Description

A kind of determination method and apparatus of PDSCH CC state of activation

Technical field

The present invention relates to communication technical field, particularly relate to a kind of determination method and apparatus of PDSCH CC state of activation.

Background technology

LTE (Long Term Evolution, Long Term Evolution) be 3G (3rd Generation, third generation digital communication) evolution, LTE improves and enhances the aerial access technology of 3G, adopt OFDM (Orthogonal Frequency Division Multiplexing, OFDM) and MIMO (Multiple Input Multiple Output, multiple-input and multiple-output) as the standard of this LTE wireless network evolution.Wherein, LTE system and before wireless communication system in, only have a carrier wave in a community, as shown in Figure 1, the maximum bandwidth in LTE system is 20MHz; And under the spectral bandwidth of 20MHz, LTE can provide the peak rate of descending 100Mbit/s and up 50Mbit/s, improve the performance of Cell Edge User, and improve cell capacity and reduce system delay.In addition, in LTE system, UE (User Equipment, subscriber equipment) can only work under a carrier wave simultaneously, and a LTE community only has a carrier wave, and each LTE community is identified by a unique in a network number.

And increasing rapidly along with number of users of mobile terminal amount, the volume of business of terminal use exponentially increases, in order to meet the business demand of terminal use continued to increase, need to provide larger bandwidth to meet the more peak rates required for the business of terminal use and application.At LTE-A (LTE-Advanced, senior LTE) in system, the peak rate of system has huge raising than LTE, requirement reaches descending 1Gbps, up 500Mbps, now, if the carrier wave that only uses a maximum bandwidth to be 20MHz, it is obviously the requirement that cannot reach peak rate.Therefore, lte-a system needs the operable bandwidth of terminal extension user, introduce CA (Carrier Aggregation thus, carrier aggregation) technology, by the multiple continuous or discrete carrier aggregation under same eNB (or base station) together (community under different e NB or can not be polymerized between member carrier), be UE service, to provide the speed needed for UE simultaneously.Wherein, the above-mentioned carrier wave condensed together is also called CC (Component Carrier, member carrier), and each community can be a member carrier, and the community (member carrier) under different e NB can not be polymerized.In addition, in order to ensure that the UE under LTE can work under the carrier wave of each polymerization, during requirement carrier aggregation, each carrier wave is maximum is no more than 20MHz, as shown in Figure 2, for the carrier aggregation technology schematic diagram under a kind of LTE-A, can find out, under the base station of LTE-A, have 4 carrier waves that can be polymerized, transfer of data can be carried out, to improve throughput of system with UE in base station simultaneously on 4 carrier waves.

In LTE system, down physical channel comprises: PDSCH (Physical Downlink SharedChannel, physical layer shared channel), PBCH (Physical Broadcast Channel, physical layer broadcast channel), PMCH (Physical Multicast Channel, physical layer Multicast Channel), PCFICH (PhysicalControl Format Indicator Channel, Physical layer control information format indication channel), PDCCH (Physical Downlink Control Channel, physical layer control channel), PHICH (PhysicalHybrid ARQ Indicator Channel, physical layer HARQ feedback indicating channel).

In above-mentioned down physical channel, PDCCH channel is mainly used in transmitting the dispatch for up-downgoing, PDSCH channel is mainly used in downlink data transmission, in the ordinary course of things, existing PDCCH channel on a member carrier, also have PDSCH channel, both are divided by time domain, PDCCH and PDSCH channel schematic diagram as shown in Figure 3.

In LTE system, owing to only having a member carrier, then the PDCCH on a CC can only dispatch the PDSCH on this CC.And for multicarrier system, following situation can be there is: the PDCCH on a CC is contaminated (such as, serious interference on this PDCCH channel), now, can in the upper configuration of other DL (descending) CC across carrier scheduling function, the PDCCH namely on a CC can dispatch the PDSCH on multiple DL CC.It should be noted that synchronization DLPDSCH CC can only be dispatched by a PDCCHCC, this scheduling relation is based on the semi-static configuration of CC.

The scheduling relation of PDCCH and PDSCH as shown in Figure 4, for PDCCH, contaminated or non-serviceable DL CC, can be called PDSCH-only CC, in the diagram, PDSCH on CC2 can not be dispatched by the PDCCH on CC2, but can be dispatched by the PDCCH on CC1.

