Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of an information processing method according to an embodiment of the present invention, where this embodiment is applicable to a case where a receiving node performs data communication with a sending node, for example, a point-to-multipoint service, and the method may be executed by an information processing apparatus according to an embodiment of the present invention, where the apparatus may be implemented in a software or hardware manner, and the apparatus is integrated in the sending node, and an execution main body of this embodiment is the sending node integrated with the information processing apparatus according to an embodiment of the present invention, as shown in fig. 1, specifically including:
s101, a sending node acquires the total receiving power of each uplink resource in an uplink resource group through the uplink resource group used when detecting the receiving node feedback information in the service group, wherein the service group comprises at least one receiving node.
The sending node may be, but is not limited to, a terminal or a base station, and the receiving node may be, but is not limited to, a terminal. The base station may be, but is not limited to, a base station in a 2G, 3G, 4G network. The terminal may be, but is not limited to, a mobile terminal, a tablet computer, and a fixed terminal. The number of the receiving nodes can be one or more, and the number of the sending nodes is one. When there are multiple receiving nodes, in order to further reduce the detection burden of subsequent sending nodes, multiple receiving nodes receiving the same service share one uplink resource group, that is, multiple receiving nodes all feed back information through the uplink resources in the shared uplink resource group. For example, for a point-to-multipoint service, all receiving nodes in the service group share one uplink resource group, and a sending node performs detection in the same uplink resource group during detection, so that the burden of the receiving node can be effectively reduced.
The feedback information may be, but is not limited to, link state information. The link state information includes, but is not limited to, at least one of: channel Quality Indicator (CQI), Signal to Interference plus Noise Ratio (SINR), modulation and coding scheme, and Channel space information. The channel spatial information includes, but is not limited to, at least one of: rank Indicator (RI), Precoding Matrix Indicator (PMI), and elevation Indicator (AI). The HARQ information and the link state information are reference factors for subsequently determining the modulation and coding mode of the service group.
The uplink resource is a resource for information feedback to the sending node, and is preferably an uplink synchronization resource, such as a Pseudo-Noise (PN) sequence or a chirp (Zadoff-Chu, ZC) sequence.
S102, the sending node determines the number of receiving nodes which feed back information through the uplink resources according to the total receiving power and the target receiving power.
Specifically, the sending node may determine the number of receiving nodes that feed back information through the uplink resource according to the total received power and the target received power in the following two ways:
in a first mode, the sending node calculates the number of receiving nodes which receive the uplink resource feedback information by using the following formula one:
where N is the number of receiving nodes, ceil () is rounded, PrxAs total received power, PtargetA target received power;
in a second mode, the sending node calculates the number of receiving nodes which receive the uplink resource feedback information by using the following formula two:
N＝ceil[Prx(W)/Ptarget(W)]
where N is the number of receiving nodes, ceil () is rounded, PrxAs total received power, PtargetIs the target received power.
In this embodiment, the sending node determines the number of receiving nodes that feed back information through the uplink resource according to the total receiving power and the target receiving power, so that the sending node can adopt an appropriate modulation and coding mode according to the number of receiving nodes when transmitting data for the receiving nodes in the service group in the subsequent process, and the transmission efficiency of the service data can be improved.
On the basis of the above embodiment, the method further includes:
and the sending node sends target receiving power to the receiving node so that the receiving node determines corresponding transmitting power according to the target receiving power.
Specifically, in order to keep the receiving power of each receiving node to the sending node consistent so that the sending node can count the number of receiving nodes on the uplink resource, the sending node sends target receiving power to the receiving nodes so that the receiving nodes determine corresponding transmitting power according to the target receiving power, and the determined transmitting power is used for sending feedback information through the uplink resource.
On the basis of the above embodiment, to prevent the waste and saturation of uplink resources, the method further includes:
and the transmitting node sets a lower limit value and an upper limit value of the total received power for each uplink resource.
If the sending node determines that the total received power is greater than the total received power upper limit value, adding a new uplink resource to the uplink resource of which the total received power is greater than the total received power upper limit value at the next receiving moment until the total received power on each uplink resource is between the total received power lower limit value and the total received power upper limit value.
