  • the term “User Equipment (UE)” refers to a computing device capable of wireless digital communication such as a smart phone, a tablet computing device, a laptop computer, a multimedia device such as a television or gaming system, or other type computing device that is configured to provides text, voice, data, or other types of digital communication over wireless communication.

  • MCS modulation and coding schemes
  • An MCS includes both a modulation type and a coding scheme.
  • Example modulation types include, but are not limited to, different levels of quadrature amplitude modulation (QAM), such as 8QAM, 16QAM, 64QAM, 128QAM, 256QAM, and so forth.
  • QAM quadrature amplitude modulation
  • Different types of coding schemes can be used, from efficient coding schemes to robust coding schemes. When there is a higher SNR between a UE and a base station, higher MCS levels (with a higher QAM and/or more efficient coding scheme) can be used to increase the spectral efficiency of the transmission, measured in bits per second per hertz.
  • each modulation level multiple different coding schemes can be included. Coding schemes can be used to recover from transmission errors. More robust coding schemes can recover from higher bit error rates, while reducing the overall transmission throughput. Conversely, more efficient coding schemes can allow for higher transmission throughput, while reducing the ability to recover from transmission errors. With relatively high SNRs, it is possible to use both high modulation levels (i.e. 16QAM, 64QAM) and efficient coding schemes. As the SNR decreases, more robust coding schemes can be used, until the SNR decreases to a point where a lower modulation level (i.e. QAM, BPSK) can be used to increase the spectral efficiency.
  • a lower modulation level i.e. QAM, BPSK
  • a table can be used to identify specific coding schemes and modulation levels that can be used for a specific SNR range.
  • the table can also include other information, as discussed in the proceeding paragraphs.
  • UL transmissions typically have a lower SNR than DL transmissions, since transmission power from the UE is limited. However, in certain instances a UE may only transmit a short distance to a base station in a relatively noise free environment. For example, when a low power base station is located in a same room or same building as a UE, it can be possible for the UE to transmit an UL signal with a relatively high SNR.
  • the use of an increased MCS can take advantage of the relatively high SNR to increase the spectral efficiency of the UL transmission, thereby enabling higher UL transmission rates by the UE.
  • the increased spectral efficiency may reduce the amount of power used to transmit each bit.
  • Equipment and an eNB can include an UpLink (UL) Modulation Coding Scheme (MCS) table covering the SNR operational range of a 256-order Quadrature Amplitude
  • UL UpLink
  • MCS Modulation Coding Scheme
  • signaling methods can support independent DL and UL table configurations per Control Channel (CC), or per CC per UL subframe set, or per antenna ports, in accordance with flexible 256QAM capability reporting of a UE.
  • Level one (LI) signaling schemes can support fallback operation to ensure a robust connection between the eNB and the UE.
  • subframe-set-dependent MCS table configurations can improve the throughput performance, which may be applied when more than one UL subframe set is configured for a given UE.
  • MCS-table specific resources can be determined for Uplink Control Information (UCI) on Physical Uplink Shared Channels (PUSCH).
  • MCS-table-specific power control offset parameters can be provided for PUSCH transmissions.
  • FIG. 1 depicts a wireless system, in accordance with an example.

  • the eNB 210 can encode a first signaling message 230 including UL MCS table information for transmission to the UE 210 in response to a 256QAM coding scheme indicator.
  • the first signaling message 230 may include an MCS table configuration message.
  • the UE 210 can decode the first signaling message 230 including the UL MCS information received from the eNB 205.
  • the UE 210 can determine an UL MCS table for a 256QAM coding scheme 235 from a plurality of MCS tables based on the UL MCS information.

