DETAILED DESCRIPTION
[0018] Various wireless cellular communication systems have been implemented or are being proposed, including a 3rd Generation Partnership Project (3GPP) Universal Mobile Telecommunications System (UMTS), a 3GPP Long-Term Evolution (LTE) system, a 3GPP LTE-Advanced system, and a 5th Generation wireless system / 5th Generation mobile networks (5G) system / New Radio (NR) system. Next-generation wireless cellular communication systems may provide support for massive numbers of user devices like Narrowband Internet-of-Things (NB-IoT) devices, Cellular Internet-of-Things (CIoT) devices, or Machine-Type Communication (MTC) devices. Such devices may have very low device complexity, may be latency -tolerant, and may be designed for low throughput and very low power consumption.
[0019] One objective pertaining to Further Enhanced MTC (FeMTC) may be higher data rates. This may relate to, among other things: implementing Hybrid Automatic Repeat Request (HARQ) Acknowledgement (ACK) bundling in Coverage Enhancement (CE) mode A in Half Duplex Frequency Division Duplex (HD-FDD); implementing larger maximum Transport Block Sizes (TBSes); implementing larger maximum Physical Downlink Shared Channel (PDSCH) / Physical Uplink Shared Channel (PUSCH) channel bandwidth in connected mode (at least in CE mode A), in order to enhance support for various applications and scenarios (such as voice and audio streaming); and implementing up to 10 Downlink (DL) HARQ processes in CE mode A in Full-Duplex FDD (FD-FDD). Accordingly, for example, in order to support higher data-rate operations for FeMTC, Bandwidth Reduced (BR) Low Complexity (BL) / CE UEs with a maximum bandwidth (BW) of 5 megahertz (MHz) (e.g., 3GPP Release-14 compliant BL UEs) may implement a maximum TBS of 4008 bits for PDSCH, 4008 bits for PUSCH, or both.
[0020] Meanwhile, a maximum TBS for enhanced MTC (eMTC) UEs may be 1000 bits (e.g., for 3GPP Release-13 compliant eMTC UEs). In supporting larger TBSes for some UEs (e.g., for 5 MHz 3GPP Release-14 BL UEs), soft buffer size may increase. With Full Buffer Rate Matching (FBRM) for channel encoding and decoding, the equation
N*96* [(X+28)/32] may be used for calculating the soft buffer size, where N may be a maximum number of DL HARQ processes, and X may be a maximum DL TBS.
[0021] So, as a first example, with a maximum TBS of 1000 bits and a maximum of 8
DL HARQ processes, an eMTC UE (e.g., a Release 13 eMTC UE) may have a total number of soft channel bits of 25344. As a second example, with a maximum TBS of 4008 bits and maximum of 8 DL HARQ processes, a BL UE (e.g., a MHz 3 GPP Release-14 BL UE) may have a total number of soft channel bits of 97536.
[0022] As the soft buffer size may be a factor that impacts the cost of a device, reducing a soft buffer size may be advantageous (e.g., for 5 MHz 3GPP Release-14 BL UEs). A first option may be to establish a soft buffer size of N*96*([(X+28)/32], where N may be a maximum number of DL HARQ processes, and X may be a maximum DL TBS. A second option may be to establish a soft buffer size smaller than the soft buffer size of the first option.
[0023] A reduction in soft buffer size may be facilitated by using a Limited Buffer
Rate matching (LBRM) technique, where the rate matching procedure may be such that a storage requirement is reduced by enforcing an earlier wrap-around of a virtual circular buffer, and accordingly, a Redundancy Version (RV) location may be compressed to fit all 4 RVs within a wrap-around period. With LBRM (for, e.g., Category 3, Category 4, and Category 5 UEs, which may correspond with a maximum effective mother code rate of 2/3), then a total number of soft channel bits may be reduced to 50% of the above values. For the second example above, a BL UE (e.g., a MHz 3 GPP Release-14 BL UE) with 8 DL HARQ processes may have a total number of soft channel bits of 48768.
[0024] Figs. 1A and IB illustrate scenarios of link-level performance for Physical
Downlink Shared Channel (PDSCH), in accordance with some embodiments of the disclosure. A first scenario 110 and a second scenario 120 may compare the performance for a PDSCH TBS of 4008 with Full Buffer Rate Matching (FBRM) to the performance for a PDSCH TBS of 4008 with LBRM for a soft buffer size reduction of 50%. First scenario 110 may correspond with a modulation order of 2 (e.g., QPSK), while second scenario 120 may correspond with a modulation order of 4 (e.g., 16QAM). (First scenario 110 and second scenario 120 may correspond with cross-SF CE over up to 2 SFs, and various Repetition Levels (RLs), and the channel simulated may be EPA-1 Hz.)
