Abstract

The disclosure relates in some aspects to sharing wireless communication resources. For example, a first type of device allocated to use a first resource pool may dynamically use a second resource pool allocated for a second type of device. The first type of device may use an entry criteria to determine whether to use the second resource pool. In some aspects, the entry criteria may specify that resource sharing is permitted if a ratio of resources used by devices of the second type (relative to the total resources in the second resource pool) is less than a threshold. In addition, the first type of device may use an exit criteria to determine whether to stop using the second resource pool. In some aspects, the exit criteria may specify that resource sharing should stop if a ratio of resources used by devices of the second type is greater than a threshold.

Claims20

Dependent claims

A method of communication for an apparatus, comprising:

receiving, from at least one first device, at least one scheduling assignment (SA) for a device-to-device communication resource pool allocated for a first radio access technology (RAT);
determining, based on the at least one SA, an indication of use of the resource pool, wherein the determination of the indication comprises identifying, based on the at least one SA, at least one first resource of the resource pool that is used by the at least one first device for first communication using the first RAT;
comparing the indication to a threshold;
determining, based on the comparison, to use the resource pool for communication by the apparatus using the second RAT;
identifying a set of candidate resources from the resource pool for the communication by the apparatus using the second RAT, wherein the set of candidate resources excludes the at least one first resource of the resource pool that is used by the at least one first device for the first communication using the first RAT;
using a listen-before-talk (LBT) operation to reserve at least one second resource of the set of candidate resources, wherein the at least one second resource excludes at least one third resource of the set of candidate resources identified by the LBT operation as being used by at least one second device for second communication using a second RAT;
and
communicating data via the at least one second resource using the second RAT.

An apparatus for communication comprising:

a memory;
and
a processor coupled to the memory,
the processor and the memory configured to:
receive, from at least one first device, at least one scheduling assignment (SA) for a device-to-device communication resource pool allocated for a first radio access technology (RAT);
determine, based on the at least one SA, an indication of use of the resource pool, wherein the determination of the indication comprises identifying, based on the at least one SA, at least one first resource of the resource pool that is used by the at least one first device for first communication using the first RAT;
compare the indication to a threshold;
determine, based on the comparison, to use the resource pool for communication by the apparatus using the second RAT;
identify a set of candidate resources from the resource pool for the communication by the apparatus using the second RAT, wherein the set of candidate resources excludes the at least one first resource of the resource pool that is used by the at least one first device for the first communication using the first RAT;
use a listen-before-talk operation to reserve at least one second resource of the set of candidate resources, wherein the at least one second resource excludes at least one third resource of the set of candidate resources identified by the LBT operation as being used by at least one second device for second communication using a second RAT;
and
communicate data via the at least one second resource using the second RAT.
