Abstract: Techniques related to reduction of cyclic redundancy check (CRC) overhead in multiple-input-multiple-output (MIMO) transmissions are disclosed. In one example aspect, a method for wireless communication includes determining a transport block for a transmission of data bits, determining multiple layers corresponding to multiple antennas for performing the transmission, and determining a mapping between the transport block and the multiple layers for the transmission. The method also includes selectively omitting a CRC attachment in one or more portions of the transport block in response to a CRC being attached in one portion of the transport block and mapping the transport block to a physical channel for transmission.

Abstract: Methods, devices, and system related to identifying the causes for call drops or call session failures are disclosed. In particular, Radio Frequency (RF) measurements can be included in Session Initiation Protocol (SIP) messages to enable further analysis of the failures. In one example aspect, a method for wireless communication includes determining, by a user device, one or more indicators indicating a channel condition or a signal condition for performing wireless communications. The method also includes transmitting, by the user device, a Session Initiation Protocol (SIP) message to an SIP server indicating a termination of a communication session. The SIP message includes the one or more indicators to enable to SIP server to determine a cause for the termination of the communication session.

Abstract: Methods, devices, and system related to wireless communications are disclosed. In one example aspect, a method for wireless communication includes receiving, by a first access node in a first type of communication network, a request from a wireless device to establish a voice session with an Internet Protocol Multimedia System (IMS); initiating, by the first access node, an IMS voice session establishment for the wireless device; configuring, by the first access node, a Quality of Service (QOS) for the IMS voice session using a Protocol Data Unit (PDU) session modification request; and determining, in part based on one or more capabilities of the wireless device, to refrain from triggering a fallback to a second type of communication network for the IMS voice session establishment.

Abstract: A base station configured to select a time division duplex (TDD) pattern for a user equipment (UE) is described herein. The base station determines a QoS parameter associated with a traffic flow for a UE, selects a TDD pattern for the UE based on the QoS parameter, and configures the UE with the TDD pattern. The base station may select different TDD patterns for the UE based on different QoS parameters associated with different traffic flows of the UE.

Abstract: A computer-implemented method for managing radio spectrum in a cellular network including periodically analyzing a local spectrum utilization data to determine spectrum use levels at the local base station. The method may include periodically receiving, at the local base station, neighbor spectrum utilization data from at least one neighbor base station in the cellular network. The neighbor spectrum utilization data is associated with spectrum use levels at the at least one neighbor base station. The method may include receiving a spectrum assignment request from a mobile computing device and, in response, determining a spectrum assignment for the mobile computing device based on at least one of the neighbor spectrum utilization data and local spectrum utilization data. The method may include transmitting the spectrum assignment to the mobile computing device.

Abstract: Methods, devices, and system related to adaptive determination of payload sizes based on usage patterns of the contents are disclosed. In one example aspect, an apparatus for wireless communication includes a processor that is configured to transmit a first data packet associated with a first network content to a user device, receive a request from the user device indicating a switch to a second network content from the first network content, determine a usage pattern associated with the first network content based on information included in at least the first data packet and the request, and adaptively change, based on the usage pattern, a payload size of a second data packet associated with a subsequent transmission of the first network content.

Abstract: Systems may comprise a connectivity manager application operating on a User Equipment (UE) for optimal and secure performance of local applications and improving user experience by optimizing application performance (e.g., detecting data stall events). The systems may monitor incoming internet protocol (IP) packets for one or more applications operating on the UE. The connectivity manager application may detect a drop in a rate at which the IP packets are received over a period of time and determine to reregister and/or reattach to a different node within a network or at a new network.

Abstract: Techniques for setting up a communication session associated with Evolved Packet System Fallback (EPSFB) are described herein. A fifth generation telecommunications network can implement a server to determine that a user equipment (UE) is incapable of establishing a Voice over New Radio (VoNR) call due to a chipset or other technology used by the UE. The server can send a message (e.g., a SIP380 Alternative Service message) to the UE to cause the UE to begin fallback to another network without waiting for an instruction from a base station in a standardized call flow. The server can establish the communication session for the UE using fewer call flow steps than a number of steps used by a standardized call flow.

Abstract: Dynamically steering data traffic sessions based on traffic type may include: determining that both frequency division duplex (FDD) and time division duplex (TDD) are available for an air interface between a user equipment (UE) and a base station (BS); determining a first traffic type expected over the air interface for a first data traffic session; based on at least the first traffic type, determining that FDD is a preferred duplex scheme for the first data traffic session; instructing the UE to use FDD over the air interface for the first data traffic session; determining a second traffic type expected over the air interface for a second data traffic session; based on at least the second traffic type, determining that TDD is a preferred duplex scheme for the second data traffic session; and instructing the UE to use TDD over the air interface for the second data traffic session.