[0025] So, with an RL of 1 (e.g., only initial transmission), for the case of TBS of
4008 bits over 24 Physical Resource Blocks (PRBs), a reduction of soft buffer size may correspond with a performance degradation between FBRM and LBRM a modulation order of 4 (e.g., 16QAM); while a reduction of soft buffer size may correspond with almost the same performance between FBRM and LBRM for a modulation order of 2 (e.g., QPSK). To clarify possible reasons for such observations, the following may be calculated:
[0026] 1. With LBRM of 50% soft buffer size reduction, the soft buffer size may be
Nsoft = 48768 bits.
[0027] 2. A number of rows in a coded bit matrix may be:
Figure imgf000006_0001
Figure imgf000006_0002
[0028] 3. A number of coded bits may be:
= Nrow * Ncolumn * 3 = 127 * 32 * 3 = 12192. [0029] 4. A soft buffer size for a code block may be:
son ) (48768 )
Ncb = min sof t , /ew [ = min j— 5— , 12192 J = 6096
M D, L-HARQ I 8
where Nsoft may be a size of the soft buffer, and MDL-HARQ may be a number of DL HARQ processes.
[0030] 5. An RV starting location may be:
Net
= Nrow * I 2 * * rvidx + 2 where rvidx may be an index of RV.
[0031] 6. In the considered setup, ko may have the following values, where every 12 columns may have a new RV. For RV0:
Ncb
— Nrow * * rvir]Y + 2 = 127 * 2 = 254
8 * Nr
For RVl :
Ncb 6096
ko = Nrow * 2 * rvidx
8*Nr + 2) = 127 * * 1 + 2 = 127 * 14 =
8*127
1778
For RV2:
6096
I row * 2 * 2
8*Nr * rvldx + 2) = 127 * (
8*127 * 2 + 2 = 127 * 26
3302
For RV3:
N, cb 6096
^0 = Nrow * rvidx + 2 ) = 127 * I 2 * * 3 + 2 = 127 * 38
8 * Nr 8 * 127
= 4826
[0032] 7. With 24 PRBs, 16QAM, a Control Format Indicator (CFI) of 3, and 2 Cell-
Specific Reference Signal (CRS) ports, a number of rate matched bits may be E = 24*(12*11- 12)*4 = 11520, while with 24 PRBs and QPSK, a number of rate matched bits may be E = 5760.
[0033] 8. Perform a rate matching procedure. Fig. 2 illustrates a rate matching procedure, in accordance with some embodiments of the disclosure. A rate matching procedure 200, which may be similar to a rate matching procedure form 3GPP Technical Specification (TS) 36.212, may be performed. [0034] Based on these calculations, various things may help explain the performance degradation of LBRM in certain cases (e.g., for cases with 4008 bits transmitted over 24 PRBs with 16QAM).
[0035] In the example considered above in which the number of rate matched bits may be E = 11520, if LBRM is used with NCb = 6096, columns from 1 to 48 may all be included in an initial transmission. Compared to an FBRM case with NCb = 12192, a significant amount of parity bits might not be included in the transmission with LBRM even though a number of rate-matched bits for the transmission may be large, and thus the performance may degrade with LBRM (as discussed further herein).
[0036] Alternatively, in an example considered in which the number of rate matched bits may be E = 5760, the bits that can be carried within one transmission may be the same for LBRM and FBRM, and thus the performance may be expected to be the same.
[0037] Therefore, when LBRM is adopted for the above example, the performance with E = 5760 (e.g., with QPSK) may be better than the performance with E = 1 1520 (e.g., with 16QAM). This may be because a coding gain from 16QAM with LBRM may be limited due to a reduced soft buffer size, while QPSK may have better detection performance.
[0038] Accordingly, discussed herein are proposed new Modulation and Coding
Scheme (MCS) tables (e.g., for 5 MHz 3 GPP Release-14 BL UEs), which may
advantageously improve performance with adoption of LBRM. Performance may advantageously improve based upon a change in a modulation order relative to that defined in legacy LTE (e.g., from higher values to 2 for certain cases of TBS and RB allocation), depending on the reduced soft buffer size.

[0052] Figs. 3A and 3B illustrate a table of TBSes for Bandwidth Reduced BL / CE
UEs, in accordance with some embodiments of the disclosure. Table 1 (which may have a first part 310, a second part 320, and a third part 330) may be substantially similar to a TBS table in 3GPP Release-13 LTE (e.g., for 3 GPP Release-13 BL/CE UEs).
[0053] A minimum soft buffer size considered for LBRM may be 50% of a soft buffer size for FBRM, where FBRM may have NCb < 12192 and LBMR may have NCb≤ 6096. The following conditions may accordingly be considered to determine cases for performance improvement with LBRM.