In multi-carrier systems, the maximum rate sum of all business that base station can be asked according to UE (User Equipment, subscriber equipment) is that UE configures an operating carriers set, is called for short configuration CC set.In the CC set configured to UE, multicarrier system can select a CC as PCC (the primary component carrier of this UE based on UE, main carrier), and other CC configured in this carrier set is the SCC (secondary component carrier, auxiliary carrier wave) of this UE.It should be noted that the PCC of different UEs may be different.

In addition, in lte-a system, the PCC of UE does not allow to activate or deexcitation, it is activate that PCC gives tacit consent to always, after configuring the SCC configuration in CC set, then acquiescence is deexcitation, if need to use these SCC, needs first to carry out carrier activation operation to SCC.Business due to UE may have fluctuation and sudden, namely in certain period, traffic carrying capacity is little, and traffic carrying capacity is very large in certain period, therefore, when UE traffic carrying capacity is fewer, in order to better economize on electricity, need to carry out carrier activation or deactivating operation to the CC in configuration CC set according to the service conditions that UE is current further, and for the carrier wave of deexcitation, UE does not need to monitor PDCCH again, thus can reach better power savings.

In prior art, specify to carry out activation/deactivation operation to the carrier wave in multicarrier system, explicit way and implicit can have been adopted.Wherein, namely explicit activation/deactivation uses carrier activation/deexcitation MAC CE (MAC control element, media access control layer control unit), MAC CE uses bitmap (bit mapping) mode, the corresponding CC of each bit (bit) is (because PCC can not be activated/deexcitation, bit corresponding separately can be had to PCC, can not have) yet, if certain bit is set to 0, then represent the CC that deexcitation is corresponding, if certain bit is set to 1, then represents and activate corresponding CC.Namely implicit expression deexcitation utilizes deactivation timer (packet data inactivity timer), if deactivation timer is overtime, then and the CC that deexcitation is corresponding.It should be noted that carrier activation/deexcitation all for descending SCC, current up CC does not have carrier activation/deactivating operation.

Realizing in process of the present invention, inventor finds at least there is following problem in prior art:

In the process of carrier wave deexcitation, when not having carrier wave deexcitation in current agreement, how PDCCH CC and PDSCH CC carries out mutual description.If the DL CC of a scheduling PDSCH-only is all deactivated, and this PDSCH CC of not deexcitation, so will cause unnecessary expense electricity, particularly when PDSCH-only CC and other PDCCH CC does not use a transceiver, take electricity more serious.

Visible, the method that the application of the invention provides, determines the state of activation of PDSCH CC according to the state of activation of PDCCH CC, realizes PDCCH CC and PDSCH CC carries out mutual process, and can more effectively economize on electricity.

In order to the technical scheme that the explanation embodiment of the present invention clearly provides, below the defining method of the PDSCH CC state of activation that the embodiment of the present invention proposes is described in detail.In embodiments of the present invention; network equipment includes but not limited to eNB (evolved Node B; evolved base station), Relay etc.; it should be noted that; this network equipment is not limited to the said equipment; all equipment being positioned at network side, all within scope, for convenience of description, is described for base station in the embodiment of the present invention.

In the embodiment of the present invention, the impact of PDCCH CC state of activation on PDSCH CC state of activation is specially: if all PDCCH CC that can dispatch a PDSCH CC are deactivated, then this PDSCH CC also needs to be deactivated.Clear for convenience of description, be described for PDSCH-only CC.

In the embodiment of the present invention, according to the difference of carrier activation/deexcitation MAC CE form, following several execution mode can be had.

The first situation: have the corresponding PDSCH-only CC in independently bit position in MAC CE

Mode one: all PDCCH CC of PDSCH-only CC can be dispatched in deexcitation while, this PDSCH-only CC of deexcitation.

In base station side: when base station needs to send carrier activation/deexcitation MAC CE, the corresponding bit position of all DL PDCCH CC judging to dispatch this PDSCH-only CC is needed whether to be all set to deexcitation instruction (such as, when representing that deexcitation indicates when bit position is 0, then need to judge whether the corresponding bit position of all DL PDCCHCC is all set to 0), if the corresponding bit position of all DLPDCCH CC that can dispatch PDSCH-only CC is all set to deexcitation instruction, the bit position that then this PDSCH-only CC is corresponding also needs to be set to deexcitation instruction (such as, be 0 by this bit position).

