description

Field Embodiments of the present invention relate to the field of communications, and more particularly to downlink resource scheduling in wireless communication networks.

Background 3rd Generation Partnership Project (3 GPP) Long-term evolution (LTE) Release 10 (March 2011), which may also be referred to as LTE-Advanced (LTE-A), heterogeneous networks (HetNets) are relied upon to provide high-throughput communications. HetNets may include cells of different power classes, e.g., macro, pico, orphemto, and access class, e.g., open or closed-subscribergroup (CSG). Multicarrier operation with cross-carrier scheduling was provided to accommodate for intercell interference coordination (ICIC) in 3 GPP LTE Release 8 (September 2009). This is an alternative to the first component carrier that was considered to be more reliable. A single sub-frame cross-carrier scheduling operation is facilitated by a carrier identification field (CIF) of UE dedicated downlink control information (DO) to provide improved control and enable enhanced ICIC (elCIC) for HetNets.

In 3 GPP LTE Release 11, each component carrier may have its own time-division duplexing (TDD) uplink downlink (UL-DL) configuration. However, aggregation of carriers with different TDD UL-DL configurations may complicate cross-carrier scheduling.

[0010] Figure 1 schematically illustrating a wireless communication network 100 initing with various embodiments. Wireless communication network 100 (LTE-A) network such as evolved universal mobile telecommunication system (UMTS) terrestrial radio access network (E-UTRAN). The network 100 may include: a node base station (eNB) 104, configured to wirelessly communicate with a terminal, eg, user equipment (UE). LTE-A network, some implementations of wireless access networks.

A number of component carriers (CCs) may be aggregated for communication between the eNB 104 and the UE 108. In an initial connection establishment, the UE 108 is a capable of utilizing carrier aggregation (CA). 108 may use a primary CC, which may also be used as CC 0. Subsequently, the UE 108 may connect with one or more secondary cells (Scells) of the eNB 104 utilizing one or more secondary CCs. These connections may also be used to provide additional radio resources.

In some embodiments, one or more additional eNBs, e.g., eNB 112, may be employed, e.g., in a HetNet configuration. In some embodiments, the eNBs of a NtNet may have different power and / or access classes. For example, in the eNB 112 may be a relatively low-power base station, e.g., a pico eNB and / or femto eNB.

ENB 112 may have a Pcell and one or more Scell (s) to eNB 104. For example, if the eNB 104 has a CC_0 for its Pc and its CC_1 for its Scell.

The UE 108 may include the receiver module 120, the decoder module 124, the scheduling module 128, and the transmitter module 132 coupled with one other at least as shown. 120. Briefly, the decoder module 120. Briefly, the decoder module 124 may be used as a decoder module. identify transmissions, within the UE 108. The receiver module 120 and transmitter module 132 of the UE 108.

The UE 108 may include any number of suitable antennas. In various embodiments, the UE 108 may include at least a number of antennas as a number of antimicrobials. The number of simultaneous spatial layers or streams may also be mentioned.

One or more of the antennas 132 may be alternatively used as transmitting or receiving antennas. Alternatively, or additionally, one or more of the antennas may be dedicated to an antenna or dedicated transmit antenna. ENB 104 may include receiver module 136, scheduling module 140, encoder module 144, and transmitter module 148 coupled with one other at least as shown. 148 of the eNB 104. The transponder module and the transducer module. eNB 104 may include any number of suitable antennas. In some embodiments, the eNB 104 may include at least many antennas as a number of simultaneous transmission streams to the UE. One or more of the antennas 152 may be alternately used as transmit or receive antennas. Alternatively, or additionally, one or more of the antennas may be dedicated to an antenna or dedicated transmit antenna.

The cross-carrier scheduling of a physical downlink shared channel (PDSCH), downlink control information (DCI) transmitted in. the Pcell may provide downlink grant information. The downlink grant information may be a reference to the UE 108 through the corresponding serving cell. The DCI may include a carrier indication field (CIF).

Conventionally, cross-carrier scheduling is restricted to downlink grant information in the DCI. For example, DCI transmitted in subframe 1 would apply only to subframe 1, though it could be any serving cell.

Various embodiments provide for multi-subframe cross-carrier (MSCC) scheduling on PDSCH. This is a subset of the first subframe of the subframe. The MSCC described can be used with CCs having different TDD UL / DL configuration. In some embodiments, this MSCC scheduling may not be supported by DCI detection performance degradation. This may be done in the form of a sub-grammar.

The MSCC scheduling may include predetermined subframe pairings (x, y) in each half radio frame. The pairings may include a first pairing (0, 3) and a second pairing (1.4). These particular pairings may provide equal processing latency between the paired subframes. However, other embodiments may include other pairings.

Generally, the predetermined subframe pairings may provide the option of DCI, and in particular, in the subframe of the subcellramine of the Scell. In some embodiments, the subframe pairing may not be the only TDD UL / DL configurations of the CCS preventive transmission of DL grant information in the same subframe of the subframe. the Pcell.

Embodiments provide that if the Pcell subframe, then the DCI for subframe will be transmitted at Pcell subframe y. However, if the Pcell subframe is an UL subframe, then the DCI for the subframe is the Ptw subframe of the cell. Depicted in Figures 2 (a) - 2 (c).

Figure 2 (a) illustrates a scenario in which the Pcell has the TDD configuration 0 with subframe 0 being a sublink subframe (D), subframe 1 being a special subframe (S), and subframes 2-4 being uplink subframes ( U). The TDD configurations may be defined by table 1 below.

Table 1

The special subframe may include three fields: downlink pilot time slot (DwPTS), which may include the DCI, guard period (GP), and uplink pilot time slot (UpPTS).