[0054] 1. Any TBS smaller than or equal to 50% of a maximum TBS may not be impacted by the LBRM. In other words, TBS < 2004 bits may not be impacted.
[0055] 2. Note that some modulation schemes (e.g., modulation schemes supported for 3GPP Release-14 BL/CE UEs) may be merely QPSK and 16QAM. The QPSK cases do not need to be considered, as it is already the smallest modulation order. [0056] 3. The cases with a number of output bits E < 6096 may not be important to consider, since the number of bits that can be read out for rate matching may be limited by E, and therefore the bits that are rate matched from a coded matrix may be the same regardless of the soft buffer size.
[0057] 4. A TBS may be disposed to not being larger than E with QPSK, otherwise the performance may be significantly diminished.
[0058] With the above conditions, cases with RB allocations < 12 (which have
E < 5760) and with 16QAM may be excluded from consideration, and cases with a number of RBs between 13 and 25, and a TBS index (ITBS) greater than 8.
[0059] Figs. 4A and 4B illustrate a table of TBSes and Resource Block (RB) allocations, in accordance with some embodiments of the disclosure. Table 2 summarizes cases of numbers of allocated PRBs (N PRB) and I TBS that may be considered for performance improvement with LBRM. Table 2 has a first TBS table 410 and a second TBS table 420. First TBS table 410 may be obtained by truncating a 3GPP Release-13 LTE TBS table to be up to 4008 bits, while second TBS table 420 may be obtained by truncating the 3GPP Release-13 LTE TBS table and additionally replacing some or all of the maximum TBS values greater than 4008 by 4008 bits. Either version of the TBS table may be suitable for adoption for UEs with maximum of 5 MHz channel BW.
[0060] First TBS table 410 may have a set of first cases 41 1 and a set of second cases
412. QPSK may be used in first cases 411 , and 16QAM may still be used in second cases 412. Second TBS table 420 may have a set of first cases 421 and a set of second cases 422. QPSK may be used in first cases 421 , and 16QAM may still be used in second cases 422. Second TBS table 420 may also have a set of third cases 423 (emphasized in bold and italics), in which second TBS table 420 differs from first TBS table 410.
[0061] Fig. 5 illustrates a table of numbers of rate-matched bits with Quadrature
Phase-Shift Keying (QPSK) and 16 Quadrature Amplitude Modulation (16QAM), in accordance with some embodiments of the disclosure. Table 3 may provide E values (e.g., numbers of rate matched bits) with QPSK and with 16QAM, for cases summarized in Table 2 of Figs. 4A and 4B
[0062] As described herein, for some of the cases of TBS and RB allocation that are closer to a maximum TBS of 4008 bits, it may be beneficial to use QPSK modulation rather than 16QAM, to advantageously limit a performance degradation from LBRM compared to FBRM. [0063] A maximum effective mother code rate may be denoted as Rm,max, and a maximum TBS may be denoted as TBSmax. A process soft buffer size may then be:
B = TBSmax / Rm,max.
The maximum TBS may be calculated by:
TBSmax = NRB,max*NRE*MCRo ,max,
Where NRE may be a number of REs per PRB, NRB.max may denote a maximum number of PRBs, and MCRo ,max Jmax *Ro,max may denote a maximum initial modulation and coding rate. Thus, the process soft buffer size may be:
B = TBSmax / Rm,max = NRB,max*NRE* Umax ,max / Rm,max.
[0064] For a given TBS transmitted over NRB RBS and MCRo = qo*Ro in an initial transmission, a mother code rate may be:
Rm=NRB*NRE*MCRo / B = NRB / NRB.max * Rm,max / (qmax*Ro,max) * (qo * Ro)
Given NRB / NRB.max≤ 1 and qo / qmax≤l, it may be that Rm / Ro≤ Rm,max / Ro.max, where the ratio Rm / Ro may indicate a utilization of the soft buffer. When Rm / Ro≤ 1, an implication may be that an initial transmission does not exhaust the soft buffer, and performance may not be expected to be different between LBRM and FBRM. On the other hand, when
Rm / Ro > 1, an initial transmission may exhaust the soft buffer, and performance with LBRM may degrade compared to FBRM.
[0065] For example, consider a soft buffer size reduction of 50% with LBRM. For
4008 bits transmitted over 24 PRBs with 16QAM, it may be that NRB / NRB.max = 24 / 24 = 1, qo / qmax = 4 / 4 = 1, Rm,max = 2/3, and Ro,max = 1/3, and thus Rm / Ro=2. On the other hand, for 4008 bits transmitted over 24 PRBs with QPSK, it may be that NRB / NRB.max = 24 / 24 = 1, qo / qmax = 2 / 4 = 1 / 2, Rm,max = 2/3, and Ro,max = 1/3, and thus Rm / Ro=l.
