摘要： There is provided load sharing performed by a first processing unit device and a second processing unit device. The load sharing is achieved by the first processing unit device determining a distinct subset of user equipment, UE, from a set of UEs, where the UEs of the distinct subset of UEs are candidates for load sharing. Information identifying the UEs in the distinct subset and information of load of a first cell in which the distinct subset of UEs are served and information of load of a second cell being a candidate cell for serving the distinct subset of UEs is transmitted to the second processing unit device. Based on evaluating the information received from the first processing unit device the second processing unit device determines a load sharing action for use by the first processing unit device.

摘要： A method performed by a first network node, for transmitting a RLC UM, PDU, to a second network node is provided. The first network node and second network node operate in a wireless communications network. When detected that the RLC UM PDU has failed to be transmitted over a first channel, the first network node decides (202) to redirect the RLC UM PDU to be transmitted over a second channel. The first network node divides (203) the RLC UM PDU into two or more re-segmented RLC UM PDUs. The first network node then transmits (204) the re-segmented RLC UM PDUsto the second network node 120 over the second channel. Each re-segmented RLC UM PDU comprises the following indications: (a) that the re-segmented RLC UM PDU is re-segmented, (b) an order indicator related to the re-segmented RLC UM PDU, and (c) whether or not the re-segmented RLC UM PDUis a last re-segmented RLC UM PDU out of the two or more re-segmented RLC UM PDUs.

摘要： Methods and apparatus are disclosed for dynamical DM-RS sequence generation in a wireless communications system. The present application discloses that a Physical Downlink Shared Channel (PDSCH) Resource Element (RE) Mapping and Quasi-Co-Location (PQL) indicator can be used to dynamically modify or update the DM-RS sequence generation parameters at a UE. Both the eNB and the UE generate DM-RS reference signals based on the reconfigured parameters. The eNB transmits the generated DM-RS reference signals to the UE to assist the UE in channel estimation.

摘要： The present invention relates to a method for uplink transmission performed in a wireless terminal served by a radio network node of a wireless communication system and corresponding radio network node method. The method comprises receiving (410) an assignment for an uplink transmission from the radio network node. The method also comprises determining (420) alternative usages of the assignment based on the received assignment. Each alternative usage is associated with a different Demodulation Reference Signal (DMRS). The method further comprises selecting (430) a usage among the alternative usages of the assignment, and applying (440) the selected usage when transmitting uplink data to the radio network node. The method also comprises transmitting (450) the DMRS associated with the selected usage. This alleviates the problem of suboptimal resource assignment from the eNodeB by giving some autonomy to the UE. The UE can thus modify the MCS (modulation or coding), the rank of the MIMO transmission (number of layers), or use only part of the resource allocated, and notifies this change to the eNodeB by selecting an associated DMRS.
摘要翻译：本发明涉及一种在由无线通信系统的无线网络节点服务的无线终端中执行的上行链路传输方法及相应的无线网络节点方法。该方法包括从无线电网络节点接收（410）用于上行链路传输的分配。该方法还包括基于所接收的分配确定（420）分配的替代用途。每个替代使用与不同的解调参考信号（DMRS）相关联。该方法还包括：选择（430）在分配的替代用途中的使用，并且在向无线电网络节点发送上行链路数据时应用（440）所选择的使用。该方法还包括发送（450）与所选择的使用相关联的DMRS。这通过给予UE一些自主权来缓解来自eNodeB的次优资源分配的问题。因此，UE可以修改MCS（调制或编码），MIMO传输的等级（层数），或仅使用分配的资源的一部分，并通过选择相关联的DMRS将该改变通知给eNodeB。
