It is described below in claims, unless otherwise defined, otherwise all technologies used herein and section are academic Language has meaning identical with the normally understood meaning of disclosure those of ordinary skill in the art.
For purposes of illustration, some embodiments of the present disclosure will be described in the context of TD LTE.However, ability The technical staff in domain will be appreciated that, the design of some embodiments of the present disclosure and principle can be applied more generally to it is any its His suitable wireless communication system.
As described above, needing to obtain more accurate channel parameter using Beamforming technology.However, in fact, being obtained Obtaining channel parameter may be inaccurate.For example, signal interference and/or noise may introduce the error of channel estimation.In addition, letter The time-varying characteristics in road may also lead to the error of channel estimation.For example, channel measurement and downlink beamforming formed transmission it Between time interval in, channel may change.If channel variation is larger, the gain of beam forming may very little.
In TD LTE or 5G NR, detection reference signal (SRS) or Physical Uplink Shared Channel (PUSCH) can be based on Calculate beamforming weights.However, being damaged using the performance that these reference signals might have some limitations and/or beam forming It loses.
Based on SRS to measure channel, it may have a disadvantage that.SRS resource is limited.If configuration compared with More SRS resources, then band efficiency will decline.SRS resource can be determined by SRS period and SRS bandwidth.If matched The SRS period set is longer or SRS bandwidth is narrower, then can have more SRS resources.In this case it is however necessary to flower Take the longer time to scan whole bandwidth.Therefore, the quantity needs of SRS resource are limited to avoid leading due to channel time-varying The performance degradation of the beam forming of cause.Another limitation for the channel measurement based on SRS is that base station is generally to larger The UE of data buffer distributes SRS resource, and there is the UE compared with small data buffer may not be assigned SRS resource, this meeting Cause base station that may not be able to estimate the channel with the UE compared with small data buffer, to can not achieve wave beam for these UE Form gain.In addition, SRS distribution can trigger RRC (radio resource control) and reconfigure, this will need such as a few tens of milliseconds Time.If the downlink of UE and the data buffer of uplink are smaller, before completing RRC and reconfiguring, UE's Data buffer may be emptying.Due to not having data that can transmit, the SRS resource for distributing to the UE is just wasted.
Based on PUSCH to measure channel, it may have a disadvantage that.For downlink beamforming molding, The problem of channel time-varying, may possibly still be present.This is because downlink beamforming is calculated or is selected based on PUSCH.It may There is the following two kinds to happen.A kind of situation is, in a period of time, only to dispatching user facility downlink PDSCH (object Manage DSCH Downlink Shared Channel), however during this period of time, not to dispatching user facility PUSCH.In this case, base station Channel quality cannot be estimated by PUSCH.Another situation is that base station may be used to dispatching user facility PUSCH It may be different from the PRB for PDSCH in the Physical Resource Block (PRB) of PUSCH.In this case, base station cannot pass through PUSCH estimates PDSCH channel quality.
In addition, a base station or cell may service hundreds of UE in actual cordless communication network.Base station or cell Such as voice service may be provided to many UE.Due to the limitation of channel measurement as described above, SRS resource may become non- Chang Baogui, thus base station may only to larger data buffer UE distribution SRS resource to increase handling capacity, without to UE with lower data buffer distributes SRS resource.
In order to which at least one or other problems, the embodiment disclosed herein that solve the problems, such as or alleviate in the above problem mention The solution of the beam forming for the UE with various businesses demand is gone out.The disclosure is described in detail below with reference to accompanying drawings Each embodiment.