[0066] Therefore, in the given example, an initial transmission with 16QAM may exhaust the soft buffer size, and LBRM may result in performance degradation, while QPSK may not exhaust the soft buffer size, and thus no performance difference between LBRM and FBRM may be expected. This is aligned with the observations depicted in Fig. 1.
[0067] Accordingly, in some embodiments, QPSK may be used instead of 16QAM for some cases of TBS and RB allocation (e.g., for first cases 411 and/or first cases 421 of Table 2). Meanwhile, in some embodiments, 16QAM (e.g., similar to 3GPP Release-13 LTE) may be used for some cases of TBS and RB allocation (e.g., for second cases 412 and/or second cases 422 of Table 2).
[0068] In some embodiments, the following cases of TBS and RB allocation may use
QPSK: (1) TBS index ITBS from 9 to 12 for resource allocation of 13-17 PRBs; (2) TBS index ITBS from 9 to 1 1 for resource allocation of 18-20 PRBs; (3) TBS index ITBS from 9 to 10 for resource allocation of 21-23 PRBs use QPSK; and/or (4) TBS index ITBS=9 for resource allocation of 24-25 PRBs.
[0069] For some embodiments, the following cases of TBS and RB allocation may use QPSK: (1) TBS index ITBS from 9 to 12 for resource allocation of 13-19 PRBs; (2) TBS index ITBS from 9 to 1 1 for resource allocation of 20-22 PRBs; (3) TBS index ITBS from 9 to 10 for resource allocation of 23-24 PRBs; and/or (4) TBS index ITBS=9 for resource allocation of 25 PRBs.
[0070] In some embodiments, TBS may be updated to 4008 for ITBS = 14 with
15-PRB allocation, ITBS = 13 with 16-PRB allocation and/or 17-PRB allocation, ITBS = 12 with 18-PRB allocation and/or 19-PRB allocation, ITBS = 1 1 with 21-PRB allocation and/or 22-PRB allocation, and/or ITBS = 10 with 24-PRB allocation.
[0071] For some embodiments, other cases of TBS and RB allocation may follow, for example, 3GPP Release-13 LTE TBS and MCS tables. Note that ITBS = 9 may support both QPSK and 16QAM, and following the above reasoning, merely QPSK may be used for RBs > 12.
[0072] In some embodiments, an additional constraint on the maximum coding rate,
(e.g., ¾) may be applied. However, this may reduce the number of cases where QPSK may advantageously be used.
[0073] Figs. 6A and 6B illustrate a table of coding rates for corresponding TBS and
RB allocations, in accordance with some embodiments of the disclosure. Table 4
summarizes cases of coding rates for and that may be considered for performance improvement with LBRM. Table 4 may show a modulation scheme to be used when a maximum coding rate of 3/4 is added as an additional constraint. Table 4 has a first TBS table 610 and a second TBS table 620. First TBS table 610 may be based upon TBS values shown in first TBS table 410 of Fig. 4A, while second TBS table 620 may be based upon TBS values shown in second TBS table 420 of Fig. 4B.
[0074] First TBS table 610 may have a set of first cases 611 and a set of second cases
612. QPSK may be used in first cases 611 , and 16QAM may still be used in second cases 612. Second TBS table 620 may have a set of first cases 621 and a set of second cases 622. QPSK may be used in first cases 621 , and 16QAM may still be used in second cases 622. Second TBS table 620 may also have a set of third cases 623 (emphasized in bold and italics), in which second TBS table 620 differs from first TBS table 610. For of 11 or 12, Table 2 indicates that QPSK may be used for various cases of NPRB, while Table 4 indicates that 16QAM may be used for similar cases of NPRB.
[0075] In some embodiments, the following cases of TBS and RB allocation may use
QPSK: (1) TBS index ITBS from 9 to 10 for resource allocation of 13-23 PRBs; and/or (2) TBS index ITBS=9 for resource allocation of 24-25 PRBs.
[0076] For some embodiments, the following cases of TBS and RB allocation may use QPSK: (1) TBS index ITBS from 9 to 10 for resource allocation of 13-24 PRBs; and/or (2) TBS index ITBS=9 for resource allocation of 25 PRBs.
[0077] In some embodiments, other cases (e.g., cases not using QPSK) may follow
3GPP Release-13 LTE TBS and MCS. Note that a coding rate constraint 3/4 is considered as an illustrative example, and other coding rate constraint values are not precluded.
