Abstract:
Apparatuses, methods and storage media associated with components and implementations of wireless communication networks, and/or portions thereof, are disclosed herein. In embodiments, an apparatus for a next generation NodeB (gNB) may include processing circuitry to determine a number of resource element groups (REGs) to be included in a resource element group bundle (REGB) for a new radio physical downlink control channel (NR-PDCCH), and generate a signal that indicates the number of the REGs. The gNB may further include encoding circuitry, coupled with the processing circuitry, to encode the signal for transmission to a user equipment (UE). Other embodiments may be disclosed throughout.
Abstract:
Described is an apparatus of a User Equipment (UE). The apparatus may comprise a first circuitry, a second circuitry, and a third circuitry. The first circuitry may be operable to determine a Transport Block Size (TBS) of an Uplink (UL) transmission. The second circuitry may be operable to determine a Resource Block (RB) allocation of the UL transmission. The third circuitry may be operable to establish a Modulation and Coding Scheme (MCS) for the UL transmission based upon at least one of the TBS of the UL transmission and the RB allocation of the UL transmission.
Abstract:
Grant-free UL transmissions based on non-orthogonal multiple access (NOMA) may be considered as applicable various use cases including massive connectivity for machine type communication (MTC) and low overhead UL transmission schemes that minimize device power consumption for transmission of small data packets. Described herein are methods, apparatus, and mechanisms are described for MA resource configuration and MA resource selection in the context of grant-free UL transmission. Also described herein are methods and apparatus that incorporate retransmission and HARQ schemes for grant-free UL NOMA transmissions.
Abstract:
Systems and methods of protecting key frames are generally described. A device detects the key frame based on packet inspection of a protocol header or payload field, a payload size, or a message transmitted between protocol layers. The modulation scheme, coding rate or number of maximum retransmissions is dependent on the frame type. The presence of the key frame may be indicated in a DCI that contains parameters that correspond to whether the key frame is to be encoded in a transparent or non-transparent manner, or which protection to use when the key frame is to be transmitted, or in a BSR, a data volume indication or a MAC Control Element. An uplink grant provides increased robustness for transmission of the key frame compared to robustness of an uplink grant for transmission of a normal frame.
Abstract:
An apparatus is configured to be employed within a base station. The apparatus comprises baseband circuitry which includes a radio frequency (RF) interface and one or more processors. The one or more processors are configured to generate control information for loading and interference conditions, generate a control message using the control information for non-orthogonal multiple access (NOMA) or orthogonal multiple access (OMA) uplink transmissions by one or more user equipment (UE) devices, generate a payload data unit (PDU) having the control message, and send the PDU to the RF interface for transmission to the one or more UE devices.
Abstract:
Described is an apparatus of a User Equipment (UE). The apparatus may comprise a first circuitry and a second circuitry. The first circuitry may be operable to define a first set of one or more Extended Narrowbands (ENBs) for Downlink (DL) transmissions spanning a first set of more than six Resource Blocks (RBs) of the system bandwidth. The second circuitry may be operable to define a second set of one or more ENBs for Uplink (UL) transmissions spanning a second set of more than six RBs of the system bandwidth. The apparatus may also comprise a memory to store one or more parameters of the first set of ENBs and one or more parameters of the second set of ENBs.asdf
Abstract:
Non-continuous repetition of physical control and data channels for machine-to-machine communications are described in which information elements are transmitted using blind decoding repetition techniques. Parameters that define the search space for blind decode candidates may define different levels of repetition and time diversity. In some implementations, the repetition decode candidates may be transmitted non-continuously (i.e., discontinuously).
Abstract:
Techniques for providing flexible time-domain resource mapping are provided. Narrowband Internet-of-Things (NB-IoT) user equipment (UE) can be provided with information relating to discontinuous reception of a narrowband physical downlink control channel (NPDCCH) and a corresponding narrowband physical downlink shared channel (NPDSCH). Available subframes for the NPDCCH and the NPDSCH can be provided for the NB-IoT UE or a group of NB-IoT UEs having similar coverage conditions. A flexible time-gap between the NPDCCH and the NPDSCH can also be provided.
Abstract:
Disclosed herein is an apparatus of a user equipment (UE) configured to communicate with an evolved Node B (eNB). The UE may include memory and processing circuitry coupled to the memory. The processing circuitry may be configured to detect a plurality of code blocks received on a Narrowband Physical Broadcast Channel (NB-PBCH) during a Master Information Block transmission time interval (MIB TTI). The processing circuitry may be further configured to partition a code block of the plurality of code blocks into a plurality of subframes. Each of the plurality of subframes includes a bit sequence representing an encoded Narrowband Master Information Block (NB-MIB), and the bit sequence is repeated a number of times within the code block. The bit sequence can be decoded to obtain the NB-MIB.
Abstract:
Embodiments described herein include user equipment (UE), evolved node B (eNB), methods, and systems for narrowband Internet-of-Things (IoT) communications. Some embodiments particularly relate to control channel communications between UE and eNB in narrowband IoT communications. In one embodiment, a UE blind decodes a first control transmission from an evolved node B (eNB) by processing a first physical resource block comprising all subcarriers of the transmission bandwidth and all orthogonal frequency division multiplexed symbols of a first subframe to determine the first control transmission. In various further embodiments, various resource groupings of resource elements are used as part of the control communications.
