Abstract

Claims (25)

1 . A method, comprising:

scheduling, by a user equipment (UE), a periodic data transmission to a second UE on a first resource using at least a first beam and a second beam during a first time period; and

transmitting, by the UE to the second UE, data, through a sidelink between the UE and the second UE, on the first resource using at least the first beam and the second beam during the first time period, wherein the transmitting the data to the second UE on the first resource using at least the first beam and the second beam during the first time period comprises:

transmitting, by the UE, one or more data frames in a Physical Sidelink Shared Channel (PSSCH) to the second UE on the first resource using the first beam during the first time period; and

transmitting, by the UE, the one or more data frames in the PSSCH to the second UE on the first resource using the second beam during the first time period, wherein the first beam has higher beam gain toward the second UE than the second beam, wherein the second beam is an omni-directional beam, and wherein a first beamwidth of the first beam is less than a second beamwidth of the second beam such that the second beam prevents a nearby UE from scheduling sidelink data transmission on the first resource,

wherein during the first time period, for every N consecutive transmissions to the second UE, N 2 transmissions use the second beam and N 1 transmissions use the first beam, N 1 +N 2 =N, and N 2 is less than N 1 , and wherein at least 2N consecutive transmissions occur during the first time period.

2 . The method according to claim 1 , wherein before the scheduling the periodic data transmission, the method further comprises:

measuring, by the UE, channel qualities of a plurality of candidate resources for the periodic data transmission; and

determining, by the UE, the first resource from the plurality of candidate resources, wherein a measured channel quality of the first resource is greater than a first threshold.

3 . The method according to claim 1 , wherein the periodic data transmission is a sidelink data communication.

4 . A method, comprising:

measuring, by a user equipment (UE), channel qualities of a plurality of candidate resources for data communication in a Physical Sidelink Shared Channel (PSSCH) using a first beam, wherein the first beam is an omni-directional beam;

determining, by the UE, a first resource from the plurality of candidate resources, wherein a measured channel quality of the first resource is greater than a first threshold;

scheduling, by the UE, a periodic data transmission to a second UE on the first resource during a first time period; and

transmitting, by the UE to the second UE, data in the PSSCH on the first resource using a second beam during the first time period, wherein a first beamwidth of the first beam is greater than a second beamwidth of the second beam.

5 . The method according to claim 4 , wherein the data communication is a sidelink data communication.

6 . A method, comprising:

measuring, by a user equipment (UE), channel qualities of a first plurality of candidate transmission resources and a second plurality of feedback resources for data communication, wherein each candidate transmission resource in the first plurality of candidate transmission resources corresponds to a different feedback resource in the second plurality of feedback resources;

determining, by the UE, a first resource from the first plurality of candidate transmission resources based on the measured channel qualities of the first plurality of candidate transmission resources and the second plurality of feedback resources; and

transmitting, by the UE, data to a second UE on the first resource.

7 . The method according to claim 6 , wherein the determining the first resource comprises determining at least one of:

that a received signal strength of the first resource is below a first threshold; or

that a received signal strength of a feedback resource corresponding to the first resource is below a second threshold.

8 . The method according to claim 7 , wherein the first resource is a Physical Sidelink Shared Channel (PSSCH), and the feedback resource corresponding to the first resource is a Physical Sidelink Feedback Channel (PSFCH).

9 . The method according to claim 1 , the second beam prevents the nearby UE from scheduling the sidelink data transmission on the first resource while interference from the first beam on the first resource is undetectable by the nearby UE.