[0078] For some embodiments, both QPSK and 16QAM may be supported for cases of TBS and RB allocation discussed herein, instead of moving from 16QAM to QPSK. The replacement of QPSK by 16QAM for the same supported TBS and resource allocation cases may merely be beneficial as long as the resulting effective code rate is not too high, or if the performance may rely on use of Incremental Redundancy (IR) based gains from cycling of Redundancy Versions (RVs).
[0079] Thus, in some embodiments, for certain cases of TBS (e.g., ITBS) and resource allocation (e.g., NPRB), both QPSK and 16QAM may be supported. In various embodiments, the network may have the ability to indicate which modulation (e.g., QPSK or 16QAM) will be used, depending on other characteristics of the concerned PDSCH transmission. For example, without repetition, 16QAM may have better performance than QPSK, due to additional coding gain, while with repetitions, QPSK may have better performance than 16QAM, due to achieving additional coding gain from RV cycling and better detection performance.
[0080] In some embodiments, the following cases of TBS and RB allocation may support both QPSK and 16QAM: (1) TBS index ITBS from 9 to 12 for resource allocation of 13-17 PRBs; (2) TBS index ITBS from 9 to 11 for resource allocation of 18-20 PRBs; (3) TBS index ITBS from 9 to 10 for resource allocation of 21-23 PRBs; and/or (4) TBS index ITBS=9 for resource allocation of 24-25 PRBs.
[0081] For some embodiments, the following cases of TBS and RB allocation may support both QPSK and 16QAM: (1) TBS index ITBS from 9 to 12 for resource allocation of 13-19 PRBs; (2) TBS index ITBS from 9 to 11 for resource allocation of 20-22 PRBs; (3) TBS index ITBS from 9 to 10 for resource allocation of 23-24 PRBs; and/or (4) TBS index ITBS=9 for resource allocation of 25 PRBs.
[0082] Since performance degradation with QPSK may occur merely when the code rate is very high, QPSK may be used merely when the resulting code rate with QPSK is not very high. For example, for cases of TBS and RB allocation satisfying ITBS > 8 and
NPRB > 12, and a code rate with QPSK no larger than a number X (e.g., X=3/4), merely QPSK may be supported. For cases of TBS and RB allocation with ITBS > 8, NPRB > 12, and a code rate with QPSK greater than X but smaller than a number Y (e.g., Y=l), both QPSK and 16QAM may be supported. For cases of TBS and RB allocation with ITBS > 8,
NPRB > 12, and a code rate with QPSK equal to or greater than Y, merely 16QAM may be supported.
[0083] Fig. 7 illustrates a table of TBSes and RB allocations, in accordance with some embodiments of the disclosure. Table 5 illustrates an example of embodiments in which cases of TBS and RB allocation may support both QPSK and 16QAM based on numbers X and Y, with X=3/4 and Y=l.
[0084] A TBS table 710 may have a set of first cases 711, a set of second cases 712, and a set of third cases 713. QPSK may be used in first cases 711, 16QAM may still be used in second cases 712, and both QPSK and 16QAM may be supported in third cases 713. In some embodiments,
[0085] In some embodiments, for cases of TBS with ITBS between 9 and 10 and an RB allocation of 13-25 PRBs, merely QPSK may be used. For cases of TBS with ITBS = 11 and an RB allocation of 13-22 PRBs, with ITBS = 12 and an RB allocation of 13-19 PRBs, and/or with ITBS = 13 and an RB allocation of 17 PRBs, both QPSK and 16QAM may be supported.
[0086] For the TBS and RB allocations which support both QPSK and 16QAM, the modulation to be used may be indicated in various ways. In some embodiments, the modulation may be dynamically indicated (e.g., via Downlink Control Information (DCI)). In 3 GPP Release-13 LTE, a TBS with ITBS = 9 may support both QPSK and 16QAM, and these two cases may correspond to two rows in the modulation and TBS index table.
Similarly, additional rows may be added to the modulation and TBS index table to characterize selection of TBS with QPSK and selection of TBS with 16QAM, for TBSs supporting both.
[0087] In some embodiments, additional MCS indices may be advantageous, and thus additional bits may be added in the DCI. For some DCI-based embodiments, additional bits may be added, such as in a "modulation and coding scheme" field in the DCI. One example of the modulation and TBS index table may be given by Table 6 below (for embodiments which may have TBSes and corresponding supported modulations in accordance with Table 5).
Table 6. PDSCH
Figure imgf000017_0001
[0088] For some DCI-based embodiments, one extra bit may be added to indicate or select the modulation. This bit may be interpreted by a UE merely for cases of TBS and RB allocation which are specified to support both QPSK and 16QAM. For other cases, the UE may still follow the modulation indicated by the "modulation and coding scheme" field, and may ignore this indication.
