摘要:
A wireless node (e.g. , a slave relay node) may receive scheduling commands over multiple wireless links and identify a scheduling conflict. For example, the wireless node my identify a conflict of wireless resources indicated by the received scheduling commands. The wireless node may select a non-conflicting subset of the scheduling commands based on a conflict policy, and transmit data over the wireless links according to the non-conflicting subset of the scheduling commands. Additionally or alternatively, the wireless node may transmit a conflict report indicating the identified scheduling conflict. The conflict report may be sent to other wireless nodes (e.g. , master relay nodes associated with the conflicting scheduling commands). The other wireless nodes may engage in negotiation signaling to resolve the scheduling conflict, and may transmit an updated scheduling command to the slave relay node. The slave relay node may transmit data over wireless links based on the updated scheduling command.

A method of a network node of a time division duplex (TDD) system is disclosed. The method comprises acquiring a maximum cell synchronization error, determining a number of symbols of a partial uplink subframe (PUSF) based on the maximum cell synchronization error, and transmitting an indication of a PUSF configuration to at least one PUSF capable wireless communication device, wherein the PUSF configuration indicates the determined number of symbols of the PUSF. The method also comprises sending an uplink grant signal to one or more of the at least one PUSF capable wireless communication devices, wherein the uplink grant is for a PUSF immediately preceding another subframe to be used for downlink transmission. Transmitting the indication of the PUSF configuration may comprise broadcasting the indication or including the indication in the uplink grant signal.The method may further comprise receiving an indication of PUSF capability from the at least one PUSF capable wireless communication device, thereby identifying the at least one PUSF capable wireless communication device as PUSF capable. Corresponding computer program product, arrangement and network node are also disclosed.
摘要:
A method and a wireless device (100) for handling transmission of data. The cost for transmitting the data from the wireless device (100) can be reduced or even minimized by delaying (1:3) transmission until the transmission cost becomes lower, provided that the data can wait without becoming obsolete or useless at the receiving side. This is made possible by determining a delay tolerance of the data and determining a cost prediction for transmission (1:6) within said delay tolerance, e.g. when a cheaper connection (1:4) is used. Advantages may include reduced price to pay for the transmission, less energy consumption, and avoided usage of precious radio resources and network resources at times when the traffic load is high.

Embodiments of the present disclosure relate to a method and apparatus for controlling data packet transmission in a D2D communication. The method comprises: obtaining, by a current user equipment, data packet priority information regarding other user equipments; and controlling data packet transmission of the current user equipment based on the data packet priority information. According to the embodiments of the present disclosure, a support mechanism for a data packet priority may be introduced at an access stratum of the D2D communication, thereby supporting preferential transmission of the data packet across different UEs using the data packet priority, further satisfying the priority needs of the application layer, and facilitating a user to use.

The invention relates to a method for scheduling user terminals in a heterogeneous network comprising a plurality of cooperating cells constituted by at least one macro cell and at least one small cell having at least partially overlapping coverage, each cooperating cell having corresponding radio resource blocks assigned to their respective user terminals, wherein for a centralized controller to assign a radio resource block of the macro cell, a utility metric associated with said radio resource block of the macro cell is determined for each combination of user terminal of the macro cell and of a user terminal of the small cell assigned to the corresponding radio resource block, and the radio resource block of the macro cell is assigned to the user terminal of the macro cell that maximizes said second utility metric.
摘要:
A low complexity user equipment (40) includes maximum size restriction, such as a maximum transport block size, for simultaneous downlink transmissions. When the user equipment (40) receives simultaneous downlink transmission exceeding the maximum size restriction, the user equipment (40) is allowed to skip decoding of one or more of the downlink transmission (e.g.,one or more transport blocks) according to a predetermined set of rules.
摘要:
A network node (310) comprising a radio frequency communications interface (230) and a controller (210), said network node (310) being configured to service at least one first radio frequency communication device (320) being configured for both network communication and for device-to-device communication with a second radio frequency communication device (325), wherein said controller (210) is configured to determine if a restriction of a scheduling policy is necessary for said first radio frequency communication device (320), select a scheduling policy accordingly. The controller is further configured to allocate communication resources according to said selected scheduling policy to said first radio frequency communication device (320). The scheduling policy is one which enables simultaneous network communication and device-to-device communication in said same transmission time interval (A, B, C, D, E) or one which enables either network communication or device-to-device communication in said same transmission time interval.
