摘要： Downlink congestion is accurately detected and congestion control is more effectively provided without decreasing the system downlink capacity. The characteristics of the downlink transmission of the base station are monitored and used to selectively adjust a fast congestion control (FCC) alarm threshold value in each base station. A FCC relief action is initiated upon detecting the downlink power exceeding the FCC alarm threshold value, i.e., potential downlink congestion. The FCC relief action includes temporarily blocking data services in the system or rapidly decreasing the downlink transmit power of the packet data user's Dedicated Physical Channels in the base stations.

摘要： A method for verifying data integrity in a receiver in a wireless communication network is disclosed. The method comprises receiving (101) a data message, wherein the data message comprises a group of data elements and a checksum, computing (102) a complete syndrome vector based on partial syndrome vectors, wherein the partial syndrome vectors are computed, in parallel, by multiplying part of a parity-check matrix with corresponding part of the received data message, determining (103) that all vector elements of the complete syndrome vector are zero, and verifying (104) that the received data message is correct (104a) when all the vector elements of the complete syndrome vector are zero, and incorrect (104b) otherwise. Corresponding computer program product, apparatus, and receiver are also disclosed.

摘要： There is provided mechanisms for decoding an encoded sequence into a decoded sequence. A method is performed by an information decoder. The method comprises obtaining a channel output. The channel output represents the encoded sequence as passed through a communications channel. The encoded sequence has been encoded using a polar code. The polar code is representable by a code diagram. The method comprises successively decoding the channel output into the decoded sequence by traversing the code diagram. The method comprises, whilst traversing the code diagram, determining a bit score term for each potential decoding decision on one or more bits being decoded. The method comprises, whilst traversing the code diagram, adding an adjustment term to each bit score term to form a candidate score for said each potential decoding decision. The successive decoding is repeated until all bits of the channel output have been decoded, resulting in at least two candidate decoded sequences. The method comprises discarding all but one of the at least two candidate decoded sequences, resulting in one single decoded sequence.

摘要： The present disclosure relates in general to radio network communication. In one of its aspects, the technology presented herein concerns a method in a transmitting radio unit for providing data in a control message to a receiving radio unit. The data comprises a first data part that have stricter time requirements for decoding than a second data part of the data. The first data part is mapped to a first message part of the control message and the second data part is mapped to a second message part of the control message. The control message is encoded, so that the first message part is decoded prior to the second message part.

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： Systems and methods are disclosed for providing efficient downlink Hybrid Automatic Request (HARQ) feedback. In some embodiments, a method of operation of a wireless device in a cellular communications system comprises receiving downlink control information from a radio access node in a first subframe T. The downlink control information comprises an indication of a HARQ timing offset K. The method further comprises transmitting downlink HARQ feedback to the radio access node in a subframe T+K. In this manner, HARQ feedback can be directly scheduled by the network, which in turn enables efficient HARQ feedback.

摘要： Embodiments described herein are directed to methods for controlling user equipment (UE) beamforming in a wireless network. According to certain embodiments, a (UE) can receive one or more beam reference signals included in a restricted set of useable beam reference signals for adjusting the UE beamforming. Further, the UE can receive one or more beam reference signals outside of the restricted set. It can be determined whether to update the restricted set to include a subset of the one or more beam reference signals outside of the restricted set, based on predetermined criteria. The UE beamforming can be adjusted based on beam reference signals in the restricted set.