Specifically, the added uplink resource may be one uplink resource or one uplink resource group. And the sending node informs the receiving node of the increased uplink resource for the receiving node to use.
Or, if the sending node determines that the total received power is smaller than the lower limit of the total received power, reducing uplink resources for the receiving node at the next receiving moment until the total received power on each uplink resource is between the lower limit of the total received power and the upper limit of the total received power.
Specifically, the reduced uplink resource may be one uplink resource or one uplink resource group. And the sending node informs the receiving node of the increased uplink resource, and the receiving node does not use the decreased uplink resource feedback information any more. The reducing of the uplink resource may specifically be deleting the uplink resource, or releasing the uplink resource.
On the basis of the above embodiment, before the receiving node feeds back information to the sending node by using the uplink resource, the method further includes:
the sending node allocates an uplink resource group for a receiving node group, the receiving node group comprises at least one receiving node, and the uplink resource group comprises at least one uplink resource, so that the receiving node uses uplink resource feedback information in the uplink resource group.
On the basis of the above embodiment, the feedback information includes link state information, and the method further includes: and the transmitting node determines the modulation and coding mode of the service group according to the link state information and the number of the receiving nodes.
Specifically, the sending node determines link state information corresponding to the receiving nodes meeting the coverage rate requirement according to the number of the receiving nodes and the link state information; and determining the modulation and coding mode of the service group according to the corresponding link state information. For example, the link state information is CQI, if at the time point of TTI — N, 20 user equipments UE in the service group R1 feedback CQI through uplink resources in the uplink resource group, and if the base station detects each uplink resource in the uplink resource group, the base station obtains the following result: there are 1 UE feeding back CQI 2; there are 8 UEs feeding back CQI-3; there are 6 UEs feeding back CQI 4; there are 5 UEs feeding back CQI 10. The base station removes 5% of UE with poor CQI (the smaller the CQI value is, the worse the communication quality of the corresponding UE is) according to the coverage rate requirement of 95%, namely, the 1 UE with the CQI value of 2 is rankedExcept that the CQI satisfying the coverage requirement is selected among the remaining UEs as the CQI finally used for determining the modulation and coding scheme, which may be referred to as CQI herefeedbackAnd CQIfeedbackWhen the coverage rate requirement of 95% can be met when the CQI is 3, the CQI is usedfeedbackReferring to the mapping table shown in fig. 1B among CQI, MCS representing relative values of modulation and coding schemes, and modulation and coding schemes, CQI and CQI can be determinedfeedbackIf the MCS corresponding to 3 is 3, the modulation scheme of the service group is further determined to be QPSK and code rate 2/3 according to MCS 3.
In addition, the feedback information may further include Hybrid Automatic repeat request (HARQ) information. The HARQ information includes an acknowledgement character ACK or a non-acknowledgement character NACK. Correspondingly, the transmitting node determines the modulation and coding mode of the service group according to the corresponding link state information and HARQ information.
Specifically, the HARQ information of the sending node determines the corresponding outer ring factor, or determines the corresponding outer ring factor according to the HARQ information and the number of receiving nodes. For example, if the sending node determines that the HARQ feedback information is an acknowledgement character ACK, an outer loop ascending step length is added on the basis of the outer loop factor; and determining the modulation and coding mode of the service group according to the increased outer loop factor and the MCS corresponding to the finally determined link state information (for example, MCS in the above example is 3). Or, the sending node determines that the HARQ feedback information is a non-acknowledgement character NACK, and subtracts an outer loop decreasing step length on the basis of the outer loop factor; and the modulation and coding mode of the service group is determined according to the subtracted outer loop factor and the finally determined MCS corresponding to the link state information (for example, MCS in the above example is 3).
Or, determining the modulation and coding mode of the service group according to the corresponding link state information, the number of receiving nodes and the HARQ information. Specifically, the base station determines the CQI based on the methodfeedbackThen determining the CQIfeedbackCorresponding initialMCSfeedback. Further adjusting the outer ring factor according to the number of the receiving nodes, if the HARQ information fed back by the receiving nodes is NACK information and the number of the receiving nodes meets the requirement of the coverage rate, subtracting an outer ring descending step length on the basis of the outer ring factor, and according to the subtracted outer ring factor and MCSfeedbackAnd determining the modulation and coding mode of the service group.
