摘要： A method performed by a wireless device for wireless transmission of data to a network node of a wireless communication network. The method comprises receiving, from the network node, at a first time slot, a first scheduling grant instructing the wireless device to transmit first data to the network node at a third time slot, and receiving, from the network node, at a second time slot later than the first time slot but earlier than the third time slot, a second scheduling grant instructing the wireless device to transmit second data to the network node at the third time slot. The method further comprises transmitting, to the network node at the third time slot, the second data, and possibly also the first data, in uplink transmission resources of the third time slot, wherein the transmission is performed in accordance with an instruction.

摘要： A method performed by a network node for allocating reference signals to a set of sector carriers provided by the network node for a communication with a UE in a radio network is provided. The network node allocates reference signals to each respective sector carrier, by for each respective sector carrier, allocating a reference signal to the sector carrier, and a parameter representing the sector carrier. The network node transmits the reference signal in each respective sector carrier and evaluates a neighboring relationship between the sector carriers, to identify if two neighboring sector carriers within the one or more cells are allocated the same reference signal. When identified that two neighboring sector carriers are allocated the same reference signal within one or more cells comprising the sector carriers, the network node re-allocates at least one of the two neighboring sector carriers with another available reference signal.

摘要： Embodiments herein relate to a method, performed by a network node (110) in a wireless communication system (100), for handling resource allocations for a first User Equipment, UE (120a) out of a set of UEs (120). Each of the UEs (120) in the set of UEs 5(120) has a different pre-configured frequency allocation for cyclic transmissions, such as cyclic UL and/or DL transmissions. The network node (110) determines, based on a data arrival pattern, such as e.g. a packet arrival time, of the cyclic UL transmissions for each of the UEs in the set of UEs (120), one or more TTIs, where a collision between transmissions to and/or from two UEs (120) out of the set of UEs (120) may occur. The 10 network node (110) reconfigures the frequency allocation for a first UE (120a) of the two UEs (120) to overlap, at least partly, with the frequency of a second UE (120b) of the two UEs (120) for the TTIs other than the TTIs where the collision between the transmissions to and/or from the first and the second UEs (120a, 120b) may occur. Embodiments herein further relate to a method, performed by the first UE (120a) out of the set of UEs (120) in 15 the wireless communication system (100), for handling resource allocation for the first UE (120a) out of the set of UEs (120).

摘要： A method and node for uplink scheduling of a plurality of wireless devices in a communications network is provided. The method includes estimating, for each of a plurality of wireless devices, a buffer size corresponding to each of at least one radio bearer group (RBG), each of the at least one RBG being used by the wireless device to carry traffic via multiple bearers. The method further includes determining an uplink resource maximum allotment for each wireless device based, at least in part, on the estimated buffer sizes and a priority weight of each RBG used by the plurality of wireless devices. The priority weight of each RBG is based at least in part on quality of service (QoS) requirements of bearers carried by the RBG.

摘要： Embodiments herein relate to a method performed by a radio node (13) for managing communication of one or more wireless devices (10) within a wireless communication network (1); which wireless communication network (1) comprises a radio access network node (12) serving the radio node (13). The radio node (13) receives an indication of radio resources out of a total spectrum of radio resources controlled by the radio access network node (12) for communication over a first radio interface using a first radio access technology, which indicated radio resources are allocated to the radio node (13) from the radio access network node (12) for communication over a second radio interface, which second radio interface uses a second radio access technology being different than the first radio access technology. The radio node (13) allocates at least part of the indicated radio resources for communication to and/or from the one or more wireless devices (10) over the second radio interface.

摘要： The disclosure relates to a method performed in a network node of a communication system for configuring a communication device with channel state information, CSI, resources. The method comprises: configuring CSI resources for at least two sectors, the CSI resources comprising CSI reference signal, RS, resources and CSI interference measurements, IM, resources, such that the sectors are configured with same CSI IM resources, and such that each of the sectors is configured with CSI RS resources differing from the other sectors; and configuring the communication device to use a respective CSI resource configuration for each of at least two CSI processes, wherein each CSI resource configuration defines resources corresponding to resources of the configuring of a respective sector, whereby each CSI process specifies use of same CSI IM resources as the other CSI processes and CSI RS resources different from the other CSI processes.

摘要： Embodiments include methods for a user equipment (UE) configured to operate in a wireless network according to a periodic discontinuous reception (DRX) cycle that includes periodic DRX on durations. Such methods include awakening for at least a first duration from a low energy consumption state. The first duration is not within any of the periodic DRX on durations. Such methods include, during the first duration, monitoring for an activation signal occurring at a first offset before a next subsequent resource of a configured grant of periodic uplink transmission resources (UL CG) or of a semi-persistent schedule of periodic downlink reception resources (DL SPS). Other embodiments include complementary methods for a network node, as well as UEs and network nodes configured to perform such methods.

摘要： A wireless communication device (412) replicates, at a Radio Link Control (RLC) layer of a protocol stack of the wireless communication device (412), an original packet associated to a particular service to provide one or more replicate packets. Each of the one or more replicate packets is a replication of the original packet. For each packet from among a set of packets consisting of the original packet and at least one of the one or more replicate packets, the wireless communication device (412) generates a transport block that comprises the packet and transmits the transport block to one or more base stations or transmission/reception points, TRPs, via a physical layer of the protocol stack of the wireless communication device (412).

摘要： Embodiments herein relate to a method implemented by a wireless communication device. The wireless communication device transmits data to a radio node of a wireless communication network. The wireless communication device monitors for a positive acknowledgement or a negative acknowledgement of the data from the radio node. The wireless communication device retransmits the data to the radio node when said monitoring indicates reception of a negative acknowledgement of the data. The wireless communication device refrains from retransmitting the data to the radio node when said monitoring indicates reception of a positive acknowledgement of the data. The wireless communication device also refrains from retransmitting the data to the radio node when said monitoring indicates neither reception of a positive acknowledgement of the data nor reception of a negative acknowledgement of the data.
