摘要： A user equipment can send a notification to a network node indicating that the user equipment is entering a battery saving mode of operation. Reduced physical layer procedures can be implemented based on reduced capabilities indicated by the user equipment. Reduced physical layer procedures can also be implemented based on the network node's reconfiguration of parameters to facilitate the activation of the reduced physical layer procedures. The user equipment can also send to the network node recommendations of reduced physical layer procedures.

摘要： An interference cancelation receiver can cancel channel state information reference signal interference using a single fast fourier transform (FFT), thereby reducing the complexity of the receiver. The transmitter can multiplex a channel state information reference signal (CSI-RS) with a physical downlink shared channel (PDSCH) of another numerology, thereby improving a resource utilization. Thus, significant gains in link and system throughputs can be achieved via the use of the interference cancelation receiver.

摘要： Channel multi-input multi-output (MIMI) systems can be configured with a variable number of codewords where the network an change the number of codewords based on channel conditions, user equipment capability, etc. Thus, the network can efficiently utilize feedback channel overhead while simultaneously improving the capacity of the system. Instead of configuring the UE with a fixed number of codewords for all the channel conditions, the network can change the number of codewords dynamically or semi-statically. The network can determine the number of codewords based on measurements and recommendations from the UE. Alternatively, the network can determine the number of codewords on its own.

摘要： Various embodiments disclosed herein provide for a transmitter that can adjust the size of an information block or segment the information block based on a forward error correction (FEC) code optimum efficiency. Certain FEC codes are more efficient at encoding and decoding longer information blocks and if an information block is shorter than a predetermined length, the transmitter can pad the information block with a group of null bits to lengthen the information block to increase the performance of encoding and decoding the information block. In some embodiments, the transmitter can segment the information block into a set of segments, and if the last segment is below the predetermined length, the transmitter can pad the last segment.

摘要： The described technology is generally directed towards a joint procedure in wireless communications for reporting a partial beam failure or performing beam management when no beams have failed. The joint procedure reports the beam management reference signal received power and control beam recovery on a common feedback channel, which avoids the need for a reserved, dedicated feedback channel resource for beam recovery. Also described is configuring a possibly different failure threshold for each selected beam, whereby the network can configure different beams to have different reliability/quality-of-service levels for example.

摘要： Enhanced beam management for a wireless communication system is provided. In one example, a method comprises: determining, by a device comprising a processor, first beam information for a selected first beam of beams associated with a base station device, wherein the selected first beam is for downlink transmission; determining, by the device, second beam information for a selected second beam of the beams associated with the base station device, wherein the selected second beam is an alternative to the selected first beam for transmission of downlink data to the device, and the determining the second beam information is performed during a random access channel procedure; and transmitting, by the device, to a network device, the first beam information and the second beam information.

摘要： A more efficient 5G network can be achieved by leveraging a centralized radio access network (CRAN) and/or a virtualized radio access network (VRAN) architecture to comply with transport bandwidth requirements for better performance. Additionally, linear compression techniques can be used to reduce the transport bandwidth. Compression on a fronthaul can be achieved by utilizing the concept of spatial compression. After a signal has been compressed, it can be decompressed in accordance with a number of antennas.

摘要： The random access channel procedure for new radio NR can be designed to support multiple use cases with various requirements. The NR physical layer can support the independent configuration of resources used for the random access channel (RACH) procedures that can be transparent to user equipment (UE) devices and independent from resources configured for the UE. For instance, in the case of a standalone NR the RACH configuration can be obtained by the UE by either signaling on the NR carrier or fixed within the telecommunications standard. While in the case of non-standalone NR the RACH configuration can be obtained by the UE by broadcast or dedicated signaling on a different carrier than the NR carrier (e.g. a Long Term Evolution carrier).

摘要： A more efficient mesh network can be achieved by optimizing relay hops between node devices. A number of routes can be determined between node devices of various orders. Furthermore, a number of more efficient routes can be determined between the node devices of various orders. Based on the more efficient routes, relay paths between the node devices can either be maintained or terminated. Accordingly, route metrics can be updated dynamically to reevaluate which routes are more efficient than other routes, thereby optimizing system performance.

摘要： An example method may include a processing system of a base station having a processor assigning at least one resource block of a physical downlink shared channel for a transmission of a channel sounding waveform and transmitting the channel sounding waveform via the at least one resource block. Another example method may include a processing system of a channel sounding receiver receiving from a base station, at a location, a channel sounding waveform via at least one resource block of a physical downlink shared channel, and measuring a channel property at the location based upon the channel sounding waveform that is received.