[0089] In some embodiments, a selection between QPSK modulation and 16QAM modulation may be indicated semi-statically via higher layer signaling (e.g., via UE-specific Radio Resource Control (RRC) signaling). For some embodiments, for TBSs supporting both QPSK and 16QAM, UEs experiencing good coverage may be signaled to use 16QAM, while UEs experiencing poor coverage may be signaled to use QPSK.
[0090] For some embodiments, an implicit indication may be used. The modulation selection for TBSs supporting both QPSK and 16QAM may be related to various factors, such as TBS, RB allocation, number of repetitions, and so on. Thus, an implicit indication rule may be predefined or otherwise predetermined. For example, for cases of TBS and RB allocation supporting both QPSK and 16QAM, QPSK may be used when the RL is greater than a number Z (e.g., Z = 1 or Z = 2) assuming use of RV cycling for Incremental
Redundancy (IR) coding gains, or when a code rate when assuming QPSK is not above a specified value (e.g., 3/4), otherwise 16QAM may be used. The value of Z may be predefined or otherwise predetermined, or may be semi-statically indicated via higher-layer signaling.

Fig. 8 includes block diagrams of an eNB 810 and a UE 830 which are operable to co-exist with each other and other elements of an LTE network. High-level, simplified architectures of eNB 810 and UE 830 are described so as not to obscure the embodiments. It should be noted that in some embodiments, eNB 810 may be a stationary non-mobile device.
[0092] eNB 810 is coupled to one or more antennas 805, and UE 830 is similarly coupled to one or more antennas 825. However, in some embodiments, eNB 810 may incorporate or comprise antennas 805, and UE 830 in various embodiments may incorporate or comprise antennas 825.

[0097] Accordingly, in some embodiments, eNB 810 may be a device comprising an application processor, a memory, one or more antenna ports, and an interface for allowing the application processor to communicate with another device.
[0098] As is also illustrated in Fig. 8, in some embodiments, UE 830 may include a physical layer circuitry 832, a MAC circuitry 834, a processor 836, a memory 838, a hardware processing circuitry 840, a wireless interface 842, and a display 844. A person skilled in the art would appreciate that other components not shown may be used in addition to the components shown to form a complete UE.
[0099] In some embodiments, physical layer circuitry 832 includes a transceiver 833 for providing signals to and from eNB 810 (as well as other eNBs). Transceiver 833 provides signals to and from eNBs or other devices using one or more antennas 825. In some embodiments, MAC circuitry 834 controls access to the wireless medium. Memory 838 may be, or may include, a storage media/medium such as a magnetic storage media (e.g., magnetic tapes or magnetic disks), an optical storage media (e.g., optical discs), an electronic storage media (e.g., conventional hard disk drives, solid-state disk drives, or flash-memory -based storage media), or any tangible storage media or non-transitory storage media. Wireless interface 842 may be arranged to allow the processor to communicate with another device. Display 844 may provide a visual and/or tactile display for a user to interact with UE 830, such as a touch-screen display. Hardware processing circuitry 840 may comprise logic devices or circuitry to perform various operations. In some embodiments, processor 836 and memory 838 may be arranged to perform the operations of hardware processing circuitry 840, such as operations described herein with reference to logic devices and circuitry within UE 830 and/or hardware processing circuitry 840.
[00100] Accordingly, in some embodiments, UE 830 may be a device comprising an application processor, a memory, one or more antennas, a wireless interface for allowing the application processor to communicate with another device, and a touch-screen display.
[00101] Elements of Fig. 8, and elements of other figures having the same names or reference numbers, can operate or function in the manner described herein with respect to any such figures (although the operation and function of such elements is not limited to such descriptions). For example, Figs. 9-10 and 13-14 also depict embodiments of eNBs, hardware processing circuitry of eNBs, UEs, and/or hardware processing circuitry of UEs, and the embodiments described with respect to Fig. 8 and Figs. 9-10 and 13-14 can operate or function in the manner described herein with respect to any of the figures.
[00102] In addition, although eNB 810 and UE 830 are each described as having several separate functional elements, one or more of the functional elements may be combined and may be implemented by combinations of software-configured elements and/or other hardware elements. In some embodiments of this disclosure, the functional elements can refer to one or more processes operating on one or more processing elements. Examples of software and/or hardware configured elements include Digital Signal Processors (DSPs), one or more microprocessors, DSPs, Field-Programmable Gate Arrays (FPGAs), Application Specific Integrated Circuits (ASICs), Radio-Frequency Integrated Circuits (RFICs), and so on.

With reference to Fig. 8, a UE may include various hardware processing circuitries discussed herein (such as hardware processing circuitry 900 of Fig. 9), which may in turn comprise logic devices and/or circuitry operable to perform various operations. For example, in Fig. 8, UE 830 (or various elements or components therein, such as hardware processing circuitry 840, or combinations of elements or components therein) may include part of, or all of, these hardware processing circuitries.

