Problems solved by technology

[0006] Some wireless communication systems may support communication for multiple UEs, which may result in collisions or other interference on resources used by multiple UEs
Furthermore, some UEs may operate according to a half-duplex mode such that the UE may not be able to transmit and receive signals simultaneously due to the effect of interference between incoming and outgoing transmissions

example 1

[0190] Example 1: A method for wireless communication comprising: selecting, by a first wireless device, a first transmission resource to be used for a transmission by the first wireless device and to be included in a In the first set of resource reservation information sent during the transmission interval; through the corresponding second set of resource reservation information, one or more second transmission resources reserved by one or more second wireless devices are determined; and in the sending a signal during a transmission interval, wherein the signal includes the first set of resource reservation information during the first set of resources and the second set of resource reservation information during an additional resource of the transmission interval At least one second resource reservation information set in .

example 2

[0191] Example 2: The method of example 1, further comprising determining a priority associated with reservation of the one or more second transmission resources by the one or more second wireless devices, wherein the The at least one second resource reservation information set of the second resource reservation information sets is identified based at least in part on relative priority.

example 3

[0192] Example 3: The method of any of Examples 1-2, wherein the prioritization is based at least in part on a relationship between the first wireless device and each of the one or more second wireless devices distance between the second wireless device.

Abstract

User equipment (UEs) within a sidelink communications system may employ control forwarding techniques. For example, a UE may piggyback resource reservation information received from other UEs when broadcasting its own resource reservation. A UE that may be in line of sight (LOS) with two other UEs that themselves are in a non-line of sight (NLOS) situation and may include resource reservation information associated with other UEs when broadcasting the control information. For example, when forwarding control information, a UE may identify additional resources available in a transmission interval, and may convey neighbor control information (e.g., known resource reservations of other UEs in the sidelink communications system) using the additional resources. In some cases, the piggybacked resource reservation information associated with the other UEs may be selected based on the amount of additional resources in the transmission interval, a priority of known resource reservation information, etc.

Description

[0001] cross reference [0002] This patent application claims priority to U.S. Patent Application No. 16 / 745,289, filed January 16, 2020, by BHARADWAJ et al., entitled "CONTROL FORWARDING TECHNIQUES FOR WIRELESS COMMUNICATIONS"; U.S. Provisional Patent Application No. 62 / 794,687, filed January 20, 2019, entitled "CONTROLFORWARDING TECHNIQUES FOR WIRELESS COMMUNICATIONS," all of which are assigned to the assignee of the present application. technical field [0003] The following relates generally to wireless communications and, more specifically, to control communication techniques. Background technique [0004] Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems are capable of supporting communication with multiple users by sharing the available system resources (eg, time, frequency, and power). Examples of such multiple-access systems include...
