摘要:
Methods and devices are described for communication using proximity services (ProSe). An aggregate maximum bit rate parameter (AMBR) may limit a data rate that may be transmitted by one or more ProSe bearers. A wireless transmit-receive unit (WTRU) may request authorization from the network prior to establishing a ProSe bearer specifying a required quality of service (QoS) or other requirements. Each ProSe bearer may have a corresponding EPS bearer to support service continuity. Packets may be evaluated by a WTRU first using a ProSe check to determine if the packet is destined for a ProSe bearer and then using a packet filter or filters in order of precedence. Embodiments may include methods of initiation communication after discovery. Embodiments may include methods of maintaining session continuity when traffic is switched between an evolved packet system (EPS) bearer and a ProSe bearer.

Described herein are methods and apparatuses for enhancing transmission reliability. A method may comprise determining to determining to transmit a plurality of repetitions of a data payload. Each repetition of the data payload may comprise a set of coded bit sequences. The method may further comprise determining a constellation for each of the repetitions of the data payload, and mapping, for each repetition of the data payload, the sets of coded bit sequences to respective sets of modulation symbols based on the constellation. Each of the sets of modulation symbols may be different. The method may further comprise allocating time and frequency resources for transmitting the sets of modulation symbols and transmitting the sets of modulation symbols on a downlink channel using the allocated time and frequency resources.

Systems, methods, and instrumentalities are described herein regarding enhancements of physical channels in Multi-TRP. Reliability enhancements are provided for physical downlink control channel (PDCCH), including, for example, enhanced support for a control resource set (CORESET) combining. Reliability enhancements are provided for physical uplink control channel (PUCCH), including, for example, activation/deactivation of repetition combining, resource selection, etc. Reliability enhancements are provided for physical uplink shared channel (PUSCH), including, for example, spatial relation determination and signaling, configured and dynamic grant enhancements, etc.

Systems, methods and instrumentalities are disclosed for beam-based PDCCH Transmission in NR. Control resource sets may be assigned for multi-beam control transmission. A PDCCH may be transmitted with multiple beams. CCEs may be mapped for multi-beam transmission. DCI may support multi-dimensional transmission with primary and secondary dimensions. Search space may support multi-beam, multi-TRP transmission.

Location and other status information may be communicated between Proximity Service (ProSe) users. A ProSe function may retrieve a ProSe WTRU's location data from SLP and provide it to a monitoring WTRU via a ProSe discovery procedure or EPC-level ProSe discovery procedure. A ProSe function may retrieve a ProSe WTRU's location data from a ProSe WTRU and provide it to monitoring WTRUs via a ProSe discovery procedure. A ProSe WTRU may broadcast its location and/or other status information in a discovery message. A ProSe function may encrypt the location and/or other status information for encryption before broadcast. A ProSe WTRU may send its location and/or other status information via a user plane to another ProSe WTRU or ProSe group. A ProSe function may verify whether a WTRU is permitted to disclose and/or process information (e.g., location information) and may indicate to a WTRU whether to disclose information, e.g., before the information is disclosed, and/or whether to process the information.

In one aspect, a method of cell processing is disclosed, which includes disposing a plurality of cells on a substrate across which a plurality of projections are distributed and an electrically conductive layer at least partially coating said projections, exposing the cells to a cargo to be internalized by the cells, irradiating the substrate surface (and in particular the projections) with one or more laser pulses having a pulse width in a range of about 1 ns to about 1000 ns so as to facilitate uptake of the cargo by at least a portion of the cells (e.g., the cells positioned in the vicinity of the projections (e.g., within hundreds of nanometer (such as less than 100 nm) of the projections)). In some embodiments, the laser pulses have a pulse width in a range of about 10 ns to about 500 ns, e.g., in a range of about 5 ns to about 50 ns.

摘要:
Methods, apparatus, systems, devices, and computer program products directed to enhancements to proximity-based services (ProSe) direct discovery are provided. Among the methods is a method that may be implemented in a proximity services (ProSe) function and that may include receiving a discovery request message including a ProSe application identifier; determining whether or not the ProSe function can retrieve a valid ProSe application code corresponding to the ProSe application identifier; and transmitting a reject-type discovery response message conditioned on the determining that a valid ProSe application code is not available to the ProSe function.
摘要:
System(s), method(s), and device(s) for simultaneous transmission and reception is disclosed here. A wireless transmit receive unit (WTRU) may have multiple antenna panels which may be capable of different modes of operation, such as simultaneous DL/DL (S-DD), simultaneous UL/UL (S-UU) and simultaneous DL/UL (S-DU). Further, the WTRU may use each panel independently to communicate with multiple transmission and receive points simultaneously. The WTRU may accomplish this using transmission control indicators, reference signals, monitoring techniques suitable for multiple transmission and reception point communication.
