Abstract: According to an aspect, a wireless device is configured to transmit control data for transmission in a short physical uplink control channel, sPUCCH, that can carry only 24 coded bits. The wireless device codes 11 bits of the control data into 12 encoded bits using a 12-row Reed-Muller generator matrix having full rank and transmits the 12 encoded bits in the SPUCCH. According to another aspect, a wireless device is configured to transmit control data for transmission in an sPUCCH that can carry only 24 coded bits per resource block allocated to the sPUCCH transmission. The wireless device determines that there are 21 or 22 bits of control data to be encoded for transmission in the sPUCCH and allocates at least 2 resource blocks to the sPUCCH transmission. 22 of 22

Abstract: Aspects of the present disclosure provide adaptive radio link monitoring for machine type communication(s) (MTC), enhanced MTC (eMTC), and/or narrowband Internet-of-Things (NB-IoT). In one aspect, a method is provided which may be performed by a user equipment (UE). The method generally includes receiving a first configuration of parameters for receiving downlink control channel signaling, the first configuration of parameters associated with a first coverage level; measuring at least one parameter related to channel conditions; determining one or more dynamic radio link monitoring (RLM) threshold values for the at least one parameter based, at least in part, on the first configuration of parameters; and performing RLM functions based on the one or more dynamic RLM threshold values. The threshold may comprise early out thresholds that occur before out-of-sync (OOS) or in-sync thresholds. The thresholds may be determined using lookup tables.

Abstract: Coverage enhancement (CE) levels by Machine Type Communication (MTC) devices may identify a first bundling level indicating a number of redundant versions of information to be transmitted to a receiver in a control channel transmission. The CE levels may also identify a second bundling level indicating a number of redundant versions of information to be transmitted to the receiver in a shared channel transmission. The CE levels may also set an indicator in a control information field to indicate the second bundling level based on the first bundling level and the second bundling level.

Abstract: Decoding of a first message is disclosed, wherein first and second messages arc encoded by a code (represented by a state machine) to produce first and second code words, which arc received over a communication channel. A plurality of differences ( each corresponding to a hypothesized value of a part of the first message) between the first and second messages are hypothesized. An initial code word segment is selected having, as associated previous states, a plurality of initial states (each associated with a hypothesized difference and uniquely defined by the hypothesized value of the part of the first message). The first message is decoded by (for each code word segment, starting with the initial code word segment): combining the code word segment of the first code word with a transformed (based on the hypothesized difference of the initial state associated with the previous state of the state transition corresponding to a first message segment content) code word segment of the second code word to produce a combined code word segment, determining a decision metric associated with a probability that the combined code word segment corresponds to the first message segment content, and selecting (for the first message) the first message segment content or a second message segment content based on the decision metric. If the first message segment content is selected, the subsequent state of the state transition corresponding to the first message segment content is associated with the initial state associated with the previous state of the state transition.

Abstract: A STA may perform packet detection to detect a packet and decode a legacy preamble of the detected packet including a legacy short training field (L-STF), a legacy long training field (L-LTF), and a legacy signal (L-SIG) field. The STA may decode a high efficiency signal A (HE-SIG-A) field to obtain a first partial association identifier (PAID) comprising group information. If the decoded group information matches group information stored in a memory of the STA, the STA may decode a high efficiency (HE) preamble and a high efficiency signal B (HE-SIG-B) field of the detected packet. The HE-SIG-B field may include a station identifier within the group. When the group information is combined with the station identifier, the STA may determine an accurate address.
