Abstract: Various aspects of the disclosure relate to beam information for independent links. For example, beam information for one link may be sent on at least one other link. In some aspects, the independent links may involve a first device (e.g., a user equipment) communicating via different independent links with different devices (e.g., transmit receive points (TRPs) or sets of TRPs). For example, the first device may communicate with a second device (e.g., a TRP) via a first link and communicate with a third device (e.g., a TRP) via a second link. In some scenarios, one link can indicate beam switching for at least one other link. In some scenarios, one link can indicate link recovery for at least one other link. In some scenarios, one link can indicate link failure for at least one other link.

Abstract: A combined symbol constellation may be selected from a uniform symbol constellation that is supported by a de-mapper to provide additional power split options while reducing modifications to the de-mapper. In some examples, a signal may be constructed according to a combined symbol constellation selected from a larger uniform symbol constellation based on a desired power-ratio. The signal may include a base-layer, used to communicate a first set of data, and an enhancement-layer, used to communicate a second set of data, in accordance with the selected combined symbol constellation. The signal may be received and de-mapped according to the combined symbol constellation at a de-mapper that supports a uniform symbol constellation that is larger than the combined symbol constellation.

Abstract: A base station may determine a Doppler metric associated with a wireless channel and a user equipment (UE). The Doppler metric may be determined from received information related to Doppler effects measured by the UE or from directly measured Doppler effects associated with uplink data received from the UE. Based on the determined Doppler metric, the base station may select one or both of a reference signal (RS) density and a channel estimation technique for the wireless channel and associated UE. The base station may transmit an indication of the RS density to the UE. Downlink data bursts and uplink data bursts may include RSs and data according to the indicated RS density. Further, the base station may transmit to the UE, an indication to communicate using the selected wireless channel estimation technique.

Abstract: Methods, systems, and devices for wireless communication are described. Discontinuous reception (DRX) operation may be configured differently on enhanced component carriers (eCCs) than on other component carriers, including a primary cell (PCell). In some cases, a user equipment (UE) may be configured with several different eCC DRX modes. An eCC DRX configuration may, for example, be coordinated with downlink (DL) transmission time interval (TTI) scheduling so each DRX ON duration may correspond to a DL burst duration of the corresponding eCC. The eCC DRX ON durations may also be scheduled according to hybrid automatic repeat request (HARQ) process scheduling. In some examples, eCC DRX ON durations may be based on listen-before-talk (LBT) procedures. In some cases, eCC DRX ON durations may be configured to contain an uplink (UL) burst to enable channel state information (CSI) reporting. The eCC DRX may also be configured to minimize interruption of the PCell.

Abstract: Methods, systems, and devices are described for resource scheduling for different services in a wireless communications system. A base station or a user equipment (UE) operating within a wireless communication system may, for example, communicate using two or more different configurations of resource (e.g., symbol) duration, while maintaining a common tone spacing, bandwidth, transmission time interval (TTI) designation, or the like. For instance, an orthogonal frequency division multiplexing (OFDM) symbol may be subdivided or segmented, and each segment, which may include a cyclic prefix, may be utilized as a resource unit.

Abstract: A wireless communication network uses backhaul negotiation based upon static and dynamic resource assignment on jamming graphs. Static reuse factor design methods including fractional frequency reuse (FFR) are addressed. The jamming graph is used to summarize the interfering relationship between transmitters (nodes in the jamming graph). Negotiation-based algorithm is used to arrive at a static resource assignment so that a large reuse factor can be achieved while jamming scenario can be avoided. As a result of such algorithm, each transmitter is assigned some resources, over which traffic transmission can be done instantaneously to reduce the packet delay for short packets. Based on the result of static resource negotiation algorithm, a dynamic resource algorithm can be run, such that the resources assigned to different nodes can be share in a bursty traffic scenario to further reduce packet delay for larger packet size cases, while jamming be also avoided.

Abstract: Techniques for mitigating interference in a wireless network are described. In an aspect, interference on overhead channels may be mitigated by (i) sending the overhead channels from different base stations in non-overlapping time intervals and (ii) having each interfering base station reduce its transmit power during time intervals in which the overhead channels are sent by neighbor base stations. In one design, a first base station may send an overhead channel in a first time interval, and a second base station may send the overhead channel in a second time interval that is non-overlapping with the first time interval. The base stations may have different frame timing, which may be offset by an integer number of subframes and/or an integer number of symbol periods. Alternatively, the base stations may have the same frame timing, and the first and second time intervals may cover non-overlapping symbol periods with different indices.

Abstract: Methods, systems, and devices for using a common physical downlink control channel (PDCCH) to indicate transmission beams to be used by a base station during a transmission opportunity or a periodicity to monitor search spaces are described. A user equipment (UE) may monitor a search space (in some cases, using a periodicity) for the common PDCCH to determine if transmission beams associated with the UE are to be used during the transmission opportunity. If so, the UE may wake-up during at least a portion of the transmission opportunity to receive additional information. If the common PDCCH indicates that no transmission beams associated with the UE are to be used during the transmission opportunity, the UE may enter or re-enter the sleep state. The UE may switch to a new periodicity for monitoring the search space based on the information transmitted within the common PDCCH.
