Description
本発明の第2の態様では、ワイヤレス通信システムにおいて基地局によって実行される方法は、リソース割振り情報を含むスケジューリング情報を送信することであって、リソース割振り情報が、第1の帯域幅部分(BWP)のリソースブロック(RB)の個数に基づいて決定されたリソース表示値(RIV)を含む、送信することと、第2のBWPの中の、RIVに対応するRBセット上で、データを送信または受信することとを含み、第2のBWPのRBの個数が第1のBWPのRBの個数よりも多い場合、第2のBWPの中の、RIVに対応するRBセットの、開始RBインデックスSおよびRBの個数Lは、それぞれ、以下の値、すなわち、
- 開始RBインデックスS:{0,K,2*K,...,(NBWP1-1)*K}、および
- RBの個数L:{K,2*K,3*K,...,NBWP1*K}のうちの1つを有し、
ただし、NBWP1は、第1のBWPのRBの個数であり、Kは、2のべき乗値であり(第2のBWPのRBの個数/第1のBWPのRBの個数)に基づいて決定される。
In a second aspect of the present invention, a method performed by a base station in a wireless communication system is transmitting scheduling information comprising resource allocation information, the resource allocation information comprising a first bandwidth part (BWP ), and transmitting data on the RB set corresponding to the RIV in the second BWP, or receiving, if the number of RBs in the second BWP is greater than the number of RBs in the first BWP, the starting RB index S of the RB set corresponding to the RIV in the second BWP and The number L of RBs is respectively the following values:
- starting RB index S: {0,K,2*K,...,(N BWP1 -1)*K}, and
- the number of RBs L: has one of {K,2*K,3*K,...,N BWP1 *K};
However, N BWP1 is the number of RBs in the first BWP, and K is a power of 2 and is determined based on (the number of RBs in the second BWP/the number of RBs in the first BWP). be.
上記の問題を解決する方法として、UEは、UEの中で構成された複数のBWPがある場合、BWPごとに必要とされるRAフィールドの長さに基づいて複数のDCI長を決定し得る。したがって、UEは、複数のDCI長を想定することによってPDCCHブラインド復号を実行し得る。この方法は上記の問題を解決するが、PDCCHブラインド復号は、複数のDCI長を想定して実行されるため、UEのエネルギー消費が深刻である。
As a way to solve the above problem, the UE may determine multiple DCI lengths based on the required RA field length for each BWP when there are multiple BWPs configured in the UE. Therefore, the UE may perform PDCCH blind decoding by assuming multiple DCI lengths. Although this method solves the above problem , PDCCH blind decoding is performed assuming multiple DCI lengths, so the UE energy consumption is serious.
- オフセットは、PDCCHが受信される、コアセットのCCEインデックスから取得され得る。たとえば、offset=CCE_index mod (Nnew-M+1)である。ここで、CCE_indexは、PDCCHがマッピングされる最大のCCE_indexまたは最小のCCE_indexであり得るか、または最小のCCE_indexをPDCCHのアグリゲーションレベルで除算することによって得られる値であり得る。
- The offset may be obtained from the CCE index of the core set from which the PDCCH is received. For example, offset=CCE_index mod (N new -M+1). Here, the CCE_index may be the maximum CCE_index or minimum CCE_index to which the PDCCH is mapped, or may be a value obtained by dividing the minimum CCE_index by the PDCCH aggregation level.
