Abstract
Aspects of the present disclosure provide techniques for configuring device-to-device (D2D) communication in new radio (NR) for one or more user equipments (UEs). Specifically, features of the present disclosure provide techniques for initial beam-pairing for sidelink communication that optimize communication resources (e.g., resource pools) by indicating the direction of traffic (e.g., transmit or receive) during the initial beam-pairing procedure and to establish sidelink communication without the need for scheduling request transmissions between the UEs.
Claims20
A method for wireless communications, comprising:
- initiating, at a first user equipment (UE), an initial beam-pairing procedure to establish sidelink communication with a second UE;
- and
- transmitting a random access signal on resources corresponding to a beam synchronization control signal from the first UE to the second UE, wherein the random access signal includes information to indicate a direction of traffic requested by the first UE that identifies whether the first UE initiating sidelink communication with the second UE is requesting transmission, reception, or both transmission and reception of data from the second UE.
An apparatus for wireless communications, comprising:
- a memory configured to store instructions;
- a processor communicatively coupled with the memory, the processor configured to execute the instructions to:
- initiate, at a first user equipment (UE), an initial beam-pairing procedure to establish sidelink communication with a second UE;
- and
- transmit a random access signal on resources corresponding to a beam synchronization control signal from the first UE to the second UE to allow the second UE to identify a beam from the plurality of beams to establish sidelink communication between the first UE and the second UE, wherein the random access signal includes information to indicate a direction of traffic requested by the first UE that identifies whether the first UE initiating sidelink communication with the second UE is requesting transmission, reception, or both transmission and reception of data from the second UE.
A non-transitory computer readable medium storing instructions, executable by a processor, for wireless communications, comprising instructions for:
- initiating, at a first user equipment (UE), an initial beam-pairing procedure to establish sidelink communication with a second UE;
- and
- transmitting a random access signal on resources corresponding to a beam synchronization control signal from the first UE to the second UE to allow the second UE to identify a beam from the plurality of beams to establish sidelink communication between the first UE and the second UE, wherein the random access signal includes information to indicate a direction of traffic requested by the first UE that identifies whether the first UE initiating sidelink communication with the second UE is requesting transmission, reception, or both transmission and reception of data from the second UE.
An apparatus for wireless communications, comprising:
- means for initiating, at a first user equipment (UE), an initial beam-pairing procedure to establish sidelink communication with a second UE;
- and
- means for transmitting a random access signal on resources corresponding to a beam synchronization control signal from the first UE to the second UE to allow the second UE to identify a beam from the plurality of beams to establish sidelink communication between the first UE and the second UE, wherein the random access signal includes information to indicate a direction of traffic requested by the first UE that identifies whether the first UE initiating sidelink communication with the second UE is requesting transmission, reception, or both transmission and reception of data from the second UE.
