Alternative modulation for a random access message in a two-step random access procedure
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a set of modulations for a random access message associated with a two-step random access channel (RACH) procedure. The set of modulations may be either a first set of modulations or a second set of modulations that is different from the first set of modulations. The set of modulations may be determined based at least in part on whether a signal strength satisfies a signal strength threshold. The UE may transmit the random access message based at least in part on the determined set of modulations. The random access message may include a physical uplink shared channel modulated using the determined set of modulations. Numerous other aspects are provided.
WIRELESS COMMUNICATION APPARATUS AND WIRELESS COMMUNICATION SYSTEM
A wireless communication system includes two wireless communication apparatuses. One of the wireless communication apparatuses wirelessly transmits a signal obtained by up-converting a clock signal. The other of the wireless communication apparatuses generates a clock signal based on a received signal and feeds back a signal obtained by up-converting the generated clock signal to the one wireless communication apparatus. The one wireless communication apparatus generates a clock signal based on the fed-back signal, detects a phase change due to a fluctuation in a transmission path characteristic based on the generated clock signal, and adjusts a phase of a reference clock signal based on the detected phase change.
Transmitting apparatus and signal processing method using removal of transport steam packet header
A transmitting apparatus is provided. The transmitting apparatus includes: a packet generator generating a packet including a header and a payload from an input stream including a plurality of input packets; and a signal processor signal-processing the packet, wherein the header includes a base header which includes: a first field indicating a packet type of the input packets; wherein when the first field is set to a value indicating that the packet type of the input packets is a TS packet, the base header comprises a second field indicating a number of TS packets included in the payload and a third field set to a first value indicating that the header of the packet does not comprises an additional header or a second value indicating that the header of the packet further comprises the additional header, and wherein the third field is set to the second value when TS header compression to remove at least one header of the TS packets is applied to generate the packet.
Method for redefining a time alignment timer of a wireless communication network, corresponding user equipment and network node
Methods and devices for redefining a time alignment timer of a wireless communication network include determining that a Radio Resource Control, RRC, connection from the UE to a network node is operating in Connected Discontinuous Reception, CDRX, mode. In response to determining that the RRC connection is operating in CDRX mode, an initial message include a Protocol Feature Type, PFT, and a User Equipment Type and Software Version Number, UE-TSVN is transmitted, to the network node. In response to the initial message, a handshake message including the PFT, a downlink Protocol Message Type, PMT, indicating a Time Alignment Timer Definition, TATDEF, message type, and a Protocol Message Body, PMB, associated with the TATDEF message type that including one or more values for redefining a time alignment timer is received from the network node.
Crowd sourced location determination
Techniques and systems for determining locations of devices using location data sources are provided. For example, a network device, method, and computer-program product may be provided. In one example, a method may include receiving, on a computing device, a request to locate a device, wherein the request includes an identifier of the device. The method may further include receiving a communication from the device, wherein the communication includes the identifier of the device, and obtaining a location of the device. The method may further include transmitting the location of the device and the identifier of the device to a server, wherein the server is configured to use the location of the device and the identifier of the device to send a response to the requestor of the request.
Methods and apparatus for scheduling resources in radio access networks
The disclosure provides various methods for time-aware scheduling of time-sensitive network (TSN) streams in 5G networks. One method, performed in a core network associated with a radio access network (RAN), is for scheduling resources in the RAN according to a transmission schedule associated with an external network. The method comprises receiving (1210), from the external network, a transmission schedule associated with a time-sensitive data stream and sending (1220), to the RAN, a request to allocate radio resources for communication of the data stream between the RAN and a user equipment (UE). The request further comprises information related to the transmission schedule. The method also comprises receiving (1230), from the RAN, a response indicating whether radio resources can be allocated to meet the transmission schedule associated with the data stream.
CANCELLATION OF DIFFERENT SIDELINK CHANNELS
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a sidelink cancellation indication that indicates a set of resources in which to cancel sidelink communications, wherein the set of resources overlaps with at least one of a physical sidelink feedback channel (PSFCH), a gap symbol, or a sidelink synchronization signal block (S-SSB). The UE may perform one or more sidelink cancellation actions associated with the at least one of the PSFCH, the gap symbol, or the S-SSB. Numerous other aspects are described.
Resynchronization signal transmission in wireless communications
A resynchronization signal (RSS) may extend across multiple physical resource blocks (PRBs) or subframes, which may cause the RRS to be scheduled to overlap with other downlink transmissions. Methods, systems, and devices for wireless communications are described for management of RSS and one or more other transmission types that may have overlapping wireless resources with the RSS. If one or more other downlink transmissions are scheduled for resources that overlap with resources scheduled for an RSS transmission, the UE may receive the RSS transmission or the one or more other downlink transmissions, or a combination thereof, based on a prioritization of the transmission types of the one or more other downlink transmissions relative to RSS. The RSS transmission or the one or more other transmissions may be delayed, dropped, punctured, or rate-matched when the RSS transmission and the one or more other downlink transmissions conflict.
Edge communication networks with edge-located clocks and associated methods
A method for synchronizing a timing end application (TEA) in an edge communication network includes (a) receiving, at a first access device, a time stamp from a first TEA communicatively coupled to the first access device, (b) transmitting the time stamp from the first access device to a second access device via communication media of the edge communication network, (c) adjusting the time stamp to account for transit time of the time stamp from the first access device to the second access device, and (d) after adjusting the time stamp, transmitting the time stamp from the second access device to a second TEA communicatively coupled to the second access device.

A communication system that includes neural network system configured to learn from training examples of radio frequency (RF) signals, and circuitry configured to label a first set of fifth generation (5G) RF signals originated from a first type of source and a second set of 5G RF signals originated from a second type of source. At least one RF impairment is added randomly to each labelled example of the first set of 5G RF signals and the second set of 5G RF signals, wherein randomization of artificially added RF impairment to each labeled example corresponds to addition of different RF impairments randomly to different labeled examples. The neural network system is trained with a plurality of labelled examples. Each labelled example includes an artificially added RF impairment. The circuitry uses the trained neural network system to detect an input 5G RF signal having a new RF impairment.