[00106] Antenna ports 905 and antennas 907 may be operable to provide signals from a UE to a wireless communications channel and/or an eNB, and may be operable to provide signals from an eNB and/or a wireless communications channel to a UE. For example, antenna ports 905 and antennas 907 may be operable to provide transmissions from UE 830 to wireless communication channel 850 (and from there to eNB 810, or to another eNB). Similarly, antennas 907 and antenna ports 905 may be operable to provide transmissions from a wireless communication channel 850 (and beyond that, from eNB 810, or another eNB) to UE 830.
[00107] Hardware processing circuitry 900 may comprise various circuitries operable in accordance with the various embodiments discussed herein. With reference to Fig. 9, hardware processing circuitry 900 may comprise a first circuitry 910, a second circuitry 920, and/or a third circuitry 930.

Output baseband signals may be provided to the baseband circuitry 1304 for further processing. In some embodiments, the output baseband signals may be zero-frequency baseband signals, although this is not a requirement. In some embodiments, mixer circuitry 1306A of the receive signal path may comprise passive mixers, although the scope of the embodiments is not limited in this respect.

[00194] In some embodiments, the output baseband signals and the input baseband signals may be analog baseband signals, although the scope of the embodiments is not limited in this respect. In some alternate embodiments, the output baseband signals and the input baseband signals may be digital baseband signals. In these alternate embodiments, the RF circuitry 1306 may include analog-to-digital converter (ADC) and digital-to-analog converter (DAC) circuitry and the baseband circuitry 1304 may include a digital baseband interface to communicate with the RF circuitry 1306.

For example, synthesizer circuitry 1306D may be a delta-sigma synthesizer, a frequency multiplier, or a synthesizer comprising a phase-locked loop with a frequency divider.
[00197] The synthesizer circuitry 1306D may be configured to synthesize an output frequency for use by the mixer circuitry 1306A of the RF circuitry 1306 based on a frequency input and a divider control input. In some embodiments, the synthesizer circuitry 1306D may be a fractional N/N+l synthesizer.
[00198] In some embodiments, frequency input may be provided by a voltage controlled oscillator (VCO), although that is not a requirement. Divider control input may be provided by either the baseband circuitry 1304 or the applications processor 1302 depending on the desired output frequency. In some embodiments, a divider control input (e.g., N) may be determined from a look-up table based on a channel indicated by the applications processor 1302.
[00199] Synthesizer circuitry 1306D of the RF circuitry 1306 may include a divider, a delay-locked loop (DLL), a multiplexer and a phase accumulator. In some embodiments, the divider may be a dual modulus divider (DMD) and the phase accumulator may be a digital phase accumulator (DP A). In some embodiments, the DMD may be configured to divide the input signal by either N or N+l (e.g., based on a carry out) to provide a fractional division ratio. In some example embodiments, the DLL may include a set of cascaded, tunable, delay elements, a phase detector, a charge pump and a D-type flip-flop. In these embodiments, the delay elements may be configured to break a VCO period up into Nd equal packets of phase, where Nd is the number of delay elements in the delay line. In this way, the DLL provides negative feedback to help ensure that the total delay through the delay line is one VCO cycle.
[00200] In some embodiments, synthesizer circuitry 1306D may be configured to generate a carrier frequency as the output frequency, while in other embodiments, the output frequency may be a multiple of the carrier frequency (e.g., twice the carrier frequency, four times the carrier frequency) and used in conjunction with quadrature generator and divider circuitry to generate multiple signals at the carrier frequency with multiple different phases with respect to each other. In some embodiments, the output frequency may be a LO frequency (fLO). In some embodiments, the RF circuitry 1306 may include an IQ/polar converter.

FEM circuitry 1308 may also include a transmit signal path which may include circuitry configured to amplify signals for transmission provided by the RF circuitry 1306 for transmission by one or more of the one or more antennas 1310. In various embodiments, the amplification through the transmit or receive signal paths may be done solely in the RF circuitry 1306, solely in the FEM 1308, or in both the RF circuitry 1306 and the FEM 1308.
[00202] In some embodiments, the FEM circuitry 1308 may include a TX/RX switch to switch between transmit mode and receive mode operation. The FEM circuitry may include a receive signal path and a transmit signal path. The receive signal path of the FEM circuitry may include an LNA to amplify received RF signals and provide the amplified received RF signals as an output (e.g., to the RF circuitry 1306). The transmit signal path of the FEM circuitry 1308 may include a power amplifier (PA) to amplify input RF signals (e.g., provided by RF circuitry 1306), and one or more filters to generate RF signals for subsequent transmission (e.g., by one or more of the one or more antennas 1310).
