PROBLEM TO BE SOLVED: To provide methods and apparatus well suited for efficiently communicating small amounts of information relatively frequently in a wireless communications system.SOLUTION: An uplink timing frequency structure for an access point includes a set of dedicated uplink communications resources. Different ones of the set of dedicated uplink communications resources correspond to different individual wireless communications devices currently registered with the access point. In the downlink timing frequency structure for the access point there are dedicated downlink broadcast communications resources. Information received on dedicated uplink air link resources is echoed back or selectively echoed back on the dedicated downlink air link resources. Wireless communications devices monitor downlink dedicated air link resources to recover expression information being communicated by other wireless communications devices in their local vicinity.
Abstract:
Certain aspects of the present disclosure provide techniques and apparatus for determining a modulation and coding scheme (MCS) and channel quality indicator (CQI) for ultra-reliable low latency communications (URLLC). An exemplary method generally includes receiving a channel quality indicator (CQI) from a user equipment (UE) and retrieving parameters from a modulation and coding scheme (MCS) table using the CQI, wherein the table has entries corresponding to different spectral efficiency (SE) values selected to allow the BS to efficiently allocate resources at low SE values to achieve at least a target block error rate (BLER). The method also includes sending a transmission to the UE based on the retrieved parameters.
Abstract:
Fallback procedures for user equipments (UEs) are described that provide efficient fallback to a four-step random access procedure from a two-step random access procedure. For example, after transmitting a first message of a two-step random access procedure, a UE may start a fallback timer or counter and monitor for a second message of the two-step random access procedure for the duration of the fallback timer or counter. At the expiration of the fallback timer or counter, the UE may fall back to a four-step random access procedure. In some cases, the UE may transmit multiple repetitions of the first message and monitor for responses after transmitting the repetitions or after each repetition. Additionally, or alternatively, the base station may transmit an explicit signal to the UE that may signal to the UE to perform a fallback procedure at a beginning or middle of a random access procedure.
Abstract:
A method, a computer program product, and an apparatus are provided. In one configuration, the apparatus transmits a first broadcast signal including information indicating an intention to use a unicast resource for a broadcast. In addition, the apparatus transmits a second broadcast signal in the unicast resource. In another configuration, the apparatus, which is a first wireless device, receives a first broadcast signal from a second wireless device including information indicating an intention to use a unicast resource for a broadcast. In addition, the apparatus receives a first scheduling signal from the second wireless device in a scheduling resource. The first scheduling signal is for indicating a second intention to use the unicast resource for transmitting a second broadcast signal. Furthermore, the apparatus refrains from transmitting a second scheduling signal in the scheduling resource in response to the first scheduling signal.
