Description

Based on ascending transmission method and the device of competition

Technical field

The present invention relates to the communications field, in particular to a kind of (Contention based, referred to as CB) ascending transmission method based on competition and device.

Background technology

At Long Term Evolution (Long Term Evolution, referred to as LTE) in wireless system, terminal (User Equipment, referred to as UE) by Physical Uplink Control Channel (PhysicalUplink Control Channel, referred to as PUCCH) send dispatch request (SchedulingRequest, referred to as SR) and obtain send upstream data process as shown in Figure 1: terminal send SR; Physical Downlink Control Channel (Physical Downlink ControlChannel, referred to as PDCCH) is passed through to terminal distribution uplink scheduling authorization signaling (UplinkScheduling Grant, referred to as UL Grant) in base station; Terminal sends Buffer Status Report (BSR) according to obtained uplink authorization (or pre-configured uplink authorization); Base station according to scheduling strategy by PDCCH to terminal distribution for sending the uplink authorization of upstream data; Terminal according to obtained uplink authorization physically row shared channel (Physical UplinkShared Channel, referred to as PUSCH) send upstream data.

Send SR from terminal and bring larger delay to the process of above-mentioned (1) ~ (5) sending upstream data experience, for signaling or delay sensitive business, the delay that said process brings may have influence on throughput or user awareness.Therefore, also there is certain optimization demand in the ascending resource request method adopted in LTE in time delay, can optimize delay performance by the auxiliary uplink signal sending method based on competition.

Upward signal based on competition sends and the terminal of synchronous regime can be made directly to send upstream data when not sending SR in advance, thus save step (1) the even process of step (1) ~ (3), reduce and postpone and signaling consumption.For realizing this optimization, terminal needs to obtain the resource sending upstream data in advance.In order to not affect normal scheduling process and save ascending resource, some special Resource Block can be distributed in base station, and these Resource Block are Resource Block remaining after normal consistency, can be shared by multiple or all terminals.The terminal of carrying out upstream data transmission is needed directly to use above-mentioned resource and not in advance to base station requests, because multiple terminal may employ above-mentioned shared resource block simultaneously, thus may compete or conflict and cause upstream data to send unsuccessfully.But when system loading is lower, the probability that multiple terminal competes above-mentioned shared resource block will be in certain lower scope simultaneously, thus use this resource carry out upstream data send in most cases can be successful.One or more shared resource mark CB-RNTI, in order to the above-mentioned shared resource block of notification terminal, can be broadcasted by system message in base station in community (cell).Terminals all in community can know above-mentioned mark.Base station uses the uplink authorization of this mark scrambling by PDCCH dynamic assignment, terminal can obtain corresponding uplink authorization according to this mark, thus the resource using described uplink authorization to distribute performs upstream data transmission and add the mark C-RNTI of this terminal in community (community-Radio Network Temporary Identifier) in sent data, thus base station can know which terminal is above-mentioned data belong to.

Said process is as shown in Figure 2: in step (0), base station informs all terminals by system information resource identification CB-RNTI; The uplink authorization of this mark and correspondence thereof can be obtained by monitoring PDCCH when active state, i.e. step (1) after terminal obtains this mark; For the terminal not having dedicated uplink mandate, above-mentioned shared uplink authorization can be directly used to send upstream data on PUSCH channel, i.e. step (2).

In LTE, downlink physical control signal is carried on PDCCH, PDCCH is for transmitting Downlink Control Information (Downlink Control Information, referred to as DCI), different classes of control information is distinguished by the form (DCI format) of control information, LTE comprises the descending control information format such as format 0, format 1, format 1A, format 1B, format 1C, format1D, format 3, format 3A, and wherein DCI format 0 is for the notice of uplink scheduling authorization signaling (UL grant).Often kind of DCI signaling format all can be accompanied with cyclic redundancy check (the Cyclic Redundancy Check of 16 bits, referred to as CRC), each CRC can by corresponding Radio Network Temporary Identifier (the Radio Network Temporary Identity of implicit coded system, referred to as RNTI), namely by carrying out scrambling with RNTI to CRC, then terminal carries out blind Detecting according to RNTI to CRC, obtains the control information that it comprises.

The uplink channel resources of LTE system distributes with Resource Block (Resource Block, RB) for unit.Resource Block is for describing the mapping of physical channel (Physical Channel) to Resource Unit (Resource Element, referred to as RE).Resource Block comprises two classes: Physical Resource Block (Physical Resource Block, referred to as PRB) and virtual resource blocks (VirtualResource Block, referred to as VRB).

According to band width configuration, up can have N _rB ^uLindividual RB, a Physical Resource Block PRB accounts for N on frequency domain _sC ^rBindividual continuous print subcarrier (subcarrier), time domain accounts for N _symb ^uLindividual continuous print symbol.Wherein $N_{\mathrm{SC}}^{\mathrm{RB}}=12,$ Subcarrier spacing is 15kHz, and namely the width of a PRB on frequency domain is 180kHz.To conventional cyclic prefix (Normal cyclic prefix, referred to as Normal CP), $N_{\mathrm{symb}}^{\mathrm{UL}}=7,$ To extended cyclic prefix (Extended cyclic prefix, referred to as Extended CP), $N_{\mathrm{symb}}^{\mathrm{UL}}=6,$ Namely the length of a PRB in time domain is a time slot (slot, 0.5ms).Like this, a PRB comprises N _symb ^uL× N _sC ^rBindividual Resource Unit.In one time slot, the index of PRB is n _pRB, wherein, $n_{\mathrm{PRB}}=0,...,N_{\mathrm{RB}}^{\mathrm{UL}}-1,$ N _rB ^uLfor the PRB number that up-link bandwidth is corresponding; The index of RE to being (k, l), wherein, $k=0,...,N_{\mathrm{RB}}^{\mathrm{UL}}{N}_{\mathrm{sc}}^{\mathrm{RB}}-1$ For frequency domain index, $l=0,...,N_{\mathrm{symb}}^{\mathrm{UL}}-1$ For time Domain Index, then for conventional cyclic prefix, the structure of PRB as shown in Figure 3.A virtual resource blocks VRB has the structure identical with PRB and size.

As shown in Figure 4, the Resourse Distribute of LTE PUSCH can adopt the method for salary distribution of centralized (Localized), that is, the PUSCH of a UE occupies one section of continuous print bandwidth on frequency domain, is a part for whole up-link bandwidth.This length of tape is wide comprises one group of continuous print PRB, and the number of PRB is M _rB ^pUSCH, the continuous number of sub carrier wave comprised is $M_{\mathrm{sc}}^{\mathrm{PUSCH}}=M_{\mathrm{RB}}^{\mathrm{PUSCH}}\·N_{\mathrm{sc}}^{\mathrm{RB}}.$ Also discontinuous Resourse Distribute can be adopted (also to make discrete type distribute, distributed allocation), refer to that the PUSCH of user terminal occupies multistage bandwidth in one-component carrier wave, these bandwidth are discrete, every length of tape is wide comprises one group of continuous print PRB, be called cluster (cluster), as shown in Figure 5.