The Scell of Figure 2 (a) is TDD configuration 1 with subframes 0 and 4 being downlink subframes, and subframes 2 and 3 being uplink subframes.

In some embodiments, subframe 0 of the Pcell may include DCI that identifies a downlink resource in subframe 0 of the Scell. (0, 3) is not required DL grant information.

Subframe 1 of the Pcell may include DCI that identifies a downlink resource in the subframe 1 of the Scell. Subframe pairing (1,4) may be implemented in this case, because the subframe y of the Pcell, i.e., subframe 4, is an uplink subframe.

Figure 2 (b) illustrates the scenario in which the Pcell has the TDD configuration 0 with subframe 0 being a sublink subframe, subframe 1 being a special subframe, and subframes 2-4 being uplink subframes. The Scell has a TDD configuration 2 with subframes of 0.3, and 4 being a downlink subframe, being a special subframe, and being an uplink subframe.

Subframe 0 of the Pcell may include DCI that identifies a downlink resource in subframe 0 and / or subframe 3 of the Scell. The subframe pairing (0, 3) may be implemented in the subframe y of the Pcell, i.e., subframe 3, is an uplink subframe. Subframe 3 of the Scell is a downlink subframe and may therefore receive a DL grant.

Subframe 1 of the Pcell may include DCI that identifies a downlink resource in a subframe 1 and / or subframe 4 of the Scell. The subframe pairing (1,4) may be implemented in the subframe y of the Pcell, i.e., subframe 4, is an uplink subframe.

Figure 2 (c) illustrates the scenario in which the Pcell has a TDD configuration 1 with subframes 0 and 4 being a downlink subframes, and a subframe being 2 and 3 being uplink subframes. The Scell has a TDD configuration 2 with subframes 0, 3, and 4 being a downlink subframes, being a special subframe, and subframe 2 being an uplink subframe.

Subframe 0 of the Pcell may include DCI that identifies a downlink resource in subframe 0 and / or subframe 3 of the Scell. The subframe pairing (0, 3) may be implemented in the case of the subframe y of the Pcell, i.e., subframe 3, is an uplink subframe and subframe 3 of the Scell is a downlink subframe.

Subframe 1 of the Pcell may include DCI that identifies a downlink resource in a subframe 1. The subframe pairing (1,4) may not be implemented in the case of the subframe y of the Pcell, ie, subframe 4, also a downlink subframe. Therefore, subframe 4 of the Pcell may include DCI for subframe 4 of the Scell.

MSCC scheduling may be facilitated by the use of MSCC table 300 shown in Figure 3. MSCC table 300 may include mapping information for 3-bit CIF values and carrier aggregation levels as shown. The values within MSCC table 300 include the assigned CC, eg, CC_0, CC_1, CC_2, or CC_3, and subframe pairing index, eg, 0 and / or 1.

If DCI includes a CIF value of Ό00, 'the DCI information may pertain to the Pcell, i.e., CC_0. If DCI includes a CIF value of Ό01, 'the DCI information may be the first subframe of the subframe pair of the Scell, CC_1. For example, with reference to Figure 2 (b), if DCI was transmitted in subframe 0 of the Pcell and included in the CIF value of Ό01; If the DCI was transmitted in the subframe 1, then the downlink grant would be the same.

If DCI includes a CIF value of Ό10, 'the DCI information may be the second subframe of the subframe pair of the Scell, CC_1. For example, with reference to Figure 2 (b), if DCI was transmitted in subframe 0 of the Pcell and included in the CIF value of Ό10; If the DCI was transmitted in the subframe 1, the downlink grant is the same CIF value, then the downlink grant is the same.

If DCI includes a CIF value of Ό1T and the CA level is either two or three, the DCI information may be the first and second subframes of the Scell, CC_1. For example, with reference to Figure 2 (b), if DCI transmitted in subframe 0 of the Pt and included in the CIF value of Ό11, then the downlink grant information would be 0 and 3 of the Scell.

If DCI includes a CIF value of Ό1T and the CA level, or the DCI information may be the first subframe of the subframe pair of a second Scell, CC_2. The remaining mapping information may be interpreted in similar manners.

The CIF in MSCC table 300 is a 3-bit value in order to be compatible with existing 3-bit CIF fields of DCI in LTE REL 10. it is sufficient to establish a CC / subframe index; In some embodiments, CIF may be represented by more or less than 3 bits. CIF is also considered to be a CIF.

The value selected to be included in a particular table may be the particular Scell priority scheme. In general, the tables may reflect a bias towards lower-level scales. This is due to the use of a lower frequency band for the first Scell. However, different Scells in different manners.

Tables 404 and 408 of Figure 4 reflect various scell priority schemes, which illustrate some of the various uses in the design of tables.

Table 404 also provides priority. Therefore, each possible subframe pairing index, e.g., O ',' T, and '0.1' is provided for each CA level. If the CA level is four or greater, then the scheduling of the subframes of the pair is not supported for the higher CCs, e.g., CC_2, CC_3 and CC_4. Additionally, when the CA level is not the same as CC_3 or CC_4.

Table 408 provides a Scell priority scheme for the first and second level. If the CA level is four, then only the value of the subframe pair is supported for CC_3. If the CA level is five, then the two subframe scheduling is not supported for CC_2.

[0047] Figure 5 illustrates an MSCC scheduling of a frame in which a cell is configured for communication in accordancewith some embodiments. The radio frame is a 10 ms radio frame with PDSCH transmissions on subframes 0 and 6 of the Pcell and subframes 1.3, 4, 5, 6, and 8 of the Scell.
