The wireless device (121) determines at least one compatibility state for the two or more beamformed communication links (23-1; 25-2; 25-3; 25-4; 27-2) based on one or more current radio signal characteristics at the wireless device (121) for the two or more beamformed communication links (23-1; 25-2; 25-3; 25-4; 27-2), wherein the at least one compatibility state indicates if the wireless device (121) currently is able to simultaneously receive transmission beams of the two or more beamformed communication links (23-1; 25-2; 25- 3; 25-4; 27-2) from the one or more network nodes (110) or not. Then, the wireless device (121) transmits information indicating the at least one determined compatibility state for the two or more beamformed communication links (23-1; 25-2; 25-3; 25-4; 27-2) to at least one of the one or more network nodes (110). A wireless device (121) for handling two or more beamformed communication links (23-1; 25-2; 25-3; 25-4; 27-2) initialized with one or more network nodes (110) in a wireless communications network (100) is also provided.

摘要： Independent power-control procedures per beam-pair link (BPL). In one embodiment, such a power-control procedure comprises: 1) an open-loop part based on the estimated DL path loss for the active and back-up (or "non-active") BPLs in the UE and 2) a closed-loop part where the UL power-control adjustment commands are transmitted from the network and accumulated in the UE independently per active BPL. The UL transmit power is determined from the power- control procedure associated with the active BPL scheduled for transmission.

摘要： A method performed by a radio-network node for handling a data transmission from the radio-network node to a wireless device in a wireless communication network is provided. The radio-network node transmits (401) data over a number of subframes to the wireless device (10), and a respective control part, associated with the data of each respective subframe, the respective control part comprising a feedback index indicating a transmission time of a feedback indication. The radio-network node receives (402) from the wireless device the feedback indication in the feedback message common for the subframes of the data transmission according to the control parts of the transmitted subframes. The feedback indication indicates feedback for each subframe of the data transmission received and the number of NACKed subframes out of the number of subframes of the data transmission. The radio-network node receives the feedback message and then decides (403) whether or not to retransmit any of the subframes based on the feedback indication therein.

摘要： Beam Reference Signal (BRS) structure for LTE, but inspired from the IEEE STF and LTF structure by introducing within an IFFT period a repetition pattern in time domain by populating only every N subcarriers (the other subcarriers being set to zero). Furthermore the DC subcarrier is blanked or zeroed so that the resulting BRS tones are symmetric around the DC subcarrier. The resulting BSR repeated symbols have therefore a much shorter duration than conventional LTE symbols and allows for a quicker beamforming measurement and weight update, by allowing the UE to perform measurements on these reference signals using different receive-beam configurations for each BSR instance.
摘要翻译：用于LTE的波束参考信号（BRS）结构，但是通过在IFFT周期内通过在时域中引入重复模式，通过仅填充每N个子载波（其他子载波是设置为零）。此外，DC副载波被消隐或归零，使得所得到的BRS音调在DC副载波周围是对称的。所得到的BSR重复符号因此具有比常规LTE符号短得多的持续时间，并且允许UE使用针对每个BSR实例的不同接收波束配置对这些参考信号执行测量，从而允许更快的波束成形测量和权重更新。 p>

摘要： According to some embodiments, a method in a wireless receiver of compensating common phase error in a received wireless signal comprises receiving a first symbol of a wireless signal. The first symbol comprises a code division multiplexed demodulation reference signal (DM-RS) multiplexed with a length M orthogonal cover code, and a first code division multiplexed common phase error reference signal (CPE-RS) multiplexed with a length N orthogonal cover code, wherein N is less than or equal to M. The method further comprises determining M code points in the first symbol associated with a DM-RS; estimating a channel corresponding to the received wireless signal using the M code points associated with the DM-RS; estimating a first CPE-RS corresponding to the estimated channel using the first N code points of the M code points associated with the DM-RS; and compensating the estimated channel for phase error using the estimated first CPE-RS.