The value range of the outer ring ascending step length is preferably but not limited to [0.01,1 ]; and/or, the value range of the outer ring descending step length is preferably but not limited to [0.01,5 ]. The ratio of the outer ring up step to the outer ring down step may be, but is not limited to, TargetBLER (1-TargetBLER).
In the embodiment, the number of the receiving nodes which feed back information through the uplink resource is determined by the sending node according to the total receiving power and the target receiving power, so that feasible support is provided for link adaptation of the cluster.
Example two
Fig. 2 is a flowchart of an information processing method according to a second embodiment of the present invention, where this embodiment is applicable to a case where a receiving node performs data communication with a sending node, for example, a point-to-point service or a point-to-multipoint service, and the method may be executed by an information processing apparatus according to a second embodiment of the present invention, where the apparatus may be implemented in a software or hardware manner, and the apparatus is integrated in the receiving node, and an execution main body of this embodiment is the receiving node into which the information processing apparatus according to the second embodiment of the present invention is integrated, as shown in fig. 2, specifically including:
s201, a receiving node determines transmitting power according to target receiving power sent by a sending node and path loss power reaching the sending node.
The receiving node may be, but is not limited to, a terminal. The transmitting node may be, but is not limited to being, a terminal or a base station. The base station may be, but is not limited to, a base station in a 2G, 3G, 4G network. The terminal may be, but is not limited to, a mobile terminal, a tablet computer, and a stationary terminal. Here, the number of the sending node is one, and the number of the receiving nodes may be one or more.
Specifically, the receiving node calculates the sum of the target received power and the path loss power, and uses the sum as the transmission power.
S202, the receiving node feeds back information to the sending node through the uplink resources in the uplink resource group by using the determined transmitting power, wherein the feedback information comprises link state information, so that the sending node determines the number of the receiving nodes according to the total receiving power and the target receiving power of the uplink resources, and determines the modulation and coding mode of the service group to which the receiving node belongs according to the link state information and the number of the receiving nodes.
The uplink resource group includes at least one uplink resource, where the uplink resource is a resource used for information feedback to the sending node, and is preferably an uplink synchronization resource, such as a PN sequence or a ZC sequence.
Wherein the feedback information is HARQ information or link state information. The link state information includes, but is not limited to, at least one of: CQI, SINR and modulation and coding scheme. The modulation scheme may be QPSK, 16QAM, 64QAM, etc., and the corresponding code rate may be, but is not limited to, 1/3, 2/3, 1/2, 4/5, etc. The channel spatial information includes, but is not limited to, at least one of: RI, PMI and AI. The HARQ information includes ACK information or NACK information. The determined number of receiving nodes, HARQ information, and link state information are all used to determine a modulation and coding scheme of the service group, which is specifically referred to the related description in the first embodiment, and is not described herein again.
When there are multiple receiving nodes, multiple receiving nodes receiving the same service may share one uplink resource group, that is, multiple receiving nodes all perform information feedback through uplink resources in the uplink resource group.
In this embodiment, the receiving node determines the transmission power according to the target receiving power sent by the sending node and the path loss power reaching the sending node, and feeds back information to the receiving node through the uplink resource in the uplink resource group by using the determined transmission power, so that the sending node determines the number of the receiving nodes according to the total receiving power and the target receiving power on the uplink resource, and when data is subsequently transmitted to the receiving nodes in the service group, an appropriate modulation and coding mode can be adopted according to the number of the receiving nodes, thereby improving the transmission efficiency of the service data.
On the basis of the above embodiment, in a situation where the sending node adds a new uplink resource to an uplink resource in the uplink resource group, the receiving node equally selects the uplink resource and the new uplink resource to feed back information to the receiving node by using the determined transmission power.
For example, the sending node determines the total received power on the uplink resource 2 through detection, and determines that the total received power is greater than the target received power, then the uplink resource 2 is expanded to 2 times the original uplink resource 2 for the UE in the service group with the feedback CQI of 2, that is, one uplink resource 2 is added, or one uplink resource group including the uplink resource 2 is added, and the UE is notified, and then the UE randomly selects the uplink resource 2 and the newly added uplink resource 2 to feed back the CQI of 2 according to a probability of 50%.
