Joint resource pools for uplink communications
Examples refer to communication networks between user equipments, UEs, with other devices, such as a base station, BS. Examples refer to communication methods, e.g., for uplink, UL. A joint-resource pool (JRP) is defined.
1. A user equipment, UE, configured to:
receive, from an external device, configuration data of a joint-resource pool, JRP, for uplink, UL, communications in JRP physical resources shared with other UE(s); and
transmit a data in the JRP and, in case of necessity of retransmission, use a particular granted resource for retransmitting the data,
retransmit the data after a backoff timer having expired,
wherein the UE is configured to have a different backoff timer (T 1 ) with respect to the other UEs,
wherein the backoff timer is provided by the external device to the UE with a non-acknowledgement, NACK, message.
2. The UE of claim 1 , configured to:
perform UL communications by transmitting data on granted physical resources.
3. The UE of claim 1 , configured to:
determine whether to perform additional UL communications and, in case of positive determination, perform additional UL communications by transmitting data on JRP physical resources.
4. The UE of claim 1 , wherein the configuration data comprise rules for medium access.
5. The UE of claim 1 , wherein the configuration data comprise rules for collision resolution/avoidance.
6. The UE of claim 1 , wherein the configuration data comprise rules for data retransmissions.
7. The UE of claim 1 , further configured to:
determine whether to perform additional UL communications according to criteria associated to at least traffic or metrics on traffic.
8. The UE of claim 1 , further configured to:
determine whether to perform additional UL communications according to criteria associated to at least quality of service, QoS or metrics on QoS.
9. The UE of claim 1 , further configured to:
determine whether to perform additional UL communications according to criteria associated to at least the determination of an incorrectly transmitted data or metrics on determinations of incorrectly transmitted data.
10. The UE of claim 1 , further configured to:
determine whether to perform additional UL communications according to criteria associated to at least urgency of communications.
11. The UE of claim 1 , further configured to:
determine whether to perform additional UL communications according to criteria associated to at least a selection.
12. The UE of claim 1 , further configured to:
use a particular granted resource for retransmitting a data and use the JRP for transmitting a data scheduled for the particular granted resource.
13. The UE of claim 1 , configured to perform a multi-user access by transmitting the data in the JRP.
14. The UE of claim 1 , further comprising:
a transmission queue implemented at medium access control, MAC, layer and/or physical, PHY, layer,
the UE being configured to evacuate the transmission queue using the JRP and/or the granted resources according to the configuration data.
15. The UE of claim 1 , further configured to:
access the JRP according to a frequency-hopping scheme.
16. The UE of claim 1 , wherein the JRP physical resources are in a combination of any of the time domain, frequency domain, space domain, code domain, and power domain.
17. The UE of claim 1 , wherein the JRP physical resources are in at least time domain.
18. The UE of claim 1 , wherein the JRP physical resources are in at least frequency domain.
19. The UE of claim 1 , wherein the JRP physical resources are in at least code domain.
20. The UE of claim 1 , wherein the JRP physical resources are in at least power domain.
21. The UE of claim 1 , further configured to:
exchange information via D2D or PC5 to align configuration of JRP access.
22. The UE of claim 1 , further configured to:
perform measurements on the utilization of the JRP resources, so as to determine the JRP resources to be used.
23. The UE of claim 1 , wherein:
the JRP and the particular granted resource are Physical Uplink Shared Channel, PUSCH, resources.
24. The UE of claim 1 , wherein the JRP physical resources are in at least spatial domain.
25. The UE of claim 1 , wherein the JRP physical resources are in at least delay domain.
26. The UE of claim 1 , wherein the JRP physical resources are in at least Doppler domain.
27. The UE of claim 1 , wherein information from a sender to a recipient comprises an error or outage probability below a given/selected/predefined level with in a given/selected/predefined time interval.
28. The UE of claim 1 , configured to
achieve the used latency with the maximum allowed probability of failure and/or the maximum reliability/durability of data communication.
29. The UE of claim 1 , further configured to:
perform a communication according to a standard for mobile communications.
30. The UE of claim 1 , configured, in case of reception of a mute signal, to prevent from accessing the JRP for a determined time.
31. A non-transitory digital storage medium having stored thereon a computer program for performing a method comprising:
receiving, by a user equipment, UE, configuration data of a joint-resource pool, JRP, for uplink, UL, communications in JRP physical resources, wherein a JRP physical resource is shared with at least one of other UEs; and
transmitting a data in the JRP and, in case of necessity of retransmission, using a particular granted resource for retransmitting the data after a backoff timer having expired, wherein the backoff timer of the UE is different from the backoff timers of the other UEs, wherein the backoff timer is provided by an external device to the UE with a non-acknowledgement, NACK, message,
when said computer program is run by a computer.
