The device (16A) recovers the user data received over the control channel (24) by demodulating at least the user-data modulation layer (30B) at the higher order.

摘要： To relieve signaling congestion, UEs (30) having delay-tolerant data are moved more rapidly to the non UL synchronized state, freeing up PUCCH resources for users that have not indicated a delay-tolerance. In one embodiment, a resource conservative mode is defined for a UE (30) having delay-tolerant data (e.g., from a "background" app); otherwise, the UE (30) assumes a default mode. In one embodiment, the network sends the UE a pair of first and a second values (or indices to them) for a Time Alignment Timer, TAT (56, 66) in the UE (30). The first value - which is typically smaller than the second value - is used by the UE (30) in the resource conservative mode when the user data plane is internally concluded as being delay- tolerant or has already been confirmed to be delay-tolerant; the second value is used otherwise (i.e., in default mode). In the resource conservative mode, the shorter TAT value moves the UE from PUCCH more rapidly, and the UE (30) uses random access for infrequent scheduling requests. In the default mode, the UE (30) retains PUCCH and has low latency for scheduling requests. The network may preconfigure the pair of TAT values. The mechanism is furthermore capable of achieving a synchronized start of a TAT value, and also stopping any TAT (56, 66) that is running.

摘要： Methods, network nodes and wireless device for setting an electrical tilt of an antenna array toward a distribution of wireless devices are disclosed. According to one aspect, a method includes for each of at least one sector of an area covered by the antenna array, determining a function of precoding matrix indicators, PMIs, received from a plurality of WDs in the sector. The method includes determining a current electrical tilt angle of the sector based on the function of PMIs. The method further includes comparing a difference between the current electrical tilt angle of the sector and a previously determined electrical tilt angle of the antenna array to a first threshold, and setting the electrical tilt angle of the antenna array based on the comparison.

摘要： A transmission scheme for transmitting control data segments over a control channel using multi-layer or hierarchical modulation is disclosed. According to principles described herein, first and second control data segments are modulated to form multi-layer symbols configured such that the first control data segment is recoverable via demodulation at a lower order while a second control data segment is recoverable via demodulation at a higher order. In at least some embodiments, the scheme dynamically adapts this higher order to current channel conditions so as to maximize the control channel's spectral efficiency, while at the same time still allowing the system to statically fix the modulation order for the first control data segment, e.g., to maintain (blind) decoding complexity. By transmitting control data in segments using multi-layer modulation, spectral efficiency of the control channel may be improved.
摘要翻译：公开了一种用于使用多层或分层调制在控制信道上传输控制数据段的传输方案。根据在此描述的原理，第一和第二控制数据段被调制以形成多层符号，所述多层符号被配置为使得第一控制数据段可经由较低阶的解调来恢复，而第二控制数据段可经由较高阶的解调来恢复。在至少一些实施例中，该方案动态地将这个较高阶调整为当前信道条件，以使控制信道的频谱效率最大化，同时仍允许系统静态地固定第一控制数据段的调制阶数，例如，以维持（盲目）解码复杂度。通过使用多层调制以分段传输控制数据，可以改善控制信道的频谱效率。

摘要： Systems and methods relating to an unacknowledged connection release in a cellular communications network are disclosed. In some embodiments, a method of operation of a base station in a cellular communications network comprises sending a connection release message to a wireless device that is in an Out-of-Sync (OOS) state and releasing a connection with the wireless device without receiving, from the wireless device, an acknowledgement of receipt of the connection release message. In this manner, signaling overhead for releasing the connection of the wireless device that is in OOS state is substantially reduced.
