Method and apparatus for low latency transmissions
A resource assignment can be received. A first set of time-frequency resources in a subframe can be determined from the resource assignment. A second set of time-frequency resources in the subframe can be determined. The second set of time-frequency resources can be used for a second latency data transmission. The second set of time-frequency resources can overlap with at least a portion of the first set of time-frequency resources. A first latency data transmission in the subframe can be decoded based on the determined first and second set of time-frequency resources. The first latency transmission can have a longer latency than the second latency transmission.
Method for assigning identifiers to fronthaul traffic flows in O-RAN compliant radio access network
A method of enabling enhanced Management Plane functions on the fronthaul interface between Open Radio Access Network Radio Unit (O-RU) and O-RAN Distributed Unit (O-DU) includes: identifying four subfields within 16-bit Extended Antenna Carrier Id (Eaxc-ID) field using a first set of four specified bitmasks including DU_Port_ID bitmask, BandSector_ID bitmask, CC_ID bitmask, and RU_Port_ID bitmask; and providing a second set of specified bitmasks including at least one of band-bitmask, sector-bitmask, channel-type-bitmask, and layer-antenna-port-bitmask, wherein: i) band bitmask defines which bits within the BandSector_ID bitmask subfield are used to indicate band; ii) sector bitmask defines which bits within the BandSector_ID bitmask subfield are used to indicate sector-id; iii) channel-type bitmask defines which bits within the RU_Port_ID bitmask subfield are used to indicate channel type; and iv) layer-antenna-port bitmask defines which bits within the RU_Port_ID bitmask subfield are used to indicate one of antenna port number or data layer number.
Uplink control information transmission on autonomous uplink in new radio-unlicensed (NR-U)
Wireless communications systems and methods related to communicating uplink control information (UCI) in a network operating over multiple aggregated unlicensed carriers are provided. A first wireless communication device communicates, with a second wireless communication device, a downlink communication signal. The first wireless communication device communicates, with the second wireless communication device, an unscheduled uplink communication signal including an uplink report associated with the downlink communication signal, the unscheduled uplink communication signal communicated based on a listen-before-talk (LBT) procedure. The uplink report includes at least one of an acknowledgement (ACK) for data in the downlink communication signal, a negative-acknowledgement (NACK) for the data in the downlink communication signal, or channel information based at least on the downlink communication signal.
Uplink control information transmission
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of an offset value from a first modulation and coding scheme relating to a first code rate for a payload data transmission. The UE may determine, for a transmission of uplink control information, a second modulation and coding scheme, relating to a second code rate, that is different from the first modulation and coding scheme based at least in part on the offset value. The UE may transmit the uplink control information using the second modulation and coding scheme based at least in part on determining the second modulation and coding scheme. In some aspects, a UE may segment uplink control information. Numerous other aspects are provided.
Mixed numerology OFDM design
Methods, systems, and devices are described for hierarchical communications and low latency support within a wireless communications system. An eNB and/or a UE may be configured to operate within the wireless communications system which is at least partially defined through a first layer with first layer transmissions having a first subframe type and a second layer with second layer transmissions having a second subframe type. The first subframe type may have a first round trip time (RTT) between transmission and acknowledgment of receipt of the transmission, and the second layer may have a second RTT that is less than the first RTT. Subframes of the first subframe type may be multiplexed with subframes of the second subframe type, such as through time division multiplexing. In some examples symbols of different duration may be multiplexed such that they different symbol durations coexist.
Channel state information configuration and reporting for ultra reliable low latency communication
The present disclosure provides techniques configuring channel state information (CSI) reporting for certain service types, such as the ultra-reliable low latency communications (URLLC) service type. In some cases, a UE may obtain information regarding a first set of channel state information (CSI) reporting configurations for a first service type separate from a second set of CSI reporting configurations for a second service type, receive a first downlink control information (DCI) scheduling a CSI report for the first service type on at least one physical uplink shared channel (PUSCH), generate at least one CSI report for the first service type based on one of the first set of CSI reporting configurations selected based on a field in the DCI, and transmitting the CSI report for the first service type on the PUSCH.
