Embodiment Construction

[0042] Some wireless communication systems may send control information to UEs using a set of control resources within the system bandwidth. In some examples, control information may not span the entire system bandwidth, and may instead be sent in certain sets of control resources including common control information or UE-specific control information. Accordingly, UEs within the system may monitor decoding candidates of a common search space for control information intended for multiple UEs, and may monitor decoding candidates of a UE-specific search space for control information designated for a UE. As described herein, a base station may map UE-specific control information to a set of control resources otherwise associated with common control information (ie, a common set of control resources). Such a mapping may improve scheduling flexibility on systems employing separate sets of common and UE-specific control resources.

Abstract

User equipment (UE)-specific information may be transmitted within a control resource set configured to carry resources common to UEs within a system. The UE-specific information may be associated with a search space having an aggregation level different from aggregation levels used with the common control resources and may occupy different modulation symbols within the common control resource set(e.g., to support flexible scheduling for multiple UEs). A base station and UE may operate in a system using one or more control resource sets within a system bandwidth. The UE may detect common control resources by monitoring decoding candidates in the control resource set according to a first set of aggregation levels. The UE may detect UE-specific control resources by monitoring decoding candidates in the control resource set according to other aggregation levels. The UE and base station may communicate based on control information obtained from the monitoring.

Description

[0001] cross reference [0002] This patent application claims U.S. Patent Application No. 15 / 694,143, filed September 1, 2017, by John Wilson et al., entitled "Common Control Resource Set With User Equipment-Specific Resources," and filed by John Wilson et al., 2016 Priority to U.S. Provisional Patent Application No. 62 / 437,966, filed December 22, 1999, entitled "Common Control Resource Set With User Equipment-Specific Resources," each of which is assigned to the assignee of the present application people. Background technique [0003] The following relates generally to wireless communications, and more specifically to a set of common control resources including user equipment specific resources. [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 may be multiple-access systems capable of supporting communication with multiple users by ...