In user equipment side: after UE receives carrier activation/deexcitation MAC CE, if there is PDSCH-only CC and the corresponding equal deexcitation in bit position of all PDCCH CC can dispatching this PDSCH-only CC (such as, bit position is 0), then UE needs to obtain bit position corresponding to PDSCH-only CC.If the corresponding bit position of this PDSCH-only CC is deexcitation instruction), then need this PDSCH-only CC deexcitation; If the corresponding bit position of this PDSCH-only CC is for activating instruction (such as, being set to 1), then UE judgement occurs abnormal, abandons this MAC PDU and ignore this MAC CE to indicate, and does not do activation/deactivation operation to all carrier waves.

Mode two: UE determines whether deexcitation PDSCH CC by multilevel iudge

In base station side: will need the PDCCH CC deexcitation of deexcitation, and do not make a decision PDSCH CC and process, namely the corresponding bit position of PDSCH CC may be set to and activate instruction or deexcitation instruction.

In user equipment side: after mode (1) UE receives carrier activation/deexcitation MAC CE, if there is PDSCH-only CC, the corresponding bit position of all DL PDCCHCC judging to dispatch this PDSCH-only CC is then needed whether to be all set to deexcitation instruction, if the corresponding bit position of all DL PDCCH CC that can dispatch this PDSCH-only CC is all set to deexcitation instruction, the bit position that then no matter this PDSCH-only CC is corresponding is deexcitation instruction or activates instruction, and UE needs this PDSCH-onlyCC of deexcitation.After mode (2) UE receives carrier activation/deexcitation MAC CE, no matter whether there is PDSCH-only CC, all carry out carrier activation/deactivating operation according to the instruction of carrier activation/deexcitation MAC CE; And if now there is PDSCH-only CC and still for state of activation, then need by the final deexcitation of deactivation timer.

The second situation: do not have the independently corresponding PDSCH-only CC in bit position in MAC CE.Now, UE needs to determine whether deexcitation PDSCH CC by multilevel iudge

In base station side: will the PDCCH CC deexcitation of deexcitation be needed, and do not have corresponding MAC CE bit position, therefore not need to consider PDSCH-only CC due to PDSCH-only CC.

In user equipment side: after mode (1) UE receives carrier activation/deexcitation MAC CE, if there is PDSCH-only CC, the corresponding bit position of all DL PDCCHCC judging to dispatch this PDSCH-only CC is then needed whether to be all set to deexcitation instruction, if the corresponding bit position of all DL PDCCH CC that can dispatch this PDSCH-only CC is all set to deexcitation instruction, UE needs this PDSCH-only CC of deexcitation.After mode (2) UE receives carrier activation/deexcitation MAC CE, no matter whether there is PDSCH-only CC, all carry out carrier activation/deactivating operation according to the instruction of carrier activation/deexcitation MAC CE; And if now there is PDSCH-only CC and still for state of activation, then need by the final deexcitation of deactivation timer.

It should be noted that in the embodiment of the present invention, it is one or any several that the operation after CC is deactivated at least comprises in following operation: stop monitoring the PDCCH on this DL CC; If this CC there is deexcitation timer run, then stop this timer; Stop the PDSCH transmission on this DL CC (comprise and just pass and/or retransmit); UL scheduling (comprise and just pass and/or retransmit) before ignoring on this DL CC; Stop on UL CC and send out CQI information corresponding to this DL CC of feedback; If certain UL CC can only by this DL

CC dispatches, then corresponding UL CC stops SRS and/or PHR send.

In addition, bitmap mode can also be adopted in carrier activation/deexcitation MAC CE, and when adopting bitmap mode, the mapping relations of bit and CC can at least adopt in following several mode any one.

(1) map according to the CC numbering of cell level, all CC supported in Ji Dui community carry out Unified number, the corresponding CC of each bit of carrier activation/deexcitation MAC CE.

(2) the CC numbering based on UE rank maps, the CC Unified number that namely can be polymerized UE or be polymerized, the corresponding CC of each bit of carrier activation/deexcitation MAC CE.

(3) map according to the frequency of CC, namely according to CC frequency order from low to high or from high to low, the corresponding CC of each bit of carrier activation/deexcitation MAC CE.

(4) corresponding relation of each bit in signaling CC and carrier activation/deexcitation MAC CE is adopted.

It should be noted that concerning with PCC, because PCC can not be activated/deexcitation, independently bit can be had corresponding with this PCC, also can independently bit be not corresponding with this PCC.
