摘要： A system, method (400), and network node (102) is presented for setting the size of a control region, the PDCCH region (201) of a subframe (200). The PDCCH control region may have a size, indicated by the Control Format Indicator, CFI, transmitted on the PCFICH, that varies between 1 and 3 OFDM symbols. The network node (102) may select (402) an initial size for the control region (201), and determine (404) whether the initial size for the control region is less than a predetermined maximum control region size. In response to determining that the initial size is less than the predetermined maximum control region size, the network node (102) selects (406) a final size for the control region (201) based on a data region load. The data region load indicates a load on all physical downlink shared channels, PDSCHs, on all enhanced PDCCHs, ePDCCHs, in the data region. After selecting the final size for the control region, the network node (102) transmits (408) the subframe (200), wherein the control region of the subframe comprises information identifying the selected final size, and the size of the control region is equal to the selected final size.

摘要： A User Equipment (UE) (20) has multiple transceivers, each having a corresponding receiver configured to communicate on respective carriers. The UE (20) monitors a radio access network (RAN) (16) on a serving cell using a first of the receivers, and indicates to the base station (80) that at least one of its receivers will temporary tune-out from the RAN (16). The base station (80) receives the indication from the UE (20), and temporarily suspends communications with the UE (20).

摘要： With multiple connections (20) communicatively coupling a User Equipment (UE) (12) to a wireless communication network (10), methods and apparatuses disclosed for performing flow control at the Radio Link Control (RLC) level advantageously control the shares of overall data conveyed on the respective connections (20) in a manner that accounts for changing conditions on the involved radio links (22) while accommodating signaling delays and other complexities that arise from distributed or virtualized implementations of the underlying processing apparatuses (18). The disclosed methods and apparatuses have applicability both to uplink multi-connectivity and downlink multi-connectivity, and apply to various multi-connectivity scenarios, including scenarios involving mixed Radio Access Technologies (RATs) and Carrier Aggregation (CA) configurations that aggregate two or more Component Carriers (CCs) for carrying user traffic between a UE (12) and the network (10).

The method comprises determining to transmit DL data to the UE (120) in the control region subset, when the amount of DL data for the UE (120) is less or equal to a threshold. Embodiments herein further relate to a radio network node (110) in a RAN, for scheduling DL data for a UE (120) in a control region subset (140). The radio network node (110) is configured to perform the method for scheduling DL data in a control region subset (140).

摘要： A method for radio communication between a transmitting node and receiving nodes comprises obtaining (Sl) of directions from the transmitting node to the receiving nodes and antenna gains needed for each direction. A beam forming solution having a high gain in the directions of a set of receiving nodes and with antenna gains adapted to the need of the link is obtained (S2). User data to be transmitted to the receiving nodes is obtained (S3). The user data is overlay-coded (S4) by a code-domain overlaid code and/or a frequency-domain overlaid code, separately for each respective receiving node. The overlaid-coded user data is combined (S5) into at least one combined signal stream. Analogue beamforming, hybrid beamforming or constrained beamforming is performed (S6) on the combined signal stream(s) according to the beam forming solution. The beamformed data is transmitted (S7) from the transmitting node to the receiving nodes.

摘要： A method includes a base station in a distributed antenna system having a set of antennas. For each antenna, the base station stores state information indicating that the antenna is either in a transmit state or a do_not_transmit state. For each antenna indicated by the state information for the antenna as being in the transmit state, the base station determines whether the antenna has been given a clear channel indication (CCI) for a next transmission time interval (TTI). At the next TTI, the base station transmits data to a UE, wherein the base station transmits the data to the UE using antennas included in said set of antennas that i) are indicated by the state information for the antenna as being in the transmit state and ii) have been given the CCI. The base station adjusts the state information in accordance with a transmit status.

摘要： Selecting a downlink control information (DCI) format used for transmitting a DCI message in a subframe. The subframe may be used to carry, for instance, voice communication data to support a voice over LTE (VoLTE) application or to otherwise provide downlink (DL) voice coverage. In one aspect, a certain downlink DCI format is selected (e.g., DCI format 1A) when there is a high path loss and/or interference scenario, and/or the packet has data with a high priority (e.g., low QCI value). This technique may lead to less dropped calls due to RTP timeout, and may improve perception and mean opinion score (MOS) of VoLTE quality.
摘要翻译：选择用于在子帧中发送DCI消息的下行链路控制信息（DCI）格式。该子帧可以用于携带例如语音通信数据以支持通过LTE的语音（VoLTE）应用或者以其他方式提供下行链路（DL）语音覆盖。在一个方面，当存在高路径损耗和/或干扰情况，和/或分组具有高优先级（例如，低QCI值）的数据时，选择某个下行链路DCI格式（例如，DCI格式1A）。这种技术可能会导致由于RTP超时导致的掉话次数减少，并且可能会提高VoLTE质量的感知和平均意见分数（MOS）。