The first embodiment and the second embodiment are described in detail below through different communication scenarios corresponding to the third embodiment, the fourth embodiment, and the fifth embodiment.
EXAMPLE III
Fig. 3A is a flowchart of an information processing method according to a third embodiment of the present invention, where communication between a UE and a base station is used as a scenario in this embodiment, specifically, a point-to-multipoint service is performed, and the communication scenario is as follows: the base station divides the uplink resource groups for the point-to-multipoint CQI information feedback and determines a total received power lower limit Th1 and a total received power upper limit for each uplink resource in the groupTh 2. For each UE, the target received power of the feedback information of the base station is PTarget(dBm). With reference to fig. 3B, the method specifically includes:
at time S301 and TTI, the UE in the service group R1 selects the link state indicator obtained by the uplink resource feedback measurement in the uplink resource group.
For example, there are 1 user { UE in the service group R1kFeeding back CQI (channel quality indicator) 2 on uplink resource 2 in the uplink resource group, wherein the feedback transmission power is Ptxk(dBm)＝Ptarget+PLkWherein PL isk(dB) is UEkPath loss to the base station; within service group R1 are 14 users UEmFeeding back CQI (channel quality indicator) 3 on uplink resource 3 in a resource group, wherein the feedback transmission power is Ptxm(dBm)＝Ptarget+PLmWherein PL ism(dB) is UEmPath loss to the base station; within service group R1 are 5 users UEnFeedback CQI 10 on the uplink resource 10 in the resource group, the feedback transmitting power is Ptxn(dBm)＝Ptarget+PLnWherein PLn(dB) is UEnPath loss to the base station.
S302, the base station detects the total receiving power of the feedback information on each uplink resource in the uplink resource group, and determines the number of receiving nodes which pass through the feedback information of the uplink resources according to the total receiving power and the target receiving power.
For example, the base station detects that the total received power on the uplink resource 2 is Prx2(dBm), judging that Th1 is less than or equal to Prx2Th2 is not more than, and the number of UE which obtains feedback CQI 2 is calculated to be NumCQI2＝ceil(10((Prx2-PTarget)/10)) 1 is ═ 1; the base station detects that the total received power on the uplink resource 3 is Prx3(dBm), judging that Th1 is less than or equal to Prx3Th2 is not more than, and the number of the UE which obtains feedback CQI which is 3 is calculated to be NumCQI3＝ceil(10((Prx3-PTarget)/10)) 14; the base station detects that the total received power on the uplink resource 10 is Prx10(dBm), judging that Th1 is less than or equal to Prx10Th2 is not more than, and the number of UE which obtains feedback CQI is calculated to be 10 is NumCQI10＝ceil(10((Prx10-PTarget)/10))＝5。
S303, the base station determines the modulation and coding mode of the service group according to the CQI and the number of the receiving nodes.
The base station determines that 1 UE feeds back CQI which is 2 according to the CQI; there are 14 UEs feeding back CQI-3; there are 6 UEs feeding back CQI 4; there are 5 UEs feeding back CQI 10. The base station removes 5% of poor CQI according to the coverage requirement of 95% and the size of the CQI value, namely excluding 1 UE with the CQI value of 2, and selects the CQI meeting the coverage requirement from the rest UEs as the CQI finally used for determining the modulation and coding mode, wherein the CQI can be marked as the CQIfeedbackCQI is known by calculationfeedbackWhen the coverage rate requirement of 95% can be met when the CQI is 3, the CQI is usedfeedbackLooking up the mapping table among CQI, MCS and modulation and coding scheme as shown in FIG. 1B, the CQI can be determinedfeedbackAnd 3, taking the modulation and coding mode as the modulation and coding mode of the service group.
Example four
Fig. 4A is a flowchart of an information processing method according to a fourth embodiment of the present invention, and a difference between the present embodiment and the third embodiment is that, as shown in fig. 4B, an uplink resource is further added on the basis of an original uplink resource group, and in combination with fig. 4A, the method specifically includes:
s401, in TTI ═ N1At this point, the UEs in the service group R1 feedback the measured link state indication via the uplink resources in the uplink resource group.
