Abstract: A method includes receiving a first assignment for a first transmission with a first hybrid automatic repeat request (HARQ) process identifier (process ID) in a first network resource, receiving a second assignment for a second transmission with a second HARQ process ID in a second network resource, wherein the first network resource and the second network resource differ in a domain other than a time domain, detecting an indication indicating that the first HARQ process ID and the second HARQ process ID map to a same transmission block (TB), and communicating with an access node, a transmission associated with at least one of the first HARQ process ID or the second HARQ process ID.

Abstract: A system and method for multiplexing traffic. A wireless device such as a user equipment (UE) may receive a first signal over first resources assigned to carry a first downlink transmission from a base station, and receive a first downlink control indication (DCI) message from the base station. The first DCI message may include a pre-emption region (PR) indication and a PR bitmap, and the PR indication may indicate a location of a time-frequency region. The PR bitmap may include bits associated with different portions of the time-frequency region, and each of the bits in the PR bitmap may indicate whether a preemptive downlink transmission is present in the corresponding portion of the time-frequency region.

Abstract: Methods and devices for enhancing the spectral efficiency and/or reliability of uplink transmission without grant are provided. Uplink transmissions without grant are transmitted by UEs or received by base stations in accordance with resource groups that map initial uplink transmissions without grant and non-zero numbers of re-transmissions without grant to sub-regions of a grant-free region of a time-frequency resource.

Abstract: Resources used for downlink communication may be partitioned by the base station so that a portion of the resources is reserved for the downlink transmission of low latency data. However, low latency data may be bursty or sporadic in nature, and may be transmitted in short packets. Therefore, there may not always be low latency data at the base station that needs to be transmitted using all of the low latency resources. System and methods are therefore disclosed in which the base station opportunistically schedules, on the low latency resources, latency tolerant data for one or more latency tolerant UEs. When latency tolerant data is scheduled on the low latency resources, signaling is used to indicate if the latency tolerant transmission on the low latency resources is modified.

Abstract: Systems and methods are provided that facilitate multiple switching points within a slot. A slot format indication is conveyed to a user equipment which indicates which symbols within a slot are uplink, downlink or unknown. Some formats feature half-slot switching meaning that a switch from uplink to downlink transmission takes place twice within a slot. Switching on a more frequent basis can deliver improved latency.

Abstract: Systems and methods are disclosed in which the start time of a downlink transmission to a user equipment (UE) is more flexible. For example, instead of beginning at predetermined starting points in a frame or subframe, a downlink transmission may instead possibly begin every x OFDM symbols, where x may be as small as one OFDM symbol.

Abstract: Systems and methods are provided for transmitting and receiving pre-emption indications. The pre-emption indication is transmitted every K symbols or slots, on a group-common physical downlink control channel. The pre-emption indication is in respect of a group of K symbols or slots preceding a symbol or slot containing the group-common pre-emption indication. The group-common pre-emption indication indicates, for the group of K symbols or slots, which resources are pre-empted. The base station schedules resources for first downlink traffic, and transmits the scheduled first downlink traffic subject to pre-emption, and transmits second downlink traffic by pre-empting resources for the first downlink traffic. On the UE side, the UE receives the pre-emption indication. The UE receives its scheduled traffic taking into account the pre-emption indication.

Abstract: A method includes: a terminal device may determine, based on a type of downlink control information DCI, whether data scheduled by using the DCI exists on a preempted time-frequency resource, to determine whether the data transmitted on the preempted time-frequency resource needs to participate in data decoding.

Abstract: Systems and method for defining sub-bands are provided. Each sub-band has a respective sub-carrier spacing, and at least one sub-band portion. Each sub-band portion has a channelization configuration including a resource block size configuration and a sub-band portion bandwidth. The sub-bands are allocated based on a sub-band configuration framework that includes a preconfigured set of possible sub-carrier spacings, a preconfigured set of possible resource block sizes, and a preconfigured set of possible sub-band portion bandwidths. In some embodiments, to improve bandwidth utilization, the channelization configuration for a given sub-band configures a plurality of resource blocks having a first number of sub-carriers and an additional resource block having a number of sub-carriers other than the first number. A bandwidth portion may include two bandwidth portions having different channelizations with differing numbers of sub-carriers per resource block such that more useful sub-carriers are used than would be possible if only resource blocks having a largest of the differing numbers of sub-carriers were used.
