摘要： The present disclosure relates to a technique of prioritizing downlink transmission. More particularly, the present disclosure relates to a technique of prioritizing Downlink transmission in a Time Division Duplex wireless communication system employing a channel sensing mechanism. A method embodiment comprises: transmitting, by an access network node of the wireless communication system, an Uplink, UL, grant to a wireless communication device, the UL grant indicating that an UL transmission is planned in one or more first subframes; and prioritizing, by the access network node, Downlink, DL, transmission in one or more second subframes over the planned UL transmission, the one or more second subframes at least partially overlapping with the one or more first subframes.

摘要： A method and network node for adaptation of contention windows in a multicarrier wireless communication system implementing a listen-before-talk protocol are disclosed. According to one aspect, a method includes determining at least one component carrier (CC), of multiple CCs to serve as a backoff channel. The method further includes performing a listen-before-talk procedure on the at least one CC serving as a backoff channel. The listen-before-talk procedure includes sensing for each backoff channel whether a clear channel exists during a backoff period drawn from a contention window (CW). The LBT procedure also includes deferring transmitting on a CC for which the sensing does not indicate that a clear channel exists. The LBT procedure also includes transmitting on a CC for which the sensing indicates a clear channel exists. The method also includes determining a size of the CW based on at least one transmission feedback value.

摘要： A node of a wireless network transmits information to a user equipment over an aggregated carrier that includes a primary carrier having a first set of primary carrier time/frequency resources and a secondary carrier having a second set of secondary carrier time/frequency resources. Synchronization signals and/or reference symbols are transmitted to the user equipment on the secondary carrier less often than on the primary carrier. An indication of when and/or how often the synchronization signals and/or reference symbols will be transmitted to the user equipment on the secondary carrier may also be transmitted to the user equipment over the primary carrier. By transmitting synchronization signals and/or reference symbols to the user equipment on the secondary carrier less often than on the primary carrier, resources of the secondary carrier may be conserved, energy efficiency of the secondary carrier may be increased, and/or interference with other cells may be reduced or prevented.

摘要： A method, system and apparatus are disclosed for enabling inter carrier interference compensation for interleaved mapping from virtual to physical resource blocks. In one embodiment, a network node is configured to determine to configure the first signal to be located at a subcarrier except at an edge sub-carrier of a resource block, RB; transmit the configuration of the first signal to the WD; and receive a physical uplink shared channel, PUSCH, signaling and the first signal from the WD based at least in part on the determined configuration. In one embodiment, a WD is configured to perform a de-inter-carrier-interference (de-ICI) filter estimation on a first received signal and a second received signal; apply a de-ICI filter to a third received signal, the de-ICI filter being based on the de-ICI filter estimation; and after the application of the de-ICI filter, de-interleaved map and demodulate the third received signal.
