Resource scheduling in direct device to device communications systems

摘要

Methods, systems, and apparatuses of a wireless communications network can involve transmitting, to a first user equipment (UE), configuration information for the first UE (UE1 configuration information) for an inter-device session (IDS) between the first UE and a second UE. The UE1 configuration information may include a first IDS radio network temporary identifier (IDS-RNTI). A radio resource control (RRC) message indicating a resource allocation can be transmitted to the first UE for the first UE to communicate directly with the second UE.

1. A method performed by a network node of a wireless communications network, the method comprising:
receiving, from a first user equipment (UE), signaling of capabilities that indicate whether the first UE is able to receive inter-device session (IDS) data from a second UE and downlink data from the network node in one subframe; transmitting, to the first UE, configuration information for the first UE (UE1 configuration information) for an IDS between the first UE and the second UE, the UE1 configuration information including a first IDS radio network temporary identifier (IDS-RNTI); transmitting a radio resource control (RRC) message indicating a resource allocation for the first UE to communicate directly with the second UE, the indication of resource allocation including a semi-persistent scheduling (SPS) resource allocation; transmitting a downlink control information (DCI) message to the first UE based on the first IDS-RNTI, wherein an IDS-SPS-RNTI is indicated to the first UE in the RRC message and the DCI that activates the resource allocation is based on an IDS-SPS-RNTI, and the IDS-SPS-RNTI is the same as the IDS-RNTI; and activating the resource allocation using the DCI.
