Description
Technical Field
The present invention relates to a multi-flow-high speed downlink shared packet access technology, and in particular, to a hybrid automatic repeat request (HARQ) configuration method and apparatus for an auxiliary cell.
Background
The high-speed downlink shared packet access (HSDPA) and the evolution function thereof, such as Double Carrier (DC), double-frequency band-double carrier (DB-DC), Multiple Input Multiple Output (MIMO) and other functions, greatly improve the peak rate and throughput of the network, and enhance and improve the network experience of users. However, the DC technology has a strict requirement on network frequency point resources of operators, and thus limits the application of the DC; and, because the HSDPA does not have a soft handover function, the performance of the HSDPA user is poor when the HSDPA user is located at the edge of a cell, and when the HSDPA user is located in a handover area, if HSDPA resources of a plurality of cells can be simultaneously utilized, not only can the experience of the user be greatly improved, but also the utilization rate of network resources can be further improved, and the average throughput of the network can be improved. For this reason, 3GPP introduced multi-flow-high speed downlink shared packet access (MF-HSDPA) technology in release R11.
The MF-HSDPA technology refers to that two high-speed downlink shared channels (HS-DSCH) positioned at the same frequency point simultaneously schedule different data blocks for the same MF-HSDPA user. A user using multiflow technology can receive HS-DSCH for at most 4 cells simultaneously, and each cell is defined as follows according to its functional role: the serving high-speed shared downlink channel cell (serving HS-DSCHCell), the auxiliary serving high-speed shared downlink channel cell (assisting serving HS-DSCHCell), the auxiliary serving high-speed shared downlink channel cell (serving high-speed shared HS-DSCHCell), and the auxiliary serving high-speed shared downlink channel cell (assisting serving high-speed shared HS-DSCHCell). Wherein servingHS-DSCHCell and subcontrondervingHS-DSCHCell are dual carrier cells, and AssisticingservingHS-DSCHCell and AssisticingsubcontrorvicengHS-DSCHCell are dual carrier cells; the AssisingservingHS-DSCHCell has the same frequency point as the servingHS-DSCHCell, and the AssisingsedondrynervingHS-DSCHCell has the same frequency point as the seconodrynervingHS-DSCHCell. Two HS-DSCH on the same frequency point may be located in the same node b (NodeB) or different nodebs, i.e. corresponding to two offloading modes of MF-HSDPA: intra-NodeB (intra-NodeB) mode and inter-NodeB mode. For the intra-NodeB mode, the protocol model is shown in fig. 1, and the serving rnc (srnc) includes: radio link control layer (RLC), dedicated channel medium access control layer (MAC-d), high speed shared channel frame protocol layer (HS-DSCHFP), layer two (L2), layer one (L1). The NodeB includes: the system comprises a high-speed downlink shared channel enhanced media access control (MAC-ehs) entity, HS-DSCHFP, L2 and L1, wherein each cell has a physical channel (PHY), downlink data distribution is positioned in the MAC-ehs entity, one MAC-ehs entity is shared during downlink data transmission, the MAC-ehs entity supports 4 HS-DSCH, and each HS-DSCH has respective corresponding uplink and downlink signaling and HARQ entity. And the UE side is also a MAC entity and receives data sent by physical channels of different cells. For inter-NodeB mode, the protocol model is shown in fig. 2, and the SRNC includes: RLC, MAC-d, HS-DSCHFP, L2, L1. Each NodeB includes: MAC-ehs entity, HS-DSCHFP, L2, L1, each cell has a physical channel, the downlink data distribution is located in RLC layer, two MAC-ehs entities are used for data transmission, each MAC-ehs entity supports two HS-DSCH, each HS-DSCH has its own corresponding uplink and downlink signaling and HARQ entity; for the UE side, there are two MAC entities, which respectively receive data sent by physical channels of different cells.
MF-HSDPA is used as an evolution function of HSDPA, and in order to reduce time delay and increase the data retransmission rate, the HARQ technology in HSDPA is still adopted. HARQ means that the receiving side stores the received data and requests the transmitting side to retransmit the data when decoding fails, and the receiving side combines the retransmitted data with the previously received data (if the data cannot be demodulated correctly, the previous data and the next data need to be combined to realize a macro diversity effect). The HARQ technique can improve system performance, flexibly adjust the rate of valid symbols, and compensate for bit errors due to link adaptation. In order to save data, the receiving side needs to set the HARQ memory area, and for User Equipment (UE), in order to save cost, the memory is invaluable, and the HARQ memory area needs to be reasonably set according to system configuration. For the inter-NodeB mode, the UE has two MAC-ehs entities, wherein a serving HS-DSCHcell and a serving HS-DSCHcell belong to one NodeB and share one MAC-ehs entity, and an assisting serving HS-DSCHcell and an assisting serving HS-DSCHcell (hereinafter referred to as an auxiliary cell) belong to one NodeB and share one MAC-ehs entity.