別の例として、Knew>Kcurrentのとき、RIV方法を使用するUEが、周波数ホッピングを実行するように示されるとき、UEは、RAフィールドの中の1ビットまたは2ビットをホッピング関連情報として解釈してよい。ホッピング関連情報のビット数は、BWPの帯域幅に応じて変わることがある。たとえば、ホッピング関連情報のビット数(たとえば、1ビットまたは2ビット)は、新たにアクティブ化されるBWPに基づいて決定され得る。たとえば、新たにアクティブ化されるBWPの中に含まれるPRBの個数が50RB以下である場合、UEは、1ビットをホッピング関連情報と見なしてよく、50RBを超える場合、2ビットをホッピング関連情報と見なしてよい。たとえば、ホッピング関連情報のビット数(たとえば、1ビットまたは2ビット)は、現在のアクティブ化されたBWPに基づいて決定され得る。たとえば、現在アクティブ化されているBWPの中に含まれるPRBの個数が50RB以下である場合、UEは、1ビットをホッピング関連情報と見なしてよく、50RBを超える場合、2ビットをホッピング関連情報と見なしてよい。
As another example, when K new >K current , when a UE using the RIV method is indicated to perform frequency hopping, the UE uses one or two bits in the RA field as hopping-related information. can be interpreted. The number of bits of hopping related information may vary depending on the bandwidth of the BWP. For example, the number of bits of hopping-related information (eg, 1 bit or 2 bits) may be determined based on the newly activated BWP. For example, if the number of PRBs included in the newly activated BWP is less than or equal to 50 RBs, the UE may consider 1 bit as hopping-related information, and if it exceeds 50 RBs, 2 bits as hopping-related information. can be considered. For example, the number of bits of hopping-related information (eg, 1 bit or 2 bits) may be determined based on the current activated BWP. For example, if the number of PRBs included in the currently activated BWP is less than or equal to 50 RBs, the UE may consider 1 bit as hopping-related information, and if it exceeds 50 RBs, 2 bits as hopping-related information. can be considered.
別の例として、図19を参照すると、UEは、アクティブなDL BWPと1つの特定のDL BWPとの間の包含関係に従ってReferenceを取得してよく、Referenceを使用して、アクティブなDL BWPの中でブロードキャストチャネルがその中に配置されるPRBの開始インデックスRBstartを決定してよい。具体的には、アクティブなDL BWPが特定のDL BWPを完全に含むとは限らないか(たとえば、ばらばらにされるか、または部分的にオーバーラップされるか)、またはアクティブなDL BWPと初期DL BWPとの間のサブキャリア間隔が異なるとき、UEは、ブロードキャストチャネルをスケジュールするコアセットが配置されるPRBに従って、ブロードキャストチャネルがそれを通じて送信されるPRBを取得し得る。すなわち、Referenceは、ブロードキャストチャネルをスケジュールするコアセットの最小の共通RBインデックスCRBCORESETとアクティブなDL BWPの最小の共通RBインデックスCRBactiveとの間の差分として決定され得る。すなわち、Reference=CRBCORESET-CRBactiveである。したがって、アクティブなDL BWPの中でブロードキャストチャネルが開始するPRBインデックスは、RBstart=RBstart_temp+Reference=RBstart_temp+CRBCORESET-CRBactiveとして決定され得る。ここで、1つの特定のDL BWPが、基地局によってUEへの上位レイヤ(たとえば、RRC)信号で構成され得る。また、1つの特定のDL BWPが、基地局によってUEへの上位レイヤ(たとえば、RRC)信号で構成される、デフォルトのBWPであってよい。
As another example, referring to FIG. 19, a UE may obtain a Reference according to the containment relationship between an active DL BWP and one specific DL BWP, and use the Reference to A starting index RB start of the PRB within which the broadcast channel is placed may be determined. Specifically, the active DL BWP may not completely contain a particular DL BWP (e.g., may be disjoint or partially overlapped), or the active DL BWP and the initial When the subcarrier spacing between the DL BWP is different, the UE may obtain the PRB through which the broadcast channel is transmitted according to the PRB on which the core set that schedules the broadcast channel is located. That is, Reference may be determined as the difference between the minimum common RB index CRB CORESET of the core set scheduling the broadcast channel and the minimum common RB index CRB active of the active DL BWP. That is, Reference=CRB CORESET -CRB active . Therefore, the PRB index at which the broadcast channel starts in the active DL BWP can be determined as RB start =RB start_temp +Reference=RB start_temp +CRB CORESET -CRB active . Here, one particular DL BWP may be configured with higher layer (eg, RRC) signaling to the UE by the base station. Also, one particular DL BWP may be the default BWP configured by the base station in higher layer (eg, RRC) signaling to the UE.
