Abstract: Various radio resource management techniques may be implemented to reduce in-device coexistence issues and/or interference between a Uu link established between a mobile device (first UE) and a base station (first NB), and a sidelink/PC5 link established between the first UE and another mobile device (second UE), where the second UE is served by a different base station (second NB). The first UE may receive, from the first NB, measurement configuration information that enables/configures the first UE to report to the NB any indication(s) of issues caused by communications between the first UE and the second UE over the PC5 link affecting communications between the first UE and the first NB over the Uu link, and/or communications over the Uu link affecting communications over the PC5 link. The first NB may analyze the feedback from the first UE and may implement mitigation measures to reduce/eliminate any interference and/or in-device-coexistence issues.

Abstract: This disclosure relates to techniques for handling voice and data under uplink limited conditions in a wireless communication system. A wireless device and a base station may establish a wireless communication link. Transmission time interval bundling (TTI-B) may be enabled for uplink communications between the wireless device and the base station. It may be determined that the wireless device is experiencing uplink limited conditions. One or more rules prioritizing a first type of data over a second type of data for uplink communications may be enabled based on TTI-B being enabled and the wireless device experiencing uplink limited conditions.

Abstract: Described is a user equipment (UE) that is connected to a network component, the user equipment and the network component configured with a carrier aggregation functionality. The UE performs a method that includes determining a primary component carrier and at least one secondary component carrier associated with the carrier aggregation functionality of the user equipment, determining a component carrier quality measurement (CQM) metric for each of the component carriers, when an uplink data packet is capable of being transmitted over the secondary component carrier, selecting one of the primary component carrier and the at least one secondary component carrier based on the CQM metrics, generating measurement data indicative of the selected component carrier to increase a probability to transmit the uplink data packet over the selected component carrier and transmitting the measurement data to the network component.

Abstract: This disclosure relates to techniques for a wireless device to report uncategorized data in a buffer status report. A first portion of buffered uplink data to be reported in a buffer status report may be categorized using a traffic flow template. A second portion of buffered uplink data to be reported in the buffer status report may not be categorized using the traffic flow template. A buffer status report indicating both the categorized and the uncategorized buffered uplink data may be transmitted to a base station providing a serving cell to the wireless device. According to some embodiments, the categorized buffered uplink data may be stored in a baseband processor buffer of the wireless device, while the uncategorized buffered uplink data may be stored in an application processor buffer of the wireless device.

Abstract: A wireless communication system is presented in which user equipment (UE) performs non-intra-frequency (NIF) cell reselection. The NIF cell reselection process can: detect, on a discontinues reception (DRX) cycle, whether a NIF for a second cell has passed a second reselection threshold; perform, on the DRX cycle, additional checks or measurements to determine whether a higher priority NIF for a third cell has passed a third reselection threshold; and continue a cell reselection process for the second cell and the third cell. The NIF cell reselection techniques can help ensure that the UE reselects to higher priority cells without expending an unnecessary amount power.

Abstract: Apparatus, system and methods for evaluating link quality within a cellular system. A user equipment (“UE”) is connected to a network, wherein the UE communicates data to the network on an uplink (“UL”) link. The UE determines a requested buffer size for a UL communication, determines a transport block size for the UL communication based on a primary set of allocation parameters, and compares the requested buffer size to the transport block size to determine if a data rate for the UL communication satisfies a threshold. When the data rate satisfies the threshold, the UE identifies the UL link as a good quality link and sends acceptable link quality feedback to the network. When the data rate does not satisfy the threshold, the UE performs a further action to test a quality of the UL link.

Abstract: A connection with a network that includes a base station (BS) may be established by a user device (UE) via a wireless connection, for conducting communications using semi persistent scheduling (SPS) in a connected discontinuous reception (C-DRX) mode. The SPS transmit periodicity may be adjusted with respect to the SPS activation command and the SPS interval UL (for uplink). Data may then be transmitted during the C-DRX On-Duration periods according to the determined SPS transmit periodicity. In some embodiments, the SPS transmit periodicity is adjusted such that following a first C-DRX On-Duration period when an SPS activation command is received, SPS data transmission occurs a specified number of subframes earlier during each subsequent C-DRX On-Duration period than in the first C-DRX On-Duration period. The SPS data transmission in each subsequent C-DRX On-Duration period may take place as soon as the UE device wakes up during the On-Duration period.

Abstract: Methods that are performed by a user equipment (UE) and corresponding methods of base stations that allow a UE to determine whether the UE is in a carrier aggregation enabled or disabled state. One exemplary embodiment of a method performed by a UE determines a first artificial value for a first parameter and a second artificial value for a power headroom (PHR) for a secondary component carrier (SCC), the first and second artificial values being substantially low relative to a configuration of the network, generates an artificial report including the first and second artificial values, transmits the artificial report to a primary cell providing a primary component carrier (PCC) and receives an indication that the UE is placed in a carrier aggregation disabled state.
