7.1.5.1.2 Conformance requirements

References: The conformance requirements covered in the present TC are specified in: 3GPP TS 36.212 clause 5.3.3.1.1 and 36.213 clauses 8.4, 8.4.1 & 8.4,2.

[TS 36.212, clause 5.3.3.1.1]

DCI format 0 is used for the scheduling of PUSCH.

The following information is transmitted by means of the DCI format 0:

– Flag for format0/format1A differentiation – 1 bit, where value 0 indicates format 0 and value 1 indicates format 1A

– Hopping flag – 1 bit as defined in section 8.4 of [3]

– Resource block assignment and hopping resource allocation – bits

– For PUSCH hopping:

NUL_hop MSB bits are used to obtain the value of as indicated in subclause [8.4] of [3]

– bits provide the resource allocation of the first slot in the UL subframe

– For non-hopping PUSCH:

– bits provide the resource allocation in the UL subframe as defined in section 8.1 of [3]

[TS 36.213, clause 8.4]

The UE shall perform PUSCH frequency hopping if the single bit frequency hopping (FH) field in a corresponding PDCCH with DCI format 0 is set to 1 otherwise no PUSCH frequency hopping is performed.  

A UE performing PUSCH frequency hopping shall determine its PUSCH resource allocation (RA) for the first slot of a subframe (S1) including the lowest index PRB () in subframe n from the resource allocation field in the latest PDCCH with DCI format 0 for the same transport block. If there is no PDCCH for the same transport block, the UE shall determine its hopping type based on

– the hopping information in the most recent semi-persistent scheduling assignment PDCCH, when the initial PUSCH for the same transport block is semi-persistently scheduled or

– the random access response grant for the same transport block, when the PUSCH is initiated by the random access response grant.

The resource allocation field in DCI format 0 excludes either 1 or 2 bits used for hopping information as indicated by Table 8.4-1 below where the number of PUSCH resource blocks is defined as

For type 1 and type 2 PUSCH hopping, if is an odd number where defined in [3]. in other cases. The size of the resource allocation field in DCI format 0 after excluding either 1 or 2 bits shall be , where NUL_hop = 1 or 2 bits. The number of contiguous RBs that can be assigned to a type-1 hopping user is limited to . The number of contiguous RBs that can be assigned to a type-2 hopping user is limited to min(,),where the number of sub-bands is given by higher layers.

A UE performing PUSCH frequency hopping shall use one of two possible PUSCH frequency hopping types based on the hopping information. PUSCH hopping type 1 is described in section 8.4.1 and type 2 is described in section 8.4.2.

The parameter Hopping-mode provided by higher layers determines if PUSCH frequency hopping is “inter-subframe” or “intra and inter-subframe”.

[TS 36.213, clause 8.4.1]

For PUSCH hopping type 1 the hopping bit or bits indicated in Table 8.4-1 determine as defined in Table 8.4-2. The lowest index PRB () of the 1st slot RA in subframe i is defined as , where , and is obtained from the uplink scheduling grant as in Section 8.4 and Section 8.1.

The lowest index PRB () of the 2nd slot RA in subframe i is defined as .

The set of physical resource blocks to be used for PUSCH transmission are contiguously allocated resource blocks from PRB index for the 1st slot, and from PRB index for the 2nd slot, respectively, where is obtained from the uplink scheduling grant as in Section 8.4 and Section 8.1.

If the Hopping-mode is "inter-subframe", the 1st slot RA is applied to even CURRENT_TX_NB, and the 2nd slot RA is applied to odd CURRENT_TX_NB, where CURRENT_TX_NB is defined in [8].

– UEs that are configured with two CSI measurement sets by higher layers with the parameter csi-MeasSubframeSet, and when the corresponding DCI format is mapped onto the UE specific search space given by the C-RNTI as defined in [3];

the 3-bit field applies to UEs that are configured with more than five DL cells and when the corresponding DCI format is mapped onto the UE specific search space given by the C-RNTI as defined in [3];

otherwise the 1-bit field applies

– SRS request –1 bit. The interpretation of this field is provided in section 8.2 of [3]

– Modulation order override – 1 bit as defined in section 8.6.1 of [3]

– Precoding information: number of bits as specified in Table 5.3.3.1.8-1. This field is present only if the higher layer parameter transmissionModeUL is configured to be transmission mode 2. Bit field as shown in Table 5.3.3.1.8-2 and Table 5.3.3.1.8-3, where only codeword 0 is enabled and the indexes corresponding to 1 layer are used. Note that TPMI for 2 antenna ports indicates which codebook index is to be used in Table 5.3.3A.2-1 of [2], and TPMI for 4 antenna ports indicates which codebook index is to be used in Table 5.3.3A.2-2, Table 5.3.3A.2-3, Table 5.3.3A.2-4 and Table 5.3.3A.2-5 of [2]. The transport block is mapped to codeword 0.

If the number of information bits in format 0C mapped onto a given search space is less than the payload size of format 1A for scheduling the same serving cell and mapped onto the same search space (including any padding bits appended to format 1A), zeros shall be appended to format 0C until the payload size equals that of format 1A.

[TS 36.211, clause 5.3.4]

For UEs configured with PUSCHEnh-Configuration, the number of PUSCH subframe repetitions and the PRB resources for PUSCH transmission in the first subframe are obtained from the DCI as described in clause 5.3.3.1.1C in [3]. PUSCH frequency hopping is enabled when the higher-layer parameters pusch-HoppingOffsetPUSCHEnh and interval-ULHoppingPUSCHEnh are set and the frequency hopping flag in DCI format 0C indicates frequency hopping, otherwise frequency hopping is disabled. If frequency hopping is not enabled for PUSCH, the PUSCH repetitions are located at the same PRB resources as in the first subframe. If frequency hopping is enabled for PUSCH, PUSCH is transmitted in subframe within the consecutive uplink subframes using the PRB resources starting at PRB index

where is the absolute subframe number of the first UL subframe carrying the PUSCH and is given by the higher-layer parameter pusch-HoppingOffsetPUSCHEnh and is given by the higher-layer parameter interval-ULHoppingPUSCHEnh.

Message

1

The SS ignores scheduling requests and does not allocate any uplink grant.

2

SS transmits a MAC PDU including 8 (FDD)/4(TDD) RLC SDU’s

<–

MAC PDU

3

The UE transmits a Scheduling Request

–>

Scheduling Request

Exception: Steps 4 to 5 are repeated 8 ([FDD)/4(TDD) times

4

The SS allocates an UL Grant DCI format 0C. allowing the UE to return 1 RLC SDU as received in step 2. ‘Frequency hopping flag’ set as 1, ‘Repetition number’ set as 011

<–

(UL Grant (C-RNTI))

Exception: Steps 5 are repeated such that UE sends data in 8 consecutive UL subframes.
