Abstract
Physical layer processing and procedures for device-to-device (D2D) discovery signal generation and transmission and scheduling of D2D discovery signals are described. Detection and measurement of a D2D discovery signal, D2D signal identity management, and monitoring by a wireless transmit/receive unit (WTRU) of PDCCH for D2D discovery scheduling is described, as is a WTRU that may be configured with a D2D-specific transmission/reception opportunity pattern. The discovery signal may carry a payload for explicit information about user and/or service identity, and may be mapped to physical resources in such a way as to decouple transmission/reception of the discovery signal from downlink operations. A WTRU may measure a D2D discovery signal quality and report to the network.

Claim
1. A method associated with device to device (D2D) signaling by a wireless transmit/receive device (WTRU), comprising:
selecting a D2D discovery signal schedule indicating allowed subframes to transmit a D2D discovery signal;
determining a scrambling sequence, wherein the scrambling sequence is generated by a scrambling sequence generator, and wherein the scrambling sequence generator is initialized with a pre-configured fixed value at the start of each subframe associated with the D2D discovery signal;
determining to transmit the D2D discovery signal on one or more resource blocks associated with the allowed subframes based on a condition that the one or more resource blocks do not overlap with resources scheduled for a priority channel; and
transmitting the D2D discovery signal using the scrambling sequence, wherein the D2D discovery signal comprises a payload and a guard period, wherein the guard period occupies the last symbol in a sidelink subframe carrying the D2D discovery signal.
2. The method of claim 1, wherein determining the D2D discovery signal schedule comprises receiving a system information block (SIB) from a network and determining the D2D discovery signal schedule based on the SIB.
3. The method of claim 1, wherein determining the D2D discovery signal schedule comprises deriving the D2D discovery signal schedule based on a D2D radio network temporary identifier (D-RNTI) associated with the WTRU.
4. The method of claim 1 comprising:
determining a transmission schedule associated with the priority channel; and
comparing the D2D discovery signal schedule to the transmission schedule associated with the priority channel.
5. The method of claim 4, wherein the priority channel is a Physical Uplink Shared Channel (PUSCH) or a Physical Uplink Control Channel (PUCCH) with ACK/NACK traffic.
6. The method of claim 1, further comprising:
prioritizing a transmission associated with the priority channel over transmission of D2D discovery signal based on a condition that the one or more resource blocks overlap with resources scheduled for the priority channel; and
sending the transmission associated with the priority channel.
7. The method of claim 1, wherein the D2D discovery signal further comprises a reference symbol.
8. The method of claim 7, wherein the reference symbol is in the payload.
9. The method of claim 1, wherein the WTRU is configured to alternate D2D regions when transmitting the D2D discovery signal.
10. The method of claim 1, wherein the WTRU is configured to alternate D2D regions when transmitting the D2D discovery signal using a pre-determined hopping sequence or on a random selection.
11. A wireless transmit/receive device (WTRU) comprising:
a processor configured to at least:
select a device to device (D2D) discovery signal schedule indicating allowed subframes to transmit a D2D discovery signal;
determine a scrambling sequence, wherein the scrambling sequence is generated by a scrambling sequence generator, and wherein the scrambling sequence generator is initialized with a pre-configured fixed value at the start of each subframe associated with the D2D discovery signal;
determine to transmit the D2D discovery signal on one or more resource blocks associated with the allowed subframes based on a condition that the one or more resource blocks do not overlap resources scheduled for a priority channel; and
a transmitter configured to at least:
transmit the D2D discovery signal using the scrambling sequence, wherein the D2D discovery signal comprises a payload and a guard period, wherein the guard period occupies the last symbol in a sidelink subframe carrying the D2D discovery signal.
12. The WTRU of claim 11, wherein the D2D discovery signal schedule is determined by receiving a system information block (SIB) from a network and determining the D2D discovery signal schedule based on the SIB.
13. The WTRU of claim 11, wherein the D2D discovery signal schedule determined by deriving the D2D discovery signal schedule based on a D2D radio network temporary identifier (D-RNTI) associated with the WTRU.
14. The WTRU of claim 11, wherein the processor is configured to at least:
determine a transmission schedule associated with the priority channel; and
compare the D2D discovery signal schedule to the transmission schedule associated with the priority channel.
15. The WTRU of claim 14, wherein the priority channel is a Physical Uplink Shared Channel (PUSCH) or a Physical Uplink Control Channel (PUCCH) with ACK/NACK traffic.
16. The WTRU of claim 11, wherein the processor is configured to:
prioritize a transmission associated with the priority channel over transmission of D2D discovery signal based on a condition that the one or more resource blocks overlap with resources scheduled for the priority channel; and
send the transmission associated with the priority channel.
17. The WTRU of claim 11, wherein the D2D discovery signal further comprises a reference symbol.
18. The WTRU of claim 17, wherein the reference symbol is in the payload.
19. The WTRU of claim 11, wherein the processor is configured to alternate D2D regions when transmitting the D2D discovery signal.
20. The WTRU of claim 11, wherein the processor is configured to alternate D2D regions when transmitting the D2D discovery signal using a pre-determined hopping sequence or on a random selection.