[00203] In some embodiments, the PMC 1312 may manage power provided to the baseband circuitry 1304. In particular, the PMC 1312 may control power-source selection, voltage scaling, battery charging, or DC-to-DC conversion. The PMC 1312 may often be included when the device 1300 is capable of being powered by a battery, for example, when the device is included in a UE. The PMC 1312 may increase the power conversion efficiency while providing desirable implementation size and heat dissipation characteristics.
[00204] While Fig. 13 shows the PMC 1312 coupled only with the baseband circuitry 1304. However, in other embodiments, the PMC 1312 may be additionally or alternatively coupled with, and perform similar power management operations for, other components such as, but not limited to, application circuitry 1302, RF circuitry 1306, or FEM 1308. [00205] In some embodiments, the PMC 1312 may control, or otherwise be part of, various power saving mechanisms of the device 1300. For example, if the device 1300 is in an RRC_Connected state, where it is still connected to the RAN node as it expects to receive traffic shortly, then it may enter a state known as Discontinuous Reception Mode (DRX) after a period of inactivity. During this state, the device 1300 may power down for brief intervals of time and thus save power.
[00206] If there is no data traffic activity for an extended period of time, then the device 1300 may transition off to an RRC Idle state, where it disconnects from the network and does not perform operations such as channel quality feedback, handover, and so on. The device 1300 goes into a very low power state and it performs paging where again it periodically wakes up to listen to the network and then powers down again. The device 1300 may not receive data in this state, in order to receive data, it must transition back to
RRC Connected state.
[00207] An additional power saving mode may allow a device to be unavailable to the network for periods longer than a paging interval (ranging from seconds to a few hours). During this time, the device is totally unreachable to the network and may power down completely. Any data sent during this time incurs a large delay and it is assumed the delay is acceptable.
[00208] Processors of the application circuitry 1302 and processors of the baseband circuitry 1304 may be used to execute elements of one or more instances of a protocol stack. For example, processors of the baseband circuitry 1304, alone or in combination, may be used execute Layer 3, Layer 2, or Layer 1 functionality, while processors of the application circuitry 1304 may utilize data (e.g., packet data) received from these layers and further execute Layer 4 functionality (e.g., transmission communication protocol (TCP) and user datagram protocol (UDP) layers). As referred to herein, Layer 3 may comprise a radio resource control (RRC) layer, described in further detail below. As referred to herein, Layer 2 may comprise a medium access control (MAC) layer, a radio link control (RLC) layer, and a packet data convergence protocol (PDCP) layer, described in further detail below. As referred to herein, Layer 1 may comprise a physical (PHY) layer of a UE/RAN node, described in further detail below.
[00209] Fig. 14 illustrates example interfaces of baseband circuitry, in accordance with some embodiments of the disclosure. As discussed above, the baseband circuitry 1304 of Fig. 13 may comprise processors 1304A-1304E and a memory 1304G utilized by said processors. Each of the processors 1304A-1304E may include a memory interface, 1404A- 1404E, respectively, to send/receive data to/from the memory 1304G.
[00210] The baseband circuitry 1304 may further include one or more interfaces to communicatively couple to other circuitries/devices, such as a memory interface 1412 (e.g., an interface to send/receive data to/from memory extemal to the baseband circuitry 1304), an application circuitry interface 1414 (e.g., an interface to send/receive data to/from the application circuitry 1302 of Fig. 13), an RF circuitry interface 1416 (e.g., an interface to send/receive data to/from RF circuitry 1306 of Fig. 13), a wireless hardware connectivity interface 1418 (e.g., an interface to send/receive data to/from Near Field Communication (NFC) components, Bluetooth® components (e.g., Bluetooth® Low Energy), Wi-Fi® components, and other communication components), and a power management interface 1420 (e.g., an interface to send/receive power or control signals to/from the PMC 1312.
[00211] It is pointed out that elements of any of the Figures herein having the same reference numbers and/or names as elements of any other Figure herein may, in various embodiments, operate or function in a manner similar those elements of the other Figure (without being limited to operating or functioning in such a manner).
[00212] Reference in the specification to "an embodiment," "one embodiment," "some embodiments," or "other embodiments" means that a particular feature, structure, or characteristic described in connection with the embodiments is included in at least some embodiments, but not necessarily all embodiments. The various appearances of "an embodiment," "one embodiment," or "some embodiments" are not necessarily all referring to the same embodiments. If the specification states a component, feature, structure, or characteristic "may," "might," or "could" be included, that particular component, feature, structure, or characteristic is not required to be included. If the specification or claim refers to "a" or "an" element, that does not mean there is only one of the elements. If the specification or claims refer to "an additional" element, that does not preclude there being more than one of the additional element.
