摘要:
Methods and apparatus are provided for URLLC and eMBB collision resolution. In one novel aspect, the UE initiates a collision resolution such that an URLLC uplink transmission colliding with the scheduled eMBB UL transmission can be carried out successfully. The UE modifies the scheduled eMBB UL transmission based on the collision resolution. In one embodiment, the URLLC UL transmission is for the same UE and the UE punctures the UL eMBB transmission based on predefined rules and transmitting both the UL URLLC and the UL eMBB. In another embodiment, the URLLC UL transmission colliding with the eMBB is from another UE. In one embodiment, the collision resolution command is embedded in a downlink control information (DCI) specifying a TPC offset larger than 3dB for an HARQ-ACK feedback or for a PUSCH transmission or a stop indicator to stop the UL eMBB transmission through one layer-1 (L1) signaling.

A method and a first network node (800) serving a first cell (800A) in a wireless network, for enabling reduction of interference in a second cell (800B) caused by transmission of reference signals in the first cell (800A). The first network node (800) transmits (8: 1 ) scheduling blocks with said reference signals, using a time offset relative transmission of scheduling blocks in the second cell. A timing advance value is determined (8:3) for a wireless device (802) and the wireless device (802) instructed (8:4) to apply said timing advance value for uplink transmissions. The timing advance value was determined such that uplink symbols transmitted from the wireless device (802) are aligned with uplink symbols received at a second network node (804) of the second cell (804A).

摘要:
A method, an apparatus, and a computer-readable medium for wireless communication are provided. In one aspect, an apparatus is configured to determine an RU allocated to the apparatus within a communication bandwidth for OFDMA transmission. The apparatus is configured to transmit a data packet on the allocated RU based on requirements associated with an amount of inter-RU interference to other RUs allocated to other wireless devices. In an aspect, the requirements may include at least one of an error vector magnitude (EVM) requirement or a spectral mask requirement.
摘要:
A method is shown for allocating a plurality of channels to a plurality of radio nodes (RNs) in a radio access network (RAN). In accordance with the method, an initial RN is selected from among the plurality of RNs. A first of the plurality of channels is assigned to the initial RN. The first channel is selected such that external interference experienced by the initial RN from sources other than the RAN on the first channel is minimized. A second RN is selected from among the plurality of RNs. A second of the plurality of channels is assigned to the second RN. The second channel is selected such that a metric reflective of an information carrying capacity of the RNs that have already been assigned one of the plurality of channels is maximized. The assigned channels are allocated to the respective RNs to which they have been assigned.
摘要:
Systems, methods, and apparatuses for sounding reference signal (SRS) management in carrier aggregation (CA) are described. A user equipment (UE) may be scheduled for overlapping (e.g., concurrent) transmissions of SRS and uplink control or data on different cells of a CA configuration. In some cases, the SRS transmission may be dropped (e.g., the UE may refrain from transmitting a scheduled SRS). While in some cases, the UE may transmit both SRS and another uplink message in overlapping time intervals on different cells (e.g., SRS may be transmitted concurrently with another uplink message). A determination of whether to transmit or drop SRS may be based on whether the different cells have different cyclic prefix (CP) lengths or on whether the SRS is scheduled to be transmitted in a special subframe of a time division duplexing (TDD) configuration, for example.

Techniques for facilitating selective full duplex (FD) operation in one or more UEs are discussed. One example apparatus employable in base stations comprises: receiver circuitry receiving from UEs a FD capability, a self-interference cancellation level, a DL channel metric, and an UL transmit power metric; a processor identifying a subset of the UEs based on the FD capability and determining, for each UE of the subset, whether to implement FD mode, based on the self-interference cancellation level, the quality metric, and the UL transmit power metric; and transmitter circuitry transmitting data to each of the one or more UEs, wherein the transmitter circuitry and the receiver circuitry communicate via the FD mode with each UE of the subset for which the processor determined to implement the FD mode, and communicate via a half-duplex mode with other UEs of the one or more UEs.