  • the 256QAM MCS table can be independently configured in DL and UL for a given UE. It is to be noted that when two UL subframe sets are configured by a higher layer, the UL 256QAM MCS table can be configured for both two subframe sets, or applied to one subframe set as illustrated in the following exemplary code:
  • altULMCS-Table indicates the applicability of the alternative UL MCS table (i.e. UL 256QAM MCS table) for the concerned cell.
  • the value allSubframes indicates the alternative UL MCS table applies to the subframes, if configured, a UL-SubframeSetl indicates the alternative UL MCS table applies to UL subframe setl, and value UL- SubframeSet2 indicated the alternative UL MCS table applies to UL subframe set2. If this field is not present, the UE shall use the legacy UL MCS table for all subframes, if configured.
  • one MCS table can be configured individually for each serving cell, and/or per UL subframe set or per UL power control loop, and/or per antenna port or MIMO layer. The latter option is motivated by the fact that the UE may implement different RF power amplifiers with different maximum transmission power for different antenna.
  • the DL MCS table and the UL MCS table can be jointly configured by one IE assuming a similar SINR status occurs at a receiver side for both DL and UL.
  • the legacy DL/UL MCS table supporting 6-orders of modulation can be configured for a serving cell if a corresponding IE was set to a predefined value or not present.
  • the UE assumes the 256QAM MCS table can be applied in both DL and UL for PDSCH and PUSCH scheduled by DCI format with CRC scrambled by C-RNTI. Otherwise, the UE can assume the legacy MCS tables are used for data transmission and reception.
  • the UE 210 can receive a DCI format (e.g., DCI format

  • One bit in the DCI format may indicate the UL MCS table. In one example, the value "0" is used to indicate the legacy UL MCS table, and the value "1" is used to indicate the UL 256QAM MCS table.
  • the legacy UL MCS table can be selected for PUSCH if the associated DCI format 0 or 4 is transmitted in Common Search Space (CSS) and the UL 256QAM MCS table can be used for PUSCH if the associated DCI format 0 or 4 is transmitted in UE-specific Search Space (USS).
  • a UE may determine the selected UL MCS table based on the physical channels used to convey the DCI format 0 or 4. For example, the UE can use the legacy UL MCS table if it is conveyed in the first EPDCCH resource set. The UE can use the UL 256QAM MCS table if the corresponding DCI format is conveyed in the second EPDCCH resource set. A combination of these alternative schemes may also be utilized.
  • the UL MCS table can be indicated by the sequence used to scramble the CRC bits of UL DCI formats.
  • the CRC bits of DCI formats, used for UL grant, are scrambled with a selected sequence according to the intended MCS table.
  • the UL MCS table can be indicated by different C- RNTI values.
  • the legacy UL MCS table can be used if the CRC bits of a DCI format are scrambled with a first C-RNTI value and the UL 256QAM MCS table can used if the CRC bits of a DCI format are scrambled with a second C-RNTI value.
  • the UL MCS table can be implicitly determined by the aggregation level of a corresponding DCI format used for PUSCH scheduling.
  • the aggregation levels (ALs) in a US S may be divided into two sets, wherein the first set of ALs comprises of AL-1 and AL-2 and the second set of ALs comprise of AL-4 and AL-8.
  • the UE can use the UL 256QAM MCS table if the first set (i.e. AL-1 or AL-2) is used for DCI format transmission.
  • the legacy UL MCS table can be selected if the second set is used for DCI format transmission.
  • the UL MCS table may be implicitly indicated based on which DCI format is used for the corresponding PUSCH scheduling. For example, a UE can assume the legacy UL MCS table is selected for PUSCH transmission if it is scheduled by DCI format 0 regardless of the configured MCS table. The UE can assume the UL 256QAM MCS table is used for PUSCH transmission if UL 256QAM MCS table is configured for this UE and the PUSCH is scheduled by DCI format 4. In another instance, when more than one UL subframe set is configured for a given UE, the UL MCS table can be indicated by which UL subframe set is scheduled for PUSCH transmission.

  • the association between UCI offset parameter and the corresponding UL subframe set can be implicitly determined.
  • a first set of UCI offset parameters associated with the legacy UL MCS table can be used for determining the number of UCI REs on the first UL subframe set due to typically stronger cross-link interference than the second subframe set.
