Problems solved by technology

[0011] Other unilateral actions on the part of the UE, such as simply stopping uplink communication without coordinating the eNB, may lead to power loop failure at the eNB
Other issues that exist in legacy LTE include the usual lack of ability on the part of the UE to suggest desired configurations as alternatives to configurations with coexistence issues
For at least these reasons, the uplink coexistence problem at the UE may remain unresolved for a long time, reducing the performance and efficiency of the UE's other radios

Embodiment Construction

[0029] Aspects of the present disclosure provide techniques for alleviating coexistence issues in multi-radio devices. As stated above, some coexistence issues persist because the eNB is unaware of the interference encountered by other radios at the UE side. According to one aspect, the UE identifies existing or potential coexistence issues and sends a message to the eNB indicating that there is a coexistence issue. The message may include: identification of resources experiencing coexistence problems, identification of resources experiencing few (or no) coexistence problems, indication that some LTE events were rejected by arbitration at the UE, modified Channel Quality Indicator (CQI ), a modified Power Headroom Report (PHR), or any other helpful information. The eNB then knows that there is a coexistence problem at the UE and can select and implement mechanisms to assist the UE in mitigating the coexistence problem. Examples are described in more detail below.

Abstract

A method of wireless communication includes receiving signaling from a served User Equipment (UE), via a radio access technology, indicating an interfering technology associated with coexistence issues experienced by the served UE. The method also includes calculating future subframes expected to experience coexistence issues based on previous subframes estimated to have experienced coexistence issues.
