H04L 5/14
H04L 5/00

Abstract:

Various aspects of the present disclosure provide for enabling at least one opportunity to transmit mission critical (MiCr) data and at least one opportunity to receive MiCr data in a time division duplex (TDD) subframe during a single transmission time interval (TTI). The single TTI may be no greater than 500 microseconds. The TDD subframe may be a downlink (DL)-centric TDD subframe or an uplink (UL)-centric TDD subframe. How much of the TDD subframe is configured for the at least one opportunity to transmit the MiCr data and how much of the TDD subframe is configured for the at least one opportunity to receive the MiCr data may be adjusted based on one or more characteristics of the MiCr data. The MiCr data may have a low latency requirement, a high priority requirement, and/or a high reliability requirement. Various other aspects are provided throughout the present disclosure.

Abstract:

Systems and techniques are disclosed for selecting service-specific cells that considers additional information about service availability at the cells. A base station stores service availability information in system information. A UE searching for a service-specific cell on which to camp receives the system information with service availability. The UE analyzes its service requirements against the service availability as well as measured radio conditions and selects a cell that enables service-specific support on which to camp. When a change occurs to availability of the service support at the base station, it notifies the camped UE of the change and the UE obtains the changed system information to determine whether to reselect a different cell on which to camp. When a service-specific cell is not available, the UE may select a suitable cell for normal service and periodically perform cell reselection in an attempt to again camp on a service-specific cell.

Abstract:

Methods, systems, and devices for wireless communications are described. A base station may transmit, and a user equipment (UE) may receive a group physical control channel signaling, which may configure grant uplink transmissions for a set of UEs including the receiving UE. The group physical control channel signaling may indicate allotted resources for configured grant uplink transmissions. The group physical control channel signaling may further indicate a group physical control channel which a UE may monitor for control messages. The UE may transmit a configured grant uplink transmission in accordance with the group physical control channel signaling. The base station may receive the configured grant uplink transmission and may determine a control message which it may transmit in the group physical control channel based on the configured grant uplink transmission. The UE may receive the control message, and may determine whether to retransmit a configured grant uplink transmission based thereon.

H04L 1/00

Abstract:

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a block error rate (BLER) target for communications associated with the user equipment; determine a resource allocation pattern for transmission of channel state information reference signals (CSI-RS) based at least in part on the BLER target; and monitor one or more resources, indicated by the resource allocation pattern, for the CSI-RS. Numerous other aspects are provided.

Abstract:

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine to report first channel state information (CSI), wherein the first CSI is associated with a parameter that indicates a priority of the first CSI. The UE may prioritize the first CSI over a second CSI based at least in part on the parameter. The UE may transmit an indication of the first CSI and may drop the second CSI based at least in part on prioritizing the first CSI over the second CSI. Numerous other aspects are provided.

H04W 72/08

Abstract:

Methods, systems, and devices for wireless communication are described. A wireless communication network may support mission critical (MiCr) communications and mobile broadband (MBB) communications with hybrid multiplexing (e.g., time division multiplexing (TDM) and frequency division multiplexing (FDM)). A base station may identify a first set of resources allocated for MiCr communications and a second set of resources allocated for MBB communications. The first and second set of resources may be multiplexed in the frequency domain, and the base station may transmit MiCr information over the first set of resources under normal data traffic conditions. As data traffic or other conditions associated with MiCr communications change, the base station may schedule MiCr transmissions on the second set of resources allocated for MBB communications, by puncturing the second set of resources for the MiCr communications.

Abstract:

Aspects of the present disclosure relate to wireless communications and, more particularly, to linkage of packet transmissions for ultra-reliable low-latency communications (URLLC) in new radio (NR). A method for wireless communications that may be performed by a user equipment (UE) is provided. The method generally includes receiving a current transmission of a packet; determining, based on the current packet transmission, one or more previous transmissions of the packet occurred and at least one parameter associated with the one or more previous transmissions; and combining the current packet transmission with the previous transmissions based, at least in part, on the determination.

Abstract:

Aspects of the present disclosure provide a scheduling entity for facilitating Multiple Input Multiple Output (MIMO) wireless communication by dynamically assigning ranks to scheduled entities for each sub-band of a slot. In some examples, the rank assigned to a particular scheduled entity may be increased or decreased between sub-bands of the slot based on the amount of scheduled user data traffic for that particular scheduled entity relative to the amount of scheduled user data traffic for other scheduled entities. The scheduling entity further schedules resources within the sub-bands of the slot based on the assigned ranks and transmits an enhanced control channel providing scheduling information indicating the scheduled resources to the scheduled entities.
