摘要： Systems and methods are disclosed herein that relate to multiple candidate starting points for a transmit burst in unlicensed spectrum. In some embodiments, a method of operation of a radio access node for performing a transmit burst in an unlicensed spectrum comprises transmitting a transmit burst in an unlicensed spectrum, wherein the transmit burst spans multiple subframes/slots and the transmitting of the transmit burst starts at one of a plurality of candidate starting points defined in at least a first subframe/slot of the transmit burst that occurs after successful completion of a Listen-Before-Talk (LBT) procedure for the transmit burst. In this manner, a radio access node (e.g., an enhanced or evolved Node B (eNB) in Long Term Evolution (LTE)) has flexibility to transmit a downlink transmit burst starting at different starting positions based on LBT outcome.

摘要： Channel state determination is performed at a user equipment (UE) of a mobile network. The UE determines one or a plurality of time intervals that may be used for channel measurements, performs a plurality of signal power measurements associated each to one of the time intervals to be used for channel measurement and generates a channel state information as a function of the plurality of the signal power measurements. Information comprising an indication of a plurality of time intervals that may be used for received signal power measurements is generated and sent from an access node (eNB) to the UE. The eNB evaluates a measurement report, received from the UE, that comprises received signal power measurements associated each to one of the time intervals.

摘要： A method performed by a wireless device for performing an uplink control channel transmission in a serving cell in a wireless communications network is provided. The wireless device is configured with a set of serving cell(s) in the wireless communications network. First, the wireless device determines a number of serving cells of the set of serving cell(s) that are relevant to consider when performing the uplink control channel transmission in the serving cell. Secondly, the wireless device selects an uplink control channel format from a set of uplink control channel formats for uplink control channel transmissions based on the determined number of serving cells. Then, the wireless device performs the uplink control channel transmission in the serving cell using the selected uplink control channel format. A wireless device for performing an uplink control channel transmission in a serving cell in a wireless communications network is also provided.

摘要： Systems and methods for soft buffer handling with limited memory access bandwidth are provided herein. In some embodiments, a method of operation of a User Equipment (UE) of a cellular communications network includes receiving a retransmission that would require a total number of memory accesses to process that is greater than a memory access bandwidth of a soft buffer of the UE. The method also includes prioritizing which bits should be read from or written to the soft buffer of the UE when processing the retransmission based on the memory access bandwidth, any previously received redundancy versions, and/or a currently received redundancy version. According to some embodiments, this achieves higher system performance than Chase Combining alone while keeping the receiver implementation limitation as low as alternative solutions.

摘要： A radio access node or wireless device performs LBT on a channel and dynamically determines a transmission starting point on the channel, based on whether the LBT succeeds before or after a slot boundary between a slot n and a previous slot n−1. In response to determining that the LBT succeeds before the slot boundary, a transmission scheduled for the slot n is extended to start earlier, in the previous slot n−1. Otherwise, in response to determining that the LBT succeeds after the slot boundary, either a transmission scheduled for a next slot n+1 is extended to start earlier, in the slot n, or a transmission scheduled for the a second mini-slot of the slot n is extended to start earlier, in a first mini-slot of the slot n.
