摘要: A method for dynamically dividing or consolidating sub-bands in-between Clear Channel Assessment (CCA) status measurements upon detection of a CCA bandwidth adjustment condition is provided. The method includes determining at least a single CCA status for at least a single sub-band during a first period, and detecting a CCA bandwidth adjustment condition for dividing the single sub-band into two or more separate sub-bands, where a combination of the two or more separate sub-bands occupies the same frequency band as the single sub-band. The method also includes determining a separate CCA status for each of the two or more separate sub-bands during a second period. An apparatus for performing this method is also provided.

摘要: Operational and environmental efficiency in virtual radio access networks (VRANs) can be improved by offloading data traffic and/or control signaling between physical transmit points (TPs) of a virtual TP. This may allow one or more physical TPs of the virtual TP to be muted in the downlink or uplink direction, thereby reducing energy consumption. The offloading may be performed during relatively short time-intervals such that physical TP are muted for one or more transmission time intervals (TTIs) before being re-activated. The offloading may also be implemented over longer time-intervals in accordance with a traffic engineering (TE) policy. Further it is possible to re-activate a de-activated downlink transmitter of physical TP by monitoring wireless signals via an activated receiver of the physical TP.

摘要: A user equipment (UE) may transmit a configured-grant uplink control information (CG-UCI) to a base station during a channel occupancy time (COT) initiated by the UE in a shared spectrum, the CG-UCI comprising COT sharing information, the COT sharing information indicating, at least, an index value corresponding to a combination of: an indication of an offset to a beginning of a downlink transmission opportunity during the COT; an indication of a duration of the downlink transmission opportunity during the COT; and an indication of a channel access priority class (CAPC) value used by the UE to initiate the COT. The base station may transmit a downlink transmission to the UE within the downlink transmission opportunity and in accordance with the COT sharing information in the transmitted CG-UCI. Apparatuses are also disclosed.

摘要: Aspects of the present application provide for flexibility in configuring channel access occasions for uplink transmissions within a configured grant transmission resource duration. The uplink transmission may be transmitted in the physical uplink shared channel (PUSCH). The configured grant transmission resource duration includes multiple orthogonal frequency division multiplexed (OFDM) symbols. In some implementations, resources for uplink transmissions are allocated such that an integer number of equally sized mini-slots, each of which is considered a separate PUSCH, fit within the slot. This occurs when the number of OFDM symbols within the slot is evenly divisible by the number of OFDM symbols in the mini-slot. In some embodiments, not all of the mini-slots in the slot are equal in size. This occurs when the number of OFDM symbols within the slot is not evenly divisible by a particular mini-slot size.

摘要: Some user equipments (UEs) served by a base station may need to receive data from the base station and/or transmit data to the base station with lower latency than other UEs. It is desired to accommodate the presence of both low latency and latency tolerant communications in shared time-frequency resources to try to improve resource utilization. Embodiments are disclosed in which low latency and latency tolerant communications coexist in the same time-frequency resources. In some embodiments, a latency tolerant transmission is postponed to free resources to send a low latency transmission.
