摘要： A computer implemented method for operating an access node includes: generating, by the access node, an initial block and a time-dependent signal for transmission in a channel occupancy time (COT) of a shared communications channel, the initial block including a time-independent initial sequence that enables the initial block to be transmitted over any slot in the COT, wherein the time-dependent signal is transmitted after the initial block; and transmitting, by the access node, the initial block and the time-dependent signal in a first slot of the COT. An access node is also described.

摘要： Current HARQ procedures for grant-based uplink transmissions may not be suitable for implementations in which a UE can simultaneously transmit multiple transport blocks (TBs) to a base station. However, in some scenarios, such as in some grant-free uplink transmission schemes, a UE may simultaneously transmit multiple TBs. Systems and methods are disclosed herein for performing HARQ for situations in which a UE simultaneously transmits multiple TBs to a base station. By using the systems and methods described herein, HARQ may therefore be performed in such situations.

摘要： Methods and devices are provided to enable a cooperating group of user equipments (UEs) to access a second spectrum band as frame based equipment (FBE) for device-to-device (D2D) sidelink transmission within the group. In an embodiment, a UE operating as a cooperating UE (CUE) in a cooperating group of UEs receives a group-specific CPC message from the network over a first spectrum band, the group-specific CPC message comprising information related to channel access for transmission of traffic intended for a target UE (TUE). The UE receives traffic intended for the TUE from the network over the first spectrum band and accesses a second spectrum band as FBE in accordance with a set of channel access parameters corresponding to the traffic to relay the traffic to the TUE via D2D sidelink transmission over the second spectrum band.

摘要： A method includes receiving a first assignment for a first transmission with a first hybrid automatic repeat request (HARQ) process identifier (process ID) in a first network resource, receiving a second assignment for a second transmission with a second HARQ process ID in a second network resource, wherein the first network resource and the second network resource differ in a domain other than a time domain, detecting an indication indicating that the first HARQ process ID and the second HARQ process ID map to a same transmission block (TB), and communicating with an access node, a transmission associated with at least one of the first HARQ process ID or the second HARQ process ID.

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： Methods and devices for grant-free uplink transmission in unlicensed spectrum are provided. A base station (BS) transmits grant-free resource configuration information to one or more electronic devices (EDs). The grant-free resource configuration information is used to configure the ED for GF uplink transmission in unlicensed spectrum. The GF resource configuration information includes GF ED group-specific resource configuration information indicating GF ED group-specific time-frequency (T/F) resources of the unlicensed spectrum for GF uplink transmission. The ED(s) transmit grant-free uplink transmissions over the unlicensed spectrum in accordance with the GF resource configuration information.

摘要： Systems and methods for two-step random access procedure are described. According to embodiments, a user equipment (UE) transmits a random access preamble on a random access channel. The UE also transmits data on an uplink data channel using a particular uplink data channel resource. The particular uplink data channel resource is selected by the UE based on the random access preamble.
