Abstract: Embodiments herein relate to a method, performed by a network node (110) in a wireless communication system (100), for handling resource allocations for a first User Equipment, UE (120a) out of a set of UEs (120). Each of the UEs (120) in the set of UEs 5(120) has a different pre-configured frequency allocation for cyclic transmissions, such as cyclic UL and/or DL transmissions. The network node (110) determines, based on a data arrival pattern, such as e.g. a packet arrival time, of the cyclic UL transmissions for each of the UEs in the set of UEs (120), one or more TTIs, where a collision between transmissions to and/or from two UEs (120) out of the set of UEs (120) may occur.

Abstract: A link between a PHY device and a link partner is established by performing link training. If the link becomes at least partially inoperable, a first fast retrain technique is executed. A signature indicating that the first fast retrain technique successfully began but failed during execution before completion of the first fast retrain technique is received at the PHY device. In response to receiving the signature, a second fast retrain technique is executed.

Abstract: Techniques for setting up a communication session responsive to a dedicated bearer failure are described herein. A telecommunications network can implement a server to determine that a user equipment (UE) is incapable of establishing a communication session using a dedicated bearer due to a bandwidth or technology used by the UE. The server can exchange a user plane message with the UE using a default bearer based on determining that the dedicated bearer failed to establish the communication session. The server can establish the communication session for the UE based at least in part on the user plane message associated with the default bearer.

Abstract: Disclosed herein are system, method, and computer program product embodiments for utilizing non-RAM memory to implement a sector emissions model. In some embodiments, a sector-centric testing architecture computes aggregate interference as a sum of contributions from LITE sectors rather than UEs. This granularity enables more accurate modeling of the interference contributions by eliminating sonic of the unrealistic, constraining assumptions about UE emissions originating from the same sector. With a sector-centric architecture, different models can be used to capture intra-sector dynamics based on selected priorities.

Abstract: Methods, systems, and devices for wireless communications are described. To monitor a PDCCH for CA, a UE may receive PDCCH candidates in a plurality of configured component carriers (CCs). In response to a determination that a maximum number of virtual CCs that the UE is capable of monitoring for PDCCH is smaller than a number of the plurality of configured CCs, the UE groups the plurality of configured CCs into CC groups based at least in part on SCS numerologies and PDCCH monitoring configurations corresponding to span patterns within a slot of a DL subframe.
