摘要： A first wireless communication device (14-1) belongs to a first (12-1) of multiple groups (12) of wireless communication devices (14). Devices (14) in any given group (12) are synchronized to the same timing reference and devices (14) in different groups (12) are not synchronized to the same timing reference. The first device (14-1) receives a message that indicates, for each of one or more of the groups (12), a range of possible values for misalignment between the timing reference of that group (12) and a common timing reference. The range accounts for uncertainty in that misalignment. The first device (14-1) determines, based on the one or more ranges, intervals of times during which direct control signaling is expected to be received at the first device (14-1) from one or more devices (14) in one or more other groups (12-2, 12-3). The first device (14-1) then adjusts intervals of times during which it is configured to operate in an awake state to narrowly encompass the intervals of times during which the direct control signaling is expected to be received.
摘要翻译：第一无线通信设备（14-1）属于无线通信设备（14）的多组（12）的第一（12-1）。任何给定组（12）中的设备（14）被同步到相同的定时参考，并且不同组（12）中的设备（14）不同步到相同的定时参考。第一设备（14-1）接收消息，该消息针对组（12）中的一个或多个组中的每一个指示用于该组（12）的定时参考与公共定时参考之间的未对准的可能值的范围。该范围解释了这种不对中的不确定性。第一设备（14-1）基于一个或多个范围，确定期望在第一设备（14-1）处从一个或多个设备（14）接收直接控制信令的时间间隔或更多其他组（12-2,12-3）。然后，第一设备（14-1）调整其被配置为在唤醒状态下工作的时间间隔，以狭窄地包含期望接收直接控制信令的时间间隔。

摘要： User Equipment, UE (30), in a wireless radiocommunication network (10) supporting Coordinated Multi-Point, CoMP, transmissions may autonomously adopt an assumption of the quasi co-located (QCL) status of two (or more) antenna ports that is different from the default QCL status defined or signaled by the network (10), in response to one or more estimates of certain operating parameter values. The altered QCL status assumption allows the UE (30) to correct parameter estimates more accurately, and/or to reduce complexity in the parameter estimation correction.

摘要： The present disclosure relates to methods and devices for transmission of discovery signal signals and detection of discovery signal signals for device-to-device communication. According to some aspects, the disclosure relates to a method executed in a second wireless terminal for discovering a first wireless terminal, wherein the second wireless terminal 20 is configured with a set of one or more identities of wireless terminals with which device-to-device, D2D, communication is possible. The method comprises the following steps detecting a control signal transmitted from the first wireless terminal, wherein the control signal carries an identity and decoding S13 the received signal. The wireless terminal then, for each identity in the set, hashes S14 a reference control signal comprising an identity of the wireless terminal, taking a time stamp used for the control signal transmission as one input parameter of the hashing function and determines S15 if an output signal of the hashing matches the decoded signal, until all the identities in the set have been selected or until a match is found.
