  • Patent number: 10154528
    Abstract: Handling of related identities may be valuable in communication systems. More particularly, in areas such as long term evolution advanced (LTE-A) proximity services (ProSe), it may be useful to provide for handling of ProSe device to device (D2D) related identities at the radio access network (RAN) level. A method can include deriving an initial layer one identifier corresponding to a target user equipment or group. The method can also include determining whether the initial layer one identifier collides with another layer one identifier corresponding to a different target user equipment or group. The method can further include communicating with the target user equipment or group based on the determination of whether the initial layer one identifier collides with another layer one identifier in use.

  • Publication number: 20180324852
    Abstract: A user equipment (UE) selects first and second radio resources from respective first and second pools of radio resources. In one example these are primarily allocated for contention-free and scheduling-based channel access, respectively. Content to duplicate in parallel communications is selected based at least on a characteristic of uplink data waiting to be sent (such as size) and/or on the selected first and second radio resources (such as timing difference between them). The UE transmits the selected content on each of the selected first and second radio resources. In the examples the content to duplicate was selected from among the uplink data to send and a scheduling request message. In various embodiments one of these transmissions indicates it's a duplicate, and the duplicated scheduling request message is transmitted on the first resource with the uplink data. These teachings are particularly useful for URLLC data.
