Abstract:
The invention relates to a method for efficiently performing power control in situations where the UE is connected to both a MeNB and SeNB. The MeNB determines a power distribution ratio for the power to be used by the UE for uplink transmission to the MeNB and SeNB, determines the parameters P EMAX,MeNB and P EMAX,SeNB and sends these parameters to the SeNB/UE for use in power control. Moreover, update of the power distribution ratio is performed by the MeNB with assistance by the UE, which provides the MeNB with information on the pathloss on the secondary radio link to the SeNB, preferably by transmitting a virtual power headroom report, regarding the secondary radio link to the SeNB, to the MeNB, from which the MeNB derives the information on the pathloss for the secondary radio link.

Abstract:
There are provided a wireless communication apparatus, method and system. The apparatus, at a first node, comprises: a transceiver, operative to transmit and/or receive radio signal; a circuitry, operative to measure one or more channel busy ratios for channel resource pools of the radio signal, and perform congestion control on the channel resource pools based on the measured channel busy ratios.
Abstract:
The present disclosure relates to systems and methods for transmitting data over a wireless channel from a data transmitting node to a data receiving node in a communication system. In particular, the data transmitting node comprises second-layer processing circuitry for receiving, from a third layer, at least one second-layer service data unit, SDU, to be mapped onto a resource allocated for data transmission, and for generating a second-layer protocol data unit, PDU, including said at least one second-layer SDU and at least one second-layer control element, the at least one second-layer control element placed after any of the at least one second-layer SDU, and first-layer processing circuitry for receiving the second-layer PDU generated by the second-layer processing circuitry and mapping the second-layer PDU onto the resource allocated for data transmission. The data receiving node comprises first-layer processing circuitry for de-mapping at least one second-layer protocol data unit, PDU, from a resource allocated for data reception, and a second layer processing circuitry for receiving and parsing the second-layer PDU de-mapped by the first-layer processing circuitry, the second-layer PDU including at least one second-layer service data unit, SDU, and at least one second-layer control element, the at least one second-layer control element following any of the at least one second-layer SDU.
Abstract:
Provided are a wireless device and a wireless communication method in a wireless communication network comprising multiple wireless devices capable of communicating with each other directly, the wireless device comprising: a processing circuitry operative to multiplex data with a scheduling assignment message, into transmission information; and a transmitter operative to transmit the transmission information in a scheduling assignment period, to another wireless device in the wireless communication network, wherein the scheduling assignment message is used for indicating data transmission resource in the scheduling assignment period or in a previous scheduling assignment period.
