Abstract
Aspects of the disclosure pertain to systems and methods for multiplexing of low latency and latency tolerant communications. When low latency traffic pre-empts latency tolerant traffic in a first interval, the pre-empted low latency traffic can be transmitted in a subsequent interval. There are multiple designs disclosed for notifying UE that are affected by the pre-emption events. The various designs include implicit or explicit notification that can be semi-static or dynamic. Examples of the notification include notification of that a pre-emption event occurs, notification of the location of the pre-emption event, notification of whether a supplementary transmission will occur and notification of the location of the supplementary transmission.
Claims21
A method for notifying a UE of pre-emption of a portion of resources during a first interval, the method comprising:
- transmitting an indication of granularity of one or more resources within the first interval via higher layer signaling, the granularity in both time and frequency domains of the one or more resources within the first interval being configurable;
- scrambling at least part of an indication of pre-emption of the portion of resources during the first interval using a radio network temporary identifier (RNTI), the indication of pre-emption including bits that identify the one or more resources within the first interval that are preempted;
- and
- transmitting the indication of pre-emption, including the scrambled part, to the UE in a downlink control information (DCI) message over a physical downlink control channel (PDCCH).
A method for notifying a UE of pre-emption of a portion of resources in a first interval, the method comprising:
- receiving an indication of granularity of the portion of resources via higher layer signaling, the granularity in both time and frequency domains of the portion of resources being configurable;
- receiving, over a physical downlink control channel (PDCCH), a downlink control (DCI) message containing an indication of pre-emption of the portion of resources in the first interval, at least part of the indication of pre-emption being scrambled;
- and
- using a radio network temporary identifier (RNTI) to descramble the scrambled part of the indication of pre-emption, the indication of pre-emption including bits that identify one or more resources within the first interval that are preempted.
An apparatus comprising;
- a processor;
- a computer-readable media having stored thereon processor-executable instructions, that when executed by the processor, cause the apparatus to:
- transmit an indication of granularity of one or more resources within the first interval via higher layer signaling, the granularity in both time and frequency domains of the one or more resources within the first interval being configurable;
- scramble at least part of an indication of pre-emption of a portion of resources during a first interval using a radio network temporary identifier (RNTI), the indication of pre-emption including bits that identify the one or more resources within the first interval that are preempted;
- and
- transmit the indication of pre-emption, including the scrambled part, to the UE in a downlink control information (DCI) message over a physical downlink control channel (PDCCH).
An apparatus comprising:
- at least one antenna;
- a processor;
- a computer-readable media having stored thereon processor-executable instructions, that when executed by the processor, cause the apparatus to:
- receive an indication of granularity of a portion of resources via higher layer signaling, the granularity in both time and frequency domains of the portion of resources being configurable;
- receive, over a physical downlink control channel (PDCCH), a downlink control (DCI) message containing an indication of pre-emption of the portion of resources during a first interval, at least part of the indication of pre-emption being scrambled;
- and
- use a radio network temporary identifier (RNTI) to descramble the scrambled part of the indication of pre-emption, the indication of pre-emption including bits that identify one or more resources within the first interval that are preempted.
