Abstract
The embodiment of the invention discloses a method and device for processing power headroom reporting (PHR). The method comprises the steps of initiating a contention-based uplink data transmission while user equipment satisfies a condition of using contention-based uplink transmission resources; and forbidding the user equipment from transmitting the PHR by using the contention-based uplink transmission resources in the contention-based uplink data transmission process, or forbidding the triggering of the PHR if no dedicated uplink transmission resources is received in the contention-based uplink data transmission process. By using the invention, state conversion delay can be assured and user experience can be enhanced.
Description
Technical field
The present invention relates to the mobile communication technology field, particularly relate to processing method and the device of a kind of power headroom reporting PHR.
Background technology
LTE (Long Term Evolution, Long Term Evolution) system is 3G (3rd Generation, the third generation communication technology) evolution technology is all progressive to some extent at aspects such as systematic function requirement, network design scene, the network architecture and business support abilities with respect to 3G technology.
In the LTE system, for to the current transmitting power of base station equipment feedback user equipment, so that base station equipment configuration in time and scheduling, subscriber equipment need report PH (PowerHeadroom to base station equipment, power headroom) information, this reports process to be called as PHR (Power HeadroomReporting, power headroom reporting), and base station equipment is no more than the PH of user equipment to report to the authorization power of user equipment allocation.Particularly, the value of PH is the difference between PUSCH (Physical Uplink Shared Channel, the Physical Uplink Shared Channel) transmitting power estimated of the maximum transmission power of subscriber equipment and subscriber equipment, can calculate according to following formula:
PH＝P
MAX-P
PUSCH；
Wherein, PH is a power headroom; P
MAXMaximum transmission power for subscriber equipment; P
PUSCHPower for the PUSCH that carries PHR information uses is carried in dispatching command by eNB (Evolved Node B, evolved Node B).
The purpose of PHR is the difference notice eNB between UL-SCH (Up Link-Synchronization Channel, the uplink synchronisation channel) channel emission power of the maximum transmission power of subscriber equipment and subscriber equipment estimation.The relevant parameter of PHR comprises the periodically path loss running parameter dl-PathlossChang of cycle, the length of forbidding PHR timer prohibitPHR-Timer and the triggering PHR of PHR timer periodicPHR-Timer, above-mentioned parameter is by RRC (Radio resource control, Radio Resource control) layer configuration.
Corresponding with the relevant parameter of PHR, the trigger condition of PHR comprises:
1, subscriber equipment has ascending resource to use, and prohibitPHR-Timer is overtime, and a nearest PHR path loss changes above dl-PathlossChange dB;
2, periodicPHR-Timer is overtime;
3, high level is first disposes PHR or PHR is carried out reprovision.
When satisfying any one of above-mentioned condition, subscriber equipment triggers PHR, at first notifies physical layer to calculate pH value; Subsequently, notice Multiplexing and Assembly process generates PHR MAC (MediaAccess Control, media interviews control) CE (Control Element, control unit); Restart/restart periodicPHR-Timer and prohibitPHR-Timer; At last, cancel the PHR of all triggerings.
If UE (User Equipment, subscriber equipment) has up available resources,, then carry out PHR and report according to priority of logical channels in case trigger PHR.If the current ascending resource that distributes for UE can hold a PHR MAC CE, then report process to comprise: the notice physical layer is calculated pH value; Notice Multiplexing and Assembly process generates PHR MAC CE; Start/restart periodicPHR-Timer; Start/restart prohibitPHR-Timer; Cancel the PHR of all triggerings.
The form that reports of PHR comprises 1 MAC head and 1 MAC CE, respectively as depicted in figs. 1 and 2.
Wherein, LCID (Logical Channel ID, Logic Channel Identifier) reports for PHR for being used to identify the logical channel number of corresponding load part, and LCID is used to identify corresponding load and partly is PHR; E is an extended bit, and being used to indicate next byte is MAC head or MAC load; R is a reserved bit; PH is a power headroom.
Yet in the LTE system that uses above-mentioned PHR mechanism, a sub-district has only a carrier wave, and this sub-district is called as single-carrier cell.According to the LTE system protocol, the maximum bandwidth that allows to transmit in single-carrier cell is 20MHz, and bandwidth is lower, can not satisfy the more and more higher transmission rate requirements of user fully.Based on above-mentioned situation, communication technical field has proposed LTE-A (LTE-Advanced, senior Long Term Evolution) system, and the peak rate of this system improves a lot than LTE, and downstream rate reaches 1Gbps, and upstream rate reaches 500Mbps.Simultaneously, LTE-A system and LTE system also have good compatibility.
In order to support shorter conversion time delay and to get rid of DRX (Discontinuous Reception from resting state (Dormant) to state of activation (Active), discontinuous reception) influence in cycle, to improve user experience, 3GPP LTE-A proposition is reduced to UE 10 milliseconds target from the change-over time that has upstream data to send to uplink, further improve existing state conversion process, and introduce based on transmitting uplink data (the Contention based transmission) mode of competing, when UE is current when not having special-purpose resource, can be allowed to transmit ascending data on the ascending resource of competition.
Particularly, base station notice UE is based on the uplink basic configuration information of competition, and this information comprises scheduling identification CB-RNTI (Contention Based-Radio Network Temporary Identity is based on the Radio Network Temporary Identifier of competition); UE receives and stores the uplink basic configuration information based on competition; ENB dispatches competitive resource; The mandate of UE decoding scheduling is also encoded the upstream data after the Uplink Shared Channel transfer encoding to upstream data.
Based on above-mentioned flow process, the estimation of the optimum delay of each several part, as shown in table 2:
Table 2 CB transmission optimum delay estimating table
| Step | Describe | Time [millisecond] |
| 1 | Wait for the average delay of subframe head | 0.5 |
| 2 | UE obtains |
1 |
| 3 | UE processing delay (decoding scheduling mandate+L1 encodes to upstream data) | 3 |
| 4 | Transmit ascending |
1 |
| Time delay altogether | 5.5 |
The inventor is in realizing process of the present invention, and there are the following problems at least to find prior art:
After UE triggered PHR, the PHR information priority, reported to finish PHR on up available resources in Data-carrying.When but UE only has the up CB resource time spent, also need cause PHR MAC CE to seize the user data resource, time delay shortening and user experience are caused adverse effect at CB transmitted over resources PHRMAC CE.
If at CB transmitted over resources PHR MAC CE, eNB can not have resource allocation accurately to competition transmission, and the calculating of PHR is based on that power that eNB distributes to UE carries out, and therefore, PHR can't calculate.Even the power calculation PHR that UE assesses out by open loop power control, this PHR is to eNB reference significance not how.In addition,, might cause UE in time not report PHR, make eNB not carry out correct power control non-competing transmission if the PHR of CB resource is reported the reference point that reports as subsequent triggers PHR.
Summary of the invention
